Description

  The present invention relates to an auxiliary tool for easily opening and closing a manual shutter such as a garage.

  While manual shutters such as garages can be opened and closed easily, when they become a little old, the springs inside are deformed, the sliding between the shutter and the guide worsens, it becomes astringent due to various reasons such as rusting, and opening and closing becomes difficult.

  Normally, there are two handles for lifting the shutter at a height of about 60 cm. However, the dent to put in the hand is only the thickness of the shutter, and it was too shallow to apply enough force.

  When you first open the shutter, you have to start with a special effort. However, when the shutter gets awkward, the hand slips and hurts your nails.

  Also, after lifting a little, if the shutter movement was still awkward, it was often lifted by turning the hand to the bottom plate of the shutter, but the bottom plate was dirty because it was on the ground, and the hands became dirty.

  When closing the shutter, the bent part of the hook is hooked and lowered into the hole in the center of the bottom plate of the shutter that is raised, but the hole is usually small, especially when it is dark and difficult to hook well was there.

  Also, when pulling down the shutter, the hook had to be removed from the shutter when the shutter was lowered to some extent.

  Attached to an existing manual shutter, it provides an auxiliary tool that can easily open and close the awkward shutter and does not hurt or get dirty.

  The present invention has been made in view of the above problems, and is an auxiliary tool attached to the bottom plate of the shutter. The T-shaped handle is at a height of about 35 cm above the ground. Upright, the metal shutter lifting plate attached to the lower part of the lion wraps under the bottom plate of the shutter, and is connected to the mounting plate attached to the inner bottom plate of the shutter via a spring hinge .

  Reiko is pressed against the shutter by the force of the spring. Choshi is bent about 30 degrees outward at the top, and the handle is away from the shutter. Both ends of the handle have rollers attached to the ends.

  To lift the shutter, first grab the handle, pull the lion devotional forward, the corner of the shutter lifting plate attached to it will be the fulcrum, the tip of the shutter lifting plate will be lifted, and the shutter will be pushed up slightly It becomes an opportunity to wind up the shutter. Then lift the handle up and the shutter will go up easily.

  At that time, the hand may be released from the opening / closing assisting tool, and the assisting tool is pressed against the shutter by the force of the spring. When the shutter rises further and the handle of the assisting tool hits the eaves, the upper part of the assisting lever is bent outward, and the end of the lever at both ends of the handle is smoothly pushed outward. When the shutter is rolled up to the top, Choshi is almost level under the eaves and stops.

  When closing the shutter, it is not necessary to hook the hook into the hole. If the position of the handle is too high to reach, you can attach a string that is long enough to reach the handle.

  As described above, using the assisting tool of the present invention, the manual shutter, which has become a little old and awkward, can be opened and closed easily by gripping only the handle, so that the hand is not soiled or damaged.

  The upper part of the shutter opening / closing aid with a total height of about 35 cm is a cocoon-dedicated instrument with a length of about 30 cm, and a handle with a length of about 15 cm is attached to the upper end of the T-shaped, A freely rotating roller that is slightly thicker than the diameter is attached. Assuming that the lion sacrifice is perpendicular to the ground, the lion gift is bent outward about 30 degrees at about 2/3 of the height.

  At the bottom of Choshi dedication, there is a shutter lifting plate with a slightly widened fan. At the lower end of Zushi dedication, the pulling plate is bent about 45 degrees outward, and then gently draws a circular arc from there and about 5cm downward. When lowered, make it almost perpendicular to the ground. Therefore, the pulling plate is bent by 90 degrees further inward and is horizontal. The length of the horizontal part is about 3 cm.

  The tip of the horizontal portion of the pulling plate is cut out leaving a left and right elongated portion, and the elongated portion is rounded to wind the rotating shaft. The rotating shaft is shared, and a mounting plate to the shutter is mounted on the opposite side of the lifting plate by winding the rotating shaft in the same manner as the lifting plate. Therefore, the lifting plate and the mounting plate can be freely rotated just like a hinge.

  The front end of the mounting plate is bent upward by 180 degrees in a U shape so as to embrace the shutter bottom plate, and a bolt hole for fixing to the bottom plate of the shutter is cut at the top. Double bolts are screwed into the bolt holes. A spring is attached to the center of the rotating shaft. When the auxiliary tool is attached by tightening the bolt of the mounting plate to the bottom plate of the shutter, the lever is pressed against the shutter by the force of the spring.

  An embodiment of the shutter opening / closing assisting device of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing the whole, and is a standing view seen from the back side of the shutter when attached to the shutter. The shutter is not shown to avoid complexity. The overall height is 38 cm, the length of the handle 1 is 14 cm, the insulator 2 is 30 cm long, and it is bent about 30 degrees outward at a bending point 3 at a height of about 2/3 of the whole. Zushi dedicated, the handle is made of steel pipe with a diameter of 1.5cm.

  Choshi is connected to the shutter lifting plate 4 at the bottom. FIG. 2 shows a partial side view in a free state where the auxiliary tool is not attached to the shutter. The shutter lifting plate 4 is a strong steel plate having a thickness of 3 mm, and the portion 4-1 is a shutter of each manufacturer. Large and gently bent to fit, and the bottom of 4-2 is flat to contact the bottom plate of the shutter. The bottom is 3 cm long and 9 cm wide.

  Inside the shutter, a bottom plate fixing bracket 5 made of a similar steel plate is fixed to the shutter inner bottom plate with fixing bolts and nuts 6, but the bottom plate fixing bracket 5 is connected to the shutter lifting plate 4. A portion 7 where a part of the plate is left to be cut long and a portion 8 where a part of the end of the shutter lifting plate 4 is left to be cut are rounded, and both are wound around a rotating shaft 9 made of a steel round bar having a diameter of 5 mm to form a hinge. is doing.

  In addition, a spring 10 is attached to the central portion of the rotary shaft 9, and the shutter pulling plate 4 and the insulator 2 connected to the shutter are attracted to the shutter side by the force of the spring so that the insulator 2 is brought upright. Further, end rollers 11 are attached to both ends of the handle.

  As shown in FIG. 3, a magnet mounting base 12 is attached around the bending point 3 of the insulator 2 and a magnet 13 is fitted therein, and other specifications are the same as in the first embodiment.

  Folding element 2 that is attached to the shutter is pressed against the shutter by the spring 10, but if there is a slight gap, there may be a rattling sound when the wind blows. The magnet 13 is effective for improving the adhesion between the shutter and the lever.

  As described above, by using the shutter opening / closing assisting device of the present invention, it is possible to easily open and close a normal manual shutter as well as a troublesome manual shutter opening and closing, and the convenience of the shutter is remarkably improved. In addition, since the position of the handle is higher than the ground, it is hard to get dirty and it is not necessary to get your hands dirty.
