Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • The subject invention is a post assembly for placement upon a dirt retaining of a trench box or of a slide rail shoring system wall for supporting guardrails around an excavation site.
  • 2. Description of the Prior Art
  • When persons work in an area surrounding a trench box at a construction site, guardrails are often provided to prevent accidental falls into the excavation below.
  • Such post assemblies typically include an inverted U-shaped saddle having a top portion with a front leg and a rear leg each integrally connected to and extending from the top portion and the rear leg being spaced from the front leg to define an opening for receiving the retaining wall. The saddle has a constant thickness through the legs and the top portion thereof. A post member extends upwardly from the top portion of the U-shaped saddle and a plurality of guardrail channels are disposed on the post member and extend perpendicularly to the post member for receiving and supporting guardrails.
  • Two examples of such assemblies are disclosed in U.S. Pat. No. 6,039,150 to Palmer (hereinafter Palmer) and U.S. Pat. No. 5,829,549 to Flynn (hereinafter Flynn).
  • The Palmer patent discloses an assembly having a U-shaped saddle and a post member that extends upwardly from the U-shaped saddle and a plurality of guardrail channels are disposed on the post member for receiving and supporting guardrails.
  • The Flynn patent discloses an assembly having an inverted U-shaped saddle having a top portion with a front leg and a rear leg each integrally connected to and extending from the top portion and the rear leg being spaced from the front leg to define an opening for receiving the retaining wall. The saddle has a constant thickness through the legs and the top portion thereof. A plurality of guardrail channels are disposed on a post member for receiving and supporting guardrails.
  • Although these prior post assemblies support and receive guardrails surrounding a retaining wall, they are fabricated from some specially formed components and parts as distinguished from commodity-type, off-the-shelf metal parts. Such prior art post assemblies also incorporate expensive fabrication techniques and steps.
  • SUMMARY OF THE INVENTION AND ADVANTAGES
  • The invention provides such a post assembly distinguished by at least one U-shaped reinforcing plate extending about the top portion and legs of the U-shaped saddle for strength and support.
  • Accordingly, since the saddle has a constant thickness through the legs and the top portion thereof, the saddle can be formed and bent from a single sheet of stock rather than being welded or otherwise formed of thicker pieces that cannot be easily bent. This allows for a more cost effective product that is easier to manufacture. Also, with the addition of the U-shaped reinforcing plates the saddle remains strong and supportive.

  • DETAILED DESCRIPTION OF THE INVENTION
  • Referring to the Figures, wherein like numerals indicate corresponding parts throughout the several views, a panel fence post assembly 20 constructed in accordance with the subject invention is generally shown (FIGS. 1 and 2) for placement upon a retaining wall 22 (generally indicated) having a top 24 extending between an inside surface 26 and an outside surface 28.
  • The assembly comprises an inverted U-shaped saddle 30 generally indicated having a top portion 32 with a front leg 34 and a rear leg 36 each integrally connected to and extending from the top portion 32 with the rear leg 36 spaced from the front leg 34 to define an opening for receiving the retaining wall 22. The top portion 32 of the saddle 30 engages the top 24 of the retaining wall 22 and the front leg 34 engages the inside surface 26 and the rear leg 36 engages the outside surface 28 of the retaining wall 22. The saddle 30 has a constant thickness through the legs 34, 36 and the top portion 32.
  • A plurality of bolts 38 extend through the rear leg 36 for perpendicularly abutting the outside of the retaining wall 22 for clamping the retaining wall 22 between the bolts 38 and the front leg 34 of the U-shaped saddle 30. A pair of U-shaped reinforcing plates 40 extend about the top portion 32 and the legs 34, 36 of the U-shaped saddle 30 and are spaced from one another on either side of the plurality of bolts 38 for additional strength and support. The U-shaped saddle 30 is bent from a single sheet of stock rather than being welded or otherwise formed of thicker pieces that cannot be easily bent.
  • A rubber grip 42 covers the inside of the front leg 34 for preventing slipping on the retaining wall 22.
  • A post member 44 is generally shown (FIGS. 1 and 2) and extends upwardly from the longitudinal center of the top portion 32 of the U-shaped saddle 30 (FIG. 4) and the post member 44 includes a bottom post 46 and a top post 48. The bottom post 46 is generally indicated and is defined by a hollow tube. The bottom post 46 has a rectangular or square cross section and with a front wall 50 opposite from a rear wall 52 and with two side walls 54. Each of the side walls 54 defines a bottom post hole 56. A rectangular strip 58 extends along the rear wall 52 for reinforcing the strength and stiffness of the bottom post 46 member 44.
  • As illustrated in FIG. 4, the front and rear walls 50, 52 of the bottom post 46 are spaced a post distance p and the legs 34, 36 of the U-shaped saddle 30 are spaced apart a saddle distance s that is greater than the post distance p. The bottom post 46 extends upwardly from the top portion 32 of the U-shaped saddle 30 with the front and rear walls 50, 52 parallel to the legs 34, 36 of the U-shaped saddle 30 and the bottom post 46 is disposed at a position on the top portion 32 offset from the front leg 34 and closer to the rear leg 36 so that the distance from the rear leg 36 to the rear wall 52 of the bottom post 46 is less than the distance from the front leg 34 to the front wall 50 of the bottom post 46.
  • The top post 48 generally indicated is defined by a hollow tube having a rectangular or square cross section and having a front side 60 opposite from a rear side 62 and having two sides 64 each defining a top post hole 66. The top post 48 has a larger cross section than the bottom post 46 for sliding the top post 48 downward and onto the bottom post 46 with the front side 60 of the top post 48 in sliding engagement with the front wall 50 of the bottom post 46 and with the rear side 62 of the top post 48 in sliding engagement with the rear wall 52 of the bottom post 46 with the bottom post holes 56 aligned with the top post holes 66. As shown in FIG. 3, a keeper pin 68 extends through the bottom post 46 and top post holes 56, 66 for preventing telescoping movement between the top post 48 and bottom post 46.
  • A plurality of guardrail channels 70 generally indicated each being C-shaped have a back 72 and a top surface 74 and a bottom surface 76 and are spaced from one another and mounted on the rear side 62 of the top post 48 with the back 72 engaging the rear side 62 and extending perpendicularly to the top post 48 for receiving and supporting guardrails. The guardrail channels 70 each have an open slot and a rectangular periphery extending transversely of the channels to distal ends spaced from the sides 64 of the top post 48 for receiving standard building studs 78 (e.g., wood 2×4's) perpendicular to the top post 48. A pair of such studs 78 abut one another at the center of each guardrail channel 70 and extend perpendicularly to the top post 48.
  • The top of the guardrail channels 70 each define a pair of nail holes 80 spaced from one another on either side 64 of the top post 48 for receiving nails for securing a guardrail stud 78 in the guardrail channel 70. A pair of rectangular reinforcing plates 82 are disposed on the back 72 of each guardrail channel 70 and are spaced from one another and from either side 64 of the top post 48.
  • Obviously, many modifications and variations of the present invention are possible in light of the above teachings and may be practiced otherwise than as specifically described while within the scope of the appended claims. That which is prior art in the claims precedes the novelty set forth in the “characterized by” clause. The novelty is meant to be particularly and distinctly recited in the “characterized by” clause whereas the antecedent recitations merely set forth the old and well-known combination in which the invention resides.
