Description

[Detailed Description of the Invention] Technical Field This invention relates to a floor contacting device for a partition door that appropriately demarcates an indoor space.

Conventional technology Generally, partition doors are movably suspended along guide rails fixed to the ceiling, and when in use, a gap remains between the partition door and the floor, resulting in poor airtightness for sound insulation and heat retention. It was inferior. Therefore, a floor contacting device that can move up and down relative to the panel is provided at the lower end of each panel of the partition door to close the gap between the panel and the floor.

However, since the vertical movement stroke of this floor contacting device is constant, it has the disadvantage that it cannot adequately respond to changes in the clearance at various installation locations of the partition door.

Purpose This invention was made in order to overcome the drawbacks of the conventional flooring device as described above, and its purpose is to create a partition that can accommodate various gaps between each panel of the partition door and the floor. To provide door flooring device.

Embodiment An embodiment embodying this invention will be described below with reference to the drawings. 1 is a partition door suspended from a rail 3 fixed to a ceiling 2, and a runner 4 runs along the rail 3. Each panel 5 is movably suspended from the other.

Reference numeral 6 denotes a flooring device attached to the lower end of each panel 5. This flooring device will be explained in detail with reference to FIGS. 2 to 5. 7 is a vertical stile that forms the side edge of the panel 5, and 8 is a connection support between the vertical stile 7 at a slightly lower part of the center of the panel 5. This horizontal frame 8 is not filled with a core material. Reference numeral 9 is a hanging shaft whose upper end is fixed to the horizontal frame 8, and the lower end of which is rotatably supported by the shaft 11 at the center of an actuating body 10 consisting of a pair of long plates.

Reference numeral 12 denotes a lever support body screwed onto the lower outer surface of one vertical stile 7, and a through hole 13 is provided in the vertical stile 7 corresponding to the center portion of the support body 12. 1
Reference numeral 4 denotes a primary drive shaft that is vertically movably inserted through annular support members 15 that are vertically formed on the back surface of the lever support body 12, that is, inside the panel 5, and that is inserted into the annular support members 15, and its upper end is connected to the actuating body 10. A shaft 16 is rotatably supported at one end. Reference numeral 17 denotes an operation lever whose base end is rotatably supported on the lever support 12, and whose base end is connected to the primary drive shaft 1.
The primary drive shaft 14 can be driven up and down by rotating the operating lever 17 up and down. Further, a groove (not shown) is formed in the lever support 12 so that the operating lever 17 can be housed in parallel with the support 12, and the lever 17 is always urged upward or downward to fill the groove. A biasing means (not shown) is provided for housing therein.

18 is a secondary drive shaft connected to the other end of the actuating body 10, and has a long hole 20 provided in the axial direction at the upper end.
A pin 19 supported at the other end of the actuating body 10 is movably inserted into the pin 19, and the secondary drive shaft 18 is slidable vertically with respect to the actuating body 10, and its lower end is connected to the lower end of the panel 5. It passes through a through hole 21a provided in a horizontal stile 21 that constitutes the. This pin 19 also has a cylindrical upper spring receiver 2.
3a is rotatably supported with the secondary drive shaft 18 inserted therethrough.

Reference numerals 22 denote a lower spring receiver 23b fixed to the center of the secondary drive shaft 18 and the upper spring receiver 23.
The coil spring is disposed such that the secondary drive shaft 18 is inserted between the coil spring and the actuator 10, and biases the secondary drive shaft 18 downward with respect to the actuating body 10.

Reference numeral 24 denotes a floor stile that is movable up and down within the horizontal stile 21 at the lower edge of the panel 5, and has a length that is approximately the same as the width of the panel 5, and its cross-sectional shape is shown in FIG. A pair of side walls 24b extending upward are formed on both sides of the bottom surface 24a, and a pair of L-shaped fitting pieces 24c are provided at the lower part of the bottom surface. The lower end of the secondary drive shaft 18 is inserted between the side walls 24b at the center of the floor frame 24 and fixed with a pin 25.

26 is a fitting piece 24c at the bottom of the floor frame 24,
The floor cushion is fitted over the entire length of the floor stile 24, and is made of an elastic material such as synthetic rubber.As shown in FIG. The floor cushion 2 is provided with a strip 26a and a through hole 26c in the center of the cross section.
A plurality of cushions 6 are provided above and below the cushion 6 to enhance the elasticity of the cushion 26. Two notches 26b are provided on both sides of the cushion 26, and these notches 26b
If the lower portion is broken off, a protrusion similar to the protrusion 26a will be exposed. In addition,
27 is the floor surface below each panel 5.

Next, the operation of the floor contacting device 6 configured as described above will be explained.

Now, FIG. 2 shows a state in which the floor contacting device for the panel 5 is not activated, and the operating lever 17 is housed in the lever support 12. When the tip of the operating lever 17 is rotated downward from this state, the base end drives the lever receiving portion 14a upward, and the primary drive shaft 14 is moved upward. Then, one end (the left end in FIG. 2) of the actuating body 10 is rotated upward, and at the same time, the other end (the right end) is rotated downward.

When the other end of the operating body 10 is rotated downward, the secondary drive shaft 1 is suspended from the pin 19 at the other end.
8 is moved downward, and the floor cushion 26 comes into contact with the floor surface. At this time, the operating lever 17 is rotated slightly below the horizontal position. From this state, when the operating lever 17 is further rotated downward until it is housed in the lever support 12, the upper spring receiver 2 supported at the other end of the actuating body 10 is moved as shown in FIG.
3a moves downward along the elongated hole 20 of the secondary drive shaft 18 while compressing the coil spring 22 downward.

The coil spring 22 compressed downward presses the lower spring receiver 23b downward. As a result, the secondary drive shaft 18 is pressed downward, and the floor cushion 26 is pressed against the floor surface 27.

In this way, the gap between the lower end of the panel 5 and the floor surface 27 is closed by the flooring frame 24 and the flooring cushion 26, and the flooring cushion 26 is pressed against the flooring surface 27 by the biasing force of the coil spring 22. Therefore, the partition door 1 in which the panels 5 are successively constructed has excellent sound insulation and airtightness.

On the other hand, due to changes in the installation location of the partition door 1, the gap between the floor cushion 26 and the floor has increased to a second level.
If it is significantly smaller than the state shown in the figure, the other end of the operating body 10 must move downward beyond the stroke regulated by the elongated hole 20 of the secondary drive shaft 18 after the floor cushion 26 contacts the floor surface. It becomes a state where
The operating lever 17 cannot be rotated to the position where it is housed in the lever support 12. However, in such a case, by removing the lower part of the floor cushion 26 from the notch 26b and adjusting the height of the floor cushion 26, the operating lever 17 can be pressed while the floor cushion 26 is pressed against the floor surface 27. can be rotated to a position where it is housed in the lever support 12.

Therefore, this floor contact device 6 is connected to the floor contact cushion 26.
It is possible to improve the sound insulation and airtightness of the partition door 1 by pressing it onto the floor surface 27 with the coil spring 22, and to actuate the secondary drive shaft 18 when there is a slight change in the gap between the panel 5 and the floor surface 27. body 10
This can be accommodated by the elongated hole 20 connected to.
In addition, a gap that cannot be accommodated by the elongated hole 20 can be accommodated by breaking off the lower part of the floor cushion 26 from the notch 26b and adjusting the height of the floor cushion 26 as appropriate. Since each cut 26b is formed in the same shape as the protrusion 26a, the shape of the lower part of the cushion does not change before and after the break-off. In addition, the break-off surface is ridge 2.
It is always located above 6a and does not enter the field of vision, and can be reliably brought into contact with the floor by the arcuate surface of the protrusion 26a.

Effects As detailed above, in this invention, the shape of the lower part of the cushion 26 does not change before and after the lower part of the cushion 26 is broken off, and the protrusion 26a located below the breaking surface allows the lower part of the cushion 26 to be cut off from the floor surface. It exhibits an excellent effect of ensuring reliable contact with the floor.
