[Embodiment] An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a traveling stop device according to the present invention, which comprises a guide body 1 and a traveling body 2.
It is composed of a steel ball 3, a restraining body 4, a pressing means 5, a spring 6, a variable quantity means 7 and a force changing means 8, and as shown in FIG. It is attached to a vertical sliding window 9 that can be opened and closed by operation.

Reference numeral 10 in the drawing is a spring for retracting the traveling body 2 to the original position.

The guide body 1 is for guiding the traveling operation of the traveling body 2, and in this embodiment, is formed of a substantially cylindrical case having an opening portion opened to the tip side, and the base end side is a window. It is rotatably attached to the frame 9a side. And
A female screw 1 a is cut on the tip opening side of the guide body 1.

The traveling body 2 linearly moves within a certain range while being guided by the guide body 1, and in this embodiment, the piston 11 that slides in the guide body 1, which is a case, and the piston 11 on the base end side. It is composed of a mounted piston rod 12. And this piston rod 12
Is formed in a substantially columnar shape, has a fitting groove 12a formed at a predetermined position on the intermediate portion side, and has a tip end side rotatably attached to the window 9 side.

When the piston rod 12 of the traveling body 2 slides forward to a predetermined position, the steel ball 3 moves there.
It is to be fitted into the fitting groove 12a of FIG. 2 and to stop the traveling operation of the running body 2 by this, and in this embodiment, as shown in FIG. 3, it is pressed against the outer peripheral surface of the piston rod 12 and rolls. It consists of four items.

The restraint body 4 is formed in a substantially cylindrical shape having an insertion hole 4a at the center side, and for restraining the steel ball 3, the steel ball 3 is provided along the radial direction between the outer peripheral surface side and the insertion hole 4a. Four restraining holes 4b are formed in conformity with the outer diameter of the piston rod 12 so that they can freely slide on the outer peripheral surface of the piston rod 12 inserted into the inserting holes 4a.

The pressing means 5 is for fitting the steel ball 3 into the fitting groove 12a by the elastic force of the spring 6 while pressing the protruding portion of the steel ball 3 protruding from the restraining body 4 from the outside. In the example, it is composed of a fixed cylinder 13 and a sliding cylinder 14. The fixed cylinder 13 is for preventing the restraint body 4 from moving toward the base end side in the guide body 1, and the opening portion 13 into which the base end side of the restraint body 4 enters the tip end side.
It is formed in a substantially U-shaped cross-section having an insertion hole 13b through which the piston rod 11 on the traveling body 2 side is slidably inserted at the center side and is screwed to the guide body 1 side. . The fixed cylinder 13 has the opening 13
Tapered surface 1 whose a-side end surface is formed in a taper shape toward the inside
3 c, the tapered surface 13 c is locked to the projecting portion of the steel ball 3, and the steel ball 3 is prevented from coming out of the restraining hole 4 b of the restraining body 4. The sliding cylinder 14 is slidably arranged in the guide body 1, the distal end side of the restraining body 4 is inserted thereinto, and the piston rod on the traveling body 2 side is allowed to freely slide on the central portion side so that the central portion side is slidable. Is formed in a substantially ring shape having a large insertion hole 14a, and the base end side end surface has a tapered surface 14 similar to that of the fixed cylinder 13 described above.
b is formed.

The spring 6 urges an elastic force to the steel ball 3 side via the sliding cylinder 14 on the pressing means 5 side, and the steel ball 3 is pushed to the piston rod 1
This is for pressing the steel ball 3 into the fitting groove 2a while pressing the steel ball 3 into the fitting groove 2a. When the steel ball 3 is fitted into the fitting groove 12a of the piston rod 12, the piston 8 is not pulled back by the spring 8 and is not separated from the fitting groove 12a so that a stable fitting state can be maintained. Depth of 13c, tapered surfaces 13c, 14b
The tilt angle of is set.

The variable means 7 is for changing the relative position between the fitting groove 12a of the traveling body 2 and the steel ball 3 to change / adjust the movement stop position of the traveling body 2, and in this embodiment, the guide body 1 of the guide body 1 is used. It is adapted to be screwed into the opening. The variable means 7 engages with the fixed cylinder 13 from the rear side and regulates the movement of the steel ball 3 so that the steel ball 3 does not move rearward through the fixed cylinder 13. The position of the sphere 3 is set and held constant by the regulation from both directions including the regulation from the front side of the ball 3. Therefore, this variable means 7
By rotating this to change the screwing position with respect to the guide body 1, the movement stop position and the movement amount of the traveling body 2 can be easily changed and adjusted.

The variable means is not particularly limited to this embodiment, and for example, a piston and a piston rod may be screwed together, and the screwing positions of both of them may be changed. .

The force changing means 8 is for adjusting / changing the pressing force of the spring 6 on the pressing means 5 side, and for adjusting the fixed holding force of the traveling body 2 when the traveling body 2 stops traveling. In this embodiment, It is adapted to be screwed into the opening on the side of the variable means 7. By rotating the variable amount means 7 to change the screwing position with respect to the variable amount means 7 side, the fixed holding force for the traveling body 2 side can be changed easily and highly accurately when the traveling body 2 is stopped. It is like this.

Next, the operation of the travel stopping device of this embodiment will be described.

First, for example, when the window 8 is pushed out by hand and opened as shown in FIG. 2, the traveling body 2 side advances with respect to the guide body 1 side (see FIG. 1).

Then, when the window 8 is opened to a predetermined angle, the fitting groove 12a provided in the piston rod 12 on the traveling body 2 side is advanced to the position of the steel ball 3 and is pressed by the spring 6 via the pressing means 5. The steel ball 3 enters the fitting groove 12a (see FIG. 4).

At this time, as shown in FIG. 5, the elastic force of the spring 6 causes a strong elastic force to the left in the guide body 1 from the sliding cylinder 14 to the steel ball 3 into the fitting groove 12a.
Since a strong pressure contact force toward the direction is applied, the piston rod 12 is not retracted by the spring 8 and is securely fixed and held at the stop position.

〔effect〕

As described above, according to the travel stopping device of the present invention, the steel ball fitted into the fitting groove formed on the traveling body side, the restraining body restraining the steel ball to the outer surface side of the traveling body, and the restraining body. A pressing means for pressing the steel ball restrained by the body toward the outer surface of the traveling body by a spring, a force changing means for adjusting and changing the elastic force of the spring urging the pressing body, and a fitting groove for the traveling body. It is composed of variable means for changing and adjusting the movement stop position of the running body by changing the relative position with the steel ball.In other words, it is composed of a simple mechanism with a relatively small number of parts, and is simple. The fixed holding force and the moving amount (moving stop position) of the traveling body can be changed and adjusted by the operation, and the device can be downsized and the manufacturing cost can be reduced.
