Claims

[Scope of utility model registration request]

Roll Screen A roll that stops the raw cloth at a desired height by stopping a raw cloth winding cylinder equipped with a torsion spring that always acts in the direction of winding up the raw cloth at a desired position against the force of the torsion spring. In the screen lifting/lowering stop device, a guide wheel is fixed coaxially to one end of the raw cloth winding cylinder, and a bearing part that supports the end of the raw cloth winding cylinder is mounted so as to face the guide wheel. A switching wheel is fixed, a pawl movable in the radial and axial directions is pivotally supported on the surface of the switching wheel facing the guide wheel, and the pawl is always pushed in the axial direction toward the guide wheel. At the same time, a spring is provided to push the pawl outward in the radial direction, and the surface of the guide wheel facing the switching wheel has a coaxial outer circumferential groove and an inner circumferential groove for receiving the pawl that is constantly pushed in the axial direction. In addition to providing a groove, an entry groove is also provided for introducing the pawl from the outer groove to the inner groove when the guide wheel rotates in the direction of pulling down the raw cloth. A step portion is formed that guides the pawl into the entry groove against the force of a spring that pushes the pawl outward in the radial direction only when the guide wheel rotates in the pull-down direction; A step part is formed at the connecting part of the groove to allow the pawl to enter the inner circumferential groove from the entry groove, but to prevent it from returning from the inner circumferential groove to the entry groove. An outlet groove is formed on the surface of the opposing guide wheel to guide the pawl that is pushed outward in the radial direction by the spring when the guide wheel rotates in the direction of pulling up the raw cloth, and a mold cylinder is formed at the end of the outlet groove. A roll characterized in that a resting part is formed, and an escape groove is formed for causing the pawl to escape from the mold resting part to the outer circumferential groove when the guide wheel rotates again in the direction of pulling down the raw cloth. Screen lifting/lowering stop device.
