Abstract

PURPOSE:To make the clearance between a door and an opening frame sufficiently small and enhance the working easiness by using a hinge consisting of an unequal four-gang link mechanism, and allowing the door to make opening/ tilting in the initial period of the opening operation while the door goes apart from the opening time. CONSTITUTION:A hinge 10 consists of No.1 short link 17 and No.1 long link 18 pivoted on the body 8 of a runner and No.2 long link 19 and No.2 short link 20 pivoted on a mounting plate 9. The tips of the short link 17 and long link 19 are coupled together by pivoting, while the tips of the other long link 18 and short link 20 coupled together pivotedly, and the one 18 is coupled with the one 19 by pivoting at their intersection P7. A door 3 is opened and closed round a floating fulcrum moving continuously and allowed to make opening/ titling while going apart from an opening door 26 in the initial period of the opening operation. Consolidating of the body 8 with the mounting plate 9 facilitates fitting and height adjustment.

Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention is a folding door applied to furniture, closets, etc., in which the door opens and closes on the outside of the front of the opening frame, and in the closed state, the door moves outside the opening frame. This invention relates to a runner that is applied to a so-called frame ring type folding door that covers the front surface.

[Conventional technology]

In a frame ring type folding door, the door approaches and faces the front end surface of the opening frame in the closed state. Further, the runner supporting the door is guided by a guide rail provided slightly inward from the front end surface of the opening frame.

For this reason, a special runner is used in frame ring type folding doors to avoid contact interference between the side edges of the door and the opening frame during the opening operation.

As a conventional runner of this type, a configuration in which a hidden hinge member is coupled to the runner body is known. (Utility Model Publication No. 6.3-46572). This hinge member is composed of two link plates, a cup that accommodates them, a connecting frame that connects the link plates and the runner body, and is used by embedding and fixing the cup in the inner surface of the door.

[Problem to be solved by the invention]

In the runner, the hinge member is constructed as a double link mechanism, and the fulcrum of the door opening operation is located on the inner surface of the door wall. Therefore, in the closed state, the door can be brought sufficiently close to the opening frame, and there is a disadvantage that a large clearance must be provided between the door and the opening frame to avoid interference.

Further, when attaching the hinge member to the door, a hole for embedding the cup must be formed on the inner surface of the door, which is disadvantageous in that this process requires time and effort.

Furthermore, when actually installing the door, it is necessary to adjust the installation height, but when burying the hinge member in the hole as described above,
The adjustment allowance was limited to the vertical allowance of the hole, making it virtually impossible to adjust.

The present invention has been made with attention to these points, and by constructing the hinge member with a four-link mechanism, it is possible to sufficiently reduce the clearance between the door and the opening frame. purpose.

Another object of the present invention is to obtain a runner that can be mounted on the inner surface of the door without making special holes, and that can also be freely adjusted in height and has excellent workability.

[Failure to solve the problem]

In this invention, the hinge 10 is configured with a four-link mechanism, and the door 3 is opened and closed around a continuously moving floating fulcrum.

Specifically, as shown in FIG. It consists of a long link 19 and a second short link 20. Then, the tip of the first short link 17 and the second long link 1
9, and the ends of the first long link 18 and the second short link 20, respectively, and further connect the first long link 18 and the second long link 19 at the intersection of both 18 and 19. The hinge 10 is configured such that the door 3 tilts while moving away from the opening frame 26 at the beginning of the opening operation.

[Effect]

Since the hinge 10 is configured as a four-link mechanism and the door 3 is opened and closed around a continuously moving floating fulcrum, R3 can be tilted open while moving away from the opening frame 26, especially at the beginning of the opening operation.

The hinge 10 is configured as a quadruple link mechanism, and this is integrated with the runner body 8 and the mounting plate 9 to make the whole into one unit part, so the mounting plate 9 can be directly fixed to the inner circumferential wall of the door 3. The fixing position in the vertical direction can also be freely adjusted.

〔Effect of the invention〕

As explained above, in the present invention, the hinge 10 is configured as a four-link mechanism, and the door 3 can be opened and tilted while moving away from the opening frame 26, so that the door 3 can be placed close to the opening frame 26 in the closed state. As a result, it is possible to sufficiently reduce the margin gap, which is essential for avoiding mutual interference between the two parts 3 and 26. As a result, in the frame ring type folding door, the folding door 2 can be closed to a state where it comes into almost close contact with the opening frame 26, and the appearance can be improved and the amount of protrusion of the folding door 2 can be reduced.

The hinge 10 is integrated with the runner main body 8 and the mounting plate 9, the entire runner is constructed as one unit part, and the hinge 10 is constructed using a four-link mechanism that can have a virtual hinge fulcrum in the outer space of the hinge body. Because of this structure, the mounting plate 9 can be directly mounted on the outer wall surface of the door 3 in an exposed state, and the fixing position in the vertical direction can also be freely adjusted by shifting the mounting position up and down. Therefore,
Not only can the runner be easily attached to the door 3, but also the vertical position of the folding door 2 relative to the opening frame 26 can be easily adjusted, improving workability during construction.

〔Example〕

FIG. 8 shows a storage cabinet equipped with a frame ring-type folding door, and the front opening of the cabinet body 1 is configured to be openable and closable by 2Mi folding doors 2, which can be folded into two.

The folding door 2 connects the left and right doors 3 with a hinge 4, and has -F section runners 5 at two locations above and below the inner surface of the free end of each door 3.
A and lower runner 5B are installed respectively. In FIG. 6, the upper runner 5A is guided and supported by a guide rail 6 attached to the bottom surface of the front edge of the top plate 1a of the cabinet body 1, and the lower runner 5B is guided and supported by the bottom plate 1a of the cabinet body 1.
They are guided by a guide rail 7 provided on the lower surface of the front edge of b, and can run left and right along the guide rails 6 and 7, respectively.

As shown in FIG. 1, the upper runner 5A includes a runner main body 8 that is suspended and supported by a guide rail 6, a mounting plate 9 that is screwed onto the inner surface of the door 3, and a quadruple chain that connects both 8 and 9. It consists of a link type hinge 10.

The runner body 8 is equipped with a pair of front and rear plastic rollers 13 via bearing brackets 12 on the upper surface of a U-shaped body bracket 11.

The mounting plate 9 has elongated holes 14 in series at the four corners of the plate surface, and a bracket 9a is formed at the lower end of the plate surface. An adjustment screw 16 attached to an adjustment fitting 15 that is separately screwed onto the inner surface of the door is screwed into this bracket 9a from below.

The hinge 10 has a wide first short link 17 pivotally connected to the back side of the main body bracket 11 so as to be pivotable about a fulcrum P, and a wide first short link 17 pivotally coupled to the front side thereof so as to be pivotable about a fulcrum P2. a pair of upper and lower first long links 18, and a second wide upper and lower long link 19 that is pivotally connected to a boss portion 9b protruding from the inner surface of the mounting plate 9 so as to be swingable about a fulcrum P3.
and a wide second short link 20 pivotally connected to be swingable about a fulcrum P4.

Among these, the tip of the first short link 17 and the second long link 19
The distal end of the first long link 18 and the distal end of the second short link 20 are pivotably connected about the fulcrum P6, and the distal ends of the first long link 18 and the second short link 20 are pivotably connected about the fulcrum P6.

Further, the first long link 18 and the second long link 19 are both 1
Pivotally connect at the fulcrum P7 at the intersection of 8 and 19. In other words, this hinge 10 is configured as a scalene link mechanism. Pin 2 provided in the middle part of the lower surface of the first long link 18
1 and a protruding piece 22 protruding from the lower surface of the main body bracket 11.

In FIG. 2, the lower runner 5B includes a runner main body 8 that is secured and guided by the guide rail 7, a mounting plate 9 that is screwed to the inner surface of the door 3, and a four-link type hinge that connects both 8 and 9. It consists of 10. The specifications of the hinge 10 are substantially the same as those of the upper runner 5A, except that the roller 13 of the runner body 8 is vertically rotatable, the mounting plate 9 is slightly smaller, and the spring 23 is not attached. Since the components are the same as those of the upper runner 5A, the same reference numerals are given to the components corresponding to those of the upper runner 5A, and the explanation thereof will be omitted.

When assembling the upper and lower runners 5A and 5B to the door 3, the lower runner 5B is first fixed in a fixed position on the door 3, and the upper runner 5A is fitted into the guide rail 6. Next, the lower runner 5B is fitted into the guide rail 7, the adjustment fitting 15 is fixed to the door 3 with screws, and at the same time, the mounting plate 9 is temporarily fixed with screws.

After this, the adjustment screw 16 is operated to adjust the vertical height position of the door 3, and the mounting plate 9 is permanently fixed. In this way, when the height of the door 3 is adjusted using the adjustment fitting 15 and the adjustment screw 16,
The height can be adjusted while the upper runner 5A remains attached to the door 3. In addition, in addition to the mounting plate 9 and the adjustment fitting 15, a seven-piece plate is screwed to the door 3 in advance, and after the adjustment fitting 15 is hooked onto the screws and installed, the adjustment fitting 15 is fixed with a hiss. Then, the upper runner 5
Attaching A to the door 3 becomes easier.

The folding moon phase runner according to the present invention is constructed as described above, and when the folding door 2 is extended and the front surface of the cabinet body 1 is closed, the hinge 10 is opened as shown in FIG. The mounting plate 9 is bent greatly and assumes a parallel attitude along the guide rail 6. In this case, cabinet body 1
A magnet 24 is embedded in the inner surface of the left and right side plate IC, and the runner main body 80 and the main body bracket 11 are attracted to the magnet 24. In this closed state, the spring 23 is connected to the hinge 1
0 and prevents the upper part of the door 3 from tilting outward due to its own weight.

From this state, for example, when you pull the right side folding door 2 toward you, the left side door 3 is bent forward and the right move towards At this time, since the hinge 10 is constituted by a scalene link mechanism, the mounting plate 9 moves forward in a substantially parallel posture at the initial stage of opening, as shown in FIG.
After that, it swings sharply forward. In other words, the door 3 moves around the continuously displacing floating fulcrum of the hinge 10 and tilts open while moving away from the opening frame 26.
It does not interfere with 6. Therefore, in the closed state,
The door 3 can be arranged sufficiently close to the opening frame 26, and the clearance gap between the door 3 and the opening frame 26 can be made sufficiently smaller compared to the conventional runner. In this example, the margin clearance was 4 mm or less.

In addition, the runner body 8 of the door 3 in the fishing source example has a magnet 24.
Since the door 3 is simply held by suction on the side plate IC, if the door 3 is pulled forcefully to the left, it will come off the magnet 24, and the door 3 on the right side can be folded and opened as the door on the hand side.

In addition, although the above-mentioned embodiment illustrated a bifold type folding door, it goes without saying that it can also be applied to a multi-stage folding door.
