LOCK RETAINER Filed July 8, 1948 i INVENTOR.

tially overlying the lock-receiving aperture I4 to provide means or edges for engaging the body I8 of the lock I6. These body engaging edges 29 and 3| are adapted to embrace the lock body I8 within recesses or

grooves

36 and 33 provided on opposite sides of the lock body I8. The arched configuration of the head provides cam surfaces along the margins 29 and 3| of the clamping head 28, these cam surfaces enabling the retainer plate 26 to draw the lock assembly axially into mounted position on the panel 26.

Along one margin of the retainer plate 26 are two laterally extending engaging ears or

tabs

32 and 34. These tabs are positioned

opposite apertures

36 and 38, respectively, which are provided in the inner panel 31 of the door unit. When engaged by a tool such as a screw driver 46, the

retainer plate 26 may be rotated to lock-receiving position (as in Figure 2), or likewise, to retaining position (as in Figure 3), as desired. By this arrangement the necessity of removing the inner panel 31 to disengage the mounting means is eliminated and mounting or dismounting of the lock structure on the panel is accomplished with great facility. Ears or

tabs

32 and 34 preferably are recessed by having a concave or angular face so that positive engagement of the surface with a tool such as screw driver 43 is assured, as seen in Figure 3. Furthermore, by forming the

tabs

32 and 34 in this manner, a stronger tab portion is provided. When the lock retainer is mounted on a vertical panel the retainer plate 26 is preferably mounted with the clamping head 28 overhanging the aperture I4. This insures retention of the lock structure in the panel by the retainer plate 26 despite vibrations and other forces which might tend to cause disengagement of the retainer member 26 from the lock body I8.

The base plate I2 is provided with

stops

42 and 44 for limiting the pivotal movement of the retainer plate 26 relative to the base plate I2. Complementary locking detents 46 and 48 are provided on the base plate I2 and retainer plate 26, respectively, to releasably hold the locking plate in lock-receiving or looking position.

In operation, the retainer plate 26 is moved to lock-receiving position, as shown in Figure 2, to .permit insertion of the lock body I8 through the apertures 22 and I4 in the outer panel and base plate, respectively. Shoulder or flange 11 of the lock body I8 engages the outer surface of the panel 26. A tool such as screw driver 40 is then inserted through aperture 36 and the retainer plate rotated about pivot 24 toward looking position. As rotation progresses, theinner margins 29 and 3| 0f the retainer plate 26 engage the shoulders provided by the recesses 36-33 in the lock body. The lock assembly is retained against rotative movement by the clamping action of the oppositely positioned engaging margins 29. and 3I of the clamping head 28 and the oppositely'positioned

grooves

30 and 33 of the lock body I8. The arched margins 29 and 3| of the clamping head 28 draw the lock structure axially to seat the flange I! of the sleeve I8 against one surface of the panel and to retain the lock structure in this position.

Figure 6 shows another form of lock retainer II'Ia contemplated by the instant invention. Lock retainer IIla comprises a base plate IZa and a retainer plate 26a pivotally mounted on the base I2a by rivet member 24a. The margin of aperture I4a of the base plate [2a is provided with a series of spaced keyways or slots 56. The base plate I2a about the periphery of the aperture 4 14a is provided with pairs of circumferentially extending arms 52 and 54 which have formed thereon portions adapted to coast with the edges of panel 26a. defining keyways 56 for securing the base plate 12a to the panel 26a. Arms 54 are hook-shaped and adapted to be hooked over a radially extending edge of keyways 56 to engage both surfaces of panel a upon rotationof the base plate relative to the panel 20a, after which the L-shaped resilient arms 52 latchingly engage the opposite radially extending wall of the keyways 56. The arm 52 is necessarily resilient to permit engagement of the hook-shaped arm 54 with the panel 23a prior to the registration of the flange 58 of the L-shaped arm 52 with the keyways 6%. Retainer plate 26a has a resilient arm 64 sheared or struck from the retainer plate.

' This resilient arm has a dimple or detent 66 which is adapted to engage a complementary portion 46a provided in the base plate I2a for holding the retainer plate in lock-receiving position. A second dimple similar to portion 46a, not seen in Figure 6, is engaged by detent 66 of the retainer plate to hold the plate in locked position relative to the base plate'l2a.

In Figure 7 is shown the base plate I2 having a plurality of

tabs

66 and 62 to engage opposite walls of keyways in the panel 23. This is a preferred form where the lock retainer is mounted or

arms

32 or 34 on the retainer plate 26 and

apertures

36 and 38 in the inner panel affords simple means for operating the look retainer structure when it is secured to the panel and eliminates the burden of gaining access to theback'structure by removal of panel sections etc.

The arching of the clamping head of the retainer 1 plate provides a very sturdy clamping head, and

at the same time provides the cam surfaces essen tialfor securing the lock against'axial movement I on the panel.

The C-shaped construction of the clamping head afiords positive locking of the fastener against rotative movement relative to the panel. The lock retainer mounting provides a unit which remains in operative position at all times, and in addition, precludes the possibility of unauthorized dislodgment of the look by vibration, tampering or jarring.

For purposes of illustration, one practical application of the retainer device has been shown,

namely, the application thereof to cylindrical or pillar locks. Obviously, the invention is not restricted to use in this particular field, but is capable of many other practical applications. It

is to be understood that thisinvention should be I limited only by the'scope of the appended claims.
