Description

TECHNICAL FIELD

[0001] The present invention relates to a stand for fixing another object, in particular a microphone stand. BACKGROUND

[0002] In order to ensure that the center of gravity remains stable after a microphone is placed on the top end, the bottom of the microphone stand must be provided with a large area and a considerable weight of the base to prevent the microphone stand from falling due to unstable center of gravity. However, when the microphone stand is stored, the base will also occupy a large amount of floor space, making storage very inconvenient. Although the existing microphone stand can also be stored in a horizontal lying posture to reduce the occupied space, the length of the microphone stand is very long and the weight is heavy when lying horizontally, and the center of gravity is concentrated at one end of the base. Therefore, it is very difficult to store the microphone stand on a shelf in a horizontal lying posture, and in practice, the microphone stand can only be laid horizontally on the ground, which not only makes storage troublesome but also easily causes damage to the appearance.

[0003] Therefore, the microphone stand of the prior art needs to be improved. SUMMARY

[0080] The technical means adopted by the present application to achieve the predetermined object of the application are further explained in the following in cooperation with the drawings and the preferred embodiments of the present application.

[0081] Please refer to the drawings, wherein Figure 1 , Figure 2 , Figure 5 and Figure 14 , the folding stand of the present application comprises a base plate 10, a stand 20 and a switching mechanism 30. The folding stand is preferably a microphone stand.

[0082] The aforementioned base plate 10 is used to be placed on the ground, and one side of the base plate 10 is formed with a standing storage surface 11. The aforementioned stand 20 is located on the base plate 10.

[0083] The aforementioned switching mechanism 30 is arranged between the base 10 and the stand 20. The switching mechanism 30 has a locking state and a releasing state. In the locking state, the switching mechanism 30 prevents the stand 20 from being turned relative to the base 10. Specifically, in the locking state, the switching mechanism 30 fixes the stand 20 in an upright position (as shown in Figure 5 Fig. 1), in which the stand 20 is substantially perpendicular to the base 10 and can be used as a general microphone stand.

[0084] In the releasing state, the switching mechanism 30 allows the stand 20 to be turned relative to the base 10 to a storage position (as shown in Figure 14 Fig. 2), in which the stand 20 is substantially in the same plane as the base 10 and the whole device is flat and easy to store. The switching mechanism 30 is switched between the locking state and the releasing state by the stand 20. When the stand 20 is turned about its own axis relative to the base 10 and is moved up and down, the switching mechanism 30 is driven by the stand 20 to switch from the locking state to the releasing state. In the present embodiment, the switching mechanism 30 allows the stand 20 to be turned relative to the base 10 by more than 80 degrees to the storage position, but the present application does not limit the angle of the stand 20 relative to the base 10.

[0085] Please refer to Figures 2 to 4 and Figure 8 , the switching mechanism 30 has a fixing seat 31, a control member 32, a rising elastic member 33, a first turning positioning member 34, a second turning positioning member 35, at least one upright positioning member 36, and at least one storage positioning member 37. The fixing seat 31 is arranged on the base 10, and the fixing seat 31 forms a turning groove 41, a first locking groove 42, and a second locking groove 43. Specifically, the fixing seat 31 is assembled by a structural member 311 and a lower cover 312.

[0086] Please refer to Figure 4 , Figure 7 and Figure 8 , the turning groove 41 is concavely arranged on the top surface of the fixing seat 31. The turning groove 41 is elongated, and its opposite ends are an outer end and an inner end, respectively. The outer end forms a storage fixing opening 411 on one side surface of the fixing seat 31. In the present embodiment, the inner end of the turning groove 41 extends downward to form a descending section 412, that is, the turning groove 41 of the present embodiment is substantially L-shaped, and the turning groove 41 includes a transverse section 413 extending from the inner end to the outer end, and the descending section 412 connected to the transverse section 413.

[0087] The turnover groove 41 has two turnover side walls 414, a main fixed wall 415 and an auxiliary fixed wall 416. The two turnover side walls 414 are oppositely arranged, and the two turnover side walls 414 are specifically two groove walls of the horizontal section 413. The main fixed wall 415 is located at the inner end of the turnover groove 41 and faces the receiving fixed port 411. The groove wall of the descending section 412 facing the receiving fixed port 411 also belongs to the main fixed wall 415. The auxiliary fixed wall 416 is located in the descending section 412 and faces the main fixed wall 415; that is, the auxiliary fixed wall 416 and the main fixed wall 415 are opposite to each other.

[0088] The first locking groove 42 is recessed in the turnover groove 41 and has a first surrounding section 421 and a first ascending section 422. The first surrounding section 421 is recessed in the main fixed wall 415 of the turnover groove 41 and extends to one of the turnover side walls 414 around the descending section 412 of the turnover groove 41. The height position of the first surrounding section 421 corresponds to the descending section 412, that is, the first surrounding section 421 is located lower than the horizontal section 413. One end of the first surrounding section 421 located at the main fixed wall 415 is a first locking end 4211.

[0089] One end of the first ascending section 422 is connected to one end of the first surrounding section 421 located at the turnover side wall 414, and the other end extends upward to form a first release end 4221.

[0090] The second locking groove 43 is recessed in the turnover groove 41 and is opposite to the first locking groove 42; specifically, the second locking groove 43 is rotationally symmetrical to the first locking groove 42. The second locking groove 43 has a second surrounding section 431 and a second ascending section 432.

[0091] The second surrounding section 431 is opposite to the first surrounding section 421 of the first locking groove 42. The second surrounding section 431 is recessed in the auxiliary fixed wall 416 of the turnover groove 41 and extends to the other turnover side wall 414 around the descending section 412 of the turnover groove 41. The height position of the second surrounding section 431 corresponds to the descending section 412, that is, the second surrounding section 431 is located lower than the horizontal section 413. One end of the second surrounding section 431 located at the auxiliary fixed wall 416 is a second locking end 4311.

[0092] The second ascending section 432 is opposite to the first ascending section 422 of the first locking groove 42. One end of the second ascending section 432 is connected to one end of the second surrounding section 431 located at the other turnover side wall 414, and the other end extends upward to form a second release end 4321.

[0093] The control member 32 is disposed at the lower end of the stand 20, and is particularly fixed. The control member 32 is disposed through the inner end of the turning groove 41 of the fixing seat 31, and the control member 32 protrudes a first turning shaft 321 and a second turning shaft 322 thereon, which are oppositely disposed on the control member 32. The first turning shaft 321 and the second turning shaft 322 are blocks with turning shaft functions. The first turning shaft 321 is slidably disposed through the first locking groove 42 of the fixing seat 31, and the second turning shaft 322 is slidably disposed through the second locking groove 43 of the fixing seat 31. The positions of the first turning shaft 321 and the second turning shaft 322 of the control member 32 change with the rotation and the up-and-down movement of the stand 20, so as to make the switching mechanism 30 switch from the locked state (as shown in Figure 4 、 Figure 7 and Figure 8 to the released state (as shown in Figure 12 ).

[0094] The aforementioned up elastic member 33 is disposed at the descending section 412 of the turning groove 41, and pushes the control member 32 upward to make the control member 32 tend to move upward. Particularly, the up elastic member 33 is a compression coil spring, and the diameter of the up elastic member 33 tapers from one end to the other end to form a conical shape. When the up elastic member 33 is compressed, the conical up elastic member 33 can be compressed into a flat disc shape, which is more space-saving than a cylindrical compression spring, and can effectively reduce the thickness of the chassis 10.

[0095] Please refer to Figure 4 、 Figure 7 and Figure 8 for the locked state, the first turning shaft 321 is located at the first locking end 4211 of the first locking groove 42, and the second turning shaft 322 is located at the second locking end 4311 of the second locking groove 43, so as to fix the stand 20 at the upright position. Particularly, in the locked state, the first turning shaft 321 and the second turning shaft 322 jointly form a long shaft extending along the length direction of the transverse section 413 of the turning groove 41, and the two ends of the long shaft are respectively inserted into the opposite groove walls of the first locking groove 42, so that the control member 32 can only rotate about the connecting line of the first turning shaft 321 and the second turning shaft 322; however, at this time, the control member 32 is clamped by the two turning side walls 414 and cannot rotate about the aforementioned connecting line, so that the control member 32 cannot rotate at all in the locked state, and thus the stand 20 is fixed at the upright position in the locked state.

[0096] Please refer to Figure 4 、 Figure 6 and Figure 7As shown, the aforementioned at least one vertical positioning member 36 is preferably two, which are arranged on the fixing base 31 and tend to penetrate into the inner end of the overturning groove 41. The vertical positioning member 36 is specifically a resilient stopper integrally formed on the fixing base 31. When the stand bar 20 is in the vertical position, the two vertical positioning members 36 penetrate into the inner end of the overturning groove 41 and abut against the outer circumferential surface of the stand bar 20 to limit the stand bar 20 in the vertical position.

[0097] As shown in Figure 7 and Figure 13 , the aforementioned first rotation positioning member 34 is arranged on the lower cover 312 of the fixing base 31 and tends to penetrate into the first locking groove 42 and abut against the first overturning shaft 321 of the control member 32 to limit the first overturning shaft 321 in the first locking end 4211. The aforementioned second rotation positioning member 35 is arranged on the lower cover 312 of the fixing base 31 and tends to penetrate into the second locking groove 43 and abut against the second overturning shaft 322 of the control member 32 to limit the second overturning shaft 322 in the second locking end 4311 (as shown in Figure 13 ). The first rotation positioning member 34 and the second rotation positioning member 35 are specifically metal balls, which are pushed upward by springs and tend to penetrate into the corresponding locking grooves.

[0098] As shown in Figures 7 to 11 , to switch the switching mechanism 30 from the locked state (as shown in Figure 7 and Figure 8 ) to the released state (as shown in Figure 11 ), the stand bar 20 is first rotated about its axis relative to the base 10. At this time, the control member 32 is rotated with the stand bar 20, so that the first overturning shaft 321 moves from the first locking end 4211 to the connection between the first circumferential segment 421 and the first ascending segment 422 (as shown in Figure 9 and Figure 10 ), and the second overturning shaft 322 also moves from the second locking end 4311 to the connection between the second circumferential segment 431 and the second ascending segment 432.

[0099] Then, the control member 32 is pushed upward by the ascending resilient member 33 and moves upward, so that the first overturning shaft 321 automatically slides along the first ascending segment 422 to the first released end 4221, and the second overturning shaft 322 automatically slides along the second ascending segment 432 to the second released end 4321 (as shown in Figure 8 ). At this time, the switching mechanism 30 has been switched to the released state.

[0100] As shown in Figure 11 and Figure 12As shown, in the released state, the first turning shaft 321 is located at the first releasing end 4221 of the first locking slot 42, and the second turning shaft 322 is located at the second releasing end 4321 of the second locking slot 43, so that the stand 20 can be turned about the line connecting the first turning shaft 321 and the second turning shaft 322.

[0101] Specifically, in the released state, the first turning shaft 321 and the second turning shaft 322 jointly form a long axis perpendicular to the horizontal section 413, so that the control member 32 can be turned about the line connecting the first turning shaft 321 and the second turning shaft 322, and at this time, the slot wall of the turning slot 41 does not prevent the control member 32 from turning, thereby enabling the stand 20 to be turned about the line connecting the first turning shaft 321 and the second turning shaft 322 by more than 80 degrees to the storage position.

[0102] In the present embodiment, the stand 20 can be turned about the line connecting the first turning shaft 321 and the second turning shaft 322 by 90 degrees to the storage position, and when the stand 20 is located at the storage position, the stand 20 is laid horizontally through the turning slot 41 and the storage fixing opening 411 of the turning slot 41.

[0103] Please refer to Figure 4 , Figure 14 and Figure 15 As shown, the number of the at least one storage positioning member 37 is specifically two, and the two storage positioning members 37 are arranged at opposite positions of the outer end of the turning slot 41 of the fixed seat 31 and tend to penetrate into the outer end of the turning slot 41. When the stand 20 is located at the storage position, the two storage positioning members 37 penetrate into the outer end of the turning slot 41 and abut against the stand 20 to limit the stand 20 to the storage position.

[0104] The folding stand of the present embodiment has a storage state, and the so-called storage state means that when the stand 20 is located at the storage position, the extension line of the axis of the stand 20 passes through the standing storage surface 11 of the base plate 10, so that the folding stand can be placed on the ground with the standing storage surface 11 of the base plate 10 and stand upright on the ground without external force assistance, thereby greatly saving the space required for storage.

[0105] The advantage of the present embodiment is that the inner end of the turning slot 41 extends downward to form a descending section 412, so that the slot wall of the descending section 412 can form an auxiliary fixing wall 416 and a second locking slot 43, thereby enabling the control member 32 to be provided with the second turning shaft 322 at the opposite position of the first turning shaft 321. In this way, the folding stand can obtain additional support of the second turning shaft 322 in the upright state to stabilize the upright state.

[0106] Please refer to Figure 16As shown, the second embodiment of the present application is substantially the same as the first embodiment, except that the inner end of the turning groove 41A does not extend downward to form the descending section 412, and therefore the fixing base 31A is only provided with the first locking groove 42A but not the second locking groove 43. The first locking groove 42A in this embodiment does not have the first ascending section 422, and is recessed in the main fixing wall 415A of the turning groove 41A and extends around to one of the turning side walls 414. Since the fixing base 31A does not have the second locking groove 43, the control member in this embodiment also does not have the second turning shaft.

[0107] Since the first locking groove 42A does not have the first ascending section 422, the control member 32 does not need to move up and down when the switching mechanism 30 is switched from the locked state to the released state, and only needs to rotate the vertical rod to change the state of the switching mechanism 30.

[0108] In summary, by providing the switching mechanism 30 between the base plate 10 and the vertical rod 20, the present application has the following advantages: first, the vertical rod 20 can be turned to the storage position relative to the base plate 10, so that the present application can be folded and stored, which can greatly reduce the floor space occupied by the base plate 10 and is very convenient to store. Second, the vertical rod 20 needs to be rotated after the switching mechanism 30 is switched from the locked state to the released state, which ensures that the vertical rod will not easily turn relative to the base plate. Third, since the state of the switching mechanism 30 is controlled by rotating the vertical rod 20, the user does not need to bend down when operating, which is very convenient to use.

[0109] The above description is only the preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with the preferred embodiment, it is not intended to limit the present application, and any skilled person in the art can make some changes or modifications to the above disclosed technical content to obtain equivalent embodiments with equivalent changes, as long as they do not deviate from the technical solution of the present application. Any simple modification, equivalent change and modification of the above embodiments based on the technical essence of the present application are still within the scope of the technical solution of the present application.
