Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention shields the solar radiation by raising and lowering the light shielding sheet on the outdoor side of the shoji of the window by a winding / feeding system.ExternalThe present invention relates to a solar radiation shielding device.
[0002]
[Prior art]
As part of measures to promote energy conservation in houses, the standards for the solar radiation acquisition coefficient in the summer have been reviewed, and accordingly, it is strongly desired to improve the solar radiation shielding performance of windows. Since the external solar shading device attached to the outdoor side of the window is excellent in solar shading performance, various types of external solar shading devices have been conventionally used.
The market demand for external solar shading devices is that (a) the entire window can be opened and the entire screen can be shielded against the sun, (b) wind measures are taken, and (c) the mechanism is simple. And (d) simple opening / closing operation.
[0003]
[Problems to be solved by the invention]
  However, conventional external solar shading devices are mainly open / closed type louvers and other large-sized mechanisms, and they have excellent strength, so they have sufficient measures against wind, but the opening / closing mechanism is complicated and opening / closing operations are easy. In addition, the price is also high.
  As a simple type, it has a roll blind body that is mounted along the upper side of the window on the outdoor side, and a guide frame that is mounted along both the left and right sides of the window on the outdoor side. Coupled to the winding shaft urged in the winding direction by the urging means, a bottom bar is coupled to the other end of the light shielding sheet, and the bottom bar is pulled down against the urging force of the urging means along the guide frame So that the shading sheet can be pulled outExternalAlthough the solar radiation shielding device is known, since the stop position of the bottom bar is limited and the conventional product cannot be stopped at an arbitrary position, the shielding area of the window cannot be arbitrarily set. In addition, since the installation position of the roll blind body is above the upper frame of the window frame, the light shielding sheet pulled down to the shielding position is close to the screen door or the shoji of the window, so even when the shaking by the wind is small, The light shielding sheet comes into contact with the screen door or the shoji, causing noise or contamination or damage to the light shielding sheet.
[0004]
  The present invention has been made in view of the above circumstances, and its problem isExternalIn the solar radiation shielding device, an opening / closing operation can be easily performed, and the bottom bar can be stopped at an arbitrary position to arbitrarily set the shielding area of the window.

[Means for Solving the Problems]
  In order to solve the above problems, the present invention provides:(A)A roll blind body that is mounted along the upper side of the window on the outdoor side, and a guide frame that is mounted along the left and right sides of the window on the outdoor side;(B)The roll blind body has one end of a light shielding sheet coupled to a winding shaft urged in a winding direction by an urging means, and a bottom bar coupled to the other end of the light shielding sheet extends along the guide frame. A window configured to be pulled out of the winding shaft by being pulled down against the biasing force of the biasing means;ExternalIn the solar shading device,(C)One end of an arm is coupled to both ends of the bottom bar, and the other end of the arm is connected to the guide frame.Guide grooveCan move up and down freelyTo the guided member fittedFree to rotate around the horizontal axisCombined and beforeStamped handIn stepsMore through the shading sheet and the bottom barThe arm is facing upwardTurned(D) The other end of the arm is moved upward by turning the arm upward.Pressed against the vertical wall of the guide frameStop the rotation of the arm at a certain angle, andOf the armUp and down at the other endThe bottom bar prevents movementAgainst the biasing force of the biasing meansReductionBeingThe armunderTurned toBeforeThe pressure on the vertical wall of the guide frame is released and the armUp and down at the other endAllow movementWith cam surfaceIt is characterized by providing a stopper.
  With the configurations (a) and (b), a winding force is constantly applied to the light shielding sheet from the urging means via the winding shaft. When the pulling force is applied to the bottom bar, the armDownAnd the pressure on the vertical wall of the guide frame on the cam surface of the stopper is released,Both arm and guided memberMove downward along the guide frame. That is, the bottom bar and the arm move together and move downward, and the light shielding sheetWhile maintaining tension by biasing meansShield sunlight from windows. If you release the bottom bar at any position, the force applied by the arm from the light-shielding sheetUpwardRotated to the stopperCam faceHits the vertical wall of the guide frame, preventing further rotation of the arm, and the arm by the frictional force of the stopper against the guide frameAnd guided members andThe bottom bar is prevented from moving upward. Accordingly, the light shielding sheet is stretched so as to shield the window. The light shielding area is determined by the bottom bar stop position.Also, pull down the bottom bar with a small force so that the cam surface of the stopper separates from the vertical wall of the guide frame, move the bottom bar as it is, and then release the hand from the bottom bar, the light shielding area is reduced and fixed, Can be in a state.
[0006]
The arm is preferably inclined so that the bottom bar side is lower than the pivot center of the arm in a state where the arm is prevented from moving upward by the stopper.
In this case, since the arm is easily rotated by the force applied to the bottom bar when the light shielding sheet is shielded or opened, the light shielding sheet can be easily opened and closed.
[0007]
The roll blind body is mounted in a box that extends along the outdoor side of the window and has an opening for feeding out the light shielding sheet on the lower surface, and the box has a coupling edge extending in the indoor side direction from the upper surface wall. It is connected to the upper ends of the left and right guide frames at the connecting edge to form a gate shape, and the guide frame is connected to the outdoor side end of the vertical frame of the window frame or the building outer wall outside the vertical frame of the window frame. It is desirable to have a connecting edge.
With the above configuration, the box and the guide frame are firmly connected in a gate shape, the roll blind main body is stably attached, and the left and right guide frames are connected to the outdoor side end of the vertical frame of the window frame or the vertical length of the window frame. Since it can be connected to the building outer wall outside the frame, the solar shading device can be easily attached to the outside of the existing window frame.
[0008]
It is desirable that both ends of the winding shaft of the roll blind body are rotatably supported by brackets that can be fixed to the box or the hook by screws.
In this case, the roll blind body can be housed and mounted in a box connected to the guide frame, which is separated from the window frame, or can be housed and mounted in a cage attached to the window frame. it can.

It is desirable that a gripping or handling operation portion 16 a protruding downward is attached to an intermediate portion of the bottom bar 16.
The light-shielding sheet 15 may have any name such as blinds, shades, screens, cloths, curtains, etc. as long as it has solar shading performance and weather resistance and can be wound.
[0012]
The structure of the roll blind body 10 that rotatably supports the take-up shaft 13 with respect to the bracket 11 and the structure of the urging means 14 that gives the take-up force to the take-up shaft 13 are merely examples. The invention is not limited to this. The light shielding sheet 15 is always wound around the winding shaft 13 by applying a force in the winding direction. When the bottom bar 16 coupled to the free end of the light shielding sheet is pulled down, the light shielding sheet 15 is taken up by the winding shaft. What is drawn out from 13 is sufficient.
[0013]
In the embodiment illustrated in FIGS. 1 and 2, the roll blind body 10 is mounted in a box 30 that extends along the outdoor side upper side of the window and that has an opening for feeding out the light shielding sheet on the lower surface. The box 30 includes a box body 31 having a U-shaped cross-section that is formed integrally with at least a top wall 31a, a front wall 31b, and a vertical back wall 31c. A substantially rectangular side plate 32 is brought into contact with both ends of the box body 31 in the longitudinal direction, and screws 33 (FIG. 1) are screwed into screw holes 31d formed on the inner surface of the box body 31 from the outside of the side plate. The box body is closed. However, the structure for closing the fore edge of the box body is arbitrary.
The pair of left and right brackets 11 are fixed to the inner surface of the vertical back wall 31c with screws 34, and the roll blind body 10 is housed in the box 30 and protected from wind and snow and atmospheric dust.
[0014]
In a preferred embodiment, a draining wall 31e is integrally extended at the lower end of the front wall 31b of the box 30. A lower plate 31f extending between the lower ends of the left and right side plates 32 is attached to the lower end portion of the vertical rear wall 31c to shield the rear half of the lower surface of the box body, and the lower plate 31f and the front wall 31b. An opening 31g for feeding out the light shielding sheet is formed between the lower end portions of the light shielding sheet.
[0015]
Since the lower plate 31f is detachably attached by the screw 35, the lower plate 31f can be removed and maintenance inspection of the roll blind body 10 can be performed.
[0016]
  In order to provide the box 30 along the upper side of the outdoor side of the window, in the example shown in FIGS.AlsoA connecting edge 31h extending to the object side is integrally formed. Then, the coupling edge 31h is placed on the upper end surfaces of the left and right guide frames 20, 20, which will be described later, and the screw 36 is screwed into the screw hole of the guide frame 20 from the coupling edge 31h, so that the box 30 and the left and right guide frames 20 are Connected to the gate. By connecting to the gate type, the solar shading device can be easily attached to a window frame WF or a building outer wall W described later.
[0017]
As shown in FIG. 3, the guide frame 20 has a guide groove 21 that opens in a direction parallel to the window opening surface, and is provided on one or both of the outdoor side and the indoor side outside the guide groove opening. The vertical wall 22 is integrally formed with a screw hole 23 on the surface opposite to the opening of the guide groove, and a coupling edge 24 is integrally formed on the indoor side end. The coupling edge 24 may be constituted by a single sheet, but in the preferred example shown in the figure, the cross-sectional shape having a fitting groove therein is formed in a square J shape.
In the illustrated example, the left and right guide frames 20, 20 are arranged with the guide grooves 21 opened outward and the screw holes 23 facing each other, and the upper end surfaces of the guide frames are connected to the box body 31. Abutting on the lower surface of the edge 31h, the above-described screw 36 is screwed into the screw hole 23 of the guide frame 20 from the upper side of the connecting edge, thereby being connected to the box 30.
[0018]
One end portions of the left and right arms 40, 40 are coupled to both ends of the bottom bar 16. As shown in the example of the drawing, the screw 44 penetrating the arm is screwed into the screw hole 16b formed inside the bottom bar 16 as in the illustrated example, but it is integrally formed at the end of the arm 40, although not shown. A method of press-fitting the shaft portion into the bottom bar 16 where the screw hole 16b is not formed, or other known connection methods can be used.
The other end of the arm 40 is coupled to a guided member 41 inserted into the guide groove 21 of the guide frame 20 so as to be movable up and down and rotatable. 2 and 3, the guided member 41 is formed by a roller, and a coupling shaft 42 penetrating through the center of the guided member 41 extends outward from the opening of the guide groove 21 and is coupled to the other end of the arm 40. Yes.
[0019]
As shown in FIG. 4A, when the arm 40 is rotated in the direction in which the end on the bottom bar side rises, the other end of the arm 40 abuts against the vertical wall 22 of the guide frame 20. The arm 40 is stopped so as not to rotate any more, and the upward movement of the arm 40 is prevented by the frictional force received from the vertical wall 22, and the arm 40 is moved in the opposite direction as shown in FIG. That is, when the end on the bottom bar side is rotated in the descending direction, a stopper 43 is provided that allows the arm 40 to move downward or upward away from the vertical wall 22 of the guide frame 20. .
[0020]
It is desirable that a sheet-like anti-slip material 25 made of rubber or other material having a high friction coefficient is stuck on the surface of the vertical wall 22 against which the stopper 43 abuts.
[0021]
The stopper 43 illustrated in FIG. 4 is constituted by a cam formed integrally with the other end portion of the arm 40, and the arm is rotated from one end portion and the other end portion of the cam surface that contacts the vertical wall 22 of the guide frame 20. By setting the distances L1 and L2 to the moving center as L1> L2, when the hand is released from the operation portion 16a of the bottom bar 16, the arm 40 by the urging means 14 is rotated clockwise in FIG. The angle at which the arm 40 is stopped is inclined so that the bottom bar side end of the arm 40 is located lower than the arm rotation center. In this way, when the arm stop angle is inclined, as compared with the case where the stop angle is horizontal, the operation of lowering the bottom bar 16 by placing the hand on the operation portion 16a and rotating the arm or lowering the bottom bar to an arbitrary position. The raising work can be easily performed.
[0022]
In the guide groove 21 of the guide frame 20, a stop member 45 (FIG. 1) that hits the guided member 41 and stops it when the light shielding sheet 15 is wound up to the vicinity of its lower end near the upper end. And FIG. 2) are fixed.
[0023]
Although it is necessary to fix the solar radiation shielding device A to a building in a broad sense, either a method of attaching to a window frame or a method of attaching to an outer wall can be adopted as a method of fixing to the building. 1-3 have shown an example in the case of attaching to a window frame. As a method of attaching to the window frame, a method of connecting the guide frame 20 to the vertical frame of the window frame and a method of connecting the box 30 to the upper frame of the window frame are possible.
1-3 show an example in which the guide frame 20 is connected to the vertical frame 50 of the window frame WF. That is, the connection edge 51 formed by bending outward at the outdoor side end of the vertical frame 50 is fitted into the groove of the coupling edge 24 integrally formed at the indoor side end of the guide frame 20. From the outdoor side of the engagement edge 24, the screw 52 is screwed into the connection edge 51 of the vertical frame at a position having an appropriate interval in the vertical direction, thereby being firmly connected.
[0024]
In the case of the illustrated example, the coupling edge 24 and the connection edge 51 are bent in a direction parallel to the opening surface of the window so that the screw 52 can be screwed in from the outdoor side to the indoor direction. However, the screw 52 is screwed in a direction parallel to the opening surface of the window so that the connecting edge 24 and the connecting edge 51 are perpendicular to the opening surface of the window so that the guide frame 20 can be connected to the vertical frame 50 of the window frame. You may form so that it may extend in a direction, ie, an indoor outdoor direction. In this case, the conventional window frame can be used as it is, and the connecting edge of the guide frame can be brought into contact with the inner surface or the outer surface of the outdoor side end portion of the vertical frame, and the screw can be screwed in from the inner side or the outer side of the window frame. .
[0025]
The structure of the window frame WF shown in FIGS. 2 and 3 is merely an example, and the present invention is not limited to this at all. Either an internal sash, a semi-external sash, or an external sash may be used. Moreover, in the same figure, only the shoji 53 and 54 are shown, and the screen door normally installed on the outdoor side is omitted. Furthermore, the shoji screen may be either drawn or drawn.
[0026]
In the case of a semi-external sash or an external sash, the upper end portion of the guide frame 20 is separated from the outer wall W in the outdoor direction as shown in FIG. Accordingly, when the coupling edge 31h of the box body 31 is extended only to the indoor side end of the guide frame 20, a gap is generated between the coupling edge 31h and the outer wall W, and wind, rain, snow, dust, etc. are generated from the gap. May be intruded, which is not preferable. In order to prevent this, it is desirable to extend the connecting edge 31h into an L shape as shown by a chain line in FIG. 2 and to contact the rising portion of the outer wall W with a sealant interposed therebetween.
[0027]
  The operation of the above configuration will be described. When the sun is not shielded, the bottom bar 16 is held at the upper limit position as shown in FIGS. 1 and 2, and at that time, the guided member 41 is stopped by the stop member 45, and the light shielding sheet 15 andBiboThe stopping angle at which the arm 40 is inclined by the stopper 43 abutting against the vertical wall 22 of the guide frame 20 as shown in FIG. 4A due to the pulling force from the urging means 14 applied to the arm 40 via the tom bar 16. Has been stopped at.
  When the bottom bar 16 is pulled down by placing the hand on the operation portion 16a, the arm 40 is rotated counterclockwise as shown in FIG. 4 (b), and the stopper 43 is separated from the vertical wall 22 of the guide frame. Since the downward movement is possible, when the bottom bar 16 is pulled down to an arbitrary position, the light shielding sheet 15 is unwound from the winding shaft 13 to shield the outdoor side surface of the window. When the operation unit 16a is released at a desired position, the arm 40 is rotated clockwise as shown in FIG. 4A by the pulling force applied from the light shielding sheet 15, and returns to the initial stop angle. Again, the arm 40 is pressed against and abutted against the vertical wall 22 of the guide frame to prevent the arm 40 from moving upward, and the bottom bar 16 is held at a position where the arm 40 has returned to the original stop angle. The light shielding sheet 15 is maintained in a tension state by a pulling force applied from the urging means.
  Therefore, the sunlight to the window can be shielded by the light shielding sheet, and the light shielding sheet is not shaken by the wind.
[0028]
The chain line in FIG. 1 shows a state where the bottom bar 16 is pulled down to the lower limit position and the light shielding sheet shields the entire window from light. However, the bottom bar 16 grips the operating portion 16a and pulls it down to an arbitrary position in the middle or pulls it obliquely downward toward the near side while raising it to an arbitrary position by the pulling force of the urging means, and releases the hand from the operating portion 16a. It is possible to stop at that position. Therefore, since the bottom bar stop position can be arbitrarily changed, the amount of light collected, the field of view, and the solar shading can be appropriately adjusted by freely changing the light shielding area according to the height of the sun.
[0029]
5 to 8 show other embodiments of the guided member and the stopper. FIG. 5 is a sectional view showing the shapes of the guide frame and the other end of the arm, FIG. 6 is a side view, and FIG. 5 is a cross-sectional view of another embodiment corresponding to FIG. 5, and FIG. 8 is a cross-sectional view taken along line YY of FIG.
In the embodiment shown in FIGS. 1 to 4, the stopper 43 is constituted by a cam projecting only on the outdoor side. Therefore, the guide frame 20 is provided with the vertical wall 22 on the outdoor side. The vertical walls 22a and 22b are provided on the outdoor side and the indoor side of the opening of the guide groove 21 of the guide frame 20, and the stopper 43 also has two cams 43a and 43b corresponding to the vertical walls. You can also When two cams are provided, the force that the arm 40 receives from the urging means 14 via the light shielding sheet is increased by this principle, and the force applied to the cams is distributed to the vertical walls on both sides of the two cams. There is an advantage that deformation of the cam or the vertical wall is prevented.
Only the vertical wall 22b on the indoor side of the opening of the guide groove 21 of the guide frame may be provided, and the cam may have one cam protruding in the indoor direction.
If the guide frame 20 has a guide groove 21 that guides the guided member 41 so that it can be raised and lowered and a vertical wall 22 that restricts the stopper 43, they are provided either inside or outside the guide frame 20. May be.
[0030]
Furthermore, in the above embodiment, the guided member 41 is constituted by a roller, and the stopper 43 is formed integrally with the other end of the arm 16 to be separated from the guided member 41. However, in FIGS. As illustrated, the guided member 41E is configured by a slider formed in a substantially rectangular shape, and the guided member is obliquely fixed to the arm 16 by the coupling shaft 42, and the arm of the diagonals of the guided member It is also possible to provide a cam surface 43E at one or both corners existing on a parallel diagonal line, and to integrally form a stopper on the guided member 41E. In this case, the inner surface 22E on the outdoor side or indoor side of the guide groove 21 also serves as the vertical walls 22a and 22b. Further, if the guided member and the stopper are formed integrally with the arm 16, it can be simplified as a single part.
Only the guided member 41 in FIGS. 2 to 6 may be a rectangular slider, and the stopper 43 may be as shown in FIGS.
[0031]
The example of FIGS. 1 to 3 is a case where the left and right guide frames 20, 20 are connected to the left and right vertical frames 50, 50 of the window frame. If a bent attachment edge is provided, the attachment edge can be fixed to the outer wall of the building with screws or the like outside the vertical frame of the window frame. Further, the connecting edge 31h of the box body 31 is further extended in an L shape in the indoor direction as described above, and the mounting edge constituted by the rising portion is formed on the outer wall W of the building above the upper frame 55 of the window frame. It can be fixed with screws or the like. With such a mounting structure, the mounting strength of the solar shading device A can be remarkably increased. By providing such a mounting edge on the guide frame and / or the box body, the solar shading device can be easily mounted on a window to which the window frame has already been mounted without any additional work on the window frame. The solar radiation acquisition coefficient of the window can be reduced.
[0032]
As another embodiment of the present invention, the roll blind main body 10 is not housed in a box, and is opened downward in a normal fence 60 provided along the upper side of the window frame on the outdoor side, as shown in FIG. Forming the receiving recess, storing the roll blind body 10 in the receiving recess, attaching the bracket 11 to the flange 60 with a screw or the like, and fixing the guide frame 20 to the vertical frame 50 of the window frame WF with screws 56, Even without specially complicated processing, the solar radiation shielding function can be easily provided.
[0033]
Furthermore, in the solar shading device according to the previous embodiment, the roll blind main body 10 is housed in the box 30 and protected from wind and snow etc., so that the box 30 is attached to the box main body 31 as illustrated in FIG. In the vertical back wall 31c, it can be easily coupled to the outdoor side of the shutter box 70 provided on the upper side of the outdoor side of the window. By using the guide groove 71a for guiding the shutter slats on the inner surface and the shutter guide frame 71 integrally formed with the guide grooves 21 and the vertical walls 22E of FIG. A solar shading device can be attached to the outdoor side of a window equipped with a roll-up shutter.
The shutter guide frame 71 may be a dedicated one for a conventional roll-up type shutter, and the guide frame 20 dedicated for the roll blind may be connected to the outdoor side of the shutter guide frame. In the case of the latter mounting structure, the number of components increases, and the expected width from the building outer wall to the roll blind guide frame increases, whereas the example illustrated in FIG. 10 has a small number of components. There is an advantage that the expected range is shortened.
