Description

  The present invention relates to a mesh door and a mesh window with a storage frame that automatically rewinds and opens the net with the elasticity of a spring.

  Conventionally, a screen door or the like is framed by incorporating a net storage frame at one end so that it can be completed when the net is not needed seasonally. In this case, as shown in the drawing of the embodiment, the net storage frame has the connecting blocks 8 and 9 screwed to the upper and lower ends in the face contact, and in the meantime, as the winding device 7 of the net 5, the winding shaft 27, A coil spring 25 for automatically storing a winding force, a central shaft 31 for applying a rotational elastic force to the coil spring 25 with respect to the take-up shaft 27, and the like are provided. The movable rod 12 is attached to the tip of the net 5, and the movable rod 12 is stopped against the elastic force of the coil spring 25 on the other vertical frame 2 so that the net is in a tensioned state.

  Further, when the tension state is released, the net 5 is automatically wound up by the force of the coil spring 25. However, in order for the net tension and storage to be performed normally without excess or deficiency, adjustment is sometimes necessary. Therefore, the main part of the adjusting device 10 is provided at the upper end, which is a structure related to the internal winding device 7, the coil spring 25, and the like.

  Insects and garbage enter the net storage frame through a small gap, and garbage attached to the net will enter at the same time as storage, so the inside will become dirty with insect dead bodies and garbage. That was inevitable.

  In the net storage frame, as described above, the front is the open / close cover 17 because it is necessary to adopt a structure for storing the net and to maintain and maintain the function. However, the structure can be improved by opening the open / close cover. It was complicated and I could not clean the inside cleanly. In particular, in order to remove the dirt adhering to the net, the work can be facilitated by removing the winding shaft 27 of the net. However, as long as the winding shaft 27 is not removed from the upper and lower frames 3 and 4 of the connecting blocks 8 and 9. Because it was a structure that could not be removed, it was actually impossible to remove the net and clean it.

  In view of the above situation, the present invention provides a screen door with a net storage frame that can easily remove the net together with the winding device while maintaining the frame without removing the connecting block of the frame such as the screen door. The problem was to provide a mesh window.

  In order to solve the above-mentioned problems, the present invention has a frame for opening and closing a net by a left and right vertical frame and an upper and lower frame. One of the frames is a net storage frame, and a winding shaft is provided by the elasticity of a coil spring. A net winding device that rotates around the central axis is built in, and an open / close cover is pivotally supported so that the winding device can be removed. In a screen door and a mesh window in which a connecting block is screwed and a winding device adjusting device is provided on one end of the connecting block side, and the central axis of the winding shaft is detachably connected to the adjusting device, both connecting blocks are The inner substrate made of metal or resin is screwed, and the adjusting device is installed between the connecting block and the inner substrate at one end, and the connecting block at the other end is attached to itself or to it. The part is provided with a shaft support hole that becomes the center of rotation of the take-up shaft, a lower bearing is provided at the other end of the take-up shaft, and a movable shaft with a finger hook that goes in and out of the shaft support hole coaxially with the center axis. A screen door and a net window with a net storage frame, characterized in that are provided.

  Since the screen door and the net window with the net storage frame are configured as described above, when removing the net wound around the storage frame, the movable shaft is lifted while lifting up the finger hook protruding on the lower bearing in the state where the opening / closing cover is opened. Pull up the take-up shaft from the lower end by pulling it up from the shaft support hole. If it does so, since the center axis | shaft of a winding apparatus will remove | deviate from the adjustment apparatus in the upper end, the winding apparatus in which the net | winding was wound can be removed with a net | network so that a net | frame storage frame may become empty.

  As described above, according to the screen door and net window with a net storage frame of the present invention, the winding device can be detached from the net storage frame and removed without disassembling the frame. In addition to being able to clean the inside of the net storage frame, there is an excellent effect that it can be completely cleaned by pulling out the net from the winding device while rewinding it.

  Further, when the lower bearing is provided with a coil spring for biasing the movable shaft downward or a seat plate joined to the lower inner substrate is formed (Claim 2), the lower end portion of the winding shaft is reliably supported. .

  Next, embodiments of the present invention will be described with reference to the drawings.
