Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a spring bed, and more particularly to a spring bed in which a leaf spring of a spring head is formed of bamboo aggregate.

[0002]

[Prior art]

 In recent years, naturalization of living environment has been called out, and wood spring beds have attracted attention as beds with warm structures. This wood spring bed is a bed having an extremely simple structure in which a bed element configured by connecting a plurality of leaf springs on a rail as a frame material is provided, and is characterized by being particularly excellent in storage.

[0003] The leaf spring itself must function as a spring, and is formed by bending in an arch shape. When a human body is placed on the bed surface constituted by the leaf spring, the leaf spring is elastically deformed downward according to the load, and a cushion indispensable to the bed is generated. When the human body leaves the bed, the elastically deformed leaf spring returns to its original curved shape due to the restoring force.

[0004]

[Problems to be solved by the invention]

 By the way, a leaf spring for a wood spring bed has conventionally been manufactured using a so-called laminate material in which thin plates are laminated. Due to the diversification of materials, the use of materials other than wood is being studied, and leaf springs are also changing from uniform to rich. As the width, thickness, and stiffness (spring constant, etc.) of leaf springs change in search of more desirable wood spring beds, leaf springs also need to change to new structures. The ease of attachment and detachment of this connection structure in a wood spring bed takes precedence over other requirements.

[0005] In order to cut down and manufacture trees, the wood spring bed has caused a phenomenon of natural destruction of cutting down trees growing in mountain forests with an increase in demand. In addition, even if trees are planted, they require a 20- to 30-year cycle to grow and cannot keep up with demand.

An object of the present invention is to provide a spring bed in which the characteristics of a wood spring bed are improved and the function of the bed is improved without using a complicated groove structure.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the invention of claim 1 comprises two rails which are arranged in parallel at a constant distance, and the two rails are formed so as to form an upwardly curved bed surface on the rails. A plurality of leaf springs provided between the rails, a pair of connecting members at both ends of each of the plurality of leaf springs and connecting the leaf springs, and a connection between the connecting member and the rail. A spring head comprising a plurality of planar fastener elements that are separably connected to the leaf spring and the rail, wherein the leaf spring cuts a bamboo material along a fiber strip. And a plurality of unidirectional aggregated members formed in a plurality of layers, and a plurality of unity members arranged side by side along the fiber strip and combined are arranged on the front and back surfaces. Single-sided materials with different directions that intersect each other Characterized in that it is composed of a suit look.

According to the first aspect, since the leaf spring of the spring bed is formed of a bamboo aggregate, it is rich in elasticity, has warmth, and fuses naturally. In addition, since the bamboo aggregate is composed of two types, that is, the same-direction aggregate and the different-direction aggregate, and the two are combined, the elasticity can be increased or decreased to form a bed that matches the body shape.

[0009]

[Embodiment of the invention]

 Embodiments of the present invention will be described in detail with reference to the drawings.

As shown in FIG. 1, the spring bed according to the present embodiment has two rails 1 and 2 which are arranged in parallel at a predetermined interval, and curves above both rails 1 and 2. And a plurality of leaf springs 3 and 4 provided between the rails 1 and 2 to connect the leaf springs 3 and 4 at both ends thereof. And a pair of connecting members 5 and 6 to be combined.

As shown in FIG. 2, this spring bed is provided with a planar fastener element, for example, velvet tapes 7, 8 interposed between the connecting member 5 that connects the leaf springs 3, 4 and the rail 1. . One velvet tape 7 is fixed to the connecting member 5 side, and the other velvet tape 8 is fixed to the upper surface of the rail 1. Although not shown, the spring bed also has a similar planar fastener element between the connecting member 6 and the rail 2.

The rails 1 and 2 as support elements are formed by shaving a raw wood such as a hard oak, for example, into a desired shape. The rails 1 and 2 must be extended in length during use, but can be folded in two to reduce the length when stored. That is, as shown in FIG. 3, each of the rails 1 and 2 is formed by joining rail pieces 9a and 9b having a short length with a joint 10 and folding the rail at a joint 10 to determine a predetermined rail length. It is possible to make the length of half.

As shown in FIGS. 4 and 5, the leaf springs 3 and 4 according to the present embodiment are formed of a bamboo aggregate obtained by cutting bamboo into a fixed width and joining them by a bonding means such as an adhesive. ing. Bamboo wood has stronger fiber strips than wood and is inherently rich in elasticity. It is much more elastic than wood. The size of the leaf springs 3 and 4 is preferably 60 to 70 mm in width and 8 to 10 mm in thickness.

As shown in FIG. 4, the leaf spring 3 has a plurality of single pieces 3a obtained by cutting a bamboo material at a constant width in a fiber strip direction, and integrally connects them by a connecting means such as a binder. It is formed by laminating a plurality of sheets in the same direction, for example, two or three sheets. The fiber direction of bamboo is along the curved surface that is curved in an arch shape. The leaf springs 3 are rich in elasticity since the bamboo fiber strips are arranged in the same direction, and have a relatively large deflection when a load is applied. In other words, it is configured to be more flexible and changeable. The leaf spring 3 made of a bamboo composite material in the same direction is formed into an arch shape and is curved so that the curved surface faces upward and forms a bed surface on which the bedding rests in use. Is done. The leaf spring 3 constituting the bed surface is used in a standard area other than the specific area described later.

As shown in FIG. 5, a plurality of leaf springs 4 are arranged side by side along a fiber strip, and are combined with the same binder to form a single body 4a. And the inner layer is formed by laminating different direction aggregates (for example, 5 sheets) in which the fiber strips of the simple substance 4a cross each other. This leaf spring is relatively tough and has relatively little deflection when loaded. In other words, the structure is somewhat rigid because the layers where the fiber strips intersect are interposed. The leaf spring 4 made of the bamboo aggregate is curved in an arch shape along the direction of the fiber strip of the front and back single body 4a. It is formed so as to be curved in an arch shape, and the curved surface faces upward, and is arranged so as to form a bed surface on which the bedding rests in use.

As shown in FIG. 6, the leaf springs 4 are arranged in two specific areas S on the bed surface. The specific area S refers to an area in which cushioning properties are reduced with respect to the standard area N having an average cushioning property. In the specific area S, the amount of elastic deformation during use and when a load is applied is relatively smaller than that in the standard area N, and has an appropriate hardness.

The connecting members 5 and 6 for connecting the leaf springs 3 and 4 are attached to the ends of the leaf springs 3 and 4 respectively. The connecting member 5 is configured using an elastic material such as hard rubber. As shown in FIG. 4, the connecting member 5 includes a plurality of retainers 11 for holding the leaf springs 3 and 4. The retainers 11 are connected at equal intervals, and when the leaf springs 3 and 4 are inserted and held therein, the leaf springs 3 and 4 are regularly aligned.

At the time of storage, the leaf springs 3 and 4 are aligned and fixed by using a suitable means such as a stapler so that the leaf springs 3 and 4 do not come out of the holder 11 for winding while being wound. Is also good. Although not shown, the connecting member 6 is configured similarly to the connecting member 5.

It should be noted that the above-mentioned magic tapes 7 are provided four by four at regular intervals along the connecting members 5, 6 connecting the leaf springs 3, 4. The same number of magic tapes 8 are provided on the rails 1 and 2. These magic tapes 7 and 8 are fixed at predetermined positions by an adhesive.

The present embodiment has the above configuration, and in use, the two folded rails 1 and 2 are stretched and arranged in parallel at an interval corresponding to the bed width. Prior to this, the wound leaf springs 3 and 4 are expanded to remove any habit attached to the connecting members 5 and 6 during storage. The leaf springs 3 and 4 connected on the two rails 1 and 2 arranged in parallel are mounted, and the velvet tapes 7 on the leaf springs 3 and 4 are combined with the velvet tapes 8 on the rails 1 and 2 to be combined. 7. Stop each other. Thereafter, bedding such as a futon is used on the curved bed surface of the leaf springs 3 and 4 for use.

On the other hand, when disassembling the bed for storage, the magic tapes 7 and 8 are separated at each location, and the leaf springs 3 and 4 connected to the rails 1 and 2 are disassembled. Rails 1 and 2 are each folded at 10 joints, folded in two, and reduced in length. The leaf springs 3, 4 are wound with the leaf springs at one end while the connecting members 5, 6 are attached, and are wound up while rotating. At this time, the rails 1 and 2 may be rotated while being wound around the two folded rails 1 and 2. The wound leaf springs 3 and 4 are turned so that they do not return to the original position, for example, while being held down by a band while being held in place, fastened by a suitable fastener. Thus, it can be made into a bulky shape suitable for storage.

When leaf springs having various variations are used, the connecting members connecting the leaf springs also have a large thickness in order to match the thick leaf springs, for example, according to a change in the thickness of the aggregated material. Become. In this case, with the groove structure, the depth of engraving on the rail becomes deeper, so that the difficulty in attaching and detaching the leaf spring and the rail increases. In addition, when the thickness of the connecting member itself increases, the rigidity thereof is correspondingly increased, and it becomes difficult to wind up the leaf spring with the connecting member attached for storage.

In the present embodiment, the connection is not based on the groove structure, but based on connection using planar fastener elements such as magic tapes 7 and 8, and the connection and detachment can be performed irrespective of the change in the dimensions of the connection member. It is possible. In other words, it is possible to assemble simply by bringing the surfaces into close contact with each other, or it is possible to easily separate the surfaces simply by separating one surface from the mating surface.

Further, the connecting members 5 and 6 do not need to be slid along the groove, and the thickness of the connecting members 5 and 6 is sufficient to be sufficient for the retainer 11. Can be rolled up.

Further, in the spring bed according to the present embodiment, the leaf spring is selectively used between the specific area S and the standard area N depending on whether it is hard or soft. The specific area S coincides with the head and lower back of the human body (see FIG. 3). This makes it possible to improve the stability of the human body while maintaining the desired cushioning properties as a whole.

The arrangement of the specific area S may be replaced by the arrangement shown in FIG. 6, and the same specific area S may be additionally arranged at a position on the opposite side of the head. With this arrangement, the head of the human body can be placed on either side when using the wood spring bed.

[0027]

[Effect of the invention]

 In the present invention, since the leaf spring of the spring bed is formed of a bamboo aggregate, the spring is rich in elasticity, warmth and natural fusion.

Further, since the leaf spring is formed of a bamboo aggregate and is composed of two types of aggregates, one in the same direction and the other in the different direction, the elasticity of the bed can be increased or decreased since both are combined. , To form a bed according to the figure.

Further, since the connecting portion is formed by the planar fastener element between the connecting member connecting the leaf spring and the rail, the leaf spring and the rail can be easily connected at the time of assembly. Also, when disassembled, it is possible to separate the connected leaf spring from the other rail very easily.
