Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
205 words
A single lever control apparatus having a housing for operating the clutch and throttle of an engine comprising a transmission shaft (6) adjustably carrying a control lever (1), a clutch operating member and a throttle operating member to be driven by said transmission shaft, said transmission shaft (6) carrying a throttle operating gear having teeth and a locking face, said throttle operating member having a V-shaped form being rotatably supported on a stationary pivot (23) at one end, and having teeth (26, 27) oppositely at both ends and a locking face (28) between them, the locking face of said throttle operating member being engageable with the locking face (20) of said throttle operating gear to lock said throttle operating member when said control lever (1) is in neutral position, the teeth of said throttle operating gear being meshable with the teeth (26) of said throttle operating member to rotate said throttle operating member when said control lever (1) is pivoted toward one direction, the teeth of said throttle operating gear being meshable with the teeth (27) of said throttle operating member to rotate said throttle operating member in the same direction as above mentioned when said control lever 1 is pivoted toward the other direction.
Claim 2
Dependent Claim
205 words
A single lever control apparatus having a housing for operating the clutch and throttle of an engine comprising a transmission shaft (6) adjustably carrying a control lever (1), a clutch operating member and a throttle operating member to be driven by said transmission shaft, said transmission shaft (6) carrying a throttle operating gear having teeth and a locking face, said throttle operating member having a V-shaped form being rotatably supported on a stationary pivot (23) at one end, and having teeth (26, 27) oppositely at both ends and a locking face (28) between them, the locking face of said throttle operating member being engageable with the locking face (20) of said throttle operating gear to lock said throttle operating member when said control lever (1) is in neutral position, the teeth of said throttle operating gear being meshable with the teeth (26) of said throttle operating member to rotate said throttle operating member when said control lever (1) is pivoted toward one direction, the teeth of said throttle operating gear being meshable with the teeth (27) of said throttle operating member to rotate said throttle operating member in the same direction as above mentioned when said control lever 1 is pivoted toward the other direction.
Claim 3
Dependent Claim
129 words
The control apparatus as set forth in claim 1, wherein said clutch operating member (30) is rotatably supported on said stationary pivot (23) and has recess (32) and arcuate concave faces (33, 34) in symmetrical relation with each other, a tooth (41) of a clutch operating gear to be driven by said transmission shaft being meshable with said recess (32) when said control lever (1) is in neutral position, said tooth (41) being disengaged from said recess (32) and an arcuate concave face (33 or 34) of said clutch operating member being engageable with the outer peripheral surface (42 or 43) of said clutch operating gear to lock said clutch operating member when said lever (1) is pivoted a given angle from neutral position toward forward or backward position.
Claim 4
Dependent Claim
39 words
The control apparatus as set forth in claim 2, wherein said throttle operating member is locked while said clutch operating member is in operation and said clutch operating member is locked while said throttle operating member is in operation.
Claim 5
Dependent Claim
37 words
The control apparatus as set forth in claim 3, wherein said clutch operating member has a recess (32'') facing to said recess (32) and said clutch operating gear (40) is engaged with said transmission shaft (6) removably.
Claim 6
Dependent Claim
53 words
The control apparatus as set forth in claim 3, wherein said transmission shaft (6) is formed cylindrically a shaft (44) of said clutch operating gear extends through said transmission shaft slidably, and said shaft (44) when depressed in the axial direction permits said clutch operating member to disengage from said clutch operating gear.
Claim 7
Dependent Claim
103 words
The control apparatus as set forth in claim 5, wherein said clutch operating member (30) has a stopper (21) having a recess (37) and when said shaft (44) of the clutch operating gear slides through said shaft (6) to disengage said clutch operating gear from said transmission shaft when said control lever (1) is in neutral position, a locking shaft (44'') of said clutch operating gear is fixed into said recess (37) to lock said clutch operating member, said stopper prevents said clutch operating gear from disengaging from said clutch operating member when the lever (1) is shifted in forward or backward direction.
Claim 8
Dependent Claim
120 words
The control apparatus as set forth in claim 6, wherein said clutch operating gear engages with said transmission shaft when the slender parts (15, 15'') of said transmission shaft or the projections of a throttle operating gear (18'') are fixed into the recesses (48, 48'') of said clutch operating gear, and the end face of said slender parts (15, 15'') or the projections of the throttle operating gear (18'') contact with the brim face (43'') to prevent said clutch operating gear from engaging with said transmission shaft when said slender parts (15, 15'') or the projections of said throttle operating gear (18'') disengage from said recesses (48, 48'') and said control lever 1 is pivoted toward forward and backward positions.
Claim 9
Dependent Claim
40 words
The control apparatus as set forth in claim 7, wherein said clutch operating member is formed with an recess (32'') in symmetrical relation to said recess (32), and said clutch operating gear (40) are fixed into said transmission shaft removably.
Claim 10
Dependent Claim
68 words
The control apparatus as set forth in claim 8, wherein a brim (9) is integrally formed with said transmission shaft, and notches (10, 11, 12) are formed at the outer peripheral surface of said brim, and a column-like member (49) are fixed into said notches (10, 11, and 12) in turn when said control lever (1) is in neutral position, engaged completely in forward position and backward position.
