The fastener bracket adjustment bracket according to the present invention is such that the adjustment screw is screwed into the screw hole of the connecting plate portion of the hook plate through the screw receiving hole of the screw support plate portion of the base plate. The hook plate is moved forward and backward with respect to the fastener metal fitting by rotating the adjusting screw in an appropriate direction using a driver groove in the head abutted against the side surface of the screw support plate portion far from the metal fitting. A simple adjustment mechanism is provided, so that even if there is an error or a deviation in the position of the attachment between the fastener metal fitting and the receiving metal fitting, it can be easily and accurately corrected to the normal position.
In addition, even if the cross-section shrinkage occurs due to secular change in the packing or seal member attached to the tightening target, the attachment position between the fastener bracket and the receiving bracket is moved to the original position by the simple adjustment mechanism. The required tightening force can be maintained or recovered easily and accurately.

In the illustrated embodiment, the base plate 1 of the adjustment bracket R is fixed to the front side of one tightening object A by a fixing tool such as a screw passing through two upper and lower fixing holes 2. A pair of upper and lower guide claw plate portions 3 and 3 are cut and raised in an L shape on the front side of the right end portion of the base plate 1. The hook plate 4 attached to the front surface of the main portion of the base plate 1 and fitted into the guide claw plate portions 3 and 3 is linearly slidably guided in the left-right direction.

On the front side of the left end portion of the base plate 1, a screw support plate portion 5 is bent at a right angle to the main portion of the base plate 1, and penetrates in the left-right direction at the center portion of the screw support plate portion 5. Screw receiving holes 6 are formed. The hook portion 7 formed at the tip portion that is the right end portion of the hook plate 4 is bent obliquely rearward within a range not exceeding the back surface extension line of the main portion of the base plate 1.

A connecting plate portion 8 that is perpendicular to the main body portion of the hook plate 4 is bent at the front side at the base end portion that is the left end portion of the hook plate 4. A screw hole 9 is formed in the connecting plate portion 8 so as to penetrate in the left-right direction. The tip of the adjustment screw 10 inserted through the screw receiving hole 6 of the screw support plate portion 5 and screwed into the screw hole 9 of the connecting plate portion 8 enters and leaves the hook portion 7 of the hook arm of the fastener metal fitting F. It is in a position that does not interfere with

The substrate 11 of the fastener metal fitting F is fixed to the front side of the other fastening object B by a fixing tool such as a screw passing through the two fixing holes 12 on the left and right. A base end portion of an operation lever 14 is connected by a first pivot 15 to a bearing plate portion 13 raised and formed at the left end portion of the substrate 11. A base end portion of a latch arm 17 is connected to an intermediate portion of the operation lever 14 by a second pivot 16. The main body portion of the operation lever 14 has a U-shaped cross section, and wraps most of the substrate 11 from the front side.

The latch arm 17 includes a left arm plate member 18 and a right arm plate member 19 that are substantially in contact with each other at a certain length portion, and a compression coil spring 20 that is fitted to the left arm plate member 18 and the right arm plate member 19 in the corresponding contact portion. The compression coil spring 20 is compressed between a spring receiving projection 21 at the right end of the left arm plate member 18 and a spring receiving projection 22 at the left end portion of the right arm plate member 19. The latch arm 17 is attached to the outside of the operation lever 14 in a pair of upper and lower sides. Between the left arm plate members 13 of the upper and lower latch arms 17, a rod-shaped tip latch portion 23 is fixed.

In the tightened locking state in which the front end latch portion 23 of the latch arm 17 of the fastener metal fitting F is engaged with the hook portion 7 of the hook plate 4 of the adjustment metal fitting R, the second pivot 16 connects the front end latch portion 23 and the first pivot 15. Since the first pivot 15 and the second pivot 16 are arranged so as to be closer to the substrate 11 than the reference straight line L passing therethrough, the elastic force of the compression coil spring 20 causes the operating lever 14 to rotate clockwise around the first pivot 15. The operation lever 14 is pressed against the front surface of the object B to be tightened, and the tightening and locking state is firmly held.

In order to release this tightening lock, the operating lever 14 is rotated counterclockwise about the first pivot 15. When the second pivot 16 exceeds the reference straight line L during the rotation, the direction of action of the elastic force of the compression coil spring 20 is reversed, and the operating lever 14 is flipped up around the first pivot 15. As a result, the latch arm 17 can move in the direction of the adjustment fitting R, and the leading latch portion 23 is removed from the hook portion 7 of the hook plate 4.

When a required tightening force cannot be obtained because there are errors or deviations in the attachment positions of the fasteners F and the adjustment brackets R, the hook plate 4 is received from the screw receiving hole 6 of the screw support plate portion 5 of the base plate 1. By rotating the adjusting screw 10 screwed into the screw hole 9 of the connecting plate portion 8 in an appropriate direction, the hook plate 4 can be advanced and retracted with respect to the fastener fitting F, and the required tightening force can be secured easily and accurately. Can be adjusted.

When the packing or seal member 24 mounted between the two fastening objects A and B undergoes cross-sectional shrinkage due to aging, the hook plate 4 is fastened to the fastener F by similarly turning the adjusting screw 10 in an appropriate direction. On the other hand, the position of the hook portion 7 of the hook plate 4 is adjusted to the optimum position, and the required tightening force can be recovered and maintained easily and accurately.
A retaining washer 25 is fitted in the annular groove 26 at the neck of the adjusting screw 10.
