Description

[Detailed Description of the Invention] The present invention relates to lockers, cabinets, etc., particularly doors that are provided in parallel and open in the same direction.

Conventionally, various methods and shapes for attaching doors used in storage boxes such as lockers and cabinets have been proposed, and typical examples thereof are shown in FIGS. 1 and 2.

FIG. 1 is a cross-sectional view of a storage box with three parallel doors that open in the same direction, and FIG. 2 is a partially enlarged cross-sectional view of FIG. 1.

The storage box consists of a box frame and a door that is pivoted to the frame.
The frame body is formed of side plates 1, 1a, a bottom plate 2, a back plate 3, a partition plate 4, and a top plate 5 (see Figs. 5, 7, and 9), and has an opening 5 in one direction. ing.

The opening ends of the left and right side plates 1, 1a and the partition plate 4 are respectively bent to form vertical frames γ and 7a that receive the door 6. The stile 7a of the right-most side plate 1a) is bent symmetrically with the other stile 1.

The door 6 is integrally formed with a front plate 6a whose entire surface is smooth, a side plate 6b bent at a substantially right angle at both ends, and a ridge 6c further bent at the tip of the side plate 6b. , is pivotally attached to the frame via a hinge 8 at the side end (in this case, the right end in the figure when the door is fully closed).

Further, since the pivot point of the door 6 is located near the bending point between the front plate 6a and the side plate 6b, the door 6 can be fully opened to approximately 180 degrees as clearly shown in the figure.

A handle 9 is attached to the front side of the door opposite to the side on which the hinge 8 is attached, and a mirror 10 is attached to the back side of the door 6.

According to the above configuration, in order to store the door 6 between each of the stiles, that is, between the adjacent stiles 7, 7 or between the stiles 7.7a, the dimensions between the stiles and the door front plate 6
Accuracy of the width dimension of a is required, and there are also manufacturing difficulties such as the need to form complicated bends in the vertical stile 'I and ra parts of the frame, which reduces the manufacturing cost. It was causing it to pile up.

Therefore, in order to overcome the above manufacturing difficulties, a method has recently been proposed in which the door 6 as shown in FIG. 3 is attached in contact with the outer surface of the storage box frame.

According to this method, the pivot point of the door 6 is located on the back side of one side plate 6b and near the end, so when the door 6 is fully open, the side plate 6b on the pivot side is located on the back side of the stile 1. When the door 6 is fully closed, the protruding edge 6c of the other side plate 6b abuts the front surface 7b of the other stile.

Therefore, accuracy in the dimensions between the stiles and the width dimensions of the door straight plate 6a is no longer required, and in the example described above, since the door is stored between the stiles, each vertical stile has an abutment edge that abuts the door 6. γC was formed and the bending process was complicated, but in this case, since the door 6 abuts against the outer surface γb of the frame, the abutment edge 7c is not required, and the manufacturing difficulties are solved. .

However, in this case, the full opening angle of the door 6 is approximately at right angle because the side plate 6b of the door 6 hits the outer surface 7b of the adjacent frame, giving a psychologically cramped feeling in use, especially when the door is opened. When using the mirror 10 attached to the back side, it is difficult to use the mirror, so lockers using such a structure have not been widely popularized.

Further, each cabinet door is often large in size, and the door itself is easily distorted, so reinforcement is required to prevent distortion, which increases manufacturing costs.

The purpose of the present invention is to provide a storage box that is easy to process, does not require precision, and whose door can be opened widely.

Such an object is, as in the present invention specified by the claims, provided with a central portion whose one end is pivotally attached to the box frame body and protrudes toward the outside of the box; This is achieved by providing both inclined portions that are inclined toward the front surface of the frame, and further by forming the pivoting portion of the door to the box frame into an arc shape centered on the pivot shaft.

According to the present invention, it has a simple structure of just bending the door front plate to both sides, does not require reinforcement or high precision processing, and the opening angle exceeds a right angle, making it convenient for use. Moreover, it is possible to exhibit an unprecedented design effect in terms of appearance.

In addition, the pivot part of the door is formed in an arc shape centered on the pivot axis, and both sides of the door are sloped parts, so the door can be wide without being obstructed by adjacent doors. It can be rotated within a range and provides an easy-to-use storage box.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings from FIG. 4 to FIG. 10.

In FIG. 4, reference numeral 16 is an example of a door based on the present invention, and in a cross section, a central portion 16a protrudes outward over the entire vertical direction, and from both ends 15b, 16b of this central portion 16a. Sloped portions 16c and 16e are formed by bending in a direction that gradually reduces the thickness toward the side surface of the door 16 and across the entire top and bottom of the door 16.

The tip 16d of the inclined portion 16C on the - side is bent into an arc shape, and the center of this arc is the same as the center of the pivot shaft of the hinge 8, and the rotating piece 8a on one side of the hinge is fixed to the inclined portion 16c, and the rotating piece 8b on the other side is fixed to the partition plate 4 or the - side plate by spot welding or the like.

Furthermore, an L-shaped bent edge 16f is integrally formed at the tip of the other inclined portion 16e so as to form a groove opening toward the center of the inner side.

When the door is fully closed, the center portion 16a is configured to be parallel to the outer surface yb of the frame when the bent edge 16f abuts against the front surface 1b of the frame.

A handle 9 is attached to the inclined portion 16e on the side opposite to the attachment side of the hinge 8, and a mirror 10 is attached to the back side of the center portion.

A plurality of such doors 16 are successively disposed in the lateral direction at the opening of the box frame.

Because of this configuration, the door 16 is attached in contact with the outer surface of the storage box frame like the door shown in FIG.
In addition to simplifying the machining itself as it does not require machining precision,
The pivot portion to the box frame body is formed in an arc shape centered on the pivot axis, and both side portions connected to the center of the door are
Since the door is inclined in a direction in which the thickness is gradually reduced, the full opening angle of the door exceeds a right angle, and the door does not feel psychologically cramped during use, especially when using a mirror attached to the back side of the door.

Moreover, since the front plate of the door 16 is bent parallel to the pivot axis, the distortion that tends to occur when the door is fully closed is absorbed through the inclined parts 16c and 16e, and the appearance is minimal. It can be done inconspicuously.

Figures 5 and 6 show lockers equipped with doors according to the present invention.
As shown in the figure, the upper end of the door 16 has approximately the same height above the ground as the top plate 5 of the box, giving a sense of high overall length, which, together with the three-dimensional effect created by the bending of the door front plate, increases the product value.

Another embodiment of the invention is shown in FIGS. 7 and 8.

The difference from the above example is that there is a door 16 between the upper stile 11 and the lower stile 12.
is stored, and the door-side edge 5a of the top plate 5 is the first
As clearly shown in the figure, it is configured to substantially coincide with the door center portion 16a when the door is fully closed.

The advantage of this embodiment is that the intrusion of debris, rainwater, etc. can be prevented.

Externally, the upper accent creates a different aesthetic effect.

Still another embodiment of the present invention is the cabinet shown in Figs. 9 and 10. This cabinet is characterized by a two-door type without a partition plate, and the two doors are double-doored. There is.

From the above explanation, it can be understood that the storage box door has a simple structure of just bending, making it easy to process, allowing the door to open at a wide angle, and creating a novel design effect.
