Abstract

PURPOSE:To display the speed and the direction in a simple constitution by forming a lamp group on the right and left of the front and selectively operating the direction indication of lighting lamps sequentially from one direction and the speed indication of lighting lamps of a number corresponding to the output of a dynamo pressed to a wheel. CONSTITUTION:Indicator lamps L1-L7, R1-R7 are disposed on the right and left of the front of a bicycle, respectively. When a direction indicator control circuit not shown is selectively operated, the lamps for indicated direction are lighted and extinguished sequentially from the first lamp L1 or R1 to display the direction. When a speed indicator control circuit not shown is selectively operated, the output voltage of a dynamo pressed to a wheel is detected, a speed switching element not shown is operated, and the indicator lamps of a number corresponding to the speed are lighted to display the speed. By this arrangement, the direction and the speed can be displayed with a small number of parts.

Description

[Detailed description of the invention] b) Industrial application field The present invention relates to a display device used on a bicycle.

Conventional technology In the past, for example, a light bulb or an LED was used as a display device, and the display device was used as a speed indicator light, direction indicator light, or the like.

That is, in the prior art, a speed indicator light and a direction indicator light had to be provided separately, which resulted in an increase in the number of parts and an increase in the size of the mounting structure for the bicycle.

1/C Problems to be Solved by the Invention The present invention provides a bicycle display device that can display speed and direction while greatly reducing the number of parts.

2) Means for Solving the Problem Direction control (1) for sequentially lighting up the lamps of the indicator lamp group and one of the left and right indicator lamp groups.
) a speed display control means for detecting an output voltage corresponding to the speed of a dynamo that is in pressure contact with a wheel of the bicycle body, and lighting up a number of lamps from the left and right display lamp groups according to the output voltage; and the direction indicator. and a selection means for arbitrarily selecting the operation of the speed display control means or the speed display control means.

(E) Function Since the present invention has such a configuration, the same indicator lamp can serve both as a direction indication and a speed indication.

(to) Example +13tl) is the front left and right guard mounting brackets (2) of the bicycle body.
) is a pair of headlights installed using the (3) is the front wheel. (4 bar 4) is a lamp storage case attached to a carrier (51) fixed to the bicycle body so as to be located on the front left and right sides of the bicycle body. 7th indicator lamp (Ll) (Ll) (L3) (L4) (L5) (L6)
(Ll) are arranged in a row on the left pump group B, and the same multiple display lamps (RIXR2XR3XR4XR5XR6X
R7) are arranged in the same lζ arrangement as the right lamp group (2).

Next, to explain the electric circuit diagram, the first left indicator lamp to the seventh left indicator lamp (Ll) (Ll) (L3) of the left lamp group.
(L4) (L5) (L6) (Ll) are connected in parallel, respectively, and the left switching element (SL
) are connected to each of Jζ. 1st right indicator lamp to 7th right indicator lamp (R1) (R2) (R3XR
4XR5) (R6XR7) are connected in parallel, and a right switching element (SR) consisting of a transistor is connected.

In addition, the first left indicator lamp (first right indicator lamp (R1)
) is connected to the parallel circuit of the first direction switching element aα and the seventh speed switching element (11). Similarly, the parallel circuit of the second left indicator lamp (Ll) and the second right indicator lamp (R2) is connected to the parallel circuit of the second switching element decoy for this direction and the sixth switching element for speed. Similarly, the third switching element for direction, αη, α9, (company), ■
Connect with. ■ is a battery that serves as a power source.

(1) is a control circuit for direction indication, and when power is input,
Outputs (Ql) (Q2) (Q3) (Q4) are sequentially applied from the first switching element for direction to the seventh switching element for direction @ to operate (ON) each of them.
) (Q5) (Q6) (Q7), and are turned on and off in order.

(A) is a speed display control circuit that detects the output voltage generated in accordance with the rotational speed of the wheel from a dynamo (company) installed on the bicycle that presses against the outer side of the wheel, and responds accordingly to the output voltage. output from the first speed switching element (SIX) to the seventh speed switching element (SIX).
S2XS3XS4XS5XS6XS7). In this case, unlike the above-mentioned direction switching element, once the speed switching element is operated and turned on, the speed control circuit remains output until it returns to its initial state.

Further, as shown in Table 1 below, for example, if the rotation detection speed of Dynamo Co., Ltd. is 15 km/h, the output voltage at that time is 1. Ov, and this 1. The speed display control circuit detects Ov, and as a result, the speed display first switching element -
It is output (Sl) to operate the . Also, when the rotation detection speed reaches 6.0 m/h on the left, the output voltage becomes 2.2V, and as a result [1f! ] The speed display control circuit (is output (Sl) from 4B and operates the second speed switching element ell. At this time, the first speed switching element
The operation (ON) is also continued.

The gloss is a manually operated selection means installed on the handlebar of the bicycle, and each one is linked and switched in the same way.
It has 1 switching contact pieces (50a x 5ob x 50c). The first switching contact (50a) has a left contact port connected to the left switching element (SL), a right contact (61) connected to the right switching element (SR), and both switching elements (SL). Intermediate point (@
Switch to connect.

The at 2 switching contact (50b) is switched and connected to the neutral contact (@), the M1 contact (goods) connected to the direction indication control circuit (2), and the second contact can.

The third switching contact piece (50c) is switched and connected to the third contact point 2 connected to the dynamo 0υ and two neutral contacts (sources).

To explain the operation of this configuration, first, in order to make a left turn, when the selection means mark is operated to connect the first switching contact (50a) to the left contact field, the second switching contact (sob) connects to the first contact (50a).
In this case, the third switching contacts (SaC) are connected to the neutral contacts respectively, so that the left switching element (SL) operates, and the switching elements sequentially switch from the first direction switching element α■ to the seventh direction switching element α■. As a result, the first left indicator lamp (Ll) lights up, and then the seventh left indicator lamp (Ll) lights up, and the light source of the left lamp group flows from the inside to the outside. It is something that moves.

When you want to know the running speed, connect the first switching contact (50a) of the selection means (3) to the intermediate contact -, the second switching contact (sob) to the neutral contact -, and the third switching contact (50c) to the neutral contact -. ) are connected to the third contact fields, respectively. By doing so, both the left switching element (SL) and the right switching element (SR) operate, and if the bicycle speed at that time is 9 km/h, the speed display control circuit (output from the grip (SI X52XS3) is generated, and the first switching element for speed, the second switching element (21+), and the third switching element α are operated.

As a result, the seventh left indicator lamp (Ll), the sixth left indicator lamp (R6), the fifth left indicator lamp (R5), and the seventh
The right indicator lamp (R7), the 6th right indicator lamp (R6), and the 5th right indicator lamp (R5) are all lit at once, and the user can determine the current driving speed from the number of lit lamps. This allows you to know the standard.

(G) Effects of the Invention Since the present invention has such a configuration, the same indicator lamp can be used to indicate direction and speed (estimate), resulting in a significant reduction in parts and simplification of the mechanism. It is something that can be done.
