Description

Technical Field

[0001] This utility model relates to a musical instrument stand, and more particularly to a foldable musical instrument stand for holding musical instruments such as electronic keyboards and speakers. Background Technology

[0002] Foldable instrument stands are widely popular as essential auxiliary equipment for music performances, teaching, and personal practice due to their portability and flexibility. These stands are typically made of lightweight metals or alloys and feature folding mechanisms, such as hinges or sliding components, allowing them to be easily folded into a smaller size for convenient carrying and storage when not in use. Their core function is to provide a stable and adjustable support platform for instruments of various sizes and types, ensuring playing comfort and safety.

[0003] CN221595949U discloses an adjustable musical instrument stand, the innovation of which lies in the addition of side clamping and fixing devices to the stand. This design uses the clamping devices on both sides to firmly fix musical instruments such as electronic keyboards to the stand, effectively preventing the instrument from shaking or slipping during performance and improving the stability of the performance. At the same time, the device can also evenly distribute the weight of the instrument, reduce the pressure concentration on the stand, and reduce the risk of deformation or damage.

[0004] Publication number CN205692558U focuses on improving the portability of electronic keyboard stands. The stand includes a foldable, cross-shaped first and second support frame, with casters on the lower side of the support frame. This innovation allows users to easily move the electronic keyboard by simply folding the stand and placing the casters on the ground, greatly facilitating the transportation and storage of the instrument.

[0005] Existing foldable instrument stands generally face a technical challenge in their design: the trade-off between the strength of the stand and its foldable size. To achieve portability, designers often tend to use thinner, lighter materials and more compact folding structures, but this often sacrifices the structural strength of the stand. When supporting heavier instruments, this design may cause the stand to deform or become unstable, affecting playing quality and instrument safety. Utility Model Content

The top of the telescopic column is provided with an upper support seat, and the bottom of the fixed column is provided with a lower support seat. The upper crossbar assembly is axially connected to the upper support seat, and the lower crossbar is axially connected to the lower support seat. The upper crossbar assembly includes an upper crossbar and a stop bar that are coaxially connected to the upper support base; In use, the lower crossbar is supported on the ground and forms a first angle with the column, the upper crossbar forms a second angle with the telescopic column, and the stop bar forms a third angle with respect to the upper crossbar. In the folded state, the upper crossbar and the stop bar are parallel, the upper crossbar assembly is folded towards the telescopic column, and the lower crossbar is folded towards the telescopic column.

[0008] A further preferred embodiment of this utility model is as follows: a reducing sleeve is provided on the fixed column, a pull pin assembly is provided on the reducing sleeve, and a stop hole is provided on the telescopic column.

[0009] A further preferred embodiment of this invention is as follows: the folding connecting unit includes a first connecting rod and a second connecting rod that are mutually pivotally connected to form an X-shape. The fixed column includes a first fixed column and a second fixed column; The first fixed post has a first sliding groove extending along its length, and the second fixed post has a second sliding groove extending along its length. The first end of the first connecting rod is axially connected to the first shrink sleeve, and the second end of the first connecting rod is provided with a first sliding pin, which can move on the second slide groove of the second fixed column. The first end of the second connecting rod is axially connected to the second reducing sleeve, and the second end of the second connecting rod is provided with a second sliding pin, which can move on the first sliding groove of the first fixed column.

[0010] A further preferred embodiment of this utility model is: the upper support includes a first root connected to the upper end of the telescopic column and an upper connecting part having a first receiving groove; The upper connecting part includes a bottom, a first side wall and a second side wall. The upper crossbar assembly can be placed in the first receiving groove. The end of the upper crossbar assembly is connected to the first side wall and the second side wall by a shaft.

[0011] A further preferred embodiment of this utility model is as follows: the upper crossbar is provided with a resilient pin that can be operated by a button, and the first sidewall is provided with a first positioning hole and a second positioning hole. The resilient pin can be selectively inserted into the first positioning hole or the second positioning hole so that the upper crossbar is at different angles.

[0012] A further preferred embodiment of this utility model is as follows: the cross section of the upper crossbar is L-shaped; when the stop bar is parallel to the upper crossbar, the stop bar can fill the step of the L-shaped upper crossbar; the end of the stop bar can rotate relative to the upper crossbar, and a rotation limiting structure is provided at the end position of the stop bar.

[0016] A further preferred embodiment of this utility model is that a silicone strip is provided on the upper end face of the vertical wall of the upper crossbar.

[0017] Compared with existing technologies, the advantages of this utility model are: This technical solution forms a transverse support frame through two parallel folding frames and the folding connecting unit between them, enabling synergistic load-bearing between the two columns, thereby significantly improving the overall stability and deformation resistance of the support. The upper and lower crossbar assemblies are rotatably connected to the columns via a shaft connection structure, forming a multi-point support system with angles A, B, and a third angle when unfolded, constituting a closed triangular support structure. This enhances the load-bearing capacity and anti-overturning performance without increasing material strength or thickness.

[0018] When folded, the upper crossbar and the stop bar fold towards the column simultaneously, and the lower crossbar can also be retracted in parallel. The overall thickness is almost equal to that of the column body. This design significantly reduces the folded volume while ensuring stability in the unfolded state, achieving a balance between lightweight and high strength, and solving the technical problem of "difficulty in balancing structural stability and portability" in existing technologies.

Detailed Implementation

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0022] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it will not be further defined and explained in subsequent figures.

[0023] like Figures 1 to 8 As shown, a foldable musical instrument stand 100 includes two folding frames 101 arranged side by side and a foldable connecting unit 102. The foldable connecting unit 102 is connected between the two folding frames 101 and is used to adjust the lateral distance between the two folding frames 101, thereby adapting to musical instruments such as electronic keyboards or speakers of different widths.

[0024] Each folding frame 101 includes a telescopic upright 10, an upper crossbar assembly 20, and a lower crossbar 30.

[0025] The telescopic column 10 consists of a fixed column 11 and a telescopic column 12. The telescopic column 12 can extend and retract along the axial direction of the fixed column 11 to adjust the overall height of the instrument stand. An upper support base 13 is fixedly connected to the top of the telescopic column 12, and a lower support base 14 is provided at the bottom of the fixed column 11. The upper crossbar assembly 20 is mounted on the upper support base 13 via a pivot, and the lower crossbar 30 is mounted on the lower support base 14 via a pivot.

[0026] The upper crossbar assembly 20 includes an upper crossbar 21 and a stop bar 22 mounted coaxially, which form a certain angle relative to each other in use to support the instrument. The lower crossbar 30 is supported on the ground, forming a first angle with the column 10, the upper crossbar 21 forms a second angle with the column 10, and the stop bar 22 forms a third angle relative to the upper crossbar 21. When the support is in the folded state, the upper crossbar 21 and the stop bar 22 are parallel to each other and fold together towards the column 10, and the lower crossbar 30 can also fold towards the column 10, which significantly reduces the size of the entire support, making it easy to carry and store.

[0027] It should be noted, and further explained, that angles A, B, and C play a crucial stabilizing role in the spatial relationship after the support frame is deployed. Angle A is an acute angle, ensuring that the lower crossbar forms an inward-convex mechanical support with the ground, giving the overall structure good resistance to tipping over; angle B is an adjustable angle, and the embodiment includes two scenarios, such as... Figure 5 As shown, in the first case, the upper horizontal bar is horizontal, and angle B is an acute angle; Figure 4 As shown, in the second case, the upper crossbar is raised by 15 degrees; at this time, angle B is approximately 90 degrees; angle C is approximately 90 degrees, so that the stop bar 22 can effectively support or limit the instrument when it is at a right angle to the upper crossbar 21, improving the reliability of placement and the safety of use. The overall angle coordination achieves the best balance between force distribution and folding portability of the bracket.

[0028] When unfolded, the upper crossbar, the upright, and the lower crossbar form a Z-shape.

[0029] like Figure 9As shown, a telescopic sleeve 15 is fitted on the fixed column 11, and a pull pin assembly 40 is installed on the telescopic sleeve 15. Multiple stop holes 121 distributed along the axial direction are provided on the outer wall of the telescopic column 12.

[0030] When the height of the bracket needs to be adjusted, the user can rotate or pull the pin assembly 40' to disengage the pin 44' from the stop hole 121. After adjusting the position of the telescopic column 12, the user can release the operating knob 41'. The pin 44' will automatically spring back under the action of the return spring 43' and insert into the new stop hole 121, thereby achieving height positioning and locking.

[0031] Specifically, the pull pin assembly 40' includes an operating knob 41', a pin fixing seat 42', a return spring 43', and a pin 44'. The pin 44' and the return spring 43' are both located in the through groove of the pin fixing seat 42'. The return spring 43' is sleeved on the pin 44', and its two ends abut against the annular stepped surfaces of the pin fixing seat 42' and the pin 44', respectively, to ensure the reliability of elastic reset.

[0032] like Figures 3 to 6 As shown, the foldable connecting unit 102 is composed of a first connecting rod 41 and a second connecting rod 42 that intersect each other and are connected by a pivot, forming an X-shaped structure.

[0033] The fixing post 11 includes a first fixing post 111 and a second fixing post 112. The first fixing post 111 is provided with a first sliding groove h1 extending along its length, and the second fixing post 112 is provided with a second sliding groove h2. The first end of the first connecting rod 41 is hinged to the first reducing sleeve 151, and the second end is provided with a first sliding pin s1, which can slide within the second sliding groove h2 of the second fixing post 112.

[0034] The first end of the second connecting rod 42 is hinged to the second retractable sleeve 152, and the second end is provided with a second sliding pin s2, which can slide in the first sliding groove h1 of the first fixed column 111.

[0035] With the above structure, the two folding frames 101 can achieve lateral distance adjustment and synchronized folding action through the cross sliding of the X-shaped connecting rods. When the user unfolds the bracket, the X-shaped structure opens and automatically maintains stability; when folding, the two connecting rods overlap and close, minimizing the overall volume of the bracket.

[0036] In addition, the upper support 13 includes a first root 131 connected to the upper end of the telescopic column 12 and an upper connecting part 132 having a first receiving groove f1.

[0037] The upper connecting part 132 includes a bottom a1, a first side wall a2 and a second side wall a3. The upper crossbar assembly 20 is placed in the first receiving groove f1, and its two ends are respectively connected to the first side wall a2 and the second side wall a3 through a rotating shaft.

[0038] The upper crossbar 21 is provided with a flexible pin 50 that can be operated by a button, and the first side wall a2 is provided with a first positioning hole a21 and a second positioning hole a22.

[0039] By pressing button 51, the spring pin 52 can be disengaged from the positioning hole, thereby adjusting the tilt angle of the upper crossbar 21; after releasing button 51, the elastic body 53 returns to its original position, and the spring pin 52 re-inserts into the selected positioning hole, thus achieving reliable locking of the upper crossbar angle, thereby adapting to the placement needs of musical instruments of different sizes and shapes.

[0040] In addition, the cross section of the upper crossbar 21 is L-shaped. When the stop bar 22 is parallel to the upper crossbar 21, the stop bar 22 can be embedded in the step v of the upper crossbar 21, so that it fits tightly in the folded state and the whole is more compact.

[0041] The upper end face of the vertical wall of the upper crossbar 21 is provided with a silicone strip m, which can effectively prevent the instrument from sliding when placed and protect the surface of the instrument from being scratched.

[0042] The end of the stop bar 22 can rotate around the end axis of the upper crossbar 21, and its end is provided with a rotation limiting structure r. The rotation limiting structure r includes a limiting block sleeved on the end of the stop bar 22. The bottom of the limiting block is provided with a rotating arc wall r1, and a transverse positioning rib r2 is formed on the arc wall r1 to limit the maximum rotation angle of the stop bar 22 and prevent excessive swinging that could cause loosening or damage.

[0043] The front end of the stop bar 22 is provided with a threaded post k, which can be connected to clamps, support plates or other auxiliary parts according to different usage scenarios, for fixing different types of musical instruments, such as electronic keyboards, speakers or tuning equipment.

[0044] The lower support 14 includes a second root portion 141 connected to the fixed column 11 and a lower connecting portion 142 having a second receiving groove f2.

[0045] The lower connecting part 142 includes a third side wall a4 and a fourth side wall a5 extending to one side. The two ends of the lower crossbar 30 are mounted on the third side wall a4 and the fourth side wall a5 by means of pivot. The lower crossbar 30 supports the ground in the unfolded state and can be folded around the pivot in the folded state so that it is basically parallel to the fixed column 11, thereby reducing the overall space occupied.

[0046] Based on the above technical solution, by setting up a folding combination structure of retractable column 10, upper crossbar assembly 20 and lower crossbar 30, and cooperating with the X-shaped linkage mechanism of folding connection unit 102, the bracket can form a stable triangular support structure when unfolded, and can be compactly folded along the column direction when folded, greatly improving the convenience of carrying and storing.

[0047] The reducing sleeve 15 on the fixed column 11, together with the pull pin assembly 40 and the multiple sets of stop holes 121 on the telescopic column 12, can achieve multiple adjustable heights; the elastic pin 50 set at the upper support seat 13, together with different positioning holes a21, a22, can adjust the tilt angle of the upper crossbar 21 according to the usage requirements, adapting to different playing postures and instrument types.

[0048] The end of the stop bar 22 is provided with a rotation limit structure r. The arc wall r1 and the convex rib r2 of the limit block effectively prevent the stop bar from rotating excessively or loosening, ensuring the stability of the support structure during use. At the same time, the automatic reset function of the elastic pin 50 improves the convenience and reliability of angle adjustment.

[0049] The upper crossbar 21 adopts an L-shaped cross-section design. When folded, the stop bar 22 can be embedded in the L-shaped step v, significantly reducing the overall thickness. The silicone strip m set on the vertical wall of the crossbar can prevent the instrument from sliding and scratching, improving the protective performance and user comfort of the bracket.
