Description

  The present invention, when a screen for securing insect protection and ventilation in a building opening is not necessarily required to be stored when not in use, and is fixedly installed, shading on the building opening, sunshade, The present invention relates to a screen device with a blind function suitable for performing blindfolding.

  In order to ensure the insect prevention and ventilation in the opening of the building, it is very common to install a net-like screen to ensure the insect prevention and ventilation. In that case, if there is almost no entry or exit of people or objects through the building opening, the screen is fixed within a range that does not hinder the opening and closing of the door that opens and closes the building opening. There is no problem.

  By the way, in such building openings, when shading, awning, blindfolding, etc. are required, it is possible to adjust the inclination angle of the slats by holding a large number of slats up and down at regular intervals. The known blind device may be installed along the screen. However, when the slat is a hard material such as an aluminum material, it is usually provided on the indoor side, so that it is in contact with the occupants in the room. The slats that tilt can not only make contact with the screen and make a contact sound, but also wear the screen. That said, it is not only difficult to install the blind device outside the screen, but also difficult to tilt the slats. That.

  On the other hand, a screen door with a blind function in which a screen door installed at an opening of a building and a blind function are provided together has already been disclosed in Patent Document 1 and the like. However, in the thing disclosed in the patent document, it is possible to open and close the slat by operating the opening and closing operation tool of the screen on the premise that the entire screen can be taken up by the take-up shaft together with the slat. . For this reason, the slat is also opened and closed while maintaining the insect-proof function by the opening and closing operation tool of the screen, and the mechanism of the opening and closing operation must be relatively complicated, and the mechanism is essentially unnecessary. Since the slats are opened by further operation of the opening / closing operation tool after the screen is stretched, the blind opening / closing operation is not simple and light.

  1 to 7 show a first embodiment of a screen device with a blind function according to the present invention. This screen device with a blind function tries to be installed almost fixedly on the assumption that the screen for securing insects and ventilation at the opening of the building does not necessarily have to be wound up or stored horizontally. It is suitable for cases where it is intended to have a blind structure having functions such as shading, awning, blindfolding, etc. for the opening of the building. Therefore, the mechanism for tilting the slats constituting the blind is very simple and can be opened and closed by a simple and light operation.

First, referring to FIG. 1 to FIG. 5, a net-like first screen 11 for securing insect protection and ventilation, a second screen 12 and a plurality of slats 13 which are integrated with the first screen 11 and constitute a blind mechanism. The configuration of the screen unit 10 made up of will be described.
The screen unit 10 has a net-like light-transmitting first screen 11, has air permeability and light-transmitting properties, and is arranged so as to face the first screen 11. The second screen 12 used for the tilting operation of the slat 13 and the first screen 11 and the second screen 12 are connected to each other at an interval in the vertical direction. 12 is configured by a large number of the slats 13 whose ends are connected to each other so that the first screen 11 can be tilted up and down, and the first screen 11 is arranged on the outdoor side, and the second screen 12 is on the indoor side. It is installed in the building opening.

  The configuration of the screen unit 10 will be described in more detail. The slat 13 is made of a flexible sheet-like member that limits the amount of transmitted light for light control or light shielding. The first screen 11 and the second screen 12 are spaced apart from each other and fixed to each other by bonding, welding, sewing or knitting.

  Further, in the screen unit 10, in principle, the first screen 11 and the second screen 12 are expanded and overlapped with each slat 13 having both ends connected between them to form a plane. Then, adjacent portions of the slats 13 connected between the screens 11 and 12 are overlapped with each other, and at least a large number of slats 13 are disposed so as to cover the first screen 11 as a whole. Thus, the slats 13 shield the building openings, but the overlapping length of the adjacent portions of the slats 13 is when the slats 13 are opened by the tilting of the slats 13. Depending on the desired amount of light collected, it can be selected as appropriate.

  As shown in FIGS. 4 to 7, the first screen 11 for securing insect protection and ventilation in the screen unit 10 is held by the screen frame 15 on each side of the left and right and upper and lower ends. A large number of engagement elements 11a are attached. As shown in FIG. 6, the engaging elements 11 a provided on the left and right sides of the first screen 11 are engaged with the slits of the rail 16 provided on the inner side of the side frame 15 a of the screen frame 15 to hold the screen 11. The engaging elements 11a provided on the upper and lower sides of the first screen 11 are provided inside the upper and lower horizontal frames 15b and 15c of the screen frame 15, as shown in FIGS. The first screen 11 is stretched on the screen frame 15 fixedly attached to the building opening frame by holding the screen 11 in the mounting groove via the mounting member 17.

  As shown clearly in FIG. 7, the mounting member 17 is formed as a member having a substantially U-shaped cross section having a tendency to open elastically with a synthetic resin, and an engagement element 11a of the screen 11 is formed therein. Is provided, and an outwardly engaging engagement bar 17b that is engaged with the recess in the mounting groove is detachably provided on one of the edges of the slit 17a. Moreover, as many engaging elements 11a attached to the circumference | surroundings of the said 1st screen 11, the half body joined mutually, for example, or the member equivalent to it is used frequently in clothes. be able to.

  On the other hand, the second screen 12 in the screen unit 10 needs to be lifted and lowered in a stretched state for tilting the slat 13, so that the second screen 12 faces the screen frame 15. The lower operation frame 19 that is manually moved up and down and the upper frame 20 that is guided or held on the upper part of the screen frame 15 and moves up and down in conjunction with the lifting operation of the operation frame 19. And connecting the operation frame 19 and the upper frame 20 with an interlocking member 21 as will be described in detail below, thereby forming an interlocking frame 18 as illustrated in FIG. ing. The lower end of the second screen 12 is attached to the operation frame 19 and the upper end of the screen 12 is attached to the upper frame 20 that moves up and down in conjunction with the operation frame 19 so that they can be moved up and down manually. doing.

  The configuration of the interlocking frame 18 of the first embodiment shown in FIG. 3 will be described more specifically. In the first embodiment, the above-mentioned interlocking member 21 in the interlocking frame 18 is the lower operation frame 19 and the upper operation frame 19. The connecting frame member 21a that mechanically connects both ends of the upper frame 20 is used to link the operation frame 19 and the upper frame 20, but the operation frame 19 and the upper frame 20 are connected to each other. As in the second embodiment, which will be described later, the mechanical connection is not necessarily required. Therefore, the description of the present invention includes the case where the mechanical connection such as the connection frame member 21a is not performed. The members that are connected so as to be interlocked while holding the operation frame 19 and the upper frame 20 up and down at regular intervals are collectively referred to as an interlocking member 21, and the operation frame 19 and the upper frame 20 are connected by the interlocking member 21. The thing that was moved up and down in conjunction with It is called Dowaku 18.

  The upper and lower ends of the second screen 12 to the interlocking frame 18 are attached to the upper frame 20 of the interlocking frame 18 with the upper end of the second screen 12 as shown in FIGS. The lower end of the screen 12 is attached to the operation frame 19 at the lower part of the interlocking frame 18. The mounting structure for the interlocking frame 18 shown in the figure is the screen frame 15 at the upper and lower ends of the first screen 11. Since there is no place different from the mounting structure, the description is omitted here with the aid of those descriptions. The interlocking frame 18 that supports the second screen 12 has both the left and right ends of the lower operation frame 19 and the upper frame 20 connected to each other by a connecting frame member 21a. Since the side edges of the screen 12 do not need to be connected to the connecting frame member 21a, both side edges of the second screen 12 are in a free state. The connecting frame member 21a can be held by the same mounting structure as that of the screen 11.

  The operation frame 19 provided at the lower part of the interlocking frame 18 that supports the second screen 12 includes an operation element 19a for manually raising and lowering the interlocking frame 18 on the front surface, and the operation element 19a is stable. In order to tilt the slat 13 by a simple operation, guide portions 24a and 24b for guiding the operation frame 19 and the upper frame 20 of the interlocking frame 18 are provided on the upper, lower, left and right sides of the screen frame 15, These guide the elevation of the convex pieces 25a, 26a (see FIGS. 1 and 6) of the end caps 25, 26 provided at both ends of the upper frame 20 and the operation frame 19. Since the ascending / descending range of the interlocking frame 18 on which the second screen 12 is stretched is within the range of opening and closing due to the tilt of the slat 13 by the second screen 12, the guide portions 24a and 24b are installed only within the range. do it.

  Further, in order to make it possible to hold the slat 13 at a desired opening / closing position by raising and lowering the second screen 12 by the operation frame 19, as shown in FIG. An engagement / disengagement member 28 is provided that adjusts the raising / lowering position of the operation frame 19 and supports the operation frame 19 in a fixable manner. The engagement / disengagement member 28 is provided with a plurality of locking protrusions 28a arranged in the vertical direction on the operation frame 19 which is one of the proximity surfaces between the screen frame 15 and the operation frame 19, and the screen frame. 15, the lower horizontal frame 15 c is formed by providing a locking protrusion 28 b that is locked to one of the locking protrusions 28 a and prevents the operation frame 19 from descending.

  In the configuration example of the engagement / disengagement member 28 shown in FIG. 7, a large number of locking protrusions 28a provided on the end cap 25 of the operation frame 19 of the engagement / disengagement member 28 are arranged on the lower surface side of the triangular protrusion 28a. It is assumed that the upper surface side is arranged in a vertical direction with the horizontal surface and the upper surface side facing downward, and the locking protrusion 28b provided on the end cap 26 of the lower horizontal frame 15c of the screen frame 15 Although it is made into the horizontal surface shape latched to either of the protrusions 28a, one of the engagement protrusions 28a is engaged with the engagement protrusion 28b on the lower horizontal frame 15c side, and the operation frame is placed at that position. If it can hold, it may be different from the example shown in the figure.

  The operation of the engagement / disengagement member 28 having the above-described configuration is performed by pulling the operation element 19a of the operation frame 19 in the interlocking frame 18 in the direction indicated by the arrow A in FIG. 7 and engaging the engagement protrusion 28a and the engagement protrusion 28b. In a state where the lock is released, the operation frame 19 is moved up and down to a desired position by the movement of the operation element 19a in the direction of arrow B, and the operation frame 19 is pressed toward the screen frame 15 at that position. What is necessary is just to latch 28b to the latching protrusion 28a of desired height, and, thereby, the slat 13 can be hold | maintained in a desired adjustment position. When locking between the locking protrusion 28a and the locking protrusion 28b is unstable, raising and lowering of the protruding pieces 25a, 26a of the end caps 25, 26 provided at both ends of the operation frame 19 and the lower horizontal frame 15c. In the guide portions 24a and 24b for guiding the protrusions 25a and 24b, an elastic member for pressing both or one of the convex pieces 25a and 26a in the direction in which the locking protrusion 28a and the locking protrusion 28b are joined is provided. What is necessary is to consider means.

  In addition, as described above, the screen device has functions such as shading, sunshade, blindfolding, etc. when the first screen stretched in the opening of the building is fixedly installed as it is not necessarily stored. The first screen 11 as shown in FIGS. 6 and 7 is suitable for the case where it is necessary to open the building opening. The attachment members 17 holding the engagement elements 11 a attached to the upper and lower ends of the first screen 11 are removed from the upper and lower horizontal frames 15 b and 15 c, and the engagement elements 11 a attached to the left and right ends of the first screen 11 are moved along the rails 16. The first screen 11 can be removed from the screen frame 15 together with the second screen 12 by being extracted in the vertical direction. Also, by making such removal possible, it becomes easy to clean and replace the first screen 11 and the second screen 12.

Next, a second embodiment of the screen device with a blind function according to the present invention will be described with reference to FIGS.
The configuration of the second embodiment can use the same screen unit 10 as that of the first embodiment. Similarly to the first embodiment, the slats are moved up and down by moving the interlocking frame 18 holding the second screen 12. 13 is basically the same as the first embodiment in that it tilts, and in particular, it is necessary to wind up a screen for securing insect protection and ventilation at the opening of the building or to store it by horizontal pulling. This is suitable for providing a blind structure having functions such as shading, awning, blindfolding, etc. for the building opening when it is intended to be installed almost fixedly.

  The greatest feature of the second embodiment that differs from the first embodiment is that the interlocking frame 18 that holds the upper and lower ends of the second screen 12, particularly the structure of the upper frame 20 itself, The structure of the interlocking member 21 for interlocking the frame 20 and the operation frame 19 will be described below. The structure and operation of the upper frame 20 and the interlocking member 21 in the second embodiment will be described in detail below. For parts other than the related configuration that are common to the first embodiment, the same reference numerals as those in the first embodiment are assigned to the corresponding parts in the drawings in order to avoid duplication, and description thereof is omitted.

  As clearly shown in FIGS. 8 to 11, in the screen device with a blind function of the second embodiment, first, the upper frame 20 of the first embodiment to which the upper end of the second screen 12 in the screen unit 10 is attached. The corresponding member is constituted by a rotating frame 22 having one end supported on the upper portion of the screen frame 15 and having the second screen 12 attached to the tip, and the rotating frame 22 moves up the second screen 12 at the tip. The interlocking frame 18 connects the rotating frame 22 and the operation frame 19 with the second screen 12 itself as the interlocking member 21 so as to rotate in the direction of rotation. It is comprised by.

  On the other hand, at the lower end portion of the interlocking frame 18 to which the operation frame 19 of the second screen 12 is attached, as in the first embodiment, end caps provided at both ends of the operation frame 19 provided with the operation element 19a. The up and down of the 26 convex pieces 26 a are guided by guide portions 24 b provided on the lower left and right of the screen frame 15. On the other hand, since the upper end of the second screen 12 is attached to the tip of the rotating frame 22 and is moved up and down by the rotation of the rotating frame 22, the second screen 12 in the first embodiment is used. Thus, there is no need to guide, and for this reason, a mechanism for guiding the movement of the upper end of the second screen 12 is not separately provided.

  Also, in the screen device of the second embodiment in which the interlocking frame 18 has the above-described configuration, the ascending / descending position of the interlocking frame 18 by the operation frame 19 is provided between the screen frame 15 as in the first embodiment. In addition, it is necessary to adjust and fix by the engaging / disengaging member 29 (see FIG. 12). However, in the first embodiment, since the force acting on the interlocking frame 18 is only gravity, the engagement / disengagement member 28 raises the operation frame 19 against the gravity so that the operation frame 19 is In the second embodiment, the second screen 12 is attached to the tip of the rotary frame 22 corresponding to the upper frame 20 and the coil is used to move the screen 12 upward. Since the biasing force of the spring 22a is applied, it is necessary to provide the engaging / disengaging member 29 for holding the operation frame 19 so that the second screen 12 does not move up more than necessary due to the force.

  Although the specific configuration of the engaging / disengaging member 29 in the second embodiment is not shown, it is preferably located at the same position as in the first embodiment, preferably from the end cap 26 of the operation frame 19 in FIG. A plurality of locking protrusions 28a in FIG. 7 of the first embodiment, and locking protrusions 28b for locking to either of them, provided between the protruding piece 26a protruding into 24b and the inner wall of the guide portion 24b. May be held upside down, that is, so as not to move up from the position where the operation frame 19 is held by the engaging / disengaging member.

  In the screen device of the second embodiment having the above-described configuration, the operation frame 19 is unlocked by the engagement / disengagement member 29 while the second screen 12 is lowered and the slat 13 is in the shielding position, and the operation is performed. When the upward movement of the frame 19 is allowed, the operation frame 19 is moved upward via the second screen 12 by the urging force of the spring 22a acting on the rotary frame 22, and as a result, the second screen 12 is moved upward. As a result, the slat 13 is opened. At this time, when the rotary frame 22 is rotated to the upper limit shown in FIG. 8, the slat 13 is released to the fully open position, and the upward movement of the operation frame 19 is stopped at the desired position. If the operation frame 19 is fixed to the screen frame 15 by the removing member 29, the slat 13 is held in the open state at that position.

  In the screen device of the second embodiment having such a configuration, as apparent from the above description, when the operation frame 19 is unlocked by the engagement / disengagement member 29 and the operation frame 19 is moved up, the screen device rotates. The frame 22 is rotated by the urging force of the spring 22a. With the rotation, the tip of the rotary frame 22 to which the upper end of the second screen 12 is attached protrudes indoors as shown in FIGS. However, since the lower end of the second screen 12 simply moves up along the screen frame 15, the upper portion of the second screen 12 protrudes into the room and is inclined.

  However, in FIG. 8 and FIG. 10, since the vertical length of the screen unit 10 is shortened and schematically drawn from the relationship of the size of the illustrated paper surface, a realistic product with a longer vertical length is drawn. In FIG. 10, the inclination is extremely slight. In particular, when the rotary frame 22 is at the rotational position of FIG. 10, the operation frame 19 is moved upward so that the tensile force of the spring 22a does not act on the second screen 12. If the second screen 12 is in a state where the second screen 12 relaxes and hangs down, or if the second screen 12 hangs down directly by auxiliary means, the second screen 12 and the first screen 11 The second screen 12 is generally kept in a substantially parallel state, and the entire slat 13 can be fully opened. Therefore, when the slat 13 is fully opened in the screen device of the second embodiment, the second screen 12 is not necessarily in the state shown in FIGS.

  However, taking advantage of the fact that the upper portion of the second screen 12 protrudes indoors by the rotating frame 22 and the second screen 12 is inclined, the rotating frame 22 rotates as shown in FIG. In the upper part of the screen device, the upper part of the second screen 12 is separated from the first screen 11, so that the slat 13 is in the fully open position and good ventilation and lighting are obtained. In the lower part of the screen device, the slat 13 can be hung down and a blinded state can be obtained.

  In the second embodiment, the upper end of the second screen 12 protrudes indoors by the rotation of the spring 22a of the rotating frame 22, and the lower end of the second screen 12 simply moves upward. Although the second screen 12 is configured to be in an inclined state, the second screen 12 is inclined because the operation frame 19 as shown in FIGS. 8 and 9 is guided up and down. This is because the guide portion 24b is formed so as to guide the convex piece 26a of the end cap 26 of the operation frame 19 up and down along the screen frame 15, and the guide portion 24b is configured to project the convex portion of the end cap 26. If the piece 26a is formed so as to be guided obliquely upward to the indoor side from the position along the screen frame 15 to the protruding position of the tip of the rotary frame 22, the second screen 12 The upper and lower portions when the temperature is moved together in a direction away from the first screen 11, so that both screens are kept parallel.

  Also in the first embodiment, it is desirable to move the second screen 12 to the indoor side when the slat 13 is opened. In this case, the upper frame 20 and the operation frame 19 provided on the upper and lower portions of the interlocking frame 18. As in the case of the second embodiment, the guide portions 24a and 24b provided on the upper and lower left and right sides of the screen frame 15 are connected to the upper frame 20 and the operation frame 19, respectively. The convex pieces 25a, 26a of the end caps 25, 26 may be formed so as to be guided obliquely upward to the indoor side from a position along the screen frame 15 to a position necessary for the extension of the slats 13.

  Further, in the first embodiment, as the interlocking member 21 in the interlocking frame 18, a connecting frame member 21a that mechanically connects the lower operation frame 19 and the upper upper frame 20 is used. In the second embodiment, the second screen 12 itself is used as the interlocking member 21, thereby connecting the operation frame 19 and the rotating frame 22 to constitute the interlocking frame 18. However, the interlocking member 21 that connects the operation frame 19 and the upper frame 20 so as to be interlocked while being held at regular intervals should not be limited to the above-described embodiment. The upper frame 20 and the operation frame 19 are connected directly or indirectly to a flexible wire such as a string that is wound around a pulley between the upper and lower sides of the frame 15 and moves up and down. It is also possible to adopt a structure that is connected so as to move up and down.
