Abstract
Abstract A coordination-practice device comprising a table mounted for tilting movement about a horizontal axis and for rotation about an axis perpendicular to its surface, the movements being simultaneously and independently effected by movement of respective controls operable by an operator to control the motion of an object along a path defined on the table surface. The rotation is controllable by a manually operable wheel and the tilting either by a manual control or by two independent, foot-operable pedals, the use of which simulates the simultaneous use of the clutch and accelerator pedals of a motor vehicle.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
187 words
A driving practice device, comprising: a base, a table carried by the base and having a flat upper surface, said table being tiltable about a substantially horizontal axis and rotatable about an axis substantially perpendicular to the table; a manually operable steering wheel carried by said base and connected to said table such that the manual rotation of said wheel effects rotation of said table about said axis; two substantially vertical push-rods which act on an under-surface of said table, one on either side of said axis of rotation of the table, to apply opposite turning moments to said table; two foot-operable levers pivotally carried by said base, one end of each of which acts on a respective push-rod to force it upwards in response to pressure on the opposite end of said lever, to tilt said table; and a movable object which can be placed on said flat upper surface for sliding or rolling movement along it, operation of said steering wheel and said foot-operable levers to rotate and tilt said table controlling the speed and direction of movement of said object relative to said surface.
Claim 2
Dependent Claim
187 words
A driving practice device, comprising: a base, a table carried by the base and having a flat upper surface, said table being tiltable about a substantially horizontal axis and rotatable about an axis substantially perpendicular to the table; a manually operable steering wheel carried by said base and connected to said table such that the manual rotation of said wheel effects rotation of said table about said axis; two substantially vertical push-rods which act on an under-surface of said table, one on either side of said axis of rotation of the table, to apply opposite turning moments to said table; two foot-operable levers pivotally carried by said base, one end of each of which acts on a respective push-rod to force it upwards in response to pressure on the opposite end of said lever, to tilt said table; and a movable object which can be placed on said flat upper surface for sliding or rolling movement along it, operation of said steering wheel and said foot-operable levers to rotate and tilt said table controlling the speed and direction of movement of said object relative to said surface.
Claim 3
Dependent Claim
40 words
A driving practice device according to claim 1, wherein said table can be tilted through an angle of up to a maximum of 30° in either direction from a position in which the surface of said table is substantially horizontal.
Claim 4
Dependent Claim
42 words
A driving practice device according to claim 1, wherein raised edges are provided on said upper surface of the table to define a path along which said movable object can be maneuvered by operation of said steering wheel and said foot-operable levers.
Claim 5
Dependent Claim
29 words
A driving practice device according to claim 1, wherein said base comprises at least two releasably engageable parts and wherein parts of the device are releasable from the base.
Claim 6
Dependent Claim
195 words
A coordination practice device, comprising: a base; a substantially horizontal arm carried by said base for rotation about its longitudinal axis; a table supported at one end of said arm for tilting about said longitudinal axis of said arm and for rotation about an axis substantially perpendicular to the table and to said longitudinal axis; a drive shaft supported at the opposite end of said arm to said table, such that pivotal movement of said drive shaft about said longitudinal axis of said arm, in either sense, is transmitted by said arm to tilt the table, said drive shaft being rotatable about its longitudinal axis; a manually operable wheel carried by said drive shaft such that rotation of said wheel effects rotation of said drive shaft about its longitudinal axis; a first pulley having a circumferential groove and adapted to be driven to rotate by said drive shaft; a second pulley incorporated in said table and having a circumferential groove, and a flexible drive belt engaged in said circumferential grooves in said first and second pulleys, to transmit drive from said first pulley to said second pulley on rotation of said wheel by an operator.
Claim 7
Dependent Claim
195 words
A coordination practice device, comprising: a base; a substantially horizontal arm carried by said base for rotation about its longitudinal axis; a table supported at one end of said arm for tilting about said longitudinal axis of said arm and for rotation about an axis substantially perpendicular to the table and to said longitudinal axis; a drive shaft supported at the opposite end of said arm to said table, such that pivotal movement of said drive shaft about said longitudinal axis of said arm, in either sense, is transmitted by said arm to tilt the table, said drive shaft being rotatable about its longitudinal axis; a manually operable wheel carried by said drive shaft such that rotation of said wheel effects rotation of said drive shaft about its longitudinal axis; a first pulley having a circumferential groove and adapted to be driven to rotate by said drive shaft; a second pulley incorporated in said table and having a circumferential groove, and a flexible drive belt engaged in said circumferential grooves in said first and second pulleys, to transmit drive from said first pulley to said second pulley on rotation of said wheel by an operator.
Claim 8
Dependent Claim
40 words
A coordination practice device according to claim 5, wherein said table can be tilted through an angle of up to a maximum of 30° in either direction from a position in which the surface of said table is substantially horizonal.
Claim 9
Dependent Claim
63 words
A coordination practice device according to claim 5, wherein the table has a flat upper surface and wherein said device includes a movable object which can be placed on said upper surface for sliding or rolling movement along it, operation of the wheel to tilt and rotate the table controlling the speed and direction of movement of said object relative to the surface.
Claim 10
Dependent Claim
37 words
A coordination practice device according to claim 7, wherein raised edges are provided on said upper surface of the table to define a path along which said movable object can be maneuvered by manipulation of the wheel.
Claim 11
Dependent Claim
29 words
A coordination practice device according to claim 5, wherein said base comprises at least two releasably engageable parts and wherein parts of the device are releasable from the base.
