Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a multi-folding screen in which the left and right vertical frames and the upper and lower horizontal frames are constructed from aluminum sections.

[Prior art]

As is well known, a multi-twin folding screen with two or more sets has adjacent folding screens bendably connected to each other by a hinge. By the way, when connecting folding screens, hinges that span almost the entire length of the wooden vertical stile or small hinges are often used, which not only makes installation extremely troublesome, but also makes it difficult to connect folding screens in banquet halls, etc. Folding screens used in Japan are used so frequently that they are easily damaged starting from the hinges, and repairing them requires removing the front and back sides, which is extremely troublesome. Recently, folding screens using frames made of aluminum profiles have also been proposed.
There are problems with attachment and connection to the core material, so it has not been widely put into practical use.

[Purpose of invention]

The present invention was made to solve the above-mentioned conventional problems, and aims to provide a multi-fold folding screen that is easy to attach and connect to the core material and is also sturdy.

[Summary of the idea]

The present invention provides a multi-double folding screen in which vertical and horizontal frames made of aluminum sections are attached to the outer periphery of a core material. A vertical stile with wedges erected on the surface, and a horizontal stile with notches on both ends and a wedge erected on one surface, each wedge is driven into a groove provided in the core material to form a folding screen. The present invention provides a multi-double folding screen in which mounting portions provided on the vertical frames of adjacent folding screens are connected by connecting pieces each having flexibility.

[Example of idea]

FIG. 1 is a perspective view showing a state in which an embodiment of the multi-folding screen according to the present invention is used. In the figure, 1a to 1
d is a single-twin folding screen, 2 is its core material, and a groove 3 having a width W ₁ and a depth H is formed on the circumferential surface of each core material 2. 4 and 4a are left and right stiles made of aluminum profiles, an example of which is shown in Figure 3.
Attachment portions 5 of the connecting piece 10 are provided at both ends, for example, consisting of bottomed holes opening at the corners, and
A wedge 6 is provided protruding from the surface of the mounting portion 5 opposite to the opening side. Note that the width W ₂ of the bottom of this wedge 6 is slightly larger than the width W ₁ of the groove 3 provided in the core material 2 . 7 and 7a are upper and lower horizontal frames made of aluminum profiles, an example of which is shown in Figure 4.
Notches 8, 8a are provided at both ends in the length direction, and between both notches 8, 8a,
A wedge 9 having the same shape as the wedge 6 of the vertical stile 4 is provided protrudingly.
Note that the width W ₃ of the notches 8 and 8a is the width W 3 of the groove 3 of the core material 2.
, and the length L of the notches 8, 8a.
is formed to be approximately equal to the depth H of the groove 3.

Next, an example of the assembly order of the folding screen made up of the above-mentioned parts will be explained. First, each double folding screen 1a to 1d
The wedges 6 of the vertical frames 4 and 4a are driven into the grooves 2 provided on both sides of the core material 2 and fixed. Next, the wedges 9 of the horizontal frames 7, 7a are driven into the grooves 2 provided above and below the core material 2 between the vertical frames 4, 4a, respectively, and fixed. At this time, both ends of the wedges 9 of the vertical frames 4, 4a are driven into the notches 8, 8a of the horizontal frames 7, 7a,
These are integrally and firmly fixed to form single-twin folding screens 1a to 1d.

Next, as shown in Figure 5, for example, a single double folding screen 1
Attach one end of a flexible connecting piece 10 made of, for example, a synthetic resin material to the mounting portions 5 (only the upper end is shown in the figure) provided at both ends of the vertical stile 4 of FIG.
Fix it with. Next, adjacent single-twin folding screens 1b are placed side by side with a slight gap between both vertical frames 4, 4a, and the other ends of the connecting pieces 10 are screwed into the mounting parts 5a provided at both ends of the vertical frames 4a. Fix it with 11a. In this way, adjacent single-twin folding screens 1a to 1d are successively connected to complete a multi-twin folding screen. Note that the above assembly order is an example, and it goes without saying that other orders may be used.

When using the single double folding screen constructed in this way, the connecting pieces 10 are stretched or folded and unfolded as shown in Figures 2a and 2b, and when stored, the connecting pieces 10 are unfolded as shown in Figure 2c. Fold and fold.

In the above description, a case is shown in which the wedges are erected over almost the entire length of the vertical stile and the horizontal stile, but two or more wedges of an appropriate length may be erected at appropriate intervals. Furthermore, although a case has been shown in which the connecting piece is fixed to the mounting portion with screws, other means may be used.

[Effect of idea]

As is clear from the above description, according to the present invention, it is possible to realize a double folding screen that is easy to attach and connect to the core material, has an elegant appearance, and is strong, so it is highly effective in practical use.
