Description

[Detailed Description of the Invention] The invention is based on combining at least two doors in an opening of a cabinet or the like with each other at their inner edges. By moving one door so that it overlaps with the front side of the other door, the opening is made to be in the open state. .

Conventional general sliding doors create a step between the doors, which spoils the aesthetics, so the above-mentioned flat-close sliding doors are starting to be used more frequently,
It is a PRAN outlet type installed inside the opening of the cabinet, etc., and because of this, the end face of the outer wall of the cabinet is visible, not only does it look bad, but if the outer wall becomes distorted, the door will not move properly. , It is troublesome and time-consuming to ask for a request.
Furthermore, due to the structure of the doors, unless a gap is provided between the butt ends of both doors, the doors cannot be opened or opened to form a stacked state, so it is not possible to completely close the doors. 11. If the butt end faces of both doors are chamfered in a beveled manner, they can be opened and opened.11. /1 etc. had various problems in terms of use, work, and cost.

Therefore, the present invention was developed in view of the above-mentioned conventional problems.
The upper and lower ends of both the left and right doors (in order to allow the running bodies such as rollers to be guided freely, several pieces of crushed earthen walls and lower wall guards are laid on each floor. The left and right ends of both rails are provided with an fRi inclined part bent backward, a rail switching part and a guide part, The door can be tilted forward and the rails can be switched, making it possible to completely cover the door.
The gap between the wall and the door can be made extremely small, and the gap between the doors can be completely closed, and it can be formed using a single rail. The purpose of this is to reduce the need for processing, etc., so that it is easy to order and can be provided at a low cost.

Hereinafter, the present invention will be described in detail based on the illustrated embodiments (as shown in FIGS. 1 and 2). Each door rail 2 for the earthen wall and the door rail 3 for the lower wall are provided.

Both rails 2.3 above are attached to the left and right doors 4.6.

The original number of the door is 2b, 2c, 3b, and 3c, respectively, so that the door can be tilted from front to back (this is bent toward the rear and can be tilted by at least the thickness of the door). In the case of the same figure, the door can be moved forward (and the door can be moved forward when it is near both ends of the straight section 2a of the door rail 2 for earthen walls). A rail switching section 6.7 is provided to enable the door to be opened, and in the case shown, a door rail 3 for the lower wall is configured to guide the door.
Near both ends of the straight portion 3a, guide portions 8.9 are provided, respectively, so as to allow the door 4.6 to move forward as described above.

As shown in Figures 1 to 5, both doors No. 4 and No. 6 are located at their outer ends and at approximately the center. Mounting bracket 10.1

5.16.17 are provided respectively, the running body 14.16 is for the upper wall, the running body 16.17 is for the lower wall, 3t engage each other.Thus, the opening part of the door removal 1 piece 1 (this is installed, but when installing this door, there is a gap between the door mounting frame opening edge 1C and the back side of the door 4.5). , set the clearance in advance so that there is no gap as much as possible, and then secure both rails 2 and 3 with the door mounting frame 11. Although the rail is shown in the installed state, it is of course a concave rail, and the rail may be configured so that the running body engages with the rail.

Furthermore, to explain the above rail switching part 6.7i,
As mentioned above, when the door is opened, it can be slid to the front so as to change the front side of the other door, and when the door is closed, it can be reversibly moved [this moves rearward, and both left and right doors 4.5 In order to ensure that the doors return to the flat state (this is the case) and the door can be closed, one of the doors 4 or 6
This is provided to guide the traveling body to open the door at position 1, where it completely covers the other door.

Its concrete structure is shown in FIGS. 8 and 9 (as shown in FIG. The guide plate 21 can be slid freely in the longitudinal direction and perpendicular direction of the rail portion 19, 20 by engaging with the guide plate 21. 2 in the longitudinal direction, and both rail parts 19 and 20 on the sliding base plate 18 are selectively fixed, and as part of the straight part 2a of the door rail 2 for earthen wall. It also has a configuration that allows it to be introduced freely.

In addition, the rail portion 20 on the board 18 (here, the stoppers 24, 24 for the traveling body 16 are provided upright, and when the door 4 or 6 is moved in the front-back direction, the above-mentioned This prevents the rail portion 20 and the traveling body 16 from coming uncoupled, and also allows the board 18 to be slid from this so that the rail portions 19 and 20 can be switched without any trouble. (It's getting better.

Further, the supplementary issue fitting 11 is formed in a side cursor shape, and the running body 15 is attached to the extending end 11a extending laterally from the tip thereof via a U-shaped cross-section fitting 11b. In this case, the other rail part 19 is rotatably supported, and the other rail part 19 is connected to the earth wall door rail 2 (when the door is closed as shown in FIG. , the running body 1 of the door 4 or 5 that is opened by the rail portion 191
6 is formed so that it can be guided by its weight.

On the other hand, the metal 413 fixed to the center of the lower end of the door 4.6
1) has the same configuration as the above-mentioned installation guide 11, and the stand shaft 26 which is erected from the extending end 13a of the running body 17 is rotatable as shown in FIG. I support it.

In addition, the door rail 2 for earthen walls has a substantially U-shaped cross section, while the lower wall door and rail 3 have a substantially U-shaped cross section. The traveling bodies 14 and 16, which are the rollers mentioned above, can roll (when engaged with each other, the guide parts 8 and 9 are arranged in a substantially '1' shape in plan view). E It is shaped like a bump.

The door mounting frame 11 is fixed so that the straight parts 8a and 9a of the lower wall door rail 3 constitute a part of the door rail 3 for the lower wall. The concave grooves 8b and 9b are formed to be able to receive the traveling body 17. Also, the mounting bracket 10 fixed to the outer upper end of both doors 4.6 is shown in FIGS. 6 and 7. As shown, it is formed into a substantially U-shaped cross section, and a roller (rolling body 14) is placed between the downwardly curved piece 10a at its tip and the piece 10b at an appropriate distance. is pivoted.

Furthermore, the mounting bracket 12 fixed to the outer lower end of the two doors 4.6 has a cross-sectional shape of
A nut shaft (not shown) is erected to rotatably support the roller (traveling body 16).

In addition, in FIGS. 6 and 7, 26 is a stopper for the upper wall, which is installed at both left and right ends of the rail 2.
The running body 14 comes into contact with the door to position the closed door.Then, the opening and closing operations of the door are shown in Figure 12 and Figure 13. )
(b) I will explain based on this.

As shown in FIG. 12 WIC, the left and right doors 4 and 6 are closed with their inner ends 4a and 5a abutting each other, and this closed door state is maintained by a stomper 26 provided at the end of the rail.
(The running bodies 14 are held in abutted state as shown in FIG. The other running body 15.15 engages with the inclined parts 2b, 2( of the door rail 2), and the other running body 15.15 engages with the respective rail part 20. of the switching part 6.7.
201 is engaged as shown in FIG. 13(a)1.

Moreover, for the door rail 3 for the lower wall at the lower part, the traveling body 16
．． 16 are engaged with the respective inclined parts 3b and 3c, while the traveling bodies 1γ and 17 are respectively secured to the guide parts 8.9, and both doors 4.6 are engaged with the opening edge 1G of the door 1. The opening is closed with almost no gaps.

To open the left door 4 from the above-mentioned closed door state, first hold the handle provided on the inner end 4al of the door 4 and pull it forward. Since a force is applied in the near direction to the substrate 18,
Rail parts 19 and 20 are moved toward the front side, CB+ and No. 13 in the same figure.
The rail part 20 moves as shown in the figure (I: IJ) and the rail part 20 coincides with the straight part 2a of the earth wall door rail 2 (C). Since it is rotated, the inner end 4a is rotated as shown in the same figure.
The side moves forward and becomes oblique. At this time, the lower roller 17 comes off the guide part 8 and moves to the straight part 8 a +.

Next, when the door 4 is moved to the right in FIG. do.

At this time, the running bodies 16 and 17 are already on the straight part 2a s 3 a of both rails 2.3, but the running bodies 14 on the other outer side
．． 16 is engaged with the inclined parts 2b and 3b of both rails 2.3, so it initially starts in an oblique state, but then moves to the right. The traveling body 14.16 rotates clockwise, and the traveling body 14.16 moves onto both rails 2.
3, the door 4 becomes parallel to the opening edge 1c of the mounting frame 1. From then on, the door 4 is opened in a horizontal position, and just before the opening door stop position, the traveling body 16 is moved to the right side door 6t. As a result, the rail portion 19 of the rail switching portion 7 that is slid is engaged as shown in FIG. 1C1 and FIG.
It is indicated by the two-dot broken line in cl. (The mounting bracket 11 collides with the mounting bracket 11 of the other door 6 and the door is opened, and the door 4 is heavily mounted on the outside of the other door 5.) i1(This is opened.

The open door positions shown in the figure differ slightly by 10 degrees for both doors 4.6, but this is due to the positional relationship between the mounting brackets 11.11, and this is slightly different from the outside of the door. Of course, if this is done, both doors 4 and 6 will be completely stacked and overlapped.

In addition, when closing the door 4, move the door 4 to the left from the open door state shown in FIG.
6.16.17 is the straight part 2a, 3a of both rails 2.3
+ Guided and moved horizontally 15 to the left, - When the traveling body 14.16 reaches the slopes 2b and 3bi, the door 4
The moving body 14 rotates clockwise and moves, and the traveling body 14 comes into contact with the Nutonopa 26 (the closed end is reached, but at this point, the door 4 is in the state [F] in the figure).

At this time, the other traveling body 15 is the rail part 2 of the LIJ exchange part 6.
o is engaged as shown in FIG.
, the board 1B moves rearward via the traveling body 15, and the traveling body 17 at the lower part also moves rearward, lowering the guide portion 8 (lower).
When the door 4 is closed as shown in FIG. 12, it is stored in the same plane as the other door 6.

In this way, when the door is first opened and when the door is closed, the inner end 4a of the door 4 moves forward and diagonally, so that when the door is opened and when the door is closed, it hits the other door 61. In particular, it is not necessary to provide chamfers or the like on both ends 4a and 53 of the door 4.6, and it is possible to close the door without creating a gap between the two doors 4.5.

Moreover, since the opening and closing of the other door 6 is the same as the opening and closing of the door 4 described above, the explanation thereof will be omitted.

Furthermore, Fig. 14 shows an embodiment in which the above-mentioned door rail 2 for earthen wall and door rail 3 for lower wall are arranged vertically upside down. It is also possible to arrange the members 1a' and 1b' so that the upper and 1a sides are in a guiding state and the lower wall 1b is in a suspended state.

As explained above, according to the sliding door rail for a covered door according to the present invention, both the left and right doors 4.6 have running bodies 14, such as rollers, provided at the upper and lower ends of each door.
16. One earth wall door rail 2 installed on the upper wall 1a and the lower wall 1b of the five-door mounting frame 1 so as to be engaged and guided so as to be openable and closable via 16.17, and one lower wall. The both door rails 2.3 are formed from straight parts 2a, 3a at the center, inclined parts 2b, 2c, 3b, 3c bent rearward at both left and right ends thereof, and a guard. At the same time, the switching part 6.7 of the door rail 2I is placed in the right place on both the left and right sides.
Guide parts 8 and 9 are installed respectively in the door, and when the door is first opened (there
Since the doors 4.6 are configured so that they can be opened by overlapping each other (the doors 4.6 are tilted forward relative to the other door), both the left and right doors 4.6 can be connected to one earth wall door rail. This allows the door rail 31 for the lower wall to be opened 19, and the door 4.5 can tilt forward in the closed door position without interfering with each other, so that the inner end 4a, There is no need to forcefully process the back side of 6a such as chamfering or leave a gap between both doors 4 and 5, so removal can be done easily and easily. It is possible to provide this at a low cost.

In addition, both left and right sides of the door rail 2 (switching parts 6 and 7 provided here)
is provided to guide the running body 16 of the other swinging door, so it is possible to completely cover and open the door, and in some cases, the closing door only has a small gap between the crushed opening edges 1c. Since there is no gap between the two doors 4 and 6, it is possible to completely close the doors.
