Abstract

A cable accumulator for a plurality of input cables and at least one output cable includes a bracket and a carrier member slidably coupled with the bracket. The carrier member includes a frame having a first end and a second end. The second end of the frame is coupled to the at least one output cable. A plurality of connecting members are slidably coupled with a pin member. The plurality of connecting members slide relative to the pin member independently of each other. Actuation of any one of the input cables causes the respective connecting member to pull the pin member to slide the carrier member relative to the bracket and to actuate the at least one output cable. Further, the respective connecting members coupled to non-actuated input cables slide relative to the pin member in response to actuation of any one of the plurality of input cables.

First claim

The invention claimed is:

1. A cable accumulator for a plurality of input cables and at least one output cable, the cable accumulator comprising:
a bracket having an input end and an output end; and
a carrier member slidably coupled with the bracket such that the carrier member is slidable relative to the bracket between the input end and the output end, the carrier member including:
a frame having a first end and a second end, wherein the second end of the frame is coupled to the at least one output cable;
a pin member coupled to the frame between the first end and the second end; and
a plurality of connecting members spaced apart from each other and slidably coupled with the pin member, wherein the plurality of connecting members is adapted to slide relative to the pin member independently of each other, wherein each input cable from the plurality of input cables is coupled to a respective connecting member from the plurality of connecting members;
wherein an actuation of any one of the plurality of input cables causes the respective connecting member to pull the pin member in order to slide the carrier member relative to the bracket and to actuate the at least one output cable; and
wherein the respective connecting members coupled to non-actuated input cables from the plurality of input cables are configured to slide relative to the pin member in response to actuation of any one of the plurality of input cables.

2. The cable accumulator of claim 1 , wherein each of the plurality of connecting members defines a slot receiving the pin member therethrough, such that each of the plurality of connecting members is slidable relative to the pin member along a length of the slot.

3. The cable accumulator of claim 2 , wherein a length of each slot is substantially equal to a length of travel of the carrier member due to actuation of any one of the plurality of input cables.

4. The cable accumulator of claim 1 , wherein the pin member is fixedly coupled to the frame.

5. The cable accumulator of claim 1 , further comprising a biasing member disposed between each of the plurality of connecting members and the first end of the frame.

6. The cable accumulator of claim 5 , wherein the biasing member is adapted to extend to maintain tension in a non-actuated input cable as the carrier member slides in response to an actuated input cable.

7. A working machine comprising:
a chassis;
a plurality of ground engaging means adapted to support the chassis over a working surface; and
a control mechanism adapted to control at least one operational parameter of the working machine, the control mechanism comprising:
a plurality of input levers;
a cable accumulator, the cable accumulator including:
a bracket having an input end and an output end; and
a carrier member slidably coupled with the bracket such that the carrier member is slidable relative to the bracket between the input end and the output end, the carrier member including:
a frame having a first end and a second end;
a pin member coupled to the frame between the first end and the second end; and
a plurality of connecting members spaced apart from each other and slidably coupled with the pin member, wherein the plurality of connecting members are adapted to slide relative to the pin member independently of each other;
a plurality of input cables, each input cable from the plurality of input cables coupled to a respective connecting member from the plurality of connecting members, each of the plurality of input cables further operatively coupled to a respective input lever from the plurality of input levers; and
at least one output cable, the at least one output cable coupled to the second end of the frame, wherein upon actuation the at least one output cable controls the at least one operational parameter of the working machine;
wherein an actuation of any one of the plurality of input cables causes the respective connecting member to pull the pin member in order to slide the carrier member relative to the bracket and to actuate the at least one output cable; and
wherein the respective connecting members coupled to non-actuated input cables from the plurality of input cables are configured to slide relative to the pin member in response to actuation of any one of the plurality of input cables.

8. The working machine of claim 7 , wherein each of the plurality of connecting members defines a slot receiving the pin member therethrough, such that each of the plurality of connecting members is slidable relative to the pin member along a length of the slot.

9. The working machine of claim 8 , wherein a length of each slot is substantially equal to a length of travel of the carrier member due to actuation of any one of the plurality of input cables.

10. The working machine of claim 7 , wherein the pin member is fixedly coupled to the frame.

11. The working machine of claim 7 , further comprising a biasing member disposed between each of the plurality of connecting members and the first end of the frame.

12. The working machine of claim 11 , wherein the biasing member is adapted to extend to maintain tension in a non-actuated input cable as the carrier member slides in response to an actuated input cable.

13. A control mechanism for a machine, the control mechanism comprising:
a cable accumulator comprising:
a bracket having an input end and an output end; and
a carrier member slidably coupled with the bracket such that the carrier member is slidable relative to the bracket between the input end and the output end, the carrier member including:
a frame having a first end and a second end;
a pin member fixedly coupled to the frame between the first end and the second end;
a plurality of connecting members spaced apart from each other and slidably coupled with the pin member, wherein the plurality of connecting members are adapted to slide relative to the pin member independently of each other, and wherein each of the plurality of connecting members defines a slot receiving the pin member therethrough, such that each of the plurality of connecting members is slidable relative to the pin member along a length of the slot; and
a plurality of biasing members corresponding to the plurality of connecting members, the plurality of biasing members being disposed between each of the plurality of connecting members and the first end of the frame;
a plurality of input cables passing through the input end of the bracket, each input cable from the plurality of input cables coupled to a respective connecting member from the plurality of connecting members; and
at least one output cable passing through the output end of the bracket, the at least one output cable coupled to the second end of the frame;
wherein an actuation of any one of the plurality of input cables causes the respective connecting member to pull the pin member in order to slide the carrier member relative to the bracket and to actuate the at least one output cable; and
wherein the respective connecting members coupled to non-actuated input cables from the plurality of input cables are configured to slide relative to the pin member in response to actuation of any one of the plurality of input cables.

14. The control mechanism of claim 13 , wherein a length of each slot is substantially equal to a length of travel of the carrier member due to actuation of any one of the plurality of input cables.

15. The control mechanism of claim 13 , wherein the biasing member is adapted to extend to maintain tension in a non-actuated input cable as the carrier member slides in response to an actuated input cable.
