Description

  The present invention relates to a structure of a slat with a pressure contact portion sold as a single product, and a blind which a plurality of slats are held in pressure contact with a facing wall of a window frame at a predetermined interval and assembled by a purchaser himself according to his / her preference. This pressure contact portion is composed of, for example, a commercially available tension rod.

  Blinds that are installed in windows and used for shielding adjustments such as sunlight and peeping are classified into horizontal blinds in which slats hang down in the horizontal direction and vertical blinds in which slats hang down in the vertical direction. The horizontal blinds are used by holding the slats horizontally and opening and closing them by the action of a plurality of ladder cords suspended vertically from the head rail. The vertical blind is used by opening and closing a slat that hangs continuously from the head rail. Both horizontal blinds and vertical blinds function as blinds integrated with slats, operation rods, ladder cords, and head rails. The blind is usually connected to a connection member (bracket) fixed to one side of the window frame, and is installed in a state of covering the entire window.

  In these conventional blind installation methods, the head rail portion is fixed to a bracket that is screwed to a desired location using a screwdriver or the like. Since the blind covers the entire window opening, the number of slats required is proportional to the increase in the opening area. However, the number of slats constituting a general blind is determined in advance at the time of manufacture, and it is generally difficult for the purchaser to adjust the number of slats on site according to the opening area of the window where the blind is installed. However, it is not common to distribute only the slats and assemble the blinds by themselves.

  Furthermore, the method of connecting to the bracket when installing the blind is easy to detach and attach during maintenance once the bracket is installed, but a tool such as a screwdriver is required and the installation location is often high. It is generally difficult for a typical purchaser to easily install a blind. Also, since the slats cover the entire window, the number of sheets is large, and the material is made of thin metal plates or cloth, so maintenance such as cleaning is delicate and it is difficult for general purchasers themselves to perform this maintenance work as if they were DIY. is there. Furthermore, since all the slats are configured to be opened and closed at the same angle at the same time, it is impossible to perform partial opening and closing operations and partially perform shielding adjustment. Further, when the window is opened for the purpose of ventilation, the slats are beaten by the influence of the wind, and the collision sound with the adjacent sash and the like is uncomfortable, and there is a structural defect that causes both scratches.

  As a solution to these existing blind problems, for example, in Japanese Patent Laid-Open No. 2014-043707 or Japanese Patent Laid-Open No. 2004-225397, slats are passed through guide cords installed in the vertical direction from the vicinity of the left and right ends of the blind main body to suppress the sag. Blind aiming at the effect is released. In addition, by installing a member that sandwiches the bottom rail only at the lowermost position at the lower end of the installation part in advance, there are things aiming at the anti-turning effect, but both need to newly install a guide cord and anti-turning member, Installation is complicated and troublesome. Japanese Patent Laid-Open No. 2009-235670 or Japanese Patent Laid-Open No. 2005-120612 discloses blinds that can partially set the opening / closing range of the slats, but the opening / closing range is limited, so only the range intended by the user is disclosed. There is no disclosure of adjusting the shading or sunshine.

  Further, Japanese Utility Model Laid-Open No. 6-57280 discloses a roll curtain installed on a window frame or the like. The roll curtain is configured to fix the roll curtain to the window frame with a stick, and also functions as a blind. However, even in this configuration, the window opening is not yet configured to shield only the range intended by the purchaser. In addition, Utility Model Registration No. 3090006 discloses a louver fitting that is easy to attach and detach and attach to a support column. However, since the louver fitting itself is composed of a certain size, only the range intended by the purchaser is disclosed. It is not a shielding structure. Furthermore, Japanese Patent Laid-Open No. 2003-183362 discloses a simple attachment type curtain that is attached to a tension rod, but this also has a predetermined curtain size and is not configured to freely change the shielding range.

  That is, in any reference, the main technical idea of the present invention that “sells a slat as a single product and assembles a blind with a slat as a single product purchased by a purchaser himself” is not disclosed, Either reference only discloses a configuration for blinds or louvers with slats already assembled.

  As described above, the slat part of the blind according to the prior art sells the slat as a single product, and the purchaser himself assembles the blind with the slat as a single product purchased in a DIY sense. It is not based on slats. That is, a conventional slat does not function unless it is integrated with a head rail having an operation function together with an operation rod, a ladder cord, and the like, and does not have a structure that functions as a single slat. Moreover, the size of the existing blind is determined at the time of manufacture, and the purchaser himself cannot set the size freely according to the size of the window frame at the installation site of the blind. Furthermore, the opening and closing angles of the slats can be set only uniquely for all the slats, and each slat cannot be set individually. Furthermore, the design impression of the entire blind is simple, poorly changed, and has a drawback of receiving a cold impression.

  The present invention discloses a slat with a press contact portion as a single product having a strip shape for a blind. The feature of this slat is composed of two parts: a blade part for shielding light and a pressure contact part provided at both ends of the short side of the blade part to press and hold the blade part in a vertical direction or a horizontal direction on opposite walls of the window frame. It has been done. The pressure contact portion uses a commercially available stretchable rod or screw mechanism, and is provided with a penetrating tube portion that accommodates the rod or the screw mechanism biased in the long side direction of the blade portion. Yes. And since this blade | wing part can be axially rotated by the center axis | shaft of the tension rod or screw mechanism accommodated in the penetration cylinder part, a slat opening-and-closing angle can be adjusted individually by manual rotation operation. . In addition, the planar shape of said blade | wing part is free, and the blade | wing part is comprised so that a free plane design can be added.

  Further, in the present invention, the purchaser of the slat with a press contact portion as the single product itself is a DIY sense, and arranges the slats with the press contact portion by an arbitrary number according to the distance between the opposing walls of the window frame. It is possible to assemble the blind according to preference by holding it in pressure contact with the opposing side walls by the pressure contact portion. In this case, adjacent slats may be regularly separated and connected by a connecting pin.

  Furthermore, when the slat with a pressure contact portion of the present invention is manufactured with a material that can be easily cut with, for example, scissors, and the length of the blade portion of the blind is too longer than the window frame width, a part of the blade portion with the scissors The cut-out length can be adjusted. On the other hand, when the length is too short, the cylindrical extension blade portion sandwiched in a sandwich shape from the front and back of the short side end portion of the blade portion can be moved forward and backward to extend the length.

  Since the slats with pressure contact portions according to the present invention are products that are independent of each other, the purchaser only needs to purchase slats having an arbitrary interval and a range corresponding to the size of the window frame. It is possible for the purchaser to assemble the blinds according to his / her preference by arranging them in parallel and press-contacting them against the opposing wall of the window frame. In addition, the opening / closing angle can be adjusted by rotating only the slats at any point or range, and the desired shielding adjustment effect can be obtained. The mounting method is the same as that of a commercially available tension rod, and can be easily installed without the need for tools. Furthermore, it is possible to install a horizontal bar or a vertical direction by pressing a stick between the opposing walls of the window frame, and it is convenient for installation in rental housing, especially when there is no screw mark. As described above, the slat with a pressure contact portion of the present invention has an advantage that the work can be efficiently performed at the time of installation.

  Furthermore, in the blind according to the present invention, each slat itself is independent, and if only the number required by the user is purchased, the cost is not wasted. Further, each slat has an advantage that it is easy to perform maintenance such as cleaning because it can be easily detached.

  Furthermore, the slat with a pressure contact portion of the present invention is not simply suspended like a conventional blind, but is held in pressure contact with the opposing wall of the window frame while maintaining a predetermined opening / closing angle, so that the influence of wind Even if it receives it, it is not beaten, and there is an advantage that there is no anxiety of a collision sound and a flaw because there is no collision with a close fitting unlike a conventional blind.

  Furthermore, unlike the conventional product, this slat with a pressure contact part can be changed in color, pattern, material, shape, or composite by replacing the slats individually, which can easily add decorativeness. In addition, the purchaser can combine the favorite slats to make the blinds into a unique design, which has the advantage that the decorativeness can be improved.

  Furthermore, the slat with a pressure contact part according to the present invention can also be sold separately by separating the struts used for the blade part and the pressure contact part, and the purchaser can add paint or shape to the blade part. In addition, it is possible to make a slat with a pressure contact portion having an original design by a method such as using a variety of commercially available rods and rearranging them independently. Therefore, there is an advantage that the slats can be sold independently by a sales method different from the conventional blind.

  Furthermore, this slat with a pressure contact part can be manufactured to be long and cut to a length dimension as required, or extended by sliding the extension blade part. It has the advantage of meeting your needs.

FIG. 2 is a perspective view of a slat with a press contact portion according to the present invention in which a tension rod constituting the press contact portion is inserted into a through tube portion provided in a major axis direction of a blade portion. FIG. 3 is a perspective view of the slat with a pressure contact portion according to the present invention in which the tension rods constituting the pressure contact portion are inserted into the through cylinder portions respectively provided at both ends in the major axis direction of the blade portion. FIG. 4 is a front view of another embodiment of the press contact portion. FIG. 5 is a front view of still another embodiment of the pressure contact portion. FIG. 6 is a front view when the slat with a pressure contact portion according to the present invention faces the front. FIG. 7 is a front view when the blade portion of the slat with a pressure contact portion according to the present invention is rotated. FIG. 8 is a front view showing another shape blade portion of the slat with a pressure contact portion according to the present invention. FIG. 9 is a front view showing a blade part obtained by adding an arbitrary design to the slat with a pressure contact part according to the present invention. FIG. 10 is a front view showing a blind and a blind in which a plurality of slats with pressure contact portions according to the present invention are connected by a connection pin. FIG. 11 is a front view showing a slat with a press contact portion to which an extension blade portion is slidable in order to extend the length in the major axis direction of the slat with a press contact portion according to the present invention.

  FIG. 1 is a perspective view of a slat 1 with a pressure contact portion according to the present invention as viewed from the indoor side where a blind 100 is constructed by attaching a pressure contact portion 20 to a facing wall of a window frame facing in the vertical direction. In FIG. 1, a strip-shaped slat 1 with a pressure contact portion is configured to be pressed against an opposing wall of a window frame facing in the vertical direction to form a vertical blind 100. You may comprise so that the part 20 may be contact | abutted to the opposing wall of the window frame which opposes a horizontal direction, and it may become a horizontal blind. Moreover, although the blind 100 is comprised by the four slats 1 with a press-contact part in this figure, what is necessary is just to use the slat 1 with a press-contact part which concerns on this invention only for a required number according to a window frame size. In this way, unlike the conventional blind in which the size is determined at the time of manufacture, in the blind 100 according to the present invention, the purchaser of the blind has an arbitrary number of slats 1 with pressure contact portions according to the window frame size. Can be brought into pressure contact with the opposing wall of the window frame, so that the design is neat and the design flexibility is improved.

  Moreover, in the said structure, if the blade | wing part 10 is directly rotated by manual operation, it will also become possible to open / close each slat 1 with a press-contact part individually. Therefore, there is an advantage that only a necessary part of the outside light entering the room can be shielded, and in this respect as well, it is different from a conventional blind in which all slats are operated at the same opening / closing angle by, for example, a ladder cord. . In this figure, an example is shown in which the opposing wall of the window frame is provided only on the indoor side of the window. However, depending on the type of the window frame, the opposing wall may extend to the outside of the window. . In the case of such a type of window frame, it is also possible to place the blind 100 on the outside of the window by pressing the slat 1 with the press contact portion of the present invention against the opposing wall outside the window. As described above, the slats 1 with the press contact portion as the single product can be arranged apart from each other by an arbitrary number, and the purchaser himself can assemble the blind 100 according to his / her taste in a DIY sense. Of course, the number of the slats 1 that are spaced apart from each other in this way has the advantage that the shielding adjustment such as sunlight and the outside can be flexibly performed.

  FIG. 2 is a perspective view of the slat 1 with a press contact portion according to the present invention in which the press contact portion 20 is constituted by, for example, a tension rod 20A. That is, as shown in FIG. 2 (a), a thrust bar is inserted into the penetrating tube portion 11 provided in the long axis direction of the blade portion 10, and elastic caps 21 such as rubber are fitted and attached to both ends. This tension rod is, for example, a commercially available telescopic rod. A slide rod body having a diameter smaller than that of the pipe body is slidably inserted into a long pipe body, and the slide rod body is inserted into the pipe body. When it is rotated in one direction, it is locked in a non-slidable state, and when it is rotated in the opposite direction, the pipe body and the slide bar body can be expanded and contracted to form a well-known tension bar having a slide lock structure. FIG. 2B is a cross-sectional view taken along line AA in FIG. The strut rod 20A in the drawing is configured to be axially rotatable within the through cylinder portion 11 of the blade portion 10, so that the slat 1 with the press contact portion is formed on the opposing wall of the window frame as shown in FIG. When held in pressure contact, each blade 10 can be pivotally supported, and the degree of light shielding can be easily adjusted manually.

  The blade portion 10 may be made of a thin film material such as a general slat material. Further, in order to prevent the blade portion 10 from rotating more than necessary within the through tube portion 11 due to wind from the window, irregularities (not shown) are added to the inside of the through tube portion 11 so that the slat opening / closing angle can be maintained by appropriate rotational friction. It is configured. In this respect, it is different from a configuration in which the curtain simply hangs down from the tension bar like a so-called cafe curtain.

  Further, the short side width of the blade portion 10 is about 25 mm to 50 mm in a slat used for a normal blind. However, in the slat 1 with a pressure contact portion of the present application, the through cylinder portion 11 is cylindrical, and thus particularly in the case of a horizontal blind. In addition, since it is difficult to bend as compared with the conventional blind, it is possible to make the blade portion 10 wider than 200 mm. Another advantage is that various designs can be easily added to the wide blade portion 10. In addition, although the penetration cylinder part 11 is provided in the short side center of the blade | wing part 10 in the figure, it may be biased to either the right or left of a short side in design.

  FIG. 3 shows a slat 1 with a pressure contact portion according to another embodiment. That is, unlike the embodiment of FIG. 2, a short through cylinder 11 is provided only at both ends of the short side, and a tension rod 20A is provided therein. In this configuration, in order to give rigidity to the entire blade portion 10, it is necessary to use a relatively thick material instead of a thin film material.

  Further, in the configuration of FIGS. 2 and 3 described above, a configuration in which the tension rod 20A is rotatably inserted into the through cylinder portion 11 of the blade portion 10 is disclosed, but the slat 1 with a pressure contact portion according to the present application is in this configuration. Not limited to this, as shown in FIG. 4, the screw can be advanced and retracted via a simple screw mechanism 20 </ b> B including a screw shaft 22 and a screw receiver 23, whereby the elastic caps 21 at both ends are advanced to oppose the wall of the window frame. You may comprise the press-contact part 20 made to press-contact to. In this configuration, when the blade portion 10 is rotated, the screw receiver 23 is manually loosened with respect to the screw shaft 22 and the blade portion 10 is rotated by a predetermined angle. 21 is pressed against the opposite side wall of the window frame. In this case, it is preferable to increase the diameter of the screw receiver 23 so as to facilitate manual rotation.

  FIG. 5 is a front view of still another embodiment of the pressure contact portion 20. Here, an embodiment in which the press contact portion 20 is configured with an external structure 20 </ b> C that is independently provided outside the axial center direction of the blade portion 10 is disclosed. In this externally attached structure 20C, the press contact 25 stored in the press contact storage body 24 is urged toward the blade portion 10 by the spring body 26. That is, the presser 25 is pressed against the end face of the blade portion 10 by the spring body 26, and at the same time, the elastic cap 21 is pressed against the opposing wall of the window frame. In this case, since the press contact 25 is rotatable in the press contact storage body 24, the blade portion 10 held in press contact can be pivotally supported by manual operation, and the opening / closing angle can be freely set.

  In addition to the above, various configurations of the pressure contact portion 20 are conceivable. With the pressure contact portion 20 described in the present invention, the elastic cap 21 is pressed against the opposing wall of the window frame at one end and the blade portion 10 is pressed at the other end. In addition, the configuration includes all the related art configurations in which the opening / closing angle of the blade portion 10 can be manually set freely, and is not limited to the above configuration.

  FIG. 6 is a front view when the blade portion 10 of the slat 1 with a press contact portion according to the present invention faces the front, and FIG. 7 is a front view when the blade portion 10 is rotated. These rotation operations are configured such that the individual slats 1 can be manually rotated to rotate the blade portion 10 at an arbitrary opening / closing angle. In addition, as shown in FIG. 6, in order to hold the blade | wing part 10 in a predetermined position, you may provide the protrusion 27 for a latch in the lower part of a tension rod.

  FIG. 8 is a front view showing a blade portion 10 having another shape of the slat 1 with a pressure contact portion according to the present invention. That is, you may comprise the blade | wing part 10 in a different shape for every slat 1 with a press-contact part. Moreover, you may add arbitrary designs for every blade | wing part 10 as shown in FIG.

  As described above, the blind 100 according to the present invention has an advantage of being configured by the required number of slats 1 with the press contact portions at a necessary interval according to the width of the window frame. At this time, if the slats 1 with the pressure contact portions are installed at equal intervals, the slats 1 with the pressure contact portions are connected to each other by the connecting pin 30 between the blade portion 10 and the elastic cap 21 as shown in FIG. Also good. As shown in FIG. 10B, the connecting pin 30 may be composed of a wire having both ends ring-shaped. In the case of this connecting pin, the elastic cap 21 is temporarily removed from the pressure contact portion (such as a tension rod) 20, and after the connecting pin 30 is mounted, the elastic cap 21 is mounted again, and the elastic cap 21 is rotationally pressed against the opposing wall of the window frame. The purchaser himself / herself assembles the blind 100 according to his / her preference. Another shape of the connecting pin 30 may be a shape in which a part of the ring is missing as shown in FIG. In this case, the slats 1 with the press contact portions may be connected so as to be fitted from the side of a tension rod or the like without removing the elastic cap 21.

  The slat 1 with a pressure contact part of the present invention can be manufactured with a material that can be easily cut with scissors, for example. When such a material is used, if the length of the blade portion 10 of the blind 100 according to the present invention is too long than the window frame width, the purchaser himself / herself can cut the blade portion 10 with scissors. The length can be easily adjusted. On the other hand, if it is too short, a slidable extension blade portion 12 can be added to the blade portion 10 in order to extend the length in the major axis direction of the slat 1 with the press contact portion as shown in FIG. . That is, the extended blade portion 12 has a cylindrical and sandwich shape sandwiched from the front and back of the end portion of the blade portion 10 and is configured to be advanced and retracted in the long axis direction of the through tube portion 11. The extension blade portion 12 is held by the blade portion 10 so as to be completely overlapped with the end portion of the blade portion 10 when retreating, and is manually slid in the direction of the arrow while being held by the blade portion 10 when advanced. Unlike the blade portion 10, the extended blade portion 12 does not have the penetrating cylinder portion 11 and has a simple cylindrical and sandwich shape, so that the extended blade portion 12 can slide in the long axis direction while covering the blade portion 10. Therefore, the slat 1 with the pressure contact portion according to the present invention slides the extension blade portion 12 from the end portion of the blade portion 10 by the required length when the extending rod 20A is advanced according to the width between the opposing walls of the window frame. By adjusting the length, it is possible to easily adjust the length. For this reason, in the blind 100 in which a plurality of slats 1 with press contact portions are arranged at predetermined intervals, for example, in the case of the vertical blind shown in FIG. 1, the horizontal width is the number of slats 1 with press contact portions and the vertical width is an extended blade portion. 12, each can be adjusted flexibly to adapt to the size of the window frame. In this respect, the conventional blind whose size is determined at the time of factory shipment has an advantage that the field adaptability is remarkably improved.

  As described above, the required number of slats 1 with pressure contact portions of the present invention are purchased, and then the purchaser can assemble the blind 100 according to his / her window frame size according to his / her preference. Has marketability.
