Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pediatric bed which can be supported at an arbitrary position by sliding a full-face fence covering the entire side surface.

[0002]

2. Description of the Related Art For example, in a crib, since the patient is a child, safety has been particularly emphasized. For example, side fences, etc., which have a structure such as a plug-in type that can be seen in a normal bed, and a structure that only partially covers, are not adopted. The fence is adopted. In this case, the full-face fence has a function of being able to move up and down along the support of the bed, and has a function of arbitrarily holding the height of the side fence by the height adjustment holding mechanism. Since the side fence can completely cover the side surface of the bed, it is possible to prevent children from falling and there is no problem in terms of safety. Further, since the height adjustment holding mechanism allows the side fences to be held in a stepwise manner, there is no hindrance when getting on or off the bed, treating, or the like.

[0003]

However, according to the pediatric bed as described above, the side fences are configured to be lifted and lowered along the bed pillars. It was necessary to attach the legs and the main frame in order to keep the sliding part in a highly accurate state so that it would not occur. Further, since the height adjustment holding mechanism can support the side fence only at a position of a certain level, there is a demand for a mechanism capable of finely adjusting the height. In addition, the height adjustment mechanism was designed to slide the side fence to the locking position to the position where the locking member is located while lifting it by hand, so release the side fence to the locking position. It is difficult to operate without having to operate it. Further, when the casters are attached to the legs, a horizontal rail is provided near the lower end of the leg column, and the casters are provided on the horizontal rail. Therefore, during transportation, there is a problem that the foot or the like hits the cross rail and is difficult to carry. The present invention has been made in view of the above problems, and an object of the present invention is to provide a pediatric bed in which the holding height of the side fence can be freely adjusted.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a slide rail along a leg column and a slider at each end of an upper cross rail of a side fence. One end of a movable supporting arm curved in an L shape is attached to the lower horizontal rail, and a cylinder side of a gas spring for supporting the movable supporting arm at an arbitrary position is attached to the movable supporting arm, An operation pedal for unlocking the gas spring is provided on the rod side of the gas spring. Further, in the pediatric bed, the main frame and the leg support are configured to be locked via a hook-shaped member. Further, a transport caster is attached to the tip of the leg column.

[0005]

[Operation] When the side fence is lifted and the height is adjusted to a desired position, the side fence is pulled up and the upper part of the side fence slides on the slide rail. Then, the movable support arm attached to the lower part of the side fence is also displaced upward, and the rod of the gas spring is projected. At this time, even if the hand is removed from the side fence, the gas spring is locked, so that the side fence is held at that position. When lowering the side fence, depressing the release operation pedal while holding the side fence by hand releases the locked state of the gas spring, and the rod retreats into the cylinder as a buffer. If the operation of the release operation pedal is interrupted on the way, the rod is locked and fixed, so that the side fence is held at that position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a child's bed according to the present invention will be described below with reference to the accompanying drawings with reference to an embodiment. In FIG. 1, reference numeral 1 denotes a pediatric bed, and the pediatric bed 1 is provided with a head fence 3 and a foot fence 4 between a pair of leg columns 2 and these head fence 3 and foot A main frame 6 on which a bottom part 5 is placed is attached to the leg support 2 that holds the fence 4, and a side fence 7 that covers the entire side surface of the main frame 6 is provided. is there.

As shown in FIG. 2, the side fence 7 includes a slide rail 8 attached to the leg support 2 and an upper cross rail 9 of the side fence 7.
It is configured to slide up and down via the sliders 10 attached to both ends of the. Further, one end of an L-shaped movable support arm 12 is pivotally attached to the lower cross rail 11 of the side fence 7, and further, the movable support arm 12 is movably supported as shown in FIG. A cylinder 14 side of a gas spring 13 for supporting the arm 12 at an arbitrary position is attached, while a release operation pedal 16 is provided on the rod 15 side of the gas spring 13.

The gas spring 13 has a function of locking the rod 15 at an arbitrary position, and has a mechanism for releasing the locked state by the release operation pedal 16. That is, although not shown, the cylinder 14
Gas is sealed inside through a fluid (oil) and a movable shielding wall, and a piston attached to one end of the rod 15 on the oil chamber side blocks the oil in the cylinder 14 into two chambers. It is provided. The piston is provided with a passage for circulating the oil in the two chambers, and a valve body for opening and closing the passage is provided, and a push rod 17 for moving the valve body penetrates the rod 15 so that The tip projects to the position of the release operation pedal 16 and is linked by the operation of the release operation pedal 16.
(See Figure 4).

In the infant bed 1, the main frame 6 and the leg support 2 are engaged with each other via a hook-shaped member 18. Further, a transport caster 19 is attached to the tip of the leg support 2.

The pediatric bed 1 according to the present invention is constructed as described above. Next, its operation will be described. When the side fence 7 is lifted and the height is adjusted to a desired position, when the side fence 7 is pulled up, the upper side fence 7 slides on the slide rail 8. Then, the movable support arm 12 attached to the lower part of the side fence 7 is also displaced upward, and the rod 15 of the gas spring 13 is projected. At this time, even if the hand is removed from the side fence 7, the side fence 7 is held by the gas spring 13 (see FIG. 5).

When lowering the side fence 7, when the operator operates the releasing operation pedal 16 while holding the side fence 7 by hand, the push rod 17 is pressed to release the locked state of the rod 15, and the rod 15 is buffered. Retreats into the cylinder 14. If the operation of the release operation pedal 16 is interrupted on the way, the rod 15 is locked again and fixed, so that the side fence 7 is held at that position (see FIG. 6).

By the way, when the side fence 7 moves up and down, the sliding rail 8 is slid up and down through the slider 10, so that the distance between the head fence 3 and the foot fence 4 is highly accurate. It is not always necessary, and therefore, the main frame 13 and the leg support 2 may be locked via the hook-shaped member 18. Further, since the casters 19 are directly attached to the lower ends of the leg columns 2 that support the head fence 3 and the foot fence 4, there is no need for a horizontal rail for attaching the casters as in the conventional case. Therefore, when carrying the pediatric bed 1, there is an effect that it is easy to carry, without hitting the legs.

[0013]

As described above, according to the present invention, the side fence can be held at an arbitrary position by the gas spring 13, and the positional relationship of the sliding rail for sliding the side fence can be improved. Since the accuracy does not need to be so important,
Since the mounting process is simple and a cross rail for mounting the casters is not required near the lower end of the leg support 2, as a result, there is no problem such as hitting a foot during transportation,
This has the effect of greatly improving transportability.
