Device Mounting System for Cab

Abstract

A system for mounting a device such as a display device (e.g., a monitor) inside a cab of a utility vehicle having generally vertically extending pillars supporting a cab roof structure. The system has one or more first support elements designed to extend generally horizontally between two pillars and one or more second support elements designed to extend generally vertically from the roof structure to support the first element or elements in position between the pillars. Attachment mechanisms are carried on one or more of the support elements for supporting one or more display devices or other devices.

DETAILED DESCRIPTION

[0036] FIGS. 1 and 2 show diagrammatic representations of a tractor cab 10, which has four corner posts or pillars 11 supporting a roof structure 12 above a cab floor 13. In other embodiments, the cab may have more than four pillars supporting the roof structure.

[0037] A mounting system 14 for a display device or other device 15 has a first generally horizontally extending support element 16 designed to extend between two of the pillars 11 and a second generally vertically extending support element 17 which is designed to extend between the roof structure 12 and a mid-portion of the first support element 16.

[0038] In the example shown, the pillars 11 each have a track 18 secured to their inwardly facing surface to which first fasteners in the form of clamps 19 on the ends of the first support element 16 can be secured. Similarly, the second support element 17 has second fasteners in the form of clamps 20a, 20b on its upper and lower ends, which can be respectively secured to a track 21 secured to the roof structure and to a track 16a secured the first support element 16 (See FIG. 2).

[0039] As can be seen from detail 1A of FIG. 1, the track 21 can be orientated vertically or horizontally on the roof structure, but extends lengthways in a direction between the pillars 11 to which the first support element 16 is mounted.

[0040] Details of one form of fastener suitable for use as clamps 19, 20a and 20b are shown in FIGS. 3 and 4. The fastener or clamp 19, 20a and 20b has a main body 22 which slides along track 16a, 18, or 21 which has raised rails 23 extending its edges. The body has flanges 24 which engage and extend behind rails 23 and can be held in a fixed position on the track by tightening a first clamping arrangement or system in the form of clamping screws 26 to bring the ends 25 of the screws into contact with the base 27 of the track.

[0041] An arm 28 which is mounted on a swivel plate 29 via a pin 33 (see FIG. 2) for pivoting about an axis 30 as indicated by arrow P (see FIG. 3). The swivel plate 29 is in turn mounted on the body 22 by second clamping arrangement or system in the form of a clamping screw 31 so that the angle of the arm 28 relative to body 22 can pivot about axis 32 of screw 31 as indicated by arrow S.

[0042] The arm 28 has a slot 34 through which the arm can be attached to the support element 16, 17 by winged screws 35 (see FIGS. 2 and 5). The first support element 16 is provided with a clamp 19 at either end for engagement with respective pillars 11 as shown in FIGS. 1 and 2.

[0043] As shown diagrammatically in FIG. 1, the lower end of the generally vertical support element 17 is secured to the mid-portion of the first element 16 by clamp 20b, which can be of the same form as clamp 19 described above with the first element having its track 16a orientated on its edge with the track rails 23 one above the other.

[0044] As will be appreciated, the effective length of the first and second support elements can be adjusted using the position of the winged screws 35 in the slots 34 of the arms 28 to fit a range of cabs. Also, the length of the first and second support elements can be used to force the clamps towards their respective tracks 16a, 18, or 21 to assist in maintaining the clamps in contact with their tracks. The first and second support elements 16, 17 can also be telescopic to further assist in making the mounting system more versatile in fitting a range of different tractor cabs.

[0045] Also, if necessary, due to cab geometry such as curved pillars, the clamps 19 can be modified as shown in FIGS. 6 and 7, in which the swivel plate 29, a cooperating portion 22 of the main body of the clamp, and a clamping nut 36 are all domed to allow further freedom of movement of the arm 28 relative to the body 22 of the clamp as indicated by arrow T.

[0046] The display device 15 can be mounted on either of the first or second support elements 16 and 17 of the mounting system by a suitable mounting bracket or clip arrangement 15a, also referred to as an attachment apparatus. One suitable mounting bracket is shown in FIGS. 8 and 9, in which bracket 40 has a support plate 41 for direct support of the display device and which is in turn supported by an articulated arm 42. The articulated arm 42 has a clamp 43 at the end opposite the support plate 41 for mounting to a support element 16, 17. The clamp 43 may have flanges 44 that engage rails 45 of a track 46 on the support element 16, 17. The clamp is secured in position on the track by a clamping screw 47, which engages the base 48 of the track 46 in a manner similar to that as previously described with reference to the clamping screw 26 of FIGS. 3 and 4. A track 46 for the mounting bracket 40 can be provided on either or both of the support elements 16, 17. Where the mounting bracket 40 is mounted to the first support element 16, the clamp 43 can be mounted to the track 16a on the first support element 16, which takes the place of the track 46.

[0047] Although the tracks 16a, 18, 21, 46 are described above as separate components which are mounted on the pillars, roof structure, or support elements, these tracks could be formed integrally with pillars, roof structure, or support elements.

[0048] The use of tracks might be avoided completely by, for example, providing spaced threaded apertures 50 along the pillars, roof structure, or other parts of the cab into which the clamping screws 26 can be screwed to secure the main bodies 22 of clamps 19 in the required positions as shown in FIGS. 10 and 11.

[0049] If necessary, the first support element 16 can be inclined significantly relative to the horizontal, and the mounting system of the present invention provides a great deal of freedom in the positioning of the mounted display device or similar device.

[0050] Also, although the embodiment described in detail above has only one horizontal first support element 16 and one vertical second support element 17 secured to the mid-portion of the first element, other configurations include more than one first and/or second support element. For example, several vertical second support elements might support one horizontal support element, or two first support elements might be joined end to end with a vertical second support element supporting the first support elements at their junction. These more complex configurations enable the mounting system to support more weight. Furthermore, though embodiments of the invention are described for use in a cab of an agricultural tractor, the mounting system can be adapted for use in other utility vehicles having a similar cab structure including, without limitation: other agricultural vehicles, construction vehicles such as diggers, excavators, or the like, and mobile machines.
