21 Claims.

This invention relates to locks and refers particularly to glove compartment locks for auto'- mobiles.

Compartments located in the dash of automobiles and commonly referred to as glove com partments are generally equipped with hinged doors. It is desirable to provide locks for these doors,.and as shown in Patent No. 2,006,922 lssued to Edward N. Jacobi, July 2, 1935, to combine the locks with a knob-like structure to facilitate opening and closing of the door.

Heretofore, a spring catch was used to-yieldingly hold the door `closed independently of the lock, the lock being usedonly'to positively secure the door in closed position. The lock was thus of the dead bolt type. In locks of this'type, if the bolt is placed in its locked position before the door is closed, the projecting bolt interferes with closing of the door and may break if the door is slammed.

The disadvantages of this construction are` manifest, and to overcome the same, this invention has as an object to provide a simple, inexpensive spring bolt type of lock, particularly applicable for glove compartments.

A further object of this invention is to provide a lock for the purpose described wherein release of the bolt is eiected by inward depression of the lock cylinder in the fashion of a push button. Another object of this invention resides in the provision of novel means for eliminating rattling in a lock of this type, and to utilize the bolt spring for this purpose.

Another object of this invenon is to provide a construction wherein part of the boit actuating mechanism is utilized to removably retain the cylinder in its casing.

A further object of this invention is to simplify the manner of attaching or mounting the lock to the door or panel with which it is used. With the above and other objects in view which will appear as the description proceeds, this invention residesv in the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly dened by the appended claims, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within 'the scope of the claims. The accompanying drawings illustrate several complete examples of the physical embodiment of the invention constructed according to the best modes so far devised for the practical application of the principles thereof. and in which: Figure 1 is a -iongitudinal section view through a lock embodying this invention its manner of use;

Figure 2 is a view similar to showing the bolt released; l

Figure 3 is an enlarged detail view similar to Figure 1 to show particularly the manner in which play is taken up between the parts to prevent rattling;

Figure 4 is a detail view taken von the plane of l the line 4-4 ot'Figurel; Figure 5 is a perspective viewoi.' the loci: cylinder; I

Figure 6 is another perspective view of the lock cylinder taken from another angle;

Figure 7 is a perspective -v-iew of the lock casing showing the inner-or rear end thereof;

Figure 8 is a'front view of the lock casing; -Figure 9 is a perspective view of the bolt;

Figure 10 is a perspective view of the pusher member; and j I Figures 11 and12 are, respectively, a detail section view through the inner end of the casing, and a perspective view'of the locking bolt to show a slightly modied embodiment of the invention.

Referring now more particularly to the accompanying drawings in which like numerals indicate like parts throughout the several views, the numeral 5 designates the door of a glove compartment, or the like, adapted to be secured in a closed position fixed with respect to a panel 6 in which the door opening is formed by means of a lock mechanism, indicated generally by the numeral 1.

The lock mechanism comprises a casing 8 bored as at 9 to receive a llock cylinder I0. The e outer end of the casing 8 has an enlarged iiange H so as to give the casing the form of a knob to facilitate opening and closing of the door. The outer or front end of the cylinder has the usual head i0' disposed within a counterbore 9. It is exposed and accessible from the front of the lock so as to permit the cylinder to be depressed linwardly in the manner of a push button when unlocked. Such inward depression of the cylinder is utilized-to releasea bolt i2 projecting from and illustrating Figure 1, but

the inner or rear end of the casing, as will be hereinafter more fully described.

The inner or rear end portion of the casing is reduced in diameter to provide a shoulder'. I3 nich abuts the outer face of the door 5 when the casing is mounted thereon with its inner end portion projecting through a hole I4 in the door. The casing is secured to the door by coniining the door between the shoulder I3 and the periphery of a retaining cup l5 telescoped over the reduced inner end of the casing and held thereto by a screw I6 threaded in a tapped hole in the casing.

The bottom wall of the retaining' cup has a transverse slot or opening II through which the bolt I2 projects to permit the same to engage a keeper member I8 fixed to the panel 6. An upturned lip I9 formed as an'integral part of the retaining cup precludes depression of the bolt by means of an implement inserted through the space between the upper edge of the door 5 and the panel 6.

The lock bolt is hooked to engage over the keeper member I8 and has an elongated outer end portion arranged to strike the keeper member I8 and permit automatic engagement of the bolt therewith. The inner end portion of the bolt is disposed in an open recess 20 in the inner end of the casing where it is loosely pivoted by a pin 2I. The width of the open recess 20 is such that the bolt is guided by the opposite fiat sides of the recess in its pivotal movement to and from operative position to which it is yieldingly urged by a spring 22 confined between the boltl and a wall 23. The wall 23 provides a bottom for the bore 9 of stepped formation with a hole therewith a gateway 2'I leading thereto.

through coextensive with the upper half of the open recess 20. To hold the spring against displacement the wall 23 has a recess to receive one end of the spring and the bolt has a titprojecting therefrom to engage the `other end of the spring.

'I'he lock cylinder I0 is provided with the usual key operable tumblers 24 yieldingly projectable into one of four longitudinal tumbler receiving grooves 24', and retractible therefrom by the insertion of a proper key 25 to free the cylinder for rotation. Four-grooves are provided so that the key may be removed in either locked or unlocked position.

At its inner end portion, the cylinder has a bayonet slot comprising an arcuate groove 26 Engaged in this bayonet slot is a lug 28 forming part of. a pusher member 29. As best shown in Figure 10, the pusher member has a main body portion 30 which is slidably received in a. slideway 3| cored in the casing Wall above the open recess 20 and extending forwardly from the extreme inner end of the casing sufticiently far to communicate with the bore 9 and permit the lug 28 to engage in the arcuate groove 26. The forward end of the slideway is closed by an inclined wall 4I with which the pusher member engages to limit its forward movement and thus, through the engagement of its lug 28 in the arcuate groove 26, hold the cylinder against outward withdrawal.

'I'he rear end of the pusher member engages a shoulder 32 on the pivoted bolt so that upon inward endwise motion of the cylinder, the bolt I2 is rocked about its pivotal mounting against the action of its spring to a releasing position.

Inward endwise motion of the cylinder, however, is not possible except when the cylinder is turned to a predetermined unlocked position, which is the position of the cylinder shown in Figure 2. In any other position of rotation of the cylinder, a projection 34 on its inner end strikes the foremost step z3 of the wall 23 and thus prevents inward depression of the cylinder. The projection 34 and the front face of the wall 23 are so shaped that when the cylinder is turned to its unlocked position, its projection 34 clears the wall part 23' and permits inward endwise motion on the part of the cylinder until the cylinder head Ill contacts the bottom of the counterbore 9.

In this connection it is to be observed that the projection 34 has an inclined or spiral shaped edge 35 which is adapted to contact a similarly shaped surface 36 on the inner face of the wall 23 and force the cylinder outwardly upon retrograde rotation from'its unlocked position so as to insure positive return of the parts to their locked positions.

The projection 34 also has the function of preventing rotation of the cylinder to its position at which the lug 28 on the pusher member aligns with the gateway 2'I of the bayonet slot in which position of rotation, .the cylinder is removable. The removing position of the cylinder lies beyond its unlocked position of rotation shown in Figure 2. In the unlocked position of the cylinder, a fiat wall surface 3T on the projection 34 lies substantially in the plane of one side of the bolt to be engageable with an inwardly extending toe 38 on the bolt in bothits locked and unlocked positions to prevent rotation of the cylinder to its removing position except 'when the bolt is moved to a releasing position, shown in dotted linesin Figure 3.

In the releasing position of the bolt, the toe is moved clear of the obstructing surface 31 allowing the cylinder to be turned past its unlocked position to its removing position. Movement of the bolt to its releasing position requires direct manual actuation of the bolt. The normal unlocking of the bolt by depression of the cylinder cannot move the bolt to its cylinder releasing position as the depression of the cylinder is limited by engagement of its head with the bottom of the counterbore formed in the casing to receive the head.

As soon as the cylinder is turned past its unlocked position, the toe of the bolt may be permitted to ride on the conical outer surface 31' on the projection 34 thus obviating the necessity for holding the bolt down in its releasing position.

By virtue of the novel arrangement and relationship of the cylinder, the pusher member, and the bolt, the bolt spring is utilized to prevent rattling. It is to be observed that the pusher member has its top wall stepped which results in an edge 4I). 'Ihis edge 40 contacts the top of the slideway 3 I, and inasmuch as the pusher member has a degree of play in the slideway, it is free to rock about the fulcrum provided by the engagement of the edge 40 with the top wall of the slideway.

Upon such rocking movement ofthe pusher member, which is produced by the action of the spring 22 through the medium of the cam-like engagement between the pusher member and bolt, the forward end of the pusher member is pressed down onto the inner end of the cylinder.

Downward depression of the forward end of the pusher member is further assured by virtue of the fact that the pusher member is forced forwardly against the inclined closed end 4I of the slideway by the bolt, and the loose pivotal mounting of the bolt insures the proper functioning of the anti-rattle feature at all times at is permits the spring to yieldingly urge the bolt upwardly against the rear end of the pusher member.

If desired, the locking bolt may be mounted in the casing as in the modified embodiment of the invention illustrated in Figures 11Aand 12. In this construction, the pivot pin is eliminated and trunnions 43 are formed integrally with the locking bolt to project from the opposite sides thereof for engagement in round bottomed recesses 44 in the side walls'of open recess 45 in the inner end of the casing. Insertion of the trunnions 43 be readily apparent to those skilled in the art that this invention provides a novel spring bolt type of lock especially adapted for use with compartment doors of automobiles, and that the lock of this invention has many advantages over the past dead bolt type heretofore used forv this purpose.
