Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a mounting structure for a side guard on a bed, and in particular, to a detachable mounting structure for a side guard suitable for medical beds.

BACKGROUND ART For example, some medical beds used in hospitals are equipped with side guards to prevent patients and bedding from falling. Such side guards often get in the way when preparing the bed or when a doctor examines the patient.Therefore, various structures have been developed that allow the side guards to be folded or rotated to be removed as desired. Proposed.

Problems that the invention attempts to solve This invention solves the problem by installing side guards as necessary.
The purpose of the present invention is to provide a bed side guard mounting structure that can be removed and rotated downward.

Means and Effects for Solving the Problems This invention has a structure in which side guards arranged along the longitudinal side of the bed connect bed posts provided at both ends of the longitudinal side. The attached structure of the bed side guard is characterized by the following points.

First, in order to allow the side guard to rotate outward and downward from the bed, the lower ends of both longitudinal ends of the side guard are pivoted horizontally to each bed post. They are connected by a pivot mechanism that includes a shaft and a bearing hole that receives the pivot shaft and is arranged substantially on the same axis.

In addition, in order to enable the side guard to be fixed in a state where it stands up along the bed post, the upper part of at least one end of the side guard in the longitudinal direction is arranged so that it is fixed against the bed post adjacent to the end. They are connected by a locking mechanism that includes an axially movable locking shaft, a locking hole that receives the locking shaft, and a spring that biases the locking shaft in the direction of fitting the locking shaft into the locking hole.

Furthermore, in order to enable removal of the side guard from the bed post, a pivot shaft included in one of the pivot mechanisms is provided so as to be movable in its axial direction, so that the pivot shaft can be removed from the bearing hole. is made possible.

Effects of the invention According to this invention, firstly, the side guard is attached to the bed for its original purpose;
, with the side guard rotated downward, the third
The following three states, i.e., a state in which the side guard is removed from the bed, can be realized using a simple pivot mechanism and a locking mechanism.

Further, in order to make the side guard rotatable, the only operation given to the locking mechanism is to move the locking shaft against the elasticity of the spring. Further, since the locking mechanism that holds the side guard in an upright state uses a spring to bias the locking shaft in the direction of fitting the locking shaft into the locking hole, a reliable locking state can be obtained.

You can also remove the side guard from the bed,
When reattaching the bed to the bed, it is only necessary to move one of the pivot shafts in the axial direction, so such an operation is easy.

In addition, the side guards can be completely removed from the bed, so if a bed according to this invention is available at a hospital, etc., one type of bed can be used for both those with side guards and those without. These two can be used for both purposes, and if necessary,
The ratio of different beds can be easily changed.

Embodiment The main parts of a bed in which an embodiment of this invention is adopted are shown in a perspective view in FIG. As shown in this drawing, the side guard 1 is arranged along the longitudinal side 3 of the bed 2, which is indicated by a chain line.

End plates 6 and 7 are fixed to the lower ends of both longitudinal ends of the side guard 1, respectively. One end plate 6 is fixed to one end of a lower pipe 8 constituting a part of the side guard 1, and a bearing hole 9 is provided in the downwardly projecting portion. The other end plate 7 is bent into an L-shape as a whole, and is fixed to the other end of the lower pipe 8 by welding or the like, as shown in FIGS. 6 and 7. Furthermore, one end of an inverted U-shaped upper pipe 10 that constitutes a part of the side guard 1 is fixed to the horizontally facing surface of the end plate 7 by welding or the like. A bearing hole 11 is provided in the downwardly projecting portion of the end plate 7.

As shown in FIGS. 1 to 3, the bed post 4 is provided with a pivot shaft 12 oriented in the horizontal direction. The pivot shaft 12 is fixed to the bed post 4 by welding or the like via a mounting bracket 13 bent into a U-shape, for example. The pivot shaft 12 is fitted into the bearing hole 9 provided in the end plate 6 described above, and a radius is formed at the tip thereof to facilitate the above-mentioned insertion.

As shown in FIGS. 1, 2, 4, 6 and 7, the other bed post 5 has
A pivot shaft 14 is provided so as to be movable in its axial direction. A mounting bracket 15 made of a combination of a rounded U-shaped pivot and an angular U-shaped plate is fixed to the side surface of the bed post 5 by welding or the like. This fitting 15 forms a cylindrical portion 15a that receives the pivot shaft 14. The pivot shaft 14 is
When received in the cylindrical portion 15a, it is movable in the axial direction thereof.

A branch rod 16 that projects laterally is formed on the pivot shaft 14 . Further, the cylindrical portion 15a includes a branch rod 1.
An L-shaped guide hole 17 is formed through the hole 6 .

The pivot shaft 14 fits into the bearing hole 11 provided in the end plate 7 described above. In order to facilitate this fitting, a radius is formed at the tip of the pivot shaft 14.

As best shown in FIG. 5 and also shown in FIGS. 1, 2, and 4, an L-shaped angle 18 is fixed to the side surface of the bed post 5 by welding or the like. A locking shaft 20 having an operating knob 19 is provided so as to be movable in its axial direction. More specifically, the locking shaft 20 is connected to the angle 18
While being inserted into the through hole 21 provided in the guide sleeve 22, the guide sleeve 22 surrounds the guide sleeve 22 and holds the guide sleeve movably in the axial direction. The guide sleeve 22 is fixed to the angle 18, for example by rivets 23. A spring stopper 24 is provided on the locking shaft 20, and this spring stopper 2
4 and a step formed at one end of the guide sleeve 22, a compression spring 25 is disposed so that the locking shaft 20 is always moved to the left in FIG. energized.

On the other hand, a locking shaft 20 is provided in a vertically extending portion of the upper pipe 10 constituting a part of the side guard 1.
A locking hole 26 is provided for receiving the. In addition, in order to facilitate fitting of the locking shaft 20 into the locking hole 26,
A radius is formed at the tip of the locking shaft 20.

The state shown in FIGS. 1 to 5 is a state in which the side guard 1 stands up along the bed posts 4 and 5 so as to perform its original function. This state is maintained because the respective pivot shafts 12 and 14 are received in the corresponding bearing holes 9 and 11, and the locking shaft 20 is fitted into the locking hole 26.

In order to rotate the side guard 1 outward and downward from the bed 2 from the above-mentioned state, use the operation knob 19.
The locking shaft 20 may be pulled out from the locking hole 26 through the locking hole 26. As a result, the side guard 1 becomes rotatable around the pivot shafts 12 and 14 that are aligned on substantially the same axis, and the side guard 1 can be rotated outward and downward from the bed 2. can. In order to return to the original attachment state again, the side guard 1 may be lifted up, and when the locking hole 26 is aligned with the locking shaft 20, the locking shaft 20 may be inserted into the locking hole 26. In addition, when performing the above-mentioned operation, simply lift the side guard 1 and push it slightly forcefully along the bed post 5, and the
It can be seen that the locking shaft 20 can fit into the locking hole 26. That is, as shown in FIG. 5, when the outer peripheral surface of the upper pipe 10 approaches the locking shaft 20, it guides the locking shaft 20 as shown by the imaginary line, and the locking shaft 20 moves into the locking hole 26. When aligned, the above-mentioned fitting can be automatically achieved by the action of the compression spring 25.

When you want to remove the side guard 1 from the bed 2, for example, grasp the branching rod 6 that was oriented downward as shown by the imaginary line in FIG. hole 1
7 along the side facing in the horizontal direction. As a result, the pivot shaft 14 moves to the right in FIG. 6 and escapes from the bearing hole 11. In this manner, when one pivot shaft 14 escapes from the bearing hole 11, the other pivot shaft 12 can be easily pulled out from the bearing hole 9. Note that the state in which the locking shaft 20 is fitted into the locking hole 26 is similar to that of the pivot shaft 14 described above.
It can be released either before or after the movement operation.

Conversely, in order to attach the removed side guard 1 to the bed 2, first insert one pivot shaft 12 into the bearing hole 9, and then insert the other pivot shaft 14 into the bearing hole 11. In order to operate the branching rod 16 so as to cause this to occur, and to stop this state, the branching rod 16 may be positioned at the end of the vertically extending side of the guide hole 17. Then, as described above, when the locking shaft 20 is fitted into the locking hole 26, reinstallation of the side guard 1 is completed.
