Description

The present invention relates to a regulating unit for regulating upward movement of a sliding door shoji, fittings, and a method for attaching the regulating unit.

Sliding door shoji have traditionally been built into a frame with rails using a method called kendon. Specifically, for example, first insert the sliding door shoji from the front of the frame into the groove of the upper frame with the upper end in front of the lower end, and then insert the lower end onto the rail of the lower frame. Move and place the sliding door shoji in an almost vertical position. At this time, the sliding door shoji is placed at a higher position than the position where it is supported by the rails. Next, the sliding door shoji is lowered onto the rail, and the sliding door shoji is supported by the rail.

At this time, the width in the vertical direction between the upper end of the rail of the lower frame supporting the sliding door shoji and the lower end of the sliding door shoji (hereinafter referred to as the overlapping width with the rail of the sliding door shoji) is the width of the width before the sliding door shoji is lowered. Narrower than the distance between the bottom edge of the frame rail and the top edge of the sliding door shoji. Therefore, if the sliding door shoji lifts off the rail due to an operation such as closing the sliding door shoji in a hurry, there is a risk that the sliding door shoji will come off the rail. For this reason, conventionally, for example, as in Patent Document 1, in order to prevent the sliding door shoji from falling off, an outer retaining piece that is fitted into the frame above the sliding door shoji after the sliding door shoji is built into the frame has been known. It is being

Japanese Patent Application Publication No. 11-107613

Even if the sliding door shoji installed by Kendon lifts off the rail, in order to prevent the sliding door shoji from coming off the rail, it is necessary to use a regulating member that restricts the upward movement of the sliding door shoji, such as the conventional outer stopper mentioned above. The distance between the sliding door shoji and the top edge of the sliding door shoji must be narrower than the overlap between the sliding door shoji and the rail. To place the regulating member at the appropriate position relative to the top edge of the sliding door shoji, for example, attach the regulating member, move the sliding door shoji under the regulating member, and check the distance between the regulating member and the top edge of the sliding door shoji. However, if the sliding door shoji comes off, move the sliding door shoji, remove the regulating member, interpose a thin plate between it and the frame, move the sliding door shoji again under the regulating member, and remove the regulating member and the sliding door shoji. There is a problem in that the work is complicated because the work of checking the distance from the top edge of the workpiece must be repeated.

The present invention has been made in view of such problems, and its object is to provide a regulating unit that regulates the upward movement of a sliding door shoji, which can be easily placed in an appropriate position, and a regulating unit that is equipped with this regulating unit. The object of the present invention is to provide fittings and a method for installing the regulating unit.

In order to achieve such an object, the regulation unit of the present invention has an opposing part that faces the upper end of the door edge side of the sliding door shoji with an interval in the vertical direction, and a regulation unit that regulates the upward movement of the sliding door shoji. and a holding member that is fixed to a frame body on which the sliding door shoji is supported and that can hold the regulating member in either a movable state or an immovable state, The holding member includes a guide portion in which the opposing portion can guide the regulating member that moves toward the door frame from a position lower than the upper end of the sliding door shoji to a position higher than the upper end. It is characterized by having.

The distance between the pair of frame wall portions 70h is wider than the outer diameter of the head 73a of the screw 73. The lower surface of the upper multi-stage sloped part 70e of the regulating member is exposed between the pair of frame wall parts, and the lower surface also has a plurality of flat parts 70p and sloped parts 70q like the upper surface. The flat portion 70p of the lower surface corresponds to a screw contact portion. The lower ends of the pair of frame wall portions 70h have a step-like shape rising toward the door edge, and a plurality of adjacent lower flat portions 70i are connected at a certain step H1. This step H1 is the same as the step H1 of the holding member multi-step inclined portion 72h and the upper regulating member multi-step inclined portion 70e.

The step H1 at the lower end of the holding member multi-step inclined portion 72h, the upper regulating member multi-step inclined portion 70e, and the frame wall portion 70h is located above the lower end 3b of the sliding door shoji 3 when the sliding door shoji 3 is supported by the lower rail 4b. It is set lower than the height H2 (FIG. 2) to the upper end of the lower rail 4b protruding from the lower rail 4b.

As shown in FIG. 8, in the second portion 70b of the regulating member 70, an elongated insertion hole 70j into which the screw 73 is inserted is provided at the center in the viewing direction along the sliding direction. The long insertion hole 70j has a narrow portion 70l having a width narrower than the inner diameter of the round hole portion 70k so that the plurality of round hole portions 70k provided at intervals in the sliding direction connect the centers of the round hole portions 70k. It has a connected shape. The inner diameter of the round hole 70k is slightly larger than the outer diameter of the threaded portion 73b of the screw 73, and the width of the narrow portion 70l is slightly smaller than the outer diameter of the threaded portion 73b of the screw 73. That is, the round hole portion 70k corresponds to the widened portion.

Therefore, when the screw 73 inserted through the long insertion hole 70j of the regulating member 70 and the insertion hole 72k of the holding member main body 72 and screwed into the plate nut 74 of the holding member 71 is loosely tightened, the regulating member 70 slides. move in the direction. At this time, when the regulating member 70 slides and the screw 73 passes through the narrow portion 70l between the adjacent round holes 70k, a light frictional load is generated.
Further, the second portion 70b of the regulating member 70 is provided with a protrusion 70m that protrudes toward the bathroom side, has a cylindrical shape, and is inserted into the annular protrusion 72n of the holding member main body 72.

The regulation unit 7 of this embodiment positions the regulation member 70 in a state where the regulation member 70 is temporarily held by the screw 73 on the holding member main body 72 fixed to the frame body 4 via the fixing member 8, The regulating member 70 is fixed to the holding member main body 72 by tightening the screw 73. In the regulating member 70 temporarily held by the holding member main body 72, the protrusion 70m is inserted inside the annular protrusion 72n, and the multi-stage inclined part 70e on the regulating member of the first portion 70a is connected to the changing room side portion of the holding member 71. The upper regulating member multi-stage inclined part 70e of the second part 70b vertically faces the holding member multi-stage inclined part 72h at the bathroom-side part 72e of the holding member 71. , is pressed upward by the spring portion 72g.

In the temporarily held state, the screw 73 is loosely tightened, so the regulating member 70 can move in the sliding direction while being guided by the annular protrusion 72n and the holding member multi-stage inclined part 72h. The annular protrusion 72n and the holding member multi-stage inclined part 72h are both shaped to rise stepwise toward the left vertical frame 43 side, so that they are guided by the annular protrusion 72n and the holding member multi-stage inclined part 72h. When the regulating member 70 is located on the rightmost side, the lower surface 70f of the first portion 70a is placed at the lowest position, and when the regulating member 70 is moved to the leftmost side, the lower surface 70f of the first portion 70a is placed at the highest position. Ru. The regulation unit 7 is lower than the upper end 3a of the sliding door shoji 3 when the lower surface 70f of the first portion 70a is the lowest, and higher than the upper end 3a of the sliding door shoji 3 when the lower surface 70f of the first portion 70a is the highest. It is configured to be.

To attach the regulating member 70, first, open the sliding door shoji 3 and place it on the right side of the regulating unit 7. At this time, the holding member 71, in which the regulating member is temporarily held movably, is fixed via the fixing member 8 (holding member fixing step and regulating member holding step). The regulating member 70 temporarily held by the holding member 71 is placed on the rightmost side.

Next, slide the sliding door shoji 3 in the closing direction, that is, in the direction toward the left vertical frame. At this time, as shown in FIG. 9(a), the door tip of the sliding door shoji 3 comes into contact with the right end 70n of the regulating member 70 located on the rightmost side, and the sliding door shoji 3 is further moved in the closing direction, thereby regulating the regulation member 70. The member 70 moves to the left together with the sliding door shoji 3 (regulating member moving step). In the rightmost position, the regulating member flat part 70c of the regulating member 70 and the guide flat part 72i of the holding member main body 72 face each other, and the regulating member inclined part 70d of the regulating member 70 and the guide of the holding member main body 72 face each other. The inclined portion 72j is opposed to the inclined portion 72j. Further, the screw 73 is located in the round hole portion 70k of the long insertion hole 70j.

When the regulating member 70 moves to the left side together with the sliding door shoji 3, first, the regulating member flat portion 70c of the regulating member 70 moves while sliding along the guide flat portion 72i of the holding member main body 72, and the regulating member 70 When the regulating member flat part 70c passes over the guide flat part 72i of the holding member main body 72, the regulating member inclined part 70d of the regulating member 70 moves while sliding along the guide inclined part 72j of the holding member main body 72. As the regulating member inclined portion 70d of the regulating member 70 moves along the guide inclined portion 72j of the holding member main body 72, the regulating member 70 moves leftward while rising.

Then, the regulating member inclined part 70d of the regulating member 70 crosses the guide inclined part 72j of the holding member main body 72, and the regulating member flat part 70c of the regulating member 70 faces and abuts against the guide flat part 72i of the holding member main body 72. As a result, the lower surface 70f of the first portion 70a of the regulating member 70 moves to a position higher than the step H1 of the holding member multi-step inclined portion 72h. While the regulating member 70 rises by the step H1, the long insertion hole 70j is located at the adjacent round hole 70k, where the screw 73 passes through the narrow portion 70l from the round hole 70k.

When the regulating member 70 rises by the step H1, as shown in FIG. 9(b), if the lower surface 70f of the first portion 70a of the regulating member 70 is located above the upper end 3a of the sliding door shoji 3, Since the regulating member 70 is separated from the sliding door shoji 3, when the sliding door shoji 3 continues to slide, only the sliding door shoji 3 moves. In this state, as shown in FIG. 9(c), slide the sliding door shoji 3 to the right, tighten the screws 73, and fix the regulating member 70 as shown in FIG. 9(d). step).

Further, when the regulating member 70 rises by the step H1, if the lower surface 70f of the first portion 70a of the regulating member 70 is located below the upper end 3a of the sliding door shoji 3, the sliding door shoji 3 is further restricted. It slides to the left together with the member 70, and the regulating member 70 further raises the step H1. In this way, by sliding the sliding door shoji 3 in the tightening direction, the regulating member 70 is moved together with the sliding door shoji 3, and the lower surface 70f of the first portion 70a is moved above the upper end 3a of the sliding door shoji 3. and tighten the screw 73 to fix the regulating member 70.

In this way, by sliding the sliding door shoji 3 in the closing direction, the regulating member 70 moves together with the sliding door shoji 3 such that the lower surface 70f of the first portion 70a of the regulating member 70 is lower than the upper end 3a of the sliding door shoji 3. Even if the lower surface 70f of the first portion 70a moves to a position higher than the upper end 3a of the sliding door 3 by rising from this state by a step H1, the lower surface 70f of the first portion 70a The distance from the upper end 3a of the sliding door shoji 3 is narrower than the height of the step H1. The step H1 of the holding member multi-step inclined portion 72h is set lower than the height H2 to the upper end of the lower rail 4b that protrudes upward from the lower end 3b of the sliding door shoji 3 supported by the lower rail 4b. The member 70 is arranged at a position where the sliding door shoji 3 is difficult to come off the lower rail 4b.

According to the regulation unit 7 of this embodiment, the holding member 71 capable of holding the regulation member 70 holds the regulation member 70 moving toward the left vertical frame 43 so as to face the upper end 3a of the sliding door shoji 3 on the door edge side. Since the lower surface 70f of the first portion 70a of the regulating member 70 has a holding member multi-stage inclined portion 72h that can be guided from a position lower than the upper end 3a of the sliding door shoji 3 to a position higher than the upper end 3a, the sliding door shoji 3 can be moved easily. When the lower surface 70f of the first part 70a is located below the lower end 3b of the sliding door shoji 3 in the open state, when the sliding door shoji 3 is slid toward the left vertical frame 43, the door edge of the sliding door shoji 3 will touch the regulating member. 70. Then, when the sliding door shoji 3 is further slid toward the left vertical frame 43, the regulating member 70 moves toward the left vertical frame 43 together with the sliding door shoji 3, and also moves upward guided by the holding member multi-stage inclined portion 72h.

When the lower surface 70f of the first portion 70a moves above the sliding door shoji 3, the regulating member 70 stops moving and the sliding door shoji 3 continues to slide. At this time, the sliding door shoji 3 is stopped, and the restriction member 70 is held by the holding member 71 with an appropriate distance from the upper end 3a of the sliding door shoji 3 based on the position where the restriction member 70 has stopped. It is possible to easily arrange the member 70 at an appropriate position to restrict upward movement of the sliding door shoji 3.

Further, the step H1 of the holding member multi-step inclined portion 72h of the holding member main body 72 and the step H1 of the regulating member inclined portion 70d facing the holding member multi-step inclined portion 72h in the regulating member 70 are supported by the lower rail 4b. Since the height H2 is lower than the height H2 from the lower end 3b of the sliding door shoji 3 to the upper end 4c of the lower rail 4b that protrudes upward from the lower end 3b, even if the sliding door shoji 3 rises, the lower end 3b of the sliding door shoji 3 will be lowered. It does not move above the upper end 4c of the rail 4b. Therefore, it is possible to more reliably prevent the sliding door shoji 3 from falling off the lower rail 4b.

Further, since the regulating member 70 is held by a screw 73 on the holding member main body 72 having the holding member multi-stage inclined portion 72h of the holding member 71, the regulating member 70 can be tightened or loosened by tightening or loosening the screw 73. can be easily held in either a movable or immovable state.

Further, a long insertion hole 70j provided in the regulating member 70 through which a screw 73 that immovably holds the regulating member 70 to the holding member 71 is inserted is long in the direction of movement of the regulating member 70, and the threads of the screws 73 are inserted in each stage. Since it has a round hole part 70k that is wider than the outer diameter of the part 73b, and a narrow part 70l that is narrower than the outer diameter of the threaded part 73b is provided between the adjacent round hole parts 70k, the regulating member 70 moves, and when the narrow part 70l of the long insertion hole 70j passes the position of the screw 73, it becomes difficult to move, but when it passes through the narrow part 70l and reaches the round hole part 70k, it moves smoothly. and stabilize. Since the round hole portion 70k is provided in each step, the regulating member 70 moves and easily stops moving when the screw 73 is located in the round hole portion 70k, that is, the step, so the screw 73 easily stops stably. It is possible to easily arrange the regulating member 70 at the position.

Further, the first part 70a side, where the lower surface 70f forms the opposing part, faces the upper end 3a of the sliding door shoji 3, and the second part 70b side, which has the lower flat part 70i under the regulating member inclined part 70d, is fixed to the holding member main body 72. Therefore, it is possible to securely fix the sliding door shoji 3 to the holding member main body 72 on the second portion 70b side and restrict the upward movement of the sliding door shoji 3 on the first portion 70a side.

Furthermore, it is possible to provide the fitting 1 in which the regulating member 70 can be easily placed at an appropriate position to regulate the upward movement of the sliding door shoji 3.

Furthermore, according to the method for attaching the regulating unit 7, when the sliding door shoji 3 is moved toward the left vertical frame 43, the tip of the sliding door shoji 3 comes into contact with the regulating member 70, and the sliding door shoji 3 is further moved toward the left vertical frame 43. When the regulating member 70 moves to the side, the regulating member 70 moves to the left vertical frame 43 side together with the sliding door shoji 3, and also moves upward guided by the holding member multi-stage inclined portion 72h. When the lower surface 70f of the first portion 70a of the regulating member 70 moves above the sliding door shoji 3, the regulating member 70 stops moving and the sliding door shoji 3 continues to move.
