However, when using the connecting members disclosed in Patent Documents 1 and 2, assembly may be difficult if the position of the hole of each box is not formed at an accurate position due to manufacturing errors or the like. is there. For this reason, the required manufacturing dimensional accuracy is increased, the yield of the product is lowered, and there is a possibility that the cost is increased.
Here, if the diameter of the hole is made larger than the outer diameter of the connecting member, the box members can be connected even if the hole is not formed at the correct position, but the connecting member moves within the hole. As a result, the assembled product may become loose and the usability may be reduced.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a connecting member that can reduce the manufacturing cost while improving usability, and an assembly housing including the connecting member. To do.

In order to solve the above problems, the present invention employs the following means.
That is, the connecting member according to the present invention is provided between the hole portions formed in the outer wall surface of each box body so as to face each other when the outer wall surfaces of the pair of box bodies face each other. A connecting member that connects the box bodies in a state of abutting each other, and is provided at a connecting portion having a rod shape along an axis, and at both end portions of the connecting portion in the axial direction, and in each of the hole portions. A pair of heads that are inserted and supported, and whose outer diameter in the radial direction of the axis is larger than that of the connection part, and the head is a part of a sphere whose center is located on the axis; and A transition portion that is formed between a part of a sphere and the connection portion and has a surface that smoothly continues from the surface of the sphere to the surface of the connection portion, and the diameter of the outer peripheral surface of the head region including the maximum outer dimension of the direction, the ball Of the cross section perpendicular to the axis of, characterized in that it becomes equator curved surface extending in a strip shape including an outer periphery of the largest circle diameter becomes maximum.

According to such a connecting member, the region including the maximum outer dimension of the outer peripheral surface of the head of the connecting member has a curved surface shape, and further, this head has an outer dimension in the radial direction of the axis rather than the connecting portion. Is getting bigger. For this reason, the head is inserted into the hole of the box, and the curved surface region of the outer peripheral surface is supported inside the hole, so that the head can rotate in three dimensions. . Therefore, if the positions of the holes formed in each box are not accurate, and there is a misalignment between the openings of the opposing holes when the outer wall surfaces of the pair of boxes are abutted together Even so, the connecting member can be rotated about the head as a fulcrum without the connecting member translating in the hole. Therefore, it is possible to absorb the positional deviation between the holes while firmly connecting the boxes and suppressing backlash between the connected boxes. As a result, it is not necessary to discard the box body in which the positional deviation is generated in the hole, and it is possible to suppress the yield reduction of the box body.
In addition, the curved surface of the equator allows the connecting member to rotate more smoothly with the head as a fulcrum, and even if there is a positional deviation between the openings of the opposing holes, a pair of boxes Connection between bodies becomes possible.

  Further, the connecting member according to the present invention is provided across the hole portions formed in the outer wall surface of each box body so as to face each other when the outer wall surfaces of the pair of box bodies face each other. A connecting member that connects the box bodies in a state of abutting each other, and is provided at a connecting portion having a rod shape along an axis, and at both end portions of the connecting portion in the axial direction, and in each of the hole portions. A pair of heads that are inserted and supported, and whose outer dimensions in the radial direction of the axis are larger than those of the connecting portions, and the heads are part of a sphere whose center is located on the axes, It has only the part which forms the equatorial part curved surface extended in strip | belt shape including the outer periphery of the largest circle where a diameter becomes the largest among the cross sections orthogonal to the said axis line in a spherical body.

  Furthermore, the head may further include a hemispherical portion located on a side farther from the connection portion in the axial direction than the maximum circle, out of spheres whose centers are located on the axial line.

  When the head has such a hemispherical portion, the outer peripheral surface of the head becomes a hemispherical surface on the side inserted into the hole. Accordingly, since the hemispherical surface faces the inner peripheral surface of the hole portion, the head can be smoothly inserted into the hole portion, so that the connecting member can be easily installed.

  Furthermore, the assembly and storage according to the present invention includes the above-described connecting member, and a pair of boxes formed with holes into which the pair of heads of the connecting member are inserted. .

  According to such assembling and storing, the region including the maximum outer dimension of the outer peripheral surface of the head has a curved surface shape, and includes a connecting member whose outer dimension in the radial direction of the axis is larger than that of the connecting portion. For this reason, when the outer wall surfaces of a pair of boxes are abutted with each other, the connecting member is translated in the hole even if there is a positional shift between the openings of the opposing holes. The connecting member can be rotated with the head as a fulcrum. By such a rotation operation of the connecting member, it is possible to absorb the positional deviation between the hole portions while suppressing the backlash between the connected box bodies, and it is possible to suppress the yield reduction of the box bodies.

  The hole may be formed with a rib protruding inward from the inner peripheral surface of the hole and contacting the outer peripheral surface of the head.

  Compared to the case where the outer peripheral surface of the head and the inner peripheral surface of the hole are in direct contact with each other, the contact area can be reduced when the outer peripheral surface of the head and the rib are in contact with each other. For this reason, the rib is deformed so as to be squeezed toward the inner peripheral surface of the hole by the pressing force received from the head, and the space into which the head is inserted is easily expanded. Moreover, the frictional force at the time of inserting a head into a hole part can be reduced. Therefore, it becomes easy to insert the head into the hole.

  Further, each of the pair of box bodies is formed with the hole portions on both the upper and lower outer wall surfaces, and each of the pair of box bodies can be turned upside down and brought into contact with each other. It may be connectable.

  As described above, the boxes can be connected to each other in a state in which the backlash between the boxes is suppressed, so that a decrease in the yield of the boxes can be suppressed and assembly in an inverted state is possible. For this reason, when the box has a vertically asymmetric structure, the shape of the entire assembly and storage can be changed, and the degree of freedom in use is increased.

  According to the connecting member of the present invention and the assembly and storage provided with the connecting member, the manufacturing cost is achieved while improving the usability by providing the head including the curved surface in the region including the maximum outer shape on the outer peripheral surface. Can be suppressed.

Hereinafter, the assembly storage 1 which concerns on embodiment of this invention is demonstrated.
As shown in FIG. 1, the assembly storage 1 is a state in which the lower box 3 and the upper box 4 in which the storage space S is formed inside, and the outer wall surfaces of the lower box 3 and the upper box 4 are abutted with each other. And a connecting member 20 to be connected.
In the present embodiment, for convenience of explanation, the lower box 3 and the upper box 4 are described separately, but they may be the same as described later.

  As shown in FIG. 2, the lower box 3 includes a bottom plate 10 facing the installation surface such as the ground, a pair of side plates 11 erected upward from both edges in the width direction of the lower plate, and a depth direction of the lower plate. A back plate 12 is provided so as to stand upward from the rear end edge and provided between the side plates 11. The bottom plate 10, the side plate 11, and the back plate 12 are rectangular.

Further, the lower box 3 is open on the upper side and the front side in the depth direction, and the storage space S can be accessed from the upper side and the front side. Here, the depth direction refers to a direction from the side accessing the storage space S toward the back plate 12, and hereinafter, the near side in the depth direction is referred to as a front side, and the back plate 12 side is referred to as a rear side.
The bottom plate 10, the side plate 11, and the back plate 12 are made of resin such as plastic, wood, metal, etc., and the material is not limited.

  The side plate 11 has a plate-like main body plate portion 11a, and a frame plate portion 11b provided so as to protrude outward in the width direction from each of the four end faces of the main body plate portion 11a, and this frame plate portion 11b. Is the outer wall surface of the side plate 11.

In the present embodiment, the main body plate portion 11a is formed with quadrangular through-hole portions H0 that are regularly arranged in the vertical and front-back directions so as to penetrate in the width direction.
Furthermore, in the present embodiment, the front frame plate 13 stands on the front end side of the main body plate portion 11a between the main plate portions 11a of each side plate 11 and with a height dimension smaller than that of the back plate 12 from the bottom plate 10. It is installed.

  A hole H is formed in the frame plate portion 11bA located on the upper end surface of the side plate 11 so as to be recessed from the surface of the frame plate portion 11b downward. In the present embodiment, one hole H is formed at each end in the front-rear direction of the frame plate portion 11bA.

  Here, the main body plate portion 11a is further downward from the surface facing the lower side of the frame plate portion 11bA so that each hole H is formed along the main body plate portion 11a to the midway position of the main body plate portion 11a. A cylindrical portion 11c is provided that extends and bulges outward from the main body plate portion 11a in the width direction.

  Similarly, the hole portion H is recessed from the surface of the frame plate portion 11bB upward in the frame plate portion 11bB located on the lower end surface of the side plate 11, and is formed at both ends in the front-rear direction of the frame plate portion 11bB. It is formed one by one. And so that each hole H is formed to the middle position of the main body plate portion 11a along the main body plate portion 11a, the main body plate portion 11a extends further upward from the surface facing the upper side of the frame plate portion 11bB, And the cylindrical part 11c formed so that it may swell to the width direction outer side from the main-body board part 11a is provided.

  Further, as shown in FIG. 3, these hole portions H are spaced in the circumferential direction of the inner peripheral surface so as to protrude from the inner peripheral surface of the hole portion H to the entire area in the vertical direction toward the inner side of the hole portion H. The ribs 17 are formed with a gap (four in this embodiment at equal intervals).

  The rib 17 has an end surface 17a facing the inside of the hole H. Further, at a position close to the opening of the hole H, the rib 17 is continuous with the end surface 17a and approaches the inner peripheral surface of the hole H toward the opening of the hole H. It has the inclined surface 17b formed so that protrusion amount may become small (refer FIG. 5).

As shown in FIG. 1, the upper box 4 includes a bottom plate 10 </ b> A, a pair of side plates 11 </ b> A, a back plate 12 </ b> A, and a front frame plate 13 </ b> A, similar to the lower box 3 described above. The upper box 4 has the same width and depth dimensions as the lower box 3 so that it can be placed on the upper part of the lower box 3, but the vertical direction is lower than that of the lower box 3. The dimensions are small.
Here, the upper box 4 is not limited to the case where the vertical dimension is smaller than that of the lower box 3, but the vertical dimension is larger than that of the lower box 3, that is, It may be the case where the lower box 3 and the upper box 4 are interchanged up and down, or the case where the lower box 3 and the lower box 3 have the same vertical dimension.

And in a state where the upper box 4 is placed on the upper part of the lower box 3, the frame plate part 11b of the lower box 3 and the frame plate part 11b of the upper box 4 are abutted and contacted with each other. The hole H of the box 3 and the hole H of the upper box 4 are positioned so as to face each other vertically.
Note that the term “opposite” as used herein includes a case where the position of the hole H is slightly displaced between the front and rear in the depth direction and the right and left in the width direction.

Next, the connecting member 20 will be described.
As shown in FIG. 4A and FIG. 4B, the connecting member 20 includes a connecting portion 21 having a rod shape and a pair of head portions 22 provided at both ends of the connecting portion 21. Yes.

  The connecting portion 21 extends along the axis O. Moreover, in this embodiment, although the connection part 21 has comprised the column shape centering on the axis line O, it may have comprised the prism shape, for example, and the cross-sectional shape orthogonal to the axis line O is not limited to a circle.

  The heads 22 are provided integrally with the connection parts 21 one by one at both ends of the connection part 21 in the direction of the axis O, and are inserted into the holes H of the lower box 3 and the upper box 4 one by one. Thus, the connecting member 20 is arranged between the lower box 3 and the upper box 4 with the upper box 4 placed on the lower box 3 (see FIG. 5).

  Further, the head portion 22 has a larger outer dimension in the radial direction of the axis O than the connection portion 21. Further, the maximum external dimension of the head portion 22 is such that it contacts the rib 17 in the hole H. Here, the degree of contact means not only simple contact but also storage of the head 22 formed by the end surface 17a on the inner peripheral side of the rib 17 so that the head 22 is fitted into the hole H. This includes the case where the maximum external dimension of the head 22 is larger than the external dimension of the space.

  Further, the head 22 has a part 23 of a sphere in which the center P is located on the axis O and the diameter dimension around the axis O is larger than that of the connecting portion 21. More specifically, in the head portion 22, a pole portion that is an end portion on the connection portion 21 side with respect to a portion where the diameter of the sphere is maximum is cut off in a cross section along the radial direction of the axis O. It has a shape like that. And the connection part 21 is extended from the part cut off.

  In the present embodiment, the sphere of the head 22 is a sphere having a perfect cross section, but may be a sphere having a cross section ellipse, for example. The head portion 22 includes a transition portion 24 having a surface formed so as to be smoothly continuous from the sphere surface to the surface of the connection portion 21 between the sphere portion 23 and the connection portion 21.

  In this way, the region including the maximum outer dimension of the outer peripheral surface of the head 22 includes the outer periphery of the maximum circle C having the maximum diameter among the cross sections orthogonal to the axis O in the sphere, and extends in the circumferential direction of the axis O. The equator curved surface 30 extends in a belt shape. In other words, the region including the maximum outer dimension of the outer peripheral surface has a curved surface extending uniformly in the circumferential direction of the axis O with the axis O as the center.

  Furthermore, in the present embodiment, the head 22 is arranged in the direction of the axis O rather than the maximum circle C in the sphere so that the head 22 is continuously overlapped with a portion where the equator curved surface 30 as the part 23 of the sphere is formed. It has a hemispherical portion 25 located on the side away from the connecting portion 21.

  According to such assembly housing 1, the region including the maximum outer dimension of the outer peripheral surface of the head portion 22 of the connecting member 20 is the equator portion curved surface 30 and has a curved surface shape. Further, the head portion 22 has a larger outer dimension in the radial direction of the axis O than the connection portion 21. For this reason, the head 22 is inserted into the hole H of the lower box 3 and the upper box 4 and the equator curved surface 30 is supported inside the hole H, so that the head 22 is three-dimensionally. It can be rotated.

  Specifically, as shown in FIG. 5, when there is no misalignment between the hole portions H of the lower box 3 and the upper box 4, the axis O of the connection portion 21 extends vertically. The connecting member 20 is arranged to extend. In this state, as shown in FIG. 6, when there is a displacement in the left and right (or front and back) between the hole H of the lower box 3 and the hole H of the upper box 4 due to a manufacturing error or the like. The head portion 22 is rotated in the hole H, and the axis O of the connecting portion 21 is arranged in an inclined state with respect to the vertical direction.

  Further, since the head 22 can be rotated in three dimensions, there is a positional shift between the hole H of the lower box 3 and the hole H of the upper box 4 both in the left and right and front and rear directions. Even if it occurs, the connecting member 20 can be disposed between the lower box 3 and the upper box 4 in a state where the lower box 3 and the upper box 4 are abutted.

  Therefore, even when the position difference is generated in the hole H when the frame plate portions 11b in the lower box 3 and the upper box 4 are brought into contact with each other, the connecting member 20 is rotated with the head 22 as a fulcrum. It can be operated. Further, during this rotation operation, the connecting member 20 does not translate back and forth and left and right within the hole H.

  Therefore, the lower box 3 and the upper box 4 are firmly connected to each other, and it is possible to absorb the positional deviation between the hole portions H while suppressing the rattling after the connection. As a result, it is not necessary to discard the lower box 3 and the upper box 4 that have been displaced in the hole H due to manufacturing errors or the like, and yield reduction can be suppressed.

  In addition, since the region including the maximum outer dimension of the outer peripheral surface of the head 22 is the equator curved surface 30, the head 22 rotates around the center P of the sphere, so in any direction Even in the case of rotation, the connecting member 20 can be rotated more smoothly in the hole H with the head 22 as a fulcrum.

  Furthermore, since the head portion 22 has a hemispherical portion 25, the outer peripheral surface of the head portion 22 becomes a hemispherical surface 31 on the side inserted into the hole portion H. Therefore, since the hemispherical surface 31 faces the inner peripheral surface of the hole H and the rib 17, the head 22 can be smoothly inserted into the hole H without being caught, and the connecting member 20 can be easily installed.

  A rib 17 is formed on the inner peripheral surface of the hole H. When the head portion 22 is inserted into the hole H, the end surface 17 a of the rib 17 comes into contact with the region including the maximum outer shape of the head portion 22, that is, the equator portion curved surface 30. Here, when the dimension of the head portion 22 is such a size that the head portion 22 is fitted into the hole portion H, the outer peripheral surface of the head portion 22 and the inner peripheral surface of the hole portion H are in direct contact with each other, The contact area can be reduced when the outer peripheral surface of the head 22 and the rib 17 are in contact with each other.

  For this reason, the rib 17 is deformed so as to be crushed toward the inner peripheral surface of the hole H by the pressing force received from the head portion 22, and the space into which the head portion 22 is inserted is easily expanded in diameter. Further, it is possible to reduce the frictional force when the head 22 is inserted into the hole H. Therefore, it becomes easy to insert the head 22 into the hole H.

  Further, the rib 17 is formed with an inclined surface 17 b on the opening side of the hole H. For this reason, since the head 22 can be inserted into the hole H so as to slide on the inclined surface 17b, the connecting member 20 can be more easily installed.

  According to the assembly storage 1 of the present embodiment, the head 22 is inserted into the hole H so that the lower box 3 and the upper box 4 are connected to each other when the lower box 3 and the upper box 4 are connected. It is possible to improve the usability by suppressing the rattling in the meantime and to reduce the manufacturing cost by improving the yield.

Although the embodiment of the present invention has been described in detail above, some design changes can be made without departing from the technical idea of the present invention.
For example, as shown in FIG. 7, the connecting member 20 </ b> A has only a portion including a maximum circle C in which the diameter of the sphere is maximum as a part 23 of the sphere, that is, a portion forming an equatorial curved surface 30. It may be a shape. In other words, in the sphere, both pole portions on both ends in the direction of the axis O are shaped so as to be cut off in a cross section along the radial direction of the axis O. Even in such a shape, the head 22 can be three-dimensionally rotated in the hole H, so that the backlash between the lower box 3 and the upper box 4 is suppressed and the usability is improved. In addition, the production cost can be suppressed by improving the yield.

  Further, the connecting member 20 does not have a shape having a part 23 of a sphere, but at least a region including the maximum outer dimension of the outer peripheral surface has a curved shape extending uniformly in the circumferential direction of the axis O around the axis O. It only has to be.

  Moreover, as a material of the connection member 20, resin, a metal, wood, etc. are used, and it is not specifically limited. However, in order to suppress rattling between the lower box 3 and the upper box 4 after assembly, it is preferable to use a material having as much rigidity as possible.

  Further, the rib 17 is not necessarily formed, and when the head 22 is inserted into the hole H, the outer peripheral surface of the head 22 may be in direct contact with the inner peripheral surface of the hole H.

  Here, as shown in FIG. 8, the assembly storage 1 is placed on the lower box 3 by turning the upper box 4 upside down, and the upper box 4 and the lower box 3 are connected. Good. In this case, the storage space S in the upper box 4 opens downward and forward, and defines one large space S1 together with the storage space S of the lower box 3.

  That is, since the upper box 4 has a vertically asymmetric structure, it is possible to change the shape of the entire assembly storage 1 by reversing the top and bottom, and the degree of freedom in use is increased.

  Also, a separate caster can be attached to the hole H located at the lower part of the lower box 3.

  Furthermore, in the above-described embodiment, the lower box 3 and the upper box 4 are connected to each other in the vertical direction. However, for example, by changing the formation position and quantity of the hole H appropriately, It is also possible to butt and connect.

  In the above-described embodiment, the assembly storage 1 in which the boxes (the lower box 3 and the upper box 4) whose storage spaces S open to the outside has been described. However, the connecting member 20 may be a clothing case or the like. It is also possible to use it for the connection of boxes.
