Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention brings at least two doors into an opening of a cabinet, etc., by abutting each other at their inner ends, thereby closing the doors in a planar manner. In an inset or outset plane closing sliding door, etc., where one door is moved from this state so that it overlaps the front side or back side of the other door, it becomes a stacked open door condition. , relates to a lateral movement device for rolling elements using rollers or the like that carry the door and roll to open and close the door.

《Prior art》 Instead of the conventional sliding door in which there is a step in the door thickness direction between the doors, the above-mentioned flat-close sliding door without a step is currently attracting attention, but the existing Due to the structure of the door, unless a gap is provided between the butt ends of the two doors, the doors cannot be opened or opened so that the doors are stacked on top of each other, so it is not possible to completely close the door. Furthermore, there are various problems in terms of use, manufacturing, and cost, such as the fact that the door cannot be opened or moved unless the back surfaces of the butting ends of both doors are chamfered into an inclined state.

Therefore, in an attempt to solve the above problem, the applicant has already provided two guide pins at both the upper and lower ends of the left and right doors, at both the inner and outer ends in the door width direction, and on the other hand, the door mounting frame An upper wall door rail formed on the upper wall and the lower wall by a straight part at the center, sloped parts at both left and right ends of the straight part, and longitudinal guide parts at both left and right ends of the straight part; The door rails for the lower wall are installed in parallel, and the guide pins at both the inner and outer ends of the door in the width direction engage with the guide parts and inclined parts of both door rails, so that both the left and right doors are attached at their respective inner ends. We are proposing a flat sliding sliding door device that is configured so that the two doors open together in a flat closed state, and one door is stacked on the front or rear side of the other door. .

According to the above-mentioned door device, when both doors are closed in a flat state, both door rails are covered by the doors so that they are not exposed to the outside. Although it is certainly effective in that it is possible to create a completely closed door without any gaps without notches, and the structure can be simplified and manufactured at a low cost, the above-mentioned door device is
In order to receive the weight of the door on the guide pin, even if the guide pin is formed of rollers or rollers, the opening and closing operations of the door will be increased, and therefore it is not suitable for particularly large and heavy doors.

Therefore, it has been proposed to provide rolling elements such as rollers that roll under the weight of the door, separately from the guide pins, at the upper end of the door, or at both the upper and lower ends, at both the inner and outer ends in the width direction of the door. ing.

The rolling element is convenient for carrying the door and moving to open and close it, and is supported by a support shaft provided in a direction perpendicular to the door width direction, and is provided so as to roll on the flat part of both door moldings in the door width direction. be.

However, when the above-mentioned rolling element is provided, when opening and closing the door, hold the handle provided at the inner end of the door and pull it diagonally forward, and then insert the guide pin on the inner end side of the door from the guide part to the straight part. When the door is pulled out, the guide pin on the outside edge side of the door is pulled out halfway up the slope, causing the door to become tilted. When the door is further moved laterally, the guide pin is guided to the slope. As the door moves laterally, it becomes parallel to the opening edge of the door mounting frame, and thereafter the opening operation is performed in a parallel state, but at this time, the rolling elements on the outside edge of the door touch the door rail. The door rail is slid on the flat part of the door rail while being rotated not in the direction of rotation on the flat part, but in the direction of the support shaft that is substantially perpendicular to the direction of rotation.
Furthermore, when the door is closed, it is rotated in the opposite direction to the above and slid on the flat surface. Therefore, when the door is opened and closed in its width direction, it is smooth and nimble. However, when opening/closing the door, frictional resistance is added between the rolling elements and the door rail, making the door opening/closing operation difficult.If the rolling elements are metal rollers, the rolling elements and the door rail will wear out, especially the rolling elements. The rollers may wear unevenly, making it difficult for the door to open and close smoothly, and if rubber rollers are used, the rolling elements may be easily damaged due to torsional force being applied to the rolling elements due to the above-mentioned rotation and sliding. , there are problems such as causing malfunctions.

《Problems to be solved by the invention》 This invention attempts to solve the above-mentioned problems, and includes two guide pins and two rolling pins at the upper end of both doors, on both the inner and outer ends in the width direction of the door. In flat sliding sliding doors equipped with a moving body, when the guide pin is engaged with and disengaged from the inclined part of the door rail when the door is opened and closed, the door rail is designed so that the door can be transferred from the rolling body to the guide pin and supported. In the flat rail part, the relief part of the rolling element is recessed in the movement range of the rolling element, so that the weight of the door is supported by the rolling element when the door is opened/closed. The door can be opened and closed smoothly and easily, and when the door is opened and closed, the weight of the door is supported by the guide pin to prevent sliding between the rolling elements and the door rail and twisting of the rolling elements.
The purpose is to allow the door to be opened and closed easily, prevent wear and damage to the rolling elements and door rail, and improve durability.

《Means for solving the problem》 That is, the present invention has two guide pins provided at the upper end of the left and right doors, respectively at the inner and outer ends in the door width direction, and two rolling elements such as rollers. and a guide pin provided at the lower end of the door, which is arranged in parallel on both the upper and lower walls of the door mounting frame so that the door can be moved in the lateral and front-back directions by engaging each of the guide pins and each rolling element, respectively. In a lateral movement device for a rolling element in a plane closing sliding door or the like comprising an upper wall door rail and a lower wall door rail, the upper wall door rail is capable of rolling by engaging each of the rolling elements. At both left and right ends of the rail section, when the door is opened and closed, when the guide pins are engaged and disengaged from the sloped parts connected to the left and right ends of the straight part in the center, the door is moved away from the rolling element. The above-mentioned problem has been solved by providing a recessed relief part in the movement range of the rolling element, where the rolling element does not come into contact, so that the rolling element can be carried by the guide pin.

《Embodiment》 The following is a detailed description of the plane closing sliding door showing the embodiment of the present invention based on the drawings.As shown in Figs.
By butting the inner ends 1a and 2a in the width direction, the door becomes a planar closed door state, and the upper wall 3a, lower wall 3b, and left and right side walls 3c, 3d of the door mounting frame 3 of the cabinet etc. They are formed in the same size, with vertical and horizontal dimensions that allow the door to be in an outset state with almost no gap between them, and at the upper and lower ends of each door in the width direction of the door. Extending rearward from the outer ends 1b, 2b and fixing the brackets 4, 4, 5, 5,
At the inner ends of the brackets 4, 4, two guide pins 7, 7, 8, 8 are installed near both the inner and outer ends of the arms 6, 6 fixed in the door width direction, and also on the brackets 5, 5. One guide pin 9, 9 is provided symmetrically protruding inward in the longitudinal direction of the doors 1, 2, and is provided at both the inner and outer ends of the arms 6, 6, at the end thereof in the door thickness direction ( Two rolling elements 12, 12, 13, 13 made of rollers or the like are rotatably supported in the door width direction by support shafts 10, 10, 11, 11 installed in the front-rear direction).

On the other hand, each guide pin 7 to 9 and each rolling element 1
2 to 13 are engaged, and both doors 1 and 2 are guided so as to be able to open and close in the door width direction.
On the outer surfaces of the upper wall 3a and the lower wall 3b of the door mounting frame 3, one upper wall door rail 14 and one lower wall door rail 15 are arranged symmetrically in parallel.

Both door rails 14 and 15 are connected to the door mounting body 3.
The upper wall door rail is provided near the opening 3e and parallel to the opening edge 3f, so that the rolling elements 12 to 13 carry the doors 1 and 2 and are guided to run in parallel. 14 is a straight plane rail part 14a, and a central straight part 14b which is provided so as to be guided in parallel with the doors 1 and 2 by engaging each of the guide pins 7 to 8, respectively;
Two inclined portions 14c, 14c are connected to each other at both left and right end portions of the straight portion 14b, and are bent rearward and outward.
Two longitudinal guide portions 1 are provided on both left and right sides of the center portion of the straight portion 14b, respectively, and are bent rearward and outward.

In addition, the lower wall door rail 15 has a central straight portion 15a and a straight portion 1 that engages the guide pins 9, 9 so that both doors 1, 2 are guided in parallel.
It is formed of two inclined portions 15b, 15b which are curved rearwardly outward and connected to each other at both left and right end portions of 5a.

The above inclined portions 14c, 14c, 15b, 15b
is provided so that when both the left and right doors 1 and 2 are opened and closed, they rotate and tilt around the guide pins 8, 8, 9, and 9 on the outside edges 1b and 2b of the doors as fulcrums to prevent mutual interference. On the other hand, the guide portion 14d,
14d, when the left and right doors 1 and 2 are opened and closed, the guide pins 7 and 7 on the inner side edges 1a and 2a of the doors are arranged so as to enable the above-mentioned rotation and sliding movement of the doors 1 and 2 with respect to each other. In the longitudinal direction of the doors 1 and 2, it is formed in communication with the straight portion 14b so as to be engaged and guided so as to be able to move diagonally toward the other door.

Moreover, the straight portion 14 of the above-mentioned both door rails 14, 15
b, 15a and inclined portions 14c, 14c, 15b,
15b and the guide portion 14d of the upper wall door rail 14 are provided in a groove shape, and the upper wall door rail 1
Reference numeral 4 denotes the straight portion 14b' that engages the guide pins 7 and 8 at the upper end of the right door 2, and the inclined portion 1.
4c and the guide portion 14d are wide and shallow, and a straight portion 14b'' that engages the guide pins 7 and 8 at the upper end of the left door 1 and an inclined portion 14.
c and the guide portion 14d are narrow and deep and communicate with each other at the center as shown in the figure.

In this way, when both doors 1 and 2 are opened and closed, the guide pins 7 to 8 of one door are prevented from being engaged with the guide portion 14d of the other door. 1 and 2 can be opened and closed in parallel.

Further, as the guide pins 7 to 9, it is preferable to use a ball caster or a roller having a small diameter portion at the tip and a large diameter portion at the base end, as shown in the drawing.

Further, as the rolling elements 12 to 13, it is preferable to use metal rollers, rollers made of hard rubber, or hard plastic, which are suitable for receiving the weight of the door and have sufficient strength.

Further, the guide pins 7 to 9 are provided only to guide the movement of the doors 1 and 2 when the doors are opened and closed, and as described later, they are used instead of the rolling elements 12 to 13 only when the doors are opened and closed. Since the weight of the door is to be received, the inclined portions 14c, 14
Inclined portion 15 of lower wall door rail 15 excluding c
b, 15b, the straight portions 14b, 15a of both door rails 14, 15, and the guide portions 14d, 14d are provided so as to be guided in contact with the side wall surfaces thereof without contacting their bottom surfaces.

Furthermore, when the left and right doors 1 and 2 are opened and closed,
The inclined portion 14 rotates and tilts around the guide pins 8 and 9 on the outer ends 1b and 2b in the door width direction as fulcrums.
c, 14c, 15b, 15b, and guide portion 14d,
Each guide pin 7 to 9 is connected to the straight portion 14 along 14d.
b, 15a, the rolling elements 13, 13 at the outer ends in the door width direction are pulled out forward to a position where mutual interference is prevented, or are operated in the opposite manner to the above. ,
Plane rail portion 14 in upper wall door rail 14
Rolling elements 1 are placed at both left and right ends of the flat rail portion 14a so as to separate from the upper surface of a so as to correspond to the movement range of the rolling elements 13, 13.
The relief portions 16, 16 of No. 3 are recessed into a groove with a concave cross section or a concave groove with a substantially arcuate cross section.

As a result, when the rolling elements 13, 13 move back and forth when opening and closing the door, the rolling elements 13, 13
The rolling elements 13, 13 are separated from the flat rail part 14a so that the rolling elements 13, 13 do not receive the weight of the door, so that the guide pins 8, 8 carry the doors 1, 2 instead, and the rolling elements 13, 13 are separated from the flat rail part 14a. After the portion 14a is pulled out to the front position, the rolling elements 13,
13 is in engagement contact with the flat rail portion 14a so that the rolling elements 13, 13 receive the weight of the door, but the guide pins 8, 8 do not receive the weight.

Further, ribs 17 are provided protrudingly along the opening edges of the inclined portions 14c, 14c, so that the large-diameter lower surfaces of the guide pins 8, 8 ride on the ribs 17 when the door is opened and closed. , 13 may be pushed up, and the relief portion 16 and the rib 17 may be provided together so that the guide pins 8, 8 receive the door weight instead of the rolling elements 13, 13.

Further, the front end of the relief portion 16 and the rib 17
It is convenient if the front end portions of the guide pins 16a and 17a are formed as inclined surfaces 16a and 17a, respectively, since the rolling elements 13 and the guide pins 8, 8 can be smoothly engaged and disengaged from the relief portions 16 and ribs 17.

In FIGS. 1 and 2, 1c and 2c indicate handles provided at the inner end of each door 1 and 2.

In the above configuration, the door opening/closing operation is performed in the first
The explanation will be made based on FIGS. 3 to 5.

As shown by solid lines in FIGS. 1 and 2, the left and right doors 1 and 2 are closed in a plane with their inner ends 1a and 2a brought together, and this closed state is not shown. The doors 1 and 2 are held by a stopper or the like, so that the two doors 1 and 2 are connected in a plane.
5b and the guide portions 14d, 14d, the rolling elements 13, 13 are located at the rear end portion of the clearance portion 16 provided at the end of the flat rail portion 16 of the door rail 14, and are in contact with the flat rail portion 16. The guide pin 8
8, and both doors 1 and 2 close the opening 3e with the opening edge 3f of the opening 3e in the door mounting frame 3 with almost no gap.

When opening the door 2 on the right side from the above-mentioned closed door state, first hold the handle 2c and follow the arrow a in Figure 1.
When the door 2 is pulled diagonally forward as indicated by , a forward force is applied to the guide pin 7 and the rolling element 12 at the inner end through the door 2, so the door 2 is centered around the guide pin 8 at the outer end. 4, the guide pin 7 is about to be rotated counterclockwise as shown in FIG. , the other guide pins 8 and 9 are guided by the inclined parts 14c and 15b and escape diagonally forward, and the guide pins 7 and
8 and 9 engage with the straight parts 14b and 15a, and the door 2 is mounted parallel to the opening edge 3f of the door mounting frame 3 and without interfering with the door 1 on the left side.
It is pulled out further forward to the position shown in FIG.

At this time, the guide pin 8 slides on the rib 17 under the weight of the door, while the rolling element moves forward while being separated from the flat rail part 14a by the relief part 16, and the guide pin 8 slides on the rib 17 due to the relief part 16. Immediately before the rolling element 13 escapes from the guide pin 14c, the rolling element 13 comes into contact with the flat rail part 14a, and receives the weight of the door instead of the guide pin 8.

When the door 2 is further moved laterally to the left as indicated by the arrow b in FIG.
Although it is only guided parallel to 4b and 15a,
The rolling elements 12 and 13 carry the door 2 and roll on the flat rail portion 14a, and the door 2 linearly moves parallel to the opening edge 3f to the open door end,
As shown by the two-dot broken line in FIG. 1, the door 1 on the left side is opened in a heavily mounted state on the front side, and is held in the open position by a stopper or the like (not shown).

Furthermore, when closing the door 2, when the door 2 is moved to the right from the open door position shown by the two-dot broken line in FIG. On the other hand, each guide pin 7 to 9 rolls in the straight part 1 of both door rails 14 and 15.
4b, 15a, the guide pins 8, 9 move to the left while remaining parallel to the inclined parts 14c, 15b.
However, when the door 2 is further moved to the right, the guide pins 8 and 9 engage with the inclined parts 14c and 15b, but at this time, in the illustrated example, the guide pin 8 rides on the rib 17, and on the other hand, The rolling element 13 has a relief part 16
Since it moves to the side and separates from the flat rail portion 14a, the weight of the outer end portion 2b of the door 2 is received from the rolling element 13 instead of the guide pin 8.

At this time, the guide pin 7 at the inner end is attached to the guide portion 14.
d, while the rolling element 12 engages with the door inner end 2a.
is supported and slid rearward on the flat rail portion 14a, and is closed as shown by the solid line in FIG. While the doors are closed in the butted state, the straight portions 14 of both door rails 14 and 15
b, 15a are prepared for opening the other door 1.

Also, when opening and closing the left door 1, the operation is the same as the opening and closing operation of the door 2 described above, so a description thereof will be omitted.

<<Effects of the invention>> Since the device for lateral movement of rolling elements in a plane closing sliding door, etc. according to the invention is configured as described above, when the door is opened/closed, the rolling elements 12, 1
3 rolls and runs on the flat rail part 14a of the door rail 14 under the weight of the door, while each guide pin 7 to 9 rolls and runs on the straight part 14 of both door rails 14, 15.
By being engaged with and guided by b, 15a, the door can be opened and closed smoothly parallel to the opening edge 3f of the door mounting frame 3, and when the door is opened and closed, the outer edge of the door When the guide pins 8, 9 are pulled out from the inclined parts 14c, 15b and pushed in, the rolling elements 1 at the outer edge of the door
3 is a relief part 16 of the rolling element provided at the end of the flat rail part 14a, so that it does not come into contact with the flat rail part 14a and is separated from the flat rail part 14a, and does not receive the door weight. Instead, the guide pin 8 absorbs the door weight. When opening/closing the door,
The rolling elements 13 are not only movable in the front and back direction (lateral direction) without interfering with or sliding on the door rail 14, so that the doors 1 and 2 can be opened and closed smoothly and easily. When opening/closing the door, by pulling out or pushing the inner side edges 1a, 2a of the door, the outer edges 1b, 2 of the door can be opened and closed.
b is guided by the inclined parts 14c and 15b and pulled out while rotating around the guide pins 8 and 9 as fulcrums,
In addition, by being pushed in, the rolling elements 13 are not forced to slide on the door rail 14 in a direction substantially perpendicular to the direction of rotation thereof, or are twisted, thereby reducing uneven wear of the rolling elements 13 and the door rail 14. This has remarkable practical effects, such as preventing damage to the rolling elements 13, thus improving durability, and allowing the use of low-noise rubber rollers, plastic rollers, etc., as the rolling elements 13 without any problem.
