Description

  The present invention relates to a connection structure between a plastic hollow plate and a structural material, and a partition to which the connection structure is applied.

  Conventionally, as a structure for connecting a plurality of plastic hollow plates to form a partition, a plastic hollow plate having a male member and a structural member which is a female member separate from the plastic hollow plate are provided. (For example, refer to Patent Document 1).

  More specifically, the plastic hollow plate has a protrusion at the end, and the protrusion and the groove are engaged with each other by inserting the protrusion into a groove provided in the structural material. The hollow plate and the structural material can be connected.

  Since this type of protrusion is required to be easily elastically deformed, the strength of the root portion may be weakened. On the other hand, if the wall thickness is increased in order to maintain the strength of the root part, the strength is ensured and the degree of breakage is only slightly reduced, but the protrusion is less likely to be elastically deformed due to the increase in wall thickness, and the connection is made. In some cases, it requires a great deal of force and may be a burden on the user.

  Due to the circumstances described above, in the configuration having the conventional protrusion, the movable width (so-called stroke) accompanying the elastic deformation of the protrusion is set to be relatively small in consideration of securing the strength and reducing the burden on the user. As a result, the engagement between the protrusion and the groove is weakened, and a problem that the protrusion easily comes off the groove may occur.

Specifically, as shown in FIG. 9, the hollow plate main body P1 includes a cap sheet s1 having a large number of cap-shaped protrusions t, one side (front side) and the other side (so that the cap sheet s1 is sandwiched). Two three-layered bubble boards P11 each provided with a flat back sheet s2 and a liner sheet s3 arranged on the rear surface side are overlapped. In addition, as for the hollow plate main body P1, any surface of the back sheet | seat s2 and the liner sheet | seat s3 may face the outer side. Further, the bubble board P11 may be overlapped so that the back sheets s2 face each other, or the bubble board P11 may be overlapped so that the liner sheets s3 face each other.

  The cap sheet s1 has a plurality of protrusions t arranged at regular intervals, and a plurality of bubbles a which are separated spaces are formed in cooperation with the back sheet s2 or the liner sheet s3. The hollow plate body P1 is composed of two bubble boards P11 that are overlapped with the positions of the bubbles a being shifted. A common groove member P2 is bonded to each end surface of the two bubble boards P11. As an example, in this embodiment, the common groove member P2 is connected by welding, whereby each bubble board P11 is fixed at a predetermined position. That is, the plastic hollow plate P can be made in a mode with excellent strength by stacking a plurality of bubble boards P11 and welding a single groove member P2 to the end faces of these bubble boards P11.

  The groove member P2 is formed of plastic, and is provided with a groove Z that is a tip member insertion portion that extends linearly in the vertical direction. The groove member P2 has a base portion P21 having a flat connection surface m1 connected by welding to the end surface of the hollow plate main body P1 and a convex shape in plan view, and is disposed on the tip side of the base portion P21. And a groove forming portion P22 in which a groove Z having an inner width w1 larger than the opening width w2 is formed.

  The base portion P21 has a wide portion P211 provided with a connection surface m1 on the rear side, and a narrow portion P212 projecting on the front side of the wide portion P211, and has a convex appearance in plan view. Forming.

  In the engaged state, the groove forming portion P22 includes a substantially U-shaped surrounding wall P221 that surrounds the bend portion 21 (described later in detail) of the tip member 2 in the structural material J, and a front end of the surrounding wall P221. A pair of leading end walls P222 extending in the direction of closeness and a connecting wall P223 projecting rearward from the rear end of the surrounding wall P221 and connected to the front end of the base portion P21 are provided. The connection wall P223 is formed narrower than the base portion P21. The distance between the tips of the tip wall P222 (that is, the opening width w2 of the groove Z) is set to be shorter than the width of the space formed by the surrounding wall P221 (ie, the inner width w1 of the groove Z).

  Subsequently, the structural material J will be described.

  The structural material J is made of plastic, and is set to have a vertical width of about 1 cm to 10 cm, for example. The structural material J includes a basic member 1 for holding another plastic hollow plate P having the same structure, and a distal end member 2 provided on the distal end side of the basic member 1 and engaged with the groove Z. . The structural material 1 includes a single basic member 1 having a bar shape extending in the vertical direction and tip members 2 respectively protruding from both ends of the basic member 1, which are integrally formed of resin. Yes.

  The basic member 1 supports the tip member 2 that is mainly elastically deformed when attached. The basic member 1 is formed to be thicker than the respective parts constituting the tip member 2.

  The tip member 2 is a part that engages with the groove Z of the groove member P2. The distal end member 2 includes a trunk side portion 211 extending from the trunk member 1 and a distal end side portion 212 extending from the extending end of the trunk side portion 211 so as to be folded back so as to form a substantially V shape in plan view. A bend portion 21 and a connection portion 22 that is interposed between the bend portion 21 and the distal end member 2 and has a portion with a shorter width than the trunk side portion 211. That is, the trunk side portion 211 extends from the trunk member 1 via the connection portion 22. The connecting portion 22 is set to be narrower than the basic member 1.

  The trunk-side portion 211 has a proximal end connected to the connecting portion 22 and a distal end connected to the distal end portion 212 via the bent portion 213 so that the width dimension in plan view gradually decreases toward the distal end. Is formed. At the base, that is, the base end portion of the trunk side portion 211, an overhanging portion 211 a that protrudes outward in order to expand in the groove Z is provided.

  The distal end side portion 212 extends rearward from the distal end of the distal end side portion 212 via the bent portion 213 and is formed so that the width dimension in plan view gradually increases toward the rear end side. At the tip of the tip end portion 212, that is, the rearmost portion of the tip end portion 212, an overhanging portion 212a that protrudes outward in order to expand in the groove Z is provided.

  In this embodiment, the backbone side portion 211 of the bend portion 21 is set to be thicker than the distal end side portion 212. For this reason, when the bend portion 21 receives a pressing force during the mounting operation with respect to the groove member P <b> 2, the distal end side portion 212 is more easily elastically deformed than the trunk side portion 211.

  The distal end of the distal end side portion 212 is a free end. That is, the bend portion 21 has a substantially V shape in a plan view, and the base end portion of the trunk side portion 211 that is one end of the V shape is connected to the connection portion 22. In other words, the bend part 21 is cantilevered by the basic member 1 via the connection part 22.

  The cap C is detachably disposed on the upper end portion of the side end edge of the plastic hollow plate P that is connected via the structural material J. The cap C can cover the entire structural material J, a part of the groove member P2, and a part of the hollow plate body P1 when viewed from above.

  The cap C has a flat plate-shaped covering portion C1 whose width dimension is set to be substantially the same as that of the narrow portion P212 of the base portion P21, and projects downward from the lower surface side of the covering portion C1. A groove engaging portion C2 having a columnar portion C21 inserted into the groove Z from the upper end side. The columnar portion C21 has a cylindrical shape and is inserted into the groove Z from the upward opening n1 provided in the groove forming portion P22. In this embodiment, the groove engaging portion C2 includes two columnar portions C21 and a connecting portion C22 that connects these columnar portions C21. The connecting portion C22 is set to a width that is slightly shorter than the opening width w2 of the groove Z of the groove forming portion P22.

  The leg bodies L and N have the same structure as the structural material J. The leg structural material k1 (hereinafter, the detailed reference numerals of the leg structural material k1 are the same as those of the structural material J), and the leg structure. The lower end surface of the material k1 is attached, and a plate-like leg plate k2 that is in contact with a grounding surface such as a floor is fixedly attached. When the distal end portion 2 of the leg structural member k1 bonded onto the leg plate k2 is attached to the plastic hollow plate P, it is inserted from the downward opening n2 provided in the groove forming portion P22.

  Next, an example of the procedure for assembling the partition M will be described.

  Two plastic hollow plates P having groove members P2 attached to both ends of the hollow plate main body P1 are prepared. And in order to connect these, the structural material J is arrange | positioned at two places up and down between the two plastic hollow plates P. FIG.

  First, the structural material J is attached to the plastic hollow plate P on one side. As shown in FIG. 7, the tip member 2 of the structural material J is pressed against the groove member P2 of the plastic hollow plate P on one side, and the bend portion 21 of the tip member 2 is pushed into the groove Z. Then, as shown in FIGS. 7 and 8, the outer wall of the bend portion 21 comes into contact with the opening of the groove forming portion P22, and the bend portion 21 receives a pressing force by the groove forming portion P22. The bend portion 21 that has received a pressing force from the outside mainly undergoes elastic deformation preferentially at the bent portion 213 and the distal end portion 212, and temporarily moves in a direction in which the distal end portion 212 approaches the trunk portion 211. To do.

  In other words, the V-shaped bend portion 21 is temporarily elastically deformed so that the V-shaped valley is narrowed by being pressed from the outside by the groove member P2 in the process of entering the groove Z of the groove member P2. To do. The wedge-shaped space between the distal end side portion 212 and the backbone side portion 211 mainly constitutes an elastic deformation allowable space that allows movement due to elastic deformation of the distal end side portion 212, and the elastic deformation allowable space forms a relatively long distal end. Strokes due to elastic deformation of the side portion 212 are allowed.

  In the process in which the bend portion 21 enters the groove Z of the groove member P2, the groove forming portion P22 formed of resin temporarily elastically deforms in the direction in which the surrounding wall P221 opens, that is, in the direction in which the opening of the groove Z opens. It is supposed to be.

  Thereafter, when the pressing operation on the structural material J is continued, the bend portion 21 enters the groove Z, and the bend portion 2 that has entered the groove Z returns by elastic deformation in the direction in which the V-shaped valley expands. The overhanging portions 211a and 212a of the trunk side portion 211 and the distal end side portion 212 are in contact with the inner surfaces of the surrounding wall P221 and the distal end wall P222 of the groove forming portion P22, respectively.

  The plastic hollow plate P on the other side is attached by attaching two structural members J to the plastic hollow plate P on one side and then pressing the plastic hollow plate P on the other side against the structural member J. The details regarding the connection between the plastic hollow plate P on the other side and the structural material J are as described above.

  Next, the cap C is attached to the connecting portion of both the plastic hollow plates P. The insertion of the cap C is completed by inserting the columnar portion C21 of the groove engaging portion C2 in the cap C from the upward opening n1 of the groove forming portion P22 in the groove member P2.

  Further, an intermediate leg L attached to the connecting portion and an end leg N attached to the end portion are attached to the plastic hollow plate P. Specifically, this is performed by inserting the bend portion 21 of the leg structural member k1 of the legs L and N into the downward opening n2 of the groove member P2.

  The assembly of the partition M is completed by the above procedure. Needless to say, the assembly procedure may be changed as appropriate.

  As described above, the connection structure between the plastic hollow plate P according to the present embodiment and the structural material J attached to the small end of the plastic hollow plate P is such that the plastic hollow plate P is disposed inside the small end. A groove Z in which the width w1 is set larger than the opening width w2 is provided, and the structural material J is provided on the base member 1 for holding another plastic hollow plate P, and on the distal end side of the base member 1 And a tip member 2 that engages with the groove Z. The distal end member 2 includes a trunk side portion 211 extending from the trunk member 1 and a distal end side portion 212 extending from the extending end of the trunk side portion 211 and is formed in a substantially V shape. The bend portion 21 is provided. Further, overhanging portions 211 a and 212 a for spreading in the groove Z are provided at the base of the trunk side portion 211 and the tip of the tip side portion 212. Therefore, it is possible to provide a connection structure between the plastic hollow plate P and the structural material J that can obtain a suitable connection state by a relatively smooth push-in, and a partition M to which the connection structure is applied.

  That is, the bend portion 21 formed in a substantially V shape passes through the opening width w2 of the groove Z by temporarily reducing the width dimension at the time of connection, and is elastic after passing through the opening width w2. The deformation returns to the original width dimension, and the overhanging portions 211a and 212a expand in the groove Z. For this reason, it becomes easy to take a large movable width (stroke) for engaging with the groove Z by the V-shaped bend portion 21, and the intended purpose can be achieved.

  The backbone side portion 211 of the bend portion 21 is set to be thicker than the distal end side portion 212. For this reason, the main movable part due to elastic deformation can be concentrated on the distal end side part 212 and the amount of deformation of the trunk side part 211 is reduced, so that the load does not fluctuate during pushing, contributing to the realization of stable pushing. To get.

  Since the plastic hollow plate P is provided with the hollow plate main body P1 and the groove member P2 having the groove Z provided on the small edge end surface of the hollow plate main body P1, the plastic hollow plate having the groove Z on the small edge end surface. The plate P can be suitably realized.

  Moreover, since the groove member P2 and the structural material J are each formed of plastic, they can be elastically deformed at the time of connection, and the groove member P2 and the structural material J cooperate with each other. A suitable connection structure can be realized.

  Since the groove member P2 is welded to the end face of the hollow plate body P1, the mounting strength between the groove member P2 and the hollow plate body P1, and the mounting work of the groove member P2 to the hollow plate body P1 Excellent in properties.

  In the partition M in this embodiment, the structural material J includes a single basic member 1 and a plurality (two) of tip members 2 provided on the basic member 1. And the structural material J which has each said front-end | tip member 2, and the said plastic hollow plate P are each connected by the connection structure mentioned above. For this reason, it is possible to realize the partition M in which the connection work is easily performed and the connection state is preferably maintained. Since the groove member P2 has the upward opening n1 and the downward opening n2, when removing the structural material J, the structural material J is slid along the groove Z in the longitudinal direction, and the upward opening n1. Or what is necessary is just to pass the downward opening part n2. Since the structural material J can be set to have a shorter vertical dimension than the groove member P2, when the structural material J is taken out of the groove member P2, the structural material J becomes an obstacle such as a ceiling. It will be difficult to interfere with.

  The plastic hollow plate P has a hollow plate main body P1 mainly composed of a plurality of bubble boards P11 stacked in a state where the positions of the bubbles are shifted from each other, and has the groove Z provided on the end edge surface of these bubble boards P11. And a single groove member P2. For this reason, the hollow plate main body P1 in which the variation in strength is suppressed as a whole can be provided.

  The present invention is not limited to the embodiment described in detail above.

  The structural material may not be for holding another plastic hollow plate. That is, the structural material may hold a functional member instead of another plastic hollow plate. For example, the base member of the structural material may hold a cover for covering the side edge of the partition. At this time, a cover may be provided directly on the basic member of the structural material, or a cover may be attached to the basic member of the structural material via the tip member. That is, the structural material may function as a bracket for attaching the functional member. Various functional members are conceivable. In addition to the above-described cover, for example, electrical products such as lighting devices and furniture components such as shelves and hooks are conceivable.

  The partition M may use two or more plastic hollow plates P. For example, as shown in FIGS. 10 to 13, by using a structural material J, a cap C, and an intermediate leg L that form a cross shape in plan view, one end of each of the four plastic hollow plates P is connected to one another. It is possible to concentrate on the places and connect to each other. The structural material J in this embodiment includes a single basic member 1 and four tip members 2 projecting from the basic member 1 in four directions. In addition, about the same figure in other embodiment, suppose that the same or corresponding structure attaches | subjects and demonstrates the code | symbol same as the thing of embodiment mentioned above, and abbreviate | omits detailed description. Even in such a case, the intended purpose can be achieved.

  Further, the structural material J can be set in various shapes other than the above-mentioned I-shaped type or cross-shaped type corresponding to the configuration of the partition M. For example, FIG. 14 shows a case where a T-shaped structural material J in which three plastic hollow plates P are connected is employed. The structural material J in this embodiment includes a single basic member 1 and three tip members 2 projecting from the basic member 1 in three directions. A structural material J shown in FIG. 15 employs a T-shaped structural material J having a shape different from that of the structural material J shown in FIG. In FIG. 16, an L-shaped structural material J is employed so that two plastic hollow plates P can be connected in a state of being orthogonal to each other. The structural material J in this embodiment includes a single basic member 1 and 23 tip members 2 that project from the basic member 1 in two directions. Even in such a case, the intended purpose can be achieved.

  The plastic hollow plate may not have a groove member. That is, the plastic hollow plate only needs to have a groove provided at the side end.

  In the case where the plastic hollow plate has a hollow plate main body and a groove member, the connection between the hollow plate main body and the groove member is not limited to welding, for example, an adhesive may be used, or plastic The main body and the groove member may be fitted together or sewn by an appropriate method.

  In addition, the specific configuration of each part is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
