Patent Application
20220127876
This patent disclosure relates generally to a door handle and, more particularly, to a door handle system for an upward acting vehicle cargo door.
Cargo vehicles such as trailers or trucks sometimes use upward acting doors. These doors may be equipped with both interior and exterior door handles to unlatch/unlock the doors and provide something for the operators to hold on to for operation of the door.
Improvements in operation and/or ergonomics of the door handles is always welcome.
The foregoing needs are met to a great extent by embodiments in accordance with the present disclosure, wherein, some embodiments allow for a handle system with both an exterior and interior door handle.
In one aspect, the disclosure describes a door operating system. The system includes: a handle having: loop shaped gripping portion; an attaching portion defining a slot; structure enclosing the slot, the structure defining fastener holes, wherein the slot is defined by the attaching portion and the structure enclosing the slot; a door operating lever located in the slot.
In another aspect, the disclosure describes a method of making a door operating system. The method includes: forming a handle having loop shaped gripping portion and an attaching portion; forming a slot in an attaching portion; enclosing the slot with a structure, the structure defining fastener holes, defining the slot with the attaching portion and the structure enclosing the slot; locating a door operating lever in the slot; and attaching the handle to the operating lever with fasteners located in the fastener holes.
In yet another aspect, the disclosure describes a door operating system. The system includes: a handle having: loop shaped gripping portion; an attaching portion defining a slot; structure enclosing the slot, the structure defining fastener holes, wherein the slot is defined by the attaching portion and the structure enclosing the slot; a door operating lever located in the slot.

It should be noted that the features illustrated in the drawings are not necessarily drawn to scale, and features of one aspect may be employed with other aspects as the skilled artisan would recognize, even if not explicitly stated herein. Descriptions of well-known components and processing techniques may be omitted so as to not unnecessarily obscure the aspects of the disclosure. The examples used herein are intended merely to facilitate an understanding of ways in which the disclosure may be practiced and to further enable those of skill in the art to practice the aspects of the disclosure. Accordingly, the examples and aspects herein should not be construed as limiting the scope of the disclosure, which is defined solely by the appended claims and applicable law. Moreover, it is noted that like reference numerals represent similar parts throughout the several views of the drawings.
The handle assembly 10 includes an interior mounting plate 22 which includes mounting holes 24 for attaching the interior mounting plate 22 to the door 20. A rotating plate 26 is located on the opposite side of the actuating bar 14 then the interior mounting plate 22. A shaft 28 extends from the exterior handle 16. In the FIGS., the shaft 28 is shown to have a square cross-section, but in other embodiments, other shaped shafts 28 may be used. A mounting fastener 30 has a hole 31 corresponding to the shape of the shaft 28 to allow the mounting fastener 30 to slide along the shaft 28 and also rotate when the shaft 28 rotates.
A snap ring 32 is dimensioned to reside in a groove 34 in the mounting fastener 30. In some embodiments, the mounting fastener 30 has two flat sections 36 and two rounded sections 37. As shown, the groove 34 is only in the rounded sections 37, but in other embodiments, there may be a groove 34 in the flat sections 36 and rounded sections 37. In still other embodiments, the mounting fastener 30 may not have flat sections 36, but have some other shape.
A through hole 38 that is dimensioned to allow at least a portion of the mounting fastener 30 to pass through the hole 38 is located in the flat portion 36 in the interior mounting plate 22. The interior mounting plate 22 has a flat portion 36 that can lay flat against a flat portion 39 of the actuation bar 14. An attaching hole 41 is located in the flat portion 39 of the actuation bar 14.
The actuation bar 14, as mentioned above, may have a generally L shaped cross-section but at some lengths it has an I, l or 1 (without the serifs) shaped cross-section. Where the actuation bar 14 has an L shaped cross section, the actuation bar 14 has a first folded over section 40 and a second folded over section 42. The folded over portions 40 and 42 are at right angles from flat portion 39 which is not folded over and has an I (without serifs) shaped cross section. While the term “folded over portion” is used, it should be understood that in other embodiments, the actuation bar 14 may be formed by other means than folding. It could be extruded, comprised of various joined together sections or any other suitable method.
The folded over portions 40 and 42 contain holes 44 and 46 which are cable eyes for attaching cables (not shown) for actuating latches (not shown) to unlatch the door 20 to allow it to move. The operation of the cables to actuate the door 20 and attaching the cables to a handle system is conventional, and known in the art, and will not be explained in detail as it is not relevant to what is claimed. An example of how cables may attach to a handle system and be used to operate a latch system for a door is explained in U.S. Pat. No. 10,526,820 which is incorporated herein by reference in its entirety for reference.
The rotating plate 26 has a flat portion 50. The flat portion 50 has a fastener hole 54 that is shaped to correspond to the shape of the mounting fastener 30 so that when the mounting fastener 30 rotates, the rotating plate 26 will rotate. In the embodiment shown, the fastener hole 52 has flat sides 54 that correspond with the shape of the mounting fastener 30. The rotating plate 26 may be limited in its rotation by a projection 55 on the interior mounting plate 22. The second folded over area 42 may also contact the rotating plate 26 to move, be moved by, or limit movement of the rotating plate 26 when the actuating bar 14 is in certain orientations.
The use of a snap ring 32 on the mounting fastener 30 may provide some advantages over other types of fastening systems. For example, a snap ring 32 and groove 34 on the mounting fastener 30 are advantageous over threads on a nut and threaded mounting fastener because a threaded nut and threaded fastener may loosen or move along the length of the threaded fastener over time. Further, care may need to be taken of how much to tighten a threaded nut on a threaded fastener in order to place the threaded nut at a desired location along the threads of the threaded fastener or at a desired torque level. Such issues are obviated by using a snap ring and groove on the mounting fastener 30.
The handle 12 has a slot 56 for receiving the actuating bar 14. The actuating bar 14 is attached to the handle 12 with fasteners 58. The bosses 60 in the handle 12 and provide reinforcement for the holes in which the fasteners 58 reside.
As shown in
While the disclosure has been described in terms of exemplary aspects, those skilled in the art will recognize that the disclosure can be practiced with modifications in the spirit and scope of the appended claims. These examples given above are merely illustrative and are not meant to be an exhaustive list of all possible designs, aspects, applications or modifications of the disclosure.
