Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a slatboard support structure for a bed, and more particularly to a slatboard support structure that is particularly preferable when applied to a simple bed such as a bunk bed.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a bed slat support structure in which a plurality of slats are mounted on a step provided on the inner surface of a frame of a bed and the outer periphery of the slats is held by the frame. For example, as disclosed in Japanese Utility Model Laid-Open No. 60-86164, when two divided slats are mounted on a frame composed of a front and rear frame and a side frame, an edge plate is attached to the inner surface of the side frame. In addition to forming a step portion for supporting and supporting the slats, a crosspiece member is laid across the frame body so as to cross or cross the joints of the respective slats. A structure has been proposed in which the joints of the slats are mounted to reduce downward deflection.
[0003]
The bunk bed described in the above publication is assumed to be used by an adult or a child with a large physique, and may be configured to have a sturdy structure as a whole. Can be reliably controlled. However, providing the crosspiece member increases the weight and inevitably increases the cost.
[0004]
On the other hand, in the bunk bed used mainly by children, if the structure using the above-mentioned crosspiece member is adopted, the weight becomes heavy and inconvenient to handle, and the cost per step is significantly increased as a whole. Cost increases. In addition, the crosspiece member provided on the upper bed becomes an obstacle that narrows the upper space in the lower bed, and also has a disadvantage that it directly enters the eyes when sleeping on its back, resulting in a feeling of pressure. Furthermore, although the downward deflection of the snowboard can be restricted by the crosspiece member, the upward jumping cannot be prevented.
[0005]
[Problems to be solved by the invention]
In the conventional support structure of the slats, the strength of the joints of the slats is weak because the slats are separated. When the slats are attached to the frame, the strength is increased. The present invention has been reached based on the idea of increasing.
[0006]
That is, in view of the above-described situation, the present invention intends to solve the problem of bending and jumping the joints of a plurality of slats installed in the frame of a bed in a simple bed such as a bunk bed. The present invention is to provide a bed support structure for a bed that can be simultaneously regulated by a simple structure in which the respective snowboards are substantially connected when mounted on the bed.
[0007]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the present invention provides a bed support structure for a bed, in which a plurality of slats are mounted on a step provided on the inner surface of a bed frame, and the periphery of the slats is held by the frame. In order to regulate the vertical displacement of the slats at the joints of the respective slats, a single projecting piece projecting from the lower surface to the lower surface of the other slat at a position closer to one side than the center line of one slat. The bed support structure for the bed, which is provided in a plurality and set so that the protruding pieces of both the saw blades are close to each other, is configured.
[0008]
Here, it is preferable that the two pieces of the same shape of the slats are provided, and the projecting pieces projecting at the joints of the slats are provided at positions where they do not overlap when rotated 180 degrees.
[0009]
Further, a long reinforcing member arranged in a direction perpendicular to the joint is provided on the lower surface at a position nearer to the center line of each of the slats, and the protruding piece is formed by extending the reinforcing member. Is a more preferred embodiment.
[0010]
In this case, it is free to adopt a structure in which the protrusions and recesses are fitted to the side surfaces of the adjacent protrusions, or a structure in which the protrusions and the bottom surface of the snowboard are engaged.
[0011]

【The invention's effect】
The bed support structure for the bed of the invention according to claim 1 as described above is configured such that a plurality of snowboards are supported on the step provided on the inner surface of the frame body of the bed, and the outer periphery of the snowboard is held by the frame body. The bed has a slatboard support structure, and protrudes from the lower surface to the lower surface of the other slat in a position close to one side of the center line of the slats so as to restrict the vertical displacement of the slats at the joints of the slats. In addition to providing one or a plurality of protruding pieces and setting so that the protruding pieces of both slats are close to each other, it is possible to reliably regulate bending and jumping at the joints of the slats. With a structure in which only one or a plurality of projecting pieces projecting from the lower surface of one of the slats to the lower surface of the other slat is provided, it is possible to reliably regulate the bending and jumping at the joint of the slats. Further, since the projecting piece is formed at a position closer to the center line of the slatted joint, it is possible to effectively regulate the bending and jumping of the center part of the slatted joint. Since it is set so that the projecting pieces of the slats come close to each other, the movement in the direction in which both projecting pieces come into contact can be restricted.
[0030]
According to the second aspect, since two identical slats can be used, an increase in manufacturing cost can be minimized.
[0031]
According to the third aspect of the present invention, since a slightly longer reinforcing member is used and only a part of the reinforcing member protrudes from the joint, it can be configured extremely simply and inexpensively.
