Another notched tab and buckle fastening device, also not readily detachable, is shown in US Pat. No. 1,619,803 to Behrman. Examples of toothed garment fasteners may be found in US. Pats. No. 3,214,810 to Mathison and No. 1,343,514 to Lindsay. A dog collar fastener, which also is not easily detached, is shown in US. Pat. No. 2,900,696 to Bacon. An essentially permanent bundling strap fastening device is shown in US. Pat. No. 3,618,173 to Schwartz.

SUMMARY OF THE INVENTION An embodiment of the present invention is a quick release strap locking device comprising a tab, attachable to a first strap end, having a first side which includes a notch, a buckle, attachable to a second strap end, having a passageway and a resiliently attached arm which has a tooth, the tab being in the passageway and the arm having a first position in which the tooth is exterior to the notch, and means for moving the arm into a second position in which the tooth is in the notch and for alternatively moving the arm to assume the first position, the movement of the arm being along an arc which intersects the centerline of the tab.

It is an object of the present invention to provide a mechanically simple quick release strap locking device.

Further objects and advantages of the present invention shall be apparent from the following detailed description.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of an embodiment of the present invention in an unlocked position prior to the insertion of the tab.

FIG. 2 is a perspective view of the embodiment of FIG. 1 with the tab inserted and in a locked position.

FIG. 3 is a perspective view of another embodiment of the present invention shown in an unlocked position prior to the insertion of the tab.

FIG. 4 is a perspective view of the embodiment of FIG. 3 in a locked position after the insertion of the tab.

FIG. 5 is a perspective view of the embodiment of FIG. 3 in an unlocked position prior to removal of the tab.

DESCRIPTION OF THE PREFERRED EMBODIMENT For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the embodiment illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended, such alterations and further modifications in the illustrated device, and such further applications of the principles of the invention as illustrated therein being contemplated as would normally occur to one skilled in the art to which the invention relates.

Referring in particular to FIGS. 1 and 2, there is shown a locking device 11 according to the present invention. A tab 12, having a plurality of notches such as 13 and 14 along two opposite sides, is provided at strap end 16. Buckle 17 is provided at strap end 18. Strap ends 16 and 18 may be ends of the same strap or different straps depending upon the application in which the locking device 11 is to be used.

Buckle 17 includes passageway 19, which is of slightly larger cross-section than tab 12. Extending beyond buckle 17 are arms 22 and 23, which are resiliently attached to buckle 17. Preferably, arms 22 and 23 are integral with buckle 17. Tooth 24 at the end of arm 23 and tooth 26 at the end of arm 22 are provided for engaging notches such as 13 and 14 on tab 12 as shall be described more particularly hereinafter.

Slidably mounted on buckle 17 is sleeve 21, which is slidable over the main portion of buckle 17 which defines passageway 19 and also over arms 22 and 23. Provided on buckle 17 is stop 27 to prevent sleeve 21 from sliding off the end of buckle 17. Detent 28 is also provided on buckle 17 to maintain sleeve 21 in a locking position over arms 23 and 22, as shown in FIG. 2 and shall be more particularly described hereinafter. Sleeve 21 is prevented from sliding over the ends of arms 22 and 23 due to the thickness of the arms in the area of teeth 24 and 26.

As shown in FIG. 1, tab 12 is inserted into passageway 19 in the direction of arrow 29. Tab 12 is moved through passageway 19 and beyond the armed end of buckle 17 as shown in FIG. 2. When tab 12 is positioned as shown in FIG. 2, sleeve 21 is moved in the direction of arrow 31, away from its initial position near stop 27 and over arms 22 and 23 to a position beyond detent 28. At this time, sleeve 21 is held in position between detent 28 and the toothed ends of arms 22 and 23. Teeth 24 and 26 are held in locking engagement within a pair of oppositely disposed notches such as 13 and a corresponding notch on the other side of tab 12, the points of the teeth and the notches being inclined toward the direction of insertion of tab 12 through buckle 17 (arrow 29). With the teeth thus engaged in the notches, tab 12 is held within buckle 17 and is not removable therefrom. When it is desired to remove tab 12 from buckle l7, sleeve 21 is distorted slightly by applying pressure to grooved ends 32 and 33, which enables sleeve 21 to be moved over detent 28 and back to its position near stop 27 as shown in FIG. 1. At this time, resilient arms 22 and 23 return to their position as shown in FIG. 1, teeth 24 and 26 become disengaged from the notches in tab 12, and tab 12 may be easily removed from within buckle 17.

In FIGS. 3, 4 and 5, there is illustrated another embodiment of the present invention. Locking device 41 comprises tab 42 and buckle 47. Tab 42 has a plurality of notches such as 43 and 44 along two of its opposite sides and is attached to strap end 46 (FIG. 4). Buckle 47 contains passageway 49 and is attached to strap end 48. Strap ends 46 and 48 may be ends of the same or different straps depending upon the application in which the locking device is used. The inside dimensions of passageway 49 are slightly larger than the crosssectional dimensions of tab 12.

Buckle 47 includes a pair of levers having first ends 51 and S2 and second ends 53 and 54, respectively. First ends 51 and 52 include teeth 56 and 57 respectively (FIG. 3) directed toward one another.

In operation of the locking device 41, tab 42 is inserted through passageway 49 of buckle 47 in the direction of arrow 58 (FIG. 3). The notches such as 43 and 44 in tab 42, and teeth 56 and 57 on the lever ends, are inclined toward the direction of arrow 58 so that, although teeth 56 and 57 are within the path of tab 42 as tab 42 is extended beyond passageway 49 in the direction of arrow 58, they and/or the tab teeth defining notches 43 and 44 can be resiliently cammed or deformed sufficiently that tab 42 can move past teeth 56 and 57. As shown in FIG. 4, after tab 42 has been inserted through passageway 49, and teeth 56 and 57 engage notches such as 43 and a corresponding notch on the other side of tab 42, they prevent the removal of tab 42 from buckle 47.

As shown in FIG. 5, when it is desired to remove tab 42 from buckle 47, arms 53 and 54 are forced together in the direction of arrows 61 and 62, which spreads apart arms 51 and 52 and releases teeth 56 and 57 from the notches in tab 42. Tab 42 may then be easily removed from buckle 47 in the direction of arrow 59 (FIG.

The material preferred for all parts of both embodiments is resilient plastic with a memory, such as nylon, for example. Therefore, both embodiments are reusable.
