Abstract

ABSTRACT OF THE DISCLOSURE

A conventional barrel-type combination lock receives a lock element extending from a safety pin housing. The safety pin housing pivotally receives a pin that pivots between an open position and a closed position. When the pin is placed in the closed position relative to the safety pin housing, and the lock element of the barrel-type combination lock is moved to the locked position, the end of the pin is positioned within a pin receiving recess on the barrel-type combination lock so that the pin is locked in the closed position. A conventional chain formed from a series of interlocking links is utilized with the lockable safety pin to enable small articles to be locked to fixed objects. When the chain is not in use, it is stored within a cylindrical chain storage container that, is threadedly received upon the end of the barrel-type combination lock. With the pin closed and the combination lock in the locked position, and with the chain positioned within the storage container and the storage container threaded onto the lock, the personal locking device is of a size convenient for carrying in a purse or pocket of the potential user.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to the drawings, and particularly to Figures 1 and 2, there is shown a personal locking device 10 having a barrel-type combination lock 12 which is conventional in design and therefore will not be described in detail. Known barrel-type combination locks are disclosed in United States Patents 1,222,920; 1,267,89q; 1,472,206, and 1,627,462.
In conventional fashion, the lock 12 has a barrel 14 upor which are received a plurality of tumbler wheels 16. The tumbler wheels have recesses ~not shown) so that when the recesses are aligned, the lock is in an open position. When the recesses are not aligned, the lock is in a locked position in a manner that is well known in the art. The tumbler wheels 16 have numerals (not shown) around the circumference of each ~ 3~
wheel 16 so that when the recesses are ~ligned the numerical ¦ combination of the lock appears in alignment on adjacent ¦ tumbler wheels in conventional fashion. Even tho~gh the above ¦ combination lock is described for use with the present invention, it should be understood that other types of locks, such as conventional key locks, are equally adaptable to the present invention.
Formed in one end of the barrel 14 is a pin receiving recess 18 A lock element 20 is positioned in a central bore 21 of the barrel 14 and moves in sliding, axial relation to the barrel 14 between the locked position shown in Figure 1 and the unlocked position shown in Figure 2. Again, in conventional fashion, when the tumbler wheels 16 are positioned so that the lock is in the open position, the lock element 20 is freely slidable through the barrel 14.
In order to lock the combination lock 12, the lock elernent 20 is moved to the position shown in Figure 1. Then the tumbler wheels 16 are rotated. In the locked condition, the tumbler wheels 16 enter recesses 22 formed on the lock element 20 and prevent the lock element from moving~
Affixed to one end of the lock element 20 is a stop member 24 which is movable toward and away from an annular wall 26 of barrel 14 when the lock element 20 is moved between the open and closed positions as shown in Figures 1 and 2. The stop member 24 prevents lock element 20 from being completely ~L~4~3 withdrawn from the barrel 14. A ~pring 2S surr~ur,ds the lock element 20 and abuts at end the stop member 2~ and at the opposite end the barrel ann~lar wall 26. The spring 25 exerts a force on the stop member 24 to normally urge the lock element 20 into the barrel bore 21, as shown in Fiyures 1 and 6. The spring 24 is shown in a compressed position in Figure 2.
Affixed to the opposite end of lock element 20 from stop member 24 is a safety pin housing 28 which is of generally cylindrical shape and which has a recess 30 formed therein.
The safety pin housing 28 also has a groove 28a formed to receive the pivoted end of a pin 32. The pin 32 is movably retained on the housing 28 by pivotally connecting the pin 32 to the housing 28 by pivot 34. The housing 28 also has a pin receiving groove 36 to receive the free end of pin 32 when the pin 32 is in the closed position as shown in Figure 1~
As is best seen in Figure 1, when the pin 32 is closed the free end of pin 32 fits into pin receiving groove 36 of housing 28. A portion of pin 32 protrudes beyond safety pin housing 28 and into the pin receiving recess 18 of barrel 14.
With the lock element 20 in the locked position shown in Figure 1, the pin 32 is locked in the closed position and may not be opened. When lock element 20 is moved to the open position shown in Figure 2, the end of pin 32 is withdrawn from pin receiving recess 18 and may be pivoted about pivot 34 to the open position shown in Figure 2. Threads 38 are formed ~ 3 on the end of the barrel 14 opposite from safety pin housing 28 to threadedly receive a cylindrical chain storage container 40. The chain storage container 40 has threads 42 formed thereon which mate with threads 38 formed on barrel 14. The cylindrical chain storage container 40 is preferably formed from a lightweight material such as a rigid plastic or aluminum. The mating threads 38 and 42 can be eliminated for a frictional engagement of the container 40 and barrel 14.
A chain 44 is provided for use as part of the personal locking device of the present invention~ When the locking device is not in use, the chain is stored within the storage container 40 as shown in Figure 1. The chain 44 is formed from a plurality of individual interlocking links 46 in conventional fashion.
In one embodiment the chain 44 is a single continuous loop that twice passes through a choke 48 (shown in Figure 7) formed of a body member 50 having a pair of passages 52 through which the chain passes. In another embodiment (not shown) the chain 44 is a selected length having unconnected end portions. In operation, the choke 48 can be moved alony the chain to vary the effective size of the loop of the chain 44.
When the personal locking device 10 is in the locked position as shown in Figure 1 and the chain 44 is stored within the storage container 40 as shown in Figure 1, the ~ 'a3 ¦ entire pers~nal locking device lO has an over~ll length of ¦ approximately seven inches and has a diameter of approximately ¦ one inch. It is lightweight and may be readily c~rried in the purse or pocket of the user until the device is needed for use. .
Figure 8 illustrates one example of use of the locking device lO to lock a garment~ such as a coat 54 to a wall hook 56, First one end of the loop chain 44 is wrapped tightly around the wall hook 56. The choke 48 is advanced on the chain 44 to close the loop of the chain 44 tightly around the hook 56. With the choke 48 in this position, the pin 32 is passed through the links 46 that are closest to the choke 48 as shown in Figure 8. The coat 54 is then secured to the chain 44 by passing the unlocked pin 32 through the hole of the zipper closure 58 of coat zipper 60. The pin 32 is then inserted, as above described, in the barrel recess 14 to lock the pin 32 in the closed position. Thus the chain 44 is locked to both the coat 54 and hook 56.
¦ Figure 9 illustrates a similar example of use of the locking device lO to secure a handbag 62 to an arm 64 of a chair 66. In this application the chain 4~ is :looped around the arm 64 and through itself to form a noose 68 around the arm 64. In this case the choke 48 is left free to slide on the chain 44 because the noose 68 around the chair arm 64 prevents separation of the chain 44 from the chair 66.
The locking device lO is then secured to the handbag 62 ~y passing the open pin 32 through an aperture, or the like, in a ~ ~94~f~3 closure element 70 of hand~ag 62. Conventionally the element 70 extends through an opening 72 of a flap 7q of the handbag 62 to close the handbag. When the pin 32 is moved to the locked position on the barrel 14 not only is the device 10 secured to the handbay 62, the handbag flap 74 is locked in a closed position, as seen in Figure 9.
It should be understood that the personal locking device of the present invention can be utilized to secure any number of small articles such as a handbag or a garment to fixed objects. The above examples are only representative of a few of the many applications of the locking device 10 of the present invention.
Now referring to Figures 10-14 there is illustrated the feature of the present invention of integrally incorporating the locking device 10 in a luggage handle 76 or the like to not only facilitate securing the associated luggage to a stationary nbject but facilitate efficient integration of the locking device 10 and luggage handle 76 when ~he locking device 10 is in use and when not in use.
The luggage handle 76 is specifically adapted for u.se with the locking device 10 even though the handle 76 is substantially converltiollal in design. As seen in Figures 10 and 11 the handle 76 includes an elongated tu~ular body i port 78 supported adjacent opposite end 80 and 82 by .,, ~ L'a3 integral post~ 84 and 86. The extreme er.d~ o~ the posts receive pins 88 by which the handle 76 i~ convenkionally 6ecured to the frame of a piece of luggage, brie~c~se, purse or the like (not 6hown).
The body portion 78 may be Gelectively fabricated.
For example it can be molded plastic, metal cast, all leather constructed or a combination of these and other ~uitable materials. The body portion 78 is formed preferably with the end 80 closed and the end 81 open to receive the entire locking device 10 with the 6torage container 40 attached to the barrel 14 in a cavity 83.
To accommodate storage and use of the locking device 10, the body portion 78 adjacent the end 82 has oppositely ¦ positioned apertures gO and 92. Aperture ~0 shown completely ¦ in Figure 10 is positioned to expose the connection of the pin 32 in the pin receiving recess 1~ vf the barrel 13 The aperture 90 is enlarged to the degree to permit movement of ¦ the pin 32 into and out of locked position as shown in Figures l ¦ 12 and 13.
¦ The aperture 92, shown co~nple~ely in Figures 11 and ¦ 14, is positioned on the opposi.te side of th~ body portlon 78 ¦ to expose the ~umbler wheels 16 of the combination lock 12 ¦ when the lock 12 is in an operative position within the cavity ¦ 83 of the body portion 78. The wheels 16 are exposed to permit ¦ manipulation of the wheels for unlocking the pin 32 from the barrel recess 18.

~ 4~3 Associated with the aperture 90 on one side of the hody portion 78 is an elongated slot 94 that extends from an opening 96 at end 82 to a closed end portion 98 which is spaced closely to the aperture 90. The slot 94, as shown in Figures 12 and 13, receives the pin 32 as the lock 10 is advanced into the cavity 96. With this arrangernent the pin 32 extends out of the cavity 83 and overlying the body portion 78. The free end of the pin 32 overlies the aperture 90 for pivotal movement into and out of engagement with the aligned groove 36 and recess 18 to thereby lock and unlock the locking device 10 to the luggage handle 76.
As shown in Figure 13 the chain 44 is used with the pin 32 as above described. With the pin 32 in the open position shown in Figure 12, selected links 46 of the chain 44 are positioned on the pin 32. Thereafter the pin 32 is moved to the closed position shown in Figure 13 to lock the chain 44 to the locking device 10. This has the effect of locking the chain 44 to the handle 76 and the associaked luggage. Thus a convenient arrangement is avai.lable for securing the lugc3age by the locking device 10 to a stationary object. At the sarne time the locking device 10 becomes an integral part of the luggage.
The locking device 10 is always conveniently available for use on the handle 76. When not needed for locking operations, the chain 44 is stored in the container 40 and the locking device 10 is, in turn, locked to the handle 76 preventing removal of the device 10 from the harldle 76. In operation with the chain 44 secured to the pin 76, a variety of methods can be utilized, as above discussed to secure the chain 44 to a stationary object.
According to the provisions of the patent statutes, we have explained the principal, preferred construction and mode of operation of our invention and have illustrated and described what we now consider to represent its best embodiment. However, it should be understood that, within the scope of the appended claims, the invention may be practiced otherwise than as specifically illustrated and described.
