Description

[Detailed description of the device]

[0001]

[Industrial applications]

 Doors, construction materials, boxes, frames, tops, construction panels, and other furniture, fittings, and building materials that are painted and manufactured after assembly are made up of multiple components. At least one of the constituent members relates to a joint structure in the combined portion when members are combined by actual fitting, interleaving, tenon fitting, and various other fitting modes.

[0002]

[Prior art and its problems]

 It has been well known that furniture, fittings, building materials, etc. in which a plurality of members are fitted together by some means to assemble and then painted on the surface to complete it have been conventionally known.

[0003] However, since both ends of the joint portion where members that compose such conventional furniture, fittings, and building materials are fitted together are abutted, a surface shape having a level surface between both members. However, when a coating is applied to the joint, the coating will be continuously formed between both members.

For this reason, the coating film is cracked due to the contraction of both members with the lapse of time, which is unsightly in appearance and significantly reduces the commercial value.

In order to solve such a problem, in Japanese Patent Laid-Open No. 59-72384, "frame members such as a frame, a frame, a band and a bundle are butted against each other to form a frame, and a panel is fitted inside the frame. In manufacturing a combined wooden door, a narrow groove is formed on all of the abutting boundary plates of the frame constituent members, and the entire surface of the door body including the narrow groove is coated. "

[0006] However, this proposal simply prevents the formation of a continuous coating film on the surface between the two members to be joined, and causes the cracking of the coating film due to the contraction of the members to occur between the members. It only occurs in the deep part of the formed narrow groove and the appearance is hard to be exposed, and when it comes into close contact, there is a difference in light and the color difference between the surface coating and the own color of the member. When it is large, it is possible to easily recognize the breakage of the coating film in the narrow groove, and it has not been a complete solution to the above problems.

Further, in such a structure in which the narrow groove is provided, the coating material is accumulated in the narrow groove after coating, and the narrow groove portion itself deteriorates the appearance.

[0008]

[Problems to be solved by the device]

 If cracks in the coating film occur at the abutting parts of furniture, building, and building material components, make these cracks inconspicuous.

[0009]

[Technical means]

 In the joining structure in which the fitting portion 6 of the fitting member 2 is fitted into the fitting portion 11 of the fitting member 1 and the abutting portion of the fitting member 1 and the fitting member 2 are separated at least on the surface via a gap 7. ,

The mouth end surface of the member 1 to be fitted is cut away leaving the surface side end portion e, and a space 8 surrounded by the fitting portion 6 and the surface side end portion e is formed.

A joint structure in which the space 8 communicates with the gap 7 to form a built-in void 9, and a coating film p is applied to the surfaces of the fitted member 1 and the fitted member 2 without filling the built-in void 9.

[0012]

[Action]

 Since the coating film p is applied without filling the built-in voids 9, even if cracks occur in the coating film p, the cracks are hidden in the built-in voids 9 and are not noticeable. Therefore, the design of the joint structure is not disturbed.

[0013]

【Example】

 Below, based on an example, it explains according to a drawing. FIG. 1 shows a frame composed of left and right vertical frames 1, 1a, upper and lower horizontal frames 2, 2a, a band 3, upper and lower bundles 4, 4a, and a wooden door in which an end plate 5 is fitted inside the frame structure. The joint portion of each member has the joint structure according to the present invention.

FIG. 2 is a perspective view showing a mutual portion of arrows aa showing a joint structure of the vertical frame 1 and the horizontal frame 2 of the door in FIG. The vertical frame 1 has a female fruit, and the male frame 6 of the horizontal frame 2 is fitted therein. That is, here, the fitted member is the vertical frame 1, the fitted member is the horizontal frame 2, the fitting portion is the male 6 of the lateral frame 2, and the fitted portion is the female 11.

As can be seen from FIG. 2, the abutting portions of the vertical frame 1 and the horizontal frame 2 are separated on the surface. This may be done by cutting at least one of the vertical frame and horizontal frame in advance so that they do not face each other during assembly, or by forming it with a router etc. after assembly, but as a result, both A gap 7 is secured as a separation part in the.

Since the joint between the vertical frame 1 which is the member to be fitted and the horizontal frame 2 which is the member to be fitted is separated on the surface in this way, even when coating is applied after assembly, both of them are still on the surface. The continuous coating film 4 is not formed between them, and the coating film p is not cracked on the surface even by the contracting movement of the member.

Further, the vertical frame 1 is provided with a space 8 continuous with the gap 7 so as to contact the surface of the male 6 of the vertical frame 1 in the direction of the abutting portion.

The space 8 is preferably formed in advance before assembling the members, but it may be removed together with the gap 7 after the assembly.

In this way, a built-in space 9 communicating with the surface is formed between the vertical frame 1 and the horizontal frame 2. On the surface of the assembled door, paint is applied to the entire surface including the built-in void 9 without filling the built-in void 9.

The coating material to be applied may be applied to the entire inside of the built-in void 9, but it is sufficient that it is applied to at least the portion of the hatched line b shown in FIG.

Since the coating material is applied in the internal space 9 as described above, cracking of the coating film due to the contraction movement of the member will appear at the portion 10. Therefore, as shown in FIG. 4, even if the coating film is cracked by the contraction movement of the member, the appearance is covered by the end e on the front surface side of the vertical frame 1 which is the fitting side member, and is exposed from the outside. Never.

Further, since the existence of the space 8 also functions as an escape area for the coating material to be applied, the coating material accumulation in the groove portion, which is inevitable in the coating after assembly, which is inevitable in the prior art, does not occur.

Therefore, the gap 7 as the separated portion to be seen can have a smart appearance, which is an important point in enhancing the surface design.

Although the joint structure between the vertical frame 1 and the horizontal frame 2 has been described above as an example, this joint structure is formed between the vertical frame 1, 1a, the horizontal frame 2a, the band 3, and the bundles 4, 4a. It goes without saying that this is done between the belt 3 and the horizontal frames 2 and 2a, and also between the frame member and the end plate constituted by these.

Further, as shown in FIGS. 5A and 5B, even when the end plate 5 having a shape without the abutting portion on the surface portion is fitted to the frame member 12, when the coating material is applied, Exactly the same effect can be obtained.

In FIGS. 5 a and 5 b, the built-in space 9 is formed by the space 8 and the gap 7. Reference numeral 10 indicates a portion where the coating film p is cracked.

Although the wooden doors have been described in the above embodiments, the joining structure according to the present invention has a joining portion which is fitted and assembled by the fitted member 1 and the fitting side member 2 and is applied after assembly. As long as it is finished, it can be used widely regardless of fitting style, joining position, furniture, fittings, and building materials.

For example, in the case of the interlocking joint structure as shown in FIG. 6a, and in the joint structure of two male and female as shown in FIG. 6b, as shown in FIG. Is also used. Reference numerals 1 and 2 denote a fitted member and a fitted member, respectively.

[0029]

[Effect of the device]

 a. Since the joints between the members are separated on the surface, a continuous coating film p is not formed between the two even when the coating is applied after assembly, and the contraction movement of the members prevents The crack of the coating film p does not occur on the surface.

B. Since the paint is applied in the space 8 formed in the receiving side member 1 as described above, cracks in the coating film p due to the contracting movement of the member are covered by the surface side end e of the receiving side member 1. Therefore, even if the coating film p is cracked by the contracting movement of the member, the appearance is not exposed from the outside.

C. The existence of the space 8 formed in the receiving side member 1 also functions as an escape area for the coating material to be applied. Since it does not occur, the surface design is not deteriorated, and it also becomes an important element for creating a superior surface design by giving a smart design property to the gap 7 as the separated portion to be observed.

Therefore, even if coating is performed after assembly, it is possible to obtain a joint portion capable of maintaining a beautiful finish in which no cracks in the coating film at the joint portion between the members are visible.
