Detailed Description

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following drawings, the same or corresponding portions are denoted by the same reference numerals, and description thereof will not be repeated.

Fig. 1 is a perspective view of a housing to which the coupling member of the present embodiment is applied. The frame construction of the frame body 100 is schematically shown in fig. 1.

Referring to fig. 1, a frame 100 is formed by coupling a plurality of frame members to each other. The plurality of frame members have a first beam member 1 extending in the horizontal direction (Y direction in the figure), a second beam member 2 extending in the horizontal direction (X direction in the figure), and a column member 3 extending in the vertical direction (Z direction in the figure). The first beam member 1, the second beam member 2, and the column member 3 correspond to one example of an "extension member" extending linearly.

The frame 100 further includes a coupling member 5 for coupling at least two or more extension members. The connecting member 5 is disposed at a corner portion of the frame 100, and connects the first beam member 1, the second beam member 2, and the column member 3.

Fig. 2 is a perspective view of the coupling member 5. Referring to fig. 2, the connecting member 5 includes a first portion 51, a second portion 52, a third portion 53, and a fin portion 54.

The first portion 51 has a planar shape, and has an inner surface 51a as one surface, and an outer surface 51b as the other surface. The first portion 51 has a first side 51c extending linearly and a second side 51d extending linearly and perpendicular to the first side 51 c.

The first portion 51 has a shape in which one vertex portion of a rectangle is cut off. The notch is formed in a rectangular shape in which one vertex portion of the rectangle is cut off. However, the shape of the notch is not limited to this.

The first portion 51 is formed with a plurality of through holes 6a and 6b penetrating the first portion 51 in the thickness direction. The inner surfaces 51a of the through holes 6a and 6b are chamfered. The number of through holes is not limited to two.

The second portion 52 has a planar shape, and has an inner surface 52a as one surface, and an outer surface 52b as the other surface. The second portion 52 is bent at the first side 51c with respect to the inner surface 51a of the first portion 51, and extends perpendicularly with respect to the inner surface 51 a.

The second portion 52 is formed with a plurality of through holes 6c and 6d penetrating the second portion 52 in the thickness direction. The inner surfaces 52a of the through holes 6c and 6d are chamfered. The number of through holes is not limited to two.

The third portion 53 has a planar shape, and has an inner surface 53a as one surface, and an outer surface 53b as the other surface. The third portion 53 is bent at the second edge 51d with respect to the inner surface 51a of the first portion 51 and extends perpendicularly with respect to the inner surface 51 a. The third portion 53 is formed with a plurality of through holes 6e and 6f penetrating the third portion 53 in the thickness direction. The inner surfaces 53a of the through holes 6e and 6f are chamfered. The number of through holes is not limited to two.

The first portion 51, the second portion 52, and the third portion 53 are arranged so as to be orthogonal to each other. The first portion 51 and the second portion 52 are joined at a first edge 51c, and the first portion 51 and the third portion 53 are joined at a second edge 51 d. A gap 55 is formed between the second portion 52 and the third portion 53.

The fin portion 54 has a planar shape, and has a first surface 54a as one surface and a second surface 54b as the other surface. The fin portion 54 is bent with respect to the inner surface 52a of the second portion 52, and protrudes perpendicularly with respect to the inner surface 52 a. The first surface 54a of the fin 54 faces the third portion 53 and is provided parallel to the third portion 53.

The fin portion 54 is formed with a through hole 6g penetrating the fin portion 54 in the thickness direction. The first surface 54a side of the through hole 6g is chamfered. The number of through holes is not limited to one.

Fig. 3 is an expanded view of the coupling member 5 shown in fig. 2.

Referring to fig. 3, the coupling member 5 is formed by drilling the plate member 10 and bending the plate member 10. As a material constituting the flat plate member 10, for example, a steel plate such as mild steel or stainless steel, an aluminum plate, or the like can be used. The thickness of the plate member 10 is, for example, about 1 to 3.5 mm.

The second portion 52 and the third portion 53 are formed by bending the flat plate member 10 at right angles to the portion where the first portion 51 is formed. Further, the fin portion 54 is formed by bending the flat plate member 10 at right angles to the second portion 52.

That is, the inner surface 10a of the flat plate member 10 constitutes the inner surface 51a of the first portion 51, the inner surface 52a of the second portion 52, the inner surface 53a of the third portion 53, and the first face 54a of the fin portion 54. The outer surface 10b of the flat plate member 10 constitutes an outer surface 51b of the first portion 51, an outer surface 52b of the second portion 52, an outer surface 53b of the third portion 53, and a second face 54b of the fin portion 54.

The first side 51c and the second side 51d are located at the curved central portion of the plate member 10. The third side 52c of the second portion 52 is located at the curved central portion of the plate member 10.

In this way, the coupling member 5 can be formed by bending the flat plate member 10, and thus workability of the coupling member 5 is improved. Further, since the connecting member 5 can be constituted by only a single member (the flat plate member 10), the connecting member can be made lighter and cheaper than a case where a plurality of members are combined to constitute a connecting member.

When a plurality of components are combined to form a connecting component, an operation for aligning the components is required, and therefore, there is a problem that an assembling operation of the housing is complicated and takes time. In contrast, since the coupling member 5 of the present embodiment does not require a positioning operation, the workability of the housing 100 can be improved.

Next, a frame 100 in which a plurality of extension members are coupled to each other using the coupling member 5 of the embodiment will be described.

Fig. 4 is an exploded perspective view of a corner portion of the frame body 100. Fig. 4 shows only the beam members 1 and 2 and a part of the column member 3 in the vicinity of the corner portion of the frame body 100.

The first beam member 1 is fixed to the first portion 51 by rivet joint using a rivet, not shown, that penetrates the through hole 6 a. The first beam member 1 is further fixed to the second portion 52 by rivet joining using a rivet, not shown, that penetrates the through hole 6 c. The through hole 6a formed in the first portion 51 and the through hole 6c formed in the second portion 52 function as rivet holes through which rivets for connecting the first beam member 1 to the connecting member 5 are passed.

The second beam member 2 is fixed to the first portion 51 by rivet joint using a rivet, not shown, that penetrates the through hole 6 b. The second beam member 2 is further fixed to the third portion 53 by rivet joining using a rivet, not shown, that penetrates the through hole 6 f. The through-hole 6b formed in the first portion 51 and the through-hole 6f formed in the third portion 53 function as rivet holes through which rivets for connecting the second beam member 2 to the connecting member 5 are passed.

The pillar member 3 is fixed to the second portion 52 by rivet joining using a rivet, not shown, that penetrates the through hole 6 d. The pillar member 3 is also fixed to the third portion 53 by rivet joining using a rivet that penetrates the through hole 6 e. The pillar member 3 is also fixed to the fin portion 54 by rivet joining using a rivet, not shown, that penetrates the through hole 6 g. The through-holes 6d formed in the second portion 52, the through-holes 6e formed in the third portion 53, and the through-holes 6g formed in the fin portion 54 function as rivet holes through which rivets for connecting the column member 3 to the connecting member 5 are passed. Since the inner surface of the pillar member 3 is rivet-joined to the second portion 52, the third portion 53, and the fin portion 54, the strength of the inner surface of the pillar member 3 can be increased. This can improve the strength of the housing 100.

In this way, the first beam member 1, the second beam member 2, and the column member 3, which are the plurality of extension members, are joined by riveting and are connected to each other via the connecting member 5, thereby forming the housing 100. Since the first beam member 1, the second beam member 2, and the column member 3 need not be connected by welding and only need to be fixed by rivets, workability of the housing 100 can be improved.

On the other hand, since the connecting member 5 is constituted only by the flat plate member 10, there is a possibility that the strength of the connecting member 5 is reduced as compared with a configuration in which a plurality of members are combined. When the strength of the connecting member 5 is reduced, the strength of the frame 100 is reduced because the strength of the connection of the plurality of extension members connected by the connecting member 5 is also reduced. Further, the strength of the connecting member 5 can be increased by increasing the thickness of the flat plate member 10, but the connecting member 5 is increased in weight, resulting in an increase in weight of the housing 100.

Therefore, the coupling member 5 of the present embodiment improves the bonding strength between the coupling member 5 and the extension member by adjusting the bending radius of the flat plate member 10 during the bending process. This makes it possible to disperse the load applied to the connecting member 5 to the extension member, and therefore, the strength of the connecting member 5 can be enhanced.

Fig. 5 is a view seen from the direction of arrow a shown in fig. 4. In fig. 5, only the first portion 51 and the third portion 53 of the connecting member 5 and a part of the second beam member 2 are illustrated.

As described above, the third portion 53 is formed by bending the plate member 10 at right angles to the inner surface 51a of the first portion 51.

The second beam member 2 is disposed such that the inner surface 2a of the second beam member 2 is in surface contact with the outer surface 51b of the first portion 51 and the outer surface 53b of the third portion 53. The second edge 51d of the first portion 51 is located at the curved central portion. In fig. 4, the radius of curvature of the outer surface 51b at the second side 51d is set to R. The bending radius R corresponds to the radius of a circle C that describes a curve of the same size as the curved central portion of the outer surface 51 b. The bending radius R is made equal to the bending radius of the inner surface 2a of the second beam member 2. In the present specification, the term "equal radius of curvature" means that the radii of curvature are substantially equal, and includes the case where the radii of curvature are approximately equal to the extent that surface contact can be ensured. By equal bend radii, for example, deviations corresponding to bend radii within ± 10% of a value.

In this way, the contact between the first portion 51 and the second beam member 2 can be improved even in the second edge 51d portion, and therefore the joining strength between the connecting member 5 and the second beam member 2 can be improved.

In fig. 5, when the thickness of the first portion 51 and the third portion 53 is d1 and the thickness of the second beam member 2 is d2, the connecting member 5 is lightened when the thickness d1 is reduced, while the strength of the first portion 51 and the third portion 53 is reduced. By increasing the bonding strength between the first portion 51 and the third portion 53 and the second beam member 2, the first portion 51 and the third portion 53 can be reinforced by the second beam member 2. The first portion 51 and the third portion 53 can be regarded as having a thickness corresponding to the sum of the thicknesses d1 and d 2. Thus, even if the thickness d1 of the first portion 51 and the third portion 53 is reduced, the strength of the first portion 51 and the third portion 53 can be ensured.

Returning to fig. 4, in the coupling member 5, the joining strength between the coupling member 5 and the first beam member 1 can be improved by making the radius of curvature of the outer surface 51b at the first edge 51c equal to the radius of curvature of the inner surface 1a of the first beam member 1.

In the fin portion 54, the bending radius of the outer surface 52b of the second portion 52 is equal to the bending radius of the inner surface 3a of the column member 3, whereby the joining strength between the connecting member 5 and the column member 3 can be improved. As a result, even if the thickness of the connecting member 5 is reduced, the connection strength of the plurality of extension members connected by the connecting member 5 can be increased, and the strength of the housing 100 can be increased. That is, the weight of the connecting member 5 can be reduced while the strength of the connecting member 5 is ensured.

The embodiments disclosed herein are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is indicated by the claims rather than the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are intended to be embraced therein.
