Abstract
Description
- The present invention relates generally to agricultural machines having moveable panels to provide access to internal areas, and, more particularly to a hinge mechanism that enables easy removal of the access panel in one position while preventing removal of the panel while in a second position.
- Many harvesting machines and headers employ movable hoods or panels to provide access to the machine internals. These panels are typically hingedly connected to provide convenient access for routine inspections. Oftentimes the panels are removable to afford even greater access to the machine internals, such as for component service or replacement. The conventional method for panel removal involves detaching the hinges on which the panel swings from the machine structure, typically secured by bolted connections. Panel removal thus requires a time-consuming removal of multiple fasteners. Furthermore, loose fasteners are easily misplaced which adds further complication to reinstalling the panels.
- It would be advantageous to provide an improved connection for an access panel on an agricultural machine that would permit hinged opening and closing of the panel for routine access as well as allow the panel to be easily removed from the machine without requiring tools for removal.
- Accordingly, the present invention, in any of the embodiments described herein, may provide one or more of the following advantages:
- It is an object of the present invention to provide a self-locking hinge for movable panels used on agricultural machines that enable easy, tool-free removal of the panel from the machine. A machine mounted receptacle slidingly receives an insert. A hinge having a fixed and a movable portion is connected to the insert. A locking retainer is connected to the movable portion and configured to engage an opening in the receptacle as the movable portion is moved toward a first position. Engagement of the locking retainer and the opening, caused when moving the hinge toward the first position precludes sliding movement of the insert portion. Moving the hinge in a direction opposite of the first direction disengages the locking retainer from the opening and permits sliding movement of the insert relative to the receptacle, including removal of the insert from the receptacle which detaches the panel from the machine.
- It is a further object of the present invention to provide a self-locking hinge for movable panels used on agricultural machines that replaces a conventional movable panel hinge and permits conventional hinged movement of the panel. A conventional hinge is connected to an insert which is selectively disposed in a receptacle fixed to the machine chassis. The hinge permits movement of the panel in generally opposing first and second directions without requiring that the insert be slidingly disengaged from the receptacle.
- It is a further object of the present invention to provide a self-locking hinge for movable panels used on agricultural machines that includes a machine mounted receptacle configured to slidingly receive an insert. A hinge having a fixed and a movable portion is connected to the insert. A locking retainer is connected to the movable portion and configured to engage an opening in the receptacle as the movable portion is moved toward a first position. The locking retainer includes an arcuate surface configured to engage an edge of the opening to prevent the insert from being slidingly removed from the receptacle. The arcuate surface is eccentrically arranged about the hinge pivot so that the insert is slidingly moved to a desired position as the hinge is pivoted toward the first position by interaction between the arcuate surface and the edge.
- It is a still further object of the present invention to provide a self-locking hinge for movable panels used on agricultural machines that is durable in construction, inexpensive of manufacture, carefree of maintenance, easily assembled, and simple and effective to use.
- These and other objects are achieved by providing a self-locking hinge for movable panels used on agricultural machines includes a machine mounted receptacle configured to slidingly receive an insert along an receiving axis. A hinge having a fixed and a movable portion and pivot axis transverse to the receiving axis is connected to the insert. A locking retainer is connected to the movable portion and configured to engage an opening in the receptacle as the movable portion is moved toward a first position corresponding with panel closure. Engagement of the locking retainer in the opening, caused when the hinge is moved toward the first position, precludes movement of the insert portion along the receiving axis. Moving the hinge in a direction opposite of the first direction disengages the locking retainer from the opening and permits sliding movement of the insert relative to the receptacle. The locking retainer further includes an arcuate surface configured to engage an edge of the opening which may further be eccentrically arranged about the hinge axis to enable the locking retainer to move the insert into a desired position as the hinge is moved toward the first position.
- The advantages of this invention will be apparent upon consideration of the following detailed disclosure of the invention, especially when taken in conjunction with the accompanying drawings wherein:
-
FIG. 1 is a side view of an agricultural harvesting machine, which is a combine, including a header on which the present invention is useful; -

Also, any reference herein to the terms “left” or “right” are used as a matter of mere convenience, and are determined by standing at the rear of the machine facing in its normal direction of travel. Likewise, “forward” and “rearward” are determined by the normal direction of travel. “Upward” and “downward” orientations are relative to the ground or operating surface as are any references to “horizontal” or “vertical” planes. Furthermore, the various components shown or described herein for any specific application of this invention can be varied or altered as anticipated by this invention and the practice of a specific application of any element may already be widely known or used in the art by persons skilled in the art and each will likewise not therefore be discussed in significant detail. When referring to the figures, like parts are numbered the same in all of the figures.
- Referring to the figures,
FIG. 1 illustrates a conventional agricultural machine, acrop harvester 10 in this instance, having a forwardly mountedheader 15 for processing a standing crop as the harvester moves across a field. It is common to provide one or moremoveable panels 20 at various locations on the header as part of an overall protective shroud for the header. Thepanels 20 are conventionally hinge-connected to the machine chassis and may be positioned in a first position (closed,panel 20 a inFIG. 1 ) to contain crop and other debris within the machine, prevent the expulsion debris made airborne by impact with a rotary cutter, and/or generally create, in conjunction with the remainder of the shroud, a boundary separating the inner mechanism of the machine from exterior locations where people may be present. Moving the panels to a second position (opened,panel 20 b inFIG. 1 ) allows an individual to gain access to the interior of the machine to permit access for maintenance or repair of the machine internals. The panels may include latches to retain them in the closed position or they may be oriented so that gravity maintains them in the closed position. Such arrangements are well known in the art. - It is often necessary to detach the
moveable panels 20 from the machine to provide additional access for certain repairs to or replacement of the machine internals. The present invention reduces the effort necessary to remove the panels from the machine by providing a self-locking hinge assembly 30 that connects the panels to the machine chassis. Multiple mechanisms may be used dependent upon the number and size of the moveable panels on the machine. - Referring now to
FIGS. 2-6 , the self-locking hinge assembly 30 includes areceiver 32 attached to themachine chassis 17 and aninsert 34. Thereceiver 32 andinsert 34 are configured to be engaged and disengaged by movement along areceiving axis 110. In the embodiment illustrated, thereceiver 32 includes awall member 322 surrounding aninterior space 328 having a generally rectangular cross-section area. Theinsert 34 is an elongate member configured with a generally rectangular exterior cross-section area that may be slidingly received within theinterior space 328. The relative sizing of the cross sectional areas is sufficiently similar to limiting lateral movement between theinsert 34 and thereceiver 32 while permitting sliding movement along thereceiving axis 110. It is also anticipated that the relative orientation and configuration of thereceiver 32 and theinsert 34 could be reversed such that theinsert 34 is externally disposed on thereceiver 32. - The length of the
insert 34 and thereceiver 32 is sufficient to provide a stable interface when theinsert 34 is fully engaged in thereceiver 32, as shown inFIG. 6 . - The self-
locking hinge assembly 30 further includes ahinge 36 having a fixedportion 362 connected to theinsert 34 andmoveable connector 364 pivotally connected thereto by apivot ping 361 or the like. Themoveable connector 364 is pivotable about apivot axis 120 in generally opposing directions between extremes corresponding to first (open) (FIG. 6 ) and second (closed) (FIG. 2 ) positions. Thepivot axis 120 is generally transversely oriented to the receivingaxis 110. Themoveable panel 20 is connected to themoveable connector 364 and thus may also be pivoted between open and closed positions. - Detachment of the
movable panel 20 from themachine 10 requires moving the insert 34 (connected to the panel by the hinge 36) upwardly along the receivingaxis 110 until it disengages from thereceiver 32. Themovable panel 20 may be reconnected to the machine by aligning theinsert 34 with thereceiver 32 and then moving theinsert 34 along the receivingaxis 110 until it is engaged (surrounded by) thereceiver 32. Astop 327 may be provided to prevent theinsert 34 from being inserted too far into thereceiver 32. Engagement of the insert in the receiver to an extreme position could interfere with movement of thepanel 20. - In order to prevent unintended or accidental movement of the insert that could lead to disengagement from the receiver, a locking
assembly 40 is provided which engages the fixed portion, preferably thereceiver 32, when the hinge and panel are in specific positions, ideally corresponding to the panel being in the closed position (FIG. 6 ).Apertures receiver 32 and theinsert 34, the apertures aligning when theinsert 34 is fully engaged in the receiver (FIG. 6 ). A lockingmember 366 is connected at aproximal end 367 to themovable connector 364 or thepanel 20 for movement therewith. The lockingmember 366 includes an generally arc-shapedarcuate surface 365 which may be symmetric with an arc center coinciding with thepivot axis 120 and a cross sectional profile that generally matches the configuration of theapertures member 366 to be extended through the apertures. The lockingmember 366 is aligned so that pivotal movement of the panel/movable connector causes thedistal end 368 to be inserted into theapertures arcuate surface 365, when theinsert 366 is fully engaged and the panel is pivoted toward the closed position. The lockingmember 366 terminates at adistal end 368, the positioning of thedistal end 368 being such that the lockingmember 366 may be fully disengaged from theapertures hinge 30. When the lockingmember 366 is inserted into theapertures insert 34 is prevented from disengagement movement along the receivingaxis 110. - In another embodiment, the length of the
insert 34 is less than the length of the radius of thearcuate surface 365 or similarly configured to preclude interaction with thearcuate surface 365. In this arrangement, only thereceiver 32 requires anaperture 42 into which the lockingmember 366 may be engaged. - In another embodiment, the
arcuate surface 365 is eccentrically arranged about thepivot axis 120 and configured so that the radial distance from thepivot axis 120 toarcuate surface 365 decreases as thehinge 36 pivots toward the closed position. An initial radius R1 is established at a hinge pivot position corresponding to initial contact betweenedge 422 of theaperture 42 and thearcuate surface 365 proximate to thedistal end 368. The radial distance between thepivot axis 120 and thearcuate surface 365 is reduced with continued pivoting movement of thehinge 36 from the initial contact pivot position toward the closed position, at which point the radial separation is shown as R2. As the radial distance is reduced, the lockingmember 366 pulls theinsert 34 more fully into engagement with thereceiver 32 until the closed position is reached. The radial separation from thepivot axis 120 is similar for thearcuate surface 365 and theedge 422 in the closed position.FIG. 6 best illustrates the varying radial separations wherein the initial radius R1, is greater than the final radius R2, corresponding to the pivot position at which the lockingmember 366 is fully engaged and the movable portion has reached the first (closed) position. The configuration provides a secure connection between thehinge 36 and themachine chassis 17 which reduces the likelihood of rattles and other unwanted movement during machine operation. - It will be understood that changes in the details, materials, steps and arrangements of parts which have been described and illustrated to explain the nature of the invention will occur to and may be made by those skilled in the art upon a reading of this disclosure within the principles and scope of the invention. The foregoing description illustrates the preferred embodiment of the invention; however, concepts, as based upon the description, may be employed in other embodiments without departing from the scope of the invention.
