The present invention has been made by focusing on such conventional technology, and an object of the present invention is to provide a sun visor device for an automobile that can automatically put the sun visor body into a use state without using electrical means such as motor drive. It is something to do.

Means for Solving the Problems> In order to achieve the above object, a sun visor for an automobile according to the present invention includes a holder that supports a sun visor body so as to be able to rotate at least forwardly, and a storage space for the long visor body. A case body having a rail portion that forms partitions and engages with which the holding body can slide forward and backward, and an attachment that moves the holding body toward the front end of the rail portion and causes the entire sun visor body to protrude forward from the storage space. The locking means is provided with a biasing means and a locking means capable of restraining and releasing the holder positioned at the rear end of the rail portion against the biasing means.

<Operation> When using the sun visor body, the occupant only needs to release the restraint of the holding body by the locking means with one touch. Then, the sun visor body will be free, so
Due to the action of the biasing means, the holding body moves forward together with the sun visor body and projects forward from the storage space. In this state, the sun visor body is already ready for use, but the occupant can also freely adjust the sun visor body to the optimum angle by freely tilting the sun visor body forward and rotating it with his or her own hands. After use, the sun visor body and the holder can be restrained within the storage space by the locking means simply by pushing the sun visor body into the storage space, and the storage state can be maintained as is.

Embodiment A preferred embodiment of the present invention will be described below with reference to FIGS. 1 to 6. 2 is the sun visor main body, and rotating shafts 2.3 are protruded from the rear portions of the left and right sides, respectively. This 2
Of the two rotating shafts 2.3, the left rotating shaft 2
is integrated with the sun visor body 1, but the right rotation shaft 3 is a separate part with one end 4 rotatably inserted into the sun visor body 1, and the other end 5 side is bent once toward the rear. It then curves further upwards.

Reference numeral 6 denotes a holding body, which has a horizontal plate 7 along the rear end of the sun visor body l, and side parts 8.9 extending forward (direction F in the figure) on both sides of the horizontal plate 7. , this side part 8
．． A pair of front and rear protrusions 10 and 11 are provided on the upper part of the body 9, respectively. Also, the left side portion 8 of this holding body 6
An elastic receiving part 12 is formed at the front end of the sun visor body 1, and the left rotation shaft 2 of the sun visor body 1 is rotatably fitted into the elastic receiving part 12. Further, the other end portion 5 of the right rotation shaft 3 is rotatably inserted and supported in the right side portion 9. A horizontal pin 13.14 protruding in the left-right direction is formed on each projection io, ti provided above each side portion 8.9. Furthermore, the holding body 6
A long hole 17 is formed in the horizontal plate 7 to slidably receive a tip pin 16 of an arm (biasing means) 15 to be described later, and a lock part to be described later is formed in the rear part of the horizontal plate 7. (
A hook 20 that can be freely engaged with the claw 19 of the locking means 18 is formed.

Reference numeral 21 denotes a case body, and this case body 21, together with the roof lining 22, defines a storage space S for storing the sun visor body l.

This case body 21 has a recessed rail portion 23 extending in the front and rear directions on the left and right sides, and the horizontal pins 13 and 14 of the holding body 6 are inserted into elongated holes 24 formed in the side surfaces of the rail portion 23.
are engaged so that they can slide forward and backward.

A lock portion 18 is provided at the rear portion of the case body 21. This lock portion 18 is vertically rotatable around a hinge 25 formed on the case body 21. This lock portion 18 is always urged downward by a spring 26, and has a claw 19 at its tip that engages with the hook 20 described above. Further, a bushing button 27 is formed near the hinge 25 of this locking portion 18, and this bushing button 27 is exposed from a collar 22a provided on the roof lining 22.
When the occupant pushes against the spring 26, the mold 19 moves upward and the engagement between the pawl 19 and the hook 20 can be released.

A protrusion 28 is formed on the case body 21, and the proximal end 30 of the arm 15, which is biased to rotate in the A direction by a spring 29, is supported by the protrusion 28.

Next, the operation will be explained.

In the stored state of the sun visor body 1 (see FIGS. 1 and 4), the sun visor body 1 is stored in the storage space S in a substantially horizontal state, and the holder 6 is located at the rearmost end of the rail portion 23. ing. Further, the hook 20 of the holding body 6 and the pawl 19 of the lock portion 18 are engaged with each other by the biasing force of the spring 26.

When using the sun visor body 1 (see FIGS. 2 and 5), the occupant presses the button 27 of the locking portion 18. Then, the lock portion 18 moves upward against the spring 26, and the engagement between the hook 20 and the pawl 19 is released.

An arm 15 is inserted into the elongated hole 17 formed in the horizontal plate 7 of the holder 6.
Since the tip pin 16 of the arm 15 is engaged with the arm 15 by the restoring force of the spring 29, the tip pin 16 moves within the elongated hole 17 and holds the holder 6 along with the sun visor body l. It is moved forward F along the rail portion 23. When the horizontal pins 13 and 14 of the holder 6 have completely moved to the front end of the elongated hole 24 formed in the rail portion 23, the entire sun visor body 1 is moved from the storage space S to the front window through the opening 22b of the roof lining 22. Projects into the vehicle interior R near panel G. When the sun visor body 1 protrudes forward from the storage space S in this way, the sun visor body 1 is already in use. You can adjust the angle by moving it forward. At this time,
Since a certain sliding force is applied between the rotating shaft 2 and the elastic receiving part 12, and between the rotating shaft 3 and the sun visor body 1, the sun visor body 1 cannot be rotated even if it is tilted. It is positioned at the same angle. Furthermore, depending on the direction of incidence of sunlight, the left rotating shaft 2 of the sun visor body 1 may be separated from the elastic receiving portion 12 of the holder 6, and the sun visor body 1 may be supported only by the other right rotating shaft 3. By doing this, the sun visor main body l can be rotated around the rotation shaft 3 on the right side, so that it is not only exposed to sunlight from the front (front window panel G) but also from the side (for example, the side window). It can also reliably block sunlight.

When storing the sun visor body l after use,
After the rotating shaft 2 of the detached sun visor main body l is fitted again into the elastic receiving part 12 of the holder 6, the sun visor main body l is pushed into the storage space S. When the holder 6 of the sun visor body 1 reaches the rearmost end of the rail section 23, the holder 6
Since the hook 20 engages with the pawl 19 of the lock part 18,
The sun visor main body l is in a state of being restrained and stored in the storage space S by their engagement.

<Effects of the Invention> The automobile sun visor device according to the present invention has the content described above, and allows the occupant to release the restraint of the holding body by the locking means with a single touch, without using electrical means. Just by doing this, you can automatically obtain the usage status of the sun visor body.

Therefore, compared to the conventional method that uses motor drive or other electrical means, it does not require complicated wiring or structure, and is advantageous in terms of weight, cost, and space.
