Description

The present invention relates to a raised shade with improved shielding properties.

As a kind of cover for windows and openings, a tucked-up shade that opens and closes by moving the suspended fabric up and down is well known. The raised shade can be installed inside the window frame or in front of the window frame, but when installed in front of the window frame, there is no gap between the shade and the window frame in order to block the outside air and direct sunlight. It is preferable to do so.

As a roll screen having no gap between the shade and the window frame, for example, Patent Document 1 discloses a roll screen provided with guide rails on the left and right sides of the roll screen, and the left and right edges of the screen are held by the guide rails. .. While the holding structure of the roll screen of Patent Document 1 is extremely excellent in shielding property, the structure is complicated such that the guide rail and the base of the guide rail must be installed on the inner side surface of the window frame, and the appearance is also Roman. It was incompatible with the lightness of the shade.

Patent Document 2 discloses an invention in which a Roman shade completely covers a window frame with a shade to provide a shade elevating device that looks good even when viewed from a room. In Patent Document 2, a design member attached to the window frame and slightly wider than the window frame, an elevating mechanism attached to the upper surface inside the window frame, and an elevating mechanism arranged on the indoor side of the elevating mechanism, the upper part of which is the window frame. A Roman shade is disclosed that includes a shielding member (shade) that is covered with a design member attached to the. The lower end of the elevating cord of the elevating mechanism is attached to the lower part of the shade. According to the invention of Patent Document 2, the shade suspended from the window frame surface is pulled in the direction of the window frame by a lifting string hanging from the elevating mechanism arranged in the window frame, so that the shade is brought into close contact with the window frame. Intended to let you.

Further, as a Roman shade in which the shade and the window frame are close to each other, Patent Document 3 describes a shielding material (shade), an elevating cord having a lower end attached to the lower part of the shielding material, and an operating cord for operating the elevating cord. In a Roman shade provided with an elevating mechanism, the elevating mechanism is provided in front of the shade and outside the width of the shade, and the operating string is arranged in front of the shade. Further, Patent Document 3 discloses that the operation string is arranged in front of the shade, while the elevating string is arranged on the outdoor side of the shade. According to this configuration, an outdoor force is applied to the elevating string. There is a description that the shade can be brought into close contact with the window frame.

In each of the Roman shades of Patent Documents 2 and 3, the elevating cord attached to the shade is arranged on the window side of the shade, and the shade is pulled toward the window side by the elevating cord to bring the shade into close contact with the window frame. However, since the shade is pulled by the elevating cord, the load applied to the elevating cord is large, and there is a possibility that the elevating cord may be damaged. In addition, this structure is not effective when the lifting string is not tensioned, but in the Roman shade of the automatic descent mechanism, which has been increasing in recent years, tension is not applied to the lifting string when the shade is lowered. A sufficient effect cannot be obtained depending on the structure.

FIG. 1 is a schematic view showing a side structure of a raised shade according to an embodiment of the present invention, and shows only a main configuration. The lift-up shade generally includes an elevating device 1, a shade 2, an elevating cord 5, and a support member 8. The elevating device 1 has a known structure, has substantially the same width as the width (inner dimension) of the window frame 10, and the front surface of the elevating device 1 is substantially flush with the front surface of the window frame 10 on the upper surface inside the window frame. It is installed so that it becomes. The elevating device 1 may be attached to the upper surface inside the window frame via a bracket, if necessary. When using a bracket, a part of the bracket may project forward and / or rearward of the shade. The elevating device 1 has a head rail which is an outer frame of the elevating device, and the head rail incorporates a take-up drum 4 and a pulley, and an operation unit, a clutch, and other known members on which an operation cord is suspended. Built-in.

The upper end of the shade 2 is fixed to the front surface of the head rail of the elevating device 1 by a hook-and-loop fastener, and the shade 2 is suspended from the elevating device 1. That is, in the example of FIG. 1, the head rail of the elevating device 1 is a hanging portion, and the shade 2 is suspended along the front surface of the window frame. The width of the shade 2 is made wider by about 10 to 120 mm than the width of the elevating device 1, and the shade 2 covers the left and right frames of the window frame. The lower end of the shade 2 is formed in a tubular shape, and a weight bar 3 having a width substantially the same as that of the shade 2 is inserted. In the illustrated example, the upper end of the shade 2 is fixed to the front surface of the head rail of the elevating device 1 and suspended, but the arrangement of the elevating device and the hanging mode of the shade are not limited to this, and the shade is hung. The hanging portion for hanging and the lifting device may be separated from each other. For example, the hanging portion may be arranged on the upper portion outside the window frame or the upper surface of the window frame, and the shade may be suspended from the hanging portion. The means for locking the shade to the hanging portion is not particularly limited, and a hook-and-loop fastener, a fastener, a hook, or the like can be used.

A plurality of elevating cord guide rings 6 provided at predetermined intervals in the vertical direction are attached to the back surface of the shade 2, and the elevating cords 5 are inserted through the guide rings 6. The elevating cord guide ring 6 is attached at intervals of about 100 to 300 mm in the vertical direction. The specific shape of the elevating cord guide ring 6 is not particularly limited, and a guide ring having an annular shape, a D-shaped ring shape, an e-shaped shape, a θ-shaped shape, or any other known shape can be selected and used. .. In particular, when one end of the support member 8 is locked to the elevating cord guide ring 6, it is preferable to use a guide ring having a plurality of annular portions so that the elevating cord and the support member do not interfere with each other. A reinforcing tape may be attached to the back surface of the shade 2 along a plurality of guide rings 6 provided in the vertical direction, and it is also preferable that a ring tape provided with the guide rings 6 is attached in advance.

The elevating cord 5 is a cord having a thickness of about 2 mm, and it is preferable that a plurality of elevating cords are provided at predetermined intervals in the width direction of the shade 2. The elevating cord 5 is provided, for example, near the left and right ends and at intervals of about 200 to 400 mm. The vicinity of the left and right ends means a region inside about 5 to 100 mm from the left and right ends of the shade fabric. The lower end of the elevating cord 5 is wound or tied to the cord ring 7 and locked to the shade 2.

The upper end of the support member 8 is engaged with the rear end portion of the elevating device 1, and the lower end of the support member 8 is engaged with the uppermost guide ring 6. That is, the shade 2 is in a state of being pulled backward and upward by the support member 8. When the support member 8 is not present (see FIG. 9) as in the conventional case, the shade 2 hangs vertically downward due to its own weight and the load of the weight bar, or is pulled slightly backward by the elevating cord 5. However, in the present invention, the support member 8 is newly provided, and the shade 2 is pulled backward to ensure that the shade 2 is in contact with the window frame.

The specific configuration of the support member 8 is not particularly limited as long as the effects of the present invention can be obtained, but may be, for example, a string-shaped body or a rod-shaped body. In the case of a string-shaped body, both ends of one string may be engaged with the elevating device and the shade, respectively, or may be ring-shaped. In the case of a rod-shaped body, it is preferable that it has a screw type turnbuckle mechanism, a tubular slide structure, or the like, and its length is variable from the viewpoint of adjusting the adhesion between the shade and the window frame. Even if it is string-shaped, it is preferable that it has a cord stopper and a knot and the length can be adjusted. The length of the support member 8 of the present invention does not need to be adjusted in normal use, but the shade may expand or contract due to washing or other factors. In such a case, when the shade is lowered, the shade may expand or contract. It is preferable to adjust the length so that wrinkles and bias do not occur. Further, the support member 8 may be made of a non-stretchable material, but it is also preferable that the support member 8 is made of a stretchable material such as rubber or elastomer fiber. When the shade 2 is pulled up to the uppermost part, the guide ring 6 is pulled up to just below the elevating device 1, so that the support member 8 is in a slackened state. However, when the support member 8 has elasticity, the shade reaches the uppermost part. The support member 8 does not hang down even in the tucked up state, and does not spoil the aesthetic appearance. It is also preferable that the end of the support member 8 is formed in a hook shape, a clip shape, or the like, and is detachably attached to the guide ring 6 or the elevating device 1.

In the example of FIG. 1, the lower end of the support member 8 is locked to the shade 2 via the guide ring 6 which is a locking member, but the mounting structure is not particularly limited. For example, the support member 8 may be directly attached to the back surface of the shade 2 without using the locking member. Adhesion, sewing, suturing, hook-and-loop fastener, etc. can be used for attachment. It is also possible to provide a floating structure on the fabric of the shade 2 and attach a support member to the structure. When the support member 8 is locked to the shade 2 via the locking member, the guide ring 6 may be used, or the support member 8 may be locked via the loop of the ring tape attached to the shade 2. It can also be locked via a locking member (clip, ring, etc.) attached to the loop. By using a locking member having two annular portions as in the guide ring 6 shown in FIG. 1, interference between the elevating cord and the support member is prevented, which is smoother and less likely to be damaged. There are advantages. The method of attaching the locking member to the shade 2 is not particularly limited, and any known method such as adhesion, sewing, clipping, welding, etc. can be used.

In the example of FIG. 1, the upper end of the support member 8 is locked to the rear end of the lifting device, but the mounting location of the upper end of the support member 8 is raised and lowered in order to generate a force for pulling the shade 2 backward. It is not limited as long as it is behind the winding drum 4 of the cord. However, it is preferable that the support member is rearward and above the mounting position of the lower end. For example, when the elevating device 1 is attached to the window frame via the bracket, it is also preferable to lock the upper end of the support member to the bracket. Further, the support member may be locked on the upper surface of the window frame. The method of locking is not particularly limited, and each of the above-mentioned methods may be used, or the devices may be connected by using an elevating device, a screw hole of a bracket, or the like. Further, it may be further attached between the elevating device 1 or its bracket and the support member 8 via a locking member.

FIG. 2 is a schematic view showing the back surface of the raised shade of FIG. The width of the elevating device 1 is substantially the same as the inner dimension of the window frame (not shown), and the width of the shade 2 is wider than the width of the elevating device 1 so as to cover the left and right sides of the window frame. That is, the left and right protruding portions of the shade 2 come into contact with the left and right window frames. In FIG. 2, three elevating cords 5 are arranged at equal intervals, and among the elevating cords 5, those located near the left and right ends are arranged at positions of about 5 to 80 mm from the left end and the right end of the shade, respectively. .. The support members 8 are provided in the vicinity of the left and right ends, respectively. The number of the support members 8 may be only one, but from the viewpoint of bringing the shade into contact with the left and right sides of the window frame, the support members 8 may be provided near the left and right ends of the shade (positions 30 to 100 mm inside from the end of the shade). preferable.

FIG. 3 shows an embodiment in which the positions of the support members and the locking structure are different. In the example of FIG. 3, the upper end of the support member 18 is locked to the elevating device 1, and the lower end thereof is directly locked to the shade 2.

FIG. 4 shows an embodiment in which the positions of the support members and the locking structure are different. In the example of FIG. 4, an elongated rod-shaped locking member 29 is horizontally attached to the back surface of the shade 2, and the support member 28 is locked to the shade 2 via the locking member 29. When the support member is locked to the shade, the force for pulling the shade backward can be dispersed by the locking member being in contact with the shade in a linear or planar shape through the locking member. It is preferable because it suppresses wrinkles and twitching on the surface of the shade. The material of the locking member 29 is not particularly limited as long as the effect of the present invention is obtained, but may be, for example, a thin resin rod or a thin hard resin sheet, or may be a fiber or resin tape or the like. Good.

FIG. 5 shows an embodiment in which the positions of the support members and the locking structure are different. In the example of FIG. 5, a support member guide ring 9 is provided on the back surface of the shade 2. A plurality of support member guide rings 9 are provided on the left and right sides of the shade 2 in the vertical direction, and a string-shaped support member 38 is inserted through the support member guide ring 9. The support member 38 is locked to the shade 2 at the lower part of the shade 2 via a plurality of guide rings 9. As the support member guide ring 9, the same type as the elevating cord guide ring 6 may be used, or a guide ring having one or more annular portions may be used.

FIG. 6 is a schematic view showing the side structure of the embodiment of FIG. 5, omitting the elevating cord and showing only the shade, the support member, and the mounting structure thereof. A support member guide ring 9 is attached to the shade 2 via an attachment member, and a string-shaped support member 38 is inserted through the support member guide ring 9. The upper end of the support member is fixed to the rear end of the elevating device 1. According to the embodiment of the embodiment shown in FIGS. 5 and 6, tension is not applied to the support member while the shade is being raised and lowered, so that a force for pulling the shade backward does not work and the shade and the window frame rub against each other. Is prevented. On the other hand, when the shade is lowered to the lowermost position, tension is applied to the support member as shown in FIG. 6, and the shade can be pulled rearward to come into contact with the window frame.

FIG. 7 is a schematic view showing the side structure of the raised shade according to a further embodiment of the present invention, and shows only the main configuration. The attachment to the elevating device 1, the shade 2, and the window frame 10 is the same as the example of FIG. 1, and the description thereof will be omitted. On the other hand, in the embodiment of FIG. 7, the lower end of the elevating cord 5 is not locked to the shade 2, and the weight 11 is attached to the lower end of the elevating cord 5. The weight 11 is larger than the ring of the guide ring 6 and has a size that cannot pass through the guide ring 6. Further, the weight 11 is attached to the lower end of the elevating cord 5 below the lowermost guide ring 6. The shape and material of the weight 11 can be selected and used from a known weight used in the shade, and is not particularly limited.

By attaching a weight to the lower end of the elevating cord, the elevating cord hangs vertically, so the force that pulls the shade backward is stronger than when the lower end of the elevating cord is locked to the shade, and the shade and window. This is preferable because the frame is more easily abutted. Also, when the shade is lowered to the bottom, the load of the weight is applied to the elevating cord and tension is applied to the elevating cord, so that the lower end of the shade is stable and the shade is difficult to separate from the window frame. When raising the shade, the weight first rises as the lifting cord is wound up. Then, when the weight rises to the position of the bottom guide ring, the weight cannot pass through the bottom guide ring, so the weight and the bottom guide ring are integrated and pulled up further while lifting the shade. ..

FIG. 8 is a schematic view showing the back surface of the raised shade of FIG. 7. The lift-up shade shown in FIG. 8 is provided with five elevating cords 5, but weights 11 are attached only to the elevating cords 5 at both left and right ends, and the lower end of the central elevating cord is shaded via a cord ring 7. It is locked to 2. According to such a configuration, a force that pulls the shade backward is strongly exerted at the left and right ends of the shade, and the shade and the window frame are surely in contact with each other. This is preferable because it is possible to reliably lift up from the lower end.

In the lift-up shade of the present invention, a known structure can be appropriately selected and used for the structure other than the support member. For example, the elevating mechanism may be a cord type, a drum type, or another mechanism. The shade is not particularly limited, and may be a voile fabric, a shade of a drape curtain fabric, or a shade of a blackout curtain fabric. Further, it is also preferable that each configuration of the elevating cord, the operation cord, the support member, and the like is provided with a safety mechanism such that the engaging portion is released and separated when a load of a predetermined value or more is applied.
