DETAILED DESCRIPTION OF THE INVENTION

[0028] FIG. 1 shows a diving backplate according to a first preferred embodiment of the present invention. The diving backplate includes a device body 1, a first frame 2, a second frame 3 and multiple counterweights 4. The first frame 2 and the second frame 3 are connected to the device body 1, and each counterweight 4 is detachably mounted to the second frame 3.

[0029] Referring to FIGS. 1 and 3, the device body 1 may be configured to be worn on a user's back, and the device body 1 may be a backpack or a vest provided with air bladder(s) for diving. The device body 1 has an inward face 1a and an outward face 1b opposite to the inward face 1a. Specifically, the inward face 1a faces the user's back, and the outward face 1b faces away from the use's back.

[0030] The first frame 2 is connected to the outward face 1b of the device body 1, and the first frame 2 is configured to be mounted with an air tank (not shown). The first frame 2 may include multiple first position holes 21. In this embodiment, the first frame 2 includes two first position holes 21. Each of the first position holes 21 may be coupled with a positioning member P, so that the first frames 2 can be mounted to the device body 1. Besides, the first frame 2 may include multiple through holes 22 for decreasing the weight of the first frame 2.

[0031] Referring to FIGS. 1, 3 and 4, the first frame 2 may also include multiple adjusting holes 23. The adjusting holes 23 may be located aside from the first position holes 21 and the through holes 22. Preferably, the adjusting holes 23 may be located adjacently to the corners of the first frame 2. Each of the adjusting holes 23 may be mounted with an adjusting member 23A. One end of the adjusting member 23A may abut the outward face 1b of the device body 1, thereby keeping a distance D between the first frame 2 and the device body 1. A space formed with the distance D between the first frame 2 and the device body 1 is configured to receive other components completely or partially located therein. For example, said other components may include at least one air hose/breathing tube Q or other diving devices, and the present invention is not limited in this regard. The distance D is adjustable/changeable by adjusting the adjusting member 23A to prevent damage caused by compression force between the first frame 2 and the device body 1 to said other components.

[0032] Referring to FIGS. 1 and 3, the second frame 3 is connected to the inward face 1a of the device body 1. The second frame 3 may include a base 3a and two side walls 3b respectively connected to two sides of the base 3a. The base 3a and the two side walls 3b can be integrally connected, so that the structural strength of the second frame 3 can be enhanced. The second frame 3 may include multiple second positioning holes 31. The second positioning holes 31 may be located on the base 3a. The second positioning holes 31 may be configured to align with the first position holes 21 of the first frame 2, so that the positioning member P can extend through the device body 1 to be mounted with second positioning holes 31, and hence the second frame 3 can be mounted to the device body 1.

[0033] Referring to FIG. 1, the second frame 3 may include multiple first assembly holes 32 located on the two side walls 3b. Besides, the second frame 3 may include multiple through holes 33. The through holes 33 may be located on the base 3a, especially between the positioning holes 31, for decreasing the weight of the second frame 3.

[0034] Referring to FIGS. 1 and 2, the counterweights 4 are detachably mounted to the second frame 3. In this embodiment, two counterweights 4 are detachably mounted to the second frame 3. Each of the counterweights 4 may include a counterweight body 41 and multiple second assembly holes 42. The second assembly holes 42 may be configured to penetrate the counterweight body 41. Preferably, the second assembly holes 42 are configured to align with the first assembly holes 32 of the two side walls 3b. For each set of aligned second assembly holes 42 and the first assembly holes 32, a fastener F is provided to be mounted with the second assembly hole 42 and the first assembly hole 32, so that the counterweights 4 can be mounted to the second frame 3. Optionally, the quantity of the second assembly holes 42 may smaller than the quantity of the first assembly holes 32. In this respect, some of the first assembly holes 32 of the second frame 3 can be selected to be mounted with the second assembly holes 42 of each counterweight 4, so that the mounted positions of the counterweights 4 on the second frame 3 can be changed to different arrangements and/or mounted positions. For example, the counterweights 4 may be evenly arranged adjacent to the top end and the bottom end of the second frame 3, or biasedly arranged to one end of the second frame 3, so that the integral central weight of the overall diving backplate can be adjusted or even finely tuned by different mounted positions of the counterweights 4. Therefore, the diving backplate of this invention can be adapted for the users/divers with different heights to maintain their buoyancy center in a balance by making the overall buoyance center match or close the original buoyance center of the users when resurfacing, so that the users can easily sustain the necessary level or specific posture in the resurfacing condition.

[0035] Each counterweight 4 may include a third positioning hole 43 and a positioning plug 44. The third positioning hole 43 may be configured to be aligned with first position hole 21 and the second positioning hole 31. The positioning plug 44 may provide an internal threaded hole 441 for mounting with the positioning member P, and the positioning plug 44 may seals the third positioning hole 43, so that the positioning plug 44 prevents the positioning member P from generating a pushing force on the counterweight 4 toward the user's back and hence avoids uncomfortable feeling to the user's back. Also, the positioning plug 44 may include a recess 442 acting as a screw head recess or slot. The recess 442 may be provided away from the second frame 3 than the internal threaded hole 441. Preferably, the recess 442 forms a slot in a long and thin shape, so that a coin or a sheet piece or the like can insert into the recess 442 to rotate the positioning plug 44, thereby achieving the effect of convenient assembly and disassembly.

[0036] FIG. 5 shows a diving backplate according to a second preferred embodiment of the present invention which is substantially the same as the first preferred embodiment. In the second preferred embodiment, the diving backplate further includes a strap 5. The strap 5 may be made by PP (polypropylene) webbing or nylon webbing; however, the present invention is not limited in this regard. The strap 5 may install through multiple strap passages 45 provided on the counterweights 4. The strap 5 may form a handle strap portion 51 for the user directly carrying the overall diving backplate, and hence achieves the effect of convenient use/carrying. Specifically, the handle strap portion 51 and at least a part of the backplate form a closed loop shape for a user's hand to grab on. The strap 5 may further include a shoulder strap portion 52 and a waist strap portion 53. Specifically, the shoulder strap portion 52 and at least a part of the backplate form two closed loops respectively for the user's two arms to extend through and putting on the user's two shoulders. Specifically, the waist strap portion 53 and at least a part of the backplate optionally and operationally form a closed loop for embracing the user's waist. Preferably, the handle strap portion 51, the shoulder strap portion 52 and the waist strap portion 53 are integrally formed by a single strap, so that the structural strength of the strap 5 can be enhanced.

[0037] In summary, in the diving backplate according to the present invention, by the configuration that the multiple counterweights are detachably mounted to the second frame and the fasteners can be mounted with aligned second assembly holes and first assembly holes, the mounting positions of the counterweights can be changed/adjusted or finely tuned. Therefore, the diver can maintain their buoyancy center in a balance when resurfacing, so that the necessary level or specific posture of the diver can be sustained. Accordingly, the effect of improving using convenience can be achieved.
