Description

[Detailed description of the invention] [Technical field] The present invention relates to a height adjustment device for a running body such as a runner that is mounted on a rail so that it can run freely. Regarding the technology to be used.

[Background technology]

Conventionally, a height adjustment device for a running body such as a runner that is mounted on a rail so that it can run freely is adjusted by screwing the runner shaft that holds the running body into the inside of the upper end of the partition body, and changing the screwing amount. The height of the running body is adjusted, and the rotation of the runner shaft after the height adjustment is locked by pressing a lock nut screwed onto the runner shaft against the upper end surface of the partition body. Ta. By the way, in such a configuration, in order to adjust the height of the running body, in addition to rotating the runner shaft, two steps are usually required.
There was a problem in that it was necessary to loosen and tighten the lock nuts used individually, making it troublesome to adjust the height of the traveling implement.

[Purpose of invention]

The present invention was created in view of these problems, and its purpose is to prevent the runner shaft from rotating while being able to prevent the runner shaft from rotating without using a troublesome lock nut. To provide a height adjusting device for a running body of a partition body, which can easily and easily adjust the height of the running body.

[Disclosure of invention]

The height adjusting device for a running body of a partition body of the present invention is a height adjusting device for a running body 2 such as a runner mounted on a rail 1 so as to be freely movable, and the running body 2 is held at the upper end. and a runner shaft 3 which is screwed onto the upper end of the partition body 4 so as to be able to rise and fall to adjust the height position of the traveling body 2 with respect to the partition body 4;
A non-circular rotary operation part 5 that is a protruding part of the runner shaft 3 from the partition body 4 and is fixed at a position lower than the running body 2 and rotates together with the runner shaft 3.
The partition body 4 is held at the upper end of the partition body 4 so as to be movable and non-rotatable, and in the upper position engages with the rotation operation part 5 to prevent rotation of the rotation operation part 5, and in the lower position it is engaged with the rotation operation part 5. The rotation stopper 6 is provided with a rotation stopper 6 that releases the rotation operation part 5 to allow rotation, and a spring 7 that biases the rotation stopper 6 toward the upper position. The device is characterized by comprising a lowering operation section 8 that is operated to move the device to the desired position, and by configuring it in this manner, the above object is achieved. In other words, the rotation stopper 6 can be easily removed from the rotation operation part 5 of the runner shaft 3 by placing a finger or the like on the lowering operation part 8 of the rotation stopper 6 and pushing it down to the lower position against the spring 7. After adjusting the height of the running body 2 by rotating the runner shaft 3 via the rotary operation part 5, by removing the finger from the lowering operation part 8, the rotation stopper 6 is stopped by the spring 7. can be raised to the upper position and engaged with the rotation operation part 5 to lock the rotation of the runner shaft 3, thus making it possible to easily and easily adjust the height of the running body 2.

Then, the cylindrical body 22 of the cover 13 is inserted into the aluminum core material 12, and the screws inserted through the through holes of the cover 13 are screwed into the tapping holes 24 of the hinge 11 to attach the cover 13. By screwing the threaded portion 16 of the runner shaft 3 into the runner 23 and rotating the rotary operation section 5, the runner shaft 3 can be raised and lowered.

As shown in FIG. 3, the rotation stopper 6 is approximately L-shaped, and has a through hole 26 formed in its upper horizontal piece 25, through which the runner shaft 3 is inserted. A cylindrical body 27 is protruded from the peripheral edge of the through hole 26 so that the rotation stopper 6 can be smoothly moved up and down on the runner shaft 3. A pair of upright pieces 28 , 28 are protruded from both sides of the upper horizontal piece 25 , and these upright pieces 28 , 28 sandwich both sides of the hexagonal nut-shaped rotary operation unit 5 . It is designed to be able to stop the rotation. The vertical piece 29 of the rotation stopper 6 is inserted into a groove 30 formed in the core material 12 made of aluminum. Then, the spring 7 in the form of a coil spring inserted into the runner shaft 3 is attached to the cover 13.
and the upper horizontal piece 25, and the rotation stopper 6 is elastically biased by a spring 7 so that it engages with the rotation operation part 5. Aluminum core material 12
A synthetic resin cover piece 31 is inserted into the groove 30 to cover the core material 12.

According to such a configuration, the rotation stopper 6 is pushed down to the lower position against the spring 7 by placing a finger on the lowering operation part 8 at the base end of the upper horizontal piece 25, and the rotation operation part of the runner shaft 3 is pressed down. 5, and engage a tool such as a wrench with the rotary operation section 5 to rotate the rotation operation section 5. The runner shaft 3 is raised and lowered by screw rotation, and the running body 2 is moved to a predetermined height. Adjust accordingly. After adjusting the height of the running body 2 by rotating the runner shaft 3 in this way, when you remove your finger from the lowering operation part 8, the spring 7 springs the rotation stopper 6 and raises it to the upper position. The runner shaft 3 is then engaged with the lowering operation portion 8 to lock the rotation of the runner shaft 3.

In the embodiment, the traveling body 2 is provided at the pivot connection point, but the mounting position thereof can be changed in various ways, such as being directly attached to the upper end of the partition body 4.

8 to 11 show another embodiment, in which the vertical piece 29 of the rotation stopper 6 is inserted into the notch 3 of the upper cover 13.
3, and is inserted into the holder so that it can be raised and lowered freely. That is, the runner shaft 3 is inserted through a runner block 19 having runner rollers 21 on the horizontal shaft 20, and the washer 3
4, the runner shaft 3 is prevented from coming off in the middle part thereof, and the rotary operation part 5 detailed in the embodiment shown in FIGS. A notch 33 as shown in the figure is formed. The rotation stopper 6 has a structure shown in FIGS. 3 and 4, in which a cylinder body 27 is suspended from a through hole 26 formed in the upper horizontal piece 25, and a pair of upright pieces are provided on the upper horizontal piece 25. 28 is formed. Therefore, the through hole 2 is inserted into the runner shaft 3.
