DETAILED DESCRIPTION OF THE DRAWINGS
Referring first to FIGS. 1 to 4 the side squeeze buckle 100 has a female receptacle section 101 and a male latch section 102 which functions similar to known prior art side squeeze buckles. The male latch section 102 has a pair of arms 108 with tabs 103 on each side that engage holes 104 on the female 101 side to lock the buckle 100 together. The buckle 100 is made from a substantially rigid material such as plastic that retains its shape but can be flexed enough to press the tabs 103 inward enough to disengage the tabs 103 from the holes 104 to allow the two sections to be pulled apart, as can be seen in FIG. 5. One or both of the sections adjustably or fixedly holds a strap or belt around crossbars or the like. In the depicted embodiment, each section has an attachment location 105 and 106, which are single slots. Other known attachment locations could be used as well, including multiple slots for adjustable connections to straps, round holes or other known forms. No limitation is intended or inferred.
The male section 102 has a central section 107 extending from the attachment location 105 and flanked on two sides by arms 108 bearing tabs 103, as can be seen in FIG. 5. The two arms 108 are spaced apart from the central section enough to allow the arms 108 to be flexed inward enough allow the buckle 100 to open as described above. The central section 107 has a cavity 109 with a lid 110. In the current disclosure, the lid 110 and the bottom surface 125 of the central section 120, seen in FIGS. 1 and 4, form a large section of the top and bottom surface of the closed buckle. The female section 101 has two arms 118 extending around a central opening 120. The two arms 118 have recesses 104 that interlock with the tabs 103 of the male section 102. The shape of the central opening 120 of the female section 101 corresponds to the shape of the central section 107 of the male section, forming an interlocked whole. The female section has a top surface 119 and a bottom surface 124. The top surface 126 of the closed buckle 100 is formed by the top surface 110a of the lid and the top surface 119 of the female section 101, as seen in FIGS. 2 and 9. The interlock of the two surfaces must be close enough that there are no large gaps that could be snagged or otherwise caught. The top surface 110a of the male section forms at least 50 percent of the top surface 126 of the closed buckle. When the buckle is closed, the two sections interlock, such that the interlocked parts form the majority of the buckle. Lines A and B in FIG. 2 indicate the end points of the male and female sections respectively in the closed buckle. The part of the buckle between lines A and B is the interlocked section 130. In most side squeeze buckles only the attachment locations are outside of the interlocked section.
Referring next to FIGS. 7 and 8, in some embodiments of the buckle the female section 101 has a stabilizing member 121 inside the central opening 120 extending from the back wall 130. The stabilizing member 121 engages with slot 123 in the front end 122 of the central section 107 of the male section 102 when the buckle is closed. The interlocking of the stabilizing member 121 and slot 123 helps stabilize the closed buckle in place, helping to prevent flexing of the closed buckle.
The lid 110 has LED 111 and switch 112 integrated onto the top surface 110a of the male section 102 in the depicted embodiment. In this configuration the LED acts as a blocking element to reduce the likelihood of the button being activated by accident. The LED could be recessed if desired. As will be discussed below, the light and the switch can be at other locations; no limitation as to their locations other than as claimed is intended or should be inferred. Furthermore, the buckle can have more than one LED and/or switch. If desired flashlight type mount of the LED can be used to provide a highly directional beam of light. As can be seen in FIG. 6 the circuit board 113 for controlling the light 111 is attached to the bottom surface 110b of the lid 110 in the depicted embodiment. The circuit board could be located in other locations as well. At least one battery 114 is placed in cavity 109 such that it contacts leads 115, 116 to create a complete circuit to provide power for the light 111. The remainder of the circuit between the battery and the light is not shown for clarity of the drawings.
Cavity 109 has ridge 117 extending across it to brace the external walls and to form a battery cavity 129 in the depicted embodiment. Switch 112 is a simple push button switch with flexible rubber cover in the depicted embodiment. Other types of switches could be used as well, including lever switches and other known types. The LED light has three modes in the depicted embodiment: on, off and flashing. Depressing the switch 112 changes the mode of the light 111. In the depicted embodiment the light modes are in the order of on, flashing, off and have to be cycled through in that order. Other designs of the switch and the mode are possible.
In the preferred embodiment the buckle is small enough to use as a buckle on a bracelet, as seen in FIG. 9. The buckle has a length X, a width W, a height to the top of the lid of Y and a height to top of the light of Z as seen in FIGS. 2 and 3. In the preferred embodiment the nominal dimensions are X=32 mm, W=22 mm, Y=9 mm, Z=14 mm. A larger version (not shown) has nominal dimensions of X=45 mm, W=30 mm with approximately the same Y and Z values.
As can be seen in FIGS. 10 and 11, in prior art side squeeze buckles 1 the female par 2 largely encloses the male part 4 with the female part 2 forming the top surface 3 of the buckle 1 when the parts are locked together. In the areas of the buckle when closed, the female part is the entire top surface of the buckle.
FIGS. 12 to 13 depict another embodiment of the buckle 200 where one of the attachment locations 206 is a hole, allowing a key ring or other device different from the flexible member 220 to be attached on the other attachment location 205. This allows the side squeeze buckle 200 to be used as a key fob or for other uses. As before, buckle 200 has a female receptacle section 201 and a male latch section 202. The male latch section 202 has a pair of arms 208 with tabs 203 on each side that engage holes 204 on the female 201 side to lock the buckle 200 together as described above. The button 212 and LED 211 are located as described above.
Referring next to FIGS. 14 and 15, another embodiment of the buckle 300 is shown. The side squeeze buckle 300 has a female receptacle section 301 and a male latch section 302 which function as described above. The male latch section 302 has a pair of arms 308 with tabs 303 on each side that engage holes 304 as before.
The male section 302 has a central section 307 extending from the attachment location 305 and flanked on two sides by arms 308 bearing tabs 303, as can be seen in FIG. 15. The two arms 308 are spaced apart from the central section 307 enough to allow the arms 308 to be flexed inward enough allow the buckle 300 to open as described above. The central section 307 has a cavity with a lid 310. In the current disclosure, the lid 310 and the top surface 325 of the central section 307, seen in FIGS. 14 and 15, form a large section of the top and bottom surface of the closed buckle. The female section 301 has two arms 318 extending around a central opening 320. The shape of the central opening 320 of the female section 301 corresponds to the shape of the central section 307 of the male section, forming an interlocked whole. The female section has a top surface 319 and a bottom surface 324. The bottom surface 324 of the closed buckle 300 is formed by the top surface of the lid 310 and the bottom surface 324 of the female section 301, as seen in FIG. 14. When the buckle is closed, the two sections interlock, such that the interlocked parts form the majority of the buckle. Lines C and D in FIG. 15 indicate end points of the male and female sections respectively in the closed buckle. In the embodiment 300, the cavity for the LED and electronics extends beyond the overlap into the part of the male section that is not overlapped by the female section when the buckle is closed, as seen in FIG. 14.
The male section 302 has a stabilizing member 321 extends from the front end 322 of the central section 307 of the male section 302. The stabilizing member 321 interlocks with the female section to stabilize the closed buckle in place, helping to prevent flexing of the closed buckle.
The top of the male section 302 has switch 312 integrated onto the top surface in the depicted embodiment. As can be seen in FIG. 15, the two LEDs 311a, 311b, extend outward from the male section on the side and behind the line D.
Referring next to FIGS. 16 and 17, another embodiment of the buckle 600 is shown. The side squeeze buckle 600 has a female receptacle section 601 and a male latch section 602 which function as described above. The male latch section 602 has a pair of arms 608 with tabs 603 on each side that engage holes 604 as before.
The male section 602 has a central section 607 extending from the attachment location 605 and flanked on two sides by arms 608 bearing tabs 603, as can be seen in FIG. 17. The two arms 608 are spaced apart from the central section 607 as described above. The central section 607 has a cavity with a lid 610. Lines E and F in FIG. 17 indicate end points of the male and female sections respectively in the closed buckle. In the embodiment 600, the cavity for the LED and electronics extends beyond the overlap into the part of the male section that is not overlapped by the female section when the buckle is closed, as seen in FIG. 16.
In this embodiment the switch 612 is on the side of the male section on the opposite side from the LED 611, as can be seen in FIG. 17. These are behind the line F and will be beyond the overlap area when the buckle 600 is closed.
Referring next to FIGS. 18 and 19, a third embodiment of the side squeeze buckle 400 has a female receptacle section 401 and a male latch section 402 which function identically to the buckles 100, 300 discussed above with respect to the interlocking of the two sections. The male latch section 402 has a pair of arms 408 with tabs 403 on each side that engage holes 404 on the female 401 side to lock the buckle 400 together. The buckle 400 is made from a substantially rigid material such as plastic that retains its shape but can be flexed enough to press the tabs 403 inward enough to disengage the tabs 403 from the holes 404 to allow the two sections to be pulled apart, as can be seen in FIG. 19. In the depicted embodiment, each section has an attachment location 405 and 406, which are single slots. Other known attachment locations could be used as well, including multiple slots for adjustable connections to straps, round holes or other known forms. No limitation is intended or inferred.
The male section 402 has a central section 407 extending from the attachment location 405 as described above. The central section 407 has a cavity (not shown) with a lid 410. In the current disclosure, the lid 410 and the bottom surface of the central section 420, seen in FIG. 18, form a large section of the top and bottom surface of the closed buckle. The two sections interlock as described above. The shape of the central opening 420 of the female section 401 corresponds to the shape of the central section 407 of the male section, forming an interlocked whole. The female section has a top surface 419 and a bottom surface (not shown). The top surface of the closed buckle 400 is formed by the top surface 410a of the lid and the top surface 419 of the female section 401.
The lid 410 has a switch 412 integrated onto the top surface 410a of the male section 402 in the depicted embodiment. The interior of the cavity, the lid and the rest of the workings of the LED are as discussed above. In this embodiment, the LED extends out of the side of the male section 401. At least one of the extending arms 418 of the female section has a recess 421 that fits around the LED 411, as seen in FIG. 19.
