DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to the various figures, there is shown a transit window assembly 10 for a vehicle. The transit window assembly 10 includes a panel 15. The panel 15 may include various structures such as a glass sheet, plastic or other acrylic sheet, or a metal panel or other material. A support frame 20 is attached to the panel 15. A base mount 25 is removably attached to the support frame 20. A mounting frame 30 is attached to the vehicle. The base mount 25 is linked to the mounting frame 30. A seal 35 is positioned about the base mount 25 and contacts the panel 15 continuously sealing between the base mount 25 and the panel 15. The base mount 25 may be linked to the mounting frame 30 through an intermediate structure such as pivoting structures 95 or may be directly linked to the mounting frame 30, as will be discussed in more detail below.

In one aspect, a rigid linkage 37 removably connects the base mount 25 to the support frame 20. The linkage 37 includes a u-shaped body 40 having a first leg 45 that is removably attached to the base mount 25 and a second leg 50 that is received in a slot 55 defined in the support frame 20. As can be seen in FIGS. 1 and 2, the support frame 20 includes a trough section 60 that receives an adhesive attaching the support frame 20 to the panel 15. The support frame 20 also includes a first leg portion 65 that extends from the trough section 60 and a second leg portion 70 that extends at an angle from the first leg portion 65 defining the slot 55. The linkage 37 includes an indentation 75 formed therein that receives a fastener 80 removably attaching the linkage 37 to the base mount 25. In one aspect, the indentation 75 may be formed at an angle to assist in decoupling the linkage 37 and the base mount 25. In this manner the fastener 80 may be removed without obstruction by structures within a vehicle such as seats or the like.

In one aspect, the support frame 20 includes a positioning datum 85 aligning a glazing attaching the panel 15 to the support frame 20. In one aspect, the second leg portion 70 includes a third leg portion 90 that extends at an angle from the second leg portion 70. The third leg portion 90 contacts the base mount 25 and linkage 37 aligning the panel 15 to the support frame 20 and providing a datum as described above.

In one aspect, as best shown in FIG. 9 the support frame 20 may include a plurality of discontinuous components 22 that are linear. The plurality of discontinuous components 22 are separate components and not formed in one piece. The plurality of linear components 22 may be positioned and attached to the panel 15 along the straight portions of the panel boundary. In this manner, the support frame 20 may be easily manufactured without the need for forming curves or shapes that correspond to a complicated shape of the panel 15. Additionally, the support frame 20 may be easily positioned and attached along the straight portions of the panel 15. The seal 35 attached to the base mount 25 allows for the continuous seal of the panel 15 and base mount 25 even though the support frame 20 is discontinuous.

Again referring to FIG. 1, there is shown a transit window assembly 10 that is an egress assembly wherein the base mount 25 is coupled to pivoting structures 95 that are linked to the mounting frame 30. In one aspect, the egress window may be pivotal such that the panel 15 can be opened allowing occupants within a vehicle to exit the vehicle. In one aspect, the base mount 25 and the mounting frame 30 include pivoting structures 95 allowing pivotal movement of the panel 15.

Again referring to FIG. 1, the egress window assembly 10 may include additional seals such as a secondary seal 100 between the mounting frame 30 and the panel 15, as well as another seal 105 between the mounting frame 30 and the base mount 25. In this manner various components of the transit window assembly 10 remained sealed.

Various types of egress windows as disclosed in FIGS. 3-5 may be utilized. In one aspect the egress window may include a latching structure 110 that allows the egress window to be opened and closed by an occupant of the vehicle. Various latching structures may be utilized, such as handles, buttons or any other latching structure. Various shapes and structures of the panel 15 are shown in FIGS. 3-5. In one aspect, the egress window assembly may include a full panel, a destination type panel, or a transom type panel, as shown in FIGS. 3, 4 and 5 respectively.

Referring to FIG. 2, there is shown a transit window assembly 10 for a non egress window assembly. As with the previously described egress transit window assembly 10 of FIG. 1, there is disclosed a panel 15 and a support frame 20 attached to the panel 15. A base mount 25 is provided with the base mount 25 linked to a mounting frame 30 that is connected to the vehicle. In one aspect the base mount is directly linked to the mounting frame 30 as shown in the figure. As previously described, a seal 35 is positioned about the base mount 25 and contacts the panel 15 continuously sealing between the base mount 25 and the panel 15. Additionally, as previously described, a rigid linkage 37 removably connects the base mount 25 to the support frame 20.

As with the previously described egress window assembly, various types of non egress window assemblies may be utilized. For example, as shown in FIG. 6, a full panel non egress window assembly may be utilized. Additionally, as shown in FIGS. 7 and 8, destination type non egress window assemblies and transom type non egress window assemblies may also be utilized.

The transit window assembly 10 provides a serviceable flush window assembly for use in transit applications such as in a bus, train, or other types of vehicles. The serviceable transit window assembly 10 provides for a simplified procedure when replacing the panel 15 due to damage such as graffiti, breakage or abuse by an occupant of the vehicle. In one aspect, a party servicing the vehicle may easily remove the panel 15 by removing the fastener 80 that passes through the rigid linkage 37 and attaches the base mount 25 to the support frame 20. The linkage 37 may then be lifted or removed from the slot 55 formed in the support frame 20 allowing the panel 15 and support frame 20 to be easily removed from a window opening. A replacement panel 15 attached to another support frame 20 may easily be reattached to the base mount 25 by coupling and positioning the support frame 20 utilizing the rigid linkage 37 that is then attached to the base mount 25 utilizing the fastener 80 that passes through the rigid linkage 37. The seal 35 that is attached to the base mount 25 contacts the panel 15 as the support frame 20 is attached to the base mount and seals the panel 15 and base mount 25. In this manner, a simplified procedure is provided in which a seal 35 does not need to be replaced in a complicated assembly such as when a seal is positioned between or attached to other components of a window assembly.

The invention has been described in an illustrative manner. It is to be understood that the terminology which has been used is intended to be in the nature of words of description rather than limitation. Many modifications and variations of the invention are possible in light of the above teachings. Therefore, within the scope of the appended claims, the invention may be practiced other than as specifically described.
