Description

  The present invention relates to a shade in which a lifting / lowering cord for lifting / lowering a shade fabric is eliminated.

  Conventionally, blinds are installed in windows of buildings such as buildings and houses to shield light and human eyes. A typical blind is a substantially flat slat that extends in the horizontal direction and hangs up and down through a plurality of right and left lifting cords, and each slat is centered on its horizontal longitudinal axis. As a result, the gap between each slat can be opened and closed. Further, by pulling up the lowermost slat with an elevating cord, the upper slats are pulled up while being stacked one after another, so that the entire blind can be opened and closed (for example, Patent Document 1).

  On the other hand, in recent years, a roman shade using a cloth shade has been developed instead of a blind using a conventional slat (for example, Patent Document 2). In this type of roman shade, a shade fabric made of a single piece of cloth is suspended from a head box at the upper end containing a roller or the like for guiding the raising / lowering operation of the raising / lowering cord, and a bottom bar is arranged at the lower end of the shade fabric. ing. From the head box to the bottom bar, a plurality of right and left lifting cords are arranged in a state of being inserted through the shade fabric at a predetermined pitch. Then, the Laurent shade can be opened and closed by pulling the bottom bar upward by the lifting cord and expanding and contracting the shade fabric as a whole while being folded in a plurality of stages. In addition, a roll blind that winds and stores the entire shade fabric in a head box without using a lifting cord has been developed (for example, Patent Document 3).

  By the way, since the blinds and shades are installed in the interior of a building, the design of the indoor space is greatly affected. However, conventional blinds and roman shades have not been studied much about the design properties given to indoor spaces. In roman shades and roll blinds using shade fabric, it is possible to improve the design in the fully closed state by attaching a pattern or woven pattern to the shade fabric itself, but in the half-open or fully-open state, the design is Lost. When the Roman shade is half-opened or fully opened, the shade fabric is folded in multiple stages up and down, but since the lifting cord is only inserted at a constant pitch, the folded state is always constant. It is impossible to improve the performance. In the blind, the slats simply overlap each other, and it is impossible to improve the design in a half-open or fully-open state. That is, the conventional blinds and roman shades that are opened and closed by the lifting / lowering cords cannot improve the design properties due to the overlapping state, including the half-open or fully-open state.

  Further, the conventional blind and roman shade have a configuration in which a head box incorporating a roller and the like for guiding the lifting / lowering cord, and a bottom bar are indispensable in addition to a lifting / lowering cord for raising / lowering or expanding / contracting each slat and shade fabric. In this case, the number of parts is large, and assembly work (manufacturing) is complicated. Although roll brands do not use lifting cords, the head box and bottom bar that winds and stores shade fabric are still essential.

  In addition, since the left and right width dimensions of the head box and the bottom bar are not variable, the versatility is poor. The left and right width dimensions of blinds and roman shades are often designed to have various standard dimensions in accordance with standardized building windows. Therefore, it is usually sufficient to purchase a roman shade having a width according to the window. However, if the width of the window to be installed changes due to renovation or moving of the building, it has conventionally been necessary to purchase a new roman shade or the like again in accordance with this. Further, the conventional roman shade or the like is for fixing the head box to the existing curtain rail, but this requires complicated installation work.

  SUMMARY OF THE INVENTION Accordingly, the present invention is to provide a shade that can change various folding shapes of shade fabrics, has high designability, has a simple configuration and high versatility, and eliminates a lifting / lowering cord.

  As a means for this, the present invention is a shade that opens and closes by expanding and contracting the shade fabric up and down, and is not provided with an elevating cord, and a male member that can be engaged and disengaged from the top to the bottom of the shade fabric A plurality of engaging means including female members are provided in a row. That is, in this invention, it replaces with the conventional raising / lowering code | cord | chord, and becomes a structure which expands / contracts a shade fabric by the some engaging means which consists of a male member and a female member. According to this, the folding shape of a shade fabric can be freely changed by changing various engagement positions of a plurality of male members and female members. In other words, there are many variations in the folded shape of the shade fabric, and shapes of all designs can be formed. Moreover, if the folded state to some extent is set to the fully closed state, not only the design property in the half-open or fully-open state but also the design property in the fully closed state can be improved without using a design or the like. Thereby, the designability of a shade and by extension, the designability of indoor space can be improved.

  Further, since the shade according to the present invention does not include the lifting / lowering cord, the head box and the bottom bar that are essential in the conventional blind, the roman shade, and the like are not necessarily required. Therefore, a shade having a simple configuration with a small number of parts can be obtained.

  It is preferable that the male member and the female member are regularly arranged at regular intervals. In addition, the fixed space | interval here means the space | interval of male members and female members. Therefore, a plurality of female members may be disposed between the male members, and conversely, a plurality of male members may be disposed between the female members. Preferably, the male member and the female member are arranged alternately. Thus, if the male members and the female members are regularly arranged at a constant interval, a certain regularity also occurs in the shade folded shape. That is, since the folded portions of the shade fabric having a plurality of stages are arranged in an orderly manner, the design can be further improved.

  For example, the engaging means may be provided in only one row at the center in the left-right width direction of the shade fabric, but it is preferable to provide a plurality of rows on the left and right. Thus, for example, in a shade having a relatively large width, it is possible to prevent collapse of the folded shape, and further, the engagement positions (engagement patterns) of the male member and the female member in each row are made different from each other. As a result, the variation of the folded shape further increases, and the design can be further improved.

  The engaging means may be, for example, a hook as a male member and an engaging hole as a female member, or a snap button including a male button and a female button. In the case of a snap button, the male button and the female button can be easily engaged, and the male button and the female button can be easily detached simply by pulling the shade fabric downward.

  The engaging means may be provided directly on the shade fabric, but it is preferable to provide the engaging fabric on the elongated fabric in advance and then provide the base fabric on the shade fabric. According to this, it is easy to install the engaging means, and it is possible to avoid variations in the arrangement interval of the engaging means for each product.

  The engaging means may be disposed on the surface of the shade fabric, but is preferably disposed on the back surface. According to this, the presence of the engaging means can be made inconspicuous in the fully closed state of the shade, and adverse effects on the designability in the fully open state can be suppressed. Even if the engagement means is arranged on the surface of the shade fabric, the engagement means is hidden by folding the shade fabric as long as the engagement means is engaged.

  It is preferable that the upper end edge of the shade body is provided with a cylindrical portion through which a support rod for hanging and supporting the shade fabric can be inserted. As described above, the conventional head box is not necessary in the present invention. Therefore, if a cylindrical portion is provided instead of this, it is only necessary to insert a support rod into the cylindrical portion, so that the number of components is small and the configuration is simple, and the installation of the shade is facilitated. The support rod is not particularly limited as long as it is a rod member that can be inserted into the cylindrical portion and can support the shade in a suspended manner. And since the cylinder part is also formed of the cloth, the shade itself can be expanded and contracted in the width direction and is highly versatile. That is, when installing in windows having various width dimensions, the shade cloth can be adjusted to the width dimension of the window by expanding and contracting in the width direction. At this time, a support bar having a length corresponding to the width dimension of the window is used. However, if the support bar itself is also extendable, it is preferable that the support bar need not be sequentially changed.

  According to the present invention, the shade fabric is vertically expanded and contracted by a plurality of engaging means composed of a male member and a female member that can be engaged with and disengaged from each other instead of the conventional lifting cord. Can be designed sequentially and freely, and the design can be improved. Further, a conventional head box, bottom bar, or the like is unnecessary, and a highly versatile shade can be obtained with a simple configuration.

  Hereinafter, exemplary embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited to these embodiments, and various modifications can be made without departing from the scope of the present invention. The shade of the present invention is typically applied to windows of various buildings such as buildings, houses, shops, and public facilities, and entrance / exit windows to the outside in order to shield light and human eyes. Moreover, it can also be provided on the wall as an interior because of its high design.

  As shown in FIG. 1, the shade 1 is a shade fabric 10 that covers a window and fulfills the original function of the shade, a plurality of snap buttons 20 that stretch and hold the shade fabric 10 in the vertical direction, and supports the shade fabric 10 in a suspended manner. It is comprised by the support rod 30 to do. Note that the conventional lifting / lowering cord, head box, and bottom bar are not provided. The snap button 20 corresponds to the engaging means of the present invention.

  The shade fabric 10 is made of a flexible single sheet. In addition, the upper end edge of the shade fabric 10 is integrally formed with a hollow cylindrical tube portion 11 having both left and right ends opened by folding back the upper end portion of the shade fabric 10. The shade fabric 10 is a natural fiber such as cotton or hemp, a synthetic resin fiber such as polyethylene or polyester, or a woven fabric using a mixture of natural fiber and synthetic resin fiber.

  As shown in FIG. 2, the snap button 20 includes a male button 21 and a female button 22 that can be engaged and disengaged with each other. Each male button 21 and female button 22 are joined in advance to an elongated tape-like base cloth 23 by sewing, bonding or the like. In addition, the base fabric 23 is sewn up and down on the back surface of the shade fabric 10. Thereby, on the back surface of the shade fabric 10, as shown in FIG. 1, a plurality of snap buttons 20 are provided in a row from the top to the bottom. The male buttons 21 and the female buttons 22 are alternately provided vertically at equal intervals, so that the male buttons 21 and the female buttons 22 are regularly arranged at regular intervals. . In this embodiment, the snap buttons 20 are provided in three rows at the left and right side edges and the width direction center of the shade fabric 10.

  The support rod 30 suspends the shade fabric 10 by being inserted through the tube portion 11. The support rod 30 is not particularly limited as long as it is a rod member having a thickness that can be inserted into the cylindrical portion 11, a length that is larger than the width of the shade fabric 10, and a strength that can withstand the weight of the shade fabric 10. A metal bar, a wooden bar, a resin bar, a ceramic bar, etc. can be used. In addition, stoppers 31 are provided at both ends of the support bar 30. As such a support rod 30, for example, a so-called “stretching rod” commercially available from a mass retailer or the like is suitable. In this embodiment, a “stretching rod” as shown in FIG. 3 is used, which can be expanded and contracted by rotating the inner rod with an inner / outer double structure so that it can accommodate windows of various sizes. ing.

  In order to install the shade 1 in the window, the support rod 30 is inserted into the cylindrical portion 11, and the length of the support rod 30 is adjusted to the width dimension of the window frame (not shown) as necessary. It is only necessary to install the rod 30 at the upper end inside the window frame. At this time, the support rod 30 is firmly installed in the window frame by the left and right stoppers 31 to prevent sliding off.

  In order to open and close the shade 1, the length of the shade fabric 10 may be expanded and contracted by appropriately engaging and disengaging the snap button 20. In this embodiment, since the snap button 20 is used as the engaging means, when the shade 1 is closed from the opened state, it is only necessary to pull the shade fabric 10 downward. In the state where the shade 1 is opened, the shade fabric 10 is folded at the position of the engaged snap button 20. If the snap buttons 20 are engaged at a plurality of locations, the snap button 20 is folded in a plurality of stages. In addition, by changing the number of engagements of the snap buttons 20 and the combinations of the male buttons 21 and the female buttons 22 and the like, the folding shape of the shade 1 can be variously designed. In the present invention, since the folding shape of the shade 1 can be variously changed, the fully open state of the shade 1 is not uniquely defined. Hereinafter, the portion where the shade fabric 10 is folded is referred to as “襞”.

For example, when all the snap buttons 20 (all adjacent male buttons 21 and female buttons 22) are engaged, as shown in FIG. 4, a large number of small folds are overlapped. Further, if the snap button 20 is engaged every other one or a plurality, a relatively large ridge is formed as shown in FIG. Further, as shown in FIG. 6, the snap button 20 may be engaged only at the upper and lower intermediate portions of the shade fabric 10. The shapes shown in FIGS. 4 to 6 have the same engagement pattern of the snap buttons 20 in each row. Therefore, each ridge extends flat in the left-right direction.

  Furthermore, by changing the engagement pattern of the snap buttons 20 in each row, for example, as shown in FIG. 7 or FIG. For example, the snap buttons 20 in the rows on the left and right side edges engage every other row, while the snap buttons 20 in the row in the center in the width direction engage every other row. There are a variety of engagement patterns that are the same but have different height positions for engagement. In order to form a beautiful folded shape, it is preferable that the engagement patterns of the rows on the left and right side edges are the same.

  When the width dimension of the window to be installed is changed due to renovation or moving of the building, the width dimension of the shade fabric 10 is expanded and contracted as shown in FIG. The same shade 1 can be used as it is. FIG. 9 shows a state in which the shade 1 having a width dimension larger than that of the window is installed in a state where the shade fabric 10 is brought close together in the width direction. In this case, since the wrinkles become three-dimensional by wrinkling in the width direction, the design can be further improved.

(Modification)
In the above embodiment, three rows of snap buttons 20 are arranged in parallel on the left and right side edges and the central part. However, when using a shade fabric 10 having a large width dimension, for example, as shown in FIG. It is also preferable to arrange a plurality of rows of snap buttons 20. In this case, if the same engagement pattern is used in even rows and odd rows, it is easy to form a beautiful design. As long as the shade fabric 10 has a relatively small width, only two rows on the left and right side edges or only one row at the center may be used. Further, when the snap buttons 20 are arranged in a plurality of rows, the snap buttons 20 are not necessarily provided on the left and right side edges.

  The shade fabric 10 basically has the same length as the height of the window, and the fully extended state in which all the snap buttons are detached may be in the fully closed state. Without being limited thereto, the shade fabric 10 having a length dimension larger than the height dimension of the window may be used to make the state folded to some extent a fully closed state.

  In the above embodiment, the male buttons 21 and the female buttons 22 are alternately arranged. However, the present invention is not limited thereto, and a plurality of female buttons 22 are arranged between the male buttons 21 or a plurality of female buttons 22 are arranged between the female buttons 22. The male button 21 can also be arranged.

  As the engaging means, in addition to the snap button 20 including the male button 21 and the female button 22, for example, a hook as a male member and an engaging hole as a female member can be used. The engaging means can also be provided directly on the shade fabric 10. Further, the engaging means can be provided on the surface of the shade fabric 10.

  The cylindrical part 11 can also sew a cylindrical member formed of a separate cloth on the upper edge of the shade fabric 10. When the shade 1 is installed, a support bar that does not have the stopper 31 may be simply placed on the curtain rail. In the present invention, the head box and the bottom bar are basically unnecessary because the lifting cord is not used. However, for example, a head rail for installation and fixing to the curtain rail can be provided instead of the cylindrical portion 11. Moreover, you may dare to use a bottom bar.
