Adjustable front lamp for a bicycle

[0002] 1. Field of the Invention

[0003] The present invention is related to an attachment for a bicycle, and more particularly to a front lamp for the bicycle.

[0004] 2. Description of Related Art

[0005] Referring to FIG. 6, a bicycle usually has a front lamp (64) assembled on a handlebar (62) thereof. The handlebar is connected with a head tube (60) by a stem (61) and has a pair of grips (63) respectively provided at two distal ends thereof. The front lamp (64) is fastened on the handlebar (62) by a C-like clamp (65). When a user wants to change an angle of the front lamp (64) to the handlebar (62), he or she must adjust it before starting to ride as it is difficult and dangerous for the user to adjust the lamp (64) during riding. Furthermore, after adjusting the clamp (65) many times, it will lose flexibility and cannot fasten the front lamp (64) tightly. Thus, the front lamp (64) cannot be held at a desired angle whereby the road ahead is not properly illuminated and thus the rider is exposed to danger. Therefore, the invention provides an adjustable front lamp to mitigate and/or obviate the aforementioned problems.

[0006] The main objective of the present invention is to provide a front lamp for a bicycle which is able to be safely adjusted by a user while riding the bicycle. Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

[0012] FIG. 6 is a perspective view of a conventional front lamp for a bicycle.

[0013] Referring to FIGS. 1-3, a front lamp for a bicycle in accordance with the present invention is composed of a stem (10) and a lamp seat (30).

[0014] The stem (10), which is assembled between a tube and a handlebar (not shown or numbered) of a bicycle, has an upright C-like hole (11) defined at a rear end thereof, and a lateral C-like hole (12) defined at a front end thereof. By use of screws (not shown or numbered), the tube and the handlebar are respectively extended through and fastened in the upright C-like hole (11) and the lateral C-like hole (12). A chamber (19) is defined in the stem (10) to receive a battery seat (14) therein. Batteries (not numbered) can be installed in the battery seat (14). A buzzer (13) is provided beneath and electrically connected with the battery seat (14). A buzzer switch (15) is provided on the battery seat (14) and extends out from the chamber (19).

[0015] A cover (20) is provided on the top of the chamber (19). A bar (21) is laterally formed on an inner face at a front end thereof. A buzzer button (22) is provided on the cover (20) and engaged with the buzzer switch (15).

[0016] A convex arcuate face (16) is formed at the front end of the stem (10). A protrusion (18) is formed at a central portion of the convex arcuate face (16), and a pair of fins (17) is formed at two sides of the protrusion (18) respectively.

[0017] The lamp seat (30) being composed of an upper housing (40) and a lower housing (50), is assembled on the front end of the stem (10). The upper housing (40) has a tongue (41) formed at a rear end thereof and extending between the cover (20) and the stem (10). A plurality of teeth is (42) formed on the tongue (41), and the bar (21) is engaged with one of the teeth (42). The lower housing (50) has a concave arcuate face (51) to correspond to the convex arcuate face (16) of the stem (10). The fins (17) of the stem (10) are abutted to the concave arcuate face (51) and the protrusion (18) extends out from a first slot (53) longitudinally defined in the concave arcuate face (51), as shown in FIG. 5.

[0018] Two lugs (52) are formed at an upper end of the lower housing (50) and two second slots (54) are respectively defined on two sides of the first slot (53). Above the second slots (54), two ears (55) are respectively formed on two opposite side walls of the lower housing (50).

[0019] A flexible sheet (31) is received between the ears (55) and a bottom inner face of the lower housing (50), The flexible sheet (31) has a third slot (32) defined therein which is in alignment with the first slot (53) when the flexible sheet (31) is fitted to the lower housing (50). Two triangular protrusions (33) are respectively formed at two sides of the third slot (32) and extend out from the second slots (54). Two apertures (39) are defined therethrough for the lugs (52) of the lower housing (50) respectively extending thereout.

[0020] A lamp switch (34) is provided in the lamp seat (30) and electrically connected with the battery seat (14). A lamp button (35) is provided in the upper housing (40) and engaged with the lamp switch (34).

[0021] An illuminating member (36) is assembled at a front end of the lamp seat (30) and controlled by the lamp switch (34). A bezel (37) is assembled at a front end of the illuminating member (36) A ring (38) covering both the bezel (37) and the illuminating member (36) is engaged with the lamp seat (30) to fasten the bezel (37) and the illuminating member (36).

[0022] Referring to FIG. 4, a user can switch on the illuminating member (36) by pressing the lamp button (35), and can switch on the buzzer (13) by pressing the buzzer button. Moreover, in riding, the user can adjust an angle of the front lamp by pressing down or pulling up the lamp seat (30). When a user adjusts the angle of the lamp, the lamp seat (30) is moved along the convex arcuate face (16) of the stem (10), the protrusion (18) is moved along the first slot (53) and the third slot (32), and the fins (17) are moved along the concave arcuate face (51) of the lower housing (50). At the same time, the bar (21) is engaged with another one of the teeth (42) to position the lamp seat (30) at a desired angle.

[0023] From the above description, it is noted that the invention has the following advantages:

[0024] 1. It is very convenient and safe for a user to adjust the front lamp while riding the bicycle.

[0025] 2. The lamp seat is able to be held at the desired angle by the engagement between the bar and the teeth.

[0026] 3. The front lamp has a dual-function in that it can be used as a light and a horn.

[0027] It is to be understood, however, that 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, and 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.
