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 this type of panel screen, for example, two single panels are rotatably connected by joints provided at the upper and lower ends of the side edges. The unit panel is a panel, a frame that supports the panel from its periphery, a stand that is fixed to the lower edge of the frame in a state that it protrudes in the side direction and substantially becomes a leg of the unit panel, and attached to both ends of the stand And casters. The joint portion includes a spur gear fixed to the upper end of the vertical member of the frame, and a connecting member that connects a rotating shaft portion that is a rotation center of the spur gear.

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

[0004]

In the panel screen having the above structure, a considerable stress is applied to each gear when the single panel is moved, so that the gears are required to have high strength. For this reason, for this spur gear, for example, a die-cast gear is used, but the tooth shape is not uniform,
Or, in the case of distortion, when it is turned, it may make a clicking sound. Normally, this spur gear has its teeth exposed on the side of the single panel, and its appearance is not very good. With a relatively short single panel, fingers etc. can be caught in the meshing part There was a problem in terms of safety.

[0005] An object of the present invention is to solve such a problem.

[0006]

In order to achieve the above object, the present invention takes the following measures. That is, the panel screen according to the present invention is a panel screen in which at least two single panels movable on the floor are rotatably connected to each other by a connecting means at a side edge of each single panel. The means includes a horizontal cross-axis gear element that is non-rotatably mounted with the longitudinal axis of the side edge of each unit panel aligned with the center axis, and a horizontal meshing gear element on the side of the adjacent horizontal cross-axis gear element and its adjacent part. A vertical cross shaft gear element having a rotating shaft held in the direction and having teeth on both front and rear sides, rotatably supporting the central axis of the horizontal cross shaft gear element, and rotating the rotating shaft of the vertical cross shaft gear element Ri capable Na and and a shaft support member for supporting the shaft support member is, the two horizontal cross shaft gear element
Cover the vicinity of the upper surface of the vertical shaft gear element
To have characterized the Rukoto.

The horizontal cross shaft gear element and the vertical cross shaft gear element in the present invention are preferably formed of a bevel gear such as a straight bevel gear, a helical bevel gear or the like having an axis angle of 90 °.

[0008]

With such a construction, when one of the single panels is rotated, the horizontal cross-axis gear element attached to the single panel and the horizontal cross-axis gear element attached to the other single panel are rotated. Means that they are in mesh with the vertical cross-shaft gear element, so that their mutual rotational position is regulated by their teeth. That is, the angle formed by the two unit panels after the rotation is uniquely determined by the number of meshing teeth of the respective horizontal cross-axis gear elements and the vertical cross-axis gear elements after the rotation is started. The individual panels do not shift unless the gears are disengaged or run idle due to chipping of one of the gears. Therefore, by turning the single panel, it is possible to easily change to a desired form. Further, the meshing portion between the horizontal cross shaft gear and the vertical cross shaft gear is not only close to the center of the side edge of the single panel, but also the shaft support member is required to have both horizontal cross shaft gears.
A finger or the like is placed at the meshing position of the gear element to cover the vicinity of the upper surface of the element.
It is difficult to reach and fingers etc. can be caught in the meshing part
And the safety is improved. In addition, the appearance is also axis
The support member makes it difficult to see the gear elements,
Is improved .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. The panel screen shown in FIG. 1 is configured such that three single panels 1 are rotatably connected to each other by connecting means 2. The single panel 1 includes a rectangular flat panel 11, a frame 12 composed of a vertical frame 12a for supporting the panel 11 from the periphery thereof and upper and lower horizontal frames (not shown), and a lower edge of the lower horizontal frame of the frame 12. The stand 13 is fixed in such a manner as to protrude in the lateral direction thereof and substantially serves as a leg of the single panel 1, and the casters 14 are attached to both ends of the stand 13. The single panel 1 itself may have a structure widely known in this field. Then, the upper end 1 of the left and right vertical frame 12a of the frame 12
The connecting means 2 is attached near 2u and the lower end 12l. An edge member 12b is attached to the frame 12, and its surface is covered.

The connecting means 2 comprises a large-diameter horizontal bevel gear 3 which is a horizontal cross-shaft gear element, a small-diameter vertical bevel gear body 4 which is a gear element having a vertical cross-shaft, and a shaft supporting member 5. Is attached to the vicinity of the upper end 12u and the lower end 12l of the vertical frame 12a of the frame 12 forming the side edge of the frame 12. The horizontal bevel gear 3 has a diameter substantially smaller than the cross section of the vertical frame 12a, and is non-rotatably attached to the vertical frame 12a with its teeth up. At the center of the horizontal bevel gear 3, a shaft hole 31 through which the center shaft 7 is inserted is formed so as to coincide with the center of the vertical frame 12a. In addition, the vertical bevel gear body 4 is formed by two bevel gears 41 having a smaller diameter than the horizontal bevel gear 3 being back-to-back with their respective teeth outside.
A rotating shaft 42 is fixed through the center of the bevel gear 41. The rotation shaft 42 is rotatably attached by the shaft support member 5. The shaft supporting member 5 has a shape in which two cylinders having substantially the same diameter as the horizontal bevel gear 3 are integrally formed, and a through hole 51 that penetrates the center shaft 7 is formed in a center portion of the cylinder. In addition, a concave portion 52 that supports the vertical bevel gear body 4 so as to hide the vertical bevel gear body 4 is provided in a lower portion of a connection portion between the cylinders.

In order to assemble the panel screen with the connecting means 2, the connecting means 2 is attached to the vertical frame 12 a of the frame 12, which is the side edge of each single panel 1, using the mounting bracket 8 made of an angle member. Then, each single panel 1 is rotatably connected. That is, the assembly
For example, first, the mounting bracket 8 is fixed to a predetermined location of the vertical frame 12a of the left and center unit panels 1 facing each other, and the shaft hole 31 into which the central shaft 7 is inserted is aligned with the through hole. The horizontal bevel gear 3 is non-rotatably mounted. Thereafter, the respective unit panels 1, 1 are brought closer to each other until the distance between the shaft holes 31 of the attached horizontal bevel gears 3 matches the distance between the through holes 51 of the shaft support member 5. . Then, the shaft supporting member 5 is placed on the horizontal bevel gear 3, and the upper mounting bracket 8 is placed at a predetermined position thereon, and then the center shaft 7 is inserted into the through-hole 51, and is pushed downward to lower it. The left unit panel 1 and the center unit panel 1 are connected to each other by the shaft supporting member 5 and the center shaft 7 through the through hole of the mounting bracket 8 on the side.

In the panel screen assembled as described above, one horizontal bevel gear 3 of the connecting means 2 can make a half circle around the other horizontal bevel gear 3. For example, the single panel 1 on the left is moved from the front side to the rear side of the central single panel 1. When the single panel 1 is rotated to change the position, for example, the central single panel 1
Is stopped, and the left single panel 1 is rotated,
Since the horizontal bevel gear 3 cannot rotate with respect to the single panel 1, the vertical bevel gear body 4 rotates according to the rotation angle.
As a result, the horizontal bevel gear 3 of the left single panel 1 moves around the horizontal bevel gear 3 of the central single panel 1, and the position of the left single panel 1 is changed.
At this time, each horizontal bevel gear 3 and vertical bevel gear body 4
, The angle formed by the two single panels 1 changes continuously. Moreover, due to the meshing, for example, the positional deviation of the rotating single panel 1 such that the angle formed by the two single panels 1 does not change and only the mutual positional relationship of the single panels 1 changes. Does not occur.

As described above, the connecting means 2 includes the single panel 1
Are disposed in the vicinity of the upper end and the lower end of the unit panel 1 to restrict the displacement of each unit panel 1 during rotation, so that each unit panel 1 is not rotatably connected at its central portion in the vertical direction. In both cases, there is no shift to a position where the front surface of the central unit panel 1 and the back surface of the left unit panel 1 are flush. Further, since the connecting means 2 regulates the displacement of the single panel 1 during rotation by meshing between the horizontal bevel gear 3 and the vertical bevel gear body 4, the rotation is smooth, quiet, and smooth. The position of the single panel 1 can be changed.

If the outer diameter of the horizontal bevel gear 3 is made slightly smaller than the outer dimension of the shaft support member 5 and the lower edge portion of the shaft support member 5 is extended to a position where it comes into contact with the lower mounting bracket 8, The horizontal bevel gear 3 can be covered with the shaft support member 5. In this way, the horizontal bevel gear 3 is completely invisible from the outside, and the only portion of the connecting means 2 exposed to the outside is the shaft supporting member 5. That is, in such a connecting means 2, the mechanical structure is not visible from the outside at all, and the appearance of the shaft support member 5 is made substantially coincident with the edge member 12b, so that the user is conscious of the mechanical connecting means 2. A panel screen having an appearance that does not occur can be obtained. In addition, there is no dangerous structure for the user, such as pinching a finger because such a mechanism is not exposed, and safety can be further improved.

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

[0016]

According to the present invention, as described in detail above, the connecting means for rotatably connecting the single panel has a horizontal cross shaft gear element and a vertical cross shaft gear element which mesh with each other. When one of the single panels is rotated, the rotation is restricted by the meshing of the respective gear elements, and the displacement of the single panel during rotation can be prevented. In addition, the meshing portion between the horizontal cross shaft gear and the vertical cross shaft gear is not only close to the center of the side edge of the single panel , but also the shaft support member is
To cover the vicinity of the upper surface of both horizontal cross axis gear elements, the gear element
It is difficult for a finger or the like to reach the meshing position of
The possibility of being caught is reduced, and safety is improved.
In addition, the gear element is difficult to see due to the shaft support member in appearance.
Therefore, the appearance becomes good .
