A handgrip that may be installed on the handlebar of a jet-ski, a motorcycle, or bicycle. The grip has three major components which are the major tubular handgrip member, a tubular sleeve, and an end cap. The major tubular handgrip member has the tubular sleeve member slid on over its outer surface and until it abutts an annular ridge. The end cap is then inserted over the tubular neck portion until it abutts the tubular sleeve. An adhesive on the tubular neck portion holds the end cap in position. The tubular sleeve is made of open cell foam material which is gripped by the palm of the rider's hand. The tubular sleeve functions to prevent blisters to the rider's hand.

BACKGROUND OF THE INVENTION 
The invention relates to handlebars and more specifically to a unique 
handgrip that can be used on the handlebars of jet-skis, motorcycles, and 
bicycles. 
Presently most handgrips on the market are formed as a unitary solid 
member. Many of these are made of the thermoplastic rubber polymer 
material such as Kraton. Other models are made of real rubber and cheaper 
models are merely made of plastic material. 
One of the most annoying features of existing handgrips is that the rider 
of the vehicle develops blisters on the palms of their hands for gripping 
the handgrip. 
Another problem that exists is the fact that handgrips on many vehicles 
tend to slip or spin in the rider's hand. Although the handgrips are often 
installed with an adhesive coating on the handlebar, water, dust and dirt 
that get into the interior of the handgrip loosen them and cause them to 
turn. Sometimes the heat from the palm of the rider's hands get the grip 
warm enough so that it will cause the adhesive to release and allow the 
grip to spin. One method of overcoming this problem is to have a pair of 
laterally spaced annular grooves in the handgrip and the rider winds 
safety wire around these grooves and twists them with pliers to tighten 
them firmly against the handlebars. 
It is an object of the invention to provide a novel handlebar handgrip 
having unique structure which prevents the occurance of blisters on the 
palms of the hands of a rider. 
It is also an object of the invention to provide a novel handlebar handgrip 
made of three individual members that are assembled together. 
It is another object of the invention to provide a novel handlebar handgrip 
that is economical to manufacture and market. 
It is a further object of the invention to provide a novel handlebar 
handgrip that is easily installed on the handlebar of a jet-ski, a 
bicycle, or motorcycle. 
SUMMARY OF THE INVENTION 
The inventor's novel handlebar handgrip has been designed to prevent 
blisters from forming in the palms of the hands of a rider of jet-skis, 
bicycles, and motorcycles. It is formed of three individual components and 
they are the end cap, the tubular sleeve, and a major tubular handgrip 
member. 
The major tubular handgrip member is preferably made of a thermoplastic 
rubber polymer material such as Kraton. From its outer end in sequence it 
has a tubular neck portion, a tubular intermediate portion, a tubular base 
portion, and disc-shaped end portion. An annular groove is formed on the 
outer surface of the major tubular handgrip member between the disc-shaped 
end portion and the tubular base portion. This annular groove is designed 
to receive a length of safety wire that is wrapped around it and tighted 
by the rider of the vehicle. An annular ridge is formed on the outer 
surface of the major tubular handgrip member between the tubular base 
portion and the tubular intermediate portion and it functions to restrict 
the travel of the tubular sleeve when it inserted thereon. 
The tubular sleeve member is preferably made of an open cell foam material 
such as neoprene. It has an inner diameter substantially the same as the 
outer diameter of the tubular intermediate portion of the major tubular 
handgrip member so that they frictionally engage each other. The length of 
the tubular sleeve member is approximately in the length of 2" to 2 and 
1/2". It is its cushioning feature that prevents blisters from forming in 
the palm of the rider's hands. 
The end cap is also preferably made of a thermoplastic rubber material such 
as Kraton. The tubular neck portion of the major tubular handgrip member 
has an adhesive applied to its outer surface and the end cap is then slid 
over it after the tubular sleeve has been slid onto the tubular 
intermediate portion. An annular groove is formed on the outside surface 
of the end cap adjacent its forward end for receiving a safety wire that 
is wound around it and tightened.

DESCRIPTION OF THE PREFERRED EMBODIMENT 
The novel handlebar handgrip will now be described by referring to FIGS. 
1-5 of the drawing. The handlebar handgrip is generally designated numeral 
10. It is formed of three major components, end cap 12, tubular sleeve 14, 
and major tubular handgrip member 16. 
End cap 12 has an annular flange 18 formed on its one end and an annular 
groove 20 formed adjacent its other end. The inner end of the end cap has 
a bore having a diameter D1 that extends into tubular portion 22 until it 
abutts a shoulder 24. Tubular portion 22 has a plurality of longitudinally 
extending reinforcing ribs 21 around its outer surface. 
Major tubular handgrip member 16 has a tubular neck portion 30 whose outer 
diameter D2 is substantially the same as diameter D1 of the end cap 12. A 
shoulder 31 forms the start of the structure of the tubular intermediate 
portion 32 and it has an annular ridge 33 formed at its opposite end. The 
outer diameter of tubular intermediate portion 32 is D3 and that is 
substantially the same as the inner diameter D4 of tubular sleeve 14. 
Tubular base portion 35 abutts annular ridge 33 and it has an annular 
groove 37 formed at its other end. A disc-shaped end portion 39 forms the 
inner end of the major tubular handgrip member 16 whose overall length is 
L1. The length of tubular intermediate portion 32 is L2 and it 
approximates the length L3 of tubular sleeve 14. Major tubular handgrip 
member 16 has an inner diameter D5 that extends throughout its length. 
The safety wires 50 are illustrated installed on the handlebar handgrip in 
FIG. 1.
