Description

  The present invention relates to a folding mechanism of a folding bed.

  Conventionally, various methods have been devised and implemented as means for reducing human power when folding a folding bed. For example, in Patent Registration No. 3015012, a structure is provided in which a spring means is provided between a pedestal and both frame bodies, and a structure that assists the human power of folding work by utilizing the elastic return force of the spring. These conventional devices have the same structure in the side view, the bed frame, the spring, and the pillar, and the spring mounting position is set near the leg side end and the floor of the folding column. ing.

  The problem of the present invention is that, for a thin folding slatted bed, the conventional folding method using the elastic return force of a spring cannot be used because of the thin structure. An object of the present invention is to provide a mechanism that reduces the manpower during folding and exhibits a smooth folding operation by utilizing an elastic restoring force such as a spring even in a thin structure.

  In a thin folding slatted bed where two slats of the same shape are connected horizontally and foldable, the slatted bed is folded in an inverted V-shape so that the backs of the swords are close to each other. The elastic material is placed inside the thickness of the slatted bed on the two locking brackets attached at the left and right asymmetrical positions across the linking part in the direction perpendicular to the connecting part that connects the slats on the bottom of Stretch. The stretched elastic material was in a contracted state when the slatted bed was folded.

The folding mechanism of the foldable bed, which is a conventional technique, cannot be used for a thin foldable bed because of its structure. The folding mechanism according to the present invention can be used for a thin folding bed or a non-thin folding bed. When used for a foldable bed that is not thin, the space under the bed can be used widely and effectively.
The position and quantity of the elastic member such as a coil spring can be changed according to the specification of the bed. When the coupling center part is lifted by holding the finger padding prevention member that also serves as a handle at the time of folding, when the coupling part moves to the upper position of the coil spring as shown in FIG. Human power when folding by acting as an auxiliary force is reduced, and a smooth folding operation can be performed by the synergistic effect of the rotating body attached to the side end.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a plan view of the embodiment of the present invention in a horizontally developed state, and FIG. 2 is a bottom view of the embodiment of the present invention in a horizontally deployed state. As shown in detail in FIG. 10, the two slats are connected by a connecting member and a connecting member fixing part so that they can be folded and horizontally expanded, and the front side of the connecting portion is a finger pad that also serves as a handle when folded. As shown in FIGS. 6, 7, 8, and 9, the prevention member is rotatably attached to the L-shaped component.
Two locking metal fittings are attached in the direction perpendicular to the saw joint connecting portion from the center position of the two saw connecting portions. The mounting position of the locking bracket is on the back side of the pass as shown in Fig. 2, one side is counted from the middle of the first and second pieces of the second piece counted from the connecting part, and the other is the fifth piece counted from the connecting part. And the middle of the sixth piece of the sushi. A coil spring is stretched over the locking metal fitting. At this time, the coil spring is pulled and stretched, and the contraction force of the coil spring pulls the two saws in the direction of the connecting portion and keeps the state of horizontal development. The contraction force of the coil spring acts as an auxiliary force when folding the folding slatted bed, and the folding operation can be performed with a small force.

FIG. 3 is a front view of the embodiment of the present invention in a horizontally developed state.
The contact surfaces of the two soots are formed perpendicular to the floor surface, the contact surfaces of the soot are in close contact with each other when horizontally deployed, and the bottom surface of the scissor bed has a flat structure without being bent at the connecting portion.
The coil spring is attached to the locking metal fitting via the S-shaped metal fitting inside the thickness of the slatted bed main body, and the coil spring at this time is in a stretched state. The structure of the slat contact surface, the contraction force of the coil spring, and the coil spring mounting position stabilize the two slats in a horizontally developed state.

  FIG. 4 is a front view illustrating a state in the middle of folding of the folding slatted bed according to the embodiment of the present invention. The folding operation can be performed more smoothly by the rotating body attached to the side end of the slat piece.

  FIG. 5 is a diagram for explaining a coil spring and a latch fitting attached to the folding slatted bed according to the embodiment of the present invention. The coil spring is stretched around the locking bracket by an S-shaped bracket.

  FIG. 6 is an enlarged perspective view illustrating the handle / fingering preventing member and the L-shaped part when folded, of the folding slatted bed according to the embodiment of the present invention. 7, 8 and 9 are enlarged cross-sectional views illustrating the relationship between the handle / fingering prevention member and the L-shaped part during folding. The handle / fingering prevention member at the time of folding is fixed by an L-shaped part and a wood screw B, and the two slats are connected to the oval hole G formed in the L-shaped part via a locking screw F. It is pivotally attached to four positions inside the leg.

  FIG. 10 is a partially enlarged view for explaining a connecting portion of the folding slatted bed according to the embodiment of the present invention. A belt-like connecting member is passed to both sides of the connecting portion on the back side of the slat connecting portion leg, and a connecting member fixing part is placed on the connecting member and fixed with a wood screw E. The slatted leg portion of the connecting member fixing portion is notched to the thickness of the connecting member and the connecting member fixing component, so that the connecting member fixing component does not protrude from the back surface of the slatted leg portion.

  FIG. 11 is a front view for explaining a folded state of the folding slatted bed according to the embodiment of the present invention. At this time, the coil spring stretched around the locking metal via the S-shaped metal is contracted.

  As described above, the folding slatted bed according to the embodiment of the present invention has a coil spring stretched on the back of the bed via an S-shaped bracket with a locking bracket, and is located within the thickness of the slatted bed main body. By attaching to the asymmetrical position straddling the connecting part in the direction perpendicular to the connecting part, the contraction force of the coil spring stabilizes the horizontal development surface in the use state of the bed at the time of horizontal deployment, and when the coil spring is folded, the coil spring The contraction force has the effect of significantly reducing human power. This attachment position structure of the coil spring can be applied to a conventional folding bed, and in that case, the space under the bed can be used widely and effectively.

  A plurality of coil springs according to the present invention may be attached in parallel.
