BACKGROUND AND SUMMARY OF THE INVENTIONThe present invention is directed to luggage and, more particularly, to luggage that is securable to an immovable object using existing carrying straps of the luggage.
Luggage, particularly of the backpack variety, typically comes with a pair of back straps which can be dunned over one or both shoulders for ease of carrying. Typically, such luggage has a criss-crossing zipper which traverses the entire backpack and allows dividing it into two constituent parts, for ease of access. Luggage of the backpack style is typically of a size that can be carried on the back and therefore easily prone to being pilfered because it can be carried with one hand and quickly removed unobtrusively.
Accordingly, it is a general object of the present invention to provide luggage, particularly of the type that includes carrying straps, where the carrying straps serve dual functions. One function is to enable threading the strap through an opening in an immovable object, for example, a leg of a desk or through the arm rest of a chair, and then locked back to the suitcase, so as to make it impossible (or at least difficult) to remove or walk away with the backpack.
The other objective of the invention is to provide and use the same mechanism to also lock the zipper of the backpack, to thereby provide dual functionality of locking the contents within the backpack and making removal of the backpack difficult.
The foregoing and other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE DRAWINGSFIG. 1 shows thetypical backpack10 which has a centrally located zipper12 with twozipper tabs14, each with a tab opening16 therethrough. Thelocking tabs14 can be moved from one side to the other side of the backpack, in well known manner.
Thebackpack10 has a pair of left andright shoulder straps20 and22. Theshoulder straps20 and22 have upper distal ends each of which is sewn or otherwise fixed to the body of thebackpack10. Theshoulder strap20 is similarly sewn at its other distal end, at the bottom of thebackpack10 as shown.
Theright side strap22 has at its opposing distal end a pair ofholes22A and22B. The strap at that location may be reinforced as compared to the rest of the strap, for example, it may be constituted of a metallic rectangular piece ofmetal24 that is strongly secured to thestrap22. Thelock shackle26 can be passed through thoseholes22A and22B, and then inserted into the openings of theaforementioned zipper tabs14.
A lock30 which may be a pad lock operated either with a key or as a combination lock, is sewn or otherwise secured to the bottom of the backpack, for example, by means of holding bands32,34. Theshackle26 which passes through the strap and also through the zipper tab(s) can then be inserted into the lock, thus locking the strap and zipper tabs near the bottom of thebackpack10. In this position, the straps can be used in the conventional manner.
As seen inFIG. 1, bothstraps20,22 can be adjusted in a length, in conventional matter, except it must be assured that the length adjusting mechanism for thestrap22 can not allow it to be opened in a manner which might defeat its being locked to the lock30.
As shown inFIG. 8, in typical use, a traveler will use thekey36 to free thestrap22 and then thread the free end of thestrap22 through the chair arm rest42 of thechair40, or through an opening in any immovable object, and then re-lock thestrap22, rendering theentire backpack10 immovable. Thus, a traveler can easily lock the backpack to the chair in which he is sitting or while waiting in an airport and allow himself to comfortably fall asleep without fear that somebody might actually walk away with the backpack or rummage through or pilfer its contents.
The invention is not meant to be limited to its precisely described embodiments, as it would be apparent to those skilled in the art that there are many offered manners in which the strap can be locked to the backpack. Also, the entire lock might be concealed within the body of the suitcase with access provided only for the shackle to be inserted into the concealed lock.
As noted above, many different locking mechanisms are available, as the present invention is not limited to the use of a pad lock style locking mechanism. Thus, inFIG. 3, the strap has connected to it a hookingstyle carabiner lock50 which comes with a spring loadedlocking arm52 and with alocking mechanism54 to be described. Thedistal tip56 of thecarabiner lock50 can be used to thread thezipper tab14 and through ahook58 which is a part of thebackpack10. Thehook58 can be metallic or made of strong cloth or the like.
As shown inFIG. 4, thelock54 is a combination lock. InFIG. 5, the lock is apush cylinder lock62 that has apush pin64 that is insertable into anopening66 as shown inFIG. 6. A carabiner style lock with a combination lock is shown inFIG. 7.
In accordance with another embodiment, thestrap22 can have affixed thereto one half of a buckle style locking device, where the complementary portion of the buckle is affixed to the backpack. The buckle style lock can be of the type which is described in U.S. Pat. No. 7,357,008, the entire contents of which are incorporated herein by reference. One example of such lock is shown inFIG. 3 of the U.S. Pat. No. 7,357,008, where one end of the strap is connected to the bottom of the backpack and the other hand connected tostrap22. In this style of a buckle lock, a string which is threaded throughtabs14 can be utilized to lock the zipper tabs to the buckle.
Still further, it is not necessary that the locking mechanism be provided at the bottom of the backpack, as it can be just as easily provided at the other distal end of the strap, near the top of the backpack. Also, a locking mechanism can be provided on bothstraps including strap20 andstrap22.
A similar buckle style lock is also described in U.S. Patent Application No. 2007/0226964, which published Oct. 4, 2007, the entire contents of which are incorporated herein by reference. The lock for the buckle style embodiment can be either of the type that uses a key or which uses a combination lock or both as described in the incorporated by reference documents.
It should be appreciated that the locking strap can also be used to be threaded through the handle of another piece of luggage and then through the immovable object, so as to lock two or more articles which require securing against theft.
The locking mechanism described herein is not necessarily limited to luggage and certainly not to backpacks and can be applied to any and all types of equipment which require securement. For example, rather than comprising straps at the rear of a backpack, the locking element may be installed at one end of one of the two handles typically provided in ladies handbags. Thus, the handbag may be secured against both theft and unwanted access to its contents.
Although the present invention has been described in relation to particular embodiments thereof, many other variations and modifications and other uses will become apparent to those skilled in the art. It is preferred, therefore, that the present invention be limited not by the specific disclosure herein.
