Description
BACKGROUND OF THE INVENTION
[0001] (a) Technical Field of the Invention
[0002] This invention is related to a bicycle pump, and in
particular to one which can be conveniently used at night.
[0003] (b) Description of the Prior Art
[0004] The conventional bicycle pump does not have any illuminating
means for use at night. Hence, unless the user brings a flashlight
or something similar, she/he must operate the bicycle pump to fill
air into the tire in the dark at night by using her/his hands to
feel the way because of poor visibility. However, depending on poor
road conditions, it will be very difficult to maintain the correct
pressure filled into the tire thereby often causing flat tire when
traveling.
[0005] It is expected that the bicycle pump should be lightweight
and simple in construction. It should not does not have any
unnecessary attachments. A bicycle pump with a pressure gauge is an
inevitable equipment for a bicycle rider who has to travel for a
long distance. Nevertheless, none of the bicycle pumps on the
market can fulfill the need for using at night.
[0006] Therefore, it is an object of the present invention to
provide an improved bicycle pump which can obviate and mitigate the
above-mentioned drawbacks.
SUMMARY OF THE INVENTION
[0007] This invention is related to a bicycle pump which can be
used in the dark.
[0008] It is the primary object of the present invention to provide
a bicycle pump which includes a pump portion, a nozzle and a
pressure gauge mounted on the body portion, the pressure gauge
having an inlet connected to a lower end of the pump body and an
outlet connected to the nozzle, characterized in that the pressure
gauge is provided with a first illuminating means, and the nozzle
is provided with a second illuminating means therein.
[0009] It is another object of the present invention to provide a
bicycle pump wherein the nozzle has an upper end provided with an
illuminating seat in which is fitted the second illuminating means,
and the illuminating seat has a cover engageable with one side of
the nozzle and the rear end of the illuminating seat being provided
with a switch for controlling power supplied from batteries to the
second illuminating means.
[0010] It is a further object of the present invention to provide a
bicycle pump wherein the pressure gauge has a housing in which are
installed a plurality of batteries kept within the housing by a
battery cover via a screw, the first illuminating means having two
illuminating elements mounted at two opposite positions in the
housing and connected to the switch, the switch having an upper end
extending upwardly through a top of the housing.
[0011] The foregoing objects and summary provide only a brief
introduction to the present invention. To fully appreciate these
and other objects of the present invention as well as the invention
itself, all of which will become apparent to those skilled in the
art, the following detailed description of the invention and the
claims should be read in conjunction with the accompanying
drawings. Throughout the specification and drawings identical
reference numerals refer to identical or similar parts.
[0012] Many other advantages and features of the present invention
will become manifest to those versed in the art upon making
reference to the detailed description and the accompanying sheets
of drawings in which a preferred structural embodiment
incorporating the principles of the present invention is shown by
way of illustrative example.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0021] The following descriptions are of exemplary embodiments
only, and are not intended to limit the scope, applicability or
configuration of the invention in any way. Rather, the following
description provides a convenient illustration for implementing
exemplary embodiments of the invention. Various changes to the
described embodiments may be made in the function and arrangement
of the elements described without departing from the scope of the
invention as set forth in the appended claims.
[0022] Referring to FIG. 1, the bicycle pump 11 according to the
present invention comprises a pump body 111, a nozzle 13 and a
pressure gauge 12. The pressure gauge 12 is mounted on the pump
body 111 of the bicycle pump 11. The inlet of the pressure gauge 12
is connected to the lower end of the pump body 111 via a tube
(shown but not numbered). The outlet of the pressure gauge 12 is
connected to the nozzle 13 via a tube (shown but not numbered). An
LED (light-emitting diode) is mounted inside the pressure gauge 12.
An LED is fitted within the nozzle 13.
[0023] FIG. 2 illustrates the interior structure of the nozzle 13.
FIG. 3 is a front perspective view of the nozzle 13. FIG. 4 is a
rear perspective view of the nozzle 13. As shown, the nozzle 13
comprises a tube 131, an illuminating seat 14 on the upper portion
of the nozzle 13, and a cover 141 engageable with one side of the
nozzle 13. The rear end of the illuminating seat 14 is provided
with a switch 142 for controlling the power supplied from batteries
143 to the LED 144. When the switch 142 is turned on, the LED 144
will send out light through the nozzle 13.
[0024] FIG. 5 illustrates the arrangement of the illuminating
device in the pressure gauge 12. FIG. 6 illustrates the arrangement
of the illuminating device in the pressure gauge 12, with the
battery cover fastened in place. FIG. 7 illustrates the top view of
the pressure gauge 12 mounting with a pointer and a transparent
panel. FIG. 8 illustrates the top view of the pressure gauge 12
mounting with a positioning collar for keeping the transparent
panel in place. The pressure gauge 12 has a housing 121 in which
are installed a cylinder 15 and a telescopic screw rod 16 which is
drivingly connected with an axle 17 of the pointer. A plurality of
batteries 122 are fitted in a corner of the housing 121 and kept in
position by a battery cover 123 via a screw 124. Two illuminating
devices 125 are mounted at two opposite positions in the housing
121 and connected to two electrodes of the batteries 122 and the
switch 126. Except the switch 126, the other components are mounted
under the dial 127. The upper end of the switch 126 extends
upwardly through the dust cover 129 and the transparent panel for
pressing operation.
[0025] It will be understood that each of the elements described
above, or two or more together may also find a useful application
in other types of methods differing from the type described
above.
[0026] While certain novel features of this invention have been
shown and described and are pointed out in the annexed claim, it is
not intended to be limited to the details above, since it will be
understood that various omissions, modifications, substitutions and
changes in the forms and details of the device illustrated and in
its operation can be made by those skilled in the art without
departing in any way from the spirit of the present invention.
