Abstract
A housing, mountable on a panel, provided with a stepped bore therethrough into which a slidable bar is positioned to extend beyond each side of the housing. One end of the bar is provided with a finger-grip handle so that the bar may be pushed and pulled through the housing into and out of a predrilled bore in a second, relatively movable panel. When the bar is pulled toward the user and out of the predrilled bore, a larger diameter section thereof abuts a step in the housing bore to prevent the bar from being completely removed. When the bar is completely pushed in, a sphere may fall into a fillet on the bar. Pulling on the bar lightly will cause the fillet to push the sphere out of the way so that the bar can be withdrawn. A flange or cam, which may be rotated by means of a key lock, may be so located within the housing that it can positively retain the sphere against the fillet in order to positively prevent withdrawal of the bar.

sum 1 95 3 PATENIEUA'PR 1 siis KEYED FIXED noon LOCK BACKGROUND OF THE INVENTION Houses and other buildings constructed and remodeled in accordance with modern architectural techniques are being provided with a maximum number of windows and other lightadmitting devices. Modern living habits have also given rise to a requirement that houses be well-suited to indoor-outdoor" living. These facts have resulted in the construction of a large number of buildings having sliding glass doors which may be easily opened so that people and air can quickly and easily move in and out of the building.

Unfortunately, the extended use of the sliding glass doors, as well as other openable fixtures such as large windows, marine hatches, etc., has also increased the vulnerability of such buildings or structures to illegal and/or undersired entry by humans and animals. Many of the closure devices are susceptible to being quickly and easily jimmied open and, in fact, cannot be locked against being opened unless they are in the fully closed position. In other words, the closure cannot be left even partially open for the passage of air without creating the danger of unauthorized entry unless an additional locking device is provided. For the sake of simplicity, the remainder of this discussion will refer to the wellknown sliding glass doors by way of illustration. Thus, the terms fixed panel" and movable panel will be used. However, the reader should bear in mind that the present invention and the problems which it solves are not limited to such doors. In other words, the solutions herein proposed by this invention for the problems now being discussed are equally applicable to the locking against relative parallel movement of any elements, whatever their natures or use.

The problems described above have resulted in the creation of a wide variety of supplemental locks or locking devices which will prevent the door from being jimmied open whether the movable panel is fully closed or partly opened.

Some of the supplemental locking devices employ a variety of spring and/or thread systems. For example, some locking devices have been provided which basically comprise rods which are mounted between the door jamb and the rear end of the movable panel. Often, such rods may be adjusted to a variety of positions so that the panel may be locked in a fully closed position as well as in some predetermined maximum opened position. While these devices do prevent the movable panels from being opened beyond a predetermined position, they do not fully prevent unauthorized entry into the structure since, in the case of most such closure members, it is quite easy to manually lift the movable panel away from its lower track, tilt it slightly away from the track, and remove it from the wall entirely. In other words, these devices can be defeated by moving the panels perpendicular to their normal direction of motion relative to the fixed panel.

Other devices have been disclosed which comprise a base member which may be mounted on a door jamb or other structure so that a slidable rod may pass into a hole formed in the frame of the movable panel. Some of these devices have been provided with spring-biased elements which tend to drive the slidable rod into the hole in the panel. The rod must be withdrawn against the biasing force before the panels can be moved relative to one another. If the spring should break, the rod may easily slide out of the hole in the panel due to vibration, etc. Further, such locks have only presented a nuisance resistance value in that a determined housebreaker can very simply cut a small hand-hole in the glass, reach into the building, and pull the rod out of the hole in the panel. When this has been accomplished, the device is no longer effective to prevent relative movement between the panels.

In U.S. Pat. No. 3,695,657, assigned to the Assignee hereof, there has been disclosed a novel slide lock device comprising a base fixture having a pair of upstanding ears through which a locking bar may be slidably moved between extended and withdrawn positions. The bar may be provided with one or more fillets so that the shackle of a padlock can be passed over the bar and between the upstanding ears to prevent movement of the bar.

In some applications, it is aesthetically undesirable to have a padlock mounted on such a locking device. Also, when the padlock is removed from the device for its normal day-to-day operation, a location must be provided for storage of the padlock so that it does not become lost between uses. It will quickly be realized that if such a lock is provided for each of many closures along the ground floor of a building, the storage of the required padlocks becomes a horrendous problem.

Consequently, although the slide lock illustrated in U.S. Pat. No. 3,695,657 is satisfactory in many situations and provides several highly desirable features which may outweigh any deficiencies which it may be considered to have, none of the prior art devices has proven to be totally acceptable. They do not sufficiently prohibit break-ins, are costly, and/or are inconvenient to use because, for example, they require additional structure, such as padlocks, to provide complete security.

Another disadvantage inherent in many of the prior art locking devices is that they must be mounted in substantially predetermined positions relative to the door, thereby allowing the building owner little or no option as to the placement of the lock. In other words, some of these devices require that they be mounted on the door jamb at the sides of the door, others at the top or bottom of the door, and others in relatively predetermined locations. Preferably, such a device should be manufactured in such a way that the building owner has complete freedom in selecting the mounting location to suit his own convenience. In other words, it might be desirable to mount the lock on the fixed panel, the movable panel, or the door jamb. Similarly, it might be desirable to mount the lock in a high position so that it can be reached only by adults or in a low position so that it can be reached by everyone having occasion to use the door.

Accordingly, it is necessary and desirable to provide a door lock of the type described which can be mounted in nearly any position, is very compact so as to be unobtrusive and difficult to attack, can be positively locked to prevent unauthorized opening of the door, and can be-locked in such a manner that only authorized persons are able to unlock it. Further, it is preferred that the device be lockable without requiring a separate lock for which storage must be provided when it is desired to leave the device in an unlocked configuration.

SUMMARY OF THE INVENTION The present invention may be embodied in a device A from being pulled completely out of the housing by which achieves each of the above-described desired results without compromising the integrity of the primary function of preventing relative planar movement between two parallel, closely adjacent structures.

In its preferred embodiment, the present invention may be formed of a relatively small housing which may be suitably positioned in any desired location in relation to the two relatively movable structures. In one comparatively simple form, the device may be constructed of a housing formed by a pair of mating castings which cooperate to capture and hold a keyoperated cylinder lock having suitable tumblers. On the inner end of the cylinder, a cam may be suitably fixed so as to be rotatable when a key is inserted in the cylinder to actuate a detent within the housing.

In any of the various preferred embodiments, the detent may comprise a sphere which may be actuated by the cam into contact with a suitably located fillet on a locking bar or rod which is slidably mounted and extends through the housing. Thus, when the cam forces the sphere against the fillet, the locking bar cannot be moved in any direction and, by forming it to be of suitable length to extend into the movable panel, the movable panel can be fixed in position relative to the object to which the housing is fixed.

By providing the fillet to be of rather shallow curvature, when the lock cylinder is turned so that the cam is not exerting a positive force against the sphere, an operator pulling on the exposed end of the rod can force the sphere out of contact with the fillet and to pull the rod out of a predrilled hole in the movable panel. Of course, the housing could be mounted on the movable panel and the rod made to extend into the fixed panel with essentially the same result.

A variety of ways to mount the device in such a manner that it cannot be removed without substantial destruction to the door may be made available by suitable configuration of the housing exterior. Thus, it will be realized that apparatus embodying the present invention may be formed of a relatively simple construction which is small enough to be unobtrusive. Consequently, it can be mounted in nearly any position and, preferably, in a position in which it cannot be attacked effec tively without substantially destroying the door.

Since the device is locked by means of a key which turns a cylinder fixed in the housing, there is no need to provide a special lock or padlock whenever a positive lock is required and. consequently, there is no need to provide any storage for such padlocks when they are removed. Also, since the device does not require the use of springs, etc., it is substantially maintenance-free.

Additionally, it is a relatively simple matter to provide a plurality of cylinder-locks with the same or similar tumbler or disc combinations so that a large number of the devices can be locked and unlocked by means of a single master key and/or an individual key for each lock. Further, proper design of the housing dimensions will allow the rod to have a length sufficient to prevent lifting of one of the relatively movable structures relative to the other so that, for example. the movable panel of a door cannot be lifted off its track and pulled perpendicularly away from the fixed panel.

On each side of the fillet, the rod may be provided with a distinct diameter. For example, the end of the abutment with a shoulder in the housing. On the other hand, that portion of the rod which can pass through the shoulder may be provided with a finger-grip knob thereon which will positively prohibit the rod from being pushed so farinto the housing that it cannot be retrieved when it is desired to allow the panels to move relative to one another.

It will become apparent to those skilled in the art from the above description that the rod can be pushed through the housing and into the predrilled opening in the opposite panel without further action being necessary to prohibit relative movement. On the other hand, when it is desired to prevent unauthorized persons from pulling the rod out of the predrilled opening, a key may be inserted into the cylinder and turned, thereby actuating the detent against the fillet to prohibit movement of the rod. When this is accomplished, even if a housebreaker should cut a small hand-hole in the glass, he will still be unable to pull the rod out of the predrilled opening. Thus, the device increases the integrity of the area to be protected.

If desired, the bar may be provided with a pair of fillets; one may be used to lock the bar in the predrilled opening and the other to prevent its being pushed into that opening when it is desired to positively prohibit unauthorized locking of the door.

The present invention presents a true advancement in the art of locking devices and should not be considered to be limited to the embodiments described and illustrated here since these are merely considered to be presently preferred embodiments, while the scope of the invention is defined solely by the claims.

DETAILED DESCRIPTION In order to more clearly understand the full import of the invention, it is necessary to discuss various embodiments thereof. These embodiments will also clearly illustrate that the invention is not limited to a single structure but includesa large number of distinctive forms. Regardless of the form, the purpose of the present invention is to provide a novel apparatus for preventing relative movement between a pair of panels 11 and 13 as illustrated in FIG. 1. For the sake of this discussion, it will be assumed that panel 11 is fixed and that panel 13 is movable and that both comprise panels of a glass door. It is important to note, however, that either or both of the panels could be movable and the structure which is to be locked against relative movement could be any structure of a similar nature, i.e., relatively movable in parallel planes.

In any event, panel 13 may be provided with one or more predrilled openings or apertures 15, 17 through which a rod or locking bar 19 may be selectively extended depending upon the relative positions of the panels. In the embodiment of FIG. 1, the locking bar 19 passes through a housing 21 which may be suitably mounted in any desired position on the panel 11. In this illustrated embodiment, the housing 21 may be provided with a pair of bores 23 which are coaxially aligned with a pair of counterbores 25 so that a shoulder is formed between the bores and the counterbores. Accordingly, the heads 27 ofa pair of machine bolts or screws 29 may seat against the shoulder to hold the housing against the panel 11 when the bolts 29 are threaded into the adjacent edge of the panel.

Thus, with the housing 21 suitably fixed to the panel 11 and the bar 19 extended through a coaxially located opening in the panel 13, relative movement in parallel planes of the two panels is positively prohibited.

Many sliding glass door panels are provided with structural retaining bolts 31 near the corners thereof so that the panels can be fabricated from independent frame elements. In order to allow the housing to be mounted in any desired position, it may be provided with recesses 33 on either side thereof as illustrated in FIG. 2 so that clearance will automatically be provided between the housing and any obstruction such'as the head of bolt 31. Thus, the device may be installed in nearly any practical location relative to the panels and- /or the door jamb in which the panels are mounted.

In order to more Clearly illustrate some of the specific details of this embodiment, FIG. 3 comprises a sectional view of the structure and shows the rod 19 to have a first locking portion 37 which is of a diameter to freely pass through a bore 39 in the housing. The bore 39 extends through the housing and ends at a radial shoulder 41 which terminates at the periphery of a bore 43 of reduced diameter. A second or guiding portion 45 of the rod is provided which is of a smaller diameter than the locking portion 37 such that it will freely slide through the bore 43. Intermediate the sections 37 and 45 of the rod 19, a fillet 47 may be formed for a purpose to be described. A review of the drawing will clearly illustrate that the rod 19 can be pulled toward the right until the side of the fillet adjacent the locking portion 37 of the rod abuts the shoulder 41 and prevents further axial movement thereof.

On the outer end of the guiding portion 45 of the rod, a knurled knob 49 may be suitably mounted, such as by threading or by being staked thereon. When the rod 19 is pushed to the left, as viewed in FIG. 3, its movement will be limited by contact of the knob 49 with the surface of the housing 21. Consequently, axial movement of the rod relative to the housing 21 is limited by contact of the rod with various portions of the housing. Accordingly, when the rod is in the position illustrated in FIG. 3, the locking portion 37 will extend through a suitable predrilled opening in a panel, such as that illustrated at in FIG. 1. On the other hand, when one wishes to allow the panels to be moved relative to one another, the knob 49 can be pulled to the right,-as seen in FIG. 3, until the large end of the fillet contacts the shoulder 41, thereby removing the locking portion 37 from the aligned aperture.

In order to ensure the security of persons or property within an area bounded by the panels, it is desirable to provide appparatus by means of which the rod can be locked in one position or the other so that unauthorized persons cannot take action which would allow the panels to be moved. In this embodiment, a sphere or detent 51 may be provided which is freely movable through a passage 53 which intersects bore 39. The sphere 51 is illustrated as being seated against the rod due to grav ity, but it will be realized by those skilled in the art that it could be spring-biased against the rod, if desired. In manufacturing the housing, the passage 53 may extend all the way to the periphery thereof so that the sphere 51 may 'be inserted thereinto just before the rod 19 is mounted in the bores 37 and 43. Thus, the detent 51 is prevented from being removed from the housing The detent may cooperate with the fillet 47 to lock the bar in the extended position shown or, if desired, may cooperate with a fillet 55 so that the bar can be locked in the withdrawn position. Preferably, the fillets 47 and 55 should be formed in rather shallow configurations on the rod so that pushing or pulling of the latter will force the detent 51 away from the rod in the passage 53 a sufficient distance to allow the rod to pass when positive locking is not required. In other words, move ment of the rod will thus be inhibited, but not prohibited.

However, in order to prohibit this movement, if desired, a suitably located actuating cam 59 may be fastened to the end of a shaft 61 mounted in a tumbler or disc cylinder 63 which may be actuated by any suitable means, such as a key 65. The cylinder 63 may be centrally located within a bore 64 having suitable inner surfaces A and B machined for desired clearances.

The cam 59 and detent 51 cooperate in the manner illustrated in FIGS. 4 and 5. In FIG. 4, the cam 59 has been rotated so as to positively lock the sphere 51 against one of the fillets on the bar 19. On the other hand, in FIG. 5 the cam 59 has been shown rotated to a position such that the bar 19 can be pushed or pulled through the housing and freedom of movement is ensured by the clearance between the cam and the sphere.

Thus this invention comprises apparatus for preventing relative parallel movement between adjacent panels, in the form of a relatively small housing which may be suitably mounted in any location relative to the movable panel member. The device may be actuated to prevent persons on the outside of the panels from operating them by pushing the locking bar through predrilled apertures without actuating the cam against the detent. On the other hand, persons on either side of the panel can be positively prohibited from operating the panels. The locking cylinder can be key-actuated to rd tate the cam against the detent, as illustrated in FIG. 4. thereby forcing the detent against the selected fillet in the bar to positively prohibit movement thereof.

In order to prevent removal of the cylinder 63, a set screw 71 may be passed through a passage 73 in the housing 21. Preferably, the access passage 73 intersects the axis of bore 43 so that when the bar 19 is installed in the housing, there can be no access to the setscrew.

Since the housing can be mounted in any suitable location, such as at a corner of a panel, and since the in-' ternal workings thereof are not exposed to any normal tools, it can be seen that if the bolt heads 27 are formed so as to comprise one-way bolts, the device is substantially impervious. V

The provision of a lock which remains in the housing at all times for selective actuation allows the device to be quickly and simply operated without requiring installation of a padlock or other device and the necessity of providing a location for storing the padlock when it is not in use.

Referring now to FIGS. 6 and 7, an alternative embodiment of the present invention has been illustrated for use with the panels 11 and 13. With respect to this embodiment, those elements which are substantially identical in function to those described with reference to FIGS. 1-3 have been provided with identical reference numerals, each preceded by the numeral 1. Thus, housing 21 is now described as housing 121, etc.. and no further description thereof is necessary.

In this embodiment, a clip 114 may be provided which fits over the head of the structural bolt 31. The clip may be fastened to the end of the panel 11 by any suitable means such as screws 116 which pass through the clip and through bores in the end of the panel. Extending perpendicular from the face of the clip, a plate 118 may be provided which extends into a slot or kerf 120 in the housing 121. Plate 118 may be formed integral with or suitably fastened to the clip 114 so that there is no possibility of relative movement therebetween. A plurality of apertures 122 extending through the housing may be coaxially aligned with similar apertures in the plate. When the apertures in the housing and the plate are aligned, suitable roll pins 124 may be extended therethrough in the manner illustrated in FIG. 6.

The housing is thus effectively locked to the clip 114. In this manner. the housing 121 can be effectively and permanently fastened to the end of the panel 11 in such a manner that it also is impervious.

The cylinder 163 may be fixed within the housing 121 in the manner similar to that shown in FIG. 3 or, if desired, the plate 118 may extend into a kerf 125 in the side of a cylinder as illustrated in FIG. 6. Thus, the plate 118 can serve the dual purpose of locking the housing 121 to the end of the panel 11 as well as locking the cylinder 163 within the housing.

Referring now to FIGS. 8 and 9, another embodiment of the invention has been illustrated. In this embodiment, elements which are substantially identical to those illustrated and described with reference to FIGS. 1-3 have been provided with like identification numerals, each preceded by the numeral 2. Additional discussion thereof is not necessary here. In this embodiment. the housing 221 may be formed from two mating portions 210 and 212 which may, for example, be castings. A plurality of locating apertures 214 may be formed in one of the sections of locating apertures 214 may be formed in one of the sections and a like plurality of locating pins 216 may be formed in the other. Thus, when the sections 210 and 212 are put together, the pins and apertures will mate so that the castings will be properly aligned. Further, by providing the clearances between the pins and the castings to be relatively minimal, a tight and substantially permanent fit of the two sections may be ensured.-

In order to further facilitate the mating capability of the two sections, either or both may be provided with a lip 218 thereon which cooperates with the peripheral edge of the opposite section, thereby ensuring parallel movement when joining the sections and also prohibiting access to the juncture.

In this embodiment, the bore 264 in which the cylinder 263 is mounted may be provided with a pair of opposed lips 220, 222 which may be inserted into cooperative kerfs 224, 226 formed in the edges of the cylinder 263 as illustrated in FIG. 9. Thus, when the sections 210 and 212 are joined, the cylinder 263 will be fixedly held against axial or rotational movement in the hous- Also, the use of the mating portions 210, 212 allows the detent 251 to be located in a passage 253 which does not extend to the periphery of the housing. Thus the integrity of the device is still further ensured.

If the bolts 229 are provided with one-way heads as previously discussed, they will not only serve to fasten the housing in place on the end of the panel, but will also, when thus threaded into the panel, serve to fasten the sections 210 and 212 of the housing together so they cannot thereafter be separated.

Thus it can be seen that the invention set forth in the claims of this application may be embodied in a plurality of distinctive devices, various embodiments having been illustrated here merely for the purpose of disclosing various structures which may be utilized to mount the device or to mount portions of the hardware therein. It will be quickly realized by those skilled in the art that additional embodiments of this structure utilizing different detents, locking and detent actuating structures, etc., may be similarly provided without exceeding the scope and intent of the invention. It is. of course, intended that all such embodiments be included within the scope of the protection provided by the claims. hereof.
