SCHIMEK DOOR MOUNTING I I I I l- I I I I I I I I sept. 4, 1962 Filed Oct. 15, 1959 QN amm a@ j Q INN MI UX MII I@ g ttes This invention relates to door mountings, and more particularly to a door mounting for slidably 'and pivotally mounting a door or other closure for selective movement between a closed position and an open position which is substantially parallel to the closed position.
The present invention is a icontinuation-in-part of my copending application, Serial No. 842,781, filed September 28, 1959, now Patent No. 3,019,492, issued February 6, 1962 and similarly provides for opening of a door or closure by pivoting it outwardly of the door opening therefor and then sliding vthe door in parallel relation to its initial position, closing of the door being accomplished in the reverse manner, whereby full use of the door opening is afforded and very little space is required to accommodate the movement of the door.
In accordance with the invention a pair of arms are pivotally connected to one side of a door frame or jamb in laterally fixed relation thereto, and are pivotally connected at their outer ends to the door for slidable movement along a track -secured across the door. This construction eliminates the use of the track across the door frame which was utilized with my said copending application, and further increases the amount of space available yat the door opening as a result of `the elimination of the arm slidable in the track across the door frame. Thus, in one embodiment of the invention, the door mounting may be used with a car door or doors so that the mounting is positioned at the bottom of the door jamb; and a single arm may be used if desired at the midpoint of the ja'mb. Thus, where two car doors are used on each side of the car, i.e., in a sedan, the entire door space may be available and the doors in their closed positions may be disposed in abutting relationship at their inner edges.
Accordingly, it is an object of the present invention to provide a door mounting which is exceptionally simple and economical in construction and which may be used in a variety of applications with complete reliability.
Another object of the invention is to provide a door mounting yas described which permits the entire door opening to be used, as `compared with previous sliding door constructions Iin which the door occupied at least a portion of the opening even in its open position.
Another object of the invention is to provide a door mounting as described wherein a pair of door mounting arms may be pivotally and xedly secured at a desired vertical location on a door jamb for giving rugged support to a door slidably connected with the outer ends thereof.
Other objects and advantages of the invention will become apparent as the description proceeds in accordance with the drawings in which:

As shown on the drawings:
Referring now to the drawings, FIGURE 1 shows a pair of doors 10 and 12, each having upper and lower door mounting structures 14 and 16 and 18 and 20 formed in accordance with the presen-t invention. However, the invention permits the use of the door mounting means 14 through 20 in any desired location vertically on the doors 10 and 12, as hereinafter described, and also eliminates the use of door mounting arms on both sides of the doors 1t) and 12 so that an increase in available space is afforded.
Referring now to FIGURES 2 through 5, a single door structure 22 is shown pivotally and slidably supported in a door frame 2-4 by a door mounting `26 according to the invention. Although the door mounting 26 is illustrated as being positioned at the bottom of the door structure 22, it will be appreciated that it may also be positioned at other vertically spaced positions, as stated, and may be used in conjunction with a similar vertically spaced door mounting, using either a pair of arms or a single arm, as shown in the construction of FIGURE l.
The door mounting 26 preferably includes a door mounting bracket structure 2S which may have a Z-shaped configuration cross sectional'ly as shown in FIGURES 2 land 3 and may have a rearwardly and downwardly turned flange 4structure 31) for engaging a mounting structure 32 at a lower inwardly extending flange portion 34 thereof as best seen in FIGURE 5.
In accordance with the invention, a pair of support arms 36 and `33 are pivotally moun-ted within the mounting structure l32. by means of inner bosses 4tland 42 received within :a groove structure 44 in the mounting element 32, and hingedly secured therein by pivot pin elements 46 and 48. Washer means ISil and 52 may be provided Within the groove structure `44- and above and below the pivot bosses 40 and 42, `and in order to accommodate pivotal movement of the arms 36 and 38, the re' taining bracket 28 has an upper -depending flange 54 terminating in spaced relation to the said arms. It will be appreciated, however, that variations in the mounting structure for the inner, iixedly and pivotally mounted ends `of the arms may be provided in accordance with the invention.
The arms 36 and 38 are secured in laterally proximately spaced relation on one side of the frame A24, depending upon the convenience to the user, and the bosses 40 `and l42 have shoulders 56 and 58 formed integrally therewith -for engagement with the rear wall of the groove structure 44 so as yto limit outward pivotal movement of the arms to the position shown in dot and dash in FIG- URE 2 and in solid lines in FIGURE 3. 'In order to accommodate the arm 38 adjacent the openings for the door 22, however, the inner arm 36 may have `the shoulder portion 56 thereof formed so as to extend outwardly beyond the boss 40 therefor; and may be directly secured to the shoulder portion to overlie the outer arm 38 when the door is closed, as shown. The outer or free ends of the arms 36 and 38 likewise carry bosses 60 and 62 which are pivotally secured by pivot pins 64 and 66 or the like in a carriage 68 having a relatively elongated dimension and slidably received in a track 70 as hereinafter described. The arms 36 and 38 are connected to their outer bosses 60 `and 62 by shoulders 72 and 74 similar to the shoulders at the inner ends of the arms, but extending outwardly from the bosses in right angular relation to the arms a relatively great distance in order to afford coaction with the track means and to permit the interfitting relation between the respective arms as also seen in FIG- URE 2. In this construction, therefore, the shoulder 74 on the arm 38 extends outwardly a greater distance than the shoulder 72 for the arm 36.
The track 70 is formed with a C-shaped configuration in a preferred embodiment thereof, and has upper and lower vertical flanges 76 and 78 and integral inwardly extending lip flanges 80 and 82 spaced vertically so as to accommodate the respective arms 36 and 38 and their shoulder portions 72 and 74. iThus, the track 70 affords means for maintaining the arms 36 and 38 in predetermined outwardly extending angular relation Ito the track during slidable movement thereof and for preventing such movement until the said predetermined angular position of the arms is obtained, similar to the means in my said copending application.
The upper lip flange 80 of the track 70 has a cutout recess 84 for receiving the boss 60 of the arm 36 in the closed position of the door shown in FIGURE 2, while the lower lip 82 has a cutout recess 86 for receiving the boss 62 of the arm 38 in the said closed position of the door. The recesses 84 and 86 ltherefore permit pivotal movement of the arms 36 and 38 from the position of FIGURE 2 shown in solid line, to the position sho-wn in dot and dash, until the shoulders 56 and 58 at the inner ends of the arms abut the rear wall 88 of the groove 44. At such time, the door structure 22 is in position for slidable movement parallel to its initial position; and for this purpose, the boss 6l) of the arm 36 defines a semicircular recess 9i) for receiving the lip 80, at the upper portion of the track 70, while the 4boss 62 defines a semicircular recess 92 for receiving the lip 82 at the lower portion of the track 70. Consequently, when the arms are `in the position of FIGURE 2 shown in dot and dash, the recesses 90 and 92 will permit the arms to move slidably along the lip flanges 80 and 82, and -it will be seen that the double lip flange construction prevents interference with the movement of the bosses along the track which might otherwise be afforded if the cutout portions 84 and 86 were formed in a single lip flange. Additionally, an exceptionally high degree of stability is provided also. However, it will be appreciated that single lip flange constructions are within the scope of the invention, since each of the arms is effective to maintain the angular position of the other during travel along the track.
In the construction shown, each of the bosses 60 and 62 has the end thereof opposite the end in which its recess is formed provided with a substantially cylindrical reduced extension, these extensions being designated by reference numeral 94 with respect to the boss 60 and reference numeral 96 with respect to the boss 62 as seen in FIG- URES 4 and 5. Accordingly, the reduced cylindrical extensions 94 and 96 can pass freely along the respective flanges 80 and 82 when the arms are in the outward angular position for travel along the track, while the flanges will prevent pivotal movement of the bosses except when the bosses are aligned with the cutout portions 84 and 86. At such time, the extensions 94 and 96 will offer no resistance to pivotal movement of the arms despite the absence of further cutouts in the flanges 80 and 82 which might be in registration with the cutouts 86 and 84 respectively.
Desirably, the track 70 is formed in the door structure 22 substantially as descri-bed in my said copending application, to permit movement of the carriage 68 from its initial position as shown in FIGURE 2 substantially to the end of the door structure 22 opposite the end in which the carriage is initially positioned. However, as a result of the elongated construction of the carriage, which preferably extends slightly beyond the boss 6i! and substantially beyond the boss 62 to further stabilize the mounting for the door, the track may have a greater length to afford the fullest extent of movement for the carriage. Preferably, end stop portions 98 and 100 are provided at opposite ends of 4the track, and the track itself coacts with the carriage to afford slidable movement of the carriage by means of sets of rollers 102 and 104 respectively also as set forth in the said copending application.
Thus, it will be seen that the single carriage 68 for the respective arms 36 and 38 is entirely adequate to afford pivotal and slidable movement of the door between open and closed positions thereof without the need for auxiliary support means at the right hand side of the door structure.
Referring now lto FIGURE 6, a second embodiment of the invention is shown wherein similar reference numerals refer to similar parts, and the arms 36a and 38a are angularly formed so as to permit the bosses 68a and 62a to be suitably received within the track 70 to accommodate closing of the door, as shown in solid line, while permitting the door to be displaced laterally with respect to the door opening as shown in dot and dash to a somewhat greater extent than in the preceding embodiment. Thus, the bosses 68a and 62a may be formed without shoulders, and the shoulders 56a and 58a on the bosses 40a and 42a at the inner ends of the arms will terminate outward angular movement thereof and place the door in readiness for slidable movement, the double connection between the carriage 68 and the door frame 24 serving to hold the door in parallel to its initial position dur-ing such slidable movement. Desirably, of course, the bracket structure 28a will be elongated in comparison with the structure 28 to accommodate the 'angular configuration of the arms 36a and 38a. It will be appreciated that although the shoulders 60 and 62 of the embodiment of FIGURES l through 5 might be dispensed with similarly, the linear formation of the arms 36 and 38 makes such shoulders desirable.
The operation of the embodiment of FIGURE 6 is thus substantially the same as that of `FIGURES l through 5, and when the arms 36a and 38a are in the position shown in dot and dash in FIGURE 6, the recessed portions 98a and 92a in the bosses 60a and 62a will fit in complementary mating relationship with the flange structures and 82 of the track 70 and permit the aforementioned slidable movement of the door structure relative to the frame without interference from the lip flanges, once the bosses have turned in the flange cutouts 84 and 86 from closed position to the predetermined angular position determined for affording such slidable movement.
Referring now to FIGURES 7 and 8, the door mounting of the invention is shown in conjunction with a vehicle 108 having doors 110 and 112 mounted in a door opening 113 so that their inner edges are in abutting relation in the closed position thereof, but which permit the entire Opening to be utilized in the opened position thereof as seen in FIGURE 8. Thus, the doors 108 and 110 are desirably provided with upper tracks 114 and 116 respectively adapted for use with single door mounting arms in accordance with the invention, as designated by reference numeral 118 in FIGURE 8; and are provided with a pair of door mounting arms for use with lower tracks 120 and 122 which are designated by reference numerals 124 and 126. The tracks 128 and 122 at the bottom of the doors are substantially as described in the preceding embodiments. The arms 118 for the upper tracks 114 and 116 are fixedly and pivotally connected to the door frame or jamb 128 by a boss 130, while the outer end boss 132 thereof may be pivotally engaged in a suitable carriage structure as described with respect to my said copending application for slidable movement along a l-ip or flange in the tracks (not shown), which may be cut away to permit pivotal movement of the boss. The inner bosses 134 and 136 on the lower arms 124 and 126 are suitably mounted for pivotal movement relative to the frame, and the outer bosses 138 and 140 thereof are recessed for cooperative slidable movement with respect to a double lip flange structure (not shown) in the tracks 120 and 122 and are pivotally secured in a relatively elongated carriage therein also as hereinafter set forth.
It will be seen that the door mounting `of FIGURES 7 and 8 thus affords unusual ease of entry and exit with respect to a vehicle such as the sedan 108, as well as reducing the amount of space required for opening and closing the doors. Additionally, the fact that the mountings may be positioned in a suitable location at the sides of the door opening permits doors of less than full height to be used; and installation is markedly simpler than with previously available constructions.
The double door structure of FIGURE 1 provides similar advantages in permitting the door opening to be utilized to the fullest extent, as stated, and thus is exceptionally desirable for hospitals and the like, since beds and other equipment can be moved through the opening without interference of the type produced by the traditional sliding doors, or swinging doors.
Although I have herein set forth and described my invention with respect to certain specific principles and details thereof, it will be understood by those skilled in the art that these may be varied without departing from the spirit and scope of the invention as set forth in the hereunto appended claims.
