BIKE SADDLE WITH ILLUMINATION-CONTROLLED LIGHTS

Abstract

An alarm light assembly for a bike saddle includes at least one lighting unit, a light sensor unit, an electric energy unit, a control unit, and a threshold-signal storage unit. The light sensor unit detects surrounding brightness and generates a surrounding brightness signal. The control unit receives and compares the surrounding brightness signal with a threshold signal such that when the surrounding brightness signal is less than the threshold signal, a driving signal is generated to drive the lighting unit to generate alarm lighting.

Claims

1. A bike saddle provided with an alarm light assembly mounted on a circumferential rim of the saddle, the alarm light assembly comprising: at least one lighting unit mounted on a circuit carrier board; an electric energy unit connected to the alarm light assembly to supply electric energy to the alarm light assembly; a light sensor unit operable to detect a surrounding brightness and generate a surrounding brightness signal; a control unit connected to the lighting unit and the light sensor unit to receive the surrounding brightness signal generated by the light sensor unit; and a threshold-signal storage unit connected to the control unit to supply a threshold signal to the control unit; wherein the control unit compares the surrounding brightness signal generated by the light sensor unit with the threshold signal such that when the surrounding brightness signal is less than the threshold signal, a driving signal is generated to drive the lighting unit to generate an alarm lighting.

2. The bike saddle as claimed in claim 1, wherein the alarm light assembly is mounted to the circumferential rim of the saddle and a protective plate is provided to cover the alarm light assembly.

3. The bike saddle as claimed in claim 1, wherein the alarm light assembly is attached by an adhesive layer to a surface of the circumferential rim of the saddle.

4. The bike saddle as claimed in claim 1, wherein the alarm light assembly comprises an insertion terminal that is insertable into a fitting slot formed in the saddle.

5. The bike saddle as claimed in claim 1, wherein the alarm light assembly is embedded in a recess formed in the circumferential rim of the saddle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] With reference to the drawings and in particular to FIG. 1, a perspective view is given to illustrate a first embodiment of the present invention. As shown in the drawing, a saddle 1 is formed with a circumferential rim 11, and the saddle 1 has a bottom to which a bar 12 is mounted.

[0024] In the design according to the present invention, the circumferential rim 11 of the saddle 1 is provided with an alarm light assembly 2, which is automatically lit on according to a surrounding brightness of a current location when a cycler is riding a bicycle so as to improve cycling safety. The saddle 1 is made of known materials, such as soft foaming materials, polymer materials, leather materials, or waterproof materials. The alarm light assembly 2 can be integrally combined with the structure of the saddle 1 and covered by a protective plate 13.

[0025] Referring additionally to FIG. 2, the alarm light assembly 2 comprises a plurality of lighting units 21 arranged on and distributed along the circumferential rim 11 of the saddle 1 and is mounted to a circuit carrier board 3. An electric energy unit 22 is mounted on the circuit carrier board 3 and connected to the alarm light assembly 21 to supply electric energy to circuit components of the alarm light assembly 2.

[0026] A light sensor unit 23 is mounted on the circuit carrier board 3 or alternatively mounted to a location on the circumferential rim 11 of the saddle 1 or any other sites suitable for detecting surrounding brightness in order to detect a surrounding brightness L and then generate a surrounding brightness signal S1.

[0027] A control unit 24 is connected to the lighting units 21 and the light sensor unit 23 to receive the surrounding brightness signal S1 generated by the light sensor unit 23. A threshold-signal storage unit 25 is connected to the control unit 24 to supply a threshold signal S2 to the control unit 24.

[0028] The control unit 24 compares the surrounding brightness signal S1 generated by the light sensor unit 23 with the threshold signal S2 such that when the surrounding brightness signal S1 is less than the threshold signal S2, a driving signal S3 is generated from the control unit 24 to drive the lighting units 21 to generate alarm lighting.

[0029] Referring to FIG. 3, a perspective view is given to illustrate a second embodiment of the present invention. Most of the components/parts of the instant embodiment are similar to the counterparts of the first embodiment and thus, similar components/parts are designated with the same reference numeral for consistency. In the instant embodiment, the alarm light assembly 2a similarly comprises lighting units 21, an electric energy unit 22, a light sensor unit 23, and a circuit carrier board 3, and the circuit carrier board 3 is attached by means of an adhesive layer 4 to a surface of a circumferential rim 11 of a saddle 1. Thus, a user may mount the alarm light assembly 2a to an ordinary saddle 1 as desired to similarly achieve an alarm function.

[0030] Referring to FIG. 4, a perspective view is given to illustrate a third embodiment of the present invention. In the instant embodiment, an alarm light assembly 2b comprises an insertion terminal 26 extending therefrom for insertion into a fitting slot 14 formed in a circumferential rim 11 of a saddle 1 t to similarly achieve an alarm function.

[0031] Referring to FIG. 5, a perspective view is given to illustrate a fourth embodiment of the present invention. In the instant embodiment, an alarm light assembly 2c is made as a unitary structure in the form of a circular configuration, a rectangular configuration, or other shapes and is embedded in a recess 15 formed in the circumferential rim 11 of the saddle 1 to similarly achieve an alarm function.

[0032] Referring to FIG. 6, a perspective view is given to illustrate a fifth embodiment of the present invention. In the instant embodiment, an alarm light assembly 2d comprises an insertion terminal 26 extending therefrom for insertion into a fitting slot 17 formed in a base 16 of a saddle 1. The fitting slot 17 comprises and is delimited by rails 18a, 18b formed on left and right sides of the base to be opposite to each other so as to similarly achieve an alarm function.

[0033] Referring to FIG. 7, a perspective view is given to illustrate a sixth embodiment of the present invention. In the instant embodiment, an alarm light assembly 2e is coupled, by means of a fastening member 5 (such as a bolt or a buckle), to an extension section 6 extending from a saddle 1 to similarly achieve an alarm function.

[0034] Although the present invention has been described with reference to the preferred embodiments thereof, it is apparent to those skilled in the art that a variety of modifications and changes may be made without departing from the scope of the present invention which is intended to be defined by the appended claims.
