[0027] A detailed description of one or more embodiments of the disclosed apparatus and methods is presented herein by way of example and not limitation with reference to the accompanying figures.
[0028] For the purposes of the description herein, the terms "upper", "lower", right, "left", "rear", "front", "vertical", "horizontal" and their derivatives shall relate to the present disclosure as shown in the accompanying drawings. However, it should be understood that the present disclosure may take various alternative orientations. It should also be understood that the specific devices and processes shown in the drawings and described in the following specification are merely exemplary embodiments of the inventive concepts defined in the appended claims. Therefore, unless the claims expressly state otherwise, specific dimensions and other physical characteristics associated with the embodiments disclosed herein should not be considered limiting.
[0029] The present disclosure relates to an apparatus and method for adjusting a window relative to a vehicle door opening, particularly a flush glass arrangement.
[0030] Referring now to the drawings, and in particular to Figure 1-8 , which shows a window regulator 10 for use with a door module 12 of a vehicle. Specifically, the window regulator 10 is a dual-channel or dual-lift window regulator, which means that two guide rails 26 and two corresponding cursors are employed for use with the dual-channel window regulator 10. Optionally, the guide rail 26 is integrally formed with the door module so that the guide rail 26 and the door module 12 are formed as a single unitary structure. Figure 2 and Figure 3 A guide track 26 is shown that is integrally formed with the door module 12. In use, the window regulator 10 and vehicle door module 12 may be secured to the door 14 of a vehicle 16 for moving the window 18 up and down in the direction of arrow 20 (also referred to as the Z direction).
[0031] According to the present disclosure, the window regulator 10 includes a first or forward slider 22 and a second or rearward slider assembly 24. As used herein, the first or forward slider 22 is positioned closer to the front of the vehicle 16 or the front of the door module 12 than the second or rearward slider assembly 24. In addition, the second or rearward slider assembly 24 is positioned closer to the rear of the vehicle 16 or the rear of the door module 12 than the first or forward slider 22. As used herein, a slider refers to a component that is configured to be connected to a vehicle window and travels or slides along a complementary guide track when the window is moved up and down by the window regulator.
[0032] A first or forward cursor 22 and a second or rearward cursor assembly 24 are each slidably received on a respective guide track 26 secured to the door module 12 .
[0033] Now at least reference Figure 4 and Figure 5, the first or forward cursor 22 includes a pair of opposed portions 28 and 30 that are integrally formed as a single piece with the first or forward cursor 22 to form an opening or slot 32, wherein a portion 34 of the window 18 is received in the opening or slot 32. The portion 34 of the window 18 includes an opening 36. To secure the window 18 to the first or forward cursor 22, when the portion 34 of the window 18 is placed in the opening or slot 32, a post or protrusion 38 of the first or forward cursor 22 is received in the opening 36. To allow the post or protrusion 38 of the first or forward cursor 22 to be received in the opening 36, at least one of the portions 28 and 30 can be deflected away from the other of the portions 28 and 30. For example, in one non-limiting embodiment, both portion 30 and portion 28 are formed of a resilient material, such as plastic or its equivalent, so that when portion 28 is moved away from portion 30 to allow portion 34 of window 18 to be inserted into opening or slot 32, it will be biased back to the original unbiased position. Additionally, in one non-limiting embodiment, post 38 extends from one of portions 28 and 30 into opening or slot 32.
[0034] The opening 36 has a height 40 that is generally similar to the diameter or thickness of the post 38 in the "Z" direction, such that when the post 38 is received in the window 18, movement of the window 18 in the "Z" direction is limited. However, the opening 36 is elongated in the "X" direction, such that the length of the opening in the "X" direction is greater than the diameter or thickness of the post 38. This allows the post 38 to slide within the opening 36, which in turn allows the window 18 to move relative to the post 38. Therefore, when the window 18 is secured to the first or forward cursor 22, the first or forward cursor 22 only allows the window 18 to move in one direction (e.g., the "X" direction).
[0035] Now at least reference Figure 4 , 6, 7 and 8, which show a second cursor assembly or a rear cursor assembly 24. The second cursor assembly or the rear cursor assembly 24 includes a cursor body 42, a cursor adapter 44 and a glass bracket 46. The cursor body 42 is configured to be slidably received on a corresponding guide rail 26 fixed to the door module 12. The cursor adapter 44 is fixed to the cursor body 42, and the glass bracket 46 is fixed to the cursor adapter 44. The glass bracket 46 has an elongated opening 48 that receives a portion of the window 18. The glass bracket 46 is fixed to the cursor adapter 44 by a pair of bolts 50, which pass through a pair of openings 52 in the cursor adapter 44 and threadedly engage with a pair of threaded openings 53 in the glass bracket 46. These bolts threadably engage the openings 53 to secure the glass bracket 46 to the cursor adapter 44. Alternatively, the bolts 50 can engage a separate nut (not shown) that is separate from the cursor adapter 44. The opening 52 of the vernier adapter is elongated in the "Z" direction so that movement of the glass support 46 and window 18 can occur in the "Z" direction for adjustment purposes. In contrast, the opening 52 of the vernier body is not elongated in the "X" direction so that movement of the glass support 46 relative to the vernier adapter 44 does not occur in the "X" direction.
[0036] However, the cursor adapter 44 has an opening 54 for receiving a post 56 of the cursor body 42. The opening 54 is elongated in the "X" direction so that the cursor adapter 44 can move relative to the cursor body 42 in the "X" direction when the post 56 is received in the opening 54. In addition, the length of the opening in the "Z" direction is only slightly greater than the width or diameter of the post 56 so that the movement of the cursor adapter 44 relative to the cursor body 42 in the "Z" direction is limited when the post 56 is received in the opening 54. When the post 56 is received in the opening 54, a bolt 57 can be inserted into the threaded opening 59 of the post 56 to secure the cursor body 42 to the cursor adapter 44. For example, the head 61 of the bolt will be larger than the opening 54.
[0037] Also shown is a foam plate 70 that can be inserted between the cursor body 42 and the cursor adapter 44. The plate 70 has an opening 72 that allows the post 56 to pass therethrough. The foam plate 70 provides a sound absorbing function while also preventing portions of the cursor body 42 from contacting the cursor adapter 44.
[0038] In a non-limiting embodiment, the cursor adapter 44 has a shelf or flange portion 72 that is configured to contact a surface portion 74 of the cursor body 42 to limit movement of the post 56 in the Z direction. Furthermore, the surface of the surface portion 74 is configured to slide along the shelf or flange portion 72 in the X direction.
[0039] Thus, since the post 56 can be moved in the "X" direction before the cursor adapter 44 is fixed to the cursor body 42, adjustment in the "X" direction is possible. In addition, since the shaft of the bolt 50 can be moved in the "Z" direction before the glass support 46 is fixed to the cursor assembly 24, adjustment in the "Z" direction is possible.
[0040] This is particularly useful in an embodiment when the second or rearward cursor assembly 24 is positioned closer to the "B" pillar 76 of the vehicle, where adjustment in both the "X" and "Z" directions is required, especially in flush mounted window systems. Additionally, in flush mounted window systems employing dual channel window regulators, the first or forward cursor 22 typically only requires adjustment in the "X" direction.
[0041] However, in another embodiment, the first or forward cursor 22 may be interchanged with the second or backward cursor assembly 24. In other words, the first cursor 22 may be used as a forward or backward cursor, and the second cursor may be used as a backward or forward cursor.
[0042] The term "about" is intended to include the degree of error associated with the measurement of a particular quantity based on the equipment available at the time the application was filed. For example, "about" may include a range of ± 8% or 5%, or 2% of a given value.
[0043] The terms used herein are for the purpose of describing specific embodiments only and are not intended to limit the present disclosure. As used herein, the singular forms "a", "an" and "the" are also intended to include the plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "comprising" and / or "comprise" when used in this specification indicate the presence of stated features, wholes, steps, operations, elements and / or parts, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, parts and / or combinations thereof.
[0044] Although the present disclosure has been described with reference to one or more exemplary embodiments, it will be appreciated by those skilled in the art that various changes may be made and elements thereof may be substituted with equivalents without departing from the scope of the present disclosure. In addition, and without departing from the basic scope of the present disclosure, many modifications may be made to adapt specific situations or materials to the teachings of the present disclosure. Therefore, the present disclosure is not limited to the specific embodiments disclosed as the best examples contemplated for implementing the present disclosure, but the present disclosure will include all embodiments falling within the scope of the claims.
