Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door device for opening and closing an opening of a storage unit.

[0002]

2. Description of the Related Art For example, a sliding door as a means for opening and closing an opening of a storage unit or the like, whether of a sliding type or a single pulling type, generally has guide rails laid on upper and lower frames of the opening and extends along the rail. In this structure, the door is opened and closed by guiding rollers and guide pivots.

[0003]

For this reason, it is necessary to assemble the upper and lower frames and the guide rails on the opening side, but the work of attaching the upper frame and the upper guide rails is particularly troublesome. Further, in order to fix the guide rail, a reinforcing base material must be put in advance in the opening wall. Furthermore, it is necessary to attach a roller or a pivot to the door side.

An object of the present invention is to provide a sliding door device which does not require a guide rail or a reinforcing base material on the opening side and can be attached to an opening or the like without a guide rail.

[0005]

The present invention has the following configuration to achieve the above object. That is, the present invention relates to an improvement of a sliding door device that moves a door body in-plane in a horizontal direction with respect to a facing surface member. And
The present invention provides for either the door body or the facing surface member,
A guide means extending along the surface width direction is provided, and a sliding means guided by the guide means is provided on the other of the door body and the facing surface member. By making the facing surface member a second door body that moves in-plane in the horizontal direction in the same manner as the door body, a sliding door system is obtained. Further, by making the facing surface member a fixed surface member, a door device of a single-pull type or, in some cases, a pull-in type is obtained.

The guide means and the slide means are provided on the plate surface of one of the door body and the facing surface member.
A sliding means guided by the guide means is provided on a corresponding plate surface of the other member. When the facing surface member is a door,
Guide means are provided on the up-down direction end surface of one of the door bodies,
Sliding means guided by the guide means may be provided on the corresponding vertical end face of the other door body. When the guide means is, for example, a rail member, the sliding means may be a wheel member which slides and slides in the rail member.
When the guide means and the sliding means are provided on at least one of the upper and lower end surfaces instead of the plate surface of the door body or the like, the guide means may be formed as a groove, and the slide means may be formed as a sliding body which slides in the groove.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on illustrated embodiments. 1 and 2 are a side view showing a partial cross section of a sliding door device according to an embodiment of the present invention, and a cross sectional view of a main part thereof. The left and right doors 1 and 2 closing the opening 5 have the left door 1 (first door) on the front side in the depth direction as shown in the explanatory diagram of FIG. .
On the back of the first door 1, two upper and lower guide rails 3
Are fixed so as to extend in the surface width direction as seen in FIG. The rail groove of the guide rail 3 faces the front surface of the door 2 (second door) on the right side in the figure.

The second door 2 is provided with wheels 4 that are guided in the guide rails and rotate in a direction parallel to the plate surfaces of the doors 1 and 2. The wheel 4 is pivotally supported by a shaft 4a protruding from the inner end of the front surface of the second door body 2 that overlaps with the inner end of the first door body 1 when the door is closed. Not to be exposed. The first and second doors are
By engaging the upper and lower wheels of the second door body with the rails of the first door body, the two door bodies are integrated so as to be slidable in the width direction of the opening. Note that reference numeral 3a in the drawing denotes a rail 3.
This is a holding piece formed to fall down on the upper edge of the rail 3 in order to prevent the wheel 4 guided in the groove 3 from falling off (see FIG. 1).

Therefore, the first door 1 is smoothly opened and closed because the guide rail 3 moves along the wheels 4 when the handle 1a is pulled. On the other hand, the second door 2 performs a similar opening and closing operation because the wheels 4 roll inside the guide rail 3.

When the first door 1 is located on the rear side in the depth direction (see FIG. 4), the above-mentioned wheels are attached to the inner end of the front surface of the first door. A guide rail corresponding to this is fixed to the back surface of the second door body 2.

The present invention can be applied to a one-sided door as shown in FIGS. These doors move in-plane in a horizontal direction with respect to a fixed plate 6 which is a surface member facing the door body 1. In the example of FIG. 5, the above-mentioned wheels are mounted on the front surface of the side end of the fixing plate 6 near the opening, and in the example of FIG. 6, on the front surface of the side end of the door 1 near the fixing plate. on the other hand,
The guide rails are fixed to the back of the door 1 in the example of FIG. 5, and to the back of the fixing plate 6 in the example of FIG. The operation in these cases is the same as in the above-described examples of FIGS.

FIGS. 7 and 8 show an apparatus according to another embodiment of the present invention. This embodiment is applicable mainly to double sliding doors (FIGS. 3 and 4). In one door body 11 (the door body on the left side in the figure), the base end of the arm 15 is fixed to the upper end opening 11a. The arms 15 are provided in a pair at intervals in the length direction (the width direction of the plate surface) of the opening 11a.
The tip of the guide rail 1 extends in the depth direction of the door.
3 is supported. The guide rail 13 extends in parallel with the opening 11a of the door body 11 and reaches the upper end opening 12a of the other door body 12 (the door on the right side in the figure).

The other door body 12 has a groove formed at an upper end opening 12a. An inner rail 14 slidable in the guide rail is fixed to this groove. Inner rail 14
In the figure, a number of bearings 14a are attached along the length direction at positions where they contact the inner edge of the guide rail 13 (see FIG. 7). For this reason, the guide rail 13 and the inner rail 14
Are structures that can slide smoothly with respect to each other. The guide rail 13 is in a position where the inner ends of the inner rails 14 are retracted when the doors 11 and 12 are closed (the state of FIG. 7).

Therefore, in this embodiment, since the guide rail 13 as the guide means and the inner rail 14 as the slide means are attached to the door openings 11a and 12a of the doors 11 and 12, the front and rear faces of the door are provided. Do not see both means.
For this reason, the door body becomes clear. In the above-described drawings, the moving structure of the two doors has been described. However, it is needless to say that both doors are provided with appropriate self-supporting means.

In the case where the guide means is provided on the plate surface of the door body, the guide body of the guide means is provided with a gentle inclination in the width direction of the plate surface so that the door body is inclined with respect to the opposing surface member instead of moving horizontally. Can be moved. In this case, it is necessary to arrange the upper and lower ends of the first door into a required shape. In addition, the present invention can cope with a case where a pair of left and right doors are provided by applying the apparatus shown in FIGS. 1 and 2 or FIGS. 6 and 7 to the left and right doors. Further, the present invention can be directly applied to doors for opening and closing various openings other than the storage unit.

[0016]

According to the apparatus of the present invention, only the door body or the door body and the opposing surface member can be slid by the guide means and the sliding means provided on the plate surface of the door body and the opposing surface member or at the opening. Therefore, the door can be opened and closed without laying guide rails on the upper and lower surfaces of the opening. Therefore, it is possible to freely open and close the door at a position where there is no guide rail above and below.
