Abstract

PURPOSE:To smoothly turn a nonbearing partition panel, by, connecting a pin- supporting member in the conditions that the longitudinal directions of the side parts of the panels each are matched to center pins and that the surfaces of friction wheels are brought into close contact with each other. CONSTITUTION:Friction wheels 3 each are installed to the upper and lower ends of stiles 12a of partition panels 1, which stiles are opposed to each other. At this time, in the conditions that through-holes 51 on a pin-supporting member 5 are matched to a pierced hole 63 on each of the friction wheels 3 and that the friction wheels 3 are brought into close contact with each other, center pins 7 each are inserted into the friction wheels 3. The friction wheels 3 each are tightened with the center pins 7 and are fastened so as not to turn. When one of the panels 1 is fixed and the other of the panels 1 is turned, the friction wheel 3 on the other of the panels 1 is turned centering around the center pin 7 for the friction wheel 3 on the one of the panels 1. At this time, the friction wheels 3 are made of rubber or synthetic resin, and a coefficient of friction is made larger, and thus the friction wheels 3 are prevented from slipping. In this way, the structure of the panels is simplified and the panel 1 can be prevented from deviating from the direction of turning.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a movable panel screen for partitioning a space such as an office.

[0002]

2. Description of the Related Art Conventionally, in a panel screen of this type, for example, two single panels are rotatably connected to each other by joint portions provided at the upper and lower ends of their side edges. The stand-alone panel is attached to both ends of the stand, the frame that supports the panel from its surroundings, the stand that is fixed to the lower edge of the frame in a state that it protrudes in the lateral direction and becomes the leg of the stand-alone panel. Composed of casters and casters. Further, the joint portion is composed of a gear fixed to the upper end of the vertical member of the frame, and a connecting member for connecting the rotating shaft portion serving as the rotation center of the gear.

In such a structure, in order to change the partitioning of the room, one of the unit panels is supported so as not to move, and the other unit panel is pushed in the moving direction.
Or when pulled, centering around the rotary shaft connected by the connecting member of the other single panel, the single panel rotates and moves in the desired direction, and the angle of the two single panels is changed, It can be a different partition than before.

[0004]

In the panel screen having the above-mentioned structure, since a considerable stress is applied to each gear when the single panel is moved, the gear is required to have high strength. For this reason, for example, a die-cast gear is used as the gear, but when the teeth do not have a uniform shape or are distorted, the gear may make a clicking sound when rotated. Normally, the meshing part of this gear is exposed, and with a relatively short single panel, there is a possibility that fingers etc. may be caught in the meshing part, which was a problem from the viewpoint of safety. .

An object of the present invention is to eliminate such a problem.

[0006]

The present invention takes the following means in order to achieve such an object. That is, the panel screen according to the present invention is a panel screen in which at least two single-piece panels movable on the floor are rotatably connected to each other by connecting means at a side edge portion of each single-piece panel. The means is a columnar friction wheel having a large friction coefficient on its surface, which is mounted non-rotatably with its central axis aligned with the longitudinal direction of the side edge portion of each single panel, and the surfaces of the friction wheels are in close contact with each other. And a shaft support member that rotatably supports the central shaft in this state.

The friction wheel of the present invention is preferably non-rotatably attached to the upper and lower ends of the side edges of the unitary panel.

[0008]

With such a structure, the friction wheels, which are non-rotatably attached to the individual unit panels, have their surfaces brought into close contact with each other by the shaft supporting member. Then, when one of the unit panels is fixed and the other unit panel is rotated, the other unit panel rotates about the center axis of the friction wheel attached to the one unit panel. Will be done. In this case, since the surface of each friction wheel has a large friction coefficient, no slip occurs between the friction wheels. Therefore, the other single panel rotates around the side edge of the one panel, and at that time, the side edge of the other single panel and the side edge of the one single panel form the single panel. The position is prevented from shifting due to movements unrelated to the rotation direction, such as overlapping in the thickness direction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. The panel screen shown in FIG. 1 is configured by three unitary panels 1 being rotatably connected to each other by a connecting means 2. The single unit panel 1 includes a rectangular flat panel 11, a frame 12 including a vertical frame 12a that supports the panel 11 from its periphery, and upper and lower horizontal frames (not shown), and a lower edge of the lower horizontal frame of the frame 12. And a caster 14 attached to both ends of the stand 13, which is a leg of the single unit panel 1 and is fixed so as to project in the lateral direction. The unitary panel 1 itself may have a structure widely known in this field. The upper ends 1 of the left and right vertical frames 12a of the frame 12
A friction wheel 3 constituting the connecting means 2 is selectively attached to the 2u and the lower end 12l. Edge members 12b are attached to the upper and lower horizontal frames, and the surfaces thereof are covered. In addition, in FIG. 1, in order to show the connection means 2, the edge part 12b is cut away and shown.
In practice, the edge member 12b covers the upper side of the connecting means 2 (shown in phantom in FIGS. 2 and 4).

The connecting means 2 comprises a friction wheel 3 and a shaft supporting member 5, and is attached to the upper end 12u and the lower end 12l of the vertical frame 12a of the frame 12 forming the side edge portion of the unitary panel 1. The friction wheel 3 of the connecting means 2 controls the positional displacement when the single panel 1 is rotated due to the large frictional force on the surface thereof, and basically does not generate a large stress. Absent. The friction wheel 3 of this embodiment is formed by attaching a rubber or synthetic resin sheet 31 having a large frictional force to a recess formed on the surface of a metal base 6. Such a base 6 has a semi-cylindrical portion 61 on the front side, that is, on the opposite side when attached to the single panel 1.
The prism 62 is integrated in the rear of the semi-cylindrical 61, that is, on the side facing the single unit panel 1, and the central axis 7 is provided in the longitudinal direction at the center of the semi-cylindrical 61. A through hole 63 to be inserted is provided. Then, in the central portion of the semi-cylindrical 61 in the vertical direction, the sheet 31 having a predetermined width is
However, it is attached by embedding a thickness of about 2/3 in the semi-cylindrical 61. The surface of the sheet 31 may be as it is as long as the material has a large friction coefficient, but the surface may be processed to increase the friction coefficient.

The friction wheel 3 is non-rotatably attached to the upper and lower ends 12u and 12l of the vertical frames 12a of the central and left and right unitary panels 1 facing each other.
That is, these are mounted by mounting the shaft support member 5 having the through hole 51 of the diameter into which the central shaft 7 of the friction wheel 3 can be inserted into the oval flat plate, and the through hole 51 through the through hole 63 of the friction wheel 3. The respective central shafts 7 are inserted into the friction wheel 3 in a state in which they are brought into close contact with each other and are brought into close contact therewith. In this manner, the friction wheel 3 has the prism 62 portion of the base 6 closely attached to the panel 11 to function as a detent. Therefore, by tightening with the central shaft 7, the upper end 12u and the lower end 12l of the vertical frame 12a of the frame 12 are secured. It is attached so that it cannot rotate. The central shaft 7 has a screw 72 formed on its lower end 71,
The friction wheel 3 is fastened by being screwed into a screw provided on the vertical frame 12a of the frame 12. In such a mounted state, the surface of each friction wheel 3, that is, the sheet 31, is in close contact with each other, restricts the mutual movement of the unit panels 1, and the respective central shafts 7, 7
Is rotatably supported by the shaft support member 5 and is restricted from separating.

In the above construction, when the individual unit panels 1 are arranged in a straight line, the connecting means 2 is
As shown in FIG. 3A, the surfaces of the two friction wheels 3 are
It is almost in point contact. That is, in this case, only the surface corresponding to the side edge of the single panel 1 is in intimate contact, and one friction wheel 3 slides due to the frictional force therebetween, so that the single panel 1 is only at its side edge portion. It does not shift to the overlapping position. When the single unit panel 1 is rotated, specifically, for example, when the left single unit panel 1 is rotated to the front side of the central single unit panel 1, the friction wheel 3 of the central single unit panel 1 and the left single unit panel 1 are rotated. Since the frictional force between the frictional wheel 3 and the first frictional wheel 3 is large, the frictional wheel 3 of the left-side single unit panel 1 moves on the surface of the frictional wheel 3 of the single-sided panel 1 in the center while repeating substantially point contact. At this time, the two friction wheels 3 and 3 are substantially in point contact with each other, but since the frictional force is large, there is no displacement from the point contact position,
Therefore, the single panel 1 on the left side is smoothly rotated to a desired position.

As described above, the connecting means 2 includes the single panel 1
Placed at the upper and lower ends of each unit panel 1
Since the positional deviation during rotation of the single unit panels 1 is regulated, even if the vertical central portions of the individual unit panels 1 are not rotatably connected by means of hinges or the like, the front and left sides of the central single unit panel 1 It does not shift to a position where the back surface of the single unit panel 1 is flush. Further, since the connecting means 2 regulates the positional displacement during rotation of the single panel 1 due to the friction of the two friction wheels 3, it does not produce any sound when rotating and is quiet and smooth. The position of 1 can be changed. Further, since the surface of the friction wheel 3 is not uneven like a gear, it is not possible to imagine a mechanical one from the appearance, and the shape of the frame 12 is a semi-cylindrical shape as in this embodiment. If it is integrated with the prism, it can be made to look like a part of the vertical frame 12a of the frame 12 even if it is exposed, and it can be blended into the overall design of the panel screen. Furthermore, it is also possible to decorate the surface of the sheet 31 with a groove or the like after securing a portion that makes a substantially point contact that can exhibit sufficient frictional force to prevent displacement when rotating. Can be matched.

The present invention is not limited to the above-described embodiments, and the friction wheel 3 has a metal base 6 on which a material having a high friction coefficient is stuck, as in the above-described embodiments. In addition to the above materials, the base material 6 and the sheet 31 in the above-described embodiment may be integrally formed as long as the material itself has a high coefficient of friction and is a material having good moldability and high rigidity. Further, the attachment position of the connecting means 2 is not limited to the upper end 12u and the lower end 12l of the vertical frame 12a in the above embodiment, but may be attached near the upper and lower ends of the vertical frame 12a.

In addition, the configuration of each part is not limited to the illustrated example, and various modifications can be made without departing from the spirit of the present invention.

[0016]

As described above in detail, the present invention uses a friction wheel having a large frictional force on the surface as a connecting means for two single panels, so that the structure is very simple. Moreover, when the single unit panel in which the friction wheel is non-rotatably attached is rotated, the frictional force of the surface of the friction wheel can prevent the single panel being rotated from being displaced in a direction other than the rotation direction.
