Description

[Detailed Description of the Invention] Technical Field This invention relates to a two-blade razor with a dregs removal plate.

BACKGROUND OF THE INVENTION Conventionally, a two-blade razor with a dregs removal plate as shown in FIG. 4 has been considered.

This razor has a lower blade body 5 and an upper blade body 7 via a spacer 6, and the blade holder is fixed between the stand 1 and the top plate 8. A cutout groove 2 is cut out in the rear end of the waist top plate 8. In addition to forming the tensioned portion 3, a removal plate 9 is interposed between the upper and lower blade bodies 7 and 5 so that the spacer 6 is loosely fitted into the loose fitting hole 10 of the removal plate 9.
A circular protrusion 15 is provided to protrude downward from the lower center of the displacement plate 9, and a circular hole 16 into which the circular protrusion 15 is inserted is formed at the center of the rear end of the exclusion plate 9.

In the razor configured in this way, since the circular protrusion 15 of the top plate 8 and the circular hole 16 of the exclusion plate 9 are connected only at one point, the forward and backward movement direction of the exclusion plate 9 is limited. There was a defect that the removal plate 9 was unstable and tilted with respect to the front edges of the upper and lower blade bodies 7 and 5 when pressed or returned.

Therefore, it cannot be said that the removal of beard dregs by the removal plate 9 is necessarily performed well.

In addition, in the conventional structure, since the cutout groove 2 is formed in the top plate 8, beard scum and soap that cannot be accommodated between the upper and lower blade bodies 7 and 5 pass through the top surface of the top plate 8 and accumulate in the cutout groove 2. There was also a flaw that was hard to overlook.

Purpose The purpose of this invention is to solve the above-mentioned deficiencies of the prior art by devising a locking structure between the removal plate and the bowed part to stabilize the forward and backward movement direction of the removal plate, thereby making it possible to accommodate and remove beard dregs. It is an object of the present invention to provide a two-blade razor with a beard dregs removal plate that is of good quality and has a cutout groove formed in the base of the blade holder to prevent beard dregs and soap from accumulating in the notch groove. .

EXAMPLE Hereinafter, an example embodying this invention will be explained with reference to FIGS. 1 and 2. 1 is a plastic blade holder that is removably fitted into a holder (not shown); A bowed portion 3 is formed at the rear end by cutting out a long hole-shaped notch groove 2 extending in the left-right direction.

Reference numeral 3a designates a protrusion extending rearward from the center of the rear edge of the bow tension portion 3, and reference numeral 4 designates a finger rest protruding upward from the rear edge of the protrusion 3a. It has a rectangular parallelepiped shape,
As shown in FIG. 2, it forms a step shape with the upper surface 3b of the bow tension section 3.

The finger rest 4a is an engagement surface formed on the front side of the part 4, and has a substantially planar shape extending a certain width along the bowed part 3.

This blade holder has a lower blade body 5, a spacer 6,
The upper blade body 7 and the top plate 8 are sequentially stacked on top of each other, and the upper and lower blade bodies 7, 5 and the spacer 6 are fixed to the base 1 by a projection 8a on the lower surface of the top plate 8.

6a is an escape groove cut out in the center of the rear end of the spacer 6.

Reference numeral 9 denotes a removal plate interposed between the upper and lower blade bodies 7 and 5, and the spacer 6 is loosely fitted into a loosely fitting hole 10 in the center thereof.

11 is a spacer 6 at the center of the rear edge 10a of the loose fitting hole 10.
A protrusion protrudingly provided corresponding to the relief groove 6a of the second
As shown in the figure, its tip is always interposed between the upper and lower blade bodies 7 and 5.

Reference numeral 12 indicates a protrusion extending rearward from the center of the rear edge of the exclusion plate 9, and reference numeral 13 indicates an engagement recess formed at the rear edge of the protrusion 12, which extends downward from both sides thereof. A retaining piece 14 is provided in a protruding manner.

The finger rest part 4 of the blade receiver base 1 is fitted into this engagement recess 13 , and the finger rest has an engagement surface 4 a of the part 4 engaged with an engagement surface 13 a of the engagement recess 13 . At the same time, as shown in FIG.
They are arranged with a slight gap (approximately 0.2 rrrm).

Now, if shavings are accumulated between the front ends of the upper and lower blade bodies 7.5 when shaving with the 2-power razor with the shavings removing plate configured as described above, the blade holder should be moved against the fingers of the stand 1. When the hook part 4 is pressed, the bow part 3 of the blade receiver is bent due to the extra space of the notch groove 2 of the base 1 and the elasticity of the bow part 3 itself, and accordingly, the finger rest is held in place by the part 4. The surface 4a moves forward and the removal plate 9 is moved forward, making it possible to remove the dirt between the front ends of the upper and lower blade bodies 7 and 5.

At this time, since the engagement surface 4a of the finger hook part 4 is planar, the engagement surface 4a of the engagement recess 13 of the exclusion plate 9
3a, the finger rest uniformly transmits the pressing force on the part 4 to the removal plate 9, and accurately moves the removal plate 9 forward without tilting.

Also, the protrusion 11 of the loose fitting hole 10 of the exclusion plate 9 is always connected to the upper and lower blade bodies 7.
, 5, even if the removal plate 9 moves forward, the rear edge 10a of the loose fitting hole 10 moves smoothly without being caught by the rear edge of the upper and lower blade bodies 7, 5.

At this time, since the relief groove 6a is notched in the spacer 6, the projection piece 11 is fitted as the exclusion plate 9 moves forward, and the removal plate 9
progress will not be thwarted.

Next, when the pressing force of the finger hook part 4 is released, the bow tension part 3 returns to its original position due to its elasticity, and accordingly, the rear end surface 3c of the bow tension part 3 presses the engagement piece 14 of the removal plate 9, so that the finger catch is removed. The plate 9 moves backward and returns to its original position.

At this time, since the engaging pieces 14 are located at three locations on the exclusion plate 9 spaced apart from each other, the return force of the bow tension part 3 is transferred to the exclusion plate 9.
to accurately move the exclusion plate 9 backward without tilting.

The dual-power razor with a dregs removal plate configured as described above can also be configured as follows.

(a) As shown in FIG. 3, the projecting piece 11 is triangular, the spacer 6 is divided into two parts, and the gap between the two parts is used as an escape groove 6a.

(b) Forming a plurality of protrusions 11 and corresponding reliefs 1lJ6a.

effect This invention described in detail above has the following effects.

(a) The blade holder is provided with a finger rest protruding upward from the bow part 3 of the base 1 in a step-like manner, and this finger rest is provided on the front side of the part 4. A substantially planar engagement surface 4a extending a certain width along the bowed part 3 is formed, and an engagement recess 1 into which the finger hook part 4 is fitted is formed at the center of the rear end of the exclusion plate 9.
3, the removal plate 9 can be accurately moved forward without tilting, and beard dregs can be removed reliably.

(b) On both sides of the engagement recess 13, the rear end surface 3 of the bow tension section 3 is provided.
Since the pair of retaining pieces 14 that engage with the upper and lower blades 14 are formed to face downward, the removal plate 9 can be accurately moved backward without tilting, and there is no space between the front ends of the upper and lower blade bodies 7 and 5. It is possible to maintain a constant formation of a beard dwarf storage space.

(c) Since the finger hook portion 4 is fitted into the engagement recess 13, it is possible to prevent the displacement plate 9 from swinging laterally in the left-right direction when the displacement plate 9 is moved back and forth.

Therefore, with these (a), (b), and (c), the finger hook stabilizes the forward and backward movement direction of the removal plate 9 even if there is a slight change in the pressing force direction on the part 4, and it is possible to accommodate beard dregs and to Exclusion can be made good.

2) Since the cutout groove 2 is formed at the rear end of the blade holder 1, the pressing force against the bow tension part 3 is applied to the gripping side blade holder 1, and most of the pressing force is not applied to the top plate 8. First, when the razor is used frequently, the top plate 8 and the blade holder can prevent loosening between the base 1 and eliminate looseness as much as possible, and also prevent hair that cannot be accommodated between the upper and lower blade bodies 7.5. Dirt and soap hardly accumulate in the notch groove 2, making it sanitary.
