Abstract

A cable operated calliper brake for use primarily on bicycles in which in use braking force is transferred from the cable 204 to a pair of vertical operating levers 209a and 209b mounted on a centre chassis by means of two sets of horizontal drive levers 201a, 201b, 202a and 202b where each set is pivoted at three points 224-227. The brake is adaptable for centre pull (figures 1 and 2) or side pull action or as a disk brake (not shown). The horizontal levers provide a mechanical advantage.

Description

HIGH EFFICIENCY CALIPER TYPE CYCLE BRAKE
The present invention relates to rim brakes which are intended primarily, but not exclusively, for use on cycles and the like.
The invention consists of an improved calliper type rim brake mechanism which is cable operated and which can be used as a direct replacement for the conventional side pull calliper brake and existing centre pull calliper brakes commonly used on cycles.
There are many different types of cycle rim brakes, the most common consisting of two operating levers pivoting about a common axis. The said operating levers are usually manufactured as pressings and the ends of these levers, to which brake shoes are attached, are cranked into planes at right angles to the plane of the operating levers. This arrangement is to ensure that brake shoes, when attached, are in the correct relationship to the wheel rim.
The said two operating levers are usually fitted with a common return spring to keep the operating levers apart. This type of brake is often known as a side pull calliper because of the fact that the said operating levers are provided with laterally extending portions to which the inner and outer parts of the operating cable are attached respectively. There have been various attempts to improve this arrangement and there are many examples of the basic and improved versions to be found in the art.
In a typical arrangement of the sort described above there is often a tendency for one brake block to be moved outward to a greater extent than the other.
When this happens one block can remain in rubbing contact with the side of the wheel. Also there is little or no mechanical advantage employed in the transfer of braking force from the hand lever via the cable to the calliper action of the operating levers at the end nearest the wheel.
One common attempt to overcome the above disadvantages is to design a centre pull calliper in which the left and right hand operating levers are no longer moved about a common axis but instead are pivoted separately. Each operating lever can be mounted on a common frame and the outer part of the drive cable is then attached to the frame and the inner part of the drive cable is attached to the ends of both operating levers by suitable means. The brake blocks are often mounted in a similar fashion to that of previous examples in that their brake shoe attachment ends are cranked into planes at right angles to the plane of the operating levers This arrangement is an improvement in that it does provide for separate springing for the left and right hand levers which prevents the problem of one brake block remaining in contact with the rim of the wheel when the brake is released. However as with the previously mentioned side pull calliper there is still little or no mechanical advantage employed in the transfer of braking force from the hand lever via the drive cable to the calliper action of the operating levers at the end nearest the wheel.
The present invention provides an alternative design which improves on the disadvantages mentioned above. In a first embodiment a centre pull mechanism is employed to ensure that the positioning of the brake blocks is maintained at all times and two vertical operating levers, are provided which are mounted on a centre chassis and are separately pivoted at each end of the said centre chassis. In use a twin horizontal drive lever system is employed to connect the braking force from the cable to the vertical brake operating levers. These horizontal drive levers are mounted at the opposite end of said vertical operating levers to that end which carries the brake blocks. These horizontal drive levers bring true mechanical advantage and thus reduce the force needed to be applied by a hand lever to move the inner drive cable relative to the outer drive cable and operate the brake. Means are provided for adjustment of the gap between the brake blocks and the wheel rim by providing adjustable brake block mountings which are pivotally attached to the vertical operating levers.
Also there may be means provided so that in use the vertical positioning of the brake blocks may be adjusted.
In a second and preferred embodiment the centre pull action is replaced by a side pull lever system. The principles in previous embodiments are retained and the twin horizontal drive levers are extended on one side of the mechanism only in order to provide an attachment point for the operating cable. Also in this embodiment the twin horizontal drive levers share the same pivot points where they attach to the vertical operating levers.
Additional applications for this mechanism are planned where either the centre pull or the side pull versions are adapted to become the drive mechanism for a disk brake instead of a rim brake. The example given in this specification is the rim application. The word disk may also be spelled disc and in this specification both spellings have the same meaning.
The language of this description refers to horizontal drive levers and vertical operating levers. These are different components. The horizontal drive levers in use consist of two sets of levers, a top set and a bottom set. Each set consists of two parts (also referred to as links) and one end of each of the parts connected together pivotally. Each part is also pivotally connected to one of the vertical operating levers so that the top set of horizontal drive levers has three pivot points as does the bottom set. Because of the centre pivot, the top set of horizontal drive levers usually take up a V shape or an inverted V shape for the bottom set. The vertical operating levers may consist of two parts adjustably connected together. In use there would be an upper part to which the horizontal drive levers are connected and a lower part to which the brake block assemblies are attached, which lower part is also called a brake block mounting arm. The brake blocks themselves are an assembly consisting of the brake block, a block receiving shoe and a means for attaching the assembly to the brake block mounting arm part of one of the vertical operating levers. These components can be clearly seen in the attached drawings.
According to a first feature of the invention there is provided a calliper brake intended primarily but not exclusively for use on bicycles in which in use braking force is transferred from a cable to the vertical operating levers by means of two sets of horizontal drive levers where each set of horizontal drive levers is pivoted at three points.
According to a second feature of the invention there is provided a calliper brake according to the first feature having two sets of horizontal drive levers which have a cable connected at their centre pivot point so as to provide a centre pull action.
According to a third feature of the invention there is provided a calliper brake according to the first feature having two sets of horizontal drive levers in which the said two sets of horizontal drive levers are extended to one side of the brake where an operating cable is attached to the said horizontal drive levers to provide a side pull action.
According to a fourth feature of the invention there is provided a centre pull calliper brake as described in the second feature in which in use each set of the said two sets of horizontal drive levers consist of two links having one end joined to the other link pivotally and the remaining ends joined pivotally to the top of left and right hand operating levers respectively.
According to a fifth feature of the invention there is provided a side pull calliper brake as described in the third feature in which in use each set of the said two sets of horizontal drive levers consist of a short link and a long link which are joined together pivotally at one end and where the other end of the short link is pivotally attached to the one operating lever and the long link joined pivotally at its centre to the other operating lever.
According to a sixth feature of the invention there is provided a calliper brake according to any previous feature in which the said two sets of horizontal drive levers in use are mounted one above the other and each set may or may not share some of their pivot points.
According to a seventh feature of the invention there is provided a calliper brake according to any previous feature with left and right vertical operating levers where each operating lever has a brake block mounting arm which is adjustably mounted upon the upper part of the vertical operating lever.
According to an eighth feature of the invention there is provided a calliper brake according to the seventh feature where the said adjustable mounting consists of the brake block mounting arm being pivotally mounted upon it's respective right or left hand vertical operating lever and a brake block assembly adjustably mounted upon the brake block mounting arm..
According to a ninth feature of the invention there is provided a calliper brake according to the eighth feature where locking means is provided so as to ensure that in use the brake block mounting arm is immovably attached to the operating lever.
According to a tenth feature of the invention there is provided a calliper brake according to any previous feature where a calibration plate is provided which in use may be attached to both the top and bottom sets of horizontal drive levers for the purpose setting their relationship to each other. (The cable may also then be adjusted). After adjustment and when the said calibration plate is removed the horizontal drive levers maintain the same position which they had when the calibration plate was present.
The invention will now be more particularly described by way of example with reference to the accompanying drawings in which, Figure 1, Shows the calliper rim brake in its fully relaxed state when the brake is not applied.
Figure 2, Shows the calliper rim brake with the brake block in contact with the wheel as the brake is applied.
Figure 3 Illustrates the side pull version of the mechanism Referring now to figure 2, this shows the calliper brake positioned for when the brake is applied. The brake consists of left 9a and right 9b vertical operating levers which are pivotally mounted on pivots lOa and lOb on a central mounting plate 11. This central mounting plate is attached to the cycle at point 12.
The operating levers 9a and 9b are connected together at the top by two sets of horizontal drive levers 1 and 2.
Horizontal drive lever set 1 consists of links la and lb. Set 1 of these links are pivotally joined at point 6 and pivotally attached to the operating levers at points 5a and 5b.
Horizontal drive lever set 2 are mounted below set 1 and set 2 consists of links 2a and 2b. The links comprising set 2 are pivotally joined at point 8 and pivotally attached to the operating levers at points 7a and 7b. The set 1 links are similarly connected at their own mounting points.
A cable consisting of outer 3 and inner 4 is connected between set 1 and set 2 of the horizontal drive levers the outer 3 of said cable being connected to set 1, the upper horizontal drive levers and the inner cable 4 passes freely through point 6 and is connected to set 2 the lower horizontal drive levers at point 8 where it is clamped.
This arrangement operates so that when a hand lever (not illustrated) is operated the inner cable moves with respect to the outer cable and this action pulls together the two sets of horizontal drive levers. This extends the length between the centres 5 for the top levers and 7 for the bottom levers and pushes the top of the operating levers away from each other. Because the operating levers are pivoted at points lOa and b the action of pushing the tops of the vertical operating levers away from each other causes the bottom of the vertical levers to come closer together and the brake blocks I 2a and b to come into contact with the wheel riml4.
Brake block assemblies 12 are mounted on brake block mounting arms 15.
These brake block mounting arms 15 are pivotally mounted on the upper vertical operating levers 9 at points 16. They are positioned by screws 18 and when adjusted are locked into place by securing bolts 17.
In order to set up the brake it is important to ensure that the centres of the horizontal operating lever sets 1 and 2 are in the correct position in relation to each other and in order to achieve this, a calibration plate 19 is provided. This plate is removeably attached to points 6 and 8 at the centre of the two sets of horizontal drive levers and then the inner cable, which is slideably attached to point 8 is moved and then locked into position at point 8, then the calibration plate is removed.
Figure 1 is identical to figure 2 except that in this view the brake is not applied.
A gap therefore can be seen between brake blocks 12a and band the rim 14 of wheel 13. Consequently the horizontal operating levers 1 a and b and 2 a and b are opened and shorter so that their centres 6 and 8 are further away from each other than they are shown to be in Figure 2 Figure 3 shows the alternate preferred side pull mechanism. A clarification of language used to describe some parts of the mechanism is first provided.
201a and b Links or parts a and b making the top set of horizontal drive levers 202a and b Links or parts a and b making bottom set of horizontal drive levers 203 Cable outer 204 Cable inner 209a and b Vertical operating levers upper part 212a and b Brake blocks 215a and b Vertical operating levers lower part also known as brake block mounting arms.
220a and b Block receiving shoe 221a Means for attaching the brake block assembly. Note that there are two brake block assemblies, one consisting of parts 212a 220a and 221a and the other of parts 212b 220b and 221b.
The operation of this preferred version is the same as previous versions except that links 201b and 202b are extended and terminated in cable connecting point 222 and sheath connecting point 223. Operation of the cable causes pivot points 224 and 225 to move together which in turn causes pivot points 226 and 227 to move apart which are connected to the vertical operating levers. The vertical operating levers are pivoted at points 228 and 229 therefore this described action causes the brake blocks to move into contact with the wheel.
Adjustment is provided for wear and tear in the brake block assemblies because the brake block mounting arms are pivoted at points 230 and 231, they are moved by the adjusters 234 and 235 and locked in position by lock nuts 232 and 233.
It will be understood that many different embodiments of this invention are possible and that the invention is intended to be limited only by the scope of the claims.
