Description

  The present invention relates to a T-type safety razor, and more particularly, to a T-type safety razor having a blade cover that wraps a razor blade.

  Various types of T-type safety razors have been proposed because they are very convenient to use by hand, and in recent years, the development of so-called disposable ones has also progressed. In this type of disposable T-type safety razor, the razor blade portion is wrapped with a blade cover.

  Since the conventional blade cover is formed as a separate body from the main body, the blade cover may be separated from the main body and roll on the bathroom washroom as it is. This kind of blade cover is small and difficult to find because it is indistinguishable from the tiles and joints of the washing place, and in some cases it is stepped on without knowing that this blade cover has fallen There was a thing.

For this reason, the present inventors have proposed a T-type safety razor in which the blade cover is rotatable with respect to the head in Patent Document 1, for example. Thereby, since the blade cover is connected to the main body side and does not fall off, the above-described problems are eliminated.
Japanese Patent Laid-Open No. 2003-236272, summary, representative diagram

  The invention of Patent Document 1 was made for the purpose of “further improving the usability of a T-type safety razor having this kind of blade cover”. As shown in FIGS. A T-type safety razor in which a head holding a razor blade that is orthogonal to the head is connected, and the head and the razor blade held by the head are encased in a blade cover, the grip to the head The connection is performed by two substantially plate-shaped connecting portions that form a finger insertion space between them, and when the razor blade or the like is wrapped in the blade cover, the head or the razor blade is formed. A first engaging portion that engages with the first locking portion, and when the blade cover is removed and rotated to the inside of the grip, the grip To form a second engagement portion engaged with the second locking portion is one having a structure such that "the formation of the projecting portion that will face in the finger insertion space.

  According to the T-type safety razor disclosed in Patent Document 1, “the blade cover 40 that is in the open state can be reliably maintained in both the enveloping state and the open state of the razor blade 30 by the blade cover 40. It can be easily performed by inserting a finger into the finger insertion space 16 formed between the two connecting portions 15 ”(Patent Literature). As shown in FIG. 9, the removed blade cover is located below the grip connecting portion, and may become an obstacle when the razor is used.

  Therefore, the present inventors have completed the present invention as a result of various studies on how to prevent the blade cover from getting in the way when using the T-shaped razor.

  That is, an object of the present invention is to provide a T-type safety razor that can keep the blade cover attached and can prevent the blade cover from becoming an obstacle at the time of use.

In order to solve the above problems, first, the means taken by the invention according to claim 1 will be described with reference numerals used in the description of the best mode described below.
“A head 20 that holds a razor blade 21 that is orthogonal to the grip 10 is connected to the blade support 11 at the tip of the grip 10, and the head 20 and the razor blade 21 held by the head 20 are connected by a blade cover 30. In the T-shaped safety razor 100 that can be wrapped,
The blade cover 30 includes a cover portion 30 a that covers the lower surface of the head 20, and a rotating arm 32 that is integrally formed on both sides of the cover portion 30 a and extends toward both sides of the blade body support portion 11. And
A T-shaped safety razor 100 having a blade cover 30 characterized in that a rotating arm 32 is connected to both sides of the distal end of the blade support 11 by a rotating shaft 31.
It is.

  That is, the T-type safety razor 100 according to claim 1 is orthogonal to the grip 10 on the blade support 11 formed at the tip of the grip 10, as shown in FIGS. The head 20 holding the razor blade 21 to be connected is connected, and the head 20 and the razor blade 21 held by the head 20 are wrapped by the blade cover 30. The “connection of the head 20” means that the head 20 is of a replaceable blade type and can be replaced with the grip 10, and is integrated with the grip 10 together with the grip 10. This includes cases where it is disposable.

  Further, as shown in FIGS. 4A and 4B, the T-type safety razor 100 according to claim 1 includes a blade cover 30, a cover portion 30a that covers the lower surface of the head 20, and the cover portion 30a. And the pivot arm 32 of the blade cover 30 is rotatably coupled to the both ends of the blade support 11 of the grip 10 by a pivot shaft 31. It is a thing.

  In the T-type safety razor 100 according to the present invention configured as described above, the head 20 and the razor blade 21 are almost completely covered by the blade cover 30 when not used, as shown in FIG. Wrapped up. That is, as shown in FIG. 2B, the cover part 30 a constituting the blade cover 30 completely covers the lower surface of the head 20. For this reason, in the case where the T-type safety razor 100 is held in the hand or the one that has been put in the bag is taken out, the finger is prevented from being damaged by the razor blade 21.

  Next, in order to use the T-type safety razor 100, the blade cover 30 is raised from the state shown in FIG. 4A to the state shown in FIG. At this time, the cover portion 30a of the blade cover 30 moves to the upper side of the grip 10, and the lower side of the head 20 is completely open as shown in FIG. 4B. Therefore, since the razor blade 21 is exposed on the lower side of the grip 10, shaving and wasteful shaving can be performed without any obstruction. Of course, the blade cover 30 does not come off during use such as shaving. This is because the blade cover 30 has both rotating arms 32 connected to both ends of the tip of the grip 10 by a rotating shaft 31.

  In the best mode to be described later, as shown in FIG. 1 and the like, an opening / closing protrusion 34 on which a finger is hung is integrally formed on the outside of the cover portion 30a of the blade cover 30. The blade cover 30 can be easily opened and closed by putting a finger on it and pulling it.

  Therefore, in the T-type safety razor 100 according to the first aspect, the blade cover 30 remains attached and the blade cover 30 does not get in the way at the time of use. It is easy to use and easy to use.

In order to solve the above-mentioned problem, the means taken by the invention according to claim 2 relates to the T-type safety razor 100 having the blade cover 30 according to claim 1,
“Two front and rear locking portions 33 to be locked to one stopper 25 formed on the arm portion 22 on the head 20 side of the rotary arm 32 on the blade cover 30 side, in the immediate vicinity of the rotation shaft 31. That formed "
It is.

  That is, in the T-type safety razor 100 according to the second aspect, as shown in FIGS. 4A and 4B, for example, the two locking portions 33 are formed on the rotating arm 32 on the blade cover 30 side. These locking portions 33 are located in the immediate vicinity of the rotation shaft 31 and are on a circumference around the rotation shaft 31. These engaging portions 33 are engaged with the stoppers 25 formed on the arm portions 22 of the head 20 fixed to the grip 10, and the blade cover 30 is closed (FIG. 4). In a), the first locking portion 33 is located on the right side of the stopper 25 on the head 20 side in the figure, and maintains the closed state of the blade cover 30.

  On the other hand, in FIG. 4B showing the state in which the blade cover 30 is opened, the first locking portion 33 gets over the stopper 25 and is positioned above, and the second locking portion 33 is the head 20. The blade cover 30 is maintained in the released state by being engaged with the right side of the stopper 25 in the figure. Of course, if the head 20 is moved downward in this state, the blade cover 30 is rotated in the closing direction. However, when the T-type safety razor 100 is used, the head 20 is moved upward. The blade cover 30 is never closed.

  Therefore, the T-type safety razor 100 according to the second aspect exhibits the same function as that of the first aspect, and can reliably maintain the released state and the closed state of the blade cover 30. .

As described above, in the present invention,
“A head 20 that holds a razor blade 21 that is orthogonal to the grip 10 is connected to the blade support 11 at the tip of the grip 10, and the head 20 and the razor blade 21 held by the head 20 are connected by a blade cover 30. In the T-shaped safety razor 100 that can be wrapped,
The blade cover 30 includes a cover portion 30 a that covers the lower surface of the head 20, and a rotating arm 32 that is integrally formed on both sides of the cover portion 30 a and extends toward both sides of the blade body support portion 11. And
The rotating arm 32 is connected to both sides of the tip of the blade support 11 so as to be rotatable by the rotating shaft 31.
