Description

Slide coupling device

The present invention relates to a slide coupling device.

Technologies related to various space construction methods have been released for the convenience of many people using the space in offices. For example, Patent Document 1 includes one or a plurality of columnar bodies extending upward from the floor and one or a plurality of horizontal beam bodies extending horizontally on the floor, and the columnar bodies and the horizontal beam bodies, the columnar bodies, and the horizontal beam bodies. A spatial structure configured by connecting the two is disclosed. Further, in Patent Document 1, the inside of a groove provided in a columnar body or a horizontal beam body and surrounded by an inner wall in a cross section and having an opening in a part thereof can be moved to any position along the groove, and the position A slide connecting device is disclosed that can be fixed to the frame. The slide coupling device includes a base member having a coupling portion for coupling to an external member, and a biasing member configured to be separable from the base member and biasing the base member to the inner wall near the opening in the groove, When the base member is pressed against the biasing member, the connecting portion can be connected to the external member through the opening. In the slide coupling device, the base member moves in the groove, so that the slide coupling device itself can move to an arbitrary position along the groove. Then, by urging the base member against the inner wall near the opening of the groove by the urging member, the slide connecting device itself can be fixed at the arbitrary position. Furthermore, by configuring the base member and the biasing member as separate members that can be separated, the slide coupling device can be smoothly moved in the groove when the two members are separated, and the biasing member is separated from the base member. In the contacted state, a biasing force is exerted on the base member by the biasing member, and the slide coupling device can be fixed. However, this fixed state is a state in which the connecting device can be moved by applying a certain force such as holding it by hand.

Japanese Patent No. 4332148

In constructing a space, further strength improvement may be required depending on the purpose of use. For example, in the above prior art, the strength can be improved by increasing the thickness of the part to which the load is applied. However, for example, a member housed in the groove such as a slide connecting member may be difficult to be removed from the groove if the thickness of the member (volume of the member) is increased. Therefore, in order to improve the strength of the member, it is also required to be easy to handle when assembling the spatial structure. On the other hand, such a requirement is not limited to a space structure, but exists in a member having a groove.

In view of the above-described problems, an object of the present invention is to provide a technology related to a slide coupling device that is slidable in a groove of a member having a groove and that is excellent in strength and easy to handle. .

In order to solve the above-described problem, the present invention increases the thickness of a base member having a connecting portion for connecting to an external member as compared with the conventional one, and is configured to be separable from the base member. As for the auxiliary member for restricting movement, the shape of the base member is designed so that the base member having a thickness larger than that of the conventional member can be accommodated and the base member can be easily taken out from the groove.

Specifically, the present invention is a slide coupling device that is slidable in a groove of a member having a groove, and the slide coupling device is surrounded by an inner wall in a cross section and has an opening in a part thereof. A base member that can be moved to any position along the groove and can be fixed to the position, and has a connecting portion for connecting to an external member, and the base member is configured to be separable. An auxiliary member made of a member, wherein the base member is placed in the groove, and a main body portion that urges an inner wall of the groove, and an arm portion that extends from an end portion of the main body portion, the opening An auxiliary member including an arm portion from which the tip portion is exposed.

In the present invention, since the base member moves in the groove, the slide coupling device itself can move to an arbitrary position along the groove. And the main-body part of the auxiliary member which consists of a flexible member is accommodated in a groove | channel, and a slide coupling apparatus itself can be temporarily fixed in this arbitrary position by urging | biasing the inner wall of a groove | channel. Temporary fixing is a state in which the connecting device can be moved by applying a certain force such as holding by hand. In addition to the temporary fixing, the fixing according to the present invention includes a state in which movement is restricted using a member such as a screw. In addition, by configuring the base member and the auxiliary member as separate members that can be separated, the slide coupling device can be moved more smoothly in the groove in a state in which both are separated. The main body and the arm are made of a flexible member. The flexible member is a thin plate-like member that bends when an external force is applied. That is, in the slide connecting member according to the present invention, the main body portion on which the base member is placed can be configured by a thin plate-like member, and the arm portion extends from the end portion of the main body portion. It can be secured sufficiently. Therefore, the base member can be made thicker than before, and the strength of the base member can be improved than before. Moreover, since the arm part is extended from the edge part of the main-body part, the movement to the longitudinal direction of the groove | channel of the base member mounted in the main-body part can be controlled. Furthermore, since the tip of the arm is exposed from the opening, the auxiliary member can be easily taken out from the groove by gripping the tip of the arm. In addition, by configuring the base member and the auxiliary member as separate members that can be separated, the base member and the auxiliary member can be separately taken into and out of the groove. Therefore, even a base member having a thickness greater than that of the conventional one can be easily put in and out of the groove. That is, the slide coupling device of the present invention can be easily attached and removed from the groove, and is easy to handle. Examples of the external member include a columnar body, a horizontal beam body, and an optional member used for a spatial structure including one or more columnar bodies extending upward from the floor and one or more horizontal beam bodies extending horizontally on the floor. .

Here, the groove may be gradually narrowed toward the back side, and the main body may be curved so as to protrude toward the back side of the groove. When the width of the groove gradually decreases toward the back side, the main body portion is curved so as to protrude to the back side of the groove according to this, so that the auxiliary member is accommodated in the groove and the slide coupling device is When temporarily fixing, the auxiliary member bends appropriately according to the shape in the groove, and the urging force is effectively exhibited. The arm portion is connected via bent portions provided at both ends of one side in the width direction of the groove among the end portions of the main body portion, and the distal end portion of the arm portion is an opening of the groove. You may make it contact | connect one wall surface of a pair of wall surface which straddles a part and forms this opening part. Thereby, the front-end | tip part of an arm part straddles the opening part of a groove | channel, and it engages with one wall surface of a pair of wall surface which forms this opening part. In other words, the tip of the arm engages with the inner wall of the wall located on the other side of the main body. Therefore, the temporarily fixed state is stably maintained.

The present invention is a slide connecting device that can slide in a groove of a member having a groove, and the slide connecting device is surrounded by an inner wall in a cross section and has an opening in the groove. It is an auxiliary member made of a flexible member that can be moved to any position along the base line and can be fixed to the position, and is configured to be separable from the base member having a connecting portion for connecting to an external member. The base member is placed in the groove, and a main body portion that urges the inner wall of the groove and an arm portion that extends from an end portion of the main body portion, and the tip portion is exposed from the opening. It can also be specified as a slide coupling device provided with an auxiliary member including an arm portion.

According to the present invention, it is possible to provide a technology relating to a slide coupling device that is slidable in a groove of a member having a groove and that is excellent in strength and easy to handle.

<Configuration>
<< Overall >>
FIG. 1 shows an overview of the entire space structure 1. The spatial structure 1 mainly includes a plurality of poles 2a to 2j (hereinafter collectively referred to as “pole 2”) and a plurality of horizontal beams 3a to 3i (hereinafter collectively “pole 2”). And a small beam 4a to 4c (hereinafter collectively referred to as “small beam 4”). The pole 2 extends vertically upward from the floor surface to support the space structure 1, and the beam 3 and the small beam 4 extend horizontally to the floor surface and connect the poles 2 or the beams 3 to each other.

Specifically, the spatial structure 1 shown in FIG. 1 has a rectangular shape, and has six poles 2a to 2f near the middle of the four corners and long sides thereof. The tops of these poles 2a to 2f are connected by seven beams 3a to 3g. Further, a pole 2g is provided so as to face the pole 2a in the front of FIG. 1, and a brace 5 is stretched between the pole 2a and the pole 2g. This pole 2g is connected in the middle of the beam 3a. A small beam 4a extending horizontally to the floor surface is connected to the bottom of the pole 2a and the pole 2g. The strength of the space structure 1 can be improved by the small beam 4a, the poles 2a and 2g, the beam 3 and the brace 5.

Furthermore, a pole 2h is provided so as to face the pole 2e. This pole 2h is connected in the middle of the beam 3b. Two small beams 4b are connected between the pole 2e and the pole 2h, and a shelf 6 is provided in a space surrounded by the small beams 4b and the poles 2e and 2h. Furthermore, two poles 2i and 2j connected in the middle of the beam 3d are provided between the poles 2c and 2d. And in the lower part of

pole

2c, 2i, 2j, 2d, between each is connected by the small beam 4c. A screen 7 is formed between the poles 2i and 2j. The screen 7 is a projection surface of the projector 8 that is installed suspended from the beam 3g. In consideration of the load on the beam 3g due to the weight of the projector 8, beams 3h and 3i are provided between the beam 3g and the beam 3d for reinforcement. The signal to the projector 8 is given from a computer stored in the shelf 6.

As described above, the spatial structure 1 is a structure in which information devices such as a computer and a projector 8 are incorporated and appropriately combined with a pole, a beam, and a small beam according to the purpose of use. Therefore, the spatial structure 1 is not limited to that shown in FIG. 1 and is appropriately designed according to each purpose of use.

<< Pole >>
FIG. 2 is an external view of the pole 2, and FIG. 3 is a cross-sectional view of the pole 2. The pole 2 has a shape equally divided into four in its cross section. A partition wall 21 extends radially from the central portion 20 to form a square apex P in the cross section of the pole 4. The wall surface 22 extends from one vertex P toward the adjacent vertex P. The wall surface 22 extending from one vertex P and the wall surface 22 extending from the other vertex P adjacent thereto extend to an intermediate position between both vertices P, and they do not contact each other. Accordingly, an opening 23 is formed between the opposing wall surfaces 22 and 22 (hereinafter referred to as “a pair of wall surfaces 22”). Further, a groove portion 24 is formed by the pair of wall surfaces 22, the partition wall 21, and the central portion 20. These openings 23 and grooves 24 extend over the entire length in the axial direction of the pole 2 as shown in FIG.

Furthermore, at each vertex P of the cross section of the pole 2, two outer wall surfaces 25 extending from each vertex P to the outside of the pole 2 and orthogonal to the two wall surfaces 22 connected to the vertex P are provided. As a result, the outer wall surface 25 extending from one vertex P and the outer wall surface 25 extending from the other vertex P adjacent thereto are opposed to each other. Then, the facing outer wall surface 25 and the pair of wall surfaces 22 connected thereto form a wiring groove 26 which is a semi-closed space on the surface of the pole 2. In the wiring groove 26, it is possible to store a power cable and a signal cable of information equipment used in the spatial structure 1. Further, when the cable is housed in the wiring groove 26, the design of the appearance is deteriorated. Therefore, the wiring cover shown in FIG. 3 may be provided so as to cover the wiring groove 26.

<< Beam >>
FIG. 4 is an external view of the beam 3, and FIG. 5 is a cross-sectional view of the beam 3. The cross-sectional shape of the beam 3 is almost the same as the cross-sectional shape of the pole 2. The central portion 30, the partition wall 31, the wall surface 32 (a pair of wall surfaces 32), the opening portion 33, the groove portion 34, and the apex Q of the beam 3 are the center portion 20, the partition wall 21, the wall surface 22 (a pair of wall surfaces 22), and the opening. Since they correspond to the portion 23, the groove portion 24, and the apex P, detailed description thereof will be omitted.

In the beam 3, the configuration of the wiring groove for storing the power cable and signal cable of the information equipment used in the spatial structure 1 is different from that of the pole 2. In the beam 3, as shown in FIG. 5,

wiring grooves

36 and 38 are formed only in two directions, ie, vertically upward and vertically downward. Here, the height of the outer wall surface 35 constituting the wiring groove portion 36 in the vertically upward direction (the height of the outer wall surface 35 from the apex Q) is the height of the outer wall surface 37 constituting the wiring groove portion 38 in the vertically downward direction. It is designed to be higher than the height (the height of the outer wall surface 37 from the apex Q). This is because, when the beam 3 is incorporated into the spatial structure 1, the wiring groove 36 opens in the vertical upward direction, so that it is preferable that more cables can be accommodated. Of course, it is possible to store the cable in the wiring groove 38 in the vertically downward direction. However, since the design of the appearance is deteriorated, the wiring cover shown in FIG. 5 is provided to cover the wiring groove 38 in that case. May be. In addition, the wall surface corresponding to the outer wall surfaces 35 and 37 is not provided on the surface of the beam 3 in the horizontal direction, and there is no wiring groove.

<< Small beam >>
FIG. 6 is an external view of the small beam 4, and FIG. 7 is a cross-sectional view of the small beam 4. The cross-sectional shape of the small beam 4 is such that the horizontal direction of the beam 3 is the same and the vertical direction is compressed. That is, the beam is thinner than the beam 3. The center portion 40 of the small beam 4, the partition wall 41, the wall surface 42 (a pair of wall surfaces 42), the opening portion 43, the groove portion 44, and the vertex R are the center portion 30 of the beam 3, the partition wall 31, the wall surface 32 (a pair of wall surfaces 32), It corresponds to the opening 33, the groove 34, and the apex Q, respectively. Further, the small beam 4 is not provided with a space corresponding to the

wiring grooves

26, 36, and 38.

<< Corner Corner Connection >>

And as shown in FIG. 10, the joint 10 is connected with the beam 3 with a screw | thread. Further, the joint 10 is provided with a beam guide portion 10 c that fits into an end portion of the wiring groove portion 38 of the beam 3 when the installation surface 10 b comes into contact with the end surface of the beam 3. As shown in FIG. 10, the beam guide portion 10 c is fitted into the wiring groove portion 38, thereby facilitating work when the beam 3 is connected to the joint 10. The installation surface 10 b, the beam guide portion 10 c, and the through hole 10 e are provided at four locations in the joint 10 according to the shape of the pole 2.

In addition, when connecting the joint 10 to the pole 2 with a screw, as shown in FIG. 9, a screw is inserted from the opening part of the upper part of the joint 10, and a connection operation | work is performed. In addition, when the joint 10 is connected to the beam 3 with a screw, a screw is inserted from the opening at the top of the joint 10 to perform the connecting operation, or the through hole 10e located at a position facing the through hole 10e used for the connection.

The joint 51 is provided with a support portion 51a for supporting the joint 52, and a screw hole 51b for connection with the joint 52 on the support portion 51a.

<< Slide coupling device >>
FIG. 15 shows a state where the slide coupling device according to the embodiment is fixed to the groove. FIG. 16: shows the figure explaining a mode that the slide coupling device based on embodiment is fixed to a groove | channel. FIG. 17 is a perspective view of the auxiliary member of the slide coupling device according to the embodiment. FIG. 18 is a top view of the auxiliary member of the slide coupling device according to the embodiment. FIG. 19 shows a side view of FIG. FIG. 20 is a sectional view taken along the line II in FIG. Hereinafter, the pole 2 will be described as an example.

The slide coupling device 700 includes a base member 701 and an auxiliary member 710. As shown in FIG. 16, the base member 701 has a quadrangular shape in a plan view, and a screw hole 702 is provided at the center. The screw hole 702 corresponds to the connecting portion of the present invention. The length of the screw hole 702 corresponds to the thickness of the base member 701, and the thickness of the base member 701 is formed thicker than a conventional base member (for example, the base member described in Japanese Patent No. 4332148). . As a result, the strength of the base member 701 is also improved as compared with the prior art. A step formed at the end of the surface of the base member 701 (the surface of the groove 24 on the opening 23 side) (both ends in the width direction of the groove 24) one step lower than the surface along the longitudinal direction of the groove 24. Attached portion 703 is provided. The distance between the two stepped portions 703 is designed to be slightly smaller than the width of the opening 2 of the pole 2 or the beam 3. Each stepped portion 703 engages with the wall surface 22 forming the opening 23. Thereby, the base member 701 is restricted from moving in the groove 24 in the width direction of the groove 24. Further, the end portions (both ends in the width direction of the groove portion 24) of the back surface of the base member 701 (the surface on the back side of the groove portion 24) are chamfered 704 so as to match the shape of the groove whose width becomes narrower toward the back. ing. The base member 701 may be made of metal or resin. Note that the base member 701 may have a simpler shape by omitting the stepped portion 703 and the chamfer 704.

The auxiliary member 710 includes a main body part 711 on which the base member 701 is placed in the groove part 24 and two arm parts 712 extending from the end of the main body part 711. The auxiliary member 710 is made of a flexible plate-like resin, and the main body portion 711 and the arm portion 712 are integrally formed. The main body portion 711 is curved so as to protrude to the back side of the groove portion 24. The main body 711 is designed to have an area larger than the surface area of the base member 701 so that the base member 701 can be placed thereon. A screw hole 713 of the main body through which the screw 750 passes is provided at the center of the main body 711, in other words, at a position corresponding to the screw hole 702 of the base member 701. A plurality of screw holes 713 may be provided. Further, a thick part 715 formed thicker on the side of the opening 23 than the periphery is provided on one side of the main body 711. The thick portion 715 functions as a region that pushes the auxiliary member 710 when the auxiliary member 710 is attached (accommodated) to the groove portion 24 while restricting movement of the base member 701 to be placed in the width direction of the groove. . The auxiliary member 710 can be easily attached to the groove portion 24 by pushing the thick portion 715. The thick part 715 also functions as a fulcrum when the arm part 712 is picked and the auxiliary member 710 is taken out from the groove part 24. That is, the thick part 715 comes into contact with the inner wall surface of the groove part 24 and serves as a fulcrum.

The main body 711 also has a thick portion 715 and another bent portion 714 in contact with the inner wall of the groove 24, and urges the inner wall of the groove 24 toward the outside of the width of the groove 24. As a result, the auxiliary member 710 is temporarily fixed in the groove 24. More specifically, when the main body 711 does not place the base member 701 (only the auxiliary member 710 is accommodated in the groove 24), the thick portion 715 and the bent portion 714 are formed on the inner wall of the groove 24. Among these, the inner wall of the groove part 24 is urged toward a region (vertical surface) where the width of the groove part 24 is constant toward the outside of the width of the groove part 24. Further, in a state where the main body portion 711 places the base member 701 (a state where both the auxiliary member 710 and the base member 701 are accommodated in the groove portion 24), the thick portion 715 and the bent portion 714 are the inner walls of the groove portion 24. Of these, the inner wall of the groove portion 24 is urged toward a region (inclined surface) where the width of the groove portion 24 gradually decreases toward the outside of the width of the groove portion 24. Note that in a state where the main body portion 711 places the base member 701, a part of the urging force is also generated on the back side of the groove portion 24 along the slope.

Further, the main body 711 is formed such that the length on one side is shorter than that on the other side. Specifically, in the main body 711, the length on one side of the virtual center line parallel to the longitudinal direction of the groove 24 passing through the center in the width direction of the groove 24 is longer than the length on the other side of the virtual center line. , The two arm portions 712 are formed shorter. In other words, one side of the main body 711 is notched on both sides in the longitudinal direction of the groove 24. Thus, the urging | biasing force is adjusted by forming a notch in part.

The arm portion 712 is provided at two places via bent portions 714 provided at both end portions on the other side opposite to the thick portion 715. The arm portion 712 is curved so as to protrude to the back side of the groove portion 24. In addition, a thick part 716 of the arm that swells toward the main body 711 is provided at the tip of the arm 712. The thick part 716 of the arm is exposed from the opening 23. Thereby, the slide connecting device 700 can be easily taken out from the groove portion 24 by pinching the thick portion 716 of the arm portion. Further, the base member 701 placed on the main body 711 is sandwiched between the two arm portions 712 on both sides in the longitudinal direction of the groove portion 24, and the movement of the groove portion 24 in the longitudinal direction is restricted. Further, the movement of the groove 24 in the width direction is restricted by the engagement of each stepped portion 703 and the wall surface 22 forming the opening 23. Further, the movement of the groove 24 in the back direction is restricted by the base member 701 and the opening 23. The state where the slide connecting member 700 is fixed to the groove portion 24 without using the screw 750 is slidable freely, unlike the case where the slide connecting member 700 is fixed using the screw 750, and this state can be said to be temporarily fixed.

Further, as shown in FIGS. 19 and 20, a space is formed between the main body portion 711 and the arm portion 712 in the vicinity of the bent portion 714. By forming this space, the arm portion 712 can be sufficiently bent toward the main body portion 711 side. As a result, the auxiliary member 710 can be easily taken out from the groove 24. The biasing force can be changed by appropriately adjusting the material and thickness of the auxiliary member 710, the area of the main body portion 711, the diameter of the screw hole 702 of the main body portion, the thickness and width of the arm portion 712, and the like.

<< Attachment and removal procedures for slide coupling device >>
There are roughly two procedures for attaching or removing the slide coupling device 700 to or from the groove 24. The first procedure is a method of attaching or removing the slide coupling device 700 from the ends of the pole 2, the beam 3, etc., as shown in FIG. When attaching, the base member 701 is inserted into the groove 24 from the end of the pole 2 or the beam 3 in a state of being placed on the auxiliary member 710. This state is a temporarily fixed state, and can be slid to an arbitrary place by applying force by holding it with a hand. When the position is determined, the positions of the holes of the predetermined external member 740 are aligned and fixed with screws 750. The state fixed with the screw 750 is the fixed state, and movement is restricted in the fixed state. Examples of the predetermined external member 740 include an optional member such as a projector in addition to the pole 2 and the beam 3. 16, 21, and 22, the external member 740 is shown in a simplified manner, and only the plate member located on the pole 2 side of the external member 740 is shown. When removing the slide coupling device 700 from the groove 24, the reverse procedure may be performed. That is, first, the fixing of the screw 750 is released, the external member is removed, and the slide coupling device 700 at an arbitrary position is slid to the end of the pole 2 or the beam 3.

The second procedure is a method of attaching and removing the slide coupling device 700 from the opening 23 of the groove 24 such as the pole 2 and the beam 3 as shown in FIGS. When attaching, first, the auxiliary member 710 is inserted from the opening 23 of the groove 24. At this time, first, the bent portion 714 side is inserted. Next, the thick part 715 side of the main body part is pushed into the groove part 24. At this time, the thick portion 715 of the main body can be easily pushed in by pushing it with a finger. When the main body 711 is accommodated in the groove 24, the base member 701 is then tilted 90 degrees and inserted into the groove 24. When the base member 701 is inserted, the holes of the predetermined external member 740 are aligned and fixed with screws 750. This completes the installation. The state before being fixed with the screw 750 is a temporarily fixed state, and can be slid to an arbitrary place by applying force by holding it with a hand. On the other hand, the state fixed with the screw 750 is a fixed state, and movement is restricted in the fixed state. When removing, the reverse procedure may be performed. As shown in FIG. 22, first, the fixing of the screw 750 is released, and the external member is removed. Next, when one arm 712 is lifted from the opening 23 and the base member 701 is shifted in the longitudinal direction of the groove 24, the base member 701 is separated from the main body 711. The separated base member 701 can slide more easily in the groove portion 24 than in the state where it is placed on the main body portion 711. Therefore, the base member 701 can be easily taken out from the groove portion 24. The base member 701 may be tilted from the opening 23 with fingers, and the base member 701 may be picked out. Next, the thick part 716 of one arm part 712 is picked with a finger, the arm part 712 is pulled, and the main body part 711 is pulled out from the groove part 24. This completes the removal. First, the thick part 716 of one arm part 712 is picked with a finger, and one arm part 712 is pulled out from the groove part 24. When one arm part 712 is pulled out from the groove part 24, the thick part 716 of the other arm part 712 is then picked up with a finger, and the other arm part 712 is pulled out from the groove part 24. When the two arm portions 712 are pulled out, the arm portion 712 may be pulled as it is, and the main body portion 711 may be pulled out from the groove portion 24.

<Effect>
According to the slide coupling device 700 according to the embodiment, the main body portion 711 on which the base member 701 is placed pushes the inner wall of the groove portion 24 toward the outside of the width of the groove portion 24. This pushing force becomes an urging force, and the auxiliary member 710 is temporarily fixed at an arbitrary position in the groove 24. That is, the movement due to its own weight is limited by an appropriate biasing force. When the auxiliary member 710 moves due to its own weight, labor for positioning and the like increases, but in the slide coupling device 700 according to the embodiment, such labor for positioning and the like can be omitted. That is, the working efficiency when assembling the spatial structure is improved. In addition, by configuring the base member 701 and the auxiliary member 710 as separate members that can be separated, the slide coupling device 700 can be moved more smoothly in the groove portion 24 in a state where both are separated. In the slide coupling device 700, the main body portion 711 on which the base member 701 is placed can be configured by a thin plate-like flexible member, and the arm portion 712 extends from the end of the main body portion 711. A sufficient storage space can be secured. Therefore, the base member 701 can be made thicker than before, and the strength of the base member 701 can be improved than before. Further, since the arm portion 712 extends from the end portion of the main body portion, movement of the groove portion 24 of the base member 701 placed on the main body portion 711 in the longitudinal direction can be restricted. Further, since the distal end portion of the arm portion 712 is exposed from the opening portion 23, the auxiliary member 710 can be easily taken out from the groove portion 24 by grasping the distal end portion of the arm portion 712. Further, by configuring the base member 701 and the auxiliary member 710 as separate members that can be separated, the base member 701 and the auxiliary member 710 can be separately placed in the groove portion 24. Therefore, even the base member 701 having an increased thickness compared to the conventional case can be easily inserted into the groove 24. That is, the slide coupling device 700 can easily perform the work of attaching to the groove part 24 and the work of taking out from the groove part 24.

<Modification>
As shown in FIG. 23, the thick part 716 of the arm part may extend over the opening part 23 to the wall surface 22 that forms the opening part 23 on the opposite side to the bent part 714. Thereby, the thick part 716 of the arm part can be engaged with the inner wall surface of the wall surface 22. As a result, the temporarily fixed state can be maintained more stably.

Also, for attachment of the external member 740 to the pole 2, the beam 3, etc., various joints disclosed in, for example, Japanese Patent No. 4332148 can be appropriately used instead of the above-described slide coupling device 700.

In the embodiment, the spatial structure 1 has been described as an example, but the slide coupling device 700 can be widely applied as long as it is a member having the groove portion 24. For example, a frame made of a member having a groove can be installed on a desk, and a tray, a display, lighting, or the like for storing small items can be connected to the frame via a slide coupling device 700. Moreover, a shelf and a desk can also be comprised by combining the member which has the groove part 24. FIG. In this case, the slide coupling device 700 can be used as a coupling member between members.

The preferred embodiments of the present invention have been described above, but the slide coupling device according to the present invention is not limited to these, and can include combinations of these as much as possible.
