Description

[Detailed description of the device]

[0001]

[Industrial applications]

  The present invention relates to a lift indicator in a bed lift mechanism.

[0002]

[Prior art]

  Recently, in beds, especially patient beds, the entire bed and floor boards are lifted and lowered. It is becoming popular that the function is adjustable. Among them, the entire bed is lifted The existing lifting mechanism was devised for the convenience of the patient or from the viewpoint of treatment. It has many advantages.

[0003]

[Problems to be solved by the device]

  On the other hand, the bed is complicated and it is a way to check the position of the bed. Steps will also be needed. For example, the above-mentioned lifting mechanism that can lift the entire bed How high is the entire floor, along with the bed's main frame? It is very difficult to see visually if it is adjusted. For that, the floor Since the height of the whole part does not fit, for example, from the bed to a wheelchair or a transfer bed. When transferring to a terminal, there may be a problem, and it takes time to readjust each time, which is important. There is a concern that it may delay the quick preparation and response of medical treatment.   The present invention has been made to solve such a problem, and the entire floor of the bed is Lifting indicator in the lifting mechanism of the bed that can freely adjust and support the height of the bed The purpose is to provide.

[0004]

[Means for Solving the Problems]

  In order to solve the above-mentioned problems, the present invention provides a caster holding member for a bed and a base portion. The outer tube is fixed, and the expansion and contraction tube, which is the support of the bed, is lifted inside the outer tube of the base. It is configured so that it can be moved back and forth, and an elevation indicator is attached to the outer tube of the base. Includes a tape measure indicating means rotatably incorporated in the housing, and the tip of the tape measure indicating means is Along with attaching to the expansion tube, a window for viewing the tape measure indicating means is formed on the housing. It is characterized by that.   Further, a visual recognition lens for magnifying and seeing through the tape-shaped support means is provided on the visual recognition window. It is characterized by that.

[0005]

[Action]

  Adjusting the height of the entire bed floor by operating the elevating mechanism allows the base outer tube to expand and contract. The tube moves back and forth. Due to the forward and backward movement of the expandable tube, the tip of the tape measure indicating means is moved. It is pulled out, and the scale display at that time can be confirmed from the viewing window. This As you can see, the height adjustment can be easily done while observing the display of the tape measure indicator from the viewing window. Since it is possible to check and adjust the position of the bed, It is possible to reduce the labor required by the person.

[0006]

【Example】

  Next, one implementation of the lifting indicator in the lifting mechanism of the bed according to the present invention By way of example, the following description is made with reference to the accompanying drawings.   In FIG. 1, reference numeral 1 is a lifting table of a bed lifting mechanism according to the present invention. 1 shows a bed to which an indicator (described later) is attached. This bed 1 is a bed (not shown) A mechanism that can change the overall position (for example, a lifting mechanism for the entire bed 1, The undulating mechanism for undulating the floor portion 2 of the bed 1) is provided.

[0007]   That is, the bed 1 includes the caster holding member 3 having the pair of casters 2 attached thereto. A vertically fixed base outer tube 4 and a lifting mechanism 5 for the base outer tube 4. It is provided with a telescopic tube 6 as a support leg of the bed 1 which is telescopic. Scarecrow Lifting indicators 7 are attached to the side surfaces of the base outer tube 4 respectively.

[0008]   The elevating mechanism 5 has a base inside an expandable tube 6 that slides out of the inner wall surface of the base outer tube 4. An internal leg pipe 8 fixed to the external pipe 4 and a screw screw provided in the internal leg pipe 8. Shaft 9, screw 10 for being screwed into this screw shaft 9, and said screw shaft 9 A driven gear 11 and a drive gear 12 of a helical gear, which is a rotary power transmission mechanism, at the tip. A power transmission shaft 13, which is a rotation axis of the drive gear 12, and a power transmission shaft 13 Via a transmission mechanism (not shown) It is qualitatively constructed.

[0009] In the elevating / lowering display 7, a tape measure-shaped indicating means 16 is rotatably built in the housing 15. The tip end of the tape measure indicating means 16 is inserted through the square hole 17 provided in the base outer tube 4. And is attached to the expandable tube 6 and is attached to the housing 15 with a tape measure indicating means 16 The visual recognition window 18 is formed. A scale is attached to the tape measure indicating means 16. The elastic tube 6 is constantly urged toward the winding side by a spring member (not shown), etc. When the tape is retracted to the base outer tube 4, the tape measure indicating means 16 is automatically wound. ing. The scale attached to the tape measure indicating means 16 is magnified in the visual recognition window 18. A visible viewing lens 19 is attached. It should be noted that the casing 15 is a base outer tube 4 It is adapted to be attached by a locking piece 21 to the locking hole 20 provided in the.

[0010]   Since the lift indicator 7 in the bed lifting mechanism is configured as described above, By operating the crank handle 14, the drive gear 12 of the helical gear, Rotational force is transmitted to the screw shaft 9 via the dynamic gear 11, and the screw shaft 9 is fixed. It moves up and down via the female screw 10 on the fixed side, whereby the telescopic tube 6 is moved to the base outer tube 4 And the pipe 8 in the leg are slidably moved, and the entire floor of the bed is moved up and down.   At this time, the tip end of the tape measure indicating means 16 is pulled out by the forward / backward movement of the expansion / contraction tube 6. The scale display at that time can be confirmed through the visual recognition window 18. Therefore, The height adjustment is performed through the visual recognition lens 19 from the visual recognition window 18 through the finger of the tape measure indicating means 16. The bed position can be confirmed easily because it can be done easily while looking at the scales shown. There is no need to make adjustments, and as a result, preparations for performing essential medical treatment are also made. It can be done promptly, and it will be possible to reduce the labor required for caregivers, etc. .

[0011]

[Effect of device]

  As described above, according to the present invention, the bed position can be visually and easily confirmed. Since it is possible to adjust the bed position, it is not necessary to adjust the bed position. The treatment can be performed without delay, and as a result, the caregiver's effort is reduced. It is possible to reduce.
