  Since the raising and lowering window as described above always exerts the elastic force that the braking leaf spring provided on the Yukimi frame frame presses horizontally with the bottom wall of the sliding groove, When the Yukimi frame frame is moved upward, the weight of the Yumi frame frame and the frictional force between the braking leaf spring and the bottom wall portion of the sliding groove act. For this reason, a larger force may be required when moving the Yukimi frame frame upward. In particular, when the shoji to be moved upward is provided with glass, the weight of the shoji itself increases and the frictional force required to hold the shoji in the raised position also increases, so the shoji There is a problem that the force required when moving the lens to the position is further increased and the operability is poor.

  This invention is made | formed in view of this subject, The place made into the objective is to provide the raising / lowering window which is easy to move a shoji upward.

According to such a raising / lowering window, the front-end | tip of the elastic protrusion part provided in the shoji presses a frame from the upper side. For this reason, a compressive force along the protruding direction of the elastic projecting portion acts on the elastic projecting portion at the base end of the projecting shoji side due to the dead weight of the shoji screen, and the reaction force of the compressive force pushes the shoji upward. Since it acts in the direction, it is possible to reduce the force required to hold the shoji in place.

In addition, the reaction force increases the force with which the distal end side of the elastic protruding portion presses the frame . When the shoji is moved downward, the elastic protrusion is further compressed, so that the force acting in the direction of pushing the shoji upward is larger than the reaction force of the compressive force. Furthermore, since the force which presses the frame body by reaction force also becomes large, a frictional force increases and the force which suppresses the downward movement of a shoji becomes large.

  On the other hand, when the shoji is moved upward, it moves along the protruding direction of the elastic protruding portion, and the elastic protruding portion is not compressed. For this reason, it is possible to move the shoji upward smoothly. That is, when the shoji is held in a predetermined position or moved downward, a large force is exerted to suppress the downward movement of the shoji, and when the shoji is moved upward, the load acting on the shoji Therefore, it is possible to provide a raising / lowering window that can easily move the shoji screen upward.

In this raising and lowering window, the frame body includes an end portion in the left-right direction of the shoji, and includes a groove portion having a portion facing the end portion, and the portion of the end portion facing the groove portion is the It is desirable to have an elastic protrusion.

And a resiliently projecting elastic projecting portion projecting upward from the horizontal and in contact with the end portion of the shoji .

According to such a hung window, the tip of the elastic protruding portion provided on the frame side presses the sash from the lower side in. Therefore, the elastic protrusions by the weight of the sliding door, at the frame side of the proximal end which projects, compressive forces along the protruding direction of the spring arms acts, the reaction force of the compressive force shoji upward Since it acts in the pushing-up direction, it is possible to reduce the force required to hold the shoji in place.

In addition, the reaction force increases the force with which the distal end side of the elastic protrusion presses the shoji . When the shoji is moved downward, the elastic protrusion is further compressed, so that the force acting in the direction of pushing the shoji upward is larger than the reaction force of the compressive force. Furthermore, since the force which presses the edge part of the shoji by reaction force also becomes large, a frictional force increases and the force which suppresses the downward movement of a shoji becomes large.

  On the other hand, when the shoji is moved upward, it moves along the protruding direction of the elastic protruding portion, and the elastic protruding portion is not compressed. For this reason, it is possible to move the shoji upward smoothly. That is, when the shoji is held in a predetermined position or moved downward, a large force is exerted to suppress the downward movement of the shoji, and when the shoji is moved upward, the load acting on the shoji Therefore, it is possible to provide a raising / lowering window that can easily move the shoji screen upward.

In the foregoing hung window, the frame houses the end portion in the lateral direction of the shoji, it is desirable to have Bei Ete a groove having the a portion sliding guide portion facing the said end portion.

  According to such a raising / lowering window, since the end of the shoji is accommodated and the elastic protrusion is provided in the groove that moves in the vertical direction, it is ensured between the end of the shoji and the groove of the frame. The elastic protrusion can be brought into contact. Moreover, since the elastic protrusion part is arrange | positioned in the groove part of a frame, an elastic protrusion part is not exposed outside. For this reason, it is possible to provide a raising / lowering window having excellent operability and excellent design.

  In such a raising / lowering window, it is preferable that the elastic protruding portion is a hair-like hair portion.

  According to such a raising / lowering window, since the elastic protrusion is hairy, when the shoji starts to move downward, it is compressed while being bent and is pressed by the other member to increase the compression force and friction force. The downward movement of the shoji is suppressed. Also, when the shoji moves upward, the individual hairs are easy to follow along the shoji movement direction, so the load is small and the contact area is small even if each hairy part touches the other part. Therefore, it is possible to reduce the load acting on the shoji.

In such a raising / lowering window, the elastic protrusion may be a fin-like portion having a fin shape.
According to such a raising / lowering window, since the elastic protrusion is fin-like, it is possible to increase the rigidity compared to the hair-like member, and when the shoji starts to move downward, the shoji can be moved downward more. It is possible to suppress.

In this raising and lowering window, the elastic protrusion may be a raised portion having a raised curved surface.
According to such a raising / lowering window, since the elastic protrusion is a raised curved surface, it is easier to process than an elastic protrusion such as a fin.

  The two sliding guide portions 20b extended from the both ends of the guide body 20a can swing with both ends of the guide body 20a as a fulcrum by the elasticity of the guide member 20, and face each other. The sliding guide portion 20b curved so as to swell in the direction can be elastically deformed in a flattening direction. Here, the guide member 20 may be configured to have elasticity as a whole, or may be configured such that only the bent portions and the sliding guide portions 20b at both ends of the guide main body portion 20a have elasticity.

  In the sliding guide portion 20b of the present embodiment, as shown in FIG. 7, the left and right end portions 11b and 11c of the resin plate 11a and the sliding member 17 are protruded upward from the horizontal at portions facing each other. A mohair 21 is provided as a hair-like portion in which fibers are provided in a raised shape (brush shape) so as to be pressed against the sliding piece 173. Here, the mohair 21 corresponds to an elastic protrusion that can be elastically deformed.

  The sliding guide portions 20b provided so as to face the inner side of the guide main body portion 20a are provided so as to be elastically deformable with each other, and are provided so as to press each other in a direction facing each other. As shown in FIG. 8, the left and right end portions 11b and 11c of the resin plate 11a and the sliding piece 173 of the sliding member 17 are provided with a mohair 21 between the opposing sliding guide portions 20b. Are accommodated so as to be divided in the prospective direction and are opposed to the sliding guide portion 20b. That is, the left and right end portions 11b and 11c of the resin plate 11a and the sliding piece 173 of the sliding member 17 are connected to the moire 21 of the sliding guide portion 20b facing in the prospective direction, and the elasticity of the sliding guide portion 20b and mohair 21. When the raising / lowering shoji 11 is moved up and down, it slides with the mohair 21. Here, the guide member 20 having the U-shaped guide main body portion 20a corresponds to a groove portion that accommodates the end portions 11b and 11c in the left-right direction of the raising / lowering shodder 11, and the support frame 12 is located above and below the raising / lowering shoddy 11 It corresponds to a frame that guides movement in the direction.

  In order to align the position of the sliding guide portion 20b with the resin plate 11a and the sliding piece 173, which are offset from the center of the width in the prospective direction of the upper rod 15 and the lower rod 16 to the outdoor side. A guide member 20 is provided on the shoji region 121 c of the frame member 121 via the spacer 19. Further, in the guide main body portion 20 a of the guide member 20, the depth X1 in the left-right direction in the guide main body portion 20 a from the edge on the inner peripheral side of the support frame body 12 is equal to that of the sliding piece 173 provided on the sliding member 17. It is formed to be larger than the protruding amount X2 from the closing portion 172.

  And when attaching the raising / lowering shoji 11 to the support frame 12 attached with the connection frame member 14 to the inner peripheral side of the frame 9, it was temporarily fixed to the left side of the upper collar 15 and the lower collar 16 in advance. The sliding member 17 is arranged on the rightmost side as shown in FIG.

  Next, the left end portion 11c of the resin plate 11a is positioned between the mohair 21 provided on the sliding guide portion 20b facing the guide member 20 provided on the left support frame member 121, and the left side of the resin plate 11a is the right side. It is inserted in an inclined state so as to be located on the outdoor side. At this time, the resin plate 11a is inserted so that the left end portion 11c is located on the back side of the guide main body portion 20a from the position where the resin plate 11a should be originally mounted.

  Next, the right end portion 11b side of the resin plate 11a is opposed to the mohair 21 as an elastic protrusion provided on the sliding guide portion 20b facing the guide member 20 provided on the right support frame member 121. After moving to the outdoor side as described above, the right end portion 11b of the resin plate 11a is inserted between the mohairs 21 provided on the sliding guide portions 20b opposed to the guide member 20 by moving in the right direction.

  Next, in a state where the closing portion 172 of the right sliding member 17 is in contact with the inner window wall portion 121a of the right support frame body 12, the guide member 20, and the inner peripheral side tip of the spacer 19, The sliding member 17 on the left side of the heel 15 and the lower heel 16 is slid to the left to obtain the state shown in FIG. At this time, as shown in FIG. 3, the interval L1 in the left-right direction of the closing portion 172 included in the left and right sliding members 17 is the inner window wall portion 121a of the left and right support frame bodies 12, the guide member 20, and the spacer 19. The left sliding member 17 is permanently fixed so as to be slightly narrower than the interval L2 in the left-right direction of the circumferential tip.

  The lifting / lowering shoji 11 mounted as described above is provided with a mohair 21 provided on the sliding guide portion 20b of the guide member 20 on the left and right end portions 11b and 11c of the resin plate 11a and the sliding piece 173 of the sliding member 17. Each of the hair-like fibers protrudes so that the end portions 11b and 11c of the resin plate 11a and the sliding piece 173 side of the sliding member 17 are located above the guide member 20 side, and the end portion 11b of the resin plate 11a. , 11c.

  And when moving the raising / lowering shoji 11 upwards, as shown in FIG. 10, the mohair 21 in contact with the surface of the resin plate 11a moving upward is between the mohair 21 and the surface of the resin plate 11a. However, it is only the adjacent fibers that restrict the movement of the fibers of the mohair 21 in the direction away from the resin plate 11a at this time, and the fibers of the mohair 21 are the resin plates 11a. Since it is inclined so as to approach the resin plate 11a while moving upward, the force with which the mohair 21 is pressed toward the resin plate 11a is weak, and the rising / lowering shodder 11 acting on the raising / lowering shodder 11 is restricted. The power is reduced. Therefore, the raising / lowering shoji 11 can be easily moved upward.

  On the other hand, when moving the raising / lowering shoji 11 downward, as shown in FIG. 11, since the resin plate 11a moves against the direction of the mohair 21, the mohair 21 in contact with the surface of the resin plate 11a is When pressed downward by friction generated between the mohair 21 and the surface of the resin plate 11a, a force that compresses the mohair 21 in the length direction acts. The mohair 21 is compressed between the resin plate 11a and the sliding guide portion 20b, and an upward force acts on the resin plate 11a due to a reaction force of the compressive force, and the moire 21 pushes the resin plate 11a. As the height increases, the frictional force generated between the mohair 21 and the surface of the resin plate 11a also increases, and the force that regulates the lowering of the raising / lowering shoji 11 increases.

  According to the raising / lowering window 10 of this embodiment, the sliding guide portion of the guide member 20 is accommodated in the guide member 20 that houses the end portions 11b, 11c of the resin plate 11a of the raising / lowering shoji 11 and the sliding piece 173 of the sliding member 17. The tip of the mohair 21 that protrudes from the 20b side and presses the raising / lowering shoddle 11 presses the end portions 11b, 11c and the sliding piece 173 of the raising / lowering shoji 11 from the lower side. Therefore, a compressive force along the protruding direction of the mohair 21 acts on the mohair 21 at the proximal end of the mohair 21 on the side of the projecting sliding guide portion 20b due to the weight of the raising and lowering shoji 11, and the reaction force is raised and lowered. Since it acts in the direction which pushes up the shoji 11 upwards, it is possible to reduce the force required to hold the raising / lowering shoji 11 in a predetermined position.

  Further, the reaction force increases the force with which the front end side of the mohair 21 presses the end portions 11 b and 11 c of the resin plate 11 a and the sliding piece 173 of the sliding member 17. And when moving the raising / lowering shoji 11 downward, the mohair 21 is further compressed, so that the force acting in the direction of pushing the raising / lowering shoji 11 upward is larger than the reaction force. Furthermore, since the force that presses the end portions 11b and 11c of the resin plate 11a and the sliding piece 173 of the sliding member 17 due to the reaction force is increased, the frictional force is increased, and the force that suppresses the downward movement of the raising / lowering shoji 11 is suppressed. growing.

  On the other hand, when the raising / lowering shoji 11 is moved upward, it moves along the protruding direction of the mohair 21 and the mohair 21 is not compressed, so that a compression force and a friction force are hardly generated. For this reason, it is possible to move the raising / lowering shoji 11 upwards more smoothly. That is, when the raising / lowering shoji 11 is held in a predetermined position or moved downward, a force that suppresses the downward movement of the raising / lowering shoji 11 is greatly applied, and when the raising / lowering shoji 11 is moved upward, It is possible to reduce the load acting on the raising / lowering shoji 11 and to provide the raising / lowering window 10 that makes it easy to move the raising / lowering shoji 11 upward.

  In the present embodiment, the example in which the mohair 21 is provided on the sliding guide portion 20b of the guide member 20 has been described. However, the mohair 21 is provided on the end portions 11b and 11c of the resin plate 11a and the sliding piece 173 side of the sliding member 17. It is possible to provide a configuration that moves between the opposing sliding guide portions 20b. At this time, it is desirable that the fibers of the mohair 21 protrude downward from the horizontal from the ends 11b and 11c of the resin plate 11a and the sliding piece 173 of the sliding member 17. In this case, the ends of the lifting / lowering shoji 11, that is, the ends 11 b and 11 c of the resin plate 11 a and the tip of the mohair 21 provided on the sliding piece 173 of the sliding member 17 are connected to the sliding guide portion of the guide member 20. 20b is pressed from above. For this reason, due to the weight of the lifting / lowering shoji 11, the mohair 21 follows the protruding direction of the mohair 21 at the end portions 11 b and 11 c of the protruding resin plate 11 a and the base end of the sliding member 17 on the sliding piece 173 side. Since the compressive force acts and the reaction force acts in the direction of pushing up and lowering the shoji 11 upward, it is possible to reduce the force required to hold the raising and lowering shoji 11 in a predetermined position.

  Further, the reaction force increases the force with which the distal end side of the mohair 21 presses the sliding guide portion 20 b of the guide member 20. And when moving the raising / lowering shoji 11 downward, the mohair 21 is further compressed, so that the force acting in the direction of pushing the raising / lowering shoji 11 upward is larger than the reaction force. Furthermore, since the force which presses the sliding guide part 20b by reaction force also becomes large, a frictional force increases and the force which suppresses the downward movement of the raising / lowering shoji 11 becomes large.

  On the other hand, when the raising / lowering shoji 11 is moved upward, it moves along the protruding direction of the mohair 21 and the mohair 21 is not compressed, so that a compression force and a friction force are hardly generated. For this reason, it is possible to move the raising / lowering shoji 11 upwards more smoothly. That is, when the raising / lowering shoji 11 is held in a predetermined position or moved downward, a force that suppresses the downward movement of the raising / lowering shoji 11 is greatly applied, and when the raising / lowering shoji 11 is moved upward, It is possible to reduce the load acting on the raising / lowering shoji 11 and to provide the raising / lowering window 10 that makes it easy to move the raising / lowering shoji 11 upward.

  In this embodiment, since the elastic protrusion is the hair-like mohair 21, when the raising / lowering shoji 11 starts to move downward, it is compressed while being bent and the mohair 21 protrudes. The compression force and the friction force are increased by being pressed from the distal end side, and the downward movement of the lifting / lowering shoji 11 is suppressed. Further, when the raising / lowering shoji 11 moves upward, the individual fibers of the mohair 21 are easy to follow along the moving direction of the raising / lowering shoji 11, so that the load is small, and each hairy fiber has an end portion 11b of the resin plate 11a. 11c and the sliding piece 173 of the sliding member 17, the contact area is small, so that the load acting on the raising / lowering shoji 11 can be kept small.

  Further, the elastic protrusion is not limited to the mohair 21. For example, as shown in FIG. 12, a fin-like portion 22 having a fin shape made of a soft synthetic resin has its tip positioned above or below the base end. The sliding guide portion 20b may be provided. In this case, since the fin-like portion 22 has a fin shape, the rigidity can be increased more than that of the hair-like mohair 21, and when the raising / lowering shoji 11 starts to move downward, the raising / lowering shoji 11 It is possible to further suppress the downward movement. Further, as shown in FIG. 13, the elastic protruding portion may be a raised portion 23 having a raised curved surface and having a raised tip located above or below the base end. In this case, since the elastic protrusion is a raised curved surface, processing is easy.

  In the above-described embodiment, the support frame 12 includes the guide member 20 that forms a groove, and the end portions 11 b and 11 c of the resin plate 11 a of the raising and lowering shoddle 11 and the sliding piece 173 of the sliding member 17 are the guide member 20. However, the present invention is not limited to this. For example, as shown in FIG. 14, the raising / lowering shoji 111 includes the vertical hook 112, provided on the outer periphery of the vertical hook 112, recessed on the inner peripheral side, and provided on the support frame 113 on the groove portion 112 a along the vertical direction. It may be the raising / lowering window 110 in which the projecting portion 113a projecting into the housing is accommodated. In this case, an elastic protrusion such as the mohair 21 is provided at a position facing the protrusion 113a disposed between the sliding guide parts 114a of the guide member 114 provided in the groove 112a. Further, the position where the elastic protrusions such as the mohair 21 are provided is not limited to the position between the protrusions accommodated in the groove part, and for example, the end face in the left-right direction of the raising / lowering shoji and the part of the frame body facing this end face Any part may be used as long as the raising / lowering shoddle and the frame face each other and contact when the raising / lowering shodder moves up and down.

Moreover, in the said embodiment, about the example in which the elastic protrusion part is provided in the guide member 20 which is provided in the support frame body 12 and makes the groove part, or the guide member 114 provided in the groove part 112a of the vertical shaft 112. It has been described, directly to the disabled children, may be provided, may be provided on both the shoji and the frame.

  In the above-described embodiment, an example in which two raising / lowering shojis are provided indoors and outdoors has been described. However, either one of them may be a raising / lowering window that is fixed and only the other can be raised and lowered. Absent.

  In the said embodiment, although the example in which the raising / lowering window was provided as an inner window provided in the room inner side of a glass louver window was demonstrated, it does not restrict to an inner window.

  Further, in the above-described embodiment, the lifting / lowering window that does not include the operation force reduction device using a mechanism such as a balancer has been described as an example. By using an elastic protrusion such as a mohair together with the body engaging part as in the above-described embodiment, it is possible to make the opening and closing upward more smoothly.

  In addition, as in the above-described embodiment, it is possible to improve the airtightness by providing an elastic protrusion such as mohair at a site where the frame of the shoji is engaged.

  In addition, the said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. The present invention can be changed and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof.
