Abstract
An expansion tool for spreading the side walls of a partitioning track comprises first and second members each having a handle portion and a jaw portion. These members are coupled together so as to cause the jaw portions to compress when the handles are compressed. Coupled to each jaw portion is a spreading member each of which includes a contact or spreading surface. As the jaws are compressed, the contact surfaces move apart.
Claims7
An expansion tool for spreading the side walls of a longitudinal track member, said track member having a base and first and second side walls extending therefrom comprising:
- a first member having a first handle portion and a first jaw portion;
- a second member having a second handle portion and a second jaw portion;
- means coupling said first and second members at points intermediate thereof for moving said second jaw portion towards said first jaw portion when said first and second handle portions are compressed;
- first and second spreading members coupled to said first and second jaw portions respectively, said second jaw portion forcing said second spreading member away from said first spreading member when said first and second handle portions are compressed;
- said first spreading member comprising a base member coupled to said first jaw portion for engaging transversely the base of said track;
- said first spreading member further comprising a first contact member coupled to said base member and extending substantially perpendicularly therefrom for engaging one of said first and second side walls;
- said first spreading member further comprising a first overhang member coupled to an edge of said first contact member opposite said base member, said first overhang member extending substantially perpendicularly from said first contact member and in a direction away from said base member;
- said second spreading member comprising a second contact member for engaging the other of said first and second side walls;
- and
- adjusting means for coupling said second contact member to said second jaw portion and capable of altering the position of said second contact member with respect to said second jaw portion.
