Definitions

  • This invention relates to a three-position switch. More specifically, this invention relates to a three-position switch which is employable for a double purpose including preparation for operation of a robot and emergency stop of a robot and which is mounted on an operation board employable for teaching a robot.
  • a three-position switch is defined as a switch which is in an open or off position, when the push button thereof is not pressed or is in the free position, turns to a closed or on position, when the push button thereof is pressed with a moderate degree of pressure, and turns to an open or off position again, when the push button thereof is pressed with a large degree of pressure.
  • An operation board employable for teaching a robot is usually designed to be held in the palm of a hand (usually a left hand) of an operater and the push buttons thereof are designed to be pressed with a finger of the other hand (usually a right hand) of the operater.
  • a switch for preparation for operation of a robot is arranged on an operation board for teaching a robot at a location at which a finger of a hand (usually a left hand) which holds the operation board, automatically closes the switch, when the operation board is held in the palm of a hand. Therefore, a switch for preparation for operation of a robot is automatically brought to a ready position, when an operation board for teaching a robot is held with a hand of an operater.
  • an operation board for teaching a robot is operable exclusively during a period in which the operation board is held with a hand (usually a left hand) and the switch for preparation for operation of a robot is automatically closed by a finger of the hand.
  • an operation board for teaching a robot is not operable, during a period in which the operation board is not held with a hand (usually a left hand) and the switch for preparation for operation of a robot is open.
  • a three-position switch is suitable for a switch which is employable for a double purpose including preparation for operation of a robot and emergency stop of a robot and which is mounted on an operation board employable for teaching a robot.
  • a three-position switch is in an open position, while it is not held with a hand, turns to a closed position, when it is held with a hand and resultantly its switch for preparation for operation of a robot is pressed with a moderate degree of pressure, and turns to an open position again, when the holder thereof is surprised by an emergency and he grips the three-position switch with a large degree of pressure.
  • the three-position switches available in the prior art are large in size and none of them can be employed as a switch which is employable for a double purpose including preparation for operation of a robot and emergency stop of a robot and which is mounted on an operation board employable for teaching a robot.
  • a switch which is employable for a double purpose including preparation for operation of a robot and emergency stop of a robot and which is mounted on an operation board employable for teaching a robot is desired to be small enough to be held in the palm of a hand of an operater.
  • the object of this invention is to provide a three-position switch which has a function to be in an open position, while the push button thereof is not pressed and the switch is in the free position, turns to a closed position, when the push button thereof is pressed with a moderate degree of pressure, and turns to an open position again, when the push button thereof is pressed with a large degree of pressure and which is small in size.
  • a three-position switch in accordance with the first embodiment of this invention is provided a push button 11 elastically supported by a double spring 21 and 22, a switch operating rod 3 inwardly extending from the push button 11 in the direction approximately perpendicular to the push button 11 and having a lateral projection 31 projecting at the front end thereof, a normally-off switch 41 which operates in the direction approximately perpendicular to the direction in which the push button 11 moves and which turns to a closed position by a pressing action with a moderate degree of pressure of the push button 11, which pressing action causes the projection 31 to press the button of the normally-off switch 41 and which is in an open position, during the period in which the push button 11 is not pressed or is in the free position and during the period in which the push button 11 is pressed with a large degree of pressure.
  • the foot of the projection 31 is preferably made large to make the operation of the normally-off switch 41 smooth.
  • a three-position switch in accordance with the second embodiment of this invention is provided a push button 12 elastically supported by a spring 23, a combination of a normally-off switch 42 and a normally-on switch 43 which are connected in series to each other and which are arranged to face the push button 12, a normally-off switch operating means 5 which turns the normally-off switch 42 to a closed position, when the push button 12 is pressed with a moderate degree of pressure and when the push button 12 is pressed with a large degree of pressure, and a normally-on switch operating means 6 which turns the normally-on switch 43 to an open position, when the push button 12 is pressed with a large degree of pressure.
  • a push button 11 is a bar.
  • the reason why the push button 11 is a bar is to enable one hand of an operater to hold the three-position switch in the palm of his hand, when the three-position switch is employed as a switch for preparation for operation of a robot and for emergency stop of a robot and which is mounted on an operation board for teaching a robot.
  • the push button of a bar 11 is elastically supported by a double spring, so that it is suspended in the free position.
  • the double spring consists of a weak spring 21 and a strong spring 22 both of which are wound on a single bobbin. When the double spring is pressed with a moderate degree of pressure, the weak spring 21 deforms, and when the double spring is pressed with a large degree of pressure, the both springs 21 and 22 deform.
  • a switching rod 3 inwardly extends from the push button 11 in the direction approximately perpendicular to the push button 11 and has a projection 31 which laterally projects at the front end thereof.
  • the projection 31 has a shape of trapezoid, so that the move of a normally-off switch 41 to be referred to later is made smooth.
  • the normally-off switch 41 turns to a closed position exclusively when the push button 11 is pressed with a moderate degree of pressure to cause the projection 31 to press a button of the normally-off switch 31.
  • the button of the normally-off switch 41 preferably has a shape of trapezoid for the purpose to make the move of the normally-off switch 41 smooth.
  • Fig. 1 illustrates the free position in which the push button 11 is not pressed. In this position, the normally-off switch 41 is in an open position.
  • the normally-off switch 41 turns to a closed position, when the push button 11 is pressed with a moderate degree of pressure.
  • the normally-off switch 41 turns to an open position again, when the push button 11 is pressed with a large degree of pressure.
  • a three-position switch in accordance with the first embodiment of this invention has a function to be in an open position, when the push button thereof is not pressed, to be in a closed position, when the push button thereof is pressed with a moderate degree of pressure, and to be in an open position again, when the push button thereof is pressed with a large degree of pressure, and is small in size. Therefore, the three-position switch in accordance with the first embodiment of this invention can be employed as a switch employable for a double purpose including preparation for operation of a robot and emergency stop of a robot and which is mounted on an operation board for teaching a robot.
  • a push button 12 is a bar.
  • the reason why the push button 12 is a bar is to enable one hand of an operater to hold the three-position switch in the palm of his hand, when the three-position switch is employed as a switch which is employable for preparation for operation of a robot and for emergency stop of a robot and which is mounted on an operation board for teaching a robot and to make it possible to operate two independent switches with one push button.
  • the push button 12 is elastically supported by a spring 23.
  • a normally-off switch 42 and a normally-on switch 43 are connected in series to each other. This series circuit is in an open position, while the push button 12 is not pressed.
  • a normally-off switch operating means 5 is a spring having a long operating span.
  • the normally-off switch operating means 5 keeps the normally-off switch 42 in a closed position, during the period in which the push button 12 is pressed with a moderate degree of pressure and during the period in which the push button 12 is pressed with a large degree of pressure.
  • a normally-on switch operating means 6 is a projection projected from the push button 12.
  • the normally-on switch operating means 6 turns the normally-on switch 43 to an open position, when the push button 12 is pressed with a large degree of pressure.
  • a three-position switch in accordance with the second embodiment of this invention has a function to be in an open position, when the push button thereof is not pressed, to be in a closed position, when the push button thereof is pressed with a moderate degree of pressure, and to be in an open position again, when the push button thereof is pressed with a large degree of pressure, and is small in size. Therefore, the three-position switch in accordance with the second embodiment of this invention can be employed as a switch employable for a double purpose including preparation for operation of a robot and emergency stop of a robot and which is mounted on an operation board employable for teaching a robot.
  • either of the three-position switches in accordance with this invention has a function to be in an open position, when the push button thereof is not pressed, to be in a closed position, when the push button thereof is pressed with a moderate degree of pressure, and to be in an open position again, when the push button thereof is pressed with a large degree of pressure, and is small in size. Therefore, either of the three-position switches in accordance with this invention can be employed as a switch employable for a double purpose including preparation for operation of a robot and emergency stop of a robot and which is mounted on an operation board employable for teaching a robot.
