ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention generally relates to a cable operated display device for a bicycle. More specifically, the present invention relates to the attachment of a cable to a display device for a bicycle.
2. Background Information
Bicycling is becoming an increasingly popular form of recreation as well as a means of transportation. Moreover, bicycling has become a very popular competitive sport. Whether the bicycle is used for recreation, transportation or competition, the bicycle industry is constantly improving their components. In particular, bicycle components are constantly becoming lighter and less expensive while maintaining a high level of performance. Moreover, bicycle components are constantly being designed so as to be more ergonomic and user friendly. One particular component of the bicycle that has been extensively redesigned over the past years, are the shifting units of bicycles.
There are many types of shifting units that are currently available on the market. The shifting units range in quality and price. Regardless of the quality and price of the shifting unit, the shifting unit typically will have some sort of display device or gear position indicator. The shifting units are normally located at the ends of the handlebar such that the rider can easily perform a shifting operation without significantly changing the position of the rider's hand. Typically, the gear position indicator or display device is located at the take-up member of the shift operating device that winds up the inner wire of the shift control cable. However, this positioning of the gear position indicator or display device makes it difficult to determine the current gear position. In other words, the rider must look towards the handle portion of the handlebars in order to determine the current gear positions. Accordingly, this is very inconvenient for the rider. Examples of such shifting devices are disclosed in U.S. Pat. Nos. 5,052,241 to Nagano and 5,458,018 to Kawakame.
Accordingly, gear indicators have been developed which are mounted on a center portion of the bicycle so that the rider does not have to take his or her eyes off of the road to determine the current gear position. Examples of gear indicators or displays that are mounted on a center portion of the bicycle are disclosed in U.S. Pat. Nos. 3,524,979 to Cohen and 5,178,033 to Kund. Another example of an indicator that is mounted on a center portion of the bicycle is disclosed in Japanese Utility Model Publication No. 60-23273 which discloses a shifter mounted on the upper horizontal frame tube and in which the indicator is mounted on a center portion of the handlebars. However, these types of gear indicators are often difficult to install and are complicated and expensive.
Another example of a gear indicator that is mounted on the center section of a handlebar is disclosed in European Patent Publication No. 0 629 860 to Shimano Inc. This patent discloses a display panel that is mounted on the center section of the handlebars. While this gear indicator device is very good, it is expensive. Moreover, this indicator can be difficult to install in certain circumstances. Specifically, since both of the shift operating devices are coupled to a single indicator housing, this can make it difficult for the installer. In particular, the installer must first install each of the shift operating devices and then install the indicator on the handlebars. Since there are two cables connected to the gear indicator, it may be difficult to position at the most desirable position.
In view of the above, there exists a need for a mounting device that is adjustable to support the orientation of the bicycle component and that overcomes the above mentioned problems in the prior art. This invention addresses this need in the prior art as well as other needs, which will become apparent to those skilled in the art from this disclosure.
SUMMARY OF THE INVENTION
One object of the present invention is to provide a display device that is easy to attach the indicator cable thereto.
Another object of the present invention is to provide a display device, which is lightweight in design.
Another object of the present invention is to provide a display device, which can be relatively easy to manufacture by conventional manufacturing techniques.
Yet still another object of the present invention is to provide a display device, which is relatively inexpensive to manufacture.
The above objects can also be fulfilled, according to the present invention, by providing a mounting device adapted to be coupled to a portion of a bicycle to support at least one bicycle component thereon. A cable operated display device for a bicycle is provided in which the cable can be easily installed or replaced. The cable operated display device includes a mounting portion, a housing, an internal take-up element and a lid. The mounting portion is adapted to be coupled to a portion of a bicycle. The housing is coupled to the mounting portion. The housing has an interior cavity and an open front. The internal take-up element is pivotally coupled within the housing about a first pivot axis. The internal take-up element has a cable attachment portion that is accessible through the open front of the housing without detaching the internal take-up element from the housing. The lid is releasably coupled to the housing to overlie the open front of the housing. The lid has a window to view the movement of an indicator coupled to the internal take-up element.
These and other objects, features, aspects and advantages of the present invention will become apparent to those skilled in the art from the following detailed description, which, taken in conjunction with the annexed drawings, discloses preferred embodiments of the present invention.
