Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a hand-held type hair dryer having a stand, and more specifically, to a device body supported swingably on a hand-held handle body. It concerns a support structure.

[Prior art]

This type of hair dryer has been well received because it is very convenient to use, since both hands can be used freely when performing hair blow and the like.

A conventional hair dryer 1 will be described with reference to FIGS. 2 (a) and 2 (b).

The main body 2 attachable to the stand 7 is bendable in the direction indicated by the arrow in the figure with the handle portion 6 as a boundary.
Further, although not shown, a heater, a blower fan, etc. are provided inside the main body 2, and the power cord 6a taken out from the handle portion 6 has a handle portion 6 for supporting the main body 2.
Is attached to the stand 7, and is housed inside this.

On the other hand, if you connect the power cord 6a to an outlet not shown,
The main body 2 is adapted to be energized while being mounted on the stand 7. Further, if the knob 4 for height adjustment provided on the side surface of the stand 7 is operated, the stand 7
The height position of the main body 2 mounted on the can be adjusted slightly. That is, the handle portion 6 can be used as well as the state where the handle portion 6 is mounted on the stand 7. A slide type (or push button type) power switch 3 is provided on the side surface of the handle portion 6.

The main body 2, which is swingably supported by the handle portion 6 as described above, is always elastically biased clockwise in FIG. 2A by the quick spring 8 (see FIG. 2B). The quick spring 8 has a rotational moment in the counterclockwise direction, which is caused by a considerable distance from the swing center of the main body 2 to the position of the center of gravity of the main body 2 (the position of x in FIG. 4A). Acts to offset the.

A snap 10 that is constantly elastically urged by a spring 9 is provided inside the handle portion 6.
A tip portion of 10 can be elastically engaged with an engagement hole 11a formed in the snap plate 11 in the main body 2. A plurality of the engaging holes 11a are provided on an arc locus centered on the swing center position of the main body 2, and the operator swings the main body 2 so that the engaging holes 11a are appropriately positioned. By appropriately and selectively engaging the snaps 10 with each other, the elevation angle of the main body 2 with respect to the handle portion 6 is adjusted.

[Problems to be solved by the device]

By the way, in the conventional hair dryer 1 configured as described above, when the center of gravity of the main body 2 is located laterally (horizontally) with respect to the swing center of the main body 2, the rotational moment of the downward direction is Maximum value. Therefore, since the spring constant of the quick spring 8 is set based on the value at that time, the elevation angle of the main body 2 with respect to the handle portion 6 increases, and the rotational moment of the rotational moment increases as the main body 2 moves upward. The value decreases. In such a state, the elastic force of the quick spring 8 acts as a resistance against the operator when the elevation angle of the main body is raised or lowered, and the impact of the snap 10 on the engagement hole 11a when the snap 10 is engaged or disengaged. In addition to the mechanical resistance, a large operating force is required for the operator when adjusting the elevation angle, which is not convenient.

Therefore, an object of the present invention is to provide a hair drying device having a function capable of easily adjusting the main body to an arbitrary elevation angle position with a constant light operating force.

[Means for Solving the Problems]

In order to achieve the above object, the main means adopted by the present invention is, in the gist thereof, an apparatus for drying hair by blowing air from a main body swingably supported by a handle body. The main body is swingably connected at a substantially center of gravity position of the main body, and an elastic member is slidably brought into contact with a connecting portion of the main body with respect to the handle body so that a swing resistance is exerted on the main body when the main body swings. It is a hair drying device according to the point that a resistance imparting mechanism that imparts elastically and steplessly is provided.

[Action]

In the hair dryer according to the present invention, since the main body is swingably supported by the handle body at the substantially center of gravity position of the main body, the main body itself has a rotational moment around the swing center of the main body. Does not work. Therefore, it is not necessary to provide a spring or the like for canceling the rotational moment as in the case of the conventional device, and the operation force for adjusting the elevation angle of the main body is always a stable and constant value.

Further, due to the action of the resistance imparting mechanism provided at the connecting portion of the main body with respect to the handle body, an appropriate resistance for maintaining the elevation angle position of the main body constant is elastically and steplessly imparted to the handle body. To be done. Therefore, the shock resistance at the time of engaging and disengaging the snap with respect to the engagement hole does not act unlike the case of the conventional device, and the main body can be easily adjusted to an arbitrary elevation angle position with a light operating force.
