JP5101863B2 - Mounting structure of L-shaped rail for hanging sliding door with door pocket - Google Patents

Description

  The present invention relates to an L-shaped rail mounting structure on which a door of a hanging sliding door having a door pocket is placed.

  Conventionally, an L-shaped rail for a hanging door is fixed to a base frame extending in and out of a door pocket with screws at predetermined intervals over the entire length. This L-shaped rail needs to be replaced if it becomes scratched or becomes heavily worn. However, recently, the door pocket is assimilated with the surrounding wall, so that the structure cannot be disassembled, or even the disassembleable structure can be extremely difficult to remove and attach. For this reason, various ideas have been made. For example, the L-shaped rail is divided into two parts, one for the interior of the door pocket and the other for the exterior of the door pocket. The external rail is simply screwed (see Patent Document 1) or the inside and outside of the door pocket is a single long rail. Inside the door pocket, the end of the rail is fixed with an end fixture, and the outside of the door pocket is fixed with screws. A thing (refer patent document 2) etc. are disclosed.

  However, in Patent Document 1, the configuration in which the door suspension is placed on the outer rail of the door pocket and the door butt suspension is placed on the inner rail of the door pocket has a disadvantage that the sliding door has to take a lot of unremaining portions that do not enter the door pocket. In order to fit completely in the door pocket, both the door tip and the door bottom suspension car must ride on the rail in the door pocket, so that every time the door is fully opened and closed, the suspension car always passes over the joint between the door inner and outer rails. There is an inconvenience that a passing sound is always emitted. In Patent Document 2, only the tip of the rail inside the door pocket is fixed, so in the case of a wide sliding door, the auxiliary bracket is on the fixed extension line of the rail, so the rail needs to be shortened accordingly. The rear suspension must be mounted in a considerable forward direction, which has a subtle effect on the balance during opening and closing, and no matter how much auxiliary brackets are present, only the rail ends are fixed, and the large bending moment due to the sliding door weight is There is an inconvenience that the mounting surface around the middle part of the door pocket may float and cause twisting. The present invention has been provided for the purpose of solving such disadvantages.

      The present invention has solved the inconvenience caused by the mounting structure in which a force is applied to the rail evenly without causing the L-shaped rail to be twisted. That is, the present invention is an L-shaped rail that is attached to an invisible base frame having a door pocket and is used to suspend the door of a hanging sliding door. Of the mounting holes provided in the L-shaped rail mounting surface, the interior of the door pocket is provided. A rail clip is provided for each of the mounting holes located, and an insertion hole for inserting the rail clip is provided in the base frame opposite to the rail clip mounting position, and the bottom of the L-shaped rail is mounted and accommodated in the door pocket. A rail mounting tool for mounting the bottom surface of the L-shaped rail is provided on the base frame at a position to be mounted, and the mounting of the L-shaped rail is performed by inserting a rail clip provided on the rail through the insertion hole, The exposed front surface of the rail clip is brought into contact with the back surface of the base frame so that the bottom surface of the L-shaped rail is in contact with the record frame. Attaching the L-shaped rail for hanging sliding doors having a door pocket, which is configured to be bolted by a mounting hole provided in an L-shaped rail mounting surface outside the door pocket after being mounted on the rack mounting tool Structure.

  The insertion hole of the present invention allows the rail clip already attached to the rail to be inserted without difficulty, and when the L-shaped rail mounting surface outside the door pocket is bolted, the exposed front surface of each rail clip after insertion is the base It is necessary to be able to contact the back side of the frame, and the rail mounting tool for mounting the bottom of the rail is provided only at the bottom of all the insertion holes, even if the rail length is the same as that inside the door pocket. It may be installed at an unexpected mounting position, and any of them may be used. When the L-shaped rail mounting surface outside the door pocket is bolted, the L-shaped rail inside the door pocket is a rail. What is necessary is just to be mounted on a mounting tool and to contact | abut to the base frame by the rail clip.

  The mounting structure of the present invention can be set by positioning the relative positions such as mounting screw holes outside the door pocket, rail clip mounting position and insertion hole position in the base frame in advance at the time of mounting work. In addition, the outer L-shaped rail mounting screw hole and the insertion hole can be easily formed. Similarly, the mounting position of the rail mounting tool can be confirmed, and the mounting screw hole can be easily formed. Moreover, there is no need to shorten the L-shaped rail, and the mounting holes provided in advance on the L-shaped rail can be used as they are, so there is no need to process the L-shaped rail, and each part that has been set and confirmed once in another location. As long as it is attached to the base frame setting installation location, it is possible to easily replace the L-type rail after it is sealed, and the weight of the sliding door suspended on the L-type rail is equally applied to the rail installation position. It will be.

  Embodiment 1 of the invention will be described with reference to the drawings. FIG. 1 is a front view in use after rail mounting, and FIGS. 2 and 3 are cross-sectional views taken along arrows AA and BB in FIG. 4 is a perspective view illustrating the base frame machining hole, FIG. 5 is an explanatory view of attaching the L-shaped rail to the base frame, and FIG. 6 is a cross-sectional view taken along arrow A2-A2 in FIG. It is a figure explaining the rail attachment point.

  First, the base frame 3 that is attached in an invisible manner is taken out, and the attachment position of the L-shaped rail 4 for suspending the sliding door 1 having the door wheel 9 is determined. At that time, it is first determined whether to use an inclined rail or a horizontal rail. Here, the horizontal rail will be described. First, when the attachment position to the base frame 3 of the L-shaped rail 4 in which attachment holes are provided at substantially equal distances in advance is determined, the base frame 3 as shown in FIGS. A rail attachment screw hole 5 is provided at an outer position of the door pocket 2, an insertion hole 7 of the rail clip 6 is provided at an inner position of the door pocket 2, and an L-shaped rail 4 is placed under the insertion hole 7. A mounting screw hole (not shown) of the rail mounting tool 8 to be placed is provided. A rail clip 6 is screwed in advance to each of the mounting holes corresponding to the internal position of the door pocket 2 among the mounting holes of the L-shaped rail 4. In this embodiment, the rail mounting tool 8 is provided with an angle material under each of the insertion holes 7, but this rail mounting tool 8 is a single long angle material connected to the bottom of the insertion holes 7 at both ends. The rail mounting tool 8 may be attached by screws or welding.

  When all of these holes and screws are finished, the base frame 3 is attached to an unambiguous set position with the rail mounting tool 8 mounted in advance as shown in FIG. The base frame 3 is fixed by screwing or welding. Next, the installation procedure of the L-shaped rail 4 will be described. The installation procedure is as shown in FIGS. 6A to 6D. The door of the L-shaped rail 4 in which the rail clip 6 is screwed and fixed in advance to the inner position of the door pocket. The in-vehicle mounting portion is lifted in a horizontal state (a), and the rail clip 6 is inserted into the insertion hole 7 provided in the base frame 3 (b), and the L-shaped rail 4 is raised so that the rail clip 6 is raised. The L-shaped rail 4 is raised until the front surface comes into contact with the back side surface of the base frame 3 (c). After the contact, the L-shaped rail 4 is placed on the rail mounting tool 8 as it is (d), and then outside the door pocket 2. It is only necessary to insert a screw into the mounting hole of the L-shaped rail 4 and fix the screw to the rail mounting screw hole 5 that has been drilled in advance. When removing, the L-shaped rail 4 can be easily removed by following the reverse of this procedure.

  Next, another example 2 will be described. In the example 1, the weight of the sliding door 1 inside the door pocket is supported by the rail clip 6 on the upper part of the back surface of the insertion hole 7, whereas the example 2 is inserted by the rail clip 6. It is configured to be supported by the back side lateral portion (side portion) of the hole 7. Since the drilling of screws for attachment to the base frame 3 and the prior setting of the rail mounting tool 8 are the same as in the first embodiment, the description thereof is omitted. FIG. 7 is a cross-sectional explanatory view when the L-shaped rail 4 is mounted using the rail clip 6 of the second embodiment. FIGS. 8 (e) and 8 (f) attach the L-shaped rail 4 to the base frame 3. It is explanatory drawing of the point to do.

  Since the procedure until the base frame 3 is mounted in an invisible manner is the same as that in the first embodiment, the procedure for mounting the L-shaped rail 4 from the next will be described. FIG. 8 (e) to FIG. 8 (f). As described above, with the rail clip 6 of Example 2 attached and fixed in advance, the L-shaped rail 4 is put into the door pocket as it is and lifted. First, a part of the bottom end of the L-shaped rail 4 is placed on the rail mounting tool 8. The insertion hole 7 can be easily found by moving it in the longitudinal direction a little back and forth so as to search for the insertion hole 7 at the tip of the rail clip 6. A plurality of rail clips 6 provided inside the door pocket are simultaneously vertically pushed into the insertion hole 7 to confirm that the mounting surface of the L-shaped rail 4 is in contact with the base frame 3. The front end of the rail clip 6 is automatically brought into contact with the rear surface of the base frame 3 when the end of the rail clip 6 is pushed and stopped. What is necessary is just to put a screw in an attachment hole and to fix the screw to the rail attachment screw hole 5 made beforehand. When removing, the L-shaped rail 4 can be easily removed by following the reverse of this procedure.
