[Industrial applications]

 The present invention relates to a drawer lifting device for a storage unit in storage furniture, which can effectively use a high storage space and improve usability.

[0002]

[Problems to be Solved by Prior Art and Invention]

 Today, it is not easy to secure sufficient storage space in houses, so effective use of dead space near the ceiling is proposed. However, the storage space near the ceiling is high and not easily accessible, so you have to prepare ladders and stepladders each time you take items in and out, and you must climb and descend ladders and stepladders while holding objects. As a result, there was a risk that the loading and unloading of goods would be a labor-intensive task, and that there would be a safety problem.

Therefore, it has been proposed to assemble a storage unit provided near the ceiling in a storage box so that the storage unit can be pulled out and moved up and down. In that case, if the storage unit is moved up and down electrically, it is expensive. Not only an electric motor is required, but also the raising and lowering position must be controlled, which complicates the structure and raises the cost.Therefore, there is a demand for only an optional motor, and there is a need for manual operation. It will be necessary to configure it to raise and lower. However, in the case of manual operation, since the lifting and lowering is performed while supporting the own weight of the storage unit, a large amount of labor is required for the lifting and lowering work, and the operability is extremely poor.

[0004]

[Means for Solving the Problems]

 SUMMARY OF THE INVENTION The present invention was devised with the object of providing a drawer unit lifting / lowering device for a storage unit that can eliminate these drawbacks in view of the above-mentioned circumstances. In a storage furniture comprising unit withdrawing means for freely storing the storage unit and unit elevating and lowering means for elevating and lowering a storage unit withdrawn from a storage box, the unit elevating and lowering means guides the storage unit up and down. And a constant-torque ammunition provided between the storage unit and the storage box for constantly urging the storage unit in the upward direction.

According to the present invention, with this structure, the storage unit can be manually moved up and down, but the labor thereof can be greatly reduced.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 is a shoe storage furniture installed at a front door, etc., which is tall enough to reach from the floor to the ceiling, but the storage furniture 1 is opened and closed by a double door type door 2. The box-shaped storage box 3 is formed into a box-shaped storage box 3, and various storage units such as storage units 4 and 5 can be appropriately combined and stored in the box. Among them, the storage unit 4 to be housed at a high place is in the form of a multi-tiered shelf, and one side 6a of each of a pair of upper and lower hinges 6 is integrally fastened to the side corners thereof. However, the other side 6b of the hinge 6 is extended in the left-right direction in the embodiment. The other side 6b of the hinge is reinforced by a plate-shaped reinforcing member 7a to form the elevating member 7 of the present invention. On the back surface of the elevating member 7, guide rollers 8 are provided vertically and horizontally. Is pivotally supported. On the other hand, a pair of front and rear guide rails 9 are formed on the inner side surface of the side 3a of the box-shaped storage box 3 in which the storage unit 4 is stored. The guide roller 8 is installed so as to face in the direction, and the guide roller 8 is vertically guided by the guide rail 9. In the storage unit 4, the guide rollers 8 are positioned above the guide rails 9 when stored in the storage box 3, and from this storage state, the hinges 6 serve as spindles to move them out of the box (front side). It swings so as to be pulled out, and when the guide roller 8 is moved downward along with the guide rail 9 in the pulled-out posture in which it is pulled out toward the front side, it can be displaced to a lower pull-down position as described later. As a result, it is possible to properly take in and out the stored items such as shoes at the pulling-down position.

Next, the elevating device 10 of the storage unit 4 will be described. A casing 10a that constitutes the elevating device 10 is incorporated in a ceiling corner portion of the storage box 3. Inside the casing 10a, three sets of constant torque ammunition (constant springs), which are configured by using plate-shaped spiral ammunition, are installed. It is integrally fixed to the lifting member 7 by using a fastening member 12 such as a rivet. The above-described raising and lowering movement of the storage unit 4 in the pulled-out state is set so that the biasing force of the constant torque ammunition 11 which constantly acts in the winding direction and the own weight of the storage unit 4 are balanced. However, in this case, the biasing force of the constant torque ammunition 11 is set to be slightly larger than the own weight of the storage unit 4, and is set so as to be approximately balanced with the own weight of the items stored in the storage unit 4. Has been done.

Further, a cylindrical bracket 13 is integrally fixed to the back surface of the other side 6b of the hinge (may be the reinforcing member 7a), and the coil 13 is attached to the bracket 13. A ball 15 which is always urged in the protruding direction by 4 is housed so as to be retractable. The ball 15 is placed in at least two upper and lower limit positions of the storage unit 4 and, if necessary, at the ball position corresponding to the intermediate position of lifting and lowering, the ball 15 is provided in the locking hole 16 provided on the inner side surface of the storage box 3 with a light weight. By fitting, the storage unit 4 can be temporarily held lightly at the corresponding position.

In the embodiment of the present invention configured as described above, the storage unit 4 is stored at a high place in the storage box 3 so as not to get in the way. If desired, after the door 2 is opened, the storage unit 4 can be pulled out from the inside of the box with the hinge 6 as a pivot, and the pulled-out storage unit 4 can be pulled down. While it is stored in place, it can be taken in and out at a low position, and it does not require a footrest such as a stepladder as in the past.

As described above, in the embodiment of the present invention, the storage unit 4 is provided so that it can be freely pulled out from the storage box 3 and can be moved up and down so that the storage unit 4 is at a high position while it is stored at a low position. While the storage unit 4 can be lifted up and down, it is balanced by the constant torque ammunition 11 to the weight of the storage unit 4 when stored. As a result, the raising and lowering operation of the storage unit 4 is light, and the operability is excellent, and an excessive burden is not imposed when raising and lowering.

In addition, in this case, since the storage unit 4 is held lightly by the balls 14 at least at two positions, the upper limit position and the lower limit position, when the stored items are too heavy or too light, the constant torque bullet is used. There is an advantage that the storage unit 4 can be prevented from being inadvertently raised and lowered due to the urging force of the machine 11.

[Operation effect]

 In short, since the present invention is configured as described above, when the storage unit is to be put in and taken out from the storage unit which is stored in a high place in the storage box so as not to disturb the storage unit, It is only necessary to pull it down from the inside of the box and pull it in and out at a low position.As a result, the inside and outside of the box is stored while making effective use of the high space close to the ceiling, while the work is carried out. Can be performed in a low position, which is easy to do, and does not require a footrest such as a stepladder as in the past. Moreover, since the storage unit is biased to the ascending side by the constant torque ammunition, it is possible to perform the raising / lowering operation of the storage unit in a state in which the constant ascending force of the constant torque ammunition always bears. It is light and easy to operate, and does not impose an excessive burden when going up and down.
