Description

  The present invention belongs to a technical field related to a sliding door rail device for movably installing a semi-automatic opening / closing type sliding door that is manually opened and closed using gravity without a driving mechanism.

  Semi-automatic sliding doors usually have slanted rails that guide the travel of the runner body that holds the door plate, and the closed door plate automatically descends the runner body with its own weight along the rail ( It is configured to be released by running). For this reason, about the semiautomatic opening / closing type sliding door, the demand for installation is increasing in various buildings including a general house where it is difficult to provide a drive mechanism.

Conventionally, as a semi-automatic opening / closing type sliding door, for example, the following are known.
Japanese Patent Application Laid-Open No. 2001-164829 discloses a semi-automatic opening / closing type sliding door in which a rail is attached to an attachment plate called a lintel inclined to a door frame or a wall surface.

  In the semi-automatic opening / closing type sliding door according to Patent Document 1, since it is necessary to perform the installation work while adjusting the inclination of the long mounting plate and rail, it is difficult to obtain the accuracy of the inclination (gradient) of the rail arrangement. There is a problem that there is. Moreover, since the construction | work of the procedure different from the normal procedure which attaches a rail to an upper door frame is requested | required, there exists a problem that construction is troublesome. Moreover, since the attachment plate which is another member will be provided in the door frame vicinity, there exists a problem that the trap of the door plate to a door frame worsens.

  The present invention has been made in consideration of such problems, and it is intended to provide a sliding door rail device that can attach a rail to an upper door frame with a simple construction without using a separate member with high accuracy. Let it be an issue.

  In order to solve the above-described problems, the sliding door rail device according to the present invention employs means described in each of the claims.

  In other words, in claim 1, a rail for guiding the run of the runner body that suspends the door plate, and a screw hole that is interposed between the rail and the upper door frame and through which mounting screws are inserted vertically into the upper door frame. And a plurality of space blocks with different heights, and a connecting structure for connecting the rails and the space blocks is provided between the upper part of the rails and the lower part of the space block. The space blocks are arranged so that the height sequentially increases toward the closed side of the door plate.

  In this means, the construction of a normal procedure for attaching the rail to the upper door frame is performed, and a space block that is connected to the rail and is not a separate member reliably forms an inclination in the rail with the upper door frame. The space block forms a space between the upper door frame and the rail.

  According to a second aspect of the present invention, in the sliding door rail device according to the first aspect, the space block has a difference in height on both sides of the rail in the length direction.

  In this means, the upper surface of each space block is brought into contact with the lower surface of the upper door frame, so that a natural inclination is formed on the rail.

  According to a third aspect of the present invention, in the sliding door rail device according to the first or second aspect, the connection structure includes a connection groove provided on the rail side and a connection protrusion provided on the space block side, and the connection groove is a part of the upper part. Is formed in a box shape extending in the length direction of the rail, and the connection projection is formed in a plate shape that engages with the connection groove.

  In this means, the connection structure is an engagement structure of a box-shaped connection groove and a plate-shaped connection protrusion.

  According to a fourth aspect of the present invention, in the sliding door rail device according to the third aspect of the present invention, the connecting structure is characterized in that a piece of the connecting groove is crimped and fixed to the upper part of the connecting projection.

  In this means, the connecting projection is fixed by caulking of one part which is a part of the connecting groove of the connecting structure.

  According to a fifth aspect of the present invention, in the sliding door rail device according to the third aspect, the coupling structure is characterized in that the coupling projection is slidable in the length direction of the rail inside the coupling groove.

  With this means, the space block can be slid with respect to the rail to change the arrangement position of the space block.

  Moreover, in Claim 6, in the rail apparatus for sliding doors in any one of Claims 1-5, a space block is a surface turned to either the upper or lower side of the inclination of a rail in the surface which faced the length direction of the rail. It is characterized by a sign for confirming whether or not.

  With this means, the mounting direction of the space block with respect to the rail can be confirmed with a sign.

  In the sliding door rail device according to the present invention, the construction of the normal procedure for attaching the rail to the upper door frame is performed, and the space block that is connected to the rail and is not a separate member reliably tilts the rail between the upper door frame and the rail. Since it forms, there exists an effect which can attach a rail with sufficient precision by simple construction to an upper door frame, without using another member. Further, since the space block forms a space between the upper door frame and the rail, there is an effect that the noise generated between the rail and the runner body can be attenuated and the shock can be buffered.

  Hereinafter, the best mode for carrying out the sliding door rail device according to the present invention will be described with reference to the drawings.

  As shown in FIG. 1, this form includes a rail 1, a space block 2, and a connection structure 3.

  As shown in detail in FIGS. 2 and 3, the rail 1 is formed integrally with a part of the connection structure 3 (connection groove 31) by extrusion molding of a lightweight metal material or the like. It is formed in a box shape that is partially opened and extends in the length direction, and the unopened pieces 12 on both sides of the open portion 11 serve as a running surface of the runner body R that holds the door plate D, and the upper door Screw holes 13 through which the mounting screws 4 to the frame F are inserted are opened at regular intervals.

  As shown in detail in FIGS. 2 and 3, the space block 2 is integrally formed with the other part of the connection structure 3 (connection protrusion 32) by injection molding of a synthetic resin material or the like. The heights a and b of the short surfaces 21 and 22 on both sides that face the length of the rail 1 are slightly different, and the bottom surface 23 is formed in a substantially rectangular parallelepiped shape inclined at a slight angle c. A screw hole 24 through which the mounting screw 4 is inserted is penetrated in the vertical direction of the central portion. For the space block 2, a plurality of different heights are prepared for one rail 1.

  The connecting structure 3 includes a connecting groove 31 provided on the rail 1 side and shaped like a two-stage box together with the rail 1, and a connecting protrusion provided on the space block 2 side and shaped like a T-shaped block together with the space block 2. 32. The connecting groove 31 is formed in a box shape that is partially opened at the top and extends in the length direction of the rail 1, and is provided with unopened pieces 31 b on both sides of the open portion 31 a. The connection protrusion 32 is formed in a plate shape that engages with the connection groove 31.

  In order to assemble this form, the connecting protrusion 32 is inserted into the connecting groove 31 of the connecting structure 3 from the end in the length direction of the rail 1, and the space block 2 (to the connecting groove 31 of the connecting structure 3 is connected to the rail 1). The connecting protrusion 32) is slid. Then, a plurality of space blocks 2 are arranged on the rail 1 at intervals so that the screw holes 24 of the space block 2 are aligned with the screw holes 13 of the rail 1 and the connecting structure 3 is secured and engaged. Let Thereafter, the rail 1 and the space block 2 are connected by caulking and fixing the piece 31 b of the connection groove 31 of the connection structure 3 to the upper part of the connection protrusion 32. At this time, the space blocks 2 are arranged so that the height increases sequentially toward the closed side of the door plate D.

  In order to install this configuration, as shown in FIG. 1, the upper surface of the space block 2 is brought into contact with the lower surface of the upper door frame F, and the mounting screws 4 are inserted from the open portion 11 of the rail 1. The screw hole 13 and the screw hole 24 of the space block 2 are inserted and tightened to the upper door frame F.

  According to this installation, since the construction of the procedure different from the normal procedure of attaching the rail 1 to the upper door frame F is not required, the construction is not troublesome. Further, if the upper surface of the space block 2 is brought into contact with the lower surface of the upper door frame F, a predetermined inclination is formed from the difference between the heights a and b of the short surfaces 21 and 22 of the space block 2. . Accordingly, since it is not necessary to adjust the inclination of the long rail 1, it is possible to reliably obtain the inclination (gradient) accuracy of the arrangement of the rail 1. Moreover, since the rail 1 and the space block 2 are connected and integrated by the connecting structure 3, and the space block 2 is not a separate member projecting around the rail 1, the upper door frame F, side There is no case that the size of the door plate D becomes worse with respect to the partial door frame.

  In this embodiment, as shown in FIG. 4, the rail 1 is disposed so as to be inclined downward toward the closing side with respect to the upper door frame F by being installed. Accordingly, the opened door plate D is closed by automatically lowering (running) the runner body R, which is subject to its own weight, along the rail 1.

  In a state in which this configuration is installed, as shown in FIG. 4, a slight space is formed by the space block 2 between the upper door frame F and the rail 1. Since this space reduces the direct contact area between the upper door frame F and the rail 1, the noise generated between the rail 1 and the runner body R can be attenuated and the shock can be buffered. The effectiveness of the noise attenuation and shock buffering can be increased by adjusting the material of the space block 2.

  It should be noted that on-site construction as shown in FIG. That is, as shown in FIG. 5A, the space block 2 of the rail 1 having a required height is selected corresponding to the inclination of the rail 1 required at the installation site. Subsequently, as shown in FIG. 5 (B), the opening position of the screw hole 13 of the rail 1 is set corresponding to the inclination of the rail 1 required at the installation site, and the screw hole 13 is formed in the rail 1. The drilling work is carried out. Thereafter, as shown in FIG. 5C, the rail 1 and the space block 2 are assembled in the same manner as described above.

  In order to correspond to this construction on the site, one or both of the short surfaces 21 and 22 facing the length direction of the rail 1 of the space block 2 is a surface directed to either the upper or lower side of the inclination of the rail 1. It is preferable to provide a label 5 for confirming whether or not the above is true. In FIG. 5, a sign 5 made up of the characters “closed” is provided on the short surface 21 of the space block 2 on the closed side of the door plate D. This mark 5 is a slight difference in which the heights a and b of the short surfaces 21 and 22 of the pace block 2 are difficult to judge visually, but prevents an error in the assembly direction of the space block 2 with respect to the rail 1. To help.

  When the site construction as shown in FIG. 5 is performed, the adjustment of the inclination of the rail 1 becomes free, so that the automatic closing speed of the door plate D can be freely set.

  As described above, even if the rail 1 has a shape other than the box shape, it can be dealt with by changing the shape of the space block 2 and the connecting structure 3 in addition to the illustrated shape.

  Furthermore, the space block 2 can have a shape other than a rectangular parallelepiped shape.

  Furthermore, it is also possible to display the numerical value of the height or the identification number on the space block 2 to facilitate the selection of the arrangement of the space blocks 2 at the site construction.

  Furthermore, it is possible to partially provide the connection structure 3 at the connection position of the space block 2.

It is a perspective view which shows the example of the installation construction of the best form for implementing the rail apparatus for sliding doors which concerns on this invention. It is a longitudinal cross-sectional view of the principal part of FIG. It is a longitudinal cross-sectional view of FIG. It is a side view in the state where the door board was built in the installation of FIG. It is a perspective view which shows the site construction example of FIG. 1, and a construction process is shown in order of (A)-(C).
