HTTOFNE X United States Patent 015 Patented Aug. 9, 1960 RETAINING A LOCK CYLINDER IN A PANEL Filed May '31, 1957, Ser. No. 662,849

6 Claims. (Cl. 70-370) MEANS FOR This invention relates to locks and more particularly to means for retaining a lock cylinder in assembled position on a panel such as a drawer front, cabinet door or other like member.

An object of the present invention is to provide improved means for quickly mounting a lock cylinder and securely retaining it in mounted position.

A further object is the provision of an improved retaining clip for such locks.

A.still further object of this invention is the provision of improved means for securing the retaining clip to a lock cylinder in such a manner that it will not become accidentally detached therefrom.

Further objects and advantages of the present invention will be more clearly understood from the following description and the accompanying drawings in which:

Fig. l is a plan view of a lock cylinder and a retaining clip constructed in accordance with this invention and showing same in assembled position.

Fig. 2 is an end view with portions in section on line 2-2 of Fig. 1.

Fig. 3 is an elevational view of the lock shown in Fig. 1.

Fig. 4 is a similar view with the retaining clip shown in section on line 4-4 of Fig. 1.

In the embodiment illustrated in the drawing, the numeral 5 denotes a lock cylinder body of conventional form having a head 6 which provides an annular flange 7 around said cylinder, and the numeral, 8 denotes a lock bolt which is slidable in said cylinder and is operated by a key plug, not shown, that is rotatably mounted therein.

The said lock cylinder is adapted to be installed in a panel member 9 which may be a drawer front, a cabinet door or other like member. It is preferably provided with flats 10-10 at its opposite sides and extends through a hole 11 in the member 9 which is of corresponding shape whereby rotation of the said cylinder is prevented.

In accordance with the present invention, opposed slots 12-12 are formed in the periphery of the cylinder 5 adjacent the flange 7, said slots being angularly disposed ninety degrees from the flats 10-10. The bottoms ofthe said slots are formed with radially extending projections 13-13 for a purpose hereinafter described.

In order to retain the said lock cylinder in position, my invention further provides a retaining clip 14 which is preferably stamped from sheet metal and heat-treated to render it resilient. The clip includes spaced leg portions 15-15, extending from a connecting portion 16, and a grip portion 17 that extends perpendicularly from and stitfens the connecting portion 16. The said leg portions 15-15 are preferably curved, as shown in Fig. 1, to provide raised central portions 18-18 and foot portions 19-19 which lie substantially in the plane of the connecting portion 16. The inner edges of the said leg portions 15-15 are provided with notches 20-20 which receive the projections 13-13 and thereby secure the retaining clip to the lock cylinder.

A positioning finger 21 extends from the connecting portion 16 to engage the lock cylinder and thereby locate the clip in proper position with relation to the lock cylinder and also prevent forcing of the clip beyond the position in which the projections 13-13 are in register with the notches 20-20.

The said retaining clip is so made that when it is forced into the position shown in Fig. 1, it is deformed and there fore applies a spring force against the inner sides of the slots 12-12 which biases the lock cylinder inwardly in the member 9 and forces the flange 7 against the outer surface of said member. The lock cylinder is thus securely retained in assembled position relatively to the said member 9.

If the lock cylinder were permitted to move outwardly relatively to the member 9, such as would occur if the drawer or door upon which it is carried was forcibly closed with the bolt 8 in locking position, the legs of the retaining clip might possibly be permmently bent and looseness of the lock cylinder would result. In order to prevent such outward movement of the lock cylinder, the leg portions 15-15 are provided with flanges 22-22 that are bent perpendicularly therefrom and terminate adjacent the inner surface of the member 9 so as to proinvention, the cylinder 5 is first inserted through the hole ll until the flange 7 is brought into contact with the outer surface of the member 9. The leg portions 15-15 of the retaining clip are then inserted into the slots 12-12 and the said clip is pushed over the cylinder until the finger 21 strikes said cylinder, at which time the projections 13 are in register with the notches 20-20 and the leg portions will spring inwardly into engagement with the said projections.

It will be noted that the inner edges of the lower portions of the leg members are tapered outwardly and downwardly so that they will slide over the projections 13 and cause the said leg members to spread as the clip is being pushed into position.

I claim:

l. A look structure including in combination a lock cylinder having a body portion insertahle through an opening in a panel member and a flange on said body portion engageable with the outer surface of said panel member for locating the lock cylinder thereon, the said body portion having slots in its opposite sides with inner edges facing said flange and spaced therefrom a distance greater than the thickness of said panel member, a resilient retaining clip for securing said lock cylinder to said panel member, said clip having spaced legs insertable through said slots and engageable with the inner surface of said panel member at opposite sides of said lock cylinder, the intermediate portions of said legs being bowed inwardly and adapted to press against the said inner edges of the slots whereby force is exerted inwardly on said lock cylinder to retain it in proper position, and abutments extending outwardly from the intermediate portions of said legs and engageable with the inner surface of said panel member to prevent excessive outward bending of said legs upon the application of an outwardly directed force to said lock cylinder.

2. The subject matter set forth in claim 1 wherein said abutments comprise flanges extending perpendicularly from the outside edges of the intermediate portions of said legs.
