By fitting the bearing fitting 10 into the recess 5, the height of the lower surface of the housing 1 from the floor surface can be reduced.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a roller mounting structure for mounting a roller for casters on a lower surface of a cabinet of furniture such as a cabinet or a locker.

[0002]

[Prior art]

 Some conventional cabinets and lockers have rollers on the bottom surface of the housing to facilitate movement. The larger the diameter of such a roller, the easier it is to move the housing. However, the larger the diameter of the roller, the larger the height of the lower surface of the housing from the floor surface becomes. In cases where the height of the housing is limited, such as in mobile cabinets that can be stored downward, the volume of the storage area such as the drawer is reduced by the larger diameter of the roller. There is a problem that you have to do it.

Further, if the diameter of the roller is small, a large force is required to move the casing and the durability is deteriorated. Therefore, by fitting the bearing bracket that pivotally supports the roller into the recessed part provided on the lower surface of the housing, the height of the lower surface of the housing from the floor can be reduced even if the diameter of the roller is large. There are things that can be maintained. According to this, it is necessary to fit the bearing metal fitting into the recessed portion, insert the setscrew into the recessed portion by hand, and screw the bearing metal fitting into the housing. In addition, since the bearing fittings are mounted inside the recessed portion of which the size is limited, there is a problem that the support of the roller is likely to be unstable.

[0004]

[Problems to be solved by the device]

 In view of the above-mentioned problems of the conventional technology, the present invention allows a large-diameter roller to be easily and stably mounted without increasing the height of the lower surface of the housing from the floor. The purpose is to provide a roller mounting structure for furniture and the like.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the roller mounting structure for furniture of the present invention is provided with a recessed portion on the lower surface of a cabinet of furniture or the like, and the recessed portion is provided with a bearing fitting for pivotally supporting the roller with a horizontal pivot. It is characterized in that a fitting piece that fits and extends horizontally from the lower part of the bearing fitting to a depth approximately equal to the depth of the recessed part overlaps the lower surface of the housing and is screwed.

[0006]

[Action]

 When the bearing fitting is fitted in the recess, and the mounting piece is superposed on the lower surface of the housing and screwed, the upper end surface of the bearing fitting contacts the upper and lower end surfaces of the recess, and the roller is attached to the lower surface of the housing. It can be installed stably and screwing is easy. Further, by fitting the bearing fitting into the recess, the height of the lower surface of the housing from the floor can be reduced.

[0007]

【Example】

 The drawings show an embodiment of the present invention. For example, as shown in FIG. 4, a base plate (2) is stretched on the lower surface of a cabinet (1) such as a cabinet shown in FIG. A rectangular underframe (3) is continuously provided around the lower surface of the underplate (2).

Square recesses (5) are formed in front lower surface both sides of the frame rod (4) of the front part (left part of FIGS. 1 and 4) of the underframe (3) to form the frame rod (4). A reinforcing plate (6) is fitted inside the bracket), and a lateral concave portion (7) facing forward is formed on the front surface of the concave portion (5).

5 and 6 show a caster (8) used in the present invention, in which the pivot (9a) of the roller (9) facing in the left-right direction is located in the lower part of the front part of the bearing fitting (10). It is pivotally supported by both side pieces (11a) of the U-shaped pivot portion (11), a forward projecting portion (11b) is formed at the front edge of both side pieces (11a), and a rear portion of the center piece (11c) is An L-shaped mounting portion (12) is continuously provided.

The mounting piece (12a) of the mounting portion (12) is horizontally rearward from the lower portion by a distance substantially equal to the depth of the recessed portion (7) from the upper end of the central piece (11c) of the pivotal support portion (11). A plurality of through holes (13) for screwing and a positioning protrusion (14) are provided on the extending portion of the mounting piece (12a).

The caster (8) is fitted into the recessed portion (5) from below, and the central piece (11c) of the pivotal support portion (11) of the bearing fitting (10) is located at the central portion of the reinforcing plate (6). The protrusion (11b) fits into the lateral recessed portion (7), and the mounting piece (12a) of the mounting portion (12) is abutted against the upper rear end surface of the recessed portion (5) which is the lower surface. 4) The lower surface of the housing (1) is screwed into the nut (16) welded to the underframe (3) so that the set screw (15) that passes through the through hole (13) is overlapped with the lower surface of the housing (1). ) Is attached to the lower surface of the.

Although detailed description is omitted, the casters (8) are attached to the rear portion of the lower surface of the housing (1) in substantially the same manner as the front portion. With the configuration as in this embodiment, the following effects can be obtained.

[0013]

[Effect of device]

 (a) By fitting the bearing fitting into the recessed portion provided on the lower surface of the housing, the height of the lower surface of the housing from the floor can be kept low even if the diameter of the roller is large. It is not necessary to reduce the volume of the housing even for furniture whose height is limited.

(B) Since the mounting piece of the bearing fitting can be overlapped and screwed while being exposed on the lower surface of the housing, the screwing work can be performed easily and the entire mounting work is extremely easy. It's easy.

(C) The bearing fitting is fitted in the recess, and the mounting piece extending horizontally from the bearing fitting is screwed to the lower surface of the housing to fix the bearing fitting in the recess only. By doing so, the support of the roller is stabilized, and it is possible to prevent the bearing fitting from falling in the recessed portion or from changing the orientation of the axis of the roller.

(D) When the protruding portion of the bearing fitting is fitted into the lateral recessed portion formed on one side surface of the recessed portion, the fixing strength of the bearing fitting is increased to support the roller. Will be stronger.
