Yes.

JP-A-9-72166

  However, in the conventional door, since the panel material is bonded in a state of being fitted in the groove portion of the frame material, the panels having different linear expansion coefficients from each other in a state where the frame material is fixed or supported on the building frame or the frame body When materials and brazing materials expand or contract (or expand or contract) due to temperature changes, there is a difference in the amount of expansion and contraction, causing both members to bend, or the adhesive to break and the adhesive strength to decrease There is a problem.

  The objective of this invention is providing the fitting which can prevent the bending of the member by the temperature change etc. in the shoji which adhered the face material to the eaves, and can ensure adhesive strength.

  The joinery of the present invention is a joinery provided with a frame and a shoji supported by the frame, and the shoji includes an upper eave, a lower eave, left and right vertical eaves, and each of these eaves A face material bonded to one side surface, and a secondary saddle material attached along at least one of the vertical saddle members, and the face material and each of the saddle materials, Bonded after performing discharge treatment on each bonding surface, and at least the vertical end surface of the four circumferential end surfaces of the face material, and the prospective surface of each brazing material or the auxiliary brazing material facing this end surface A gap having a predetermined dimension is provided between the surface and each of the saddle members or the auxiliary saddle member, and a cover portion that covers a side of the gap is provided.

According to such a configuration, a predetermined dimension set based on the amount of expansion or contraction of the face material or the brazing material due to a temperature change or the like between the vertical end surface of the face material and the prospective surface of each of the brazing material or the secondary brazing material By providing the clearance (clearance), it is possible to absorb the expansion / contraction by the clearance dimension even if the face material or the eaves material expands / contracts. Therefore, a shoji formed by combining a metal frame material such as an aluminum shape and a resin surface material such as polycarbonate is used in a place with a large temperature change such as a bathroom doorway or a window. However, it is possible to prevent the face material and the saddle material from being bent.
And by providing the cover part which covers the side of a gap | interval in a saddle member or a supplementary saddle member, since a gap | interval becomes invisible on the external appearance (interior view) of a shoji, the design property can be made favorable.

In addition, since the discharge treatment is applied to the face material and the adhesive surface of each brazing material, the adhesive strength between the face material and the brazing material can be increased, and mold, bacteria, etc. attached to the adhesive surface before adhesion Can be sterilized. And the adhesive surface can be sterilized to reduce germs mixed in the shoji just after manufacture, and even when used for doorways and windows in humid bathrooms, Can be suppressed. Here, as the discharge treatment, a treatment method for modifying the surface of the material to be treated by discharge, such as plasma discharge treatment or corona discharge treatment in atmospheric pressure or vacuum, can be employed.
In addition, by fixing the face material to the saddle material by bonding, the assembly process of the shoji can be simplified and the in-plane rigidity of the shoji is dramatically improved compared to the case where it is assembled by screwing. Thus, rattling during opening and closing can be prevented.

In this case, in the joinery of the present invention, it is preferable that the face material and each of the saddle members are bonded with an indeterminate adhesive material whose viscosity varies with a temperature change.
According to such a configuration, by adhering the face material and the brazing material with an irregular-shaped adhesive material, scraps are not generated and discarded as in the case of using a regular material such as an adhesive tape or an adhesive sheet. The material used can be greatly reduced. In addition, using an indeterminate adhesive material whose viscosity fluctuates due to temperature changes, and providing the gaps (clearances) as described above, even if expansion and contraction occurs due to temperature changes in the face material and the brazing material, Since the difference in the amount can be absorbed by the deformation (shear deformation) of the adhesive material, the face material and the saddle material do not restrain each other's expansion and contraction, and these deflections can be prevented.

Further, in the joinery of the present invention, the gap includes the upper and left and right three end faces of the four peripheral end faces of the face member, and the prospective faces of the respective saddle members facing the three end faces or the auxiliary saddle members. It is preferable that it is provided between the prospective surfaces.
According to such a structure, the clearance (clearance) is provided in three directions of the face material, so that the expansion and contraction in the in-plane direction (left and right and up and down) of the face material can be reliably absorbed by these gaps. it can.

Furthermore, in the joinery according to the present invention, it is preferable that the auxiliary bridging member is attached to the upper and left three brazing members among the respective bridging members, and the cover part is provided on these auxiliary bridging members. .
According to such a configuration, by providing the cover portion on the auxiliary brazing material attached to the upper and left and right three side brazing materials, if the auxiliary brazing material is attached after the face material is bonded to the brazing material, Since the assembling operation of the shoji can be performed without the cover portion being in the way, workability can be improved.

Moreover, in the joinery of this invention, it is preferable that the auxiliary | assistant material is provided with the functional component which adds a predetermined function to the said shoji.
Here, as a functional part, a door wheel part for adding a function for guiding the shoji to be able to slide open / close with respect to the frame and a function for guiding the shoji to be able to open / close with respect to the frame are added. Closes gaps between hinge parts, handle parts that add a function to open and close the shoji, lock parts and latch parts that add a function to engage the shoji with the frame and lock it, and the frame and the shoji Examples thereof include air-tight parts that add water-stopping and air-tightness, and ventilation parts that add air permeability by communicating one and the other spaces partitioned by a shoji.
According to such a configuration, by providing the above-mentioned functional parts, which are usually provided on the saddle material, on the secondary saddle material, the size (expected dimension and finding size) of the saddle material can be reduced. The appearance design can be further improved. Even if the size of the saddle material is thus reduced, by forming the shoji by adhering the face material, the in-plane rigidity of the shoji is enhanced as described above, so that the product performance can be ensured. Furthermore, it is not necessary to provide a secondary saddle material provided with functional parts on all four sides of the shoji, and various functions can be added while maintaining the appearance design of the shoji.

Moreover, the joinery of this invention is a joinery used for a bathroom doorway, Comprising: It is preferable that the said face material is adhere | attached on the side surface by the side of the bathroom in each said rib material.
According to such a configuration, in the bathroom where the temperature change is large and the humidity is high as described above, the bending of each member of the shoji can be prevented and the occurrence of mold or the like can be suppressed. And by adhering the face material to the side of the bathroom side of each tile, the interior of the bathroom is not conspicuous and a good design can be obtained, and the bathroom side of the shoji is flat Therefore, since the level difference is reduced, it is difficult for dust and water to accumulate, and generation of mold and the like can be suppressed.

According to this embodiment, there are the following effects.
(1) That is, a clearance S1 is provided between the upper end surface of the panel material 24 and the expected surface portion 212 of the upper collar 21, and a clearance S2 is provided between the side end surface of the panel material 24 and the expected surface portion 261 of the vertical attachment 26. As a result, even if the panel material 24 and the upper, lower, left and right collars 21, 22, and 23 expand and contract, the expansion and contraction can be absorbed. Therefore, even when the shoji 20 formed by combining the aluminum shaped frame materials 21, 22, 23 and the resin panel material 24 is used at the entrance / exit of a bathroom having a large temperature change, the panel material 24 and the frame material are used. The bending of 21, 22, and 23 can be prevented.

If the vertical attachment 26 is attached, the assembling work of the shoji 20 can be performed without the extension pieces 251 and 262 getting in the way, so that workability can be improved.

(3) Since the plasma discharge treatment is applied to the bonding surfaces of the panel material 24 and the upper, lower, left and right ribs 21, 22, and 23, the bonding strength between the panel material 24 and the ribs 21, 22, and 23 is increased. In addition to being able to increase, it is possible to sterilize mold, bacteria, and the like attached to the adhesion surface before adhesion. And since the adhesive surface is sterilized, the germs mixed in the shoji 20 immediately after manufacture can be reduced, and even if it is used at the entrance / exit of a humid bathroom, generation | occurrence | production of mold | fungi etc. can be suppressed.

(4) Also, by fixing the panel member 24 to the upper, lower, left and right frame members 21, 22, and 23 by bonding, the assembly process of the shoji 20 can be simplified as compared with the case where the panel member 24 is assembled by screwing. In addition, the in-plane rigidity of the shoji 20 can be dramatically improved to prevent rattling during opening and closing. And, from the inside view from inside the bathroom, the shovels 21, 22, and 23 of the shoji 20 are not conspicuous and a good design is obtained, and the bathroom side surface of the shoji 20 is formed flat and the steps are reduced. It becomes difficult for water to accumulate, and generation of mold and the like can be further suppressed.

(5) Further, by bonding the panel material 24 and the upper, lower, left and right ribs 21, 22, and 23 with the irregular-shaped adhesive material 28, the end material is reduced as in the case of using a fixed material such as an adhesive tape or an adhesive sheet. It does not occur and the material discarded can be greatly reduced. And, while using the irregular-shaped adhesive 28 whose viscosity varies with the temperature change, and the gaps S1 and S2 are provided at the end face positions of the panel material 24, the panel material 24 and the collar materials 21, 22, and 23 are heated. Even when expansion and contraction due to change occurs, the difference in expansion and contraction can be absorbed by the shear deformation of the amorphous adhesive material 28, so that the panel material 24 and the bracing materials 21, 22, and 23 are mutually restrained. Therefore, it is possible to reliably prevent the panel material 24 and the collars 21, 22, and 23 from being bent.

(6) Further, by attaching the upper door 30, the lower door 31, the upper latch 32, and the lower latch 33, which are functional parts, to the vertical attachment 26, the dimensions of the saddle members 21, 22, and 23 can be reduced. The appearance design of the shoji 20 can be further improved. Even if the size of the saddle members 21, 22, and 23 is thus reduced, the in-plane rigidity of the shoji 20 is increased as described above by forming the shoji 20 by bonding the panel material 24. Therefore, product performance can be secured.
