Abstract

PURPOSE:To raise and adjust a leg bottom to support a leg part of a user in a proper desired height from a frame surface. CONSTITUTION:Plural locking claws 6 are formed on a receiving frame 5 on an under surface opposed to a bed frame 2 of a leg bottom 3d, and on the bed frame 2, a stay 7 is selectively locked on the plural locking claws 6 on the receiving frame 5 by a torsion spring, and the leg bottom 3d is supported. An operation lever to raise and operate the leg bottom 3d together with the receiving frame 5 is arranged in an end part of the receiving frame 5. Thereby, operability is largely improved, and a leg raising mechanism capable of coping with user's liking and a sick and wound condition can be provided.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bed provided with an undulating mechanism for a floor, in which a leg bottom supporting a user's leg can be lifted and adjusted to a desired height from a frame surface. The present invention relates to a leg raising adjustment mechanism for a leg bottom.

[0002]

2. Description of the Related Art Conventionally, so-called Gatch beds with undulating back bottoms and leg bottoms have been widely adopted for beds, and in recent years, due to labor shortages of nurses and the like, electrification has progressed to save labor. I'm out. According to such a gatch bed, there is an advantage that the patient can operate the floor undulating mechanism by himself to take a desired posture. further,
Recently, in the above-mentioned gatch bed, in addition to the function of raising the leg by the raising and lowering mechanism, a type in which the leg bottom can be manually adjusted has been considered. According to the leg lifting mechanism, it is adjusted and supported so as to lift the joint between the knee bottom that supports the patient's thigh and the leg bottom, so that the tip end side of the leg bottom is supported in an inclined state downward toward the frame. This is because it is not possible to support the leg bottom in a substantially horizontal state, and it is necessary to raise the leg part depending on the preference of the user or the condition of injury or illness. This is to cope with such a case. In this case, while the stay for supporting the leg bottom is provided on the frame side, a plurality of adjusting locking claws for locking the stay tip is provided on the leg bottom side. With such a mechanism, the leg bottom can be lifted from the frame surface to a desired height, and the leg bottom can be held in a substantially horizontal state, and the above-mentioned demand can be addressed.

[0003]

However, in the above-mentioned mechanism, there is little clearance between the leg bottom and the bed frame, and the hand is inserted to lift the leg bottom.
The operation of locking the stay tip to the locking claw on the back surface of the leg bottom is not easy. The reason is that in order to bring the leg bottom to the desired position, the stay is selected and locked by the locking claws. Confirm which locking claw should be used to lock the stay. It is difficult to use and very difficult to use. The present invention has been proposed from such a background, in a bed provided with a floor undulating mechanism,
It is an object of the present invention to provide a leg-bottom adjusting mechanism for a leg bottom in a bed or the like in which a supporting position of a leg bottom supporting a user's leg can be freely adjusted.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a bed provided with a floor undulating mechanism, in which the floor is divided into a plurality of sections and each of the sections is bent and connected.
On the surface of the leg bottom that supports the user's leg, facing the bed frame, place a receiving frame that is oriented toward the long side of the bed frame and that has a plurality of locking claws lined up from the end of the leg bottom. A stay, which is provided on the bed frame side and has one end selectively locked to a plurality of locking claws in the receiving frame to adjust and support the leg bottom, is rotatably mounted. The frame is configured such that the one end is constantly urged so as to come into contact with a plurality of locking claws in the receiving frame, and an operating lever for lifting and operating the leg bottom together with the receiving frame is provided at the receiving frame end. Characterize.

[0005]

[Function] When the floor undulation mechanism is activated, normal back raising and leg raising adjustments can be performed. When the operation lever is operated from the leg-raised state to lift the leg bottom together with the receiving frame, the stay is constantly urged to come into contact with the locking claws of the receiving frame. Following the frame, the tip of the stay comes into contact with the locking claw of the receiving frame, and the stay tip is locked by the locking claw that corresponds to the lifting angle of the leg bottom. Can hold the bottom.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a leg raising and adjusting mechanism for a leg bottom in a bed or the like according to the present invention will be described below with reference to the accompanying drawings with reference to an embodiment. FIG. 1 shows a bed 1 provided with a floor undulating mechanism. The bed 1 includes a floor 3 arranged on a bed frame 2 on a back bottom 3a, a waist bottom 3b, a knee bottom 3c, and a leg bottom 3d. It is configured to be divided and connected so as to be bendable, and to raise the back and legs by a floor undulating mechanism (not shown).
As shown in FIG. 2, on the lower surface of the leg bottom 3d facing the bed frame 2, a pair of support frames 4 provided parallel to the longitudinal direction of the bed 1 and a receiving frame 5 are rotatable so as to overlap with each other. A plurality of locking claws 6 are formed on the receiving frame 5 from the end side of the leg bottom 3d, while one end of the plurality of locking claws 6 of the receiving frame 5 is formed on the bed frame 2. 3d
The stay 7 for undulating and supporting is mounted rotatably so that the stay 7 is always biased by the torsion spring 8 against the plurality of locking claws 6 in the receiving frame 5. An operating lever 9 for lifting and operating the leg bottom 3d together with the receiving frame 5 is provided at the end of the receiving frame 5.

The leg-up adjusting mechanism for the leg bottom 3d in the bed or the like according to the present invention is constructed as described above, and its operation will be described below. When the floor raising / lowering mechanism (not shown) is activated, the back bottom 3a is raised, and the connection between the knee bottom 3c and the leg bottom 3d can be lifted to adjust the leg raising. At this time, the distal end side of the leg bottom 3d is inclined obliquely downward toward the bed frame 2, and the distal end of the stay 7 is in contact with the locking claw 6 on the distal end side of the receiving frame 5. Here, when the operation lever 9 is operated to lift the leg from the raised state, the leg bottom 3d together with the receiving frame 5 is obtained.
Is rotationally displaced about the connection with the knee bottom 3c. Since the stay 7 is constantly urged by the plurality of locking claws 6 in the receiving frame 5 by the torsion spring 8, the stay 7 follows the receiving frame 5 of the leg bottom 3d and the tip of the stay 7 is positioned on the tip side of the leg bottom 3d. The tip of the stay 7 is locked to the locking claw 6 corresponding to the lifting angle of the leg bottom 3d while being in contact with the locking claw 6 of the receiving frame 5. The leg bottom 3d can be held at the position (see FIG. 3). As described above, in the leg raising adjustment mechanism for the leg bottom according to the present embodiment, it is not necessary to operate the stay 7 only by lifting the operation lever 9, and the holding position of the leg bottom 3d can be adjusted. Bed can be provided which can greatly improve the patient's needs and treatment conditions.

[0008]

As described above, according to the present invention, when the operating lever is operated to lift the leg bottom together with the receiving frame, the stay is constantly biased to the protruding side.
The operation of lifting the stay is unnecessary, and the tip of the stay follows the receiving frame at the bottom of the leg and abuts the locking claw of the receiving frame,
Even if you release your hand, you can hold the leg bottom in that position, the operability is greatly improved, the user's preference,
It is possible to provide a leg raising mechanism corresponding to an injured situation.
