移動を容易ならしめるようになっている。2. Description of the Related Art FIG. 16 shows an example of a conventional caster in which a rolling wheel b grounded to a floor surface a is pivotally supported by a pair of left and right lower ends of a bifurcated bracket c. The upper end portion of the bracket c is attached to the flat mounting member d so as to be swingable about the rotation axis A, and the mounting member d is a supporting object such as furniture, a cargo bed, and machinery. The support object e is attached to a ground contact point with the floor surface a at the point e, so that the movement of the support object e on the floor surface a is facilitated.

ようになっている。[0003] In this type of caster, a vertical line B passing through the center of rotation of a rolling wheel b and a turning axis A of a bracket c are displaced from each other.
When the object is pushed by hand, the pivot axis A side is moved in advance together with the support object e, thereby guiding the vertical line B side to follow from the rear, corresponding to the moving direction of the support object e. The bracket c can be swung favorably in the direction as described above.

性が非常に高くなって危険である。However, in the conventional caster using the rolling wheel b, since the positional deviation between the turning axis A and the vertical line B is set as described above, the caster is directly above the turning axis A. The problem is that the downward load C is likely to cause a tipping moment like the arrow D starting from the center of rotation of the rolling wheel b. Particularly, the weight of the supporting object e itself is light and the turning axis A If a downward load is locally applied to a position spaced away from the vertical line B with respect to the vertical line B, there is a high possibility that the object to be supported e will fall over, which is dangerous.

った。Further, in the conventional caster using the rolling wheel b, a point contact (a line contact when the rolling wheel b is not crowned) at one point in the circumferential direction of the rolling wheel b with the floor surface a. As a result, it was easy to cause stress concentration, and there was a possibility that the floor surface a might be damaged when the heavy supporting object e was moved.

It is an object of the present invention to provide a caster which can be easily moved by sliding without damaging the floor.

る。According to the present invention, there is provided a lower disk having a substantially circular planar shape and having an eccentric shaft erected at a position deviated from the center position of the upper surface thereof, and a lower disk which slides on the upper surface of the lower disk. An upper disk which is freely mounted, has a substantially circular planar shape, and has an opening in which a play fitting hole for loosely fitting the eccentric shaft is formed at the center thereof; and a planar shape larger than the play fitting hole at the upper end of the eccentric shaft. A locking plate mounted so as to form the eccentric shaft to prevent the eccentric shaft from being pulled down; and a sliding plate mounted on the lower surface of the lower disk and sliding only in a direction coinciding with the eccentric direction with respect to the center position of the eccentric shaft. A caster, comprising: a direction-controlling sliding member to be generated; and a mounting member mounted on the upper surface of the upper disk so as not to restrain the locking plate to form a mounting structure for a support target. is there.

る。[0008] When such a caster is mounted on the grounding point of the support object with respect to the floor surface via the mounting member to support the support object, the load of the support object is reduced by the lower surface of the lower disk. And the lower surface of the upper disk is stably mounted in surface contact with the upper surface of the lower disk. The risk of generating a falling moment as described above and the risk of damaging the floor surface are eliminated.

じて該支持対象物の移動が容易となる。Further, when moving the object to be supported, since the direction-controlling material on the lower surface of the lower disk has directionality, the moving direction of the object to be supported does not coincide with the sliding direction of the direction-controlling material. However, friction occurs between the floor and the direction-controlling material, but the eccentric shaft is immediately guided in the moving direction following the movement of the support object, so that the sliding direction of the direction-controlling material is supported. The lower disk naturally swings around the eccentric axis so as to follow the moving direction of the object, thereby causing the supporting object to slide in the moving direction, thereby facilitating the movement of the supporting object.

合成樹脂板により構成したりすることが可能である。Here, as shown in FIGS. 9 and 10, for example, the direction regulating sliding member 11 regulates the sliding direction (the direction indicated by the arrow x in FIG. 9) by moving the bristle feet in one direction. As shown in FIGS. 11 and 12, a plurality of ridges 11a are directed in one direction to regulate a sliding direction (a direction indicated by an arrow x in FIG. 11). It can be made of a synthetic resin plate.

A mounting member 13 (see FIGS. 13 and 14) in which a space 12 for moving the locking plate 10 is secured so as not to restrain the locking plate 10.
) Is mounted on the lower part of the mounting member 13, and the upper part of the mounting member 13 is a male screw part 14 which can be screwed into a screw hole formed in the lower surface of the support leg of the support target 2. Are erected to form an attachment structure for the support target 2.

Is attached to the screw hole on the lower surface of the support leg of the support
When the supporting object 2 is supported by screwing the male screw portion 14 of the supporting member 2, the load of the supporting object 2 is stably supported by the lower surface of the lower disk 4 in surface contact with the floor surface 3. In addition, since the lower surface of the upper disk 7 is stably mounted on the upper surface of the lower disk 4 by surface contact with the upper surface of the lower disk 4, there is a possibility that a turning moment like a caster using a conventional rolling wheel is generated. And the possibility of damaging the floor 3 is eliminated.

振り旋回し、これにより支持対象物2の移動方向へ向け
た滑りが生じて該支持対象物2の移動が容易となる。In moving the support object 2, the direction of movement of the support object 2 and the sliding direction of the direction control slide material 11 are controlled because the direction control slide material 11 on the lower surface of the lower disk 4 has directionality. Does not coincide with each other, friction occurs between the floor surface 3 and the direction regulating sliding member 11, but the eccentric shaft 5 is immediately guided in the movement direction following the movement of the support target object 2, As shown in FIG.
The lower disk 4 naturally moves with the eccentric shaft 5 as a base so that the sliding direction (direction indicated by an arrow x in FIG. 15) of the object is along the moving direction of the support target 2 (direction indicated by an arrow y in FIG. 15). The object 2 swings and swings in the moving direction of the supporting object 2, thereby facilitating the movement of the supporting object 2.

ことができる。Therefore, according to the above-described embodiment, the object to be supported 2 can be stably supported on the floor surface 3 by surface contact, so that the occurrence of a falling moment like a caster using a conventional rolling wheel is prevented. And the safety can be greatly improved. In addition, as in the case of the caster using the conventional rolling wheel, the supporting object 2 can be gently lightened even with a small force.
Can be easily moved without damaging the floor surface 3.

できる。Furthermore, since the lower disk 4 and the upper disk 7, which are formed in a substantially circular plane shape, are superimposed on each other to give an appearance of an aesthetically pleasing geometric shape. It can be applied without deteriorating the design aesthetics, etc., and it is easy to fit in the cross section of the support legs such as furniture,
The existence of the casters 1 can be made inconspicuous.

If you draw a piece of furniture that is slid into a gap between other pieces of furniture, etc., and pull out the drawer toward you, the woolen fabric is inverted in the direction of the drawer. Since friction occurs, it is possible to reliably prevent a problem that furniture is drawn out together with the drawer.
