Rhodes, Inc., Hartford, Conn., a corporation of Delaware Filed June 12, 1964, Ser. No. 374,698 3 Ciaims. (Cl. 70-116) The present invention relates to a lock assembly having notable utility for locking the coin receptacle door of a parking meter.
The principal object of the present invention is to provide an improved parking meter `door lock assembly having a sturdy and compact assembly of parts of economical construction and facile assembly and providing increased effectiveness against tampering and attempted destruction.
Another object of the present invention is to provide an improved parking `meter coin receptacle door lock aS- sembly having increased effectiveness in preventing illegal access tothe coins deposited in the receptacle.
A further object of the present invention is to provide a parking meter door lock assembly having a key-operated lock subassembly which may be readily detached for repair or replacement.
Other objects will be in part obvious and in part pointed out more in detail hereinafter.
The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will 'be exemplified in the construction hereafter set forth, and the lscope of the application of which will be indicated in the appended claims.
In the drawings:
FIG. 1 is a fragmentary side elevation view, partly broken away and partly in section, of a parking meter coin receptacle assembly incorporating an embodiment of a door lock assembly of the present invention;
FIG. 2 is a fragmentary view showing a pair of locking bolts of the door lock assembly in their fully extended or locking positions;
FIG. 3 is a fragmentary view with parts removed showing a portion of the door lock assembly in more detail;
FIG. 4 is a fragmentary section View of the door lock assembly;
FIG. 5 is a rear view of a support bracket of the door lock assembly; and
FIG. 6 is a side view of the support bracket.
Referring now to the drawings in detail, an exemplary embodiment of a parking meter lock assem-bly of the present invention is mounted for locking a generally rectangular door 1t) within a conforming recess -12 of a parking meter coin receptacle 14 for preventing access to an opening 16 therein, the receptacle including the door being, for example, constructed of ductile iron for security. In a well-known -manner a suitable coinoperated timing mechanism (not shown) is mounted on the receptacle 14 and coins inserted into the timing mechanism are deposited in the receptacle via a coin chute Z0 and are stored therein until removed by unlocking the receptacle door 10, for which purpose a fixed coin box 22 having a downwardly inclined bottom Wall 24 may be provided in the receptacle.
For opening the door 10 outwardly of the recess 12 and clear of the access opening 16, the door is mounted by a hinge bracket 30 having an apertured base 32 and a pair of opposed parallel sides 34 extending normal thereto. The hinge bracket is pivotally connected to a pair of opposed generally L-shaped hinge supports 38 which are secured to pairs of vertically spaced lugs 46 of the receptacle by machine screws 42. Accordingly, with the door 10 withdrawn from the receptacle access opening, the door subassembly including the hinge bracket 30 and the hinge supports 38 may be readily detached from the receptacle enclosure by the removal of the machine screws 42, and with the door locked in the recess 12 access to the interior of t-he receptacle is prevented.
The door lock assembly of the present invention, generally denoted by the numeral 80, includes a bolt `subassembly 82 comprising a support bracket 84 and a cover plate 86 which together are secured by machine screws 90 to inwardly projecting posts 88 of the door 10 whereby a generally iiat base portion 92 of the support bracket is spaced generally parallel to but inwardly of the door. Upstanding from and integrally formed with the flat base portion 92 of the Isupport bracket are a pair of parallel side anges 94 which, as best seen in FIG. 1, are pivotally connected to the free ends of the sides 34 of the hinge bracket 30 by a pair of pivot pins 96. The cover plate 86 is formed with a pair of laterally spaced inwardly offset bridge portions 98 which with the base portion 92 of the support bracket S4 define laterally extending coaxial channels slidea'bly receiving a pair of oppositely extending bolts 100 -of substantially rectangular plate construction. -The upstanding side flanges 94 have rslots 102 receiving and guiding the bolts, and the cover plate 86 is provided with two pai-rs of projections 104 with opposed parallel edges 106 engageable with the edges of the bolts, it being seen therefore that the side flanges `94 and the opposed edges 106 provide edge bearings for the bolts and that the bridge portions 98 and the base portion 92 provide face bearings for the bolts.
Referring to FIG. 4, a key-operated lock subassembly, generally denoted by the numeral 110, is mounted substantially between the door 10 and the `support bracket 84. The door is provided with a central key opening 112 for insertion of an appropriate key, and, as seen in FIG. 4, the key opening 112 may be enlarged at its outer end to receive a hardened knurled bushing 113 press t iiush with the face of the door to resist illegal access to the contents of the receptacle by enlargement, as by drilling, of the key opening 112. For axial alignment of the lock subassembly with the key openin-g 112, the door 10 is provided with an inwardly projecting cylindrical boss 114, and a support housing or bushing 116 of the lock subassembly is provided with a bore portion 118 for revolvably -supporting the lock subassembly on the boss 114 with the outer end of the bushing abutting the door. A bore portion 124 of lesser diameter than the bore portion 118 and of greater diameter than a remaining bore portion 126 of the bushing provides an annular shoulder 127 for retaining an enlarged outer end 128 of a key-operated cylinder lock 129 against inward axial displacement. For protection of the lock 129, a guard washer 131) having a central key slot is revolvably mounted in the bore portion 118 between the face of the lock and the boss 114.
The lock 129 comprises a Icylinder 136 with threaded partially cylindrical portions 138 and intermediate diametrically opposed parallel flat portions having axially extending integral keys 142. For retaining the cylinder 136 against angular displacement within the bushing 116 there are integrally formed Ion the bushing adjacent the inner face thereof a pair of lateral projections 137 with opposed edges engaging the flat portions 140 of the cylinder and with slots receiving the keys 142. The lock 129 incorporates a key-operated plug 139 which in the present embodiment has an inwardly projecting mounting nut or cam support 141 contoured for receiving a stop cam plate 143 and a bolt cam plate or locking lever 145, the cam plates 143, being detachably retained on the cam support 141 by a lock washer 147 and a screw 148 threaded to the plug. The stop cam plate 143 cooperates with a stop 144 formed on the inner face of the lock cylinder to limit the angular freedom of displacement of the plug to substantially 90, and the bolt cam plate is positioned to overlie the bolts as seen in FIG. 2. For translating the angular displacement of the plug 139 into lateral rectilinear displacement of the bolts, the bolt cam plate 145 is provided with a pair of camming slots 150 and the bolts are provided with upstanding pins or followers received therein, it being understood that when the door is fully inserted in the recess `12 of the receptacle and the bolts are fully extended as shown in FIG. 2 the bolts are positioned to overlie the plates 38 between the lu-gs 46 (FIG. l) to lock the door.
For facilitating assembly and removal of the lock subassernbly 110, the bushing 116 is provided with an elongated or oblong radial flange or end face 1545 having diametrically opposed radially extending flange por-tions 156 and intermediate parallel fiat portions 15S, andthe base portion 92 and the cover plate 86 of the bolt subassembly are provided with oblong openings 160, 162 substantially conforming thereto for axial insertion of the bushing therethrough. For axially retaining the bushing 116 on the door, the bushing is angularly offset from its inserted position, preferably substantially 90 as shown in FIG. 3, to position the bushing flange 154 in overlying abutting engagement with the base portion of the support bracket, for which purpose the base portion 92 may have spot welded thereto a pair of parallel retaining plates 164, shown to be identical7 for abutment by the bushing flange 154 for increasing the strength of the support bracket against inward deflection. The bushing 116 is keyed to the support bracket to retain this abutting engagement as by a machine screw 17) threaded to the flange and having an enlarged head received in pockets formed in the cover plate 86 and the base portion 92 and engaging one of the retaining plates 164.
Thus, it can be seen that the machine screw 170 becomes accessible by the removal of the screw 148 and the cam plate 145 and that by the additional removal of the machine screw 170 the lock subassembly can be readily detached from the door for repair or replacement. Additionally, the lock subassembly is firmly retained between the base portion 92 of the support bracket and the door and attempted destruction of the lock as by driving a tool, such as a punch, against the guard washer 130 would be greatly resisted. Moreover, even if the lock plug were driven out of the lock cylinder inwardly through the aperture in the hinge bracket, the locking bolts will continue to serve to maintain the door locked.
As will be apparent to persons skilled in the art, various modifications and adaptations of the structure above described will become readily apparent without departure from the spirit and scope of the invention, the scope of which is defined in the appended claims.
