Description

[Detailed Description of the Invention] The present invention relates to a frame correction tool for correcting the distortion of a frame consisting of four sides, such as a sunshade, so that it has an accurate shape.

= Sashes that are generally attached to windows in buildings are quadrilateral, consisting of left and right frames and upper and lower horizontal frames. It is fitted and fixed into an opening in a building surrounded by

However, in such cases, the satsushi itself may not be a perfect square, that is, the squares are not perfectly right angles, and may be in a distorted state. This has to be corrected one by one, but it is extremely difficult to do so when the ends of the jamb and horizontal frame are fixed together in a rigid knot shape.
This has the disadvantage of requiring a great deal of effort and time.

The present invention was made in view of the above points, and the purpose is to provide a new correction tool that can relatively easily correct the distortion of the frame of the satshu, etc. In some cases, it was put into practical use by focusing on the fact that the lengths of the diagonals are the same.

The structure of the present invention will be explained based on the drawings showing one embodiment. In FIG. 1, 1 is a rod-shaped screw rod, and the front and rear of the screw rod 1 have inclinations opposite to each other on the left and right sides. Two types of male screw portions 2, 3 are formed, and cylindrical moving tools 4, 5 are screwed into these male screw portions 2.3, respectively.

The proximal end of the screw rod 1 is a handle 6 bent into a horn shape, and the moving tool 5 on the side of the handle 6 is formed into a slightly elongated shape and is provided with a grip portion 7.

8゜9.10.11 are four continuous rods, the base ends of which are pivotally attached to each moving tool 4, 5, two on both the left and right sides,
Its tip is connected to a continuous hit 8, which is pivotally connected to the opponent moving tools 4 and 5.
9, 10, and 11, respectively, to form a quadrilateral link.

In the middle of these four connecting rods a, s, io, and ii, the base ends of tensioning tools 12, 13, 14, and 15 made of piano wire or the like are pivotally supported on the base end side of the central part. Concatenated.

16, 17, 18, 19 are these tensioning tools 12, 13
, 14, 15, and is made by bending both ends of a board punched out at right angles and locking them to the squares of the frame.

In the above configuration, when the screw rod 1 is rotated by holding the grip portion 1 and the handle 6, the two moving tools 4 and 5 screwed to the screw rod 1 move in opposite directions, that is, in the direction of approaching and separating. 4
Transform the link consisting of book links 8, 9, 10.11.

In this case, the locking tools 16, 17, 18 facing each other in the diagonal direction
, 19, for example, the length between the locking tool 19 and the locking tool 17, since the lengths of the tensioning tools 15 and 13 are constant, It is determined by the length t between both moving tools 4,
The maximum value is when 5 are spaced apart the most.

Therefore, to explain how to use this correction tool based on the schematic diagrams in FIGS. 2 and 3, first, the length between the opposing locking tools 16, 18, 17° 19 is determined as described above. Two opposing locking tools 16.
18 is locked.

At this time, the other locking tools 17 and 19 are either lightly locked to the other corner to allow the tensioning tools 13 and 15 to flex, or are left free without being locked.

After that, when the handle 6 is held and the screw rod 1 is rotated to move the moving tools 4 and 5 closer together, the locking tools 16 and 18 are pulled toward each other, and accordingly, the locking tools 16 and 18 are pulled toward each other. As a result, the distortion of the satush 20 is gradually corrected.

Then, as shown in Figure 3, all the locking tools 'f6, 17°i
a, is is locked on the corner, and the four tensioning tools 12.1
When all 3, 14, and 15 are tense, it is in a perfect rectangular state, and after fitting it into the opening of the building in this state, the correction tool is removed.

Fig. 4 shows the case where the orthodontic device of the present invention is used in a trapezoidal frame 20, and Fig. 5 shows the case in which the orthodontic tool of the present invention is used in a case where each side of the frame 20 is bulged outward in an arc shape. In this way, with the correction tool of the present invention, it is possible to reliably correct corners of various shapes other than right angles.
Furthermore, it is possible to proceed with the one shown in FIG. 5 and use it for a completely circular one.

Furthermore, in the present invention, since a wire material such as piano wire, which is light and has a large degree of freedom, is used as the tensioning tool, the correction tool of the present invention is easy to handle and convenient to carry without being bulky.

Moreover, since both moving devices are connected by a quadrilateral link,
When using the corrective device of the present invention, the two moving devices described above do not make any relative movement, especially rotational movement, except for movement in the axial direction.

Therefore, the rotational moment applied to the screw rod is not transmitted to the frame, and the frame is not twisted, which is a remarkable effect.

In addition, a handle for rotating the screw rod is provided at the base end of the screw rod, and the moving tool on the handle side is formed into a long length and a grip portion is provided, so that the screw rod can be easily rotated. It is something that
