Description

  The present invention relates to a roll-type horizontal sliding screen door that can be opened and closed to the left and right, which is attached to a sash frame such as a door or a window.

Even in today's advanced air-conditioning systems, each window is provided with a screen door for economic efficiency and comfort, and a roll-type door that can store the screen in a sash is devised as a horizontal screen door. .
This roll type horizontal sliding screen door is a rectangular frame composed of upper, lower, left and right ridges, a net stretched over the entire surface of the frame, a winding mechanism incorporated in one of the left and right ridges, A moving rod with the opposite side edge fixed to the collar side edge incorporating the winding mechanism of the mesh, and upper and lower ends of the movable rod slide on the upper and lower collars (guide the upper and lower ends) It consists of a guide body that extends over the entire length of the moving rod (see FIG. 1 of Patent Document 1).
JP 2005-213911 A

  As the guide body, there is a slit formed over the entire length, and the upper edge or the lower edge of the mesh enters the slit so as to be movable in the length direction of the slit (Patent Document 1, Paragraph 0017). 2).

Further, as the mesh winding mechanism, a cylinder that covers the entire length of the cage in which the mesh is wound, a shaft that is inserted into the cylinder and rotatably supports the cylinder, and an outer periphery of the shaft are provided. And a coil spring that applies a force in the direction of winding the net around the cylinder (see FIG. 4 of Patent Document 1).
In this winding mechanism, one end of the coil spring is fixed to the hook, and the other end is provided with a spring force to the tube, and the net is pulled out (moving the moving hook away from the winding mechanism). As the coil spring is tightened, the net is wound by the return force of the coil spring as the net is pulled back (the moving rod is moved toward the winding mechanism).

  This roll-type horizontal sliding screen door moves the moving rod to the left and right, and as it moves, pulls out (rewinds) the net from the winding mechanism or winds it up and down. At that time, since the moving rod is operated manually, the forces acting on the upper and lower ends of the moving rod are difficult to balance, and when winding the net, the moving rod tilts to the left and right. As a result, there is a case where the net is not completely wound into the winding mechanism (see the chain line state in FIG. 2, FIG. 8 (c)).

  Further, the winding mechanism winds the mesh by the restoring force of the coil spring, but the restoring force of the coil spring does not act uniformly on the entire length of the cylinder, and the mesh is not smoothly wound.

  The first object of the present invention is to eliminate the wrinkle by a simple operation even when wrinkles occur in the net, and to completely wind the net into the winding mechanism. A second problem is to make the winding force) uniformly act on the entire length of the cylinder.

  In order to achieve the first object, the present invention is characterized in that a slit is formed over the entire length of the guide body, and the upper edge or the lower edge of the mesh enters the slit, and the length of the slit. In addition to being movable in the vertical direction, a ridge is provided over the entire length of the upper or lower edge of the mesh that has passed through the slit. A guide that is guided without slipping out is adopted, and the end portion on the heel side where the winding mechanism of the guide body is incorporated is separated and connected to the original guide body so as to be swingable in the vertical direction. It was meant.

  When the screen is rolled up (when the screen door is opened), the force applied to the upper and lower ends of the moving rod does not balance, and the moving rod tilts to the left and right. The net on one end side is loosened and the net on the other end side is pulled inward. For example, in FIG. 2, the upper side is loosened and the lower side is pulled. Normally, the net on the loose side is wound around the winding mechanism, and the net on the pulled side is wound by friction with the guide body. In addition, even if the moving rod is moved to the winding mechanism side, the rod does not disappear due to the frictional force or the like and is not easily caught.

  However, if the end of the guide body to be pulled is swingable, the upper edge or lower edge of the net will be guided by the convex line without coming out of the guide body. Accordingly, the end of the guide body swings and absorbs the tensile force (see FIG. 8C). For this reason, a large frictional force is not generated between the net and the guide body (end portion), and if the moving rod is moved to the winding mechanism side, the moving rod pushes down the end portion of the guide body (the guide body). And the net of the net is stretched by the depression, and the net of which the net is stretched is wound up by the winding mechanism. That is, by moving the moving rod along the winding mechanism, the net is completely wound on the winding mechanism (see FIG. 8A).

  Normally, if the same person moves the moving rod, and the inclination of the moving rod often tilts forward as shown by the chain line in FIG. 2, for example, only the end portion of the lower guide body can swing. You can do it. For this reason, only the end of the lower or upper guide body can be made swingable depending on the use mode, but both end portions of the upper and lower guide bodies can be swung so as not to be affected by the use mode. It is preferable that

  As a configuration of the present invention, a rectangular frame composed of upper, lower, left and right ridges, a net stretched over the entire surface of the frame, a winding mechanism incorporated in one of the left and right ridges and winding the mesh, A moving rod having a net winding mechanism incorporated therein and a moving rod fixed on the opposite side edge, and a moving length of the moving rod provided on the upper and lower rods and sliding on the upper and lower ends of the moving rod. The guide body is formed with a slit over the entire length thereof, and the upper edge or the lower edge of the mesh enters the slit and is movable in the length direction of the slit. , A ridge is provided over the entire length of the upper or lower edge of the net that passes through the slit, and the upper or lower edge of the net is guided without coming out of the guide body by the ridge. The end on the heel side where the winding mechanism is incorporated is separated. It is to be adopted which are connected swingably up and down relative to the original guide body.

In this configuration, the upper and lower hooks can be provided with guides that guide the upper and lower ends of the moving hooks without coming out, and the guide body can be positioned inside the guides.
Without this guide, the moving rod is also guided by the guide body, but if this is done, the moving rod will be guided by a separate guide, and the guiding action will be smooth. By smoothing the guide, when the net is wound, when the net is pulled and the end of the guide body swings, the guide body end is pushed down with a moving rod. The net winding action on the mechanism also becomes smoother (see FIG. 8A).

In order to achieve the second problem, the present invention employs the coil spring type in the winding mechanism, and positions the point where the restoring force of the coil spring is applied in the center in the longitudinal direction of the rod. It was decided.
Thus, when the return force is applied to the cylinder at the center in the longitudinal direction of the collar, the return force is applied uniformly over the entire length of the cylinder, so that the winding action is also smoothly performed.
This means is employed in the configuration of the invention that solves the first problem or the configuration in which the end portion of the guide body is not swingable in addition to the well-known horizontal screen described in the above-mentioned publication. can do.

As described above, according to the present invention, since the end portion of the guide body is swingable, the net can be smoothly and completely wound around the winding mechanism.
Further, by winding the cylinder spring by applying the restoring force of the coil spring to the center in the longitudinal direction of the flange, the winding operation can be smoothly performed.

1 to 7 show an embodiment, and this embodiment is also stretched over a square frame 1 composed of upper, lower, left and right ridges 30, 30, 10, and 20 and the entire surface of the frame 1 as in the prior art. A net 5, a net winding mechanism incorporated in one of the left and right cages 10, 20, and a side edge opposite to the collar side edge in which the winding mechanism of the mesh 5 is incorporated (right edge in FIG. 2) The movable rod 6 is fixed, and guide bodies 31 and 31 are provided on the upper and lower rods 30 and 30 and the upper and lower ends of the movable rod 6 slide over the entire moving length of the movable rod 6. Each of the cages 10, 20, and 30 is an aluminum pultruded product.
In addition, since the upper and lower flanges 30 and 30 and the guide bodies 31 and 31 which are the constituent members thereof are vertically symmetrical, both are simply referred to as “the flange 30”, “the guide body 31”, and the like. . In the figure, 7 is a handle, and the net 5 is fixed to the movable rod 6 via a rubber band 8 (see FIG. 7).

  The mesh 5 is provided with one tooth of a slide fastener over the entire length of the upper, lower, left, and right edges, and has protrusions 5a over the entire length (FIGS. 3, 4, and 7). reference).

  The winding mechanism is incorporated in the left basket 10 and has a cylinder 11 that extends over the entire length of the basket 10 around which the net 5 is wound, and is inserted into the cylinder 11 so that the cylinder 11 can freely rotate. And a coil spring 13 that is provided on the outer periphery of the shaft 11 and applies a force in the direction of winding the net 5 around the tube 11.

  The cylinder 11 is fitted with a rotor 17 at both ends, a support shaft 17a is fixed to one rotor 17 (upper side in FIG. 2) (see FIG. 5A), and the other rotor (in FIG. 2). The shaft 12 passes through the lower side in a rotatable manner, and the penetrating portion serves as a support shaft 12a (see FIG. 5D). One support shaft 17a is rotatably supported by a bearing 18 in the flange 10, and the other support shaft 12a is supported by the bearing 18 so as not to rotate. For this reason, the cylinder 11 is rotatable with respect to the shaft 12 and the flange 10 with the shaft 12 as an axis.

  Further, an annular ridge 14 extending over the entire length is formed on a part of the inner surface of the cylinder 11, and the ridge 5 a at the edge of the mesh 5 is inserted into the ridge 14, and the slit 15 of the ridge 14 is inserted into the slit 15. The net 5 is attached to the cylinder 11 by inserting the edge of the net 5 (see FIG. 6). At this time, since the width (thickness) of the ridge 5a of the mesh 5 is set larger than the width of the slit 15, the ridge 5a does not come out of the slit 15, and the tube 11 rotates around the shaft 12, thereby 5 is wound around the cylinder 11.

  Further, a shaft 12 is inserted into the cylinder 11, and a rotor 16 is rotatably fitted on the tip of the shaft 12 and in the middle thereof. The rotor 16 at the tip is immovable in the axial direction of the shaft 12, while the rotor 12 in the middle is movable. Each of the rotors 16 also has a groove 16a on the outer periphery thereof, and each of the rotors 16 and 16 rotates integrally with the cylinder 11 by fitting the protrusions 14 of the cylinder 11 into the groove 16a. A similar groove is formed in the rotor 17 at both ends of the cylinder 11, and the ridge 14 of the cylinder 11 is fitted in the groove, so that the rotor 17 also rotates integrally with the cylinder 11.

  A coil spring 13 is fitted on the outer periphery of the shaft 12. One end (lower end in FIG. 2) of the coil spring 13 is fixed to the shaft 12, and the other end is fixed to the rotor 16 in the middle. When the shaft 12 is rotatable, one end of the coil spring 13 is fixed to the flange 10. The rotor 16 in the middle (the other end of the coil spring 13) is located in the center of the longitudinal direction of the flange 10, and the rotor 16 (the upper side in FIG. 2) beyond that is 4 etc. of the length of the flange 10. Located in the quantile.

  The guide body 31 has a rectangular tube shape, and a slit 32 is formed over the entire length of the guide body 31, and the upper edge or the lower edge of the mesh 5 is formed in the slit 32. It enters so as to be located inside, and is movable in the length direction of the slit 32 (see each figure in FIG. 8). For this reason, the net 5 is guided by the guide body 31 through the slit 32 without coming out.

Further, the end portion 31a on the side of the flange 10 in which the winding mechanism of the guide body 31 is incorporated is separated and connected to the original guide body 31 so as to be swingable in the vertical direction (FIG. 7, (See each figure in FIG. 8). As this connecting means, as shown in FIG. 7, it is possible to use a tape 33, or when the guide body 31 is resin-molded, the connecting portion is made thin so that it can be flexibly integrated.
The upper piece of the guide body end 31a has a trapezoidal shape with both ends cut so that there is no hindrance to the swing when swinging as shown in FIG. The hypotenuse of the trapezoid reaches one surface of the guide body 31.

  The upper and lower ridges 30 have guides 34 composed of L-shaped guide pieces 34a and 34a facing each other, and the guides 34 are moved through slits (a gap between the guide pieces 34a and 34a) 35. The slider 6a of the heel 6 is fitted, and the guide 34 guides the moving heel 6 (slider 6a) without coming out of the heel 30. The guide body 31 is positioned inside the guide 34 (see each figure in FIG. 8). The sliding surface of the slider 6a is an arc surface, and the surface of the moving rod 6 facing the sliding surface is also an arc surface (see FIGS. 7 and 8). Thus, the moving rod 6 moves the guide 34 while absorbing a slight inclination of the moving rod 6.

  This embodiment has the above-described configuration. As in the prior art, this embodiment is attached to a doorway where a screen door is not installed, or to a ridge D of a window W (see FIG. 3). By moving left and right through the upper and lower guides 34, 34, the net 5 is pulled out and taken up from the take-up mechanism to open and close. At this time, as shown in FIGS. 8A and 8B, the net 5 is guided and moved by the guide body 31 as it is pulled out and taken up from the winding mechanism. Further, in a state where the net 5 is closed (a state in which the moving rod 6 in FIG. 2 hits the right rod 20), the contact state is maintained by a magnet or the like provided on the moving rod 6 or the rod 20.

When the mesh 5 is wound (when the screen door is opened), the forces acting on the upper and lower ends of the movable rod 6 are not balanced, and the movable rod 6 tilts left and right, as shown by the chain line in FIG. When wrinkles occur in the net 5, the net 5 at one end (upper side in FIG. 2) of the moving bar 6 is loosened, and the net 5 at the other end (lower side in FIG. 2) is pulled inward. Then, as shown in FIG. 8C, the end portion 31a of the guide body 31 on the side to be pulled also swings upward to absorb the tensile force.
Therefore, a large frictional force is not generated between the net 5 and the guide body 31 (end portion 31a), and the lower end of the moving rod 6 is further moved to the winding mechanism side from the state shown in FIG. 8 (c). Then, as shown in FIG. 8 (a), the moving rod 6 pushes down the end 31a of the guide body 31, and the mesh 5 is stretched by the pushing down, and the mesh 5 from which the collar is stretched is the winding mechanism. Is completely wound.

Moreover, since the point (rotor 16 in the middle) on which the restoring force of the coil spring 13 is applied is located at the center in the length direction of the rod 10 (the center in the vertical direction of the mesh 5), when winding the mesh 5, The return force of the coil spring 13 acts uniformly over the entire length of the cylinder 11, and the winding action is smoothly performed.
Furthermore, when the coil spring 13 is tightened and unwound, the rotor 16 at the other end moves on the shaft 12 to smooth the winding and unwinding action.

  By incorporating the take-up mechanism into the right saddle 20, it is possible to obtain a horizontal screen door that is open to the right. Further, by incorporating a winding mechanism in each of the left and right saddles 10 and 20 and connecting the pair of nets 5 unwound from the both winding mechanisms so as to be separable at the center of the frame 1, a double-folding horizontal sliding screen door It can be.
