Description

[Technical field]

[0001] The present invention relates to a fastening device used for fastening objects to each other, and to a fastening structure therefor. [Background technology]

[0002] Conventionally, it has been widely and generally practiced to attach a holder for holding a bottle or other object to a light vehicle or other object using an attachment device. Examples of such holders include the holder described in Patent Document 1 and the holder described in Patent Document 2. In the holder described in Patent Document 1, the holder is attached to the light vehicle by an attachment device having a clamping piece, making the attachment work easy. In addition, in the holder described in Patent Document 2, the holder is firmly attached to the light vehicle by screwing an attachment device having a clamp. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 10-071978 [Patent Document 2] Japanese Patent Application Publication No. 54-144633 Summary of the Invention [Problem to be solved by the invention]

[0004] The mounting device described in Patent Document 1 is easy to install, but there is a risk that the mounting device will come off and the held object will fall if an impact is applied to the object to which it is attached. On the other hand, the mounting device described in Patent Document 2 can prevent the mounting device from coming off, but since the mounting device is firmly attached, it takes time to install and remove, and is less convenient.

[0005] The present invention has been made to solve the above-mentioned problems, and its main object is to provide a mounting device that facilitates mounting and removal operations while, when mounted, can effectively prevent the device from coming off unintentionally. [Means for solving the problem]

[0006] The first configuration is an attachment device comprising a main body having an attachment part and an attached part which can be attached to each other by moving them relative to each other in an opposing direction, a movable piece which extends in the opposing direction and is elastically deformable, and an abutment part which is provided on the movable piece and which can abut the attached part from the opposite side of the opposing direction when the attachment part is attached to the attached part, thereby restricting movement of the attached part, and an operating member which is assembled to the main body and is movable in the opposing direction and the opposite direction, wherein the abutment part is displaceable from an abutment position where it abuts the attached part to a non-abutment position where it does not abut the attached part, due to elastic deformation of the movable piece, and the operating member presses the movable piece as it moves in the opposing direction and the opposite direction, causing the abutment part to elastically deform to the non-abutment position.

[0007] In the first configuration, the direction of movement of the operating member is the same as the direction of the attachment operation between the attachment part and the attached part, so that the attachment and removal operations are easy to recognize and can be performed more easily, and the abutment part can prevent the attached part from being unintentionally removed.

[0008] In the second configuration, in addition to the first configuration, the main body is provided with a displacement portion that contacts the attached portion and moves the abutment portion to the non-abutment position when the mounting portion and the attached portion are moved relative to each other.

[0009] In the second configuration, the abutment portion is displaced to the abutted position by performing a relative movement operation between the mounting portion and the mounted portion, so there is no need to perform a separate operation to displace the abutment portion to the abutted position, and the mounting portion can be easily attached to the mounted portion.

[0010] In a third configuration, in addition to the first or second configuration, the main body and the operating member are provided with a display unit that indicates whether the operating member is pressing the movable piece by aligning them with each other.

[0011] In the third configuration, it is possible to determine whether the operating member is pressing the movable piece by visually checking the display unit, so that it is easy to determine whether the position of the abutment part is in the abutting position or the abutted position.

[0012] In a fourth configuration, in addition to the third configuration, the display portions of the main body and the operating member are through holes penetrating in a direction perpendicular to the opposing direction, and the ends of the through holes in the opposing direction are aligned to indicate whether the operating member is pressing the movable piece.

[0013] In the fourth configuration, whether or not the operating member is pressing the movable piece is indicated by the coincidence of the ends of the through holes, so that the pressing state of the operating member can be determined with a simple configuration.

[0014] The fifth configuration is, in addition to the first or second configuration, such that the movable piece has a tip end on the side in the opposing direction and a base end on the side opposite the opposing direction, and the operating member presses a position of the movable piece closer to the base end.

[0015] In the fifth configuration, even if the amount of pressure applied to the movable piece is small, the amount of displacement of the tip of the movable piece can be made large, so that the amount of operation of the operating body can be made smaller.

[0016] In the sixth configuration, in addition to the first or second configuration, the main body includes a biasing portion that biases the operating member in a direction opposite to the direction that elastically deforms the abutment portion to the abutted position.

[0017] In the sixth configuration, the biasing portion biases the operating member in a direction that does not elastically deform the abutment portion, thereby preventing the operating member from unintentionally pressing the movable piece and moving the abutment portion to the abutted position, thereby effectively preventing unintentional detachment of the attached portion.

[0018] The seventh configuration, in addition to the first configuration, is such that when the mounting portion is attached to the mounting portion, the mounting portion and the mounted portion can rotate relatively around a rotation axis in a direction perpendicular to the opposing direction.

[0019] When attaching two articles using a mounting device, if the posture of one article changes, the posture of the other article may also change accordingly, which may cause inconvenience. In this regard, in the seventh configuration, even if the posture of one article changes, the posture of the other article can be maintained in a suitable position by changing the relative angle between the mounting portion and the mounted portion.

[0020] The eighth configuration includes, in addition to the seventh configuration, a rotation range restriction portion that restricts the angle at which the mounting portion and the mounted portion can rotate relative to each other.

[0021] In cases where the mounting part and the attached part are made rotatable relative to one another, if the rotation angle of the other article is excessive, inconvenience may occur. In this regard, the eighth configuration is provided with a rotation range restriction part, so that the relative rotation range of the mounting part and the attached part can be set to a range that does not cause inconvenience to the other article.

[0022] A ninth configuration includes, in addition to the seventh or eighth configuration, a rotation suppressing portion that suppresses relative rotation between the mounting portion and the mounted portion.

[0023] In the ninth configuration, since the relative orientation of the articles attached using the attachment device can be maintained, it can be used while suppressing rotation when rotation is not necessary.

[0024] The tenth configuration is, in addition to the first configuration, that the mounting portion is removably provided with respect to the main body, and when the mounted portion is attached to the mounting portion, the mounting portion and the mounted portion slide relative to each other.

[0025] If the mounting part and the attached part slide relative to each other when they are attached to each other, the lower the coefficient of friction between them, the better, but if the mounting part and the main body are manufactured as a single unit, the optimum coefficient of friction is not necessarily selected, taking into consideration the strength, elasticity, cost, etc. of the other components. In this regard, in the tenth configuration, the mounting part is detachable from the main body, so that a material with a low coefficient of friction with the attached part can be preferentially selected, and if it becomes worn due to sliding, it can be removed and replaced.

[0026] An eleventh configuration is an attachment structure comprising a main body having an attachment portion and an attached portion which can be attached to each other by moving them relative to each other in an opposing direction, a movable piece which extends in the opposing direction and is elastically deformable, and an abutment portion which is provided on the movable piece and which can abut against the attachment portion from the opposite side of the opposing direction when the attachment portion is attached to the attached portion, thereby restricting movement of the attached portion, and an operating member which is assembled to the main body so as to be movable in the opposing direction and in the direction opposite to the opposing direction, wherein the abutment portion is displaceable from an abutment position where it abuts against the attached portion to a non-abutment position where it does not abut against the attached portion, due to elastic deformation of the movable piece, and the operating member presses the movable piece as it moves in the opposing direction and the opposite direction, causing the abutment portion to elastically deform to the non-abutment position.

[0027] The eleventh configuration provides effects equivalent to those of the mounting device of the first configuration. [Brief description of the drawings]

[0029] <Embodiment> The holder 10 according to this embodiment is attached to an object such as an arm support of a wheelchair and can accommodate a container of a beverage or the like, which is the object to be held, in the internal space. In the following description, the side of the holder 10 that is attached to the wheelchair is defined as the back side, and the top-bottom direction when the holder 10 is attached to the wheelchair is defined as the up-down direction.

[0030] The holder 10 includes a receiving portion 20 provided at the lower end side of the entire holder 10, and a side support portion 30 provided above the receiving portion 20. The receiving portion 20 and the side support portion 30 are integrally molded from an elastically deformable resin. The receiving portion 20 is composed of a cylindrical side wall 21 having a substantially uniform thickness, and a bottom surface 22 provided at the lower end of the side wall 21 and closing the lower end of the side wall 21. Since the receiving portion 20 is configured in this manner, it can be said that the entire receiving portion 20 has a bottomed cylindrical shape, and that a columnar internal space is formed inside the receiving portion 20. The diameter of the side wall 21 is slightly larger than the height of the side wall 21.

[0031] The side support portion 30 has a plurality of arms 31 standing upward from the upper end of the side wall 21 of the receiving portion 20. There are 13 arms 31, each of which has an approximately equal shape and is slightly higher than the height of the side wall 22 of the receiving portion 20. The arms 31 are spaced apart at equal intervals in the circumferential direction, and the circumferential width of each arm 31 is greater than the interval between the arms 31. Since the arms 31 are arranged in this manner, the area surrounded by the arms 31 can be said to form a cylindrical internal space that is continuous with the inside of the receiving portion 20 in the up-down direction, and each arm 31 can be said to be elastically deformable inward and outward from the internal space.

[0032] An inclined portion 32 that is inclined outward, i.e., toward the side opposite the internal space, is provided at the upper end of the arm portion 31. A positioning portion 33 that is recessed in a semicircular cross section from the outside to the inside is formed at the boundary between the inclined portion 32 and the arm portion 31 over the entire width direction.

[0033] The rubber band 34 in the shape of a ring is attached to surround the outer periphery of the positioning portion 33 provided on the arm 31 of the side support portion 30 configured as described above. The inner diameter of the rubber band 34 may be equal to or smaller than the outer diameter of the portion of the arm 31 where the positioning portion 33 is formed. If the inner diameter of the rubber band 34 is equal to the outer diameter of the positioning portion 33, the rubber band 34 will be elastically deformed and expanded when attached, but will not be elastically deformed when positioned around the positioning portion 33. If an outward force is applied in this state so that the arm 31 expands in diameter, the rubber band 34 will be elastically deformed and expanded in diameter. On the other hand, if the inner diameter of the rubber band 34 is smaller than the outer diameter of the positioning portion 33, the arm 31 will be elastically deformed toward the inside of the internal space when the rubber band 34 is attached around the positioning portion 33. At this time, the restoring force of the arm 31 elastically deformed toward the inside of the internal space and the restoring force of the rubber band 34 with the expanded diameter are maintained in a balanced state. Since the rubber band 34 is attached to the arm portion 31 in the manner described above, the rubber band 34 can be called a diameter-reducing member that is elastically deformable in the inward and outward directions of the internal space.

[0034] The rear side of the holder 10 is provided with a holding portion 40 that stands upward. The holding portion 40 protrudes rearward from the receiving portion 20 of the holder 10 and includes a plate-shaped bottom portion 41 having a uniform thickness in the up-down direction, a plate-shaped right side portion 42 that stands upward from the right end of the bottom portion 41 and has a uniform thickness in the left-right direction, a plate-shaped left side portion 43 that stands upward from the left end of the bottom portion 41 and has a uniform thickness in the left-right direction, and a plate-shaped rear portion 50 that stands upward from the rear end of the bottom portion 41 and has left and right ends connected to the right side portion 42 and left side portion 43, respectively. In other words, the holding portion 40 is substantially box-shaped with the bottom portion 41, the right side portion 42, the left side portion 43, and the rear portion 50 opening upward and in the front.

[0035] The bottom 41 is integrally molded so as to protrude rearward from approximately the middle position of the side wall 21 in the up-down direction, and its left-right width is smaller than that of the side wall 21, while its front-to-rear width is approximately half of that width. In addition, since the front end of the bottom 41 is integrally molded with the side wall 21, it has an arc shape that curves rearward along the shape of the outer circumferential surface of the side wall 21.

[0036] The height of the right side surface portion 42 is slightly higher than the positioning portion 33 provided on the arm portion 31, but does not reach the upper end of the arm portion 31. The right side surface portion 42 has a substantially constant front-to-rear width up to a position slightly above the upper end of the side wall 22, and above that position, the rear end stands vertically upward and the front end is inclined backward, so that the front-to-rear width gradually decreases upward. The shape of the left side surface portion 43 is the same as that of the right side surface portion 42, so a description thereof will be omitted.

[0037] Next, the structure of the rear part 50 will be described with reference to Figs. 8 to 12. Although Figs. 8 to 12 show configurations corresponding to parts of the left and right side parts 42, 43, their description and reference numerals are omitted. The rear part 50 is a plate-like structure erected upward, and its height is higher than the combined height of the receiving part 20 and the side support part 30. The upper end of the rear part 50 is substantially trapezoidal, and a first through hole 51 is provided below the upper end with a slight gap. The first through hole 51 has an outer shape defined by a pair of parallel straight lines on the left and right and a semicircular arc connecting the upper ends of the straight lines, and is an ellipse with its major axis extending in the vertical direction. A pair of rail parts 52 are provided near the left and right sides of the front side of the first through hole 51, protruding toward the front and extending vertically. The upper ends of the pair of rail parts 52 are slightly above the upper end of the first through hole 51, and the lower ends are slightly below the lower end of the first through hole 51. The pair of rail parts 52 have a uniform amount of protrusion toward the front in the entire vertical direction, and the left-right interval is constant. The left-right width of each rail part 52 is uniform up to the vicinity of the front end on the front side, and the front end of each rail part 52 is provided with a protruding part 53 that protrudes toward the opposing direction of the rail parts 52. The protruding amount of the front end of the protruding part 53 is approximately uniform in the vertical direction, and the protruding amount is an amount that does not overlap with the first through hole 51. A cylindrical locking protrusion 54 that protrudes toward the rear is provided below the rear side of the first through hole 51. The height of this locking protrusion 54 is slightly smaller than the protruding amount of the rail part 52 provided on the front side.

[0038] Below the first through hole 51, a rectangular opening 55 extending in the vertical direction is provided. The left-right central axis of this opening 55 is approximately the same as the left-right central axis of the back part 50, and the position of the opening 55 in the vertical direction is located approximately at the center of the entire back part 50. The left-right width of the opening 55 is approximately equal to the left-right distance between the rail parts 52. A movable piece 61 is provided so as to stand upward from the lower end of the opening 55. The shape of this movable piece 61 is a rectangular plate extending in the vertical direction that is approximately similar to the opening 55. The thickness of the movable piece 61 is equal to the thickness of the back part 50 until it reaches the vicinity of the upper end, and a displacement part 62 having a slope that protrudes backward is provided so that the thickness gradually increases from the vicinity of the upper end to the upper end. On the other hand, there is no slope on the front side of the movable piece 61, and it forms a flat surface that approximately coincides with the front of the back part 50. In addition, an arc-shaped abutment part 63 that is recessed downward is formed on the upper end edge of the displacement part 62.

[0039] From a position slightly below the center in the vertical direction of the movable piece 61 to the vicinity of the lower end, rectangular slits 64 are formed on the left and right sides so that the width narrows. The slits 64 have the same width, and the vertical positions and lengths are also equal. A biasing portion 65 is provided at the upper end of the slit 64 of the movable piece 61, which is formed slightly thinner than other parts of the movable piece 61 and has a slope that gradually increases in thickness toward the top. The biasing portion 65 is provided up to approximately the center in the vertical direction of the movable piece 61. The slope of the biasing portion 65 is provided on the back side, and the front surface of the biasing portion 65 forms a plane that is equal to the front surface of the movable piece 61.

[0040] The rear part 50 configured as above is used with the operation member 70 attached thereto. The structure of the operation member 70 will be described with reference to Figs. 13 to 15. The operation member 70 includes a rectangular plate part 71 extending in the up-down direction. The left-right width of the plate part 71 is approximately equal to the left-right interval of the rail part 52 provided on the front side of the rear part 50. That is, it is also approximately equal to the left-right width of the opening 55 of the rear part 50. The front-rear thickness of the plate part 71 is approximately equal to the interval between the front of the rear part 50 and the rear of the overhang part 53 provided on the rail part 52. A second through hole 72, which is a circular hole, is provided near the upper end of the plate part 71. The center of the second through hole 72 is located in the center of the plate part 71 in the left-right direction, and the diameter of the second through hole 72 is approximately equal to the diameter of the semicircular arc that defines the upper and lower outer shapes of the first through hole 51.

[0041] A pair of legs 73 extending vertically downward is provided on the left and right sides of the lower end of the plate portion 71. The left and right widths of the legs 73 are substantially uniform in the vertical direction and are substantially equal to the distances between the left and right ends of the opening 55 and the left and right ends of the movable piece 61. A pressing portion 74 is provided protruding from the back surface of the lower end of each leg 73, and has a larger left and right width than the legs 73 and is substantially equal to the left and right width of the notch 64. The left end of the pressing portion 74 provided at the lower end of the left leg 73 forms a straight line common to the left end of the leg 73, and the right end of the pressing portion 74 provided at the lower end of the right leg 73 forms a straight line common to the right end of the leg 73. That is, the pressing portions 74 protrude in the opposite directions. The back surface of the pressing portion 74 is a flat surface that stands vertically in the vertical direction, and the front side is inclined so that the thickness gradually increases from the upper end to the lower end. Furthermore, the length from the lower end of the second through hole 72 to the lower end of the leg portion 73 is approximately equal to the length from the lower end of the first through hole 51 in the back surface portion 50 to the lower end of the notch 64 .

[0042] The mounting portion 80 is attached to the rear side of the rear portion 50 so as to cover the vicinity of the upper end of the movable piece 61 from slightly below the first through hole 52. The mounting portion 80 has a curved wall-shaped peripheral wall portion 81 that stands in the front-rear direction. The upper end side of the peripheral wall portion 81 is semicircular, and is configured to expand slightly outward from each of the lower ends of the semicircular arc. In other words, the shape of the peripheral wall portion 81 in rear view can also be called an inverted U-shape that opens downward so as to expand outward. The curvature of the semicircular arc on the upper end side of the peripheral wall portion 81 is approximately equal to the curvature of the abutment portion 63 provided on the movable piece 61.

[0043] An inner flange 82 is provided at the rear end of the peripheral wall 81, the width of which increases toward the inside of the peripheral wall 81. The thickness of the inner flange 82 in the front-rear direction is substantially uniform over the entire circumference, and the width of the inner flange 82 in the circumferential direction is also substantially uniform over the entire circumference. On the other hand, an outer flange 83 is provided at the front end of the peripheral wall 81, the width of which increases toward the outside of the peripheral wall 81. The thickness of the outer flange 83 in the front-rear direction is substantially uniform over the entire circumference, and the width of the outer flange 83 in the circumferential direction is not uniform, with the left and right ends extending in the vertical direction to form a pair of parallel sides, and the upper end forming a side extending horizontally in the left-right direction. The mounting part 80 configured as described above is removably attached to the rear part 50 by screwing a screw 84 into the outer flange 83.

[0044] The mounting portion 90 is attached to the rear portion 50 configured as above and used. The shape of the mounting portion 90 will be described with reference to Figs. 16-20. The mounting portion 90 is composed of a first disk portion 91 having a thickness in the front-rear direction, a second disk portion 93 having a thickness substantially equal to that of the first disk portion 91 and a diameter slightly smaller than that of the first disk portion 91, and a disk-shaped connecting portion 92 connecting the first disk portion 91 and the second disk portion 93. The first disk portion 91, the connecting portion 92, and the second disk portion 93 share a central axis. The radius of the first disk portion 91 is equal to the radius of curvature of the contact portion 63 of the movable piece 61 and the upper end side of the peripheral wall 81 of the mounting portion 80. The thickness of the first disk portion 91 and the second disk portion 93 is slightly thinner than the distance between the rear surface of the rear portion 50 and the front surface of the inner flange 82 of the mounting portion 80. Further, the thickness of the connecting portion 92 in the front-rear direction, that is, the distance between the first circular plate portion 91 and the second circular plate portion 93, is approximately equal to the thickness of the inner flange 82 of the attachment portion 80.

[0045] A rotation range restricting portion 94 recessed toward the rear surface is provided on the front surface of the first disc portion 91. The rotation range restricting portion 94 is an arc-shaped groove along the outer periphery of the first disc portion 91 in a front view, and has an open upper end. The depth of the rotation range restricting portion 94 is approximately equal to the height of the locking protrusion 54 provided on the rear surface, and the vertical width is also approximately equal to the diameter of the locking protrusion 54. On the other hand, a rotation suppressing portion 95 recessed toward the rear surface is provided on the front surface of the first disc portion 91 at a position symmetrical about the center of the rotation range restricting portion 94. The rotation suppressing portion 95 is an approximately circular groove with an open lower end, and the depth is approximately equal to the height of the locking protrusion 54, and the diameter is also approximately equal to the diameter of the locking protrusion 54.

[0046] A circular mounting hole 96 that penetrates in the front-rear direction is provided on the central axis of the mounting portion 90 in the front-rear direction. A female screw can be provided inside this mounting hole 96, and this female screw can be used to mount the device to an arm support of a wheelchair. If the object to be mounted is not the arm support of a wheelchair, a suitable mounting method for the object to be mounted can be adopted using this mounting hole 96 and various known mounting means.

[0047] The above-described method of attaching the operating member 70 and the mounting portion 90 to the rear portion 50 and the method of using the operating member 70 will be described with reference to Figs. 21-27. The operating member 70 is attached by entering from below between the rail portions 52 provided on the front surface of the rear portion 50. The left-right width of the plate portion 71 of the operating member 70 is approximately equal to the left-right distance between the rail portions 52, and the thickness of the plate portion 71 is approximately equal to the distance between the front surface of the rear portion 50 and the rear surface of the overhang portion 53. Therefore, the left and right sides of the plate portion 71 of the operating member 70 are sandwiched between the rail portions 52, and the front and rear are sandwiched between the rear portion 50 and the overhang portion 53. Since the pressing portion 74 provided on the operating member 50 protrudes toward the rear surface, it enters the notch 64 of the movable piece 61, as shown in Fig. 24, and the inclined surface provided on the front side of the pressing portion 74 and the inclined surface provided on the biasing portion 65 of the movable piece 61 face each other with a slight gap between them. At this time, by making the outer periphery of the lower end of the second through hole 72 provided in the operating member 70 and the outer periphery of the lower end of the first through hole 51 provided in the rear surface portion 50 approximately coincide with each other in a rear view, it becomes possible to visually determine that the pressing portion 74 of the operating member 70 is not pressing the biasing portion 65.

[0048] The mounting portion 90 is attached by entering the space between the rear portion 50 and the mounting portion 80 from below. At this time, it is possible to attach the mounting portion 90 to the rear portion 50 and the mounting portion 80, or if the mounting portion 90 is attached to a structure or the like in advance, it is also possible to attach the mounting portion 80 to the rear portion 50 and the mounting portion 90. In other words, the mounting portion 90 enters the space between the rear portion 50 and the mounting portion 80 from below by relatively moving the rear portion 50, the mounting portion 80, and the mounting portion 90 in directions facing each other.

[0049] When the attached portion 90 is caused to enter from below the attachment portion 80, the front surface of the first disk portion 91 of the attached portion 90 is made to face the rear surface of the rear portion 50, and the attached portion 90 is caused to slide along the rear surface of the movable piece 61. At this time, when the attached portion 90 reaches the displacement portion 62 of the movable piece 61, as the attached portion 90 slides, the movable piece 61 is pressed toward the front surface and elastically deformed, as shown in FIG. 25, and the attached portion 90 passes through the rear side of the displacement portion 62 and the abutment portion 63 of the movable piece 61, and can enter between the rear portion 50 and the attachment portion 80.

[0050] When the attached portion 90 enters between the rear surface portion 50 and the attachment portion 80 from below, the front and rear surfaces of the first disc portion 91 of the attached portion 90 are sandwiched between the rear surface portion 50 and the attachment portion 80. The inner flange 82 of the attachment portion 80 fits between the first disc portion 91 and the second disc portion 93 of the attached portion 90. At this time, the inner flange 82 slides against the rear surface of the first disc portion 91, the outer peripheral surface of the connecting portion 92, and the front surface of the second disc portion 93, and the attached portion 90 moves while sliding against the attachment portion 80 until it reaches the upper end edge of the attachment portion 80. In addition, when the attached portion 90 has passed the rear surface of the movable piece 61, the elastically deformed movable piece 61 returns to its original shape, and the abutment portion 63 provided at the upper end of the movable piece 61 abuts against the lower end edge of the attached portion 90. This prevents the attached portion 90 from coming off downward.

[0051] In the manner described above, when inserting the mounted portion 90 between the rear portion 50 and the mounting portion 80, whether or not the mounted portion 90 can be swung can be selected by directing either the rotation range restricting portion 94 or the rotation suppressing portion 95 provided on the first circular plate portion 91 of the mounted portion 90 upward. That is, if the rotation range restricting portion 94 is directed upward, the locking protrusion 54 provided on the rear portion 50 fits into the rotation range restricting portion 94, and if the rotation suppressing portion 95 is directed upward, the locking protrusion 54 fits into the rotation suppressing portion 95.

[0052] When the locking projection 54 is fitted into the rotation range restricting portion 94, the relative movement between the mounting portion 80 and the mounted portion 90 in the up, down, left and right directions is restricted, so that the mounting portion 80 and the mounted portion 90 can rotate relatively around the central axis, and the swingable angle is an angle according to the length of the rotation range restricting portion 94. On the other hand, when the locking projection 54 is fitted into the rotation restricting portion 95, the relative rotation between the mounting portion 80 and the mounted portion 90 is restricted. In other words, if a method of use in which the entire holder 10 is required to swing around the central axis of the mounted portion 90 is required, the mounted portion 90 is fixed so that the rotation range restricting portion 94 faces upward, and if it is required that the entire holder 10 not swing, the mounted portion 90 is fixed so that the rotation restricting portion 95 faces upward.

[0053] When removing the attached portion 90 attached as described above, the operating member 70 is pulled upward. Specifically, a finger is inserted into the first through hole 51 of the rear portion 50 and the second through hole 72 of the operating member 70 and pulled up so that the upper edge of the first through hole 51 and the upper edge of the second through hole 72 are approximately aligned. At this time, the inclined surface of the pressing portion 74 provided on the lower end side of the operating member 70 is pulled upward while abutting against the inclined surface of the biasing portion 65 of the movable piece 61, so that the biasing portion 65 is pressed by the pressing portion 74. As a result, a force directed forward is applied to the vicinity of the base end of the movable piece 61, and the movable piece 61 is elastically deformed forward. Therefore, the abutting portion 63 of the movable piece 61 moves to a non-abutting position where it does not abut against the attached portion 90, and the attached portion 90 can move downward.

[0054] Regarding the position of the abutment portion 63 of the movable piece 61 described above, it can be determined whether it is in the abutment position or the non-abutment position by visually checking the second through hole 72 of the operating member 70. That is, when the operating member 70 is not pulled up and the position of the abutment portion 63 is in the abutment position, it can be visually confirmed that the lower edge of the second through hole 72 of the operating member 70 and the lower edge of the first through hole 51 of the rear surface portion 50 approximately coincide with each other, as shown in FIG. 21. On the other hand, when the operating member 70 is pulled up and the position of the abutment portion 63 is in the non-abutment position, it can be visually confirmed that the upper edge of the second through hole 72 of the operating member 70 and the upper edge of the first through hole 51 of the rear surface portion 50 approximately coincide with each other, as shown in FIG. In this manner, by visually checking the first through hole 51 and the second through hole 72, it is possible to determine whether the position of the abutment portion 63 is in an abutment position or a non-abutment position. Therefore, the first through hole 51 and the second through hole 72 can be collectively referred to as an indicator for making it possible to determine the position of the abutment portion 63.

[0055] After the attached portion 90 is removed, the operating member 70 is pulled down to release the pressing state of the pressing portion 74 against the biasing portion 65, and the movable piece 61 returns from the elastically deformed state, and the abutting portion 63 returns to the abutting position. At this time, the operating member 70 is pulled down as the movable piece 61 returns from the elastically deformed state, even without the need to operate the operating member 70 manually. Specifically, the elastically deformed movable piece 61 deforms to return from the elastically deformed state to its original state, and the biasing portion 65 is displaced toward the rear surface accordingly. At this time, the inclined surface of the biasing portion 65 presses the inclined surface of the pressing portion 74, and the pressing force moves the pressing portion 74 downward. That is, the pressing portion 74 is biased downward by the biasing portion 65, and the entire operating member 70 is pressed downward.

[0056] In addition, the above-described configuration of the back surface portion 50, the operating member 70, the mounting portion 80, and the mounted portion 90 is used when mounting the receiving portion 20 and the side support portion 30 to the mounting object, so that the whole can be collectively referred to as the mounting device, and the whole structure of the mounting device can also be referred to as the mounting structure. Also, the back surface member 50 can be referred to as the main body, and the main body includes the mounting portion 80 and the mounted portion 90, and the operating member is further attached to the main body for use.

[0057] With the above-described configuration, the holder according to this embodiment provides the following advantages.

[0058] Since the shapes of the arms 31 and the rubber bands 34 change according to the shape of the object to be held, the object can be held appropriately regardless of the shape of the object. When some of the arms 31 elastically deform while holding the object, the rubber bands 34 also elastically deform in response to the elastic deformation, and the other arms 31 also elastically deform due to the elastic deformation of the rubber bands 34. This makes it possible to prevent only some of the arms 31 from elastically deforming, and prevents the object from falling off due to the elastic deformation of only some of the arms 31.

[0059] When the diameter of the object to be held is larger than the diameter of the side support parts 21, the arms 31 elastically deform outward to support the object to be held, and in this case the rubber bands 34 also elastically deform outward following the elastic deformation of the arms 31. Therefore, the rubber bands 34 and the arms 31 work together to hold the object to be held, so that even if the diameter of the object to be held is larger than the diameter of the side support parts 30, the object to be held can be stably held.

[0060] When attaching the rubber band 34 to the arm portion 31, if the rubber band 34 moves toward the upper end, the amount of deformation at the upper end of the arm portion 31 decreases, and if the rubber band 34 moves toward the lower end, the amount of deformation at the upper end of the arm portion 31 increases. In this regard, by providing the positioning portion 33 on the arm portion 31 in the embodiment, the vertical movement of the rubber band 34 can be suppressed, and the amount of deformation of the arm portion 31 caused by the rubber band 34 can be kept constant.

[0061] Since the vertical height of the arm 31 is greater than the height of the wall 22 that constitutes the receiving portion 20, the length of the arm 31 that can elastically deform can be made longer, and the amount of deformation of the tip of the arm 31 can be adjusted to a greater extent by the rubber band 34.

[0062] Since the holder 10 can be attached to the object by utilizing the rotatable mounting portion 90, the object can be held while maintaining the up-down orientation of the holder 10. Therefore, even if the object is tilted, the up-down orientation of the holder 10 can be aligned with the top-bottom direction, and the object can be stably held.

[0063] The operation direction of the operating member 70 is the up-down direction, which is the same direction as the operation direction when attaching the attached portion 90 to the attachment portion 80. Therefore, the attachment and detachment operations are easy to recognize and can be performed more easily.

[0064] Since the abutment portion 63 is displaced to the abutted position by moving the mounting portion 90, there is no need to perform a separate operation to displace the abutment portion 63 to the abutted position, and the mounting portion 80 can be easily attached to the mounting portion 90.

[0065] By visually checking the positional relationship between the first through hole 51 and the second through hole 72, it is possible to determine whether the operating member 70 is pressing the movable piece 61, and therefore it is easy to determine whether the position of the abutment portion 63 is in the abutting position or the abutted position.

[0066] Since the pressing portion 74 of the operating member 70 presses the base end of the movable piece 61, the amount of displacement of the tip of the movable piece 61 can be made large even if the amount of pressure applied to the movable piece 61 is small, and therefore the amount of operation of the operating member 70 can be made smaller.

[0067] The biasing portion 65 biases the operating member 70 in a direction that does not elastically deform the abutment portion 63, thereby preventing the operating member 70 from unintentionally pressing the movable piece 61 and moving the abutment portion 63 to the abutted position, thereby making it possible to effectively prevent the attachment portion 90 from unintentionally coming off.

[0068] Even if the posture of the structure to which the attached portion 90 is attached changes, the posture of the receiving portion 20 and the side support portion 30 can be maintained vertically by changing the relative angle between the attachment portion 80 and the attached portion 90, and the drop of the held object can be prevented. In addition, if the relative rotation angle between the attachment portion 80 and the attached portion 90 is excessive, there is a risk of the held object dropping due to excessive rotation, but since the rotation range restricting portion 94 is provided, the relative rotation range between the attachment portion 80 and the attached portion 90 can be restricted to a degree that does not cause the held object to fall. In addition, by restricting the relative swing between the attachment portion 80 and the attached portion 90 using the swing suppressing portion 95, the relative posture between the attachment portion 80 and the attached portion 90 can be maintained when relative swing is not required.

[0069] If the mounting part 80 and the mounted part 90 slide relative to each other when mounting the mounting part 80 to the mounted part 90, the coefficient of friction between the mounting part 80 and the mounted part 90 is preferably small, but if the mounting part 80 and the back part 50 are manufactured as a single unit, the optimum coefficient of friction is not necessarily selected in consideration of the strength, elasticity, cost, etc. of the other components. In this regard, in this embodiment, since the mounting part 80 is detachable from the main body, a material with a small coefficient of friction with the mounted part 90 can be preferentially selected, and if it becomes worn due to sliding, it can be removed and replaced. <Modification>

[0070] Regarding the rubber bands 34 in the embodiment, multiple rubber bands 34 with different diameters in a non-elastically deformed state may be selectable. Also, regarding the rubber bands 34, not only the diameter but also the thickness may be selectable. In this way, rubber bands 34 with different sizes can be selected according to the size and weight of the object to be held and attached to the arm portion 31. Also, regarding the rubber bands 34, not only the diameter but also the thickness may be selectable. In this case, too, by attaching rubber bands 34 with different diameters and thicknesses to a common positioning portion 33, the elastic force of the rubber bands 34 can be more suitably selected.

[0071] Instead of the rubber band 34, a C-shaped ring made of metal or resin may be attached to the arm portion 31 as a diameter reducing member.

[0072] A structure may be provided that allows a diameter-reducing member such as a rubber band 34 to be attached to the inside of the arm 31, or the diameter-reducing member may be attached by selecting the outside or inside. If the diameter-reducing member can be attached to the outside by selecting the outside or inside, the deformation amount of the arm 31 can be adjusted by attaching the member to the inside in case the diameter is excessively reduced when the member is attached to the outside.

[0073] In cases where the elasticity of the rubber bands 34 is small and the amount of deformation is insufficient when the rubber bands 34 are attached to the arm portion 31, the amount of deformation of the arm portion 31 may be adjusted by increasing the number of rubber bands 34 attached.

[0074] The diameter of the rubber band 34 may be selected to be approximately equal to the outer diameter of the arm 31. If an object to be held is selected whose outer diameter is larger than the outer diameter of the arm 31, the object to be held will cause the arm 31 to elastically deform outward. In this case, if the diameter of the rubber band 34 is set to be approximately equal to the outer diameter of the arm 31, the rubber band 34 will also elastically deform in response to the elastic deformation of the arm 31, and the rubber band 34 and the arm 31 can cooperate to hold the object to be held.

[0075] The positioning portion 33 may be provided at a plurality of positions in the extending direction of the arm portion 31. In this case, the deformation amount of the arm portion 31 can be adjusted by changing the position where the rubber band 34 is attached, and the position where the rubber band 34 is attached can be changed according to the size and weight of the object to be held.

[0076] The direction in which the attached portion 90 enters the attachment portion 80 does not have to be from below to above. In other words, it may enter from above to below, or from one side to the other in the left-right direction.

[0077] The base end of the movable piece 61 may be positioned upward and the tip end may be positioned downward, and the upper base end may be pressed.

[0078] In the embodiment, the displacement portion 62 is provided on the upper end side of the movable piece 61, but a configuration equivalent to the displacement portion 62 may be provided in another location on the back portion 50, and the contact portion 63 may be moved to the contact position by the attachment portion 90 coming into contact with that portion.

[0079] In the embodiment, the first through hole 51 and the second through hole 72 function as a display unit, and whether or not the operating member 70 is pressing the movable piece 61 is displayed by aligning the first through hole 51 and the second through hole 72, but the configuration for causing them to function as a display unit is not limited to this, and various means can be adopted. For example, a vertically long hole may be provided on one of the back surface portion 50 and the operating member 70, and a member or the like that can be viewed through the vertically long hole may be provided on the other, and the state of the operating member 70 may be confirmed by the position of that member.

[0080] The first through hole 51 and the second through hole 72 may be of equal size instead of different sizes. Even in this case, it is possible to determine whether or not the operating member 70 is in the pressed state based on whether or not the positions of the first through hole 51 and the second through hole 72 coincide with each other when visually observed.

[0081] Although the movable piece 61 extends from the bottom to the top, the top may be the base end and the bottom may be the tip. In this case, the abutment portion 63 is provided on the base end side of the movable piece 61, so that the amount of operation of the operating member 70 may be made larger in order to displace the movable piece 61 more, or the movable piece 61 may be structured to be able to deform more even when the amount of operation of the operating member 70 is small.

[0082] In the embodiment, the attached portion 90 is fixed to the attachment object side such as a wheelchair, and the movable piece 61, attachment portion 80, etc. provided on the receiving portion 20 and the side support portion 30 side rotate, thereby causing the attached portion 90 and the movable piece 61, attachment portion 80, etc. to rotate relatively to each other. In this regard, the movable piece 61, attachment portion 80, etc. may be fixed to the attachment object side, and the attached portion 90 may be provided on the receiving portion 20 and the side support portion 30 side, and the attached portion 90 may rotate relative to the movable piece 61, attachment portion 80, etc. [Explanation of symbols]
