  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In this specification and the description of the claims, the front surface side of the wall where the rail support bracket 1 is provided is defined as the front, the rear surface side of the wall where the studs 62 are provided is defined as the rear.

  First, a schematic basic configuration of a rail support bracket 1 (hereinafter, simply referred to as a bracket 1) according to the present embodiment will be described with reference to FIGS.

  This bracket 1 is a rail supporting bracket 1 for hanging and supporting a rail member 3 having a strip-shaped substrate portion 3a on the upper surface side at a plurality of places in front of a wall surface 61. The bracket 1 includes a front member 10 disposed in front of a wall surface 61 and a rear member 20 disposed between the front member 10 and the wall surface 61. The front member 10 has a front clamping piece 12, while the rear member 20 has a rear clamping piece 22.

  The front member 10 and the rear member 20 are connected and fixed to each other, and in a state where the rear member 20 is fixed to a structure (for example, the stud 62) on the wall surface 61 side, the front holding piece 12 and the rear holding piece 22 are fixed. Thus, the board member 3a is sandwiched from the front-back direction to support the rail member 3.

  According to such a bracket 1, the rail member 3 has a structure in which the rail member 3 is hung and supported, so that it is not necessary to fix the rail member 3 to the bracket 1 with a fixture, and labor can be saved. In addition, since there is no need to provide a hole for a fixture to be fixed to the bracket 1 on the rail member 3 at a construction site or the like, the construction of the rail device A including the rail member 3 and the bracket 1 can be shortened. And efficiency can be improved.

  Next, the detailed configuration of the bracket 1 and the rail member 3 supported by the bracket 1 will be described with reference to the drawings.

  FIG. 1A is an overall perspective view of the bracket 1 in a state where two members constituting the bracket 1 are connected and fixed. FIG. 1B is a side view of the same, and FIG. 1C is a side view of the bracket 1 in a state where two members are temporarily connected. FIG. 2 is a front view of a wall surface 61 showing an attachment target of the bracket 1. FIG. 3A is a schematic partial enlarged plan view of a main part of the connection of the bracket 1, and FIGS. 3B and 3C are perspective views on the rear side showing a procedure of combining the bracket 1.

  The rail device A is attached to the front of the wall surface 61 as shown in FIG. Therefore, the bracket 1 is attached and fixed to a structure on the wall surface 61 side (a stud 62 arranged behind the wall surface 61 in the illustrated example) via a wall panel. As shown in FIG. 2, the brackets 1 are attached to a plurality of locations (five locations marked with x in the figure), and the rail members 3 are supported by them. A sliding door 70 (not shown in FIG. 2; see FIG. 8) is suspended from the rail member 3. The sliding movement of the sliding door 70 along the rail member 3 opens and closes the opening formed on the wall and formed by the frame. Thus, this sliding door 70 is constructed as an outset sliding door.

  The rail member 3 supported by the bracket 1 has a board portion 3a on the upper side and a rail main body portion 3b on the lower side, as shown by a two-dot chain line in FIGS. 1B and 1C. Have been. Incidentally, these two parts constituting the rail member 3 are formed by connecting and fixing the rail base 30 and the upper rail 40 which are separate from each other, the details of which will be described later in the description of FIGS. Now, a schematic configuration of the board portion 3a related to the sandwiching structure by the bracket 1 will be described.

  The board portion 3a has an engaging portion 32 extending in a stepped manner on the front end side of the plate-shaped main body portion 31 and has a fitting portion 33 extending vertically up and down on the rear end side of the main body portion 31. It becomes. The board portion 3a is in a state in which the engaging portion 32 and the fitting portion 33 are engaged and fitted by the bracket 1, and the board portion 3a is sandwiched in the front-rear direction (the front of the engaging portion 32 and the rear of the fitting portion 33). It is designed to be suspended from above.

  On the other hand, the bracket 1 is attached to the wall surface 61 in a state where the two members constituting them are united as shown in FIGS. 1 (a) and 1 (b). 1A is an arrow indicating a direction from the front to the rear of the wall surface 61. When viewed from that direction, both members have a generally symmetrical shape.

  Both the front member 10 and the rear member 20 of the present embodiment are formed by processing a plate made of a metal material such as stainless steel.

  The front member 10 has a shape having a front main body 11 in which a front sandwiching piece 12 is arranged on the front side, and a front erecting piece 13 standing up from the rear of the front main body 11. The front standing pieces 13 are formed at both side ends, respectively, and each front standing piece 13 is provided with a fixture insertion hole 13a. In addition, the front holding piece 12 has a support piece 12 a that extends downward and rearward from the front end of the front body 11.

  Further, as shown in FIGS. 1A and 3B, a front main body 11 extends rearward between both front standing pieces 13. As shown in FIGS. 3A and 3B, each of the two rear ends of the front main body 11 has a hook piece formed of a protruding piece protruding laterally so as to be parallel to the front standing piece 13. 14 are formed.

  The rear member 20 has a shape having a rear main body portion 21 in which a rear holding piece portion 22 is arranged on the rear side, and a rear erecting piece 23 standing upright from a front portion of the rear main body portion 21. The rear upright piece 23 is formed at each side end so as to face the front upright piece 13 in the front-rear direction, and each rear upright piece 23 is provided with a fastener screw hole 23a. In this example, a bolt 18 is used as a fixing tool, and a female screw corresponding to the bolt 18 is formed in the fixing screw hole 23a. Of course, a configuration in which the nut 18 is screwed with a separate nut may be used. In this case, the fixing hole 23a may be a bolt insertion hole in which a female screw is not formed.

  Further, an upper fixing piece 24 and a lower fixing piece 25 that are attached to the wall surface 61 and fixed to the stud 62 are formed to extend vertically from the rear part of the rear main body 21. The upper fixing piece 24 and the lower fixing piece 25 are provided with screw insertion holes 24a and 25a for attaching to the wall surface 61 with screws (not shown). Further, projecting pieces 26 projecting forward are formed on both side ends of the lower fixing piece 25.

  As described above, the front member 10 and the rear member 20 are fixed by the fixing tool such as the bolt 18 in a state where the front standing piece 13 and the rear standing piece 23 face each other (FIG. 1). (See (a) and (b)). Then, the rail member 3 is suspended and supported by the two members thus connected and fixed (see FIG. 1B).

  Specifically, the front holding piece 12 has an engagement recess 12b formed by a front portion of the front body 11 of the front member 10 and a support piece 12a. The engaging portion 32 of the substrate portion 3a engages with the engaging concave portion 12b. On the other hand, the rear holding piece 22 has a fitting concave portion 27 formed by a rear portion of the rear main body 21 of the rear member 20, a lower fixing piece 25, and a projecting piece 26. The fitting portion 33 of the substrate 3a fits into the fitting recess 27. In this way, the board member 3a is sandwiched and supported by the front member 10 and the rear member 20 in the front-rear direction.

  More specifically, in the bracket 1, the front holding piece 12 has a support piece 12a, and the rear holding piece 22 has a protruding piece 26. The support piece 12a lowers the front end of the substrate 3a. And the rear end of the substrate portion 3a is supported by the protruding pieces 26 from below. That is, the bracket 1 does not have a simple holding structure, but has an engaging and fitting structure at the front and rear ends so that the rail member 3 cannot drop. In particular, since the support piece 12a bent rearward is formed on the front end side of the front member 10, the fitting portion 33 of the board portion 3a is firmly fitted and held by the fitting concave portion 27 of the rear holding piece portion 22. In this case, there is almost no possibility that the rail member 3 will fall even when the bracket 1 is in the temporary connection state.

  By the way, since the support piece 12a of the front member 10 and the protruding piece 26 of the rear member 20 protrude so as to substantially face each other in the front-rear direction, the rail member 3 is attached to the bracket 1 in the state of FIG. It cannot be easily mounted simply by moving it upward. Therefore, the worker may mount the rail member 3 with the rail member 3 tilted forward or backward. However, the front member 10 and the rear member 20 are temporarily connected (temporarily fixed) as shown in FIG. Then, the rail member 3 may be mounted.

  FIG. 1C shows a temporary connection state in which the bolt 18 inserted from the front of the front standing piece 13 is loosely screwed into the fixing hole 23 a of the rear standing piece 23. Because of the temporary connection, the front member 10 can be moved in the front-rear direction, and by pulling the front member 10 forward, the gap S between the standing pieces is wider than in the state of FIG. The space between the protruding pieces 26 also expands. Therefore, the board portion 3a of the rail member 3 is easily mounted between the front holding piece 12 and the rear holding piece 22.

  Further, if the upright pieces are separated from each other, the front member 10 can be rotated to an upper position as shown by a two-dot chain line in FIG. If the front member 10 is rotated to the position indicated by the two-dot chain line, the board portion 3a is more easily mounted.

  Specifically, first, the fitting portion 33 of the board portion 3a is inserted and fitted into the fitting recess 27 of the rear member 20. Next, the front holding portion 12 of the front member 10 is slightly lifted and rotated to a position indicated by a two-dot chain line, so that the substrate 3a is brought into a substantially horizontal state. Then, the front holding piece portion 12 is returned to the original position, and the engaging portion 32 is hooked by the support piece 12a. Such a temporary connection operation is performed on all the brackets 1 to temporarily hold the rail member 3, and the rail member 3 is slid and adjusted to determine the position. 20 may be permanently fixed.

  The increase in the gap S between the standing pieces shown in FIGS. 1B and 1C is limited by the distance between the front standing piece 13 and the hook piece 14 arranged behind the front standing piece 13. When the front standing piece 13 and the rear standing piece 23 are fixed as shown in FIGS. 1B and 3C and FIG. 21 is a protruding piece arranged in the vicinity of the corner at the entrance. In the united state of the members, the rear upright piece 23 is disposed between the front upright piece 13 and the hooking piece 14, as shown in the main part schematic plan view of FIG.

  Since the hook piece 14 is formed on the front member 10 in this manner, the movable amount of the front member 10 in the front-rear direction is determined by the gap L1 between the front standing piece 13 and the rear standing piece 23 and the rear standing piece 23, This is equivalent to the total dimension of the gap dimension L2 between the hook pieces 14 (see FIG. 3A). That is, the movable amount of the front member 10 in the front-rear direction is determined by the distance L3 between the front standing piece 13 and the hooking piece 14 and the thickness L4 of the rear standing piece 23.

  As described above, since the front member 10 has the hook pieces 14, the movement in the front-rear direction is restricted, and even when the front member 10 is not connected with the bolt 18, the pull-out movement of the front member 10 is regulated, and thereby the front member during operation is 10 can be prevented from coming off.

  Further, when the two members are united without being temporarily connected by the bolt 18, the front member 10 is hung on the rear member 20 by the hooking pieces 14. However, as shown in FIG. 3A, since the rear upright piece 23 is disposed between the front upright piece 13 and the hooking piece 14, the front member 10 can be held in a state where the front upright piece 13 is almost upright. Therefore, even when the temporary connection by the bolts 18 is not performed, the work of mounting the rail member 3 on the bracket 1 of the board portion 3a can be performed.

  In addition, as shown in FIG. 3A, the hook pieces 14 of the present example protrude in directions away from each other (left and right directions when viewed from the front), and they are separated from the rear body 21 of the rear member 20. It is arranged on the top. Therefore, as shown in FIGS. 3B and 3C, both members can be combined by moving the front member 10 from above to below the rear member 20.

  In this manner, once the front member 10 is combined with the rear member 20, the movement of the front member 10 in the left-right direction as well as in the front-rear direction is restricted. Of course, there is no possibility that the front member 10 falls in that state. That is, the front member 10 cannot be removed unless the front member 10 is lifted up in the reverse order of FIGS. 3B and 3C. Therefore, after the front member 10 is combined with the rear member 20, it can be left in a hand-free state, which facilitates the work of attaching the rail member 3.

  As described above, the rail member 3 can be easily attached to the plurality of brackets 1 attached to the wall surface 61. Further, as described above, since the board portion 3a of the rail member 3 has a support structure sandwiched by the bracket 1, the rail member 3 does not need to be screwed to the bracket 1. Furthermore, since there is no need to drill holes for screwing, the construction work can be performed more quickly. In addition, since no drilling is performed, no processing waste can be generated, and labor for cleaning can be saved.

  Further, since the bracket 1 is not adapted to the length of the rail member 3 and is adapted to support the rail member 3 with a plurality of members, the bracket 1 may be attached to an appropriate place. Since it can be attached to the stud 62 (see FIG. 2) as in the present embodiment, there is no need to reinforce the foundation, and the efficiency of construction can be improved. In addition, since the bracket 1 is not long, it saves material costs and is easy to handle.

  Next, the detailed configuration of the rail member 3 and the relationship between the rail member 3 and the bracket 1 will be described with reference to FIGS.

  The rail member 3 has an elongated shape as shown in FIG. The rail member 3 is configured such that the board portion 3a disposed on the rail member 3 is suspended and supported by the bracket 1 at a plurality of appropriate positions.

  FIG. 4 is a partially exploded perspective view of the rail device A including the bracket 1. As shown in FIG. 4, the rail member 3 is configured by connecting two members, that is, a rail base 30 forming the board portion 3a and an upper rail 40 forming the rail main body portion 3b. In this connection, the connecting member 50 is attached to a notch long hole 34 formed at a proper position of the rail member 3 in a direction orthogonal to the longitudinal direction, and the connecting member 50 and the upper rail 40 are connected to a stopper 56 (e.g., a screw). This is done by fixing the position as shown in FIG. The connecting member 50 is a member that can be fixed after adjusting the relative positional relationship between the rail base 30 and the upper rail 40 in the front-rear direction. The connection member 50 will be described later in the description of FIG.

  Further, a stopper member 46 for preventing the runner member 71 guided by the upper rail 40 from dropping from the upper rail 40 is attached to the longitudinal end of the upper rail 40. The stopper member 46 is fixedly held at the end of the upper rail 40 by cooperation with a screw nut 47 similarly mounted on the upper rail 40.

  FIG. 5 is a partial perspective view of the rail device A in which such a rail member 3 is correctly attached to the bracket 1 by the procedure described with reference to FIGS. As shown in this figure, the bracket 1 firmly holds the rail base 30 of the rail member 3 between the front member 10 and the rear member 20.

  FIG. 6 is an enlarged sectional view corresponding to line XX in FIG. As shown in FIG. 6, the upper rail 40 has a configuration having a connecting portion 41 that is connected to the lower surface of the rail base 30 and connected thereto, and a runner holding portion 43 disposed below the connecting portion 41. Is done.

  The connection part 41 is a part for connecting the upper rail 40 to the rail base 30. The connecting portion 41 has a housing space 41a in which a head 56a of a stopper 56 for connection is housed. The stopper 56 is inserted from below through the insertion opening 42, passes through the cutout elongated hole 34 formed in the rail base 30 (see FIG. 5), and the nut piece 51 of the connecting member 50 attached to the rail base 30. Is screwed to the female screw portion 51a. Thus, the upper rail 40 is fixed to the rail base 30.

  The runner holding portion 43 is a portion having a rail space for disposing the roller portion 72 of the runner member 71 provided to protrude from the upper end of the sliding door 70. The runner holding portion 43 includes an upper plate portion 43a, a front surface portion 43b hanging down from a front end of the upper plate portion 43a, and a rear surface portion 43d hanging down from a rear end of the upper plate portion 43a.

  The runner holding portion 43 further includes roller guide pieces 43c and 43e protruding over the entire length in the longitudinal direction of the upper rail 40 so that the front ends face each other at the lower ends of the front surface portion 43b and the rear surface portion 43d. The roller portion 72 of the runner member 71 is disposed in a rail space surrounded by the upper plate portion 43a, the front surface portion 43b, the rear surface portion 43d, and both roller guide pieces 43c and 43e.

  The stopper member 46 described above is attached to the longitudinal end of the rail space, and a screw nut 47 is attached to the housing space 41a of the connecting portion 41. A screw (not shown) inserted from below the stopper member 46 through a slit 43aa provided in the upper plate portion 43a is screwed into the screw holding nut 47, and both members are fixed so as to sandwich the upper plate portion 43a. It is supposed to be.

  Further, above the front surface 43b of the runner holding portion 43, a curtain plate piece 44 is formed over the entire length of the upper rail 40 in the longitudinal direction so that the front surface exposed forward is flush. The bracket 1 is covered and hidden by the curtain plate piece 44 so that the bracket 1 cannot be seen from the front.

  Although the curtain plate piece 44 shown in FIG. 6 is formed integrally with the runner holding portion 43, it may be a separate member, for example, a thin plate material that can be mounted so as to overlap the front portion 43 b of the runner holding portion 53. You may comprise a curtain piece.

  When the curtain plate piece 44 is formed integrally with the runner holding portion 43, the number of parts can be reduced and the manufacturing cost can be reduced. Further, in the case of a separate curtain plate piece, the work of attaching the rail member 3 (such as the work of fixing the bolt 18) is facilitated, which leads to more efficient construction.

  A projecting piece 45 is formed on the rear surface 43 d of the runner holding portion 43 so as to project rearward over the entire length of the upper rail 40 in the longitudinal direction. The protruding piece 45 determines the position of the upper rail 40 in the front-rear direction by contacting its front end (rear end) with the front surface of the frame 63. In other words, depending on how the frame portion 63 protrudes from the wall surface 61, the positional relationship between the rail base 30 and the upper rail 40 in the front-rear direction is adjusted by the connecting member 50 as described later, and as shown in FIG. What is necessary is just to make the piece 45 contact | abut the frame part 63.

  Next, the adjustment of the front-rear position between the rail base 30 and the upper rail 40 by the connecting member 50 will be described with reference to FIGS.

  As shown in FIG. 7A, the connecting member 50 is provided in the nut piece portion 51 having the female screw portion 51a, the lower piece portion 52, the upper piece portion 53, and the cutout elongated hole 34 of the rail base 30. And an insertion piece 54 that is inserted along it. Each of the nut piece 51, the lower piece 52, and the upper piece 53 is orthogonal to the insertion piece 54 in a plan view, and has a shape of a wing piece extending to both sides around the insertion piece 54. You.

  As shown in FIG. 7B, the connecting member 50 has an upper piece 53 and a nut piece 51 arranged along the upper surface of the rail base 30, and a lower piece 52 arranged along the lower surface of the rail base 30. Is mounted in the cutout elongated hole 34 of the rail base 30 (see also FIG. 6).

  Since the connecting member 50 has such a configuration and shape, when the connecting member 50 is attached to the cutout elongated hole 34 of the rail base 30, the swinging of the connecting member 50 itself is avoided, and the connecting member 50 extends along the cutout elongated hole 34. Only the forward and backward sliding movements are allowed.

  The connecting member 50 can arrange the position of the female screw portion 51a of the nut piece portion 51 at an appropriate position while being slid along the notch long hole 34. In other words, the nut piece 51 of the connecting member 50 integrated with the rail base 30 and the connecting portion 41 of the upper rail 40 are vertically aligned, so that the front and rear directions of the upper rail 40 with respect to the rail base 30 (FIG. The relative position of the white arrow in b) can be determined. Then, the fastener 56 (see FIG. 6) inserted from below the connecting portion 41 is screwed into the female screw portion 51a of the nut piece portion 51, so that the rail base 30 and the upper rail 40 are connected and fixed at the determined relative position. Is done.

  If the connecting portion 41 of the upper rail 40 is fixed to the nut piece portion 51, the claw pieces 51b provided on the nut piece portion 51 bite into the upper surface of the rail base 30, so that the cutout elongated holes 34 of the connecting member 50 thereafter. The slide movement along is restricted.

  The rail member 3 in which the relative positional relationship between the rail base 30 and the upper rail 40 is determined as described above is attached to the plurality of brackets 1 attached to the wall surface 61 in the procedure described above.

  The front and rear width dimensions of the rail member 3 are variously adjusted by the above-described adjustment. However, since the front and rear width dimensions of the rail base 30 are constant, the front and rear width dimensions of the rail member 3 are variously changed to perform construction. In such a case, there is no need to prepare the bracket 1 having a size corresponding to the size. That is, as long as the rail base 30 having the same shape and the same front-rear width dimension is used, the same bracket 1 is used even when the relative position of the upper rail 40 to the rail base 30 is different or the shape and dimensions of the upper rail 40 are different. can do.

  The runner member 71 of the sliding door 70 is mounted on the rail member 3 attached as described above, and the sliding door 70 itself is also suspended and supported. FIG. 8 is a front view of the outset sliding door constructed in this manner. At the lower end of the sliding door 70, a guide groove 73 that opens toward the floor surface is formed along the width direction of the sliding door 70. A fixing pin 65 fixed to the floor is loosely inserted into the guide groove 73 to guide movement of the sliding door 70 in the opening and closing direction.

  Since the outset door device B described above uses the rail device A including the bracket 1 as illustrated in FIG. 1, the construction of the entire outset door device B can be efficiently performed.

  Although the outset sliding door has been described as an example, it is needless to say that the outset folding door can be constructed using the bracket 1 and the rail device A without being limited to the sliding door 70.
