Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bed having floor height display means for easily confirming the height of the floor and the like.

[0002]

[Prior Art]

 2. Description of the Related Art Recently, beds, especially beds for patients, have become widespread, which have the function of being able to adjust the elevation and undulation of the entire bed or floor plate. Among them, an elevating mechanism capable of elevating and lowering the entire bed is devised for the convenience of the patient or from the viewpoint of treatment, and has many advantages.

[0003]

[Problems to be solved by the device]

 On the other hand, the bed becomes complicated and it becomes necessary to check how the bed is positioned. For example, to describe the lifting mechanism that allows the entire bed to be lifted and lowered, it is very difficult to see visually how much the bed main frame and the entire floor are adjusted. For this reason, the height of the entire floor does not match, which may cause a problem when transferring from a bed to a wheelchair or a transfer bed, for example. There is concern that it may cause delays in quick preparation. The present invention has been made to solve such a problem, and provides a bed having a floor height display means capable of adjusting and supporting the bed at a desired height while checking the entire floor of the bed. With the goal.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a leg extension mechanism on each leg of the bed so that the floor and the entire main frame can be raised and lowered, and the leg extension mechanism includes: An interlocking shaft for transmitting power and an operation handle are detachably connected to the interlocking shaft, and an elevating indicator is installed near the connection point of the interlocking shaft with the operating handle. The measuring means is equipped with a tip end of the tape measure indicating means attached to the locking member attached to the interlocking shaft, and a visualizing window for visually recognizing the scale indicated by the tape measure indicating means is provided on the elevation display. It is characterized by being formed. Further, the elevation display is arranged in a gap between the side frame of the bed and the floor, and the viewing window is directed upward.

[0005]

[Action]

 When the operation handle is operated, power is transmitted to the leg extension mechanism via the interlocking shaft, and the legs extend and contract. At this time, since the locking member rotates together with the interlocking shaft, the tip of the tape measure indicating means is pulled out, and the height of the floor can be confirmed by the scale indication at that time. In addition, since the viewing window of the lift indicator is positioned upward in the gap between the side frame and the floor, it can be easily viewed while operating the operating handle. Therefore, it does not take time and effort to confirm and adjust the bed position, and it is possible to reduce the labor required for caregivers and the like.

【Example】

 Next, a bed having a floor height display means according to the present invention will be described below with reference to the accompanying drawings by way of one embodiment. As shown in FIG. 1, the floor portion elevating mechanism 1 is configured such that each leg portion 3 of the bed 2 is provided with a leg extending / contracting mechanism 4 so that the entire floor portion 5 and the like can be raised and lowered.

The leg portion 3 is formed by a caster holding member 7 having casters 6 attached thereto, and a base outer tube 8 fixed vertically to the caster holding member 7. The expansion and contraction pipe 9 is provided. Further, above the telescopic pipe 9, there is provided a gear storage portion 10 in which a gear mechanism that constitutes the leg extension / contraction mechanism 4 is incorporated, and a lateral leg pipe 11 is provided so as to penetrate the gear storage portion 10. ..

As shown in FIG. 2, the leg expansion / contraction mechanism 4 includes an internal leg pipe 12 fixed to the base outer pipe 8 in an expansion pipe 9 that slides out from the upper end of the base outer pipe 8. A screw shaft 13 provided in the in-leg pipe 12, a screw 14 that is screwed into the screw shaft 13, and a driven gear 15 and a drive of a helical gear, which is a gear mechanism, at the tip of the screw shaft 13. The gear 16 is substantially composed of a gear shaft 16, an interlocking shaft 17 that is a rotation shaft of the drive gear 16, and a detachable operation handle 18 that applies rotational power to the interlocking shaft 17.

In the leg side pipe 11, a lift indicator 19 is attached near the connection point of the interlocking shaft 17 with the operation handle 18, and a tape measure indicating means is provided in a housing 20 of the lift indicator 19. 21 is built in, and the tip end portion of the tape measure indicating means 21 is inserted into the inside through an introduction port 22 formed in the lateral leg pipe 11 (see FIGS. 3 and 4) and attached to the interlocking shaft 17. It is attached to the locking member 23. The casing 20 is formed with a visual recognition window 24 for visually observing the scale display of the tape measure indicating means 21 (see FIG. 5). In this case, the lift indicator 19 is attached so that the visual confirmation window 24 can be confirmed from the gap between the side frame 25 of the bed 2 and the floor portion 5 (see FIG. 6).

The locking member 23 is made of resin, has a square hole 26 formed therein so as to be fitted to the interlocking shaft 17, and has a notch 27 for holding the tip end of the tape measure indicating means 21. ..

Since the bed 2 having the floor height display means is configured as described above, when the operation handle 18 is operated, power is transmitted to the leg extension mechanism 4 via the interlocking shaft 17, The legs 3 expand and contract. That is, the turning force is transmitted to the screw shaft 13 via the drive gear 16 and the driven gear 15 of the helical gear in the leg expansion / contraction mechanism 4, and the screw shaft 13 moves up and down via the female screw 14 on the fixed side. As a result, the telescopic pipe 9 slides between the base outer pipe 8 and the leg inner pipe 12, and the entire floor of the bed moves up and down. At this time, since the locking member 23 rotates together with the interlocking shaft 17, the tip end of the tape measure indicating means 21 is pulled out, and the height of the floor 5 can be confirmed by the scale indication at that time. Since the viewing window 24 of the lift indicator 19 is positioned upward in the gap between the side frame 25 and the floor portion 5, it can be easily viewed while operating the operation handle 18. (See Figure 6). Therefore, it does not take time and effort to confirm and adjust the position of the bed 2, and as a result, preparations for performing essential treatment actions can be quickly performed, and the caregiver's labor can be reduced. Becomes

[0012]

[Effect of the device]

 As described above, according to the present invention, since the bed position can be visually and easily confirmed, it is not necessary to adjust the bed position and it is possible to perform important medical treatment actions without delay. As a result, it becomes possible to reduce the labor required for caregivers and the like.
