Description

[Detailed description of the invention] (1) Technical field of the invention The present invention relates to the structure of a runner for steadying the sliding door, which is opened and closed by hanging or running on the floor, including movement in at least the left and right directions. and a structure for front-back adjustment. The above-mentioned sliding door also includes a partition wall.

(2) Prior art and its problems Recently, in the sliding door structure of furniture and fittings, sliding door devices have been put into practical use in which the sliding door moves in the left-right and front-back directions when the door is opened and closed. The sliding door steadying structure in this sliding door device differs from the movement of conventional sliding doors in that the sliding door moves in the left-right and front-back directions, so it is a simplified structure used in conventional sliding doors. The steady rest runner cannot be repurposed. For this reason,
A steady rest structure described in Japanese Unexamined Patent Publication No. 57-119084 has been proposed. This steady rest structure includes a guide hole, which is an oblong hole drilled in the lower stile surface of the sliding door, and a guide mechanism in the center part of the sill (the part where the mating side of the sliding door is located when the door is fully closed). This guide mechanism consists of a guide and a spring. The guide includes an arm that is movably fitted into the guide hole,
The device includes an arm that receives the spring, and the branched portions of both arms are rotatably attached to a support shaft provided upright at the device fixing portion that constitutes the threshold. The proximal end of the spring is fixed to the sill. Therefore, this steady rest structure is a complicated structure that elastically deforms the spring while rotating the guide when the sliding door moves back and forth.

By the way, in the above-mentioned sliding door device, the sliding door is usually installed in such a manner that the gaps formed between the top and bottom plates and the side plates constituting the entrance and exit are uniform. When installing this sliding door, the mounting height of the runner on the running side is expanded or contracted to make the gap around the sliding door uniform, and the sliding door is adjusted from side to side. However, as a result of this lateral adjustment, the lateral position of the steady rest runner with respect to the guide becomes misaligned.
Furthermore, during the installation process, the sliding door is adjusted back and forth to ensure parallelism between the front surface of the entrance and the front surface of the sliding door. This longitudinal adjustment is normally performed by measuring the front and rear mounting positions of the guide, but even if this measurement is made accurately, the actual situation is that the longitudinal adjustment cannot be made properly due to assembly errors of the guide and the runner guided by this guide. be.

(3) Purpose of the invention The purpose of the present invention is to provide a runner for a sliding door rest with a simplified structure that facilitates the left-right adjustment and front-back adjustment of a sliding door in view of the conventional situation described above.

(4) Structure of the invention In order to achieve the above object, the structure of the present invention is used for a lower stile of a sliding door, which is constructed by suspending and guiding a pair of left and right sliding doors so that they slide in different directions when opened and are flush when closed. A steady rest member disposed toward either the vertical direction of the sliding door, and a mounting member that supports the steady rest member in a movable and adjustable manner by a piece divided toward the front and rear directions of the sliding door. The sliding door is characterized by having a horizontally elongated hole drilled in the mounting member and slidable in the left-right direction of the sliding door, and a round hole for final tightening.

As shown in FIGS. 1 and 2, the guide 3 has bases 40 of runners 4 and 5 and first and second guide pins 44 and 45 running in a suspended state, and an opening formed on the lower surface of the guide 3. The mounting bolts 41 of the runners 4 and 5 are passed through. The right center vertical guide 15 has an opening width slightly larger than the outer diameter of the first guide pin 45, and the depth of the right center vertical guide groove 15 is the same as that of the first guide pin 45.
It is deeper than the guide pin 44. Left center vertical guide 11
has an opening width slightly larger than the outer diameter of the second guide pin 45. The depth of the left central vertical guide groove 11 is deeper than the second guide pin 45 and shallower than the first guide pin 44. As shown in FIG. 6, the left central vertical guide groove 11 and the right central vertical guide groove 15 intersect in opposite directions within the horizontal guide groove 10. Therefore, the guide surface 11a of the second guide pin 45 is provided at the intersection of the left and right vertical guide grooves 11 and 15, respectively.
The guide surface 15a of the first guide pin 44 is formed in an arcuate shape with steps arranged in the vertical direction.

The guide 6 is connected to the device fixing part B as shown in the second figure.

On the other hand, as shown in FIGS. 2 and 4, the runner 7 is provided with a steady rest member 70 arranged toward the vertical direction of the sliding doors 1 and 2. This steady rest member 70
is attached to a mounting member 71, and by fixing this mounting member 71 to the lower stile of the sliding doors 1, 2, the steady rest member 70 is arranged in a spaced apart manner to the rear of the sliding doors 1, 2. When the sliding doors 1 and 2 are fully closed, the steady rest member 70 of the sliding door 1 is located at the end of the left vertical guide groove 62, and the steady rest member 70 of the sliding door 2 is located at the end of the right vertical guide groove 62. Ru.

Next, the structure of the runner 7 will be specifically explained with reference to FIG.

The steady rest member 70 has a cylindrical shape with an outer diameter slightly smaller than the opening width of the guide groove 61. This steady rest member 70 is a support shaft 7 erected at the tip of a support piece 710 of a mounting member 71, which will be described later.
It is rotatably attached at 11. The support shaft 711 is a shaft portion 711a that is rotatably fitted into a bearing hole 701 penetrated through the central axis of the steady rest member 70.
The length of this shaft portion 711a is equal to the length of the bearing hole 701.
slightly longer than the axial length of Shaft 711
A is provided with a disc-shaped head 711b at the upper end, and the outer diameter of the head 711b is larger than the diameter of the bearing hole 701 and smaller than the outer diameter of the steady rest member 70. Further, a shaft portion 71 is provided at the lower end of the shaft portion 711a.
A reduced diameter portion 711c having a smaller diameter than 1a is protruded. Then, while the shaft portion 711a is fitted into the bearing hole 701, the reduced diameter portion 711c is inserted into the through hole 712 bored at the tip of the support piece 711, and the protruding portion of the reduced diameter portion 711c that protrudes from the through hole 712 is inserted. By caulking around the through hole 712, the steady rest member 70 is rotatably attached to the support piece 710 at the shaft portion 711a while being prevented from coming off at the head 711b.

The mounting member 71 includes a mounting piece 713 that is fixed to the lower stile of the sliding doors 1 and 2, and a projecting piece 714 that extends horizontally to the rear of the sliding doors 1 and 2 is integrally attached to the lower end of this mounting piece 713. provided. This overhang piece 71
4 and the bending part 715 of the mounting piece 713 is the sliding door 1, 2.
It is located below the lower stile surface b. A plurality of horizontally elongated holes 716, 716 are bored in the upper part of the mounting piece 713 and arranged in parallel in the vertical direction. Each oblong hole 716
is elongated in the left and right direction of the sliding doors 1 and 2 (same as the lateral movement direction when opening and closing). Lower oblong hole 716
The mounting piece 713 located below has a thick hole 717,
A plurality of 717... are bored apart from each other.

The mounting piece 713 and the overhanging piece 714 are in the form of a band plate, and an escape groove 718 is carved in the center of the tip of the overhanging piece 714 in the left-right direction.
is a concave groove that opens upward and downward from the tip of the overhanging piece 714. This escape groove 718 and the bent portion 71
A female screw hole 7 is provided in the overhang piece 714 located between the

A mounting screw 720 is attached to each of the mounting screws 9 and 9, and the head 720a of each mounting screw 720 is attached to the projecting piece 714.
placed at the bottom of the

The support piece 710 of the mounting member 71 is plate-shaped, and upright walls 721, 721 are arranged in parallel on the left and right side edges of the support piece 710, respectively. The left and right distance L between the upright walls 721, 721 is the overhang piece 71.
It is slightly larger than the left and right width l of 4. The support piece 721, which is positioned at the lower part of the female screw hole 719 with the left and right side edges 714a of the overhang piece 714 along between the left and right walls 721, 721, has long grooves 722, 72.
2 is pierced. Each long groove 722 passes through the upper and lower sides of the support piece 721 and is open in a U-shape from the tip to the base end of the support piece 721.

In the embodiment configured as above,
The case of opening the closed sliding doors 1 and 2 will be explained with reference to FIG. 6. For example, in order to open the left sliding door 1 in FIG. 1A, the user operates a handle (not shown) provided in a recessed part of the sliding door 1 to pull the sliding door 1 forward. As a result, the second guide pin 45 located on the mating side of the sliding door 1
is guided by the left center vertical guide groove 11 and moves to the intersection of the left and right vertical guide grooves 11 and 15. At this intersection, the second guide pin 45
is guided to the right lateral guide groove 10 by the guiding action of the guiding surface 11a. Then, when the second guide pin 45 moves from the guide surface 11a to the horizontal guide groove 10 and exceeds the right center vertical guide groove 15, the outer diameter of the second guide pin 45 changes to the right center vertical guide groove 15. , the second guide pin 45 is prevented from entering the right central vertical guide groove 15 by the barrier effect of the stepped barrier 11c. Therefore, the runner 5 moves straight in the right lateral guide groove 10 toward the right end. Further, the runner 4 on the outer frame side of the sliding door 1 moves from the left adjustment guide groove 13 to the lateral guide groove 10 via the left end guide groove 12. As a result, the sliding door 1 is moved from the state shown in FIG. 6a to the state shown in FIG. 6b.

When the sliding door 1 is opened, the runner 7 provided on the lower stile of the sliding door 1 is guided from the right vertical guide groove 62 to the horizontal guide 61 as the sliding door 1 moves.
The mounting portion 70 of the runner 7 passes below the lower stile surface of the stationary sliding door 2. Then, the side end of the support portion 70 of the sliding door 1 comes into contact with the door stop 8 of the sliding door 2, and the opening operation of the sliding door 1 is completed.

Now, as shown in Figure 6b to Figure 6a, the sliding door 1
To close the door, simply open the door in the opposite direction to that described above. At this time, when the runner 4 of the sliding door 1 located at the front in the door closing direction passes through the intersection, the first guide pin 44
Since the first guide pin 44 is guided by the right center vertical guide groove 15 which is narrower and deeper than the first guide pin 44, the first guide pin 44 is prevented from entering the intersection of the left center vertical guide groove 11.
It is moved to the left lateral guide groove 10. Thereafter, it is guided from the horizontal guide groove 10 to the left adjustment guide groove 13 through the left end vertical guide groove 12 . Also,
The second guide pin 45 of the runner 5 on the mating side of the sliding door 1 is guided from the right horizontal guide groove 10 to the left central vertical guide groove 11 by the guiding surface 11a, and the sliding door 1 is flush with the sliding door 2, and the sliding door 1 The door closing operation is completed.

Next, the installation of the runner 7 and the installation of the sliding doors 1 and 2 will be explained.

With the supporting piece 710 removed from the projecting piece 714, the mounting piece 713 is positioned at a local fixed position of the sliding doors 1 and 2. This fixed position is near where the steady rest member 70 is located at the end of the vertical guide grooves 62, 63 when the sliding doors 1, 2 are fully closed. Then, a mounting screw (not shown) is screwed into the sliding doors 1, 2 while passing through the horizontally long holes 716, 716 from approximately the center in the left-right direction, and the mounting piece 713 is temporarily fixed. Thereafter, with the steady rest member 70 fitted into the guide groove 60, the support piece 710 is inserted into the lower part of the overhang piece 714 while using the upright wall 721 as a guide. and,
A part of the long grooves 722, 722 are female screw holes 719, 7
19, the tightening screws 720, 720
Tighten temporarily. In the above temporarily fixed state, the mounting pieces 713 and the overhanging pieces 71 for the sliding doors 1 and 2
It is sufficient that the mounting state of the support piece 710 on the mounting plate 4 is not rattled and that the left and right movement of the attachment piece 713 and the back and forth movement of the support piece 710 are allowed.

After the above temporary fixing, the sliding doors 1 and 2 are erected as follows. That is, after the sliding doors 1 and 2 are individually stopped at the fully closed door position, the mounting depth of the mounting bolts 41 to the sliding doors 1 and 2 is adjusted, and the upper stile surface a of the sliding doors 1 and 2 is adjusted.
The distance d1 between the base portions 40 of the runners 4 and 5 is adjusted in size. By adjusting the distance d1, the sliding doors 1 and 2 are adjusted to the left and right, respectively. That is, sliding door 1
When the distance d1 on the runner 4 side is increased, the outer stile side of the sliding door 1 moves down using the runner 5 as a fulcrum, and the entire sliding door 1 tilts to the right with respect to the entrance/exit. Furthermore, when the distance d1 on the runner 4 side is reduced, the outer stile side of the sliding door 1 rises using the runner 5 as a fulcrum, and the entire sliding door 1 tilts to the left with respect to the entrance/exit. Therefore, by adjusting the size of each interval d1 between the sliding doors 1 and 2, a uniform gap is formed between the entrance and the sliding doors 1 and 2.

During the horizontal adjustment described above, since the steady rest member 70 is located at the ends of the vertical guide grooves 61 and 62, the vertical guide groove 6
The barrier effect from the 1,62 terminals acts on the left and right,
Due to this barrier effect, the mounting member 71 moves from the temporarily fixed position in the left-right direction with respect to the sliding door 1 due to the guiding action of the mounting screws passing through the horizontally long holes 716, 716 and the horizontally long holes 716, 716 working together. In this moved state, mounting screws (not shown) are passed through the round holes 717, 717, and screwed into the sliding doors 1, 2, thereby fixing the mounting piece 713 to the sliding doors 1, 2 in a fully tightened state.

Also, while using the runners 4 and 5 as fulcrums, the sliding door 1,
Move the lower frame of 2 in the direction of the arrow X shown in the fourth figure,
The front and back adjustment is performed to maintain the gap d2 between the device fixing part B and the sliding doors 1 and 2 at a predetermined level. When this gap d2 is adjusted to a predetermined value, the tightening screws 720, 720 are screwed into the fully tightened state, and the supporting piece 710 is moved to the overhanging piece 7.
Fix it at 14.

According to this embodiment, the mounting member 71 is divided into a support piece 711 that fixes the steady rest member 70, and members that are fixed to the sliding doors 1 and 2 (an attachment piece 713 and an overhang piece 714). Therefore, the work of engaging the steady rest member 70 with the guide 6 can be easily performed. Further, when attaching the support piece 711 and the overhang piece 714, the upright wall 722 can be guided by the left and right side edges 714a of the overhang piece 714.

(6) Modification of the invention (a) The mounting piece 713A may be configured as shown in FIG. The attachment piece 713A is substantially parallel to the overhang piece 714. The mounting piece 713A has a horizontally long hole 716A.
is pierced. Therefore, according to this modification, the attachment piece 713A is attached to the lower stile surface of the sliding doors 1 and 2.

(b) As shown in the eighth figure, guide walls 721B, 721B may be provided on both side edges of the overhanging piece 714B. In this case, the standing wall 72 of the support piece 710B
1 is deleted.

(c) As shown in FIG. 9, guide walls 721C, 721C may be provided on both side edges of the overhanging piece 714C. This guide wall 721C is raised above the overhanging piece 714C. Therefore, according to this modification, the steady rest member 70 can be attached downward, and the guide 6 can be attached to the upper surface of the device fixing part B.

(d) As shown in Figure 10, the steady rest member 70D can be attached to the attachment member 71D so as to be movable back and forth. That is, steady rest member 70D
A bolt/nut mechanism F is interposed between the mounting member 71D and the bolt/nut mechanism F, and by operating the bolt/nut mechanism F, the steady rest member 70D is moved in the longitudinal direction. According to this modification, the sliding doors 1 and 2 can be adjusted back and forth while the mounting member 70D is integrated without being divided.

(e) As shown in Figure 11, attach the guide 6 to the device fixing part B.
It is also possible to attach it to the top surface of the In this case, the steady rest member 70e is attached toward the bottom of the sliding doors 1 and 2. This steady rest member 70e
The installation can be done as follows.

(i) Screw the tightening screw 720 into the female screw hole from above the overhang piece 714, and position the support piece 710 on the overhang piece 714 in the opposite direction.

(ii) Attach the steady rest member 70 with the support shaft hanging down on the lower surface of the support piece 710. Sliding door 1, 2

(7) Effects of the invention As explained above, the invention has the following effects.

(b) Since the mounting member that supports the steady rest member is provided with an oblong hole that becomes elongated in the left-right direction of the sliding door, by temporarily fixing the mounting member to the sliding door, even if the sliding door is adjusted from side to side, the guide will not move. No displacement of the steady rest member with respect to the terminal occurs.

(b) Since the steady rest member is supported by the mounting member so as to be movable back and forth, the steady rest member does not shift relative to the end of the guide during longitudinal adjustment.

(c) As a result of (a) and (b) above, there is no problem in opening and closing the sliding door after adjusting the left and right sides and front and back of the sliding door.

(d) By adjusting the back and forth movement of the steady rest member, the clearance between the steady rest member and the guide is reduced to prevent the front surface of the sliding door from becoming uneven when closed;
Can be assembled flush with each other.

(E) Since the mounting member is divided into a piece that supports the steady rest member and a piece that is fixed to the sliding door, it is easy to engage the steady rest member to the guide separately from fixing it to the sliding door. The steady rest runner installation work was simplified.
