CANOPY MOUNT BACKGROUND OF THE INVENTION 1. Field of the Invention The invention disclosed herein relates generally to tractors, and is more particularly concerned with protective or guardtype canopies for such tractors. In greater specifics and detail, the present invention pertains to an improved means for mounting such type canopies on tractors or the like. Canopies of this type are customarily mounted and installed on tractors, particularly of the track laying type, when the same are employed under such conditions and at such locations that the canopies become a necessity for protecting the operator of the tractor from falling objects, such as trees, timbers and the like, and for providing protection to the operator thereof against injuries resulting from the possible overturning or upsetting of such tractors.

2. Description of the Prior Art Tractors, particularly of the track type, have been widely employed in the forest and various other industries where considerable damage to the operator exists, for example from falling objects such as trees, timbers and the like, and also in places where such tractors have frequently been known to overturn. Therefore, there has been and is a continuing need for a protective or guard-type canopy for such tractors to protect the operator thereof.

Tractor canopies, of the type with which we are here concerned, customarily include strong rigid frame structures, and it has been customary to secure the canopy frame to the tractor by rigid securing means. However, due to the fact that some flexing or twisting of the tractor frame occurs as the tractor passing over rough ground and encounters obstacles and in spite of the fact that the tractor frame is substantially rigid, such relative movements between different portions of the tractor frame are transmitted to portions of the canopy through the customarily used rigid and unyielding connections between the canopy and the tractor frame. This is one explanation why failures and breaks in certain parts of the canopy and mounting means therefor are a common occurrence after a period of use with the tractor. Also a major difficulty encountered in providing canopies for tractors resides in the inability to compensate for the vibrations set up during the normal operation of the tractor, these vibrations producing undesirable rattles and noises as well as structural failures of the canopy and the mounting means therefor. These failures and breaks in the canopy and mounting means therefor can necessitate immediate repairing or replacement and involve loss of working time as well as repair expense. The present invention has been developed in order to enable the occurrence of such breaks and failures in the canopies and mountings therefor to be avoided.

While protective or guard-type canopies for tractors and the like and mountings or mounting assemblies therefor have been previously devised, such prior art devices and apparatuses being generally disclosed in U.S. Pat. Nos. 2,805,887; 3,036,858; 3,203,728 and 3,353,852, each has had certain drawbacks and disadvantages. Applicant's invention of an improved mounting assembly for a protective or guard-type canopy for a tractor is an improvement over such prior art devices and apparatuses as shown for example in the abovementioned patents.

SUMMARY OF THE INVENTION It has been found that the substitution of special mounting means for securing the protective canopy to the tractor with which a limited amount of flexibility and relative movement between the connected elements is provided will enable the occurrence of breaks or failures in the rigid frame of the canopy and the mounting means therefor to be avoided to a great extent in spite of the most vigorous employment of the tractor and without in any way rendering the protective canopy less effective in protecting the operator and tractor.

It is a general object of this invention to provide an improved mounting assembly for securing a protective or guard type canopy in place on a tractor frame which will permit necessary but a limited amount of flexibility and relative movement between the canopy and the tractor frames.

Another object of the invention is to provide an improved simply constructed mounting means for securing a protective canopy in place on a tractor frame which is readily installed with ordinary and existing tractor protective canopies, in which the noise and rattle is dampened and with which the vibration and structural failure is substantially reduced if not eliminated.

A further and more specific object of the subject invention is to provide an improved mounting means for a tractor canopy which will accommodate and absorb small relative movements in any and all directions between the connected parts of the canopy and tractor frame while still holding the canopy firmly in position on the tractor.

Still a further specific object of the instant invention is to provide an improved canopy mount wherein a major safety factor is provided in that even were the securing means portion thereof to break, the canopy would still not under normal circumstances be disengaged from the tractor.

Yet another object of the invention is to provide an improved mounting assembly which has an extremely long life due to the absence of direct metal-to-metal contact between the relative movable parts thereof, and wherein the normal maintenance thereof is reduced to merely an occasional replacement of certain parts of the mounting assembly which can be quickly slid into place without the necessity of cutting, welding and the like.

In general these objects are obtained by providing a mount ing assembly including a canopy post having a hollow lower end portion for attachment to a tractor frame and a generally upright pedestal having an upper free end adapted to receive the lower end portion of the canopy post therearound and a lower end secured to the frame. The pedestal includes a generally horizontal passageway extending therethrough with a pair of cushioning members being vertically spaced in the passageway to define an elongated opening therebetween. A bolt extends through the lower end portion of the canopy post and connects same to the pedestal, the bolt passing through the opening between the cushioning members and being in contact and supported by the lower of the cushioning members to maintain the lower end of the canopy post spacedly above the tractor frame.

BRIEF DESCRIPTION OF THE DRAWING The novel features which are believed to be characteristic of this invention are set forth with particularity in the appended claims. The invention itself, however, both as to its organization and method of operation, together with further objects and advantages thereof, may best be understood by reference to the following description taken in connection with the accompanying drawing, in which:

FIG. 1 is an elevational view of the improved canopy mount of this invention including adjacent portions of the canopy post and the tractor;

FIG. 2 is an enlarged transverse sectional view taken along line 22 of FIG. 1;

FIG. 3 is a transverse sectional view taken along line 3-3 of FIG. 2; and

FIG. 4 is an enlarged cross-sectional view taken along line 4-4 of FIG. 1.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawing in detail, and in particular to FIG. 1 thereof, the improved canopy mount 10 of this invention is used to mount or connect one of the posts, as at 12, of a protective or guard-type safety canopy to a tractor, tractor frame or other portions of a tractor, as at 14, with and on which the canopy is used. Canopy post mount 10 includes a base portion 16, a cushioning portion 18 and a securing means portion 20, all of which together cooperate and combine to provide an improved and cushioned mount for the posts of a typical protective or guard-type canopy for a tractor.

Base portion 16 includes a generally upright pedestal or member 22 having a generally horizontal upper surface or top 24 with a generally rounded or curved edge 26 extending therearound between the top surface 24 and the generally vertical portions thereof. Pedestal or generally upright member 22 fonns into and is terminated by a generally horizontally extending member or base 28 adjacent its lower end. Base or generally horizontally extending member 28 includes a flat generally horizontal bottom surface 30 for resting on and contacting portions of tractor 14, and a bevelled or downwardly and inwardly inclined outer edge or surface 32 extending therearound forming a pocket or cavity between tractor 14 and outer edge or surface 32 for the securing of the base portion 16 to tractor 14 by appropriate welding or welds as at 34 therearound. If so desired, base portion 16 could be attached to tractor 14 by other appropriate securing means, such as bolts extending through holes therein (not shown). Generally horizontally extending member 28 of base portion 16 further includes a generally horizontal shoulder 36 extending therearound and spaced outwardly from generally upright or pedestal member 22 of the base, the purpose and function of which will be explained more fully hereinafter. A smoothly curved edge or inner surface 38 extends around the lower end portion of pedestal 22 and connects the generally vertical surfaces thereof with the generally horizontally extending shoulder 36 of generally horizontally extending member 28.

The pedestal or generally upright member 22 of base portion 16 includes a rectangular shaped passageway 40 extending therethrough adjacent its lower end portion. Passageway 40 is provided with a pair 41 and 42 of yieldable hard rubber or rubberlike cushioning members which substantially fill passageway 40 between its sidewalls and its top and bottom walls, with the exception of a central elongated opening or passageway 44 extending between the spaced cushioning members 41 and 42. Passageway r elongated opening 44 is provided for the reception of securing means portion 20 therein and therethrough between cushioning members 41 and 42. Substantially identical cushioning members 41 and 42, which are firm but yieldable, cushion securing means portion 20 within passageway 44 therebetween and permit limited vertical movement of the securing means portion 20 within opening 44 and passageway 40. It has been found advantageous to employ a laminated reinforced rubber material in lower cushioning member 42, such as that marketed under the trademark FABREEKA by the Fabreeka Products Company, incorporated.

The height of opening 44 between members 41 and 42 is of a size sufficiently large to readily accommodate securing means portion 20 therein, but not overly large to cause unnecessary play. The width of opening 44 is of sufi'rcient size such that a small amount of space exists between each side of securing means portion 20 and the adjacent respective sidewall of passageway 40, thereby preventing metal to metal contact between securing means portion 20 and pedestal 22 of base portion 16.

The cushioning portion 18 of assembly includes a hard rubber rectangular sleeve 46 having sides 48, 50, 52 and 54 which are joined at their corners and which fits snugly around the pedestal or generally upright member 22 of base portion 16. Sleeve 46 is positioned about pedestal 22 adjacently above shoulder 36 and extends upward therefrom to a point adjacently downward of the top surface 24 of pedestal 22. Side portions 50 and 54 of sleeve 46 have respective passageways 56 and 58 extending therethrough to permit securing means portion to pass through sleeve 46 and into opening 44 between members 41 and 42, and then outwards therefrom through sleeve 46. Sleeve 46 is fabricated of a hard rubberlike material such as neoprene, to cushion the sideways or horizontal movement and prevent contact between the inner surface of canopy post 12 and generally upright pedestal 22, thereby reducing the noise, vibration, wear and fatigue between these two surfaces of the canopy post and mounting means therefor.

Securing means portion 20 includes a bolt 60 having an elongated shank or body portion 62, an enlarged bolthead 64 at and secured to one end thereof, while the other end of shank 62 is provided with a threaded portion 66. Securing means portion 20 is completed by a locking-type nut 68 threaded and secured on threaded portion 66 of elongated shank 62 of bolt 60.

Comer post 12 of the tractor canopy is provided with respective aligned circular openings 70 and 72 on its opposite side portions adjacent its lower end portion 74 through which the elongated shank portion 62 of bolt 60 extends in securing comer post 12 to canopy mount 10, and more in particular to generally upright pedestal 22 of base portion 16 thereof. Elongated shank portion 62 of threaded bolt 60 also extends through openings 56 and 58 of respective sides 54 and 50 of sleeve 46 and through opening 44 between members 41 and 42 in securing all portions of canopy mount 10 and canopy post 12 together.

When the canopy post 12 is secured to canopy mount 10, the shank portion 62 of bolt 60 extending through opening 44 between cushioning members 41 and 42 is permitted limited general vertical movement within passageway 40 between members 41 and 42, thus permitting small amounts of relative movement between the pedestal 22 of base portion 16 and corner post 12 to be absorbed by cushioning members 41 and 42. In this manner, there is no metal-to-metal contact between comer post 12 and pedestal 22 of base portion 16 or between the bolt 60 and pedestal 22 of base portion 16, thus eliminating much of the noise, vibration, wear and failure experienced in prior art canopy post mounting arrangements.

In using the improved canopy mount 10 of this invention, the base portion 16 thereof is first secured to tractor 14 at appropriate places thereon by welds, such as at 34. Next cushioning members 41 and 42 are placed within opening 40, or the same may have already been accomplished before the securing of base portion 16 to the tractor, and then sleeve 46 is fitted in place over generally upright pedestal 22 with the openings 56 and 58 thereof in alignment with elongated opening 44 between members 41 and 42. Now canopy post 12 is positioned over pedestal 22 of base portion 16 and sleeve 46 positioned thereon. Finally canopy post 12 is secured to mount 10 by means of the securing means portion 20, which is accomplished by positioning bolt 60 through the appropriate openings in post 12, sleeve 46 between members 41 and 42 and securing locknut 68 on threaded end portion 66 thereof. If in use, cushioning members 41 and 42 or sleeve 46 of canopy mount 10 should become excessively worn they may be readily replaced by disconnecting canopy post 12 from mount 10 by operation of securing means portion 20. Furthermore should bolt 60 of securing means portion 20 fail or shear for some unknown reason, canopy post 12 will fall by gravity to the point where lower end portion 74 comes to rest on shoulder 36 of base portion 16 whereby canopy post 12 remains attached and secured to mount 10 until a later time and when appropriate repairs can be conveniently made.

While only a certain preferred embodiment of this invention has been shown and described by way of illustration, many modifications will occur to those skilled in the art and it is intended that all such modifications be included within the true spirit and scope of this invention.
