patent application Ser. No. 11/120,869 filed on May 3, 2005, now
U.S. Pat. No. 7,390,051, issued Jun. 24, 2008. The disclosures of
the above applications are incorporated herein by reference.
FIELD
[0002] The present disclosure relates to golf cars and to a front
windshield assembly for a golf car.
BACKGROUND
[0003] The statements in this section merely provide background
information related to the present disclosure and may not
constitute prior art.
[0004] Golf cars provide transportation for golfers around a golf
course. In addition, a golf car must also securely carry a golf bag
in a location for convenient access throughout a round of golf.
Many golf cars are equipped with a front windshield assembly for
providing a transparent barrier to the passengers of the golf car.
A front windshield can protect the passengers from weather, debris,
and other objects such as insects and golf balls, for example. In
one configuration, a front windshield assembly is attached between
a pair of upwardly extending struts arranged on a front end of the
golf car. The struts define a window frame and typically connect
with a roof structure of the golf car. In other arrangements, the
window frame may be free standing at an upper end.
[0005] Some windshield assemblies on golf cars provide a two-part
collapsible window pane arrangement. Typically, a pair of window
panes may include an upper pane and a lower pane. The upper and
lower panes may be arranged one on top of the other in a vertical
orientation. In one arrangement, a flexible coupling member may
connect the upper and lower pane together. In such an arrangement,
the upper pane may be movable from an upright position to a
collapsed position. In a collapsed position, the upper pane may
pivot about the flexible coupling member to a position alongside
the lower pane. As a result, a passage is formed through the window
frame for air to freely pass.
[0006] In another configuration, a three pane window arrangement
may be provided. In such an arrangement, a flexible coupling member
may connect two of the windows such as the lower and intermediate
pane together. The intermediate pane may be movable from an upright
position to a collapsed position.
[0007] For each of the two pane and three pane windshield
configurations, it is necessary to selectively retain the
respective panes against the struts while in the upright and
collapsed position. In one non-limiting example, retaining members
may be used to capture the respective panes against the struts. In
this regard, it is also necessary to provide retaining members that
allow a user easy manipulation of the panes when moving between
upright and collapsed positions.
[0008] In one non-limiting example, retaining members may be formed
exclusively of extruded elastomeric material. In some instances,
forming retaining members from extruded elastomeric material
results in retaining members having a substantially constant
cross-section. Typically, an extruded elastomeric retaining member
having a consistent cross section may offer uniform stress
resistance across the body of the retaining member. In some
applications however, it would be desirable to configure a
retaining member to provide additional strength at critical areas
about its geometry.
SUMMARY
[0009] A window assembly cooperating with a window frame on a golf
car cooperating with a window frame on a golf car can include a
first window pane that is selectively coupled to the window frame.
A second window pane can be selectively coupled to the window frame
and offset from the first window pane. A first pair of retaining
members can be arranged on the window frame in an installed
position and movable between a retaining position wherein the
retaining members retain the first window pane in an upright
position and a release position wherein the retaining members are
disengaged from the first window pane. Each of the first pair of
retaining members are defined by a rigid frame having an integrally
molded elastomeric body.
[0010] According to additional features, the window frame can
define a pair of generally upright struts. Each rigid frame can be
configured to cooperatively mate with the respective struts in the
installed position. Each rigid frame can define an integrally
formed protrusion adapted to be received by respective apertures
defined in the respective struts in the installed position. Each
rigid frame can generally define a U-channel. The elastomeric body
can be molded around an inboard face of the rigid frame, thereby
forming an elastomeric barrier in the installed position between
the respective rigid frames and the respective struts. The
elastomeric body can be molded around an outboard face of the rigid
frame, thereby forming an elastomeric barrier in the retaining
position between the respective rigid frames and the first window
pane. The elastomeric body can define hook portions that are
operable to securably engage an outboard face of the first window
pane in the upright position.
[0011] According to still other features, the window assembly can
include a second pair of retaining members. Each of the retaining
members can be defined by a rigid frame having an integrally molded
elastomeric body. The second pair of retaining members can be
arranged on the window frame in an installed position and are
operable to retain the second window pane in an upright position.
Each of the second pair of retaining members can define an
intermediate finger that is adapted to locate between the first and
second window panes when the first window pane is moved to a
collapsed position adjacent to the second window pane.
[0012] Further areas of applicability of the present disclosure
will become apparent from the detailed description provided
hereinafter. It should be understood that the detailed description
and specific examples, while indicating the preferred embodiment of
the disclosure, are intended for purposes of illustration only and
are not intended to limit the scope of the disclosure.

DETAILED DESCRIPTION
[0039] The following description of the preferred embodiment(s) is
merely exemplary in nature and is in no way intended to limit the
disclosure, its application, or uses.
[0040] With initial reference to FIG. 1, a three pane windshield
assembly constructed in accordance to the present teachings is
shown and identified generally at reference 10. The three pane
windshield assembly is illustrated operably connected to an
exemplary golf car 12. It is appreciated that the golf car 12 is
merely exemplary and that the multiple pane windshield assembly 10
may be adapted for use with other golf car configurations.
Furthermore, the multiple pane windshield assembly described herein
is not limited for use with golf cars and may also be used with
other vehicles such as, but not limited to, utility vehicles,
lawnmowers and other turf care vehicles.
[0041] The golf car 12 generally includes a front end 16, a rear
end 20 having a golf bag storage area 22, and a passenger seating
area 24. The passenger seating area 24 may include a steering wheel
26, accelerator and brake pedals (not shown), a seat 30, and a
floor portion 32. The golf car 12 further includes an overhead
assembly 36. The overhead assembly 36 generally includes a pair of
front struts 38 supporting the three pane windshield assembly 10.
The overhead assembly 36 may be interconnected between the front
end 16 of the golf car 12 and a roof portion 40. A pair of rear
struts 42 extend between the rear end 20 of the golf car 12 and the
roof portion 40. The overhead assembly 36 provides protection for
the vehicle passengers from the sun, but in some embodiments can
protect against weather, debris, and other objects.
[0042] The pair of front struts 38 collectively define a window
frame 44. A lower end 46 of the window frame 44 may be secured
mechanically to the front end 16 of the golf car 12 such as by
conventional fasteners 48. An upper end 50 of the window frame 44
may likewise secure mechanically to the roof 40 of the golf car 12.
It is appreciated that alternatively, the front and rear struts 38
and 42, respectively, may be integrally formed and collectively
define an intermediate frame (not shown) extending along an
underside of the roof 40. Other fastening arrangements for the
upper end 50 and the lower end 46 of the window frame 44 are also
contemplated. The lower end 46 of the window frame 44 defines a
curved portion for cooperating with the geometry of the front end
16 of the golf car 12. The window frame 44 may be comprised of a
rigid material such as metal or plastic.
[0043] With continued reference to FIG. 1 and further reference to
FIG. 2, the three pane windshield assembly 10 will be described in
greater detail. The three pane windshield assembly 10 includes a
first or upper window pane 54, a second or lower window pane 56,
and a third or intermediate window pane 60. The upper window pane
54 defines a planar section. The upper window pane 54 is secured to
the window frame 44 and arranged adjacent to the roof portion 40.
In one non-limiting example, the upper window pane 54 is secured to
the window frame 44 by way of conventional fasteners 64. Other
fastening arrangements may be employed. The upper window pane 54
defines a top lateral edge 70, a bottom lateral edge 72, and a pair
of side edges 74.
[0044] The lower window pane 56 is secured to the window frame 44
and arranged adjacent to the front end. In one non-limiting
example, the lower window pane 56 is secured to the window frame 44
by way of conventional fasteners 78, although other fastening
arrangements are contemplated. The lower window pane 56 defines a
top lateral edge 80, a bottom lateral edge 82, and a pair of side
edges 84. A lower portion 88 of the lower window pane 56 defines a
curved section adapted to cooperate with the curved portion of the
lower end 46 of the window frame 44. It is appreciated that the
bottom lateral edge 82 of the lower window pane 56 may
alternatively terminate at the curved portion of the window frame.
As a result, the lower pane may alternatively define a planar
section. As illustrated in FIG. 3, the top lateral edge 80 defines
a curved flange 92. The curved flange 92 provides additional
structural support to the lower window pane 56.
[0045] The intermediate window pane 60 defines a planar section
extending between the front struts 38. The intermediate window pane
60 defines a first end 94, a second end 96, and opposite sides 98.
In an upright position (FIG. 2), the intermediate window pane 60 is
bordered on the first end 94 by the upper window pane 54 and
bordered on the second end 96 by the lower window pane 56. A
flexible coupling member 100 operably connects the intermediate and
lower window panes 60 and 56, respectively. The flexible coupling
member 100 is attached to the second end 96 of the intermediate
window pane 60 and the top lateral edge 80 of the lower window pane
56. The second end 96 of the intermediate window pane 60 defines a
curved flange 104 (FIG. 3). The curved flange 104 provides
additional structural support to the intermediate window pane 60.
The curved flanges 92 and 104 each lie inboard of the front struts
38.
[0046] As will be described, the flexible coupling member 100 is
adapted to provide a pivot axis whereby the intermediate window
pane 60 may be moved from the upright position (FIG. 2) to a
collapsed position (FIG. 3). The flexible coupling member 100 may
be made from a durable resilient material such as rubber. The
flexible coupling member 100 may be attached to the intermediate
and lower window panes 60 and 56, respectively, by a press-fit,
mechanical fasteners, or chemical bonding for example.
[0047] The three piece windshield assembly 10 is supported by the
window frame 44. More specifically, the window frame 44
collectively defines a pair of forward mounting surfaces 110. The
upper, lower, and intermediate window panes 54, 56, and 60 are
configured adjacent to forward mounting surfaces 110. A first and
second pair of retaining members 112 and 114, respectively, are
coupled to the window frame 44. The first pair of retaining members
112 generally define a C-shaped body portion 122 including a
forward hook portion 124 and a rearward hook portion 126. The
second pair of retaining members 114 generally define an M-shaped
body portion 130 including a forward hook portion 132, a rearward
hook portion 134 and an intermediate finger portion 136. The first
and second pair of retaining members 112 and 114, respectively, are
operable to securely capture the intermediate window pane 60 at the
upright position (retaining members 112, FIG. 3) and the collapsed
position (retaining members 114, FIG. 4).
[0048] The first pair of retaining members 112 are arranged on the
window frame 44 to align with an upper portion 138 of the
intermediate window pane 60 in the upright position. More
specifically, the forward hook portions 124 are aligned to capture
the intermediate window pane 60 against the forward mounting
surfaces 110 of the window frame 44 in the upright position (FIG.
2). The second pair of retaining members 114 are arranged on the
window frame 44 to align with the upper portion 138 of the
intermediate window pane 60 in the collapsed position (FIG. 3).
More specifically, the forward hook portions 132 are aligned to
capture the intermediate window pane 60 against the intermediate
finger portion 136. The first and second pair of retaining members
112 and 114, respectively, may be made from flexible, resilient
material such as, but not limited to rubber.
[0049] Movement of the intermediate window pane 60 from the upright
position to the collapsed position will now be described in greater
detail. At the outset, the first pair of retaining members 112 are
pulled outwardly at the forward hook portions 124 to a position
(represented in phantom line) allowing the intermediate window pane
60 to clear the first pair of retaining members 112. Once the
intermediate window pane 60 clears the first pair of retaining
members 112, they may be released to their relaxed position
(represented in solid line).
[0050] Next, the intermediate window pane 60 rotates generally
about the flexible coupling member 100 and is captured by the
second pair of retaining members 114. In one non-limiting example,
the second pair of retaining members 114 may be flexed outwardly
(represented in phantom line) to accept the intermediate window
pane 60 between the forward hook portions 132 and intermediate
finger portions 136. The second pair of retaining members 114 may
then be released causing the intermediate window pane 60 to nest
between the forward hook portions 132 and the intermediate finger
portions 136 (represented in solid line).
[0051] Returning now to FIG. 1, the three pane windshield assembly
10 provides favorable viewing advantages. For example, as shown, a
passenger P has a visibility range V through the intermediate
window pane 60, unimpeded by a window seam, window transition, or
other barrier. Explained further, a vertical height H (FIG. 2)
defines a vertical viewing space. A centerline C defines a
horizontal line through a midpoint of the height H. As shown, the
respective transitions between adjacent windows 54, 56, and 60 are
offset from the centerline C for improved visibility. The upper
window pane 54 may be coated with a reflective layer allowing the
passenger P to view in a rearward direction R. In one non-limiting
example, the upper window pane 54 may be manufactured to allow both
forward vision and rearward vision concurrently. Additionally, or
alternatively, the upper window pane 54 may be tinted. In one
non-limiting example, each window pane 54, 56 and 60 may be made of
durable plastic.
[0052] With reference now to FIGS. 4-6, a three pane windshield
assembly 210 constructed according to additional features of the
present disclosure will be described. For simplicity, similar
features associated with the three pane windshield assembly 210
will include reference numerals increased by 200 from the three
pane windshield assembly 10 described above.
[0053] The three pane windshield assembly 210 is illustrated
operably connected to an exemplary golf car 212. The golf car 212
generally includes a front end 216, a rear end 220 having a golf
bag storage area 222, and a passenger cabin area 224. Again, it is
appreciated that the golf car 212 is merely exemplary and that the
three pane windshield assembly 210 may be adapted for use with
other golf car configurations. The golf car 212 includes an
overhead assembly 236. The overhead assembly 236 generally includes
a pair of front struts 238 supporting the three pane windshield
assembly 210.
[0054] The pair of front struts 238 collectively define a window
frame 244. A lower end 246 of the window frame 244 may be secured
mechanically to the golf car 212 such as by conventional fasteners
248. An upper end 250 of the window frame 244 may likewise secure
mechanically to the roof 240 of the golf car 212. The lower end 246
of the window frame 244 defines a generally linear portion for
cooperating with the geometry of the golf car 212.
[0055] With continued reference to FIG. 4 and further reference to
FIG. 5, the three pane windshield assembly 210 will be described in
greater detail. The three pane windshield assembly 210 includes a
first or upper window pane 254, a second or lower window pane 256
and a third or intermediate window pane 260. The upper window pane
254 defines a pair of C-channel portions 255 integrally formed
thereon. The C-channel portions 255 cooperate to form a friction
fit around the upper portion of the window frame 244. A gap 257 is
defined between the C-channel portions 255 for accommodating a sign
holder or other identifier (not specifically shown). The C-channel
portions 255 are formed on a top lateral edge 270 of the upper
window pane 254. The upper window pane 254 further defines a bottom
lateral edge 272 and a pair of side edges 274. As shown, the bottom
lateral edge 272 defines a curved section for increased
stability.
[0056] The lower window pane 256 is secured to the window frame 244
by a pair of retaining members or windshield supports 275. The
windshield supports 275 are secured to the window frame 244 by
fasteners such as push pins 277 to capture the lower window pane
256 against the window frame 244. A pair of compliant hook portions
279 are arranged along a front face of each windshield support 275.
As will be described in detail, the hook members 279 are adapted to
capture the intermediate window pane 260 in the collapsed position.
The windshield supports 275 are symmetric and may be used on either
side of the window frame 244. The windshield supports 275 may
comprise a durable lightweight material such as plastic for
example.
[0057] The lower window pane 256 defines a top lateral edge 280
(FIG. 5), a bottom lateral edge 282 and a pair of side edges 284. A
lower portion 288 of the lower window pane 256 defines a curved
section for increased stability. Similarly, the top lateral edge
280 defines a curved flange 292.
[0058] With particular reference to FIG. 5, the intermediate window
pane 260 defines a planar section extending between the front
struts 238. The intermediate window pane defines a curved flange at
a first end 294, a second end 296 and opposite sides 298. In an
upright position (FIG. 5), the intermediate window pane 260 is
bordered on the first end 294 by the upper window pane 254 and
bordered on the second end 296 by the lower window pane 256. The
opposite sides 298 define notch portions 299 for receiving the hook
portions 279 in the collapsed position (FIG. 6). A flexible
coupling member 300 is attached to the second end 296 of the
intermediate window pane 260 and the top lateral edge 280 of the
lower window pane 56. The second end 296 of the intermediate window
pane 260 defines a curved flange 304. The curved flanges 292, 294,
and 304 each lie inboard of the front struts 238.
[0059] Movement of the intermediate window pane 260 from the
upright position to the collapsed position will now be described in
greater detail. At the outset, the retaining members 312 are pulled
outwardly at the forward hook portions 324 to a position
(represented in phantom line) allowing the intermediate window pane
260 to clear the retaining members 312.
[0060] Next, the intermediate window pane 260 rotates generally
about the flexible coupling member 300 and is captured by the hook
portions 279. In one non-limiting example, the hook portions 279
may be flexed outwardly (represented in phantom line) to accept the
intermediate window pane 260 at the notch portions 299. In another
non-limiting example, the angled surfaces of the hook portions 279
may influence the hook portions 279 to bias outwardly upon pressing
the intermediate window pane 260 therebetween.
[0061] Returning now to FIG. 4, the three pane windshield assembly
210 provides the favorable viewing advantages as described in
relation to the there pane windshield assembly 10. More
specifically, a passenger P has a visibility range V through the
intermediate window pane 260. Furthermore, the upper window pane
254 may be coated with a reflective layer allowing the passenger P
to view in a rearward direction R. In one non-limiting example,
each window pane 254, 256 and 260 may be made of durable
plastic.
[0062] With reference now to FIGS. 7-16, a two pane windshield
assembly 330 according to various embodiments. The two pane
windshield assembly 330 is shown cooperating with a golf car 332
having an overhead assembly 336. The overhead assembly 336
generally includes a pair of front struts 338 supporting the two
pane windshield assembly 330. The overhead assembly 336 may be
interconnected between a front end 340 of the golf car 332 and a
roof portion 342. A pair of rear struts (not shown) may extend
between a rear end of the golf car 332 and the roof portion
342.
[0063] The pair of front struts 338 collectively define a window
frame 344. A lower end 346 (FIG. 9) of the window frame 344 may be
secured mechanically to the front end 340 of the golf car 332. An
upper end of the window frame 348 may likewise secure mechanically
to the roof 342 of the golf car 332. The lower end 346 of the
window frame 344 may define a curved portion for cooperating with
the geometry of the front end 340 of the golf car 332. The window
frame 344 may be formed of a rigid material such as metal or
plastic.
[0064] With specific reference to FIGS. 7-10, the two pane
windshield assembly 330 will be described in greater detail. The
two pane windshield assembly 330 includes a first or upper window
pane 350 and a second or lower window pane 352. The upper window
pane 350 is selectively secured to the window frame 344 by way of a
first pair of retaining members 356. The upper window pane 350
defines a top curved flange 360, a bottom curved flange 362, and a
pair of side edges 364.
[0065] The lower window pane 352 is secured to the window frame 344
and arranged adjacent to the front end 340. In one non-limiting
example, the lower window pane 352 may be secured to the window
frame 344 by way of a second pair of retaining members 366. The
lower window pane 352 defines a top lateral edge 368 (FIG. 9), a
bottom edge 370, and a pair of side edges 372. It is appreciated
that the bottom edge 370 of the lower window pane 352 may
alternatively terminate at a curved lateral edge similar to that
shown in FIG. 2. In another non-limiting example, the lower window
pane 352 may alternatively define a planar section. As illustrated
in FIG. 9, the top lateral edge 368 defines an upper curved flange.
The curved flange provides additional structural support to the
lower window pane 352.
[0066] A flexible member 376 operably connects the upper and lower
window panes 350 and 352, respectively. The flexible member 376 may
be attached to the bottom curved flange 352 of the upper window
pane 350 and the upper curved flange 368 of the lower window pane.
As will be described, the flexible coupling member 376 is adapted
to provide a pivot axis whereby the upper window pane 350 may be
moved from an upright position (FIG. 7) to a collapsed position
(FIG. 8). The flexible coupling member 376 may be made from a
durable resilient material such as rubber. The flexible coupling
member 376 may be attached to the upper and lower window panes, 350
and 352, respectively, by a press-fit, mechanical fasteners, or
chemical bonding for example.
[0067] With specific reference now to FIGS. 11-13, the first pair
of retaining members 356 will be described in greater detail. For
simplicity, a single retaining member 356 is shown in FIGS. 11-13.
The following discussion will be directed to one of the first pair
of retaining members 356 on the front strut 338 shown in FIG. 7;
however, it is appreciated that the same retaining member 356 may
be adapted for use on the other front strut 338.
[0068] The first pair of retaining members 356 are formed of a
rigid frame 380 having an integrally molded elastomeric body 382
(FIG. 13). In one non-limiting example, the rigid frame 380 may be
overmolded with elastomeric material. The rigid frame 380 may be
formed of plastic, metal or other rigid material. The elastomeric
material forming the elastomeric body 382 may comprise rubber for
example. The rigid frame 380 discourages cracking or splitting of
the retaining member 356 and provides strength to the retaining
members 356 as a whole.
[0069] The retaining member 356 defines a main body portion 384
having a central section 386 and a pair of opposing legs 388
collectively defining a U-channel. A hook portion 390 extends
outboard from the central face 386 of the main body portion 384.
The hook portion 390 defines a ramp 392 for facilitating
cooperation with the upper window pane 350 when pivoting from a
collapsed position to an upright position. The upper window pane
350 nests between the hook portion 390 and the central section 386
in the upright position (FIGS. 7 and 13). A pair of opposing tangs
396 are defined at terminal ends of the legs 388. The rigid frame
380 defines a pair of studs 398 extending generally parallel to the
legs 388. The studs 398 are adapted to be received by a
complementary pair of openings 400 defined in the strut 338 (FIG.
10). It is appreciated that one or more studs 398 may be provided
on the retaining member 356. In this way, the retaining member 356
may be precluded from sliding along the strut 338 in an assembled
position.
[0070] The rigid frame 380 (FIG. 13) further defines a pair of
opposing heel portions 404. The heel portions 404 provide strength
at the legs 388 and encourage a secure fit around the strut 338 in
an installed position (FIG. 13). The heel portions 404 and, as a
result, the legs 388 provide an inward taper to facilitate assembly
of the retaining member 356 around the strut 338. It is appreciated
that the legs 388 of the retaining member 356 provide a degree of
flexibility such that when assembled to a strut 338, the legs 388
flex outwardly as the retaining member 356 is advanced downwardly
(as viewed in FIG. 13) until the tangs 396 clear the strut 338. The
cooperation of the stud 398 and the interaction of the legs 388
with the strut 338 provide a snap-fit for the retaining member 356.
In this way, no supplemental fasteners are needed.
[0071] With specific reference now to FIGS. 14-16, the second pair
of retaining members 366 will be described in greater detail. For
simplicity, a single retaining member 366 is shown in FIGS. 14-16.
The following discussion will be directed to one of the second pair
of retaining members 366 on the front strut 338 shown in FIG. 7,
however, it is appreciated that the same retaining member 366 may
be adapted for use on the other front strut 338.
[0072] As with the first pair of retaining members 356, the second
pair of retaining members 366 are formed of a rigid frame 420
having an integrally molded elastomeric body 422 (FIG. 16). The
rigid frame 420 may be overmolded with elastomeric material. The
rigid frame 420 may be formed of plastic, metal or other rigid
material. The elastomeric material forming the elastomeric body 422
may comprise rubber for example.
[0073] In general, the retaining member 366 defines a main body
portion 426 having a central section 428 and a pair of opposing
legs 430 collectively defining a U-channel. An intermediate finger
432 extends from the central section 428. The intermediate finger
432 is adapted to capture the lower window pane 352 against the
central section 428. The intermediate finger 432 and the central
section 428 may define ribs for encouraging grip to the lower
window pane 352. As best illustrated in FIG. 15, a passage 440 is
defined on the retaining member 366. The passage 440 is operable to
receive a tab 442 (FIG. 9) defined on the sides 372 of the lower
window pane 352. As a result, the lower window pane 352 is
precluded from advancing vertically along the strut 338.
[0074] A hook portion 446 extends outboard from the intermediate
finger portion 432. The hook portion 446 defines a ramp 450 for
facilitating cooperation with the upper window pane 350 when
pivoting from an upright position to a collapsed position. The
upper window pane 350 nests between the hook 446 and the
intermediate finger portion 432 in the collapsed position (FIGS. 8
and 16). A pair of opposing tangs 452 are defined at terminal ends
of the main body portion 426. The rigid frame 420 defines a pair of
studs 454 extending generally parallel to the legs 430. The studs
454 are adapted to be received by a complementary pair of openings
460 defined in the strut 338 (FIG. 10). It is appreciated that one
or more studs 454 may be provided on the retaining member 366. In
this way, the retaining member 366 may be precluded from sliding
along the strut 338 in an assembled position.
[0075] The rigid frame 420 further defines a pair of opposing heel
portions 462. The heel portions 462 provide strength at the legs
430 and encourage a secure fit around the strut 338 in an installed
position. The heel portions 462 and, as a result, the legs 430
provide an inward taper to facilitate assembly of the retaining
member 366 around the strut 338. As with the first pair of
retaining members 356, the legs 430 of the second pair of retaining
members 366 provide a degree of flexibility to facilitate assembly
to a strut 338. In this way, the legs 430 flex outwardly as the
retaining member 366 is advanced downwardly (as viewed in FIG. 16)
until the tangs 462 clear the strut 338. The cooperation of the
stud 454 and the interaction of the legs 430 with the strut 338
provide a snap-fit for the retaining member 366. In this way, no
supplemental fasteners are needed.
[0076] With specific reference now to FIGS. 8 and 13, movement of
the upper window pane 350 from the upright position to the
collapsed position will now be described in greater detail. At the
outset, the first pair of retaining members 356 are pulled
outwardly at the hook portions 390 to a position (represented in
phantom line) allowing the upper window pane 350 to clear the first
pair of retaining members 356. Once the upper window pane 350
clears the first pair of retaining members 356, they may be
released to their relaxed position (represented in solid line).
[0077] Next, the upper window pane 350 rotates generally about the
flexible coupling member 376 and is captured by the second pair of
retaining members 366. In one non-limiting example, the second pair
of retaining members 366 may be flexed outwardly (represented in
phantom line) to accept the upper window pane 350 between the hook
portions 446 and the intermediate finger portions 432. The second
pair of retaining members 366 may then be released causing the
upper window pane 350 to nest between the hook portions 446 and the
intermediate finger portions 432 (represented in solid line).
[0078] With specific reference to FIGS. 17-25, a three pane
windshield assembly 470 according to additional features will be
described. For simplicity, the three pane windshield assembly 470
is shown cooperating with the golf car 332 and overhead assembly
336 as described in relation to FIGS. 7-10. As such, similar
reference numerals will be used.
[0079] The three pane windshield assembly 470 includes a first or
upper window pane 472, a second or lower window pane 474, and a
third or intermediate window pane 476. The upper window pane 472 is
secured to the window frame 344 and arranged adjacent to the roof
portion 342. In one non-limiting example, the upper window pane 472
may define a hook 480 along an upper edge for attaining a secure
tolerance fit around the window frame 344 (FIG. 18). Alternatively,
the upper window pane 472 may be secured to the window frame 344 by
way of fasteners (see e.g., FIGS. 1 and 2). The intermediate window
pane 476 is selectively secured to the window frame 344 by way of a
first pair of retaining members 500. The intermediate window pane
476 defines a top curved flange 504 (FIG. 19), a bottom curved
flange 506 and a pair of side edges 510.
[0080] The lower window pane 474 is secured to the window frame 344
and arranged adjacent to the front end 340. In one non-limiting
example, the lower window pane 474 may be secured to the window
frame 344 by way of a second and third pair of retaining members
512 and 514, respectively. The lower window pane 474 defines a top
lateral edge 520, a bottom edge 522, and a pair of side edges 524.
It is appreciated that the bottom edge 522 of the lower window pane
474 may alternatively terminate at the curved portion 346 of the
window frame 344. As a result, the lower window pane 474 may
alternatively define a planar section. As illustrated in FIG. 19,
the top lateral edge 520 defines an upper curved flange. The curved
flange provides additional structural support to the lower window
pane 474.
[0081] A flexible member 376 operably connects the intermediate and
lower window panes 476 and 474, respectively. The flexible member
376 may be attached to the bottom curved flange 506 of the
intermediate window pane 476 and the upper curved flange 520 of the
lower window pane 474. As will be described, the flexible coupling
member 376 is adapted to provide a pivot axis whereby the
intermediate window pane 476 may be moved from an upright position
(FIG. 17) to a collapsed position (FIG. 18). The flexible coupling
member 376 may be formed and coupled to the window assembly 470
consistent with the other flexible members 376 disclosed
herein.
[0082] With specific reference now to FIGS. 20-22, the first and
second pairs of retaining members 500 and 512, respectively, will
be described in greater detail. Each retaining member of the first
and second pair 500 and 512 is equivalent. As such, for simplicity,
a single retaining member 500 is shown in FIGS. 20-22. The
following discussion will be directed to one of the first pair of
retaining members 500 on the front strut 338 shown in FIG. 17,
however, it is appreciated that the same retaining member 500 may
be adapted for use on the other front strut 338 and as either of
the second pair of retaining members 512.
[0083] Similar to the retaining members 356 of FIG. 13, the first
pair of retaining members 500 are formed of a rigid frame 530
having an integrally molded elastomeric body 532 (FIG. 22). In
general, the retaining member 500 defines a main body portion 536
having a central section 540 and a pair of opposing legs 542
collectively defining a U-channel. An intermediate finger 544
extends outboard from one of the legs 542. A hook portion 548
extends outboard from the intermediate finger 544. The intermediate
finger 544 and the hook portion 548 each may define a ramp 550 and
552, respectively, for facilitating cooperation with the upper
window pane 472 when pivoting from a collapsed position to an
upright position. In one non-limiting example, the upper window
pane 472 may nest between the hook 548 and the intermediate finger
544 in the upright position (FIGS. 17 and 22). In another
non-limiting example, the upper window pane 472 may nest between
the intermediate finger portion 544 and a leg 542 in the upright
position (not shown). In yet another non-limiting example, the
intermediate finger portion 544 may be removed from the retaining
member 500 and the window may next between the hook 548 and the leg
542 (not shown).
[0084] A pair of opposing tangs 550 are defined at terminal ends of
the legs 542. The rigid frame defines a pair of studs 558 extending
generally parallel to the legs 542. The studs 558 are adapted to be
received by a complementary pair of openings 560 defined in the
strut (FIG. 19). It is appreciated that one or more studs 550 may
be provided on the retaining member 500. In this way, the retaining
member 500 may be precluded from sliding along the strut 338 in an
assembled position.
[0085] The rigid frame 530 further defines a pair of opposing heel
portions 564. The heel portions 564 provide strength at the legs
542 and encourage a secure fit around the strut 338 in an installed
position. The heel portions 564 and, as a result, the legs 542
provide an inward taper to facilitate assembly of the retaining
member 500 around the strut 338. It is appreciated that the legs
542 of the retaining member 500 provide a degree of flexibility
such that when assembled to a strut 338, the legs 542 flex
outwardly as the retaining member 500 is advanced rightward (as
viewed in FIG. 22) until the tangs 550 clear the strut 338. The
cooperation of the studs 558 and the interaction of the legs 542
with the strut 338 provide a snap-fit for the retaining member 500.
In this way, no supplemental fasteners are needed.
[0086] With reference now to FIGS. 23-25, the third pair of
retaining members 514 will be described. Similar to the retaining
members 356 and 500 of FIGS. 13 and 22, the third pair of retaining
members 514 are formed of a rigid frame 572 having an integrally
molded elastomeric body 574 (FIG. 25).
[0087] For simplicity, a single retaining member 514 is shown in
FIGS. 23-25. The following discussion will be directed to one of
the third pair of retaining members 514 on the front strut 338
shown in FIG. 17, however, it is appreciated that the same
retaining member 514 may be adapted for use on the other front
strut 338.
[0088] The retaining member 514 defines a main body portion 576
having a central section 580 and a pair of opposing legs 582
collectively defining a u-channel. A hook portion 584 extends
outboard from one of the legs 582. Once installed, the retaining
member 514 remains generally static. As such, the lower window pane
474 may nest between the hook 584 and one of the legs 582 in the
upright and collapsed positions (FIGS. 17 and 18). A pair of
opposing tangs 590 are defined at terminal ends of the legs 582.
The rigid frame 572 defines a pair of studs 592 extending generally
parallel to the legs 582. The studs 592 are adapted to be received
by a complementary pair of openings 600 defined in the strut 338
(FIG. 19). It is appreciated that one or more studs 558 may be
provided on the retaining member 514. In this way, the retaining
member 514 may be precluded from sliding along the strut 338 in an
assembled position. The retaining member 514 has the snap fit
characteristics as described with respect to the other retaining
members disclosed herein.
[0089] Returning now to FIGS. 17 and 18, the lower window pane 474
defines tabs 602 adapted to be bound on an upper edge by the third
pair of retaining members 514 and on a lower edge by the second
pair of retaining members 512. As a result, the lower window pane
474 is precluded from advancing vertically along the strut 338.
[0090] The description herein is merely exemplary in nature and,
thus, variations that do not depart from the gist of that which is
described are intended to be within the scope of the disclosure.
Such variations are not to be regarded as a departure from the
spirit and scope of the disclosure.
