Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a sun visor locking device for locking a sun visor used as a sunshade on a front window of an automobile in a stored state.

[Prior Art] As a conventional device, there is one shown in FIG. 7, for example (see Japanese Utility Model Application No. 61-70126). That is, the sun visor 101 is configured to be stored in the ceiling of the vehicle interior as shown by the solid line in FIG. 7 by the frictional force in the rotation shaft 103 of the sun visor 101. The sun visor 101 is removed from the solid line state 101A shown in the figure by pushing the movable member 105 firmly through the sun visor 101. That is, the movable member 105 is unlocked by the pressure from the sun visor 101, and the spring 1
Due to the biasing force 07, the movable member protrudes as shown by the chain line in the figure, thereby pushing out the sun visor 101. And like this sun visor 10
1 is pushed out, the sun visor 101 can be rotated by hooking the sun visor 101 with a finger. Further, to store the sun visor 101 as shown by the solid line in FIG. 7, rotate the sun visor 101 as shown by the solid line in FIG. 7 and lightly press the movable member 105, and the movable member 105 will be locked in that position. At the same time, the sun visor 101 is held by the frictional force on the rotating shaft 103, and can maintain the stored state.

However, in such a structure, the sun visor 1
01 is held in the stored state by the frictional force on the rotating shaft 103.
There is a risk that the sun visor 101 may flap due to the vibration of the vehicle. This flapping of the sun visor 101 can be prevented by increasing the frictional force on the rotating shaft 103, but this increases the operating force of the sun visor 101, resulting in a problem of poor operability. Further, the sun visor 101 has a soft surface, and since the soft surface of the sun visor 101 is extruded, the extrusion of the sun visor 101 may be insufficient, and subsequent operations may become troublesome.

[Problems to be solved by the invention] As described above, when trying to prevent the sun visor from flapping due to the vibrations of the vehicle when the vehicle is running, the conventional device requires a large amount of operating force to operate the sun visor.
There was a risk that the extrusion of the sun visor would be insufficient.

Therefore, this invention provides a sun visor locking device which can reduce the operating force of the sun visor, securely lock the sun visor in the stored state, and facilitate the operation of the sun visor after the lock is released.

[Means for Solving the Problems] In order to solve the above problems, this invention includes a case with one end open provided on either the ceiling of the vehicle interior or the sun visor, and a case that can be freely entered and exited from the case. An inserted button with one end open, a spring that biases the button in the protruding direction, a hook provided in the case that passes through the button and faces the open end side of the button, and between the button and the hook. cam means provided for deflecting the hook in the engaging direction when the button enters into the case; and locking means for locking the button in the engaged state when the button enters the case with the first action and releasing the lock when the button enters the case with the second action. and an engagement piece that can be engaged with a hook that is provided on either the other side of the vehicle interior ceiling or the sun visor and is bent in the engagement direction.

[Function] When the sun visor is rotated toward the ceiling of the vehicle interior and the button is made to perform the first approach motion with respect to the case,
The button is locked by the advancing motion, and the hook is deflected in the engagement direction by the cam means upon this advancing motion. Then, the engaging piece engages with the hook bent in the engaging direction, and the sun visor is locked and held in the housed state in the ceiling of the vehicle interior. Next, when the sun visor is pressed against the ceiling of the vehicle interior and the button is caused to perform a second advancing operation, the lock by the locking means is released and the button is projected by the spring. At the same time, the hook restores its deflection to its original position and disengages the engagement piece.
The sun visor is no longer locked in the retracted state. Therefore, it can be easily rotated from now on.

[Example] Examples of this invention will be described below.

and a protrusion 39 formed on the hook 31 side and capable of coming into contact with the inclined surface 37.

Further, a locking means 41 is provided between the case 19 and the button 27. This locking means 41 locks the button entry state by the first entry action of the button 27, and releases the lock by the second entry action, and the heart cam 4 shown in FIG.
3 and a pin 45. The heart cam 43 is formed on the side surface of the button 27, and is constituted by a heart-shaped cam groove 43a. The cam groove 43a includes a top portion 43b, a first protrusion 43c, a second protrusion 43d, a lock portion 43e, and a peak portion 43f. The pin 45 is fixed to the case 19, and its tip faces into the case 19 through a window 47 formed in the case 19, and engages with the cam groove 43a of the heart cam 43.

On the other hand, the sun visor 1 is constructed by covering a shape-retaining base material 45 with a pad 47 and covering the surface of the pad 47 with a skin 49. The sun visor 1 has a pad 47 and a part of the skin 49 cut out at a location facing the hook 31 on the side of the ceiling 7 of the vehicle interior, and a cylindrical fixing case 51 fixed to the shape-retaining base material 45. is buried.

Removal prevention is in place. A flange portion 55a is provided at one end of the escutcheon 55 and is configured to cover an end portion of the fixed case 51. The end portion 49a of the skin 49 of the sun visor 1 around the escutcheon 55 is the flange portion 55 of the escutcheon 55.
a and the end of the fixed case 51, and its terminal processing is performed. Further, an engagement piece 59 that can be engaged with the hook 31 when the hook 31 is bent in the engagement direction is integrally provided on the inner peripheral side of one end of the escutcheon 55 in a protruding manner.

Next, the operation of the above embodiment will be described with reference to the schematic diagram of FIG.

The sun visor 1 is stored in the storage recess 17 in the ceiling 7 of the vehicle interior.
To lock the sun visor 1 in the stored state, first rotate the sun visor 1 toward the ceiling 7 of the vehicle interior, and place the escutcheon 55 on the sun visor 1 opposite one end of the button 27 as shown in FIG. 5a. When the sun visor 1 is further pressed against the ceiling 7 of the vehicle interior, the button 27 is lightly pressed by the escutcheon 55 against the biasing force of the spring 29 as a first advancing motion, and enters into the case 19. This first movement of the button 27 causes the inclined surface 37 of the cam means 35 to press against the protrusion 39, and the hook 3
1 is bent in the engagement direction and engages with the engagement piece 59 of the escutcheon 55. At this time, the locking means 41
Due to the first movement of the button 27, the tip of the pin 45 moves relatively from the top 43b of the cam groove 43a, climbs over the first protrusion 43c, and engages with the lock portion 43e by its own elasticity. Therefore, the engaging piece 59 on the sun visor 1 side is connected to the hook 3 on the vehicle interior ceiling 7 side.
1, the movement of the button 27 is locked by the locking means 41, and the sun visor 1 is held in a locked state on the vehicle interior ceiling 7 via the locking device 9. Further, in this locked state, the engaging piece 59 on the sun visor 1 side engages with the hook 31, and its movement is also restricted by one end of the button 27. Therefore, sun visor 1
is reliably held in a locked state by the locking device 9, and can prevent flapping due to vibrations caused by the running of the vehicle. Moreover, since such a locking operation of the sun visor 1 is performed by pressing the button 27, which is a solid object, using the escutcheon 55, which is a solid object, it can be performed reliably.

To unlock the sun visor 1, press the sun visor 1 strongly from the state shown in Fig. 5b and press the button 27.
strongly press against the biasing force of the spring 29,
A second approach operation is performed. Due to this second advancing operation of the button 27, the tip of the pin 45 is guided from the lock portion 43e to the crest 43f, and is guided to the second protrusion 4.
3d side, and the button 27 is pushed out as it is by the bias of the spring 29 at a position where it is removed from the second protrusion 43d. Simultaneously with the protrusion of the button 27, the cam means 35 gradually releases the pressure on the protrusion 39 by the inclined surface 37, and the hook 31 gradually restores its deflection to its original position, releasing the engagement of the escutcheon 55 with the engagement piece 59. do. and hook 3
1 is disengaged from the engagement piece 59, the button 27 further protrudes due to the urging force of the spring 29, presses the escutcheon 55 of the sun visor 1, and moves the sun visor 1 toward the ceiling of the vehicle interior as shown in FIG. Push it out from the storage recess 17 of the section 7. Therefore, the sun visor 1 can freely rotate downward within a predetermined range. At this time, the button 27 is prevented from protruding by moving the pin 45 of the locking means 41 from the locking portion 43e to the top portion 43b. On the other hand, the occupant can place his or her fingers on the sun visor 1 that has been pushed out as described above.
The sun visor 1 can be easily rotated around the rotation shaft 5, and the sun visor 1 can be set at any position by the frictional force on the rotation shaft 5.

Since the sun visor 1 is thus held in a locked state by the locking device 9 on the ceiling 7 of the vehicle interior, the frictional force on the rotation shaft 5 can be reduced, and the operability of the sun visor 1 is significantly improved. be able to. Further, by releasing the lock by the locking device 9, the holding of the sun visor 1 can be released. For example, by freely rotating the sun visor 1 downward on the side of the ceiling part 7 of the vehicle interior, the lock can be surely released. Subsequent operations will be easier. Furthermore, when the sun visor 1 is pressed, the first button 27 is pressed.
When performing the second approach operation, the button 27 is pressed via the escutcheon 55, so that the operation can be performed reliably.

Figure 6 shows another embodiment of this invention.
The escutcheon 55 is provided in a case 63 of a vanity mirror 61. In this case, there is no need to provide a fixing case or the like for fixing the escutcheon 55, and costs can be reduced.

Note that this invention is not limited to the above embodiments. For example, the case 19, button 27, etc. may be provided on the sun visor 1 side, and the escutcheon 55, etc. may be provided on the vehicle interior ceiling portion 7 side.

[Effects of the invention] As is clear from the above, according to the structure of this invention, the sun visor is held in a locked state on the ceiling of the vehicle interior by the engagement of the hook and the engagement piece, so that the frictional force of the sun visor rotation shaft is reduced. Even if it is made smaller and the operating force is reduced, it is possible to suppress the flapping of the sun visor in the stored state. In addition, since the lock is securely secured by the hook and engagement piece, the sun visor can be moved away from the ceiling of the vehicle interior by freely rotating downward within a predetermined range after the lock is released, making the operation after the lock is released extremely easy. It becomes easier.
