Abstract

A pedal assembly (e.g. as a brake input into a computer driving simulation game) has a pedal head 101 linked to a potentiometer, with maximum travel stops 106,305, restoring means (e.g. elastomer or spring 200) and at least one adjustable compressible stop 104,303 to give feel to the pedal. The stops may be adjusted with e.g. a screw tread, slidable mountings, adhesive or hook and loop fastenings. Compressible stops may have rubber portions that are tapered (fig 4a); rounded or flat (fig 4b); cylindrical (fig 4c) or of an elongate wedge shape (fig 4c), and engage a profiled pedal arm (102, fig 5). A cable adjuster 203 may also adjust the feel, and the pedal may slide rather than pivot. Three pedals may be adjustably mounted in a frame (fig 6) to simulate accelerator, brake and clutch pedals.

Description

PEDAL DEVICE
Field of the Invention
The present invention relates to a pedal device, and in particular, although not exclusively, to a pedal device configured for use with a computer programme.
Background to the Invention
For use in simulation games, in particular driving simulation games, it is known to use pedal-style computer input devices to allow a user to experience a To more realistic simulated driving experience. Typically, such pedal-input devices are based around the design of vehicle pedals where a user depresses the pedal by application of pressure by a foot to a pedal head.
Various forms of pedal input device exist, in particular brake pedal input devices, operating by a variety of actions in an attempt to simulate a feel of a real-life vehicle brake pedal. Examples can be found in US 5,116,051, FR 2682508, CA 2,146,839 and BE 1002625.
In particular JP 2002049432, in an attempt to simulate a real-life brake pedal, employs a rubber resistor connected through a shaft to a pedal such that the rubber is compressed by a user stepping on the pedal.
The inventors have identified various problems associated with prior art pedal devices. In particular, the major disadvantage associated with such prior art brake pedal devices is their unrealistic feel. As driving games and simulators become more sophisticated greater demand is placed on pedal, and in particular, brake input devices to replicate, near exactly, the feel and sensitivity of real-like vehicle pedals. For example, the change in feel of a brake pedal from initial pressure application through to wheel locking.
Due to a lack of mechanical adjustment associated with prior art brake pedal input devices a user cannot tailor the feel of the brake pedal to a sufficient degree so as to simulate the feel of a variety of real-life vehicle braking systems, for example formula one or road saloon car. Additionally, prior art pedals are relatively complex in construction having excessive moving parts and components. This leads to both expensive production costs and end sale price.
Excessive maintenance and short product lifetimes are further disadvantages
associated with complex prior art pedal systems.
To What is required therefore is a pedal input device, and in particular a brake pedal input device of relative simple design having a high degree of adjustment so as to allow a user to simulate, almost exactly, the feel associated with a variety of real-life vehicle braking systems.
:5 Summary of the Invention
On realising the disadvantages associated with prior art pedal devices, the inventors provide a brake pedal configured for use with computer programmes and in particular vehicle driving computer games and simulations. The brake pedal computer input device comprises a simple design involving minimal moving go parts and components whilst achieving maximum realism and feel simulation when compared with that of real-life vehicle braking systems. Due to the! construction of the brake pedal system, disclosed herein, complete adjustment or alteration of the feel of the simulated braking action is achieved, not being restricted to discreet pre-set component positions as is common with typical prior art brake pedal simulator input devices.
In a specific implementation, the brake pedal comprises a displaceable brake pedal engaging arm being optionally pivotally mounted at one end.

Detailed Description
There will now be described by way of example a specific mode contemplated by the inventors. In the following description numerous specific details are set forth in order to provide a thorough understanding. It will be apparent however, to one skilled in the art, that the present invention may be practiced without limitation to these specific details. In other instances, well known methods and structures have not been described in detail so as not to
unnecessarily obscure the description.
Specific implementations of the present invention are aimed at a brake pedal system configured to simulate, near exactly, a plurality of different real-life vehicle braking systems. The brake pedal disclosed herein is design specifically to simulate real-life brake systems with regard to feel and adjustability. A realistic o brake pedal feel is achieved through simple construction and minimal component parts whilst allowing a vast degree of component adjustability so as to achieve and provide a brake pedal configured to simulate a plurality of different vehicle braking systems.
The present invention utilises at least one compressible stop being configured to interface with a displaceable pedal engaging arm whereby a user applying pressure to a pedal head, connected to the engaging arm, experiences resistance due to compression of the compressible stop by the engaging arm. As the rubber stop is not connected directly or indirectly to the engaging arm an unrestricted, smooth and progressive resistance is experienced by a user, such o resistance not being effected by intermediate component parts.
A considerably sensitive braking system is thereby provided due to the free and direct engaging of the compressible stop by the engaging arm.
According to specific implementations of the present invention the compressible stop is infinitely adjustable relative to the engaging arm with regard to relative positioning, orientation, size and shape (such adjustments being none exhaustive). Through the utilization of a plurality of compressible stops, positioned opposed to the engaging arm, along a length of the engaging arm, a So vast number of resistance configurations may be achieved. As detailed below, variation of the relative distance between the compressible stop and the engaging arm, the angle of orientation of the compressible stop relative to the engaging arm and the shape and size of the compressible stops may be individually adjusted so as to achieve the desired resistance response and feel of the brake pedal.
Referring to Figure 1 herein there is illustrated a side elevation view of the brake pedal 100 comprising a brake pedal head 101; an engaging arm 102; pivot means 103; at least one compressible stop 104; pedal head support arm 105; 3 o maximum travel stop 106 and base 107.
According to a specific implementation of the present invention pedal support head 101 is adjustably connected to engaging arm 102 via support arm and adjustment means 109. Accordingly, pedal head 101 may be adjustably positioned, including pivotally mounted, relative to engaging arm 102 (including angle of displacement from and position along, engaging arm 102).
Displaceable engaging arm 102 is pivotally mounted, substantially at one end via pivot means 103, engaging arm 102 and pedal head 101 being configured to pivot about pivot means 103 along arc 108.
Being positionally opposed to engaging arm 102 there is provided compressible stop 104, optionally being a rubber stop. Stop 104 is adjustably positioned in a stop mount (not shown) being formed on or integrally with base 107, stop mount providing adjustable placement of stop 104 relative to engaging arm 102.
Maximum travel stop 106 is provided to arrest displacement of pedal 100 at a maximum displacement. Additionally, maximum travel stop 106 is adjustably positioned within the stop mount as detailed with reference to stop 104.
In operation, a user applies a pressure to pedal head 101 via a foot, such an applied pressure being transferred to the engaging arm via support arm 105.
A leading edge or surface 110 is then brought into contact with stop 104 such that with the continuation of applied pressure, stop 104 is compressed providing a resistive/reactive force to the applied pressure.
The feel experienced by a user when exerting pressure on pedal head 101 may be varied considerably by adjustment of the following non-exhaustive list including a distance between engaging arm 102 and stop 104; a relative positioning of stop 104 along the length of engaging arm 102 relative to pivot so means 103; an orientation alignment of stop 104 relative to an axis along the length of engaging arm 102; a composition of stop 104; a shape of stop 104; a size of stop 104; a multiplicity of stop 104; a size of engaging arm 102; a shape of engaging arm 102 and in particular a shape and size of leading edge 110.
As will be appreciated by those skilled in the art, and by way of example, the ease with which pedal head 101 may be depressed and the corresponding feel of the pedal system is directly dependent upon variation of the above parameters with regard to the engaging arm and the single stop or plurality of stops 104.
According to a further specific implementations of the present invention, the pedal assembly is configured for use in an inverted orientation such that engaging arm 102 is suspended from a structure being positioned above pedal 10O, e.g. a 180 rotation of Figure 1 herein.
Referring to Figure 2 herein there is illustrated a side elevation view of the brake pedal of Figure 1 herein further comprising restoring means 200; fixing means 201, 202 and pedal block floor 203.
According to the specific implementation of the present invention restoring means 200 is configured to restore pedal 100 to an initial position following a o decrease or termination of the applied pressure on pedal head 101. According to the specific implementation, restoring means 200 comprises a spring however any other suitable elasticated means may be employed, for example, an elastomer or similar. Accordingly, the feel and operation of the pedal 100 may be adjusted further by adjustment of restoring means 200 at fixing means 201 and/or 202. For example, the position of fixing means 202, 201 may be adjusted on floor 203 and engaging arm 102.
One or a plurality of restoring means 200 may be employed within the pedal braking system so as to provide a variation of feel when depressing and releasing o pedal head 101.
Referring to Figure 3 herein there is illustrated a side elevation view of a further specific implementation of the present invention as detailed with reference to Figures 1 and 2 herein comprising stop mount 300; stop mount fixing means 301, 302; compressible stop 303; cable adjuster 304; return stop 305 and means for stop adjustment 306.
As detailed with reference to Figures 1 and 2 herein a plurality of stops 104, 303, 106 are adjustably mounted at a stop mount BOO, stop mount 300 being releasably or permanently attached to base 107 via mount fixing means 301, To 302. Return stop 305 is provided at the interface between pedal block floor 203 and the trailing edge or surface of engaging arm 102 so as to prevent restoring means 200 bringing engaging arm 102 into contact with floor 203. Stop 305 is also adjustably positioned relative to floor 203 so as to provide adjustment of the length of travel of engaging arm 102 following applied pressure to pedal head 101.
According to specific implementations of the present invention pivot means 103 may include a potentiometer being configured to convert displacement or movement of engaging arm 102 into an electrical signal being input into a To computer or similar device allowing use of the pedal system within the simulator programme. As will be appreciated by those skilled in the art, a plurality of different types of potentiometer are usable with the present invention including, for example, radial or sliding potentiometers. Additionally, restoring means 200 may be positioned at pivot 103 thereby avoiding use of restoring means 200 and s fixing means 201, 202 as detailed with reference to Figures 2 and 3 herein.
Figure 3 illustrates a plurality of compressible stops 104, 103 being adjustably positioned at stop mount 300. According to the specific implementation of the Figure 3 herein means for stop adjustment 306 are o provided in stop mount 300 adjustment being possible via screw threads formed on stop support arm 307. According to further specific implementations of the present invention the height, position and orientation of stops 104, 303, 106 may be selectively adjusted by any suitable means for stop adjustment. For example, the compressible stops may be slideably mounted within stop mount 300 thereby stops are not restricted to discreet positions along stop mount 300. Alternatively, the stops may be displaceable affixed by suitable hook and loop type fasteners such as non-permanent adhesives to an upper surface of stop mount 300 and/or base 107 as detailed with reference to Figures 1 and 2 herein. Any other suitable releasable affixing means may be employed.
Further adjustment of the pedal travel and feel is possible via cable adjuster JO 304 influencing pedal depression and return in addition to that provided by adjustment of restoring means 200.
According to further specific implementations of the present invention pedal head 101 is connected directly to engaging arm 102, engaging arm 102 being slidably mounted using suitable sliding mount means. For example, pedal 100 may be slidably depressed onto compressible stop 104. Adjustment of the pedal head on engaging arm 102 may be possible directly or may involve the use of a pedal support arm 105.
so Where the potentiometer is mounted remotely from pivot means 103, the return force associated with the radial or sliding potentiometer provides an additional return force to that given by restoring means 200. Consideration of the combined restoring force is therefore included herein.
Referring to Figures 4a, 4b, 4c and 4d herein there is illustrated perspective views of different compressible stop configurations. Figure 4a herein illustrates a substantially tapered rubber stop having a single leading edge 401. Accordingly, stop 400 and in particular leading edge 401 may be aligned via stop mount 300, in a substantially perpendicular direction to a length of engaging arm 102.
Alternatively, leading edge 401 may be substantially transverse to a length of engaging arm 102 thereby providing a different degree of resistance following engagement by leading edge 110 of engaging arm 102. The degree and size of the taper of stop 400 may be adjusted so as to provide further resistance adjustment.
Figure 4b herein illustrates a further specific implementation of a compressible stop 402 comprising a substantially flat or slightly rounded engaging portion 403. Figure 4c herein illustrates a further specific implementation of a compressible stop 404 having a generally cylindrical configuration. Figure 4d herein illustrates a yet further specific implementation of compressible stop 405 being configured to extend along a length of engaging JO arm 102. Stop 405 may comprise a wedge-like configuration so as to provide greater adjustability and feel variation in keeping with the spirit of the present invention.
As will be appreciated by those skilled in the art, the present invention is not restricted to utilization of specific stops as detailed with reference to Figures 1 to 4d herein. Moreover, a composition of the compressible stop(s) may be selectively adjusted so as to increase adjustment to the feel of the pedal system.
Referring to Figure 5 herein there is illustrated a front end elevation view of 2 o the brake pedal as detailed with reference to Figures 1 to 3 herein. In operation, brake pedal head 101 is depressed by a user 500 whereby engaging arm 102 engages onto stop 104. The leading edge 110 of arm 102 may be adjusted to effect the way by which engaging arm 102 engages stop 104. As detailed with reference to Figure 5 herein engaging arm 102 comprises a substantially square section, arm 102 being a hollow material such as, for example, steel, a metal alloy or similar hard material. Additionally, leading edge 110 may be profiled or varied in shape and dimension along a length of engaging arm 102 so as to increase the degree of adjustment of feel of the brake pedal. Further specific implementations of engaging arm 102 include a substantially triangular, diamond or elliptical cross-section, in turn, providing various leading edge profiles.
Referring to Figure 6 herein there is illustrated a plan view of a pedal block assembly including brake pedal 100 as detailed with reference to Figures 1 to 5 herein comprising accelerator 606; clutch 607 and brake position adjustment means 602 and 603. By mounting brake pedal 100 on frame 600 and in particular rails 601 a lateral displacement 604 of brake pedal 100 may be achieved. Additionally, a displacement front to back is also possible via adjustment means 605, adjustment means 603 optionally being formed in cooperation with pivot means 103.
