Abstract

(57) [Summary] [Purpose] To be able to store the head / footboard provided on the bed out of the way if necessary. [Structure] The head / foot board 3 is movable in the vertical direction, and an engaging member 6 is provided to selectively fix the upper position and the lower position of the head / foot board.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to beds, and more particularly to beds suitable for use by patients.

[0002]

[Prior Art]

 The bed typically includes a bed body and head / foot boards provided at both ends of the bed body in the longitudinal direction so as to respectively project upward. Note that the “headboard” and the “footboard” are only distinguished by which one comes to the head side or the foot side, and therefore, in this specification, as not being particularly distinguished, The term "head / footboard" is used.

When a bed is used by a patient as described above, the presence of the head / footboard can be an obstacle during examination or treatment, or when carrying the patient.

In order to prevent such a head / foot board from getting in the way, it is proposed in Japanese Utility Model Publication No. 55-40043 to rotate the head / foot board, if necessary, and to It is proposed in Japanese Utility Model Publication No. 57-56756 to remove the footboard.

[0005]

[Problems to be solved by the device]

 However, the former technique requires a space for rotating the head / foot board. For example, when the head / foot board is placed close to the wall surface, the wall surface becomes an obstacle, and the head / foot board is disturbed. Sometimes you can't rotate the board. Therefore, beds with such a mechanism must be placed in a relatively large room.

On the other hand, in the latter technique, it is troublesome to carry the removed head / foot board and place it in another place, and vice versa, to carry the head / foot board from another place to the bed and attach it. And there is a labor burden.

The object of this invention is therefore to try to provide a bed which can solve the problems as described above.

[0008]

[Means for Solving the Problems]

 This invention is directed to a bed, which is provided with a bed body and head / foot boards provided so as to project upward at both longitudinal ends of the bed body. In order to solve the problem, the head / foot board is provided so as to be movable in the vertical direction, and an engaging member for selectively fixing the upper position and the lower position of the head / foot board is provided. It is characterized by being prepared.

[0009]

[Action]

 In this invention, the head / footboard can realize a normal bed use condition when it is in the upper position, and a non-obtrusive condition such as a medical examination when it is in the lower position. it can.

[0010]

[Effect of the device]

 Thus, according to the present invention, since the head / footboard is moved in the vertical direction, it is not necessary to prepare a special space for moving the head / footboard. This is because under the head / footboard in normal use, a space is always formed as a result of lifting the bed floorboard from the floor surface to a predetermined height. Therefore, the bed according to the present invention can be used in a small room without any problem.

Further, since the head / foot board always operates in a state where it is incorporated in the bed, there is no need for labor and labor to remove and install the head / foot board.

【Example】

 FIG. 1 is a perspective view showing an entire bed 1 according to an embodiment of the present invention. FIG. 2 is a sectional view showing a main part of the bed 1 shown in FIG.

The bed 1 includes a bed body 2 and a head / foot board 3 provided at both ends of the bed body 2 in the longitudinal direction so as to project upward.

The head / foot board 3 is held by the legs 4 of the bed body 2 and is movable in the vertical direction. 1 and 2, the state in which the head / footboard 3 is in the upper position is shown by a solid line, and the state in which it is in the lower position is shown by a chain line. The leg 4 forms a space 5 for accommodating the head / foot board 3 therein.

Engagement members 6 are provided on the side portions of the leg portions 4, as well shown in FIG. The engaging member 6 includes an L-shaped lever 8 rotatably supported by a pin 7 located at a fixed point. A key 10 is rotatably connected to one end of the lever 8 via a pin 9. An operating rod 12 is rotatably connected to the other end of the lever 8 via a pin 11. A torsion spring 13 is arranged around the pin 7. The torsion spring 13 urges the lever 8 to rotate around the pin 7 in the clockwise direction in FIG.

The key 10 is inserted into a guide hole 15 provided in a vertical wall 14 arranged in the leg portion 4 and can be moved in a substantially horizontal direction. The end of the movement of the key 10 to the left according to FIG. 2 is defined by the step 16 provided on the key 10 abutting the vertical wall 14. On the other hand, the operating rod 12 is guided so as to move in a substantially vertical direction by a guide hole 18 provided in the upper surface wall 17 of the leg portion 4.

In such a configuration, the engagement member 6 maintains the state shown in FIG. 2 when no force is applied to the operation rod 12. That is, the operation rod 12 projects relatively upward from the top wall 17, and the key 10 projects relatively leftward (FIG. 2) from the vertical wall 14.

An upper engagement hole 19 and a lower engagement hole 20 are provided in the side surface of the head / footboard 3 facing the vertical wall 14 while vertically changing their positions. The upper engaging hole 19 and the lower engaging hole 20 receive the key 10 described above. In the state shown by the solid line in FIG. 2, the key 10 is received in the lower engaging hole 20. In the state shown by the alternate long and short dash line in FIG. 2, the key 10 is received in the upper engaging hole 19.

In this embodiment, fixing members 21 and 22 are provided on the leg 4 and the head / foot board 3, respectively, and a ridge 23 is stretched between the fixing members 21 and 22. This spring 23 acts to lift the head / footboard 3 against the gravity acting on the head / footboard 3. Therefore, when the head / foot board 3 is lifted, the burden is reduced.

The head / foot board 3 realizes a normal use state when it is in a state shown by a solid line in FIGS. 1 and 2. When the presence of the head / foot board 3 is an obstacle, the operation rod 12 is pushed downward. As a result, the key 10 is retracted via the lever 8 against the elasticity of the torsion spring 13. Therefore, the key 10 escapes from the lower engagement hole 10. As a result, the head / footboard 3 can be moved downward. Since the downward movement of the head / foot board 3 is performed against the elasticity of the spring 23, the head / foot board 3 does not drop suddenly. The head / foot board 3 is brought into a state in which it does not project from the leg portion 4 by applying a light force from above, and in this state, when the pushing force from the operating rod 12 is removed, the key 10 comes into contact with the upper engaging hole. Accepted on 19th. This fixes the position below the head / footboard 3.

On the contrary, when it is desired to move the head / foot board 3 upward, the operating rod 12 is also pushed in. As a result, at least the upper end portion of the head / footboard 3 is projected from the leg portion 4 by the action of the spring 23. Next, the head / foot board 3 is lifted by holding the protruding upper end portion, and when the head / foot board 3 reaches a predetermined upper position, the pushing force from the operating rod 12 is removed. As a result, the key 10 is received in the lower engagement hole 20, and the position of the head / foot board 3 above is fixed.

Although not shown, a member may be provided for defining the vertical movement range of the head / foot board 3.

Further, the engaging member 6 can be replaced with one having other structure.
