The sliding door opening / closing operation puller provided on the door end side of No. 2 and reference numeral 6 indicate the floor surface, respectively. Since the lower ends of the vertical frames 12 and 12 substantially coincide with the floor surface 6, the lower frame is omitted.

The shape and configuration of each fixing member 20 will be described with reference to FIGS. 2 to 4. The fixing member 20 has a substantially rectangular parallelepiped main body 21 having a hole 22 extending along the center line X, and a convex portion protruding from a lower portion of side surfaces 21a and 21c along a pair of long sides of the main body 21. 23a and 23b are formed integrally with the main body 21 and symmetrically with respect to the center line X. The outer surfaces 23a1, 23b1 of the convex portions 23a and 23b are flush with the side surfaces 21b and 21d along the pair of short sides of the main body 21, and these lower surfaces 23a2 and 23b2 are flush with the bottom surface 21e of the main body 21, respectively. Is. Further, the upper surfaces 23a3 and 23b3 of the convex portions 23a and 23b are inclined surfaces that approach the main body side surfaces 21a and 21c as they go upward, respectively, and have ends in the middle of the main body side surfaces 21a and 21c in the substantially height direction. A female screw 26 for screwing a screw 28, which will be described later, is formed in at least a part of the hole 22 of the main body 21 (FIG. 4).

Square openings (unsigned) are formed above the side surfaces 21b and 21d of the main body, and synthetic resin engaging pieces 24a and 24b, which are generally formed in a triangular shape with a right-angled cross section, are formed in the openings, respectively. It is provided in a state of being urged in a direction of projecting outward by springs 25a and 25b housed in the upper internal space (unsigned) of the above. The lower surfaces 24a1, 24b1 of the engaging pieces 24a and 24b are substantially orthogonal to the main body side surfaces 21b and 21d in a state of being projected by the spring urging. Further, the side surfaces 24a2 and 24b2 are inclined surfaces whose protrusions become smaller toward the upper side.

With reference to FIG. 3, the long side width dimension of the main body 21 of the fixing member 20 (the dimension between the side surfaces 21b and 21d, and the engaging pieces 24a and 24b are inside the main body 21 against the urging force of the springs 25a and 25b. The length of the main body 21 in the state where the engaging pieces 24a and 24b protrude outward due to the urging of the springs 25a and 25b). The side width dimension is A2, the short side width dimension of the main body 21 including the convex portions 23a and 23b (the dimension between the protruding surfaces 23a4 and 23b4 of the convex portions 23a and 23b) is A3, and the diagonal length of the main body 21 is A4. do. In this embodiment, A1 = about 24 mm, A2 = about 30 mm, A3 = about 24 mm, A4 = about 24 mm. Although not shown, the diagonal length A4 is rounded at the lower half of the main body 21 so as to be slightly shorter than the groove width Wa of the front groove 32 of the pillar 30 described later. It should be noted that, for convenience of illustration, the fixing member 20 does not necessarily faithfully reflect the above dimensions throughout the entire drawing, and is shown in a slightly deformed manner.

The fixing member 20 is arranged on the back surface (outer surface) side of the vertical frame 12 via a metal leaf spring 27 having a corrugated cross-sectional shape, and the vertical frame 12 is thickened from the front surface (inner surface) side of the vertical frame 12. It is attached to the vertical frame 12 with a screw 28 screwed into the female screw 26 of the hole 22 of the fixing member main body 21 by sequentially passing through the hole 13 penetrating in the direction and the hole (unsigned) of the leaf spring 27, and the vertical frame 12 (Fig. 6 (a), etc.). The fixing members 20 are attached to the center of the back surface of the vertical frame 12 in the width direction, and an arbitrary number of the fixing members 20 are provided in the height direction thereof. In FIG. 1, two fixing members 20 are used for one vertical frame 12, but the number of the fixing members 20 used is arbitrary, and a larger number of fixing members 20 may be used. A door stop (not shown) for closing a gap between the vertical frame 12 and the vertical frame 12 when the sliding door 2 is closed is fitted in the center of the surface or inner surface of the vertical frame 12 (FIG. 6 (a) above) in the width direction. Since a pair of concave grooves are formed in the height direction (not shown), even if the screw 28 is screwed from the surface side of the vertical frame 12 between the concave grooves, the screw head is hidden by the door stop. It doesn't spoil the appearance.

The leaf spring 27 has a convex shape in the center thereof toward the back surface 21e of the fixing member main body with respect to the back surface or the outer surface (upper view of FIG. 6A) of the vertical frame 12, and both sides thereof are convex toward the back surface of the vertical frame. It is preferable to arrange them so as to have a shape.

In this embodiment, as shown in FIG. 5, the fixing member 20 is detachably fitted to the pillar (attached member) 30 to which the sliding door frame 10 (building member) is fixed over the entire length of the side surface 30a. A concave groove 31 for joint accommodation is formed. The concave groove 31 is composed of a front groove 32 formed so as to go in the vertical direction (column center direction) from the side surface 30a of the pillar 30, and a back groove 33 which is continuously extended in the vertical direction to the back side thereof. Since the groove width Wb of the inner groove 33 is larger than the groove width Wa of the front groove 32, the stepped surfaces 34a and 34b are formed between them. The pillar 30 is a wooden pillar generally used in a wooden building, and a concave groove 31 is formed by cutting one side surface 30a facing inward into a predetermined shape. Alternatively, from the viewpoint of facilitating renovation and remodeling, the pillar 30 may be formed of a lightweight aluminum molded product that has little shape change or dimensional change due to aging and is easy to carry and construct.

The dimensions of the front groove 32 and the back groove 33 will be described in more detail with reference to FIGS. 3 (b) and 3 (c). The groove width Wa of the front groove 32 is the width dimension A1 of the main body 21 of the fixing member 20 itself. , Slightly larger than any of the overall width dimension A3 of the fixing member 20 including the convex portions 23a and 23b and the diagonal length A4 of the main body 21 of the fixing member 20, and the engaging piece 24a by the springs 25a and 25b. , 24b is sufficiently smaller than the overall width dimension A2 in the state of protruding outward. Further, the depth dimension Da of the front groove 32 is substantially equal to the distance H1 from the bottom surface 21e of the main body of the fixing member 20 to the bottom surfaces 24a1, 24b1 of the engaging pieces 24a and 24b in the protruding state. In this embodiment, Wa = about 25 mm and Da = H1 = about 14 mm.

On the other hand, the inner groove 33 has a shape and dimensions that allow the engaging pieces 24a and 24b housed in the inner groove 33 to rotate about the center line X in a state of being projected outward by the springs 25a and 25b. Formed to have. In this embodiment, the inner groove 33 is formed to have a rectangular cross section, and the opening width Wb thereof is formed to be larger than the width dimension A1 of the main body 21 itself. In this embodiment, the engaging pieces 24a and 24b are formed. Is formed to be larger than the overall width dimension A2 in a state in which is projected outward. Further, the depth dimension Db of the depth groove 33 is formed so that the depth (Da + Db) of the entire concave groove 31 is larger than the total height H2 of the fixing member 20. In this embodiment, Wb = about 32 mm, Db = about 10 mm, and H2 = about 23 mm.

Next, with reference to FIG. 6, the work when the sliding door frame 10 is attached to the pillar 30 via the fixing member 20 will be described.

FIG. 6A shows a preparatory stage for mounting work. First, as shown in the upper figure of FIG. 6A, a predetermined number of leaf springs 27 and fixing members 20 are attached in advance to predetermined positions by screws 28 on the back surface 12b of the vertical frame 12 of the sliding door frame 10. The fixing member 20 is oriented so that the engaging pieces 24a and 24b are on the front side, the convex portions 23a and 23b are on the leaf spring 27 side, the main body side surfaces 21a and 21c are on the top and bottom, and the main body side surfaces 21b and 21d are on the left and right sides. It can be installed (sideways). The screw 28 penetrates the holes of the vertical frame 12 and the leaf spring 27 (both are unsigned) and is screwed into the female screw on the inner surface of the hole 22 of the fixing member main body 21, but is loosened to the extent that the leaf spring 27 is not deformed. Leave it in a state.

In this state, the bottom surface 21e of the fixing member main body 21 is not in contact with the leaf spring 27, or even if it is in contact with the leaf spring 27, the leaf spring 27 is not urged. When the screw 28 is turned, the fixing member 20 is also rotated. As a result, the fixing member 20 is set to the rotation angle position or orientation (“second orientation” in the description of the claims) as shown in the lower figure of FIG. 6A. In this direction, the engaging pieces 24a and 24b receive the urging force of the springs 25a and 25b and project outward (laterally) from the side surfaces 21b and 21d of the main body.

From the state shown in FIG. 6A, the vertical frame 12 is brought closer to the pillar 30 and the fixing member 20 is pushed into the concave groove 31 (front groove 32) of the pillar 30. As described above, the groove width Wa of the front groove 32 is substantially the same as or slightly larger than the long side width dimension A1 of the fixing member main body 21 itself, and the engaging pieces 24a and 24b of the main body 21 are in a protruding state. Since it is smaller than the long side width dimension A2, when the fixing member 20 is pushed into the front groove 32, the inclined surfaces 24a2 and 24b2 of the engaging pieces 24a and 24b hit the opening edge of the front groove 32 and urge the springs 25a and 25b. The engaging pieces 24a and 24b are substantially buried in the main body 21 against the above. As a result, as shown in FIG. 6B, the fixing member 20 enters the front groove 32 and further advances.

As it is advanced as it is, as shown in FIG. 6B, the engaging pieces 24a and 24b located at the tip pass through the front groove 32 and enter the inner groove 33. As described above, the long side width dimension A2 of the main body 21 in the state where the engaging pieces 24a and 24b are projected is larger than the groove width Wa of the front groove 32 and smaller than the groove width Wb of the inner groove 33. At the moment when the combined pieces 24a and 24b completely pass through the front groove 32, the engaging pieces 24a and 24b are urged by the springs 25a and 25b so that the engaging pieces 24a and 24b protrude outward and are housed in the inner groove 33. Since the lower surfaces 24a1, 24b1 of the combined pieces 24a and 24b are locked to the stepped surfaces 34a and 34b between the front groove 32 and the inner groove 33, the movement in the direction of being pulled out from the pillar 30 is prevented (FIG. FIG. 6 (c)).

From this state, by tightening the loosened screw 28, the screw 28 is completely screwed into the female screw 26 of the fixing member main body 21, and the work of attaching the vertical frame 12 to the pillar 30 is completed, as shown in FIG. The sliding door frame fixing structure shown is obtained. In this state, since the leaf spring 27 is deformed to give an urging force and is interposed between the vertical frame 12 and the pillar 30, a fixed structure without rattling can be obtained, and the screw 28 is accidentally removed from this state. Prevents loosening. In this mounting work, the fixing member 30 can be fitted into the concave groove 31 with one touch while pressing the vertical frame 12 against the pillar 30, and then the screw 28 only needs to be tightened from the surface side of the vertical frame 12, so that anyone can do this. You can easily work.

As described above, the groove width Wa of the front groove 32 is substantially the same as or slightly larger than the long side width dimension A1 of the fixing member main body 21 itself, and when the fixing member 20 is in this direction, The convex side surfaces 23a2 and 23b2 extending flush with the main body side surfaces 21b and 21d are substantially in contact with the inner surface of the front groove 32 or face each other with a slight gap. Therefore, even if the fixing member 20 is turned in the direction in which the screw 28 is tightened from the state in which the fixing member 20 is housed in the concave groove 31 in the direction shown in the lower figure of FIG. 6 (c) (second direction), the convex portion side surfaces 23a and 23b are stoppers. Therefore, the fixing member 20 does not rotate, and the orientation is maintained substantially the same. That is, the lower figure of FIG. 7 is substantially the same as the lower figure of FIG. In the transition from FIG. 6 (c) to FIG. 7, the screw 28 is tightened while maintaining the orientation (second orientation) of the fixing member 20. Therefore, in the upper diagram of FIG. 7, the screw 28 is the fixing member 20. It is shown that the female screw 26 is completely screwed into the depth of the female screw 26, and the leaf spring 27 is compressed to a substantially flat state accordingly.

Next, with reference to FIGS. 8 and 9, the work of removing the vertical frame 12 attached to the pillar 30 in the fixed structure shown in FIG. 7 will be described.

When the screw 28 is loosened from the fixed state of FIG. 7, the orientation of the fixing member 20 is maintained while the urging force of the leaf spring 27 is working (FIG. 8A), but the urging force is released. Then, the fixing member 20 tries to rotate in the direction of loosening the screw 28 (counterclockwise in the lower figure of FIG. 7). "Turning around" means that when the screw 28 is turned, the fixing member 20 also rotates in the same direction. The convex portions 23a and 23b do not act as stoppers with respect to the rotation in this direction, and as described above, the groove width Wa of the front groove 32 is the diagonal length A4 of the fixing member main body 21. Since it is slightly larger, it allows the fixing member 20 to rotate as the screw 28 is loosened. Therefore, the fixing member 20 goes through the oblique state shown in FIG. 8 (b) and is in the vertical state shown in FIG. 9 (c), that is, the main body side surfaces 21a and 21c are left and right, and the main body side surfaces 21b and 21d are up and down. (The "first orientation" in the description of the claims). As described above, the groove width Wa of the front groove 32 is substantially the same as or slightly larger than the short side width dimension A3 of the main body 21 including the convex portions 23a and 23b, and thus this orientation (first orientation). ), The protruding surfaces 23a4 and 23b4 of the convex portions 23a and 23b of the fixing member 20 are substantially in contact with the inner surface of the front groove 32 or face each other with a slight gap. Therefore, even if the screw 28 is further rotated in the loosening direction, the convex protruding surfaces 23a4 and 23b4 act as stoppers, so that the fixing member 20 does not rotate and the direction shown in the lower figure of FIG. 9C (first). Orientation) is held.

Therefore, by pulling the vertical frame 12 away from the pillar 30 as it is, the fixing member 20 can pass through the front groove 32 (FIG. 9 (d)) and be pulled out (FIG. 9 (e)). Anyone can easily perform this removal work with one touch by pulling out the vertical frame 12 after loosening the screws 28. When the fixing member 20 is in this direction, the engaging pieces 24a and 24b protrude in the vertical direction, so that they do not interfere with the front groove 32 and interfere with the fixing member 20 passing through the front groove 32. Must not be.

An example of the pillar 30 and the concave groove 31 (front groove or opening passage 32 and the inner groove or the inner space 33) formed therein is shown in FIG. 5, but the present invention is not limited to this, and the fixing member 20 described above is not limited thereto. Various embodiments can be adopted as long as the forward / backward and rotation allowed / blocked can be achieved. For example, as shown in FIG. 11, a plate material such as an aluminum plate may be bent to form a pillar 30A having a shape as shown in FIG. In this case, the opening or passage 35 formed on one side surface of the pillar 30A, the large space 36 formed behind the opening, and the bent tip surfaces 37a and 37b of the opening 35 are the pillar 30 of the embodiment shown in FIG. 5, respectively. Corresponds to the front groove 32, the inner groove 33, and the stepped surfaces 34a and 34b in the above.

Further, instead of forming the concave groove 31 and the opening 35 in the columns 30 and 30A themselves, as shown in FIG. 10, a long rail-shaped member 39 created as a separate body from the columns or the skeleton 38 is shown in FIG. It is formed into a shape having a concave groove 31 having substantially the same shape as the concave groove 31 (front groove 32, inner groove 33, stepped surface 34a, 34b) in the pillar 30 of the embodiment shown in 5, and this is formed by a screw or the like to form the skeleton 38. An embodiment fixed to one side surface may be adopted. In this case, the sliding door frame 10 is attached to the skeleton 38 with a gap corresponding to the depth dimension of the rail-shaped member 39.

The present invention is not limited to the illustrated embodiments described in detail above, and can be variously modified and implemented within the scope of the invention described in the claims. For example, in the illustrated embodiment, the leaf spring 28 is interposed between the building member and the member to be attached, and it functions effectively in obtaining a strong attachment state without rattling, but even if this is omitted. Since the action of allowing / blocking the rotation of the fixing member according to the present invention is similarly exerted, the embodiment in which the leaf spring 28 is not interposed is also within the scope of the present invention.

For example, in the illustrated embodiment, the pair of engaging pieces 24a and 24b are provided in the fixing member 20 so as to be buried in the main body 21 via the springs 25a and 25b. The engaging pieces 24a and 24b protruding outward may be fixedly provided to the main body 21. In this case, as shown in the illustrated embodiment, the fixing member 20 is inserted into the front groove 32 against the urging force of the springs 25a and 25b while keeping the fixing member 20 in the second orientation (FIGS. 6A to 6C). However, the fixing member 20 is inserted into the front groove 32 in a direction in which the fixed engaging pieces 24a and 24b do not interfere with the front groove 32 (the first direction, FIGS. 9C to 9e). By accommodating the engaging pieces 24a and 24b in the inner groove 33 and then rotating the screw 28 by about 90 degrees in the tightening direction, the fixed structure shown in FIG. 7 can be obtained in the second direction. In the case of this embodiment, it cannot be attached by one-touch work as in the illustrated embodiment, but it can be attached by a simple two-step operation of pushing it into the front groove 32 and then turning the screw 28, so that no skill is required. The removal operation described with reference to FIG. 9 can be performed in the same manner as in the illustrated embodiment.
