DETAILED DESCRIPTION OF THE FIGURES

(18) Turning to FIGS. 1, 4, 5 and 8, a bicycle pedal adapter 10 according to the invention is shown. The bicycle pedal adapter is configured to be clicked onto a bicycle pedal 100 which is intended and constructed to be used for a bicycle shoe having a cleat. The bicycle pedal adapter is configured to convert the bicycle pedal to a bicycle pedal suitable to be used with a normal shoe without a cleat.

(19) The bicycle pedal adapter comprises a main body 18 having a height 12, a width 14 and a length 16. The main body is flat. The width 14 is more than four times the height 12 and the length 16 is more than five times the height. The height 12 is generally less than 15 mm, in particular less than 13 mm. The main body 18 has a front end 20 and a rear end 30. The front end has a front coupling 22 configured to mate with a front clamping member 102 of the bicycle pedal. The rear end has a rear coupling 32 configured to mate with a rear clamping member 104 of the bicycle pedal.

(20) The bicycle pedal adapter is configured to be clicked onto the bicycle pedal by hand 150 and to be uncoupled from the bicycle pedal by hand or with a tool 90. The bicycle pedal adapter has a foot support surface 28 which faces upwards. The main body does not comprise a plurality of coupling holes 210, 310 via which the bicycle pedal adapter can be connected to a bicycle shoe via a connecting member, as shown in the prior art FIGS. 14 and 15.

(21) At least one hole or recess 60 is provided in the bicycle pedal adapter. The at least one hole or recess is configured to be engaged by a decoupling tool 90. The at least one hole or recess is provided in a side 66, 68 and extends in particular from one side 66 to the opposite side 68. For decoupling reasons, the hole or recess is positioned in a rear part of the main body. Said position creates the desired arm for decoupling the bicycle pedal adapter with the use of the decoupling tool 90.

(22) The rear coupling 32 has stopping sections 26. The stopping sections are integrally connected to the main body and are triangular shaped sections, with a rounded corner. When viewed in top view, the stopping sections 26 extend at an angle with a lateral plane 27.

(23) The angle lies between 10 and 45 degrees, more in particular between 20 and 30 degrees.

(24) The front coupling 22 has a first protrusion 24 which extends in a downward and forward direction from the main body of the bicycle pedal adapter.

(25) The first protrusion 24 has a shape of a part of a circle, in particular a semi-circular shape when viewed in bottom view. This is shown in FIG. 2.

(26) The first protrusion 24 has an upwardly facing support surface 140 and a forwardly facing support surface 141. The upwardly facing support surface 140 and the forwardly facing support surface 141 meet along a pivot line 54 which defines a front pivot axis 56. During coupling and decoupling, the bicycle adapter pivots around the front pivot axis.

(27) The bicycle pedal adapter has a vertical left side 66 and vertical right side 64.

(28) Turning to FIGS. 5 and 7, the rear coupling 32 comprises a second protrusion 34. When seen in top view, the second protrusion 34 is located between the stopping sections 26. In top view the second protrusion extends rearward from the main body of the bicycle pedal adapter. In top view, the second protrusion has a width which is smaller than 40 percent of a width of the main body.

(29) The second protrusion is provided at a lower half of the bicycle pedal adapter when seen in rear view. A protrusion height 36 of the second protrusion is less than half of the height 12 of the bicycle pedal adapter. The second protrusion is configured to mate with the rear clamping member 104.

(30) An upper side of the second protrusion comprises an engagement surface 38 which faces upwards. In use, the rear clamping member engages the engagement surface 38, thereby maintaining the position of the bicycle pedal adapter.

(31) When viewed in top view the second protrusion has a curved shape, wherein an apex of the curve is located on a vertical longitudinal midplane 19 of the bicycle pedal adapter.

(32) The stopping sections 26 and second protrusion 34 together form a substantially W-shaped rear end, when seen in top and/or bottom view.

(33) The rear coupling 32 has a guiding surface 40 at a lower section of the second protrusion when viewed in cross-sectional side view taken along the longitudinal midplane 19.

(34) The shown embodiments of the bicycle pedal adapter are all single integral bodies. A single integral body provides a robust construction. Keeping in mind an easy way of manufacturing, the bicycle pedal adapter may be made from a single material. Plastic, aluminium or titanium could be chosen as single material for their positive material properties. The stiffness and strength to mass ratios of these materials are suited for a product such as the bicycle pedal adapter. The bicycle pedal adapter can be manufactured with injection moulding.

(35) The foot support surface 28 can be provided with a textured surface. The textured surface prevents slipping between the user's shoe and the bicycle pedal adapter. Another option would be to provide anti-slip material on the foot support surface.

(36) The single material has a density of less than 4 g/cm3. This density leads to a total weight of less than 50 gram, in particular less than 40 gram, more in particular less than 30 gram for the bicycle pedal adapter. In case of hard plastic, the density may be lower than 2 g/cm3.

(37) When viewed in top view the bicycle pedal adapter is substantially symmetric about the vertical longitudinal midplane 19. A symmetric product is convenient for the user, because the user does not have to worry about matching the correct adapter with the corresponding pedal (left or right). A set of bicycle pedal adapters are identically shaped.

(38) Turning to FIGS. 9 and 10, in side view the main body 18 has a substantially flat foot support surface 28. In the same view the main body 18 also has a substantially flat bottom side 42. The foot support surface furthermore follows a straight line. In side view, the main body 18 increases in height from the front end to the rear end. The foot support surface 28 and the flat bottom side 42 are oriented at an angle of about 4-10 degrees with respect to one another.

(39) The bicycle pedal adapter is configured to be decoupled by firstly pivoting the bicycle pedal adapter around a pivot axis 52 which extends perpendicular to the foot support surface and by subsequently lifting the bicycle pedal adapter from the pedal.

(40) Turning to FIGS. 3, 4 and 11, an assembly according to the invention is shown of the bicycle pedal adapter and a crank 130 with a bicycle pedal 100 having a cleat coupling. The cleat coupling comprises a front clamping member 102 which mates with the front coupling 22. The cleat coupling further has a rear clamping member 104 which mates with the rear coupling 32 and a central support section 106 on which a main body 18 of the bicycle pedal adapter rests.

(41) The pedal is free to rotate relative to the crank 130. In side view the pedal and bicycle pedal adapter together rotate to a stable orientation under the influence of gravity. In the stable orientation in side view the foot support surface 28 defines an angle of 0-60 degrees relative to a vertical axis 126, more in particular 25-45 degrees.

(42) The main body extends between a front section 108 and a rear section 110 of the bicycle pedal.

(43) A foot support surface 28 of the main body is substantially flush with the bicycle pedal, more in particular substantially flush with an upper part of the front clamping member 102 and an upper part of the rear clamping member 104. Flush in this context does not mean that the upper surface needs to be exactly flush. The upper surface 28 may be raised to a maximum distance of 5 mm above a plane 118 defined by the upper parts of the front and rear clamping members.

(44) Both front and rear couplings are constructed to prevent undesired movements of the bicycle pedal adapter during cycling. This dimension of the front coupling prevents lateral movements of the bicycle pedal adapter. The stopping sections 26 also prevents the bicycle pedal adapter from making unintended lateral movements, as well as any pivoting movements about an axis 52 which extends at right angles to the upper surface. The clamping members prevent movements away from the plane defined by the central support section.

(45) The bicycle pedal adapter comprises a guiding surface 40 between the rear end 30 and a bottom side 42 of the main body. In side view the guiding surface is curved and configured to guide the bicycle pedal adapter smoothly over an edge 120 of the rear clamping member of the bicycle pedal. The guiding surface 40 is configured to smoothly bias the rear clamping member in a rearward direction 124 when the bicycle pedal adapter is clicked onto the pedal.

(46) The second protrusion 34 as shown in FIG. 5 is configured to mate with the rear clamping member 104. An upper side of the second protrusion comprises an engagement surface 38 configured to be engaged by the rear clamping member and to be positioned underneath the rear clamping member. The rear clamping member keeps the bicycle pedal adapter in place and prevents the bicycle pedal adapter from detaching from the central support section.

(47) The foot support surface of the bicycle pedal adapter has a width 14 at its widest portion which is equal to the width 122 of the bicycle pedal or is larger than the width of the bicycle pedal. In the shown embodiment, the foot support surface extends outwardly over a distance of 0-5 mm to the left and to the right beyond the bicycle pedal, This is shown in respective FIGS. 8 and 13.

(48) In the present invention it was recognized that the rear clamping member can be accessed by hand and therefore be utilized for the removal of the bicycle pedal adapter. The shoe attached to a cleat adapter prevents access to the rear clamping member. It can therefore only be removed by pivoting the shoe.

(49) Clicking the bicycle pedal adapter 10 onto a bicycle pedal 100 having a cleat coupling can be carried out as follows: a) inserting the front coupling 22 of the bicycle pedal adapter under a front clamping member 102 of the cleat coupling, b) pivoting the rear clamping member 104 of the bicycle pedal 100 rearward, thereby creating space for the second protrusion 34, c) engaging a bottom side 62 of the bicycle pedal adapter with an upward facing contact surface 128 of a central support section 106 of the pedal, wherein the second protrusion 34 of the rear coupling of the bicycle pedal adapter is inserted underneath the rear clamping member of the bicycle pedal, d) pivoting the rear clamping member of the bicycle pedal back to its initial position thereby fixing the bicycle pedal adapter to the pedal.

(50) Of the abovementioned steps, step b) can comprise pushing a guiding surface 40 against an edge 120 of the rear clamping member, causing the rear clamping member to move rearward. Step b) can also comprise manually pivoting the rear clamping member rearward and thereby creating the required space for the second protrusion to move past the rear clamping member.

(51) Turning to FIGS. 10, 11 and 13, different decoupling methods are shown. The bicycle pedal adapter can be decoupled by manually pivoting the rear clamping member, thereby providing the required space for the bicycle pedal adapter to be pivoted about a front pivot axis 56. This is particularly shown in FIG. 11.

(52) A method for decoupling the bicycle pedal adapter comprises reversing the abovementioned steps. First the rear clamping member is moved rearward. This movement is done by manually pulling the rear clamping member rearward. When the rear clamping member does no longer engage the engagement surface 38 of the second protrusion, the bicycle pedal adapter can be pivoted about the front pivot axis 56 in the second direction 94.

(53) FIG. 10 shows a decoupling method wherein the bicycle pedal adapter comprises a hole or recess 60 in which a decoupling tool 90 can be inserted for decoupling the bicycle pedal adapter from the bicycle pedal. This method comprises the following steps: a) inserting a decoupling tool 90 in a hole or recess of the bicycle pedal adapter, b) pivoting the bicycle pedal adapter about a perpendicular pivot axis 52 by pulling the decoupling tool in a first direction 92, c) engaging the rear clamping member with a stopping section 26, thereby pivoting the rear clamping member backwards, providing space for the rear coupling to move upward, d) pulling the decoupling tool in a second direction 94, as shown in FIG. 11, wherein the second direction is substantially perpendicular to a central support section 106 of the bicycle pedal, thereby removing the bicycle pedal adapter from the pedal.

(54) Turning to FIGS. 11 and 13, another method for decoupling the bicycle pedal adapter is shown, comprising the steps: a) engaging a side 64 of a rear part of the main body of the bicycle pedal adapter with a hand 150 of a user, b) pivoting the bicycle pedal adapter, in particular about a pivot axis 52 which extends perpendicular to the foot support surface, by manually pushing on the outer side, thereby engaging the rear clamping member with one of the stopping sections, and pivoting the rear clamping member to the rear by pushing the stopping section against it, c) lifting the rear end up with another hand of the user, thereby pivoting the bicycle pedal adapter about a front pivot axis 56, d) removing the bicycle pedal adapter from the bicycle pedal.

(55) Turning to the prior art FIGS. 14 and 15, a Look cleat 200 and a Shimano cleat 300 are shown. Both cleats have a front coupling 201, 301 and a rear coupling 202, 302. Both rear couplings 202, 302 have a protrusion having an upwardly facing engagement surface 204, 304. These engagement surfaces 204, 304 are constructed to be engaged by the rear clamping member 104 of the bicycle pedal. Compared to the invention, the engagement surfaces of the protrusions of the prior art are wider. Due to the wider engagement surfaces, the rear clamping member remains engaged for a larger pivot angle of the cleat. The larger pivot angle for decoupling of the cleat requires more strength. The present invention has constructed the engagement surface such that the desired pivot angle for decoupling is smaller compared to the existing cleats. In the end this leads to the easier decoupling of the bicycle pedal adapter from the bicycle pedal.

(56) The coupling holes 210, 310 are used to connect the cleat to a bicycle shoe via screws. The position on the bicycle shoe where the cleat is connected has a convex surface. Therefore the cleats have a concave contact surface 220, 320. The present invention has a flat support surface 28, which is better suited for regular shoes with stiff soles.

(57) In most of the cleats according to the prior art a certain pivotal play of the cleat adapter is possible during use for physical reasons. If a cyclist cannot easily twist his foot during cycling, it can for example cause knee injuries. In the present invention it was recognized that for the use of a shoeless cleat adapter a freedom of movement during use is in fact undesired. It has a negative effect on the control of the feet on the pedals. Therefore a cleat adapter is desired that is substantially immovable after being clicked onto a bicycle pedal. However, the user still has to be able to remove the bicycle pedal adapter. The present invention provides a solution to this problem, as described above.

(58) As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention, which can be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriately detailed structure. Further, the terms and phrases used herein are not intended to be limiting, but rather, to provide an understandable description of the invention.

(59) The terms a or an, as used herein, are defined as one or more than one. The term another, as used herein, is defined as at least a second or more. The terms including and/or having, as used herein, are defined as comprising (i.e., open language, not excluding other elements or steps). Any reference signs in the claims should not be construed as limiting the scope of the claims or the invention.

(60) The mere fact that certain measures are recited in mutually different dependent claims does not indicate that a combination of these measures cannot be used to advantage.
