Technical Field

[0001] The invention relates to a support for fixing other objects, in particular to an adjusting device for adjusting the position of other objects on a microphone stand, a musical instrument stand or a sound stand. Background Art

[0002] See also Fig.14 and Fig.15 As shown, a bracket in the prior art, such as a cymbal stand, has a cymbal connection end 91 and a plurality of adjustment bolts 92. Each adjustment bolt 92 corresponds to rotation or movement in one direction. For example, when the angle and height of the cymbal are to be adjusted at the same time, the adjustment bolts 92 corresponding to the rotation and vertical movement need to be loosened respectively, and then tightened after the adjustment is completed.

[0093] The following is a further description of the technical means adopted by the present invention to achieve the predetermined purpose of the invention with reference to the accompanying drawings and preferred embodiments of the present invention.

[0094] See also Figures 1 to 3 and Figure 8 As shown, the first embodiment of the bracket adjustment device 1 of the present invention is used to be assembled with a tripod 81 and an inclined rod 82 to form a bracket. The bracket can be a microphone stand, a musical instrument stand, a sound stand, or other brackets for fixing other objects. The adjustment device 1 includes a tripod connector 10, a connecting seat 20, a proximal clip 31, a distal clip 32, an inclined rod connecting tube 40, a tightening rod 51, and a manual operating member 52; and in this embodiment, it further includes a distal elastic member 61, a proximal elastic member 62, and a connecting tube elastic member 63.

[0095] The aforementioned tripod connector 10 is a cylinder and is used to connect the tripod 81. The tripod connector 10 also has a tripod positioning portion 11, which is formed around the outer annular surface of the tripod connector 10. The tripod positioning portion 11 in this embodiment includes a plurality of tripod positioning teeth, which are arranged around the outer annular surface of the tripod connector 10.

[0096] The aforementioned connecting base 20 can be rotatably mounted on the tripod positioning portion 11 of the tripod connecting member 10, so that the connecting base 20 can rotate relative to the tripod 81, which is the first degree of adjustment freedom of the present invention. The connecting base 20 has a first side 201 and a second side 202 opposite to each other. Specifically, a bottom circular groove 21 is formed on the bottom surface of the connecting base 20, and the connecting base 20 can rotatably mount the tripod positioning portion 11 through the bottom circular groove 21.

[0097] In this embodiment, the connection base 20 further has an expansion hole 22 and an expansion column 23. The expansion hole 22 is formed on the top surface of the connection base 20 and has an internal thread. The two opposite ends of the expansion column 23 are a fixed end 231 and an expansion end 232. The fixed end 231 is threaded with the expansion hole 22. The expansion end 232 protrudes from the connection base 20 and has an external thread. Thus, the user can connect other accessories to the top surface of the connection base 20 as needed, and can connect with the expansion hole 22 or the expansion column 23 according to the connector form of the accessory, thereby enhancing the functionality of the present invention and being compatible with accessories with external or internal threads.

[0098] The aforementioned proximal clip 31 can be detachably attached to the first side 201 of the connection base 20, and has an inner positioning portion 311 and a proximal positioning portion 312. The inner positioning portion 311 is formed on a side of the proximal clip 31 away from the connection base 20, and the proximal positioning portion 312 is located on a side of the proximal clip 31 facing the connection base 20. In this embodiment, the proximal positioning portion 312 includes a plurality of proximal positioning teeth, which are arranged along an arc.

[0099] The aforementioned proximal elastic member 62 is disposed between the connecting seat 20 and the proximal clip 31, and drives the connecting seat 20 and the proximal clip 31 to move away from each other. Specifically, the proximal elastic member 62 is a compression spring.

[0100] The aforementioned distal clip 32 can be detachably attached to the second side 202 of the connection base 20, and has a distal positioning portion 321, which is formed on the side of the distal clip 32 facing the connection base 20. The distal positioning portion 321 includes a plurality of distal positioning teeth arranged along an arc in this embodiment.

[0101] The distal elastic member 61 is disposed between the connecting seat 20 and the distal clip 32, and drives the connecting seat 20 and the distal clip 32 to move away from each other. Specifically, the distal elastic member 61 is a compression spring.

[0102] The aforementioned inclined rod connecting tube 40 can be detachably attached to the proximal clip 31, and can rotate relative to the connecting seat 20, and this rotation is usually a rotation on a vertical plane. The rotation axes of the inclined rod connecting tube 40 and the connecting seat 20 and the rotation axes of the connecting seat 20 and the tripod connecting member 10 are not parallel, and specifically, the rotation axes of the inclined rod connecting tube 40 and the connecting seat 20 and the rotation axes of the connecting seat 20 and the tripod connecting member 10 are perpendicular to each other. The inclined rod connecting tube 40 has two outer clamping holes 41 and an outer positioning portion 42, and the two outer clamping holes 41 are respectively formed on opposite sides of the inclined rod connecting tube 40, and the outer positioning portion 42 is located on the side of the inclined rod connecting tube 40 facing the connecting seat 20, and can be detachably engaged with the inner positioning portion 311 of the proximal clip 31.

[0103] Please refer to Figures 3 to 5 As shown, the aforementioned clamping rod 51 can slide through the inclined rod connecting tube 40, the proximal clip 31, the connecting seat 20 and the distal clip 32 in sequence, and the inclined rod connecting tube 40 can rotate relative to the connecting seat 20, which is the second degree of adjustment freedom of the present invention. The clamping rod 51 has a first end 511, a second end 512, a clamping abutment 513 and an inner clamping hole 514. The clamping abutment 513 is formed at the first end 511 and can be relatively movably located in the inclined rod connecting tube 40. The inner clamping hole 514 penetrates the clamping abutment 513. The aforementioned inclined rod 82 can slide straightly through the two outer clamping holes 41 of the inclined rod connecting tube 40 and the inner clamping hole 514 of the clamping rod 51. The inclined rod 82 can slide straightly relative to the inclined rod connecting tube 40, which is the third degree of adjustment freedom of the present invention.

[0104] In this embodiment, the outer contour of the clamping and abutting portion 513 is non-circular, and specifically, is in a racetrack shape, and the inner wall surface of the inclined rod connecting tube 40 corresponds to the outer contour of the clamping and abutting portion 513 and is also in a racetrack shape, so that the clamping rod 51 cannot rotate relative to the inclined rod connecting tube 40. Therefore, when the inclined rod 82 is not inserted, the openings of the outer clamping hole 41 and the inner clamping hole 514 can still be roughly aligned, and the inclined rod 82 can be easily inserted.

[0105] Specifically, the inclined rod connecting tube 40 has an end wall 43 and an annular wall 44. The outer positioning portion 42 is formed on the end wall 43 of the inclined rod connecting tube 40 and is located on the side of the inclined rod connecting tube 40 facing the connecting seat 20. The annular wall 44 surrounds the outside of the tightening abutment portion 513 of the tightening rod 51, and the two outer clamping holes 41 penetrate the annular wall 44 and are respectively located on opposite sides of the annular wall 44. The inclined rod 82 straightly penetrates the two outer clamping holes 41 and the inner clamping hole 514 of the tightening rod 51.

[0106] The manual operating member 52 is connected to the second end 512 of the clamping rod 51 and has a manual abutment portion 521. The manual abutment portion 521 can move toward or away from the clamping abutment portion 513 of the clamping rod 51. The manual operating member 52 is a hand-locking bolt in this embodiment. The manual abutment portion 521 is one end of the manual operating member 52 facing the clamping abutment portion 513. The manual operating member 52 is sleeved and screwed with the second end 512 of the clamping rod 51. Therefore, the position of the manual abutment portion 521 can be changed by rotating the manual operating member 52. In other preferred embodiments, the manual operating member 52 can also be a quick-release handle that uses a cam structure to change the position of the manual abutment portion 521.

[0107] The aforementioned connecting tube elastic member 63 is disposed between the inclined rod connecting tube 40 and the proximal clip 31, and drives the inclined rod connecting tube 40 and the proximal clip 31 to move away from each other. Specifically, the connecting tube elastic member 63 is a compression spring.

[0108] Please refer to Figures 5 to 7 As shown, the manual abutment portion 521 of the manual operating member 52 can move toward the direction close to the clamping abutment portion 513 of the clamping rod 51, and then clamp the oblique rod connecting tube 40, the proximal clamping piece 31, the connecting seat 20 and the distal clamping piece 32 together with the clamping abutment portion 513 to form a locked state, so as to simultaneously limit the above-mentioned three degrees of freedom of adjustment:

[0109] First, the hole wall of the inner clamping hole 514 of the tightening rod 51 clamps the inclined rod 82 in opposite directions relative to the hole walls of the two outer clamping holes 41 of the inclined rod connecting tube 40 , and the inclined rod 82 cannot slide relative to the inclined rod connecting tube 40 .

[0110] Second, the outer positioning portion 42 of the inclined rod connecting tube 40 is engaged with the inner positioning portion 311 of the proximal clip 31 , so that the inclined rod connecting tube 40 cannot rotate relative to the connecting seat 20 .

[0111] Third, the proximal positioning portion 312 of the proximal clip 31 and the distal positioning portion 321 of the distal clip 32 are clamped tightly against the tripod positioning portion 11 of the tripod connector 10 , so that the connecting base 20 cannot rotate relative to the tripod connector 10 .

[0112] When the present invention is used, an audio device or musical instrument, such as a microphone (not shown), is installed on one end of the inclined rod 82 , and then the manual operating member 52 is loosened.

[0113] Please refer to Figures 7 to 11 As shown, the inclined rod connecting tube 40, the connecting seat 20, the proximal clip 31 and the distal clip 32 are pushed away from each other by the distal elastic member 61, the proximal elastic member 62 and the connecting tube elastic member 63 (as shown in FIG. Figure 7 The inclined rod 82 can rotate relative to the connecting seat 20 about the center line of the clamping rod 51, and can slide linearly relative to the inclined rod connecting tube 40 and the clamping rod 51 (as shown). Figure 8 and Fig. 9 As shown), the connecting seat 20 can rotate relative to the tripod 81 (as shown Fig.10 and Fig.11 As shown in FIG. 1 , the inclined rod 82 has two degrees of rotational freedom and one degree of movement freedom, and the user can adjust the posture of the inclined rod 82 in three directions at the same time, so as to adjust the position of the microphone to suit users of different body shapes or various objects to be collected.

[0114] After the adjustment is completed, the manual operating member 52 is tightened to put the present invention in a locked state to fix the microphone at the adjusted position.

[0115] This embodiment further has the following structures and advantages:

[0116] First, the outer positioning portion 42 of the inclined rod connecting tube 40 includes a plurality of outer positioning teeth, which are arranged around the clamping rod 51. The inner positioning portion 311 of the proximal clip 31 includes a plurality of inner positioning teeth, which are arranged around the clamping rod 51, so that the outer positioning portion 42 can be firmly engaged with the inner positioning portion 311.

[0117] Second, the proximal positioning portion 312 of the proximal clip 31, the distal positioning portion 321 of the distal clip 32, and the tripod positioning portion 11 of the tripod connector 10 all include a plurality of positioning teeth. Therefore, in the locked state, the proximal positioning portion 312 and the distal positioning portion 321 can be firmly engaged with the tripod positioning portion 11 to ensure that the connecting base 20 cannot rotate relative to the tripod connector 10. However, the present invention is not limited to this. The proximal positioning portion 312, the distal positioning portion 321, and the tripod positioning portion 11 can also be made of materials with a higher friction coefficient such as rubber, so that the friction force is used to prevent the connecting base 20 from rotating relative to the tripod connector 10.

[0118] Third, by setting the distal elastic member 61, the proximal elastic member 62 and the connecting tube elastic member 63, when the manual abutment portion 521 of the manual operating member 52 can move in the direction away from the clamping abutment portion 513 of the clamping rod 51, the elastic member can drive the components away from each other to ensure that the positioning teeth will not engage with each other, thereby facilitating the adjustment of the position of the inclined rod 82.

[0119] See also Fig.12 As shown, the second embodiment of the present invention is substantially the same as the first embodiment, except that the second embodiment omits the proximal clip 31, and the inner positioning portion 311 originally formed on the proximal clip 31 is changed to be formed on the first side of the connecting seat 20A. The manual abutment portion of the manual operating member 52A can clamp the inclined rod connecting tube 40A, the connecting seat 20A and the distal clip 32A together with the clamping abutment portion of the clamping rod 51A to form a locked state.

[0120] In the locked state, the outer positioning portion of the inclined rod connecting tube 40A engages with the inner positioning portion of the connecting seat 20A, so that the inclined rod connecting tube 40A cannot rotate relative to the connecting seat 20A. At the same time, the inner wall surface of the connecting seat 20A and the distal positioning portion of the distal clip 32A are clamped tightly against the tripod positioning portion of the tripod connecting member, so that the connecting seat 20A cannot rotate relative to the tripod connecting member.

[0121] See also Fig.13 As shown, the third embodiment of the present invention is substantially the same as the first embodiment, except that the third embodiment omits the distal clamping piece 32. The manual abutment portion of the manual operating member 52B can clamp the inclined rod connecting tube 40B, the proximal clamping piece 31B and the connecting seat 20B together with the clamping abutment portion of the clamping rod 51B to form a locked state.

[0122] In the locked state, the proximal positioning portion of the proximal clip 31B and the inner wall surface of the connecting seat 20B are clamped tightly against the tripod positioning portion of the tripod connecting member, so that the connecting seat 20B cannot rotate relative to the tripod connecting member.

[0123] In summary, the present invention connects the manual operating member 52 after the clamping rod 51 passes through the inclined rod connecting tube 40, the distal clip 32 and the connecting seat 20. The user can operate the manual operating member 52 to make all corresponding positioning parts on the inclined rod connecting tube 40, the distal clip 32, the connecting seat 20 and the tripod connecting member 10 abut or separate from each other at the same time, and then the posture can be adjusted in three directions at the same time through the manual operating member 52, which is more convenient to use.

[0124] The above is only a preferred embodiment of the present invention and does not limit the present invention in any form.
