    摘要： A lock for the runners, particularly for runners of sliding glass doors on a display case which comprises a box-like housing including at the front sliding glass doors. A locking bolt is displaceable in axial direction and is adapted to enter into a bolt opening of another overlapping, opposing runner. A locking cylinder is operatively connected with the locking bolt, and a device is arranged for moving the locking bolt from its advanced bolt engagement position into its open position independently of the locking cylinder.The present invention relates to a lock for runners, particularly those of sliding glass doors or showcase windows, having a locking bolt on a first runner which can be displaced in axial direction and which engages in a bolt opening of another overlapping mating runner and with which a lock cylinder is coordinated.The one known lock for runners, a lock cylinder and a locking bolt are arranged parallel to one another in a common housing. The latter is fastened to one runner. In the open position of the lock, either with the key engaged in the lock cylinder or removed from it, the locking bolt releases the other runner. From this position the locking bolt can be pressed inwardly by hand in the bolt engagement direction, into a position in which the bolt is locked. The release of the locking bolt can be effected by the key which fits the lock cylinder. This construction has various disadvantages in use. During daytime operation with super vision of the display cases available in a store or office, if the locking bolt is in the locked position, the required key must always be sought out in order to release the locking bolt by means of the lock cylinder. However, if the locking bolt were left continuously in its open position, this could permit possible theft of the articles stored within the showcase even with supervision, since the open position of the locking bolt is obvious. This known development also permits possible misuse by, for instance pressing, the locking bolt without authorization, inwards.It is one object of the present invention, to provide a lock of a construction which is advantageous in use and designed so that the locking bolt has two bolted positions, namely locked-bolted and apparently locked-bolted, in addition to an unbolted position.It is another object of the present invention, to provide an improved lock for runners, particularly runners of sliding glass doors, on display window cases, which includes a locking bolt which is displaceable in axial direction and enters into a bolt opening of another overlapping, opposing runner, and has a locking cylinder operatively connected with the locking bolt. Means are also provided for moving the locking bolt from its advanced bolt engagement position into its open position independently of the locking cylinder.As a result of this development, a lock of this type which is of a construction which is advantageous in use is created. The lock in accordance with the present invention is characterized by three positions of closing (engaged-locked, engaged-unlocked and disengaged). These provide on the one hand the closed or truly locked position (truly locked-bolted), the "apparently bolted" position (apparently locked-bolted), and the open position of the lock. The locking bolt can only be brought out of the closed engaged-locked position (truly locked-bolted) of the lock when the locking bolt is released by means of the key corresponding to the lock cylinder. However, the locking bolt then still remains in an engaged-unlocked position (apparently locked-bolted). To be sure, it is only an "apparently bolted" position. This cannot be recognized from the outside. Only the sales personnel can know that the device is in an unlocked position. In this way it is possible for them to bring the locking bolt, without the use of a key, from this engaged-unlocked or "apparently bolted" (apparently locked-bolted) position into the open position by a simple manipulation. The open or disengaged position is then visible. This provides assurance to a great extent that after the sliding glass doors have been moved together, the sales personnel will not forget to bring the lock into the "apparently locked-bolted" position or the truly locked-bolted position. The parts for the construction of the present invention are simple. They are also trouble-free. The radially protruding lug of the locking bolt fulfills a multiple function: on the one hand it serves as stop for the axial movement of the locking bolt in the direction of release. On the other hand it secures the locking bolt against rotation in its released position. This has the advantage, that when the sliding doors are pushed closed, the stop for the locking bolt can enter unimpeded into the bolt opening corresponding to it. Furthermore, this locking lug secures the "apparently locked bolted" position, in which it rests against the bottom plate of the housing. In addition to this, the locking lug also serves as a stop for the rotation of the locking bolt in cooperation with the locking slide which is actuatable by the lock cylinder. The idle stroke, or lost motion which is provided in the eccentric drive, permits a favorable construction of the lock cylinder with only one position of withdrawal for the key. With the key removed, it can therefore not be noted in the "apparently locked-bolted" position of the lock what position the locking cylinder is in. The possibility of pushing the locking bolt into its "apparently locked bolted" position serves further the purpose of securing the lock. In order to be able to turn the locking bolt at all in this position, it must be pressed inwards by a certain amount. Only after this step can the locking bolt be turned. This fact further impedes unauthorized tampering.

    摘要： 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.

    摘要： A lock for sliding doors has a bolt carried by a plunger on one door and has a cross head movable into a strike on the passing door. The bolt is rotatable by a key operated core in the plunger, between two orientations. In unlocked, key-retaining orientation, the bolt is movable axially to carry its cross head from a retracted position behind the faceplate of its mounting to a projected position behind a strike on the opposite door, the face plate and strike having shaped openings to pass the cross head in that orientation. In locked, key-releasing orientation, the cross head is out of registry with the shaped openings and when engaged in the strike, prevents withdrawal of the bolt by forced separation of the doors. A spline groove and flatted sides on the bolt interengage with a shaped opening in the face plate to prevent bolt rotation at intermediate axial positions, and prevent bolt movement from end positions except after deliberate key rotation, which increases security and avoids inadvertent movement or disposition of the bolt to mar the passing door.
