The best mode for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view showing an assembly-type closet assembled using the connecting device according to the present invention, and FIG. 2 is an exploded perspective view thereof. As shown in these drawings, the closet 1 has a lower plate 2, left and right side plates 3, 4, a back plate 5, a top plate 6 and a shelf plate 7 as building materials constituting the same.

  The lower plate 2 is horizontally disposed with its longitudinal direction facing the left-right direction. Side plates 3 and 4 and a back plate 5 are erected on the left and right ends and the back end of the upper surface of the lower plate 2, respectively. The lower plate 2, the side plates 3, 4 and the back plate 5 are connected and fixed by the connecting device 10 according to the present invention. The end portions on the back side of the side plates 3 and 4 and the left and right end portions of the back plate 5 are connected and fixed by a connecting device 10. A top plate 6 is inserted into the upper end of the space on the plan view “U” defined by the side plates 3, 4 and the back plate 5. The top plate 6 is arranged in parallel with the lower plate 2, that is, horizontally. The left and right ends of the top plate 6 are connected to the upper ends of the side plates 3 and 4 by a connecting device 10. The back end of the top plate 6 is connected and fixed to the upper end of the back plate 5 by the connecting device 10. A shelf plate 7 is inserted in an intermediate portion of the “U” -shaped space in plan view defined by the side plates 3 and 4 and the back plate 5. The shelf board 7 is arranged horizontally. Both left and right end portions of the shelf plate 7 are connected and fixed to a middle portion in the vertical direction of the side plates 3 and 4 by a connecting device 10. The end on the back side of the shelf board 7 is connected and fixed to the intermediate part in the vertical direction of the back board 6 by the connecting device 10.

  As shown in FIGS. 3 to 5, the coupling device 10 includes a female member 20 and a male member 30. The female member 20 and the male member 30 are made of a hard material, and are configured as follows, for example, by molding a hard resin.

  As shown in FIGS. 3 to 5 and FIGS. 6 to 8, the female member 20 has a substantially rectangular parallelepiped shape, and penetrates up to the back surface 20 c at both ends in the longitudinal direction of the front surface (first outer surface) 20 a. A screw insertion hole 21 is formed. The female member 20 is fixed to the side plate 3 by screwing a screw (not shown) inserted through the screw insertion hole 21 into the side plate 3, for example. An engaging recess 22 is formed at the center of the front surface 20a of the female member 20 in the longitudinal direction. The engaging recess 22 is arranged with its longitudinal direction coinciding with the longitudinal direction of the female member 20. One side portion of the engaging recess 22 in the short direction is open to the outside from a lower surface (second outer surface) 20b orthogonal to the front surface 20a. Both end surfaces 22a and 22b in the longitudinal direction of the engagement recess 22 are inclined in opposite directions so as to approach each other from the upper side (upper side in FIGS. 3 and 6) of the engagement recess 22 toward the lower surface 20b. ing. As a result, the engagement recess 22 has a trapezoidal shape in plan view, and the length of the engagement recess 22 gradually decreases from the inner side toward the lower surface 2b side.

  As shown in FIGS. 3 to 5 and FIGS. 9 to 13, the male member 30 has an engaging portion 31 and a protrusion 32. A screw insertion hole 33 is formed in the central portion of the engaging portion 31 in the longitudinal direction of the front surface 31a. The screw insertion hole 33 penetrates the engaging portion 31 and the protrusion 32 formed integrally with the back surface 31b of the engaging portion 31 in the front-rear direction. Then, a screw (not shown) inserted through the screw insertion hole 33 is screwed into the lower plate 2 and tightened, for example, so that the male member 30 has its back surface 31b pressed against the upper surface of the lower plate 2. It is fixed with.

  The engaging portion 31 has a trapezoidal shape in plan view, and both end surfaces 31c and 31d in the longitudinal direction are inclined in opposite directions so as to approach each other from the front surface 31a side to the back surface 31b side. . The inclination angles of the both end faces 31 c and 31 d are set to be the same as the inclination angles of the both end faces 22 a and 22 b of the engaging recess 22. In addition, the interval between the two end surfaces 31c and 31d is set to be substantially the same as the corresponding interval between the two end surfaces 22a and 22b of the engaging recess 22. Therefore, the engaging portion 31 can be inserted into and removed from the engaging recess 22 in the front-rear direction from the front opening, and the back surface 31b of the engaging portion 31 is placed on the lower surface of the female member 20 as shown in FIGS. When the engaging portion 31 is inserted into the engaging recess 22 in a state where it is positioned on the same plane as 20b, the end surfaces 31c and 31d are in surface contact with the end surfaces 22a and 22b with almost no gap. As a result, the engaging portion 31 engages with the engaging recess 22 so as not to escape downward.

  A slit 34 extending from the front surface 31a to the back surface 31b is formed on one end surface 31c in the longitudinal direction of the engaging portion 31. The slit 34 includes a horizontal portion 34a that extends horizontally from the end surface 31c toward the inside of the engaging portion 31, and a vertical portion 34b that extends downward from the inner end portion of the horizontal portion 34a. The substantial portion 35 existing between the lower end portion of the vertical portion 34b and the lower surface of the engaging portion 31 (the side surface facing the front in the insertion direction of the engaging portion 31 into the engaging recess 22) 31e can be elastically deformed. It is thin to the extent.

A portion surrounded by the slit 34 and the substantial portion 35 is a contact portion 36. One side surface 36 a of the contact portion 36 is formed in parallel with the side surface 31 c of the engagement portion 31. Moreover, the one side surface 36a is projected outward from the side surface 31c by a predetermined minute distance, for example, 0.1 to 02 mm. The one side surface 36a can be displaced toward the inside of the engaging portion 31 by elastically deforming the substantial portion 35 so that the width of the vertical portion 34b of the slit 34 becomes narrow. Therefore, the abutting portion 36 can be inserted into and removed from the engaging recess 22 together with other portions of the engaging portion 31, and the back surface 31 b of the engaging portion 31 is located on the same plane as the lower surface 20 b of the female member 20. When the engaging portion 31 is inserted into the engaging recess 22 in this state, one side surface 36a of the contact portion 36 is pressed against the end surface 22a by the elastic restoring force of the substantial portion 35, and the end surface 22b by the reaction force. , 31d are brought into press contact with each other. Thereby, the female member 20 and the male member 30 are connected with a predetermined force without play. In addition, in a state where the engagement portion 31 is inserted into the engagement recess 22, the contact portion 36 due to the elastic restoring force of the substantial portion 35 and the force acting between the side surface 31 d and the end surfaces 22 a and 22 b cause the female The member 20 and the male member 30 are biased so as to approach each other in the vertical direction. That is, the female member 20 is urged downward in FIGS. 3 and 4, and the male member 30 is urged upward. Note that the slit 34 and the contact portion 36 may be formed at the other end portion of the engaging portion 31 or at both end portions.

  An inclined surface 37 is formed on the lower surface 31 e of the engaging portion 31. The inclined surface 37 extends from a position separated from the front surface 31a by a predetermined distance to the back surface 31b, and is inclined so as to approach the top surface 31f from the front surface 31a side toward the back surface 31b side. When such an inclined surface 37 is formed, the entire lower end portion of the engaging portion 31 is simultaneously inserted into the engaging concave portion 22 when the engaging portion 31 is inserted into the engaging concave portion 22 from the lower surface 31e side. In other words, the insertion portion of the engagement portion 31 with respect to the engagement recess 22 gradually increases from the front surface 31a side toward the back surface 31b. Therefore, the engaging portion 31 can be easily inserted into the engaging recess 22.

Further, an R chamfer 38 having an arcuate cross section is formed at each intersection between the inclined surface 37 of the engaging portion 31 and the one side surface 36a and the end surface 31d. The R chamfer 38 abuts at a position adjacent to the engagement recess 22 on the front surface 20 a when the engagement portion 31 is inserted into the engagement recess 22. Here, portions of the R chamfer 38 that abut against the front surface 20a are inclined in opposite directions so as to be separated from each other as it goes upward. Therefore, when the engaging portion 31 is inserted into the engaging concave portion 22, the portion having a short length of the engaging portion 31 is gradually inserted into the engaging concave portion 22, and the abutting portion 36 is engaged with the engaging portion 31. The pressure is displaced toward the inside. Therefore, the engaging portion 31 can be more easily inserted into the engaging recess 22. Instead of the R chamfer 38, a flat chamfer may be formed at each intersection of the inclined surface 37 (lower surface 31e), the one side surface 36a (end surface 31c) and the end surface 31d.

An example of assembling the closet 1 with the coupling device 10 having the female member 20 and the male member 30 having the above-described configuration will be described with reference to FIG. 1 to FIG. 5 at the left end portion of the upper surface (butting surface) of the lower plate 2.
