Description

  The present invention relates to a bed laying board that is used by spreading two cocoons on the floor and laying a futon on the cocoons, and more specifically, it is a foldable and ventilating made of two cocoons. The present invention relates to a high-performance bed laying board.

  Conventionally, in order to prevent stuffiness of a futon while sleeping, a cocoon child is laid under the mattress, and a space is provided between the floor surface and the mattress to improve air permeability and improve sleep.

And, a bed laying plate in which two cocoons are connected by a hinge is used by deploying the two cocoons around the hinge when used as a bed laying plate, and when the door is stored, the bed is laid around the hinge. It is possible to switch to a folded posture in which a piece of a kite is folded. In addition, the support is made by connecting the four rod-shaped members so as to form a rectangular shape so that the two folds can be rotated around the hinge so that the two folds can be maintained in a mountain-shaped inclined posture. One having a frame on one of the kites has already been proposed. This is because one rod-like member constituting the rectangular support frame is pivotally connected to the end opposite to the hinge side of one of the hooks connected by the hinge, The entire support frame is swingably provided. Then, the support frame in a state of swinging in a horizontal posture so that the lower end of the side hook to which the support frame is not attached, of the two scissors in the mountain-shaped inclined posture, is grounded to the floor surface. In this way, it is possible to prevent the two scissors from maintaining the tilted posture by preventing the scissors from swinging to the opening side at the same time as being placed and supported by contact with the support frame from the horizontal direction. In addition, one end of a pulling string for swinging and operating the support frame to the bottom surface of the hook element on the side to which the support frame is pivotally connected penetrates the support frame and connects the other end of the string. Pulling the string connected to the hinge at the upper end further upward, after passing through the hinge and connecting it, with one of the slanted ridges placed on the support frame floating upward Thus, by swinging the support frame upward, the support frame is positioned on the bottom surface of the scissors, so that the two scissors can be folded (see, for example, Patent Document 1). ).
JP 2003-33254 A

A bed laying board that has two cocoons connected by a hinge can be folded around the hinge, and can be stored between furniture or leaned against a wall. Since there is no means for maintaining the posture, the spider was unfolded during the storage operation, or it was unfolded from a state of leaning against a wall or the like.
In addition, the two kites in the slanted posture are structured so that the lower end of one kite child is received by the support frame, so that the kite kit floats up when something else hits the bed laying board. In some cases, the edge of the spider detaches from the support frame and the two spiders expand.
In addition, in order to change the posture of the two spiders maintained in the tilted posture to the folded posture, as described above, one of the spiders in the slanted posture is slightly lifted upward, and then the upper end side of the spider The string had to be pulled further upward, and the operation for changing the posture to the folded posture was very difficult.

  In view of such problems, the present invention can not only be changed to a mountain-shaped inclined posture or a folded posture when not used as a bed laying plate, but can also be used as a futon by placing a futon on the bed laying plate in an inclined posture. In addition, the operation for changing the posture from the inclined posture to the folded posture can be easily and quickly performed, and even when a person or an object hits the bedboard in the inclined posture, the inclined posture can be maintained. An object of the present invention is to provide a bedding board.

In order to solve the above-mentioned problem, the bed for a bed according to the present invention is composed of two pieces of a cocoon ridge having a substantially rectangular shape and the same size, a folding posture in which the two pieces of a cocoon fold are overlapped, and the two pieces. A connecting member for connecting the two cocoon blades so that the posture can be freely changed to a use posture in which the cocoon child is deployed almost horizontally, and the connecting member is positioned at the upper end so that the two cocoon children have a mountain shape. A string-like or belt-like attitude maintaining member that connects a predetermined position in the inclination direction of the one hook element and a predetermined position in the inclination direction of the other hook element to maintain each of the hook elements in an inclined posture, and one end A locking portion that can be locked and unlocked on a locked portion provided on the other hook element on the other end side of the posture maintaining member connected to the one hook element on the side, and A plurality of upper surface side plate members constituting the upper surface Characterized in that let comprising a plurality of vent holes penetrating in a vertical direction in at least one.
Therefore, the two scissors can be changed to a mountain-shaped inclined posture so that their connecting members are at the upper end, and the two intermediate scissors in the tilt direction can be connected to each other by the posture maintaining member. It is possible to maintain an inclined posture. Furthermore, since the locked portion provided in the spear child and the engaging portion provided in the posture maintaining member are locked at substantially the middle position in the inclination direction of the spider child, a person or an object collides with the spider child. Even if the spider is lifted up slightly, the locked state cannot be easily released. Further, since the upper surface side plate member is provided with a plurality of ventilation holes, when the futon is laid, it is possible to ventilate the contact portion between the futon and the upper surface side plate member through the ventilation holes.

  The vent hole may be configured so that a hole provided on the upper surface of the upper surface side plate member is larger than a hole provided on the lower surface of the upper surface side plate member.

  Further, in order to maintain the two folds of the folding posture in the posture, the folding portion can be locked and unlocked to the locked portion at a portion closer to the hook than the locking portion of the posture maintaining member. You may provide a latching | locking part.

  Further, the two cocoon ridges are maintained in an inclined posture in which the connecting member is located at the upper end and is in a mountain shape, or the two cocoon ridges are maintained in a folded posture in which the coupling member is located at the upper end and are overlapped and folded. Each of the lower ends may be provided with a moving rotator that can rotate in contact with the floor surface.

  The scissors have a plurality of the upper surface side plate members arranged in parallel with a predetermined interval in the front-rear direction orthogonal to the width direction in a posture along the width direction, and on the lower surface of these upper surface side plate members. A plurality of lower surface side plate members are attached at intervals greater than a predetermined interval between the upper surface side plate members in the lateral width direction, and the upper surface side plate portions located at the lowermost portions of the two scissors in the inclined posture The sliding cloth member may be wound around the position where the lower surface side plate member is removed in the longitudinal direction.

  Further, a plurality of short plate-like foot members that are in contact with the floor surface and support the hook element are attached to the lower surface of the lower plate member constituting the one hook element at predetermined intervals along the longitudinal direction. A foot member identical to the foot member may be attached to the lower surface of the lower surface side plate member constituting the foot member at a position where it contacts the foot member when the two eyelids are folded.

  In addition, the posture maintaining member is formed of a belt-like and flexible belt, and the locked portion includes an inlet portion narrower than a lateral width of the belt in the specific upper surface side plate member constituting the hook. In addition, a notch including a belt holding portion that is wide from the inlet portion is formed, and the locking portion is configured to have a size that cannot pass through the belt holding portion and You may comprise from the attached rod-shaped member.

The bed laying board according to the present invention as described above can be used as a bed laying board having a cocoon-like shape excellent in air permeability, moisture absorption, etc., when the posture maintenance member is deployed in a horizontal position. In addition, the posture maintaining member can maintain the two cocoons in a tilted position, so even if a futon is placed on a bedbed in a tilted position, it can be used as a futon without changing the position to the use position. can do. Furthermore, the hooked portion provided on the hook and the hook provided on the posture maintaining member are locked and unlocked at substantially the intermediate position in the tilt direction of the hook and the two hooks are inclined. In addition to being able to change the posture easily and quickly into a folded posture, it will not be easy to release the locked state even if a person or an object collides with the kite, making it excellent in operability and reliability be able to.
In addition, since the upper surface side plate member of the kite has a plurality of vent holes, the vent holes can be ventilated to easily release moisture, heat, etc. from the futon and have excellent breathability. be able to.

  In addition, by making the hole on the upper surface side of the ventilation hole larger than the hole on the lower surface side, the contact portion between the ventilation hole and the futon is increased to improve the air permeability, and the hole on the lower surface side is changed to the hole on the upper surface side. By making it smaller than this, the strength of the plate member can be maintained.

  In addition, since there is a folding engagement portion on the side of the heel with respect to the engagement portion of the posture maintenance member, the single posture maintenance member switches the two lion folds between the folding posture and the inclined posture, and the posture is changed. Since these can be maintained, the number of members can be reduced compared to the case where the postures are maintained by separate posture maintaining members, which is advantageous in terms of cost.

  In addition, since each of the lower end of the two kites has a rotating body for movement that can rotate in contact with the floor surface, when the two kites are moved in a tilted or folded position Can be moved with little force without lifting or dragging the bed laying board, when storing the bed laying board in a folded position, or moving the bed laying board in a tilted position with a futon Can be easily performed with a small operating force.

  Since a plurality of sliding cloth members are provided on the upper surface side plate member located at the lower ends of the two scissors in the inclined posture, when moving the bed sheet for the inclined posture and the folded posture, The contact resistance with the floor surface is reduced, the sliding is improved, and it is possible to move with very little force. Moreover, since the cloth member is wound around the part which contacts the floor surface, it is difficult to damage the floor surface. This is particularly advantageous when the floor surface is moved (sliding) while dragging (sliding) a carpet or tatami mat having a large contact resistance.

  By providing a plurality of foot members on the lower surface of the lower surface side plate member, less material is required compared to a case where a single long lower surface side plate member has a predetermined thickness with the floor surface. This is advantageous in terms of cost. In addition, a large number of spaces (gap) can be provided between the floor surface and the lower surface side plate member with which the floor laying plate comes into contact with a plurality of foot members. The air permeability in the hand direction can also be improved.

  A bar-like member provided in the locking portion is formed on the upper side plate member by forming a notch including an inlet portion narrower than the belt width of the posture maintaining member and a belt holding portion widened from the inlet portion. By simply configuring the belt holding part to be longer than the width of the belt holding part, the locking part can maintain the locked state without coming out of the locked part, and is more cost-effective than a special locking part. Is advantageous. In addition, since the posture maintaining member has a belt shape and is flexible and is configured to be wider than the lateral width of the inlet portion, the belt is bent by hand and inserted into the belt holding portion from the inlet portion. The belt is held by the belt holding portion, and the locked state can be realized easily and quickly. In addition to maintaining the tilted posture, the locked state can be maintained even when moved or carried using a rotating body, so that the locked state can be released without permission during work. There is no.
