Description

TECHNICAL FIELD

This invention generally relates to control assemblies useful for operating heavy duty machinery such as construction equipment and, more particularly to an adjustable assembly for adjusting the position of the control members.

Background Art

A variety of control arrangements are currently used in heavy duty machinery such as construction equipment, for example. Depending on the number of functions that a particular machine can perform, the operator is presented with a plurality of control members such as levers that are moveable to effect a desired operation. One challenge that designers and manufacturers face is providing the control members, such as levers, to an operator in positions where the control members are readily accessible in a safe and efficient manner. Ergonomic concerns such as operator fatigue and convenience must play a role in determining the placement of the control members. Additionally, the varying preferences of different operators ideally should be accommodated.

It has been proposed to include control arrangements within heavy duty machinery that have adjustable positions to accommodate the needs and desires of different operators. Two examples are shown in U.S. Pat. No. 5,409,080, which issued on Apr. 25, 1995, and U.S. Pat. No. 4,478,308, which issued on Oct. 23, 1984. In each of those patents, control arrangements having adjustable features are disclosed. In U.S. Pat. No. 5,409,080, an entire console or platform is selectively moveable in a forward or rearward direction to change the position of the console relative to an operator's seat within a tractor. In U.S. Pat. No. 4,478,308, a pivotable arm rests supports a joy stick-style lever so that the lever can be comfortably grasped within the operator's hand.

While such systems have proven useful in some situations, there is a need to accommodate a plurality of control members that are manipulated by a single hand of an operator. This invention provides such an arrangement with an adjustability feature that minimizes operator fatigue, maximizes operator comfort and accommodates a variety of operator preferences.

DISCLOSURE OF THE INVENTION

In general terms, this invention is an adjustable control assembly. A plurality of control members that are independently and selectively manipulable by an operator are provided. A first support supports at least a first one of the control members and the first support is pivotally moveable relative to a base portion about a pivot axis. A second support supports at least a second one of the control members and is pivotally moveable relative to the base portion and the first support about the same pivot axis.

The two supports preferably are pivotable relative to the base and each other so that the plurality of control members can be positioned and spaced apart relative to each other in a chosen position that accommodates a particular operator's preferences. Providing two moveable supports that both are pivotable about a single pivot axis provides a compact and efficient arrangement that is readily adjustable to meet a particular operator's needs.

The various features and advantages of this invention will become apparent from the following description of what is currently considered the best mode of practicing this invention. The drawings that accompany the description can be briefly described as follows.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a perspective, diagrammatic illustration of a control assembly designed according to this invention;

FIG. 2 is a side, elevational view of the embodiment of FIG. 1 illustrating an example proportional size relationship between the assembly and an operator's hand;

FIG. 3 is a partially exploded diagrammatic illustration of the embodiment of FIG. 1; and

FIG. 4 is a top elevational view of a modified version of the embodiment of FIG. 1;

BEST MODE FOR CARRYING OUT THE INVENTION

FIG. 1 illustrates an adjustable control assembly 20 including a base 22 and a plurality of control members 24. A first support plate 28 is pivotably moveable relative to the base 22 about a pivot axis 30. A second support plate 32 is pivotally moveable relative to the base and the first support plate 28 about the same pivot axis 30. As can be appreciated from FIG. 2, by adjusting the angles α and 74, the relative positions of the support plates 28 and 32 are selectively moveable so that the control members 24 can be placed into a variety of orientations.

The preferred embodiment of this invention includes a plurality of control members 24 that have a size and are positioned relative to each other such that they all fit generally within the grasp of a single human hand 60. Of course, this invention has application in situations where control members are necessarily of a larger size and require different spatial relationships.

In the illustrated embodiment, three control member housings 40, 42, 44 are supported by the first support plate 28. Each of the housings 40, 42 and 44 support a control lever 46, 48 and 50, respectively. The control levers 46, 48 and 50 are selectively moveable by an operator to accomplish an adjustment of various machine components, for example. Similarly, the support plate 32 supports a first housing 52 which supports a moveable lever member 54. A second housing 56 and lever 58 are also supported on the second support plate 32.

In situations where the adjustable control assembly 20 is operated by a single hand of an operator (as shown in FIG. 2) it is possible, for example, for the levers 54 and 58 to be moved toward the pivot axis 30 by pressing on them with the medial and lateral side of an operator's palm. The levers 46, 48 and 50 can be moved as desired by manipulating one's fingers. As can be best appreciated from FIG. 2, all of the control member levers generally fit within the grasp of the operator's single hand 60. Since the support plates 28 and 32 are moveable relative to each other about the single pivot axis 30, the spacing and orientation of the control members can be varied to accommodate different operator hand sizes and preferences. The adjustable features of this invention not only accommodate varying operator needs but reduce the possibility for operator fatigue and enhance operator efficiency while using the control assembly 20.

FIG. 3 illustrates more details regarding the preferred arrangement for supporting the support plates 28 and 32 for relative pivoting motion about the pivot axis 30. The base portion 22 preferably includes two end members 64 that support a pivot pin 66, which is disposed along the pivot axis 30. The first support plate 28 includes a first longitudinal edge 68 that is parallel to and adjacent the pivot pin 66. A pair of generally cylindrical projections 70 extend away from the first longitudinal edge 68. Similarly, the second support plate 32 includes a longitudinal edge 72 having generally cylindrical extensions 74. The pivot pin 66 preferably is received through openings defined in the end members 64 and the central openings through the extensions 70 and 74, respectively. A plurality of set screws 76 preferably are received through threaded openings in the extensions 70 and 74.

When the support plates 28 and 32 are interconnected with the pivot pin 66 and received between the end members 64, the longitudinal placement of the portions of the assembly 20 are fixed because the end members 64 preferably are fixed on a console or panel within a heavy duty vehicle, for example.

The invention preferably includes a locking mechanism for locking the support plates 28 and 32 into chosen positions to maintain a desired orientation of the control members 24. In the embodiment of FIG. 3, the set screws 76 provide such a locking mechanism. By tightening the set screws 76 to engage the pivot pin 66, the support plates are fixed so that there is no relative rotation between the pivot pin 66 and support plates 28 and 30. The pivot pin 66 can be fixed relative to the end members 64 in a conventional manner to prevent the pivot pin 66 from rotating relative to the end members 64, thereby locking the assembly 20 into a desired orientation.

An alternative locking mechanism is illustrated in the embodiment of FIG. 4. In this embodiment, a threaded end 78 on the pivot pin 66 is threadedly received within a corresponding threaded opening 80 on one of the end members 64. The end members 64 preferably include teeth members 82 that selectively are interengaged with teeth members 84 on outer (according to the drawing) edges of the extensions 70. Similar teeth members 86 preferably are provided on the inner (according to the drawing) edges of the extensions 70. Corresponding teeth members 88 preferably are provided on adjacent edges of the extensions 74. The teeth members 82 and 84 and 86 and 88, respectively, interengage to maintain a desired orientation of the first and second support plates 28 and 32. The threaded connection between the threaded portion 80 on the end member 64 and the threaded end 78 of the pivot pin 66 provides the ability to selectively compress the overall arrangement so that the interengaging teeth members prevent relative movement between the support plates 28 and 32. In the preferred embodiment, a handle 90 is provided on an end of the pivot pin 66 opposite from the threaded end 78 to accomplish tightening or loosening the engagement of the interengaging teeth members.

The preferred embodiment of this invention provides that the first support plate 28 and the second support plate 32 are both pivotally moveable relative to each other and the base portion 22. An alternative (although not specifically illustrated) embodiment includes one of the support plates being fixed relative to the base portion with the other support plate being pivotably moveable about the pivot axis 30.

Industrial Applicability
