ABSTRACT:

This invention relates to a pogo stick and, more particularly, to a pogo stick which provides a distinctive indication (e.g. a distinctive sound) when operated.
BACKGROUND OF THE INVENTION
Pogo sticks have been in existence for some time and provide a distinct challenge to children, particularly to children of advanced age, when operated. To operate a pogo stick, a child steps on a foot rest on a housing on the pogo stick, grasps a handle on the housing and hops through successive iterations to progressive positions until the child loses his or her balance. It is a challenge to a child to be able to hop on the pogo stick through a number of successive iterations without having to jump from the pogo stick because of a loss of balance.
In spite of the challenges offered by the pogo stick, children are constantly looking for new sensations while operating the pogo stick. These new sensations enhance the thrill which the children experience while operating the pogo stick. Such new sensations would be particularly desirable if they provide in some way an instantaneous indication of the number of successive hops experienced by a child during an operation of the pogo stick before the child loses his or her balance.
BRIEF DESCRIPTION OF THE HOUSING
In one embodiment of the invention, a pogo stick includes (a) a housing, (b) a member movable within the housing, (c) a spring retained at opposite ends by the housing and the member and compressible upon the actuation of the member to a support surface (e.g. ground) and expansible upon the movement of the member from the support surface, (d) a handle on the housing near the housing top and (e) a foot rest on the housing near the housing bottom. A switch normally in an open relationship is operative to (a) a closed relationship upon the actuation of the member to the support surface and (b) an open relationship upon a movement of the member from the support surface. The switch includes a resilient electrically conductive element and a stationary electrically conductive element normally defining an open relationship. The resilient member is movable in response to the member actuation to the support surface to engage the stationary element and to provide a switch operation in the closed relationship.
The resilient element extends beyond a supporting stud for pivotable movement relative to the stud and the stationary element to engage the stationary clement upon the member actuation to the support surface. An indicator responsive to the switch operation provides an indication (e.g. distinctive sound) after each particular number of switch operations. The switch and the indicator are disposed within a casing supported by the housing. A reset within the casing is connected to the counter to initialize the count when manually operated.
