Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a stand type hair dryer in which a head insertion body is supported on a slidable stand.

An embodiment of the present invention will be described below with reference to the drawings.

In the drawings, reference numeral 1 denotes a stand, which is composed of a base 2, a fixed support 3, and a movable support 4.

The movable column 4 is slidably inserted into the fixed column 3 below -L, and can be set to an arbitrary height using a height adjustment device provided at the top of the fixed column 3.

The configuration of the height adjustment device will be explained with reference to FIGS. 4 to 6.

Reference numeral 5 denotes a base of the height adjustment device, which is made of polypropylene.

Reference numeral 6 denotes a bearing section provided on the base, and a brake section 7 is provided at the lower end of this bearing section.

A vertical slit 8 is formed in the brake part 7, and the brake part 7 can be freely elastically deformed in the inner radial direction.

Insert the base 6 into the upper part of the fixed column 3 and fix it with screws 9.

A screw hole into which a screw 9 is screwed is formed in the fixed column 3.

Reference numeral 10 denotes a presser ring fitted around the outer periphery of the brake part 7, and is made of stainless steel.

The holding ring 10 is fitted into the brake part 7 before the base 6 is attached to the fixed support 3.

11 is a screw seat 1 that is fixed to the fixed column 3 with an adjustment screw.
2 is screwed together.

The adjusting screw 11 is attached such that the tip of the adjusting screw 11 passes through the fixed column 3 and joins to the outer periphery of the presser ring 10.

By tightening the adjusting screw 11 and strongly pressing the retaining ring 10, the brake part 7 strongly presses against the outer periphery of the movable column 4, thereby fixing the movable column 4.

When the adjusting screw 11 is completely loosened, the tip of the adjusting screw 11 is separated from the presser ring 10.

However, since the brake part 7 is pressed in the inner radial direction by the spring pressure of the retainer ring 10, the brake part 7 contacts the outer periphery of the movable column 4 with an appropriate pressing force, and as a result, the movable column 4 automatically moves. It does not fall.

Therefore, the vertical height is adjusted in this state.

A cap 13 is fixed to the lower end of the movable support 4 to prevent sliding noise when sliding inside the fixed support 3.

The cap 13 is made of polypropylene and is press-fitted onto the movable column 4.

The lower end of the movable column 4 is formed into a trumpet shape that expands toward the outer periphery.

This trumpet shape facilitates press-fitting of the stopper 14.

When the movable column 4 is still raised upward, it comes into contact with a stopper 14 formed on the upper side of the fixed column 3 to prevent the movable column 4 from being pulled out.

15 is a rubber inserted into the lower end of the fixed column 3 and fixed with adhesive.

Reference numeral 16 denotes a ring-shaped recess formed on the outer peripheral side of the lower end of the fixed column 3.

The fixed support 3 is fixed to the base 2 as shown in FIG.

Reference numeral 17 denotes a fixing screw, which is screwed into the ring-shaped recess 16.

The fixed column 3 is now completely fixed to the base 2.

7 and 8 show the structure of the base 2, and 18 is a concrete weight.

19 is a bottom plate made of a steel plate, and 20 is a top cover made of a steel plate.

21 is a connection stand made of polypropylene.

The base 2 is assembled as follows.

A nut 27 is screwed onto the tip of the bolt 24 protruding from the central support portion 23 of the connection base 21 via a washer 25 and a spring washer 26, thereby connecting the bottom plate 19 and the upper cover 20.
is fixed.

The central support portion 23 of the connection stand 21 is an insertion hole into which the fixed support 3 is inserted, and the fixed support 3 is inserted and fixed here as described above.

When the fixed column 3 is fixed, the rubber 15 is almost in contact with the tip of the bolt 24.

Therefore, even if the stopper 13 collides with the rubber 15 when the movable column 4 is lowered to the lowest position, the rubber 15 is stopped by the bolt 24.

The rubber 15 has a cushioning effect when the movable support 4 is lowered.

The connection stand 21 has a central support part 23 at the center, but has an umbrella-shaped part 28 on the outside, and the lower end of the outer periphery of the umbrella-shaped part 26 is joined to the upper surface of the upper cover 20.

29 is a reinforcing ring formed inside the umbrella-shaped portion 28; 30;
Reference numeral 31 denotes reinforcing ribs, which are provided in large numbers at approximately equal pitches.

Since the connection stand 21 is made of polypropylene, it has a reinforced structure as described above.

32 is a ring-shaped protrusion formed on the bottom plate 19 and has a reinforcing function.

Reference numeral 33 denotes an outer periphery rising portion formed by bending the outer periphery of the bottom plate 19 upward into a ring shape.

Reference numeral 34 denotes an outer circumferential base portion formed by bending the outer circumference of the upper cover into a ring shape (downward).

The outer circumferential base portion 34 and the outer circumferential rising portion 33 are formed to overlap so that a gap is formed between them.

Reference numeral 35 has a plastic or rubber backing that surrounds the outer circumferential base portion 34 from below.

Of course, it has a ring-like shape.

This backing has a downward ring-shaped groove 35 formed on the upper inner periphery side, and this groove 36 is connected to the outer periphery rising portion 3.
It is fitted in 3.

The backing 35 is thereby held on the bottom plate 19.

Further, an upward ring-shaped groove 37 is formed on the lower outer periphery of the backing 35.

The skirt portion 34 is inserted into this groove portion 37.

The width and depth of the groove portion 37 are sufficiently large.

For this reason, even if the weight 18 is made of concrete and has variations in dimensions, there is no problem in inserting the base portion 34.

That is, the backing 35 is attached to the rising portion 33 of the bottom plate 19.
Therefore, variations in the thickness of the weight 18 can be absorbed by loosely fitting the base portion 34 into the groove portion 37.

Reference numeral 38 denotes a support base that supports the aforementioned head insertion body and is fixed to the upper end of the movable column 4.

(FIGS. 2 and 4) The movable support 4 is a hollow pipe, and is fixed by press-fitting a support 38 into the pipe.

The support stand 38 has four ring-shaped parts 39 formed therein.

Reference numeral 40 denotes a head insertion body, which is supported by a support column 41 so as to be vertically and vertically suspended.

The support column 41 is inserted into the support base 38, and the fixing screw 4

, thereby fixing the support column to the support base 38.

Reference numeral 43 denotes a hook for hanging the hanging portion 45 of the controller 44, which is fixed to the support column 41.

The hook 43 is made of polypropylene and includes a C-shaped landing portion 46.

The hook 43 is attached to the support column 41 by elastically clamping the support column 41 with the elastic portion 46 .

This installation is extremely easy.

As shown in FIGS. 3, 4, and 9, the head insertion main body 4
0 is composed of a base part 47 in which a heat source part and a blower part are housed, and a hood 48.

The base portion 47 has an approximately half-dome shape and is made of plastic.

The support substrate 49 is made of a steel plate.

The air blower has a shaded coil type motor 41 and an axial flow fan 50.
The motor 49 is attached to the upper center of the support substrate 49 with a screw.

51 is a ventilation hole formed in the center of the support substrate 49.

Support parts 52 are formed concentrically and at substantially equal pitches on the outer side of the ventilation hole 51, and are formed by cutting the support substrate 49 upward.

By cutting and raising the support substrate 49, the same number of holes as the support portions 52 are formed.

This hole becomes a ventilation hole 53 for heating.

Reference numeral 54 denotes a mica insulating plate, which is fixed to the support portion 52 with a caulking tool.

A heater wire 55 is attached to the insulating plate 54 to constitute a heating section.

Heater wire 55 (A glass-based core wire 55 is passed through the heater wire 55 for reinforcement.

) is installed on the outer peripheral side of the axial fan 50 and spaced apart from the support substrate 49.

56 is a terminal plate attached to the support substrate 49.

The heater wire 55 is connected to a lead wire via a terminal plate 56.

Reference numeral 57 covers the air blowing section and the heating section with a card board having an outward blowing guide support 58.

This card board 57 is fixed to the base portion 47 with screws 59.

Reference numeral 60 denotes an external vent hole formed at the center of the upper part of the base portion 47. A guide plate 61 is formed on the base portion 47 inside the vent hole 60, and this guide plate faces the direction of the blower.

A large recess 64 consisting of a standing wall 62 and a bottom 63 and a relatively large recess 65 extending downward from the rear end of the bottom 63 in a substantially circular arc are formed at the rear upper part of the base body 47 .

Both recesses 64 and 65 have the same width.

These two recesses 64 and 65 are connected to a relatively long arc-shaped cover 66 (made of plastic).

) A space is formed by covering it with

The cover 66 is attached as follows.

That is, the engagement protrusion 68 formed at the upper end of the cover 66 is inserted into the engagement hole 67 formed at the upper end of the recess 64, and the cover 66 is inserted into the rising part 69 formed at the lower side of the recess 65.
The cover 66 is attached by joining the lower ends of the two and screwing the screws 70 passed through the cover 66 into the rising portions 69.

71 is an elevation angle adjusting device placed in the recess 64 and fixed to the bottom 63 with a screw.

This elevation angle adjustment device 71 includes a base plate 72 and a support column support plate 74 rotatably supported on the base plate 72 by support bolts 73.
It is composed of.

Furthermore, the detailed configuration of this elevation angle adjusting device 71 will be explained with reference to FIGS. 15 and 16.

Reference numeral 74 indicates two support plates formed on the substrate 72, and reference numeral 75 indicates two support portions formed on the support column support plate 74.

The support plate 74 and the support part 75 are each connected to a washer 76 (which applies a frictional force and applies a braking force to rotation, which will be described later).

) and pass the support bolt 73 through them,
It is tightened with a nut 77.

78 is a spring washer.

79 is a hollow pipe fitted around the outer circumference of bolt 73.

This pipe penetrates the support plate 74 and the support part 75,
The nut 77 is tightened to the end surface of the pipe.

A hollow pipe 80 is fitted around the outer periphery of the hollow pipe 79.

A spiral spring 81 is wound around the outer periphery of this hollow pipe 80.

One end of the helical spring 81 is engaged with a cutout groove 82 formed on the side surface of the support portion 75, and a curved end thereof is engaged with a projection 83 formed on the base plate 72, respectively.

To engage the curved end of the helical spring 81 with the protrusion 83, first temporarily install the receiver as shown by the two-dot chain line in Fig. 16, then raise the end in the direction of the arrow to engage. It is something to do.

This gives the helical spring 81 additional force.

84.85 is a stopper formed on the side end of the support part 75, and in the state shown in FIG. prevent them from doing so.

Similarly, reference numeral 84 is a counterclockwise stopper, and a counterclockwise rotational force is applied to this elevation angle adjusting device 71 by a helical spring 81.

Further, during this rotation, braking is applied by a washer 76.

The upper end of the support column 41 is attached to the support column support plate 74 with screws 86 and nuts 87.

The upper end of the support plate 41 is flattened into a plate shape.

Since the support column 41 is hollow, it can be easily crushed.

As described above, the head insertion section 40 is suspended from the support column 41 with the elevation angle adjustment device 71, and although this elevation angle adjustment device 71 is not located at the center of gravity of the head insertion section, it is located quite close to it. be.

Therefore, the angle adjustment operation force of the head insertion portion can be reduced.

Moreover, the helical spring 81 can also be made smaller.

In addition, since the elevation angle adjustment device 71 is covered with the cover 66, there is no exposed part to the outside and the device has a good appearance.

Note that the cover 66 is provided with support columns 4 when adjusting the elevation angle.
An elongated hole 88 is formed so that 1 can move.

Further, the recess 65 accommodates a pull-out connection terminal portion 89 from the motor 49 and the heater wire 55, and a power supply connection wire 90 and a connection wire 9 of the controller 44 from the lower end of the recess 65.
1 is drawn out.

Therefore, since the connection terminal portion 89 is covered with the cover 66, it is not exposed to the outside and has a good appearance.

Further, the support column 41 is largely curved at the upper side so that the base portion 47 is separated from the support column 41, and the straight portion approaches the hood portion 48.

This is because a sufficient gap is required between the curved portion and the base portion 47 in order to allow the head insertion main body 40 to move up and down.

In addition, since the straight portion is close to the hood portion 48, the center of gravity of the head insertion portion main body 40 can be brought closer to the stand 1.
This increases stability.

Next, the structure of the hood portion 48 will be explained along FIGS. 9 to 13.

Reference numeral 90 denotes a semi-cylindrical fixed hood, and 91 denotes a semi-cylindrical movable hood, which together form a planar hood portion 48.

Four engagement holes 92 are formed on the upper side of the fixed hood 90.

93 is an engaging claw formed at the lower end of the rear half of the base portion 40;
It is set up in several places.

The fixed hood 90 is fixed to the base portion 40 by engaging the engagement claw 93 with the engagement hole 92 .

Reference numeral 94 denotes a half-ring-shaped groove formed at the lower end of the front half of the base portion 40, into which a ring 95 is fitted for tightening, and the ring 95 is further tightened by pressing the outer periphery of the engagement hole 92 of the fixed hood 90. The fixed hood 90 is reliably fixed to the base portion 40 by tightening both ends with screws 96 and nuts.

The supporting structure of fixed hood 90 is simple.

Moreover, it is easy to assemble and securely fixed.

Support arms 97 are provided on both sides of the upper end of the movable hood 91.

A circular platform 98 is formed on the inner side of the support arm 97, and a substantially elliptical recess 105 is formed on the outer side.

An elliptical ring groove 106 and a circular recess 107 are formed deep inside the recess 105 .

99 is a support hole formed to penetrate through the center of the circular base 99, and 100 is a stopper formed slightly outward from the circular base 99.

Reference numeral 101 designates a movable hood support base formed on the base portion 47, on which a protrusion 102 in which a tapping hole is formed is formed.

A base portion 103 having a semicircular inner peripheral portion 103 concentric with the protrusion 102 is provided.

The rain upper end surface 104 of the base part 103 has one stopper.

The inner peripheral portion 103 is formed to be larger than the outer diameter of the circular base 99.

To attach the movable hood 91, first
A friction plate 104 made of rubber or plastic is inserted, and then the circular base 99 is fitted into the inner peripheral part 103 so that the support hole of the movable hood 91 is fitted into the protrusion 102.

In this way, the movable hood 91 is movably supported by the protrusion 102 of the base portion 47.

Next, the washer 108, spring 109, and washer 110 are inserted into the circular recess 107, the tapping screw 111 is screwed into the tapping screw hole of the protrusion 102, and the washer 110 is pressed.

A rectangular hole 112 is formed in the washer 110.

This hole 112 is configured with two cut-out portions 113.

Reference numeral 114 denotes a rectangular protrusion formed at the tip of the protrusion 102, which is dimensioned to fit into the hole 112, and has a height approximately equal to the height of the cut-out portion 113.

Therefore, by fitting the hole 112 of the washer 102 into the protrusion 114, the washer 102 is attached to the protrusion 102 in a non-rotatable manner.

Since there is still a cut-out portion 113, remove the tapping screw 11.
1 into the tapping screw hole of the protrusion 102, the screw 111 comes into contact with the protrusion 114 and the cut-out portion 113.

Furthermore, the washer 108 and the washer 110 are made of steel plates, whereas the protrusion 114 is made of plastic integrally with the base portion 47.

The raised portion 113 of the washer 110 joins the protrusion 114 with a large surface (if the raised portion 113 does not exist, the joining area of the protrusion 114 will be equal to the thickness of the washer 110).

), the plastic protrusion 114 will not be damaged.

Reference numeral 115 is an oval-shaped cover plate made of plastic.

The temporary closure 115 is fitted into the oval recess 105 and bonded with adhesive.

The self-tapping screw 111 and the like housed in the recess 107 are completely covered with this temporary closure 115, giving a good appearance.

When the movable hood 91 is rotated and completely opened, the stopper 100 of the movable hood 91 comes into contact with the rear upper end surface 104 of the platform 103, and the movable hood 91 cannot be opened any further.

Therefore, when the movable hood 91 is completely opened, the upper end portion of the movable hood 91 does not come into contact with the outer peripheral surface of the base portion 47, so that it does not damage both.

While the movable hood 91 is still closed, the stopper 100 of the movable hood 91 contacts the front upper end surface 104 of the base portion 103, so that the movable hood 91 does not rotate any further in the closing direction.

When the movable hood 91 rotates, a braking force is applied to the movable hood 91 by the friction plate 104.

For this purpose, the movable hood 91 can be set at any opening angle.

That is, there is a splash 109 between the washer 108 and the washer 110.
The circular base 99 of the movable hood 91 is pressed against the friction plate 104 by the springs 109.

As a result, the movable hood 91 can obtain a braking force.

When the recessed movable hood 91 is rotated, a rotational force accompanying this rotation is applied to the washer 110.

That is, it is transmitted via the washer 108 and the spring 109.

Even if a rotational force is applied to the washer 110, the protrusion 114 will not be scratched by biting because the large surface of the washer 110 abuts against the cut-and-raised portion 113 as described above.

Next, regarding the shock absorbing device of the OT dynamic hood 91, FIG.
This will be described based on FIG.

A buffer 116 is made of rubber or plastic.

This is U-shaped, with 1 diagonal protrusion on one side.
17 is formed.

An insertion hole 11 is provided on the front side of the lower front end of the fixed hood 90.
A shock absorber support 119 having a diameter of 8 is formed integrally with the fixed hood 90 from plastic.

An inclined surface 120 is formed on the front side of the buffer support portion 119.

The buffer body 116 holds the fixed hood 90 and inserts the part of the buffer body with the protrusion 117 into the hole 118.
The shock absorber 116 is attached to the shock absorber support portion 119 of the fixed hood 90 by inserting the shock absorber 116 into the shock absorber support portion 119 of the fixed hood 90 and gluing it with an adhesive.

- An inclined portion 121 is formed at the rear lower end portion of the ten-cho moving hood 91.

When the movable hood 91 is closed, the inclined portion 121 of the movable hood 91 comes into contact with the protrusion 117 of the buffer body 116.

In this way, since the movable hood 91 is stopped by the buffer body 116, collision noise is reduced, and the movable hood 91 is also protected.

Next, we will discuss how to use this stand hair dryer.

First, the movable hood 91 is opened, the head is inserted into the hood 4B, and then the movable hood 91 is closed.

Next, when the motor 49 and heater wire 55 are turned on,
Air sucked from the external ventilation port 60 by the fan 500 rotations flows toward the fan 50 through the ventilation port 51 and the ventilation hole 53, and flows from the fan 50 into the hood portion 48 through the guard plate 57.

And it dries the hair.

Note that the air passing through the ventilation hole 53 is heated by the heater wire 55.

In the present invention, the support column is greatly curved and the large side of the head insertion section is supported at the upper end of the support column so as to be able to rise and fall freely, so that the lower part of the support column approaches the center of gravity of the head insertion section.

This increases stability and allows for easier elevation adjustment.
