24 Claims.

the lock structure per se, including removably' securing the cylinder in place, is eifected in a simple and eflicient manner.

Another object of this invention is to provide a lock of the character described wherein the locking bolt is utilized to removably secure the lock cylinder in place.

Another object of this invention resides in the provision of a lock of the character described having a single anti-rattle spring which eifectually takes up all play between the component parts of the lock and also serves to firmly hold the door-closed.

Another object-of this invention resides in the provision of a lock of the character described wherein the locking bolt while lying in its normal path of movement serves to prevent rotation of the cylinder to a position at which it is removable and wherein the locking boltis movable out of its normal path of movement when in an unlocked position to enable the cylinder to be moved to an assembling and disassembling position. v!

Another object of this invention resides in the provision of means to positively hold the locking bolt in its proper path of movement except when the bolt is moved to its fullyunlocked position. Another. object of this invention is to utilize the anti-rattle spring toyieldingly hold the locking bolt in its proper path of movement. Another object of this invention resides in the novel manner in which the locking bolt and the anti-rattle spring are assembled with the lock housing or body and cylinder sothat these units are retained in their proper-relative positions upon assembly entirely without the aid of securing as hereinafter described-and more particularly.

defined by theappended claims, it being understood that such changes in the precise embodiment of the hereindisclosed invention may be made as come within the scope of the claims.

The accompanying drawings illustrate one coniplete example of the physical embodiment of the invention constructed according to the best mode principles thereof, and in which:

Figure 1 is a view through a. portion of a compartment door and its frame illustrating the application of this invention thereto, a part of the lock being in section and part in elevation;-

Figure 2 is a rear view of the structure with parts broken away and in section, said view being taken on the plane of the line 2-2 of Figure 1;

Figure 3 is a view similar to Figure 1 showing the locking bolt retracted to its unlocked position;

Figure 4 is a cross section view taken through Figure 3 on the plane of the line 4-4;

Figure 5 is a cross section view taken through Figure'3 on the'plane of the line 5-5;

Figure 6 is a view similar to Figure 3 showing the manner in which the locking bolt is actuated to permit movement of the lock cylinder to its 'positio'nof removal; 1 Figure '7is a section view taken through Figso far devised for the practical application of the ure 6 on the plane of the line 1-1;

panying drawings in which like numerals indicate like parts throughout the several views, the numeral 5 designates a door which may be the door of a glove compartment with which the in-; strument panel of automobiles is now generally equipped.

The door is hinged in any suitablemanner and when closed its outer freeedge portion abuts a rubber bumper 6 carried by the adjacent part of the frame. I which surrounds the periphery of the opening closed by the door. 7

A springcatch 8 is carried by the door to snap over the inner edge 9 of the frame 1 to hold the door closed when it is not desired to lock the same. The particular spring catch shown comprises a spring arm lll' bent rearwardly from an attachins flange l-I rigidly secured to the inner face of .the door, preferably-by being clamped between the dooran'd a nut IL, which also serves to hold the locking. unit, indicated generally by the numeral iii, to the door.

The locking unit i3 comprises a lock housing or body I having a generally cylindrical inner portion l5.and an outer enlarged knob portion IS. The shoulder I! at thejuncture of these two portions abuts against the outer face of the door so that the rear portion I5 of the lock housing or body projects from the rear face of the door. The part of the rear portion adjacent the shoulder I1 is threaded to receive the clamping nut 12, and to prevent relative rotation between the lock housing and door, the inner portion l5 preferably has a flat side and the hole in the door is shaped accordingly. Hence, by merely inserting the lock housing or body through the opening in the door and securing the-clamping nut l2, the lock structure and also the spring catch are firmly secured to the door in their proper relative positions.

The lock body or housing is bored to receive a lock cylinder [8. That portion of the cylinder disposed within the outer knob ii of the body or housing has a plurality of tumblers (not shown) to secure the cylinder against rotation as is customary. The tumblers are retractible by a proper key I! to free the cylinder for rotation.

Rotation of the cylinder is utilized to actuate a locking bolt 20 to and from a positionprojecting through a hole 2| in the spring catch and over the edge 9 of the door frame. When so disposed, the locking bolt securely holds the door in closed position.

The locking bolt 20 is slidable in an opening 22 extending diametrically through the inner end portion of the lock housing or body in communication with a bore 23 in which an extension 24 on the lock cylinder is disposed. An eccentric driving cam 25, preferably formed integral with'the rear extension 24 of the cylinder, extends into a transverse recess 26 in the locking bolt to actuate the same as the cylinder is turned.

Carried by the locking bolt is a bowed leaf spring 21 which, as will be hereinafter more fully described, serves to damp out rattles, not only between the door and its frame, but also between the component parts of the lock structure per se.

This spring 21 has one end 23 anchored in a notch or recess 29 in the operative end portion of the locking bolt. The disposition of the notch or recess 29 and the shape of the spring 21 when free is such that the spring will be compressed when the bolt is in position. i It will be noted that the bowed medial portion of the spring slides in a groove 30 formed as a rearward extension of the transverse opening 22. In this manner sidewise relative motion between the bolt and spring is efiectually prevented so that the spring and bolt are held assembled upon assembly of these parts with the lock housing or wardly of the inner edge 33 of the transverse opening 22 so that the cylinder is'yieldably urged outwardly of the lock housing or body l4. tendency to push the cylinder out of its bore is opposed by the engagement of an annular flange 34 with an abutment 35 projecting inwardly from the wall of the bore 23. l

The annular flange 34 has a gateway 36 which,

, when aligned with the lock or abutment 35, permits endwise removal of the lock cylinder. Such alignment of the gateway 33 with the lug or abutment 35, however, requires rotation of the lock cylinder beyond one of its normal limits which is normally prevented through coaction of the locking bolt and the eccentric driver 25, as now about to be described.

As clearly illustrated in Figures 1 and 2, the innermost end of the eccentric driving cam lies closely adjacent the bottom of the recess 26 so as to abut a wall 38 at one end of the recess 26 in the unlocked position of the cylinder and bolt as shown in Figure 4. In this position of rotation the gateway 36 is not aligned with the lug or abutment 35, and consequently, removal of the cylinder is impossible. In the opposite or locked position of the bolt and cylinder, removal of the cylinder is also prevented as the gateway 36 is then likewise out of alignment with the lug or abutment 25.

Upon rearward depression oi. the tail end of the locking bolt, as illustrated in Figure 6, however, the wall 38 is moved rearwardly of the driving cam 25 so that the barrier it formed against further rotation of the cylinder (in a counterclockwise direction as viewed in Figures 4 and '1) is removed allowing the rotation of the cylinder to be continued in said counter-clockwise direction beyond its normal limit to a point at which the eccentric cam 25 engages a fixed abutment 33 formed as an integral part of the lock housing or body, as clearly shown in Figure 7.

With the cylinder in the position defined by the engagement of the cam 25 with the abutment 3!, the gateway 38 is aligned with the lug or abutment 35 so that removal of the cylinder from its mounting member or housing is permitted.

To positively preclude rearward displacement of the locking bolt out of its normal path of movement when in all positions except unlocked, as by the application of an outward pull on the knob when the bolt is'holding the door closed, V

two projections or pads 4|] and 4| extend from each side of the locking bolt to slide in grooves 42 in the side walls of the opening 22.

As long as both projections or pads 40 and 4| are engaged in the grooves 42, lateral motion of the locking bolt is restricted to the slight amount of play necessary for free action, but when the cylinder is turned.to its unlocked position retracting the bolt as shown in Figures 3 and 6, the pads or projections 4! are disengaged from the grooves 42 so that the bolt may be pushed rearwardly as shown in Figure 6 tden-' able rotation of the cylinder to its position allowing the same to be withdrawn from the housing. It is to be noted that the nose or operative end portion of the looking bolt has an inclined surface 45 which engages the edge 9 of the door frame as the bolt is projected to its operative position to securely draw the door closed, the bowed leaf spring 21 being compressed'as the bolt is projected to operative position. The spring 21 thus serves toprevent rattles as between the door and its frame, and by pushing the bolt against the inner end of the cylinder extension 24, it likewise takes up all play between e c omponent parts of the lock structure. From the foregoin description taken in connection with the accompanying drawings, it will be readily apparent to those skilled in the art to which this invention appertains, that this invention provides a lock particularly adaptable for securing glove compartment doors closed and one which has an advantage over past locks for this purpose by virtue of its simplified construction and ease of assembly, and freedom Irom rattles.
