Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a bed installed in a relatively small room, and in particular, it is movable between when in use and when not in use, and makes effective use of floor space when not in use. This invention relates to an electric two-stage elevating bed that can be stored in the ceiling so that it can be used for various purposes.

[Prior Art] Today, with the diversification of lifestyles, more and more rooms are equipped with beds. In particular, in urban areas, the cost of housing continues to rise as part of the cost of living, and at the same time, the number of people living alone is increasing.
Recently, demand for so-called "one-room apartments" has been rapidly increasing. However, if the bed is fixed in such a small-scale room, the floor space it occupies cannot be used effectively, and it is virtually impossible to install a bed in a small room.

Conventionally, one end of the bed was fixed and the other end was raised up so that it could be stored on a wall, but this one does. When in use, it was troublesome to move the furniture or restore the space after standing it up, and there was also the inconvenience of tying mats and futons to prevent them from falling off when storing them, or storing them separately.

In addition, an elevating bed has been proposed in which the bed can be raised and lowered horizontally and stored in a space in the ceiling, but the early versions were manually operated, which placed a heavy burden on housewives and others in their daily tasks. Even if electrically operated devices appeared, the drive devices were still limited to saving labor and were no more than mechanisms, and there were no safety devices for moving large furniture; However, many of them were not refined enough to be used as furniture.

For this reason, the present applicant first proposed an electrically operated elevating bed (Utility Application No. 61-93889, name of the invention ``Electric Elevating Bed,'' etc.), and has progressed with its practical application by equipping it with various safety devices. .

[Problems to be solved by the invention] However, in the current residential environment, there is a demand for multiple beds at almost the same time due to conditions such as proximity to work and residence. There is no example of a bed with multiple levels of upper and lower beds, and an obstacle to such development is firstly the problem of elucidating the lifting and lowering operation in the mutual relationship between the two beds, and in particular, the use of a two-tiered bed frame for single lifting and lowering. It is necessary to ensure the safety of all persons.

[Means for Solving the Problems] The present invention was created in view of the above-mentioned circumstances with the aim of providing an elevating bed that can eliminate these drawbacks.
The first purpose is to manage the lifting and lowering operations when the bed frame is installed in multiple levels above and below in order to improve the accommodation capacity relative to the living room area. In an electrically-operated elevating bed in which the bed frame is raised and lowered by winding and unwinding the cables driven by an electric drive device, a partition wall is provided in the elevating groove of the guide rail, and multiple hoistways are arranged in parallel. A second object of the invention is to provide an electric lifting bed which is formed in rows and is characterized in that each hoistway is equipped with a bed frame having a built-in drive device that can be raised and lowered freely. To ensure the safety of each hoistway when each bed frame is operated independently in the lifting and lowering operation of bed frames equipped in multiple stages.

[Embodiment] The structure of the elevating bed of the present invention will be explained in detail based on a preferred embodiment shown in the drawings. First of all, Figure 1,
Referring to FIG. 2, the basic structure of the electrically operated elevating bed of the present invention will be explained. In the figure, reference number 1
indicates the entire elevating bed, 2 is the floor of the living room where this elevating bed 1 is installed, 3 is the ceiling, 4 is a wall that typically represents the structure of the building, and 5 is the main structure of the elevating bed 1 It is the body. The structure 5 consists of four columns 6 having a horizontal cross section suitable for a guide rail, and a stay 7 that connects the tops of the columns 6.
The lower member of the pillar 6 and the stay 7 can be adjusted in accordance with the height and internal dimensions of the room in which it is installed.

Reference numeral 10 denotes a bed frame which constitutes the other main body of the elevating bed 1, and the bed frame 10 is equipped to be able to rise and fall using pillars 6 as guide rails, and has a frame 11 at the bottom thereof, which is fixed to the frame 11. A side plate 12 that stands up around the periphery, an arm member 13 that protrudes from the frame 11 and engages the bed frame 10 with the groove 6a of the pillar 6.
It is made up of. The arm member 13 includes a hollow member that extends the frame 11 in the longitudinal direction, faces into the groove 6a formed on the opposing surface of the column 6, and engages in accordance with the interval, and this hollow member. It consists of a sheave for lifting and lowering, which will be described later, built into the tip of the sheave.

As shown in the upper part of the figure, a handrail 14 is provided on the upper surface of the side plate 12 of the bed frame 10, a flooring material 15 is stretched on the upper surface side of the hollow part formed by the frame 11, and a floor material 15 is provided on the lower surface side. A material 16 is stretched.

The frame 11 is constructed of a surrounding frame and internal beams made of a suitable metal material, and constitutes the main body of the bed frame 10.

Next, a drive device 20 for raising and lowering the elevating bed 10, generally indicated by 20, is incorporated inside the frame 11, and this drive device 20 includes an electric motor 21,
A support shaft 22, a plurality of winding drums 2 fixed to the support shaft 22
3. It consists of an endless chain 24 etc. that transmits driving force from the electric motor 21 to the support shaft 22. Each winding drum 23
One end of a wire rope 30 serving as a driving rope is wound around the wire rope 30, and the other end is connected to a plurality of sheaves 31 pivotally supported within the frame 11 and a hollow portion of the arm member 13 protruding toward the pillar 6 side. After passing through the groove 6a and being wound around the sheave 32 pivotally supported at the tip of the arm member 13 and changing direction, it passes through the groove 6a and reaches the upper end thereof, where it is fixed. 33 is a cord for supplying power to the electric motor 21, in preparation for raising and lowering the bed frame 10;
I am using curl code.

Therefore, the wire rope 30 is wound around the winding drum 23 and unwound by the forward and reverse rotation of the electric motor 21, thereby raising and lowering the bed frame 10. 40 in the diagram
is a coiled bullet wound around the outer periphery of the support shaft 22, and this bullet 40 has one end 41 fixed to the support shaft 22 and the other end 42 fixed to the frame 11. By this, the winding trunk 23 is connected to the wire rope 3.
When the bullet 40 rotates in the direction of feeding out the bed frame 10, the ammunition 40 twists and stores energy as the bed frame 10 descends, winds up the wire rope 30, and moves the bed frame 10.
When raising the bed, the electric motor 21 is energized to reduce its load, giving the lifting bed 1 of the present invention a distinctive advantage.

The wire rope 30 is equipped within the frame 11 with a device as a safety device that detects loss of tension or breakage due to the operation of the engaging member urged by the bullet.

Now, in the present invention, as shown in Figs. 1 and 2, two bed frames 10, an upper and lower bed frame, are installed horizontally as the elevating bed 1, spanning between pillars 6. In operation, both bed frames 10 are individually raised and lowered by a drive device 20 built into the frame 11.

That is, FIG. 3 is a detailed view of the pillars 6 forming the structure 5 of the elevating bed 1 of the present invention, and FIG. 3A is a horizontal sectional view, and FIG. 3B is a vertical sectional view.

As shown in Fig. a, the dual guide rail 60 of the present invention is fixed between and parallel to both side walls 6b of the groove-shaped structural member 6a. This guide rail 60 has a horizontal section with flanges 61 on both sides.
The arm members 13 of both bed frames 10 are respectively engaged in two parallel grooves 64 formed by the side walls 62 and the central partition wall 63. Therefore, there are differences in the widths of the upper and lower bed frames 10, and the larger lower bed frame 10 is usually placed in the groove on the outer side of the parallel groove 64, and the smaller upper bed frame 10 is placed in the inner side of the parallel groove 64. The user selects the size of the top and bottom. Of course, it can also be replaced during use.

The guide rail 60 extends the side wall 62 from the base end side to the column 6 side to form a fixing flange 65 that is fixed to the side wall 6b of the column 6, and at the same time forms a decorative edge. .

A plurality of holes 67 are bored in the center of the bottom wall 66 of the guide rail 60, and serve as holes for engaging the stoppers 50 for regulating the lower limit of the descent of each bed frame 10.

As shown in Figure b, the stopper 50 has a U-shaped vertical cross section with an upper side 51 and a lower side 52.
An upwardly directed hook portion 53 is formed on the tip side of the notch on the upper side 51, and can be freely engaged and detached from the attachment hole 67, and at this time, the tip of the lower side 52 comes into contact with the inner surface of the bottom wall 66. . 54 is a screw screwed into the upper side 51, and its head 55 is attached to the arm member 1.
When serving as a receiving seat for the lower surface of No. 3, the height of the upper surface can be finely adjusted.

A conventional limit switch is used to limit the upper limit of the rise of each bed frame 10. At this time, by forming a sensor on the handrail 14 of the upper bed frame 10, it is possible to further control safety.

Next, FIG. 4 shows another example of the structure of the guide rail 60. In the example shown in figure a, the installation to the column 6 is carried out inside the groove 64 for raising and lowering, and the bottom wall 66
An outwardly protruding ridge 68 is formed on the surface, reducing the overall expected thickness.

In the example shown in Fig. b, a plurality of guide rails 60 are formed for the upper and lower bed frames 10, and the structure of the pillar 6 and the guide rails 60 are formed into a unit. The members are simplified by placing them in parallel.

FIG. 5 shows another embodiment of the stopper. The stopper 70 in this example has a guide rail 6 as shown in a front view a, a side view b, and a plan view in FIG. 4b.
The fixing position is slidable relative to the guide rail 60, and includes a plate-shaped main body 71 that engages with the flange 61 of the guide rail 60 from the front, and a main body that is located within the groove 64 and has a U-shaped horizontal cross section. A backing part 72 facing the main body part 71 and a backing part 7 whose base end is fixed to the main body part 71
2 and a screw 73 that is screwed into the screw 73. The main body part 71 includes upper and lower flanges 74 whose width can be inserted into the groove 64, a receiving seat 75 formed thereon, a side flange 76, and a locking protrusion 7 provided on one of the left and right sides of the upper and lower flanges 74.
7, and a handle 78 is fixed to the outer surface. 80 is a stopper support, which has slits 81 arranged in multiple stages.
The above-mentioned engaging protrusion 77 is engaged to horizontally position the bed frame 10. a is the dimension between its lower end and the floor surface.

This stopper 70 is easy to attach and detach, and is attached to the front surface of the guide rail 60 across the groove 64.
When the screw 73 is tightened through the handle 78,
The flange 61 of the guide rail 60 is held between the main body part 71 and the tip of the backing part 72, and a stopper 70 of the bed frame 10 is formed on the guide rail 60 at an arbitrary position. Reference numeral 82 in the figure represents a cushion material that prevents the screw 73 from slipping when tightened.

However, in the present invention, the two bed frames 10 move up and down along double rows of guide rails 60, and since both hoistways are parallel at the top, the stopper for the upper bed frame 10 is The installation of the bed frame 10 must not interfere with the raising and lowering of the bed frame 10 below. In Figure a, only one of the guide rails 60 shown in Figure 4B is shown.

In addition, in FIG. 3a, the side wall 6b of the column 6
By lengthening the decorative edge 65 and the bottom wall 66, by providing a partition wall in the center, and by providing a counterweight in this space, in addition to the effect of the bomb 40, or Instead, the load of driving both bed frames 10 can be reduced.

In the configuration of the present invention, the upper bed frame 10
If a touch sensor is installed on the bottom surface, it can be used as a safety device to prevent unexpected accidents between the lower bed frame 10 as it rises, regardless of the individual lifting and lowering operations of both bed frames 10. can.

[Operation] As is clear from the above-described configuration of the present invention, the elevating bed 1 can be raised and lowered by a push button switch (not shown). As shown in FIG. 2, when using the elevating bed 1 which is raised and accommodated in the ceiling 3, the lower bed frame 10 is first lowered by pressing the lowering button. The lower bed frame 10 stops at the position of the lower stopper 50 (or 70, hereinafter the same) provided on its dedicated guide rail 60, and is ready for use here. When it is necessary to use a second bed, the upper bed frame 10 is lowered and stopped at the upper stopper 50,
Get into the state shown in Figure 2, and use the appropriate ladder to
It becomes possible to use tiered beds.

When it is necessary to make effective use of the indoor space, press the push button for raising the upper bed frame 10 in the reverse order, and the upper bed frame 10 will rise until it reaches the lower surface of the ceiling 3 and the upper limit switch will be turned on. When the bed frame 10 is activated and stopped, and then the lower bed frame 10 is raised, it stops at the lower surface of the preceding bed frame 10.

Even if the stopper of the present invention is of the locking type and is installed in the groove 64 of the guide rail 60, it uses the locking hole 67, so the stopper of the present invention cannot be used for lifting and lowering the bed except at the adjusted locking position. There is no obstacle to the lifting and lowering of the arm member 13 of 10, and in the case of a sliding type, even if it is installed in front of the groove 64 of the guide rail 60, it will not protrude toward the other guide rail side. There is no problem in raising and lowering the other bed frame.

The combination of the arm members 13 of the upper and lower bed frames 10 and the parallel grooves 64 of the guide rails 60 can be appropriately selected as described above.

[Effect of the invention] The elevating bed of the present invention has a bed frame that can be moved up and down along guide rails provided in the structure, and is raised and lowered by winding and unwinding of the rope driven by an electric drive device. In this type of electric lift bed, a partition wall is provided in the lift groove of the guide rail to form multiple parallel rows of hoistways, and each hoistway is equipped with a bed frame with a built-in drive device that can be raised and lowered freely. Therefore, firstly, it is possible to provide an efficient elevating bed that can increase the number of people accommodated by equipping a elevating bed based on the conventional technology with a plurality of bed frames to effectively utilize indoor space. It is possible to meet current demands. In addition, by forming guide rails in multiple rows, not only can the installed bed frames be formed with the same width, but also large and small bed frames can be formed, allowing the user to select and replace the upper and lower beds. It has a degree of freedom and can produce new effects that have never been planned before.

In addition, each bed frame is equipped with a specially formed guide rail so that each bed frame can be raised and lowered, and by arranging corresponding stoppers according to the raising and lowering of each bed frame, multiple beds that can be operated individually are installed. A tiered bed can be completed.
Furthermore, the structure of the guide rail does not require any special technology and is easy to manufacture. Furthermore, it has been proposed to employ various stoppers to regulate the lower limit of each bed frame.

In addition, the elevating bed of the present invention can be equipped with various safety devices, and since the basic structure is the guide rail, it has the advantage that there is no interference between them. In order to ensure safety from being accidentally pinched, a safety device consisting of a touch sensor can be installed on the underside of the upper bed frame as a safety device necessary for forming a multi-tiered bed. Therefore, it is possible to provide an electric elevating bed that is suitable for the modern living environment and style for both users and producers, and it has a special effect with a large contribution.
