Description

[Detailed explanation of the idea] This invention relates to a crescent for Satsushi.

More specifically, the present invention relates to a sash crescent that includes a washer having an elongated hole that is rotatably and irremovably fixed to the base of the crescent.

A typical crescent for a sash has a pair of mounting holes in its base, and a mounting screw is screwed into the sash through the holes to fix the crescent to the sash.

However, the mounting holes of the crescent, that is, the screw holes of the sash that match the mounting holes, have different pitches depending on the manufacturer of the crescent, its type, and the year of manufacture.

For this reason, when installing a new crescent due to a crescent failure, if the holes of the new resent and the screw holder of the existing sash do not match, it is necessary to drill a hole for another screw holder on the sash, and that work is necessary. It's making it annoying.

This idea was proposed with the aim of solving the above-mentioned problems with the conventional sash crescent, and the pedestal of the crescent is provided with a pair of holes with a diameter larger than the mounting screw.
It is an object of the present invention to provide a crescent for a sash, characterized in that a washer having a long hole through which a threaded portion of a mounting screw is inserted is rotatably fixed.

An embodiment of this invention will be described with reference to the accompanying drawings.

A pair of holes 3 are bored in the base 2 of the crescent 1 for sash.

This hole 3 is larger than the diameter of the mounting screw and has a size that allows the existing pair of screw receivers drilled in the sash to be positioned inside this hole 3.

A washer fitting groove 4 is provided in the upper part of this hole 3.

This groove 4 has a size that rotatably accommodates a washer 5, which will be described later, and has a depth such that the washer 5 and the upper surface of the pedestal 2 are flush with each other.

The washer 5 has a long hole 6 through which the threaded portion of the mounting screw is inserted.

The washer 5 has a step 7 which is connected to the hole 3 of the base 2.
It is seated on a stepped portion 8 formed between and the fitting groove 4.

A cylindrical leg 9 extending downwardly from the step 8 has a length such that it is inserted into the hole 3 of the pedestal 2 in a loose relationship and extends some distance below the hole 3.

In the example described above, the washer 5 is placed in the fitting groove 4 of the base 2.
so that the stepped portion 7 of is seated on the stepped portion 8 of the pedestal, and the tips of the leg portions 9 of the washer 5 extend below the hole 3 of the pedestal 2,
Insert washer 5.

In this state, the washer 5 is in a rotatable relationship with the base 2.

Next, the tip of the leg 9 of the washer 5 is attached to the washer 5.
The washer 5 is caulked to the pedestal 2 to ensure a rotational relationship with respect to the pedestal 2 and to prevent the washer 5 from separating from the pedestal 2.

This caulking work may be performed around the entire circumference of the leg portion 9 or at a plurality of appropriate locations.

Furthermore, a notch may be made at a suitable location on the leg portion 9 to raise it up.

Separately from the above-mentioned example, as shown in FIG. It may be caulked to the pedestal 2 so as to be rotatable relative to the pedestal 2.

Alternatively, as shown in FIG. 6, a thread may be cut at the tip of the leg 9 of the washer 5, and a thin nut 10 may be tightened thereto to ensure a rotational relationship between the two and to prevent them from separating.

Furthermore, as shown in FIG. 7, a flat washer 5 having an elongated hole 6 is rotatably inserted into the groove 4 of the base 2, and a self-tensioning ring 11 or a spring is used to remove the washer 5 from the base 2. It may also be possible to prevent the separation of

Note that the long holes may be linear or cross-shaped.

To attach the crescent 1 equipped with the washer 5 of the above-described example to a sash, insert the washer 5 so that the center of the hole in the screw receiver bored in the sash coincides with the longitudinal center of the elongated hole 6 of the washer 5. Rotate until they match, then screw the screw into the sash to secure them both.

As is clear from the above, in this invention, the screw receiver in which the long hole of the washer is drilled in the sash can be rotated so that it can match the groove, so the crescent of this invention can be used for all sashes. Become.

Furthermore, since the washer is held on the base of the crescent, parts management is easy without the washer being lost during transportation or storage.
