JPS603799Y2 - T-shaped razor - Google Patents

Description

[Detailed description of the invention] The present invention has grooves 4°4 cut out on both sides of the lower plate part 2 of the holder 1, which is separated from the upper plate part 12 and the lower plate part 2. At the upper outer end of the elastic intervening piece 5 between the grooves 4, 4, an engaging protrusion 6 with a circular surface and a top protruding toward the rear is formed on both sides of the head 8 to which the blade 7 is fixed. A T-shaped razor, in which an engagement recess 10 having a semicircular cross section that engages with the engagement protrusion 6 is formed on the lower surface of the holder 9, and the head 8 is inserted into the holder 1 from the front and is detachably attached. Accordingly, an object of the present invention is to provide a T-shaped razor whose head, which has a solid blade body, can be accurately and easily mounted on a holder to reliably prevent unintentional movement.

In the figure, 11 is a handle integrated with the U-shaped holder 1;
13 is an intervening spacer between the upper and lower two-blade blade bodies 7, 1;
4 is a hole for removing shavings, etc.;

When the head is inserted into the holder, both side edges of the upper plate part 12 abut and lock inside the left and right locking steps 15 on the upper part of the head to ensure proper installation.

The head, holder, etc. shall be made of plastic.

The engaging protrusion 6 has a circularly curved surface and a top protruding toward the rear.

The engagement recess 10 is formed to have a semicircular cross section.

Further, as shown in FIG. 4, the split groove 4 is cut out in a U shape at the front and back of both side edges 3 of the lower plate portion 2, and the elastic intervening piece 5 is interposed in a rectangular shape between the front and back split grooves 4, 4. It is formed.

Since the present invention has the above-described structure, when it is installed, the head 8 with the blade 7 clamped and fixed is inserted into the holder 1 from the front, and the elastic intervening piece 5 is elastically raised and lowered by the pushing action of the head. By elastically engaging the engagement protrusion 6 into the engagement recess 10, the engagement protrusion 6 acts to press the head 8 upward and backward, thereby pushing the head 8 into the engagement recess 10. While using the head 8 for shaving,
It has the effect of being able to be held securely in the holder to prevent accidental movement or detachment, and to be able to insert and install it accurately and easily.

In addition, when removing the head 8, push the head 8 forward with your fingertips, and the elastic intervening piece 5 elastically descends to disengage the engagement protrusion 6 from the engagement recess 10, thereby making the head freely engageable and detachable from the holder. have

Therefore, compared to the conventional structure that engages only in the center, the present invention can be installed more reliably and safely without shaking from side to side, and compared to the conventional structure that engages at the front, rear, left, and right points. It is simple and easy to install without the need for confirmation, and has features that the engagement and installation are more appropriate and purposeful than those mentioned above.
