Abstract

A side entry bar apparatus is provided for mounting on a bottom of a trailer and prevents or bars a motor vehicle from entering the space under the floor of the trailer from the side of the trailer. The apparatus includes a plurality of vertically oriented support bars, a plurality of longitudinally and horizontally oriented support bars, and a plurality of transversely and horizontally oriented support bars. The respective bars are connected together, such as by welding, to form a rigid cage structure. A plurality of trailer attachment plates are connected to the respective top ends of the vertically oriented support bars to attach the cage structure to the bottom of the trailer.

Claims

1. A side entry bar apparatus for mounting on a bottom of a trailer, comprising:

a first set of a plurality of first vertically oriented support bars, each of which has a top end and a bottom end,

a first longitudinally and horizontally oriented support bar connected to said respective bottom ends of said first vertically oriented support bars,

a second set of a plurality of second vertically oriented support bars, each of which has a top end and a bottom end,

a second longitudinally and horizontally oriented support bar connected to said respective bottom ends of said second vertically oriented support bars,

a plurality of transversely and horizontally oriented support bars connected between said first longitudinally and horizontally oriented support bar and said second longitudinally and horizontally oriented support bar, and

a plurality of trailer attachment plates connected to said respective top ends of said first vertically oriented support bars and said second vertically oriented support bars, said apparatus further including;

a first set of a plurality of first obliquely oriented support bars, each of which has a top end and a bottom end, wherein bottom ends of said first obliquely oriented support bars are connected to opposite ends of said first longitudinally and horizontally oriented support bar,

a second set of a plurality of second obliquely oriented support bars, each of which has a top end and a bottom end, wherein bottom end of said second obliquely oriented support bars are connected to opposite ends of said second longitudinally and horizontally oriented support bar, and

a plurality of additional trailer attachment plates connected to said respective top ends of said first obliquely oriented support bars and said second obliquely oriented support bars, and

wherein said plurality of transversely and horizontally oriented support bars connected between said first longitudinally and horizontally oriented support bar and said second longitudinally and horizontally oriented support bar are longitudinally spaced from each other and intermedially spaced from the opposite ends of said first longitudinally and horizontally oriented support bar and said second longitudinally and horizontally oriented support bar.

2. The apparatus of claim 1 wherein:

the trailer has a trailer width, and said transversely and horizontally oriented support bars have a transverse bar length which is less than the trailer width.

3. The apparatus of claim 1 wherein:

the bottom of the trailer floor is spaced above the ground by a trailer floor height,

said first vertically oriented support bars and said second vertically oriented support bars have a vertical bar height, and

said vertical bar height is less than said trailer floor height.

4. The apparatus of claim 1 wherein said trailer attachment plates include bolt reception channels, and wherein said trailer attachment plates are attached to bottom portions of the trailer using attachment bolts that are threaded through said bolt reception channels.
