Description

[Detailed description of the invention] "Field of industrial application" The present invention relates to a patient scooping machine.

``Prior art'' As a device for mechanically scooping up a patient lying supine on a bed, two blades are placed close to each other vertically, and a driving pulley and a guide pulley are placed behind each blade. A belt is stretched between the blade, the driving pulley, and the guide pulley, and each belt is equipped with a belt tensioner, so that both belts rotate at the same speed in forward and reverse directions, and this rotation causes the blade and belt to There is something that you insert between the patient and the bed and scoop it up.

``Problems that the invention aims to solve'' However, with conventional belts, belts tend to loosen under heavy loads, and there are variations in upper and lower belt tensions, so long-term smooth operation cannot be expected. It was hot. In addition, the belt tensioner takes up a considerable amount of space, making the device large, making it difficult to handle in a narrow hospital room, and increasing costs.

Therefore, the present invention aims to eliminate these drawbacks and to provide something even better.

"Means for solving the problem" The present invention arranges two blades close to each other vertically, a driving pulley and a guide pulley behind both blades, and connects each blade to the driving pulley and the guide pulley. In a patient scooping machine, which is configured such that a belt is stretched between each guide pulley and both belts are rotated at the same speed in forward and reverse directions, the support shafts of both guide pulleys are attached to the tips of the levers. The bases of these levers are mechanically and equally pivotally connected to the frame, and springs are appropriately interposed between both levers to urge them both in common.

"Example" In the figure, 1a and 1b are two blades arranged close to each other vertically, made of a material with a small coefficient of friction, with a plurality of spacers interposed at appropriate places between them, and thin blades on both sides. Side plates 2, 2 are attached and integrated. Further, one insertion guide 3 is installed horizontally just in front of both blades, and this insertion guide is supported by the front end of the blade and the front ends of the side plates 2, 2.

Reference numerals 4a and 4b denote two driving pulleys disposed behind both blades 1a and 1b, which are arranged close to each other in parallel and are supported by the left and right frames 5, 5. The length of both driving pulleys corresponds to the width of both blades 1a, 1b, and the rotating shafts 6a, 6b of both driving pulleys are equipped with equal gears 7a, 7b so that both rotate at the same speed in forward and reverse directions. A reversible deceleration motor 8 is connected to one rotating shaft 6a.

9a and 9b are guide pulleys arranged between the rear ends of both blades 1a and 1b and both driving pulleys 4a and 4b.The length of both guide pulleys corresponds to the width of both blades, and the support shafts are connected to each other at both ends. 10a, 10a, 10b, and 10b so as to be rotatable, and placed in parallel with both driving pulleys.

11, 11 are a pair of left and right levers connected to the support shafts 10a, 10a at both ends of one guide pulley 9a, and 12, 12 are connected to the support shafts 10b, 10b at both ends of the other guide pulley 9b. These are a pair of left and right T-shaped levers that are connected, and these levers have tip portions 111, 111, 121, 1
21 to the support shaft, and the base 112, 112, 1
22, 122 is vertically above the frame 5, 5
is pivotally supported by pins 13, 13, 14, 14,
Therefore, the guide pulleys 9a and 9b are held movably in the front and back direction. In addition, pins 13, 1
3, 14, 14 to support shafts 10a, 10a, 10
The distances to b and 10b are both equal.

15 is a lever 11, 1 having an F-shape and a T-shape.
Empty piece 113, 113, 1 in 1, 12, 12
A compression spring is interposed between 23 and 123, and this spring is equipped with flanges 16, 16 at both ends, and the flanges are slidably fitted into a guide pin 17 installed between the protrusions. Further, the guide pin 17 has one end pivotally supported by one of the protruding pieces 123, 123, and the other end slidably penetrating (through-hole) the other protruding piece 113, 113.

The side plates 2, 2 and the frames 5, 5 are connected by bolts 19, 19, 19, 19 on the left and right, and the bolts are screwed into the side plates 2, 2 located on the inside, and the frames 5, 5 on the outside, 5 is provided with horizontal elongated holes 51, 51, 51, 51, through which bolts are loosely inserted to enable position adjustment. 5
Reference numerals 2 and 52 indicate window holes for inserting support shafts, which are bored in each of the frames 5 and 5.

18a..., 18b... are the upper and lower blades 1, respectively.
These are a plurality of belts stretched between a, 1b, driving pulleys 4a, 4b, and guide pulleys 9a, 9b. There is a slight gap between the upper and lower belts to reduce friction between the belt and the blade due to load.

20, 21, and 22 are covers that enclose each part.

"Operation" Since the above configuration is as described above, if the reversible reduction motor 8 is rotated in the forward direction, the driving pulleys 4a, 4
The belts 18a..., 18b... rotate in the retracting direction via the blades 18a and 18b (solid line arrows in Figure 4), so that the belts and blades 1a and 1b can be inserted between the patient and the bed. Can scoop up patients. Furthermore, by rotating the reversible deceleration motor 8 in the reverse direction, the belt rotates in the feeding direction (dotted line arrow in Figure 4), so that the patient on the belt can be transferred to the bed.

Thus, the compression springs 15, 15 spring both guide pulleys 9a, 9b rearward via the F-shaped and T-shaped levers 11, 11, 12, 12, and both belts 18a..., Common tension is given to 18b...

``Effects of the invention'' According to the invention, the tension of both the upper and lower belts can be always balanced, and belt loosening can be minimized, making it possible to obtain smooth operation over a long period of time. becomes.

In addition, the mechanism can be significantly simplified and miniaturized.
It is easy to handle in a narrow hospital room, and assembly and adjustment are extremely easy, reducing costs.
