Description

[Detailed explanation of the idea]

[0001]

[Field of Industrial Application] The present invention relates to a lift indicator in a bed lift mechanism.

[0002]

BACKGROUND OF THE INVENTION Recently, beds, especially beds for patients, that have functions that allow the entire bed and floorboard to be raised and lowered and adjusted in elevation are becoming popular. Among these, an elevating mechanism that allows the entire bed to be raised and lowered was devised from the viewpoint of patient convenience or treatment, and has many advantages.

【0003】

[Problems to be solved by the invention] On the other hand, beds have become more complex, and a means to confirm the position of the bed has become necessary. for example,
Regarding the above-mentioned elevating mechanism that allows the entire bed to be raised and lowered, it is very difficult to determine to what height the bed's main frame and the entire floor are adjusted by visual estimation. For this reason, the height of the entire floor does not match, which may cause problems when transferring from the bed to a wheelchair or transfer bed, and it takes time to readjust the bed each time, making it difficult to quickly perform important treatment procedures. There are concerns that this may cause delays in preparations. The present invention was made in order to solve such problems, and its purpose is to provide a lift indicator for a bed lift mechanism that can freely adjust and support the entire floor of the bed to a desired height. do.

[0004]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a base outer tube that is fixed to the caster holding member of the bed, and a telescopic tube that is a support of the bed inside the base outer tube. It is configured to be movable forward and backward by an elevating mechanism, and an elevating indicator is attached to the outer tube of the base, and this elevating indicator has a tape measure-shaped indicating means rotatably built into the casing, and the tip of the tape measure-shaped indicating means is attached to the outer tube of the base. The device is characterized in that it is attached to the telescopic tube and a window for viewing the tape measure-shaped indicating means is formed in the casing. Further, the present invention is characterized in that the viewing window is provided with a viewing lens for magnifying and seeing through the tape measure-shaped support means.

[0005]

[Operation] When the height of the entire bed floor is adjusted by operating the elevating mechanism, the telescopic tube moves forward and backward from the base outer tube. By moving the telescopic tube back and forth, the tip of the tape measure-shaped indicating means is pulled out, and the scale display at that time can be confirmed through the viewing window. In this way, the height can be easily adjusted by looking at the display on the tape measure-shaped indicator through the viewing window, so there is no need to take time to check and adjust the bed position, and the effort that would otherwise be borne by caregivers, etc. It becomes possible to reduce the

[0006]

[Embodiment] Next, an embodiment of a lift indicator in a bed lift mechanism according to the present invention will be described below with reference to the accompanying drawings. In FIG. 1, reference numeral 1 indicates a bed to which a lift indicator (described later) in a bed lift mechanism according to the present invention is attached. This bed 1 is equipped with a mechanism (not shown) that can change the position of the entire bed (for example, a lifting mechanism for the entire bed 1, a raising and lowering mechanism for raising and lowering the floor 2 of the bed 1, etc.).

[0007] That is, this bed 1 includes a base outer tube 4 that is fixed vertically to a caster holding member 3 to which a pair of casters 2 are attached, and these base outer tubes 4.
The bed 1 is further provided with a telescopic tube 6 as a supporting leg of the bed 1, which is extendable and retractable by an elevating mechanism 5.
A lift indicator 7 is attached to each side of the base outer tube 4.

[0008] The elevating mechanism 5 moves the base outer tube 4 within the telescopic tube 6 that slides on and exits the inner wall surface of the base outer tube 4.
The intra-leg pipe 8 fixed to and this intra-leg pipe 8
a screw shaft 9 provided therein, a female screw 10 screwed into the screw shaft 9, a driven gear 11 and a drive gear 12 of a helical gear serving as a rotational force transmission mechanism at the tip of the screw shaft 9; It is substantially composed of a power transmission shaft 13 that is a rotation axis of the drive gear 12, and a crank handle 14 that applies rotational force to the power transmission shaft 13 via a transmission mechanism (not shown).

[0009] In the lift indicator 7, the housing 15
has a tape measure-shaped indicating means 16 rotatably built in,
The tip of the tape measure-shaped indicating means 16 is attached to the telescopic tube 6 through a square hole 17 provided in the base outer tube 4, and a window 18 for viewing the tape measure-shaped indicating means 16 is formed in the housing 15. has been done. The measuring tape-shaped indicating means 16 is provided with a scale, and is always biased toward the winding side by a spring member (not shown), etc., and when the telescopic tube 6 is retracted to the base outer tube 4, the measuring tape is The state indicating means 16 is adapted to be automatically wound up. A viewing lens 19 is attached to the viewing window 18, which can magnify and see through the scale marked on the tape measure-shaped indicating means 16. The housing 15 is attached to a locking hole 20 provided in the base outer tube 4 by a locking piece 21.

[0010] Since the elevation indicator 7 in the bed elevation mechanism is configured as described above, by operating the crank handle 14, the screw The rotational force is transmitted to the shaft 9, and the screw shaft 9
is moved up and down via the female thread 10 on the fixed side, whereby the telescopic tube 6 slides between the base outer tube 4 and the inner leg pipe 8, and the entire floor of the bed is raised and lowered. That will happen. At this time, as the telescopic tube 6 moves forward and backward, the tip of the tape measure-shaped indicating means 16 is pulled out, and the scale display at that time can be confirmed through the viewing window 18. Therefore, the height can be easily adjusted while viewing the scale indicated by the tape measure-shaped indicating means 16 through the viewing window 18 and the viewing lens 19, so that there is no need to take time to check and adjust the position of the bed. As a result, preparations for performing important medical treatments can be made quickly, and the burden on caregivers and the like can be reduced.

[0011]

[Effect of the invention] As mentioned above, according to the invention,
Since the position of the bed can be visually and easily confirmed, there is no need to take time to adjust the bed position, and important treatment procedures can be performed without delay.As a result, caregivers, etc. It becomes possible to reduce labor.
