  When building a shared space such as a conference space or exhibition space using information equipment in an office or exhibition hall, design the spatial structure based on the introduction of dimensions and weight of the information equipment used there. It is normal. For example, even when a display is used as an information device, the size, weight, number of units used, and the like vary depending on the purpose of use of the space. Therefore, the spatial structure is designed to have a shape corresponding to each.

  However, because of recent rapid development of information devices, new information devices appear one after another, and new functions are added or downsized even with conventional information devices. Updated. As a result, in a spatial structure using these information devices, the spatial structure must be redesigned in accordance with changes in dimensions and shape due to the appearance of new information devices. And since the conventional spatial structure is designed corresponding to specific information equipment as mentioned above, the redesign becomes very difficult.

  In the present invention, in view of the problems described above, in a spatial structure configured using information equipment, it is possible to flexibly cope with the appearance of new information equipment, the update of the information equipment, etc. An object of the present invention is to provide a connecting device for connecting members constituting the space structure, which can be designed.

  In order to solve the above-mentioned problem, in the present invention, in the columnar body and the lateral beam body constituting the spatial structure, a groove extending in the axial center direction is provided in the columnar body and the lateral beam body, and the position can be moved to an arbitrary position within the groove. The connecting means that can be fixed by the above is provided. By adopting such a configuration of the spatial structure, it becomes easy to adjust the configuration of the spatial structure as appropriate, and thus it is possible to flexibly cope with the update of information equipment.

  In detail, the present invention is such that one or more columnar bodies extending upward from a floor and one or more horizontal beam bodies extending horizontally in the floor are connected to each other and / or the horizontal beam bodies are connected to each other. The columnar body is a semi-closed space that extends along the axial direction in a part or all of the axial direction and has an opening in a cross section of the columnar body. A transverse beam having one or more columnar body groove portions, the transverse beam body being a semi-closed space extending along the axial direction in a part or all of the axial direction and having an opening in a cross section of the transverse beam body There is one or a plurality of body groove portions, and the connection between the columnar body and the horizontal beam body is arbitrary in the axial direction inside the columnar body groove portion of the columnar body or the horizontal beam body groove portion of the horizontal beam body. The connecting means that can move to the position and can be fixed to the position, The horizontal beam body is connected to the columnar body or the horizontal beam body on the side where the connection means does not exist through the opening of the columnar body groove portion or the horizontal beam body groove portion where the connection means exists. The connecting means that can move the inside of the transverse beam body groove portion of any of the transverse beam bodies to an arbitrary position in the axial center direction and can be fixed to the position of the transverse beam body groove portion where the connecting means exists. This is done by being connected to the lateral beam body on the side where the connecting means does not exist through the opening.

  The spatial structure is configured by a combination of a columnar body and a horizontal beam body. The configuration is appropriately adjusted according to the purpose of the spatial structure and the strength required of the structure. Further, the overall shape of the spatial structure is not limited to a rectangular shape, and can be applied to various shapes such as a polygonal shape, a radial shape, and the like.

  Here, the columnar body constituting the spatial structure has a columnar groove portion. A plurality of the columnar body groove portions may be provided in the columnar body.In that case, the cross-section of the columnar body is equally divided into a plurality of portions, and the columnar body groove portions are formed along the longitudinal direction of the columnar body for each divided portion. It is preferable to provide it. By doing in this way, in a space structure, it becomes possible to connect a horizontal beam body regularly using each columnar body groove part, and it can contribute to unitization of a space structure, improvement in design nature, etc. Moreover, the cross beam body which comprises a space structure also has a cross beam groove part. A plurality of the transverse beam body groove portions can be provided in the transverse beam body in the same manner as the columnar body groove portions.

  These columnar body groove portions and transverse beam body groove portions have openings in their cross sections, and the openings extend in the same manner along the direction in which both groove portions extend. In addition, this opening part does not need to exist over the full length of a columnar body and a horizontal beam body, and may exist partially in those longitudinal directions.

  The feature point in the spatial structure according to the present invention composed of the columnar body and the horizontal beam body described above lies in the connection method between these members. In this space structure, the connection between the members is performed by a connecting means. In addition, there are two types of connection between members in the space structure, that is, a columnar body and a cross beam body, or cross beam bodies. This does not prevent members other than the columnar body and the horizontal beam body from constituting the space structure. Then, information equipment and other members are incorporated into the space structure, and a space having a specific purpose is constructed.

Here, the connecting means can move the inside of the columnar body groove portion or the transverse beam body groove portion to an arbitrary position. And it can fix at that position while moving. Therefore, the positions of the columnar body and the horizontal beam body that make up the spatial structure become variable as the connecting means moves, so that it is possible to respond flexibly to changes in dimensions and shape due to the update of information equipment. It becomes. In addition, by providing new connection means in the columnar body groove part and the horizontal beam body groove part, it becomes possible to add a further horizontal beam body to the columnar body and a further horizontal beam body to the horizontal beam body. The reinforcement etc. can be performed easily.

  In addition, the opening exists to allow the connected columnar body or the horizontal beam body to access the connection means for the purpose of connection when the connection means is fixed to the columnar body groove portion or the horizontal beam body groove portion. To do. Therefore, the shape and dimensions of the opening are determined with a minimum range that can satisfy the purpose. Further, the connecting means may be provided in the columnar body groove portion or the transverse beam body groove portion through this opening, or may be disposed inside these from an insertion port provided individually.

  Here, when the spatial structure according to the present invention is viewed from another side, it extends upward from the floor, extends along the axial direction in part or all of the axial direction, and has an opening in the cross section of the columnar body. A columnar body having one or a plurality of columnar body groove portions having a semi-closed space, and extending in the horizontal direction on the floor, extending along the axial direction in part or all of the axial direction, and of the transverse beam body A transverse beam body having one or a plurality of transverse beam body groove portions that are semi-closed spaces having an opening in a cross section, and a columnar body groove portion of the columnar body or an inner portion of the transverse beam body groove portion of the transverse beam body in the axial direction A connecting means that can be moved to any position and fixed at the position, and when the connecting means is present in the columnar groove, the opening is formed through the opening of the columnar groove. And / or connected to the transverse beam body When present in the crossbeam body groove, the column bodies or transverse beam body through the opening of the lateral beam member groove is intended to be connected to another horizontal beam body.

  This spatial structure can be designed as a specific spatial structure by appropriately connecting and connecting the columnar body and the horizontal beam body according to the purpose of use of the spatial structure described above. It becomes. And these columnar bodies and horizontal beam bodies are connected by the connecting means constituting the spatial structure. Therefore, a connection means comprises the spatial structure which concerns on this invention according to the number of the combination of a columnar body and a horizontal beam body, and a horizontal beam body and a horizontal beam body.

  Due to the presence of the connecting means, even in the spatial structure described above, the positions of the columnar body and the horizontal beam body constituting the spatial structure are variable as the connecting means moves in the columnar body groove portion and the horizontal beam body groove portion. Therefore, it becomes possible to respond flexibly to changes in size and shape due to the update of information equipment. In addition, by providing new connection means in the columnar body groove part and the horizontal beam body groove part, it becomes possible to add a further horizontal beam body to the columnar body and a further horizontal beam body to the horizontal beam body. The reinforcement etc. can be performed easily.

  In the above spatial structure, in the case where an optional member that is a member other than the columnar body and the horizontal beam body and constitutes a part of the spatial structure is further provided, the connecting means is present in the columnar body groove portion. When connected to the optional member through the opening of the columnar body groove, and / or when present in the horizontal beam body groove, it is connected to the optional member through the opening of the horizontal beam body groove. It may be.

  The optional member is, for example, a member for fixing and holding an information device, a decorative member, or the like incorporated in the spatial structure, and may be a member that can finally exist as a part of the spatial structure. Also in the incorporation of the option member into the space structure, the option member can be connected to the columnar body or the horizontal beam body by using the connecting means. That is, the connecting means is useful for connecting any member that directly or indirectly constitutes the spatial structure.

In particular, the option member is a member that is suspended in a vertically downward direction, and when the horizontal beam body has a horizontal beam body groove portion whose opening portion is opened in the vertical downward direction, the connecting means includes the horizontal beam body groove portion. And may be connected to the optional member through the opening of the lateral beam groove. Examples of such an optional member include a projector that projects a personal computer screen onto a screen, a lighting device, a display device such as a liquid crystal screen, and the like. Sufficient strength is required for the horizontal beam body that supports these optional members because they are suspended vertically below the optional members. Therefore, when the weight of the optional member is increased, the appropriate design change such as connecting the optional member with the connecting means after changing the cross beam body connected to the optional member to one with stronger strength Can be easily performed in the spatial structure according to the present invention.

  Here, in the spatial structure described above, the connecting means includes a base member that can move inside the columnar body groove portion or the horizontal beam body groove portion, and an opening portion of the columnar body groove portion or the horizontal beam body groove portion. A biasing member that biases in the vicinity, and the base member and the biasing member may be separable from each other.

  When the base member moves in the columnar body groove portion or in the cross beam body groove portion, the connecting means can move to an arbitrary position in the groove portion. Then, by urging the base member in the vicinity of the opening of each groove by the urging member, the connecting means can be fixed at the arbitrary position. Further, by configuring the base member and the biasing member as separate members that can be separated, the base member can be smoothly moved in the respective grooves when the two members are separated, and the biasing member is separated from the base member. In the contacted state, the urging force is exerted on the base member by the urging member, and the connecting means can be surely fixed.

  Further, in the spatial structure according to the present invention, the connecting means includes a first contact portion that contacts one end surface that forms one end of the opening of the columnar body groove portion or the transverse beam body groove portion, and one end of the opening portion. A structure having a second contact portion that contacts the other end surface that forms the other end opposite to each other, and a pressing means that presses the first contact portion against the one end surface and simultaneously presses the second contact portion against the other end surface. But you can.

  As described above, the opening is an opening extending in the axial direction of the columnar body or the horizontal beam body. In other words, the opening is constituted by the one end face and the other end face facing each other across the opening. Therefore, when the connecting means is movable in the columnar body groove portion or the horizontal beam body groove portion, the pressing action by the pressing means is prevented from acting, and when in the fixed state, the pressing action by the pressing means is activated. It is to make.

  Further, in the spatial structure up to the above, the transverse beam body has at least two transverse beam body groove portions in which the opening portions are opened in two directions of a vertically downward direction and a vertically upward direction, and each of the two transverse beam body groove portions. Is provided with opposing walls provided along the axial direction of the horizontal beam body and projecting from the horizontal beam body groove portion and facing each other, the height of the opposing wall of the horizontal beam body groove portion opened vertically upward is vertical You may make it become higher than the height of the opposing wall of the horizontal beam body groove part opened downward.

  Wiring such as information equipment incorporated in the space structure can be accommodated in the space sandwiched between the opposing walls of the groove portion opened vertically upward. On the other hand, it is possible to accommodate, for example, a lighting device having a shape along a horizontal beam body in a space sandwiched between opposing walls of a groove portion opened vertically downward. And, by making the height of the facing wall of the groove portion opened vertically upward higher than the height of the facing wall of the groove portion opened vertically downward, it is possible to accommodate more wiring without impairing the appearance. Become.

Here, a slide coupling device that also functions as a coupling portion in the spatial structure according to the present invention is disclosed. This slide coupling device is a slide coupling device that can be moved to and fixed to an arbitrary position along a groove within a groove that is surrounded by an inner wall in a cross section and has an opening in a part thereof. A base member having a connecting portion for connecting to the member; and a biasing member configured to be separable from the base member and biasing the base member toward the inner wall near the opening in the groove. When the base member is pressed against the biasing member, the connecting portion is in a state of being connectable to the external member through the opening.

  When the base member moves in the groove, 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 surely set in a fixed state. When the slide connecting device is in this fixed state, the connecting portion is positioned in the opening so that the connecting portion of the base member can be connected to the external member. Examples of the external member here include the columnar body, the horizontal beam body, and an optional member.

  In the above slide coupling device, the urging member includes an urging portion that generates an urging force with respect to the base member, a first protrusion protruding from the urging portion toward the opening, and the urging force. A second projecting portion projecting to the back side of the groove opposite to the opening, and when the base member is located on the first projecting portion side of the biasing portion, When the biasing force is exerted on the base member by the biasing portion and the base member is released from the biasing position on the first projection portion side, the movement of the base member in the groove is restricted by the second projection portion. However, it may be possible to move in the groove.

  That is, the urging portion of the urging member applies the urging force in the direction in which the first protrusion protrudes. Then, by separating the urging member and the base member, that is, the base member is disengaged from the urging position on the first projecting portion side, the urging force by the urging member does not act on the base member. At this time, it is also possible to adjust the position of the base member from the outside via the biasing member by the first protrusion protruding to the opening side. On the other hand, since the base member does not receive the biasing force at this time, it can move relatively freely in the groove. In some cases, the base member may be far away from the base member, which may hinder the functioning of the slide coupling device. Therefore, by providing the second projecting portion, the movement of the base member in the groove is limited, and the base member is prevented from moving away from the slide member. In particular, when the groove is formed in the vertical direction, gravity acts on the base member, and there is a possibility that the groove always falls in the vertical downward direction. In such a case, the second protrusion is useful.

  Further, in the above slide coupling device, the urging portion includes the groove when the base member is located on the first protrusion portion side of the urging portion as compared with the case where the base member is not located on the first protrusion portion side. A biasing force may be exerted on the base member by bending inward. The urging force by the urging unit is not limited to this form.

  The first protrusion may be provided on the opposite side of the second protrusion with the urging portion interposed therebetween in the longitudinal direction of the groove. By doing in this way, it becomes possible to prevent more reliably the movement in the groove | channel of the base member which remove | deviated from the said biasing position.

  A space structure that uses information equipment can flexibly respond to the appearance of new information equipment and the renewal of the information equipment, making it possible to design a new space structure easily and constructing that space structure It is possible to provide a connecting device for connecting the members to be connected.

  Here, the Example of the spatial structure which concerns on this invention is described based on drawing. FIG. 1 is a diagram showing 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 its four corners and long sides. And the top part of these poles 2a-2f is connected by the seven beams 3a-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.

  Further, 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 according to the present invention is not limited to the one shown in FIG. 1, and is appropriately designed according to the purpose of use. Below, the detailed structure of a pole, a beam, and a small beam, and these connection methods are demonstrated.

  First, the pole 2 will be described with reference to FIGS. 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 to it extend to the middle before both the 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 toward 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.

  Next, the beam 3 will be described with reference to FIGS. 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 the 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 also 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. 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.

  Next, the small beam 4 will be described with reference to FIGS. 6 and 7. 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 central portion 40 of the small beam 4, the partition wall 41, the wall surface 42 (a pair of wall surfaces 42), the opening 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.

  Here, the connection of the pole 2, the beam 3, and the small beam 4 constituting the spatial structure 1 will be described. First, the connection of each element in each corner portion of the space structure 1 will be described with reference to FIGS.

FIG. 11 is a diagram showing a state of connection between the pole 2 and the small beam 4 in the lower part of the pole 2 (for example, connection between the pole 2a and the small beam 4a in the space structure 1). 11 to 13 are diagrams showing details of the connection between the pole 2 and the small beam 4.

  The pole 2 and the small beam 4 are connected through joints 50, 51 and 52. The joint 50 is a joint connected to the end of the pole 2 as shown in FIG. The joint 50 includes a contact surface 50 a having a through hole 50 b corresponding to a screw hole provided in the central portion 20 of the pole 2. The joint 50 is provided with four sets of opposing outer wall surfaces 50c similar to the opposing outer wall surface 25 of the pole 2. Further, there is no opening such as the opening 23 of the pole 2 between the opposed outer wall surfaces 50c, and screw holes for fixing the joint 51 described later are provided.

  When the joint 50 is connected to the end of the pole 2, as shown in FIG. 12, the joint 51 is fixed using the screw hole for fixing the joint 51 provided in the joint 50 and the through hole on the joint 51 side. 51 is connected to the joint 50.

  Further, the joint 60 is provided with a beam guide portion 60 d that fits into the end portion of the wiring groove portion 38 of the beam 3 when the installation surface 60 a comes into contact with the end surface of the beam 3. By fitting the beam guide part 60d into the wiring groove part 38, the work when the beam 3 is connected to the joint 60 becomes easy. A screw hole 60e for connecting the joint 62 described later and the joint 60 is provided inside the beam guide portion 60d.

  17 shows the detailed structure of the joint 61, and FIG. 18 shows the detailed structure of the joint 62. These joints function jointly, and the state is shown in FIGS. The joint 61 includes a flat base portion 61a, a claw portion 61b protruding upward from one end of the base portion 61a, and a guide portion 61c extending downward from the other end of the base portion 61a opposite to the claw portion 61b. And have. The base portion 61a is provided with a screw hole 61d.

  The joint 62 is provided with a rectangular through hole 62b in the vicinity of the upper center of the base portion 62a. The lateral width of the through hole 62b is a width that can be accommodated by the joint 61. And the guide groove 62c extended in an up-down direction is provided in the lower part of this through-hole 62b, and the lower base part 62d is further provided in the lower part. The lower base portion 62d protrudes from the guide groove 62c to the front surface, and a through hole 62e is provided on the surface thereof. Further, a protrusion 62f is provided at the upper part of the through hole 62b, and a through hole 62g (see FIG. 20) extending in the vertical direction is provided therein. Further, a claw portion 62h (see FIG. 20) protruding downward is provided on the back surface of the base portion 62a of the joint 62.

  The cooperative function of the joints 61 and 62 is as shown in FIG. That is, the claw portion 61b of the joint 61 and the claw portion 62h of the joint 62 are inserted into the groove portion 34 on the side surface side of the beam 3, and the claw portion 61b engages with the upper end surface 32 forming the groove portion 34. The joint 62 h is engaged with the lower end surface 32 forming the groove 34, so that both joints are fixed at an arbitrary position on the side surface side of the beam 3. How the joint functions of the joints 61 and 62 are performed will be described in detail with reference to FIG.

As shown in FIG. 20A, the joint 61 is inserted into the through hole 62b with the claw portion 61b of the joint 61 facing the through hole 62b. At this time, the joint 61 is inserted until the guide portion 61c of the joint 61 contacts the guide groove 62c of the joint 62 in a state where the claw portion 61b and the claw portion 62h are housed in the groove portion 34 of the beam 3. And the screw hole 61d of the joint 61 and the through-hole 62g of the joint 62 will be in the state located on the straight line in the up-down direction. Therefore, a screw is inserted from the through hole 62g toward the screw hole 61d, and the tip of the screw is in contact with the end of the guide groove 62c. Therefore, when the screw is rotated, the joint 61 moves relative to the joint 62 in the vertical direction in a state where the guide portion 61c slides on the guide groove 62c. As a result, the distance between the claw portion 61b and the claw portion 62h is adjusted by the rotation of the screw, and the engagement state between the both claw portions and the groove portion 34 (the end surface 32 forming the same) is controlled. Become.

  In other words, when the screw is adjusted to weaken the engaging force of the both claws to the groove 34, the joint 61 and the joint 62 cooperatively slide the opening 33 of the groove 34 on the side surface side of the beam 3, and arbitrarily It is possible to move to the position. Then, the joint 61 and the joint 62 can be fixed to the beam 3 at the arbitrary position by adjusting the screw to increase the engagement force between the both claws and the groove 34. That is, the joint 61 and the joint 62 correspond to the connecting means according to the present invention.

  By connecting the joint 60 installed in the other beam 3 to the joints 61 and 62 fixed to the one beam 3 in this way, the connection between the one beam and the other beam is executed. . Specifically, the two joints are screwed through the screw hole 60e of the joint 60 and the through hole 62e of the joint 62, whereby the beams can be connected to each other at an arbitrary position.

  Next, a method of connecting the pole 2 to the beam 3 in the spatial structure 1 in the middle thereof will be described with reference to FIGS. FIG. 21 is a diagram illustrating a state of connection between the beam 3 and the pole 2 (for example, connection between the beam 3a and the pole 2g in the spatial structure 1). 22 to 26 are diagrams showing the configuration of a joint and slide connecting device used for connecting the beam 3 and the pole 2.

  As shown in FIG. 21, the beam 3 and the pole 2 are connected through a joint 70 and a slide connecting device 71. Here, the joint 70 is a joint connected to the end of the pole 2 as shown in FIG. FIG. 22 shows a detailed structure of the joint 70. The joint 70 has an installation surface 70 a that comes into contact with an end surface of the joint 2 when installed on the pole 2, and the installation surface 70 a constitutes a base portion 70 b below the joint 70. The base portion 70b is provided with a through hole (not shown) that penetrates to the installation surface 70a. Further, the joint 70 is provided with a support portion 70d having a central portion opened on the base portion 70b having the installation surface 70a and having through holes 70c on both sides of the opening. The through hole provided in the base portion 70b can be accessed through the opening, and the through hole is located at the center of the pole 2 when the installation surface 70a is installed on the end surface of the pole 2. The position corresponding to the screw hole provided in the part 20 is taken. Therefore, it is possible to connect the joint 70 to the pole 2 with a screw.

  Further, the through hole 70c provided in the support portion 70d of the joint 70 corresponds to a screw hole (two screw holes on the left and right ends) provided in the slide connecting device 71, and the joint 70 and the joint 70 are screwed through these. The slide connecting device 71 is connected. When the slide connecting device 71 is relatively small with respect to the joint 70, two slide connecting devices 71 may be connected to one joint 70.

Here, details of the slide coupling device 71 will be described below. The slide coupling device 71 includes an urging member 72 shown in FIG. 23 and a base member 73 shown in FIG. The two are completely separate members. The urging member 72 includes an urging portion 72a having a contour shape, a protruding portion 72b protruding in one direction from the urging portion 72a, and a protruding portion protruding from the urging portion 72a in a direction opposite to the protruding portion 72b. 72c. The urging portion 72a is formed symmetrically with respect to a line connecting the points where the protrusion 72b and the protrusion 72c are provided. The specific shape of the urging portion 72a is a shape that slightly follows the center line of line symmetry in the vicinity of each protrusion (region indicated by R1 in the drawing), and further approaches the center of the urging portion 72a (in the drawing). The region indicated by R2 has an arc shape so as to be away from the line-symmetrical center line, and in the vicinity of the center of the urging portion 72a (region indicated by R3 in the figure), the shape is substantially parallel to the line-symmetrical center line. By adopting such a shape for the biasing portion 72a, the biasing portion in the region indicated by R3 is easily bent in the direction perpendicular to the drawing with the biasing portion in the region indicated by R1 as an axis. The biasing portion 72a can exert a biasing force in a direction perpendicular to the drawing. Further, the protrusion 72c has a substantially cylindrical protrusion shape, and the protrusion 72b has a shape having a slight lateral width than the protrusion 72c. This lateral width is slightly smaller than the width of the openings 23 and 33 of the pole 2 and the beam 3.

  As shown in FIG. 28, the base member 73 is provided with three screw holes 73b in the center of the base portion 73a. Furthermore, a stepped portion 73c is provided on the one end surface side of the base portion 73a along the longitudinal direction of the base portion 73a. The width of the stepped portion 73c (the width in the vertical direction in the drawing) is slightly smaller than the width of the openings 23 and 33 of the pole 2 and the beam 3.

  The function of the urging member 72 and the base member 73 as the slide connecting device 71 in the grooves 24 and 34 of the pole 2 and the beam 3 will be described with reference to FIG. FIG. 25 shows the state of the slide coupling device 71 in the beam 3, but since it is the same in the pole 2, the description thereof is omitted. The groove portion 34 of the beam 3 is formed by the inner wall surfaces of the partition wall 31 and the wall surface 32 extending from the central portion 30 as described above, and the cross-sectional shape thereof is substantially hexagonal. Here, as shown in FIG. 25, the substantially hexagonal apexes in the cross section of the groove 34 are referred to as S1 to S6, and the apexes constituting the opening 33 are referred to as T1 and T2.

  First, as shown in FIG. 25A, the urging member 72 is slid from the opening 33 with respect to the groove 34. At this time, the protrusion 72c is located in the back of the groove 34 (near the vertices S3 and S4), and the protrusion 72b is located in the vicinity of the opening 33 (between the vertices T1 and T2). Moreover, the part located in area | region R3 of the urging | biasing part 72a is located in the inner wall surface vicinity between vertex S1, S2 of the groove part 34, and between vertex S5, S6. At this time, since there is a slight gap between the urging portion 72a and the inner wall surface, the urging portion 72a is not bent.

  In the state shown in FIG. 25A, the biasing member 72 can be freely moved in the groove 34 of the beam 3 through the protrusion 72b. After the urging member 72 is moved to an arbitrary position of the groove 34, the base member 73 is inserted into the groove 34 as shown in FIG. At this time, the surface of the base member 73 where the stepped portion 73c of the base member 73 is not in contact with the surface of the biasing portion 72a of the biasing member 72 on the side where the protruding portion 72b protrudes. A stepped portion 73 c is located in the opening 33.

In the state shown in FIG. 25 (b), the urging portion 72a of the urging member 72 is pushed into the inner part of the groove 34 by the base member 73, so that the portion located in the region R3 of the urging portion 72a is the partition wall 31. Will contact the inner wall surface (between vertices S2 and S3 and between vertices S4 and S5). The width of the inner wall surface becomes narrower as it goes deeper into the groove 34. Therefore, in the state shown in FIG. 25 (b), the urging portion 72a of the urging member 72 bends as described above, and due to the bending, the urging portion 72a is displaced from the wall surface 32 near the opening 33. The urging force that presses against is generated. As a result, the slide coupling device 71 including the biasing member 72 and the base member 73 is fixed at an arbitrary position in the beam 3.

  Then, with respect to the screw hole 73b of the slide connecting device 71 fixed in the beam 3, the pole 2 to which the joint 70 is connected with a screw is sandwiched through the through hole 70 provided in the support portion 70d of the joint 70. By connecting, the pole 2 can be installed at an arbitrary position of the beam 3 as in the spatial structure 1 shown in FIG. From the above, the slide coupling device 71 corresponds to the coupling means according to the present invention.

  Here, the state at the time of changing the fixed position with respect to the slide coupling device 71 once fixed at an arbitrary position will be described with reference to FIG. First, as shown in FIG. 26A, the base member 73 to which the urging force is applied to the urging member 72 is shifted in the direction of the arrow to a position where the urging force is not applied from the urging member 72 completely. . At this time, when the groove 34 is viewed from the cross-sectional direction, it is as shown in FIG. The urging member 72 is in the state shown in FIG. 26B when the base member 73 is removed. At this time, the base member 73 exists in a space other than the space where the urging member 72 exists in the groove portion 34.

  However, as shown in FIG. 26B, the base member 73 is in a state of interfering with the protruding portion 72 c of the biasing member 72 in the groove portion 34. This means that even when the base member 73 is released from the urging force by the urging member 72, the base member 73 is not freely movable in the groove 34, and its movement is limited by the urging member 72. means. This is particularly important when the slide coupling device 71 is used in the groove 24 in the pole 2. Since the pole 2 extends in the vertical direction from the floor surface, gravity acts on the base member 73 released from the urging force. Therefore, there is a possibility that the base member 73 falls to the lower part of the pole 2. However, when the slide coupling device 71 is used in the groove portion 24 with the projection 72b side down and the projection 72c side up, the movement of the base member 73 is limited by the projection 72c as described above. It is possible to reliably prevent the member 73 from falling.

  In addition, after releasing the base member 73 from the urging force by the urging member 72, the base member 73 is removed from the opening 33, and the urging member 72 is moved to a new position, and then the base member 73 is changed to the groove portion 24, again. The slide coupling device 71 can be fixed by inserting it into the H.34.

  Next, a method of connecting the small beam 4 to the pole 2 in the spatial structure 1 in the middle thereof will be described with reference to FIG. As shown in FIG. 27, the connection between the pole 2 and the small beam 4 is performed via the joints 51 and 52 and the slide connecting device 71 described above. That is, the slide connecting device 71 is inserted into the groove 24 of the pole 2 as described above, and is fixed at a predetermined position. The small beam 4 to which the joint 51 and the joint 52 are connected is connected to the slide connecting device 71 using the through hole on the joint 51 side and the screw hole 73 b of the slide connecting device 71.

  Next, the connection of the projector 8 to the beam 3 in the spatial structure 1 will be described with reference to FIGS. As shown in FIG. 28, the projector 8 is connected to the beam 3 via joints 80 and 81. At this time, the slide connecting device 71 is provided in the groove 34 on the vertical downward side of the beam 3. Yes. That is, the joint 80 and the joint 81 are attached to the screw hole 73b of the slide coupling device 71 fixed in the groove 34, and the projector 8 is further coupled to the joint 81, so that the projector 8 3 are connected in a state of being suspended by 3.

Here, the structure of the joints 80 and 81 will be described with reference to FIG. The joint 80 has a T shape, and the upper horizontal portion 80b is provided with through holes 80a on both ends thereof. Further, the vertical portion 80d extending downward from the center of the horizontal portion 80b has a prismatic shape, and four surfaces thereof are provided with a total of eight screw holes 80d at the center and eight screw holes 80e at the bottom. ing. In addition, in the joint 81, two angle adjusting plates 81b are provided in parallel on the base plate 81a to which the upper part of the projector 9 is coupled. The angle adjustment plate 81b is provided with an adjustment groove 81c opened in an arc shape. Further, a support groove 81d is provided below the adjustment groove 81c.

  In the joints 80 and 81 configured as described above, the vertical portion 80c of the joint 80 is inserted between the two angle adjustment plates 81b. Then, a screw is screwed into the screw hole 80d provided in the central portion of the vertical portion 80c through the adjustment groove 81c of the joint 81. Further, the screw hole 80e provided in the lower portion of the vertical portion 80c is screwed with a screw through the back portion of the support groove 81d. Here, by rotating the posture of the joint 80 with respect to the joint 81 about the screw hole 80e, the relative posture of the two can be changed, and an arbitrary posture can be held by the screw. Then, by fixing the joints 80 and 81 adjusted to an arbitrary posture to the slide coupling device 71, the projector 8 can be suspended and fixed to the beam 3 after adjusting the tilt of the projector 8.

  In addition, screw holes 80d and 80e are provided on the four surfaces of the vertical portion 80c, respectively. Therefore, in connecting the joint 80 and the joint 81, by selecting two sets of surfaces of the vertical portion 80c, the orientation of the projector 8 can be adjusted by 90 degrees as shown in FIGS. 28 (a) and 28 (b). Is also possible.

  In addition, when it is desired to connect a plate-like panel such as the screen 8 or glass to the pole 2 or the beam 3, it may be performed as shown in FIG. In other words, the bracket 90 capable of fixing one of the fixing brackets 91 and 92 fixed with the panel interposed therebetween to the screw hole 73b of the slide coupling device 71 fixed in the grooves 24 and 34 of the pole 2 and the beam 3 is provided. And fixed to the slide connecting device 71 with screws. In this way, the plate can be connected to an arbitrary position of the pole 2 or the beam 3.

  In the spatial structure configured as described above, by using the slide coupling device 71, a new pole 2 can be coupled to the beam 3, or the position of the already coupled pole can be easily changed. Is possible. The same applies to the connection between the pole 2 and the small beam 4. The same applies to the connection of the beams 3 using the joints 60, 61, 62.

  As a specific example, in the spatial structure 1 shown in FIG. 1, it is assumed that the projector 8 that is an information device is changed to a new projector 800 with the update. The projector 800 is a device that has a longer focal length and a heavier weight than the projector 8. In such a case, in the spatial structure 1, the new beam 300 is passed between the beam 3b and the beam 3f using the joints 60, 61, and 62. Further, for reinforcement, a pole 310 is added at a position that supports the connecting portion between the beam 300 and the beam 3 f by using the slide connecting device 71. As described above, in the spatial structure 1 according to the present invention, the pole 2, the beam 3, and the small beam 4 constituting the space structure 1 can be appropriately added and the position can be easily adjusted due to the update of information equipment and other factors. .

As described above, the structure other than the spatial structure 1 shown in FIG. 1 can be formed by combining the pole 2, the beam 3, and the small beam 4 as described above. As shown in FIG. FIG. 32 shows a spatial structure 100 formed by a single pole 2. A display 101 and a table 102 are connected to the spatial structure 100. The display 101 and the table 102 can be fixed to any position of the pole 2 by using the above-described slide connecting device 71 for these connections. FIG. 33 shows a circular base plate 103 that is a support for the lower part of the pole 2. The size of the base plate 103 is determined by the length of the pole 2 and the load of the object fixed thereto.

  FIG. 34 shows a planar spatial structure 200 composed of two poles 2 and two small beams 4. The slide connecting device 71 is used for connecting the upper pole 2 and the small beam 4. An anchor base 201 is used to connect the lower pole 2 and the small beam 4. The anchor base 201 is a joint that is attached to the end surface of the pole 2, and can further connect the small beam 4 to which the joint 52 is attached via the joint 51.

  In addition, since a planar structure like the spatial structure 200 is easily collapsed, the support member 202 shown in FIG. 35 is connected by using a portion that is not used for connection with the small beam 4 of the anchor base 201. The By connecting the support member 202 to the pole 2, it is possible to prevent the space structure 200 from falling down.
