JP4667034B2 - Bed frame with double storage box - Google Patents

Description

  The present invention relates to a double frame type bed frame with a storage box.

It has a rectangular panel-shaped bottom on a rectangular storage box that opens upward, and a rotation link is provided between the inner surface in the longitudinal direction on the head side of the storage box and the bottom, and closer to the foot than the rotation link. There is a bed frame that uses the inside of the storage box as a storage space by rotatably mounting an outer frame bottom opening / closing gas cylinder between the storage box and the bottom and opening and closing the bottom from the foot side.

When using a mattress on a bed frame with a storage box as described above and using it as a bed, the space on the entire bottom bottom surface is used as a storage compared to a bed frame with a drawer that has a drawer under the conventional bed frame. Since it can be used, it can be used to store long items and large and bulky items such as futons and blankets.

In the case of the above bed frame with a storage box, the pressure of the gas cylinder is set so that the weight balance can be achieved with the mattress placed, so the bottom part will automatically turn up and down when the mattress is removed. Due to the danger, some have a releasable stopper device that fixes the rotation when the bottom is in a horizontal state between the storage box on the foot side and the bottom.

However, in the case of the bed frame with a storage box described above, the opening and closing operation of the bottom is limited to only one side in the longitudinal direction of the bed. The opening and closing part of the door is small, the rotating link becomes in the way, and it is not easy to put in and out the stored item, and there is a risk that hands will be caught in the rotating link if the bottom descends when putting in or out the stored item For this reason, there is a drawback in that the storage space behind the opening and closing of the bottom cannot be fully utilized while having a large storage space. With respect to the casement stow structure, already include the Patent Document 3, to assist the weight of the mattress and the bottoming-time by opening and closing operation considering the technical application to Bed sides open in the direction of gravity and against facing If there is no such thing as a gas cylinder, there are drawbacks that must all be done by the user's arm strength .

When the bottom 2 is undulated from the other end side 7 in the longitudinal direction by rotatably attaching the inner bottom opening / closing gas cylinders 10 and 10 ′ between the outer frame bottom 3 and the inner bottom 4 on both sides closer to 5 The outer frame bottom 3 and the inner bottom 4 are on the other end side 7 in the longitudinal direction. Since it is connected at the moving point 9, the inner bottom 4 alone cannot be rotated, and the outer frame bottom 3 is integrally pivoted up and down. Conversely, when the bottom 2 is pivoted up and down from one end in the longitudinal direction, Since the storage box 1 and the outer frame bottom 3 are connected to each other by a rotation link at one end side 5 in the longitudinal direction, the outer frame bottom 3 cannot be rotated up and down, and only the inner bottom 4 has the rotation point 9 as a rotation axis. Due to the structure of turning up and down, it is possible to turn up and down from the other side without limiting the turning up and down of the bottom 2 to only one side, long items and futons as stored items in the storage box 1, Even a bulky item such as a blanket can be safely and easily inserted and removed, and the space in the storage box 1 can be fully utilized as a storage space.

The bottom 2 includes an outer frame bottom 3 and an inner bottom 4, and the outer frame bottom 3 and the storage box 1 are rotatably connected to each other on both sides of the longitudinal one end side 5 by rotating links 6, 6 '. The outer frame bottom opening and closing gas cylinders 8 and 8 ′ are rotatably mounted between the outer frame bottom 3 and the storage box 1 on both sides closer to the other end side 7 in the longitudinal direction than the rotation links 6 and 6 ′. The inner bottom 4 is rotatably connected to the outer frame bottom 3 on the other end side 7 in the longitudinal direction, and the outer frame bottom 3 and the inner side on both sides closer to the one end side 5 in the longitudinal direction than the connected pivot point 9. Since the inner bottom open / close gas cylinders 10 and 10 ′ are rotatably attached to the bottom 4, the bottom 2 can be rotated from either the longitudinal end 5 or the longitudinal end 7 of the bed frame. It was possible to move up and down.

    FIG. 1 shows an overall perspective view of an embodiment of the present invention. A storage box 1 is formed by connecting a pair of longitudinal plate bodies 12 and 12 'and a pair of width direction plates 13 and 13' by a connecting metal fitting 14.
