Description

  The present invention relates to a fitting for a sliding door.

In wooden buildings such as wooden houses, wooden fittings are often used as sliding doors used to open and close the entrances and exits of buildings and rooms. Since a wooden joinery is likely to warp, a technique for preventing the warpage of the joinery has been proposed (see, for example, Patent Document 1).
However, many of the conventional warpage prevention techniques considerably complicate the structure and manufacturing process of joinery. In addition, most of the conventional warpage prevention techniques are intended only for preventing warpage, and few have other functions.

  An object of the present invention is to provide a sliding door fitting that is excellent in warpage prevention performance, has a relatively simple structure, and can be easily opened and closed by many people.

  The present invention relates to a wooden joinery body in which longitudinal grooves are formed on each of two side surfaces located in the front and back in the sliding direction, and two side edges having a convex shape in cross section having a base and a protrusion that is thinner than the base. A sliding door fitting comprising a forming material, wherein each of the two side edge forming materials is made of a metal material partly or entirely of the protruding portion, and the protruding portion is fitted into the vertical groove. It is fixed to the two side surfaces of the joinery body in a combined state, and a groove that can be used as a pull is formed between the base portion of at least one of the side edge forming members and the side face of the joinery body. The above-mentioned object is achieved by providing a fitting for a sliding door.

  The fitting for a sliding door of the present invention is excellent in warpage prevention performance, has a relatively simple structure, and can be opened and closed easily by many people.

Hereinafter, the fitting for the sliding door of the present invention will be described based on its preferred embodiments.
FIG. 1 is a perspective view showing a sliding door fitting 1 according to an embodiment of the present invention, and FIG. 2 (a) is a partial cross-sectional view taken along the line II-II in FIG.
The joinery 1 of this embodiment (hereinafter, also referred to as joinery 1) is a sliding door joinery that slides while being guided and slid by grooves and rails arranged above and below the entrance of a building or room.

As shown in FIGS. 1 and 2, the joinery 1 includes a joinery body 2 and two side edge forming members 3 and 3. The joinery body 2 is wooden. Wood mainly uses wood or a material derived from wood, and the wood or wood-derived material includes solid wood, laminated wood, plywood, LVL, MDF, particle board, and the like.
As the joinery body 2, one having the same structure as a conventional joinery can be used, for example, a combination of a plate material and a rod-like material, or a whole made of a single thick plate. Can be used. As shown in FIG. 3, the combination of the plate material and the rod-shaped material includes both surfaces of a rectangular frame 45 including two upper and lower frame members 41 and 42 and two left and right frame members 43 and 44. Each of which plate members 46 and 47 are fixed to each other can be used. A reinforcing member 48 may be arranged inside the rectangular frame 45 in a manner as shown in FIG. 4, for example.

  As shown in FIGS. 1 and 2, the joinery body 2 has a U-shaped vertical groove 23 formed on each of two side surfaces 21 and 22 positioned in the front and rear of the sliding direction (X direction in the drawing). In the joinery 1 of this embodiment, the vertical groove 23 is formed in substantially the same shape on one side surface 21 and the other side surface 22 of the joinery body 2, and side edge portions having the same configuration are formed via the vertical groove 23. Since the materials 3 and 3 are fixed in the same manner, the following description will mainly be made on one side 21 side, but the same applies to the other side 22 side.

  The longitudinal groove 23 formed on the side surface 21 of the joinery body 2 is formed along the longitudinal direction of the side surface 21 at the center in the width direction of the side surface 21. The longitudinal groove 23 in the present embodiment is formed over substantially the entire length in the height direction of the joinery body 2.

  Then, a side edge portion forming material 3 having a convex cross section shown in FIG. The side edge portion forming material 3 has a length similar to the length in the longitudinal direction of the side surface 21 of the joinery body 2. The length of the side edge portion forming material 3 is preferably 60% or more of the length in the longitudinal direction of the side surface 21 of the joinery body 2 (the length in the Y direction in FIG. 1), more preferably 80 to 100%. Preferably, it is 90 to 100%.

As shown in FIG. 2, the side edge portion forming material 3 includes a base portion 31 having a relatively thick thickness, which is a dimension in the same direction as the thickness direction of the joinery body 2, and a ridge portion having a thickness in the same direction thinner than the base portion 31 32 is a long material having a convex cross section.
The ratio (T1 / T2) of the thickness T1 of the base 31 [see FIG. 2B] to the thickness T2 of the joinery main body 2 [see FIG. 2B] (T1 / T2) can be, for example, 50 to 200%. The depth of the groove that can be used as a puller, as described below, from the viewpoint of not interfering with the door pocket or the other fitting when the 1 is housed in the door pocket or when the two pieces are combined to form a sliding door From the viewpoint of ensuring the above, the ratio (T1 / T2) is preferably 70 to 130%, more preferably 80 to 120%, and even more preferably within 100% ± 5%.

The protruding portion 32 protrudes from the central portion of the base portion 31 in the thickness direction, and is formed over the entire length of the base portion 31 and the side edge portion forming material 3. As shown in FIG. 2, the protrusion 32 in the present embodiment has a surface formed of a long metal material 33 having a U-shaped cross section, and the interior 34 is a material forming the base 31. It is formed from a wood or a wood-derived material that is integral with the wood.
The long metal material 33 having a U-shaped cross section is called a commercially available metal material, for example, a so-called C-type channel material that is used for a field edge receiving material or a member for building a main frame structure of a metal ceiling base. A metal material etc. can also be used. Examples of the forming material of the metal material 33 include iron (including steel materials such as carbon steel and stainless steel), aluminum, and other various materials used as materials for building hardware and metal fittings.

In the side edge portion forming material 3, a portion having a predetermined width from the tip of the ridge portion 32 is fitted in the vertical groove 23. The fitting in the present invention includes a fitting in which the entire protrusion 32 is accommodated in the vertical groove 23. The fitting of at least one side edge forming member 3 is as shown in FIG. Further, the fitting is such that a predetermined gap is formed between the base 31 and the side surface 21 of the joinery body.
In the joinery 1 of the present embodiment, a predetermined gap is formed between the base portion 31 and the side face 21 of the joinery main body as shown in FIG. Thus, grooves 5 that can be used as pullers are formed on the front and rear sides of the fitting 1 in the sliding direction. In addition, holes 35 are formed at predetermined intervals in the longitudinal direction of the side edge portion forming member 3 and, as shown in FIG. 2A, through these holes 35, rods such as screws and nails are formed. The side edge portion forming material 3 can be firmly fixed to the joinery body 2 using the fixture 6.

According to the joinery 1 of the present embodiment, the ridges 3 of the side edge portion forming material 3 imparted with high bending rigidity by the metal material 33 are fitted in the vertical grooves 23 on the side surface of the joinery body 2. In spite of having the wooden joinery body 2, warping is unlikely to occur. Such an effect is particularly beneficial when the height of the joinery is made higher than a general one.
From the viewpoint of preventing warpage, the fitting depth (depth of the longitudinal groove 23) D [see FIG. 2 (a)] of the ridge to the joinery body 2 is preferably 2 to 50 mm, more preferably 3 It is -30 mm, More preferably, it is 5-20 mm.

Moreover, according to the joinery 1 of this embodiment, since the side edge part formation material 3 is being fixed so that the groove | channel 5 which can be used as a puller is formed between the base 31 and the side surface 21, When used as a fitting for a sliding door, as shown in FIG. 1, the groove 5 exists over a wide range in the height direction.
Therefore, both a short person and a tall person can slide the joinery 1 by placing the hand in a position where the hand can be easily placed according to his / her height. The same applies to those who use wheelchairs, and the joinery 1 can be pulled and slid by reaching the most comfortable height.
Thus, according to the joinery 1 of the present embodiment, many people can easily perform opening and closing operations, which is excellent from the viewpoint of universal design.

  From the viewpoint of making the groove 5 easy to use as a puller, the width W [see FIG. 2 (a)] between the base 31 and the side surface 21 of the joinery body 2 is preferably 7 to 50 mm, more preferably. 10-30 mm. From the same viewpoint, the depth of the groove 5 (in this embodiment, 1/2 of the difference between the thickness T1 of the base portion 31 and the thickness T3 of the protruding portion 32) is preferably 3 to 40 mm, more Preferably it is 5-30 mm.

  Furthermore, according to the joinery 1 of this embodiment, when it uses so that it may accommodate in a door pocket, there also exists an advantage that the pressing edge by the side of a door pocket is also unnecessary.

As mentioned above, although one Embodiment of this invention was described, this invention is not restrict | limited to the said embodiment, It can change suitably.
For example, in the above embodiment, the grooves 5 and 5 that can be used as pullers are formed on the front and rear in the sliding direction of the joinery 1, but only one of the two side surfaces 21 and 22 of the joinery body 2 The side edge forming material 3 may be fixed so that such a groove 5 is generated, and the side edge forming material 3 may be fixed to the other so that such a groove 5 is not generated.
Further, the side edge portion forming material 3 may have a structure as shown in FIG. In the side edge part forming material 3 shown to Fig.5 (a), the inside of the protrusion part 32 which consists of the metal material 33 of a cross-sectional U-shape is hollow. In the side edge portion forming material 3 shown in FIG. 5 (b), the ridge portion 32 is made of a metal tube (long material) 33A having a square cross section.
