Description

[Detailed Description of the Invention] This invention relates to a bicycle buzzer equipped with a device for projecting an image from a projection device installed in a screen panel attached to a window on the peripheral surface of the outer shell.

This invention was made for the purpose of providing a bicycle buzzer equipped with an image projection device in order to diversify play, since cut-and-paste bicycles are used as exercise equipment and recreational equipment.

A screen panel is installed on the outer surface of the buzzer, and an image is projected using a projection device built into the screen by pressing a dedicated switch button.If the switch button is pressed while driving and you are fascinated by the moving image, Bundle handling becomes careless and dangerous.

In this invention, a cover plate is provided which is biased so as to always shield the surface of the screen panel, and the drawer knob of the cover plate and the switch button of the projection device are arranged with a distance between them. The screen was designed so that it was impossible to operate both with one hand at the same time, and the image on the screen could only be displayed when the cover plate was opened with one hand and the switch button was pressed with the other hand. .

This invention will be explained below with reference to drawings as examples.
1 is an outer shell in which a sound generator 2, a warning light 3, and a projection device 4 are installed.

The outer shape is formed into the head of an anthropomorphic doll, a window 5 is provided on the outer peripheral back surface, and a translucent milky white screen board 6 is attached.

On the outer surface 7 of the screen panel 6, there is a cover plate 8 which is integrally connected to the outer shell 1 at the upper edge of the window 5 of the outer shell 1 and is connected by a hinge 1a formed to always bend inward. It is provided so that the screen panel 6 can be shielded.

A drawer knob 9 whose base is curved into a U-shape is integrally connected to the center of the lower edge of the lid plate 8, and the base of the knob 90 fits into the engagement groove 10 of the screen board so that it can be latched. .

Next, in the projection device 4, the original image drum 12 with the projection film 11 wrapped around the outer periphery is supported on a bearing stand 14 provided at the rear of the support frame 13 attached to the outer shell 1, and the original image drum 12 is mounted on the support frame 13. The lower periphery of the original image drum 12 is connected to a transmission shaft 16 which is rotated by a motor 15 supported by the main body, and is rotated about a support shaft 17 .

Inside the original drum 12, a light bulb 18 is supported approximately at the center of a reflector 19 that is integrally provided behind a bearing stand 14 on the rear upper surface of the support frame 13, and its light source illuminates the original drum 12 on the screen board 6. It projects images.

Reference numeral 20 denotes a switch button, which is arranged at the lower back of the outer shell with a distance from the drawer knob 9 of the cover plate that is difficult to reach with an average cut and paste finger when the cover plate is unfolded. Switch box 2 suspended from support frame 13 inside the outer shell
When the switch button 20 is pressed, the electric circuit is closed and the motor 15 is operated, and the light bulb 1 is
8 lights up.

23 is a battery case provided integrally with the outer shell 1, and a lid 24 is attached with screws 25, 25.

26 is a fitting for attaching to the bundle 27.

Although not shown, a separate switch is provided for use as a buzzer.

A hinge Ial is provided as a member separate from the outer shell 1, and a spring 28 biases a lid plate 28 which is formed separately from the outer shell 1 and has a bottom shape.

This idea is as described above, so when only the switch button 20 is pressed, the internal projection device 4 is activated and an image is projected on the screen panel 6, but since it is shielded by the cover plate 8, it cannot be seen from the outside. I can't see it.

Next, as described above, press the switch button with one hand and pull out the cover plate 8 with the other hand and pull the knob 9 to release the latch, and then as shown in FIG. When the screen panel 7 is opened, the image on the projection drum 4 is projected onto the screen panel 7, which satisfies the needs of cutting and pasting.

Although not shown, the sound generator 2 and the warning light 3 can be activated continuously or intermittently at this time to serve as background sound for the video.

When a hand is released from the cover plate 8, the cover plate 8 automatically rotates around the hinge 1a and is connected to the screen board 6 to shield the board surface.

The image is then hidden under the cover plate 8 and cannot be viewed.

Opening the cover plate 8 with the hand that is pressing the switch button 20 is not possible because there is a gap in the installation position and the cover plate 8 itself is energized, so be sure to use both hands. You can only see the image projected on the buzzer.

Therefore, there is no need to worry about the image being distorted while driving.
Expanding the function of the buzzer as a play toy while ensuring safety,
This contributes to the diversification of bicycle play.
