9 Claims.

This invention relates to a motorcycle windshield and it is particularly concerned with means for mounting the windshield on the handle bars of the machine.

Windshields for motorcycles have, of course, been long well known. The constructions heretofore known have been such as to require diilerent mounting arrangements for the two classes of handle bars which may be typified as braced and unbraced handle bars.

The object of the present invention is to provide a universal mounting arrangement which will permit the windshield to be mounted interchangeably on both forms of handle bars. It is also an object of the present invention to provide a universal mounting arrangement which will be simple in construction and easy to adapt to the respective types of handle bar constructions and, in general, it is the object of the invention to provide an improved windshield structure of the character indicated.

Other objects and advantages of the invention will be understood by reference to the following specification and accompanying drawing, wherein there is illustrated a selected embodiment of the windshield and its manner of attachment to the indicated two classes of handle bar constructions.

In the drawing:

Fig. 1 is a perspective illustrating the windshield attached to a braced type of handle bar structure;

Fig. 2 is a fragmentary illustration of the mannor in which the windshield is attached to an unbraced type of handle bar construction;

Fig. 3 is a detail illustrating a form of clamp construction employed.

In the drawing, a braced handle bar construction, as shown in Fig. 1, comprises a main tubular member I which is bent to more or less U-shape and provided at about the middle or its connecting member 2 with means for securing the handle bar structure to the front wheel fork of the motorcycle. Such attaching means is typified in Fig. 1 by the centrally located apertured lug 3. The side arms 4-4 of the handle bar have their free ends provided with grips 5, usually of rubber or other suitable material.

In the braced form of construction shown in Fig. 1, the side arms 4-4 are additionally connected by a transversely extending tube It which has its opposite ends welded to the respective arms 4.

Some makes of motorcycles are equipped with a braced handle bar structure as shown in Fig. 1,

while others eliminate the transverse member 6 by making the U -shaped member of tubing which is considered strong enough for handle bar purpose without transverse bracing.

The windshield structure comprises a screen which in this instance embodies a transverse sheet 1 of flexible plastic material which is secured to a suitably arched metal bar or bracing member 8. In this instance attachment is effected by bolts 9-9 which extend through the ends of the arched member 8 and the transparent member I. Also, an upwardly extending arched rod i0 is welded or otherwise rigidly secured at its lower ends to the end portions of the bar 8 for supporting the upper portion of the windshield member I.

In the construction shown the transparent member 1 extends both above and below the arched supporting member 8 but in many constructions the transverse member terminates adjacent the lower edge of the arched member 8 and the lower portion of the member 1 is replaced by suitable fabric or other material. The lower edge ll of the windshield member I is suitably are suitably drilled to provide sockets to rotatably receive the upper end portions l3 of mounting rods l4. Said upper portions l3 are suitably threaded to receive cap nuts IS on their upper ends and lock nuts l6 which may be adjusted toward the cap nuts l5 to clamp the rods 14 in fixed position in the bosses or lugs l2.

The lower ends of the rods l4 pass through openings in cylindrical members indicated at ll which are slidable in sleeves such as indicated at "3. The members H and I8 are secured by a conventional bolt l9 to the upwardly projecting ears 20-20 of a clamp structure 2! which 18 adapted to be secured to any tubular frame element such as the brace member 6 or the handle bar element 4. The clamp 2| comprises opposite halves 22 and 23 which have depending ears or lugs 24-24 which are drawn together by suitable bolt and nut 25. Bolt I9 threadedly engages a suitably tapped opening in the member I! so as to be adapted to pull the member I! into the sleeve 3, thereby to pull the rod I4 into engagement with the outer end of the sleeve l8 and the other end of the sleeve l8 into engagement with the adjacent ear 20 of the clamp. By properly tightsuing the bolt is, the mounting rod 14 is locked in position and the clamp 2| is also tightened on the frame member on which it is placed.

The mounting rods M are provided intermedl ate their ends and preferably near their upper portions IS with angularly disposed offset portions 26. When the windshield structure is to be mounted on a braced handle bar construction as shown in Fig. l, the mounting rods M are rotatably adjusted in the bosses l2 so as to position the lower portions of the rods to enter the appropriate holes in the clamps when secured to the brace member 6 as shown.

When the windshield structure is to be mount.- ed on a so-called unbraced handle bar construction, the clamps M are positioned on the side arms 6 as shown in Fig. 2 and the mounting rods 14 are rotatably adjusted in the bosses I! so as to assume an outwardly offset position relative to the position shown in Fig. l and in which cut-- wardly ofiset position the lower ends of the rods will register with the appropriate openings in the clamps 2i. When the mounting rods I4 are properly adjusted, the clamping or lock nuts It should be tightened to lock. the rods It in their adjusted positions.

As indicated in Figs. 1 and 2, the lower portions of the rods, i. e., the portionswhich depend from the angular intermediate portions 26 diverge outwardly and downwardly from an extension of the axis of the upper portions E3 of said rods; that is to say, that the opposite end portions of the mounting. rods. are preferably not parallel but are disposed at an angle to each other. This arrangement provides the required amount of movement of the. lower ends of the rods for interchangeable mounting described. It will, of course, be apparent thatthe clamp 2| may be so positioned on the-handle bar element and that the member IT may. be rotated on its own axis to cause the hole in the member I! to be properly aligned with the angularly disposed lower portion of the member I4.

The described arrangement is sufficiently adjustable to adapt the windshield to mounting on practically all present mak-esof motorcycles and it simplifies or overcomes the problems encountered by manufactures and dealers in manufacturing and. handling windshield structures made specially to fit each prevailing type orhandle bar construction.

Changes in the structure may be made withoutdeparting from the scope of the invention as setforth in the following claims.
