Abstract
Abstract Disclosed is a magnetic top running toy wherein a spinning top is run along a running path. The magnetic top running toy includes a top having a magnetic shaft and a running path having a magnetic attraction wall adapted to contact with the magnetic shaft of the top when the top runs along the running path. The running path is constructed as a reciprocative running path permitting the top to turn at both ends thereof. A starting station and a jumping station are attached to the running path. The starting station has a guide surface for guiding the top onto the running path. The jumping station is adapted to allow the top guided from the running path to fly therefrom while keeping the top to spin.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
147 words
A magnetic top running toy assembly wherein a spinning top is run along a predetermined running path, comprising: a top having a magnetic shaft; a running path having a magnetic attraction wall adapted to contact with said magnetic shaft of said top when the top runs along the running path; a starting station attached to said running path and having a guide surface for guiding said top onto said running path; and a jumping station attached to said running path including means for directing said top, while spinning, to a specific location, and means for impacting said spinning top at said specific location with sufficient force to propel it into the air including a lever mounted to transfer force to the bottom of a spinning top to propel said top into the air upon the application of an impacting force downward upon the said lever's exposed end.
Claim 2
Dependent Claim
147 words
A magnetic top running toy assembly wherein a spinning top is run along a predetermined running path, comprising: a top having a magnetic shaft; a running path having a magnetic attraction wall adapted to contact with said magnetic shaft of said top when the top runs along the running path; a starting station attached to said running path and having a guide surface for guiding said top onto said running path; and a jumping station attached to said running path including means for directing said top, while spinning, to a specific location, and means for impacting said spinning top at said specific location with sufficient force to propel it into the air including a lever mounted to transfer force to the bottom of a spinning top to propel said top into the air upon the application of an impacting force downward upon the said lever's exposed end.
Claim 3
Dependent Claim
21 words
The invention of claim 1 further including means for receiving said impacted spinning top after it is propelled into the air.
Claim 4
Dependent Claim
32 words
The invention of claim 1 wherein said means for directing includes a pivotal changeover member that can be positioned across said running path to direct said spinning top to said specific location.
Claim 5
Dependent Claim
25 words
The invention of claim 2 wherein said means for receiving includes a receiving board with a spiral guide protrusion mounted vertically higher than said path.
Claim 6
Dependent Claim
40 words
The invention of claim 2 further including a movable member positioned adjacent the means for receiving and having a magnetic plate for contacting and attracting said spinning top with sufficient force to lift it off of the means for receiving.
Claim 7
Dependent Claim
18 words
The invention of claim 5 further including means for rotating the movable member to release the spinning top.
Claim 8
Dependent Claim
38 words
The invention of claim 3 further including a bias spring for forcing the changeover member to a retracted position and a lever connected to the changeover member and operable by an operator to subjectively contact the spinning top.
Claim 9
Dependent Claim
32 words
The invention of claim 2 further including a movable member positioned adjacent the path and having a magnetic plate for contacting and attracting the spinning top with sufficient force to lift it.
Claim 10
Dependent Claim
18 words
The invention of claim 8 further including means for rotating the movable member to release the spinning top.
Claim 11
Dependent Claim
100 words
In a toy spinning top assembly having a path defining a plane of travel for directing the relative translation of a spinning top, the improvement comprising: a jumping station cooperatively associated with the path including means for isolating the top from movement along the path and means for imparting sufficient force to propel the top into the air away from the plane of the path comprising a lever mounted to transfer force to the bottom of a spinning top to propel said top into the air upon the application of an impacting force downward upon the said lever's exposed end.
Claim 12
Dependent Claim
