Airtight parts and doors and windows

The present invention relates to an airtight member disposed between the frame body and the door sash in a door and window having a frame body and a door sash, and a door and window having the airtight member.

Conventionally, it has been known to provide an airtight member disposed between a frame body and a door sash in a frame body such as a window frame and a door and window of a door sash disposed in the frame body. The airtight member is mounted on, for example, the side of the window frame to ensure airtightness by abutting against the door sash.

However, it is known that, in the case where the airtight member is attached to the window frame, four airtight members are prepared according to each of the four frames of the upper frame, the lower frame, and the left and right vertical frames, and the airtight members are mounted on the airtight member. Each border. At this time, there is a problem that although the airtight members are brought into contact and the airtight wires are continuous, it is difficult to improve the airtightness due to the occurrence of seams.

Therefore, it is known that a continuous airtight member is circumferentially mounted on each of the four frames of the upper frame, the lower frame, and the left and right vertical frames (see Patent Document 1).

Patent Document 1 uses a plastic sash seal which is formed by integrally bonding a seal portion and a mounting portion, and the seal portion couples the lip portion to a pedestal provided parallel to the surface of the sash, and the above-described mounting The part is inserted into the groove of the window frame and has an arrow shape in cross section.

Patent Document 1: Japanese Utility Model Registration No. 2557595.

However, in the above-described Patent Document 1, a sealing portion is provided on the opposite side of the mounting portion with an arrow-shaped cross section, and the sealing portion is brought into contact with a frame or a frame disposed on the opposite side to ensure airtightness. Therefore, when the plastic sash sealing member is attached to the window frame so as to abut against the door sash from the outdoor side or the indoor side to ensure airtightness, it is necessary to follow the center line YY of the width direction of the base portion and the mounting portion. The window frame is arranged in the depth direction.

Therefore, when the plastic sash is bent by the seal at the corner portion of the window frame, the center line Y-Y in the width direction of the susceptor and the mounting portion becomes a bent neutral line. Therefore, there is a problem in that, by the aforementioned bending, one end side from the center line Y-Y to the width direction of the base is compressed, and The other end face side of the core line YY to the width direction of the base is elongated, and since the length between the end faces from the neutral wire to the width direction of the base is large, the seal is formed when the base is formed of a hard resin or the like. The bending requires a lot of force.

An object of the present invention is to provide an airtight member and a door and window which can be easily bent and can be disposed on a door and window in a continuous manner so as to improve airtightness.

The present invention provides an airtight member that is mounted in a mounting groove formed in a door and window, and includes: a main body portion made of a hard resin; and an adhesive portion composed of a soft resin, the main body portion including: a base portion The plate shape includes a front surface, a back surface facing the front surface, a side surface, and a connecting surface facing the side surface; and a mounting portion protruding from the back surface of the base portion and mounted in the mounting groove, the adhesion portion and the contact portion The connecting surface of the base portion is coupled to each other to have a hollow hollow tubular shape.

According to the invention, the airtight member is composed of a main body made of a hard resin and an adhesive portion made of a soft resin, and the close contact portion is connected to the connection surface of the base portion of the main body portion. Therefore, the close contact portion is disposed at the base portion. Side. Therefore, when the airtight member is attached to one of the window frame and the door sash, and the close contact portion is brought into contact with the other from the indoor/outdoor direction to ensure airtightness, the base portion and the close portion are arranged along the depth direction of the door and window. , the mounting part is from the base The portion is disposed so as to protrude in a direction orthogonal to the depth direction, for example, in the direction of the design surface.

Therefore, when the airtight member is disposed along the frame body such as the window frame and bent at the corner portion, the vertical line is bent along the depth direction of the door window, that is, along the front and back surfaces of the base portion. Therefore, the base portion can be bent in the height direction, that is, in the direction in which the thickness dimension is small. Therefore, if the attachment portion is cut along the width direction, the base portion and the adhesion portion can be easily bent, and the airtight member can be disposed along the corner portion of the frame body. As a result, since one airtight member can be disposed along the frame body, the joint between the airtight members can be reduced as compared with the case where the four airtight members are disposed, and the airtight performance can be easily improved.

Further, the close-contact portion has a hollow shape, and it is possible to prevent the close-contact portion from rising when the airtight member is bent, compared to the case where the close-contact portion has a fin shape. Therefore, it is possible to surely make the close contact portion and the movable door sash close to each other, and it is possible to prevent a gap from being formed in the close contact portion. Further, if the close-contact portion is erected, the close-contact portion and the movable door sash are always pressed, and this becomes a cause of an increase in the operating force when the movable door sash is opened and closed, and in the present invention, since the close portion does not stand up Therefore, it is also possible to prevent the airtight member from coming into contact with the movable door sash when opening and closing the movable door sash, thereby preventing an increase in the operating force.

In the airtight member of the present invention, the adhesion portion includes: a base end portion joined to the joint surface; and an upper sheet portion from a front side of the base end portion An end portion extending from an end portion on a back side of the base end portion; and a semicircular portion disposed between an edge of the upper sheet portion and the lower sheet portion, a center point of the semicircular portion The center line of the base portion is disposed on the end edge side of the lower piece portion at a distance from the front surface and the back surface.

According to the above configuration, when the center point of the semicircular portion coincides with the neutral line or when it is disposed closer to the end edge side of the upper portion than the neutral line, the adhesion portion can be made smaller from the front surface of the base portion. size. Therefore, when the airtight member is attached to the lower frame of the door and window that enters and exits, such as a floor window, the height difference from the base portion can be reduced, and the door and window corresponding to the barrier can be easily realized.

Further, in the close-contact portion, when the airtight member is bent, the volume on the side of the sheet portion on the compression side (inside of the corner) of the neutral line is reduced, and the volume on the side of the sheet portion on the side of the extension side (outside the corner) is increased. . Therefore, it is difficult to cause wrinkles or the like on the compression side and the extension side when the airtight member is bent. Therefore, it is possible to prevent pinholes (gap) from being generated in the bent portion of the airtight member and to lower the airtightness.

In the airtight member of the present invention, the adhesion portion includes: a base end portion that is joined to the joint surface; and a circular arc portion that is disposed between the end portion on the front side and the end portion on the back side of the base end portion The center point of the arc portion is disposed on a vertical line of the base portion that is equidistant from the front surface and the back surface.

According to the above configuration, the adhesion portion can be formed into a substantially cylindrical shape, and the size and volume required for the adhesion portion can be reduced. Therefore, the manufacturing cost of the airtight member can be reduced.

In the airtight member of the present invention, the first abutting portion is formed at an end portion on the side surface side of the back surface so as to protrude from the rear surface, and the end portion on the side of the connecting surface of the back surface is from the front surface A second abutting portion is formed to protrude, and a recess is formed between the mounting portion and the first abutting portion and between the mounting portion and the second abutting portion.

According to the above configuration, the first abutting portion and the second abutting portion are formed in the main body portion, and the abutting portions are formed in a recessed portion against the surface of the frame body, so that the base member is pressed by the base when the airtight member is attached to the frame body In the part, the mounting portion can be easily pressed into the groove.

Further, even if a tolerance is generated in the opening portion of the mounting groove, the opening portion faces the concave portion without coming into contact with the airtight member, so that the mounting portion can be easily pressed into a state in which the mounting groove is surely locked.

The invention provides a door and window, comprising: a frame body; a movable door sash, which is arranged to be movable relative to the frame body; and the airtight member; in the frame body, facing the opening blocked by the movable door sash a mounting groove for mounting the aforementioned airtight member is formed on the inner peripheral surface thereof, In the airtight member, the mounting portion is attached to the mounting groove, and the mounting portion located at a corner portion of the frame body is cut.

According to the present invention, since the airtight structure can be formed by one airtight member, the airtightness of the door and window can be easily improved as compared with the case of using four airtight members.

According to the airtight member and the door and window of the present invention, the airtight member can be easily bent, and the airtight member can be disposed on the door and window in a continuous manner around the door, thereby improving airtightness.

The front surface 261B facing the mounting grooves 211 and 252, the side surface 261C facing the outdoor side, and the connecting surface 261D facing the side surface 261C. Therefore, the connection surface 261D is disposed to face the indoor side, and the adhesion portion 270 is formed to be connected to the connection surface 261D.

Further, in the following description, the direction in which the airtight member 26 extends, that is, the longitudinal direction of the upper frame 21, the lower frame 22, the vertical frame 23, and the intermediate frame 25 is defined as the longitudinal direction of the airtight member 26. In addition, it will be in the airtight member 26 When the mounting groove 211 and the mounting groove 252 are mounted, the direction along the depth direction of the window frame 2, that is, the direction orthogonal to the side surface 261C and the connecting surface 261D is defined as the width direction. Further, when the airtight member 26 is mounted in the mounting groove 211 and the mounting groove 252, the outer surface of the upper frame 21, the lower frame 22, the vertical frame 23, and the middle frame 25, that is, the direction orthogonal to the front surface 261A and the rear surface 261B. The direction of the height of the airtight member 26 is defined as the lower direction in the height direction toward the bottom surface of the mounting grooves 211, 252, and the opposite direction of the lower side is defined as the upper side.

At the end on the side surface 261C side of the back surface 261B of the base portion 261, the first contact portion 262A is formed to protrude downward from the back surface 261B, and the end portion of the back surface 261B of the base portion 261 on the side of the connection surface 261D. In the vicinity, the second abutting portion 262B is formed to protrude from the back surface 261B toward the lower side. Therefore, a recess 263 that is recessed toward the front surface 261A side (the upper side) is formed between the first abutting portion 262A, the second abutting portion 262B, and the mounting portion 265.

The mounting portion 265 is formed to protrude downward from the back surface 261B of the base portion 261 and is formed continuously along the longitudinal direction of the base portion 261.

The mounting portion 265 includes an insertion portion 266 that is connected to the back surface 261B and inserted into the mounting grooves 211 and 252, and a protruding portion 267 that extends downward from the insertion portion 266, and has a width dimension smaller than the width direction. The insertion portion 266 and the locking piece portion 268 are extended from the front end of the protruding portion 267 toward the first abutting portion 262A side and the second abutting portion 262B, respectively. Stretch. The locking piece portion 268 extends in a direction substantially at an angle of 30 to 35 degrees with respect to the protruding portion 267.

The insertion portion 266 extends downward in the height direction from the first abutting portion 262A and the second abutting portion 262B. In other words, the position of the insertion portion 266 and the step portion 266A of the protruding portion 267 in the height direction is located below the first abutting portion 262A and the second abutting portion 262B.

The position in the width direction of the end edge portion 268A of each of the locking piece portions 268 is located between the insertion portion 266 and the first abutting portion 262A and between the insertion portion 266 and the second abutting portion 262B. Further, the position of the end edge portion 268A of each of the locking piece portions 268 in the height direction is located below the insertion portion 266.

The adhesion portion 270 is formed to be continuous with the connection surface 261D side of the base portion 261. The close joint portion 270 has a hollow tubular shape having a hollow structure. In other words, the adhesion portion 270 includes a base end portion 271 joined to the joint surface 261D, an upper portion 272 extending obliquely upward from the upper end portion of the base end portion 271, and an obliquely downward extending portion from the lower end portion of the base end portion 271. The sheet portion 273 and a semicircular portion 274 disposed between the end edge of the upper sheet portion 272 and the end edge of the lower sheet portion 273.

In the airtight member 26 of the present embodiment, the angle θ1 between the surface of the upper piece portion 272 and the direction of the design surface along the joint surface 261D is 75 degrees, that is, the angle with respect to the depth direction along the front surface 261A is 90. Degree - θ1 = 15 degrees. In addition, the surface of the lower piece portion 273 and along the joint surface 261D The angle θ2 between the orientations of the design faces is 45 degrees.

Therefore, in the adhesion portion 270, one of the upper piece portion 272 and the semicircular portion 274 is disposed above the height position of the front surface 261A of the base portion 261. Further, the center point O of the semicircular portion 274 is located below the center line L1 passing through the center in the height direction of the base portion 261. Therefore, in the close contact portion 270, the volume of the portion located on the upper side of the neutral line L1 (the opening side of the window frame 2) is smaller than the volume of the portion located on the lower side of the neutral line L1.

Next, a mounting structure in which the airtight member 26 is mounted in the mounting grooves 211, 252 will be described based on an example in which the airtight member 26 is mounted in the mounting groove 211 of the lower bezel 22.

As shown in FIG. 5, the groove 211 is attached to the lower frame 22 so as to be open on the upper surface of the outdoor appearance sheet portion 210. In other words, the attachment groove 211 includes a rising piece portion 215 facing the indoor side of the outdoor appearance sheet portion 210, a bottom surface portion 216 extending from the intermediate portion in the height direction of the rising piece portion 215 toward the outdoor side, and the bottom surface portion 216. The side portion 217 extending upward is divided. The upper end of the side surface portion 217 is connected to the upper surface portion 212 of the outdoor appearance sheet portion 210 by a step portion. Therefore, the upper surface of the raised piece portion 215 and the side surface portion 217 of the base portion 261 on which the airtight member 26 is placed is formed at a position slightly lower than the upper surface portion 212. In this state, the front surface 261A of the base portion 261 and the surface of the lower frame covering member 50 placed on the upper surface portion 212 are almost at the same level.

At the upper end portions of the rising piece portion 215 and the side surface portion 217, locking projections 213 projecting toward each other are formed. Therefore, the width of the opening of the mounting groove 211 is set smaller than the width dimension of the inside of the mounting groove 211. The width dimension between the locking projections 213 is set to a size that can press the mounting portion 265 when the airtight member 26 is mounted.

The height of the locking projection 213 is set to be equal to or slightly smaller than the dimension of the first abutting portion 262A, the second abutting portion 262B, and the end edge portion 268A in the height direction. Further, the corner portion 213A on the upper surface side of the locking projection 213 has an arc shape.

In addition, the mounting grooves 211 of the upper frame 21 and the vertical frame 23 have the same structure, and the mounting groove 252 of the middle frame 25 has the same structure in that the opening portions of the mounting groove 252 are formed with locking projections close to each other. .

The airtight member 26 is mounted in the mounting grooves 211, 252 as described above in the following steps.

As shown in FIG. 6, the airtight member 26 is bent in the window frame 2 at the corner portions where the upper frame 21, the lower frame 22, the vertical frame 23, and the middle frame 25 are joined. A portion of the attachment portion 265 of the airtight member 26 corresponding to the position of the bent portion is cut in advance along the width direction of the attachment portion 265. So in the window frame 2 In the corner portion, only the base portion 261 and the close portion 270 are continuous in the airtight member 26.

Next, the airtight member 26 is sequentially mounted to the upper frame 21, the lower frame 22, the vertical frame 23, the mounting groove 211 of the middle frame 25, and the mounting groove 252. Specifically, the mounting portion 265 of the airtight member 26 is pressed between the mounting groove 211 and the locking projection 213 of the mounting groove 252. Then, the locking piece portion 268 which is inclined from the front end portion of the protruding portion 267 is guided by the corner portion 213A and pressed toward the protruding portion 267 side so as to be able to pass between the locking projections 213.

In this state, when the base portion 261 is further pressed toward the mounting grooves 211 and 252, the first abutting portion 262A and the second abutting portion 262B abut the upper surfaces of the rising piece portion 215 and the side surface portion 217. . At this time, since the concave portion 263 is formed, only the first abutting portion 262A and the second abutting portion 262B are in contact with the upper surfaces of the rising piece portion 215 and the side surface portion 217. Therefore, when the base portion 261 is further pushed in, the center portion in the width direction of the base portion 261 is deflected downward, and the attachment portion 265 is also moved downward. Therefore, the locking piece portion 268 also passes between the locking projections 213 and expands to the original state.

Then, when the press-fitting of the base portion 261 is released, the bent base portion 261 returns to the original state, and the edge portion 268A of the locking piece portion 268 abuts against the lower surface of the locking projection 213, and the airtight member 26 It is locked in the mounting grooves 211, 252.

In addition, since the adhesion portion 270 is below the sheet portion 273 and along the joint surface The angle θ2 between the vertical faces of 261D is large to 45 degrees, and the lower portion 273 can be disposed so as not to hit the riser portion 215.

Further, as shown in FIG. 6, in the airtight member 26, the portion corresponding to the corner portion of the window frame 2 is the cutting portion 265A obtained by cutting the mounting portion 265 in the width direction as described above, and only the base portion 261 and The adhesion portion 270 is continuous. Therefore, as shown in FIG. 6, the thin plate-shaped base portion 261 can be bent in the height direction, that is, the direction in which the thickness dimension is small, and can be easily bent. Further, the close contact portion 270 has a tubular shape and is bent in the cross-sectional direction of the tube, so that it can be easily bent. Therefore, the airtight member 26 can be easily and surely bent along the corner portion of the window frame 2.

Then, the airtight member 26 is attached to all of the mounting grooves 211, 252 of the upper bezel 21, the lower bezel 22, the vertical bezel 23, and the middle frame 25, whereby the installation work of the airtight member 26 is completed. Further, the end faces in the longitudinal direction of one airtight member 26 abut each other at a portion such as a central portion in the left-right direction of the upper bezel 21 that does not affect airtightness.

When the inner door sash 4 is moved during the opening and closing process, as shown in FIG. 5, since the inner door sash 4 is located on the outdoor side and is separated from the airtight member 26, the airtight member 26 does not move when the inner door sash 4 moves. The inner door sash 4 is pressed against the inner door sash 4, and the inner door sash 4 can be moved with a light operating force.

And moving the inner door sash 4 to the closed position by the handle When the operation of pulling the inner door sash 4 toward the outdoor side is performed, as shown in FIG. 8, the inner door sash 4 is pressed against the close contact portion 270 of the airtight member 26 to press the close contact portion 270. Thereby, the airtight member 26 can be in close contact with the inner door sash 4, and airtightness can be improved.

(Effect of this embodiment)

(1) In the present embodiment, the airtight member 26 is composed of a main body portion 260 made of a hard resin and an adhesive portion 270 made of a soft resin, and the adhesion portion 270 is provided to be connected to the side surface side of the base portion 261 of the main body portion 260. Therefore, when the airtight member 26 is disposed along the window frame 2 and bent at the corner portion, the neutral line is set along the front surface 261A and the back surface 261B of the base portion 261, and the base portion 261 can be along the height direction. That is, the direction in which the thickness is small is bent. Therefore, if the attachment portion 265 is cut along the width direction, the base portion 261 and the adhesion portion 270 can be easily bent, and the airtight member 26 can be easily disposed along the corner portion of the window frame 2. Thereby, since one airtight member 26 can be arrange|positioned along the window frame 2, compared with the case where four airtight members are arrange|positioned, the joint of the airtight member is reduced, and airtightness can be improved.

(2) In the adhesion portion 270, the volume on the side of the sheet portion 272 on the compression side (inside of the corner) of the neutral line when the airtight member 26 is bent is reduced, and the sheet on the side of the extension side (outside the corner) is increased. Since the volume of the portion 273 is small, it is possible to suppress wrinkles or the like on the compression side and the extension side when the airtight member 26 is bent. Therefore, it is possible to prevent a gap (pinhole) from being generated in the bent portion of the airtight member 26 and to lower the airtightness.

(3) Since the adhesion portion 270 has a hollow shape, it is possible to prevent the adhesion portion 270 from being erected when the airtight member 26 is bent, compared to the case where the adhesion portion 270 has a fin shape. Therefore, the adhesion portion 270 is surely in close contact with the inner door sash 4, and it is possible to prevent a gap from being formed in the close contact portion. Further, if the close-contact portion 270 is erected, the close-contact portion 270 and the inner door sash 4 are always pressed together, and at this time, the operation force required to open and close the inner door sash 4 is increased, and in the present embodiment, the close-contact portion is Since the 270 is not erected, it is possible to prevent contact with the airtight member 26 when opening and closing the inner door sash 4, and it is possible to prevent an increase in the required operating force.

(4) The inclination angle (90 degrees - θ1) of the upper piece portion 272 of the close contact portion 270 of the airtight member 26 with respect to the front surface 261A can be made small, and the height from the extension line of the front surface 261A to the upper end portion of the adhesion portion 270 converges to, for example, 1 mm. Left and right, according to the barrier-free standard can be regarded as the size without steps. Therefore, the upper surface of the lower frame 22 can be formed into a stepless structure on an unobstructed basis, and when the window frame 2 is used for a balcony window, the movement of a person or a wheelchair can be smoothly performed.

Further, in the present embodiment, the cover member 50 for the lower frame is attached to the lower frame 22, but the surface of the cover member 50 for the lower frame and the surface of the base portion 261 of the airtight member 26 are almost at the same height level. The steps enable a barrier-free structure.

Further, since the protruding portion of the portion of the adhesion portion 270 that protrudes beyond the surface of the base portion 261 is small, even if the person entering or leaving the lower frame 22 or the wheelchair steps on the adhesion portion 270, the adhesion portion 270 can be prevented from being damaged.

(5) The first abutting portion 262A and the second abutting portion 262B are formed in the main body portion 260, and only the surfaces of the abutting portions 262A, 262B and the upper bezel 21, the lower bezel 22, the vertical bezel 23, and the middle frame 25 are formed. Since the concave portion 263 is formed in abutting manner, when the airtight member 26 is attached, the mounting portion 265 can be easily pressed into the inside of the mounting grooves 211 and 252 by pressing the base portion 261.

Further, even if a tolerance is generated in the corner portion 213A of the locking projection 213 of the opening portion of the mounting grooves 211, 252, since the corner portion 213A faces the concave portion 263 without coming into contact with the airtight member 26, it can be surely pressed into the end edge portion. 268A is in a state of being in contact with the lower surface of the locking projection 213 to be locked.

(6) The position in the depth direction of the close contact portion 270 in the window frame 2 can be set according to the position at which the mounting grooves 211 and 252 are formed, and is not affected by the amount of press-fitting of the airtight member 26 into the groove. Therefore, the position of the close contact portion 270 can be accurately and stably set, and the entire circumference of the airtight member 26 can be accurately set to be in close contact with the closed inner door sash 4 and between the sliding inner door sash 4 Separate size.

(7) The close contact portion 270 of the airtight member 26 has a hollow shape, so that it can be increased in contrast to the fin-shaped airtight member when pressed by the inner door sash 4 elastic force. Therefore, the adhesion between the close contact portion 270 and the inner door sash 4 is also increased, and at this point, the airtightness can also be improved.

In particular, in the present embodiment, since the linear portion of the upper piece portion 272 and the lower piece portion 273 is provided, the repulsive force of the adhesion portion 270 can be further increased.

(8) Since the attachment portion 265 of the airtight member 26 is formed in a solid state made of a hard resin, the mounting strength of the attachment portion 265 with respect to the attachment grooves 211 and 252 can be improved as compared with the case where the hollow portion is formed in the attachment portion 265. Therefore, it is also possible to prevent the airtight member 26 installed in the mounting grooves 211, 252 from coming off.

[Modification]

The present invention is not limited to the configurations described in the above embodiments, and modifications within the scope of the object of the present invention are included in the present invention.

For example, as shown in FIG. 9, an airtight member 26A having an annular portion 270A having a substantially circular cross section and a close portion may be used. In other words, the adhesion portion 270A includes a base end portion 271A joined to the connection surface 261D of the base portion 261, and a circular arc portion 274A disposed between the front end portion and the back side end portion of the base end portion 271A. Further, the center point O of the circular arc portion 274A is located on the vertical line L1 of the base portion 261.

In this case, since it is not necessary to provide the upper piece portion 272 and the lower piece portion 273, the design of the adhesion portion 270A is facilitated, and the size and volume of the adhesion portion 270A can be reduced. Therefore, the manufacturing cost of the airtight member 26A can be reduced. However, since the protruding portion 270A has a larger protruding dimension from the front surface of the base portion 261 than the airtight member 26 of the above-described embodiment, the airtight member 26A is preferably used for a window other than the balcony window that requires an unobstructed correspondence.

The shape of the adhesion portion in the airtight member 26 is not limited to the adhesion portion 270 of the above-described embodiment and the adhesion portion 270A of the modification. For example, an arc portion that is longer than a semicircle may be disposed between the end edges of the upper piece portion 272 and the lower piece portion 273. Further, the close contact portion may be composed of a plurality of arc portions having different curvatures. That is, as the close contact portion, it may have a hollow tubular shape having a hollow portion.

Further, the configuration of the attachment portion 265 may be appropriately set in accordance with the shape of the groove portion of the window frame 2 to be attached, or the like.

The airtight member and the door and window of the present invention are not limited to the single sliding window 1 of the above-described embodiment, and can be applied to various windows such as various sliding windows such as an upper sliding window, a rotating window such as an inner opening window or a vertical sliding window.
