Abstract
A locking device capable of being readily converted from a coin controlled to noncoin controlled condition. A pivotal bolt shield is normally backed out of a bolt-blocking position by a coin which serves as a linkage element. This shield can also be retained in a swing-away position in which the bolt is not blocked. When the shield is in the latter position, the mechanism does not require a coin to operate.

German patents 604,04l and SI 1.406 show coin-operated locking mechanisms which utilized a coin as a link which is essential in order to accomplish locking of the mechanism.,These German patents show a removable plunger which can be secured in the locking mechanism by a bolt. The bolt cannot reach the plunger, in the absence of a coin, due to the presence of a bolt-obstructing shield. The inward movement of the plunger, when afcoi'n is in a linkage position, backs awaythe bolt-obstructing shield thus permining the bolt to engage and lock the plunger. Similar devices are shown in US Pat. .No.'2,982,388 and 3,028,941. The latter U.S.'patents show the use of similar locking mechanisms in conjunction with a coat rack. While such locking mechanisms are generally satisfactory in coinoperated checking facilities, they. are not readily converted from a coin-operated to noncoin-operated condition.
Restaurant operators may find it desirable to use such a garment checking facility in a coin-operated'condition, for exampleduring the evening dinner hours, and yet wishto convert theunit to a noncoin-operated conditiomfor example, for use in connection with} the luncheon trade, or for use in MA Y F-THEIN ENT 'QN.
- .en t nifaf l locking mechanism, a lockable traveler, is provided witha bolt-obstructing shield which is pivotal, and which can be backed out of bolt-obstructingposition by the inward movementof the lockable traveler when-a coin-is inserted. The shield is manually pivotable to a second position and retainable in thesecond position to permitciontinual contact of the-bolt against the lockable traveler. In-the latter condition the locking mechanism is noncoin-operated, and insertion of the traveler will cause'the traveler to be-locked, even without acoin.

2 DESCRIPTION OF PREFERRED EMBODIMENTS Reference to the drawings indicates the clothes rack at 10 having a headpiece section generally," and a garment support section generally I2. Each chain is secured to the headpiece section at one end and has an open, loop I7 at the other end. Open loops I7 are adapted to engage hooklike pro- -jections I8 which, extend forwardly of the supporting facings which support and carry locking mechanism. generally 21. The illustrated embodiment includes an optional decorative facing 22. Both support facing 20 and decorative facing 22 reside in slots 24 in headpiece framing members 25. Secondary support structures 26 and 27 are preferably spot welded to support facing 20 and decorative facing 22 is therefore desirable as a convenient, readily maintained facade to cover the spot weld marks on supporting facing 21) as illustrated. Secondary supports 26 and 27 are preferably platelike elements extending rearwardly from support facing 20, and having flanges 26', 27, extending at right angles therefrom, which are welded or otherwise secured to support facing 20. Shaded areas 29 indicate points at which spot welding is preferred.
Key locks, generally 31, include a normally retained, but removable key 32, a rotatable cylinder 33 and pivotal bolt 34 carried by rotatable cylinder 33. The lock mechanism is preferably a conventional mechanism of the type which retainskey 32in the'lock while the locking mechanism is in unlocked condition, but-releases key 32 while the locking mechanism is in locked condition. Thus while the cylinder 33 is in the position corresponding to the bolt'position indicated at A, or B, of FIG. 4, the key is automatically retained in the I key lock. When the locking mechanism is in the locked position and bolt 34is pivoted to the positionshown at C in FIG. 5,
the keyis released automatically. I

Traveling unit generally 44, includes'projection l8, shaft 42. plate 43, and traveler 45. Hooklike projection 18 is at the end'of shaft 42 which terminates with enlargedplatelike portion 43 and iswelded'to elongated traveler 45." Traveler 45 is slidably retained in opposing brackets 47, 47, 47". Top and bottom traveler projections 49, 49' assist in maintaining traveling unit 44 in proper horizontal orientation, thus facilitating sliding of traveling unit 44. Fingerlike projection 50extends laterally from traveler 45 across enlarged' portion 43 through opening'52'in secondary support structure 27 and terminates in rearwardlyextendin'g fingen53. Spring 54, which Pivotal shield is secured to secondarysupport structure 26"by axle rivet 6lz'ln the illustrated embodiment; pivoted' through more than 90 arc. The are is limited by facing sup port20 and ceiling 63 of enclosure 37. Spring65 'issecur'ed through hole 66 in secondary support member-26 at a point between rivet 61 and facing 20 on a level I approximately horizontal to rivet6l. The other end of spring 65is secured to tab 67 which is located at the other end of pivotal shield-60.
Thus when tab 67 is in that portion of the are which is below I I I the horizontal line through hole 66 and rivet 61, spring 65 locking mechanism taken from above and behind an embodi- 70:
During the frontward-backward movement of traveling unit 44, projecting fingers 49, 49' pass above and below finger 70. Thus the travel of the traveling unit has no effect with respect to the moving shield element 60 when a coin is not in what is referred to below as linkage position.
Thus the only additional component required to adapt the basic structure for use with a smaller coin is shim 77 which has sloped top surface 78. Thus when shim 77 is added to accommodate a smaller coin, such as an American dime, the coins drops from shunt 74', engages the top surface 78 of shim 77, and is moved rearwardly where it continues to drop until it strikes bottom stop 76'.
The only structures shown in F K]. are those structures shown in FIG. 9 which are altered, or added, in order to adapt the basic structure, which is dimensioned to operate with a larger coin, e.g. American quarter, for use with a smaller coin, e.g. an American dime.
OPERATION Whenever a patron wishes to check a garment using the apparatus of this invention, one of the chains is dropped through the sleeve of the garment 13 either before or after it is placed on hanger 14, and end loop 17 of chain 15 is placed over hooklike projection 18. Should the patron attempt to turn the key 32 at this stage the rotation of the bolt is limited in one direction by shield 60 or by the side of traveler 44, should shield 60 be swung to position D and is limited in or the other direction by bolt stop 79. The purpose of bolt stop 79 in limiting upward rotation of bolt 34 is the prevention of the generation of excessive velocity as the bolt strikes pivotal shield 60. Bolt 34 is biased in the direction of shield 60 by spring 80 which is secured below the key lock 31 to post 81. In the absence of bolt stop 79, bolt 34 could be swung upwardly beyond position indicated as A in FIG. 3. by rotation of key 32. Release of key 32 while the bolt is rotated substantially beyond position A in FIG. 3 causes the bolt to slam downwardly against bolt-restraining surface 69 and this occasionally causes bolt 60 to bounce rearwardly a sufficient distance to pen'nit the locking of the unit without insertion of the coin. By placing bolt stop 79 in a position which substantially limits the rotation of pivotal bolt 34 in the direction away from shield 60, this undesirable characteristic is eliminated.
Should the patron push hooklike projection 18 inward without prior insertion of a coin, traveler unit 44 simply moves rearwardly against the biasing force of spring 54, and fingers 49, 49 simply move above and below lateral projection 70 on shield 60 and nothing further happens in the locking mechanism. Thus as soon as the patron stops pushing inwardly on projection 18 the biasing force of spring 54 returns travel unit 44 and projection 18 to the initial position.
However, when an appropriately sized coin 40, 40' is placed in slot 71 in facing support 20, the coin enters enclosure 37, is stopped by first stop 73, 73 and commences to drop by gravity against shunt 74, 74' until downward motion is terminated when the coin strikes bottom stop 76. 76. The dimensioning between lateral projection of traveling element 44 and lateral projection 70 of shield must be such that the coin can fall therebetween, and yet provide a push-linkage therebetween when traveling element 44 is moved rearwardly. Thus after insertion of the coin pushing traveling element 44 inwardly, e.g. by pushing in on hooklike projection 18, moves the coin rearwardly until it strikes lateral projection on shield 60. Continued rearward motion of traveling element 44 thus causes continued rearward motion of shield 60, e.g. as shown in H0. 6. Thus the bolt is no longer restrained by shield 60 and presses against the side of traveling element 44-due to the biasing of spring 80. As soon as the enlarged portion 43 of traveling element 44 moves behind the bolt 34 the biasing action of the spring causes the bolt to pivot in front of portion 44, and into the path of traveling element 44 as illustrated in FIGS. 5 and 6.
It is noted that shield 60 has an angular edge 68 below the bolt-restraining edge on notch 69. This edge 68 functions to facilitate the dropping of the coin out of the locking mechanism. Thus the instant traveler 45 has moved the coin 40 and shield 60 rearwardly enough to push bolt restraining surface 69 behind the bolt 34, the sudden downward snap of bolt 34 along edge 68 which is angled under the path of the bolt, snaps shield 60 rearwardly. This rearward snap is so quick that the shield 60 moves rearwardly faster than the coin. Thus at the moment of the snap the coin is no longer engaged between fingers 50 and 70 as a push-link, but is free, rearwardly, and is pushed by finger 50. Thus, the coin commences to fall under force of gravity the instant bolt 34 clears restraining surface 69.
It has been conventional to provide locking mechanisms similar to a key lock 31 in which design key 32 cannot be removed from the lock while bolt 34 is in any position, e.g. from position A to position B as shown in FIG. 3, other than the locked position. When bolt 34 rotates to the position indicated at C in FIG. 5, i.e. to the locked" condition, the key 32 can be removed from key lock 31.
It is preferred that key 32 be partially ejected from the lock as soon as the lock is in locked position. This is preferably accomplished by providing piston 83 having an enlarged end portion 84 and narrow shaft 85. The end of the enlarged portion 84 is positioned to bear against the end of key 32 and the rear surface of portion 84 adjacent to shaft 85 serves as a flange or a collar to engage compressed spring 86 which is retained by cap nut 87. Thus as soon as key 32 is released it is partially ejected. Key 32 can be removed from key lock 31 when bolt 34 is in lock position and hooklike projection 18, forming a locking encirclement around end loop 17, cannot be moved outwardly to release end loop 17 without the use of the key. Reinsertion and turning of the key to raise or pivot bolt 34 permits traveling unit 44 to slide forwardly under the biasing forces of spring 54 until lateral projection 50 strikes facing support 20, thereby returning the hooklike projection to the "unlocked" position as is shown in H0. 4. Also, elevation of automatically the locking mechanism is returned to the coinoperated condition. That is, bolt 34 cannot engage, i.e. ob-
struct, traveling unit 44 until shield 60 is again backed from under bolt 34.
CONVERSION TO NONCOlN-OPERATED CONDITION To convert the locking mechanism of this invention to a noncoin-operated condition, it is simply necessary to back the rotating shield 60 to that portion of the are through which shield 60 can swing in which the shield does not obstruct the bolt from engagement with traveling element 44. This is most conveniently done in the embodiment shownby simply elevating shield 60 to the position indicated at D in FIG. 6. in the embodiment shown spring 65 biases shield 60 upwardly against ceiling 63, thusretaining shield 60 in this position. Alternative structures may beemployed for retaining shield 60 in that portion of its arc in which it does not obstruct the pivoting of bolt 34. It will be appreciatedthat any means which serves to retain the shield 6(l in that portion of the arc will serve to maintain'the locking mechanism in the noncoinoperated condition.
Thus, whenever shield 60 is-maintained in the second portion, i.e. nonbolt obstructing portion, of its swingable arc, bolt 34 is urged against traveling element 44 when. the locking mechanism is in its unlocked position. Pushing of the hooklike projection 18 inwardly then causes traveling element 44 to slide against bolt 34 until finally bolt 34 falls in front of en-.
.larged portion 43 thus preventing reverse, or outward movement oftraveling element 44. Again the key is automatically partially ejected'from keylockjl when the bolt 34 is in the chain the patron must now insert the key and rotate the key in bolt 34 until bolt34 is rotated out of the path of traveling element 44. Because of the continuous biasing forces exerted by spring 54 traveling element 44 slides forward as soon as the bolt 34 is cleared. Release of the key now brings bolt 34 down against the side of traveling element 44, in which condition it. is again ready for immediate'relocking without the use of a coin.
ACHIEVEMENTS It will be appreciated from the foregoing specification that this invention permits themanufacture of the basic" locking mechanism which can be conveniently and economically modified during manufacture to set the mechanism for use with various sized coins.
It is also apparent that the mechanism can be almost instantly converted from a coin operated to a noncoin-operated condition by maintaining shield 60 in a nonbolt obstruction portion of its swingable are. it is also apparent that the mechanism can be instantly reconverted from noncoin operation to coin-operated condition by releasing shield 60 and permitting it to reside in the bolt-obstructing portion of its swingable are. lt is further noted that the invention requires the use of no tools, and no special skills in order to convert the mechanism from coin-operated to noncoin-operated condition. 5
Moreover, the apparatus of this invention is eminently satisfactory either as a coin operated unit, or a noncoinoperated unit. Thus the manufacturer can supply a single article even if the customer needs it solely for use as either a coinoperated unit, or anoncoin-operated unit. Moreover, if a customerwants only a noncoin-operated unit, the same mechanism from facing 20 and rearwardly can be supplied, (except that shield 60 issecured in its swung-away position) and a decorative facade inserted instead of 22, which is identi- -cal to 22 in every respect but lacking coin slot 71. The
economic advantages flowing from the unexpected, high degree of flexibility of the basic locking mechanism provided in this invention are readily apparent.
