Description

  The present invention relates to a member connection structure, and more particularly to a member connection structure that connects two elongated members, one of which is orthogonal to the other.

  For example, in a metal article receiving table in which a rectangular receiving plate is fixed to the tops of four columns, when a shelf plate is arranged in the middle of the height direction, first, a member that receives the shelf plate is provided. It is necessary to attach to the column.

  And the attachment of the member which receives such a shelf board, for example, provides a recess or a notch at equal intervals along the height direction of the column, and a member for receiving a pin or hook-like shelf board in the recess or notch. A part is inserted and hung.

  However, in such a conventional mounting method, the position of the shelf board is regulated by the recesses and notches provided in the support columns, and when a plurality of shelf boards are arranged up and down, the interval between them cannot be finely adjusted. .

  In addition, for example, in the partition, the partition material is generally stretched between two support columns erected in parallel, but the partition material is configured by a single member. Therefore, I couldn't deny another feeling in terms of design. That is, as the partition material stretched between the columns, for example, a transparent material on the upper side is used, while an opaque material is used on the lower side, and each coloring is different, it is further improved in terms of appearance. As well as improving, it is possible to make a match that matches the place where it is used. Therefore, improvement of this point has been desired in the past.

  The present invention has been made in view of the above points, and when two elongated members are connected to each other in a state orthogonal to the other, one member is desired in the longitudinal direction of the other member. It is possible to connect to a desired position, so that it is possible to easily and quickly connect to a desired position, and thus to provide a member connection structure that can solve the above-mentioned conventional problems. It is something to be done.

  Thus, the gist of the present invention is that the two elongated members are connected to each other in a state of being orthogonal to the other, and one of the members is made hollow, and the end portion In addition, a cylindrical body having a size and shape suitable for fitting into the one member, a lateral protrusion at the tip portion, and a conical recess on the side surface near the rear end, A working rod fitted into the cylindrical body so as to be movable in the axial direction, and the cylindrical body is screwed so as to be screwed in a direction orthogonal to the working rod, and the tip is formed into a conical shape, and the tip of the conical shape A screw that faces the concave portion of the working rod, and a rear end side of the working rod in the cylindrical body, and the working rod is always in a direction in which its tip protrudes from the end surface of the cylindrical body. Fix the connecting member consisting of a pressure-enhancing spring that imparts mobility, with the tip of its working rod projecting, The side surface of the other member is provided with a recess along the length direction in which the protrusion of the working rod tip enters, and the recess is provided on the side surface of the recess. In the connecting structure of the members, an inward projection that enters between the projection at the tip of the working rod and the end surface of the cylindrical body in the connecting member is formed on the open side portion of the coupling member.

  According to the present invention, when two elongated members are connected in a state orthogonal to the other, one member can be connected to a desired position in the length direction of the other member. Therefore, for example, when a plurality of shelves are arranged in the middle of the height direction in a metal article receiving table in which a rectangular receiving plate is fixed to the tops of four columns, the interval between the upper and lower shelf plates is set. It can be freely adjusted. Also, the fixing and releasing of the connecting member can be done by simply turning the screw, so that the vertical position can be easily shifted.

  In addition, in the partition in which a partition material is stretched between two support columns installed in parallel, the edges of the two upper and lower plates are placed at desired positions in the height direction between the two support columns. The member which supports can be attached. Therefore, for example, if a transparent material is used on the upper side and an opaque material is used on the lower side and the coloring is made different, the appearance will be further improved, and depending on the place where it is used. It is possible to make a match.

  The best mode for carrying out the present invention is to make one member hollow, and at its end, a cylindrical body of a size and shape suitable for fitting into the one member, and a tip A side protrusion near the rear end is formed on the side surface, and a conical concave portion is provided on the side surface, and a working rod fitted into the cylindrical body so as to be axially movable, and the cylindrical body orthogonal to the working rod. A screw which is screwed so as to be screwed in a direction, the tip of which has a conical shape and the conical tip of which faces the recess of the working rod, and the rear end of the working rod in the cylindrical body A connecting member consisting of a pressure-enhancing spring that provides a mobility direction in a direction in which the tip of the working rod always protrudes from the end face of the cylindrical body. While fixing and further providing a notch hole on the side surface so that the screw of the connecting member is exposed, on the side surface of the other member, A concave portion is provided along the length direction in which the projection at the tip of the working rod in the connecting member enters, and a portion on the open side of the concave portion is provided between the projection at the tip of the working rod in the coupling member and the end surface of the cylindrical body. It is to form an inward projection that enters.
