The connecting device 100 is used, for example, when a plurality of sheets in an assembled furniture are combined and connected to each other. The male member 1 and the female member 6 are formed of, for example, a synthetic resin.  

(male component)  The male member 1 is a male member that is inserted into the female member 6 and connected to the female member 6. As shown in FIG. 1 , the male member 1 is a cylindrical member that is inserted into the housing hole 61 of the female member 6 described later and integrated with the female member 6 . The male member 1 has a shaft portion 11 and a columnar portion 16. Further, an intermediate portion 10 is provided between the shaft portion 11 and the columnar portion 16.  

The shaft portion 11 is a portion that is actually inserted into the housing hole 61 of the female member 6, and has a cylindrical portion 12, a tapered portion 13, and a distal end portion 14. The cylindrical portion 12 is a cylindrical portion that is inserted into the housing hole 61 of the female member 6 and engaged with the female member 6. The outer peripheral surface in the vicinity of the taper portion 13 of the cylindrical portion 12 has concave portions 12a, 12b, and 12c (hereinafter referred to as "recess portions 12a to 12c") which are recessed in the radial direction on the inner side in the radial direction. In addition, although three recesses 12a to 12c are formed in the present embodiment, the number of recesses is not limited thereto.

The recesses 12a to 12c are formed so as to be annular in the entire circumference of the cylindrical portion 12 around the axis x1, and are disposed apart from each other at a predetermined interval in the direction of the axis x1. The cylindrical portion 12 has a predetermined outer diameter OD1 at a portion other than the recesses 12a to 12c, and has an outer diameter OD2 (OD2 < OD1) smaller than the outer diameter OD1 at the recesses 12a to 12c.

The tapered portion 13 is formed to be tapered from the cylindrical portion 12 toward the distal end, and the outer peripheral surface is inclined toward the distal end portion 14 along the axis x1, and has a substantially trapezoidal shape in a side view. The outer diameter of the tapered portion 13 is continuously reduced toward the front end portion 14 as compared with the outer diameter OD1 of the cylindrical portion 12.

The distal end portion 14 is connected to the tapered portion 13 to be formed in a cylindrical shape. The front end portion 14 has a slit 14a extending from the front end toward the proximal end side (intermediate portion 10) of the male member 1 along the axis x1. The slit 14a extends to the tapered portion 13 so as to include the axis x1. Further, as shown in FIG. 2(a), the slit 14a extends in the radial direction by the axis x1.

The columnar portion 16 is, for example, a cylindrical portion that is embedded in the sheet material in the assembled furniture. The columnar portion 16 is connected to the intermediate portion 10 and has a plurality of projecting pieces 17 having a triangular cross section along the axis x1 on the outer peripheral surface. A pair of (two) projecting pieces 17 are provided on the same plane orthogonal to the axis x1, and as shown in FIG. 2(b), each of the projecting pieces 17 is formed in an arc shape on the outer peripheral surface of the columnar portion 16. The pair of protruding pieces 17 are disconnected in the circumferential direction at any position on the outer peripheral surface of the columnar portion 16. In other words, two passages 18 along the axis x1 are formed between the protruding pieces 17 in the circumferential direction. Further, the protruding piece 17 is not limited as long as it is not annular, and the number is not limited.

Each of the projecting pieces 17 has an inclined surface 17a which is formed obliquely so as to approach the axis x1 toward the front end side of the columnar portion 16 (the proximal end side of the male member 1) at a predetermined angle with respect to the axis x1, and is formed at a vertical angle with respect to the axis x1. Vertical face 17b.

(mother type member)  As shown in Figure 1 and Figure 3. The female member 6 is a female member having a cylindrical shape including a housing hole (accommodating portion) 61 and housing the male member 1 . The female member 6 is a projection piece 62 having a plurality of triangular cross-sections along the axis x2 on the outer peripheral surface. A pair of (two) projecting pieces 62 are provided on the same plane orthogonal to the axis x2, and each of the projecting pieces 62 is formed in an arc shape on the outer peripheral surface of the female member 6. The pair of protruding pieces 62 are disconnected in the circumferential direction at any position on the outer peripheral surface of the female member 6. In other words, a passage 63 along the axis x2 is formed between the protruding pieces 62 in the circumferential direction. Further, the protruding piece 62 is not limited as long as it is not annular, and the number is not limited.  

Each of the projecting pieces 62 has an inclined surface 62a which is formed obliquely so as to approach the axis x2 toward the bottom portion 6A of the female member 6 at a predetermined angle with respect to the axis x2, and a vertical surface 62b formed at a vertical angle with respect to the axis x2.

The housing hole 61 of the female member 6 that houses the shaft portion 11 of the male member 1 is concentric with the axis x2, and is formed as a blind hole by the presence of the bottom portion 6a. The female member 6 has convex portions 63a to 63c that are engaged with the concave portions 12a to 12c of the male member 1 on the inner circumferential surface 64 of the housing hole 61. The convex portions 63a to 63c are formed to expand in an arc shape at the inner end in the radial direction of the cross section along the axis x2. The convex portions 63a to 63c are formed in an annular shape across the entire circumference around the axis x2 and are disposed apart from each other at a predetermined interval along the axis x2. The interval between the convex portions 63a to 63c is the same as the interval between the concave portions 12a to 12c of the cylindrical portion 12.

The accommodating hole 61 has an inner diameter ID1 (OD1 < ID1) which is only slightly larger than the outer diameter OD1 of the cylindrical portion 12 in a portion where the convex portions 63a to 63c are not present. The convex portions 63a to 63c are formed by the inner diameter ID2 which is smaller than the inner diameter ID1 of the accommodation hole 61 (ID2 < ID1). The inner diameter ID2 of the convex portions 63a to 63c is almost the same as or smaller than the outer diameter OD2 of the concave portions 12a to 12c of the shaft portion 11 (ID2 ≦ OD2). However, it is not limited thereto, and the inner diameter ID2 of the convex portions 63a to 63c is almost the same as or smaller than the outer diameter OD2 of the concave portions 12a to 12c (ID2 ≧ OD2).

A cylindrical protruding pin (projecting portion) 65 projecting from the bottom portion 6a of the female member 6 toward the insertion opening 61a side is integrally formed with the bottom portion 6a. The protruding pin 65 as a projection has a cylindrical portion 65a having a fixed diameter, and a tapered portion 65b whose diameter gradually decreases from the front end side of the cylindrical portion 65a.

Although the protruding pin 65 has a length that reaches the left and right of the tapered portion 13 in the slit 14a, it is formed shorter than the depth of the slit 14a. However, the present invention is not limited thereto, and the length of the protruding pin 65 can be arbitrarily changed in accordance with the depth of the slit 14a. The diameter d of the cylindrical portion 65a of the protruding pin 65 is the same as or slightly larger than the width w of the slit 14a (w≦d).

<Application example of connecting device>  Next, a specific example in which the connecting device 100 of the first embodiment is applied to the assembly structure 300 will be described with reference to FIGS. 4 and 5. Fig. 4 is a schematic view showing a part of the assembly structure with the connecting device of the first embodiment. 5 is a view for explaining the connection operation with respect to the connecting device of the first embodiment, and FIG. 5(a) is a partial cross-sectional view showing a state before the assembly constituent member 310 and the assembly constituent member 320 are connected, and FIG. (b) is a partial cross-sectional view showing a connected state of the assembled component member 310 and the other assembled component member 320.  

For example, when the assembly structure 300 is a cabinet as an assembly type furniture, as shown in FIG. 4, a plurality of sheets (assembly components) are assembled and connected to each other, thereby performing the operation.

Specifically, the assembly structure 300 includes a top plate (not shown), a bottom plate 310, a back plate 320, a side plate 330, and a cabinet plate (not shown). Hereinafter, the connection between the bottom plate 310 of the connecting device 100 and the side plate 330 will be described as an example. In addition, the connection procedure demonstrated below does not necessarily correspond with the assembly order of the actual assembly structure 300.

Here, in the portion abutting the side plate 330 of the bottom plate 310, the columnar portion 16 of the male member 1 is previously embedded (inserted) together with the intermediate portion 10, and the shaft portion 11 is exposed. Further, in the bottom plate 310, the female member 6 is embedded in advance. Further, even if the intermediate portion 10 of the male member 1 is not embedded in the side plate 330, it may be housed in the housing hole 61 of the female member 6.

The inclined surface 17a of the protruding piece 17 of the columnar portion 16 is formed such that the insertion direction of the conventional side plate 330 is close to the axis x1. Therefore, the male member 1 can be easily inserted into the side plate 330. Further, by the presence of the vertical surface 17b of the columnar portion 16, the vertical surface 17b acts as a resistance, so that the male member 1 cannot be easily pulled out from the side plate 330.

The side panel 330 is incorporated into the bottom plate 310 to which the female member 6 is attached. Specifically, the shaft portion 11 of the male member 1 is inserted into the housing hole 61 of the female member 6 . Thereby, the concave portions 12a to 12c in the shaft portion 11 of the male member 1 are engaged with the convex portions 63a to 63c in the accommodation holes 61 of the female member 6, respectively. At this time, the outer diameter OD2 of the concave portions 12a to 12c and the inner diameter ID2 of the convex portions 63a to 63c are almost the same size, and the convex portions 63a to 63c and the concave portions 12a to 12c are in surface contact with each other.

The connecting device 100 forms convex portions 63a to 63c on the side of the female member 6 embedded in the bottom plate 310, for example, and the male members 1 on the insertion side form the concave portions 12a to 12c. Since the entire mother member 6 is buried in the bottom plate 310 and integrated with the bottom plate 310, the quality of the bottom plate 310 can be regarded as its own quality. The shaft portion 11 of the male member 1 enters the housing hole 61 of the female member 6. The convex portions 63a to 63c of the female member 6 having a large mass body as compared with the shaft portion 11 are in a manner of holding the male member 1 across the entire circumference and entering the concave portions 12a to 12c of the male member 1 to make. The female member 6 is complementary to the mass of the bottom plate 310 and is more strongly connected to the male member 1.

According to this configuration, it can be understood that the connection strength in the connecting tool 100 is stronger than that in the connecting member in which the male member 1 forms the convex portion and the female member forms the concave portion. Further, in this case, for example, as shown in FIG. 5, the arrangement of the female member 6 to the lower side of the male member 1 is remarkable.

The protruding pin 65 of the female member 6 enters the slit 14a in the front end portion 14 of the male member 1 while the recesses 12a to 12c and the convex portions 63a to 63c are engaged. Since the protruding pin 65 is provided on the axis x1 of the female member 6, the centering of the male member 1 in the female member 6 is performed. Thereby, the concave portions 12a to 12c and the convex portions 63a to 63c are uniformly engaged in the respective entire circumferences. Further, since the width w of the slit 14a is smaller than the diameter d of the cylindrical portion 65a of the protruding pin 65, an interference fit is formed between the slit 14a and the protruding pin 65.

The columnar portion 16 is inserted into a hole (not shown) formed at a corresponding position of the side plate 330, and an adhesive or the like is injected into the hole. Since the columnar portion 16 of the male member 1 has a plurality of pairs of protruding pieces 17 which are broken by the passage 18 along the axis x1, when the side plate 330 is inserted, the adhesive flows through the passage 18 along the axis x1. Between each of the protruding pieces 17 is juxtaposed. In this way, the columnar portion 16 of the male member 1 is strongly attached to the side plate 330.

Further, since the contours of the concave portions 12a to 12c and the convex portions 63a to 63c are arc-shaped with each other, a sufficient engaging force due to the surface contact is exhibited by the concave-convex engagement, and the engagement is released when the engagement is released. The manner of destruction allows the recesses 12a to 12c and the projections 63a to 63c to be easily separated.

As long as the assembly is connected to at least two assembly members, it is not limited to cabinets, drawers, dressing tables, sideboards, bookcases, tables, chairs, long tables, beds, boxes, TV cabinets, audio racks, and speaker cabinets. Other various assembly components such as a computer stand can also be used.

<Other>  In addition, the connection device 100 is not limited to the above-described embodiment, and can be appropriately changed within a range not exceeding the scope of the present invention. For example, as long as the desired joint strength can be obtained by the engagement between the concave portions 12a to 12c and the convex portions 63a to 63c, the slit 14a in the male member 1 and the protruding pin 65 in the female member 6 are not essential. Essentials.  

Further, a modification 1 of the male member 1 will be described with reference to Fig. 6 . As shown in FIG. 6, the male member may be a male member 1A in which the protruding piece 17 of the columnar portion 16 in the connecting device 100 is a plurality of protrusions 27 that are irregularly disposed on the circumferential direction. Thereby, individual protrusions 27 are formed. The projection 27 has an inclined surface 27a which is formed obliquely so as to approach the axis x1 toward the front end side of the columnar portion 16, and a vertical surface 27b which is formed at a vertical angle with respect to the axis x1.

Further, each of the projections 27 has a slightly triangular pyramid shape, but the shape of the projections 27 is not limited thereto, and may have a shape such as a slight pyramid or a slightly conical shape.

Further, a second modification of the male member 1 will be described with reference to FIG. As shown in FIG. 7, the male member may be a male member 1B having a head portion 19 integrally formed at the base end portion (the end portion on the opposite side to the distal end portion 14) of the shaft portion 11 instead of the columnar portion 16. The head portion 19 has a curved portion 19a formed in a concave shape on the outer surface passing through the axis x1 and not facing the shaft portion 11.

As shown in FIG. 4, the connecting tool 100 having the male member 1B is used, for example, when the backing plate 320 is fixed to the top plate, the bottom plate 310, and the side plate 330. Specifically, an insertion hole (not shown) formed in the back plate 320 is integrated into the top plate, the bottom plate 310, and the female member 6 attached to the side plate 330 to insert the male member 1B into the insertion hole and the female member. The storage hole 61 of 6. Since the male member 1B has the curved portion 19a in the head portion 19, the finger of the worker becomes easy to come into contact with the female member 6, and the load on the finger during the connection work is reduced and the workability is improved.

Further, the cross-sectional shape of the male member 1, the male member 1A, and the male member 1B is not limited to a circular shape, and a polygonal shape such as a triangle, a quadrangle, or a pentagon may be used. In this case, the housing hole 61 of the female member 6 is formed to have a contour corresponding to the cross-sectional shape of the male member 1, the male member 1A, and the male member 1B.

<Second embodiment>  Next, the connection tool 100C relating to the second embodiment will be described with reference to FIG. In the following, only the portions different from the configuration of the connecting device 100 of the first embodiment will be described, and the same configurations as those of the first embodiment will be denoted by the same reference numerals and will not be described. Fig. 8 is a view for explaining the configuration of the connecting tool 100C of the second embodiment. Fig. 8(a) is a cross-sectional view of the connector 100C, and Fig. 8(b) is a plan view of the connector 100C.  

The connector 100C includes a composite male member 1C integrally formed of two male members 1 and a male member 1, and two housing holes 61 and housing holes 61 for accommodating the shaft portions 11 of the male member 1C. Female member 6C. In addition, since each of the male members 1 constituting the male member 1C has almost the same configuration as the male member 1 in the first embodiment, the description will be omitted, only for the female member in the first embodiment. The mother member 6C will be described with a different configuration.

The male member 1C is integrally formed by being disposed at predetermined intervals while the respective axes x1 of the respective male members 1 are parallel to each other. Specifically, the male member 1 and the male member 1 are integrally provided with the intermediate portion 10C. The intermediate portion 10C has a slightly elliptical shape in a plan view.

The female member 6C has a slightly elliptical shape in a plan view. The female member 6C has two housing holes 61 and housing holes 61, and has two jaw portions 66C in the direction in which the housing holes 61 are arranged side by side. The crotch portion 66C has a hole 66Ca through which the screw (not shown) or the like is inserted when the female member 6C is embedded in the assembled component member 310 or the like.

The center of the female member 6C is formed with a recess having the same shape as that of the intermediate portion 10C of the male member 1C and in which the intermediate portion 10C is fitted. The female member 6C has a plurality of triangular projection pieces 62 along the axis x2 on the outer peripheral surface of the lower portion of the crotch portion 66C.

Since the connecting device 100C includes a composite male member 1C having two male members 1 and a male member 1, and a female member 6C connected to the composite male member 1C, at least the first member The connecting device 100 of the embodiment has the same function and effect, and at the same time, can achieve a higher connection strength than the connecting device 100.

<Other>  In addition, the connection tool 100C is not limited to the above-described embodiment, and can be appropriately changed within a range not exceeding the scope of the present invention. For example, as long as the desired connection strength can be obtained by the engagement of the concave portions 12a to 12c and the convex portions 63a to 63c, the slit 14a in the male member 1C and the protruding pin 65 in the female member 6C are not essential constituent elements. .
