Description

[Detailed Description of the Invention] The present invention relates to a storage bed (bed), and particularly to a storage structure thereof.

Storage beds have already been provided that can be changed from a horizontal usage state on the indoor floor to a storage state in which they stand vertically against a wall in the room.

This type of bed can be used horizontally with either the headboard or footboard end touching the wall in the room, and then the end touching the wall can be raised upward along the wall surface. The other end is slid on the floor, and the entire horizontal bed is raised vertically and stored.

In order to make the bed have this undulation, one end of the link member or stay is pivotally attached to the center of the back of the bed, and the other end of the stay is pivotably attached to the wall of the floor.

The bed is raised and stored by pivoting this stay from a horizontal state to a vertical state, but during this storage,
In order to reduce the burden of manual operation, a strong extension spring connects the upper part of the pivot point on the floor and the middle part of the stay.

In order to achieve the above configuration, a large metal fitting having considerable strength is used which serves as both the pivot point on the floor of the stay and the anchor point on the floor of the spring.

A considerable number of screws are used to attach this metal fitting to the floor and wall above the floor.

As a result, the floor and walls will be damaged by numerous screw holes, and when the bed position is changed indoors, there will be a problem in that many screw holes will leave scars on the floor and walls. Attach the pair of side plates to the floor and wall with screws adjacent to both sides of the bed when the bed is stored as described above, and attach the side plates to the floor and wall with screws. A device was devised in which an L-shaped metal fitting was attached with a screw, this metal fitting was also screwed to the floor, the left and right metal fittings were connected by a horizontal bar, and the end of the aforementioned spring was hung on this bar. ing.

This item has smaller metal fittings on each side, and the two long side plates that extend from the floor to near the ceiling make the moment arm longer.
The number of screws required for attaching the wall and floor to the wall and the floor can be significantly reduced, and damage to the floor and wall caused by the screw holes can be reduced.

However, the problem of twisting of the metal fittings on both sides occurs as described below.

That is, the reaction force applied via the stay and the anchor reaction force of the extension spring are applied to this metal fitting in a coupled state.

This couple causes the metal fittings to be twisted and distorted, resulting in damage to and loosening of the screws that are attached to the floor and side panels.

The purpose of the present invention is to provide a storage bed that can avoid the above-mentioned drawbacks, and in order to achieve this purpose, the hinge portion that pivotally connects the end of the stay to both metal fittings is extended, and the above-mentioned It is fixed to the horizontal bar by welding or other means.

The present invention will be explained below with reference to the figures.

In FIG. 1, the storage bed 10 is moved from a horizontal use state shown by a solid line to a storage state shown vertically in a chain line, close to the wall 11 of the room, and vice versa, from a storage state to a use state. obtain.

As an intermediate stage of this change, a state shown in the same figure with a slanted chain line passes through.

The floor surface of No. 12 room is shown.

Next, the detailed structure of the bed 10 will be explained.

In FIG. 1, 13 is a pinerest, and 14 is a frame.

A folding leg 16 is pivotally mounted on the lower surface of the frame 14 close to the right footboard 15 with a pin 17.

However, this pivot mounting allows the folding legs 16 to pivot clockwise within a range of 90 degrees from the illustrated upright position.

A pair of fixed legs 19 are protruded from both left and right sides of the lower surface of the frame 14 on the left side of the bed 10 and the bed board 18 side.

Reference numerals 20 shown at the lower right side of FIG. 1 are casters, and one caster is mounted on each of the left and right sides, separated from each other.

Note that the folding leg 16 is the fixed leg 19 when viewed from the right side of the figure.
Similarly, it has a U-shape, and the frame 14 is connected to the two free ends of both legs.
is pivoted as described above.

The stay 21 has a U-shape as shown in FIG. 2, and the free legs are pivoted to the left and right metal fittings 22.

Reference numeral 23 designates a hinge portion for this pivot, which is fixed on the horizontal plate 22a of the metal fitting 22.

Each metal fitting 22 has a vertical plate 22b bent in an L-shape with respect to a horizontal plate 22a, and is fixed to the floor surface 12 and the side plate 24 (FIG. 1) through respective screw holes 25, as will be described later.

As shown on the right side of FIG. 2, the stay 21 has hinge portions 26 spaced apart on both left and right sides.

With this hinge 26, the stay 21 is pivotally attached near the center of the lower surface of the frame 14, as shown in FIG.

As shown in FIG. 2, both metal fittings 22 are connected by a bar 27 so as to face each other symmetrically.

A pair of anchor fittings 29 for the springs 28 are also fixed to the bar 27 at a distance.

Each spring 28 has one end hung on this anchor fitting,
The other end is the intermediate portion 21a of the stay 21 shown in FIG.
Can be hung on.

Since each spring 28 is attached under an extension load, as will be described later, when storing the bed 10, the load applied to the operator's hand due to the weight of the bed 10 is reduced, and the stored state is stabilized. let

As shown in FIG. 3, the left and right metal fittings 22 are fixed to the lower portions of the opposing inner surfaces of both side plates 24 using screw holes 25, respectively.

The side plates 24 are connected at the upper part by a shelf board 30, and the side plates 24, the shelf board 30, and the lower bar 27 constitute a rectangular framework as shown in FIG.

In this square frame, the upper shelf board 30 is fixed to the studs 32 of the inner layer of the wall surface 11 using two square metal fittings 31, and the lower horizontal plate 22a of both metal fittings 22 is fixed to the floor using screw holes 25. Screw onto surface 12.

This allows the framework to be fixed indoors.

Next, the usage status and storage operation will be explained below.

The state shown by the solid line in FIG. 1 is the state of use, in which the left Heradboard 18 is oriented toward the head.

To store the bed 10, first fold the folding leg 16 on the lower right side of the figure to the left side of the figure.

By this lying down, the casters 20 come into contact with the floor surface 12, and the bed 10 is slightly tilted to the right.

Next, place your operating hand on a location on the frame 14 near the headboard 18, lift this location, increase the above-mentioned inclination of the bed 10, and continue lifting.
An inclined intermediate stage is reached, indicated by the dashed line in the figure.

If the same operation is continued, it will finally reach the vertically erect storage state shown by the chain line in the same figure.

During this retraction operation, the two springs 28 apply a rotational moment to the stay 21 that causes the stay 21 to rotate about the hinge portion 23 at its leg base.

This rotational moment allows the bed 10 to reduce resistance due to its weight when transitioning from a horizontal position of use to a vertical storage position.

Next, the features of this proposal will be explained below.

This plan consists of both side panels 24, upper shelf board 30, and lower bar 2.
7. The metal fittings 22 on both sides constitute a rectangular frame, and the ends of the stays 21 and springs 28 of the bed 10 are pivotally attached or locked to this frame, so that the ends of the stays 21 and springs 28 of the bed 10 are pivoted or locked. This allows for installation with fewer screw holes and less damage, and even if the bed installation position is changed due to a change in the interior design, unsightly screw hole marks remaining on walls and floors can be minimized.

Since the horizontal par 27 and each hinge part 23 are in an integrally fixed relationship, the horizontal par 27, each metal fitting 22, and the hinge part 23 form a rectangular box-shaped metal fitting at both left and right ends of the horizontal par 27.

Therefore, even if the anchor reaction force applied from the spring 28 to the anchor fitting 29 of the spring 28 and the reaction force applied from the stay 21 to the hinge part 23 act as a couple, due to the rectangular box-like structure described above, The metal fittings 22 will not be twisted or distorted.

Therefore, it is possible to prevent the screws from loosening and damaging the indoor floor surface 12 and the side panels 24.

The bed according to the present invention can also provide the following effects.

That is, the side plates 24 also serve as a cover for accommodating the bed 10 when stored, and the shelf boards 30 also serve as a cover and a shelf for placing items for normal indoor use.

If the wall surface 11 does not have studs as shown in Figure 3, it is also possible to attach the hooks 31 to the inner inner surfaces of the side panels 24 to match the position of the stiffeners in the wall. It is.
