JPS5840226Y2 - Movable adjustment device for blind wings in a grid - Google Patents

Description

[Detailed description of the invention] This invention is based on the invention in which the blinding wing pieces in the screen lattice installed on the front side of the exterior window of a house can be rotated independently to open and close. This invention relates to a movable adjustment device.

In the past, various types of grids have been seen in which several blinding wings are rotatably mounted, but in these cases, all of the blinding wings are movable in conjunction with each other at the same time. Although it is convenient to rotate the whole thing at the same time, it has the disadvantage that it is not possible to adjust the most effective blinding angle, opening and closing of ventilation and lighting, etc. for each blindfold board depending on the surrounding location where it is installed. It has the disadvantages that failure easily occurs and the structure is complicated.

Therefore, this invention is an improvement on this conventional drawback, and its structure is such that the blind blades attached to the fixed frame of the grid are fitted with blade shafts protruding from both ends. A movable uneven surface is formed on the outer periphery of the tip of the fixed shaft, and a bearing made of an elastic body or the like into which this movable uneven surface is fitted has an internal uneven surface that is rotatable with the movable uneven surface. , this bearing is fitted into a fitting hole provided in one of the fixed frames of the vertical and horizontal frames.

Therefore, it is very convenient to be able to individually move the opening/closing angle to the optimum opening/closing angle that is most needed for blindfolding, ventilation, lighting, etc.

Moreover, the movable operation of the blind wing pieces is easy, and once fixed in a predetermined position, accidental movement due to strong winds or the like can be reliably prevented.

Next, one embodiment of this invention will be explained with reference to the drawings.The surface lattice 14, which is attached to the front of the exterior window of a general house using the mounting legs 15, has fixed frames 6, 6 of the upper and lower frames or the left and right vertical frames. Several blind wing pieces 1, 1, . . . are installed on the bridge.

The blind wing pieces 1, 1 each have a hollow metal wing shaft 10 formed at the center in the longitudinal direction, and the wing shaft 10 has retaining portions 16, 16 formed at both longitudinal ends thereof, and Transparent or semi-transparent divided wings made of synthetic resin are fitted into the engaging portions 16, 16.

Next, the blade shafts 2, 2 are fitted onto both ends of the blade shaft 10, and a portion of the blade shafts 2, 2 is provided to protrude.

Movable uneven surfaces 3, 3 that are uneven in the axial direction are formed on the outer periphery of the protruding portions of the blade shafts 2, 2.

Next, a bearing 4 having a rectangular cross section that fits into the movable uneven surfaces 3, 3 from the outside is made of various elastic materials, and is rotatably fitted into the movable uneven surfaces 3, 3. Inner surface uneven surfaces 5, 5 are formed with unevenness.

Next, a fixing frame 6 for fixing the bearing 4 is composed of an inner main frame 7 and an outer sub-frame 8, and has a fitting hole 9 into which the bearing 4 is fitted.

Further, the main frame 7 and the sub frame 8 are provided with opposing protrusions 11 and 12 protruding from which the bearing 4 engages.

Reference numeral 13 indicates a screw that unites the main frame 7 and the sub-frame 8 into one body.

This device has the above-mentioned configuration, and in order to use it, if any number of blind blades 1 in the grid are tilted or moved one by one to the required angle, as required, When the blade 1 is rotated by holding both ends, the blade shaft 2 fitted to the blade shaft 10 is also rotated at the same time, and the movable uneven surface 3 is rotated by the bearing 4.
If the blades 1 are pressed one by one to a predetermined inclination angle or to a closed position, the blades 1 can be fixed and used by fitting the uneven surfaces.

According to this invention as described above, the advantage is that only the blinding wing pieces attached to the surface grid can be individually movably adjusted to any desired angle, taking into consideration the effects according to the conditions such as blinding, ventilation, and lighting. It has a practical effect.

Since the movable uneven surface of the blade shaft provided at both ends of the blade and the inner uneven surface provided inside the bearing are rotatably fitted loosely, the unevenness of both blades is adjusted after the movement of the blade is adjusted. By fitting the surfaces, movement due to strong winds or vibrations can be prevented, and it is also possible to make slight rotations to move the uneven surfaces of both in small increments.It is very convenient because many inclination angles can be selected, and it is also possible to use the conventional interlocking mechanism. Since the structure is omitted, the structure is simple, there are few failures, etc., and it can be manufactured at low cost.

Furthermore, if the blind wing pieces of this invention are made of transparent synthetic resin except for the wing shaft, the interior will not be darkened, and if colored, a beautiful decorative effect can be obtained, and the whole will be lightweight, making it difficult to install and transport. It has a convenient effect.
