Description

  The present invention relates to a joining structure between members and an assembling type storage body assembled using the same.

  As a joining structure of members used for furniture, furniture, etc., a joining structure using dowels and dowel holes is known. For example, a plate material for an assembly box in which a V-shaped groove is formed in the width direction of the plate, for example, one is used on the top plate side and the other is used on the bottom plate side. Both plate materials are formed into an L-shaped member by bending them at a V-shaped groove. Next, the two L-shaped members are arranged in a frame shape, and the dowels of the top plate portion are inserted into the dowel holes of the side plate portion, and the dowels of the bottom plate portion are inserted into the dowel holes of the side plate portion. (Patent Document 1).

  However, since the joining structure of this member utilizes a cylindrical dowel and a cylindrical dowel hole, assembly requires skill and labor. To improve this, for example, a screw nut provided on one end of the dowel joint is fixed to a cap nut attached to the side plate, and the other end of the dowel joint is directed toward the tip. There is known a head having a frustoconical shape that spreads out and is joined by inserting the head into a joint recess provided on a shelf (Patent Document 2).

In this member joining structure, after the side plates to which the dowel joints are fixed are arranged face to face, the joining recesses of the shelf boards are press-fitted into the heads of the dowel joints to join the side boards and the shelf boards. Next, the back plate is fitted into a groove formed on the back side of the side plate. Further, the top plate and the base plate are arranged above and below the shelf plate and fixed with screws.
JP 2003-199640 A Japanese Patent No. 2805183

  However, since the joining structure of the conventional members is to join the dowels provided in one member together with the dowel holes provided in the other member, joining is complicated, and furniture using this joining structure Assembling and fixtures requires skill and effort. Moreover, the packaging of the member before an assembly is complicated and there exists a possibility that it may become bulky at the time of transportation and conveyance.

  An object of the present invention is that the members are compactly assembled before assembly and can be easily performed in a short time during assembly.

  In order to solve the above-described problems, the member joining structure of the present invention includes a protrusion provided in one member and a hole provided in the other member, and the both members rotate around the edge of one member. The side wall of the protrusion on the side away from the edge of the one member is temporarily fixed, and the edge of the hole on the side away from the edge of the one member is rotated around the edge of the one member. It is located inside the arc surface to be drawn sometimes, and the protrusion is joined by being inserted into the hole by the rotation.

  By doing so, both members are temporarily fixed so as to be rotatable around the edge of one member. For example, the other member can rotate around the edge of this member. The other member can be rotated around this edge. At this time, among the side walls of the protrusion of one member, the side wall of the protrusion on the side away from the edge of the rotation center of the other member is drawn when the edge of the hole on the side away from the edge of the rotation center rotates. Since it is located inside the arc surface, the protrusion provided on one member is inserted into the hole and joined without interfering with the edge of the hole provided on the other member.

  The assembling-type storage body according to the present invention has a rectangular shape in a plan view, a first plate and a second plate provided in parallel at a predetermined distance, and the first plate and the second plate. A pair of third plates joined to both ends, each of the pair of third plates being formed of one or a plurality of bendable plate units, and a bent portion of the plate units, between the plate units A joining portion, a joining portion of the first plate and a plate unit adjacent to the first plate, and a joining portion of the second plate and a plate unit adjacent to the first plate have a joining structure of the members. .

  By doing in this way, since the assembly type storage body is assembled in a compact manner before assembling, the efficiency of transportation and transportation is improved and the handling is easy. On the other hand, if the first plate of the assembly-type storage body assembled compactly is lifted upward, the bent portion of the plurality of pairs of bendable plate units constituting the third plate, the joint portion of the plate units, Since the joining portion of the first plate and the plate unit adjacent thereto and the joining portion of the second plate and the plate unit adjacent thereto have the member joining structure described above, The protrusion is inserted into the hole and joined. As a result, the assembly is easily performed in a short time.

  Next, the requirements of the present invention will be described in more detail. The protrusion provided in one member and the hole provided in the other member have a so-called dowel and dowel hole relationship. The shape of the protrusion provided on one member is such that, for example, when the other member rotates around the edge of the other member, the side wall of the protrusion away from the edge of the other member is the edge of the other member. If it is made to be located inside the circular arc surface which the edge of the hole of the side away from will draw, it will not be specifically limited.

  For this reason, the outside of the projection is chamfered, obliquely cut or curved. The protrusion has a columnar shape, and its cross-sectional shape is circular, elliptical, polygonal, or other irregular cross-sectional shape. The cross-sectional shape of the hole provided in the other member does not necessarily match the cross-sectional shape of the base end side of the protrusion provided in the one member, but the bonding strength increases when it matches.

  One member and the other member are temporarily fixed so as to be rotatable around the edge of one of the members. As a temporary fixing method, for example, a synthetic resin sheet coated with an adhesive or an adhesive, a metal sheet, a cloth or other flexible sheet may be used. These sheets are stuck around the edge of rotation.

  When the protrusions provided on one member and the holes provided on the other member are joined together, an adhesive may be applied to the holes. In this case, a capsule-type adhesive may be used as the adhesive. Capsule type adhesives are made by encapsulating an adhesive in a capsule such as a crushable (crushable) synthetic resin and inserted into a hole provided in the other member. The capsule adhesive should be temporarily fixed or fixed in the hole to prevent it from falling off. When the protrusion provided on one member is inserted into the hole provided on the other member, the capsule-type adhesive capsule is crushed and the sealed adhesive flows out and penetrates into the gap between the protrusion and the hole. Be joined.

  As the material of the adhesive, for example, vinyl acetate type, vinyl acetate / acrylic type, ethylene / vinyl acetate type, acrylic / ethylene type, urethane type or the like is used, and is determined in consideration of the material of the member to be bonded.

  The material of one member and the other member or the first plate, the second plate, the third plate, a plurality of pairs of plate units, for example, plywood, wood fiber board (MDF etc.), wood chip board, Single-layer laminates such as wood, synthetic resins such as styrene resin, vinyl chloride resin, reinforced plastic, expanded polystyrene resin, and expanded urethane resin can be used alone or in combination of two or more. .

  According to the present invention, before assembling, members are gathered in a compact manner, and assembly can be easily performed in a short time.
