2 Claims.
for closures. and is primarily concerned with a novel casing insert, and especially an insert having lock operating parts secured thereto so as to form a. unit assembly.
It is one object of the present invention to provide a novel lock structure, wherein certain parts are preassembled as a unit and arranged to be releasably mounted on the lock casing to accommodate the lock for specific installation requirements.
A further object of the herein described invention is to provide a lock arrangement of simple, unique construction in which certain parts are readily interchangeable; thus providing a high degree of flexibility of mounting and operation under varied conditions of installation. I
A still further obiect is to provide an improved article of manufacture in the form of a novel lock casing insert with associated mean for releasably securing it in mounted position.
Further objects of the invention will be brought out in the following. part of the. specification wherein detailed description is for the purpose of fully disclosing the invention without placing limitations thereon.
Referring to the accompanying. drawings, which are for illustrative purposes only: I
Fig. l. is an elevational view of one face of a lock mechanism embodying the features. of the present invention, an associated. door and door jamb being shown in dashed lines Fig. 2 is an elevational view of the lock,. as seen from its opposite face Fig. 3 is an enlarged fragmentary partial section, taken substantially on line 33 of Fig. 1;
Fig. 4 is an enlarged sectional view, taken substantially on line 4ls of Fig. 3.;
Fig. 5 is a similar sectional view, taken substantially online 5-5 of Fig. 3; and- Figs. 6 and '7 respectively illustrate modified insert constructions embodying the present invention.
Referring more specifically to Figs. 1 and 2 of the drawings, the present invention is embodied in a lock enclosing casing as generally indicated at A, and which is mounted upon a sliding door panel Ill as indicated by dashed lines for cooperative association with a door J'amb lit, as indicated in dashed lines, uponwhich a projecting keeper i2 is' supported.
The lock casing A comprises generally a pair of spaced side walls l3 and M between which there is housed a locking mechanism such as de- 2v scribed in the copending application of Arthur R. Adams. et al., Serial No. 23,426, relating to a Slidi'ng Door Lock Mechanism.
It is not deemed necessary in the present application to describe all the details of the lock mechanism of the. copending application. It is thought that it will be sufficient to merely state that such lock mechanism includes a pivotally mounted lock member it, as shown in dotted lines in Fig. 1,. which is adapted to be actuated to locked. position by engagement with the keeper l2 when the door is closed. Closing of the door causes a hook shaped end is. of the lock memher to engage the keeper [2, mechanism (not shown) being provided for latching the locked member in locked position against a spring acting to bias the locked member towardopen position.
Control of the latch member is accomplished through manually operable. actuator members I! and M." respectively mounted for sliding movement in an associated recess l8 and i8 respectively formed in the casing side walls.
There is cooperatively associated with the member for latching the lock member it against opening movement, a swingably mounted locking bar It which is supported upon a frame structure 2.8 of. the lock mechanism on a suitable pivot 21'. As clearly disclosed" in Fig. 3, the upper end oftliev locking bar l9 terminate in a transversely extending headpiece 22 so as to form with the locking bariii a generally T-shaped; member. The headpiece 22, it will be observed, projects beyond the frame structure 20 and extends substantiallybetween the side walls It and M- Above the recesses l8 and [8 the side walls are provided with generally circular shaped recesses 2'3 23", respectively, of similar constmction. Each of these recesses has a bottom opening it, the openings of the. respective recesses 25 and 23" being axially aligned. The bot.- tcm opening is, in each case, defined by a pcripheral flange which has parallel vertically disposed inner edges 25 audit, a shown in Fig. 1.
3 a key-cylinder assembly 29 containing a seating head 30 and a barrel portion 3|. The key-cylinder assembly in its threaded .portion is shaped to conform with the inner edges 25, 26, 21' and 28 of the recess bottom flange, and is retained in place by means of a ring nut 32.
The key-cylinder assembly includes a conventional actuating cam arm 33 which may be rotated in one direction to operatively shift the headpiece 22 in one direction, and in the opposite direction to shift the headpiece in a reverse direction, so that the locking bar may thereby be activated to locked and unlocked positions.
In addition to the key-cylinder assembly 29, there is also provided a preassembled insert as generally indicated at 34. This insert may assume several difierent forms of construction depending upon the particular operating requirements of a specific installation.
In the specific insert assembly shown in Figs. 1, 3, and 4, there is provided a disc-like member having a flanged head portion 35 adapted to seat in a recess 23 or 23', this head portion having a projecting portion 36 extending from its rear face and peripherally shaped to fittingly conform with the edges 25, 26, 21 and 28 of the recess opening.
As shown in Fig. 1, the disc-like member is provided with a transversely extending elongate slot 31 which is arranged to have its longitudinal axis extend at right angles to the parallel edges 25 and 26, when positioned in the associated recess. A digitally engageable button 38 is mounted for movement over the outer surface of the head portion 35, this button having a rearwardly projecting stem 39 which extends through the slot 31 and is laterally shiftable therein. The innermost end of the stem 39 connects with the head portion of a generally T-shaped member 40. The head portion of the member 40 forms oppositely projecting wings 4i and 42 which substantially maintain the slot 37 covered on its inner side during shifting movements of the button 38. The stem portion 43 of the member 40 is deflected at its lowermost end and deformed to provide a downwardly openinggroove 44 which is adapted to fit over and receive therein a portion of the headpiece 22 in the manner clearly shown in Figs. 3 and 4.
The disc-like member is preassembled with the button 38 and connected T-shaped member thereon as a unit which may be mounted in one of the recesses where desired to provide for digital control of the locking bar I 9 in addition to the provision of key-cylinder control. However, the key-cylinder control may or may not be provided, or it may be provided without providing the insert assembly. Moreover, these two assemblies are interchangeable. The insert assembly is retained in mounted position in the associated side wall recess by means of a generally U-shaped retaining member 45 having spaced legs 46 and 41 which may be moved endwise to dispose their inner edge margins 48 and 49 respectively in parallel surface grooves 56 and which are spaced from the flanged head portion 35 sufficiently to let the retaining member 45 lie along the inner face of the recess bottom flange. The legs 46 and 41 are given a certain amount of lateral resiliency by providing reduced portions 52 and 53 by cutting away the inner corners at their junction with the crosspiece of the member. The retaining member is releasably latched in retaining position by providing an overhang lip 54 adjacent the free end of each leg for snapping over the adjacent end of the associated groove, so as to releasably latch the member against removal.
A slightly modified construction is disclosed in Fig. 6. In this construction, the elongate slot 31 is provided with a peripheral edge groove 55 which defines a seating flange 56 for the button 38'. The button in this case is of such thickness that its outer surface will be substantially flush with the outer surface of the head portion 35, and is provided with a central opening 51 adapted to receive the end of a pointed member for emergency movement of the button 38 to throw the headpiece 22 in the desired direction.
In its simplest form, as shown in Fig. 7, the insert merely forms a blank which is placed in the recess 23 or 23' so as to close the opening in the side wall, when it is not desired to provide one of the manual operating assemblies.
It will be appreciated that, while the invention has in general been described as being applied to a sliding door lock structure, the invention is susceptible of general application to lock structures, and it is not intended that it shall be specifically limited to sliding door locks only.
I claim:
1. In a lock: a casing side wall having a recessed opening therein; an insert having an elongate transversely extending slot, one end of said insert being adapted to seat within said recess in substantially flush relation with respect to the outer surface of said side wall, and its other end being adapted to project through said wall opening; a retaining member on the inner side of said wall engageable with the projecting end of said insert; a member having angularly extending legs, one of said legs being grooved to receive an associated lock member therein, and the other of said legs having a projection extending into and movable in said slot.
2. An article of manufacture for mounting on a plate having an opening defined by opposed straight side edges and arcuate end edges connecting the ends of said side edges, comprising: a disc-like member having an elongate slot therein, said member being formed with a flanged head portion and a reduced projecting portion adapted to be inserted into said opening, said projecting portion having parallel sides and armate ends, and corresponding in cross section to the shape of said opening, and diametrically opposed surface grooves in said ends; a connecting element disposed adjacent the face of said reduced portion; a member longitudinally movable in said slot having a connection with said element; and means engaging said grooves for releasably connecting said member to the plate.
