Description

  The present invention relates to a baby bed structure that can be recombined from a baby bed to other uses such as a middle circle.

  In general, a crib is used to lay an infant, and when it is no longer needed after the infancy, it is disassembled in each household and stored in a closet or the like.

  However, since the baby bed is bulky even if it is disassembled, it is difficult to store the baby bed even if it is stored in a closet or a storage room.

  Therefore, conventionally, a pair of left and right side frames, a rear frame that is detachably provided at both ends in the width direction with respect to one end in the width direction of both side frames, and a width of the other end in the width direction of both side frames. Surrounded by an upper front frame with both ends in the width direction detachably attached to the upper part and a lower front frame with a door with both width direction ends detachably installed at the lower part of the other width direction of both sides frame A bent frame body to be bent is formed, and a bed bottom plate is detachably provided at an inner intermediate portion of the bent frame body, and two storage bottom plates are detachably attached to the inner bottom portion of the bent frame body. On the other hand, the bed bottom plate, the storage bottom plates, the upper front frame and the lower front frame with doors are removed from the baby bed, respectively. A pair of left and right auxiliary rails, each of which is detachably connected to each other in the width direction, A rear frame that is detachably provided at both ends in the width direction at right angles to the other widthwise end of either one of the auxiliary frames, and an upper portion of the other widthwise other of the both side frames and both auxiliary frames An upper front frame that is horizontally detachable at both ends in the width direction, and a door that is horizontally detachable at both ends in the width direction at the other end of the other side frame and both auxiliary frames. The middle circle surrounded by the lower front frame can be formed, and the crib is disassembled. Both auxiliary frames and the widthwise ends of both auxiliary frames are perpendicular to each other. Of the rear frame provided detachably, and the bottom plate for both storages detachably provided in the inner middle part of the substantially U-shaped frame body in plan view formed by both the auxiliary frame and the rear frame And a lower front pedestal with a door that is laid horizontally at the lower end of the other widthwise end of both auxiliary pedestals. There is known a baby bed structure that can be formed into a bench, and that a rack can be formed by detachably providing the other of the storage bottom plates on the inside upper part of the bench frame. (See Patent Document 1).

Japanese Patent No. 3585475

  By the way, such a baby bed structure can be recombined for other uses such as a middle circle, a bench or a rack in addition to the baby bed. The width direction support | pillar extended in the width direction is provided, and the vertical direction support | pillar extended in the up-down direction is connected with the both ends of this width direction support | pillar.

  In that case, when reassembling each frame according to the crib, middle circle, bench, or rack, the frames that are adjacent to each other in the width direction are always connected by the vertical columns. For this reason, when any of cribs, middle circles, benches or racks is formed, there are always two vertical columns at the connecting part at the corners of the frames adjacent to each other in the width direction. Since it was an assembled product, the rugged impression could not be wiped off, and it was far from a delicate impression such as a molded product in which cross frames adjacent to each other in the width direction were integrally connected.

  In addition, if two vertical support columns are always arranged in the connecting portion at the corners of the frame frames adjacent to each other in the width direction, the cost of the frame frame is high and the cost of the baby bed structure is reduced. I can't.

  The present invention has been made in view of such a point, and an object of the present invention is to give a delicate impression like a molded product in which crosspieces adjacent to each other of a crib are integrally connected. Another object is to provide a baby bed structure that can be reduced in cost by reducing the cost of one of the frames that are adjacent to each other in the width direction and that can be recombined for other uses. .

  In order to achieve the above object, according to the present invention, a pair of left and right side frames, a rear frame that is detachably provided at both ends in the width direction at right angles to one end in the width direction of the both side frames, An upper front frame having both ends in the width direction detachably placed at the upper part of the other end in the width direction of the frame, and a door having both ends in the width direction detachably provided at the lower part of the other end in the width direction of the both side frames. A bendable frame body is formed to be surrounded by the front lower frame of the lower part, and a bed bottom plate is detachably provided at an inner middle portion of the bendable frame body, and two pieces are provided at an inner bottom portion of the bendable frame body. The cradle can be detachably juxtaposed side by side to form a crib. On the other hand, from the crib, the bed bottom plate, the two storage bottom plates, the upper front frame, and the lower front frame with doors can be formed. Each frame is removed, and both side frames and one end in the width direction of each side frame are A pair of left and right auxiliary frames that are detachably connected to each other, and the rear in which both ends in the width direction are detachably provided at right angles to the other widthwise ends of either one of the both side frames and the both auxiliary frames. A frame, the upper front frame having both ends in the width direction detachably placed on top of the other widthwise other end of either side frame or both auxiliary frames, the both side frames, It is possible to form a middle circle surrounded by the lower front pedestal with the door, in which both ends in the width direction are detachably provided at the lower part of the other widthwise other end of either of the auxiliary frames, and further, the baby Disassembling the bed, both the auxiliary frame, the rear frame provided detachably at both ends in the width direction at right angles to one end in the width direction of both auxiliary frames, the both auxiliary frames, The inner middle part of the substantially U-shaped frame in plan view formed by the rear frame A bench can be formed by one of the two storage bottom plates provided detachably and the lower front frame with a door horizontally provided at the lower part of the other widthwise end of the auxiliary frames. A baby bed structure that can form a rack by detachably providing the other of the storage bottom plates to the inside upper portion of the bench frame is assumed. And the width direction support | pillar extended in the width direction of each said frame is provided in the up-and-down both ends of each said frame, The both ends of the width direction support | pillar of the said both-side frame, the said upper front frame, and both said auxiliary frames The vertical struts extending in the vertical direction are connected to each other, and both ends of the width-direction struts of the rear frame and the lower front frame with the door are connected to the crib, the middle circle, When the bench or the rack is formed, the bench or the rack is connected to a vertical column of either of the side frames and the auxiliary frames through a connector.

  Also, in the connecting tool, vertical struts in the vertical direction of the rear frame and the lower front frame with a door through a through-hole penetrating the left and right vertical columns of the both side frames and the auxiliary frames in the front and back direction.

  The upper front frame is supported on the upper front end of the both side frames so as to be slidable downward, and the lower front frame with a door is positioned on the back side of the upper front frame. You may attach to the front end lower part of a frame.

  Further, a plurality of the auxiliary frames may be arranged in the width direction, and the left and right vertical columns may be connected to each other via a fastener.

  Furthermore, it is preferable that the length of the two auxiliary rail frames arranged in the width direction is matched with the length of the side rail frames in the width direction.

In short, in general, a baby bed is usually laid with a futon or the like on the bed bottom plate. In addition, when the baby grows and the crib is no longer needed, the crib can be disassembled, and each frame can be recombined to form a middle circle so that infants can play in the middle circle. is there. Further, the baby bed can be used as a bench or a rack by recombining each frame, and the baby bed that is no longer needed is reused as a middle circle, a bench, or a rack.
In that case, vertical struts are connected to both ends of the width direction struts of the width direction struts of both the top and bottom end width frames of each frame, the upper front frame, and both auxiliary frames, and the rear of each frame When forming the crib, middle circle, bench, or rack at both ends of the width direction strut of the frame and the lower front frame with a door, it becomes a vertical strut of either side frame or both auxiliary frames. On the other hand, by connecting via a connecting tool, two vertical columns are not necessarily lined up at the connecting part at the corners of adjacent frames, and the rugged impression due to the assembly is wiped away. It is possible to give a delicate impression like a molded product obtained by integrally connecting the frame frames. In addition, two vertical support columns are not necessarily lined up at the connecting portion at the corners of the frames that are adjacent to each other in the width direction, so that the cost of one frame of each frame can be reduced. The price of the bed structure can be reduced. Furthermore, the rear frame and the lower front frame with a door can be connected to the vertical column of either of the two frames or the auxiliary frame by a vertical support column through the coupling tool so as not to be twisted. The bed, middle circle, bench and rack can be assembled firmly without rattling.

  Also, through the through holes that penetrate the left and right vertical struts of both side frames and both auxiliary frames, the holes are drilled at the both ends of the top and bottom width columns of the rear frame and the lower front frame with a door. The screw hole on the side of the nut member that the male screw of the bolt member is inserted into the receiving hole recessed from one side in the front and back direction of the rear frame and the lower front frame with the door so as to be orthogonal to the drilled hole Both ends of the width direction struts of the rear frame and the lower front frame with a door can be connected to the vertical columns of either of the both side frames and the auxiliary frames. .

  Also, support the upper front frame to the upper front end of both sides so that it can slide downward, and attach the lower front frame with doors to the lower front end of both side frames located on the back side of the upper front frame. Thus, the upper front frame can be smoothly opened and closed by sliding downward on the upper front ends of the both side frames.

  In addition, a plurality of auxiliary pedestal frames are juxtaposed in the width direction by connecting adjacent left and right vertical columns of the auxiliary pedestal frames arranged in the width direction via fasteners. A part of the baby bed structure can be made more versatile.

  Furthermore, the two auxiliary frames can be used in place of the side frames by matching the length of the two auxiliary frames arranged in the width direction with the length in the width direction of the side frames. The versatility of the bed structure can be further enhanced.
