Description

[Detailed description of the invention] [Field of industrial application] The present invention is a rail device that guides suspended sliding doors on furniture, such as sliding doors on the rear membrane of desks and sliding doors that cover the front of storage compartments of cabinets. It is related to the structure of

[Conventional technology and its problems]

For example, when covering the front of a storage compartment of a cabinet with a hanging type sliding door that can be opened and closed freely, rotating rollers are attached to the left and right sides of the upper part of the sliding door via mounting brackets at an appropriate distance, while the upper part of the front frame of the storage compartment is Usually, an upper rail is disposed on the upper rail, and the rotating rollers are supported on the upper rail so as to guide the sliding door so that it can be opened and closed from side to side.

When the front of the storage compartment is closed with a sliding door,
It is preferable that the front edge of the sliding door in the closing direction is in close contact with or close to the upper and lower longitudinal sides of the upper and lower longitudinal side supports or side plates of the front frame of the storage section in a parallel manner without any gaps.

On the other hand, even if the upper rail and the upper and lower longitudinal sides of the front frame are arranged at right angles, if the mounting height positions of the left and right rotating rollers at the top of the sliding door are different vertically, the front edge of the sliding door and the Unequally spaced gaps (triangular gaps) are created in the upper and lower parts between the upper and lower longitudinal sides of the front frame.

In other words, since the sliding door moves along the upper rail via the left and right rotating rollers, the front edge of the sliding door does not extend downward and at right angles from the upper rail. If the vertical distance to the upper edge of the suspended sliding door is short, the rotating rollers will have the same effect as if the upper edge of the sliding door was pulled up toward the upper rail, and therefore the lower position of the front edge of the sliding door will be closer to the upper and lower longitudinal sides. Since the front edge collides with the front frame first, a large gap is created between the upper and lower portions of the front edge and the upper and lower longitudinal sides of the front frame in the closed state.

In order to solve this inconvenience, conventionally,
A vertical and longitudinal groove was bored in the mounting bracket for the rotating roller attached to the upper part of the sliding door, and the supporting shaft of the rotating roller in the groove was configured to be adjustable in height with bolts and nuts.

However, even if the mounting height positions of the left and right rotating rollers at the top of the sliding door are the same, assuming that the upper and lower longitudinal sides of the front frame in the closing direction of the sliding door extend vertically, if the upper rail is not arranged horizontally, , Similarly to the above, the gaps between the front frame of the front edge of the sliding door and the upper and lower longitudinal sides are unequal in the upper and lower positions.

Moreover, if the upper rail is arranged so as to be inclined downward in the opening direction of the sliding door (this may be due to errors in the installation of the front frame of the storage section in the cabinet or the slope of the floor surface on which the cabinet is placed). ), as mentioned above, even if it is possible to eliminate the inequality in the gap when the sliding door is closed by adjusting the mounting height position of the left and right rotating rollers at the top of the sliding door,
The sliding door itself becomes easier to move in the opening direction. In order to eliminate this phenomenon and prevent the sliding door from opening accidentally, it is necessary to separately provide a latch device or the like between the sliding door and the front frame.

Such problems occur not only in cabinets, but also in sliding doors on the back panel of desks and sliding doors on other furniture.

The object of the present invention is to provide an upper rail device that can solve the above two problems with a simple structure.

[Means for solving problems]

In order to achieve the above object, in the present invention, a pair of left and right rotating rollers are attached to the upper end of a suspended sliding door of furniture at appropriate intervals along the opening/closing direction of the sliding door, and the upper rail is attached to the upper surface of the bottom plate of the above-mentioned rotating rollers. The bottom plate of the upper rail on which at least one of the rotating rollers rides in the closed position of the suspended sliding door has a longitudinal axis extending in the direction of movement of the rotating roller. A cut groove is provided, and a bottom plate portion on the side of the cut groove is formed as a stopping and mounting portion on which the rotating roller rides.

[Functions and effects of the idea]

According to this configuration, the stop and mount portion can be formed by simply bending the sides of the longitudinal cut groove provided in the bottom plate of the upper rail so as to protrude upward.

In addition, this stopping and mounting part absorbs all errors such as errors in the installation height of the pair of left and right rotating rollers, errors in the levelness of the upper rail, errors in the squareness of the rectangular shape of the hanging sliding door, etc. In this state, the front edge of the hanging sliding door can be brought into tight contact with the opposing side surfaces, making it extremely easy to prevent unequal gaps from occurring in the vertical and longitudinal directions.

〔Example〕

Next, we will explain an embodiment in which the present invention is applied to a hanging type sliding door installed in the rear membrane plate of a desk. In the figure, reference numeral 1 indicates a steel office desk for operating OA equipment 2, 1 is a pair of left and right legs 3,
A desk top plate 4 is provided between the front parts of the legs 3, and a pair of legs 3, 3
The rear end portion between the two is configured to be covered by a rear membrane plate 5 and a suspended sliding door 6.

On the rear side of the desk top plate 4, a slide top plate 7 of approximately half the left and right length of the desk top plate 4 is disposed so as to be movable left and right, and the remaining half portion is located at the rear end of the desk top plate 4. A vertically penetrating space 8 is formed between the hanging sliding door 6 or the rear membrane plate 5. Reference numeral 9 denotes an upper side that covers the slide top plate 7 and the space 8 above.

The rear membrane plate 5 is arranged below the desk top plate 4.
In order to send air to the OA equipment main body 11, a ventilation section 10 is formed by a large number of punched holes, and the downspout 12 for the upper and lower longitudinal cord passages to the OA equipment 2 on the desk top plate 4 is connected to the rear membrane plate 5. It is formed at an inner corner part connected to the rear end of the leg body 3.

Reference numeral 13 denotes a lower rail with an upwardly facing U-shaped cross section that guides the lower end of the hanging sliding door 6. Synthetic resin sliders 14, 14 protruding from both front and back sides near the lower end of the hanging sliding door 6 prevent rattling. You will be guided.

Reference numeral 15 denotes an upper rail that supports a pair of left and right rotating rollers 16, 16 that are attached to the upper end of the hanging sliding door 6 via attachment pieces 17, 17, respectively. , is formed into a horizontal U-shape in cross section, and has double rotating rollers 1 on the top surface of the bottom plate 18.
6 and 16 can be placed and rolled.

Reference numeral 19 denotes both rotating rollers 16 of the hanging sliding door 6.
The guide plate 19 has a notch (not shown) in the longitudinal direction midway through which the pair of rotating rollers 16, 16 can be inserted into the upper rail 15 side. ) is formed.

Reference numeral 20 designates a mounting bracket for connecting the end of the upper rail 15 and the leg 3.

Then, at 18 locations on the bottom plate of the upper rail 15 on which at least one of the pair of left and right rotating rollers 16, 16 rides when the suspended sliding door is in the closed position,
Two or one longitudinal cut groove is provided in the direction of movement of the rotating roller 16, and the stop/mounting part 23 is such that the rotating roller 16 runs over the bottom plate portion on the side of the cut groove.
It is to be formed.

In the embodiment shown in FIGS. 5 to 7, the pair of grooves 21 and 22 are formed when the front edge 6a of the hanging sliding door 6 that has moved along the upper rail 15 comes into contact with the side surface of one leg 3. When it is in the closed state, in the closed position, on both sides of the bottom plate 18 on which the lower end surface of the rotating roller 16 near the front edge 6a of the suspended sliding door 6 rests, in the direction of movement of the rotating roller 16. It is formed by notching an appropriate length dimension l1 along the
A stop mounting portion 23 for the rotating roller 16 is formed by appropriately bending the grooves 21 and 22 upward.

In the embodiment shown in FIGS. 5 to 7, the stop-mounting part 23 tilts the rotating roller 16 so that it can roll freely in the direction in which the hanging sliding door closes, and also stops and places the rotating roller 16 on the lower end surface of the rotating roller 16. The step dimension h1 between the part 23 and the bottom plate 18 at the abutting point is determined by correcting the discrepancy in the installation height of the pair of left and right rotating rollers 16, 16 in the suspended sliding door 6, and The gap between the edge 6a and the side surface of the leg 3 is set so that it is uniform vertically, and after the office desk 1 is assembled, the worker or user should not touch the handle of a screwdriver, a hammer, etc. The height can be adjusted to any desired height by knocking out the stop and place part 23 from the bottom surface.

With this configuration, for example, when the mounting height positions of the pair of left and right rotating rollers 16, 16 are different vertically and the hanging sliding door 6 is tilted as shown in the dashed line in FIG. Front edge 6 of hanging sliding door 6
The stop mounting portion 23 is made to protrude upward so as to lift the rotating roller 16 at the position a when the suspended sliding door is closed. As a result, the 8th
As shown by the solid line in the figure, the posture of the suspended sliding door 6 is corrected, and this stop placement part 23 has its rear side facing up so that it can easily move in the direction of closing the suspended sliding door 6 with the rotating rollers 16 on it. Since it has a high slope (see FIG. 9), the hanging sliding door 6 can be held in a closed state.

In this embodiment, if such a hanging sliding door 6 is provided on the rear membrane plate of the office desk, a large work space can be created behind the desk by opening the hanging sliding door 6. 2 and its main body 11, and since the hanging sliding door 6 is closed after the work is completed, the wiring cord is not exposed and the appearance does not deteriorate.

FIG. 10 shows another embodiment of the stop and place part 23, in which a recessed part 24 is formed in the middle of the longitudinal direction in the moving direction of the rotating roller 16, so that the suspension type sliding door 6 It is possible to maintain the stopped state in the closed position.

In FIG. 11, a pair of stop mounts 23, 23' are formed so that both left and right rotating rollers 16, 16 can ride substantially simultaneously when the suspended sliding door 6 is in the closed position. In this case, considering the difference in the mounting height positions of both rotating rollers 16, 16, in FIG.
The upward protrusion height of the stop and mount portion 23', which is raised by h3, may be appropriately set.

Furthermore, in the present invention, it is easy to understand from the above explanation that the stop and mount part may be formed to protrude upward only from the rotating roller 16 on the rear side in the closing movement direction of the suspended sliding door 6. Dew.

In addition, if the stop mounting part on which the rotating roller rests in the closed position of the suspended sliding door is formed in an inclined or concave shape so that the rotating roller can easily move in the closing direction, the suspended sliding door will be in the closed position. There is no need to provide a separate latch device since there is no need to inadvertently open the latch.

Furthermore, it goes without saying that the present invention can be similarly applied to a hanging type sliding door that covers the front surface of a storage section such as a cabinet.
