[Industrial applications]

 The present invention relates to the improvement of the detaching structure of the roll pipe and the screen of the roll blind, and more specifically, it is possible to remove the screen from the roll pipe while the roll pipe is still attached to the roll blind. The present invention relates to a detachable structure to which a screen can be attached.

[0002]

[Prior art]

 A roll pipe having a structure in which a screen can be attached to and detached from a roll pipe that is still attached to a roll blind is known from Japanese Utility Model Publication No. 5-7431. This roll pipe has a fastening groove that extends in the longitudinal direction of the roll pipe on the outer peripheral surface, and one of the synthetic resin needle cloth joining pieces is bonded to the fastening groove, and the synthetic resin needle cloth joining is performed on the upper edge of the screen. This is a method in which the other of the pieces is adhered and both joint pieces are engaged in the fixing groove to fix the screen to the roll pipe.

[0003]

[Problems to be solved by the device]

 When detaching the screen attached to the roll pipe, the worker must separate or join the joining pieces while moving in the longitudinal direction of the roll pipe attached to the roll blind. In the case of the roll bride installed at a high place, it was very troublesome for the worker to move in the longitudinal direction of the roll pipe. Therefore, it has been demanded that the screen can be attached to and detached from the roll pipe as it is attached to the roll blind without the operator having to move in the longitudinal direction of the roll pipe.

The present invention has been made in response to this demand, and its purpose is to install a screen on a roll pipe that is attached to a roll blind even if the operator does not move along the roll pipe. It is intended to provide a screen desorption structure of a roller blind that can be desorbed.

[0005]

[Means for Solving the Problems]

 To achieve the above object, the means adopted by the present invention is to provide a groove portion extending in the longitudinal direction of the roll pipe on the outer peripheral surface of the roll pipe, and disposing a plurality of runners movably in the longitudinal direction of the roll pipe in the groove portion. , The runner is provided with a hook, and the screen is provided with a hook hook that engages with the hook. It is desirable that the hook of the runner be a split shaft-shaped hook or a hook-shaped hook, and a metal or fiber ring-shaped hook hook to be hung on the hook or hook is fixed to the screen.

[0006]

[Action]

 Since the runner can move freely along the groove provided in the roll pipe, when removing the screen from the roll pipe for maintenance, the operator pulls the upper edge of the screen at one position in the longitudinal direction of the roll pipe. , The screen can be easily removed from the roll pipe by simply removing the hook hook fixed to the upper edge of the screen from the runner hook. At this time, the runners gather at one place in the longitudinal direction of the roll pipe.

After the maintenance is completed, the worker can easily roll the screen by hooking the hooks of the runners gathered at one position in the longitudinal direction of the roll pipe on the hook upper end of the screen and pushing the screen to unfold it. Can be attached to the pipe. In this way, since the worker can attach and detach the screen to the roll pipe at one place, even if the roll blind is installed at a high place, the screen can be easily attached and detached with the roll pipe attached to the roll blind. You can

【Example】

 A screen mounting / demounting structure for a roller blind according to the present invention will be described based on an embodiment shown in the drawings. In the first embodiment shown in FIGS. 1 and 2, a groove portion 3 extending in the longitudinal direction is formed on the outer peripheral surface of the roll pipe 1, and a plurality of runners 2 are slidably arranged in the groove portion 3. The void of the groove portion 3 is composed of a deep portion 31, a shallow portion 32, and a narrow portion 33 having a small inner width in the middle thereof in the cross section. The runner 2 includes a disk-shaped base 21 that fits in the deep portion 31, a center 22 that projects from the center of the base to the shallow portion 32 through the narrow portion 33, and a male hook-shaped hook 4 formed at the tip of the center. Consists of. The hook 4 has a larger diameter on the tip side than on the root side, and is opened and closed in the diametrical direction by a diametrical slit 24. A plurality of female hook-shaped hooks 5 are fixed to the upper edge 11 of the screen 10 which is formed thicker. The hook 5 is attached to the hook 4 of the runner 2, the upper edge 11 of the screen 10 is attached to the runner 2, and the screen 10 is attached to the roll pipe 1 via the runner.

Since the runner 2 can be freely moved in the longitudinal direction of the roll pipe 1, when detaching the screen from the roll pipe for washing or the like, the operator can place the screen 10 at one position in the longitudinal direction of the roll pipe. The screen 10 attached to the roll blind can be detached from the roll pipe 1 only by pulling the upper edge portion 11 of the upper part and pulling out the hook hook of the screen 10 from the hook 4 of the runner 2. At this time, the runners 2 gather at one location in the longitudinal direction of the roll pipe 1.

Next, when attaching the washed screen to the roll pipe again, at one place in the longitudinal direction of the roll pipe where the runners gather, the worker puts the hook of the screen on the hook of the runner and attaches the screen. The screen can be attached to the roll pipe simply by unfolding it. In this way, the worker can attach and detach the screen to the roll pipe at one place without moving in the longitudinal direction of the roll pipe, so that even if the roll blind is installed at a high place, the roll pipe can be removed. You can easily attach and detach the screen to the roll pipe without removing it from the roll pipe.

In the second embodiment shown in FIG. 3, the runner 2 is arranged in the groove portion 3 of the roll pipe 1 so as to be movable along the groove portion 3 and to be able to rotate partially. is there. The runner 2 includes a shaft portion 24 extending in the lengthwise direction of the roll pipe, an arm 25 extending from the shaft portion in a direction orthogonal to the lengthwise direction of the roll pipe, and a hook-shaped hook 4 axially attached to the front end of the arm. . The groove portion 3 is composed of a bearing portion 34 that supports the shaft portion 24 of the runner 2 in a cross section so as to be slidable and partially rotatable, and a recess 35 that accommodates the arm 25 of the runner 2 and the hook 4. A button hole is formed in the upper edge portion 11 of the screen 10 as a hook hook, and the button hole is hooked on the hook 4 of the runner 2 or a ring is fixed, and the hook 4 is hooked on the ring and the screen 10 is attached. It is attached to the roll pipe via the runner 2.

In the second embodiment, as shown in FIGS. 4 (a) and 4 (b), when the groove portion 3 of the roll pipe 1 is lowered when the screen 10 is attached / detached, the shaft portion 24 of the runner 2 is rotated. Since the arm 25 and the hook 4 hang down from the roll pipe 1, the hook hook 5 of the upper edge portion 11 of the screen 10 can be hooked on the hook 4 of the runner 2, and vice versa. It is extremely easy to combine the edge portions 11 in one place and to deploy them in reverse.

[Effect of device]

 As described above, the screen attachment / detachment structure of the present invention differs from the conventional one in that the screen is attached / detached to / from the roll pipe through the runner that is movable in the length direction of the roll pipe. The screen can be attached to and detached from the roll pipe at one place without moving in the direction, and even if the roll blind is installed at a high place, the screen can be easily rolled without removing the roll pipe from the roll blind. It has an excellent effect that it can be attached to and detached from the blind.
