Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to sliding doors for furniture and fittings;
To provide a flush sliding door which allows the front surfaces of both doors to be substantially on the same plane when both doors are closed, and which can be slid apart like sliding doors when the doors are opened.

[Prior art] Conventionally, this type of flush sliding door was developed in Japanese Patent Application Laid-Open No. 1986-
It is disclosed in Japanese Utility Model Publication No. 58237, Japanese Utility Model Publication No. 57-9975, Japanese Utility Model Publication No. 56-24786, and Japanese Utility Model Publication No. 1987-109715. In these systems, a direct horizontal slide guide groove and two pairs of guide slide guide grooves pulled out diagonally from this groove communicate with each other, and when the door is closed, both doors are positioned in the guide slide guide groove and are parallel to each other flush. When the doors are slid apart, one door is positioned in the horizontal slide guide groove and is slid behind the other door. is placed diagonally.

[Problem to be Solved by the Invention] According to the above configuration, since one door is located in the horizontal slide guide groove when sliding, the result is that one door is not opened more than the other door by the slope of the guide slide guide groove. becomes. In other words, the frontage was not sufficiently opened, making it inconvenient to use.

Furthermore, when opening and closing a sliding door that has a guide rail on the lintel and the sill, which starts from the mating side of the door when sliding, it is desirable to give directionality by leading from the lintel side. It has been found.

That is, for example, when changing a sliding door from a flush state to a sliding state, it must be slid diagonally by the guide slide guide groove and the guide pins and guide members of the upper and lower frames, but if it is not pushed strongly first, it will not slide diagonally. There will be no pressure on the person. In this case, if the degree of pressure is too strong, practical application will be avoided, so a structure that can be pressed lightly is required. However, if you make it lighter,
This creates a contradictory state in which it becomes impossible to maintain a flush posture. In this case, the fulcrum can be moved by shifting the guide slide guide groove, guide pin, and guide member on the matching side to the outside of the door, so it can be made lighter by pressing on the matching side. be.

For ergonomic purposes, it is preferable to give directionality to the upper side of the door, which is easier to press, so with the vertical direction of the door on the mating side as a reference, the guide slide on the lintel side should be placed against the guide slide guide groove on the sill side and the guide member on the lower door stile. If the upper fulcrum in the vertical direction of the door can be moved by slightly shifting the guide groove and the guide pin of the upper door stile toward the outer stile, it will be possible to move the upper fulcrum in the vertical direction of the door by simply pressing lightly on the upper part of the door assembly side to guide the direction. It is possible to wake up.

Moreover, if the guide slide guide groove on the sill side and the guide member on the lower door stile are set on the matching side to the extent that the flush posture can be maintained as described above, the posture can be maintained as before. This is because.

Therefore, the present invention has been provided based on the above-mentioned viewpoint, and its object is to facilitate the starting slide and to maintain a flush position.

[Means for Solving the Problems] A feature of the sliding door of the present invention for achieving the above object is that the guide slide guide groove on the lintel side and the guide pin on the door upper stile are connected to the guide slide guide groove on the sill side and the door. The extent to which the guide pin of the upper door stile can lead diagonally and give directionality by pressing the upper part of the door matching side against the guide member of the lower stile, based on the vertical direction of the door on the matching side. This is because they are placed slightly closer to the outer stile.

[Function] When the doors are closed, the guide pin and the guide member are located in the guide slide guide groove and are aligned flush, and the guide slide guide groove and the guide member on the mating side are aligned on the threshold side. Retained.

Next, when sliding the doors apart, the guiding slide guide groove on the joining side and the guide pin on the upper stile are located on the outer stile side, so that the door can be guided by simply pressing lightly on the upper part of the door joining side. This creates direction.

That is, when the upper part of the door assembly side is pushed from a free state, the guide pin moves obliquely to the guide slide guide groove, so that the upper part of the door assembly side is easily and slightly inclined. This inclination becomes so steep that the posture maintenance in the guide slide guide groove on the threshold side is released and the sliding movement is started.

[Embodiment of the Invention] The present invention will be described in detail below based on an illustrative embodiment.

The drawing shows the case where the present invention is implemented in a rocker 1, 2 and 3 are left and right sliding doors, 4 is a pair of guide members attached to the left and right sides of the lower stile of the slide doors 2 and 3, and 5 is each guide member 4.

Further, the guide groove 5 has a horizontal slide guide groove 10.
A pair of storage guide grooves 15, 15 are provided symmetrically from both ends to both sides. The storage guide grooves 15, 15 communicate with the horizontal slide guide groove 10, and horizontally guide the mating side of either door 2 or 3 from the horizontal slide guide groove 10 to the storage guide groove 15 on either side. , one door 2 or 3 is slid and stored behind the other door 3 or 2. Both doors 2 and 3 are the third
As shown in the figure, it is desirable to store the doors so that they match perfectly, but it is also possible to make the outer stile side of one door 2 protrude slightly from the mating side of the other door 3 to the extent that it does not affect the frontage. Of course it's a good thing.

The guide member 4 has a ball body 16 rotatably installed at its lower part, and provides directionality for horizontal or vertical sliding in synchronization with any groove shape of the guide groove 5. As shown in FIG. 5A, the ball body 16 is regulated by the side walls 5a, 5a of the guide groove 5 to determine its directionality, and is also oriented by the flat groove bottom wall 5b.
The structure is such that a point contact is made to obtain a smooth slide. Alternatively, as shown in Figure B, the bottom wall 5b of the groove is formed into a U-shaped groove to achieve line contact, so that a smooth slide can be obtained. The guide member has a main body formed in a cylindrical or prismatic shape, and a nut portion 18 is screwed into the main body through a threaded rod 17 provided on the main body so as to be freely accessible and detachable. Embed it up to part 19 and install it. If the doors 2 and 3 have attachment portions, the door attachment portion may be tightened between the main body and the nut portion 18 by inserting the threaded rod 17 into the attachment hole of the attachment portion.

The guide groove 8 of the lintel rail 9 has substantially the same shape as the guide groove 5 of the sill rail 6. That is, the guide groove 8
, horizontal slide guide groove 20, vertical slide guide groove 2
1, 21, and the predetermined shape of the retraction slide guide grooves 22, 22 are made to communicate with the matching guide grooves 23, 23 and the storage guide grooves 24, 24. Mating guide groove 2
3, 23 and the guide pins 7, 7 are respectively slightly deviated by α in the vertical direction of the door with respect to the positions of the mating guide grooves 13, 13 of the sill rail 6 and the guide members 4, 4, as shown in FIG. Place it on the stile side. The guide pin 7 has a spring 26 housed in the base 25 that presses the pin portion outward to make the pin portion expandable and retractable. The pin portions include a long pin portion 27 and a short pin portion 28.
Select multiple types. The long pin parts 27, 27 are attached to the upper stile of the doors 2, 3 on the mating side, respectively, and the short pin parts 28, 28 are attached to the upper stile of the outer stile side of the doors 2, 3, respectively. The guide pin 7 is located at the base 2
5 is mounted by embedding it in the upper stile of the doors 2 and 3 up to its flange 29. Further, the guide pin 7 has rollers 3 attached to the pins 27 and 28, as shown in FIG. 8D.
0 may be rotatably placed on the guide groove 8 to provide a roller guide within the guide groove 8.

Further, on the upper surface of the lintel rail 6, there is a first
movable plates 31, 31 and second movable plates 32, 32 are provided rotatably, respectively. More specifically, the first movable plates 31, 31 are attached via spacers 33, 33 to the rail corners formed by the lateral slide guide groove 20 and the matching guide grooves 23, 23, respectively. The second movable plates 32, 32 have storage guide grooves 24,
24 and the vertical slide guide grooves 21, 21, respectively. Each movable plate 31, 32 has a beak-shaped regulating piece 34, 34 formed therein. When the regulating piece 34 blocks the horizontal sliding direction, the beak-shaped abdomen forms a side wall along the vertical sliding direction, thereby forming a regulating position.

At the regulating position of each of the regulating pieces 34, the movable plates 31 and 32 are each provided with an operating piece 35 that projects in the vertical sliding direction. Each operating piece 35 is pressed by the vertical slide of each guide pin 7 to apply rotational force to the movable plates 31, 32, thereby switching each regulating piece 34 from the regulating position to the storage position. In the storage position, the regulating piece 34 blocks the vertical sliding direction, and its beak-shaped back forms a side wall along the horizontal sliding direction. Furthermore, the movable plates 31 and 32 have recesses 36.
and a regulating pin 37 installed between the recess 36, and both ensure switching between the regulating position and the storage position. 11 and 12 show another embodiment of the first movable plate 31, in which the first movable plate 31 is constantly pressed by a spring 38 as shown in FIG.
The action piece 35 is made to protrude into the matching guide groove 23, and applies a pushing force to the matching side of the doors 2 and 3 when the doors 2 and 3 are folded. In this case, the action piece 3
5 preferably protrudes at the mating position. Further, as shown in FIG. 13, a passage space 39 for the short pin portion 28 of the guide pin 7 is formed on the lower surface of the regulating piece 34 without interposing the spacer 33 on the lower surface of the first movable plate 31. It's okay.

Furthermore, as shown in FIG. 9A, the doors 2 and 3 may each have each guide member 4 and each guide pin 7 attached to the virtual center of gravity X located between the front and back in the thickness direction of the door. As shown in FIG. 9B, each guide pin 7 is attached to each guide member 4 at a position closer to the front side than the virtual center of gravity X, giving directionality toward the back side. In the latter case, vertical sliding or switching the sliding direction becomes easy.

Next, the operation based on the above configuration will be explained.

As shown in Figure 10A, each door 2, 3
are on substantially the same plane as a wall surface and are in the door closed position. In this case, each guide member 4 has a retraction ride guide groove 12, 12, a draw guide groove 13,
13 in the closed position, and each guide pin 7 is also located in the closed position of the retraction slide grooves 22, 22 and the mating guide grooves 23, 23.

In this case, the matching guide grooves 13, 1 on the threshold side
3 and the positions of the guide pins 7, 7, the posture is maintained in a flush state. Also, each movable plate 31, 3
2 is in the storage position as shown.

When opening either door 2,
As shown in Figure B, if a force is applied to the door 2 in the direction of the arrow (lateral sliding direction), the alignment guide groove 1
3 and 23, it is converted into a force in the vertical sliding direction.

That is, since the alignment guide grooves 23, 23 and the guide pins 7, 7 on the lintel side are located on the outer stile side by a slight amount α in the vertical direction with respect to the sill side, a force in the horizontal sliding direction is applied to the upper part of the door alignment side. For example, the guiding grooves 23, 23 are easily moved diagonally with the guide pins 7, 7 to lead. Along with this leading, the matching guide grooves 13, 13 on the threshold side
is led and starts moving.

Therefore, the outer stile side of the door 2 is guided by the retraction slide guide grooves 12, 22 and slides horizontally, and at the same time, the mating side is guided by the mating guide grooves 13, 23 and slides vertically to the lateral slide guide grooves 10, 20. . The first movable plate 31 rotates when the regulating piece 34 is pressed by the elongated pin 27 of the guide pin 7, and moves to the regulating position. The working piece 35 projects into the matching guide groove 23. When the movable plate 31 is biased by the spring 38 as in the embodiment, since the long pin 27 is pushed out by the action piece 35, not only is it easy to open the door, but also the movable plate 31 is biased by the spring force.
moves to the regulation position.

Next, when the door 2 is slid horizontally in the direction of the arrow on the side of the door 2 through the horizontal slide guide grooves 10 and 20, the outer stile side simultaneously slides through the horizontal slide guide grooves 12 and 20.
22 to the vertical slide guide grooves 11, 21, and then move to the horizontal slide guide grooves 10, 20 as shown in Figure C. In this case the second
The movable plate 32 rotates when the regulating piece 34 is pressed by the short pin 28 of the guide pin 7, and moves the regulating piece 34 to the regulating position. Further, the elongated pin 27 of the guide pin 7 on the door assembly side is guided by the back of the first movable plate 31 in the storage position to enable horizontal sliding.

Furthermore, if the door 2 is further slid horizontally in the direction of the arrow, the mating side of the door will be aligned with the horizontal slide guide groove 1.
0 and 20 into storage guide grooves 15 and 24, one door 2 is slid behind the other door 3 and is stored as shown in FIG.

In this case, the guide pin 7 on the matching side is well guided into the storage guide groove 24 at the back of the second movable plate 32, and at the same time, the short pin 28 on the outer stile side is guided by the first movable plate in the regulating position. 31 and is guided through the passage space 39 of the regulating piece 34.

Next, when closing the doors, pull one door 2 to the right in the figure as shown in Figure D, and the door 2 will easily slide sideways.
In this case, the short pin 28 on the outer stile side is not restricted by the restriction piece 34 of the first movable plate 31 in the restriction position, but passes through the passage space 39 of the restriction piece 34 and slides laterally.

As shown in Figure C, the short pin part 2 on the outer stile side
8 comes into contact with the regulating piece 34 of the second movable plate 32 and prepares to change direction in the vertical sliding direction.

As shown in Figure B, the outer stile side is retracted from the vertical slide guide grooves 11 and 21 to the slide guide groove 1.
2, 22, and at the same time, the matching guide groove 13,
Prepare for vertical slide to 23. In this case, the elongated pin portion 27 on the mating side comes into contact with the regulating piece 34 of the first movable member 31 in the regulating position and is regulated. Further, on the outer stile side, the short pin portion 28 presses the action piece 35 of the second movable plate 32 that projects laterally inward, so that the regulating piece 34 moves to the storage position.

As shown in Figure D, if the outer stile side of the door 2 is retracted along the retraction slide guide grooves 12 and 22,
The mating side is guided by the mating guide grooves 13, 23, and both doors 2, 3 are closed on the same plane. In this case, since the long pin portion 27 on the matching side presses the action piece 35 into the matching guide groove 23, the regulating piece 34 of the first movable plate 31 moves to the regulating position.

In this case, the matching guide grooves 13, 1 on the threshold side
The inner position of No. 3 maintains the flush posture.

Incidentally, when the other door 3 is opened or closed, the operation is similar to that described above.

[Effect of the invention] According to the double sliding door according to the present invention,
Move the guide slide guide groove on the lintel side and the guide pin on the upper stile to the guide slide guide groove on the sill side and the guide member on the lower stile, respectively, slightly toward the outer stile side with respect to the vertical direction of the door on the mating side. By arranging it, the lintel side could take the lead and give direction when sliding the sliding door, a smooth starting slide could be obtained, and a flush posture could be maintained reliably.
