By the way, since such a slide window is always in contact with the run channel and the center sash, friction is applied by the run channel and the center sash when the slide window slides. Therefore, the slide window can be kept in a half-open state even when it receives some vibration.

However, for example, when traveling on a rough road with a crawler, etc., or when performing rock drilling work with a rock drilling machine attached to the arm of construction machinery, the slide window will also be subjected to large vibrations, so the half-open position should be avoided. It was difficult to maintain.

Although not shown in the drawings, a conventional sliding window for construction machinery is provided with a bolt with a rubber attached to the tip to maintain the half-open state. There is something to push. However, the bolt must be screwed in after the sliding window has been moved to a predetermined position, resulting in poor operability.

Further, there is also known one in which a plurality of grooves that are open at the top are provided in a lower frame that supports the slide window, and a lock mechanism that engages with the grooves is attached to the slide window. However, the position where the half-open state of the slide window can be maintained is limited to the portion provided with the groove. Also, even if the number of grooves is increased, the processing cost increases as the number increases, and there is also concern about the strength. Furthermore, since the height of the cut-off wall is lowered by forming the groove, there is also a problem in that rainwater tends to enter the room when it rains.

An object of the present invention is to solve such problems, and the slide window for construction machinery can be fully closed or fully opened even when large vibrations occur during work or movement. To provide a slide window holding device which can be held and can be left in a half-open state at an arbitrary position.

The present invention relates to a slide window holding device for holding a slide window for construction machinery at an arbitrary position, wherein the side surface of a frame that slidably supports the slide window along the slide direction of the slide window is provided. A main body provided with an engaging band provided on the outer surface and having uneven portions repeatedly formed in the sliding direction, a base attached to the inner surface of the slide window, and a vertical wall projecting vertically from the base. a lever, a lever rotatably provided on the main lever, and an inclined wall, wherein the inclined wall is tilted toward the slide window and tilted with respect to the vertical wall ; a release lever that is rotatable between an unlocked posture away from the slide window and approaches the vertical wall ; and a stopper that separates from the uneven portion in an unlocked posture.

It is preferable that such a slide window holding device further includes an elastic body that biases the release lever toward the locking position.

Moreover, it is preferable that the stopper has an uneven portion corresponding to the uneven portion.

It is preferable that the frame body has a lower frame that supports the sliding window in a horizontally slidable manner, and that the engaging band is provided on a side surface of the lower frame.

In the sliding window holding device of the present invention, the stopper engages with the concave and convex portion of the engaging band even when the sliding window is slid to any position. A half-open state can be maintained. In order to displace the release lever from the locking posture to the unlocking posture, the slide window can be easily slid to another position because it is sufficient to grasp the release lever together with the main lever. In addition, since the grooves used in conventional structures are not provided, rainwater does not easily enter during rainy weather.
