DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0023] Referring to the drawings, and initially to FIGS. 1 and 2, a
light leveling device in accordance with the present invention
comprises a base 10, and a supporting housing 20 disposed on the
base 10 and including a one or more seats 21 provided thereon for
supporting level vials 22 therein. The base 10 includes one or more
adjusting members 14, such as adjusting screws 14 attached to the
bottom thereof, to adjust the base 10 to a horizontal level or
position with the vials 22.
[0024] The housing 20 includes an orifice 23 formed therein for
receiving a laser or light instrument 30 received and positioned
therein. The laser or light instrument 30 includes a lens 31
attached to the front portion thereof and having two or more
vertical and parallel lines 32 formed or provided therein, for
forming or generating vertical and parallel lines 33 (FIGS. 5, 6)
on wall members (not shown).
[0025] The housing 20 further includes a notch or a chamber 24
formed therein and defined by a fence 25, and includes an aperture
26 formed in the fence 25 (FIGS. 2, 3), and communicating with the
chamber 24 of the housing 20. It is preferable that the aperture 26
of the fence 25 is extended in a direction perpendicular to the
orifice 23 of the housing 20 and to the laser or light instrument
30.
[0026] A carrier 40 includes a shaft 41 extended therefrom and
rotatably engaged through the aperture 26 of the fence 25, and
rotatably secured to the fence 25 with such as a retaining ring 42,
to allow the carrier 40 to be rotated and adjusted relative to the
fence 25 of the housing 20. The carrier 40 includes a gear or
roller or wheel 43 provided thereon, and preferably located
opposite or distal to the shaft 41.
[0027] The carrier 40 further includes a cavity 44 formed therein
for receiving another laser or light instrument 50 therein (FIG.
3). The laser or light instrument 50 also includes a lens 51
attached to the front portion thereof and having two or more
horizontal and parallel lines 52 formed or provided therein, for
forming or generating horizontal and parallel lines 53 (FIGS. 5, 6)
on wall members (not shown), and to allow the parallel lines 53 to
be perpendicular to the parallel lines 33 generated by the laser or
light instrument 30.
[0028] In operation, the carrier 40 is rotatable or adjustable
relative to the housing 20 to adjust and direct the laser or light
instrument 50 up and down relative to the housing 20, in order to
adjust the parallel lines 53 up and down relative to the parallel
lines 33 that are generated by the laser or light instrument 30,
best shown in FIGS. 5 and 6.
[0029] The base 10 or the housing 20 further includes a post 27
extended from such as the base 10, and having a bore 28 formed
therein. Another gear or roller or wheel 60 includes an axle 61
extended therefrom and rotatably engaged through the bore 28 of the
post 27 or of the housing 20 (FIG. 4), and rotatably secured to the
post 27 or the housing 20 with such as a retaining ring 62, to
allow the wheel 60 to be rotated and adjusted relative to the post
27 or the housing 20.
[0030] The wheel 60 is engaged with the wheel 43 of the carrier 40
(FIG. 1) with such as a gear-engagement, or a force-fitted
engagement, to allow the wheel 43 and thus the carrier 40 to be
rotated or adjusted relative to the post 27 or the housing 20 by
the wheel 60. A knob 63 may be secured to the wheel 60 or to the
axle 61 of the wheel 60 to rotate and adjust the wheel 60 and thus
the wheel 43 and the carrier 40 and the laser or light instrument
50 relative to the housing 20 and the laser or light instrument
30.
[0031] It is preferable that either or both of the wheels 43, 60
are made of rubber or coarse materials, to allow the wheels 43, 60
to be solidly contacted and engaged with each other, and to allow
the wheel 43 to be solidly and effectively rotated by the other
wheel 60. The laser or light instrument 50 may thus be effectively
rotated or adjusted relative to the housing 20 and the laser or
light instrument 30 by the wheel 60 and/or the knob 63.
[0032] The housing 20 and the post 27 and the base 10 may be formed
as a support member for supporting the laser or light instruments
30, 50 and the carrier 40 and the wheel 60. The light instrument 50
and the carrier 40 may be rotated or adjusted relative to the
housing 20 and the laser or light instrument 30 to any angular
position simply by the wheel 43, or by the knob 63 and the other
wheel 60.
[0033] In operation, as shown in FIG. 5, the lights or lines 33
generated by the light instrument 30 may be emitted onto and
retained on the wall members. As shown in FIG. 6, the carrier 40
may be rotated or adjusted relative to the housing 20 and the laser
or light instrument 30 to any angular position by the knob 63 and
the engagement between the wheels 43, 60.
[0034] It is to be noted that the base 10 and the housing 20 may
also be attached to a vertical wall (not shown) to have the
parallel lines 33 generated by the laser or light instrument 30 to
be arranged horizontally, and the parallel lines 53 generated by
the laser or light instrument 50 to be arranged vertically and
perpendicular to the horizontal lines 33.
[0035] A driving device 70, such as a motor 70 may further be
provided to drive or rotate or adjust the carrier 40 relative to
the fence 25 of the housing 20. For example, a roller or wheel or
gear 64 may be provided and attached to the carrier 40, or to the
axle 61 of the wheel 60. The driving device 70 or the motor 70 may
be attached to the post 27 of the housing 20 or of the base 10 with
such as a bracket 71, and includes a spindle 72 having another
roller or wheel or gear 73 attached thereto and engaged with the
gear 64 of the axle 61 or of the wheel 60 (FIG. 4).
[0036] As shown in FIG. 7, a control device 74 may be provided to
control or to operate the motor 70, and includes a processor device
75 coupled to the motor 70, in order to control or operate the
motor 70, and includes a signal receiving circuit 76 coupled to the
processor device 75, for signal receiving purposes. The control
device 74 further includes a signal controlling or emitting device
77 for emitting control signals to the signal receiving circuit 76,
in order to control or operate the motor 70 via the processor
device 75.
[0037] In operation, the carrier 40 may be automatically rotated or
adjusted relative to the housing 20 and the laser or light
instrument 30 to any angular position by the motor 70 via the
wheels 43, 60 and the gears 64, 73. In addition, the motor 70 may
be actuated or operated or controlled remotely by the control
device 74.
[0038] It is to be noted that the gear 73 of the motor 70 may also
be directly coupled to or engaged with the wheel 43 of the carrier
40, in order to directly rotate or control or adjust the carrier 40
relative to the housing 20 or the base 10.
[0039] Accordingly, the light leveling device in accordance with
the present invention includes a rotatable laser or light
instrument rotatable or adjustable relative to the support housing
automatically by the motor, and/or remotely by the control device,
for facilitating the leveling or plumbing purposes thereof.
[0040] Although this invention has been described with a certain
degree of particularity, it is to be understood that the present
disclosure has been made by way of example only and that numerous
changes in the detailed construction and the combination and
arrangement of parts may be resorted to without departing from the
spirit and scope of the invention as hereinafter claimed.
