BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to storage of a storage cabinet or the like.
In a cabinet with shelves, the front opening ,
A closing state and the suspended state lifting folding door, the lifting folding door by Noborido operation, it is possible to hold the door open state, by Fudo operate lifting folding door of the door opening state,
The present invention relates to a lifting door device capable of closing the opening.

[0002]

Conventionally, those that have been proposed as the lifting folding door apparatus of this kind cabinet, which comprises a structure as follows: As shown in Figure 5. That is, the upper part of the upper door c1 is hinged on the folding door mounting body a so that the upper end of the upper door c1 is rotatable in the vertical direction above the horizontal opening b.
1 and at the lower end of the upper door c1
An elevating folding door e is formed by connecting the upper end portion of the lower door c2 with a horizontal pivot support d2, and in the hanging state of the elevating folding door e, the horizontal opening b can be closed.

Here, according to the conventional example, the lower door c
Slide pins f are protrudingly provided on the right and left sides of the lower part of the slide rail 2 and are engaged with the slide rails g which are located near the lateral opening b of the folding door mounting body a and are vertically provided on the left and right side walls. The door opening operation as shown by the imaginary line of the elevating folding door e is guided so as to be movable up and down by being fitted.

If the elevating door e is raised by hand, the elevating door e is bent in a V-shape and moves upward, whereby the lateral opening b is gradually opened. Can go, but the open state must be maintained. For this reason, the balance weight i is connected to the pulley belt h connected to the slide pin f that moves up the slide rail g, and the pulley belt h is connected to the pulley j.
, The elevating / folding door e in the open state shown by the solid line is brought into an equilibrium state with the balance weight i so that the open state is maintained.

It is also known to automatically open and close the elevating / folding door e. For this purpose, a transmission mechanism that operates the slide pin f by a drive motor k opens and closes the door to a desired height. For example, various cylinder devices m are connected between the lower door c2 and the upper door c1, and the elevating door e is automatically opened and closed by the expansion and contraction operation of the cylinder device m. It is also known.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A key having a storage shelf according to the present invention
Per cabinets lifting folding door apparatus, cabinet having When Shoki following the embodiment of FIGS. 1-4, first with reference to the closing state shown in FIG. 2, the storage rack 11 such as by hanging cupboard
The upper part 2a of the upper door 2 is pivotally attached to the upper part 2a of the upper part 2 of the folding door mounting body 1 in the same manner as the previous one so that the upper part 2 is rotatable in the vertical direction at the upper part of the lateral opening 1a. Being pivoted. Here, a simple uniaxial hinge 3A or a slide hinge 3B or the like as shown in FIG. 2 may be appropriately used as the pivot attachment 3 , and in this case, the hinge body 3a is attached to the top of the folding door attachment 1. The cup 3 attached to the back surface of the plate 1b and linked with this by a pair of links 3b
c is attached to the upper inner surface of the upper door 2.

[0012] Here, in the illustrated example the upper door 2 Orito mount 1
In contrast to this, the external opening 1a is provided externally, but of course, an internal configuration in which it is fitted inside the horizontal opening 1a may be adopted.

[0013] In addition, this also as in the conventional example, upper door 2
The lower end 2b of the lower door 4 is connected to the upper end 4a of the lower door 4 in a hanging state by being pivoted by a lateral pivot attachment 5 such as a uniaxial hinge or the like.
The above-described lateral opening 1a is closed. Here, in the figure, 2c denotes an upper door handle provided on the lower outer surface 2d of the upper door 2, and 4b denotes a lower door handle provided on the lower outer surface 4c of the lower door 4, respectively.

In the illustrated example, since the elevating / lowering door 6 is externally attached as described above, the door is closed by holding the door in a hanging state.
It is desirable that the closed state of the elevating folding door 6 can be reliably held by an appropriate locking tool. In addition, in the case of the internal lifting / lowering folding door 6, a stopper or a magnet catch for preventing the insertion is appropriately provided in the folding door mounting body 1 so as not to be inadvertently pushed into the folding door mounting body 1. May be provided.

In the present invention, the conventional example without providing a slide rail and the slide pin as the mounting base 7 attached to the folding door mounting body 1, which a the sideways rotation shaft 8 projecting from the orthogonal shape , so that the vertical pivoting arm 9 is rotatable, rotation base 9a at the base end arm portion 9b
Is mounted on the shaft. Furthermore the free end of Kyoku突proximal end arm portions 9b so that with the base end arm portion 9b Karak-shaped 9
c is located on the lower inner side 4d of the lower door 4 and is linked by a folding pin opening / closing lateral pin 10.

[0016] That is, the mounting base 7, Orito mounting member 1 sideways opening inner surface of the side wall of the left and right that 1a to form 1
In the c, are fixed by screws 7a, Thus, the sideways rotation shaft 8 which projects so as to be rotatable in the inner surface of the side wall 1c and orthogonally shows the above-mentioned dogleg shape of the bent The rotation base 9a of the rotation arm 9 is pivotally mounted. Further, in the present invention, the free end portion 9c of the hanging portion 9d bent downward from the base end arm portion 9b of the rotating arm 9 is in the closed state of the elevating folding door 6, and the lower door is closed. against washer 4e was attached to the bottom inner surface 4d of 4, Orito opening and closing sideways pin 10 of the above-described horizontal direction rotational shaft 8 and the flat row state
Are linked by In addition, in the present invention, the storage shelf 11 laid between the side wall inner surfaces 1c of the folding door mounting body 1
The base end side arm portion 9b of the rotating arm 9 described above is disposed
The hanging part 9d bent from this is the storage shelf 11 and the side wall end face 1d at the lateral opening 1a of the folding door mounting body 1.
It is arranged between the two .

If the lower door handle 4b, the lower end of the lower door 4, or the upper door handle 2c in FIG. 2 is manually operated to raise and lower the folding door 6, the above-mentioned horizontal pivot can be obtained. When the support 5 rotates in the direction away from the folding door attachment 1, the lower door 4 and the upper door 2 are bent into a V-shape, and the lifting / lowering folding door 6 rotates upward. The horizontal opening 1a gradually increases its opening degree, and finally reaches the door opening state as shown in FIG.

[0018] That is, the rotating arm 9 by the above Noborido operation, rotates about a horizontal direction rotation axis 8, that Orito opening and closing sideways pin 10 is gradually moved upward as virtual circle line A in FIG. 1 in lifting Orito 6 is going to open door to Orito opening and closing sideways pin 10 and the sideways pivotal支具5 and pivot member 3 by deformation of the triangle having the pivot支頂point, the upper door 2 and the lower door 4 As the folding angle α having the horizontal pivotal support 5 as its apex gradually decreases, the door opening state gradually advances.

In this manner, when reaching the end of the opening / closing door 6 in the course of opening, the horizontal rotating shaft 8 of the mounting base 7, the horizontal pin 10 for opening and closing the folding door, and the horizontal pivoting support as clearly shown in FIG. The tool 5 and the virtual straight line B
The idea state is set so as to be arranged on the virtual straight line L. Therefore, if the door opening operation is further continued from such a conceived state and the elevating / folding door 6 is moved up, the elevating / folding door 6 which has been moved up to this point will maintain its open state by itself, and therefore the elevating / folding door 6 Even if the upward movement is stopped, the ascending / descending folding door 6 no longer descends, stops at the door opening position, and is held at this position by itself.

As described above, if the folding angle α in the thought state shown in FIG. 3 is α1, the folding angle α in the self-holding state shown in FIG. 4 becomes α2.
<Α1. Therefore, when attempting to operate the vertically movable folding door 6 from the self-holding state to the closed state, the lowering door handle 4b or the like is used to pull down the folding door 6 in the direction of the virtual arc line A. Of course, this allows the door to be closed, but as shown in FIG. 1, the lower door 4 is once pushed up from the self-holding state of the same opening as in FIG. From this state, the lower door 4 may be lowered in the direction of the virtual arc line A. Here, FIG. 1 is, of course, a longitudinal side view for facilitating understanding the relative relationship between the concept state of FIG. 3 and the opened self-holding state of FIG.

[0021]

Since the present invention is constructed as described above, the regulation mechanism of such opening and closing operation of the lifting folding door according to the slide rail and the slide pin has been considered indispensable In the traditional lifting Orito By deleting it, the overall configuration can be greatly simplified.

[0022] and, to the mounting base of the internally provided in Orito mounting body,
The pivotal arm is pivotally attached to the horizontal rotating shaft, and the free end of the pivotal arm is pivotally attached to the lower door with the folding door opening / closing lateral pin, so that the door can be smoothly opened and closed. Become like Furthermore, by forming a thought state shown as a virtual straight line in the middle of opening the door,
As long as the door is further opened, it is possible to hold the opened state without any effort and to release the hand of the door opening operation without any additional configuration, and the opening of the folding door can be opened. It can be kept as it is. As a result,
The proposal of the lifting / lowering folding door device which does not require the arrangement of the balance weight and the addition of the power mechanism as in the related art can be provided as an inexpensive, simple configuration and high durability.

Further, according to the present invention, the rotating arm is formed in a V shape.
Curved, with its pivot base on the horizontal pivot axis higher than the storage shelf.
In addition to pivoting, hanging parts are storage shelves and cabinets
Between the horizontal openings of the lower door, the free end of the lower door
Because it is pivoted inward, the shelf receiving surface of the storage shelf is sufficient
With a linear pivot arm.
Of course, the extension length from the horizontal opening is
It can be made smaller, so naturally the folding door will be in a high position when the door is opened.
