Description

[Detailed Description of the Invention] This invention relates to an elevating bed device that can effectively utilize a narrow space.

Beds occupy a large amount of space even when not in use, so they tend to be avoided in small living spaces. On the other hand, there are beds that can be folded along the wall, but even when folded, they are quite bulky and are not sufficient in terms of space utilization.

This device is an elevating bed device that allows the bed to be raised to the interior of the ceiling when not in use, supports the bed at a predetermined height from the floor when in use, and forcibly prevents the bed from falling. The purpose is to provide

This invention will be explained below based on the illustrated embodiments. In FIGS. 1 to 3, reference numerals 1 and 1' denote a pair of left and right supports, which are composed of square pipes, and at least their upper ends are connected to each other by a horizontal bar 2.
Usually fixed to the wall. Slide metal fittings 3, 3 are externally fitted onto both pillars 1, 1', and via these slide metal fittings 3, 3, an elevating bed 4 which becomes a bed frame is cantilevered and can freely slide up and down. ’ is supported. The slide fitting 3 has a rectangular cylindrical shape and is integrally connected to the elevating bed 4. In order to smoothly slide the slide fitting 3, rollers 5 and 6 are mounted on shafts at the lower front and upper rear sides of the fitting 3, as shown in Fig. 4. It is worn.

A fixed pulley 7 is attached to the lower surface of the center of the horizontal beam 2, and a corresponding movable pulley 8 is attached to the center of the side edge of the elevating bed 4 closer to the columns 1, 1'.
A wire 9 wound around both pulleys 7 and 8 is guided from the fixed pulley 7 to one of the pillars 1, and guided to the lower part through the inside of the pillar 1. A drum box 10 is fixed to the lower part of one of the pillars 1, and a winding drum 11 for the wire 9 is mounted therein. The internal structure of the drum box 10 is as shown in FIG. 5, and a ratchet wheel 12 and a brake wheel 13 are coaxially fixed to the winding drum 11.

14 engages with the ratchet wheel 12 and rotates the winding drum 1.
This is a latch pawl that prevents the rotation of the ratchet 1 from being reversed, and is elastically biased by a spring 15 in the direction of engagement with the ratchet wheel 12.
16 is a brake band wrapped around the brake wheel 13;
17 is a brake lever that pulls this brake band 16. A winding handle 19 is attached to the shaft 18 of the winding drum 11. 20,2
1 is a pulley that guides the wire 9.

22, 22' are suspension rods, and the lifting bed 4
and to forcibly stop the descent of the elevating bed 4 at a predetermined position from the floor, and forcibly preventing the elevating bed 4 from falling even if the mechanical brake does not brake due to some kind of failure. It is set as.

That is, the upper ends of the suspension rods 22, 22' are pivotally connected to the horizontal crosspiece 2, and the lower ends of the suspension rods 22, 22' are connected to the lifting bed 4 as shown in FIG. The guide rail 23 provided on the horizontal frame part of the pillar side,
It is movably engaged in the engagement elongated hole 23' and can be slid laterally.

24 is the side frame of the bed, 25 is a ladder, and 26 is a supporting leg.The ladder 25 and supporting leg 26 are pulled up to a height parallel to the elevating bed 4, and hooks 27, 28 are attached.
It can be locked and held in that position.

In the above configuration, when using the ladder 2, first lower the elevating bed 4 to the lower limit position, and then
5 and support legs 26 are pulled down. In this state, the latch pawl 14 engages with the ratchet wheel 12, which prevents the wire 9 from unwinding, and the suspension rods 22, 22' are completely lowered, so the lifting bed 4 cannot be lowered any further. do not. Further, the front side of the elevating bed 4 is supported by a chair 26 and support legs 26.

Next, when you don't need a bed, use the chair 25 and support legs 2.
6, and turn the winding handle 19 at the bottom of the column 1 in the winding direction. As a result, the wire 9 is wound around the drum 11, so that the entire elevating bed 4 is raised as shown in FIG.

When the elevating bed 4 is raised, the latch pawl 14 engages with the ratchet wheel 12 and prevents the winding drum 11 from being reversed, so that the elevating bed 4 does not fall unexpectedly.

Next, to lower this elevating bed 4 again,
The latch pawl 14 is removed from the ratchet wheel 12 while applying the brake to the drum 11 by operating the brake lever 17. Then, the wire 9 is gradually unwound and the elevating bed 4 is lowered by its own weight.

FIG. 6 shows an application example in which the elevating bed device of this invention is used as an elevating storage table. In this example, the support column 1 is extended above the ceiling plate 29,
To enable an elevating bed 4' (storage stand) to rise to a height flush with a ceiling board 29. 30 is an opening provided in the ceiling plate 29, and this is an opening provided in the ceiling plate 29, and this is an opening provided in the ceiling plate 29, and this
It almost matches the size of the (storage stand). In addition, it is desirable to provide a lock fitting 32 on the front edge of the elevating bed 4' (storage table), which can be released using a string 31. 33 is a receiving metal fitting on the ceiling plate 29 side. It goes without saying that this embodiment also includes the same slide fitting 3, pulleys 7, 8, drum box 10, etc. as in the examples shown in FIGS. 1 to 5.

As described above, with this invention, by raising the elevating bed, the large space under the elevating bed can be effectively utilized inside the ceiling.
By pulling the elevating bed up to the ceiling when it is not needed, the space where the elevating bed is located can be utilized without wasting it.

Furthermore, the elevating bed of the present invention is supported by a suspension rod and is forcibly prevented from descending at a predetermined height from the floor. There have never been any accidents caused by people sleeping on the bed, and there is no fear that people who sleep on the bed will be injured by the bed falling, and it is very effective from a safety standpoint. It is something that can be demonstrated.
