(10) Referring to FIG. 2, a wiper arm holder 30 in accordance with an embodiment of the invention is shown. The holder 30 includes a receiver section 32 and a moveable shaft section 34 having first 36 and second 38 end loops, respectively. The receiver section 32 includes an interior hollow 40 for receiving the shaft section 34. The shaft section 34 is moveable relative to the receiver section 32 to form a telescoping arrangement wherein the shaft section 34 moves in and out of the receiver section 32 in a longitudinal direction 42 thus moving the first 36 and second 38 end loops closer and further away, respectively, from each other. The receiver section 32 also includes a locking mechanism 44 for locking the shaft section 34 in place once the shaft section 34 is located in a desired position. By way of example, the locking mechanism 44 may be a locking collar, clutch lock, cam lock, snap collar, twist lock compression lock arrangement or other known locking mechanism.

(11) Retelling to FIG. 3, an alternate embodiment for the holder 30 is shown. In this embodiment, the shaft section 34 includes a plurality of holes 26 for receiving a pin element 28 that extends through the receiver section 32. In use, the shaft section 34 is moved to a desired position relative to the receiver section 32. The pin element 28 is then positioned through a selected hole 26 corresponding to the desired position thereby locking the shaft section 34 in the desired position.

(12) In yet another embodiment, the receiver section 32 may include a channel section, formed on an exterior surface 46 of the receiver section 32, which receives the shaft section 34. Further, the receiver section 32 may include one or more aligned guide elements, such as wire guides formed on the exterior surface 46, which receive the shaft section 34.

(13) Referring to FIG. 4, a front view of a holder 30 attached to first 48 and second 50 wiper arm assemblies located in an extended position relative to windshield 22 of a motor vehicle is shown. Referring to FIG. 4 in conjunction with FIGS. 2 and 3, the first 36 and second 38 end loops are removeably attached to the first 48 and second 50 wiper arm assemblies, respectively, of a motor vehicle. In particular, the first 36 and second 38 end loops each include an aperture 58 for receiving and removeably attaching a portion of a wiper arm assembly 48, 50 such as an associated wiper arm 12 or wiper blade 14 or a combination thereof. In an embodiment, the first 36 and second 38 end loops are fabricated from a resilient material, such as rubber or an elastomeric material, which stretches and conforms to the shape of a portion of an associated wiper arm assembly 48,50 such as an associated wiper arm 14 or wiper blade 14. For example, the first 36 and second 38 end loops are removeably attached to an associated wiper assembly 48, 50 by inserting an end 56 of a wiper arm 14 into an aperture 58 that is sized smaller than the wiper arm 14. Alternatively, the first 36 and second 38 end loops may be fabricated from a molded material, such as plastic, having an aperture 58 that corresponds to a shape of a portion of the first 48 and second 50 wiper arm assemblies. In another embodiment, the first 36 and second 38 end loops may include a hook and loop fastener (i.e. a Velcro fastener), a strap, clamp device, clasp device or other known attachment method and combinations thereof.

(14) As previously described, the moveable section. 18 may move or snap back in a first direction 24 toward the windshield 22 such that the wiper blade 14 moves from the extended position to the contact position and impacts the windshield 22 with sufficient force so as to damage the windshield 22 and/or the wiper blade 14. Movement to the contact position occurs when the first 48 and second 50 wiper arm assemblies are separated by a first distance 52 as shown in FIG. 4. In accordance with aspects of the invention, the first distance 52 between the first 48 and second 50 wiper arm assemblies may be decreased to a second distance 52A by moving the shaft section 34 into the receiver section 32 in the longitudinal direction 42. Alternatively, the first distance 52 between the first 48 and second 50 wiper arm assemblies may be increased to a third distance 52B by moving the shaft section 34 out of the receiver section 32 in the longitudinal direction 42. In accordance with aspects of the invention, decreasing or increasing the first distance 52 between the first 48 and second 50 wiper arm assemblies to either the first 52A or second 52B distances, respectively, places the wiper arm assemblies 48, 50 under tension in a tension direction 54 substantially transverse to the first direction 24 (see FIG. 1). In particular, placing the first 48 and second 50 wiper arm assemblies under tension holds the first 48 and second 50 wiper arm assemblies in the extended position. This substantially reduces the likelihood that either or both wiper arm assemblies 48, 50 move or snap back toward the windshield 22 thus causing damage of the windshield 22 or wiper arm 14.

(15) FIG. 5 is a partial side view of a motor vehicle which depicts the first 48 and second 50 wiper arm assemblies in the extended position and an alternate embodiment of the holder 30. In this embodiment, the holder 30 includes a support element 60 that is attached to the receiver section 32, for example, of the holder 30 by a hinge element 62. When the wiper blade 14 is in the extended position, a vehicle operator may rotate the support element 60 about the hinge element 62 toward the windshield 22 until the support element 60 contacts or abuts against the windshield 22 in a support position as shown in FIG. 5. In this position, the support element 60 supports the holder 30 and thus the moveable section 18 of the first 48 and second 50 wiper arm assemblies so as to inhibit movement of either or both wiper arm assemblies 48, 50 toward the windshield 22, thus reducing the likelihood of damage to the wiper blade 14 or windshield 22.

(16) FIG. 6 is another view of the holder 30 and support element 60 shown in FIG. 5. As previously described, the receiver section 32 includes the hinge element 62. The hinge element 62 includes a pivot pin 64 that extends through pin supports 66 located on the receiver section 32. The pivot pin 64 also extends through an end 68 of the support element 60 located between the pin supports 66. The support element 60 is rotatable about the pivot pin 64 thus enabling rotation of the support element 60 toward the windshield 22 and away from the windshield 22. The hinge element 62 may be located in any location on the receiver section 32 such as in a central portion of the receiver section 32 or adjacent the end loops 36, 38, thereby locating the support element 32 in close proximity to a wiper arm assembly 48, 50. The support element 60 may also include a rotatable support pad 70 that is rotatable relative to the support element 60 such that the support pad 70 rests against the windshield 22. The support pad 70 may be rotated and adjusted to align with an orientation of the windshield 22 so that substantially all portions of the support pad 70 contact the windshield 22. Further, a portion of the support pad 70 may be fabricated from a material that increases friction between the support pad 70 and the windshield 22, such as a rubberized material, so as to maintain a position of the support pad 70 relative to the windshield 22 to enhance stability of the support element 60 when the support element 60 is in the support position shown in FIG. 5. In addition, more than one support element 60 may be used to support the wiper arm assemblies 48, 50.

(17) While particular embodiments of the present disclosure have been illustrated and described, it would be obvious to those skilled in the art that various other changes and modifications can be made without departing from the spirit and scope of the disclosure. It is therefore intended to cover in the appended claims all such changes and modifications that are within the scope of this disclosure.
