Summary of the Invention

Problems to be Solved by the Invention

[0005] In the case of Patent Document 1 of the above background art, the connection method between the rod-shaped member and the connecting member is only to insert the rod-shaped member connecting portion of the connecting member into the hollow portion of the rod-shaped member. If there is a large clearance between the inner diameter of the hollow portion and the outer diameter of the rod-shaped member connecting portion, rattling will occur, and if there is little clearance, it will be difficult to insert. Therefore, high precision is required for the processing of the outer diameter, and the manufacturing is time-consuming. Also, the work efficiency of assembly is not good, and it is difficult to connect securely without rattling. Similarly, in the case of Patent Document 2, the connection method between the pipe and the connecting member is only to insert the end portion of the pipe into the hollow cylindrical portion of the connecting member. High precision is required for the processing of the outer diameter, and the work efficiency of assembly is not good, and it is difficult to connect securely without rattling. Since the hollow cylindrical portion is screwed and attached to the main body portion, the assembly is troublesome.

Mode for Carrying Out the Invention

[0013] Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view of a partition support unit 10 according to an embodiment of the present invention. The partition support unit 10 includes a hollow pole 12 that serves as a column or a beam, a joint 14 that is inserted and attached to one end 12b or the other end 12b of the pole 12 into a hollow cylinder portion, and a spacer 16 that is fitted between the inner peripheral surface 12a of the pole 12 and the joint 14.

[0014] First, the pole 12 will be described. The pole 12 is a hollow member made of metal with a circular cross-section, for example, an aluminum extrusion profile, and has dimensions of a diameter of 22 mm and a length of 2 m.

[0015] Next, the joint 14 will be described with reference to FIGS. 1 to 5. The joint 14 is a metal block body, for example, an aluminum die-cast. The joint 14 includes a substantially hexahedral main body portion 18 having six planar portions 18a that are respectively perpendicular to the X-axis, Y-axis, and Z-axis that are orthogonal to each other, and five insertion protrusions 20 of the same shape integrally formed on five of the six planar portions 18a of the main body portion 18.

[0016] Here, one of the pair of planar portions 18a that are perpendicular to the Z-axis, i.e., the planar portion 18c, is not provided with the insertion protrusion 20. Therefore, the five insertion protrusions 20 project in pairs away from each other in the X-axis direction, in pairs away from each other in the Y-axis direction, and one projects in the Z-axis direction, with the main body portion 18 as the center. Note that the portions of the surface of the main body portion 18 other than the planar portions 18a and 18c are chamfered to form a curved surface portion 18b, which is continuous all around and is shaped like a sphere. A gentle concave portion 19 is formed in the portion surrounded by the three planar portions 18a and 18c in the curved surface portion 18b for weight reduction. A concave portion may also be provided in the planar portion 18c for weight reduction.

[0017] The insertion protrusion 20 is a short protrusion that projects in a direction perpendicular to the planar portion 18a. The cross-sectional shape that is substantially perpendicular to the protruding direction is cross-shaped, and four elongated plate-like fins 22 are provided along the protruding direction, and adjacent fins 22 are positioned substantially perpendicular to each other. A taper is provided such that the width of the insertion protrusion 20 that intersects the protruding direction, i.e., the distance between the outer surfaces 22a of the pair of fins 22 that are parallel to each other, gradually becomes narrower as it approaches the tip 20a of the insertion protrusion 20. The inclination angle α of the outer surface 22a with respect to the protruding direction is, for example, 1.5°.

[0018] Next, the spacer 16 will be described with reference to FIGS. 1 to 3, FIGS. 6 to 8. The spacer 16 is made of a synthetic resin such as a thermoplastic resin having appropriate flexibility. The spacer 16 is composed of a pair of covering members 24 having the same shape that cover half of the insertion protrusion 20 of the joint 14, and the pair of covering members 24 are connected by a hinge portion 26. The covering members 24 can be opened and closed with respect to each other about the hinge portion 26. The end portion of the covering member 24 on the side opposite to the hinge portion 26 is a semi-cylindrical base end portion 28, and the axial length of the base end portion 28 is short. A flange portion 29 that abuts against the end portion 12b of the pole 12 is provided so as to protrude outward at the end portion of the base end portion 28 in the axial direction on the side opposite to the hinge portion 26.

[0019] On the hinge portion 26 side, which is the side opposite to the flange portion 29 in the axial direction of the base end portion 28, covering plate portions 30 that extend in the axial direction of the base end portion 28 are provided near both ends that intersect the circumferential direction of the base end portion 28. The covering plate portion 30 is overlapped with the lateral side surface 22b, which is the surface direction, of the fin 22 of the insertion protrusion 20 of the joint 14, and has a width that covers the pair of fins 22 that are flush. The end portion 30a of the covering plate portion 30 on the side opposite to the base end portion 28 protrudes slightly longer than the length of the insertion protrusion 20 and forms a plane that intersects at a right angle to the protruding direction. On the side edge portions of the covering plate portion 30 that are separated from each other, outer surface covering portions 32 that are bent in an L-shape so as to cover a range slightly narrower than half of the outer surface 22a that intersects the lateral side surface 22b of the pair of fins 22 are provided. Since the outer surface covering portion 32 is slightly narrower than half of the outer surface 22a, a gap 33 is formed between the outer surface covering portions 32 when the pair of covering members 24 are attached to cover the insertion protrusion 20 of the joint 14.

[0020] A through hole 34 is formed in the center of the covering plate portion 30, and a fin 22 that protrudes at a right angle between the pair of fins 22 that are flush is formed. A tongue piece 36 is provided outside the through hole 34 at a distance from the through hole 34 and facing the through hole 34. The tongue piece 36 is in the shape of a thin plate that is long in one direction. One end in the longitudinal direction is connected to the base end portion 28, and the opposite tip end portion 36a extends toward the hinge portion 26 side, which is the direction away from the base end portion 28, and becomes a free end.

[0021] On a pair of side edges of the tongue piece 36 along the protruding direction, there are provided outer surface covering portions 38 that are bent in an L shape so as to cover the lateral side surfaces 22b of the fins 22. The outer surface covering portions 38 are wide at the portion near the base end portion 28 and are continuous with the covering plate portion 30. The portion near the tip end portion 36a is thin and is separated from the covering plate portion 30, and the tip end portion 36a swings freely. The thickness of the tongue piece 36 along the insertion direction of the through hole 34 is provided with a taper that becomes thicker as it approaches the tip end portion 36a. The inclination angle β of the taper of the thickness of the inner side surface 36c on the side of the through hole 34 of the tongue piece 36 and the outer side surface 36b on the side opposite to the inner side surface 36c is slightly larger than the inclination angle α of the taper of the fin 22, for example, 1.6°. On the hinge portion 26 side, which is opposite to the flange portion 29 of the base end portion 28, a fan-shaped closing surface 31 is formed between the covering plate portion 30 and the outer surface covering portion 38.

[0022] A hinge portion 26 is integrally provided at the end portion 30a of the covering plate portion 30. The hinge portion 26 is a thin and small strip, and the surface of the strip is parallel to the surface direction of the covering plate portion 30. The pair of covering members 24 connected by the hinge portion 26 open and close in a direction intersecting the surface direction of the covering plate portion 30. A plurality of linear protrusions 40 are formed on the inner side surfaces of the covering plate portion 30, the tongue piece 36, and the outer surface covering portion 38 along the direction protruding from the base end portion 28.

[0023] Next, a method for assembling this partition support unit 10 will be described. First, as shown in FIG. 2, a spacer 16 is inserted into the end portion 12b of the pole 12. When the hinge portion 26 side of the spacer 16 is inserted deeper, the flange portion 29 abuts against the end portion of the pole 12, and further insertion becomes impossible, and it is installed at a predetermined position. When inserting the spacer 16, by eliminating the gap 33 between the pair of covering members 24 or shifting the outer surface covering portions 32 to reduce the diameter, it can be smoothly inserted inside the pole 12. When the flange portion 29 abuts against the end portion 12b of the pole 12, the overlap of the outer surface covering portions 32 disappears, and a continuous cylindrical shape with a gap 33 is formed.

[0024] Then, as shown in FIG. 3, one insertion protrusion 20 of the joint 14 is inserted into the spacer 16 installed on the pole 12. At this time, a pair of fins 22 that are flush with each other of the insertion protrusion 20 are overlapped on the inner side of the cover plate portion 30, and the fin 22 that stands upright at a right angle and is located between the pair of fins 22 is inserted in a direction that overlaps the inner side of the tongue piece 36. There is a closed surface 31 between the cover plate portion 30 and the outer surface covering portion 38, and since the space through which the fin 22 can pass is cross-shaped, the fin 22 of the insertion protrusion 20 is guided and easily positioned so that the joint 14 does not shift. Then, the tongue piece 36 of the spacer 16 is elastically deformed and expanded by being pressed against the outer surface 22a of the fin 22, and is pressed against the inner peripheral surface 12a of the pole 12. Since the inclination angle α of the taper of the fin 22 is 1.5° and the inclination angle β of the taper of the tongue piece 36 is 1.6°, the pressure increases as the fin 22 is inserted deeper. From this, by inserting with a relatively weak force and gradually applying force to push, strong attachment strength can be obtained, and the pole 12 and the joint 14 are connected with sufficient attachment strength. The flat surface portion 18a of the main body portion 18 of the joint 14 abuts against the outer surface of the flange portion 29 of the spacer 16 and cannot be inserted any further, and is positioned, completing the connection.

[0025] Attach the pole 12 with the spacer 16 installed to the insertion protrusions 20 of the joint 14 other than the insertion protrusion 20 inserted into the pole 12. Since the insertion protrusions 20 are positioned perpendicular to each other, the poles 12 can be connected perpendicular to each other. By repeating this, assemble the columns and beams using the poles 12 to form the partition support unit 10 shown in FIG. 9. Hang partition materials 41 made of cloth or cardboard on the beams and the like of the partition support unit 10 to form a partition 44 that surrounds the space 42 where people can enter. For example, in the case of a rectangular cloth where one width is equal to the length of the pole 12 and the other width is half the length of the pole 12, attach two sheets vertically with the longitudinal direction of the partition material 41 perpendicular to the pole 12 serving as the beam at the upper end. Thus, it is also possible to create an entrance by rolling up or bundling one partition material 41 horizontally. To provide two consecutive spaces 42 vertically and horizontally, 66 poles 12, 18 joints 14, and 90 spacers 16 are required, and these can be made into a set of products.

[0026] The partition support unit 10 of this embodiment can be easily manufactured, can be reliably assembled without rattling with simple operations, can be assembled with weak force, and can be easily set up by anyone without using tools or the like. In a shelter or event space, it can be set up in a short time to create the space 42 for taking breaks and performing various operations. Also, since the spacer 16 is provided with a pair of covering members 24 connected by a hinge portion 26, it is easy to insert into the end portion 12b of the pole 12 by squeezing the gap 33 between the covering members 24 or shifting the outer surface covering portions 32 to reduce the diameter. Since the flange portion 29 abuts against the end portion 12b of the pole 12 and is positioned without being inserted further, the positioning is easy to understand and the workability is good.

[0027] In particular, the outer surface 22a of the fin 22 of the joint 14 has a taper inclination angle α of 1.5°, and the taper inclination angle β of the inner surface 36c of the tongue piece 36 of the spacer 16 is 1.6°. Therefore, as the joint 14 is inserted deeper into the spacer 16, the tongue piece 36 can be pushed and expanded to press against the hollow inner peripheral surface 12a of the pole 12 with a strong force. For this reason, it can be inserted with a weak force and has good operability. By finally applying force and pushing, strong attachment strength can be obtained, and loosening and rattling can be prevented.

[0028] In addition, on the inner surfaces of the tongue piece 36 of the spacer 16, the outer surface covering portion 38, and the covering plate portion 30, protrusions 40 are provided in the protruding direction. Therefore, the frictional resistance when inserting the insertion protrusion 20 of the joint 14 is reduced, and it is easy to insert. Inside the base end portion 28 of the spacer 16, a closed surface 31 through which the fin 22 cannot pass is provided, and the space through which the fin 22 can pass is cross-shaped. Therefore, the fin 22 of the insertion protrusion 20 is guided and easily positioned, so the insertion operation of the joint 14 is easy. The pole 12 and the joint 14 are made of aluminum, are lightweight, recyclable, and have a low environmental load. Also, they are compact before assembly and do not occupy storage space.

[0029] Note that the partition strut unit of this invention is not limited to the above-described embodiment. The shape, material, and dimensions of each member can be freely changed.
