Description

Device to detect the position of the easel in two-wheelers.

Object of the invention

The present invention patent application Its purpose is to register a device to detect the stand position in two-wheeled vehicles that incorporates notable innovations and advantages over other devices with the same purpose.

More specifically, it refers to a device to detect the position of the easel in vehicles two wheels comprising a body fixed on an axle coupled to the vehicle frame that allows a rotating movement of a rotor arranged inside the body that has a section sectioned as a cam and electrical contact means.

Background of the invention

At present, the use of electrical devices arranged in the area corresponding to the two-wheeled bars of vehicles wheels, such as motorcycles, which allow detecting the stand position to prevent the vehicle from leaving with the easel bar in a position not suitable for driving and that could lead to a dangerous situation for the user, said devices acting as security elements for the driver.

An example of such devices is described in US Patent No. 4,883,284 in the name of Honda in which a switch comprising means of mobile contacts that are concentrically and axially coupled with regarding stationary means of contact. But nevertheless, it presents the main difference of arranging contacts in transverse direction to the easel movement, causing the contact is mobile and sliding so that it causes the contact depends on the parallelism between the fixed contact and the mobile contact once the whole assembly is mounted on the vehicle.

Another disadvantage to highlight is the close proximity between electrically active parts that can cause failure of condensation or contact carbon switching.

On the other hand, a device for the same purpose in European Patent No. EP-A-1 338 497 on behalf of Asahi Dense Co LTD. Said patent describes a device based on the use of a rotor that has a sectioned section that acts as a cam and a button that acts tangentially transmitting a linear movement to the mobile contacts, so that the mobile contact connects and disconnects from the contact fixed by a sliding operation. However, this device and the previous one have the main drawback of that the sliding operation of the contacts implies a greater wear of the linked parts in such operation since the time Connecting and disconnecting the sliding contacts depends on the rotational speed of the rotor where the contact is located mobile, this being a slow transition that generates greater heating and wear of contacts with inductive loads type "relay" drive coils.

Description of the invention

The present invention has been developed with the in order to provide a device that solves the inconveniences previously mentioned, also providing other advantages additional that will be evident from the description that is accompanies next.

The device of the present invention intended to detect the position of the easel in two vehicles wheels comprises a body fixed on an axle coupled to the frame of the vehicle that allows a rotating movement of an arranged rotor inside the body that has a section sectioned by way of cam and contact means to generate an electrical signal from the position, and is characterized by the fact that the inner wall of the central hole of the body includes at least one contact peripheral arranged along a section of the periphery of the said wall and at least one inner contact located in a annular space between the rotor and the inside diameter of at least one peripheral contact, such that in a condition position of the easel a part of the inner contact is in contact with the section sectioned as a cam while another part of said inner contact is in contact with the contact peripheral, said inner contact being movable in a angular movement with respect to the rotor.

Unlike the mentioned devices previously in the state of the art, rotational movement of the rotor is transformed into an angular movement of one end of the internal contact as well as the fact that the contacts do not They are arranged concentrically. In addition, another aspect differentiator is the fact that the relative position of the contacts, from the mechanical and non-electrical point of view, in the devices of the known technique is stationary with each other with a slippage, that is, there is always a physical union between contacts while in the present invention said position relative is dynamic without slip, basically with a movement of a degree of freedom.

Thanks to these characteristics, you get a device that basically improves the passage of electric current between contacts and, on the other hand, increases the lifespan of some interior elements by reducing friction wear since in  the cases mentioned in the background, the electrical contacts establish contact with each other by sliding to make the connection and disconnection of the device. For him on the contrary, the device of the invention makes the contact electric without sliding by rapid approach and decrease in physical distance between contacts until a direct contact, producing only mechanical sliding between the inner contact and the rotor.

According to another aspect of the invention, the device is provided with two peripheral contacts facing each other covering most of the circumference length of The inner wall of the body.

Advantageously, the inner contact is constituted by a single flexible body that has two sections symmetrical facing each other and whose central part is set.

According to another embodiment of the invention, the inner contact may consist of two flexible bodies independent and the rotor can have two cam bodies that are overlapped and offset by an angle to its axis, of so that they activate two or more independent internal contacts overlaid at different heights.

Other features and advantages of the device object of the present invention will be apparent from the description of a preferred, but not exclusive, embodiment illustrates by way of non-limiting example in the drawings that are accompany, in which:
