Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a fence that is attached to a supine table such as a bed, patient carrier, or examination table to prevent the user or bedding from falling. .

(Prior art) For example, as a fence installed on the longitudinal side of a bed to prevent the user or bedding from falling, for example,
This is disclosed in Publication No. 45183. As shown in Fig. 3, this fence is constructed by connecting a fence main body a and a side member b of the bed with a pair of support arms c and c' so as to form a parallel link mechanism in the inside and outside directions of the bed. The fence main body a is moved up and down in parallel by the support arms c and c', and is in a used state in the upper position and in an unused state in the lower part.

(Problem to be solved by the invention) However, the above-mentioned conventional configuration
and side member b of the bed constitute a parallel link mechanism in the inward and outward directions of the bed with the support arms c and c', so that when the fence body a moves up and down, it also moves in the inward and outward directions of the bed. However, when the fence body is moved up and down, it protrudes outward from the bed compared to the position in the used state or in the non-used state. In recent years, in patient rooms in hospitals, etc., there are many ME devices placed around the beds, and in this case, if the main body of the fence protrudes outward while being raised or lowered, there is a risk of hitting such ME devices. There are also problems such as difficulty in operation when multiple beds are installed adjacent to each other and the space is narrow. The present invention aims to solve such problems in the prior art, and will be described in detail below based on examples.

(Means for Solving the Problems) Reference numeral 1 indicates a side portion of the supine table, 2 indicates a floor portion, and 3 indicates a floor support frame. The supine table may be a bed, a patient carrier, an examination table, or the like as appropriate, and the configurations of the floor 2 and floor support frame 3 may also be appropriate. Therefore, a pair of guide parts 4, 4 are provided on the side part 1 of the supine table, each of which supports a support member 5 movably in and out of the supine table, and each of the support members 5 has a support arm. 6
One side is rotatably supported, and the other side is rotatably supported on the fence body 7. In addition, actuating arms 8 are rotatably supported at positions on the side part 1 of the supine table outside one side of the supporting arms 6, and the distal ends of the actuating arms 8 are connected to the intermediate portions of the supporting arms 6. Connect in place. Furthermore, an upright part 9 is provided on at least one side of the support member 5 of the pair of guide parts 4, and one side of the interlocking support arm 10 is rotatably supported on this upright part 9, and the interlocking support arm 10 The other side of the support arm 10 is supported by the fence body 7 so as to constitute a parallel link mechanism together with the support arm 6, the support member 5, and the fence body 7. In the embodiment shown in the figure, the guide part 4 has a member 12 formed with a guide elongated hole 11 at the short side end of the floor support frame 3 so that the elongated hole 11 is in the inner and outer directions of the supine table. The supporting member 5 has a support piece 13 on the lower side facing the elongated hole 11, and a plurality of points in the elongated hole 11 direction of the support piece 13 are connected with stepped bolts 14. It is movably fixed along the elongated hole 11. In addition, the structure of the guide part 4 and the specific structure of supporting the support member 5 on this guide part 4 are arbitrary. Next, the fence main body 7 has the support arm 6,
As long as a parallel link mechanism can be formed together with the support member 5 and the interlocking support arm 10, the specific structure thereof, such as a lattice shape or a plate shape, is suitable, and this parallel link mechanism does not have to be a completely parallel link mechanism. Of course.
Next, in the illustrated embodiment, the actuating arm 8 is connected to the interlocking rod 1.
By protruding from both ends of the actuating arm 8 and rotatably fixing the interlocking rod 15 to the member 12, the actuating arm 8 is configured to be rotatable. This interlocking rod 15 is not essential, and the actuating arm 8 may be directly fixed to the member 12, etc., but if the interlocking rod 15 is provided, both sides of the pair can be interlocked well, and the operation can be performed smoothly. be able to.

(Function) In the above configuration, by fixing the fence main body 7 in the upper position with an appropriate stopper mechanism 16 as shown in FIG. 2a, it is possible to prevent users such as patients and bedding from falling. . By releasing the stopper mechanism 16, the support arm 6 can be rotated downward and the fence body 7 can be lowered. At this time, the fence main body 7 is lowered in parallel by a parallel link mechanism constituted by the support arm 6, the interlocking support arm 10, and the support member 5. This parallel link mechanism may be constructed only on one side of the fence body 7 as in the embodiment shown in the figure, or it may be constructed on both sides. As the supporting arm 6 rotates downward as the fence main body 7 descends, the operating arm 8 also rotates downward. Depending on its installation position, the distal end of the actuating arm 8 gradually moves inward of the supine table as it rotates downward, so the support arm 6 connected to the distal end is also actuated inward, thus providing support. The member 5 moves inwardly along the guide 4 and the interlocking support arm 10 also moves inwardly. Actuation arm 8
The state shown in FIG. 2b where the supporting arms 6 and 6 are in the same direction is as follows.
The support member 5 is in the most inwardly moved state,
After this, when the fence main body 7 is further lowered, the support member 5 moves outward again. In this way, the fence body 7
The patient can be brought to the lowest position, allowing patients to get on and off the floor 2, and to perform examinations, treatments, and the like. Then, the fence body 7 can be raised by the reverse operation to the above, and can be fixed again by the stopper mechanism 16 to be in use. The stopper mechanism 16 in the illustrated example is operated by fitting a stopper pin fixed to the fence body 7 that can move forward and backward into a stopper hole 17 formed in the support arm 6 by the elasticity of a spring, and can be released by an operation knob 18. However, the stopper mechanism 16
The specific configuration of is arbitrary.

By the way, in the above operation, if we consider the case where the operating arm 8 is not provided and the support member 5 is in a fixed state, the fence body 7 moves in the inward and outward directions of the supine table when going up and down, and the support arm 6 It protrudes most outward in the horizontal direction. However, in the present invention, as described above, the operating arm 8 is provided, and the support member 5 is also provided.
is configured to be movable in the inner and outer directions, and the fence main body 7
When moving up and down, the support member 5 is moved in the inward and outward directions to cancel out the movement of the fence body 7 in the inward and outward directions. It is possible to raise and lower the table without moving it at all or with a slight movement in the inside and outside directions of the table.

(Effect of the invention) As described above, the invention provides support arms and/or support arms for the fence body.
Or a support member supported via an interlocking support arm,
By providing an actuating arm on the side of the supine table that is movable in the medial and medial directions and that moves the support member via the support arm, the movement in the medial and medial directions when the fence main body is raised and lowered is canceled out. Because of this, the main body of the fence can be raised and lowered with little or no protrusion, making it easy to operate even when the supine table is placed in a narrow hospital room, etc. It is also possible to effectively prevent the fence itself from colliding with ME equipment and causing damage. The fence of the present invention can be constructed not only on the long sides of the supine table, but also on the short sides as the case may be, and can also be used as a footboard or a headboard.
