Description

[Technical Field]

[0001] This invention relates to a support frame structure for musical instruments, and in particular to a bongo drum support frame. [Previous Technology]

[0002] The bongo drum support frame provided in US Patent No. 7468480 mainly consists of a support rod welded to the end of the connecting rod on both opposite sides of the frame, which can support the drum body of the bongo drum respectively, and thereby the bongo drum assembly consisting of two drum bodies connected together can be placed on the support frame.

[0003] However, the previous patent only uses an L-shaped clamp to abut against the back of the crossbeam between the two drum bodies in one direction, and its positioning effect is not ideal. Therefore, when the user hits the drum surface, the bongo drum formed by the connection of the two drum bodies will still slide forward or to the left or right. Furthermore, the support rod provided by the previous patent cannot adjust the clamping function according to different sizes of bongo drums, and still has its shortcomings.

[0004] Furthermore, the connecting rod of the prior art is made of a flat iron, and the end of the connecting rod is directly twisted in the direction of its axis to form an overlapping surface for the support rod to overlap. However, the structural strength of the flat iron will be greatly reduced after twisting, resulting in insufficient support strength at the joint between the connecting rod and the support rod. This causes the drumhead to wobble easily when the user applies downward force to strike it, resulting in poor support stability. Moreover, the way the support rod is directly welded to the connecting rod in the prior art also makes it impossible for the user to use different lengths of support rods to accommodate different sizes of bongo drums. Therefore, the bongo drum support frame provided by the prior art still needs improvement.

[0005] In view of this, how to improve the above-mentioned problems is the primary issue that the present invention aims to solve. [Summary of the Invention]

[0006] The main objective of this invention is to provide a bongo drum support frame that can be quickly adjusted according to different sizes of bongo drums, while ensuring that bongo drums of different sizes can be stably positioned and not easily slip.

[0007] To achieve the aforementioned objective, the present invention provides a bango drum support frame, comprising a vertical rod having an upper end and a lower end. A first connecting rod is pivotally mounted on each of the two opposite sides of the upper end. A knob and a sliding sleeve are sequentially arranged from bottom to top on the lower end. The knob is screwed to the lower end. By rotating the knob, the sliding sleeve can be pushed against each other and moved axially along the vertical rod. A second connecting rod is pivotally mounted on each of the two opposite sides of the sliding sleeve, and each second connecting rod extends upward and is pivotally connected to each of the first connecting rods. Each of the first connecting rods has a pivot end and an assembly end opposite to the pivot end. Each first connecting rod is pivotally connected to the two opposite sides of the upper end with its pivot end. Each assembly end of the first connecting rod is connected to a support rod that intersects the first connecting rod perpendicularly and extends in a forward direction and a rearward direction. The feature is that:

[0008] The support rod is provided with an adjustment group at at least one end. The adjustment group includes a sleeve provided on the support rod, and a limiting member that can be adjusted and moved and positioned on the sleeve is provided on the outer peripheral surface of the sleeve. The limiting member protrudes radially to form a flange portion, and the flange portion forms a clamping surface on the side facing the first connecting rod.

[0009] The above-mentioned objects and advantages of the present invention can be readily understood from the following detailed description of the selected embodiments and the accompanying drawings.

Implementation Method

[0010] Please refer to Figures 1-3, which show a first embodiment of the bongo drum support frame provided by the present invention. It has a vertically oriented upright rod 11 with an upper end 12 and a lower end 13. A first connecting rod 21 is pivotally mounted on each of the two opposite sides of the upper end 12. A knob 31 and a sliding sleeve 41 are sequentially arranged from bottom to top on the lower end 13. The knob 31 is screwed onto an externally threaded section 131 of the lower end 13, and the sliding sleeve 41 is slidably fitted onto the lower end 13. The outer periphery of the sliding sleeve 41 is in contact with the upward-facing push portion 32 of the knob 31. A second connecting rod 51 is pivotally mounted on each of the two opposite sides of the sliding sleeve 41. Each of the second connecting rods 51 extends upward and is pivotally connected to each of the first connecting rods 21. When the user rotates the knob 31 to move along the external thread section 131, the sliding sleeve 41 can be pushed to move along the axial direction of the upright rod 11. This allows each of the second connecting rods 51 mounted on the sliding sleeve 41 to drive each of the first connecting rods 21 to perform a pivoting motion.

[0011] Furthermore, each of the first connecting rods 21 has a flat, plate-shaped rod body 22, and a pivot end 23 and an assembly end 24 opposite to the pivot end 23 are formed at both ends of the rod body 22. Each of the first connecting rods 21 is pivotally connected to the two opposite sides of the upper end 12 with its pivot end 23. The assembly end 24 of each of the first connecting rods 21 is folded back into a U-shape towards its pivot end 23 and sequentially has a first bend segment 241 that is generally perpendicular to the rod body 22 and a second bend segment 242 that is generally parallel to the rod body 22. Symmetrically arranged through holes 25 are opened on the second bend segment 242 and the rod body 22 opposite to the second bend segment 242. A support rod 61 is simultaneously inserted through the second bend segment 242. The bending section 242 and the through hole 25 of the rod body 22 allow the support rod 61 to extend perpendicularly to each of the first connecting rods 21 in a forward and a rearward direction. A locking fastener 62 passes through the first bending section 241 and is screwed into one of the screw holes 611 of the support rod 61, so that the support rod 61 can be detachably attached to the first connecting rod 21. The support rod 61 has an adjustment group 63 at its forward end. The adjustment group 63 has a sleeve 64 fitted on the support rod 61. A limiting member 65 that can be adjusted and positioned on the sleeve 64 is attached to the outer circumferential surface of the sleeve 64. The limiting member 65 protrudes radially to form a flange portion 651, and the flange portion 651 forms a clamping surface 652 on the side facing the first connecting rod 21.

[0012] In this first embodiment, the sleeve 64 has a recessed hole 641 at one end along its axial direction, and a mating surface 642 at the other end. The sleeve 64 is fitted onto the support rod 61 with its hole 641 and abuts against the end of the support rod 61 with its mating surface 642. A through hole 643 is provided on the mating surface 642 of the sleeve 64. Another screw hole 612 is provided at the end of the support rod 61 at a position opposite to the through hole 643, and a screw 66 is locked from the outside through the through hole 643 into the screw hole 612, so that the sleeve 64 can be positioned on the support rod 61. An external thread section 644 is provided on the outer circumferential surface of the sleeve 64, and the limiting member 65 is annular with an inner circumferential surface. An internal thread section 67 is provided on the inner circumferential surface of the sleeve 64. The limiting member 65 is screwed onto the external thread section 644 of the sleeve 64 with its internal thread section 67, so that the limiting member 65 can be adjusted and moved along the axial direction of the sleeve 64. The external thread section 644 of the sleeve 64 has a support side 645 that is flattened into a plane along its upward top side. The screw 66 has a threaded part 661 and a head 662 with an outer diameter larger than that of the threaded part 661. The screw 66 is locked into the screw hole 612 with its threaded part 661. A liner 68 is provided between the head 662 of the screw 66 and the abutment surface 642 of the sleeve 64. The outer diameter of the liner 68 is larger than that of the sleeve 64 to prevent the limiting member 65 from coming off the sleeve 64 when adjusting its screwed position.

[0013] Furthermore, a support block 14 is fixedly provided at the upper end 12 of the upright rod 11. The support block 14 has a front side 141 and a rear side 142. A set of openings 15 are provided on the front side 141, and a forward-protruding insert rod 16 is connected to the set of openings 15. A longitudinal groove 17 is provided on the rear side 142, and an L-shaped clamping member 71 is connected to the longitudinal groove 17. The L-shaped clamping member 71 has an upright section 72 and a pressing section 73 that is perpendicular to the upright section 72 and protrudes towards the front side 141. An L-shaped sleeve 74 extending to the upright section 72 is fitted onto the abutment section 73. The L-shaped sleeve 74 is also made of soft material and has a cushioning and shock absorption function. A longitudinal elongated hole 721 is opened on the upright section 72. The L-shaped clamping member 71 is accommodated in the longitudinal slide groove 17 with its upright section 72 facing each other. Several locking fasteners 75 pass through the longitudinal elongated hole 721 to lock the upright section 72 in the longitudinal slide groove 17. The L-shaped clamping member 71 can change its locking position through the longitudinal elongated hole 721, thereby adjusting the clamping height of the L-shaped clamping member 71.

[0014] Next, please refer to Figures 4 and 5. In practical use, after the plug rod 16 is inserted into the connecting seat 82 of a stand 81, the two drum bodies 83 and 84 of the bongo drum are placed on the two first connecting rods 21 and their support rods 61 respectively. The pressing section 73 of the L-shaped clamping member 71 presses against the crossbeam 85 of the bongo drum that connects the two drum bodies 83 and 84. Then, according to the size of the drum bodies 83 and 84, the screw position of the limiting member 65 on the support rod 61 is adjusted by hand rotation, so that the clamping surface 652 on the flange portion 651 of the limiting member 65 is adjusted. By clamping the drum bodies 83 and 84 onto the forward-facing side, the L-shaped clamp 71 and the limiting member 65 can securely position the two drum bodies onto the support rod 61. This allows the bongo drum support frame provided by the present invention to be quickly adjustable and to ensure that bongo drums of different sizes can be securely positioned without slipping. Furthermore, by rotating the knob 31, the user can drive the second connecting rod 51 to push the first connecting rod 21 to produce a corresponding pivoting action, thereby simultaneously moving the bongo drum up and down to adjust its height to accommodate the different drummers' playing habits.

[0015] Furthermore, the present invention further improves the structural strength of the assembly ends 24 of each of the first connecting rods 21 by integrally bending them into a U-shape towards their pivot ends 23. This structure not only provides better structural strength to the assembly ends 24, but also allows the support rod 61 to be simultaneously supported by the shaft 22 of the first connecting rod 21 and the second bending section 242, thus providing better support. This effectively reduces the shaking caused by the drummer during striking, providing better support. The support stability is improved; furthermore, the support rod 61 of the present invention is directly inserted into the assembly end 24 and then locked to the first connecting rod 21 by the fastener 62. Therefore, the user can simply unscrew the fastener 62 to remove the support rod 61 from the first connecting rod 21. This further provides the user with the ability to easily and quickly replace the support rod 61 of different lengths and adjust the clamping height of the L-shaped clamp 71, so that the bongo drum support frame constructed by the present invention can be used for bongo drums of various sizes.

[0016] As shown in Figure 6, in practical applications, the present invention can also be fitted with symmetrically arranged adjustment groups 63 on both ends of each of the support rods 61, thereby ensuring the stability of the assembly of the two drum bodies by means of the front and rear clamping of their limiting members 65.

[0017] Next, please refer to Figure 7, which shows the second embodiment of the bango drum support frame provided by the present invention. The difference between this second embodiment and the first embodiment is only that the adjustment group 63 is composed of another sleeve 91 and another limiting member 92. In this second embodiment, the outer peripheral surface of the sleeve 91 is smooth, and the limiting member 92 is composed of a C-shaped binding ring wrapped around the outer peripheral surface of the sleeve 91. The limiting member 92 has an opening 921, and two sets of parts are formed at intervals on both ends of the opening 921. 922, and by locking the two sets of parts 922 with a fastener 93, the limiting member 92 can be locked and positioned on the sleeve 91 in a coiling manner. When the fastener 93 has not yet locked the two sets of parts 922, the limiting member 92 can slide along the outer circumferential surface of the sleeve 91 to adjust its locking position. This also has the effect of quickly adjusting its locking position according to different sizes of bongo drums. Similarly, by clamping the limiting members 92 on the front side of the bongo drum respectively, it also has the effect of providing a stable positioning of the bongo drum.

[0018] However, the above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Any substitution of equivalent elements should still fall within the scope of the present invention.

[0019] In summary, this invention enables those skilled in the art to understand that it can indeed achieve the aforementioned objectives and complies with the provisions of the Patent Law. Therefore, this application is filed in accordance with the law. [Simplified Explanation of the Diagram]
