Description

  The present invention relates to a structure for attaching a resin panel to a frame in a sliding door provided on the front surface of various cabinets.

  Various cabinets such as the cup board 11 shown in FIG. 3 have a sliding door 12 on the front surface. The sliding door 12 is opened and closed by sliding the sliding door 12 in the left-right direction, and the stored items are taken out and stored. Is possible.

  The doors 13 arranged at the front and rear of the sliding door 12 are generally formed by attaching a rectangular panel 15 inside a frame body 14 formed by assembling a hollow frame into a rectangle. A transparent or translucent resin panel has begun to be adopted as the panel 15 so that the inside of the cabinet can be visually recognized.

  FIG. 4 is a cross-sectional view of a principal part illustrating the mounting structure of the resin panel in the sliding door.

  The frame 14a has a receiving portion 16 into which an edge portion of the resin panel 15a is inserted. The receiving portion 16 is hollow and includes a first support portion 17 on one side and a second support portion 18 on the other side. Both the first support portion 17 and the second support portion 18 have a substantially L-shaped cross section, are arranged to face each other, and form a groove-shaped opening 19 therebetween.

  When attaching the resin panel 15 a to the frame 14 a, the end edge portion of the resin panel 15 a is inserted into the receiving portion 16 through the opening 19. Next, a packing 20 made of rubber or the like is press-fitted into the receiving portion 16 from the opening 19, and the edge portion of the resin panel 15 a is pressed toward the first support portion 17. Thus, the resin panel 15a is attached to the frame 14a via the packing 20.

  By the way, the resin panel 15a may expand due to environmental temperature or the like. In this case, as shown in an enlarged view of the main part in FIG. 5, the resin panel 15a expands in the length direction x, but the packing 20 provided for mounting the resin panel 15a is the edge of the resin panel 15a. The direction of the force f that presses the portion is the first support portion 17 side, and the force f acts to warp the resin panel 15a in the direction of the arrow y. The warp generated in the resin panel 15a in this way may cause the doors 13 arranged at the front and rear shown in FIG. 3 to come into contact with each other, which may hinder the opening and closing of the door 13.

  Patent Document 1 describes a structure in which a steel packing formed by bending a steel plate is fitted to the edge of the panel, and the edge of the panel is inserted into a recessed groove for fitting the panel formed in the sash frame. ing.

However, Patent Document 1 does not consider the warping of the resin panel 15a, and does not suggest the elimination of the contact between the front and rear doors 13 in the sliding door 12.
Utility model registration No. 3087071

  The present invention has been made in view of the circumstances as described above, and even if expansion occurs in the resin panel due to an increase in environmental temperature or the like, it is possible to eliminate the contact of the doors arranged at the front and rear in the sliding door. It is an object to provide a resin panel mounting structure in a sliding door.

  In order to solve the above problems, the present invention firstly includes a first support portion on one side of a hollow receiving portion formed on the frame and a second support portion on the other side so as to face each other. The resin panel inserted into the receiving portion through a groove-shaped opening formed between the first support portion and the second support portion is a resin panel mounting structure in a sliding door that is attached to the frame via a packing. The section width of the second support section is longer than the section width of the first support section, and the portion of the second support section that contacts the packing is bent obliquely toward the first support section within the receiving section. When the resin panel protrudes and expands, the resin panel is warped toward the second support portion.

  In the second aspect of the present invention, a guide portion having an inclined surface that is inclined obliquely toward the first support portion is disposed on an opposing surface portion that substantially faces the end portion of the resin panel in the receiving portion, The resin panel is expanded while guiding the end portion with the inclined surface of the guide portion, and the resin panel is warped toward the second support portion.

  Thirdly, according to the present invention, the surface of the edge portion of the resin panel inserted into the receiving portion is the first support portion by the packing press-fitted between the back surface of the resin panel edge portion and the second support portion. The end edge portion of the resin panel is sandwiched between the first support portion and the second support portion via the packing.

  According to the first invention of the present application, in the first support portion and the second support portion provided to face the hollow receiving portion formed in the frame, the cross-sectional width of the second support portion is the first width. The portion of the second support portion that is longer than the cross-sectional width of the support portion and that contacts the packing is bent obliquely toward the first support portion in the receiving portion and protrudes at the edge of the resin panel. The more applied force acts to warp the resin panel toward the second support portion having a long cross-sectional width. As a result, the resin panel does not warp on the first support portion side having a short cross-sectional width, and warps on the second support portion side having a long cross-sectional width. Since the second support portion having a long cross-sectional width can provide a space between the front and rear doors, the front and rear doors do not contact even if the resin panel is warped.

  According to the second invention of the present application, since the end portion of the resin panel is guided by the inclined surface of the guide portion and expands, the resin panel is more likely to warp to the second support portion side during expansion.

  According to the third invention of the present application, when the first support portion is arranged toward the outside of the cabinet, even if the resin panel is transparent, the packing used for mounting the resin panel is hardly conspicuous from the outside. And the appearance is improved.

  FIG. 1 is an enlarged cross-sectional view showing a main part of an embodiment of a resin panel mounting structure in a sliding door according to the present invention.

  The frame 1 is a hollow member, and forms a frame body of a sliding door by being assembled into a rectangle. A material in particular is not restrict | limited, It can be set to aluminum etc. which are widely used, and it can shape | mold easily by extrusion molding etc.

  A hollow receiving portion 2 is formed at a portion of the rectangular frame body located at the inner edge. The receiving portion 2 is a portion into which an end edge portion of the resin panel 3 attached to the inside of the frame body is inserted, with the first support portion 4 facing one side and the second support portion 5 facing the other side. I have. The sectional width w of the second support portion 5 is longer than the sectional width W of the first support portion 4 (w> W). Moreover, the front-end | tip part of the 2nd support part 5 bends and protrudes diagonally toward the 1st support part 4 in the receiving part 2, and is made into the bending protrusion part 5a. The first support portion 4 has a substantially L-shaped cross section, and the tip portion is an inward protruding end portion 4a. A groove-shaped opening 6 is formed between the first support portion 4 and the second support portion 5.

  The resin panel 3 is a rectangular plate that fits inside a rectangular frame assembled by the frame 1. By adopting the resin panel 3, the door can be made light and the operability as a sliding door is improved. The material is not particularly limited, and a general resin such as an acrylic resin can be used. In order to make the inside of the cabinet visible and to have a display function, the resin is preferably transparent or translucent.

  When the resin panel 3 is attached to the frame 1, the end edge portion of the resin panel 3 is inserted into the receiving portion 2 through the opening 6. In this state, the elastic packing 7 such as rubber is press-fitted between the back surface of the edge portion of the resin panel 3 and the second support portion 5 through the opening 6. Since the packing 7 is compressed in particular in the bending protrusion part 5a of the 2nd support part 5, the packing 7 presses the resin panel 3 to the 1st support part 4 side with big elastic force. As a result, the surface of the edge portion of the resin panel 3 comes into contact with the protruding end portion 4 a of the first support portion 4. Thus, the edge portion of the resin panel 3 is sandwiched between the first support portion 4 and the second support portion 5 via the packing 7, and the resin panel 3 is attached to the frame 1.

  While the resin panel 3 has the advantages as described above, the resin panel 3 may expand as the environmental temperature rises. However, in the embodiment shown in FIG. 1, a bent protruding portion 5 a that is bent obliquely toward the first support portion 4 and protrudes in the receiving portion 2 at the distal end portion of the second support portion 5 is disposed. Therefore, as shown in FIG. 2, even if the resin panel 3 expands in the length direction x, the force f with which the packing 7 presses the end edge of the resin panel 3 supports the resin panel 3 as the second support. It acts to bend toward the part 5 side. As a result, the direction z of the warp occurring in the expanding resin panel 3 is on the second support portion 5 side.

  Therefore, even if the resin panel 3 is warped, the resin panel 3 is not warped toward the first support portion 4 having a short cross-sectional width, but is warped toward the second support portion 5 having a long cross-sectional width. Since the space between the front and rear doors can be given a margin by the second support portion 5 having a long cross-sectional width, the front and rear doors do not contact even if the resin panel 3 is warped. The contact of the door arrange | positioned forward and backward in a sliding door can be eliminated.

  In the embodiment shown in FIG. 1, as described above, the packing 7 is press-fitted between the back surface of the edge portion of the resin panel 3 and the second support portion 5, and the surface of the edge portion of the resin panel 3. When the first support part 4 is arranged toward the outside of the cabinet, the packing 7 is used even if the resin panel 3 is transparent. Becomes inconspicuous from the outside and the appearance is good.

  Further, in the embodiment shown in FIG. 1, the guide portion 8 is disposed on the facing surface portion 2 a that substantially faces the end portion of the resin panel 3 in the receiving portion 2. The guiding portion 8 has a substantially trapezoidal cross section and has an inclined surface 8 a that is inclined obliquely toward the first support portion 4. Therefore, as shown in FIG. 2, when the resin panel 3 expands in the length direction x, the inclined surface 8 a of the guide portion 8 guides the end portion of the resin panel 3 and the second support of the resin panel 3. Warpage toward the part 5 side is more likely to occur.

  The mounting structure of the resin panel 3 shown in FIGS. 1 and 2 is for a frame disposed on the lower side of the frame body 14 as shown in FIG. 3, but is shown in FIGS. Further, the mounting structure of the resin panel 3 is equally applied to a frame arranged on the upper side of the frame body 14.

It is the principal part expanded sectional view which showed one Embodiment of the attachment structure of the resin panel in the sliding door of this invention. In embodiment shown in FIG. 1, it is the principal part expanded sectional view shown about generation | occurrence | production of the curvature when a resin panel expand | swells.
