Description
SPECIFICATION
Control device
The present invention relates to a control device and more particularly to a control device which includes means for controlling electrical or electronic apparatuses such as computers or electronic games whilst providing exercise for the user.
The recent upsurge in the availability of home computers and their use for playing games has certain attendant problems. Many people, particularly children, spend long periods of time playing such games and the only physical exercise that this provides is in operating the keyboard or joystick manually.
The present invention therefore seeks to provide a control device which incorporates means for controlling electrical devices such as computers and electronic games but which simultaneously provides the game player with physical exercise.
According to the present invention there is provided a control device for operating an electrical or electronic apparatus and for providing exercise for a user comprising a top-plate member on which, in use, the user stands, the top plate member being locatable on a base member, a plurality of contact means for selectively establishing a desired electrical contact between the base member and the top-plate member, the selection of the desired electrical contact being determined by the location of the weight of the user and the region of the top-plate through which said weight acts and means for transmitting the signal from the desired electrical contact to the electrical or electronic apparatus.
Preferably, the top-plate member is separable from the base member.
Desirably, the base member comprises a control plate and a base structure connected to the control plate by a plurality of spring members, a plurality of electrical contact plates being disposed on one of said control plate or base structure and electrically conductive means being disposed on the other of said control plate or base structure and in which the means for transmitting the signal comprises a plurality of electrical leads and an electrical output.
Advantageously the top-plate member comprises a first plate member upon which, in use, the user stands and a balance plate.
Further preferably the balance plate is arcuate and includes a detachable, substantially hemispherical projection portion and the control plate is arcuate and has a radius of curvature selected such that the balance plate lies on the control plate, the control plate including a deformation which, on one side, defines a substantially hemispherical recess for receiving the projection portion of the balance plate and, on the other side, a substantially hemispherical projection portion, the base structure including a concave upper surface portion including a centrally disposed hemispherical recess for receiving the hemispherical projection portion of the control plate, the radius of curvature of the concave upper surface portion being so selected that the control plate and balance plate can tilt thereon when the hemispherical projection portion of the control plate is located in the recess in the base structure.
Further desirably the contact plates are disposed on said concave upper surface of the base structure and extend radially to cause contact between the control plate and the contact plate to take place along a line of engagement.
Further advantageously a peripheral groove is provided on the base structure, the spring members each engaging, at one end, in the peripheral groove and, at the other end, engaging on the periphery of the control plate.
Stili further preferably, the substantially hemispherical projection portion is detachable and replaceable by a fitment terminating flush with the arcuate lower surface of the balance plate.
The invention will be further described, by way of example, with reference to the accompanying drawings, in which:

In Fig. 1 of the drawings, there is shown an exercise device which comprises a top-plate and a remote control device for operating a computer or electronic game. The remote control device comprises a control plate 11, a base member 12, a plurality of electrical contact plates 13, a plurality of springs 14, electrical connectors 15 and 16 and an electrical connection device 17.
The top-plate comprises a first plate member 21 on which a user stands, balance plate 22, and a hemispherical projection 23. The top-plate can be seen more clearly in Fig. 2.
The remote control device is best seen in Figs. 3-1 and 3-2 and comprises a base member 12 which is intended to be located on the ground. The upper surface of the base has a concave depression formed therein. In the centre of the depression, a hemispherical recess 18 is provided. The recess 18 receives a correspondingly hemispherically-shaped hollow projection member 28 formed on the underside of the control plate 11. Around the periphery of the upper surface of the base member 12, an annular groove 19 is formed. A plurality of springs 14 are disposed in this groove, one end of each spring 14 being attached to the wall of the groove and the other end thereof being attached to the periphery of the control plate 11.
In the base of the depression, a plurality of contact plates 13 extending radially inwardly towards the recess 18 are provided, as is best seen in Fig. 4. These plates 13 are connected, by electrical leads 15, 16, to an output 17 in the form of, for example, a socket.
The control plate 11 has a convex lower surface having a different radius of curvature to that of the depression in the upper surface of the base member 12. As mentioned hereinbefore, the underside of the plate 11 has a hollow hemispherical projection 28 formed thereon. The projection 28 receives the hemispherical projection 23 forming part of the top-plate assembly.
In the non-use position, as shown in Fig. 3-1, the projection member 28 of the control plate 11 is located in the recess 18. The control plate 11, which includes electrically conductive means, is otherwise maintained out of contact with the remote control device, particularly the contact plates 13 by the action of the springs 14. However, when a user steps onto the first plate member 21, this member 21 tilts thereby forcing electrically conductive means on the control plate 11 into contact with one of the contact plates 13 along a line of engagement, as will be discussed in greater detail hereinafter with reference to Fig. 8. This is, therefore, an electrical switch and such tilting causes closing of the switch, as is shown in Fig. 3-2.
Fig. 8-1 is a sectional view of the device in accordance with the present invention in its balanced or non-use position. Once a user steps onto the first plate member 21, this will cause the control plate 11 to tilt and the control plate 11 will contact with the contact plate along a line of engagement. In Fig. 8-2, there is shown a circle which represents the upper plan view of depression in the base. 0 represents the centre of the control plate 11 in its balanced or nonuse position, 0' represents the centre of the control plate 11 when the control plate 11 is in contact with a contact plate 13 and F and G represent arbitrary points on the rim of depression.
The projections of O'G and O'F intersect the circle shown in Fig. 8-2 at points G', G", F' and F".
The circle in Fig. 8-3 has a radius corresponding to that of the control plate 11. The projections of O'G and O'F are combined with the projection of O'P where P is a point of contact of the control plate 11 with the contact plate 13, to be coincident, as is shown in Fig. 8-3, so that
GZ=GP and FW=FP. The lines from F and G in Fig. 8-3 intersect with the projection lines from
F', G', F" and G" in Fig. 8-2 at points F', G', F" and G" in Fig. 8-3. By drawing a line connecting G', F', P, F" -and G" in Fig. 8-3, an arc for the line of contact of the contact plate 13 with the control plate 11 is defined. Thus, the control plate os capable of engaging completely with the spherical surface of the base as exemplified in Fig. 3-2.
From the above, it will be apparent that the control plate engages with the part-spherical recess in the base along a line. The radially extending contact plates 13 are symmetrically disposed on the part-spherical surface of the base, as is shown in Fig. 4. Thus, the control plate 11 engages with only one of the plurality of contact plates 13 at any one time. Accordingly, a user who steps onto the plate member 21 can cause the control plate to tilt in any desired direction so as to cause it to engage with a desired one of the contact plates. The control plate is G'T distant from G' or F'S distant from F'. The formula for calculating the distances G'T and
F'S shown in Fig. 9 will now be detailed.
Assuming that:
O' is the centre of the control plate 11 at (0,0) coordinates;
D is the centre of the contact plate 13 at (A,B) coordinates;
r is the radius of the control plate;
R is the radius of the contact plate;
P is the contact point of the control plate and the contact plate;
G' is a point on the contact plate at (X,Y) coordinates;
m is the gradient tan Q (see Fig. 5-1); and
d is a distance between the circles representing the control plate and the contact plate; then (X-A)2+(Y-B)2=R2 and Y=mX.
(X-A)2+(mX-B)2=R2 or X2-2AX+A2+m2X2-2mXB+B2-R2=O by rearranging, (1 + m2)X2-2(A + Bm)X+ (A2+ B2- R2) =0
Fig. 2 is a perspective view of a top-plate member which is exemplified in Fig. 5-1. A user can utilise this member separately from the remainder of the device if this is desired. To do this, the hemisphere 23 is placed in contact with the ground and the member rotated. The hemispherical surface can contact the ground at any point of the surface. The contact point P of the top-plate member with the ground constantly changes as the top-plate spins and tilts as is exemplified in Fig. 5-1. Thus, the vertical line from P, shown as PH automatically moves to pass through the centre of gravity G of top-plate member.The ability to change the contact point P makes the invention of the top plate more stable and better for spinning, and hence better as a balancing device than known arrangements such as that shown in Fig. 5-2. The known top-plate member shown in Fig. 5-2 only contacts the ground at a single point P. In this arrangement the vertical line PH moves away from the centre of gravity G while the top-plate member is spinning and tilting. Accordingly, it is somewhat unstable and will topple once the top-plate member has tilted more than a few degrees.
Thus, if
Q is the angle of tilt;
P is the point of contact;
PH is the vertical line through the contact point P;
G is the centre of gravity of the top-plate;
fx is the force of gravity acting on the top-plate shown in Fig. 5-1,
dx is the horizontal distance of the centre of gravity from the vertical line PH:
Fx is the force of gravity acting on the known top-plate shown in Fig. 5-2; and
Dx is the horizontal distance of the centre of gravity (G) from the vertical line PH of the known
top-plate;
then fx=Fx, and Dx > dx, hence fx. dxtfx. Dx
Fig. 6 is a sectional view of a modified form of the invention in which the top-plate is different. The central hemispherical portion 23 shown in Figs. 2 and 5-1 is made detachable and is replaced by an insert member 24 which terminates flush with the underside of the balance plate 22.A user stands on the plate 21 and, by moving his feet, causes the top plate to rotate. If desired, one point on the plate may be caused to contact the ground and then a different point is caused to contact with the ground. By so doing, the user can move the plate in any desired direction. If two arbitrary points N and S contact with the ground interchangeably and the displacement angles are varied, the plate will move in different directions.
Fig. 7 is a movement analysis of these points N and S. N and S are two contacting points and N' and S' are contacting points after the plate has been moved. The displacement angles are denoted by x and y. NN' and SS' are the distances moved by the N and S points respectively.
The distances moved can be calculated as follows, referring to Fig. 7:
x
NN'=2MN=2NS sin- 2
y
SS'=2ST=2NS sin- 2
Thus, if angle x equals angle y, then NN'=SS', the N and S points are moving in the same direction but if angle x is less than angle y, then NN' < SS', and the N and S points are moving in different directions and the plate is rotated.
Since the points of contact of the plate with the ground are changed occasionally whilst the user is changing the forces applied by his feet, the twist-plate remains balanced. If Z is the contact point, Fx is force applied by the right foot at point X and Fy is force applied by the left foot at point Y, then because the plate is balanced, Fx XZ=Fy YZ. Thus the plate will always be balanced irrespective of the forces applied. The user can therefore twist his body, turn the plate back and forth and move the plate whilst keeping the plate balanced.
