Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a retractable headlamp that is attached to and used in vehicles such as automobiles and motorcycles.

[Prior art]

Conventionally, as this type of retractable headlamp, one having the structure shown in FIGS. 7 and 8 is known. In this known retractable headlamp, a lamp cover 2 is rotatably attached to an upright wall 1a of a vehicle body mounting angle 1 via a shaft 3, and a headlamp 4 is disposed within the lamp cover 2. Furthermore, one end of a drive lever 5 is attached to the outside of the lamp cover 2 so as to be movable along its thrust axis. The other end of the drive lever 5 is configured to be moved back and forth by a motor, and when the drive lever is pushed forward, the headlamp falls forward and becomes unable to illuminate.
When the drive lever is pulled back, the headlamp rises and becomes ready for illumination.

[Problem that the invention attempts to solve]

The retractable headlamp having the above structure has a problem in that it is driven by a motor and is therefore expensive. Furthermore, since the headlamp is supported by the drive lever at the position where the motor is stopped, there is also the problem that the undulating position of the headlamp is not constant and is not stable.

[Means for solving problems]

As a specific means for solving the above-mentioned problems, the present invention provides a structure in which a holder having a substantially U-shaped planar shape and to which a headlamp is attached is rotatably attached to the inside of a housing formed in a substantially U-shaped planar shape via a shaft. The holder is biased in one direction by a spring wound around the shaft, and an arc-shaped guide slot having a predetermined length and circular holes at both ends is provided on one side of the holder. A stopper biased by a coil spring is disposed on one side of the housing corresponding to the guide slot, a knob is provided at one end of the stopper, and a head is formed at the other end. The retractable headlamp is characterized in that the stopper engages with the guide slot to restrict rotation of the holder, and the head fits into the circular hole to maintain the set position. By manually operating the knob, the headlamp can be easily and precisely set in the use and non-use positions.

〔Example〕

Next, the present invention will be explained in more detail with reference to the illustrated embodiment. Reference numeral 11 denotes a housing, and the housing has a substantially U-shape when viewed from above. Inside this housing 11 is a holder 12 having approximately the same shape.
is biased in one direction via the shaft 13 and is rotatably attached. The shaft 13
Both ends of the shaft are pivoted to the housing 11, and the holder 12 is rotatably supported near both ends of the shaft. And the shaft 1
A spring 14 is wound around 3, one end of which is engaged with the holder 12, and the other end of which is engaged with the housing 11.
Due to this action, the holder 12 is always urged upwardly.

A headlamp 15 is attached to the holder 12, and as shown in FIG. 4, a guide slot 16 is provided on one side of the holder to restrict rotation of the holder itself. The entire guide slot is formed in an arc shape, and both ends thereof are formed into slightly larger circular holes 16a and 16b. Such a guide slot 16 can be provided directly in the holder 12, but due to circumstances such as press working, in order to avoid deformation of the guide slot, for example, a relatively large diameter oval hole 12a is provided in the holder 12. Then, a plate member 12b having a guide slot 16 formed separately facing this oval hole may be attached by means such as spot welding. In any case, it is necessary that the guide slot 16 be formed with relatively accurate dimensions.

In order to prevent the holder 12 from lifting upward from a certain position, the housing 11 is provided with a tongue portion 11a for a stopper, and a bracket 17 is provided on one side of the housing, and a stopper shaft 18 is disposed through the bracket. A head 18a with a large diameter is formed at one end of the stopper shaft, and a knob 19 is attached to the other end.The stopper shaft 18 is supported by a coil spring 20.
It is configured to always be pushed outward. The stopper shaft 18 is connected to the holder 12.
is provided in the guide slot 16, and its head 1
8a is adapted to fit into either circular hole 16a or 16b at both ends. In addition, 21 in the figure
22 is a body, and 23 is a lamp cover attached to the holder 12.

[Explanation of operation]

Next, to explain the operation, when the headlamp is used, the headlamp is raised to the position shown in FIG.
1a comes into contact with the head 1 of the stopper 18.
8a is a circular hole 16 at one end of the guide slot 16;
a and is held in a fixed state (see Fig. 5). When storing the headlamp from this position to a position where it is not in use, when the knob 19 is pushed in with a finger, the head 18a of the stopper 18 comes out of the circular hole 16a, releasing the fixed state (see FIG. 6).
In this state, the stopper 18 is positioned in the guide slot 16, so when the headlamp is pressed from above, the holder 12 rotates around the shaft 13, as shown by the imaginary line in FIG.
As soon as the stopper 18 is fitted into the vehicle body, the head 18a of the stopper 18 is fitted into the circular hole 16b to hold the headlamp in its housed position.
Also, when using a headlamp, turn knob 19.
When pushed in, the head 18a of the stopper 18 comes out of the circular hole 16b, and at the same time the spring 14
Since the holder 12 is urged upward by the action of the holder 12, the headlamp immediately jumps upward together with the holder, the holder 12 comes into contact with the stopper tongue 11a, and the head 18a of the stopper 18 fits into the circular hole 16a. It fits in and stays upright. In short, when you close the headlamp, press the knob 19 and also push the headlamp,
When in use, simply press the knob 19 to release the spring 14.
By this action, it automatically rises and is held and fixed in the position of use.

[Effect of idea]

As explained above, in the retractable headlamp according to the present invention, a holder having a substantially U-shaped planar shape and to which the headlamp is attached is rotatably disposed inside a housing formed in a substantially U-shaped planar shape via a shaft. The holder is biased in one direction by a spring wound around the shaft, and an arc-shaped guide groove having a predetermined length and circular holes at both ends is provided on one side of the holder. a stopper biased by a coil spring is disposed on one side of the housing corresponding to the guide slot, a knob is provided at one end of the stopper, and a head is formed at the other end;
The stopper engages with the guide slot to restrict rotation of the holder, and the head fits into the circular hole to hold the set position, so that the knob can be operated by hand, When in use, simply pushing the knob causes the spring to immediately and accurately raise the stopper to the set use position, and the head of the stopper fits into the circular hole to hold the stopper in a stable state, which is an excellent effect.

Furthermore, regarding the operation, the headlamp can be stored and rotated to the use position with a simple manual operation, and since no power from a motor or the like is used, the cost is reduced, which is an excellent effect.
