Description

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority from U.S. Provisional Patent Application Ser. No. 60/684,926 filed May 26, 2005 and is incorporated herein by reference.

BACKGROUND OF THE INVENTION

The present invention relates to vehicle seating and, more particularly, to a passenger seat or a second seat to be attached to a lawn and garden tractor.
Modern lawn and garden tractors are generally designed as single occupant vehicles with a seat for the driver only; however, it is sometimes desirable for a passenger to also ride on the tractor. For example, it may be desirable for an instructor to ride along with a first time driver of a particular type of tractor. Alternatively, it might be convenient for a child to ride along with a parent who is operating the tractor so that the parent can be assured of the child's whereabouts.
Existing, conventional lawn and garden tractors do not provide seats for extra riders. Thus, the rider must assume a crouched position on the tractor to avoid interfering with the driver or blocking his view. Such a position is usually unsafe, as well as uncomfortable and unsteady. Since lawn and garden tractors can be driven over rough terrain, such a position can also be hazardous to the rider and to the driver, if the rider should be thrown off balance on the tractor.
In view of the foregoing, there is a need for a seating provision or attachment which allows a rider on a lawn and garden tractor to sit in a secure, comfortable position without causing interference to the driver and which can be stowed when not needed.

DETAILED DESCRIPTION OF THE INVENTION

It should, of course, be understood that the description and drawing herein are merely illustrative and that various modifications and changes can be made in the structures disclosed without departing from the scope of the invention.
With reference now to FIG. 1, a lawn and garden tractor A is shown with a passenger seat extension assembly B in accordance with a first embodiment of the present invention attached to a rear portion of the tractor. Certain components of the tractor will be mentioned to provide the context. The passenger seat is constructed so that it mounts behind the driver's seat provided for the tractor driver or operator. The tractor is constructed with a bottom floor plate or deck. Typically, the tractor has a drive shaft from the engine in front back to a rear axle which connects to the left and right with a hump in the floorboard. The hump houses the differential for the rear wheels. The rearwheels (not shown) are arranged to the left and right of the operator seat and are enclosed in appropriate fenders to the left and right of the driver. The fenders are mounted to the left and right of the driver. Collectively, these components form the tractor A.
With reference now to FIGS. 2 and 3, the passenger seat assembly B includes a passenger seat extension 10 which generally has a mounting plate 12 and an extension member 14 for supporting at least one seat S. The seat S includes a cushion and a seat belt. The extension member is releasably attached to the mounting plate and extends away from a rear frame 16 of the tractor A. The extension member 14 serves to provide spacing or distance D between the seat S and the rear portion of the tractor. The distance D can vary from about 12 inches to 18 inches or more, and allows the passenger to easily enter and exit the seat.
Referring to FIG. 3, the mounting plate 12 includes four spaced apart mounting holes 19 and a connecting member 20 (FIG. 4) extending generally normal from the mounting plate. The mounting plate is secured to the rear frame of the tractor by conventional fasteners, such as screws or bolts 21 and nuts, the fasteners extending through corresponding openings located in the frame of the tractor and the mounting holes 19 of the mounting plate. In operation, the mounting plate 12 is attached easily because the only connectors utilized are the fasteners 21. They are connected in a rear location so they are out of harm's way, and they are also connected so they can connect through permanently made holes in the rear frame without fear of rusting out that region. Attachment is easily achieved with suitable threaded fasteners. Removal is equally easy and is accomplished in the same manner.
Referring now to FIG. 4, the connecting member20 has a first end 22 fixedly secured to the mounting plate 12. In the illustrated embodiment, the first end is welded to the mounting plate. Walls 24, 26 of the connecting member each has an aperture 28 which extends through opposing sides of the connecting member 20 and is preferably located midway between the upper and lower surface of the connecting member. The connecting member 20 is preferably made out of 2¼ inch by 2¼ inch tubular steel. However, it should be appreciated that any size tubular steel can be used, such as 2 inch and 1⅞ inch or other appropriate sizes. Other metals can also be used without departing from the scope of the invention. An important object of the connecting member 20 is that it be able to selectively receive the extension member 14.
The extension member 14 includes first and second portions 34 and 36, respectively, and a base portion 40. The cross-section of the extension member is of a generally square shaped configuration. The first portion 34 extends outwardly from an end of the base portion at an obtuse angle such that the first portion is parallel to the connecting member 20. The second portion 36 extends outwardly from an opposing end of the base portion 40 also at an obtuse angle such that the first portion is generally parallel to the second portion. As shown in FIG. 4, the second portion 36 is positioned above the first portion 34. The extension member 14 is preferably made out of 2 inch by 2 inch tubular steel, but it can be fabricated in other sizes and shapes without departing from the scope of the invention. The extension member is fabricated from material of sufficient strength to withstand the load of a passenger on the seat positioned on portion 36.
The first portion 34 of the extension member 14 includes an aperture 42 which extends through both sides of the first portion and is preferably located midway between the upper and lower surface of the first portion. The apertures 28 and 42 substantially align to serve to secure the extension member 14 to the connecting member 20. In particular, the aperture 42 is spaced inward from an end of the first portion 34 such that as the extension member is inserted within the connecting member 20, the center axis of the aperture 42 is coincident With the center axis of the aperture 28. Preferably, the apertures 28 and 42 have similar diameters so that the extension member 14 can be secured within the connecting member 20 by a locking member such as a dowel or pin P extending through the apertures 28 and 42 when they are aligned with each other. The portion 34 is inserted into a mating opening 25 of a generally square shaped configuration in an end wall of the connecting member 20. The opening 25 is slightly larger than an outer dimension of the portion 34 to telescopically receive the portion 34.
According to one aspect of the present invention, the extension member 20 includes at least one seating frame 50, which extends generally perpendicular from the second portion 36 for supporting the at least one seat S. As shown in FIG. 4, the extension member includes a pair of seating frames 50. Each seating frame includes first and second arms 52 and 54, respectively, and a back portion 56, the arms and the back portion creating a generally “U” shaped frame. The first and second arms are fixedly secured to the second portion 36, preferably by welding. The first and second arms 52 and 54 include mounting apertures 60 adapted to receive conventional fasteners F for securing an underside of a conventional seat S to each seating frame 50.
The back portion 56 and the first and second arms 52 and 54 are preferably made of 1.5 inches by 1.5 inches tubular steel. The first and second arms 52 and 54 are secured to opposing end portions of the back portion 56 by welding or other suitable means.
According to another aspect (not shown) of the present invention, the mounting plate and the extension member are identical to the first embodiment in all respects, except that no seating frames are provided. In this embodiment, the second portion of the extension member includes at least one mounting aperture adapted to receive conventional fasteners for securing a single seat.
Referring to FIG. 5, an alternate embodiment of the passenger seat extension includes a foot support or protective shroud 61 which would be mounted onto extension portion 40 via fasteners (not shown) or onto the seating frame 50 via a leg portion 62. The foot support or shroud 61 can include a rectangular frame 64 and a grid or mesh 66 formed within the frame walls. The frame can be made of tubular steel or other metal. Another alternative would be to add a foot support onto the extension member adjacent portion 34 to provide a means for bracing and preventing the passenger from sliding down out of the seat. The foot support/protective shroud serves to support the feet of the passenger. Another use of the support is as a protective shroud to deflect debris, rocks, twigs, etc. from flying up toward the rear of the tractor. The support or shroud can be level as shown or at an angle to further deflect the debris.
Thus, the seating assembly is easily mounted to and disassembled from a rear frame of a tractor. The extension member can be easily interchanged with varying sizes and configurations of extension members without requiring removal of the mounting plate.
The present disclosure has been described with reference to the preferred embodiments. Obviously, modifications and alterations will occur to others upon reading and understanding the preceding detailed description. It is intended that the disclosure be construed as including all such modifications and alterations.
