[Prior art]

 Screen doors are often used in various houses and buildings, including ordinary houses. This screen door is a fitting used to improve ventilation in the room and also to prevent pests and dust from entering the room. At present, so-called aluminum sash screen doors are widely used. By the way, if the screen of the screen door is damaged or becomes contaminated, the screen must be replaced. In reshuffling the mesh of this screen door, remove the mesh holding rubber, remove the old mesh, spread the new mesh on the screen door frame, and connect the string-like mesh holding rubber together with the mesh in the groove on the periphery of the screen door frame. It is done by the procedure of pushing in one after another and fixing the net. In order to prevent the mesh itself from wrinkling, it is necessary to press the rubber elastic while pressing the mesh door and mesh with this mesh replacement, and if the mesh door and mesh position are accurately fixed, The pressing rubber string was displaced from the groove into which it should be fitted, making it difficult to push it in, and it was not something that a housewife at home, for example, could easily do. As described above, the problem of refitting the screen door is that it is easy and quick to install the net presser rubber, and there has been a strong demand for a means by which housewives at home can easily refit the screen. Further, there are several kinds of widths for the mesh pressing rubber of the screen door, and 4 to 5 kinds of the mesh pressing rubber having different thicknesses are commercially available. On the other hand, there is usually only one type of rubber pushing roller having an appropriate width, which is attached to the mesh holding rubber fitting. When the rubber pushing roller is used in actual netting work, if the width of the groove is wide (the rubber is thick), the roller easily comes off the rubber and the work does not proceed well. If the width of the groove is narrow, the roller will not fit in the groove and will not be useful. Therefore, there are inconveniences such as preparing a plurality of net-pressing rubber fittings having rollers with different widths. In addition, there was a drawback that the rubber came off the roller when it was pushed into the roller, making it difficult to push.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 shows an embodiment of the present invention. The mesh door rubber mounting diagram of the screen door shown in this figure is mainly composed of the grip portion 1 and the two pushing roller portions. The two pushing roller parts of the present invention are those in which the disc-shaped pushing rollers 2, 2'are rotatably attached to the mandrel 6, 6'perpendicular to the slits 5, 5'provided at both ends of the jig of the present invention. Is. The widths of the slits 5 and 5'are made larger than the width of the frame groove, and the widths of the pressing rollers 2 and 2'are formed so as to fit between the frame grooves. As shown in FIG. The mounting tool requires that the push-in rollers 2 and 2'be made to protrude from the tips 9 and 9'of the slits. Since the tips 9 and 9'of the slits are slid in contact with the frame surface of the screen (shown by the dotted line L), the pressing rubber is pushed deeper than the frame surface L by the length of this protruding portion. Two rollers having different widths of the projecting portions are mounted as pushing rollers 2 and 2 ', respectively. When carrying out a mesh pushing operation in a screen door having different groove widths, any one of the pushing rollers 2, 2'suitable according to the width of the groove can be appropriately selected and used. Further, as shown in FIGS. 2 and 3, a step is provided on the outer peripheral edge of the push-in rollers 2, 2 '(diameter of the diameter differs depending on the front and back of the roller). By providing such a step, the pressing rubber does not come off from the roller, and the pushing operation can be performed reliably. Without this step, when the pushing force is applied, the rubber comes off the roller, which increases the frictional force with the groove side surface, and a great amount of force is required for the pushing operation. The shape of the step of the pressing roller can be appropriately selected according to the shape of the pressing rubber. The following is a description of a normal procedure for reattaching the screen of the screen using the screen retainer rubber fitting of the screen. (1) First, remove the mesh retainer rubber on the screen door, remove the old mesh, and clean the groove with a brush. (2) Then, cut a new mesh slightly larger than the groove for fixing the mesh around the screen door frame, spread it on the frame, and temporarily fix it with clips. (3) According to the width of the screen door groove and the thickness of the rubber, select a push-in roller that matches the dimensions. (4) First, for example, push the rubber from the short side of the screen frame, and then move to the long side. At this time, be careful not to distort the mesh due to the force of being pushed in and the mesh and crosspieces should not shift from parallel. (5) The side with the larger diameter of the roller, that is, the protruding side of the outer peripheral edge of the roller is pressed against the net so that the roller is pressed. (6) First, the end of the net-pressing rubber cord is pushed into the corner of the screen door frame by the tip of the pawl 3 provided on the mesh-pressing rubber fitting. (7) In this way, rubber is pushed into each side of the screen frame one after another. At this time, if the net is slightly pulled outward and the net-pressing rubber fitting is driven, the slack of the net is eliminated and the finish becomes beautiful. (8) Finally, cut off the excess net with a cutter knife, etc., and the net reshuffling is completed. The screen retainer rubber fitting of the screen door according to the present invention may be made of metal, wood, bamboo, etc., but is preferably made of synthetic resin in view of manufacturing and cost. The size is also arbitrary and may be within a range that can be manually operated. The screen retainer rubber mounting device of the screen door of the present invention is not limited to that shown in FIG. 1, and may have any structure as long as it has the above-mentioned handle portion and two pushing rollers. Good.
