Abstract
Abstract A multistage pushbutton device used to drive a push switch has a base, a first and second stage pushbutton members and drive members to drive the push switch. The first and second stage pushbutton members have first and second elastic arms respectively connected with the base at the one end thereof and a pushbutton is respectively provided on the other end of the arm. An elastic second arm is longer than said first arm and is placed at the position behind the first arm where it does not overlap the first arm in the back and forth direction and at least the part of said second arm overlaps at least the part of said first pushbutton in the back and forth direction.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
196 words
A multistage pushbutton device used to drive at least one push switch comprising: a base, at least one first stage pushbutton member which includes a first elastic arm connected with the base at one end thereof and being capable of flexing movement back and forth and a first pushbutton provided on the other end of the arm, at least one second stage pushbutton member which has an elastic second arm longer than said first arm connected with the base at one end thereof and being capable of flexing movement back and forth in a manner which does not overlap the first arm and a second pushbutton mounted at the other end of the second arm, said movement of said second arm being in a manner which overlaps at least part of said first pushbutton, a first drive member projecting from the back of the first stage pushbutton member which moves in the direction nearly perpendicular to the direction of pushing operation of the first pushbutton, a second drive member projecting from the back of the second stage pushbutton member which moves in the direction nearly perpendicular to the direction of pushing operation of the second pushbutton.
Claim 2
Dependent Claim
196 words
A multistage pushbutton device used to drive at least one push switch comprising: a base, at least one first stage pushbutton member which includes a first elastic arm connected with the base at one end thereof and being capable of flexing movement back and forth and a first pushbutton provided on the other end of the arm, at least one second stage pushbutton member which has an elastic second arm longer than said first arm connected with the base at one end thereof and being capable of flexing movement back and forth in a manner which does not overlap the first arm and a second pushbutton mounted at the other end of the second arm, said movement of said second arm being in a manner which overlaps at least part of said first pushbutton, a first drive member projecting from the back of the first stage pushbutton member which moves in the direction nearly perpendicular to the direction of pushing operation of the first pushbutton, a second drive member projecting from the back of the second stage pushbutton member which moves in the direction nearly perpendicular to the direction of pushing operation of the second pushbutton.
Claim 3
Dependent Claim
39 words
The multistage pushbutton device used to drive a push switch as claimed in claim 1 wherein: a plurality of said first stage pushbutton members are provided, said second arm is implanted behind both adjacent sides of the first pushbuttons.
Claim 4
Dependent Claim
207 words
A multistage pushbutton device used to drive at least one push switch comprising: a base, a plurality of first stage pushbutton members which respectively include a first elastic arm connected with the base at one end thereof and being capable of flexing movement back and forth and a first pushbutton provided on the other end of the first arm, at least one second stage pushbutton member which has an elastic second arm longer than said first arm connected with the base at one end thereof and being capable of flexing movement back and forth in a manner which is not right behind the first arm and a second pushbutton mounted at the other end of the second arm, at least the one of adjacent sides of the first pushbuttons conceals at least the part of said second arm in the front view of the base, a first drive member projecting from the back of the first stage pushbutton member which moves in the direction nearly perpendicular to the direction of pushing operation of the first pushbutton, a second drive member projecting from the back of the second stage pushbutton member which moves in the direction nearly perpendicular to the direction of pushing operation of the second pushbutton.
Claim 5
Dependent Claim
207 words
A multistage pushbutton device used to drive at least one push switch comprising: a base, a plurality of first stage pushbutton members which respectively include a first elastic arm connected with the base at one end thereof and being capable of flexing movement back and forth and a first pushbutton provided on the other end of the first arm, at least one second stage pushbutton member which has an elastic second arm longer than said first arm connected with the base at one end thereof and being capable of flexing movement back and forth in a manner which is not right behind the first arm and a second pushbutton mounted at the other end of the second arm, at least the one of adjacent sides of the first pushbuttons conceals at least the part of said second arm in the front view of the base, a first drive member projecting from the back of the first stage pushbutton member which moves in the direction nearly perpendicular to the direction of pushing operation of the first pushbutton, a second drive member projecting from the back of the second stage pushbutton member which moves in the direction nearly perpendicular to the direction of pushing operation of the second pushbutton.
Claim 6
Dependent Claim

Claim 10
Independent Claim
226 words
A method for manufacturing a multistage pushbutton device which includes multistage pushbuttons mounted on a base and a drive member provided with the pushbuttons respectively at the back side thereof and is used to drive at least one push switch comprising the following steps: preparing a first member for molding which includes cavities corresponding to the front portions of the base, of a first arm connected with the base at the one end thereof, of a first pushbutton provided at the other end of the first arm, and of a second pushbutton connected to the base at the more distant position from the front portion of the base than the first pushbutton, preparing a second member for molding which includes cavities corresponding to the other surface of the base except said front portion and to each back portion of the first pushbutton and the second pushbutton, preparing a third member for molding which is used for forming the front portion of the second arm which connects the second pushbutton to the base and the back portion of the first pushbutton which is placed in front of the second arm, assembling these members for molding to form the space corresponding to the shape of the multistage pushbutton device and for filling material in the space, and pouring a material suitable for the pushbutton device into said space.
