7 Claims. 1
This invention relates to building hardware, and in particular, to push-pull bars for doors.
One object of this invention is to provide a push-pull bar construction for attachment to the opposite sides of the door in such a manner that the attachment devices are concealed from view in an opaque door and show only two screws at the meeting ends of the bars in a transparent door.
Another object is to provide a blind attachment construction for push-pull bars for doors of either opaque or transparent construction, wherein the usual screw plates are eliminated and the only visible evidence of attachment in a door with an opaque door frame is the countersunk head of a single screw at each end of one of the push bars, even this screw head being visible only by looking up at the bar from beneath it.
Another object is to provide a blind attachment construction for push-pull bars for doors of either opaque or transparent construction wherein one of the bars is secured to the door frame by a pair of concealed screws at either end, and the other bar has its ends secured to the opposite side of the door frame by being attached to blocks held by the same pair of screws which hold the opposite push bar against the opposite side of the door.
. Another object is to provide a blind attachment their heads seated in sockets in the blocks and secured therein by a single screw passing upward from beneath the block through Athe heads o1' both studs, thereby resulting in a completely concealed connection for opaque door frames when the push bars are viewed from any direction except upward from below one of the push bars.
In the drawings:
Figure 1 is -a horizontal section through a door with an opaque door frame taken along the line l-I in Figure 4 and showing the push-pull bar construction of the present invention in top plan view, partly in horizontal section at the ends of the bars; l
Figure 2 is a vertical longitudinal section along the line 2-2 in Figure 1;
Figure 3 is a vertical cross-section line 3-3 in Figure 1; and
Figure 4 is a reduced perspective view of a door equipped with the push-pull bar construction of Figures 1 to 3 inclusive.
along the SEIS Doors of commercial and residential buildings are frequently equipped with so-called pushpull bars for assisting persons to open and close the door by applying pressure to the bars in the appropriate direction. Such bars are frequently used on swinging doors so that the door may be opened from either direction by pushing or pulling the push bar on that side of the door. In the past, it has often been the practice to secure the ends of suchvpush bars to the door by means of screw plates mounted on the opposite sides of the door. Such screw plates, however, are not only very visible but also are unsatisfactory for use with glass doors or doors with tubular metal frames which have very narrow stiles or backing plates. With transparent doors, moreover, such as are frequently found in modern stores, apartment buildings or the like, these prior attachment arrangements are ugly in appearance in contrast to the beauty and modernity of appearance of a completely transparent door having no door frame.
The push-pull bar construction of the present invention'eliminates the disadvantages of these prior doors by securing each end of one of the push bars to the door or door frame by a pair of connecting screws threaded into the end from the opposite side of the door through a block having sockets which receive thel heads of locating studs threaded into the adjacent end of the other push bar. The heads of the locating studs, in turn, are held in these sockets by `a single anchoring screw passing upward through the head of the lower stud and threaded into the head of the upper stud. In this manner, only the head of a single screw is visible at each end of one only of the push bars, and even this screw head is countersunk into the bottom of the block and can be seen only by stooping so as to look up at the push bar from below.
Moreover, in the present invention, there is no need for the attachment plates or backing plates hitherto required, and the Stiles of the door frame can be as narrow as desired, or may be omitted altogether, as in transparent frameless doors. In addition to the single anchoring screw at each end beneath one of the push barsy the only visible evidence of attachment, even in a transparent door, is the pair of screws passing through the door into each end of the other push bar. Thus, the number cf parts in the present invention is not only reduced to a minimum but these parts are for the most part concealed from view. The nished push-pull bar construction, moreover, is of clean, modern-appearing design with no pro- 3 jectlng parts or separate attachment members to mar the beauty of its appearance.
Referring to the drawings in detail, Figures l and 4 show a conventional door, generally designated I0, equipped with a push bar assembly, generally designated I I which in turn includes push bars I2 and I3 and attachment blocks I4. The door IIJ may be ofany conventional construction, that shown having wood Stiles or upright frame members I5 interconnected by horizontal members I6 and I1 at top and bottom re- Y spectiv-ely, these enclosing a glass central panel I8. This construction, however, may optionally be partly or wholly metallic, or the door may consist throughout of a single panel of transparent material such as glass, without any stiles whatever. The details of the door form no part of the present invention.
The push bars I2 and I3 have elongated central portions I9 and 2D in their opposite ends 2l and 22 bent into parallelism. The ends 2l are longer than the ends 22 (Figure 1) by the lengths of the blocks I4 so that the appearances of the push bar assemblies on opposite sides of the door will be substantially the same. The ends 2l of the push bar I9 are bored and threaded as at 23 to receive the threaded ends of attachment screws 24 passing through boresl 25 in the stil-es I5. A pair of screws 24, one above the other, is preferably used at each end of the push bar i9, and the Shanks of these screws pass through bores 26 in each block I4. The bores 26 open into counterbores or sockets 21 which receive the heads of the screws 24. The opposite ends 22 of the push bar 22 are bored and threaded as at 28 to receive the threaded portions of locating studs 29, the heads 3i) of which are received in the sockets or counterbores 21 (Figure 2). The heads 3B are provided With bores 3I aligned with a bore 32 passing upward through the block I4 from a counterbore 33. The counterborer 33 receives the head of an anchoring screw 34, the shank of which passes through the lower bore'3'I and is threaded into the upper bore 3I so as to secure the assembly together.-
In attaching the push bar assembly II to th-e door I6, lthe .latter is provided with verticallyspaced pairs of holes 25 at the desired level above the floor,.and spaced to correspond with the threaded bores 23. The connectingscrews 24 are then inserted in the sockets 21 with their shanks passing through the bores 26 and through the holes V2,5v in the door stiles I5, after which they are threaded into theV threaded holes 23'. When the attachment blocks I4 have. thus been secured firmly to one side of the stile I5 and the push bar I2 to the other side, the studs 29 are threadedinto their threaded sockets or holes 28 and' turned until their transverse bores 3l are in alignment. They are then inserted in the sockets or counterbores 21 by pushing the ends 22 of the push bar 29 rmly against the blocks I4. While the parts are held in' this position, the anchoring screws 34 are inserted from below into the counterbores 33, passed through the lower stud bore 3| and the attachment block bore 32 and threaded into the upper stud bore Si. When the anchoring screws 34 are tightened, their heads enter the counterbores 33 and accordingly become concealed therein.
In this manner, the push bars I9 and 25J are connected to the door I with a virtually invisible connection. If, however, it is desired to detach the push bars, this may be done by reversing the procedure just described. In disassembling the push bar assembly II, therefore, the anchoring screws 34 are first removed, thereby permitting the push bar and its studs 29 to be Withdrawn from the sockets 21 in the attachment blocks I4. This exposes the heads of the connecting screws 24 so that they may be removed by the use of a screw driver inserted in the sockets 21. The removal of the connecting screws 24 Vfrom the threaded bores V23'and therstile bores 25 releases the push bar I9 on one side of the door and permits the attachment blocks I4 to be detached from the other side of the door.
The concealed push bar construction of the present invention may also be used with certain types of swinging doors when the inner end of the push bar is bent toward the door and closely into parallelism withthe door so as to avoid collision with the door frame when the door is swung to and fro. The outer ends of such push bars may employ the construction of the present invention as shown in thevdrawings and as described above.
