Abstract

A wrench 11 for unscrewing a shoe cleat (1, Fig.1) from a receptacle (2, Fig.1) in a shoe sole (3, Fig.1) has a member 12 rotatable about an axis 14. The member 12 has a cleat-engaging surface 15 with projections 16, each projection 16 having a radial extent and a cutting edge 17 defined at the conjunction of first and second surfaces 19, 20. The angles A,B between the surfaces 19, 20 and a plane 22 perpendicular to the axis 14 are arranged so that the cutting edge 17 bites into the cleat when an unscrewing torque is applied. The wrench 11 ensures that the cleat 1 can be removed even when it is worn and screwed in very tightly.

Description

2355681 WRENCH This invention relates to wrenches for removing shoe cleats
from receptacles in the soles of sports shoes.
Normally, a removable shoe cleat comprises a body having a member adapted for screw-threaded engagement with the receptacle, and a groundengaging member projecting from the body. Most known cleats have in the body two circular recesses in which corresponding pin projections on a wrench are adapted to engage, so that the cleat is inserted and removed by applying torque using the wrench.
Traditional cleats have a single ground-engaging member and are made of metal and/or a hard plastics material. The recesses are not affected by wear of the cleat, so that insertion and removal of the cleat is relatively easy. Recently, golf shoe cleats in particular have been made of softer plastics material, and have several smaller ground-engaging members. Recesses are still provided for insertion and removal. However, such cleats wear more quickly, and sometimes the body round the recesses wears, so that the depth of the recesses is reduced. Further, the recesses tend to fill with dirt more easily on this type of cleat. As a result, it can be extremely difficult to insert the projections of the wrench far enough to apply an adequate removal torque to the cleat. Sometimes a large axial force has to be applied to keep the projections on the wrench in engagement with the recesses of the cleat. Furthermore, because the material of the cleat is relatively soft, the torque applied by the wrench can distort the cleat material before unscrewing the cleat. In extreme cases, if the cleat is screwed in very tightly, and/or if the are reduced in depth due to debris or wear, the projections can destroy the recesses altogether.
2 According to the present invention a wrench for unscrewing a shoe cleat from a receptacle has a member rotatable about an axis and having a cleatengaging surface with at least two projections, each projection having a radial extent and a cutting edge defined at the conjunction of first and second surfaces, the first and second surfaces being so constructed and arranged that at any point on the cutting edge the angle between the first surface and a plane perpendicular to the axis is greater than or equal to 90' and the angle between the second surface and the plane is less than 90', the first surface being the leading surface in the unscrewing direction.
Instead of projections engaging in recesses the wrench has cutting edges adapted to bite into the cleat body to provide the necessary engagement.
In fact, the arrangement of the cutting edges means that as the torque applied to the wrench increases, the cutting edges bite deeper to increase the engagement with the cleat, so that an adequate removal torque can be applied. Further, it is not necessary to apply a large axial force to the wrench to keep it in engagement with the cleat, as the cutting edges effectively convert part of the torque into axial movement. As a result, the cleat will be relatively easy to remove, whatever its state of wear.
Preferably the cleat-engaging surface has four projections, but it may have any desired number. Each projection preferably extends radially.
Alternatively, the projections may be curved or angled, as long as they have a radial extent. The height of each projection may reduce towards the axis of the wrench, in order to fit the surface of the typical cleat body. However, the projections may have any desired profile, to suit any particular cleat body.
3 Conveniently each cutting edge is straight, and extends radially. Alternatively each cutting edge may be curved or angled, as long as it has a radial extent. The angles between the first and second surfaces and the plane may vary along the length of the cutting edge.
The wrench member may be permanently attached to a handle so that it forms a self-contained tool.
Alternatively, the member may be adapted to be removably mounted in a handle. It can then be included in a kit with other tools which also fit the handle. Preferably, the surface of the wrench member opposite to the cleat-engaging surface has locating means for engagement with the handle. The locating means may include an axially-extending pin. The removable wrench member may be reversible, with the opposite surface including the traditional projections adapted to engage in recesses in the cleat, for insertion of the cleat.
In either embodiment (removable or fixed) a cover may be provided for the cleat-engaging surface to provide protection for the cutting edges.
The cover may then include the projections used in insertion of the cleat.
The wrench member may be made of aluminium, stainless steel or a hard plastics material.
An embodiment of the wrench according to the invention is illustrated by way of example in the accompanying drawings in which:
Figure I is a part-section through a shoe cleat in a receptacle in a shoe sole, and showing a traditional cleat wrench; 4 Figure 2 is a side view of the wrench member of the invention fitted in a handle; Figure 3 is a top view of the wrench member of Figure 2; 5 Figure 4 is a section through the wrench member of Figure 2; and Figure 5 is an enlarged detail of the wrench member of Figure 2.
Figure I shows diagrammatically a known golf shoe cleat 1 held in a receptacle 2 in a shoe sole 3. The cleat I has a body 4, from one side of which a screw-threaded spigot 5 projects for engagement in a complementary screw-threaded socket 6 in the receptacle 2. The other side of the cleat body 4 has several ground-engaging members 7, and a pair of diametrically opposed circular recesses 8, in which pin projections 9 on a standard wrench 10 are engaged for manual insertion and removal of the cleat I by rotation of the wrench 10. Where the cleat 1 is of soft plastics material, the body 4 can wear to such an extent that even the part round the recesses 8 wears, reducing the depth of the recesses 8. The standard wrench 10 may then be difficult to use, as a large axial force must be applied to keep the projections 9 in the recesses 8 while the unscrewing torque is applied. In extreme cases, the projections 9 can actually render the recesses 8 useless, especially if the recesses are reduced in depth.
The wrench 11 according to the invention, and shown in Figures 2 to 5, is adapted to remove the cleat 1 even when it is worn. The wrench 11 of Figure 2 has an aluminiurn wrench member 12 mounted in a handle 13 for rotation about an axis 14. The member 12 has a cleat-engaging surface 15 with four projections 16. Each projection 16 has a radial extent and a cutting edge 17 designed to bite into the cleat body 4 (and not the recesses 8) as an unscrewing torque is applied, thus reducing the axial force that needs to be applied to keep the wrench member 12 in engagement with the cleat body 4.
As can be seen in Figures 2 to 5, the cleat-engaging surface 15 is circular, with the projections 16 extending radially from the circumference 18 towards the axis 14. Each projection 16 has a trapezoidal section defined by surfaces 19, 20, 21 (see Figure 5) and reduces in height from the circumference towards the axis 14, to match the surface of the cleat body 4. Each cutting edge 17 is defined between surfaces 19 and 20.
Figure 5 shows the angles of the surfaces 19 and 20 in relation to a plane 22 perpendicular to the axis 14. The surface 21 extends axially from the surface 20 to the cleat engaging surface 15. The angle A between the surface 19 and the plane 22 is greater than or equal to 90' (in the embodiment shown approximately 1009 while the angle B between the surface 20 and the plane 22 is less than 90' (as shown approximately 40').
The angle C between the surfaces 19 and 20 is also less than 90' (as shown approximately 40'). The surface 19 is the leading surface in the unscrewing direction. As a result of the arrangement of the surfaces 19, 20, the cutting edge 17 bites into the cleat body 4 when the unscrewing torque is applied.
The wrench member 12 of Figure 2 is removably mounted in the handle 13, and has locating means 23 on its side 24 opposite the cleat engaging surface 15. The locating means 23 are adapted to fit the particular handle, and ensure that there is no relative rotation between the handle 13 and the wrench member 12. As shown best in Figure 4, the locating means 23 comprise peripheral castellations 25 adapted to fit into 6 corresponding castellations 26 on the handle 13, and an axially extending pin 27 which is a press fit in an axial bore 28 in the wrench member 12.
The principal use of the wrench member 12 is to remove a shoe cleat 1 from the receptacle 2, whatever its state of wear. With the wrench member 12 located on the handle 13, the surface 15 is engaged with the cleat body 4. It is not necessary to try to locate any of the projections 16 in the recesses 8; instead the projections 16 simply rest on the cleat surface. An unscrewing torque is applied to the wrench member 12 by manual operation of the handle 13. As the torque is applied the cutting edges 17 of the projections 16 bite into the cleat body 4, and increase the axial engagement between the body 4 and the wrench member 12. It will not be necessary to apply a large axial force manually to keep the wrench member 12 in engagement with the cleat body 4 because the projections 16 effectively convert part of the torque into an axial force. Eventually the torque will act to unscrew the cleat 1 from the receptacle 2. The wrench member 12 will operate successfully even if the recesses 8 are reduced in depth or filled with dirt, and its action ensures that the torque applied acts on the screw-threaded engagement, rather than distorting the soft material of the cleat body 4.
After use, the wrench member 12 can readily be removed from the handle 13.
In a modification (not shown) the wrench member 12 may be permanently fixed to a handle, to form a separate tool.
As shown, the projections 16 extend only radially, as do the cutting edges 17. It will be appreciated that either the projections 16 or the cutting edges 17 could be curved or angled, as long as they have a radial 7 extent. Similarly, the profile of the projections 16 may be altered to suit any particular cleat body 4.
It will also be appreciated that the angles A, B and C may be varied 5 within the limits set out above.
In a further modification (not shown) the side 24 of the wrench member 12 may include the standard wrench pin projections 9, the wrench member 12 being adapted to be reversibly mounted on the handle 13 to 10 allow the projections 9 to be used for inserting the cleat.
In yet another modification (not shown) a cover may be provided for the wrench member 12. The cover would fit over the cleat-engaging surface 15 to protect the cutting edges 17. The cover may include on its outer surface pin projections 9, enabling it to be used for inserting cleats.
Although the wrench member 12 is described as being of aluminium, it could be made of any other suitable material, for example hard plastics material, or stainless steel.
