  However, in the net tension device described in Patent Document 1, when the rubber packing is sequentially press-fitted into the groove of the screen door frame, the tension force introduced into the screen fluctuates, so that the mesh misalignment with respect to the screen door frame is changed. There is a problem that this misalignment causes wrinkles. That is, when the rubber packing is press-fitted into the screen door frame on the side where the fixing device and the operation device are provided, the mesh of the press-fitted portion is drawn into the groove of the screen door frame, so that the screen clamping member of the operation device is the screen door frame. As a result, the tension of the net becomes uneven between the portion where the rubber packing is pressed and the portion where the rubber packing is not pressed. Further, when the rubber packing is press-fitted into the screen door frame on the side intersecting with the fixing device and the operation device, the rubber packing is press-fitted from the one end side to the other end side toward the other end side. The net is gradually loosened, and the tension is reduced or lost at the end of press-fitting than at the start of press-fitting. Thus, in the net tension device of patent document 1, since the tension of the net becomes uneven or decreases, there is a possibility that mesh misalignment may occur and the net will be wrinkled. There is.

  An object of the present invention is to provide a net tensioning device for a screen door that can reliably prevent mesh misalignment and wrinkle with a simple structure, and a method for fixing the net.

  A net tensioning device for a screen door according to the present invention is a screen door comprising a frame body framed in a square shape and a net fixed to the frame body. A mesh tensioning device for a screen door that holds the mesh and introduces tension to the mesh to prevent misalignment when press-fitting with a material to fix the mesh. A base part installed immovably, a slide part provided on the base part, a holding part for holding the net, and a biasing part connected to the holding part in a direction away from the frame. An urging portion, and on a predetermined side of the frame body, parallel to the mesh receiving groove at an extension position on the other end side of the mesh receiving groove into which the mesh presser material is sequentially press-fitted from one end to the other end. The holding part is slidably installed, and the net is held by this holding part. Rutotomoni, the network against the biasing force of the biasing unit that pulls the one end side, characterized in that the parallel tension to the network receiving grooves are introducible configured on the network.

  Here, as the predetermined side of the frame body, when a net presser material is sequentially bent and press-fitted into a net receiving groove that is continuous on four rounds in an overall substantially square-shaped frame body, the net presser material is first press-fitted. It is preferable that it is one side (1st side, for example, vertical hook). Furthermore, the other side (second side, for example, the side, or the third and fourth sides) into which the mesh presser material is sequentially press-fitted after the first side may be set as a predetermined side. In addition, when the frame has an intermediate beam and is formed in a substantially letter shape as a whole, the intermediate beam may be a predetermined side.

According to such a configuration, when fixing the net by pressing the net presser material into the net receiving groove from one end side of the predetermined one side of the frame body, the tensioning device installed on the other end side of the one side causes the net to Since the tension force is introduced, the net does not gradually loosen toward the other end side, and the net presser can be pressed in with the tension force always introduced. A screen door can be manufactured while preventing wrinkles with certainty.
Further, the net tensioning device can be configured with a simple structure including only the base portion, the holding portion, and the biasing portion. At this time, the holding portion may hold the net at the extended position on the other end side of the net receiving groove and introduce tension to the net, and the net is stretched over the entire length (or full width) of the frame body as in the past. Since it is not necessary to fix the device, the device can be miniaturized and the device can be shared regardless of the size (length or width) of the frame.

At this time, in the net tension device for a screen door of the present invention, it is preferable that the urging portion is constituted by a constant load spring that generates a constant urging force regardless of the sliding amount of the holding portion.
According to such a structure, a constant tension force is introduced into the net by the constant load spring, that is, the net loosens while the net presser is sequentially press-fitted from one end side to the other end side of the predetermined side. Therefore, since the tension force is maintained constant, it is not necessary for the operator to adjust the tension force by hand or the like, and misalignment and wrinkle can be surely prevented even if the worker is not a skilled worker.

  On the other hand, the method for fixing a net for a screen door according to the present invention is a screen door provided with a frame body framed in a rectangular shape and a net fixed to the frame body, in a mesh receiving groove provided in the frame body. A net fixing method for a screen door that is press-fitted together with a net presser to fix the net, and is provided so as to be slidable on the base, and a base that is installed so as not to move with respect to the frame. Using a mesh tensioning device that includes a holding portion that holds the mesh and a biasing portion that is connected to the holding portion and biases the holding portion in a direction away from the frame, a predetermined side of the frame In the above, the holding portion is slidable in parallel with the mesh receiving groove at the other end extended position of the mesh receiving groove into which the mesh presser material is sequentially press-fitted from one end to the other end. While holding the net, against the biasing force of the biasing portion By pulling the one end to the one end side, a tension force parallel to the mesh receiving groove is introduced into the mesh, and with the tension force being introduced, the mesh is press-fitted into the mesh receiving groove together with the mesh retainer. It is characterized by being fixed to a frame.

  According to such a configuration, the screen door can be manufactured by reliably preventing mesh misalignment and wrinkles as described above, and the tensioning device can be miniaturized and shared.

Next, a method for fixing the net 3 in the present embodiment will be described with reference to FIGS.
6A to 9H are plan views showing the procedure for fixing the net 3 respectively.
When the net 3 is fixed, first, as shown in FIG. 6 (A), the screen door frame 2 is set on the work table B with the net receiving groove 2B facing upward, and a pair of fixing treatments provided on the work table B are set. The screen door frame 2 is fixed to the work table B by bringing the tool C into contact with the inner side surface of the facing saddle member 2A (vertical rod in this embodiment). At this time, the side surface of the saddle member 2A (vertical rod) is aligned with the positioning stripe D provided on the work table B so that the screen door frame 2 is parallel to the work table B. The stripes D are formed from, for example, a color tape color-coded with a width of 1 mm, and a plurality of stripes D are provided at the edge of the work table B along the saddle material 2A (vertical rod). The press-fitting of the rubber rope 4 to be described later is started from one end side (right side in the drawing) of the saddle material 2A (lower vertical rod in the drawing) aligned with the stripe D. That is, in the drawing, the lower ridge material 2A (vertical fence) is a predetermined one side of the screen door frame 2 in the present embodiment.

  Then, the net 3 is pulled out from the net supply device E installed adjacent to the work table B, and the net 3 is covered on the upper surface of the screen door frame 2. At this time, colored warp yarns (for example, white yarns) provided at the lower end of the net 3 in the drawing so that the warp yarns of the net 3 (yarns extending in the left and right directions in the drawing) are parallel to the collar 2A (longitudinal warp). , Not shown) is aligned with the stripe D. Further, the weft thread (the thread extending vertically in the figure) of the net 3 is arranged so as to be parallel to the braid 2A (horizontal barb) that intersects the braid 2A (vertical barb) where the rubber rope 4 starts to be press-fitted. .

Next, as shown in FIG. 6 (B), the net 3 is cut so that the tip of the net 3 is left by a predetermined length (for example, 50 to 100 mm) from the screen door frame 2.
After the net is cut, the tensioning device 10 is installed on the other end side (left side in the figure) of the saddle member 2A (the lower vertical hook in the figure) where the rubber rope 4 starts to be press-fitted. That is, the front contact portion 14 and the side contact portion 15 on the front surface of the base portion 11 are brought into contact with the saddle member 2A, and the net holding portion 12 is in an extended position of the mesh receiving groove 2B of the saddle member 2A. The tensioning device 10 is installed. Then, the handle 19 of the net holding unit 12 is operated to hold the other end side end of the net 3 between the clamp rubber 22 and the clamp plate 21.
