DETAILED DESCRIPTION OF THE INVENTION
With reference to FIGS. 1, 2, 7A and 7B, a safety light in accordance with the present invention is mounted retractably in an open end of a handlebar (A) of a bicycle, provides both a warning and an illumination capability and comprises a housing (10), a retaining clamp (20), a sleeve (30), a lamp assembly (40) and a spring (50).
The housing (10) is mounted in the handlebar (A) of a bicycle and has a tubular body (11), a flange (14) and a guide key (15). The tubular body (11) has a proximal end (13), a distal end (12), and an inner surface. The proximal end (13) is closed and has a mounting hole (131). The mounting hole (131) may be square and is defined through the proximal end (13) of the tubular body (11). The flange (14) is formed on and protrudes radically out from the distal end (12) of the tubular body (11). The guide key (15) is formed on and protrudes in from the inner surface of the tubular body (11).
With further reference to FIGS. 4 and 5, the retaining clamp (20) is mounted securely through the mounting hole (131) in the tubular body (11) and has a casing (21) and a clamp (22). The casing (21) is mounted securely through the mounting hole (131) in the proximal end (13) of the tubular body (11) and has a front end, two sides, two optional transverse lips and two optional protrusions (211). The front end is open. The transverse lips are formed respectively on and protrude respectively from the sides at the front end of the casing (21) and abut the proximal end (13) inside the tubular body (11). The protrusions (211) are formed on and protrude respectively out from the sides of the casing (21) and engage the proximal end of the tubular body (11) outside the tubular body (11). The clamp (22) is a toggled jaw-type clamp, closes on and clamps an object pressed into the clamp and is mounted in and protrudes from the front end of the casing (21).
The sleeve (30) is tubular, may be resilient, is mounted around the tubular body (11), abuts the flange (14) on the tubular body (11) and holds the housing (10) securely in a tubular handlebar (A).
The lamp assembly (40) is mounted retractably in the housing (10) and comprises a lamp housing (41), a retaining post (44), an optional battery set (45) and a light assembly.
The lamp housing (41) is cylindrical and hollow, is mounted retractably in the housing (10) an has an outer surface, an inner surface, an inner end, an outer end, a front, a rear, an optional front shell (411), an optional rear shell (412), at least one lamp hole (4111, 4123), a light assembly chamber (42) and a battery chamber (43). The inner end is open. The outer end is closed. The rear has a guide slot (4121), a mounting slot (4122) and an optional switch hole (4124). With further reference to FIG. 6, the guide slot (4121) is defined longitudinally in the outer surface on the rear of the lamp housing (41) and engages the guide key (15) in the tubular body (11) to keep the lamp housing (41) from rotating in the tubular body (11). The mounting slot (4122) may be L-shaped, is defined longitudinally in the outer surface of the rear of the lamp housing (41) and communicates with the inner end of the lamp housing (41) and the guide slot (4121). The switch hole (4124) is defined through the lamp housing (41) near the outer end of the lamp housing (41). The front shell (411) is semicylindrical and hollow. The rear shell (412) is semicylindrical and hollow and corresponds to and is mounted on the front shell (411) to form the lamp housing (41).
The at least one lamp hole (4111, 4123) may be a front lamp hole (4111), a rear lamp hole (4123) or both and is defined through the lamp housing (41) near the outer end. The front lamp hole (4111) is defined through the front of the lamp housing (41) and has an optional conical flange (4112). The conical flange (4112) is formed around the front lamp hole (4111), protrudes in from the inner surface of the lamp housing (41), may be inclined toward the inner end of the lamp housing (41) and may have a silver coating to reflect light. The rear lamp hole (4123) is defined through the rear of the lamp housing (41) near the outer end.
The light assembly chamber (42) is defined in the lamp housing (41) adjacent to the outer end of the lamp housing (41).
The battery chamber (43) is defined in the lamp housing (41) adjacent to the light assembly chamber (42) and communicates with the light assembly chamber (42).
With further reference to FIG. 3, the retaining post (44) is formed on and protrudes longitudinally from the inner end of the lamp housing (41), selectively engages and is held by the clamp (22) to hold the lamp housing (41) in the tubular body (11) and has a distal end and an enlarged head (441). The enlarged head (441) is formed on the distal end of the retaining post (44) and corresponds to and is held selectively by the clamp (22).
The battery set (45) comprises multiple batteries and is mounted in the battery chamber (43) in the lamp housing (41).
The light assembly is mounted in the light assembly chamber (43) in the lamp housing (41) and comprises a circuit board (46), at least one lamp (462, 463) and an optional pushbutton switch (461), contact switch or slide switch. The circuit board (46) is mounted in the light assembly chamber (42) in the lamp housing (41) and is connected electrically to the battery set (45). The at least one lamp (462, 463) is mounted on the circuit board (46), corresponds respectively to the at least one lamp hole (4111, 4123) and may be a warning lamp (462), an illumination lamp (463) or both. The warning lamp (462) is colored, may be red or yellow, may be an LED, extends through the rear lamp hole (4123) in the lamp housing (41) and warns overtaking traffic of the presence of the bicycle. The illumination lamp (463) is a white light, may be an LED, extends through the front lamp hole (4111) in the lamp housing (41) and provides illumination for a person riding the bicycle. The pushbutton switch (461) is mounted on the circuit board (46), extends through the switch hole (4124) in the rear shell (412) and turns the illumination and warning lamps (462, 463) on and off. The contact switch is connected electrically to the circuit board (46), is mounted on the outer surface of the lamp housing (41) and turns the illumination and warning lamps (462, 463) on and off. The slide switch is connected electrically to the circuit board (46), is mounted between the housing (10) and the lamp housing (41) and turns the illumination and warning lamps (462, 463) on and off.
The spring (50) is mounted in the housing (10) around the retaining post (44) between the lamp assembly (40) and the retaining clamp (20) and pushes the outer end of the lamp housing (41) out of the tubular body (11) to expose the illumination lamp (463), the warning lamp (462) and the pushbutton switch (461).
The safety light as described provides both warning and illumination capabilities and further has the significant advantage of being able to be easily retracted into a bicycle handlebar (A) when the safety light is not in use, which greatly reduces the likelihood that the safety light will be damaged.
Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only. Changes may be made in detail, especially in matters of shape, size and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
