Description

[Detailed Description of the Invention] << Industrial Application Field >> The present invention is a top-hanging device for suspending a folding door or a sliding door, which is an external specification, in an opening portion of a cabinet or the like so that the folding door can be opened and closed by traveling. It is about rollers.

《Prior art》 Conventionally, there are two types of externally mounted (covered) folding door suspension rollers: a tip traveling roller for a fixed suspension source and a free traveling suspension roller without a fixed suspension source. The traveling roller is configured to travel therein.

FIG. 3 shows a state in which the folding doors b, b are attached to the cabinet a by the free running upper suspension rollers c, c'without a fixed suspension base.

As shown in FIGS. 4 and 5, the existing above-mentioned hanging rollers c and c'are provided with a pair of traveling rollers before and after the roller support d.
e, e and a roller part g on which a pair of guide rollers f, f are axially supported are connected to each other by a height adjusting screw h at a substantially central portion of the roller part g in a substantially inverted L shape on the front. The upper bracket portion i and the hinges k for attaching the folding door b to the upper bracket portion i are attached to the upper bracket portion i. At this time, the mounting positions of the hinges k, k have a positional relationship in which they are displaced laterally by a required dimension j from the position of the adjusting screw h.

<Problems to be solved by the invention> Therefore, when the above-mentioned conventional hanging rollers c, c ′ are used, when the folding door b is attached to the upper bracket portion i, the folding door b
Due to the eccentric load w due to the weight of, an inclination 1 is generated in the upper bracket portion i as shown in FIG.

Therefore, in this state, when the free-running folding doors b, b are folded and the folding doors b, b are made to travel in the left-right direction as shown in FIGS. The occurrence of this remarkable inclination l considerably hinders the running properties of the folding doors b, b.

That is, as shown in FIGS. 4 and 5, if the folding doors b and b are folded while the eccentric load w of the folding doors b and b is applied to the roller portion g and the upper bracket portion i, both front and rear sides can be folded. Top suspension rollers c, c ′
Is tilted to have a substantially C-shape on the front. In this state, when the folding doors b and b are pressed in the moving direction shown by the arrow m in FIG. 4, the front side is moved to the hanging roller c in a direction to correct the tilt l. Since the force is applied, the vehicle tries to travel in the upper rail n, but the rear upper suspension roller c ′ is applied with a force in a direction to further increase the inclination l. ,
As a result of braking the movement that e is trying to run, running performance is significantly reduced, running with large rattling and catching, or if the tilt angle becomes extremely large, the running rollers e and e will not run. If it is obstructed and it is attempted to move as it is, other members (eg hinges for attaching folding doors) may be damaged, or the upper rail n and the upper bracket i may come into sliding contact with each other.

The present invention has been made in view of the above problems of the above-mentioned conventional hanging roller, and it is possible to appropriately correct the inclination of the upper bracket portion due to the eccentric load of the folding door, and the roller portion and the upper bracket portion. The purpose is to dramatically improve the running performance due to the movement of the folding door by configuring so that and can always be held in parallel.

<Means for Solving the Problems> In order to achieve the above-mentioned object, the present invention has a roller portion in which a pair of running rollers are axially supported in the front and rear, and a substantially inverted L-shaped front shape, And an upper bracket portion, which is connected by a height adjusting screw at a substantially central portion thereof and is displaced by a required dimension from the height adjusting screw, and in which a hinge for mounting a folding door or the like is arranged, A parallel holding screw is screwed so as to be vertically slidable at a position away from the height adjusting screw of the upper bracket portion in the direction opposite to the mounting hinge side of the folding door or the like by a required dimension. At the same time, the present invention aims to provide an upper suspension roller in which the tips of the parallel holding screws are butted against the lower surface of the roller portion.

<Operation> The folding door is attached to the eccentric position of the upper bracket portion by the hinge.

By engaging the traveling roller of the roller portion with the upper rail, the folding door is movably suspended on the upper rail via the roller portion and the upper bracket portion.

When the folding door is suspended and the eccentric load due to the weight of the folding door is received and the upper bracket portion is tilted, the parallel holding screw is screwed according to the tilt, and the tip of the parallel holding screw is attached to the lower surface of the roller portion. Since they are butted against each other, the side of the upper bracket portion opposite to the hinge side for mounting such as a folding door is pushed up against the eccentric load, whereby the inclination is corrected, and the upper bracket portion becomes a roller portion. It will be kept parallel.

Therefore, when the folding door or the like is hung on the upper rail, the substantially C-shaped inclination that occurs in the roller portion and the upper bracket portion and the sliding contact state between the members are eliminated, and the folding door and the like are folded and moved for traveling. In this case, the resistance generated in the rear upper suspension roller is eliminated, and the folding door or the like can be smoothly moved.

<< Embodiment >> An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 and 2, the hanging roller A is composed of a roller portion 1 and an upper bracket portion 2.

The roller portion 1 is a roller support 3 that is formed long in the front-rear direction (left-right direction in the figure), and a pair of traveling rollers 4, 4 is arranged in the front-rear direction via a guide spacer 5 on a horizontal axis
In the illustrated example, a pair of guide rollers 7, 7 are rotatably rotatably supported by the rollers 6, 6, and a pair of guide rollers 7, 7 are provided longitudinally through the guide shafts 8, 8, respectively. Is rotatably supported by the upper rail 9, and the traveling rollers 4, 4 are engaged in the upper rail 9 having a substantially sectional shape, and the guide rollers 7, 7 are fitted in the opening 9a of the upper rail 9. Although it is configured to be able to travel in the front-rear direction in the fitted state, the guide rollers 7, 7 may of course be omitted.

On the other hand, the upper bracket portion 2 includes a horizontal plate portion 2a and a vertical plate portion 2b.
Is bent into a substantially inverted L shape on the front side, and the horizontal plate portion 2a
The guide shafts 8, 8 pass through both front and rear ends of the.

Each of the guide shafts 8 and 8 has a head portion 8a at the lower end,
By mounting the retaining ring 8b on the end portion which extends through the guide spacer 5 and extends upward, the roller portion 1 and the upper bracket portion 2 can be adjusted in height between them to have a required dimension. They are connected with the gap 0 held.

Further, the roller support 3 of the roller portion 1 and the horizontal plate portion 2a of the upper bracket portion 2 are connected by a height adjusting screw 10 at the substantially central portion thereof.

Further, a hinge base 11 is fixed to the vertical plate portion 2b of the upper bracket portion 2 by screws 12 ..., and two hinges 13 for mounting folding doors 13 and 13 are vertically screwed to the hinge base 11 (see FIG. It is fixed by (not shown).

That is, the hinges 13, 13 for attaching the folding door 14 to the upper bracket portion 2 are located at positions displaced from the position of the height adjusting screw 10 to the side (backward in the drawing) by the dimension p.

Here, in the present invention, in the horizontal plate portion 2a of the upper bracket portion 2, in the direction opposite to the folding door attaching hinges 13 and 13 side from the position of the height adjusting screw 10, a required dimension q is provided. A parallel holding screw 15 is screwed at a distant position so as to be vertically slidable, and its tip is provided with a roller support 3 of the roller unit 1.
So that the parallel holding screw 15 can be arbitrarily screwed and adjusted according to the inclination r generated when the folding door 14 is suspended from the upper bracket portion 2 by the hinges 13 and 13. Then, the inclination r of the upper bracket portion 2 can be corrected with respect to the roller portion 1.

In FIG. 1, B indicates a cabinet.

<Effect of the Invention> Since the present invention is configured as described below, the folding door or the like is hung on the upper bracket portion that is connected to the roller portion by the height adjusting screw at the substantially central portion thereof. At this time, the upper bracket portion is tilted, but the tilt can be corrected by adjusting the screw of the parallel holding screw so that it is always held in parallel with the roller portion. At the time of hanging, the substantially C-shaped inclination that occurs on both the front and rear upper hanging rollers and the sliding contact between the parts are eliminated, and as a result, the folding door is folded and it is attempted to travel and move. At this time, the resistance generated in the rear upper suspension roller can be reduced, and the running performance is greatly improved.

In addition, since the running performance is improved and the folding door can be smoothly moved, desired results can be obtained in terms of strength and stability without applying excessive force to other folding door components (such as hinges for attaching the folding door). To be
