Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lifting side fence in a bed or the like which can be supported at any position.

[0002]

2. Description of the Related Art For example, in a pediatric bed, since the patient is a child, the side fences have a structure such as a plug-in type which can be seen in an ordinary bed and a structure which only partially covers. Nothing has been adopted, but a so-called full-scale fence that can completely cover the side of the bed has been 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 gradually supporting the height of the side fence by the height adjustment support mechanism.
According to such a side fence, since the side surface of the bed can be completely covered, it is possible to prevent children from falling,
There is no problem in terms of safety. Further, since the height adjustment support 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 elevating side fences in the bed or the like as described above, the side fences are configured to be elevated and lowered along the bed pillars. It was necessary to attach the legs and the main frame so that there would be no misalignment. Further, since the height adjustment support mechanism can support the side fence only at a certain level of position, there has been a demand for a height adjustment support mechanism that can be finely and freely adjusted. Also,
The height adjustment mechanism was designed so that while lifting the side fence by hand, it slides to the place where the locking member is located and locks it. It was necessary and difficult to operate. Therefore, it is difficult for the nurse to perform the lifting operation of the side fence while holding the medical device in one hand. The present invention has been proposed from such a background, and an object thereof is to provide an elevating side fence in a bed or the like that can be easily operated with one hand and the holding height of the side fence can be freely adjusted. And

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a bed with guide rail portions on the surfaces of the leg columns on the head side and the leg side of the bed that face each other. Elevating side fences that can be moved up and down along the guide rails of the leg columns on the head side and the leg side are provided, and these raising and lowering side fences are raised and lowered along the guide rails at both ends of the upper horizontal rail. a guide portion for moving provided, the guide Les

[0005]

When the side fence is pulled up by holding the upper side rail, the guide portions at both ends of the upper side rail of the side rail slide on the guide ribs of the guide rail portion. At this time, the slider in the case receives a force to drop against the spring force, and the roller member contacting the plate from the slider side surface moves to a position below the plate that spreads in the lateral width direction.
The force that tries to roll against the abutting force on the plate overcomes and rolls, so that it can be lifted. Here, when the side fence is released, the case tries to fall downward together with the side fence due to the weight of the side fence, but the slider receives a force by the spring force so as to project above the case. Therefore, the roller member also receives a force on the side that moves upward,
The roller member is sandwiched between the guide ribs and the plate, and as a result, the guide portion is locked, so that the side fence is held at that position. When lowering the side fence, the operation lever is operated to rotate the cam shaft to interlock the cam member, and the slider is interlocked to push downward against the spring force. Since the roller member is moved to a position below the plate that spreads in the widthwise direction, the roller member is separated from the plate and becomes free, so that the locked state is released and the side fence can be lowered.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an elevating side fence in a bed or the like according to the present invention will be described below with reference to the accompanying drawings with reference to an embodiment. FIG. 1 shows a pediatric bed 1,
This pediatric bed 1 has an entire surface fence 2 that covers the entire side surface of the bed. The full-surface fence 2 is composed of upper and lower horizontal rails 3 and 4 and a large number of vertical rails 5 arranged at regular intervals. It has a structure that can be held.

That is, as shown in FIG. 2, the full-scale fence 2 has a height adjustment support mechanism 6 for holding it at an arbitrary height.
The head side and the leg side of the bed are formed as guide rail portions 8 by opening the mutually facing surfaces of the hollow leg strut 7 on the head side and the leg side. 9 are provided and mounted on these guide rail portions 8 via the guide portion 9 so as to be movable up and down. The guide rail portion 8 has an E-shaped cross section, and the surfaces of the leg columns 7 on the head side and the leg side of the bed facing each other are defined as the opening surfaces 10, and the guide rail portions 8 are provided so as to project toward the opening surface 10 on the inside. It has a guide rib 11. On the other hand, the guide portion 9 is inserted into the guide rail portion 8 through the opening surface 10 and the case 12 is inserted.
And a slider 13 built in the case 12, and in order to allow the slider 13 to be movably fitted in the guide rib 11 via the case 12, the case 12 and the slider 1
3 are provided with grooves 14 and 15, respectively.

Next, the full-face fence 2 having the above structure
The height adjustment support mechanism 6 for holding the height at an arbitrary height will be described. The height adjustment support mechanism 6 can move freely in the direction of lifting the whole surface fence 2 and has a mechanism for supporting the whole surface fence 2 at the lifted position even when the hand is lifted at the time of lifting and the whole surface fence by this mechanism. It has a mechanism for canceling the function of supporting 2. That is, in the guide portion 9, the case 12 has a space portion 16 for accommodating the slider 13 having a trapezoidal cross section on the upper side, and a plate 17 having a trapezoidal outer shape is fitted into the space portion 16 on the upper side. I have to. The slider 13 is supported on the case 12 by a spring member 18. Further, a roller member 19 is rotatably mounted on the upper side surface of the slider 13. The roller member 19 is in contact with the guide rib 11 via the groove 15 provided in the slider 13, and the trapezoidal plate 1 via the space 16.
7 is abutted (see FIG. 3). further,
As shown in FIG. 4, the slider 13 includes an upper horizontal rail 3
A cam member 21 attached to one end of the rotating shaft 20 inserted inside is in contact with the slider 13. An operating lever 22 is provided on the rotary shaft 20 for passing the inside of the upper horizontal rail 3 and giving a turning force to the rotary shaft 20 at an intermediate portion of the upper horizontal rail 3.
Are connected (see FIG. 2).

The elevating side fence 6 in the bed or the like according to the present invention is constructed as described above. Next, its operation will be described. If you pull up the front fence 2,
The slider 13 in the case 12 in the guide portion 9 receives a force so as to fall against the spring force of the spring member 18, which causes the roller member 19 to shift to a position below the expanding plate 17, The roller member 19 is the plate 1
The force that tries to roll against the abutting force against 7 wins and becomes a state in which it can roll, and the guide portions 9 at both ends of the entire surface fence 2 slide on the guide ribs 11 of the guide rail portion 8 to lift the entire surface fence 2. You can At that time, it is not necessary to operate the operation lever 22, and one-handed operation can be easily performed.
Further, in this case, the protruding portion of the cam member 21 that is in contact with the slider 13 is separated from the portion that is in contact with the slider 13 so that the cam member 21 does not apply a pressing force to the slider 13.

Here, when the hand is released from the full-face fence 2, the guide portion 9 tries to fall downward due to the weight of the full-face fence 2, but the slider 13 moves upward in the case 12 by the spring force of the spring member 18. As a result, the roller member 19 also shifts to the top side of the plate 17, so that the roller member 19 is sandwiched between the guide rib 11 and the plate 17, and as a result, the guide portion is formed. Since 9 is locked, the front surface fence 2 is held at that position (see FIG. 5).

When lowering the entire surface fence 2, the operation lever 22 is operated to rotate the rotary shaft 20 to rotate the cam member 2.
1 is interlocked and the slider 13 is pushed downward against the spring force by the protruding portion of the cam member 21 (see FIG. 6). It shifts to the position, the pressure contact force of the roller member 19 to the plate 17 is removed, the lock is released, and the entire surface fence 2 can be lowered (see FIG. 7).

[0012]

As described above, according to the present invention, when the side fence is lifted, it is not necessary to operate the operation lever, and the nurse can carry out the operation while holding the medical instrument in one hand. Even if you lift and remove the fence, it will be locked and can be held at that position, so even if you release your hand on the way, it will not return to the original position, and you will lift it again from the position where it was stopped and Since the holding height can be adjusted freely, the operability is greatly improved. In addition, when the side fence is lowered, it can be easily lowered by operating the operation lever to release the locked state, which greatly improves the usability.
