  By the way, in the case of the electric razor as described above, since the portion for accommodating the head portion is formed larger than the head portion so as to easily accommodate the head portion of the electric razor, the electric razor is accommodated in the case. However, the head portion swings with respect to the main body portion and rattling occurs.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an electric razor case that can suppress shakiness of the electric razor.

  In order to solve the above-mentioned problem, the invention according to claim 1 is an electric razor comprising a main body that can be gripped by a user and a head that is provided so as to be swingable in at least one direction with respect to the main body. An electric razor case to be accommodated, wherein a housing part capable of accommodating the electric razor is formed straddling each other, and includes first and second case members connected to each other by a hinge part; The gist is that at least one of the one case member and the second case member is provided with a pressing portion that presses the head portion on the other case member side in the swing direction of the head portion.

  In this invention, while the accommodating part which can accommodate an electric shaver is formed ranging over mutually, it is provided with the 1st and 2nd case member mutually connected by the hinge part, and the 1st case member and the 2nd case member At least one of them is provided with a pressing portion that presses the head portion on the other case member side in the swing direction of the head portion. Thus, the head portion is pressed against the other case member side in the swing direction of the head portion by the pressing portion provided on the one case member, so that the head portion is relatively relative to the main body portion in the case. Swing can be suppressed. For this reason, shakiness of the electric razor (head part) in the case can be suppressed.

  According to a second aspect of the present invention, in the electric razor case according to the first aspect, the electric razor is configured to be able to lock a swing of the head portion at a predetermined position. The gist of the invention is that the head portion is configured to be elastically deformable in the direction opposite to the pressing direction when contacting the head portion with a predetermined pressing force or more when the head portion is locked.

  In this invention, the electric razor is configured so that the swing of the head portion can be locked at a predetermined position, and the pressing portion is in contact with the head portion at a predetermined pressing force or more when the head portion is locked. Is configured to be elastically deformable on the side opposite to the pressing direction. As described above, when the pressing portion is in contact with the head portion at a predetermined pressing force or more when the head portion is locked, the head portion is deformed to the opposite side to the pressing direction. In addition, an excessive load between cases can be prevented.

  According to a third aspect of the present invention, in the case of the electric shaver according to the first or second aspect, the hinge portion is provided at one end in the longitudinal direction in which the main body portion and the head portion are arranged, The gist is that the pressing portion is provided near the hinge portion of at least one of the first case member and the second case member.

  In the present invention, the hinge portion is provided at one end in the longitudinal direction in which the main body portion and the head portion are arranged, and the pressing portion is provided near at least one hinge portion of the first case member and the second case member. As described above, since the pressing portion is arranged closer to the hinge portion, the reaction force generated when the pressing portion abuts on the head portion can be reduced. Therefore, the first case member and the second case member are centered on the hinge portion. The case can be easily closed by rotating it relatively to each other, and the convenience of the case can be improved.

  According to a fourth aspect of the present invention, in the electric razor case according to any one of the first to third aspects, the first case member is a main body side case member, and the second case member is the main body. A lid-side case member that is pivoted through the hinge portion to be opened and closed with respect to the side case member, and the pressing portion is configured to be elastically deformable and provided on the lid-side case member. The gist.

  In this invention, while the 1st case member is a main body side case member, the 2nd case member is a lid side case member rotated and opened and closed with respect to a main body side case member via a hinge part. That is, the case is opened and closed by rotating the lid side case member in a state where the electric razor is accommodated in the accommodating portion of the main body side case member. In such a configuration, since the pressing portion is configured to be elastically deformable, for example, when the pressing portion is provided in the main body side case member, the pressing portion is elastically deformed when the electric razor is accommodated in the main body side case member. It is difficult to stably store an electric razor. Therefore, it is possible to stably accommodate the electric razor by providing the pressing portion on the lid-side case member, that is, by not providing the pressing portion on the main body-side case member that first accommodates the electric razor. .

The motor 5 is electrically connected to a power source 7 (see FIG. 1) housed in the grip body 2 and is operated by an operation switch (not shown) provided on the front side of the grip body 2. It is driven based on this.

  A case 10 that accommodates the electric shaver 1 configured as described above is provided so as to be relatively rotatable by a main body side case member 11 and a hinge portion 12 provided at one longitudinal end of the main body side case member 11. And a lid-side case member 13. That is, the case 10 of the present embodiment is configured to be able to open and close the lid-side case member 13 around the hinge portion 12 with respect to the main body-side case member 11.

  Further, the case 10 composed of the main body side case member 11 and the lid side case member 13 includes a main body housing portion 20 for housing and supporting the grip main body portion 2 of the electric razor 1 and the head portion 3 as shown in FIGS. The head accommodating portion 21 is formed so as to straddle both case members 11 and 13. That is, the main body side case member 11 is provided with a main body accommodating recess 20a and a head accommodating recess 21a, and the lid side case member 13 is formed with a main body accommodating recess 20b and a head accommodating recess 21b.

  The main body accommodating portion 20 includes at least five abutment support portions 22 a to 22 e that abut on the grip main body portion 2 of the electric razor 1. The contact support portions 22a to 22e are provided on the body side case member 11, and contact support portions 22a and 22b that contact the rear surface side upper end portion 2a and the lower end portion 2b of the grip main body portion 2, and the contact support portions. 22a and 22b, a contact support portion 22c that contacts the rear surface 2c of the grip main body 2, and a front side upper end 2d and a lower end of the grip main body 2 that are provided on the lid-side case member 13. It comprises contact support portions 22d and 22e that contact 2e. When the grip main body 2 of the electric razor 1 is accommodated in the main body accommodating portion 20 by the plurality of abutting support portions 22a to 22e having such a configuration, it is supported by many abutting support portions 22a to 22e. Therefore, it can be accommodated in a stable state.

  The head accommodating portion 21 is an accommodating space near the hinge portion 12 on one end side in the longitudinal direction of the main body side case member 11 and the lid side case member 13, and the front and rear of the head portion 3 that slides in the front and rear direction (thickness direction). An accommodation space having a size that can sufficiently correspond to the thickness in the direction is formed. Further, a cover portion 30 made of an elastic member such as an elastomer is mounted at a position corresponding to the head portion 3 of the lid side case member 13 in the head accommodating portion 21.

  The cover portion 30 has a pressing protrusion formed by projecting toward the main body side case member 11 (head portion 3) side and having a predetermined space X between the cover portion 30 and the lid side case member 13. The part 31 is formed at the center in the width direction. When the head portion 3 is in a swingable state, the pressing protrusion 31 abuts against the head portion 3 to generate a predetermined pressing force, and the head portion is formed between the pressing protrusion 31 and the bottom portion of the main body side case member 11. 3 is sandwiched. Further, when the head portion 3 is locked by the locking mechanism and the head portion 3 is positioned on the pressing protrusion 31 side, the pressing protrusion 31 is a space portion X in which the pressing protrusion 31 is opposite to the protruding direction. It is configured so that excessive force does not occur between the head portion 3 and the case 10 (the lid-side case member 13) by elastic deformation. For this reason, an excessive load is not generated on the locking mechanism for locking the head portion 3 and the hinge portion 12 or the like for rotatably connecting the case members 11 and 13.

  Further, a slide member 35 slidable in the longitudinal direction is provided at the end of the lid side case member 13 on the opposite side of the hinge portion 12 in the longitudinal direction. This slide member 35 is in a state where the lid side case member 13 and the main body side case member 11 are in close contact with each other, that is, in a closed state where the opening of the main body side case member 11 is closed by the lid side case member 13. The casing 11 is engaged with the lower end portion 11 a of the member 11, and the relative rotation of the case members 11 and 13 is restricted to accommodate the electric razor 1.

  In the case 10 configured as described above, the pressing protrusion 31 is provided near the hinge portion 12 on one end side in the longitudinal direction of the lid-side case member 13, so that it is pressed when the lid-side case member 13 is rotated and closed. The reaction force generated when the protrusion 31 and the head portion 3 abut can be reduced. Thereby, since the case 10 can be easily made into a closed state by rotating the lid side case member 13 to the main body side case member 11 side, the convenience of the case 10 can be improved. . Further, since the pressing protrusion 31 is formed on the lid-side case member 13, when the electric razor 1 is accommodated in the main body-side case member 11, the electric razor 1 (main body portion 2) is brought into contact with the support portions 22 a to 22 a. 22e can be supported stably.

Next, characteristic effects of the present embodiment will be described.
(1) The housing parts 20 and 21 capable of housing the electric razor 1 are formed so as to straddle each other, and are provided with a main body side case member 11 and a lid side case member 13 which are connected to each other by a hinge part 12. The side case member 13 is provided with a pressing protrusion 31 that presses the head 3 portion on the main body side case member 11 side that is the swing direction of the head portion 3. In this way, the head unit 3 is pressed in the case 10 on the main body side case member 11 side, which is the swing direction of the head unit 3, by the pressing protrusion 31 provided on the lid side case member 13. Swinging relative to the grip main body 2 can be suppressed. For this reason, shakiness of the electric razor 1 (head part 3) in the case 10 can be suppressed.

  (2) The electric razor 1 is configured so that the swing of the head portion 3 can be locked at a predetermined position, and the pressing protrusion 31 is not less than a predetermined pressing force with the head portion 3 when the head portion 3 is locked. When abutting, it is configured to be elastically deformable on the side opposite to the pressing direction. As described above, when the pressing protrusion 31 is brought into contact with the head portion 3 with a predetermined pressing force or more when the head portion 3 is locked, the pressing portion 31 is deformed to the opposite side to the pressing direction. Can be prevented from causing an excessive load between the head unit 3 and the case 10.

  (3) The hinge portion 12 is provided at one end portion in the longitudinal direction in which the grip main body portion 2 and the head portion 3 are arranged, and the pressing protrusion 31 is provided near the hinge portion 12 of the lid side case member 13. Thus, by disposing the pressing projection 31 closer to the hinge portion 12, the reaction force generated by the pressing projection 31 coming into contact with the head portion 3 can be reduced. When the case member 13 is rotated relative to the center of the hinge portion 12, the case 10 (the lid-side case member 13) can be easily closed, and the convenience of the case 10 can be improved.

  (4) The case 10 is opened and closed by rotating the lid side case member 13 in a state where the electric razor 1 is accommodated in the accommodating portions 20 and 21 (the main body accommodating concave portion 20a and the head accommodating concave portion 21a) of the main body side case member 11. Is. In such a configuration, since the pressing protrusion 31 is configured to be elastically deformable, for example, when the pressing protrusion is provided in the main body side case member 11, the pressing protrusion 31 is accommodated when the electric shaver 1 is accommodated in the main body side case member 11. Since the portion is elastically deformed, it is difficult to stably accommodate the electric razor 1. Therefore, the configuration in which the pressing protrusion 31 is provided on the lid-side case member 13, that is, the configuration in which the pressing protrusion 31 is not provided in the main body-side case member 11 that first accommodates the electric razor 1, the electric razor 1 is disposed on the main body side. It becomes possible to accommodate the case member 11 in a stable state.

  (5) Since the pressing protrusion 31 is formed so as to have the predetermined space portion X between the cover portion 30 and the lid-side case member 13, the space portion is brought into contact with the head portion 3 and the pressing protrusion 31. The cover 30 (the pressing protrusion 31) can be easily deformed by X. For this reason, it is possible to suppress an excessive pressing force from acting on the head portion 3.

In addition, you may change embodiment of this invention as follows.
In the above embodiment, the pressing protrusion 31 is provided on the lid side case member 13, but in addition to this, the pressing protrusion is provided on the main body side case member 11, or the pressing protrusion is provided only on the main body side case member 11. You may employ | adopt the structure which provides a part.

  In the above embodiment, by forming the space X between the pressing protrusion 31 and the lid side case member 13, the pressing protrusion 31 is elastically deformed toward the lid side case member 13 when the head portion 3 is locked. Although it is configured easily, a pressing protrusion having a configuration in which the space portion X is also filled with an elastomer or the like may be employed.

  In the above embodiment, although not particularly mentioned, a configuration may be adopted in which a gel-like member that can be elastically deformed is filled in the space X of the pressing protrusion 31. With such a configuration, the elastic deformation of the gel-like member can be used in addition to the elastic deformation of the pressing protrusion 31 (cover portion 30). It becomes possible to suppress the shakiness of 3.

  In the above embodiment, although not particularly mentioned, a configuration in which a spring member is provided in the space X of the pressing protrusion 31 may be adopted. With such a configuration, the elastic deformation of the spring member can be used in addition to the elastic deformation of the pressing protrusion 31 (cover portion 30). It becomes possible to suppress the shakiness of 3.
