Description

[Detailed description of the invention] [Technical field] The present invention includes a partition panel that is built in such a way that it can run freely along the upper rail, and also that the lower end of the partition panel is in contact with the floor surface so that there is a gap between the partition panel and the floor surface. The present invention relates to a partition device in which a floor contacting member that closes a gap is provided so as to be movable up and down.

[Background Art] Conventionally, a partition panel is installed so that it can run freely along an upper rail, and a floor contacting member is provided at the bottom end of the partition panel to contact the floor surface and close the gap between the partition panel and the floor surface. In a partition device that is provided so that it can be raised and lowered, there is a problem in that a large operating force is required, especially to raise the floor-contacting member.

[Purpose of the invention] The present invention was made in view of these problems, and its purpose is to provide a partitioning device that can reduce the operating force for raising and lowering the floor-contacting member. .

[Disclosure of the invention] In the present invention, the partition panel 2 is installed so as to be able to freely run along the upper rail 1, and the lower end of the partition panel 2 is brought into contact with the floor surface to close the gap between the partition panel 2 and the floor surface. In a partition device in which a closing floor contacting member 3 is movably raised and lowered, a pinion gear 14 that is rotatably operated by an operation from an operation part 6 is provided at the lower part of the partition panel 2, and a large-diameter gear 15 and a pinion gear 14 are provided in the lower part of the partition panel 2. A small diameter gear 16 is formed, and a vertical frame 17 is erected from the flooring member 3.
A rack gear portion 18 is formed on the vertical frame 17,
A rack gear 20 is formed on an intermediate member 19 operated by an operating part 6, and the rack gear 20 is engaged with a large diameter gear 15 of a pinion gear 14, and the rack gear portion 19 is engaged with a small diameter gear 16. By configuring the device in this way, the above object can be achieved. That is, the rack gear 20 of the intermediate member 19 operated by the operating part 6 is engaged with the large diameter gear 15 of the pinion gear 14, and the small diameter gear 16 of the pinion gear 14 is engaged with the rack gear portion 18 of the vertical frame 17 on the floor contacting member 3 side. By meshing, the floor contact member 3
The operating force for lifting and lowering is reduced.

Embodiments of the present invention will be described in detail below based on the drawings.

As shown in FIG. 4, the partition panel 2 is built into the upper rail 1 so that it can run freely through runner rollers 7 that are rotatably attached to the upper end of the partition panel 2.
As shown in FIGS. 2 and 3, the partition panel 2 can be released from the partition state to the partition release state. The partition panel 2 is constructed by attaching a face plate 11 to a panel frame 4 formed in a substantially square shape. A hollow concave vertical frame 9 is attached to one end in the width direction of the panel frame 4, and a convex vertical frame 10 that can be fitted in concave and convex to the concave vertical frame 9 is attached to the other end. An elevating frame 8 is provided in the frame 8 so that it can only be moved up and down. A flooring body 12 made of soft rubber is attached to the lifting frame 8. An operating wire 5 and an operating force reducing means 13 operated by the operating wire 5 are interposed between the elevating frame 8 and an operating section 6 provided on the side surface of the partition panel 2. The floor body 12 can be lowered to close the gap between the partition panel 2 and the floor using the floor body 12, and the floor body 12 can be raised with a light force. There is. The elevating frame 8 and the ground contacting body 12 are collectively referred to as the floor contact member 3, but the configuration thereof can be modified in various ways. The elevating structure of the floor contacting member 3 will be explained below.

A support frame 21 is installed at the lower end of the partition panel 2, and between the support frame 21 and the panel frame 4, an intermediate member 19 is provided so as to be movable in a substantially horizontal direction. Convex vertical frame 10
An operating wire 5 is inserted into the interior of the frame 10, and the operating wire 5 is turned approximately horizontally by a guide 22 at the lower end of the convex vertical frame 10, and the tip of the operating wire 5 in the approximately horizontal direction is It is attached to the intermediate member 19. The upper end of the operating wire 5 is attached to the operating section 6. Thus, by operating the operating section 6, the intermediate member 19 can be operated in the horizontal direction. The casing 2 is attached to the support frame 21.
3 is attached to the casing 23, and a pinion gear 14 is rotatably provided on this casing 23. The pinion gear 14 is provided with a large diameter gear 15 on its outer periphery, and a rack gear 20 formed on the intermediate member 19 is meshed with this large diameter gear 15.
By moving the pinion gear 14, the pinion gear 14 can be rotated. A small diameter gear 16 is formed on the pinion gear 14, and this small diameter gear 1
6 is meshed with a rack gear portion 18 formed on a vertical frame 17 erected on the elevating frame 8, so that the elevating frame 8 can be raised and lowered by rotation of the pinion gear 14. Support frame 2
A spring 24 is interposed between the lifting frame 8 and the lifting frame 8, and the lifting frame 8 is biased to protrude downward. This force allows it to make strong contact with the floor.

According to such a configuration, the spring 24 is pulled up by the pulling operation of the operating wire 5 by the operating section 6.
However, in this case, the intermediate member 19 is meshed with the large diameter gear 15 of the pinion gear 14, and the amount of operation is large, but the floor contact member 3 is raised with a small force. It is possible to raise the amount of

6 and 7 show the structure of the operating section 6. FIG. Convex vertical frame 10 on one side of the partition panel 2
A handle shaft 26 is rotatably provided on a case 25 that is attached to the case 25. A pinion gear member 27 is integrally provided on the handle shaft 26, and this pinion gear member 27 is meshed with a rack gear portion 29 formed on a lifting member 28 provided on the case 25 so as to be able to rise and fall freely. This allows the elevating member 28 to be raised and lowered. The other end of the operating wire 5 is attached to the elevating member 28. A crank-shaped operating handle 30 is provided on the handle shaft 26 so as to be engageable and detachable.

A ratchet gear 31 is integrally provided on the handle shaft 26, and a ratchet pawl 32 is provided on the case 25 and is biased to rotate toward the ratchet gear 31 by a spring 34. Thus, by rotating the operating handle 30 in the winding direction of the operating wire 5, the non-floor state in which the floor-contacting member 3 is raised from the floor surface can be maintained even if the operating handle 30 is released. There is. The casing 25 has a release button 33
is provided so as to be freely pushable and operable against the spring body 37. The release button 33 is formed with a tapered surface 35, and when the release button 33 is pressed, the ratchet pawl 32 is pushed against the spring 34 by the tapered surface 35.
is rotated around its pivot pin 36 to allow reverse rotation of the ratchet gear 31.

According to such a configuration, by engaging the operating handle 30 with the handle shaft 26 and rotating it, the operating wire 5 is pulled up and the floor contacting member 3 is raised against the spring 24. By setting the device to the non-floor contact state and pressing the release button 33, the ratchet pawl 32 is released from the ratchet gear 31, and the spring force of the spring 24 lowers the floor contact member 3 and attaches it to the floor surface.
This closes the gap between the partition panel 2 and the floor.

[Effects of the invention] In summary, the present invention meshes the rack gear of the intermediate member operated by the operating section with the large diameter gear of the pinion gear, and meshes the small diameter gear of the pinion gear with the rack gear portion of the vertical frame on the floor contacting member side. By doing so, there is an advantage that the force for lifting and lowering the portion in contact with the floor can be reduced.
