Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a bed with a raised floor plate.

(Prior art) A bed with a raised floor plate rotates and raises the back floor plate to put the patient in a raised position, and in addition to the back floor plate, the lumbar and leg floor plates also rotate and raise the patient, etc. to make the patient sit up. Conventionally, the floor board to be raised and lowered, the floor board support frame, and the member for driving the floor board up and down were attached at the time of manufacturing, and the product was transported to the customer in this state. For this reason, the packaging size and weight increased, and it was often difficult to transport the product to users such as general households.

In order to solve this problem, for example, as disclosed in Japanese Utility Model Publication No. 55-47415, the floorboard, the floorboard support frame, and the lifting drive member for the floorboard are constructed separately during manufacturing and transportation. There is also a sectional bed with a floor plate that can be assembled at the customer's delivery location.In such a sectional bed with a floor plate that can be assembled at the customer's delivery location, as disclosed in the above-mentioned publication, the fulcrum of rotation of the back floor plate is supported. A hinge boss is provided protrudingly in the portion where the floor plate supports, and a hinge with an engagement groove is provided on the floor plate support frame, and the hinge boss is inserted into the engagement groove and engaged.
The back floor plate is attached to the floor plate support frame and is configured to be rotatable at the attachment site. After the back floorboard is attached to the floorboard support frame in this way, a telescopic rod or the like as a lifting member is connected to the floorboard support frame to assemble the backboard so that it can be moved up and down.

(Problem to be solved by the invention) Conventionally, the back floor plate has been attached to the floor plate support frame using the hinge and hinge boss that constitute the rotation fulcrum of the back floor plate. In this case, play is naturally necessary to enable rotation, and therefore, it is not possible to obtain a securely attached state, and there are problems such as occurrence of looseness and easy detachment. Furthermore, although the telescopic rod for lifting and lowering drives is an important part, it must be assembled by the customer himself or by a salesperson who is not an expert in assembly. Therefore, there is a problem that the reliability of assembly cannot be guaranteed due to mistakes such as attaching the telescopic rod in the opposite direction.

The present invention aims to solve the above-mentioned problems.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the floorboard type bed of the present invention has a first support member that is rotatable in correspondence with a rotational fulcrum at one end of the back floorboard. A tapered fitting portion is provided protrudingly on the first support member, a second support member is provided on the other end side of the back floor plate, and a gas spring is provided on the second support member. The operating side end of the gas spring is rotatably fixed, the other end of the gas spring is rotatably fixed to the first support member, and a fitting frame having an upwardly expanding shape is provided on the floor plate support frame. By fitting the fitting portion into the fitting frame, the back floorboard is supported on the floorboard support frame so as to be rotatable and up and down.

(Function) In the above configuration, the back floor plate and the floor plate support frame can be transported in a separated state. At this time, for the back floorboard, the gas springs are fixed at both ends to the first and second support members, respectively, as described above, and the first support member side is removed and fixed after being carried in. You can also. Then, at the delivery location, when the fitting part is fitted into the fitting frame,
The support member of the back floor plate is firmly supported by the floor plate support frame by so-called taper fitting, and this support member rotatably protrudes from the back floor plate.
The back floor plate can be rotatably supported with respect to the floor plate support frame using the rotating portion as a fulcrum. By operating and extending the gas spring fixed to the back floor plate in advance, the back floor plate can be rotated upward relative to the floor plate support frame. In addition, when the first support member side of the gas spring is removed during transportation, the above-mentioned usage state can be achieved by fixing only this part before supporting the back floor plate as described above.

(Example) Next, embodiments of the present invention will be described with reference to the drawings.

In the figure, reference numeral 1 denotes a back floor plate, and a first support member 3 is rotatably protruded in correspondence with a predetermined pivot point 2 at one end of the back floor plate 1. This first support member 3 is formed into a bar shape in the width direction of the back floor plate 1, and has a rotation support arm 17 that supports the rotation fulcrum 2.
It is protruded so that it can rotate freely. This first support member 3 includes a tapered fitting portion 4 and a support arm 18.
is installed protrudingly. Further, the back floor plate 1 is provided with a second support member 19 on the other end side. Reference numeral 7 is a gas spring, and this gas spring 7
The structure utilizes the compressibility of gas to expand or shorten, and the incompressibility of liquid to achieve a fixed state, and release of the fixed state is operated by an operating lever 8 provided at the operating end. It is said that Therefore, the gas spring 7 is attached to the second support member 19.
The operation side end is rotatably fixed, and the other side end is rotatably fixed to the first support member 3.

In the configuration shown in FIG. 2, the back floor plate 1 is constructed integrally with the lumbar floor plate 9 and the foot floor plate 10 by sequentially bendably connecting them, and the lumbar floor plate 9 is placed on the back floor plate 1.
The foot floor plate 10 is bent onto the lumbar floor plate 9 to be in a folded state.
As shown in FIG. 2a, the folded state can be changed to a planar folded state by removing the other end of the gas spring 7 from the first support member 3. In this case, it is only necessary to connect the other end of the gas spring 7 and the first support member 3 after delivery, and the connection is only made at one point, and there is no need to judge the connection direction of the gas spring 7. Therefore, the work is easy and there is little risk of incorrect assembly.

On the other hand, in the configuration shown in FIG. 3, the back floorboard 1 is constructed separately from the other floorboards 9 and 10, and is connected after the back floorboard 1 is supported by the floorboard support frame 5, as will be described later. Reference numeral 5 denotes a floor plate support frame, and the floor plate support frame 5 is provided with a fitting frame 6 that is flared upward.

In this configuration, when the fitting portion 4 of the back floor plate 1 is fitted into the fitting frame 6 of the floor plate support frame 5,
The first support member 3 is firmly attached to the floor plate support frame 5 by the so-called tapered fitting between the fitting part 4 and the fitting frame 6.
Supported by Therefore, the back floor plate 1 can be rotatably supported with respect to the floor plate support frame 5 using the rotating portion of the first support member 3 as the fulcrum 2.

In this state, if the operating lever 8 is operated to make the gas spring 7 expandable and retractable, the gas spring 7 will be biased and expanded by the pressure of the gas filled inside, and the patient, etc. The back floor plate 1 can be rotated and raised relative to the floor plate support frame 5 against the load of . After a predetermined rotational rise, when the operation of the operating lever 8 is stopped, the gas spring 7 becomes non-expandable and the back floor plate 1 is fixed at that position. Further, in this state, after operating the operating lever 8 to make the gas spring 7 expandable and retractable again, the back floor plate 1 can be lowered against the bias.

As mentioned above, the back floor plate 1 can be configured to be connected to the lower back floor plate 9 and the foot floor plate 10 in a flexible manner in order as shown in FIG. 2. In this case, the lower back floor plate 9 and the foot floor plate 10 are For example, by providing a moving member 11 such as a roller at the bending portion,
It can be configured to support the back floor plate 1 movably along the floor plate support frame 5 at the same time as the above-mentioned back floor plate 1 is rotated and raised and lowered. This configuration has the advantage that all of the floorboards can be attached and removed with one touch, as shown in Figure 2c, and that the entire floorboard can be packed into a very small size by folding it as shown in Figure 2a. There is.

On the other hand, the configuration shown in FIG. 3 is such that the back floor plate 1 and other floor plates are separated during transportation, that is, the support frame 12 that supports the lumbar floor plate 9 so as to be able to rise and fall is placed at a point a. The support frame 12 is fixed so as to be rotatable and movable left and right, and both sides of the support frame 12 are connected to support rods 13 and 13', respectively, and the floor plate is supported at the end of the foot floor plate 10, that is, at point b. It is rotatably fixed to the frame 5, and the support rods 13, 13' and the foot floor plate 10 are moved in conjunction with the raising and lowering of the back floor plate 1. In this configuration, the waist floor plate 9 and the foot floor plate 10 are connected to the floor plate support frame 5 at two points a and b.
Although there are connection points b to the back floor plate 1, the number of connection points b is small, and the connections are simple connections, so the work is easy. In addition, the floorboard support frame 5 is
Since the basic structure includes the footboard 14, the headboard 15, and the frame members 16, 16 corresponding to the longitudinal direction of the bed, these can also be assembled, thereby further increasing the ease of transportation.

(Effect of the invention) As described above, the present invention enables the back floor plate to be rotated up and down on the floor plate support frame by the simple operation of fitting the fitting part on the back floor plate side to the fitting frame on the floor plate support frame side. Since the back floor plate and the floor plate support frame can be transported separately, this has the effect that it can be easily transported even in narrow hallways and stairs when transported into general homes. . After fitting and supporting as described above, the fixed gas spring is operated by the operating lever to extend or shorten it, thereby allowing the back floorboard to rotate and rise relative to the floorboard support frame. There is an effect. In this way, the gas spring, which is an important part as a telescopic rod for lifting and lowering, is fixed in advance at least at its operating end, so it is less likely to cause inconveniences such as forgetting to bring it in or having the wrong model. There is no need for any assembly work at the delivery location, or the work is fixed at one location with little risk of making mistakes, so there is an effect that reliable assembly can be performed.
