The present invention relates generally to motorcycle accessories and more particularly to a novel mounting system for windshields and other accessories. The invention particularly relates to a novel mounting system which provides maximum simplicity, but also enables one to mount and dismount motorcycle windshields and other accessories from the cycle with ease and precision.
Although there are many different mounting systems for motorcycle windshields and the like, it would be particularly advantageous to provide such a system wherein the shield may be reliably attached to and removed from the motorcycle in a matter of seconds. This would be particularly true wherein the mounting system could comprise four docking points permanently affixed to the cycle, but would not leave unsightly or bulky fastening means on the cycle when it is desired to use the cycle without the shield or other accessory.
When the time comes to mount or affix the shield or other accessory, this can be done in a few seconds by a person having almost no mechanical skill. For example, it would be highly desirable to provide an accessory for mounting windshields or other accessories, wherein the docking points could be affixed to the motorcycle and remain there permanently, while the shield itself and the two brackets for mounting it could be removed and stored as a unit without further disassembly. Particularly, it would be desirable if there were such a system wherein the docking points used to mount the shield could be affixed to the motorcycle and thereafter be allowed to remain there without distracting from the appearance or function thereof, and without presenting any ungainly elements or the like such as protruding screws, studs, brackets or braces. It would also be advantageous if a simple mounting system could be placed relatively permanently on the cycle which would enable the shield to be mounted by placing the lower portion on a pivot point and thereafter merely snapping it into place by a backward (in relation to the cycle) motion into a secured position.
It would also be desirable to make a shield which would be able to be removed by a forwardly acting force, such as from the force of a rider being thrown forward in the event of an accident, whereby the shield would be detached rather than remaining in place and injuring the rider.
It would also be advantageous to provide docking points that could be fastened to or form a part of the front forks, the triple clamps, or the front fork covers themselves.
Accordingly, it is an object of the present invention to provide an improved mounting system for a windshield or the like.
Another object is to provide a unique mounting system wherein the mounting bracket on the shield includes one upper or lower surface that is relatively smooth but curvilinear and the other with an opening or notch in an oppositely directed latching claw which is automatically raised or lowered to facilitate ready installation and latching without touching or manipulating the claw.
Another object is to provide a novel flanged mounting member with a center trough, and preferably having a urethane elastomer or other somewhat flexible center section, including inclined spokes or a garter spring and further optionally having a thin, hollow innermost sleeve, making a unique composite mounting member capable of allowing a limited amount of radial deflection as it is being installed and thereafter absorbing shock and/or slight errors in alignment or dimensional variation.
A further object is to provide a mounting system for other accessories which would use the same or similar arrangement of latching members for mounting and removing saddlebags or other accessories.
A still further object of the invention is to provide a simplified system of mounting and dismounting the windshield or other desired accessory.
Another object is to provide a mounting system that does not require extreme precision in locating the docking points on the cycle.
A still further object is to provide a mounting system having a latch or claw on each bracket without affecting the simplicity of operation.
A still further object is to provide a mounting system that is virtually foolproof in operation.
Yet another object is to provide a system which permits ease of installation and removal as well.
These and other objects of the invention are achieved in practice by providing a pair of flanged members, preferably such as wheels, spools or rollers, one of which may remain fixed, and optionally may be rotatable, and other which is preferably not only rotatable but is also preferably able to undergo slight radial deformation or deflection under an applied load, and thereafter to cooperate with a bracket having one fixed edge and a movable latching claw with strong biasing means urging the claw to a closed position, and which may then be installed or removed readily without manipulating the latching claw in any way.
The manner in which these and other objects and advantages are achieved in practice will become more apparent when considered in connection with the following description of the preferred embodiments of the invention and shown in the accompanying drawings, wherein like reference numbers indicate corresponding parts throughout.
While the invention may be practicing several different ways, and there will be room for modifications or changes to be made by those skilled in the art, a brief description will be made of at least two preferred embodiments of the invention.
Referring now to the drawings in greater detail, there is shown in
It will be understood that the entire windshield 10 is actually affixed by a pair of brackets (only one shown) to a pair of fork tubes (only one shown). In this instance, the bracket 12 is shown to be affixed to the right hand portion of the cycle. Referring now to the bracket generally designated 12, it is shown to include a mounting flange 20 having a plurality of openings 22, 24, 26 therein for affixing it to the windshield. The remainder of the bracket 12 comprises an upper portion 28 which is angularly related to the flange 20 and which also includes a lower portion 30 having a lowermost opening in the form of a slot 32 therein. A larger, upper slot generally designated 34 is shown, it being understood that this slot has a portion which is generally semi-circular in form.
An important feature of the upper slot 34 and its associated latching claw assembly generally designated 38 is their ability to at least partially close off the opening 34. The latching claw assembly generally designated 38 preferably includes a contoured claw member 40 (
The claw assembly 38 also includes a retainer or holder 54 for the upper portion of the coil spring 46, and a partially cylindrical formation 56 for housing the body of the spring 46. The claw assembly 38 also includes a principal body portion 58, an offsetting surface 60 and the contoured claw itself 40 which will be discussed later. In use, the spring 46 rests on the spring perch 48 and is entrapped in the housing 56 by means of the retainer 54. In this arrangement, the claw 38 may be moved upwardly against the spring force as the spring is compressed on its perch 48.
The upper opening 34 in the bracket 12 is shown to include a number of additional features including an inclined entry surface portion 64, a curvilinear retention surface 36, and a further upwardly extending exterior surface 66 that extends to the top of the bracket 12.
The wheel or spool generally designated 73 is shown in
The action of the latching claw 38 in snugly engaging the trough 72 of the wheel 73 to secure the bracket in place is accomplished through the action of the coil spring 46 acting on the latching claw 38. The rest position of the latching claw 38 is the position shown in
Thus, the lower slot is first engaged over a bottom bracket holder such as the wheel or spool 95. Thereafter, the windshield, and accordingly the brackets 12, are moved backwardly and against the wheel 73 which is held in position by means of the fasteners 16. The elastomeric portion 74 of the wheel 73 helps the wheel 73 to ride over the inclined entry surface 64 of the bracket 12 and snap into place in the retention surface 36, with the latching claw 38 grasping the wheel 73 as the wheel 73 rides over the transition surface 40 and into the curvilinear retention surface 43.
Referring now to the attachment of the spools or wheels 73, 95, the fasteners 16 each include a headed portion 84, a threaded shank portion 86 and intermediate cylindrical portion 88. The threaded portion 86 extends into the forks or fork covers 14 as shown, and this positions the wheel 74 adjacent the fork tube or fork tube cover.
In the same manner, each fastener 18 includes a headed portion 90, a threaded shank portion 92 and an intermediate portion 94 which is free from threads or the like. This fastener is intended to secure the lower wheel generally designated 95 to the fork tube generally designated 14. The intermediate portions 88, 94 serve to allow the wheels 73, 95 to turn freely even when the fasteners 16, 18 are tightened down securely.
Referring now to the operation of the device, it is assumed that the windshield assembly 10 is intended to be latched in position of use on the motorcycle. The user stands in front of the motorcycle and grasps the shield 10 at either side adjacent the brackets 12. The user then places the lower slots 32 over the wheels 95. The next step is to rotate the shield 10 slightly as it is moved toward the rear of the motorcycle. While doing this, the upper wheel 73 slides over the inclined entry surface 64 and into the curvilinear retention surface 36, while the upper wheel 72 rides into this position by displacing the claw 38 first upward over the transition surface 41 and then allowing the claw 40 to achieve a lower position with the retention surface 43 snugly overlying the wheel 73.
The trough 72 of the wheel 73 first serves to raise the latching claw over the trough until the wheel is registered with and is seated between the claw and the curvilinear retention surface 36. This is met with a comparatively strong resistance, thus advising the user that the shield has snapped in place. When the claw 40 rides up and then over the trough 72, the claw 40 compresses the spring 46 as the claw 40 rotates about the pivot point formed by the rivet 42. When released, the coil spring 46 pushes downwardly on the latching claw 40, in response to spring pressure. The claw then retains its snugly held position against the trough of the wheel 73 and with both retention surfaces 43, 36 registering with the wheel 73.
The shield is then retained in place, preferably with about 30 to 40 pound retaining force developed by the claw and the contours of the bracket and claw. Of course, in use, the shield will not become detached because it is solidly pressed in place, and during riding, there is little or no forward force acting on the shield. The elastomeric center section 74 of the wheel 73 takes up some or all of the dimensional variations in the assembly. To release the shield, the opposite procedure is followed. Only 30 to 40 pounds of force in the reverse direction are needed. To remove the shield, the latching claw moves itself temporarily upwardly against the force of the spring 46, because of the contour of the claw and the various surfaces. When the claw is released, and the shield is pivoted forward, it then may be lifted slightly to free the wheel 95 from the slot 32, and the shield may be stored or otherwise dealt with.
Referring now to
In this embodiment, the spring 146, the spring perch 148, and the housing 156 are the same except that the spring is to be compressed in an upward direction rather than a downward direction. The rivet 142, is the same as in the other embodiment. The lower slot or other opening 132 is the same as its counterpart in
The inclined entry surface 135 and curvilinear retention surface 136 engage one trough surface 172 of the spool. In this instance, a somewhat enlarged opening, including a relatively straight line formation 143 makes up the overall opening in the bracket 112. This portion of the latching mechanism is a straight line 143 and affords a larger entrance for the offset portion 145 of the claw 138, which must have clearance for its limited movement.
In the first embodiment, there is a somewhat slanted surface which limits the upward travel of the claw.
An important feature of the present form of device described herein is that it may be attached and detached from the motorcycle with very little effort, and yet when in position, is retained very securely. Also very importantly, the wind screen or other accessory may be mounted without the need for the user to hold or manipulate any levers or claws. The user need only place the shield in position and push it rearwardly in the case of installation, or pull it forward in the case of removal. The inclined surface portions and the transition surface portions cooperate to provide an easy entry into the curvilinear retainer portions, where the combination of the curvilinear retention surface and the biasing force on the claw retains the entire windshield in a snugly seated position.
The inclined surface and a transition surface both combined to allow the spools to be held snugly with the round shape of the spool trough being about the same as the curvilinear retention surface portions on the bracket and the claw. The optional rubber lying radically inside the trough portion permits tolerances to be taken up, and absorbs vibration during use. As pointed out, the wheels or spools may contain another form of flexible center sections. These include inclined spokes or a garter spring, preferably an inclined garter spring.
The vertical movement of the windshield during installation is very slight but the slot formation on the bottom of the bracket will easily helps account for such tolerances to be taken up.
Whereas two embodiments have been described wherein the shield or other accessory is placed on the cycle with a generally horizontal motion, it is possible, with suitable modifications, to provide an accessory with brackets and claws that act generally vertically instead of horizontally. Thus, with the appropriate form of openings and latching claws, the windshield or other accessory could be placed on, and removed from, the motorcycle with a generally vertical motion.
It will thus be seen that the present invention provides a novel windshield or other accessory mounting system having a number of advantages and characteristics including those pointed out herein and others which are inherent in the invention. It is anticipated that various changes may be made and that variations will occur to those skilled in the art, and that these changes and variations may be made without departing from this spirit of the invention of the scope of the appended claims.
