Abstract
Abstract A support spike securely held by and extending from a wooden object. The spike is oriented parallel to the grain of the wooden object and has an elongated shaft. A hollow longitudinal opening is formed in the point end of the spike. The spike is driven into the wooden object to an extent that the hollow opening extends past the point of entry of the spike so that the wood in the hollow opening is compressed securely holding the spike in place. The spike is particularly useful when driven into the base of a Christmas tree in order to provide a means for holding the tree in an upright position.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
205 words
A support spike securely held by and extending from a wooden object, said spike being oriented about parallel to the grain in said wooden object and said spike comprising: a unitary elongated shaft having a driving end said driving end and a portion of the shaft extending outwardly from said wooden object, said shaft having a generally constant cross sectional shape along its length and having a maximum outside dimension of between three sixteenths and one-half inch as measured in a direction perpendicular to its longitudinal axis; a cylindrical, longitudinal opening formed in said elongated shaft, said opening containing only the wood passing therein as the spike was passed into the wooden object and said opening being axially oriented and extending from said point along said shaft a distance of at least one half inch, said opening having an inside diameter between one-fourth and three fourths of its maximum outside dimension and said opening terminating within said elongated shaft and said shaft being free from any longitudinal slits between the opening and the exterior of said shaft; and said spike being positioned in said wooden object a distance greater than the length of said longitudinal opening whereby the wood forced within said opening is compressed.
Claim 2
Dependent Claim
205 words
A support spike securely held by and extending from a wooden object, said spike being oriented about parallel to the grain in said wooden object and said spike comprising: a unitary elongated shaft having a driving end said driving end and a portion of the shaft extending outwardly from said wooden object, said shaft having a generally constant cross sectional shape along its length and having a maximum outside dimension of between three sixteenths and one-half inch as measured in a direction perpendicular to its longitudinal axis; a cylindrical, longitudinal opening formed in said elongated shaft, said opening containing only the wood passing therein as the spike was passed into the wooden object and said opening being axially oriented and extending from said point along said shaft a distance of at least one half inch, said opening having an inside diameter between one-fourth and three fourths of its maximum outside dimension and said opening terminating within said elongated shaft and said shaft being free from any longitudinal slits between the opening and the exterior of said shaft; and said spike being positioned in said wooden object a distance greater than the length of said longitudinal opening whereby the wood forced within said opening is compressed.

Claim 10
Dependent Claim
206 words
A support spike securely held by and extending from a Christmas tree base, said spide being oriented about parallel to the grain of said tree and said spike comprising: a unitary elongated shaft having a driving end and a point and a portion of the shaft thereof extending outwardly from said Christmas tree base, said shaft having a generally constant cross sectional shape along its length and having a maximum outside dimension of between three sixteenths and one-half inch as measured in a direction perpendicular to its longitudinal axis; a cylindrical, longitudinal opening formed in said elongated shaft, said opening containing only the wood passing therein as the spike was passed into the Christmas tree base, said opening being axially oriented and extending from said point along said shaft a distance of at least one half inch, said opening having an inside diameter between one-fourth and three fourths of its maximum outside dimension and said opening terminating within said elongated shaft and said shaft being free from any longitudinal slits between the opening and the exterior of said shaft; and said spike being positioned in said tree a distance greater than the length of said longitudinal opening whereby the wood forced within said opening is compressed.
Claim 11
Dependent Claim
206 words
A support spike securely held by and extending from a Christmas tree base, said spide being oriented about parallel to the grain of said tree and said spike comprising: a unitary elongated shaft having a driving end and a point and a portion of the shaft thereof extending outwardly from said Christmas tree base, said shaft having a generally constant cross sectional shape along its length and having a maximum outside dimension of between three sixteenths and one-half inch as measured in a direction perpendicular to its longitudinal axis; a cylindrical, longitudinal opening formed in said elongated shaft, said opening containing only the wood passing therein as the spike was passed into the Christmas tree base, said opening being axially oriented and extending from said point along said shaft a distance of at least one half inch, said opening having an inside diameter between one-fourth and three fourths of its maximum outside dimension and said opening terminating within said elongated shaft and said shaft being free from any longitudinal slits between the opening and the exterior of said shaft; and said spike being positioned in said tree a distance greater than the length of said longitudinal opening whereby the wood forced within said opening is compressed.
