Abstract

An adaptor 1 for attaching a cleat 30 to a bicycle shoe 10 includes an engaging portion (11, Fig. 2) and a base part 12. The engaging portion is formed on and protrudes from the first side of the base part and is adapted to be connected to the underside of the bicycle shoe. A recess 13 is defined in the second side of the base part and includes two first holes 131 that are defined through its inner bottom and through the engaging portion. Two locking members 2 extend through the first two holes and are connected to the bicycle shoe. A second side of the base part is adapted to be removably connected to the cleat. The second side may be curved and may include three second holes 123 for attaching the cleat. The bottom of the base part (122, Fig. 2) may include multiple cavities and ribs (124, 125, Fig. 2), and a ring (126, Fig. 2) that encloses the engaging portion. The engaging portion may comprise multiple bosses (14, Fig. 2). The shoes may be used as mountain bike shoes with the cleat attached and as road bike shoes by removing the cleat.

Description

ADAPTOR FOR BICYCLE SHOES BACKGROUND OF THE INVENTION

1. Fields of the invention

The present invention relates to a bicycle shoe and, more 5 particularly, to an adaptor for a bicycle shoe so that a cleat is removably connected to the adaptor.

2. Descriptions of Related Art

There are two main catalogues for bicycles, and which are road bikes and mountain bikes. The shoes for being used with the pedals of the two different types of bicycles are also divided into two different types. For mountain bikes, the shoes are equipped with a specifically designed cleat attached to the underside of the shoe so as to be engaged with the pedals of the mountain bikes. For the road bikes, the shoes have a flat underside. Therefore, two types of shoes are required if the users want to use both the road bikes and the mountain bikes. However, the bike shoes are costly, and thc users have to prepare the two different types so as to enjoy the pedaling of the two different types of bikes. It is inconvenient for the user to carry the two different shoes as well.

The present invention intends to provide an adaptor for a bicycle 70 shoe. A cleat for mountain bikes can be removably connected to the adaptor to switch the shoe from a road bike shoe to a mountain bike shoe.

SUMMARY OF THE INVENTION

The present invention relates to an adaptor for a bicycle shoe, and includes an engaging portion and a base part. The engaging portion is formed on the first side of the base part, and protrudes from the first side of 5 the base part so as to be connected to the underside of the bicycle shoe. A recess is defined in the second side of the base part and includes two first holes defined through its inner bottom. The two first holes are defined through the engaging portion. Two locking members extend through the two first holes and are connected to the bicycle shoe. A cleat is removably 10 connected to the second side of the base part. The bicycle shoes with the cleat arc used as mountain bike shoes, and used as road bike shoes by removing the cleats.

The user only needs to prepare the bicycle shoes, by using the adaptor of the present invention, when riding a mountain bike, the user wears the bicycle shoes with the cleat. When riding a road bike, the cleat is removed from the engaging portion of the adaptor of the present invention, The user does not need to change the bicycle shoes and is able to ride mountain bikes and road bikes.

The present invention will become more obvious from the 20 following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

BRIEF DESCRIPTION OF THE DRAWINGS

Fig. 1 is a perspective view to show the adaptor of the present invention; Fig. 2 is another perspective view to show the adaptor of the present invention; Fig. 3 shows that the adaptor of the present invention is attached to the bicycle shoe, and a cleat is connected to the adapter; Fig. 4 is an exploded view to show the adaptor of the present invention, the bicycle shoe and the cleat as shown in Fig. 3; Fig. 5 is another exploded view to show the adaptor of the present invention, the bicycle shoe and the cleat as shown in Fig. 3, and Fig. 6 is a cross sectional view, taken along line VI-VI in Fig. 3, 15 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to Figs. 1 to 5, the adaptor 1 for a bicycle shoe 10 of the present invention comprises an engaging portion 11 and a base part 12. The engaging portion 11 is formed on the first side of the base part 12, and protrudes from the first side of the base part 12 so as to be connected to the 20 underside of a bicycle shoe 10. An elongate recess 13 is defined in the second side of the base part 12, and two first holes 131 are defined through the inner bottom of the recess 13. The two first holes 131 are also defined through the engaging portion 11. Two locking members 2 extend through the two first holes 131 and are connected to the bicycle shoe 10. A cleat 30 is removably connected to the second side of the base part 12, wherein the second side of the base part 12 is opposite to the first side of the base part 12.

The first side of the base part 12 includes a bottom 122 to which the engaging portion 11 is formed. The second side of the base part 12 is a curved face 121 that is designed to meet ergonomic requirements. The second side of the base part 12 is to be connected to the cleat 30, The curved face 121 includes at least three second holes 123 such that three bolts 301 extend through the cleat 30 and are connected to the at least three second holes 123 so as to match the cleat 30 to the curved face 121 of the base part 12.

The bottom 122 of the base part 12 includes multiple cavities 124 and multiple ribs 125 which divide the cavities 124. A ring 126 is formed to the bottom 122 of the base part 12. The engaging portion 11 is enclosed by the ring 126 which is formed with the ribs 125. The ribs 125 and the ring 126 are designed to reinforce the structure of the base part 12. Each cavity 124 includes an inner bottom which is not a flat inner bottom and is composed of multiple inclined surfaces. As shown in Figs. 4 and 5, there are multiple protrusions 101 protruding from the underside of the bicycle shoe 10 to provide anti-slip function. In addition, when the base part 12 is connected to the underside of the bicycle shoe 10, some of the protrusions 101 are inserted into the cavities 124 so that the protrusions 101 do not affect installation of the base part 12 so that the base part 12 is attached to and matched to the underside of the bicycle shoe 10.

Furthermore, the engaging portion 11 includes multiple bosses 14 protruding from the end face thereof as shown in Fig. 2. The bosses 14 contact the underside of the bicycle shoe 10 so as to generate friction, so that the adaptor 1 does not shift when being connected to the underside of the bicycle shoe 10.

In order to avoid the locking members 2 from hitting the base part 12, a plate 3 is located in the recess 13 and includes two bores 31. The two locking members 2 extend through the two bores 31 and the two first holes 131 so as to be connected to the bicycle shoe 10. The two locking members 2 do not protrude beyond the recess 13. The locking members 2 are hidden in the recess 13 by the cleat 30. By the plate 3, the heads of the locking members 2 do not contact the base part 12 to cause worn between the locking members 2 and the base part 12. The base part 12 is integral with the engaging portion 11 to be a one-piece part which can be made of aluminum alloy to reduce weight.

The users do not prepare two different types of bicycle shoes. The adaptor 1 is easily connected to the bicycle shoe 10 by the two locking members 2. The cleat 30 is easily connected to the base part 1 by extending the bolts 301 through the cleat 30 and are connected to the second holes 123.

That is to say, any user can easily connect the cleat 30 to the adaptor 12, or remove the cleat 30 from the adaptor 12.

While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the 10 scope of the present invention.
