Definitions

  • the present invention relates to a torso support device for supporting a torso of an operator of a machine.
  • the present invention relates to a torso support device for cyclists with disabilities in their upper bodies.
  • Torso support devices have been developed in order to enable e.g. cyclist with disabilities to operate a bicycle more easily.
  • a few known solutions for providing chest and/or body support are presented in the following.
  • US6076846 discloses a bicycle chest rest system for abating the weight from the arms, legs and feet of a cyclist.
  • the construction attaches to the top tube of the bicycle frame and is thereby adjustable longitudinally and vertically by virtue of a curved rail system.
  • the construction maintains a forward position, ideal for road cycling and time trailing, by supporting the upper torso or chest of the cyclist.
  • this design does not support a cyclist in an upright position or prevent forward motion in a comfortable manner under braking.
  • the rigid nature of the construction means that movement of the upper body and comfortable fitting is difficult, making it problematic for a user with limited mobility to get on and off.
  • US5383677 discloses a body support structure similar to US 6076846 attached to the top tube of a bicycle and extending almost perpendicular upwards.
  • the structure is height adjustable by means of a sliding arrangement and a rotatable leaver for locking it in place.
  • this system has the same disadvantages as US 6076846.
  • DE19644311 discloses a chest support structure that comprises of a fork attached to the top tube or head tube of a bicycle and a flexible belt or strap worn by the cyclist around the chest. This flexible strap attaches at two points on either side of the fork, and the cyclist is thereby attached to the construction.
  • the introduction of a flexible component means that shocks experienced by the cyclist are reduced, but the design still imposes the limitations in respect of access and comfort as US 6,076,846.
  • This design also provides primarily vertical support to the cyclist's chest.
  • US5326122 discloses a hinged bicycle chest support structure that attaches to the handle stem of the bicycle and is movable between a first position under the cyclist's chest and to a second non-use position away from under the cyclist. The cyclist is set at a forward position, and the difficult access and positioning of the support construction means that it not suitable for disabled individuals with reduced strength in the arms.
  • At least one embodiment of the present invention provides a torso support device that overcomes or reduces one or more of the problems arising in the prior art.
  • At least one embodiment of the present invention seeks to improve control for individuals with physical disabilities in their upper body, such as finger and arm amputees, individuals with upper limb dysmelia, or individuals with reduced muscular strength and/or motor function, and also for individuals who prefer to offload their arms for more comfortable cycling, such as individuals with muscular and skeletal disorders or arthritis.
  • individuals with physical disabilities in their upper body such as finger and arm amputees, individuals with upper limb dysmelia, or individuals with reduced muscular strength and/or motor function
  • individuals who prefer to offload their arms for more comfortable cycling such as individuals with muscular and skeletal disorders or arthritis.
  • the present invention provides a device for supporting a torso of an operator of a machine during operation, the machine being one of a handlebar-controlled vehicle or an exercise machine, the device comprising : a torso plate for contacting the torso of the operator of the machine; and a support frame for supporting the torso plate with respect to the machine in a position that resists and/or prevents forward movement of the operator relative to the machine.
  • the above device provides support to the operator of the machine against forward movement with respect to the machine, for example, in the case of a vehicle, when braking heavily or on bumpy terrain. This support provides two functions.
  • a disability support device for supporting the torso of an operator of the machine during operation, where the operator has an upper body disability.
  • the position of the torso plate is such that the operator of the machine is in a generally upright position during operation, for example such that the torso of the operator is supported by the plate at an angle of at least 30° with respect to horizontal.
  • Known torso support systems which have been briefly discussed above, have all targeted athletes when competing in a strenuous, substantially horizontal position.
  • the present device instead seeks to support a disabled person in a more natural cycling position.
  • the present device may thus also support the torso of the operator in a non- horizontal position.
  • the torso plate may provide support by receiving a compressive load from the weight of the operator's body, and preferably by transferring that load to a frame of the machine via the support frame by compressive and/or bending loads on the support frame.
  • the proposed system is hence considerably different to the use of straps or other harness type elements used to hold an operator securely in an upright seat.
  • the machine may have a seat without a backrest such that the torso plate provides the sole support for maintaining the operator in a seated position.
  • the device does not provide resistance against relative backward and/or sideways movement of the operator relative to the machine.
  • the device Whilst the device provides support against forward movement when the operator is in an upright position, in some embodiments the device may be adjustable so as to also provide support in other positions, such as a forward position, when adjusted to such a position.
  • the relative directions used herein should be understood as being with reference to the machine, such as a bicycle, in its normal orientation for operation. When used in respect of the device, these terms should be understood as being with reference to the device when mounted to the machine in its normal orientation for operation. Particularly, the terms “forward”, “backward”, “left” and “right” refer to directions relative to the operator of the machine when operating the machine. The terms “vertical” and “horizontal” refer to these directions when the machine is in its normal orientation for operation.
  • the device preferably enables operation of the machine without the weight of operator being supported by their arms.
  • Known systems to date have not been designed for users suffering from upper body disabilities to use such machines without the use of their arms for support.
  • the torso plate is preferably positioned, at least partially, above the front of a seat of the machine and is shaped to extend upwards and forward, with respect to the machine, for example in a shape suitable for cycling in the case where the vehicle is a bicycle.
  • the plate comprises a soft face material for contact with the torso of the rider of the vehicle, for example comprising foam, rubber, leather or the like. As the plate will be supporting a significant portion of the operator's weight, it is desirable to use a soft face material for comfort to distribute their weight across the plate.
  • the torso support plate may be adapted to support both the abdomen and the chest of the operator. This further distributes the weight of the operator, as well as economically positioning the entire torso region, for example to assist in the case of an operator having weak upper body strength.
  • a width of the torso support plate, in the left- right direction of the machine is between 10 cm and 20 cm. In some embodiments, a length of the torso support plate, in a direction perpendicular to the width direction, is between 25 cm and 50 cm. These dimensions have been found to be suitable for most applications to support substantially the whole of the torso of the operator.
  • the machine is a bicycle, preferably a pedal bicycle, preferably having an adjustable seat, such as a vertically adjustable seat.
  • pedal bicycle should be understood to include at least road bicycles, mountain bicycles and indoor bicycles, e.g. exercise bicycles, training bicycles and the like.
  • the support frame is pivotally mountable to bicycle such that raising and lowering of the seat of the bicycle causes the support frame to pivot with respect to a pivot point such that the torso plate moves with the seat of the vehicle.
  • the torso plate moves with the seat such that, even when the seat is adjusted, the torso plate remains in the optimal, e.g. pre-set, position for the operator.
  • This allows, for example, the operator to mount the bicycle with the seat in a lowered position in which their feet may rest comfortably on the floor, and to subsequently then raise the seat to the optimal cycling position without needing to readjust the device.
  • the device is used with a bicycle having a dropper post
  • the above arrangement further allows the seat of the bicycle to be adjusted during cycling without the torso plate requiring readjustment. This is advantageous because different seat positions are optimal for different cycling conditions and terrain.
  • the present invention may also be seen to provide a device for supporting the torso of the user of a bicycle during operation, the device comprising : a torso plate for contacting the torso of the user of the bicycle; and a support frame for supporting the torso plate with respect to the bicycle, the support frame being pivotally mounted or mountable to bicycle at (at least) a first location such that raising and lowering of the seat of the bicycle causes the support frame to pivot about the first location such that the torso plate moves with the seat of the vehicle.
  • the support frame comprises an upper frame- portion connected to the torso plate, a middle frame-portion connected to the upper frame-portion, and a lower frame-portion connected to the middle frame- portion.
  • the lower frame-portion may then be adapted to be pivotally mountable to the bicycle at a first location
  • the middle frame-portion or the top frame-portion may adapted to be contactable with or mountable to the bicycle at a second location such that raising and lowering of the seat of the bicycle causes the support frame to pivot with respect to the first location such that the torso plate moves with the seat of the vehicle.
  • the contacting or mounting portion of the middle or top frame-portion may include either a connection that allows only pivotal movement, i.e. such that it restricts upwards and downwards movement with respect to the seat, or one that allows for pivotal movement and vertically upwards movement, i.e. such that it only restricts downwards movement, for example where the contacting portion comprises a groove engaged with a pin.
  • the device described above need not necessarily be formed separately from the bicycle, but may be formed integrally with, for example, the bicycle frame.
  • the present invention also provides, a bicycle comprising a frame, an adjustable seat and a device as described in the aspects above, optionally including any of the preferred features thereof, wherein the support frame comprises an upper frame-portion connected to the torso plate, a middle frame-portion connected to the upper frame-portion, and a lower frame-portion connected to the middle frame-portion; wherein the lower frame-portion is pivotally mounted to the frame of the bicycle at a first location; and wherein the middle frame-portion is connected, directly or indirectly as discussed above, to the seat of the bicycle at a second location such that raising and lowering of the seat causes the support frame to pivot with respect to the first location such that the torso plate moves with the seat of the vehicle.
  • the first location may be any location towards the front of the bicycle, for example within 30 cm of the head tube of the bicycle frame, but is preferably at the head tube and/or around the steering tube of the bicycle. This position gives a maximum rotation arm for the torso plate and hence minimizes unintended rotation of the plate as the seat height is increased.
  • the first location may alternatively be located for example at the top tube of the bicycle.
  • the lower frame-portion is pivotally mounted or adapted to be pivotally mountable to the bicycle via a tubular adaptor that is pivotally connected to the lower frame-portion and is adapted for connection, e.g. in a rigid and non-pivotal manner, with the head tube of the bicycle. This firmly fixes the device to the bicycle so that it cannot easily come away making the device safer. It also does not require any further modification to attach firmly to a conventional bicycle frame.
  • the second location is preferably a location fixed relative to the seat of the vehicle.
  • the second location is at a saddle or a seat post of the bicycle.
  • the middle frame-portion or the top frame-portion may be mounted or adapted to be mountable to the bicycle at the second location via an adjustable distancing device, the adjustable distancing device being adjustable so as to vary the location of torso plate with respect to the second location.
  • an adjustable distancing device allows the support device to move with seat, but also allows the height of the torso plate relative to the seat to be adjusted to a desired height for optimal support.
  • the distancing device may preferably vary the location of the torso plate with respect to the second location by rotation about the first location, when the device is mounted to the bicycle. This means that the distancing device does not allow for variation of the location in the horizontal, left-right direction.
  • the lower frame-portion and the middle frame-portion are preferably coupled together so as to be axially movable with respect to one another. This allows the frame to be resized to fit bicycles of different sizes and/or different users of the same bicycle.
  • the lower frame-portion and the middle-frame portion may be lockable so as to prevent further movement. This allows the support frame to be resized and then fixed to form a rigid frame.
  • the upper frame-portion and the middle frame-portion may be pivotally coupled together, preferably such that the orientation of the torso plate is adjustable, i.e. may be adjusted.
  • the orientation of the torso plate may be adjusted by adjusting the angle between the upper frame-portion and the middle frame-portion.
  • the pivotal connection between the upper frame-portion and the middle frame-portion may preferably be locked in at least two different positions. This allows adjustment of the torso plate to provide support at the desired location. This configuration further allows the support device to be collapsed for efficient storage and transportation when not in use.
  • the device may further comprise a control panel for operation of one or more machine functions that are positioned with respect to the torso plate so as to be actuated using the head, and preferably the chin, of the operator. This allows operation of machine functions without the use of the operator's hands. This is particularly important where the operator has an upper body disability and cannot use their fingers to control these functions.
  • the device may include buttons and/or levers positioned so as to be actuatable by the head or chin of the operator when their torso is supported by the torso plate.
  • the machine functions may include braking of the vehicle and/or changing gears of the vehicle.
  • One or both of these functions may be performed electronically, such as via an electronic braking system and/or an electronic gear-changing mechanism.
  • the machine functions may include raising and/or lowering of the seat of the machine, for example via a dropper seat post.
  • the torso support device herein makes it possible for individuals, aka operators, with disabilities in the upper body to use a regular machine, such as a two-wheeled bicycle. Similar designs have previously been developed with the objective of maintaining an aerodynamic position in time trial cycling, by reducing the stress on the arms and thereby reduce the energy consumption and fatigue. However, such designs still rely on upper body strength and/or the cyclist having two arms, and so are not suitable for individuals with disabilities in the upper body.
  • the torso support device herein provides for that weight may be completely, or almost completely, removed from the handlebars. In this manner, a bicycle is made steerable for disabled individuals having problems with holding a handlebar or controlling the steering of the bicycle.
  • the present invention may also be seen to provide a bicycle having mounted thereto a device as described above, optionally include any or all of the preferred features described.

  • the upper frame-portion 2 is pivotally connected to the middle frame- portion 3 by a joint 5, or a flexible connection, to allow adjustment of the angle between the upper frame-portion 2 and the middle frame-portion 3. Typically this is done with brackets and bolts.
  • An adjustment mechanism fixes the angle between the upper frame- portion 2 and the middle frame-portion 3 at a desired angle, and allows regulation when in an "open mode".
  • the adjustment mechanism may include, for example, a joint 5 that may be locked/fixed, and/or a strut 6 that fixes the distance between a point on the upper frame-portion 2 and a point on the middle frame-portion 3, such as a strut having an adjustable length or a fixed-length strut having adjustable attachment points between the strut and the upper frame-portion 2 and/or between the strut and the middle frame 3.
  • the upper frame-portion 2 and the middle frame-portion 3 may be made as one part or as non-adjustable parts, but the support frame 110 does not then have these adjustment options.
  • the middle frame-portion 3 may be connected to the top frame-portion 2 any place along the top frame, and not just at its bottom end, as shown in the Figures. This will not affect the function of the torso support plate 1 and, in some arrangements, different connection points between the upper frame- portion 2 and the middle-frame portion 3 may allow for improved suspension solutions for the torso support plate 1 in the forward direction.
  • the support frame 110 is relatively rigid, but may include some flexibility in the connection between the torso support plate 1 and the upper frame- portion 2 or in the connection between the upper frame-portion 2 and the middle frame-portion 3, which provides some damping to improve comfort.

  • the weight of the rider forces the support structure downwards and forwards when the rider leans on the torso support plate 1 under deceleration, such as when breaking or when the wheels hits an obstacle.
  • a hinged mounting of the support frame 110 to the bicycle make it possible to have the torso support plate 1 automatically follow the height adjustments of the seat, and maintain the right position of the torso support plate 1 relative to the torso of the cyclist for all seat heights. In this way, the rider is always provided with optimal support, regardless of the seat height.
  • the frame allows the user to mount the bicycle with the seat in a dropped position, and to subsequently raise the seat to an optimal riding position. Furthermore, especially when using a dropper post, this is an advantage as the seat may be adjusted during cycling to achieve the optimal position for the terrain at that time, for example when riding down steep hills, a low seat and low center of gravity is favorable.
  • the torso support plate 1 and the support frame 110 are easily foldable by virtue of the pivotal connection 5 between the upper frame-portion 2 and the middle frame-portion 3, making the device 100 easy to transport and store.
  • the same model may fit a large number of users and bicycles, increasing the production volume and reducing cost, as well as making the device 100 more accessible than tailor- made solutions for individual cyclists.
  • the present invention has been described with reference to certain preferred embodiments, it will be appreciated that these embodiments are set forth by way of example only and that the scope of the present invention is not limited thereto, but includes all embodiments falling within the scope of the claims.
  • the present invention is not limited to road and mountain bicycles, but may also be used with the same objective for other applications, such as indoor bicycles or motorbikes.
  • the advantages of the present invention are believed to be present for any vehicle in which the vehicle is controlled by rotation of the handlebars about an axis perpendicular to the forward -rearward direction of the vehicle, such as using a handlebar.
  • the present invention may also be applied to exercise machines, such as indoor bicycles and elliptical trainers, where it is desirable not to support the operator's weight on their arms.
