DETAILED DESCRIPTION OF THE INVENTION
A frame adjustment fitting according to a first embodiment of the present invention will be described with reference to FIGS.
The frame body adjustment fitting 1 is provided between a frame body 2 for attaching a door, a window and the like and a housing 3 (see FIG. 2) in which the frame body 2 is disposed. And the expansion member 5 is comprised. Among these members, the wedge member 4 is composed of a truncated cone-shaped head portion 4a having a predetermined taper angle and an elongated leg portion 4b that is threaded. On the other hand, the expanding member 5 has a substantially rectangular parallelepiped shape, and a tapered hole 5a that engages with the head 4a of the wedge member 4 and a small hole 5b that is continuous with the tapered hole 5a are formed at the center thereof. Further, the taper hole 5a is provided with a slit 5c having a longitudinal groove in FIG. 1 that passes through the central axis of the taper hole 5a. Further, the widened member 5 is provided with bottomed large holes 5d in which springs 6 are arranged at substantially equidistant positions across the tapered hole 5a, and further, both outer sides parallel to the slit 5c. On the side surfaces, V-grooves 5e are provided in the vertical direction at a predetermined pitch from the substantially central portion to the rear end portion in FIG.
[0009]
By the way, in this embodiment, the expanding member 5 of the frame adjusting metal fitting 1 is provided with a recess having an appropriate shape in the frame 2 as shown in FIG. 1, and inside the case body 7 fitted in the recess. It is arranged. That is, the case body 7 includes a thin-walled cylindrical member 7a having a rectangular cross section and a flange member 7b that is provided at one end opening of the member 7a and extends along both long sides thereof, and the flange member 7b. Are inserted into the recesses of the frame 2 by screws 8 arranged in the insertion holes. The expanding member 5 is disposed in the member 7a of the case body 7 and has one end seated on the frame body 2 and the other end seated in the large hole 5d of the expanding member 5. 6 urges the frame 2 away from each other.
By the way, the case body 7 may be fitted into the recess of the frame body 2 by a press-fitting method. Reference numeral 7c denotes a stopper for preventing the expansion member 5 from coming off.
[0010]
Such an expanding member 5 is expanded by the wedge member 4 inserted from the through hole 2a of the frame body 2 because the tapered hole 5a engaged with the head portion 4a is expanded, while the fixing means 5 is fixed. By the wedge member 4 also serving as a part, the leg portion 4b is inserted through the small hole 5b and screwed into the screw hole of the housing 3 and fixed in a state of contact with the housing 3 (see FIG. 2). ).
