Abstract
Abstract A mat is provided for practicing golf club swings. The mat is made of longitudinally spaced apart blocks held in staggered rows by wires passing through the opposite ends of the blocks. Select blocks have a slit at one end so the select blocks are not held by the wire at one end and, thus, may be pivoted upward about the wire at the other end to serve as knockdown indicators.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
233 words
In a golf practice device of the type having a rectangular mat formed of a plurality of rectangular blocks of approximately square cross-section, said blocks being arranged in a plurality of rows, the blocks in each row having their longer dimensions extending longitudinally of said mat, the ends of said adjacent blocks in each row being spaced apart a distance less than the length of said blocks, the blocks in adjacent rows being staggered relative to each other so that at least one side of each block in each row has an overlap area opposed to a corresponding overlap area of a side of a block in an adjacent row, and a plurality of parallel wires extending transversely of said mat and through holes in the overlap areas of one block in each of said rows, said wires retaining said blocks in assembled position, the improvement comprising at least a first said block being formed with a slit in a first end of said first said block extending inward from said first end of said first said block in the plane of said wires and extending inward to one said wire whereby said first block is disengaged from said one said wire and can be pivotted about another said wire extending through a second end of said first said block to an upright position above the plane of the top of said mat.
Claim 2
Dependent Claim

In a golf practice device of the type having a rectangular mat formed of a plurality of rectangular blocks of approximately square cross-section, said blocks being arranged in a plurality of rows, the blocks in each row having their longer dimensions extending longitudinally of said mat, the ends of said adjacent blocks in each row being spaced apart a distance less than the length of said blocks, the blocks in adjacent rows being staggered relative to each other so that at least one side of each block in each row has an overlap area opposed to a corresponding overlap area of a side of a block in an adjacent row, and a plurality of parallel wires extending transversely of said mat and through holes in the overlap areas of one block in each of said rows, said wires retaining said blocks in assembled position, the improvement comprising at least a first said block being formed with a slit in a first end of said first said block extending inward from said first end of said first said block in the plane of said wires and extending inward to one said wire whereby said first block is disengaged from said one said wire and can be pivotted about another said wire extending through a second end of said first said block to an upright position above the plane of the top of said mat.
Claim 3
Dependent Claim
131 words
A device according to claim 1 wherein said mat has a tee location for a tee and at least four additional said blocks are formed with slits at first ends of each said additional blocks extending inward from said first ends in the plane of said wires and extending inward to one of said wires whereby said additional blocks are disengaged from said one of said wires and can be individually pivotted about another said wire extending through second ends of said additional blocks to an upright position above the plane of the top of said mat, two of said additional blocks being behind and two ahead of said tee location, two of said additional blocks being on the far side and two on the near side of said tee location.
Claim 4
Dependent Claim
23 words
A device according to claim 2 which further comprises a tee at said tee location, said tee having a base below said mat.
Claim 5
Dependent Claim
165 words
A device according to claim 1 wherein the centermost of said plurality of blocks is formed with a slit formed in a first end of said centermost block extending inward from a first end of said centermost block in the plane of said wires and extending inward to one said wire whereby said centermost block is disengaged from said one said wire and can be pivotted about another said wire extending through a second end of said centermost block to an upright position above the plane of said mat, to permit pivotting of said centermost block between flat, intermediate and upright positions, whereby said centermost block may be positioned flat when said device is used with a ball or may be turned to intermediate position at about a 30° angle to the mat when said device is not used with a ball so that it may be struck with a golf club, said centermost block rebounding to upright position if it has been struck properly.
