BACKGROUND OF THE INVENTION
The present application is related to vehicle service system consoles, and in particular to a machine vision vehicle wheel alignment service system console with an integrated structure for supporting a vertical post carrying a machine vision sensor cross member.
Vehicle service systems, such as machine vision vehicle wheel alignment systems, generally consist of an operator workstation or console, and a set of associated sensors for acquiring vehicle measurements. For machine vision vehicle wheel alignment systems, the sensors may consist generally of a set of cameras mounted to opposite ends of a cross member in an elevated position on a vertical post secured to the floor. The cameras are oriented such that associated fields of view encompass the left and right sides of a vehicle undergoing a wheel alignment measurement procedure on a lift rack or within a vehicle service bay.
The operator workstation or console provides a structure to organize the various user interface components, such as a keyboard, a mouse, a display unit, and a printer, while containing the associated power supply components, processing system, accessory storage, and necessary electrical cable routing. Typically, the cameras mounted to the cross member are coupled to the processing system by associated electrical cables, necessitating either lengthy cable runs from the location of the vertical post to the workstation or console, or placement of the workstation or console in close proximity to the vertical post. Lengthy cable runs across a shop floor can present a trip hazard, increase clutter, are at risk of being damaged in a vehicle service shop environment, and hence are not ideal. While placement of the operator workstation or console in proximity to a vertical post may reduce the need for lengthy cable runs, the workstation or console may occupy valuable floor space in a prime location adjacent to the column, and/or lead to wasted floor space if the workstation or console cannot be positioned flush against a wall or the vertical post itself.
In some configurations, the vertical post is positioned on, but not affixed to, the workshop floor, and is instead secured along a vertical surface directly to an external side surface of an adjacently disposed operator workstation or console, such as can be seen in the Hawkeye Series HS200CM product sold by Hunter Engineering Company of St. Louis, Mo. Attachment to the external side surface of the operator workstation or console reduced the need for lengthy cable runs, but does not achieve optimal usage of the workshop floor space, as the vertical post remains outside of the housing footprint of the operator workstation or console. If the vertical post is secured to the rear external side surface of the operator workstation or console, the combined assembly cannot be positioned flush against a wall due to the protrusion of the vertical post. Furthermore, attachment of a full height vertical post to an external side surface of an operator workstation or console, which rests on a floor of a vehicle service area, significantly increases the weight the workstation or console, rendering repositioning within the shop environment difficult and potentially dangerous due to an uneven (i.e. top-heavy) distribution of mass.
In another known configuration, the vertical post is bolted to a workshop floor in an appropriate location to provide the associated cameras with the necessary fields of view. A workstation or console unit is then hung directly from the vertical post, at a height appropriate for a service technician, such as seen in the WA series column mount consoles sold by Hunter Engineering Company. With this configuration, the console is suspended above the floor, leaving the workshop floor clear of obstructions and/or electrical cable runs. However, with this type of configuration, the combination of the vertical post and the suspended workstation or console is immobile, as it must remain affixed to the workshop floor for stability.
Accordingly, it would be advantageous to provide an operator workstation or console for use in a vehicle service system, and in particular, a machine vision vehicle wheel alignment service system with an integrated camera support column, which is compact, self-contained, and which can be easily repositioned within a workshop environment. It would be further advantageous to provide such an operator workstation or console with an internal storage volume which is not significantly impacted by internal support structures necessary to secure a vertical post or camera support column carrying a machine vision sensor cross member and associated cameras.
BRIEF SUMMARY OF THE INVENTION
Briefly stated, in a first embodiment, the present disclosure provides a vehicle service system console for use with a machine vision vehicle wheel alignment system. The console consists of a base member which receives and supports a vertical post upon which a machine vision sensor cross member is disposed. Within the base member, a storage volume is defined by left and right peripheral walls, a floor, a rear cover panel, and the underside of an upper work surface atop the base member. The vertical post is received on, and secured to, an internal support structure within the base member, vertically adjacent to the upper work surface. The vertical post passes upward through, and is at least partially enclosed within, a resected portion of the upper work surface. A front surface of the storage volume is defined by one or more doors and sliding drawer faces which provide access to the interior of the console.
In a further embodiment, the vehicle service system console includes a transport platform on which the base member is disposed. The upper surface of the transport platform defines the floor of the base member. A lower surface of the transport platform, spaced from the upper surface to provide a second storage volume, is supported on a set of casters or rollers to facilitate movement of the vehicle service system console across a workshop floor.
In yet another embodiment, the vehicle service system console base member includes left and right storage compartment doors hinged to the external surfaces of the left and right peripheral walls. Each storage compartment door encloses a peripheral storage compartment for the storage of vehicle service system accessories, contained within the footprint of the upper work surface atop the base member.
The foregoing features, and advantages set forth in the present disclosure as well as presently preferred embodiments will become more apparent from the reading of the following description in connection with the accompanying drawings.

DETAILED DESCRIPTION
The following detailed description illustrates the invention by way of example and not by way of limitation. The description enables one skilled in the art to make and use the present disclosure, and describes several embodiments, adaptations, variations, alternatives, and uses of the present disclosure, including what is presently believed to be the best mode of carrying out the present disclosure.
Turning to the Figures, and to FIGS. 1-4 in particular, a machine vision vehicle service system console 100 of the present disclosure is shown generally consisting of a base unit 102 mounted on a transport platform 104, a vertical post 106 extending above the base unit, and a machine vision sensor cross member 108 carried by the vertical post. The base unit include left and right peripheral side walls 110 in a laterally spaced arrangement on the upper surface 112 of the transport platform. A tray member 114 seated on a transverse support plate 116 extending across the top of the peripheral walls defines an upper work surface 115 at the top of the base unit, while the upper surface 112 of the transport platform functions to establish a floor for the base unit. The transport platform preferably 104 includes a lower surface 118 spaced vertically from the upper surface by supporting members 120. The space between the upper and lower surfaces is enclosed, and may optionally include an access 122 such as a sliding drawer or other opening. To facilitate movement of the console within a workshop, a set of casters or rollers 124 may be secured to the underside of the transport platform. Alternatively, the transport platform may be seated directly on a workshop floor, or may rest on supporting feet (not shown). Ideally, the transport platform lower surface defines a footprint which is equal to or slightly greater in dimension than the size of the upper work surface on the base unit, thereby providing a highly stable support for the base unit 102.
The internal space within the base unit 102, enclosed by one or more rear cover panels 126 extending between the left and right peripheral side walls, defines a storage volume which may be configured in a variety of ways. For example, as shown in FIG. 1, the storage volume in the base unit may be accessed via an number of front doors 128 which are hinged to the left and right peripheral side walls, as well as a number of sliding drawers 130 which are carried on drawer tracks 132 secured to the inner surfaces of the left and right peripheral walls, and which each have a suitable drawer front and/or pull handle. The doors and drawer fronts may be made of an opaque material, such as plastic or metal, or may be made of a transparent material such as glass or an acrylic polymer.
Additional storage compartments may optionally be provided on the external surfaces of the left and right peripheral side walls 110, accessed by suitable storage compartment doors 134 hinged to the associated side walls. As best seen in FIG. 2, these storage compartment doors 134 may each be configured to have sufficient thickness to carry internal storage pockets on an inner surface. The dimensions of the tray member 114 defining the upper work surface of the base 102 may be modified as necessary to accommodate any changes in lateral dimensions of the base unit due to the presence or absence of any installed storage compartment doors, such as shown by a comparison of tray member configurations 114a and 114b in FIGS. 5 and 6.
Turning to FIG. 4, a lower end of the vertical post 106 carrying the machine vision sensor cross member 108 is preferably laterally centered relative to the base unit 102, and is secured to the base unit 102 by mounting on an internal support structure 140 within the base unit. The internal support structure 140 consists of a transverse cross member 142 extending between left and right reinforcing flanges 144, which in turn are secured to the inner surfaces of the left and right peripheral walls 110 just below the tray member 114 and upper surface 116. When mounted on the internal support structure 140, the lower end of the vertical post 106 is spaced vertically above the floor 112 of the base unit, and does not significantly intrude into the internal storage volume of the base unit 102. Extending upward through the tray member 114 and the upper work surface 115, the vertical post 106 is recessed at least partially within a footprint defined by the outermost peripheral edges of the upper work surface 115. The tray member 114 may either surround the vertical post as it extends upward, or may include a resected portion 146 through which the vertical post extends, as best seen in FIGS. 3, 7, and 8.
By securing the lower end of the vertical post 106 to the internal support structure 140 of the base unit 102, the vertical post does not extend to the ground or other workshop floor surface on which the console 100 is disposed. Furthermore, the overall length of the vertical post 102 can be reduced by the height of the internal support structure 140 above the ground or other workshop floor surface, thereby reducing the shipping weight, package dimensions, and material requirements for the console 100. Within the vertical post 106, appropriate space may be provide for internally routing electrical cables (not shown) to provide power and communication pathways to the machine vision sensors 200 disposed on the cross member 108. The electrical cables may be routed through opens in the internal support structure of the base unit to connect directly to a power supply unit or processing system 300, such as a personal computer, which are stored within the internal storage volume of the base unit. For cross members 108 which are vertically movable along the vertical post 106, an appropriate sliding or rolling coupling 150 is provided between the cross member and the vertical post. Optionally, counterweights (not shown) are secured for vertical movement along the exterior (or interior volume) of the vertical post, and coupled to the cross member by a suitable arrangement of cables and pulleys. Proper selection and operation of the counterweights facilitates controlled movement and positioning of the machine vision sensor cross member vertically along the vertical post. The counterweights may be configured to be easily removable from quick-release connections, such as hooks, to enable the vertical post to be easily assembled and/or disassembled for shipping.
In a further embodiment, shown in FIGS. 7 and 8, at least one outrigger member 152 is disposed at the rear of either the base unit 102 or the transport platform 104 to provide increased stability. Each outrigger member 152 extends outward from the base unit or transport platform and downward to the workshop floor on which the base or transport platform is disposed. If a single outrigger member is provided, it is preferably laterally aligned with the vertical axis of the vertical post 106, extending perpendicularly outward from the base unit or transport platform and downward to the workshop floor. If multiple outrigger members 152 are provided, they are preferably spaced symmetrically about the lateral centerline of the base unit or the transport platform if the vertical post is disposed on the lateral centerline, or are symmetrically spaced relative to the vertical axis of the vertical post. Each outrigger member 152 functions to increase the stability of the machine vision vehicle service system console 100, particularly when the machine vision sensor cross member 108 is vertically positioned near the upper portion of the vertical post 106. Accordingly it will be understood by one of ordinary skill in the art that the outriggers need not be aligned perpendicular relative to the base unit or transport platform, but may be angularly aligned relative there to.
Each outrigger member 152 may be permanently or temporarily secured to the base or transport platform by either a rigid connection, a sliding connection, or a pivoting connection. For some circumstances, such as during transport of the machine vision vehicle service system console 100, it may be preferable to remove any installed outrigger members 152. Alternatively, if a sliding connection to the outrigger members is provided, they may be retracted along the sliding connection towards the base unit or transport platform to reduce the overall footprint of the machine vision vehicle service system console. Similarly, if a pivoting connection to the outrigger members is provided, they may be pivoted laterally towards or against the adjacent surfaces of the base unit or transport platform to reduce the overall footprint. Alternatively, with an appropriate pivoting coupling, the outrigger members may be pivoted about a longitudinal axis, to be rotated upward away from the workshop floor surface during transport or storage.
The machine vision vehicle service system console 100 of the present disclosure provides several improvements over current console configurations. By supporting the vertical post from an internal structure 140 within the base unit 102, the console reduces the material requires for the vertical post 106, and eliminates the need for the vertical post to either rest directly on a work shop floor or be secured to a work shop floor. With the vertical post at least partially enclosed within a footprint defined by the outermost peripheral edges of the upper work surface 114, the console may be positioned in close proximity to, or abut against, a wall of the work shop, avoiding wasted space and/or the need to route electrical cables between a vertical post and a remotely located console. Placement of the internal support structure 140 supporting the vertical post at a location within the base unit 102 which is adjacent to the tray member 115 and upper work surface 114, the loss of space within the internal storage volume of the base unit 102 is reduced relative to designs which extend the vertical post down to a work shop floor surface. Finally, the placement of casters or rollers 124 on the lower surface 118 of the transport platform 104 allows the console 100, including the vertical post 106 and machine vision sensor cross member 108 to be transported from one location to another within a work shop environment without requiring structural changes, unbolting of components, or disassembly of the vertical post 106.
As various changes could be made in the above constructions without departing from the scope of the disclosure, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
