Description

Technical Field

[0001] This invention relates to the field of musical instrument auxiliary equipment technology, specifically to a folding music stand and its folding method. Background Technology

[0002] In musical performances, practice, and rehearsals, performers typically need to use a music stand to hold sheet music for easy viewing during the performance. As an important auxiliary tool, the portability and stability of the music stand directly affect the user experience. Currently, various folding music stands are available on the market. For example, Chinese patent CN222622417U discloses a folding music stand that uses a linkage mechanism to fold the main body of the stand, thereby reducing its storage volume. However, existing folding music stands still have the following shortcomings in practical use: The folded shape is irregular and the portability is poor: Although most folding music stands can reduce the size to a certain extent, the parts are loose and the shape is irregular after folding. They often still need to be carried in a separate bag and cannot be put directly into the side pocket of a backpack or held in hand. For musicians who need to perform impromptu outdoors, on the street and other occasions, it is still inconvenient to carry. The folding mechanism is complex and the unfolding operation is not intuitive: The existing folding structure of the music stand usually involves multiple hinge points and locking parts. Users need to manually adjust it multiple times to complete the unfolding or folding. The operation steps are cumbersome, lack intuitiveness, and affect the efficiency of use. The tripod becomes bulky when folded: Traditional music stand tripods tend to have their legs spread out when folded, making it impossible to fold them into a compact shape. This results in an overall bulky size when stored, making them inconvenient to carry. Even when folded, the existing music stand is still quite large: Even after folding, the existing music stand is still quite long or thick, making it difficult to achieve an extremely compact design and failing to meet musicians' need for "grab and go" portability. Therefore, it is necessary to design a new type of folding music stand and its folding method to solve the above problems. Summary of the Invention

[0003] Purpose of the invention The purpose of this invention is to provide a folding music stand and its folding method to solve the problems of irregular shape, large size, poor portability, and non-compact tripod folding of existing folding music stands.

[0004] Technical solution To achieve the above objectives, the present invention provides the following technical solution: A folding music stand includes a main frame (100), a tripod (200), a telescopic rod (300), a locking mechanism (400), a top cover (500), and an upper and lower hinge mechanism (600). The main frame (100) has an unfolded state and a folded state, and includes: an upper left rod (101), an upper right rod (102), a middle left rod (103), a middle right rod (104), a short left crossbar (105), a short right crossbar (106), a long left crossbar (107), a long right crossbar (108), a base plate (111), and a left spectrum stand (109), a right spectrum stand (110), a left pressure bar (112), and a right pressure bar (113) serving as spectrum stands; the upper left rod (101), the middle left rod (103), the short left crossbar (105), the long left crossbar (107), the left spectrum stand (109), and the base plate (111) are hinged together to form a left folded state. The right folding linkage group consists of the upper right rod (102), the middle right rod (104), the short right crossbar (106), the long right crossbar (108), the right music stand (110), and the base plate (111), which are hinged together to form the right folding linkage group. The left music stand (109) and the right music stand (110) are located at the lower part of the left and right folding linkage groups, respectively, and are themselves part of the linkage group, used to support the musical score. The base plate (111) is located at the center of the main frame (100) and connects the left and right folding linkage groups. The left pressure rod (112) and the right pressure rod (113) are installed on the left music stand (109) and the right music stand (110), respectively, to press down the musical score. The tripod (200) is installed at the lower part of the main frame (100) to support the entire music stand; it includes: tripod slider (201), tripod bottom connector (202), tripod short rod one (203), tripod narrow long rod one (204), tripod short rod two (205), tripod narrow long rod two (206), tripod short rod three (207), and tripod wide long rod (208). The telescopic rod (300) is a damped telescopic rod (301), which is set between the main frame (100) and the tripod (200) and is used to adjust the height of the music stand; The locking mechanism (400) is disposed on the main frame (100) and is used to lock the main frame (100) in the folded state; it includes: a self-locking press buckle claw box (401) and a self-locking press buckle head (402). The top cover (500) is connected to the top of the base plate (111) at its root, and includes: a top cover body (501), a magnetic buckle (upper) (502), and a magnetic buckle (lower) (503). The upper and lower hinge mechanism (600) is disposed between the main frame (100) and the telescopic rod (300) to realize the rotation and limit of the main frame (100) relative to the telescopic rod (300); it includes: an upper connecting block (601), a lower connecting block (602) and a damping hinge (603). The length ratio and axis position of each link of the main frame (100) are set such that when the frame changes from the unfolded state to the folded state, all the links can be sequentially folded into a straight line and then integrated into a regular cuboid. A folding method for a folding music stand includes the following steps: Step 1: Open the top cover (500), and rotate the tripod (200) and telescopic rod (300) outward from the bottom of the main frame (100) so that they are roughly parallel to the longitudinal axis of the main frame (100); Step 2: Press the self-locking snap button (402), the self-locking snap button claw box (401) is released, and the upper left rod (101) and the upper right rod (102) automatically spring open to both sides under the action of the spring; Step 3: Pull the upper left rod (101) and upper right rod (102) upward to the vertical position to initially unfold the left and right folding linkage groups; Step 4: Pull down the left staff (109) and right staff (110) respectively to unfold each horizontal bar in sequence and form a complete musical score support surface; Step 5: Push the tripod slider (201) downwards so that it slides along the telescopic rod (300). The eccentric structure forces each leg of the tripod to open outwards synchronously and in the same direction along the tangential direction to the predetermined angle.

[0005] Beneficial effects Compared with the prior art, the present invention has the following advantages and beneficial effects: By optimizing the length ratio and axis position of each link of the main frame (100), the main frame can be completely folded into a straight line, thus forming a regular cuboid. The volume after folding is significantly smaller than that of a traditional music stand, and it can be directly put into the side pocket of a backpack without additional packaging. By setting a press-type self-locking buckle (400), the folded state can be released with one click, and the unfolding is intuitive and quick when combined with manual operation. Through the eccentric limiting structure in the tripod (200) and the limiting protrusion on the telescopic rod (300), the legs of the tripod (200) can only be extended synchronously in the same direction along the tangential direction, without the need to manually adjust the angle of each leg, while ensuring that the shape is flat and the space utilization is high after folding. The overall structure is compact, and the material can be bamboo, which is lightweight and has a natural texture; the top cover (500) closes magnetically, which is beautiful and easy to open and close. The provided folding method has clear steps and a smooth operation, enabling users to quickly unfold and store the music stand, significantly improving the user experience.

[0008] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the invention. Example like Figures 1 to 15 As shown, this embodiment provides a folding music stand and its folding method. (I) Overall Structure like Figure 1 As shown, the overall structure of the present invention includes a main frame (100), a tripod (200), a telescopic rod (300), a locking mechanism (400), a top cover (500), and an upper and lower hinge mechanism (600). The relative positions of the components are shown in the figure. (ii) Folded structure like Figure 2As shown, the music stand is in a fully folded state. At this time, the connecting rods of the main frame (100) are folded into a straight line, forming a regular cuboid. The overall dimensions after folding are approximately: depth 55mm, width 40mm, and height 288mm. This size is about half that of a traditional folding music stand, and it can be directly placed in a backpack side pocket or carried by hand. The top cover (500) of the main frame (100) is attached to the magnetic snap (lower) (503) on the wide and long pole (208) of the tripod via a magnetic snap (upper) (502), thus fixing the whole structure. The support rods of the tripod (200) are folded around the telescopic rod (300), making the whole structure compact. (iii) Exemplary dimensions of major components To meet the requirement of full disclosure, the specific dimensions (unit: mm) of each major component in this embodiment are given below. In actual manufacturing, these dimensions can be adjusted within a reasonable range as needed. Main frame (100): Top left rod (101): Length 212, Width 15, Thickness 2 Upper right rod (102): Length 212, Width 15, Thickness 2 Left center bar (103): Length 205, Width 15, Thickness 2 Right center bar (104): Length 205, Width 15, Thickness 2 Short left crossbar (105): Length 110, Width 15, Thickness 2 Short right crossbar (106): Length 110, Width 15, Thickness 2 Long left horizontal bar (107): Length 125, Width 15, Thickness 2 Long right crossbar (108): Length 125, Width 15, Thickness 2 Left spectral platform (109): Length 250, Width 15, Thickness 2 Right spectral stand (110): Length 250, Width 15, Thickness 2 Base plate (111): Length 277, Width 40, Thickness 4 Left pressure bar (112): 200 mm long Right pressure bar (113): 200 mm long Tripod (200): Tripod slider (201): Side length 30, height 1.5 Tripod bottom connector (202): Side length 30, height 1.5 Tripod short pole 1 (203): Length 130, Width 15, Thickness 2 Tripod narrow pole 1 (204): Length 230, Width 30, Thickness 2 Tripod short pole 2 (205): Length 130, Width 15, Thickness 2 Tripod narrow pole 2 (206): Length 230, Width 30, Thickness 2 Tripod short pole 3 (207): Length 130, Width 15, Thickness 2 Tripod wide and long pole (208): Length 230, Width 40, Thickness 2 Telescopic pole (300): Damped telescopic rod (301): Telescopic range 270 to 2000 Locking mechanism (400): The dimensions of the self-locking press-fit clip box (401) and the self-locking press-fit head (402) are adapted to the overall structure and will not be described in detail here. Top cover (500): The dimensions of the top cover body (501) match the top of the main frame in the folded state; the magnetic buckle (upper) (502) and the magnetic buckle (lower) (503) are standard parts, and their dimensions are not limited. Upper and lower hinge mechanism (600): Upper connecting block (601): Length 46, Width 40, Height 28 Lower connecting block (602): Length 31, Width 40, Height 25 Damping hinge (603): Adapted to the overall structure, size is not limited. (iv) Folding and unfolding process (product usage instructions) The folding and unfolding method of this embodiment is described in detail below with reference to the accompanying drawings: Step 1: Open the top cover and rotate the tripod like Figure 3 As shown, the user lifts the top cover body (501) upwards, causing the magnetic clasp to detach. The top cover body (501) is preferably made of PU leather, which is comfortable to the touch and easy to open and close. Subsequently, the tripod (200) and telescopic rod (300) are rotated outwards from the bottom of the main frame (100) so that they are approximately parallel to the longitudinal axis of the main frame (100). At this time, the damping hinge (603) in the upper and lower hinge mechanism (600) provides smooth rotational resistance. Step 2: Press the self-locking buckle to release the upper left and upper right levers. like Figure 4 As shown, when the user presses the self-locking snap button (402), the self-locking snap button jaw box (401) is released. The upper left rod (101) and the upper right rod (102) automatically spring open a short distance to the sides under the action of the internal spring. Figure 5 for Figure 4 The enlarged view at point A clearly shows the process of the pawl disengaging from the locking position when the self-locking push-button head (402) is pressed down. Step 3: Pull up the upper left and upper right bars until they are vertical. like Figure 6As shown, the user pulls the upper left rod (101) and the upper right rod (102) upwards by hand, causing them to rotate upwards about the hinge axis. Figure 7 As shown, when the upper left rod (101) and the upper right rod (102) are pulled up to the vertical position (about 180°), the left folding linkage group and the right folding linkage group complete the initial unfolding. Step 4: Pull down the left and right music stands to unfold the main frame. like Figure 8 As shown, the user pulls down the left music stand (109) and the right music stand (110) respectively. The left music stand (109) causes the crossbars of the left folding linkage group (short left crossbar 105, long left crossbar 107, etc.) to unfold, and the right music stand (110) causes the crossbars of the right folding linkage group (short right crossbar 106, long right crossbar 108, etc.) to unfold. Finally, the left music stand (109) and the right music stand (110) are located at the lower part of the main frame (100) (i.e., the front side in the use state), forming a complete music score support surface. The width of this support surface after unfolding is about 505mm and the height is about 240mm, which is comparable to the size of a standard music stand, and can firmly hold paper music scores or tablet computers. The base plate (111) is located in the center and connects the left and right sides. Step 5: Unfold the tripod like Figure 9 As shown, the user pushes the tripod slider (201) downwards, causing it to slide down along the telescopic rod (300). The tripod slider (201) causes the tripod short rod one (203), tripod short rod two (205), and tripod short rod three (207) to push the tripod narrow long rod one (204), tripod narrow long rod two (206), and tripod wide long rod (208) outwards, respectively. Figure 10 This shows the tripod when fully extended, with the legs arranged radially. Figures 11 to 14 for Figures 9 to 10 The series of enlarged images at point B during the process demonstrate in detail the working principle of the eccentric mechanism when the tripod is deployed. For example... Figure 11 As shown, in the initial state, the connection between the narrow and long tripod rods (204, 206, 208) and the tripod bottom connector (202) is eccentric compared to the short tripod rods (203, 205, 207). As the tripod slider (201) moves downward, the eccentric wheel gradually interacts with the legs. Figure 12 ), and continue to rotate ( Figure 13 This forces each leg to open outward synchronously and in the same direction only along the tangential direction. Figure 14 The eccentric wheel is fully engaged with the outriggers, and the outriggers are extended to a predetermined angle (preferably, the angle between each outrigger and the vertical direction is 60°-70°). The limiting protrusion on the telescopic rod (300) also limits the maximum extension angle of the tripod, ensuring stability. Step Six: Fully Deployed like Figure 15 As shown, the music stand is in its fully extended state. At this time, all the connecting rods of the main frame (100) are fully extended, and the left music stand (109) and the right music stand (110) form a wide support surface for the music score. The left and right music holding rods (112 and 113) are used to hold the music score down. The tripod (200) is fully extended and stably supported on the ground. The user can adjust the height of the music stand through the damping telescopic rod (301), which can be continuously adjusted within the range of 420mm to 2620mm (approximately 420-800mm when used in a seated position and approximately 800-2620mm when used in a standing position) to accommodate performers of different heights and performance scenarios such as seated and standing positions. The damping telescopic rod (301) is preferably a multi-stage telescopic structure with built-in damping oil, which allows for smooth adjustment and can be stopped at any position. (v) Folding and storage operation When folding, reverse the steps described above: first retract the telescopic rod (300), then fold the tripod (200) upwards, then fold the left and right music stands (109) upwards, and then press down on the upper left (101) and upper right (102) rods to bring them together; the self-locking buckles will automatically lock. Next, rotate the tripod (200) and telescopic rod (300) inwards to bring them together with the main frame (100), and finally cover with the top cover (500), so that the magnetic snap (upper) (502) on the top cover attaches to the magnetic snap (lower) (503) on the wide and long rod (208) of the tripod, completing the overall fixation. After folding, the music stand returns to its original position. Figure 2 The regular rectangular shape shown has an overall size of approximately 55mm × 40mm × 288mm and can be placed directly into the side pocket of a backpack. (vi) Selection of materials and processes The main frame (100) is preferably made of bamboo, with a finely polished and environmentally friendly coating, giving it a lightweight, natural, and warm texture. The cross-sectional dimensions of each member can use the example values ​​mentioned above, but can be adjusted within a reasonable range according to strength requirements during actual manufacturing (e.g., width 10-15mm, thickness 1.5-3mm). The top cover body (501) is preferably made of PU leather. Other metal connectors (such as hinge shafts, self-locking springs, etc.) are made of stainless steel or rust-proof steel to ensure durability. The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
