Description

[Detailed description of the invention] The present invention provides a mechanism for tilting the floor of a bed, patient carrier, etc., which has a simple structure and can tilt the floor of a bed, patient carrier, etc. with an extremely small force. The detailed explanation is as follows.

Reference numeral 1 is the floor of the bed 2, patient carrier, etc.
The floor part 1 is fixed to a support frame 3 so as to be tiltable in the left-right direction around the central part of the floor part 1 in the longitudinal direction. This front-rear direction may be the longitudinal direction of the bed 2, etc. as shown in the illustrated embodiment, or may be the lateral direction. The support frame 3 is provided with a rotation shaft 4 in a direction perpendicular to the axis, and a support arm 5 is provided protruding from the rotation shaft 4. The support rods 6 are connected so as to be rotatable in the left and right direction.
As a method of connecting the support rods 6 so as to be rotatable in the front, rear, left and right directions on each side, for example, a spherical sliding surface such as a rod end may be installed between the ends of the support rods 6, the floor part 1 and the support arms 5. A structure in which a bearing or a universal joint is interposed may be used as appropriate. FIG. 4 shows an example of a structure in which a rod end 7 is interposed. That is, the rod end 7 is composed of an outer member 12 having a spherical sliding surface 11 and an inner member 13.
An insertion hole 16 is provided. Then, the rod ends 7 are attached to the mounting portions 1 at both ends of the support rod 6.
At the same time, the support rod 6 is connected between the support arm 5 and the floor part 1 via the rotation shaft 15 inserted through the insertion hole 16. Note that the code 17 is color, 1
8 is a mounting arm provided on the floor 1. In this configuration, the support rod 6 is rotatable in the front and rear directions by the rotation shaft 15, and can be rotated from side to side by relatively moving the outer member 12 and the inner member 13 along the spherical sliding surfaces. It can also be rotated in any direction. In the illustrated embodiment, the support arms 5 are provided in symmetrical positions with respect to the axis and protrude from the rotation shaft 4 in opposite directions.
Although the support rods 6 are connected between positions a and b equidistant from the axis of the floor portion 1, the support arms 5 and support rods 6 may be provided corresponding to only one side of the axis. Thus, the support frame 3 is provided with a drive mechanism A for the rotation shaft 4. If the drive mechanism A is a mechanism capable of rotating the rotation shaft 4, for example, as shown in the illustrated example, a drive arm 8 is provided protruding from the rotation shaft 4, and a drive arm 8 is provided between the drive arm 8 and the support frame 3. In addition to a mechanism provided with a screw shaft type telescoping rod 9, an electric motor 10 for driving the same, a crank handle, etc., any other suitable mechanism may be used.

In the configuration shown in the figure, when the telescoping rod 9 is shortened, the rotation shaft 4 rotates in the direction of the arrow in the figure, and the support arm 5 on the right side in the figure rotates upward, while at the same time the support arm 5 on the left side rotates upward. rotates and descends. Therefore, the right support rod 6 rises to raise the corresponding floor portion, that is, the portion on the right side of the axis, and at the same time, the left support rod 6 lowers to lift the corresponding floor portion, that is, the portion on the right side of the axis of the floor portion 1. By lowering the floor part 1, the floor part 1 can be tilted around the axis with the right side raised as shown in FIGS. 2a and 2b. If the telescopic rod 9 is extended in the opposite manner to the above, the floor part 1 can be tilted with the left side raised with the axis as a pivot point. During the above-mentioned tilting operation, the support rod 6, the floor section 1, and the support arm 5 rotate in the front-rear direction and also in the left-right direction at the same time. 1 are connected to each other so as to be rotatable in the front, rear, left and right directions, so the mechanism is not strained and operates smoothly. The above tilting operation is the same even when the support arm 5 and the support rod 6 are provided only on one side of the axis as described above.

As described above, in the present invention, the floor part 1 can be tilted in the left-right direction around the longitudinal axis of the central part, so if the longitudinal direction is the longitudinal direction of the bed 2, etc. It is possible to turn over a patient who is lying on his or her back, and on the other hand, in the case of transversal direction, it is possible to tilt the patient with one of the head side or the foot side upward as part of treatment. In such a case, since the present invention tilts the central part of the floor 1 around the longitudinal axis, the center of gravity of the patient, etc. is located close to this axis, and therefore the force required for tilting can be small. There is a characteristic that. Furthermore, the present invention has a simple configuration, and the tilting mechanism for the floor section 1 can be constructed using only the support frame 3 and one floor section. By configuring this, the floor section 1 can be operated in a further variety of ways. For example, as shown in the embodiment shown in FIG.
In addition, if the floor part 1 is supported so as to be tiltable in the front-rear direction, the floor part 1 can be adjusted appropriately in both the front-rear direction and the left-right direction as needed. If the floor part 1 is supported in a vertically movable manner on a base via the base, the floor part 1 can be tilted at an appropriate vertical position as described above.

This invention has an extremely simple configuration as described above, and
The floor section can be tilted with extremely small force, making it ideal for application to so-called floor rolling mechanisms and stretching mechanisms in beds and the like.
