Description

  The present invention relates to a curtain rail having flexibility and a curtain set using the curtain rail, and more particularly to a curtain rail having high flexibility and a wider selection range of an installation place and a curtain set using the curtain rail.

  FIG. 5 is a side view of a conventional curtain rail 7 attached to a window 8 protruding from a car. As shown in the figure, a conventional pair of upper and lower curtain rails 7 are bonded to a window frame 82, and the curtain 70 is moved through a plurality of runners (not shown) that can slide along the upper and lower curtain rails 7. It is stretched between the pair of curtain rails 7 so as to be deployed / stored. Such a curtain rail 7 is made of a flexible material such as a resin so as to correspond to various window frames having different shapes depending on the design, for example, a bent portion of the window frame 82 in the drawing.

  FIG. 6 is a cross-sectional view of one pair of upper and lower curtain rails 7 bonded to the window frame 82. As shown in the figure, the curtain rail 7 has a web portion 71 having a bonding surface that adheres to the surface 81 of the window frame 82 in a manner similar to a groove-shaped cross section, and faces the window frame 82 from both sides of the web portion 71. The flange portion 72 is stretched, and the return edge is further stretched opposite the flange portion 72. The web portion 71 and the pair of left and right flange portions 72 define a rail space 73 having an opening therebetween. The plurality of runners can slide in the rail space 73, and the sliding of the runner enables the curtain 70 attached to the runner to be deployed / stored.

  However, as shown in FIG. 6, the structure including the web portion 71 and the pair of left and right flange portions 72 of the curtain rail 7 is designed in consideration of its structural strength. The flexibility of the rail 7 is impaired, and it is not always possible to ensure flexibility that can cope with all the bent portions of various window frames.

  Furthermore, the web portion 71 is not necessarily completely compatible with the surface 81 of the window frame 82. For example, in the case where the surface 81 is a curved surface as shown in the drawing, if the web portion 71 is a flat surface, the area where both are bonded is considerably limited. If the area to be bonded is insufficient, sufficient adhesive force cannot be obtained, and the curtain rail 7 bent according to the bent portion of the window frame 82 using its flexibility returns to its original shape and the appearance is impaired. The curtain rail 7 can be easily detached from the window 8 in the worst case.

  If the web portion 71 is forced to bend to match the curved surface of the surface 81 by using the flexibility of the curtain rail 7 in order to increase the area to be bonded, the opening between the flange portions 72 on both sides is on the contrary. It is clear that the runner that slides in the rail space 73 due to excessive opening will be disengaged from the excessive opening.

  Therefore, in view of the problems of the conventional flexible curtain rail, the present invention can improve the flexibility, and can solve the problem of mounting a curved surface or a place with a step, It is an object of the present invention to provide a curtain rail having a wide selection range of mounting locations, and a curtain set using the curtain rail.

  In order to solve the above problem, the curtain rail of the present invention is made of a thin flat base extending along the length direction of a flexible material and one surface of which is a sticking surface. And a rail main body protruding integrally with the base in the width direction on the other surface of the base across the direction, and the base has a wing portion on the left and right over the entire length by a base connected to the rail main body. Provided is a curtain rail characterized by

  In particular, it is preferable that a plurality of notches are formed in the two wing portions of the base at regular intervals over the entire length.

  In addition, the rail body can be configured to have an abdomen connected to the base and a pair of projecting edges that protrude from the tip of the abdomen to both sides in the width direction over the entire length.

  In addition, the rail body extends from the base to a curved surface having a semicircular cross section on both sides in the width direction over the entire length, and then both end edges that are separated from each other in diameter are bent toward the center so as to face each other. An opening having an appropriate width may be formed, and the runner may be configured to have a pair of slide rail portions that can be engaged through the opening and can slide along the length direction.

  Furthermore, it is preferable that the curtain rail further includes a pair of end caps attached to both ends in the length direction so that the sliding runner does not fall off the rail body.

  The present invention also provides a curtain set including the curtain rail configured as described above, a plurality of runners slidably engaged with the rail body, and a curtain hooked on the plurality of runners.

  The present invention improves the flexibility of the base, which is the bonding part of the curtain rail, and also reduces the influence of the rail body when bending, so the flexibility of the material can be fully preserved without interfering with the function of the rail body It is possible to provide a curtain rail that can be exerted and reliably adhere to a place where mounting is difficult, such as a curved surface or a step, and a curtain set using the curtain rail that has a much wider selection range of the mounting place can also be provided. .

  FIG. 1 is an exploded perspective view of the first embodiment of the present invention. Shown in the figure is a curtain rail type curtain set 10 for a vehicle window, that is, a curtain set using the curtain rail of the present invention.

  As illustrated, the curtain set 10 includes a curtain rail 1, a plurality of runners 3, a curtain 2, and two caps 4.

  The curtain rail 1 is made of a flexible material such as resin and extends along its length direction. One surface of the curtain rail 1 is formed as a tensioning surface 110 in a plane, and the back side of the tensioning surface 110 is disposed on the back side. The rail body 12 is formed and formed on the base 11 along the length direction.

  The base 11 is formed in a thin flat plate shape, and has a base portion 111 connected to the rail 12 main body, and wing portions 112 and 112 extending from the base portion 111 in the left-right width direction in the length direction. is doing. In addition, a plurality of triangular cutouts 113, 113, 113,... Are formed in the wing portions 112, 112 so as to be separated from each other at a predetermined distance and symmetrically. Further, when the double-sided tape 5 is attached to the attaching surface 110, the curtain rail 1 and the curtain set 10 can be attached to a required installation location, for example, a window frame of a car window.

  The rail body 12 includes an abdominal part 121 connected to the base 11 and a pair of slide rail parts (protruding edge parts) 122 and 122 that protrude in the left-right width direction from the distal end of the abdominal part 121 in the length direction. Have.

  Each runner 3 has a curtain hook portion 32 that slidably suspends the curtain 2 on the slide rail portions 122 and 122 of the rail body 12, and runner hook portions 31 and 31 that engage with the rail body 12 from both sides. ing. As illustrated, the runner hook portions 31, 31 have a pair of left and right hook blocks 311, 311. The pair of left and right hook blocks 311 and 311 are inserted into the upper surface of the slide rail portions 122 and 122 of the rail body 12 from both sides, so that the runner 3 can slide the slide rail portion 122 along the length direction.

  In the vicinity of one side edge of the curtain 2, eyelets 211, 211, 211,... Corresponding to the number of runners 3 are provided. Each of the eyelets 211 is hooked on the curtain hook portion 32 of each runner 3, and the slide rail portions 122 of the rail body 12 are arranged in the order of eyelets 211, 211,. , 122 allows the curtain 2 to be deployed / stored by sliding on the slide rail portions 122, 122 of the runner 3. Alternatively, the eyelets 211 may be provided near the peripheral edges of the opposite sides of the curtain 2. In this case, it is necessary to prepare curtain rails corresponding to the both sides, for example, a pair of upper and lower curtain rails or a curtain rail having a sufficient length, and a number of runners corresponding to the number of eyelets 211. When using a pair of upper and lower curtain rails, the curtain is deployed / stored between the pair of upper and lower curtain rails as in the conventional curtain set.

  The two end caps 4, 4 are attached to both ends of the curtain rail 1, that is, both front and rear ends in the length direction. After the runner 3 is engaged with the rail body 12, the end caps 4 are attached to the both ends. As a result, the sliding of the runner 3 is limited between the two end caps 4, 4, and there is no possibility of falling off from the rail body 12.

  2 shows the curtain set 10 of the present invention having the above-described structure attached to the window frame 62 for a vehicle window, and FIG. 3 shows a cross section when the curtain set 10 is attached to a curved surface. FIG. The attachment method will be described with reference to FIGS.

  Incidentally, the window frame 62 for vehicle windows generally has a saddle curved surface 621, and when the conventional curtain rail 7 is attached to the saddle curved surface 621, the contact area between the two is insufficient as shown in FIG. It becomes unstable installation.

  First, as shown in FIG. 2, the entire curtain rail 1 is bent and matched with the outline of the window frame 62. Then, as shown in FIG. 1, one surface of the double-sided tape 5 is attached to the attaching surface 110 that covers the entire width of the two wing portions 112, 112 of the curtain rail 1, and the two portions of the curtain rail 1 are attached as shown in FIG. The two wings 112, 112 are bent and attached to the entire other surface of the double-sided tape 5 according to the curved surface 621 of the window frame 62.

  Subsequently, each eyelet 211 of the curtain 2 is hooked one by one on the curtain hook portion 32 of each runner 3, and then the runner 3 is placed in the order of the eyelets 211, 211, 211, 211. The slide rails 122 and 122 are engaged. Finally, if the two caps 4 and 4 are attached to both ends of the curtain rail 1, the attachment of the curtain set 10 of the present embodiment to the window frame 62 is completed.

  When the curtain rail 1 is attached to the window frame 62, whether or not the curtain rail 1 can sufficiently correspond to the outline of the window frame 62 is determined by the flexibility of the curtain rail 1 as a whole. In both the curtain rail 1 of the present embodiment and the conventional curtain rail 7, when bent to both sides in the length direction, the peripheral edge on one side is stretched and the other side is compressed. And when curving to both sides, the resistance to stretching and compression on both sides must be overcome. Furthermore, the wider the object to bend, for example, the curtain rail 1 of this embodiment (or the conventional curtain rail 7), the greater the amount of change in stretching and compression on both sides thereof, and the resistance to be overcome also changes. Become stronger according to the amount.

  When FIG. 1 is compared with FIG. 6, the curtain body 1 is formed at the center portion of the curtain rail 1, unlike the flange portion 72 formed on both sides of the conventional curtain rail 7. . The web portion 71 having the base 11 of the curtain rail 1 and the adhesive surface of the conventional curtain rail 7 is, for example, the same material (ie, its own flexibility) and thickness, and overcomes when bent. Even if the resistance to be applied is the same, the rail body 12 at the center of the curtain rail 1 and the pair of left and right flange portions 72 of the curtain rail 7 have different amounts of change when bent due to the difference in position. Since the flange portions 72 on both sides are more severe, the resistance to be overcome even though both the forming material and the thickness of the rail body 12 at the center portion of the curtain rail 1 and the pair of left and right flange portions 72 of the curtain rail 7 are the same. The pair of left and right flange portions 72 of the curtain rail 7 is stronger than the rail body 12 at the center of the curtain rail 1. That is, when performing similar folding, the curtain rail 1 of the present invention has a smaller resistance than the conventional curtain rail 7, and conversely, when bending with the same force, the curtain rail 1 of the present invention. Since the resistance to be overcome is smaller, it can be bent more greatly. That is, the structure of the curtain rail 1 of the present invention has more excellent flexibility. By the way, in the present invention, it is also possible to improve the flexibility of the entire curtain rail 1 by forming the base 11 and the rail body 12 connected to each other (the base 111 and the abdomen 121) narrowly.

  Furthermore, a plurality of triangular notches 113 are formed symmetrically on the base 11 of the present invention. When affixing the curtain rail 1 of this embodiment, it is preferable to install the notch 113 corresponding to a portion having the largest amount of bending, such as a window frame. As a result, the amount of change in stretching and compression on both sides (two wings 112, 112) of the base 11 itself is remarkably relieved when bending, so that the effect of increasing the flexibility of the entire curtain rail 1 can be brought about. It can be pasted nicely according to the curved parts such as window frames.

  Also, whether the tensioning surface 110 of the curtain rail 1 can sufficiently correspond to the curved surface 621 of the window frame 62 is determined by the flexibility of the two wing portions 112, 112 of the entire base 11. Since the base 11 of the present invention is formed thin, the base 11 can be stretched over the entire surface in accordance with the curved surface 621 of the window frame 62 by utilizing its flexibility. As a result, the contact area between the curtain rail 1 and the window frame 62 can be increased, the sticking thereof becomes stronger, and a stronger force can be obtained to overcome the resistance generated when bending. By the way, if the web portion 71 of the curtain rail 7 is formed to be thin in the same manner, it can be stretched over the entire curved surface in the same way, but in that case, a pair of both sides provided on both sides Since the opening between the flange portions 72 is too open, which interferes with the engagement of the runner, it is not recommended to apply the entire width.

  Moreover, the curtain rail 1 of this embodiment can be provided in a pair of upper and lower like the conventional curtain rail, and in this case, the additional curtain rail can also provide excellent flexibility and strong fixing property. it can.

  Moreover, the curtain rail 1 of this embodiment is not only a saddle curved surface, but also a flat surface (or a loosely undulating arc surface) that can correspond to the base 111 connected to the rail 12 main body even if the contact surface has an obstacle such as a step. ) Can be secured, it is possible to obtain a strong fixability by making use of the flexibility of the wing portions 112, 112.

  Furthermore, even when the curtain set 10 of this embodiment is installed on the rear glass of an automobile, the curtain rail 1 can be bent by using its excellent flexibility, and can be attached to avoid the high mount brake lamp. It can be installed nicely without disturbing the function of the brake lamp.

  FIG. 4 is an exploded perspective view of the second embodiment of the present invention. Also shown in the figure is a curtain rail type curtain set 20 for a vehicle window, and the difference from the first embodiment is the configuration of the rail body 12A and the runner 3A corresponding thereto. Moreover, the same code | symbol is attached | subjected to the location which has the same structure as 1st Embodiment, and the description is abbreviate | omitted.

  As shown in the figure, the curtain set 20 is also composed of a curtain rail 1A, a plurality of runners 3A, and the curtain 2, and illustration of the cap is omitted.

  In this embodiment, the rail body 12A is bent so as to form a semicircular cross section in the left-right width direction over the entire length from the base 11, and then a pair of diameter ends bent toward the center. The slide rail portions 122A and 122A are provided, and an opening is provided between the pair of slide rail portions 122A and 122A for a reciprocating runner 3A to be described later.

  Each runner 3A is provided with hook blocks 311A, 311A and a curtain hook portion 32A at both ends of the shank 30 to be engaged with the rail body 12A. As shown in the drawing, a pair of left and right hook blocks 311A and 311A are projected from one end of the shank 30. The pair of left and right hook blocks 311A and 311A are placed on the slide rail portions 122A and 122A of the rail body 12A through the opening by the shank 30, so that the runner 3A can move the slide rail portions 122A and 122A along the length direction. You can slide on top.

  The second embodiment also has all the advantages of the first embodiment, and can obtain excellent flexibility and strong fixing properties.

  In addition, the application range of the present invention is not limited to those for car windows, but curtain sets used in trains, buildings, etc. can be used as long as they use curtain rails. A curtain set using can be used.

  The curtain rail of the present invention having the above-described configuration and the curtain set using the curtain rail improve the flexibility of the base, which is the bonding portion of the curtain rail, and also reduce the influence on the rail body when bending. It is possible to provide a curtain rail that can fully adhere to difficult-to-mount places such as curved surfaces and steps, making the material flexible without disturbing the function of the material, and the range of choice of the mounting location has become much wider It is also possible to provide a curtain set using the curtain rail.
