`
`BACKGROUND OF THE INVENTION
`
`Field Of The Invention
`
`The
`
`present
`
`invention
`
`relates
`
`to
`
`solar
`
`rechargeable lights.
`
`Related Art
`
`Yard and walkway lights are well known for
`
`providing illumination of sidewalks, driveways, yards,
`
`-and so forth.
`
`These lights typically are powered
`
`To
`supply.
`through underground wiring or gas
`eliminate the need for such underground power supply,
`solar powered lights have been used which can be
`
`selectively placed irrespective of underground power
`supplies, as long as there is sufficient illumination
`of the solar panel to charge a battery sufficiently to
`power the light when darkness sets in.
`
`Such solar powered lights typically have been
`
`mounted on posts stuck in the ground and have had the
`
`light bulb placed on the bottom of the housing of the

`downward on a side of the housing from the top of the
`housing to 'the bottom.
`With
`this
`arrangement,
`however,
`placement of
`the light
`in the- desired
`
`location for optimum illumination of a selected area
`
`necessarily determined the orientation of the sloped
`
`if the light was
`0n the other hand,
`solar panel.
`positioned so as to optimize collection of solar rays
`in the solar panel, the selected area for illumination
`
`was not always properly lighted.
`
`There has been a
`
`need, therefore, for a solar powered light wherein the

`
`orientation of
`
`the light
`
`is
`
`independent of
`
`the
`
`orientation of the solar panel.
`I
`Prior solar powered lights were rigidly fixed
`
`to the standard or post on which the light housing was
`
`mounted. As a result, the light source always pointed
`
`down to illuminate the ground underneath the light.
`
`The light would illuminate a circular area centered
`around the solar powered light.
`The rigid structure
`
`of the light did not allow reorientation of the light
`
`to illuminate a different area. There also has been,
`
`therefore, a need for a solar powered light which can
`
`be adjusted for illuminating any number of selected
`
`areas from the same location.
`
`Prior solar lights were placed in the ground
`
`merely by sticking the support stake in the ground.
`
`Whenever
`
`the surrounding area. was
`
`to be mowed or
`
`cleaned,
`
`the light would be left in place,
`
`in which
`
`case it could be hit or bumped and possibly damaged or
`
`the area next
`
`to the stake could not be adequately
`
`maintained, or the stake could be removed from the
`
`ground.
`
`If the stake were removed from the ground,
`
`the hole is often widened through the action of
`
`withdrawing and
`
`replacing the stake, making the
`
`repositioning of the light unstable. Therefore, there
`
`has been a further need for a solar powered light
`
`which can be placed in the ground and repeatedly
`
`removed to allow mowing or cleaning in the surrounding
`
`area without
`
`loosening the surrounding soil with
`
`repeated removal of the stake.
`
`SUMMARY OF THE INVENTION
`
`Briefly,
`
`and in general
`
`terms,
`
`the present
`
`invention resides in a solar rechargeable light which

`
`the orientation of the light source is independent of
`the orientation of the solar panel, movement of the
`light
`source
`is
`allowed to change
`the
`area of
`illumination, and the light can be quickly and easily
`removed from the ground and replaced after mowing,
`trimming and so forth.
`
`invention, a
`In accordance with the present
`solar rechargeable light has a lamp for illuminating
`a selected area such as the ground or a wall.
`A base
`is adapted to support the lamp in a fixed position to
`illuminate the selected area.
`An electrical storage
`device and power supply is electrically coupled to the
`lamp.
`A solar panel
`is electrically coupled to the
`electrical storage device for charging the storage
`device when the solar panel
`is exposed to 'light,
`wherein current from the storage device energizes the
`lamp, and wherein the solar panel is moveable relative
`
`to the base so that the orientation of the solar panel
`is substantially independent of an orientation of the
`
`lamp
`relative to the selected area.
`With this
`invention,
`the lamp
`and the solar panel
`can be
`oriented-independently of one another to optimize the
`collection of solar rays and still provide the desired
`,illumination at the same time.
`
`the solar panel is
`In a preferred embodiment,
`rotatable about an axis relative to the base through
`an angle of only less than 360". This minimizes the
`
`possibility of entanglement of any wires or conductors
`which may be used in the solar rechargeable light.
`Additionally,
`the base may include a mount which is
`releasably fixed to the base so that the base and lamp
`can be adjusted in position relative to the support.

`
`opens the circuit between the battery and the lamp
`bulb to prevent further draining of the battery. The
`battery can then be recharged.
`A further circuit is
`included 'for keeping an open circuit between the
`
`battery and the lamp bulb when there is sufficient
`ambient light, for example from the sun, to illuminate
`
`the solar panel. The electronic circuit is preferably
`moisture r§Sistant.
`
`_In;the,disclosed embodiment,
`
`a low battery

`solar
`
`panel
`
`(FIG. 4).
`
`The
`
`indicator 46 may be an LED coupled to the electrical
`
`circuit 24 and is illuminated when the battery charge
`level approaches 30% of maximum. Alternatively,
`the
`battery indicator may be omitted.
`
`'
`
`Ingthe disclosed embodiment,
`
`the base 16 and
`
`the cover 38 are circular in plan View and engage at
`
`their circumferential edges in an overlapping junction

`
`the cover allows the rim of the base to support the
`
`outer edge of the cover which allows rotation of the
`
`the sliding
`cover relative to the base. Moreover,
`joint between the cover and the base around the entire
`
`circumference thereof provides centering, interlocking
`stability and mutual alignment of the cover and the
`
`base.
`
`The rims take some of the centering pressure
`
`off the pivot cylinders and distributes it around the
`
`edges of the base and cover.
`
`The

`The lengths of the base cylinder and the stop
`
`cylinder from the bottom 58 are such as to provide a
`
`uniform tension in the compression spring 64 when the
`
`bolt is threaded until the washer stops against the
`stop cylinder.
`This provides the desired amount of
`
`frictional engagement between the base and cover while
`
`still allowing manual rotation of the cover.
`
`The conductors 34 and 36 are sufficiently long
`
`to allow rotation of the cover relative to the base
`about 366'.
`A pair of posts 64
`(FIG. 5;
`shown in
`
`phantom in FIG. 4) extend downwardly on each side of
`
`the low battery indicator 46.
`
`The posts
`
`extend
`
`downwardly a distance sufficient to come into contact
`
`with walls 66 in the base defining a cavity 68 for
`accommodating a hinge 70,
`to be described more fully
`below.
`The cover can rotate relative to the base in
`
`one direction until the first post contacts the wall
`
`of the cavity 68
`
`(FIG. 6).
`
`The contact between the
`
`post and the wall prevents wrapping of the conductors
`
`around the pivot cylinders.
`
`The cover can be rotated
`
`in the other direction until the second post contacts

`
`the opposite wall of the cavity 68. This prevents the
`
`conductors from wrapping around the pivot cylinders in
`
`the other direction.
`
`The full extent of rotation of
`
`the cover, however, approaches 360°
`
`and allows for
`
`almost any desired orientation of
`
`the solar' panel
`
`in a horizontal plane, of
`regardless of the position,
`the lamp bulb.
`This allows for optimum exposure of
`the solar panel to light rays while still allowing the
`best possible positioning of
`the light source for
`illuminating the selected area of the ground, wall or
`the like.
`
`The base and cover are made of a suitable
`
`The first, second and third pivot cylinders
`plastic.
`are dimensioned along with the spring and bolt in such
`
`a way as to allow easy manual rotation of the cover
`while still providing sufficient frictional engagement
`between the rims and cylinders of the cover and base
`
`from rotating when no force is
`to keep the cover
`applied to the cover.
`
`a cylindrical hinge
`The cavity 68 accepts
`element 70
`in a manner" which allows the hinge to
`rotate about a horizontal axis extending from the left
`to the right side of the base.
`The cavity defines an
`inverted round-bottomed trough enclosed at each end by
`straight sides.
`The cylindrical hinge element rests
`
`and rotates in the trough and is held in place by each
`side of the trough.
`The hinge element is rotatably
`cradled in cusps
`in the sides of
`the trough by
`protrusions on each end of the hinge element.
`The
`hinge element is releasably fastened in place in the
`trough by a bolt 72 and friction nut 74 so that the
`base and cover can be rotated about the hinge element

`
`to change the orientation of
`
`the light and solar
`
`panel. A slot 76 in the hinge element allows rotation
`
`of the hinge element relative to the bolt.
`
`A mounting-post 78 is coupled to the hinge
`
`element 70
`
`to allow the rechargeable light
`
`to be
`
`mounted to a light stand 80 which can then be anchored
`
`in the ground or
`
`to a wall mounting bracket 82
`
`(FIG. 7)' for mounting to another suitable support
`surface.
`
`As
`
`shown in FIG. 2,
`
`the light stand can be
`
`inserted on the mounting post 78 and then used in
`
`conjunction with a ground stake 84
`
`so that
`
`the
`
`rechargeable
`
`light
`
`can
`
`illuminate the
`
`ground or
`
`walkway, etc. The ground stake preferably includes a
`
`plurality of flanges 86 to maintain a stable anchor
`
`for the lightr
`
`The ground stake also has a flat,
`
`horizontally "extending rim 88
`
`to be placed flush
`
`against the ground to provide a low profile for the
`
`ground stake and to provide a bearing surface for
`
`pushing'
`
`the ground stake into the ground. After
`
`installing the light, the light stand and light can be
`rembved from the ground stake so that the
`
`surrounding area can be mowed,
`
`trimmed or-otherwise
`
`maintained.
`
`As
`
`shown
`
`in FIG. 3,
`
`the bolt 72
`
`can be
`
`loosened to allow the hinge_element to rotate within
`
`the cavity 68 to change the planar orientation of the
`base and cover of
`the light.
`This
`changes
`the
`
`selected area of illumination for the light.
`
`It can
`
`also be used to change the slant angle of the solar
`panel as a function of geographic latitude.
