Figure 10 is a fragmentary perspective view of an alternative to the method shown in Sgure 9.
. . . ' Figures 1 to 3 show a moulded window panel assembly 10 having a window pane portion 12 with a . ..._ = _ = , peripheral region 14 and a peripheral edge 16. The window pane portion 12 has a number of passages 12a for hinge, travel control and latch niechanisms for mounting the moulded window panel assembly in the tailgate of a passenger vehicle, for example as shown in figure Ia. A
pi;ripheral support portion 18 is pioulded onto the poripheral region 14. Of eourse, the peripheral support portion 18 may extend along subsfantially tho entire peripheral region 14, of the window pane portion 12, as desired The peripheral support portion 18 includes at least one intemal passage, in this case two interna[ passages.20, which extend along the peripheral region 14 from an entry location shown at 22.for delivering a supply of power and/or fluid to a delivery locatlon shown at 24. A cover plate 24a is shown for covering the delivery locatlon following installation.
15.
In this case, the mouMed wlndow panel assembly 10 has a second entry location shown at 26. This may be ~ ' = -desirable to deliver more than one supply of power or fluid to the delivery location 24. There may, of course, be more than one delivery location 24; if desired. The delivery location is provided for the window wiper unit, whife a seoond delivery location may be provided for another power or fluid consuming device, such as a brake light. As can be seen, the moulded.window panel assembly 10 is a rear window of a vehicle, such as a sport utility as shown in figure Ia,, though other embodiments may involve window panel assemblies for other applications, such as all terrain vehicles, motorcycles and water craft as shown in figtves,at 10b, l0e and IOd in figures lb, lc and ld tEspeatively, as well as windows for residential and commercial buildings, for instance. Furthermore, tl4e window pane portion may be made of polymeric materials other than glass, such as those known in the trade as LEXAN and PLEXIC3LAS5, as well as laminates of glass, plastic and other materials, among others.
Refaring to figure 2, the 'internal passages 20 contain at least one power.cable 28 and it can be seen that HON-WfilCDA . .
the power cable substantially fills the ititernal passage 20, though the power cable 28 may not fill the entire internal passage 20 but rather may simply be loosely contained therein.
Alternatively, the power cable may essentially form the passage. In this case; the conduit portion may be provided by an outer slcin 28a of the power cable 28. In'figare 3, the power cables 28 are joined to a common connector plug 28b to connect with the window wiper unit (not shown).
=
Referring to figure 2, the moulded window panel assembly 10 has an intermediate support portion 30, or otherwise known as a pre-fom strip with a oonduit portion 32 containing the internal passages 20.
Rafierring to the example shown in 8gure. 5, the intermediate support portion 30 inchuies a ohannel section 34 having pair of spaced locating flanges 36 extending from a body 38. The spaced locating flanges 36 engage opposite sides of the window pane portion 12, along its periphery as seen in figare 2, though other configurations for the intermediate support portion 30 may also be employed as desired. In figures l to 3, the body 38 contains the intemal passages 20, though the passage may be formed adjacent the body 38, if desired.
Referring to figure 2, an adhesive layer 40 is located on the body 38 between the spaced locating flanges 36 and the adhesive layer 40 is an-anged to forma bond between the body 38 and the peripheral edge 16. The adhesive layer 40 may be made of a maberial known by the tradename MYLAR or other such materials capable of withshanding the temperattn=es encountered during a plastic moulding process. If desired, the adhesive lay6r may be applied on one or both of'dbe spaced tocating flanges 36 and/or the inner surfaee 38a of the body 38. The adhesive layer 40 may be applied either continuously or at regular or irregular spaced intervals along the length of the body 38. Alternatively, the intertnediate support portion 30 may be formed to establish a relatively snug friction, fit when the intermediate support portion 30 is app6ed to the window pane portion 12. , .25 !n one variation as shown in figure 4, the body 38 has an inner surface 38a which is spaced from the peripheral edge 16 to form an intemal cavity 42 to contain the intemal passages. A power cable may thus be located in the internal cavity 42 or in the internal passages or both, as desired.
HON-WFJCDA
. = t . ' Refecring to figures 6 and 8, the conduit pqrtiort 32 may, if desired, be integrally formed with the qttermediate support portion 30 to contain one or more power cables 28 as sbown in figure 6, or one or moro power cables 28 and/or one more t]uid pipes 46 as shown in figure S. 5 .
Tho moulded window panel assembly 10 may be formed by a number of methods, including by an ipjection moulding (or also known as encapsulation) teclmique, as represenbed 'm figure 9. In one example, the inLermediate support portion 30 is, in advance, moulded with two power cables 28 in situ. An adhesive layer 40 is applied to the inner surfacx 3 ga of the body 38 and the lattsr is applied to the peripheral region 14 of the window pane portion 12.
With the intermediate support portion in place, tlie window pane portion 12 is plaoed in a mould, two mating dies of which are shown at 50, with a mould cavity 52 which is oriented to be adjacent the peripheral region 14.
. ' .
With the window pane portion and the conduit portion in place, a flowable moulding material is delivered to the mould cavity under conditions suffieient to form a peripheral support portion on at least a portion of tbeperipheral ragion and to contain the at least one conduit portion. Aller a suitable setting period, the window panel assembly 10 may then be withdrawn from the mould cavity 52..
If desired, anzngements may be used to protect the power cables 28 and to,seal the mould in the region of the delivery location 24 during the moulding process. For instance, as'shown in figure 10, a prefonaned block 54 may be diinensioned to match the dimensions of the delivery location 24 and be provided with an inner cavity 54a to receive the power cables 28: In this particular exatnple, the mould cavity 52 is enlarged at 52a to acoomn-odate the preformed block 54. Attaaatively, the preforroed block 54 may be shaped to fit in the mould cavity 52 with the need for an enlargement.
. .
While the window paml assembly 10 makes use of an intetmediate support portion, it will be understood HON-WSlCDA
, .
. , that other arrangcments may be used to position in the conduits in position in the=mould cavity. For instance, the cond , iit may be fastened directly to the peripheral edge 16 of the window, such as by the use of glues or adhesi%e materials, clips or other fasteners or the like.
Whilethe present nvention has been deseribed for wbat are presently considered the prefeired ' embodiments, the invention is not so limited. To the contrary, the invention is intended to cover various niodifications and equivalent arrangements incltsded within the spirit sad scope of the appended claims.

. . . ' Figures 1 to 3 show a moulded window panel assembly 10 having a window pane portion 12 with a . ..._ = _ = , peripheral region 14 and a peripheral edge 16. The window pane portion 12 has a number of passages 12a for hinge, travel control and latch niechanisms for mounting the moulded window panel assembly in the tailgate of a passenger vehicle, for example as shown in figure Ia. A
pi;ripheral support portion 18 is pioulded onto the poripheral region 14. Of eourse, the peripheral support portion 18 may extend along subsfantially tho entire peripheral region 14, of the window pane portion 12, as desired The peripheral support portion 18 includes at least one intemal passage, in this case two interna[ passages.20, which extend along the peripheral region 14 from an entry location shown at 22.for delivering a supply of power and/or fluid to a delivery locatlon shown at 24. A cover plate 24a is shown for covering the delivery locatlon following installation.
15.
In this case, the mouMed wlndow panel assembly 10 has a second entry location shown at 26. This may be ~ ' = -desirable to deliver more than one supply of power or fluid to the delivery location 24. There may, of course, be more than one delivery location 24; if desired. The delivery location is provided for the window wiper unit, whife a seoond delivery location may be provided for another power or fluid consuming device, such as a brake light. As can be seen, the moulded.window panel assembly 10 is a rear window of a vehicle, such as a sport utility as shown in figure Ia,, though other embodiments may involve window panel assemblies for other applications, such as all terrain vehicles, motorcycles and water craft as shown in figtves,at 10b, l0e and IOd in figures lb, lc and ld tEspeatively, as well as windows for residential and commercial buildings, for instance. Furthermore, tl4e window pane portion may be made of polymeric materials other than glass, such as those known in the trade as LEXAN and PLEXIC3LAS5, as well as laminates of glass, plastic and other materials, among others.
Refaring to figure 2, the 'internal passages 20 contain at least one power.cable 28 and it can be seen that HON-WfilCDA . .
the power cable substantially fills the ititernal passage 20, though the power cable 28 may not fill the entire internal passage 20 but rather may simply be loosely contained therein.
Alternatively, the power cable may essentially form the passage. In this case; the conduit portion may be provided by an outer slcin 28a of the power cable 28. In'figare 3, the power cables 28 are joined to a common connector plug 28b to connect with the window wiper unit (not shown).
=
Referring to figure 2, the moulded window panel assembly 10 has an intermediate support portion 30, or otherwise known as a pre-fom strip with a oonduit portion 32 containing the internal passages 20.
Rafierring to the example shown in 8gure. 5, the intermediate support portion 30 inchuies a ohannel section 34 having pair of spaced locating flanges 36 extending from a body 38. The spaced locating flanges 36 engage opposite sides of the window pane portion 12, along its periphery as seen in figare 2, though other configurations for the intermediate support portion 30 may also be employed as desired. In figures l to 3, the body 38 contains the intemal passages 20, though the passage may be formed adjacent the body 38, if desired.
Referring to figure 2, an adhesive layer 40 is located on the body 38 between the spaced locating flanges 36 and the adhesive layer 40 is an-anged to forma bond between the body 38 and the peripheral edge 16. The adhesive layer 40 may be made of a maberial known by the tradename MYLAR or other such materials capable of withshanding the temperattn=es encountered during a plastic moulding process. If desired, the adhesive lay6r may be applied on one or both of'dbe spaced tocating flanges 36 and/or the inner surfaee 38a of the body 38. The adhesive layer 40 may be applied either continuously or at regular or irregular spaced intervals along the length of the body 38. Alternatively, the intertnediate support portion 30 may be formed to establish a relatively snug friction, fit when the intermediate support portion 30 is app6ed to the window pane portion 12. , .25 !n one variation as shown in figure 4, the body 38 has an inner surface 38a which is spaced from the peripheral edge 16 to form an intemal cavity 42 to contain the intemal passages. A power cable may thus be located in the internal cavity 42 or in the internal passages or both, as desired.
HON-WFJCDA
. = t . ' Refecring to figures 6 and 8, the conduit pqrtiort 32 may, if desired, be integrally formed with the qttermediate support portion 30 to contain one or more power cables 28 as sbown in figure 6, or one or moro power cables 28 and/or one more t]uid pipes 46 as shown in figure S. 5 .
Tho moulded window panel assembly 10 may be formed by a number of methods, including by an ipjection moulding (or also known as encapsulation) teclmique, as represenbed 'm figure 9. In one example, the inLermediate support portion 30 is, in advance, moulded with two power cables 28 in situ. An adhesive layer 40 is applied to the inner surfacx 3 ga of the body 38 and the lattsr is applied to the peripheral region 14 of the window pane portion 12.
With the intermediate support portion in place, tlie window pane portion 12 is plaoed in a mould, two mating dies of which are shown at 50, with a mould cavity 52 which is oriented to be adjacent the peripheral region 14.
. ' .
With the window pane portion and the conduit portion in place, a flowable moulding material is delivered to the mould cavity under conditions suffieient to form a peripheral support portion on at least a portion of tbeperipheral ragion and to contain the at least one conduit portion. Aller a suitable setting period, the window panel assembly 10 may then be withdrawn from the mould cavity 52..
If desired, anzngements may be used to protect the power cables 28 and to,seal the mould in the region of the delivery location 24 during the moulding process. For instance, as'shown in figure 10, a prefonaned block 54 may be diinensioned to match the dimensions of the delivery location 24 and be provided with an inner cavity 54a to receive the power cables 28: In this particular exatnple, the mould cavity 52 is enlarged at 52a to acoomn-odate the preformed block 54. Attaaatively, the preforroed block 54 may be shaped to fit in the mould cavity 52 with the need for an enlargement.
. .
While the window paml assembly 10 makes use of an intetmediate support portion, it will be understood HON-WSlCDA
, .
. , that other arrangcments may be used to position in the conduits in position in the=mould cavity. For instance, the cond , iit may be fastened directly to the peripheral edge 16 of the window, such as by the use of glues or adhesi%e materials, clips or other fasteners or the like.
