Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a chest for storing clothes, small articles and so on and a method of manufacturing the same. [0003] 2. Description of the Related Art [0004] Hitherto, a chest is used for storing clothes or small articles and so on. The chest is composed of a chest body and a drawer stored in the chest body so as to be capable of being drawn out therefrom. A chest of a type in which the chest body and the drawer are formed of synthetic resin by injection molding and the chest body has a frame structure considering manufacturing cost or manufacturability is also in the market. The chest of this type includes a chest body having a space surrounded by synthetic resin frames and a drawer which is fitted into the space in the chest body so as to be capable of being drawn out therefrom. [0005] However, when the chest body and the drawer as described above are molded with synthetic resin, the drawer is low...

AI Technical Summary

Benefits of technology

[0008] According to claim 2, the rails are formed of metal. Therefore, the movable members slide in the metallic rails having low sliding resistance and hence slidability of the drawer is improved.

[0009] According to claim 3, the rails are disposed on the lower portions of opposed side surfaces of the space. Therefore, the movable members are also arranged on the lower portion of the drawer, and hence reduction of capacity of the drawer can be alleviated in comparison with the case in which the movable members are provided on the upper portion of the drawer.

[0021] According to claim 4, the movable members in the drawer are also arranged on the bottom portion of the drawer, and hence reduction of capacity of the drawer can further be alleviated in comparison with the case in which the movable members are provided on the upper portion of the drawer.

[0011] According to claim 5, the chest body is provided with holding members that hold the rails in association with the power capacity of operation to assemble the rails. Therefore, an operator can assemble the rails easily with a simple operation with a light power.

[0012] According to claim 6, the chest body is provided with holding members that hold the rails in association with the power capacity of operation to assemble the rails, where the holding members include a plurality of holding strips which hold the upper and lower surfaces of the rails in press-contact thereto without protruding to the inner side of the rails. Therefore, the slidability of the movable members can be secured without interference or contact of the movable members sliding in the rails with respect to the holding strips.

[0013] According to claim 7, the chest body includes a pair of front and rear supporting column frames extending in the vertical direction on the left and right sides, the space is defined between these supporting column frames, and the rails are disposed between the pair of front and rear supporting column frames. Therefore, supporting rigidity of the supporting column frames extending in the vertical direction can be enhanced by effectively utilizing the rigidity of the rails.

[0016] According to the invention of claim 10, at the time of the injection molding, holding members for holding the rails in association with the fitting operation are formed on the chest body, and the rails are assembled to the holding members before the resin is cured. Therefore, since holding strips are in a soft state in which the resin is not completely cured at the time of assembly of the rails, the operator can complete a mounting work of the rails in a simple operation without any difficulty.

[0028] According to the invention of claim 11, the mounting work of the rails can be completed in a simple operation so as to interpose the rails between the plurality of holding strips in the uncured state.

[0018] As described the above, according to the invention of claim 1, when a user operates to open or close the drawer, the movable members on the drawer slide in the rails on the chest body. Therefore, slidability of the drawer in the chest in which the chest body is molded with synthetic resin can be improved, whereby the quality feeling and the user-friendliness of the synthetic resin chest of this type can be improved.

[0008] According to claim 2, the rails are formed of metal. Therefore, the movable members slide in the metallic rails having low sliding resistance and hence slidability of the drawer is improved.

[0020] According to claim 3, the movable members in the drawer are also arranged on the lower portion of the drawer, and hence reduction of capacity of the drawer can be alleviated in comparison with the case in which the movable members are provided on the upper portion of the drawer.

[0021] According to claim 4, the movable members in the drawer are also arranged on the bottom portion of the drawer, and hence reduction of capacity of the drawer can further be alleviated in comparison with the case in which the movable members are provided on the upper portion of the drawer.

[0022] According to claim 5, an operator can assemble the rails easily with a simple operation with a light power.

[0023] According to claim 6, the slidability of the movable members can be secured without interference or contact of the movable members sliding in the rails with respect to the holding strips. Consequently, the slidability of the movable members can be secured while fixing the rail in a simple structure.

[0024] According to claim 7, supporting rigidity of the supporting column frames extending in the vertical direction can be enhanced by effectively utilizing the rigidity of the rails and hence the rigidity of the entire frame can be enhanced, thereby improving the quality feeling of the chest.

[0025] According to claim 8, the chest body is completed easily by combining the plurality of frame units.

[0026] According to the invention of claim 9, since the resin is in a soft state before having completely cured at the time of assembly of the rails, the operator can complete a mounting work of the rails in a simple operation without any difficulty. Consequently, assembly of the rails can be completed in an injection molding line for the chest body without providing a specific line therefor.

[0027] According to the invention of claim 10, since holding strips are in a soft state in which the resin is not completely cured at the time of assembly of the rails, the operator can complete a mounting work of the rails in a simple operation without any difficulty.

[0028] According to the invention of claim 11, the mounting work of the rails can be completed in a simple operation so as to interpose the rails between the plurality of holding strips in the uncured state.

Problems solved by technology

However, when the chest body and the drawer as described above are molded with synthetic resin, the drawer is low in rigidity and hence is easily deformed and, in addition, sliding resistance generated between the chest body and the drawer is significant due to surface contact between synthetic resin parts.

Therefore, difficulty in sliding operation of the drawer is encountered, which may result in lowering of quality feeling and lowering of user-friendliness of the synthetic resin chest of this type.
