Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a floor status display mechanism for beds, patient carriers, examination tables, etc. whose floors can be raised, lowered, and tilted.

(Prior art and its problems) As a conventional mechanism for displaying the state of the floor in a bed or the like, for example, as shown in FIG. There is a mechanism in which a pointer b that can freely hang in any direction and a scale plate c are provided, and the inclination angle of the floor support frame a is displayed by the scale of the scale plate c pointed by the pointer b.

However, although this display mechanism can display the angle of inclination, it cannot display the amount of elevation in the vertical direction, that is, the height. In addition, since the installation position of this mechanism is limited to the side, it is not always easy to see the pointer b and scale plate c because they are obstructed by pinerests, sheets, etc. If this is done manually using the handle d or the like, there is a problem in that it is very cumbersome to operate while checking the status.

The present invention aims to solve the above-mentioned conventional problems.

(Means for Solving the Problems) The present invention will be explained based on FIGS. 1 to 5 corresponding to embodiments. The present invention has a structure in which a pair of display members 1a and 1b can be moved in parallel. One side of the outer members 3a, 3b is connected to the supported vessel body 2, and the inner wires 4a, 4b are connected to the vessel body 2.
A pair of wire devices 5a and 5b are provided, each of which connects one side to the display members 1a and 1b and moves the display members 1a and 1b in one direction.
In addition to providing reference indicators 6a and 6b on a and 1b,
An angle corresponding scale 7 is provided on at least one side, a vertical scale 8 is provided on the container body 2, and a spring means 9a for returning each of the display members 1a, 1b to the other direction on the container body 2; 9b and
The pair of wire devices 5a and 5b are connected to the bed 10.
The inner wires are placed at two appropriate positions h, h'; The other sides of the outer members 4a and 4b and the other sides of the outer members 3a and 3b are fixed. In the case of a bed that slopes in the longitudinal direction, the respective sides are both sides in the longitudinal direction, that is, the head side H and the foot side F,
In the case of a bed that slopes in the lateral direction, it is on both sides in the lateral direction.

Here, to explain the constituent elements together with examples, first, the display members 1a and 1b are shown in FIG.
As shown in FIGS. 2 and 3 a, it is configured as a band-shaped plate that does not deform during movement, and as shown in FIG. 3 b, it is configured as a band-shaped body that can be wound up and unwound during said movement. etc., as appropriate.
In addition, the pair of display members 1a and 1b are arranged horizontally adjacent to each other in parallel, as shown in FIGS. 1, 2, and 3b. They may be configured in parallel so as to be adjacent in the direction. Of course, in the latter case, the display member 1a on the front side is configured to be transparent. Next, the spring means 9a, 9b
As shown in FIG.
As shown in FIG. 2, the wrapped band-like body is configured as a mainspring or a constant torque spring, and the display member 1a,
1b itself may function as the spring means 9a, 9b. Furthermore, the reference display 6a, 6b,
The angle corresponding scale 7 and the elevation corresponding scale 8 may be constructed of lines, figures, symbols, characters, etc. as appropriate.
Incidentally, reference numeral 12 is a window for making the display members 1a and 1b visible from the outside, and this window 1
2 may be appropriately configured with a transparent member, a notch, or the like. Next, the two positions h, h'; f, f' are, for example, links 13, etc. that constitute a lifting mechanism for the floor part 11 of the bed 10, etc., as shown in FIG. Fourth
As shown in FIG. The above-mentioned two positions are configured in the screw shaft type telescoping device 17 for driving, so that the two positions correspond to the head side H and the foot side F of the floor part 11, and the intervals are set in accordance with the elevation of the respective sides H and F. Any two positions may be used as long as the two positions change. Furthermore, an appropriate elevating mechanism for elevating the head side H and foot side F of the floor portion 11 can be selected as appropriate.

(Function) In the configuration shown in FIG. 1, if both the head side H and the foot side F of the floor section 11 are in a downward state as shown by the solid line c in FIG. Both the display member 1a corresponding to the head side H and the display member 1b corresponding to the foot side F are spring means 9a, 9b.
The reference indicators 6a and 6b are located to the left of the window 12 as shown in FIG. It can be seen that the support heights of the head side H and foot side F of 11 are the same, that is, that they are supported in a horizontal state, and these reference displays 6a, 6
It can be seen that the floor portion 11 is supported at a low position by the scale 8 corresponding to the amount of elevation of the container body 2 corresponding to the position b.

Next, the floor portion 1 is
If only the cranial side H of wire 1 is raised to bring it into the state shown by the imaginary line in FIG. Since it is pulled, the display member 1a and the reference display 6a move to the right as shown in FIG. 2b. Therefore, it is possible to read how far the head side H of the floor portion 11 has risen, that is, the amount of elevation or height, by the scale 8 corresponding to the amount of elevation of the container body 2 corresponding to the position of the reference display 6a. By reading the angle corresponding scale 7 corresponding to the difference between the reference displays 6a and 6b, it is possible to know the difference in support height between the head side H and foot side F of the floor section 11 and the inclination angle of the floor section 11. can. Contrary to the above, from the state of the solid line in FIG.
When the display member 1b and the reference display 6b move to the right as shown in FIG. 2c, as shown in the virtual line in FIG. Similarly, the support heights of the head side H and foot side F of the floor section 11 and the inclination angle of the floor section 11 can be known.

Next, from the state shown by the solid line in FIG. 1c, both the head side H and the foot side F of the floor 11 are raised to the state shown by the imaginary line in FIG. If it moves to the right as shown in Fig. 2d, and both reference displays 6a and 6b match, the support heights of the head side H and foot side F are the same and the support is in a horizontal state. I found out that there was a vessel 2.
It can be seen that the floor portion 11 is supported at a high position by the scale 8 corresponding to the amount of elevation. As described above, in the present invention, the floor part 1 is
To check whether or not the floor part 11 is inclined, as well as the amount of elevation of the head side H and the foot side F of the floor part 1, that is, the support height, and the angle of inclination without directly looking at the floor part 11 itself. This is possible. Since the two positions h, h'; f, f' and the vessel body 2 are connected by the wire devices 5a, 5b, their relative positions can be set as appropriate. The body 2 can be easily installed at a position where the display can be easily seen when the floor section 11 is raised and lowered, and the operation of raising and lowering the floor section 11 becomes very easy. For example, when the screw shaft type telescoping device 17 is driven by the crank handle 18, the container body 2 is attached to the floor support frame 1.
If the window 12 is configured on the outside by also serving as the frame member 20 in the transverse direction of the crank handle 1.
8, the raising/lowering and inclination state of the floor part 11 can be checked at the same time, and the raising/lowering operation is very easy and hassle-free. In the above description, the direction in which the inner wires 4a and 4b are pulled is defined as the upward direction of the floor portion 11, but it goes without saying that the direction may be opposite to this. Further, the specific structure of the floor portion 11 may be any suitable structure, such as a structure in which it is made up of a plurality of divided parts and can be raised and lowered as shown in the illustrated example, or a structure in which it is simply planar. In the former case, the floor portion 11 in the above description is shown as a whole rather than each part.

(Effects of the invention) As described above, the present invention, in a bed etc. that can be raised and lowered and tilted, allows a pair of display members movably supported in parallel to the container body to move in the direction of inclination of the floor of the bed, etc. It is possible to confirm the inclination angle as well as the amount of elevation of both sides by moving the device in accordance with the amount of elevation of both sides, for example, the head side and the foot side, and displaying the display by the pair of display members corresponding to the amount of movement. With this configuration, it is possible to easily reproduce the desired elevating position, inclination, and horizontal state, and the elevating mechanism for moving the display member in accordance with the elevating amount is provided. Since the two positions and the vessel body are connected by a wire device, the installation position of the vessel body can be set appropriately. This has the advantage that the display can be easily installed in a position where it can be easily seen at all times, and the operation can be performed very easily. In addition, if the distance between the two positions and the amount of movement of the display member with respect to the amount of elevation are not linear, it may be corrected by adjusting the scale etc. described above, and slight non-linearity may be ignored. You can.
