Primary Examiner-James T. McCall Attorney-John Walker [5 7] ABSTRACT A motor cycle back rest which can be mounted by means of an articulate framework. The back rest proper can be adjusted up or. down. Further adjustment of the backrest, consistingof angle of tilt, and movement toward and away from the front of the motor cycle, is provided by the design of the framework by which it is supported.
6 Claims, Drawing Figures MOTOR CYCLE BACK RESTS This invention relates to back rests for motor cycles, and more particularly to the type of back rest adapted to the necessary adjustments .whereby it can be installed on any one of a wide range of motor cycles of different makes and models.
, It is well known that back rests of various designs have been proposed in the past, however, unless such a device is designed to provide freedom of adjustment in any direction within a longitudinal plane of the cycle to which it may it may be attached, it does not serve it purpose in an entirely satisfactory manner. In addition to the fact that different makes of machines require different adjustments of auxiliary equipment installed thereon, the requirements of individuals using. identical machines may also vary to a considerable extent.
It is the principal object of the present invention to provide a back rest which can be adjusted up or down, backward of forward, and which can be also also sloped or tilted as required.
Another object of the invention is to provide all of the foregoing adjustments without conflicting limitations in the making of each.
A further object of the invention is the provision of a back rest which can be removed from .a motor cycle while still retaining all of the adjustments except the actual point of fastening, or which can be collapsed as occasion demands. A
' These and other objects of the invention will become apparent during the course of the following description, taken in connection with the accompanying drawing forming a part hereof and in which: v
FIG. 1 is a side elevation of the back rest.
FIG. 2 is a rear elevation.
FIG. 3 is a fragmentary top plan'as seen from line 3 3 of FIG. 1.
FIG. 4 is a fragmentary bottom plan as seen from line 44ofFIG.l. j
Referring to the drawing in detail, the back rest proper comprises a base plate with upper and lower and are integral with a transverse, horizontal connecting portion 18 of said support, as is illustrated in FIG. 2. It has been established that, in the majority of applications, the angular relationship betweenthe rearwardly extending portion of the support 16 and the upwardly extending portion thereof is substantially uniform, however, adjustment of this relationship has been provided by means of conventional, radially serrated joints 19, locatedclosely adjacent the lower bends of the support 16 in case such ad adjustment is required.
A pair of upper side struts 20 are pivotally attached, at their remote ends, to lugs 21 on the bracket 11, at one end, and to a point intermediatethe joints l9 and the upper end 18 of the main frame support 16. Connection between the back rest assembly and the main frame support is thereby made. Also pivotally attached to the upper bracket 11, by means of additional lugs 22, is a center strut 23. This strut passes under, and is adapted to be in contiguous relationship with the traverse portion 18 of the main frame support 16. An inverted U shaped'clamp 24 straddles the transverse portion 18 of the main frame supportil6 and'is provided with apertures through which the center strut passes. Thumb screws 25, in the clamp 24, provides one of the points of adjustment of the aforementioned frame support brackets 11 and '12 respectively. Slidably mounted upon the baseplate is the actual rest 13 which will, of course, be provided with a cushion C as in dicated in phantom on FIG. I. The upper and lower ends of the back rest 13 are provided with a plurality of threaded apertures 14 spaced along the longitudinal median line thereof. Complimentary apertures are located in the brackets 11 and 12, one in each bracket, and they also pass through the base plate 10. These two apertures are so spaced as tocoincide, in their respective alignments, with the apertures 14 in the back rest 13. This arrangement, as can be clearly seen from FIG. 1, permits adjustment of the back rest 13 upon the base plate 10 in one or another of a number of different positions. Thumb screws 15 are provided to lock the back rest in the selected, adjusted position.
Actual attachment of the back rest to a motor cycle is made by a framework of pivotally connected and adjustable tubular members. One of such members, the main frame support 16, is of bifurcated construction. One leg of the support extends rearwardly, in a substantially horizontal direction, from each side of a motor cycle to which it may be secured. Clips 17, or other suitable means, are provided for this purpose) The furcations of the support then follow an upward direction framework. Inorder to obviate the possibility of slippage at this point, a spring pin or cotteris inserted into the appropiate one of a number of apertures 27in the center strut 23. Fastening of the clamp 24 establishes the longitudinal position of the upper end of the back rest with reference to the main support 16.
The angle of tilt of the back rest, and the prevention of further pivoting of the framework at the point of connection with the bracket '11 is maintainedby the provision of a pair of lower struts 18. These struts are pivotally connected to the bracket 12 by means of pins or bolts extending through the members, and through lugs 29, insimilar fashion to the connection of the framework at the upper end of the backrest. The lower struts are then swung. upwardly between the upper struts 20, each pair being so spaced that contact is maintained between each adjacent member when in any adju'stedposition. Such positions are maintained by one of a pair of bolts or pins 30 passing through a single aperture in each of the upper struts 20, and engaging one of a series of spaced holes 31 through the lower struts 28.
It will be apparent from the foregoing description that a wide range of adjustments is made possible by the design so disclosed. Manipulation of the pins 30,
'and the clamp 24, will enable the back rest to be set at any desired angle, and at the right location relative to the seat S of the motor cycle to which it may be attached. Further adjustment of the back rest on the base plate can then be made as desired.
The terms forward, rearwardly and longitudinally are used in the context having reference to an assembled unit mounted on a motor cycle.
Having illustrated and described a preferred embodiment of my invention, it should be understood that modifications may be made within the spirit and scope of the appended claims.
