VEHICLE HANDHOLD STRUCTURE
FIELD OF THE INVENTION
The invention relates generally to a handhold
~tructure, such as motorcycle handgrip and automobile
steering wheel and in particular to a handhold structure
having hand massage projections formed thereon to ma~sage
the hand holding it during the operation of the motorcycle
and automobile.
BACKGROUND OF THE INVENTION
Driving for a long while is a very tired job. For
professional long distance drivers, relaxation of both
physical and mental strain is extremely needed after a long
while driving to ensure safe driving thereafter.
It is therefore desirable to provide a handhold
structure for automobile steering wheel and motorcycle
handgrip which has a plurality of projections formed thereon
to contact and massage the muscle of the hand holding it to
release the strain of the muscle due to long term holding.
SUMMARY OF THE INVENTION
The principal objective of the present invention is to
provide a handhold structure for an automobile steering
wheel which comprises a plurality of round projections of
suitable size formed on a tubular base mounted on the
- ':
. -.
~3~
steering wheel so as to contact and thus massage the hands
h~lding the steeriny wheel.
It is a further objective of the present invention to
provide a handhold structure for a motorcycle or bicycle
handgrip which comprises a plurality of round projections of
suitable size formed on a tubular base to be fit over the
- handgrip so as to contact and mas~age the hand holding the
handgrip.
To achieve the above-mentioned objectives/ there is
provided a handhold structure for use in an automobile
steering wheel or a motorcycle handgrip comprising at least
a tubular member to be fit on the steering wheel or handgrip
with a plurality of projections of desired shapes having
rounded top end, such as arch shape, hemisphere shape, semi~
ellipsoidal shape or round-end conical shape, uniformly
distributed thereon to contact and massage the hand(s)
holding it.
BRIEF DESCRIPTION OF THE DRAWING

DETAILE~ ~E~ TION OF THE PREFERRED EMBoDr~ENTs
With reference to the drawings and in particular to
FIGS. 1 and 3, wherein a first embodiment of the handhold
structure 10 in accordance with the present invention which
is applicable to an automobile steering wheel 40 is shown,
the handhold structure 10 of the present invention comprises
an elongated tubular base 11 shaped to be securely fit on
the steering wheel 40. A plurality of projections 12 of
:
desired shapes and size with rounded top ends are uniformly
distributed on the outer surface of the tubular base 11 to
contact and massage a hand 90 (see FIG. 3) holding the
steering wheel 20.

The suitable shapes of the projections 12 may include
arch shape, hemisphere shape, semi-ellipsoid shape or round-
end cone shape. Certainly, other shapes having rounded top
end may also be adopted, as is quite obvious to those having
ordinary skills.
Preferably, the tubular base 11 and the projections 12
are formed by a material of suitable resiliency in a single
piece. Suitable material may include rubber and plastics.
Preferably, the tubular base 11 has an elongated slit
13 formed along the length thereof to allow the tubular base
11 to be fit on the steering wheel 40.
In FIG. 2, a second embodiment of the present invention
is illustrated which is an application of the handhold
,
structure designated by the reference numeral 20 in this
second embodiment to a steering wheel 50 of another type
which comprises two separated segments 51 and 52. In this
embodiment, the handhold structure 20 of the present
invention comprises two tubular bases 21 and 22 to be
respectively securely fit on the two segments 51 and 52 and
each of the two tubular bases 21 and 22 has a plurality of
round projections 23, which are the same in structure as the
projections 12 of the first embodiment shown in FIGS. 1 and
3, uniformly distributed thereon. Obviously, the cross~
sectional view shown in FIG. 3 is also applicable to the
second embodiment shown in FIG. 2.

The present invention may also be applied to the
handgrip of a motorcycle or a bicycle (not shown), such as
the third embodiment shown in FIGS. 4 and 5.
With particular reference to FIGS. 4 and 5, in which
the third embodiment of the handhold structure, designated
by reference numeral 60, of the present invention for a
motorcycle or bicycle handgrip 30 (FIG. 5) is Rhown, the
handhold structures 60 comprises a tubular base 31 having an
open end 32 to allow the tubular base 31 to be fit over the
motorcysle or bicycle handgrip 30. A plurality of
projections 33 having desired shapes, as discussed
previously, uniformly distributed on the tubular base 31 so
that by holding the handhold structure 60 of the present
invention, the hand 90' contacts and thus massaged by the
round projections 33.
It is apparent that although the invention has been
described in connection with the preferred embodiments,
those skilled in the art may make changes to certain
features of the preferred embodiments without departing from
the spirit and scope of the invention as defined in the
appended claims.
