Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screen used as a simple partition in a medical office such as a hospital, a doctor's office, a nursing care facility or an office.

[0002]

2. Description of the Related Art Conventionally, as a screen of this type, a rectangular frame is formed from a pipe made of aluminum or iron, legs are provided at the bottom of the frame to stand upright, and two frames are provided above and below the frame. The arm is laid horizontally and the curtain cloth is hung between them, or a plurality of them are connected.

Since these screens are lightweight and can be easily moved and installed, they are widely used as simple partitions in places where strictness is not required, but the size is usually 900 mm wide × height high. It is standardized as 1800 mm, so even if it is easy to move,
It lacks adaptability and flexibility for the installation site.

[0004] For example, when an elderly person uses a portable toilet while caring for an elderly person in a facility or at home,
A height of 800 mm is not required, rather a lower one is desired for viewing. Of course, for example, 1
If you prepare a 500 mm low one and use it, it will be appropriate in the above case, but if you move to another place and try to use it as a partition when not in use, the height will be low. This makes it unsuitable as a partition, and lacks the characteristics of such movement as a screen and ease of installation.

As a means for adjusting the width of such a screen, for example, in Japanese Patent No. 3240991, a beam is installed across the upper and lower parts of a pair of columns, and an inner pipe is attached to an outer pipe made of metal on both sides. A screen has been proposed in which a telescopic beam rod slidably inserted and a central portion is made of a flexible member using a rubber tube. In Japanese Utility Model Laid-Open No. 56-18768, casters are arranged. There is also proposed a screen in which an extendable upright column having locking pieces provided on the upper ends of the provided legs is fixedly mounted, and an elastic horizontal rod is provided on the locking pieces.

[0006]

However, these conventional screens include points to be improved in view of the characteristics required for the screens such as movement and convenience. That is, the screen using a flexible member called a rubber tube in the center portion of which the beam can be expanded and contracted can adjust the width by itself, which can be achieved by arranging a plurality of existing screens. The height cannot be adjusted, and the flexibility required for this type of screen cannot be satisfied. In addition, the screen in which both the columns and the beams can be expanded and contracted can be easily adjusted in height and width, but after the height and width are set to a desired size, the cloth is adjusted accordingly. However, it is complicated to adjust the above.

In view of the above situation, the present invention provides a screen excellent in simplicity and flexibility by making the columns of the screen expandable and contractible and adding a function of winding the curtain cloth on one beam. It is a thing.

[0008]

That is, according to the invention described in claim 1 of the present invention, the left and right columns forming the upper frame are extendably inserted into the left and right columns forming the lower frame. A screen characterized in that the main frame is formed and the upper frame is configured to be fixed to a predetermined portion, and a winding mechanism for expanding and contracting the curtain cloth in correspondence with expansion and contraction of the upper frame is mounted in the frame main body.

Preferred embodiments of the screen according to the present invention will be described below with reference to the accompanying drawings.
The present invention is not limited to the illustrated embodiments, but various modifications can be made without departing from the gist of the invention.

As shown in FIG. 1, the screen 1 of the present invention includes a lower frame 3 formed by bending one pipe made of a steel material such as aluminum or stainless steel or a synthetic resin into a substantially U shape, and the pipe. A frame main body 2 having a vertically long quadrangular shape as a whole, which is composed of an upper frame 4 in which a pipe insertable into the frame is bent in a substantially inverted U shape, and a curtain cloth 5 stretched in the frame main body 2. It is what is done.

In the frame main body 2, the left and right support columns 4a and 4b of the upper frame 4 are slidably inserted into the left and right support columns 3a and 3b of the lower frame 3 so that the entire frame main body 4 moves vertically. Left and right columns 3a, 3b of the lower frame 3 which are configured to be extendable and contractible
At the upper end of the upper frame 4 adjusted to the desired height
A fixture 6 having a hook 7 for fixing the hook 6 is provided, and engagement holes 8, 8 for engaging the hook 6 are provided on the inner surfaces of the left and right columns 4a, 4b of the upper frame 4 which face each other. ... are arranged with a required interval.

The hook 7 attached to the fixing tool 6 is always urged by a spring (not shown) so that the tip end thereof projects into the engaging hole 8, so that the connecting arm of the upper frame 4 is connected. When the upper frame 4c is pulled up and pulled up, it automatically disengages from the engaging hole 8 before moving and engages with the upper engaging hole 8. Therefore, if the upper frame 4 is stopped in that state, the upper frame 4 Is fixed to that position and is never lowered. When lowering the frame main body 2, the hook 7 is manually removed from the engaging hole 6.

The height adjustment of the frame main body 2 is not limited to the above-mentioned means. For example, a mechanism is provided in which a spring is provided in the column of the upper frame 4 and the force is used to fix the frame at an arbitrary position. Alternatively, a screw tightening mechanism or the like can be adopted.

An arm member 9 is arranged on the upper part of the upper frame 4 in parallel with the connecting arm 4c to fix the tip of the curtain cloth 5. Is provided with a protrusion (not shown) having a spring, the protrusion is inserted into the hole formed in the columns 4a and 4b, and is fixed by the spring so as to be freely detachable and fixed to the arm member 9. 5 can be removed for changing the pattern or washing.

The curtain cloth 5 is fixed to the arm member 9 by
In order to facilitate the removal of the curtain cloth 5, the tip portion is formed into a tubular portion by sewing or the like, and the arm member 9 is inserted into the formed tubular portion.

On the other hand, below the lower frame 3, a connecting arm 3 for integrally connecting the pair of left and right columns 3a and 3b.
An arm member 10 made of a pipe member that constitutes a winding mechanism for expanding and contracting the curtain cloth 5 corresponding to the vertical movement of the upper frame 4 is provided parallel to c.

The arm member 10 has a spring coil (not shown) built therein, and the terminal end of the curtain cloth 5 is fixed to the outer peripheral portion of the arm member 10 with an adhesive or an adhesive tape. Then, when the upper frame 4 is pulled down by the rotational force of the arm member 10 urged by the built-in spring coil and the tension acting on the curtain cloth 5 disappears, the curtain cloth 5 is wound around the arm member 10 and When the frame 4 is pulled up, the curtain cloth 5 is pulled out against the biasing force of the spring.

Further, the lower frame 3 has a pair of leg members 11, 11 on the connecting arm 3c in order to ensure self-supporting property.
Is fixed in an orthogonal state with a required space, and casters 12 with stoppers are provided at both ends of the back surfaces of the leg members 11, 11 to facilitate movement.

The curtain cloth 5 stretched between the arm members 9 and 10 is a cloth such as woven cloth or non-woven cloth such as tapestry, opaque film or sheet of synthetic rubber or synthetic resin, paper such as Japanese paper. Considering that it is widely used in hospitals and nursing facilities, it is preferable that these materials have antibacterial properties, deodorant properties, flame retardant properties, etc. A material in which a titanium oxide photocatalyst, zeolite, silica-alumina or the like is held is preferable.

In the above embodiment, the upper frame 4 and the lower frame 3 are each formed by bending one hollow pipe into a U-shape, but the point is that they are arranged with a required interval. If the left and right columns can be fixed in the vertical direction, for example, the arm members 9 and 10 may be used as substitutes for the connecting arms 3c and 4c, respectively. The same applies to the members.

The screen 1 having such a structure is moved to a desired position by using the casters 12, and in a place where a high screen is desired, the connecting arm 4c of the upper frame 4 and the like are grasped to move the screen 1 to the left and right. Pillar 4a,
4b is pulled out from the columns 3a and 3b of the lower frame 3, and the hook 7 is engaged with and fixed to the engaging hole 8 at the portion closest to the height to be fixed, and the height is adjusted.
The curtain cloth 5 is pulled out from the arm member 10 under tension at the same time when the upper frame 4 is pulled up, and is tensioned between the arm members 9 and 10 at the same time when the height adjustment is completed.

On the other hand, in a place where a low screen is desired, the hook 7 provided on the fixture 6 is engaged with the engaging hole 8 while maintaining the state in which the upper frame 4 is held.
, The columns 4a and 4b are inserted into the columns 3a and 3b, and the hook 7 is inserted into the engagement hole 8 at an arbitrary position,
The upper frame 4 and the lower frame 3 are fixed to each other, and at the same time, the curtain cloth 5 is wound around the arm member 10 so that the curtain cloth 5 has a desired length automatically without slack.

The screen 1 of the present invention is basically
It is preferable that the height can be adjusted to a minimum of 1200 mm and a maximum of 1800 mm from the viewpoint of versatility, convenience, and flexibility, and the width is 900 m, which is the same as the normal one.
It is preferably about m, but there is no particular limitation.

In the above embodiment, each of the upper frame 4 and the lower frame 3 is formed by bending one hollow pipe into a U-shape, but the essential point is to arrange them at a required interval. If the left and right columns can be fixed in the vertical direction, for example, the arm members 9 and 10 may be used as substitutes for the connecting arms 3c and 4c, respectively. The same applies to the members.

[0029]

The screen of the present invention is constructed such that the upper frame forming the frame main body is vertically expandable and contractable with respect to the lower frame and can be fixed at a predetermined position. Since the curtain cloth, which is always tensioned in correspondence with the height adjustment, is provided in the inside by the winding mechanism, the screen can be freely changed to the desired height, which is simple and flexible. It is highly effective and has an excellent effect that it can be widely used in examination rooms and offices such as hospitals, clinics, and nursing facilities.

Further, by using a curtain cloth used for this screen, which holds a deodorant, an unpleasant odor generated in a hospital, a doctor's office, a nursing facility, etc. and a cigarette odor generated in an office are removed. Will be even more suitable for use in places.
