Summary of the Invention

Problems to be Solved by the Invention

[0004] In the attachment device described in Patent Document 1, since the connection portion provided on the bottom surface of the box is inserted into the insertion port of the fixed base, it is difficult to align the connection portion and the insertion port, and the attachment work is not easy. Further, in the attachment device of Patent Document 2, since it is necessary to perform an operation of winding the band piece around the object to be attached, the attachment work and the removal work are not easy.

[0005] The present invention has been made to solve the above problems, and its main object is to provide an attachment device that facilitates attachment and detachment work.

Means for Solving the Problem

[0006] The first configuration is a mounting device, which includes a first mounting portion provided on one of a mounting object and a mounted object, and a second mounting portion provided on the other of the mounting object and the mounted object, where the first mounting portion can be mounted. The first mounting portion includes a plate-shaped mounting mechanism having a thickness in a first direction. The second mounting portion includes a mounting region where the first mounting portion can be mounted when the mounting mechanism is disposed, a separation region where the first mounting portion can be removed from one side in the first direction when the mounting mechanism is disposed, a connecting path that bends and / or curves to connect between the mounting region and the separation region, and the mounting mechanism can reciprocate. The mounting region and the connecting path are in contact with one side in the first direction of the mounting mechanism, the separation region allows the mounting mechanism to pass through toward one side in the first direction, and the side of the separation region opposite to the side where the connecting path is connected is capable of contacting the outer edge of the mounting mechanism.

[0007] In the first configuration, when the mounting mechanism enters the separation region and is removed, the side opposite to the side where the connecting path of the mounting mechanism and the separation region is connected contacts, so that it can be sensed that the mounting mechanism has reached the separation region, and the movement of the mounting mechanism is suppressed. Therefore, an unexpected detachment of the mounting mechanism that has reached the separation region can be suppressed. In addition, since the connecting path connecting the mounting region and the separation region is curved and / or bent, even when an external force is applied to the first mounting portion and / or the second mounting portion, further movement is suppressed at the curved and / or bent portion. Therefore, a situation where the mounting mechanism enters the separation region due to an external force can also be suppressed.

[0008] The second configuration, in addition to the first configuration, has a locking portion formed at the connection portion between the separation region and the communication path, where the mounting mechanism can enter the other side in the first direction and contacts the one side in the first direction of the entered mounting mechanism.

[0009] In the second configuration, in order to move the attachment mechanism that has entered the separation region to the connection path, the locking portion abuts against one side of the attachment mechanism to suppress detachment in the detachment direction, so that detachment of the attachment mechanism disposed in the separation region can be preferably suppressed.

[0010] In addition to the first configuration, in the third configuration, the separation region is provided so as to be recessed from the periphery of the separation region.

[0011] In the third configuration, the attachment mechanism can be disposed in the separation region by sliding the attachment mechanism while bringing it into contact with the periphery of the separation region, so that the attachment of the first attachment portion to the second attachment portion can be easily performed.

[0012] In addition to any one of the first to third configurations, in the fourth configuration, the second attachment portion includes a plurality of the separation regions, and the entry directions from the attachment region to the separation regions are different.

[0013] In the fourth configuration, when moving the attachment mechanism between the attachment region and the separation region, a separation region with an easy movement operation can be selected.

[0014] In addition to any one of the first to third configurations, in the fifth configuration, the attachment region can suppress rotation of the attachment mechanism disposed therein.

[0015] In the fifth configuration, when the attachment mechanism is disposed in the attachment region, the relative posture between the first attachment portion and the second attachment portion can be maintained.

[0016] In addition to the fifth configuration, in the sixth configuration, the attachment target can accommodate an object to be accommodated from an opening to the inside, and the attachment target can be attached to the object to be attached with the opening facing upward.

[0017] In the sixth configuration, a small container or the like with the opening facing upward can be attached to a moving body, a structure, or the like.

[0018] In the seventh configuration, in addition to the fifth configuration, the separation region allows the mounting mechanism to pass through toward one side in the first direction regardless of the relative posture between the first mounting portion and the second mounting portion.

[0019] In the seventh configuration, when attaching the first mounting portion to the second mounting portion and when detaching the first mounting portion from the second mounting portion, the relative posture between the first mounting portion and the second mounting portion can be set to a posture that facilitates attachment / detachment.

[0020] In the eighth configuration, in addition to any of the first to third configurations, the second mounting portion includes a plurality of mounting regions, and the entry directions from the separation region to the mounting regions are different.

[0021] In the eighth configuration, when moving the mounting mechanism between the mounting region and the separation region, a mounting region that allows for easy movement operations can be selected.

[0022] In the ninth configuration, in addition to any of the first to third configurations, the object to be mounted is a wheelchair, the first mounting portion is mounted such that one side in the first direction is orthogonal to the longitudinal portion of the frame of the wheelchair and the first direction is the extending direction of the longitudinal portion, the first mounting portion includes a shaft portion extending in the first direction, and the mounting mechanism is provided at the tip of the other side of the shaft portion in the first direction.

[0023] In the ninth configuration, since the object to be mounted can be attached to the outside of the frame of the wheelchair and can be horizontally moved along the frame, the object to be mounted can be arranged at a suitable position for the user of the wheelchair.

[0024] The tenth configuration is an attachment structure for attaching and detaching an attachment target to / from an object to be attached, comprising a first attachment part provided on one of the attachment target and the object to be attached, and a second attachment part provided on the other of the attachment target and the object to be attached, to which the first attachment part can be attached. The first attachment part comprises a plate-like attachment mechanism having a thickness in a first direction. The second attachment part comprises an attachment area where the first attachment part can be attached by arranging the attachment mechanism, a separation area where the first attachment part can be detached from one side in the first direction by arranging the attachment mechanism, and a connecting path that bends and / or curves to connect between the attachment area and the separation area and allows the attachment mechanism to reciprocate. The attachment area and the connecting path abut on one side in the first direction of the attachment mechanism. The separation area allows the attachment mechanism to pass through toward one side in the first direction. The side of the separation area opposite to the side where the connecting path is connected can abut on the outer edge of the attachment mechanism.

[0025] In the tenth configuration, an attachment structure conforming to the first configuration can be provided.

Embodiments for Carrying out the Invention

[0027] <Embodiment> As shown in FIG. 1, the mounting device according to the present embodiment is used when attaching a small storage box 10, which is an object to be mounted, to an object to be mounted such as an arm support of a wheelchair or a structure. A first mounting portion 20 is provided on the object to be mounted side, and a second mounting portion 30 is provided on the object to be mounted side. The mounting device is constituted by the first mounting portion 20 and the second mounting portion 30. In the following description, the side to which the small storage box 10 is attached to the wheelchair is defined as the back side, and the vertical direction when attached to the wheelchair is defined as the up-down direction.

[0028] As shown in FIG. 1, the small storage box 10 is a bottomed cylindrical box body having an opening upward, and small items, which are objects to be stored, can be stored from the opening into the interior. The small storage box 10 is constituted by a plate-shaped front wall portion 11 that constitutes the front when attached to the object to be mounted, a plate-shaped right side wall portion 12 that constitutes the right side surface, a plate-shaped left side wall portion 13 that constitutes the left side surface, a back wall portion 14 that constitutes the back, and a plate-shaped bottom portion that constitutes the bottom surface.

[0029] The first attachment portion 20 will be described with reference to FIGS. 2-4. The first attachment portion 20 includes a plate-like attachment mechanism 21 having a thickness in the front-rear direction, a spherical base portion 22, and a cylindrical shaft portion 23 connecting the disc portion 21 and the base portion 22. The attachment mechanism 21 has an outer shape defined by a pair of parallel sides of equal length and a pair of arc-shaped sides connecting the respective ends of those sides. The pair of arc-shaped sides share a center, and the radius and central angle are equal. That is, the pair of arc-shaped sides constitute a part of an arc of a virtual circle that shares the arc-shaped sides and has an equal radius, and the entire attachment mechanism 21 has a shape that fits inside the virtual circle. The diameter of the base portion 22 is larger than the arc of the attachment mechanism 21, the distance between the pair of parallel sides of the attachment mechanism 21 is larger than the diameter of the shaft portion 23, and the centers of the attachment mechanism 21 and the base portion 22 are located on the extension line of the central axis of the shaft portion 23.

[0030] The base portion 22 is provided with an attachment hole 24 which is a cylindrical hole penetrating in the left-right direction, and the extending direction of the central axis of the shaft portion 23 is orthogonal to the extending direction of the central axis of the attachment hole 24. A long portion such as a frame of an arm support of a wheelchair or a rod-shaped portion of a structure is inserted into the attachment hole 24 provided in the base portion 22 and fixed thereto for attachment. At this time, since the extending direction of the long portion attached to the attachment hole 24 coincides with the extending direction of the central axis of the attachment hole 24, it is orthogonal to the extending direction of the central axis of the shaft portion 23. Therefore, it is possible to provide the small container 10, which is the object to be attached, outside the frame of the wheelchair and to move it horizontally along the frame.

[0031] On the back surface of the back wall portion 14 of the small item container 10, a second attachment portion 30 to which the first attachment portion 20 can be attached is provided. This second attachment portion 30 will be described with reference to FIGS. 5 and 6. The second attachment portion 30 includes, on the upper end side, a fixing portion 31 having a substantially semi-circular ring plate shape with the center opening in the back direction. The inner diameter of the fixing portion 31 is substantially equal to the outer shape of the shaft portion 23 of the first attachment portion 20. The shape of the upper end side of the fixing portion 31 is substantially arc-shaped, and the length from the center to the upper end is slightly larger than the diameter of the attachment mechanism 21. Also, the left and right ends of the fixing portion 31 are substantially linear and extend in the vertical direction, and the width from the center of the fixing portion 31 to the left and right ends is substantially equal to the width from the center of the attachment mechanism 21 to a pair of parallel sides. The front surface of this fixing portion 31 is a plane extending in the vertical and horizontal directions, and the distance from the back surface of the back wall portion 14 of the small item container 10 is substantially equal to the front-to-back width of the attachment mechanism 21. Also, the thickness of the fixing portion 31 is substantially equal to the distance between the attachment mechanism 21 and the base portion 22, that is, the length of the shaft portion 23.

[0032] On each of the lower ends of the fixing portion 31, a substantially rectangular plate-shaped right connecting portion 32 and left connecting portion 33 extending in the vertical direction are provided. The distance between the opposing sides of these connecting portions 32 and 33 is substantially equal to the outer shape of the shaft portion 23, and the width of the sides of the connecting portions 32 and 33 opposite to the opposing sides is substantially equal to the width between a pair of parallel sides of the attachment mechanism 21. The front and back surfaces of these connecting portions 32 and 33 are flush with the front and back surfaces of the fixing portion 31.

[0033] At the lower end of the right connecting portion 32, a semi-circular plate-shaped right locking portion 34 bulging downward is provided. On the other hand, at the lower end of the left connecting portion 33, a left locking portion 35 bulging downward is provided. These right locking portion 34 and left locking portion 35 have symmetrical shapes. At the lower end sides of the locking portions 34 and 35, a substantially rectangular plate-shaped lower end connecting portion 36 extending horizontally in the left and right direction is provided at intervals. The distance between the upper end edge of this lower end connecting portion 36 and the apex of the lower ends of the locking portions 34 and 35 is substantially equal to the outer diameter of the shaft portion 23 of the first attachment portion 20. Also, the right locking portion 34, left locking portion 35, and lower end connecting portion 36 are flush with the front and back surfaces of the fixing portion 31 and the like.

[0034] At the right end of the right locking portion 34 and the right end of the lower connecting portion 36, an annular plate-shaped right separating portion 37 with an open left end is provided so as to connect those ends. The inner diameter of this right separating portion 37 is slightly larger than the outer diameter of the mounting mechanism 21. On the other hand, at the left end of the left locking portion 35 and the left end of the lower connecting portion 36, a left separating portion 38 which is annular plate-shaped with an open right end and is symmetric with the right separating portion 37 in left-right direction is provided so as to connect those ends. Also for these left separating portion 37 and right separating portion 38, they are flush with the front and back surfaces of the fixing portion 31 etc.

[0035] The entire circumference of the outer edges of the fixing portion 31, the right connecting portion 32, the left connecting portion 33, the right locking portion 34, the left locking portion 35, the right edge and the upper edge of the right separating portion 37, and the left edge and the upper edge of the left separating portion 38 described above are connected to the back wall portion 14 of the small item container 10 by a continuously erected outer peripheral wall 39 facing the front with a uniform height. Also, no outer peripheral wall 39 is formed on the lower end side of the second mounting portion 30 and it is open. That is, it can be said that the shape of the outer peripheral wall 39 is a convex character shape with an open lower end in a front view.

[0036] The region where a part of the back is covered by the fixing portion 31, the front is blocked by the back wall portion 14, and the upper edge and the left and right edges are constituted by the outer peripheral wall 39 is called the mounting region 41. The region where a part of the back is covered by the right connecting portion 32, the left connecting portion 33, the right locking portion 34, the left locking portion 35 and the lower connecting portion 36, the front is blocked by the back wall portion 14, the upper end is connected to the mounting region 41, and the left and right edges and the edges extending from the lower ends of the left and right edges to the left and right respectively are constituted by the outer peripheral wall 39 is called the connecting path 42. Regarding this connecting path 42, since it extends vertically downward and bends at a right angle from the lower end side toward the left and right respectively, it can also be said that it is an inverted T-shaped region. Also, the region where a part of the back is covered by the right separating portion 37, the front is blocked by the back wall portion 14, and the upper edge and the right edge are constituted by the outer peripheral wall 39 is called the right separating region 47, and the region where a part of the back is covered by the left separating portion 38, the front is blocked by the back wall portion 14, and the upper edge and the left edge are constituted by the outer peripheral wall 39 is called the left separating region 48.

[0037] A method of attaching the first attachment part 20 to the second attachment part 30 will be described with reference to FIGS. 7 to 14. In the following description, an example in which the attachment mechanism 21 enters from the left separation region 48 will be described. However, since the case of entering from the right separation region 47 is the same, the description of the case of entering from the right separation region 47 will be omitted.

[0038] First, the front surface of the attachment mechanism 21 of the first attachment part 20 is brought into contact with and slid along the rear surface of the second attachment part 30. At this time, although the attachment region 41 and the connection path 42 have a width through which the shaft portion 22 can pass, the attachment mechanism 21 cannot pass through. Therefore, the attachment mechanism 21 cannot enter the attachment region 41 and the connection path 42 from the rear surface. When the attachment mechanism 21 is slid to reach the rear surface of the left separation region 48 and the first attachment part 20 and the second attachment part 30 are brought close to each other in the facing direction, as shown in FIGS. 7 and 8, the attachment mechanism 21 enters the left separation region 48.

[0039] The first attachment part 20 and the second attachment part 30 are relatively moved so that the attachment mechanism 21 that has entered the left separation region 48 moves toward the left, and the attachment mechanism 21 is made to enter the connection path 42. Then, as shown in FIGS. 9 and 10, the front surface of the left locking part 35 approaches or contacts the rear surface of the upper end side of the attachment mechanism 21, and the front surface of the lower end connection part 36 approaches or contacts the rear surface of the lower end side of the attachment mechanism 21. That is, the detachment of the attachment mechanism 21 to the rear surface side is suppressed by the left locking part 35 and the lower end connection part 36.

[0040] As shown in FIGS. 11 and 12, when the mounting mechanism 21 reaches the center in the left - right direction of the connecting path 42, the first mounting portion 20 and the second mounting portion 30 are relatively moved so as to raise the mounting mechanism 21 upward. At this time, since the distance between the right - end of the right - side connecting portion 32 and the left - end of the left - side connecting portion 33 is substantially equal to the width between a pair of parallel sides of the mounting mechanism 21, the relative posture of the first mounting portion 20 and the second mounting portion 30 is adjusted so that the upper and lower ends of the arc - shaped side of the mounting mechanism 21 face the vertical direction. When the mounting mechanism 21 is raised, the left and right of the shaft portion 23 are sandwiched between the right - side connecting portion 32 and the left - side connecting portion 33, the back surface of the mounting mechanism 21 approaches or abuts against the front surfaces of the right - side connecting portion 32 and the left - side connecting portion 33, and a pair of parallel sides of the mounting mechanism 21 approach or abut against the left and right inner surfaces of the outer peripheral wall 39.

[0041] If the raising of the mounting mechanism 21 is continued, as shown in FIGS. 13 and 14, the mounting mechanism 21 reaches the mounting area 41. At this time, the shaft portion 23 abuts against the inner peripheral edge of the fixing portion 31, the arc - shaped side on the upper - end side of the mounting mechanism 21 abuts against or approaches the lower surface of the outer peripheral wall 39, a pair of parallel sides approach or abut against the left and right inner surfaces of the outer peripheral wall 39, and the back surface of the mounting mechanism 21 approaches or abuts against the front surface of the fixing portion 31. Therefore, in the mounting area 41, the upward movement and the separation from the back - side of the mounting mechanism 21 are suppressed by the fixing portion 31, and the rotation within the mounting area 41 is suppressed by the left and right side surfaces of the outer peripheral wall 39. That is, when the mounting mechanism 21 is positioned within the mounting area 41, the relative movement and the change in the relative posture between the first mounting portion 20 and the second mounting portion 30 are suppressed. In the state where the first mounting portion 20 is attached to the second mounting portion 30 in this way, it is attached to the object to be mounted with the opening of the small - item case 10 provided with the second mounting portion 30 facing upward.

[0042] Next, the case of removing the first attachment part 20 from the second attachment part 30 will be described with reference to FIGS. 7-14 again. When removing the first attachment part 20, the attachment mechanism 21 located within the attachment region 41 is moved to the right separation region 47 or the left separation region 48. Here, the case of moving the attachment mechanism 21 to the left separation region 48 will be described. However, since the case of moving it to the right separation region 47 is the same, the description of the case of moving it to the right separation region 47 will be omitted.

[0043] First, by relatively moving the first attachment part 20 and the second attachment part 30 in the vertical direction, the attachment mechanism 21 is moved downward within the connection path 42. As shown in FIGS. 11 and 12, when the attachment mechanism 21 reaches the lower end of the connection path 42, the shaft part 23 abuts against the upper edge of the lower end connection part 36, and the back surface of the attachment mechanism 21 approaches or abuts against the front surfaces of the right locking part 34, the left locking part 35, and the lower end connection part 36.

[0044] After the attachment mechanism 21 reaches the lower end of the connection path 42, by relatively moving the first attachment part 20 and the second attachment part 30 in the horizontal direction, the attachment mechanism 21 is moved to the left separation region 48. Since the inner diameter of the left separation part 38 is larger than the outer diameter of the attachment mechanism 21 as shown in FIGS. 7 and 8, if the first attachment part 20 and the second attachment part 30 are relatively moved so as to be separated in the front-rear direction, the attachment mechanism 21 located within the left separation region 48 will disengage rearward from the back surface of the left separation region 48. Thus, the removal of the first attachment part 20 from the second attachment part 30 is completed.

[0045] Incidentally, when moving the attachment mechanism 21 into the left separation region 48, if the momentum for moving it in the left direction is large, as shown in FIGS. 15 and 16, the center of the attachment mechanism 21 moves to the right of the center of the left separation region 48, and the outer peripheral surface of the attachment mechanism 21 comes into contact with the inner peripheral surface of the outer peripheral wall 39 of the left separation region 48. At this time, the back surface of the attachment mechanism 21 comes close to or contacts the front surface of the left separation part 38, and the detachment of the attachment mechanism 21 to the back surface side is suppressed. That is, when moving the attachment mechanism 21 to the left, the situation of accidentally detaching from the left separation region 48 due to excessive momentum is suppressed. When the attachment mechanism 21 reaches the left end of the left separation region 48, if the attachment mechanism 21 is moved slightly to the right so that the attachment mechanism 21 and the center of the left separation region 48 are substantially aligned, the first attachment part 20 can be removed from the second attachment part 30.

[0046] With the above configuration, the attachment device composed of the first attachment part 20 and the second attachment part 30 according to the present embodiment has the following effects.

[0047] · When the attachment mechanism 21 enters the separation regions 47 and 48 and is removed, the side opposite to the side where the connection path 42 between the attachment mechanism 21 and the separation regions 47 and 48 is connected comes into contact, so that it is possible to sense that the attachment mechanism 21 has reached the separation regions 47 and 48, and since the movement of the attachment mechanism 21 is suppressed, it is possible to suppress the accidental detachment of the attachment mechanism 21 that has reached the separation regions 47 and 48.

[0048] · Since the connection path 42 connecting the attachment region 41 and the separation regions 47 and 48 is bent, even when an external force is applied to the first attachment part 20 and / or the second attachment part 30, further movement is suppressed at the bent portion, so that it is possible to suppress the situation where the attachment mechanism 21 enters the separation regions 47 and 48 due to the external force.

[0049] · When moving the attachment mechanism 21 that has entered the separation regions 47 and 48 to the connection path 42, the locking portions 34 and 35 contact one side of the back surface of the attachment mechanism 21 to suppress detachment in the detachment direction, so that it is possible to preferably suppress the detachment of the attachment mechanism 21 disposed in the separation regions 47 and 48.

[0050] ·By sliding the attachment mechanism 21 while bringing it into contact with the peripheries of the separation regions 47 and 48, the attachment mechanism 21 can be disposed within the separation regions 47 and 48, so that the attachment of the first attachment portion 20 to the second attachment portion 30 can be easily performed.

[0051] ·Since the connection path 42 branches in the middle and leads to two separation regions 47 and 48 in different directions, it is possible to select the separation regions 47 and 48 where the movement operation is easy for moving the attachment mechanism 21 between the attachment region 41 and the separation regions 47 and 48.

[0052] ·Since a pair of parallel sides constituting the outer shape of the attachment mechanism 21 are closely attached or abutted and clamped to the inner peripheral surface of the outer peripheral wall 39 extending parallel in the vertical direction, when the attachment mechanism 21 is disposed within the attachment region 41, the relative posture between the first attachment portion 20 and the second attachment portion 30 can be maintained.

[0053] ·Since the inner diameters of the separation portions 37 and 38 are larger than the outer diameter of the attachment mechanism 21, when attaching the first attachment portion 20 to the second attachment portion 30 and when detaching the first attachment portion 20 from the second attachment portion 30, the relative posture between the first attachment portion 20 and the second attachment portion 30 can be set to a posture where attachment / detachment is easy.

[0054] ·Small articles holders 10 and the like, which are objects to be attached, can be attached to the outside of the frame of the wheelchair and can be horizontally moved along the frame, so that the object to be attached can be disposed at a position suitable for the user of the wheelchair. <Modification Example>

[0055] ·In the embodiment, the attachment region 41 and the separation regions 47 and 48 are connected by an inverted T-shaped connection path 42 that bends at right angles to the left and right from the tip extending downward, but the shape of the connection path 42 is not limited to this, and other shapes such as an inverted Y-shaped may be used, and it is not limited to being bent and may be curved. Also, one connection path may be curved and the other connection path may be bent.

[0056] · In the embodiment, the attachment region 41 is connected by two separation regions 47, 48 and a connecting path 42. However, the number of separation regions may be one. In that case, the connecting path may be bent or curved.

[0057] · In the embodiment, the attachment region 41 is connected by two separation regions 47, 48 and a connecting path 42. However, the number of separation regions may be three or more. In that case, the connecting path may be bent or curved.

[0058] · In the embodiment, the connecting path 42 that connects the attachment region 41 and the two separation regions 47, 48 branches left and right in the middle. However, the attachment region 41 and the separation regions 47, 48 may be connected by different connecting paths respectively. The same applies when the number of separation regions is three or more.

[0059] · When connecting one attachment region 41 and one separation region by a connecting path, the connecting path may be connected by a plurality of connecting paths with different bending directions and / or curved directions. In this case, even if there is one attachment region and one separation region respectively, a connecting path that is easy to attach / detach can be selected.

[0060] · In the embodiment, one attachment region 41 and two separation regions 47, 48 are connected by a connecting path 42. However, a plurality of attachment regions and one separation region may be connected by a connecting path. In this case, similar to each of the above-described modified examples, the shape of the connecting path may be various bent shapes or curved shapes, the connecting path may branch in the middle, or may be connected by a plurality of different connecting paths.

[0061] · In the embodiment, one mounting region 41 and two separation regions are connected by a connecting path 42. However, it may be the case where a plurality of mounting regions and a plurality of separation regions are connected by a connecting path. Also in the connection method in this case, structures according with the various modifications described above can be applied.

[0062] · In the embodiment, regarding the shape of the mounting mechanism 21, the outer shape is defined by a pair of parallel sides and a pair of arcs connecting both ends of the sides. However, it may be circular, or may be other circular shapes such as an oval or an ellipse, or may be polygonal.
