FIG. 23 is a fragmentary top plan view of the assembly of FIG. 20 with the ball head retracted to substantially its full retracted extent to lessen the amount of the door opening.
Referring now particularly to FIGS. 1 to 6, 25 represents a door check adapted to fit over the upper edge of a door in a tight fitting manner while providing a forwardly extending nose portion 26 with a ball head formation 27 adapted to be fitted into a groove 28 of a keeper 29 that can be secured to a door frame or wall surface 31 either by adhesive or as shown in FIG. 6 by a screw 32 entering a hole 33 in rear of the groove 28.
A door 34 may have different thicknesses but the present door check is adapted to accommodate the different thicknesses and at the same time provide an easy separation of the door check from the door for adjusting the same along the length of the upper edge of the door. The nose portion 26 extends at right angles to a front depending portion 35 which cooperates with a bendable leg portion 36 which extends laterally across the upper edge of the door as indicated at 37 and has an outwardly and downwardly reverse bend to which handle portion 36 extends. The inner face of this bend 38 has a rounded engaging surface 39 that will engage the door surface in accordance with the thickness of the door to provide a gripping and clamp action between the depending portion 35 of the nose and the depending handle portion 36 which extends downwardly and outwardly from the surface of the door so that it can be readily gripped to spread the handle portion when the door check 25 is being assembled upon the door or removed therefrom. The lower end of the depending portion 35 of the nose engages with the opposite face of the door and is rounded at its lower end as indicated at 41 to facilitate the assembly of the door check 25 upon the upper edge of the door and when taken with the rounded surface 39 of the handle portion 36, the door check can be easily slid into engagement over the upper edge of the door and the laterally extending portion 37 having its underface enaging flush with the upper edge of the door. 7
In FIG. 3, there is shown a handle portion 36' which has a flat inner face 42 for engaging the door surface and to provide for a greater frictional area of engagement therewith. Instead of line contact with the surface of the door as at 39, a full face area 42 will engage the door surface and provide for frictional engagement therewith.
The width of the door check portions 26, 35, 37 and 36 are sufficiently great to give a sturdy connection with the door so that the nose portion 26 will extend rigidly forwardly from the door. By utilizing the ball head 27 an angle engagement can be made with the groove 28 of the keeper member 29 as best seen in FIG. 4. This keeper 29 can be located on the door frame or wall surface 31 ateither a location close to the hinge connection of the door with a door frame as shown full in FIG. 4 or as shown in dotted lines to an extended position more removed from the hinge section of the door with the frame. This being well illustrated at the left side of the FIG. 4.
On the right side of FIG. 4 there is an illustration made of the door 34 being in a dotted line position of fully open position and wherein a keeper 29 is of considerable length that will run across the full extent of the door and adapted to receive the ball head 27 at any location therealong. In this means the keeper has been provided to keep the door open or fully open and by simply removing the door check 25 from its position on the door 34 as shown at the left side of the Figure and causing the door check to be reversed upon the upper edge of the door and thereby permit the door to be held to its fully open position and over center from the hinge. A long keeper 29 can be used as well as a short keeper or upon the door frame. If it was desired to have the door closed so that there is but a small amount of opening and even less than in the dotted line position as shown at the left side of FIG. 4, the door check 25 can be reversed upon the door edge and the curved portion 38 serve as the nose for engaging the door frame to at least hold the door against closing movement and which will be particularly effective if the door itself is hingedly spring biased toward a closing position. In this way of reversing the door check 25 on the door and with the door being more aligned with the door opening the door can be kept open a little more than ajar or fraction of an inch if the reverse door check 25 is at the extended position that is shown in dotted lines at the left side of FIG. 4 and more remote from the door hinge. As seen in FIG. 5 it will be noted that the nose portion 26 and more particularly the ball head portion 27 can engage the groove 28 of the keeper 29 from various angular or universal positions. Adhesive 43 as shown in FIG. 5 upon the keeper 29 for effecting the engagement of the keeper 29 to the door frame or wall surface 31. The nose portion 26 has upwardly and downwardly flared edges 44 and 45 that provide for an enlargement upon the nose portion and can make engagement with the door frame in situations where no keeper for the ball head27 is used, as by direct engagement with the inner top surface of the door frame.
It should be apparent that the keeper 25 is so shaped and formed that it can be easily slipped over the top edge of the door or removed from the same and that the handle 36 used in placing the door check upon the door is easily available and outwardly and downwardly inclined to permit the fingers to be extended under the handle 36 to effect the pushing of the door check from the door and also the pulling of the door check downwardly over the upper edge of the door.
Referring now particularly to FIGS. 7, 8 and 9, 50 represents generally a door check that is designed primarily for holding open doors which are spring biased towards a closing position, whereas with the above first form of the invention the door check will hold the door open against both further outward movement and inward movement by engagement of the ball within the groove 28 of the keeper 29. This keeper 50 is provided with simply a plain nose projection 51 that extends forwardly from an upright portion 52 to which a depending handle clamp portion 53 extends to locate the door check 50 downwardly over the upper edge of a door 54. This door 54 is connected to the frame either through a spring hinge or by a spring connected outwardly of the hinge for connection to the door frame so as to normally keep the door in its closed position by means of a spring. This door check is inserted for engagement with its nose portion 51 against a door frame or wall surface 55. A sponge rubber bumper is preferably adhered to rounded nose end surface 57 by releasing a cover sheet 58 from a tacky adhesive layer 59 and this sponge rubber bumper 56 will keep the door frame surface from becoming marred if the door check 50 is made of metal and at the same time will quiet any bumping action that may be made by the door opening and closing as when a person may come through the open door.
As with the previous form of the invention the door check 50 can be moved along the upper edge of the door 54 to a dotted line position as' shown in FIG. 9 so as to keep the door open to a less extent as when the door check 50 is moved more remotely from the hinge.
The lower end of the vertically extending portion 52 is rounded outwardly and upwardly to provide a rounded surface to facilitate the assembly of the door check 52 upon the door as when the handle 53 is gripped to pull the same downwardly or to push the door check upwardly. Its rounded lower end as indicated at 61 and has a central slot 62 to allow a rule spring 63 to be engaged by a connecting projection 64 upon the rolled up end 61 and this rule spring 63 can be extended to have engagement with the opposite side of the door frame so as to hold the door against further outward displacement and to adapt the door check 50 for use with doors where the door is not spring biased to a closed position or where the spring is weak. It may thus be apparent that with this rule spring 63 that the keeper 50 is readily adapted for use with doors where there are no springs to keep them closed as with the door of the form of the invention shown and above described and which utilizes for this purpose the tight fitting engagement of the ball head of the door check with the groove.
The handle portion 50 extends from the rear face of the upright portion 52 to overlie the top edge of the door and is provided with a reversely bent portion 66 to provide for a door face engaging surface 67 upon the inner face of the handle 53. The handle 53 will extend outwardly so that the fingers can be extended under the same to grip the door check for attaching the same to the upper edge of the door or for removing the same for adjustment along the upper edge of the door. The rounded surfacesprovide by the outwardly curved end 61 of the upright portion 52 and the rounded surfaces 67 of the handle 53 makes for good engagement with the door surfaces when effecting the attaching of the door check and the removal of the same from the door.
In FIGS. 13 and 14 there is provided a door check in dicated generally at 70 that is of the bumper type and adapted particularly for use with doors which are spring biased to a closed position, but wherein there is provided an eccentric bumping member 71 that is re tained on the outer end of a laterally extending nose portion 72 and a lateral slot 73 thereof and for rotation by a vertically extending large diameter pin 74 that upon engagement with the inner periphery of an opening and by friction engagement further of the top and bottom faces of the member 71 with the top and bottom faces of the slot 73, the eccentric member 71 can be adjusted and be retained in its adjusted position to provide an elongated portion extending outwardly from the end of the laterally extending nose 72 or moved to dotted line positions to provide a more shortened connection of the laterally extending nose portion 72 with the door jamb surface. By moving or pivoting the eccentric element 71 as indicated in FIG. 14 by the arrows and to the dotted line positions the extent to which the door is held open can be varied to some small extent without the need for moving the door check along the edge of the door so that the door check can generally be kept in its one location upon the upper edge of the door.
This door check 70 has a vertically depending portion 75 that is thickened at its lower end as indicated at 76 to provide for a rounded engaging surface 77 that will oppose a rounded surface 78 provided by a reverse bend 79 of a depending handle clamp portion 78 that is connected to the depending portion 75 as when the handle 78 is extended laterally over the upper edge of the door to make clamping engagement on the opposite sides of the door so that the nose portion 72 extends forwardly for engagement of its eccentric member 71 either extended as shown in full in FIG. 14 or retracted by turning the same in the direction of the arrows to dotted line position. This form of the invention makespossible the extension of the nose end of the door check.
In FIGS. 15 and 16, 80 represents a still further form of the invention that has a forwardly extending nose portion 81 and a downwardly extending vertical portion 82 depending therefrom that has a series of rollers 83 located in a slot 84 on the inner face of the depending portion 82 so that rolling engagement can be effected of this portion 82 with the door surface and on a clamp arm 85 and in the reverse bend portion 86 thereof is a roller 87 having rolling engagement with the opposite side of a door88. These rollers will like their curved surfaces facilitate and make easy the attachment of the door check 80 to the upper edge of the door or the removal of the same. Each time the door check 80 is adjusted laterally over the top edge of the door it can be easily and readily removed. This form of the invention thus provides for an improved clamp engaging means that can be used with all of the different forms of the invention.
In FIG. 19 there is shown a fragment of a nose portion 91 of a door check having a threaded end opening 92 into which is extended a threaded shank 93 of a ball head that can be used with the first form of the invention shown in FIGS. 1 to 6 and which will obtain the same effect as the eccentric member 71 of the form of the invention shown in FIGS. 13 and 14 so that an adjustment can be madeof the ball without removing the door check from the upper edge of the door; Simply by unthreading the shank 93 from the opening 92 the ball head 94 can be extended to a greater extent and when threading the same inwardly it can shorten the overall length of the nose assembly of the door check.
In FIGS. 17 and 18 there is shown a door check indi cated generally at which includes a forwardly extending nose portion 101 and a depending attaching portion 102 similar to the attaching portions of j the other forms of the invention, but not shown, that has a reduced section forward end 103 with a threaded opening 104 therein into which is threaded a ball headed bolt 105 having a ball head 106 providing for a universal connection of a ball shaped opening 107 with an engaging plate 108 that has a Velcro like formation 109 on forward face adapted for flush engagement with a cooperating Velcro member 110 that is adhered by adhesive 111 to the door frame. The member 108 is held outwardly from the reduced section and 103 by a compression spring 112 reacting between the reduced section and 103 and a washer 113 engaging with the inner face of the member 108.
It will be seen that by the universal connection of the member 108 it can readily adapt itself for engagement with the member 110 and that by this Velcro engaging members 109 and 110, the door check 100 will hold a door when assembled upon the upper edge thereof against outward displacement from the door frame as well as against closing movement of the door.
Referring now particularly to FIGS. to 12, there is shown a door check 120 having substantially the same construction as the first described form of the invention except that instead of using a ball head 27, opposing ball jaws 121 and 122 are used for engagement with a beaded keeper 123 that is adhered to a door frame or wall surface 124 and is adapted to be gripped by the jaws 121 and 122 as shown in FIG. 11 so that the door check when fixed to the door will hold the door against both outward and inward displacement in the same manner that the door check 25 of the first form of the invention functions.
The jaw portions 121 and 122 are provided upon the forward end of a laterally extending nose 125 from which a depending clamping or attaching portion 126 extends, extending rearwardly and outwardly from the depending portion 126 is a handle clamp portion 127 by which the door check 120 is fixed to the door and removed therefrom, the handle clamp portion being bendable from its connection with the depending portion 126 and providing a rounded engaging face 128 for engagement with the door face. The lower end of the depending portion 126 is rolled upwardly as indicated at 129 to provide a rounded lower end face for facilitating the vertical engagement of the door check 120 with the forward face of the door.
Referring now to FIGS. to 23, there is shown a form of the invention indicated generally at 130, wherein a ball head 131 can be adjusted forwardly and rearwardly from an upstanding portion 132 from which a forward clamp portion 133 extends so that the adjustment of the ball head 131 can be made from a location in back of the door rather than having to make the adjustment by extending a hand forwardly to rotate the ball head as in the form of the invention shown in FIG. 9. The upright portion 133 has the usual spring clamp handle portion 134 that is similar to the portions 36, 53, 127 of the other forms of the invention already described.
This ball head 131 is provided upon an enlargement 136 from which there rearwardly extends a rack rod shank portion 137 that extends through an elongated opening 138 in the upright portion 132 so that its rack teeth 139 will be engaged by a downwardly bendable catch 141 whereby the ball head 131 will be held at any outwardly adjusted position and extent forwardly from the upright portion 132 depending upon the extent to which the door needs to be opened. This adjustment is made from back of the door by simply pressing down on the catch 141 and pulling or pushing on the shank 137 that extends rearwardly from the elongated opening 138 of the upright portion 132.
In order to steady the rod shank 137 and the ball head 131, right and left articulating linkages 142 and 143 are connected between a forwardly extending flange 144 and the enlarged head 136. Pivot pins 145 and 146 that connect the linkages 142 and 143 to the flange 144 and pivot pins 147 and 148 connect the linkages 142 and 143 to the head 136.
It will thus be seen that the ball head 131 can be worked in or out from the rear of the door check so as to vary without removing the door check from the door the extent to which the door is open, and thereby permit the door check to be kept at one location upon the door. The ball head 131 will engage with a grooved keeper, such as shown at 29 in the first form of the invention. Thus with this arrangement the door is held against outward as well as closing movement upon its hinge and is checked in this manner in two directions.
The various parts of these door checks according to all forms of the invention can be made out of plastic in order to render them inexpensive to manufacture and preferably such that can be readily molded or extruded out of plastic and wherein they will have soft engagement with the surfaces of the door and the door frame and eliminate thereby scratches upon the door and on the door frame.
In the form of the invention, particularly as shown in FIGS. 7, 8 and 9, the door check can be used as described with the first form of the invention either as it is shown in FIG. 7 to extend forwardly and have the engagement with the nose portion 51 or its sponge rubber head 56 or the door check 50 can be reversed upon the door so that the door will engage with the door jamb by its rounded portion 66 of the depending clamp handle 53. In this manner the door can be held open as it is extended along the door either close to the hinge or outwardly up to three inches at its outer edge and if it is desired to have the door open to a greater extent then the door check 50 will be applied so that the nose portion 51 extends forwardly and a greater opening beyond three inches can be effected depending upon the location of the door check relative to the hinge on the door.
