Description

[Detailed Description of the Invention] The present invention relates to a bed with side rails that has a simplified structure and is easier to handle.

As a bed for children or patients, to prevent children or patients from falling from the bed.
Alternatively, beds with side rails are required to prevent bedding from shifting or falling.

Various types of beds are conventionally known as this type of bed. (For example, Utility Model Publication No. 54-24811). Although FIG. 1 shows a bed according to the present invention and does not show the conventional bed described above, it has some parts in common with the conventional bed described above, so it is described in the above-mentioned publication with reference to FIG. 1 according to the present application. The conventional bed will be explained.

1 is the bed body. At the four corners of the bed body 1 are pillars 2, 2...2 for supporting the bed body 1.
is installed. Further, side rails 3 are installed on both sides of the bed body 1 so as to be able to rise and fall freely. Conventionally, in the bed with side rails, a stopper rod is provided at the bottom of the lower frame so that the stopper (same as instruction number 4 in Fig. 1) protrudes from near the tip of the lower frame of the side rail. A stopper receiving plate, which is installed separately from the lower frame and consists of a lower guide surface and an upper flat plate, is installed on one side of the support column 2, and the stopper rod is provided with a stopper portion that is elastically inward. A spring and an actuating lever are installed to cause the air to emit.

In such a conventional bed, when raising the side rail, the side rail is raised while pulling the operating lever toward you, and the stopper is slid on the guide surface and placed on the stopper receiving plate. At this time, the stopper is prevented from falling from the stopper receiving plate by the elastic force of the spring. When lowering the side fence, first pull the operating lever toward you, remove the stopper from the stopper receiving plate, and then lower it manually.

However, in the above-mentioned known bed, the stopper rod is attached separately from the side rail, and the structure is complicated because the operating lever and the spring are essential components. Furthermore, the above-mentioned known bed is difficult to handle because it is necessary to operate the operating lever when raising and lowering the side rail, especially when lowering it.

The object of the present invention is to provide a bed with side rails which is not only simple in structure but also easy to handle, and which overcomes the drawbacks of the prior art described above.

In order to achieve the above-mentioned objective, according to the present invention,
A bed main body, pillars supporting the bed main body installed upright at at least four corners of the bed main body, and a side fence having an upper frame and a lower frame installed on the side of the bed main body so as to be able to rise and fall freely. A stopper is protruded from the side of the side fence, a stopper receiving plate is fixed to the support, and the side fence is moved by raising and lowering the side fence and placing the stopper on the stopper receiving plate. A bed with side rails that can be set to any height, in which a rail with a "C"-shaped cross section is laid on one side of the support, and a roller is held at the end of the upper frame, and the roller is In the bed in which the end of the upper frame is freely attached to the support by fitting into the rail, one end of the arm is further attached to the end of the lower frame, and a roller is held at the other end via a pin. By fitting this roller into the rail, the end of the lower frame is freely attached to the support via the arm, a stopper is protruded from the end of the lower frame, and the stopper receiving plate is It is characterized in that a protrusion for preventing the stopper from falling protrudes from the tip.

Hereinafter, the present invention will be explained in detail using the accompanying drawings. Fig. 1 shows a specific perspective view of the bed with side rails according to the present invention, Fig. 2 shows a partially enlarged perspective view of part A in Fig. 1, and Fig. 3 shows a part of Fig. 1. An enlarged plan view is shown, and FIG. 4 is a partially enlarged side view of FIG. 1.

1 is the bed body. Supports 2, 2, .
A side fence 3 is installed on the side of the bed body 1 so as to be movable up and down. This side fence 3 includes, for example, an upper frame 5 and a lower frame 6.
During this period, multiple Tategi 15, 15,...
15 upright. Side fence 3
A stopper 4 protrudes from the side of, for example, the lower frame 6, and an arbitrary plurality of stopper receiving plates 7 are fixed to the column 2.

In this bed with side rails, the present invention has side rails 3
The frame 5 is characterized in that the end of the frame 5 is attached to the support 2 so as to be freely movable. For this installation, as shown in FIG. This is done by fitting the upper frame 5 into place, whereby the end portions of the upper frame 5 are attached so as to be movable up and down and also rotatable left and right.

Furthermore, the present invention is characterized in that the lower frame 6 is freely attached to the support column 2 via the arm 8.
As is clear from the drawings, especially FIG. 2 (enlarged view of part A in FIG. 1), this installation is done by attaching one end of the arm 8 to the end of the lower frame 6, and attaching the roller 11 to the other end via the pin 16. This is done by holding the rollers 11 and fitting the rollers 11 into the rails 9, whereby the ends of the lower frame 6 are mounted so as to be movable up and down and rotatable left and right.

Furthermore, the present invention is characterized in that the stopper 4 is fixedly attached to the lower frame 6 and is integrally attached to the lower frame 6, and a protrusion 14 for preventing the stopper 4 from falling is provided protruding from the tip of the stopper receiving plate 7. do. In the figure, reference numeral 12 denotes a stopper guide, in which a stopper receiving plate 7 is built. Also, 13
is a spring and has the function of springing the stopper 4 in the direction of the support column 2, but this may be attached as necessary and is not an essential requirement of the present invention.

In the bed of the present invention constructed in this manner, when pulling up the side fence 3, it is sufficient to simply hold any part of the side fence 3 and place the stopper 4 on the stopper receiving plate 7; 3, also remove the stopper 4 from the protrusion 14 of the stopper receiving plate 7 by holding any part of the side fence 3, and then move the stopper 4 to the stopper guide 12.
All you have to do is slide down the inner wall. At this time, the arm 8 rotates as shown in the imaginary line in FIG. 4, and at the same time, the side fence 3 can rotate using the roller 10 at the end of the upper frame 5 as a fulcrum (see FIG. 4), so the stopper 4 can be rotated as shown in FIG. It can be easily slid onto the inner wall of the par guide 12. Incidentally, if the side fence 3 is springed in the direction of the support column 2 by the spring 13, the above-mentioned lifting and lowering operations will be made easier.

According to the above-mentioned invention, when raising and lowering the side fence, there is no need to pull a lever as in the conventional method, and the operation can be carried out by holding any part of the side fence, making the operation easy. Further, since the stopper 4 is prevented from falling by the protruding piece 14, there is no need for a spring to be used as in the conventional case.

Further, according to the present invention, since the stopper 4 is integrally fixed to the lower frame 6, there is no need to provide a separate stopper rod as in the conventional case, and the structure is therefore simple.
