JP3172939U - Simple blind - Google Patents

Abstract

An object of the present invention is to maintain the original shape even when some wind passes when a window or door is opened, and to block the line of sight in a specific direction and to ensure ventilation.
SOLUTION: The position and inclination are fixed with a shaft string in which a slat whose inclination is changed by wind force is stretched like a string and a frame with a slit, and a certain amount of weight is obtained as a whole while being a lightweight and simple part. As a result, a blind that opens and closes in the horizontal direction like a curtain instead of rolling up is provided, ensuring air ventilation while blocking the line of sight in a specific direction without changing the air volume.

Description

  The present invention relates to a simple blind in which a gaze shielding direction is limited by a fixed slat that emphasizes ventilation.

  There are curtains, blinds, etc. as tools for avoiding gaze. If the curtain is unfolded and closed, the line of sight is blocked, and if the curtain is pulled and opened together, the field of view of the entire opening can be secured. The blind can operate the elevating cord to lower the slat, and if the tilt of the slat is operated with the elevating cord or the operation stick, the line of sight is blocked, and if the slat is raised by operating the elevating cord, the entire open field can be secured.

  However, if the wind blows even if the curtain is closed with the window open, the wind will blow even if the blind is closed with the window open. If it is a little strong, the whole blind may be drowned, and even if it is excellent in the operation of the field of view, it is inconvenient in terms of ventilation.

  There are measures to install blinds outside fixed slats in bathroom windows to block the line of sight and ensure ventilation, and blind shutters, etc., but they are fixed to the windows, heavy in weight, and insufficient lighting. There is.

  The problem to be solved is to block the line of sight with an open window and at the same time realize ventilation and daylighting.

  The main feature of the present invention is that the vertical frame is inserted into a frame made of a lightweight material comb and a slat is fitted to form a blind, which is used on a new or existing curtain rail.

  The blinds of the present invention block the line of sight by hanging on the curtain rail and can open and close like a curtain even if it can not be shrunk, making it easy to enter and exit the opening, and the slat angle is fixed for stable ventilation There is an advantage of getting.

FIG. 1 is a side perspective view showing the entire simple blind. Example 1 FIG. 2 is a top view of the simple blind. Example 1 FIG. 3 is a front view of the simple blind. Example 1 FIG. 4 is a side view of the simple blind. Example 1 FIG. 5 is a view taken along the shaft of the simple blind. Example 1 FIG. 6 is a front view of main components of the simple blind. Example 1 FIG. 7 is a route diagram of the shaft of the simple blind. Example 1

  The function of winding up was abolished, and a blind type shielding device was formed only by a slat made of a lightweight material, a shaft string penetrating the slat, a comb supporting both ends of the slat, and a frame supporting the tension of the comb and the shaft string.

  FIG. 1 is a side perspective view of a production example including all the parts necessary for explaining the present invention and arranging an appropriate number of slats to image a blind, and FIG. 2 is a top view of the same production example. FIG. 3 is a front view of the same preparation example, FIG. 4 is a side view of the same preparation example, and FIG. FIG. 6 is a front view in the case where main parts are arranged in a plane, and FIG. 7 is a view of only a frame and a shaft string for explaining an attachment path of a shaft string which is one part supporting a slat. is there.

  The frame is made of a strong lightweight material, and the frames are fixed with wood screws or screws in consideration of disassembly and storage. The material of the slats is a translucent or opaque thin and light plastic, wood, or chamfered lightweight metal, and the shape is a rectangle with rounded corners in consideration of safety and the relationship with the curtain to be used together. Comb molds are made using a sheet of styrofoam plate, plastic plate, or chamfered lightweight metal plate with fine grains and high density, and the slits need to be wider than the thickness of the slats. Fix with wood screws, screws, scissors, or adhesive. The shaft strap is made of water-resistant and durable material, and the through-holes in the horizontal frame, middle frame, and slat are the same as or slightly smaller than the normal diameter of the string, and larger than the diameter at the time of contraction. For each wedge that holds the end of the string, use a wood screw or a screw that is slightly smaller in diameter than the string through-hole formed in the horizontal frame. The blindfold is made of the same material as that defined mainly by the frame or slat. Use a metal made of metal that can be passed through the ring of the curtain rail.

  As shown in FIG. 5, a pair of combs sandwiching one vertical frame can tilt the slats by shifting each other vertically and fixing it to the frame. The length b shown in FIG. 6 is set so that the end of the slat is slightly outside the range of the length a when the slat is tilted and inserted into the comb-shaped slit.

  Each shaft strap has a knot at one end, the tip of the opposite end is squeezed and hardened with glue, etc. to make it easy to pass through the hole, and then put out from the inside of the hole on the horizontal axis, and the other end Put it in the hole from the outside, pass it through the slat and then through the hole in the inner frame. At this time, half the number of slats can be fixed by pulling the string with a strong force to make the inner frame go around. Further, through the remaining holes of the slats, put them in from the inside of the hole in the other side frame, put them in from the outside of the other hole, pull them out with force and fasten with a wedge. The path of the hole in each string frame is as shown in FIG.

  The horizontal length of the frame is equal to or less than the horizontal length of the window or door to be attached, and the vertical length of the frame is equal to or less than the height of the curtain rail mounting position. The number of slats, the necessity of the middle frame, and the length of each shaft strap are adjusted according to the length of the vertical frame. The total number of comb slits is the same as the number of slats. The vertical length c of one comb shape in FIG. 6 is proportional to the number of slats. There may be a cutting part in the middle of the vertical length c of one comb type. To put it to the extreme, create a comb type with the length of d for the number of slats and combine them on the vertical frame. One comb may be formed. By this method, it is possible to arrange slats having different inclinations simultaneously in one blind. The length of the short side of the blindfold is adjusted by the difference between the total length covered by the short side of each slat and the inner length of the frame.

  The present invention has neither the back nor the front. If the position of the heaton is changed, there is no vertical or horizontal, and the user can install it on the window or door at any angle according to the direction of the line of sight to be blocked. It is assumed that it is attached to a curtain rail and used together with a conventional curtain, like a lace curtain intended for ventilation and lighting.

  It can be attached to a window or door curtain rail to block the line of sight in a specific direction and prevent airflow while limiting the freedom of access.
