Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a screen that can be connected at a right angle or any other angle, which is extremely suitable for application to a screen for radiation protection, for example.

[Prior Art] Conventionally, for example, a curtain 6 is stretched between pillars 11 and 11' as shown by B in FIG.
A screen is known in which leg portions 12, 12' are fixed to the lower ends of each support column 11, 11' in an inverted T-shape when viewed from the end. This kind of screen has pillars located at both ends of the curtain, so when an accordion-style curtain is stretched, the screen itself can expand and contract freely, allowing it to be used stably to the required size, and also for storage. It is also convenient.

[Problems to be solved by the invention] However, with such conventional screens, when multiple screens are connected in series in a straight line, they can be lined up without gaps between each other;
If you try to use two screens by aligning their ends at right angles to form a corner, the legs 12 and 12' will protrude at right angles to both the front and back sides of the curtain 6 at the ends of the screen main body. , the legs get in the way of each other, and the corner part is 1/2 the length of the legs.
This creates a gap corresponding to the amount of radiation, which has the disadvantage that the protection purpose cannot be achieved, especially in the case of radiation protection screens. In addition, in order to prevent gaps from forming, it is necessary to butt the edge of one screen against the other screen in a T-shape, which causes one screen to protrude from the back of the corner, resulting in an undesirable shape for use. On the other hand, the entire surface of the screen will not be used.

The present invention solves these problems, and the ends of the screen are closely connected to each other and connected at right angles or other predetermined angles, forming corners with no gaps and connecting stably and reliably. It is made to be independent.

[Means for Solving the Problems] In other words, in the present invention, a curtain 5 is stretched between the pillars 1 and 1' located at both ends of the screen main body, and legs are attached to the lower ends of the pillars 1 and 1', respectively. In the screen where 2 and 2' are provided in an inverted T shape when viewed from the end surface of the main body,
A screen that can be connected at a right angle or any other angle, characterized in that a shaft 3 and a stopper 4 are provided at the lower end of at least one of the pillars 1, and the leg portion 2 is engaged with the shaft 3 so as to be rotatable and braking. be.

Since the present invention has the above-mentioned configuration, in normal use, that is, when used alone, the legs 12, 12' protrudes perpendicularly to the surface of the curtain 6, and the plan view of the main body is approximately square-shaped. When trying to form a right-angled corner, one leg 2 is rotated 90 degrees so that it matches the direction of the surface of the curtain 5, and when viewed in plan view as A in FIG. 3, it forms a T-shape. use. Normally, one rotatable leg is sufficient, but if both are used, a U-shaped connection structure with two corners can be created. It is also convenient to use a click-stop method for rotating the legs at two points: when they are perpendicular to the curtain surface, and when they are aligned with the direction of the curtain surface.

It is necessary to provide a stopper at least during normal single (non-coupled) use. Furthermore, when connecting the pillars and/or the legs of adjacent screens to each other by using any fixing means, such as a locking member or a so-called magnetic catch, the corner parts can be reliably connected. It is particularly preferred for use in radiation protection, since it is in a stable state.

[Example] Fig. 1 is a cross-sectional view of the rotating leg when not connected, and 1 is a column and 2 is a leg. A shaft 3 is formed at the lower end of the column 1, and is inserted through a hole in the center of the leg 2, and is screwed into a nut 7.
It is rotatably supported by. 4 is a stopper that reliably maintains fixation when discontinuous. FIG. 2 is a plan view showing that the stopper 4 is raised and the leg portion 2 is rotated so as to coincide with the tension line of the curtain 5 as shown by the chain line. This state is as shown by A in the plan view of FIG.

Next, as shown in FIG.
When the legs 2 of the screen A come into contact with each other, the pillars 1 and 11 also come into close contact with each other, as shown in the perspective view of FIG. It is formed.

In the above example, the curtains 5 and 6 are both accordion-type curtains made of lead-containing vinyl or rubber sheets.

[Effect of the invention] Multiple screens with pillars and legs at both ends,
In the past, when the screen surfaces were connected at right angles or at an arbitrary angle, the legs got in the way and a gap was created between the ends of the screen, but according to the present invention, the above structure is achieved. Therefore, the pillars and legs of adjacent screens can be closely integrated with each other and connected at the ends of the screen, making it easy to connect them at any angle, not just at right angles, without any gaps. The floor surface of the floor does not get in the way because the legs are not intertwined. Since the entire surface of both screens can be efficiently utilized to form any desired corner in a room, it is suitable not only as a general screen with pillars and legs at both ends, but also as a radiation protection screen in particular. The effect is extremely large.
