FIG. 1 is a front view of a sash 1 according to an embodiment. FIG. 2 is a front view of the net 2 according to the embodiment. FIG. 3 shows a front view of a sash structure 3 configured by arranging the mesh 2 of FIG. 2 on the sash 1 of FIG.

  A sash 1 shown in FIG. 1 is a frame for attaching the net 2 shown in FIG. The sash 1 may be a fixed window frame that is used by being fixed to a building or the like, or may be a movable screen that the sash 1 itself can slide in the horizontal direction.

  As shown in FIG. 1, the sash 1 has an inner edge 6 and an outer edge 7. In the present embodiment, both the inner edge 6 and the outer edge 7 of the sash 1 constitute a rectangular frame. Since the sash 1 has the inner edge 6, the ventilation space 5 is formed in the inner side. Through the ventilation space 5, ventilation can be performed inside and outside the building to which the sash 1 is attached.

  The sash 1 is further formed with a concave groove 4 recessed inward. Specifically, the groove 4 is formed between the inner edge 6 and the outer edge 7 as a rectangular groove similar to the inner edge 6 and the outer edge 7. The groove 4 forms a fixing structure for fixing the net 2 as will be described later.

  A net 2 shown in FIG. 2 is a net used by being arranged and fixed to the sash 1. The net 2 functions as an insect net, for example. The net 2 in the present embodiment includes a net part 9, a fixing end part 10, and a knob part 11. The net part 9 is a sheet knitted in a mesh shape. In the present embodiment, the net portion 9 is formed in a substantially rectangular shape. As a specific example of the net part 9, for example, an 18 mesh having an individual gap size of 1.4 mm is used. The fixing end portion 10 is an end portion of the net 2 provided around the net portion 9 (excluding the corner portion). The fixing end portion 10 corresponds to a portion disposed in the groove 4 of the sash 1 described above. The fixing end portion 10 in the present embodiment is formed by sandwiching and fixing the peripheral portion of the mesh portion 9 with a tape-like member (for example, polyester) having higher rigidity than the mesh portion 9. The knob portion 11 is a knob portion for the user to perform operations such as removal of the network 2. In the present embodiment, the knob portion 11 is provided as a protruding portion protruding from the boundary portion between the net portion 9 and the fixing end portion 10.

  FIG. 3 shows a state in which the fixing end portion 10 of the net 2 shown in FIG. 2 is arranged in the groove 4 of the sash 1 shown in FIG. As shown in FIG. 3, by arranging and fixing the net 2 to the sash 1, the net 2 is stretched so as to close the ventilation space 5 of the sash 1. Thereby, the passage of an object through the ventilation space 5 can be prevented.

  Next, the structure for fixing the net 2 by the grooves 4 of the sash 1 will be described with reference to FIGS. 4 shows a cross section AA in FIG. 1, and FIG. 5 shows a cross section BB in FIG.

  As shown in FIG. 4, the sash 1 includes sash surfaces (surfaces of the sash 1) 12 a to 12 d and protrusions 13 a and 13 b.

  The first sash surface 12 a is a support surface that supports the net 2 in a state of being stretched on the sash 1. The first sash surface 12a is adjacent to the ventilation space 5 and is provided to extend along the vertical direction. The second sash surface 12b is a surface disposed adjacent to the first sash surface 12a and extends substantially perpendicular to the first sash surface 12a. The second sash surface 12 b corresponds to the inner side surface of the sash 1 that forms the groove 4. The third sash surface 12c is a surface disposed adjacent to the second sash surface 12b and extends substantially perpendicular to the second sash surface 12b. The third sash surface 12 c provided in this way constitutes the bottom surface of the groove 4. The fourth sash surface 12d is a surface disposed adjacent to the third sash surface 12c, and extends substantially perpendicular to the third sash surface 12c. The fourth sash surface 12d provided in this way is opposed to the second sash surface 12b and substantially parallel to the second sash surface 12b. The 4th sash surface 12d is equivalent to the inner surface of the sash 1 which forms the groove | channel 4 similarly to the 2nd sash surface 12b. Here, the second sash surface 12b is an inner surface close to the inner side of the sash 1 (the ventilation space 5 side) among the inner surfaces of the sash 1, whereas the fourth sash surface 12d is the sash 1. It corresponds to the inner surface close to the outer side. As shown in FIG. 4, the second sash surface 12 b, the third sash surface 12 c, and the fourth sash surface 12 d mainly constitute a fixing structure of the net 2.

  Such a fixing structure of the net 2 by the grooves 4 of the sash 1 is further provided with a first protrusion 13a and a second protrusion 13b.

  The first protrusion 13 a is a boundary provided between the first sash surface 12 a and the second sash surface 12 b and provided at the entrance portion of the groove 4. The first protrusion 13a in the present embodiment is provided so as to rise substantially vertically from the second sash surface 12b and to protrude toward the opposed fourth sash surface 12d. The tip of the first protrusion 13a in the present embodiment is formed to have a curved cross section (for example, an arc-shaped cross section having a curvature radius of 0.2 mm).

The second protrusion 13b is a protrusion that protrudes from the fourth sash surface 12d that faces the second sash surface 12b. The second projection 13b in the present embodiment has a fourth sash surface 12d so that the tip thereof is located on the back side of the groove 4 (the side closer to the third sash surface 12c) than the first projection 13a. Protruding from. Furthermore, in the present embodiment, the second protrusion 13b protrudes obliquely downward, and the protruding direction is set to be 45 degrees with respect to the fourth sash surface 12d. That is, the second protrusion 13b is in a depth direction C of the groove 4 which is a direction perpendicular to a plane (a plane parallel to the paper surface of FIGS. 1-3) on which the net 2 stretched on the sash 1 extends. Project at an angle of 45 degrees. In the present embodiment, similarly to the tip of the first protrusion 13a, the tip of the second protrusion 13b is also formed to have a curved cross section (for example, an arc-shaped cross section having a curvature radius of 1 mm). . Further, in the present embodiment, the first and second protrusions 13a and 13b are arranged such that the positions of the tips of the first and second protrusions 13a and 13b coincide with each other when viewed from the depth direction C of the groove 4 (one-dot chain line in FIG. 4). See D).

  According to such a configuration, the fixing end 10 is fixed so as not to come out of the groove 4 in a state where the fixing end 10 of the mesh 2 is disposed in the groove 4 as shown in FIG. Can do. Specifically, in the state shown in FIG. 5, it is assumed that an external force is applied to pull the net 2 toward the inside of the sash 1 (the side of the ventilation space 5) (arrow E). In this case, one end of the fixing end portion 10 near the inlet portion of the groove 4 is caught by the tip of the first protrusion 13a and locked (F portion). When the net 2 is further pulled from here, the fixing end portion 10 tries to rotate outward (arrow G) with the tip engaged with the first protrusion 13a as a fulcrum. On the other hand, a second protrusion 13b is provided on the opposite side of the first protrusion 13a across the fixing end 10, and the tip of the second protrusion 13b is a groove 4 than the first protrusion 13a. It is arranged on the back side. Therefore, even if the fixing end portion 10 tries to rotate outward, the movement is restricted by the second protrusion 13b (see H portion). As a result, the fixing end 10 is fixed in the groove 4. According to such a principle, the fixing end 10 can be fixed in the groove 4 so as not to come off. According to the fixing structure, since the net 2 can be fixed to the sash 1 without using a member different from the sash 1, the net 2 can be fixed by a simple method.

As shown by reference sign D in FIG. 4, the positions of the tips of the first and second protrusions 13a and 13b are arranged so as to coincide with each other when viewed from the depth direction C of the groove 4. As shown, since the fixing end 10 and the mesh portion 9 arranged in the groove 4 have a thickness, they are not parallel to the depth direction C but slightly inclined. For fixing, the distance in the depth direction C from the tip of the first protrusion 13a to the third sash surface 12c constituting the bottom surface of the groove 4 is set to be equal to or longer than the length of the fixing end 10 The end 10 can be more reliably locked at the tip of the first protrusion 13a.

In the fixing structure, the fixing end 10 is fixed in the groove 4 by providing the first protrusion 13a and the second protrusion 13b extending from the opposite side. In particular, since the positions of the tips of the first and second protrusions 13a and 13b are arranged so as to coincide with each other when viewed from the depth direction C of the groove 4, the fixing end 10 is more reliably and stable. Thus, it can be fixed so as not to come out of the groove 4.

  When the fixing end 10 is removed from the groove 4, the fixing end 10 is grasped and the net 2 is pulled toward the outside of the sash 1 (opposite to the arrow E). 10 can be released from the engagement with the first protrusion 13a and removed.

  As described above, the sash 1 in the present embodiment has the concave groove 4 for receiving the net 2, and the sash 1 for fixing the net 2 in a state where a part of the net 2 is disposed in the groove 4. An inner side surface (second sash surface 12b, fourth sash surface 12d) arranged to face each other so as to form the groove 4, and an inner side surface (first sash 1) of the inner side surface that is close to the inner side of the sash 1. 2 sash surface 12b), the first projection 13a projecting toward the opposing inner side surface (fourth sash surface 12d), and the inner side surface (second sash surface 12b) provided with the first projection 13a. ) And a second protrusion 13b that protrudes so that its tip is located on the deeper side of the groove 4 than the first protrusion 13a. According to such a configuration, when an external force is applied so that the net 2 is pulled inside the sash 1 with the fixing end 10 disposed in the groove 4, the front end of the first protrusion 13a is engaged. Even if the fixed fixing end portion 10 tries to rotate, the rotational movement is restricted by the second protrusion 13 b, so that the fixing end portion 10 can be fixed in the groove 4. Thus, since the net 2 can be fixed to the sash 1 without using a member different from the sash 1, the net 2 can be fixed by a simple method.

Further, in the present embodiment, when viewed from the depth direction C of the groove, the positions of the tips of the first and second protrusions 13a and 13b are arranged so as to coincide with each other (one-dot chain line D in FIG. 4). reference). According to such a configuration, the space between the first and second protrusions 13a and 13b (for disposing the fixing end 10 in the groove 4) can be secured widely. In addition to preventing 10 from being removed from the groove 4, the fixing end 10 can be easily disposed and attached in the groove 4. That is, it is possible to maintain a good balance between the ease of attaching the net 2 to the sash 1 and the degree of prevention of inadvertent removal of the net 2.

  In the present embodiment, the first protrusion 13 a is provided at the entrance of the groove 4. As a result, compared with the case where the first protrusion 13a is formed by protruding from the middle of the second sash surface 12b, the fixing end 10 of the net 2 is reliably hooked by the tip of the first protrusion 13a. Can be locked. Further, when the first protrusion 13a is molded, the first protrusion 13a can be formed by extending the first sash surface 12a, so that the first protrusion 13a protrudes from the middle of the second sash surface 12b. Compared to the formation, the first protrusion 13a can be easily formed.

  In the present embodiment, the second protrusion 13 b is provided so as to protrude toward the back side of the groove 4. According to such a configuration, even when the fixing end 10 of the net 2 is engaged with the first protrusion 13a in the groove 4 and tries to rotate outward, the rotation is more reliably performed. Since it can regulate, the net | network 2 can be fixed to the sash 1 more reliably and stably.

  In the present embodiment, the second protrusion 13 b is protruded so as to form an angle of 45 degrees with respect to the depth direction C of the groove 4. According to such a configuration, when the fixing end portion 10 of the mesh 2 is about to rotate outward in the groove 4 while being engaged with the first protrusion 13a, the rotation is more reliably regulated. Therefore, the net 2 can be fixed to the sash 1 more reliably and stably.

  In the present embodiment, the tip of the first protrusion 13a is curved. According to such a configuration, when the fixing end 10 is disposed and fixed in the groove 4 as compared with the case where the tip of the first protrusion 13a has a sharp shape, the fixing end 10 is It is possible to suppress damage at the tip of the first protrusion 13a. Furthermore, in the present embodiment, the fixing end portion 10 is made less likely to come off from the tip end of the first protrusion 13a by forming the radius of curvature as 0.2 mm, which is the smallest radius of curvature in terms of manufacturing. be able to.

Although the present invention has been described with reference to the above-described embodiments, the present invention is not limited to the above-described embodiments. For example, in the present embodiment , the first and second protrusions 13a and 13b are disposed so that the positions of the tips of the first and second protrusions 13a and 13b coincide with each other when viewed from the depth direction C of the groove 4. However, this is not the only case. Absent. For example, the net 2 can be fixed in the groove 4 regardless of whether the first and second protrusions 13a and 13b overlap along the depth direction C of the groove 4 or not. it can. This point will be described with reference to FIGS.

FIGS. 6 and 7 are schematic views showing the force acting on the second protrusion 13b (not shown) from the fixing end 10 in a state of being locked at the tip of the first protrusion 13a (not shown). FIG. The example shown in FIG. 6 shows a case where the fixing end portion 10 is inclined toward the second sash surface 12b side (inside the sash 1) from the entrance side of the groove 4 toward the back side. As a configuration in which the state shown in FIG. 6 is realized , the positions of the tips of the first protrusion 13a and the second protrusion 13b are mutually different when viewed from the depth direction C of the groove 4 as in the above-described embodiment. The case where it corresponds, the case where the 1st protrusion 13a and the 2nd protrusion 13b mutually overlap along the depth direction C of the groove | channel 4 , or the case where it is slightly separated is mentioned. The example shown in FIG. 7 shows a case where the fixing end portion 10 is inclined toward the fourth sash surface 12d side (outside of the sash 1) from the entrance side to the back side of the groove 4. 7 is realized, the first protrusion 13a and the second protrusion 13b do not overlap each other along the depth direction C of the groove 4, and are predetermined in the vertical direction (left and right direction in FIG. 7). The case where it arrange | positions with the above space | intervals is mentioned.

  In the example shown in FIG. 6, the direction of the force F <b> 1 acting on the second protrusion 13 b from the fixing end portion 10 is a direction perpendicular to the surface of the fixing end portion 10, and is outside the sash 1 and the groove 4. It is a direction toward the back side. The force F1 is decomposed into a vertical component F1a and a horizontal component F1b. The horizontal component F1b is a direction toward the back side of the groove 4. Since the horizontal component F1b is in the direction toward the back side of the groove 4 as described above, it acts so as to go toward the back side of the groove 4, so that the fixing end portion 10 is not easily removed from the groove 4. On the other hand, in the example shown in FIG. 7, the direction of the force F <b> 2 that acts on the second protrusion 13 b from the fixing end portion 10 is a direction perpendicular to the surface of the fixing end portion 10. This is the direction toward the inlet side of the groove 4. The force F2 is decomposed into a vertical component F2a and a horizontal component F2b. The horizontal component F2b is a direction toward the inlet side of the groove 4. Since the horizontal component F2b is in the direction toward the inlet side of the groove 4 as described above, the fixing end 10 acts toward the inlet side of the groove 4. Even in the case shown in FIG. 7, since the second protrusion 13 b is provided, the net 2 can be fixed in the groove 4, but the fixing end 10 is more difficult to be removed from the groove 4. In that respect, the state shown in FIG. 6 is superior to the state shown in FIG. In view of such circumstances, the fixing length of the fixing end 10 in the groove 4 may be determined by adjusting the protruding lengths of the first and second protrusions 13a and 13b.

  Further, in the present embodiment, a case has been described in which the fixing end portion 10 is provided in the net 2 and the net 2 is fixed to the sash 1 by disposing the fixing end portion 10 in the groove 4. Not limited to cases. Even a net that does not have the fixing end portion 10 can be fixed using the sash 1 in the present embodiment described above. Specifically, as shown in FIG. 8, in a state where the mesh 14 having no fixing end is stretched on the groove 4 of the sash 1, the mesh 14 is formed in the groove 4 by a fastener 15 that is a separate member from the sash 1. It can be pressed and fixed inside. By such a method, the net 14 having no fixing end can be fixed to the sash 1. The sash 1 in the present embodiment can be applied to the net 2 having the fixing end 10, but can also be applied to the net 14 having no fixing end, and has a wide application range and high convenience. Have sex.

  Further, in the present embodiment, the case where the fixing end portion 10 is formed by sandwiching and fixing the peripheral portion of the mesh portion 9 with a tape-like member (for example, polyester) having higher rigidity than the mesh portion 9 has been described. It is not limited to such a case. For example, the fixing end portion 10 may be formed by fixing a tape-like member only on one side instead of sandwiching the peripheral portion of the net portion 9.

  The present invention can be applied to any sash structure configured by arranging a sash for receiving a window and a net in the sash.
