Abstract

There is a need to control more functions with a joystick, e.g. on a forestry harvester or forwarder. Room for additional switches and sensors is very limited on the handle. More or less extra buttons which are added to user side of the surface has poor ergonomic. This invention solves the problem by placing extra switches and sensors to the hidden positions under the main movement structure. This is a very cost effective solution and feasible with the same kind of technology which already is widely used for the movement and position sensors. There are no visible buttons for the user. 1. Additional switch(es) or sensor(s) which are located under the Z-axes control device's swivel point. This device can measure at least one of the following joystick movements: a) In/out movement of Z-axes sensor structure when pressed at the middle of the Z-axes sensor structure b) In/out movement of Z-axes sensor structure when pressed at the end of the Z-axes sensor structure and normal movement reach the end allowed by z-axes sensor structure c) Side movements of Z-axes sensor structure Any functions can be with on/off states or with propositional output signal. 2. Additional switch(es) or sensor(s) which are located under the X/Y-axes swivel point. This can be integrated in the joystick base or can be a separate structure under the base. This device can measure at least one of the following joystick movements: a) Up or down movement of the handle. b) Turning of the handle. c) Movement of the base to any other direction Any functions can be with on/off states or with propositional output signal. Generally there are lots of joysticks with extra buttons, but there are no similar products on the market. None of them has hidden buttons or sensors under the z-axes sensor structure or under the X/Y axes swivel point. Neither of them measure the handle up/down position or rotation angle of the base. This invention can be implemented by using: 1. traditional a mechanical switch under the z-axis sensor device. This gives same the functionality as a button on the top of z-axis control device. 2. a pressure sensing foil under the z-axis sensor device. This could give output signal which is proportional to force used. 3. a hall sensor and magnet to sense the rotation angle of the base 4. a hall sensor and magnet to sense up/down position of the handle. If two directions are used springs could be used to keep the handle in the middle point when user doesn't touch the handle. 5. a pressure sensing foil under the joystick base. This could give an output signal which is proportional to the down force used. 6. a traditional mechanical switch under the joystick base.
