Number 272839 Dated August 30,1995
I, HENRY ARTHUR HOPGOOD of 15 Blyth Street, Cromwell, New Zealand, a New Zealand citizen, do hereby declare the invention for which I pray that a patent may be granted to me, and the method by which it is to be performed, to be particularly described in and by the following statement.

This invention relates to an accessory for a bicycle.
272839
When riding a bicycle it is not unusual for the rider to require extra pressure to be applied to the pedals of the bicycle to provide greater motive power such as when, for instance, heading into a strong wind or riding up a hill. It is apparent a rider can exert limited pressure only on the pedals without actually being lifted off the seat and this consequently results in the rider having to stand on the pedals to obtain the extra pressure required. By adopting such a stance a rider is able to place more weight or exert more pressure on the pedals than that which would be available when the rider is in a seated position.
It is recognised that standing on the pedals tends to render the bicycle less stable than when the rider is seated and in addition this standing stance will increase wind resistance so that part of the additional effort provided is nullified.
It is therefore en. object of this invention to provide an accessory for use with both existing bicycles and new bicycles which will enable the rider to apply additional pressure to the pedals of the bicycle while remaining seated.
Accordingly, one form of the invention may be said to comprise an accessory for a bicycle consisting of means associated with the seat of the bicycle wherein a first end of a strap can be permanently anchored to the bicycle and the second end of strap can be removably anchored to the bicycle by means which are accessible only when greater than a predetermined minimum weight is applied to the seat.
272839
Preferably the said first end of the strap is anchored to the framework of the bicycle seat at the rear thereof.
Preferably the means for anchoring the second end of the said strap comprise a 5 locking pin which is so constructed that when more than a predetermined weight is applied to the bicycle seat, a portion of the locking pin will protrude through the seat and be accessible to anchor the said second end of the strap.
Preferably the said locking pin is associated with a bar arranged to pivot in a 10 fulcrum by means which sense weight applied to the seat of the bicycle and the pivotal movement of the bar about the fulcrum will move the said locking pin between an operative and a retracted position.
Preferably spring means are provided to spring urge the fulcrum bar to a position 15 whereby the locking pin is moved into a retracted position.
Preferred forms of the invention will now be described with the aid of the accompanying drawings wherein;
Figure 1 is a view of part of the bicycle showing a seat and a seat post which has been adapted to incorporate the present invention.
Figure 2 is a sectional view of a seat of the present invention in a configuration it will occupy when the rider is seated on the seat, and
27283
Figure 3 is a similar view of the seat shown in Figure 2 in a configuration when there is little or no weight on the seat.
As shown in Figure 1, the accessory can be adapted to be attached to a standard 5 bicycle frame 1 of which a portion only is shown in the drawings. A seat post 2 which may be of a standard tubular formation, is partly telescoped within the frame 1 in the normal manner. The upper end of the seat post 2 is attached by a suitable bracket to the underside of a seat 3. The height of the seat 3 above the frame 1 can be adjusted by telescoping the seat post 2 downwards or upwards to the desired degree and then tightening 10 the nut 4 on the clamp 5 in the known manner. The seat includes a shaped covering member 6 of a known kind and may have the usual spring arrangement 7 as known.
The seat mechanism includes a fulcrum bar 8 which can be suitably formed from metal stock or the like and which is supported at a fulcrum point 9 to have a rocking 15 motion about the fulcrum point 9. The fulcrum bar 8 extends under the seat and the forward end 10 terminates adjacent the forward end 6a of the seat. A locking pin 11 is attached to the fulcrum bar 8 adjacent to the forward end 10 of the bar and extends upwardly as shown through a hole 6b formed in the seat cover. The pin 11 is suitably attached to the fulcrum bar 8 so that as the bar rocks about the fulcrum point 9 between 20 the positions shown in Figures 2 and Figure 3 the pin will reciprocate upwardly and downwardly and in the operative position protrude through the seat cover as shown in Figures 1 and 2 and in the retracted position will retract through the hole 6b so the tip of the locking pin 11 will lie below the seat cover.
272839
The rocking motion of the fulcrum bar is controlled by a spring means such as the compression spring 15 which is housed within the seat post 2. Suitable means such as the stop plate 16 is provided to limit the depth of penetration of the spring 15 within the post 2 while the spring 15 is of a length that its upper end will bear against a plate 17 which 5 is of a size that it can have reciprocal movement within the bore of the seat post. Preferably but not necessarily the upper end of the spring 15 will terminate within the seat post 2 as shown in Figures 2 and 3. The plate 17 is formed to contact the foot of an actuating pin 18, the shank of which passes through and is fixed to the fulcrum bar 8 as indicated in the drawings so that the height of the dome 18a of the pin 18 in relation to the 10 fulcrum bar 8 can be adjusted for the purpose to be hereinafter described. The shank of the actuating pin 18 also passes through a hole 6c in the seat cover.
The dome 18a of the pin 18 is affixed to a cover member 20 which is shaped so that it will lie over the outside of the seat covering 6 as indicated particularly in Figure 1. The 15 cover member 20 can be a moulded from a plastics material or it can be formed from a suitable lightweight metal.
A strap support 22 is suitably attached to the seat frame or seat post 2 and is formed so that one end of a strap 23 can be attached to the strap support 22 as shown. The other 20 end of the strap 23 is looped under the cross bar la of the bicycle frame as is shown more particularly in Figure 1. The free end of the strap is then passed over the forward end 6a of the seat and as can be seen for instance in Figure 1, the strap is provided with a series of holes 25 which may be reinforced by suitable eyelets or the like.
272839
The seat depicted in Figure 3 in a configuration where there is no weight or little weight on the seat and in this position the compression spring 15 will have acted to have moved the actuating pin 18 and the cover member 20 upwardly above the seat covering 6 as indicated in the Figure. Because the shank of the actuating pin 18 is attached to the 5 fulcrum bar 8, this movement will rock the fulcrum bar 8 about the fulcrum point 9 so the pin 11 will be retracted through the hole 6b.
*
Figures 1 and 2 depict the configuration when a rider is seated on the seat. In this configuration, the weight of the rider seated on the cover member 20 will compress the 10 spring 15 so the fulcrum bar 8 will rock to move the pin 18 and the cover member 20 downwardly until the mechanism occupies the position as shown in Figures 1 and 2. When in this position, the upper end of the pin 11 will protrude through the hole 6b and an appropriate hole 25 of the strap 23 can be engaged over the protruding end of the pin 11 to lock the strap to the pin.
The adjustment means on the pin 18 will be manipulated so that when the rider is seated and the cover member 20 occupies the configuration shown in Figures 1 and 2, the tip of the pin 11 will project through the seat cover 6 a sufficient amount that a selected eyelet 25 of the strap 23 can be engaged on the pin and be retained thereon. Similarly, the 20 height of the pin 18 in relation to the fulcrum bar 8 is adjusted so that when there is no weight on the seat and under the influence of the spring 15, the cover member 20 adopts the configuration shown in Figure 3, the tip of the pin 11 will have retracted through the hole 6b to a position similar to that shown in the Figure.
272839
In operation the strap will have first been disconnected from around the cross bar la and from the seat 3. When the rider is seated the strap 23 is placed over the shoulder of the rider and the free end of the strap passed under and around the cross bar la and an appropriate hole 25 of the strap is then engaged over the pin 11 which will project through 5 the hole 6b. The strap is adjusted so it will lie comfortably over the rider's shoulder when the rider is for instance in an upright seated position on the seat. If the rider requires to exert additional pressure on the pedals of the bicycle, then the reaction force will be taken by the strap 23 which passes over the rider's shoulder and this will allow the rider to exert considerably more pressure on the pedals while seated than would otherwise be able.
To dismount from the bicycle the rider will disengage the strap from the pin 11 by holding the free end of the strap and lifting the eyelet off the pin. The rider may then dismount in the usual manner. In the event of an accident which results in the rider being •unseated, there will be no weight or little weight on the seat 3. in this situation, the seat 15 mechanism will under the influence of the spring 15 adopt the position shown in Figure 3 so that the pin 11 will be retracted and the free end of the strap 23 will become disengaged and will fall free of the seat.
The foregoing description refers to a preferred form of the invention. Having read 20 and understood the precepts and principles of the invention it will be apparent to those skilled in the particular art to which this invention relates that improvements or modifications can be made to the particular constructional features while still falling within the broad scope of the concept. All such improvements and modifications are intended to be included within the scope of the present invention.
