Description

  The present invention relates to a sash including a shoji that moves on a rail to open and close, and more particularly, to a sash having improved airtightness.

  Normally used pulling, single pulling (single door) sashes are two (or more) shojis (doors) that move horizontally on two (or more) straight rails horizontally. It is configured to open and close, and is currently used in many buildings, and has become mainstream as a fitting provided in the opening of the outer wall. Such a sash that moves on a straight rail is based on the premise that rain and wind will not enter when the shoji is closed, blocking the inside and outside of the building. Airtightness cannot be expected. In recent years, high airtightness and high heat insulation have become important issues for houses and the like from the viewpoint of energy saving, and sashes are also required to have high airtightness and high heat insulation.

Various means have been studied as a means for increasing the airtightness of the sash. For example, Japanese Patent Application Laid-Open No. 2000-337042 (Patent Document 1) discloses a rubber for airtightness against a door contact surface portion of a window frame when closed. Formed so that the surfaces on the back side of the scab portion of the window body are in close contact with each other through a material, and the structure further enhances the airtightness as the external pressure received by the window body increases, and further moves the window body forward For this reason, a sash has been proposed in which a curved rail portion is provided on the guide rail so that the hood portion of the window main body is brought into close contact with the guide rail so as to improve airtightness.

JP 2000-337042 A

The sash normally used is provided with a door wheel at the lower end of the sash portion of the shoji to move the window main body on the straight rail to the left and right. However, the sash shown in Patent Document 1 is brought into close contact by moving the window main body forward by the curved rail portion of the guide rail and pressing the window main body. A large lateral pressure is applied from the lateral direction. As a result, excessive stress is applied to the door roller and the guide rail, so that the deterioration occurs and deforms in a short period of time. Will occur. Further, since the window main body generally has a weight of about several tens of kilograms to one hundred kilograms, when the door wheel is run on the curved rail portion provided with the guide rail, it is excessive due to the weight of the window main body. Since a large inertial force is applied to the door, excessive stress is applied to the door and the guide rail, and there arises a problem that the airtightness is lost due to deterioration and deformation.

  The problem to be solved by the present invention is that not only high airtightness and high heat insulation can be obtained, but also the stress applied to the door wheel and rail can be reduced, and even a heavy shoji can be opened lightly. It is to provide a sash that can.

Therefore, the sash according to the present invention includes a shoji that moves on a rail provided on a window frame to open and close, and one of the lower and lower arm of the shoji has a door to both sides of the shoji in the moving direction. Are disposed on both sides of the shoji in the thickness direction of the shoji, and on the lower frame, two rails for guiding the pair of doors are respectively moved in the moving direction. The two rails are formed with a high portion raised with respect to the lower frame at the position of the door wheel in a state in which the shoji is closed. Slopes which are gradually lowered toward the opening direction are formed, and airtight members are respectively disposed between the lower frame and the upper frame of the shoji and the window frame, and in a state where the shoji is closed, The shoji is pushed upward by the high part, and the airtight member is It is summarized in that for pressing the window frame.

Moreover, it is preferable that the rail is set to a length from a position of the door pulley in a state where the shoji is closed to a position of the door wheel in a state where the shoji is opened.

  Further, it is desirable that the airtight member is made of rubber or synthetic resin having elasticity and lubricity, and is disposed with the same length as the width in the moving direction of the shoji.

  According to the present invention, by forming the high portion on the two rails, in a state where the shoji is closed, the pair of door wheels disposed on the lower arm are guided to the high portion of the rail and push the shoji upward. Therefore, since the airtight member disposed on the shoji is pressed against the window frame, high airtightness and high heat insulation necessary as a sash can be obtained. At this time, the door cart is moved up and down by the high part of the two rails, and the load is the same as that of a sash that is normally used, and no excessive stress due to side pressure is applied to the door wheel and the guide rail. -Long life while maintaining high heat insulation.

  In addition, the two rails are formed with a high portion at the position of the door wheel when the shoji is closed, so that when the shoji is opened from the closed state, the shoji can move from the high portion to the slope. Since it falls, even a heavy weight shoji can be easily opened with a small force.

  Furthermore, if the length of the rail is set from the position of the door pulley with the shoji closed to the position of the door with the shoji open, the gap between the rail end and the window frame is opened, so two It is possible to easily remove dust and the like that has entered between the rails, and to improve convenience for the user.

It is a front view which shows the Example of the sash by this invention. It is a sectional side view of the sash shown in FIG. It is a perspective view of the sash shown in FIG. (A) (B) is explanatory drawing which shows the open / close state of a sash. It is sectional drawing which shows the modification of the airtight member in the sash of this invention.

  The sash according to the present invention includes a shoji that moves on a rail provided on a window frame and opens and closes, and one of the shojis or the lower arm of the shoji is provided with a door on each side of the shoji. The door is disposed on both sides of the shoji in the thickness direction of the shoji, and two rails for guiding the pair of doors are parallel to the moving direction on the lower frame. The two rails are formed with a height portion that is higher than the other rail portions at a position corresponding to the door roller in a state in which the shoji is closed, and the shoji is placed from the height portion. Slopes which are gradually lowered toward the opening direction are formed, and airtight members are respectively disposed between the lower frame and the upper frame of the shoji and the window frame, and in a state where the shoji is closed, The above-mentioned shoji is pulled upward by a high part, and the above-mentioned airtight member To be pressed against the window frame.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 to 3 show an embodiment of a sash according to the present invention. The illustrated sash is exemplified by a wooden sash, and is a sliding door type sash composed of a window frame 1 made of wood and two shojis 2 formed of wood. Although the window frame 1 is formed in a long rectangle and is made of wood as a whole, the outer lower frame 1a on the left outer side on the left side in the drawing is made of aluminum. This is intended to ensure strength or prevent corrosion, but may be replaced with wood.

  A step is provided between the outer lower frame 1a and the inner lower frame 1b of the window frame 1, and the outer lower frame 1a is formed low. Two rails 3 are provided on the upper surfaces of the outer lower frame 1a and the inner lower frame 1b. The two rails 3 are provided in a straight line parallel to the moving direction of the two door wheels 4 respectively disposed on both sides of the moving direction of the shoji 2 described later. And as shown in FIG.1 and FIG.3, the height part 3a is formed in the position corresponding to the position of the door pulley 4 of the state in which the shoji 2 was closed. As shown in FIG. 1, the height portion 3 a is higher than the other rail portions by a height h, and the shoji 2 is located in the section W between the height portion 3 a and the other rail portions. A slope 3b that is gradually lowered toward the opening direction is formed. The height h of the height portion 3a is appropriately set in relation to the airtight members 5 and 6 described later, but may be about 3 mm to 10 mm.

The two rails 3 are set to have a dimension L that is slightly longer than the length of the position of the door pulley 4 from the position of the door roller 4 with the shoji 2 closed to the state with the door 2 fully opened. Thereby, the length of the rail 3 becomes shorter than the inner width dimension of the outer lower frame 1a and the inner lower frame 1b of the window frame 1, and the end portion of the rail 3 and the inner surface of the window frame 1 are separated. For this reason, the space between the end of the rail 3 and the inside of the window frame 1 is opened. For example, when dust or the like enters between the two rails 3, dust or the like can be easily removed from the opened portion, and convenience for the user can be improved. The two rails 3 are configured similarly except that the rail 3 provided on the upper surface of the inner lower frame 1b is provided on the opposite side, and the dimensions of the rails 3 are the same. L is set in the same manner.

The rail 3 is formed on the upper surface of the outer lower frame 1a and the inner lower frame 1b by forming a high portion 3a or the like by bending a square bar made of, for example, aluminum. Note that the rail 3 may be formed of a metal material having a rust prevention effect such as stainless steel, or a synthetic resin or wood.

  On the other hand, the shoji 2 has a double-glazed glass 2b mounted on a frame 2a made of wood or aluminum in the same manner as a well-known sash shoji. As shown in FIG. 1, one door wheel 4 is disposed on each side of the shoji 2 in the moving direction on the lower arm 2 c of the shoji 2. Further, as shown in FIG. 2, these door carts 4 are respectively arranged on one side and the other side in the thickness direction of the shoji 2 according to the two rails 3 described above. Thus, the shoji 2 is guided by the two rails 3 on the lower side 2c side, and further, is guided by the guide groove 1e formed on the inner surface of the window frame 1 by the plate member 2e fixed to the end surface on the upper side 2d side. Move by. In addition, the depth of the guide groove 1e is formed deeper than the width dimension of the plate member 2e, and is configured to allow the vertical movement of the shoji 2 to be permitted.

  Further, an airtight member 5 is disposed on the lower arm 2 c of the shoji 2. The airtight member 5 is formed in a plate shape as shown in FIG. 2, and protrudes in the direction perpendicular to the side surface of the lower collar 2c toward the indoor direction on the right side of the figure. The length of the airtight member 5 is set substantially equal to the lateral width of the shoji 2, and the projecting dimension of the airtight member 5 is a recess 1c formed in the lower frames 1a and 1b of the window frame 1, as shown in FIG. The length to be inserted into 1d is set. In the state where the shoji 2 is opened, as shown in the drawing, the front end side of the airtight member 5 is set to be slightly separated from the upper surface of the recesses 1c, 1d, and in the state where the shoji 2 is closed, the recesses 1c, 1d. It is set so that the front end side of the airtight member 5 is in pressure contact with the upper surface of the. The airtight member 5 is preferably selected from a rubber or synthetic resin having elasticity and flexibility, and a material having wear resistance and lubricity.

  Further, an airtight member 6 is disposed on the inner surface of the window frame 1 located above the upper collar 2d. As shown in FIG. 2, the airtight member 6 is formed in a tube shape made of rubber or synthetic resin having elasticity and flexibility, and a projecting piece portion projecting integrally from the outer periphery in the radial direction is formed on the inner surface of the window frame 1. It is fitted and fixed in the formed groove. The airtight member 6 is set to a length substantially equal to the lateral width of the shoji 2. In the state where the shoji 2 is opened, as shown in the figure, the airtight member 6 is set to be slightly separated from the upper surface of the upper heel 2d. In the state where the shoji 2 is closed, the airtight member 6 is disposed on the upper surface of the upper heel 2d. Is set to be in pressure contact.

  Next, the operation of the sash according to the present invention will be described. The shoji 2 has a pair of door wheels 4 disposed on the lower ridge 2c guided by the two rails 3 and the upper ridge 2d is guided by a guide groove 1e having a plate member 2e formed on the inner surface of the window frame 1. Moving. As shown in FIG. 4A, in the state in which the shoji 2 is opened, the airtight member 5 disposed in the lower arm 2c is slightly separated from the recesses 1c and 1d and disposed on the inner surface of the window frame 1. The airtight member 6 is separated from the upper surface of the upper collar 2d.

  When the shoji 2 is moved toward the vertical frame 1c of the window frame 1 from the state in which the shoji 2 is opened, the door 4 moves up the slope 3b while being guided by the two rails 3, and the shoji 2 is gradually moved upward in the figure. And eventually reach the high part 3a. When the shoji 2 is pushed up and lifted in this way, as shown in FIG. 4 (B), the distal end side of the airtight member 5 disposed on the lower collar 2c comes into pressure contact with the upper surfaces of the recesses 1c and 1d. Further, the airtight member 6 disposed on the inner surface of the window frame 1 is in pressure contact with the upper surface of the upper collar 2d. As a result, the outer side and the inner side of the sash are blocked by the airtight member 5 and the airtight member 6.

  At this time, the door carts 4 are respectively disposed on both sides in the moving direction, the two rails 3 for guiding the door carts 4 are provided in parallel, and the door cart 4 is in a position where the shoji 2 is closed. Since the high part 3a is formed, the shoji 2 moves in parallel without tilting. As described above, the shoji 2 is pushed up by the high portion 3a, and the lower heel 2c side and the upper heel 2d side of the shoji 2 are made airtight by the airtight member 5 and the airtight member 6. Also, between the window frame 1 and the vertical frame 1c, an airtight member (not shown) is arranged to block the outside and the inside of the sash in the same manner as a general sash.

  On the other hand, when the shoji 2 is opened from the closed state, the door 4 of the shoji 2 is guided by the two rails 3 and moved in the direction opposite to the closing direction described above. At this time, since the pair of door rollers 4 descends the slope 3b from the high place 3a, the shoji 2 descends due to gravity, so that even if the weight of the shoji 2 is several tens of kg or more, it can be opened lightly.

  FIG. 5 shows a modification of the hermetic member in the sash of the present invention. The difference from the above-described embodiment is that the airtight member 10 is disposed on the upper surface side of the upper collar 2d. That is, as shown in FIG. 2, the airtight member 6 has a protruding piece portion that protrudes integrally from the outer periphery in the radial direction and is fitted and fixed to a groove formed on the upper surface of the upper collar 2 d. The airtight member 10 is formed in a tube shape made of rubber or synthetic resin having elasticity and flexibility, like the airtight member 6 described above, and the length is set to be substantially equal to the lateral width of the shoji 2. Further, when the shoji 2 is opened, the airtight member 10 is set to be slightly separated from the inner surface of the window frame 1, and when the shoji 2 is closed, the airtight member 10 is pressed against the inner surface of the window frame 1. It is set.

  On the other hand, the airtight member 11 disposed on the lower arm 2c of the shoji 2 is substantially the same as the airtight member 5 described above. However, as shown in FIG. In a state where the shoji 2 is closed by being inserted into the recesses 1c and 1d formed in the lower frames 1a and 1b of the window frame 1, the front end side of the airtight member 5 is pressed against the upper surfaces of the recesses 1c and 1d. By adopting such a shape, the airtightness can be further improved. The airtight member 11 is also preferably selected from a rubber or synthetic resin having elasticity and flexibility, and a material having wear resistance and lubricity.

  Although the embodiment described above exemplifies the sliding sash, it can also be applied to a one-way (single door) sash or a suspension door sash. In the case of a one-way sash, there is only one shoji to be opened and closed, a door is provided like the shoji described above for this one shoji, two rails are provided on the lower frame of the window frame, By providing the airtight member, a highly airtight and highly heat-insulating sash can be obtained in the same manner as in the above-described embodiment.

Further, in the case of a hanging door, contrary to the sash described above, a rail is provided on the upper part to suspend the hanging door. For this reason, on the upper side of the upper lid of one suspension door, one suspension door cart is arranged on each side in the moving direction, and the suspension door cart is placed at the corresponding position on one side and the other side in the thickness direction of the shoji. Each is arranged. On the other hand, the two upper rails are provided with a high portion at a position corresponding to the suspension door with the suspension door closed, similarly to the rail described above. And in the position which closed the suspension door pulley, the suspension door is pushed up by the high part of an upper rail. Thus, an airtight member is provided on the upper side of the upper lid of the suspension door or on the inside of the window frame facing the upper lid, and the airtight member is provided on one of the lower lid of the suspension door and the lower frame of the window frame. Therefore, the upper and lower airtight members are pressed against the window frame by pushing up the suspension door by the high portion. For this reason, airtightness and heat insulation can be obtained like the sash mentioned above.

Furthermore, in the case of a raising / lowering window, since the shoji is moved up and down, it can be similarly applied by adopting a configuration in which the relationship between the window frame and the shoji is rotated 90 degrees. That is, inside the vertical frame of the window frame, two rails having a high portion are disposed in the same manner as in the above-described embodiment, and the vertical arm of the shoji that moves up and down is the same as in the above-described embodiment. In addition, one door cart is arranged on each side of the moving direction of the shoji, and these door carts are respectively arranged on one side and the other side in the thickness direction of the shoji according to the two rails. In the state where the shoji is lowered and closed by providing a member and press-contacting it, the shoji is pushed laterally by the high part of the two rails, and as in the above-described embodiment, it is highly airtight and highly insulated. You can get a sash.

Although the present invention has been specifically described above based on the embodiments, it is needless to say that the present invention is not limited to the above embodiments and can be variously modified without departing from the gist thereof. The shape of the shoji, window frame, etc. is an example, and it may be modified to match the type and shape of the sliding door used. Further, although two rails are provided on the window frame and two doors are provided on the shoji, a door and a rail for guiding the door may be added according to the weight of the shoji. Furthermore, although the said Example illustrated the rotary wheel type as a door pulley, when a shoji is lightweight, you may replace with a sliding type thing.

The present invention is applied to the field of architecture such as houses, the field of transportation such as automobiles, vehicles, ships, and aircraft, and the field of equipment such as freezers, freezer showcases, and temperature and humidity chambers.
