Description

[Detailed Description of the Invention] This invention relates to a reclining type stretcher on both sides provided with a ratchet mechanism for changing the tilt position.

[Prior Art] Stretchers used to move sick people, bedridden elderly people, or patients after surgery within a ward are installed on the bathroom floor so that patients can take a simple bath while carrying them. Some bathtubs have a structure that allows you to step over a lift-type bathtub. The reclining type stretcher 1 shown in FIG. 5 has a frame structure roughly M-shaped when viewed from the side, and is supported by four legs 2 supported by casters 2a.
A support plate 3 consisting of a seat portion 3a and a backrest portion 3b is supported.

The backrest part 3b is in a horizontal state and 40 degrees with respect to the horizontal state.
It can take two postures that are tilted at the same time, and these postures are locked by inserting and removing a tilt angle locking pin (not shown).

When placing a patient on the stretcher 1, first, the backrest portion 3b locked to the frame 4 is laid down horizontally, and then the frame 4 is tilted toward the front. In this way, when the seat part 3a and the backrest part 3b are flush with each other and there is no obstruction on the upper surface, the patient on the bed or stretcher is moved laterally and placed on the patient.

The patient placed on the stretcher 1 is placed in an elevating bathtub (not shown) with the backrest 3b raised.
The bathtub is carried directly above the bathtub, and the bathtub rises from below, allowing the user to bathe while lying down.

[Problems to be solved by the invention] The above conventional reclining type stretcher 1
In this case, the inclination angle of the backrest part 3b is horizontal and 40 degrees.
If you want to set the inclination angle to 40 degrees, you must replace the inclination angle locking pin, which is a very tedious task. There were problems in that the frame 4 on the side of the section 3b had to be tilted toward the front, and that the frame 4 had to be handled with care.

Furthermore, the conventional reclining stretcher 1 described above has a structure in which once one patient gets on it, no more people can sit on it, regardless of whether the patient is an adult or a child. When moving using the stretcher 1, there were problems such as taking too much time.

[Means for solving the problem] This invention solves the above problem, and includes a central seat part and a pair of backrests supported from both sides by legs with casters, and pivoted on both sides of the central seat part. The present invention is characterized in that it is constructed by providing a support plate consisting of a plurality of sections, and a ratchet mechanism that is provided for each of the backrest sections and that adjusts the tilted posture of the backrest section at a plurality of locations.

[Function] This device pivots a backrest part with a variable inclination angle on both sides to the central seat part of a support plate supported by legs on both sides, so that two patients can sleep in alternating directions. At the same time, the inclination of the backrest part can be changed individually and easily by a ratchet mechanism.

[Example] Hereinafter, an example of this invention will be described with reference to FIGS. 1 to 4. Figures 1 and 2 are a plan view and a perspective view, respectively, showing an embodiment of the double-sided reclining stretcher of this invention, and Figures 3 and 4.
The figures are a partially sectional plan view and a partially sectional side view of the ratchet mechanism shown in FIGS. 1 and 2, respectively.

In Figures 1 and 2, the reclining stretcher 11 on both sides has four legs 1 with casters 12a.
2 supports the support plate 13, and the support plate 13 is
a seat part 13a that supports the patient's lower body; a pair of backrest parts 13b whose inclination angle can be changed at will;
Consisting of 13c. The backrest portions 13b and 13c are
It is rotatably connected to both sides of the seat portion 13a,
Each has a pillow 14 that supports the patient's head.
Therefore, in the case of children, two people can sleep side by side with their heads resting on the pillows 14.

A ratchet bar 15 is attached to one side of each backrest portion 13b, 13c, and a ratchet mechanism 16 is operated by the ratchet bar 15.
b, 16c, the backrest portions 13b, 13c can be fixed at a desired inclination angle.

In this embodiment, both ratchet mechanisms 16b, 1
Reference numeral 6c has the same structure, and here, the structure and operation thereof will be explained using one ratchet mechanism 16b as an example.

As shown in FIGS. 3 and 4, the ratchet mechanism 16b includes a locking plate 18 formed in a semicircular arc around a shaft 17 connecting the seat portion 13a and the backrest portion 13b.
It consists of a box-shaped holder 19 which is pivotally supported by a shaft 17 and fixed to the ratchet bar 15, and a claw part 20 which is movable within the holder 19.

The locking plate 18 passes through the inside of the holder 19,
A plurality of locking grooves 18a are carved in a sawtooth shape on the inner peripheral side thereof. On the other hand, the claw portion 20 is connected to the locking groove 1.
8a, and has a shape that engages with the ratchet bar 15.
With the displacement of the rod 21 passing through the locking groove 1.
engages or disengages from 8a. The tip of the rod 21 is inserted through a cylindrical grip 22 fitted to the tip of the ratchet bar 15, and a cap 23 placed over the tip of the rod 21 extends outward from the grip 22. There is. A spring 26 is fitted in the grip portion 22 and applies a force to the cap 23 in the direction in which the claw portion 20 engages with the locking groove 18a.

In this embodiment, handrails 24 for preventing falls are removably attached to both sides of the seat 13a and the backrests 13b and 13c.
A removable footrest 25 is attached to the central part of a. The footrests 25 are a hindrance except when a child is riding, so they are usually removed.

Here, when changing the inclination angle of the backrest part 13b or 13c, first press the palm of your hand against the cap 23, press the rod 21, and press the grip part 22.
Clutch it. Since the claw portion 20 separates from the locking groove 18a as the rod 21 is pushed in, the holder 19 can freely change its position with respect to the locking plate 18. Therefore, by moving the entire ratchet bar 15 with the hand holding the grip portion 22, the inclination angle of the ratchet bar 15 and the backrest portion 13b can be changed.

When the backrest portion 13b reaches a desired inclination angle, the pushing of the rod 21 is released and the claw portion 20 is locked in the locking groove 18a by the restoring force of the spring. This allows the backrest portion 1 to be adjusted at a desired inclination angle.
3b can be locked.

If the inclination angle is to be increased while the patient's weight is still on the backrest portion 13b, the hand holding the grip portion 22 may be pulled up without pushing the rod 21. By doing this, the claw portion 20 naturally separates from the locking groove 18a along the inner wall of the locking groove 18a, and connects to another locking groove 18 at an appropriate position.
a and stops. Conversely, if you try to push down the grip part 22 without pushing in the rod 21, the claw part 20 cannot be released from the locking groove 18a, so the backrest part 13
It is possible to prevent accidents such as falling of item b.

Further, the posture change of the backrest portion 13c is the same as that of the backrest portion 13b, and the ratchet bar 15 is
Since it is always displaced together with the backrest portions 13b and 13c, it does not interfere with the patient's getting on and off.

In this way, in the double-side reclining stretcher 11, the support plate 13 supported by the leg parts 12 on both sides is roughly composed of three parts: the central seat part 13a and the backrest parts 13b and 13c on both sides. For small children, etc., it is possible to sleep with the head and feet alternately arranged, increasing the efficiency of work such as moving around and bathing.Moreover, each of the backrest parts 13b and 13c can be adjusted to several levels separately. The inclination angle can be changed using ratchet mechanisms 16b and 16c that can be operated with one hand, so that the user can easily tilt the backrest 13b or 13c even when the weight is on the backrest 13b or 13c. Since the inclination of the patient 13c can be changed and there is no need for a frame 4 or the like that would be an obstacle for patients getting on and off, the work of transferring patients etc. is extremely simple.

[Effects of the invention] As explained above, according to this invention, the support plate supported by the legs on both sides is roughly composed of three parts: the central seat part and the backrest parts on both sides.
For small children, etc., it is possible to sleep with the head and feet alternately lined up, increasing the efficiency of tasks such as moving around and bathing.Moreover, each backrest can be individually tilted to several levels. A ratchet mechanism that can be operated with one hand allows the user to change the inclination angle, allowing the user to easily change the inclination of the backrest even when the weight is still on the backrest. Since there is no need for a frame or the like which would be an obstacle to getting on and off the patient, etc., it has excellent effects such as extremely easy transfer work of the patient, etc.
