Description

  The present invention relates to a raising / lowering window provided in an opening of a building such as a house or a public facility. More specifically, the present invention relates to a raising / lowering window in which a fixed shodder and a movable shoddle are juxtaposed in the same plane in a closed posture and can be easily opened and closed.

  Many of the opening devices provided in the opening of a building include a frame attached along an edge of the opening and a shoji provided inside the frame. In such an opening device, there is a raising / lowering window that allows the opening to be closed / opened by a movable shoddle movable up and down. Conventionally, most of the raising and lowering windows are provided with inner and outer shojis that are shifted in the expected direction, and at least one of them is raised and lowered to enable closing / opening of the opening.

  However, the raising and lowering windows provided with the inner and outer shojis shifted in the expected direction have problems such as poor airtightness. Therefore, a raising / lowering window having two shojis juxtaposed in the same plane in a closed posture has been considered. For example, Patent Document 1 includes a fixed shoji (fitting kill portion) provided at the lower part inside the frame body and a movable shoji (up / down shoji) provided at the upper part inside the frame body in a closed posture, and is in a closed posture. Discloses a raising / lowering window in which a stationary screen and a movable screen are juxtaposed in the same plane.

JP-A-8-296362

  As described above, for the purpose of improving airtightness and the like, several raising and lowering windows in which two shoji screens are juxtaposed in the same plane in a closed posture have been proposed so far. Many conventional techniques related to such raising and lowering windows have been based on the premise that a shoji equipped with a single glass plate is used, and the movable shoji is raised and lowered only by human power. However, in recent years, it has become common to use shoji screens with double-glazed glass for the raising and lowering windows in consideration of improvements in heat insulation, etc. It takes great power to raise and lower.

  Moreover, in the above-mentioned Patent Document 1, there is proposed a raising / lowering window that includes two shojis juxtaposed in the same plane in a closed posture and can easily raise and lower the shoji using a balancer. In the raising and lowering window, the shoji is moving vertically up and down linearly, and a link mechanism for moving the shoji almost horizontally in the expected direction is attached to the lower part of the shoji. However, in this form, the number of parts increases and the cost increases. Further, there is a problem that a space required for installing the raising / lowering window is increased.

  Accordingly, an object of the present invention is to provide a raising / lowering window that has a simple structure, can be easily opened and closed, and is excellent in airtightness.

FIG. 6B is a posture locked by the locking device 37. FIG. FIG. 1 and 2, the back side of the paper is the outdoor side, and the front side of the paper is the indoor side. In FIGS. 3 to 5, the left side of the paper is the outdoor side, and the right side of the paper is the indoor side. The upper side is the outdoor side, and the lower side of the page is the indoor side.

  In the following, the “finding direction” means the direction along the flat plane of the raising and lowering window that is flat as a whole, and in the posture in which the raising and lowering window is attached to the building, It means the direction along. Further, “inside the direction of finding” means the center direction of the raising / lowering window in the direction of finding. Accordingly, “outward in the direction of finding” means a direction away from the opening in the direction of finding. Furthermore, the “prospective direction” means the thickness direction of the flat window having a flat plate shape as a whole, and indicates the indoor / outdoor direction of the building when the lift window is attached to the building.

  As shown in FIG. 1, the raising / lowering window 100 includes a frame body 10 attached along the edge of the building opening, and a fixed screen 20 and a movable screen 30 attached to the inside of the frame 10. As shown in FIG. 2, balancers 60 and 60 are provided in the vertical frames 13 and 14.

  The frame 10 includes an upper frame 11 and a lower frame 12 which are long members arranged in the horizontal direction, and a left vertical frame 13 which is a long member provided across the ends of the upper frame 11 and the lower frame 12 and And a right vertical frame 14.

  Further, a guide groove 40 is formed in the right vertical frame 14 as indicated by a broken line in FIG. Although not shown, the left vertical frame 13 is also formed with a guide groove similar to the right vertical frame 14. The configuration of the guide groove 40 will be described in detail later.

  The fixed shoji 20 is configured by assembling an upper rod 21, a lower rod 22, a left vertical rod 23, and a right vertical rod 24 in a rectangular shape, and mounting a panel (for example, a glass panel) 25 in the compartment. In the present embodiment, as the panel 25, as shown in FIG. 3, a multi-layer glass in which spacers 25c and 25c are sandwiched between two glasses 25a and 25b is illustrated, but a single plate glass may be used. However, from the viewpoint of improving heat insulating properties, double-glazed glass is preferred.

  Further, the fixed shoji 20 is fixed to the upper frame 11 with the upper collar 21, the left frame 13 with the left vertical collar 23, and the right frame 14 with the right vertical collar 24. The position is fixed relative to the frame body 10.

  The movable shoji 30 is configured by assembling an upper rod 31, a lower rod 32, a left vertical rod 33, and a right vertical rod 34 into a square shape, and mounting a panel (for example, a glass panel) 35 in the compartment. In the present embodiment, as the panel 35, as shown in FIG. 3, a multi-layer glass in which spacers 35c and 35c are sandwiched between two glasses 35a and 35b is illustrated, but a single plate glass may be used. However, from the viewpoint of improving heat insulating properties, double-glazed glass is preferred. Moreover, since the raising / lowering window 100 has the effect that the movable shoji 30 can be moved up and down with a small force, when the panel 35 is heavy multilayer glass, there exists a more remarkable effect.

  A handle portion 36 is provided on the indoor side of the upper arm 31 of the movable shoji 30, and the movable shoji 30 can be easily opened and closed by operating the handle portion 36 with a hand. As shown in FIGS. 1 to 3, the upper rod 31 (the pulling portion 36) is configured to cover the lower rod 22 of the fixed shoji 20 when viewed from the indoor side in a closed posture. By setting it as this form, while improving designability, it becomes a structure excellent in watertightness, heat insulation, and crime prevention. That is, by covering the space between the fixed shoddle 20 and the movable shoddle 30 with the upper rod 31 (the handle portion 36) in the closed posture, water and heat can be prevented from entering and leaving to improve water tightness and heat insulation, Security can be improved by making it difficult to insert.

  Further, as shown in FIG. 2, support members 38 and 38 are attached to the lower ends of the left vertical rod 33 and the right vertical rod 34 of the movable shoji 30 so as to protrude outward in the finding direction. The support member 38 has a support portion 38 a that engages with the guide groove 40. The support portion 38a is provided with an annular groove 38b. The annular groove 38b is connected to the balancer 60 provided in each of the upper portions of the vertical frames 13 and 14, and is disposed along the guide groove 40. One end of the wire 61 is locked (see FIGS. 2 and 3). Accordingly, the movable shoji 30 is suspended by the balancers 60 and 60. The balancer 60 is provided with a spiral spring so that the mass of the movable shoji 30 is kept in balance and the movable shoji 30 can be moved up and down with a small force and can be stopped at any height. .

  In the closed posture, the movable shoji 30 is juxtaposed in the same plane as the fixed shoji 20 below the fixed shoji 20 inside the frame 10 as shown in FIG. At this time, the latch 70 (see FIG. 6 (a)) provided on the upper collar 31 so as to protrude outward in the finding direction is a recess (engaged portion) 71 (see FIG. 6) provided on the right vertical frame 14. 6 (a)), and the movable shoji 30 is prevented from rattling. Although FIG. 6 shows only the right vertical frame 14 side, the same applies to the left vertical frame 13 side.

  Moreover, since the movable shoji 30 and the fixed shoji 20 are juxtaposed in the same plane in the closed posture, a member for ensuring airtightness can be provided in the same plane, and the movable shoji and the fixed shoji can be found. The airtightness can be improved compared to the conventional raising and lowering windows that have been shifted in the direction. More specifically, in the raising / lowering window 100, in the closed position, a packing 81 (see FIG. 3) is interposed between the fixed shoji 20 and the upper frame 11, and the packing is disposed between the fixed shoji 20 and the right vertical frame 14. 84 (in FIG. 6, the packing 84 between the movable shoji 30 and the right vertical frame 14 is illustrated, but the packing 84 extends along the right vertical frame 14). Packing (not shown but similar to packing 84) is interposed between the lower vertical frame 13 and the left vertical frame 13, and the packing 82 (see FIG. 3), a packing 83 (see FIG. 3) is interposed between the movable shoji 30 and the lower frame 12, and a packing 84 (see FIG. 6) is interposed between the movable shoji 30 and the right vertical frame 14. Packing between the movable shoji 30 and the left vertical frame 13 (not shown) There is not, but with intervening same.) The packing 84. These packings extend along the upper frame 11, the lower frame 12, the left vertical frame 13 or the right vertical frame 14, and are arranged in substantially the same plane. Therefore, it is easy to ensure airtightness. Moreover, since the movable shoji 30 and the fixed shoji 20 are juxtaposed in the same plane and the packing is disposed in substantially the same plane, the heat insulating property can be improved.

  Furthermore, the movable shoji 30 and the fixed shoji 20 are juxtaposed in the same plane, so that the crime prevention can be improved. In the conventional raising / lowering window, the shovel is pushed up by inserting a bar or the like between the lower arm of the shoji provided at the lower part inside the frame and the lower frame, and the crescent lock attached to the upper part of the shoji is destroyed. There was that. However, in the raising / lowering window 100, the movable shoji 30 and the fixed shoji 20 are juxtaposed in the same plane in a closed posture, so that the bar is inserted between the lower frame 12 and the lower rod 32 to push up the movable shoji 30. Is difficult.

  Next, the opening / closing operation of the guide groove 40 and the movable shoji 30 will be described. As shown in FIG. 3, the guide groove 40 formed in the right vertical frame 14 includes a straight portion 41 and an inclined portion 42. The straight portion 41 extends in the longitudinal direction of the right vertical frame 14 on the inner side in the prospective direction with respect to the fixed shoji 20. The inclined portion 42 communicates with the lower frame 12 side end of the linear portion 41 and extends toward the lower frame 12 side where the fixed shoji 20 is provided.

  The inclination angle θ (see FIG. 3) of the inclined portion 42 with respect to the horizontal plane is not particularly limited, but is preferably in the range of 25 degrees to 45 degrees. When the inclination angle θ is too small, the force required to open the movable shoji 30 increases.

  When opening the movable shoji 30, for example, first, a latch provided on the upper saddle 31 is formed by placing the hand on the pulling portion 36 provided on the indoor side of the upper saddle 31 of the movable shoji 30 and pulling it to the indoor side. 70 is detached from the recess 71 provided in the vertical frames 13 and 14. Then, as shown in FIG. 4, with the support portion 38 a as a fulcrum, the movable shoji 30 is tilted indoors until the latch 70 engages with the guide groove 40. At this time, since the latch 70 and the support portion 38a are engaged with the guide groove 40, the movable shoji 30 is lifted by placing a hand on the handle portion 36 or the handle piece 39 provided on the lower rod 32. As shown in FIG. 5, the movable shoji 30 can be moved upward along the guide groove 40. Further, since the latch 70 is engaged with the guide groove 40, when the movable shoji 30 is moved up and down, rattling of the upper portion of the movable shoji 30 can be prevented.

  When closing the movable shoji 30, first, a hand is placed on the pulling portion 36, the pulling piece 39, etc., and the movable shoji 30 is pulled down until the support portion 38 a reaches the lower end of the guide groove 40. Thereafter, the upper portion of the movable shoji 30 is pushed outward in the prospective direction with the support portion 38a as a fulcrum, so that the latch 70 is detached from the guide groove 40 and the latch 70 is engaged with the recess 71.

  Thus, when raising and lowering the movable shoji 30, the wire 61 rubs at the corner 43 of the communication portion between the straight portion 41 and the inclined portion 42. That is, in the posture in which the movable shoji 30 is closed, as shown in FIG. 3, the wire 61 is in contact with the corner 43 of the communication portion of the straight portion 41 and the inclined portion 42. When 30 is opened and closed, the wire 61 moves and the wire 61 and the corner 43 are rubbed. Therefore, in the raising / lowering window 100, a roller (friction reducing means) 50 having a rotation axis orthogonal to the moving direction of the wire 61 is disposed at the corner 43. The roller 50 is in contact with the wire 61, and when the wire 61 moves, the roller 50 rotates and can be prevented from being worn by rubbing the wire 61 and the corner 43.

  In the present embodiment, the roller 50 is exemplified as the friction reducing unit, but the present invention is not limited to such a form. For example, the corner 43 may be made of a material having excellent wear resistance (such as chromium molybdenum steel), or a solid lubricant may be applied to the corner 43.

  Further, as shown in FIGS. 1 and 6, the raising / lowering window 100 of the present invention is provided with locking devices 37, 37 inside the upper arm 31 of the movable shoji 30. The locking devices 37 and 37 will be described below.

  The locking device 37 includes a handle 37 a provided on the indoor side of the handle portion 36 of the upper collar 31, and an engaging portion 37 b that communicates with the handle 37 a and is provided inside the handle portion 36. In the unlocked posture, the engaging portion 37b is housed inside the handle portion 36 as shown in FIG. When the handle 37a is slid outward in the direction of finding, as shown in FIG. 6B, the engaging portion 37b protrudes outward in the direction of finding and enters the right vertical frame 14 from the hole 72 formed in the right vertical frame 14. While being inserted, it is engaged with the receiving portion (engaged portion) 73 and locked. Further, by sliding the handle 37a from the locking position to the inside in the finding direction, the engaging portion 37b is detached from the hole 72 and unlocked. In FIG. 6, only the right side locking device 37 is illustrated, but the left side locking device 37 is the same.

  The locking devices 37 and 37 do not overlap with the panels 25 and 35 in a front view, and are excellent in design. Moreover, since the locking devices 37 and 37 cannot be seen from the outdoor side, and it is difficult to confirm the position of the key from the outdoor side, it has the effect of being excellent in crime prevention.

  Although the present invention has been described in connection with the most practical and preferred embodiments at the present time, the present invention is not limited to the embodiments disclosed herein, The present invention can be changed as appropriate without departing from the gist or concept of the invention that can be read from the claims and the entire specification, and the raising and lowering windows accompanying such changes should not be understood as being included in the technical scope of the present invention. Don't be.
