  In such a conventional joinery, particularly in a pair of bathroom-side vertical seal members, the bathroom-side vertical seal member on the suspending side is mounted on the vertical frame. Extreme deformation accompanying opening and closing of the door body at the tip is suppressed, and durability can be sufficiently maintained. However, the bathroom side vertical seal member on the door end side mounted on the vertical frame has a problem of extremely poor durability because the door latch of the door body gets over every time the door body opens and closes. For this reason, in an actual thing, the part of the bathroom side vertical sealing member corresponding to a door latch is notched at the sacrifice of the sealing performance of this part.

  This invention makes it a subject to provide the fitting which can improve the durability of a door-end side sealing member and a suspension origin side sealing member, without sacrificing sealing performance.

The joinery of the present invention is a doorside seal that seals between a doorside vertical fence and a doorside vertical frame facing the doorframe in a fitting in which a shoji with a latch is opened and closed to the outdoor side in the form of an open door to the joinery frame A door-side seal member is provided on the outdoor side with respect to the latch, and a door-side seal member that seals between a member and a suspension-side vertical frame and a suspension-side vertical frame facing the member. Is attached to the door side vertical frame, the suspension side seal member is attached to the suspension side vertical frame, the tip part is closely attached to the suspension side vertical frame, and the door side vertical frame is found. A latch receiver corresponding to the latch, and a seal that is disposed in the vicinity of the latch receiver so as to be disengaged from the latch receiver in the prospective direction, and in which the front end of the door-end side seal member is intimately contacted from the outdoor side And a receiving protrusion .

In this case, it is preferable that the seal receiving protrusion is formed in a bulging shape at the tip.

According to these configurations, in the door-end side seal member and the suspension-end side seal member provided on the outdoor side, the latch is attached to the door end when the door sliding door is opened and closed by mounting the door-end side seal member on the door-end vertical fence. A structure overcoming the side seal member can be avoided. In addition, by mounting the hanging side seal member on the hanging side vertical frame, it is possible to avoid a structure in which the hanging side seal member repeatedly deforms excessively when opening and closing the shoji.
Furthermore, the contact force of the door-end side seal member to the seal receiving projection can be increased while maintaining the effective contact area between the tip of the door-end side seal member and the seal receiving projection.
In addition , the outdoor side in this case mainly means the outdoor side and the water field side with respect to the indoor side.

  In these cases, it is preferable that the suspension side vertical frame has the seal attachment protrusion formed in the tip bulge shape while the suspension side seal member is attached in a pinched state.

  According to this configuration, the suspension side seal member can be easily attached to the seal attachment projection by retrofitting, and the suspension side seal member can be easily replaced. In addition, the seal mounting projection can reduce the size in the prospective direction as compared with the dovetail type, so the degree of freedom such as the screw position for fixing the suspension side vertical frame to the housing side is maintained. be able to.

  In this case, it is preferable that the seal receiving protrusion and the seal mounting protrusion are formed in the same cross-sectional shape and are disposed at opposing positions.

  According to this configuration, the seal receiving protrusion and the seal mounting protrusion do not become an obstacle to making the door-end side vertical frame and the suspension side vertical frame have the same cross-sectional shape.

  In these cases, the suspension-side seal member is integrally formed with the base-side hard resin portion and the tip-side soft resin portion, and the suspension-side seal member is retrofitted to the seal mounting protrusion on the hard resin portion. It is preferable that a substantially keyhole-shaped mounting groove is formed.

  According to this configuration, it is possible to prevent the suspension side seal member from dropping off easily without impairing the sealing performance and while allowing the attachment of the suspension side seal member to the seal attachment projection to be retrofitted.

  As described above, according to the joinery of the present invention, when opening and closing the shoji, it is possible to avoid a structure in which the latch rides over the door-end side seal member, and avoid a structure in which the suspension side seal member repeats excessive deformation. Therefore, the durability of both seal members can be improved without sacrificing the sealing performance of both seal members. Therefore, a joinery that exhibits stable sealing performance can be provided.

In this case, particularly, the space between the lower frame 12 and the lower collar 22 is triple-sealed by the long seal piece 77b, the short seal piece 77c, and the lower frame seal member 44.

  Here, with reference to FIG. 3 and FIG. 4, it is detail about the seal structure between the door-end side vertical frame 13 and the door-end vertical rod 23, and between the hanging origin side vertical frame 14 and the hanging origin vertical rod 24. Explained. As described above, in the undressing room B side between the door-end side vertical frame 13 and the door-end vertical frame 23, both vertical frame seal members 57 that are in close contact with the door-end vertical frame 23 and the hanging vertical wall 24, 57, and on the bathroom A side, the seal is provided by the door-end side sealing member 89 and the hanging-end-side seal member 59 that are in close contact with the seal receiving projections 55a of the door-end vertical frame 23 and the door-end side vertical frame 13, respectively. Done.

  A vertical seal seal mounting portion 83 to which the door-end side seal member 89 is mounted has a mounting groove portion 83a having a substantially circular cross section having an open portion on the oblique dressing room B side. Further, the seal receiving protrusion 55a of the door-end side vertical frame 13 with which the door-end side seal member 89 is in close contact is formed with a circular bulge shape, more specifically, a cross-sectional keyhole shape. Further, the seal receiving protrusion 55a is disposed at a position somewhat closer to the bathroom A side than the finding surface on the bathroom A side of the closed door body (door-end vertical rod 23) 3. That is, the seal receiving protrusion 55a is disposed at a position near the bathroom A side in the prospective direction with respect to the latch receiver 58. More specifically, the rising slope 88a of the door latch 88 during the closing operation of the door body 3 is caused by the projecting dimension of the tip of the seal receiving protrusion 55a, the projecting dimension of the latch receiver 58, and the proximity of both. The front end of 55a and the end of the latch receiver 58 on the side of the bathroom A are almost at the same time (see the phantom line in the figure). As a result, the door latch 88 is smoothly engaged with the latch receiver 58.

  On the other hand, the door-end side seal member 89 includes a circular portion 101a inserted into and mounted on the mounting groove 83a and a U-shaped portion 101b extending from the circular portion 101a to the dressing room side along the groove edge. The mounting portion 101 and the contact portion 102 including the contact piece 102a extending from the U-shaped portion 101b so as to bend toward the seal receiving protrusion 55a and the boss portion 102b protruding from the base of the contact piece 102a are integrated. Is formed. The contact piece 102a is formed so as to be gradually thinned toward the tip, and the boss portion 102b contacts the outer surface of the vertical seal mounting portion 83 so that the contact piece 102a comes into strong contact with the seal receiving projection 55a. At the same time, the base side of the contact portion 102 is provided with rigidity. The mounting portion 101 is made of a hard resin, and the contact portion 102 is made of a soft resin, which are integrally formed by so-called two-color molding. In a state where the door body 3 is closed, the door-end side seal member 89 is slightly deformed in the reverse warping direction from the free state, and is strongly in close contact with the seal receiving protrusion 55a from the bathroom A side.

  The seal mounting protrusion 55b to which the suspension side seal member 59 is mounted has the same form (cross-sectional keyhole shape) as the above-described seal receiving protrusion 55a and is disposed at the same position in the prospective direction. In this way, the portion where the suspension side seal member 59 is mounted is not a general dovetail groove but a seal mounting projection 55b which is a keyhole-shaped projection, so that the seal mounting projection 55b itself has a short dimension in the expected direction. Can be formed. Thereby, the freedom degree of the screwing position (position of a prospective direction) of the fixed screw C which fixes the hanging base side vertical frame 14 to a unit bus | bath can be raised.

  The hanging side seal member 59 is in close contact with the arcuate portion 91a on the bathroom A side of the hanging side wall 24. Further, the suspension side seal member 59 has a base mounting portion 104 having a substantially right-angled triangular cross section having a mounting groove 104a that is substantially complementary to the seal mounting protrusion 55b, and from the base mounting portion 104 toward the suspension base vertical shaft 24. It is integrally formed with a contact piece portion 105 that is bent and extends in a substantially “H” shape. Unlike the door-end-side seal member 89 that is mounted on the front end, the suspension-side seal member 59 is configured to be mounted on the back-end, so that the mounting groove 104a that is mounted in the swallowed state has an open end. The part is chamfered (substantially keyhole shape). That is, the suspension side seal member 59 is detachably mounted on the seal mounting projection 55b from the front surface with the chamfered portion as a guide.

  Further, the contact piece 105 is formed so as to gradually become thinner toward the tip. Also in this case, the base mounting portion 104 is made of a hard resin, and the contact piece portion 105 is made of a soft resin, which are integrally formed by so-called two-color molding. In the state where the door body 3 is closed, the suspension side seal member 59 is slightly deformed in the reverse warping direction from the free state, and is strongly in close contact with the arcuate portion of the suspension side wall 24 from the bathroom A side (see FIG. Virtual line reference).

  As described above, according to the present embodiment, in the door-end side seal member 89 and the hanging-end side seal member 59 disposed on the bathroom A side in the prospective direction, the door-end side seal member 89 is replaced with the door-end vertical rod 23. By mounting, the door latch 58 does not get over the door-end side seal member 89 when the door body 3 is opened and closed. Further, by attaching the suspension side seal member 59 to the suspension side vertical frame 14, it is possible to make a structure in which the suspension side seal member 59 does not excessively repeat deformation when the door body 3 is opened and closed. Therefore, it is possible to improve the durability of the door-end side seal member 89 and the hanging-end side seal member 59 while maintaining good sealing performance.

  Further, since the seal mounting protrusion 55b has a keyhole shape and the suspension side seal member 59 is mounted on the keyhole shape, the suspension side seal member 59 can be easily replaced from the beginning. Further, since the seal receiving projection 55a and the seal mounting projection 55b have the same cross-sectional shape and are provided at the left and right symmetrical positions, even if the mounting form of the seal members 59 and 89 is different, the door tip The side vertical frame 13 and the hanging base side vertical frame 14 can have the same cross-sectional shape.

  In addition, the form of the door-end side sealing member and suspension base side sealing member of this invention is not limited to the thing of the said embodiment. Further, the present invention can be applied to doors of water fields such as shower rooms as well as bathroom doors, and can also be applied to exterior fittings such as open windows.

It is a longitudinal cross-sectional view of the bathroom door (bathroom fitting) which concerns on embodiment of this invention. It is a cross-sectional view of the bathroom door according to the embodiment. It is an expanded cross-sectional view around the door-end vertical fence. FIG.
