Abstract
Description
Technical Field
[0001] This invention relates to a clamp and a method for installing the clamp, and more particularly to a clamp that can be stably installed on various objects and a method for installing the clamp. Background Technology
[0002] For example, Patent Document 1 describes a microphone mounting device 200 (clamp), which includes: a frame 230 (frame) for holding a microphone or similar object; and a lower claw 201 and an upper claw 203 that protrude forward from the frame 230 and are spaced apart vertically. The spacing between the lower claw 201 and the upper claw 203 is configured to be adjustable by operating a handle (knob) 205.
[0003] The lower jaw 201 and upper jaw 203 have arc-shaped recesses 211 to 214 arranged one after the other. Compared with recesses 211 and 213, recesses 212 and 214 have larger radii of curvature, so rods of different diameters can be clamped by the lower jaw 201 and upper jaw 203. That is, the mounting device 200 can be mounted on rods (objects) of different types.

[0007] [The problem the invention aims to solve]
[0008] This technology requires a fixture that can be stably mounted on various objects.
[0009] This invention was made to meet the aforementioned requirements, and its purpose is to provide a clamp that can be stably installed on various objects and a method for installing the clamp.
[0010] [Technical means to solve the problem]
[0011] To achieve the aforementioned objective, the clamp of the present invention includes: a frame capable of holding an object; and upper and lower jaws protruding forward from the frame and capable of clamping an object by adjusting their vertical spacing. An upwardly recessed upper clamping surface is formed on the lower surface of the upper jaw, and a downwardly recessed lower clamping surface is formed on the upper surface of the lower jaw. The entire upper clamping surface formed between the rear end of the upper clamping surface located at the rearmost part of the upper jaw and the front end of the upper clamping surface located at the foremost part of the upper jaw is positioned higher than both the rear end and the front end of the upper clamping surface. The lower clamping surface formed between the rear end of the lower clamping surface at the rearmost part of the lower jaw and the front end of the lower clamping surface at the foremost part of the lower jaw is located further below the rear end and front end of the lower clamping surface. In a side view of the upper jaw and the lower jaw, if the imaginary line connecting the front end of the upper clamping surface and the upper end of the rear end side of the upper clamping surface is taken as the first imaginary line, and the imaginary line connecting the front end of the lower clamping surface and the lower end of the rear end side of the lower clamping surface is taken as the second imaginary line, the interval between the first imaginary line and the second imaginary line gradually narrows towards the front side.
[0012] The clamp of the present invention includes: a frame capable of holding an object; and an upper jaw and a lower jaw protruding forward from the frame and capable of clamping an object by adjusting their vertical spacing. An upper clamping surface recessed upward is formed on the lower surface of the upper jaw, and a lower clamping surface recessed downward is formed on the upper surface of the lower jaw. The clamp includes a first upper jaw and a second upper jaw disposed at a distance from the side of the first upper jaw. When the distance between the upper jaw and the lower jaw narrows, the lower clamping surface passes through the gap between the first upper jaw and the second upper jaw, thereby allowing the upper clamping surface to intersect the lower clamping surface.
[0013] The clamp of the present invention includes: a frame capable of holding an object; and an upper jaw and a lower jaw protruding from the frame to the front side and capable of clamping an object by adjusting their vertical spacing. An upper clamping surface recessed upwards and a pair of upper planes connected to the front and rear ends of the upper clamping surface are formed on the lower surface of the upper jaw. A lower clamping surface recessed downwards and a pair of lower planes connected to the front and rear ends of the lower clamping surface are formed on the upper surface of the lower jaw. A pair of front surfaces of the frame, extending vertically and horizontally, are formed at intervals to the left and right of the upper and lower planes, enabling the object to be clamped using the upper plane, the lower plane, and the front surface.
[0014] The clamping method of the present invention is a method of installing the clamp as follows: the clamp includes: a frame capable of holding an object; and upper and lower jaws protruding forward from the frame and capable of clamping an object by adjusting their vertical spacing. An upper clamping surface with an upwardly recessed shape is formed on the lower surface of the upper jaw, and a lower clamping surface with a downwardly recessed shape is formed on the upper surface of the lower jaw. The upper clamping surface formed between the rear end of the upper clamping surface located at the rearmost part of the upper jaw and the front end of the upper clamping surface located at the foremost part of the upper jaw is positioned higher than both the rear end and the front end of the upper clamping surface. The lower clamping surface formed between the rear end of the lower clamping surface located at the rearmost part of the lower jaw and the front end of the upper clamping surface located at the foremost part of the lower jaw... The lower clamping surface, formed between the front ends of the lower clamping surface, is located further below the rear and front ends of the lower clamping surface. In the clamping method, the object is clamped using the upper clamping surface and the lower clamping surface, thereby installing the clamp on the object. The upper clamping surface and the lower clamping surface are formed such that, in a side view of the upper jaw and the lower jaw, the imaginary line connecting the front end of the upper clamping surface and the upper end of the rear end side of the upper clamping surface is taken as the first imaginary line, and the imaginary line connecting the front end of the lower clamping surface and the lower end of the rear end side of the lower clamping surface is taken as the second imaginary line, and the interval between the first imaginary line and the second imaginary line gradually narrows towards the front side.
[0015] The clamp installation method of the present invention is a method of installing a clamp comprising: a frame capable of holding an object; and upper and lower jaws protruding forward from the frame and capable of clamping an object by adjusting their vertical spacing. An upper clamping surface recessed upwards is formed on the lower surface of the upper jaw, and a lower clamping surface recessed downwards is formed on the upper surface of the lower jaw. The clamp includes a first upper jaw and a second upper jaw arranged at a distance from the side of the first upper jaw. In the clamp installation method, when the distance between the upper and lower jaws narrows, the lower clamping surface passes through the gap between the first and second upper jaws, thereby using the intersecting upper and lower clamping surfaces to clamp the object, thus installing the clamp on the object.
[0016] The clamping method of the present invention is a method of installing the following clamp, the clamp comprising: a frame capable of holding an object; and upper and lower jaws protruding from the frame to the front side and capable of clamping an object by adjusting their vertical spacing. An upper clamping surface recessed upwards and a pair of upper planes connected to the front and rear ends of the upper clamping surface are formed on the lower surface of the upper jaw. A lower clamping surface recessed downwards and a pair of lower planes connected to the front and rear ends of the lower clamping surface are formed on the upper surface of the lower jaw. A pair of front surfaces of the frame extending vertically and vertically are formed with left and right spacing behind the upper and lower planes. In the clamping method, the object is clamped by the upper plane, the lower plane, and the front surface, thereby installing the clamp on the object. Attached Figure Description

[0090] Hereinafter, preferred embodiments will be described with reference to the accompanying drawings. First, referring to... Figure 1 and Figure 2 of (a) Figure 2 (b) describes the overall structure of fixture 1. Figure 1 This is a perspective view of the front surface of the fixture 1, which holds the device 100 in its current state. Figure 2 (a) is a perspective view of the rear surface of the fixture 1, showing the state after the equipment 100 has been removed. Figure 2 (b) is a perspective view of the front surface of the device 100 in the state of being unloaded from the fixture 1.
[0091] also, Figure 1 and Figure 2 of (a) Figure 2 In (b), the arrows UD, FB, and LR represent the up-down, front-back, and left-right directions relative to clamp 1, respectively (and so in subsequent figures). However, the directions of clamp 1 may not necessarily correspond to the directions of the object on which clamp 1 is mounted.
[0092] like Figure 1 and Figure 2 of (a) Figure 2As shown in (b), the clamp 1 is a device for mounting a wireless adapter or similar device 100 onto an object. Examples of objects on which the clamp 1 is mounted include rods 200 and 300 for supporting electronic musical instruments (see reference). Figure 5 of (a) Figure 5 (b) The device 100 is used (connected to the electronic instrument) when playing an electronic musical instrument supported by the rods 200 and 300. The device 100 is held on the rear surface (face facing the arrow B side) of the frame 2 of the clamp 1.
[0093] The frame 2 includes a rear wall 20 forming its rear surface, and a pair of side walls 21 protruding forward (towards arrow F) from the left and right (arrow LR) ends of the rear wall 20. The lower ends (arrow D ends) of the rear wall 20 and the pair of side walls 21 are connected to each other by a lower wall 22 (see reference). Figure 1 The rear wall 20 and the upper ends (the ends on the U side of the arrow) of a pair of side walls 21 are connected to each other through the upper wall 23. These walls 20-23 constituting the frame 2 are integrally formed using resin material.
[0094] Upper claws 24 and 25 protrude forward from the upper ends of a pair of sidewalls 21, and are arranged in a pair with left and right sides spaced apart. The pair of upper claws 24 and 25 are integrally formed with the sidewalls 21 or the upper wall 23 of the frame 2, but the upper claws 24 and 25 can also be formed separately from the frame 2.
[0095] The lower surfaces of a pair of upper jaws 24 and 25 are configured as upper clamping surfaces 240 and 250 for clamping objects (see upper clamping surface 250 for reference). Figure 1 Below a pair of upper jaws 24 and 25, a lower jaw 3 protrudes forward from the frame 2. An elastic body 4 is fixed to the upper surface of the lower jaw 3. The upper surface of the elastic body 4 is configured as a lower clamping surface 40 for clamping the object together with the upper clamping surface 240 of the upper jaw 24 and the upper clamping surface 250 of the upper jaw 25.
[0096] The lower claw 3 is formed using the same resin material as the frame 2 (upper claw 24, upper claw 25), and the elastomer 4 is formed using rubber or a high-elasticity elastomer. The elastomer 4 can be integrally formed with the lower claw 3 by means of two-color molding or insert molding, or it can be joined with the lower claw 3 by means of bonding.
[0097] A front-open space S is formed on frame 2 (see reference). Figure 1The rear end of the lower jaw 3 (located further rearward than the lower clamping surface 40) is inserted into the space S. The space S is a cavity surrounded by walls 20-23, and a pivot 5 (shaft member) for moving the lower jaw 3 up and down is provided within the space S. The pivot 5 is a long screw (a full screw without a head) with external threads formed on its outer circumferential surface. The pivot 5 is formed as an axis along the vertical direction, and the lower wall 22 and upper wall 23 of the frame 2 are vertically connected by the pivot 5.
[0098] Details will be described later. A through hole 230 for the passage of the rotating shaft 5 is formed on the upper wall 23 of the frame 2 (see reference). Figure 3 (a) A knob 6 (operating element) is fixed to the upper end of the rotating shaft 5 protruding upward from the through hole 230. By rotating the rotating shaft 5 using the knob 6, the lower claw 3 moves up and down, thereby adjusting the interval between the upper claw 24, the upper claw 25 and the lower claw 3.
[0099] Then, referring to Figure 2 of (a) Figure 2 (b) and Figure 3 of (a) Figure 3 (b) describes the retaining structure of the device 100 based on the frame 2. Figure 3 (a) is Figure 1 A cross-sectional view of clamp 1 at line IIIa-IIIa. Figure 3 (b) is Figure 3 A cross-sectional view of clamp 1 at line IIIb-IIIb in (a). Furthermore, Figure 3 (a) is a cross section orthogonal to the left-right direction (arrow LR direction) and is a cross section view of the shaft containing the rotation axis 5.
[0100] like Figure 2 of (a) Figure 2 (b) and Figure 3 of (a) Figure 3 As shown in (b), a retaining portion 26 for holding the device 100 is integrally formed on the rear wall 20 of the frame 2. The retaining portion 26 protrudes to the rear side (arrow B side) of the rear wall 20, and four retaining pieces 260a to 260d extend from the rear end of the retaining portion 26 in the up, down, left, and right directions (arrow UD direction and arrow LR direction) of the retaining portion 26.
[0101] The pair of retaining plates 260a and 260b extending vertically from the retaining plates 260a to 260d are respectively formed into flanges extending horizontally (see reference). Figure 3 (a) A groove 261a and groove 261b extending laterally are formed between the retaining pieces 260a and 260b and the rear surface of the rear wall 20 (frame 2) (see reference). Figure 3 (a)).
[0102] The shapes of retaining plates 260a to 260d are rotationally symmetrical (fourfold symmetry) about the front-back axis. Therefore, although the illustration is omitted, the left and right retaining plates 260c and 260d (refer to...) Figure 2 A groove extending vertically is also formed between (a) and the rear wall 20, forming a structure in which the device 100 can be installed from the four sides of the holding part 26.
[0103] The device 100 is held in place by retaining pieces 260a-260d or slots 261a and 261b. An insertion hole 102 is formed on the front surface 101 (the surface to be held) of the device 100 for inserting the retaining pieces 260a-260d of the retaining part 26. The insertion hole 102 is a generally rectangular recess, and a pair of sliding pieces 103a and 103b facing each other are formed on the leading edges (the ends on the side of arrow F) of the upper and lower walls of the insertion hole 102. The sliding pieces 103a and 103b are inserted into the slots 261a and 261b of the retaining part 26 (see reference). Figure 3 The part of (a)).
[0104] A pair of sliding plates 103a and 103b are respectively formed as flanges extending to the left and right (see reference). Figure 3 (a) A left-right extending groove 104a and groove 104b are formed between the bottom surface of the insertion hole 102 (the surface facing the retaining part 26) and the sliding pieces 103a and 103b (groove 104a refers to...). Figure 3 (a)). The upper and lower pair of slots 104a and 104b respectively have openings 140a and 140b on the left side (arrow L side) of the device 100 (refer to...). Figure 2 (b)
[0105] When the retaining part 26 holds the device 100, retaining pieces 260a to 260d are inserted into the openings 140a and 140b of the grooves 104a and 104b (so that the sliding pieces 103a and 103b slide along the grooves 261a and 261b). The insertion of retaining pieces 260a to 260d into the grooves 104a and 104b is aided by the inclined portions 130a and 130b of the pair of sliding pieces 103a and 103b (see reference). Figure 2 (b)) guidance.
[0106] The inclined portions 130a and 130b are inclined such that their relative narrowing gradually decreases as they move away from the openings 140a and 140b. As a result, the retaining pieces 260a to 260d can be smoothly inserted into the slots 104a and 104b by sliding the slots 261a and 261b of the retaining portion 26 along the inclined portions 130a and 130b.
[0107] The upper and lower sliding pieces 103a and 103b are spaced apart from each other by a distance corresponding to the depth of the upper and lower grooves 261a and 261b of the retaining part 26. When the retaining pieces 260a to 260d are inserted into the ends of the grooves 104a and 104b, the upper and lower sliding pieces 103a and 103b hook onto the grooves 261a and 261b of the retaining part 26 (see reference). Figure 3 (a)). The device 100 is provided with hooks 105 for fixing the grooves 261a and 261b to the sliding pieces 103a and 103b.
[0108] The hook 105 rises from the wall of the insertion hole 102 at the end of the slots 104a and 104b (opposite to the openings 140a and 140b), and a claw 150 is formed at the front end of the hook 105 (see reference). Figure 2 (b) When the retaining pieces 260a to 260d slide along the grooves 104a and 104b, the claw portion 150 of the hook 105 contacts the rear surface of the retaining portion 26, thereby causing the hook 105 to elastically deform rearward. The elastic deformation of the hook 105 is permitted by the recess 106 formed on the rear side (insertion hole 102) of the hook 105. The recess 106 is a recess that extends laterally from the base end to the front end of the hook 105.
[0109] When the claw portion 150 of hook 105 passes past retaining plates 260a to 260d, hook 105, after elastic deformation to the rear, returns to its original shape, thereby hooking the claw portion 150 onto the front end of retaining plates 260a to 260d. Trapezoidal recesses 262a to 262d are formed on the front end faces of each of retaining plates 260a to 260d (see reference). Figure 2 (a) Although the illustration is omitted, the claw portion 150 of hook 105 hooks onto these recesses 262a to 262d (e.g., in...). Figure 1 In the installed state of the device 100 shown, the claw 150 hooks onto the recess 262c (see reference). Figure 2 (a)). By hooking the recesses 262a to 262d onto the claw 150, the device 100 is prevented from detaching from the holding portion 26.
[0110] The clamp 1 is mounted on the object in such a manner that the device 100 is held in the holding part 26 (or, after the clamp 1 is mounted on the object, the device 100 is held in the holding part 26). See reference. Figure 3 of (a) Figure 3 (b) describes the structure used to move the lower jaw 3 up and down when installing the clamp 1.
[0111] like Figure 3 of (a) Figure 3As shown in (b), a through hole 230 is formed in the upper wall 23 of the frame 2, and the rotating shaft 5 is inserted into the through hole 230 from the upper side. A small diameter portion 50 with a locally reduced diameter is formed at the lower end of the rotating shaft 5, and the small diameter portion 50 is inserted into the through hole 220 formed in the lower wall 22 of the frame 2.
[0112] The lower claw 3 has a through hole 30 through which the rotating shaft 5 passes, and a nut 31 is fixed on the inner circumferential side of the through hole 30. In addition, in this embodiment, the lower claw 3 and the nut 31 are integrally formed by embedding, but the nut 31 can also be joined on the inner circumferential side of the through hole 30 by connecting or the like.
[0113] With the rotating shaft 5 fastened to the internal thread on the inner circumference side of the nut 31, the small diameter portion 50 of the rotating shaft 5 is inserted into the through hole 220 of the lower wall 22, and an E-ring 7 is installed on the upper end side of the rotating shaft 5, thereby assembling the lower claw 3 and the rotating shaft 5 into the frame 2. In the assembled state of the lower claw 3, the vertical movement of the rotating shaft 5 is restricted by the contact between the stepped portion on the upper end side of the small diameter portion 50 and the lower wall 22, or by the contact between the E-ring 7 and the upper wall 23.
[0114] Furthermore, in the assembled state of the lower claw 3, the gaps (or contact) between the rear wall 20 and the left and right side walls 21 of the frame 2 and the rear surface 32 and the left and right side surfaces 33 of the lower claw 3 are extremely small. Therefore, when the rotating shaft 5 is rotated using the knob 6, the rotation of the lower claw 3 is restricted by the contact between the rear wall 20 or the side walls 21 and the lower claw 3 (only the rotating shaft 5 rotates alone). As a result, the lower claw 3 moves up and down along the rotating shaft 5. In other words, the up and down movement of the lower claw 3 is guided by the rear wall 20 or the side walls 21 of the frame 2.
[0115] By adjusting the distance between the upper jaws 24 and 25 and the lower jaw 3 through the up-and-down movement of the lower jaw 3, various objects can be clamped using the upper clamping surface 240 of the upper jaw 24, the upper clamping surface 250 of the upper jaw 25, and the lower clamping surface 40 of the lower jaw 3 (elastic body 4). (Refer to...) Figure 4 The detailed structure of the upper and lower clamping surfaces 240, 250, and 40 is described below.
[0116] Figure 4 It is Figure 3 (a) is a partially enlarged cross-sectional view of the clamp 1, enlarged from part IV. Furthermore, in the following description, the detailed structure of the upper clamping surface 250 of the upper jaw 25, located on the right side of the clamp 1, will be explained. The upper clamping surface 240 of the upper jaw 24 (refer to...) Figure 1 or Figure 2 of (a) Figure 2 (b) is the same structure as the upper clamp surface 250.
[0117] like Figure 4As shown, the upper clamping surface 250 includes a rear clamping surface 250a constituting its rear end (the end on the side of arrow B), a large-diameter clamping surface 250b connected to the front end of the rear clamping surface 250a (the end on the side of arrow F), a small-diameter clamping surface 250c connected to the front end of the large-diameter clamping surface 250b, and a front clamping surface 250d connected to the front end of the small-diameter clamping surface 250c.
[0118] The lower surface 251 of the rear end side of the upper jaw 25 is connected to the rear end 250e (the rear end side of the rear clamping surface 250a) of the upper clamping surface 250, and the lower surface 252 of the front end side of the upper jaw 25 is connected to the front end 250f (the front end side of the front clamping surface 250d). Hereinafter, the dimensions from the rear end 250e to the front end 250f of the upper clamping surface 250 will be described as the front-rear dimensions of the upper clamping surface 250.
[0119] The rear clamping surface 250a is an arc with a radius of curvature smaller than the longitudinal dimension of the upper clamping surface 250, and is formed as an arc convex towards the rearward and upward side. The large-diameter clamping surface 250b is an arc with a radius of curvature larger than the rear clamping surface 250a (the longitudinal dimension of the upper clamping surface 250), and is formed as an arc convex towards the forward and upward side. The small-diameter clamping surface 250c is an arc with a radius of curvature smaller than the large-diameter clamping surface 250b (the longitudinal dimension of the upper clamping surface 250), and is formed as an arc convex towards the forward and upward side.
[0120] The front clamping surface 250d is formed as an arc with the same radius of curvature as the large-diameter clamping surface 250b. When an imaginary line V1 (along the arc of the large-diameter clamping surface 250b) extending forward from the large-diameter clamping surface 250b is drawn, the front clamping surface 250d is formed at a position coinciding with the imaginary line V1. In other words, when the large-diameter clamping surface 250b and the front clamping surface 250d are considered together as a single clamping surface V1, the small-diameter clamping surface 250c is formed in the region encompassing the center of the single clamping surface V1 in the front-rear direction.
[0121] The lower clamping surface 40 on the lower jaw 3 side includes a rear clamping surface 40a constituting its rear end portion and a large-diameter clamping surface 40b connected to the front end of the rear clamping surface 40a. The upper surface 41 on the rear end side of the elastomer 4 is connected to the rear end 40c (rear end side of the rear clamping surface 40a) of the lower clamping surface 40, and the upper surface 42 on the front end side of the elastomer 4 is connected to the front end 40d (front end side of the large-diameter clamping surface 40b) of the lower clamping surface 40. Hereinafter, the dimensions from the rear end 40c to the front end 40d of the lower clamping surface 40 will be described as the front-rear dimensions of the lower clamping surface 40.
[0122] The rear clamping surface 40a is an arc with a radius of curvature smaller than the longitudinal dimension of the lower clamping surface 40, and is formed in an arc shape that bulges downwards and backwards. The large-diameter clamping surface 40b is an arc with a radius of curvature larger than that of the rear clamping surface 40a (the longitudinal dimension of the lower clamping surface 40), and is formed in an arc shape that bulges downwards and forwards. Multiple protrusions 40e are formed on the upper surface of the arc-shaped large-diameter clamping surface 40b to prevent the lower clamping surface 40 (large-diameter clamping surface 40b) from bulging relative to the rods 200 to 400 (see reference). Figure 5 of (a) Figure 5 (b) and Figure 6 of (a) Figure 6 (b) and other objects glide.
[0123] Then, referring to Figures 4-6 (b) describes the structure for clamping rods 200 to 400 of different diameters via the upper and lower clamping surfaces 250 and 40. Figure 5 (a) is a cross-sectional view of the clamp 1 showing the state of holding the rod 200 with a larger diameter. Figure 5 (b) is a cross-sectional view of the clamp 1 showing the state of clamping the rod 300 with a smaller diameter.
[0124] Figure 6 (a) is a cross-sectional view of the clamp 1 showing the state of holding a rod 400 with a smaller diameter. Figure 6 (b) is a cross-sectional view of the clamp 1 showing the state in which the rod 400 is held using the small-diameter clamping surface 250c. Furthermore, Figure 5 of (a) Figure 5 (b) and Figure 6 of (a) Figure 6 (b) is with Figure 3 (a) is a cross-sectional view showing the state in which device 100 has been removed from fixture 1 (described later). Figure 7 of (a) Figure 7 The same applies to (b).
[0125] In addition, Figure 5 of (a) Figure 5 (b) and Figure 6 of (a) Figure 6 In (b), the outline of rods 200 to 400, on which clamp 1 is mounted, is illustrated with a double-dotted line. These rods 200 to 400 are cylindrical parts that form part of the support (drum set) for electronic percussion instruments such as electronic drums or electronic cymbals.
[0126] First, the prior art for this type of clamping rod (US Patent Application Publication No. 2012 / 0049025) will be described. In the prior art, the structure is as follows: an arc-shaped recess with a large radius of curvature is formed on the rear end side of the upper and lower claws, and an arc-shaped recess with a small radius of curvature is formed on the front end side of the upper and lower claws.
[0127] In the existing structure, when the rod is gripped using the recesses on the front end sides of the upper and lower jaws, the gripping position is further away from the center of gravity of the clamp compared to when the recesses on the rear end sides are used. Therefore, when the rod is gripped using the recesses on the front end sides of the upper and lower jaws, the torque acting on the engagement portion between the recess and the rod (the torque generated by the weight of the clamp itself or the mass of the clamp's retainer) tends to increase, making it difficult to grip the rod stably. Especially when gripping a horizontal rod, the clamp tends to rotate relative to the rod.
[0128] In contrast, in the fixture 1 of this embodiment, as... Figure 4 As shown, the upper clamping surface 250 formed between the rear end 250e and the front end 250f of the upper clamping surface 250 is located above the front and rear ends 250e and 250f of the upper clamping surface 250 (when an imaginary line connecting the front and rear ends 250e and 250f of the upper clamping surface 250 is drawn in a side view, the entire upper clamping surface 250 is located above the imaginary line).
[0129] Furthermore, the lower clamping surface 40, formed between its rear end 40c and front end 40d, is located further below its front and rear ends 40c and 40d (in a side view, if an imaginary line connecting the front and rear ends 40c and 40d of the lower clamping surface 40 is drawn, the lower clamping surface 40 is located further below the imaginary line). That is, in this embodiment, instead of arranging the recesses corresponding to the diameter of the rod in the front and rear as in the prior art, the upper and lower clamping surfaces 250 and 40 are used as a whole to clamp rods 200 to 400 with different diameters.
[0130] Furthermore, in a side view (left-right view) of the fixture 1, if the imaginary line connecting the front end 250f of the upper fixture surface 250 to the upper end 250g of the rear end side (a position further back than the center in the front-rear direction) of the upper fixture surface 250 is taken as imaginary line V2, and the imaginary line connecting the front end 40d of the lower fixture surface 40 to the lower end 40f of the rear end side (a position further back than the center in the front-rear direction) of the lower fixture surface 40 is taken as imaginary line V3, the interval between imaginary lines V2 and V3 gradually narrows towards the front side. That is, the structure becomes such that, except for the area where the small-diameter fixture surface 250c or the protrusion 40e is formed, the interval between the upper and lower fixture surfaces 250 and 40 gradually narrows from the rear end side towards the front end side.
[0131] If this is the structure, such as Figure 5 As shown in (a), when clamping a rod 200 with a larger diameter, the rod 200 can be clamped using two points: the rear end 250e of the upper clamping surface 250, the rear end 40c of the lower clamping surface 40, and the front end 250f and 40d side portions. The so-called front end 250f and 40d side portions are, for example, the front clamping surface 250d in the upper clamping surface 250, and the front end portion of the large diameter clamping surface 40b in the lower clamping surface 40.
[0132] Furthermore, in this embodiment, since the front surface 210 of the vertically extending sidewall 21 (frame 2) is formed on the rear side of the vertical clamping surfaces 250, 40 (the front surface 210 is located further forward than the pivot 5), the front surface 210 of the sidewall 21 can be used to clamp the rod 200 in addition to the two points mentioned above, depending on the diameter of the rod 200.
[0133] In addition, such as Figure 5 As shown in (b), when clamping a rod 300 with a diameter smaller than rod 200, the rod 300 can be clamped using two points: the rear end 250e of the upper clamping surface 250, the 40c of the lower clamping surface 40, and a portion closer to the center in the front-rear direction (a portion closer to the rear end than when clamping rod 200). The portion closer to the center in the front-rear direction is, for example, the front end of the large-diameter clamping surface 40b in the upper clamping surface 250, and approximately the center of the large-diameter clamping surface 40b in the front-rear direction in the lower clamping surface 40.
[0134] In addition, such as Figure 6 As shown in (a), when clamping a rod 400 with a diameter smaller than that of rod 300, the rod 400 can be clamped using the rear end of the large-diameter clamping surface 250b of the upper clamping surface 250 or the rear clamping surface 40a (the rear end of the large-diameter clamping surface 40b) of the lower clamping surface 40. That is, compared to clamping rod 300, the rod 400 can be clamped using the rear end portions of the upper and lower clamping surfaces 250 and 40.
[0135] Thus, in this embodiment, the spacing between the upper and lower clamping surfaces 250 and 40 gradually narrows from the rear end to the front end. Therefore, regardless of the difference in diameter between rods 200 and 400, rods 200 and 400 can always be clamped using the rear end portion of the upper and lower clamping surfaces 250 and 40 (the position close to the center of gravity of clamp 1). Therefore, compared to the prior art structure that arranges recesses with different radii of curvature one after the other, even when clamping rods 300 and 400 with smaller diameters, the torque acting on the engaging portion of rods 300 and 400 with the upper and lower clamping surfaces 250 and 40 is not easily increased. Therefore, clamp 1 can be stably installed on rods 200 and 400 with different diameters.
[0136] Furthermore, the lower clamping surface 40 (rear clamping surface 40a or large-diameter clamping surface 40b) is formed of an elastic body 4 that is more flexible than the upper jaw 25 or the lower jaw 3, so the lower clamping surface 40 can easily fit closely along the outer peripheral surface of the rods 200 to 400. Therefore, the lower clamping surface 40 is less likely to slide relative to the rods 200 to 400, thus suppressing the rotation of the clamp 1 around the rods 200 to 400. Therefore, the clamp 1 can be stably mounted on the rods 200 to 400.
[0137] Furthermore, a plurality of protrusions 40e are formed on the upper surface of the lower clamping surface 40 (large-diameter clamping surface 40b), thus making it less prone to sliding relative to the rods 200 to 400. In particular, in this embodiment, a plurality of protrusions 40e extending in the left-right direction are formed in a front-back direction, thus allowing the protrusions 40e extending axially along the rods 200 to 400 to be in close contact with the outer peripheral surfaces of the rods 200 to 400. As a result, sliding of the lower clamping surface 40 relative to the rods 200 to 400 can be more effectively suppressed, and the clamp 1 can be stably mounted on the rods 200 to 400.
[0138] In the prior art of the clamp described here (US Patent Application Publication No. 2012 / 0049025), since the upper and lower jaws face each other in the vertical direction, the gap between the upper and lower recesses is narrowest when these jaws are brought into contact with each other. In this state, the diameter of the rod that can be clamped becomes the smallest, thus easily limiting the diameter of the rod that can be clamped using the upper and lower recesses.
[0139] In contrast, the clamp 1 of this embodiment includes a pair of upper jaws 24, 25 spaced apart from each other (upper jaw 24 refers to...). Figure 1 ),like Figure 6 As shown in (a), when the gap between the upper jaws 24 and 25 and the lower jaw 3 narrows, the lower clamping surface 40 (elastic body 4) can pass through the gap between the pair of upper jaws 24 and 25. This allows the front ends of the upper and lower clamping surfaces 250 and 40 to intersect, thus enabling the clamping of rods 400 with smaller diameters to be held using the upper and lower clamping surfaces 250 and 40. Therefore, the clamp 1 can be installed on rods 200 to 400 of various diameters.
[0140] In addition, Figure 6 In (a), an example is shown where the upper portion of the elastomer 4 passes through the gap between the left and right upper claws 24 and 25, by means of... Figure 6 The state shown in (a) further narrows the gap between the upper jaws 24 and 25 and the lower jaw 3, allowing the lower jaw 3 to pass through the gap between the left and right upper jaws 24 and 25. That is, the upper and lower clamping surfaces 250 and 40 can also be used to clamp rods with a diameter smaller than that of the rod 400.
[0141] Furthermore, considering the torque acting on the engagement portion of the upper and lower clamping surfaces 250, 40 and the rod 400 as described above, it is preferable to clamp the rod 400 using the rear end portion of the upper and lower clamping surfaces 250, 40. On the other hand, if such torque is not a concern, such as Figure 6 As shown in (b), the rod 400 can also be clamped using the small-diameter clamping surface 250c. Therefore, the mounting position (relative position) of the clamp 1 relative to the rod 400 can be changed according to the purpose, thus improving the versatility of the clamp 1.
[0142] Then, referring to Figure 7 of (a) Figure 7 (b) describes the structure of the ring 500 or wooden ring 600 used to hold the electronic drum through the upper and lower clamping surfaces 250 and 40. Figure 7 (a) is a cross-sectional view of the clamp 1 showing the state of the clamping ring 500. Figure 7 (b) is a cross-sectional view of the clamp 1 showing the state of holding the wooden ring 600.
[0143] like Figure 7 As shown in (a), ring 500 is an annular component used to apply tension to the faceplate 501 of the electronic drum. Ring 500 includes an outer peripheral portion 500a disposed on the outer peripheral side (arrow B side) of the faceplate frame 502, and a pressing portion 500b extending vertically (arrow UD direction) from the upper end of the outer peripheral portion 500a and bending inward (arrow F side). The pressing portion 500b is a portion used to push the faceplate frame 502 downward, and an upright portion 500c stands upright from the inner peripheral end of the pressing portion 500b.
[0144] The inclined portion 500d rises and slopes upwards from the upper end of the upright portion 500c toward the outer periphery. These portions 500a to 500d constituting the ring 500 are integrally formed using metal or the like. When the clamp 1 is installed on this type of ring 500, the outer periphery 500a and the inclined portion 500d of the ring 500 are clamped by the small-diameter clamp surface 250c of the upper clamp surface 250 and the large-diameter clamp surface 40b of the lower clamp surface 40.
[0145] Thus, by utilizing the small-diameter clamping surface 250c, whose radius of curvature is smaller than that of the large-diameter clamping surface 250b, the ring 500 can be stably clamped via the upper and lower clamping surfaces 250 and 40. That is, except for the aforementioned rods 200 to 400 (refer to...) Figure 5 of (a) Figure 5 (b) and Figure 6 of (a) Figure 6 In addition to (b), clamp 1 can also be stably mounted on ring 500.
[0146] Furthermore, since the lower clamping surface 40 (large diameter clamping surface 40b) is formed of an elastic body 4, the lower clamping surface 40 can be made in close contact with the lower surface of the outer peripheral portion 500a of the ring 500. As a result, the lower clamping surface 40 is less likely to slide relative to the ring 500 (outer peripheral portion 500a), and thus the clamp 1 can be stably mounted on the ring 500.
[0147] Furthermore, a plurality of protrusions 40e are formed on the upper surface of the lower clamping surface 40 (large-diameter clamping surface 40b), thus making it less likely for the lower clamping surface 40 to slide relative to the ring 500 (outer peripheral portion 500a). In particular, in this embodiment, a plurality of protrusions 40e extending in the left-right direction are formed in a front-back direction, thus making it easier for the protrusions 40e to come into close contact with the outer peripheral portion 500a extending circumferentially along the ring 500. As a result, the sliding of the lower clamping surface 40 relative to the ring 500 can be more effectively suppressed, and thus the clamp 1 can be stably mounted on the ring 500.
[0148] like Figure 7 As shown in (b), the wooden ring 600 is a ring-shaped component used to apply tension to the surface 601 of the electronic drum, and is made of wood with a rectangular cross-section. When the clamp 1 is installed on this rectangular wooden ring 600, a pair of lower surfaces 251, 252 (upper planes) formed on the front and rear end sides of the upper jaw 25 and a pair of upper surfaces 41, 42 (lower planes) formed on the front and rear end sides of the elastic body 4 are utilized.
[0149] The upper jaw 25 has a pair of lower surfaces 251 and 252 that are connected to the front and rear ends 250e and 250f of the upper clamping surface 250 and face downwards (orthogonal to the vertical direction). The elastic body 4 has a pair of upper surfaces 41 and 42 that are connected to the front and rear ends 40c and 40d of the lower clamping surface 40 and face upwards (orthogonal to the vertical direction).
[0150] Furthermore, a front surface 210 of a sidewall 21 (frame 2) extending vertically is formed on the rear side of the lower surface 251 of the upper claw 25 and the upper surface 41 of the elastic body 4 (lower claw 3). With this structure, the rectangular wooden ring 600 can be held by clamping the wooden ring 600 between the upper and lower claws 25 and 3 using the pair of lower surfaces 251 and 252 of the upper claw 25, the pair of upper surfaces 41 and 42 of the elastic body 4 (lower claw 3), and the front surface 210 of the sidewall 21.
[0151] The front surface 210 of the sidewall 21 is spaced apart to form a pair (see reference). Figure 1 Therefore, even if the clamp 1 causes the front ends of the upper and lower claws 25, 3 to rotate along the inner and outer circumferential surfaces of the wooden ring 600, this movement can be effectively limited by the pair of front surfaces 210. Thus, except for the rods 200 to 400 (see...), Figure 5 of (a) Figure 5 (b) and Figure 6 of (a) Figure 6 In addition to (b) or ring 500, clamp 1 can also be stably mounted on wooden ring 600.
[0152] Furthermore, the clamps in the prior art (US Patent Application Publication No. 2012 / 0049025) include a flat surface corresponding to the lower surface 251 of the upper jaw 25 or the upper surface 41 of the lower jaw 3, but do not include a surface corresponding to the lower surface 252 or the upper surface 42 as in this embodiment. Moreover, in the clamps of the prior art, a component (screw 204) corresponding to the pivot 5 of this embodiment protrudes from the frame. Such prior art clamps are difficult to stably clamp the wooden ring 600.
[0153] On the other hand, in this embodiment, the wooden ring 600 is stably clamped by the front surface 210 of the plane or sidewall 21 formed on the front and rear ends of the upper and lower claws 25 and 3 as described above, and the wooden ring 600 is clamped by the upper surface 41 and upper surface 42 of the elastic body 4. As a result, the upper surface 41 and upper surface 42 of the elastic body 4 can be closely connected along the inner (or outer) circumferential surface of the curved wooden ring 600, so the clamp 1 can be stably installed on the wooden ring 600.
[0154] The above description is based on the embodiments described, but the present invention is not limited to any of the embodiments described, and it is easy to deduce that various modifications and variations can be made without departing from the spirit of the present invention.
[0155] In the described embodiment, rods 200 to 400, ring 500, and wooden ring 600 are shown as examples of objects on which clamp 1 is mounted, but this is not a limitation. Clamp 1 may also be mounted on other components arranged around the electronic musical instrument (or around the device connected to the electronic musical instrument).
[0156] In the described embodiment, a device 100, such as a wireless adapter, is shown as an example of a retainer held by the clamp 1, but it is not limited to this. For example, the clamp 1 can hold objects other than the device 100, such as accessories (peripheral devices) used in electronic musical instruments. In addition, the clamp 1 can hold two or more retainers, or the retainers can be held on the side of the frame 2.
[0157] In the described embodiment, the following situation is explained: a retaining portion 26 is formed on the clamp 1 side, and engaging portions such as sliding pieces 103a, sliding pieces 103b, or hooks 105 that hook onto the retaining portion 26 are formed on the device 100 side, but this is not necessarily limited to this. For example, a portion corresponding to the retaining portion 26 may be formed on the device 100 side, while engaging portions that hook onto the retaining portion 26 may be formed on the clamp 1 side.
[0158] Furthermore, in the described embodiment, the engaging portion that hooks onto the retaining portion 26 is formed on the frame of the device 100 itself. For example, it may also be structured such that an engaging part including the engaging portion is formed separately from the frame of the device 100, and the engaging part is subsequently installed on the device 100. That is, the device 100 holding method described in the embodiment is one example, and other known holding methods may also be used to hold the device 100 with the clamp 1.
[0159] In the described embodiment, the front surface 210 of the sidewall 21 is located further forward than the pivot 5 and the pivot 5 is not exposed further forward than the frame 2, but this is not necessarily the case. For example, the front surface 210 of one or both of the pair of sidewalls 21 may also be located further rearward than the front surface of the pivot 5.
[0160] In the described embodiment, the case where the interval between the upper and lower claws 24, 25, and 3 is adjusted by moving the lower claw 3 up and down is explained, but it is not limited to this. For example, the upper claws 24 and 25 can be moved up and down, or the upper and lower claws 24, 25, and 3 can be moved up and down respectively.
[0161] In the described embodiment, the following situation is explained: the upper claws 24 and 25 are arranged in a pair with a gap between them, allowing the elastic body 4 (lower claw 3) to pass through the gap between the pair of upper claws 24 and 25, but this is not a limitation. For example, the structure may have one or more upper claws, or multiple lower claws 3 may be arranged in a left-right arrangement. Alternatively, the elastic body 4 (lower claw 3) may not be able to pass through the gap between the left-right arranged upper claws 24 and 25.
[0162] In the described embodiment, the case where a small-diameter clamping surface 250c is formed on the upper clamping surface 240 and the upper clamping surface 250 is explained, but it is not necessarily limited to this. For example, the structure may also be as follows: the small-diameter clamping surface 250c is omitted, and the large-diameter clamping surface 250b and the front clamping surface 250d are formed into an arc-shaped clamping surface (the small-diameter clamping surface 250c is along...). Figure 4 (Imaginary line V1 is embedded as shown). Alternatively, a surface corresponding to the small-diameter clamping surface 250c (the surface capable of clamping the outer periphery 500a of the ring 500) may be formed on the lower clamping surface 40. Alternatively, a clamping surface corresponding to the lower clamping surface 40 may be formed on the upper jaws 24 and 25, while a clamping surface corresponding to the upper clamping surfaces 240 and 250 may be formed on the lower jaw 3 (elastic body 4).
[0163] In the described embodiment, the lower clamping surface 40 is formed by an elastic body 4 fixed to the lower jaw 3, but this is not a limitation. For example, the lower clamping surface 40 may be formed by the upper surface of the lower jaw 3 instead of the elastic body 4, and the upper clamping surface 240 and upper clamping surface 250 may also be formed by the elastic body 4.
[0164] In the described embodiment, a plurality of left-right extending protrusions 40e are formed in a front-back arrangement on the upper surface of the lower clamping surface 40 of the elastic body 4, but this is not a limitation. For example, a plurality of front-back extending protrusions 40e may be formed in a left-right arrangement, or a plurality of protrusions 40e may be formed in a front-back arrangement extending in a direction inclined relative to the left-right direction. In addition, wrinkled protrusions 40e that do not have this directionality may be distributed on the upper surface of the lower clamping surface 40, or the protrusions 40e may be omitted.
[0165] In the described embodiment, the following is noted: the lower surfaces 251 and 252 of the upper claws 24 and 25, or the upper surfaces 41 and 42 of the elastic body 4, are planes orthogonal to the vertical direction, but are not necessarily limited to this. For example, some or all of the surfaces 251, 252, 41, and 42 may be inclined relative to the front-back direction, or may be formed by curved surfaces.
