Description

  The present invention relates to a joint material that can stably attach a long member to a base material without rattling, and a long member attachment structure using the joint material.

  When attaching a member on a substrate, the most common attachment means is nailing or screwing. However, when nailing or screwing, the head is exposed on the surface of the member to be attached, and the appearance of the attachment structure is impaired. Therefore, another cover material is attached so that the head portion is not exposed on the surface, or a hole is provided and driven so as to fill the hole after nailing or screwing.

  FIG. 6 shows a specific example in which the member A is attached to the member B by screwing. The screw (A) reaches the member B through the member A. However, the head of the screw (A) is exposed on the surface of the member A, and post-processing is required to cover the head so that the head cannot be seen. If the members A and B are long materials, the heads of a plurality of screws (b), (b). Further, when the member A is screwed in a state where the member A is placed on the surface of the member B, the member A may be misaligned during the screwing process. For example, when the screw is tightened while being tilted with respect to the surface of the member B, the member A is laterally displaced. This lateral shift occurs more remarkably when the member A is hit.

  FIG. 7 shows another joint structure in which the member A is attached to the member B. A concave groove is formed on the surface of the member B, and a convex portion (B) is provided on the member A. The convex portion (B) is fitted into the concave groove and fixed so as not to come off through an adhesive. Yes. In order to obtain such a mounting structure, the surface of the member B must be grooved, and the member A must be provided with a convex portion (b). For this purpose, the number of processing steps is increased and a material having a large size is required.

  On the other hand, the member A attached by nailing, screwing and groove fitting is completely fixed to the member B and cannot be easily removed. Moreover, if the member A is a door stop, there is no effect | action which absorbs the impact at the time of closing a door. Therefore, the impact of the door is directly received. Of course, the reaction force also acts on the door, and the door contact and the door surface are scratched. Also, a loud impact sound is generated when the door is closed. Therefore, in general, a cushioning material is attached to the door contact surface.

“Door per door and door stop structure” according to Japanese Patent Application Laid-Open No. 2004-124464 is a door stop attached to a door frame or the like, and the door frame, the sliding door frame, and the open frame are composed of a common frame material, It is not necessary to provide a fitting groove for attaching the door stop to the door frame, and the door stop is configured to uniformly contact the door stop when the door is closed.
Therefore, the door stop is composed of two pieces, a base and a cover material, a long hole extending in the width direction is formed in the base bottom piece having a substantially U-shaped cross section, and the cover material is fixedly attached to the base.

The “door stop structure and its mounting method” according to Japanese Patent Application Laid-Open No. 11-30073 is aimed at a door stop having a good appearance with simple mounting.
Therefore, a door stop member composed of a long and narrow door receiving portion having locking portions formed on both sides and a door stopping portion having a locking portion that engages with the locking portion is formed on the front surface of the door frame member. Only the door stop receiving portion is fixed by a nail in the recessed groove.

  Thus, there are various structures for attaching another member to a certain base material, but there are problems as described above. The problem to be solved by the present invention is this problem, which is simple and can be stably attached without rattling and can be removed as required, while being able to counteract some impact. Provide a mounting structure and its joint material.

  The member to which the present invention is attached is a long member having a predetermined cross section, and the attachment structure of the long member is formed using a resin-made joint material. The Jonto material is a strip-like long material, and has a plurality of small protrusions continuously on the surface, and at least the surfaces of both side edges form a surface layer made of a soft resin. The base is made of a hard resin, and a soft resin surface layer is formed on both side edges of the base. Here, the cross-sectional shape of the protrusion is not particularly limited, but generally the tip is pointed as a triangular cross-section.

  By the way, a concave groove is provided on the surface of the base material, and the concave groove is also formed on the side of the long member to be similarly attached. About half of the joint material fits into the groove of the base material, and the groove formed in the long member to be attached fits into the joint material protruding from the surface of the base material. Since the surfaces of both side edges of the Jonto material are formed of a soft resin, they can be fitted into the concave groove with some compression deformation.

  In the present invention, the long member to be attached is attached via a resin joint material. Therefore, the base member and the long member to be attached can be provided by providing a narrow groove and fitting the joint material into the groove. Even if the width dimension of the concave groove is slightly different, the joint material can be fitted and attached without rattling by providing a surface layer made of a soft resin on the surface, and can be removed if necessary.

  Since the joint material is made of resin, when an impact is applied to the long member to be attached, the joint material can be deformed and has an effect of absorbing the impact. Therefore, if it is used as a door-to-door mounting structure, a large impact is not generated on the door and the door, and noise at the time of closing the door is reduced. Further, since the joint material has an effect of absorbing an impact, it is not necessary to provide a large cushioning material on the door contact surface as in the conventional case.

  FIG. 1 shows a case where the door 1 is attached to the portal frame 2 in a half-open state. The portal frame 2 is constituted by a frame composed of an upper frame 3 and both vertical frames 4a and 4b. The door 1 is mounted on the right vertical frame 4b through a joint 5 and 5 such as a hinge so as to be opened and closed. . A handle 6 is attached to the front end of the door 1 and can be opened and closed by grasping the handle 6.

  By the way, a door stop 6 is attached to the left vertical frame 4a, and when the door 1 is closed, it hits the door stop 6 and stops. FIG. 2 is an AA cross-sectional enlarged view of FIG. 1, and a door stop 6 is attached via a joint material 7 according to the present invention. A narrow groove 9 is cut in the surface 8 of the vertical frame 4 a, and a narrow groove 10 is also formed in the door stop 6. The joint material 7 straddles both the grooves 9, 10. Are mated.

  Here, the concave groove 9 is provided over the entire length of the vertical frame 4 a, and the concave groove 10 is also formed over the entire length of the door stop 6. When attaching the door stop 6 to the vertical frame 4 a, the joint material 7 is fitted into the concave groove 9, and the concave groove 10 is fitted to the joint material 7 protruding from the surface 8. Alternatively, the joint material 7 may be fitted in the groove 10 of the door stop 6 in advance, and the tip of the joint material 7 protruding from the groove 10 may be fitted in the groove 9 of the vertical frame 4a. Thus, in this invention, although the door stop 6 is attached via the joint material 7, the elongate member used as attachment object is not limited to the door stop 6 of an Example. The attachment structure of the door stop 6 shown in FIG. 2 is only one specific example.

  FIG. 3 shows a cross section of the joint material 7. The joint material 7 is made of resin, and further includes a base portion 11 made of a hard resin and surface layers 12a and 12b made of a soft resin. And the joint material 7 is a strip | belt-shaped body of fixed width, The several small protrusion 13, 13, ... is provided in the surface. The protrusion 13 of the joint material 7 shown in the figure has a triangular cross section and a sharp tip, but is not necessarily limited to this cross sectional shape.

  The protrusions 13, 13... Are provided on the surfaces of the surface layers 12a, 12b and the surface of the base 11 at substantially equal intervals, and extend continuously in the longitudinal direction. The joint material 7 shown in the figure is provided with surface layers 12a and 12b made of soft resin at both side edge portions (upper and lower portions in the drawing), and the base portion 11 made of hard resin is exposed at the center portion 14. . And although the protruding base 13,13 ... is provided also in the exposed base part 11, this protrusion 13,13 ... may not be provided in the center part 14.

  As shown in FIG. 2, the joint material 7 is fitted into the concave groove 9 formed in the vertical frame 4a. The concave groove 9 is fitted with the surface layer 12b on one side and the exposed base 11 portion. The portion of the surface layer 12 a on the other side protrudes from the surface 8. Therefore, the surface layer 12a is fitted and attached to the recessed groove 10 of the door stop 6. The joint material 7 is not easily detached by fitting up to the central portion 14 of the base 11 made of hard resin in the concave groove 9 of the vertical frame 4a, and the joint material 7 is also concave groove when the door stop 6 is removed. You will never leave 9

  Therefore, when the door 1 is closed, the door 1 hits the door stop 6 and stops. At this time, the impact force P acting on the door stop 6 is caused by compressive deformation and the base portion of the surface layer 12a made of soft resin. 11 is somewhat relaxed by bending deformation. Therefore, the impact sound generated when the door 1 hits the door stop 6 is also reduced. Of course, it is free to attach the cushioning material to 15 on the contact surface of the door 6 against which the door 1 hits, and the load applied to the joint material 7 is further reduced by providing the cushioning material.

  FIG. 4 shows another specific example of the present invention, in which a tip member 16 is attached via a joint material 7 to a wall tip constituting a door pocket. The sliding door 17 slides to open and close the doorway. When the sliding door 17 opens the doorway, the sliding door 17 is accommodated in a door pocket constituted by both walls, and when the sliding door 17 is closed as shown in FIG. The door bottom 17 is guided by a fixing member and a tip member 16 attached to the fixing member. Therefore, even if the sliding door 17 comes off the rail, it does not fall down. Further, the tip member 16 can be covered so that the inside of the door pocket cannot be seen.

  By the way, if the tip member 16 is screwed or fixed by nailing, it will be an obstacle when the sliding door 17 is removed. In the present invention, the tip member 16 is attached via the joint material 7 so that the attachment structure can be easily removed at any time. FIG. 5 is an enlarged cross-sectional view of the tip member 16 attached to the fixing member 18 provided at the tip of the wall via the joint material 7. Here, the fixing member 18 and the tip member 16 are long materials having a square cross section, and the joint material 7 is a long material shown in FIG.

  Therefore, as shown in FIG. 5, the joint member 7 is fitted almost uniformly into the concave groove 9 formed in the fixing member 18 and the concave groove 10 formed in the distal end member 16, and the distal end member 16 is attached. .
