Safety net system including apparatus for securing

Abstract

A safety net system includes a mesh netting, first and second fixed support which are positioned either side of a loading dock or other dangerous zone. Clips secured to the mesh netting interact with connectors affixed to the fixed supports to place the netting in blocking position. An adjustable height stanchion is used as the fixed support in one embodiment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S)

(12) A first embodiment of the safety net system of the present invention is depicted in FIG. 1 generally at 20. Safety net system 20 includes a mesh safety net 30, first (60) and second (62) fixed supports positioned on each side of the dangerous region, and attachment means 40 for securing safety net 30 to fixed supports 60, 62. Mesh safety net 30 is made up of horizontal strap members 32 and vertical strap members 34. At least some, and, in the first embodiment, preferably each, of the horizontal strap members 32 along first peripheral edge 35 of net 30 are formed with a first series of horizontal extensions 36 and horizontal strap members 32 on opposite peripheral edge 37 are formed with a second series 38 of horizontal extensions (FIG. 10). Horizontal strap members 32 and vertical strap members are preferably woven fabric strips which are stitched together at their junctions, although other attachment techniques may be utilized without departing from the scope of the invention. The fabric of straps 32 and 34 may be cotton, polyester, nylon, polypropylene, UHMWPE, or aramid fibers, as the particular application warrants.

(13) First fixed support 60 has a first group of connectors 40a and the second fixed support 62 having a second group of connectors 40b. The and first and second series of clips 50a and 50b are engagable with first and second groups of connectors 40a, 40b, respectively. In the first embodiment depicted in FIG. 1, first and second series of clips 50a, 50b are attached to the ends of horizontal extensions 36 and 38, respectively as by a stitched loop reversed through slots 52 formed therein for this purpose.

(14) The first embodiment of attachment means 40 featuring connectors 40a, 40b and clips 50a, 50b are detailed in FIGS. 2-4. Connector or bracket 40a, 40b consists of a first planar portion 42 with a plurality of attachment slots or openings 43 and a second planar portion 44 forming an angle with first planar portion 42 at a first end 41a thereof. A pair of ears 46a, 46b extend from an upper and lower edge 45a, 45b, respectively of second planar portion 44 and serve to stabilize clips 50, 50b when engaged therewith. Connectors 40a, 40b are designed to be bolted to overhead door rails 60, 62 (FIG. 2).

(15) Each of clips 50a, 50b comprises a first planar member 52 and a second orthogonal arm member 54. First planar member 52 extends from a first end 53 of second orthogonal arm member 54 which third angulated member 56 extends from the opposite end 55 of second orthogonal arm member 54 at an angle . When clip 50a, 50b is engaged with connector 40a, 40b, first planar member 52 forms a right angle with first planar portion 42 (see FIG. 4).

(16) Not all overhead door rails have sufficient rigidity to adequately support connectors 40a, 40b and the associated safety net system 20. For other non-overhead door applications, such rails are not available. Second embodiment 40 shown in FIGS. 5-8 have a more robust design. Attachment means 40 utilizes the same clips 50a, 50b as the previous embodiment but beefed up connectors 40a, 40b. As with the first embodiment, first planar portion 42 has a second planar portion 44 extending from first end 43 forming an angle therewith. Third planar portion 46 extends from second end 45 and has a plurality of attachment openings 47 which permit bracket 40 to be bolted directly to a wall, column, beam or the like. Ears 46a, 46b extend from upper and lower edges 45a and 45b of second planar portion 44, respectively. Reinforcement bar 48 is welded at first end 49a to first planar portion 42 and at second end 49b to third planar portion 46 (FIG. 8).

(17) Third embodiment 40a of bracket is shown in FIG. 9. This design is similar to second embodiment 40 with the exception that the flate plate of the previous embodiment is replaced with circular bar 48 and an eyelet 41 is formed in finger 41a to facilitate connection with a conventional spring clip 50 shown in the FIG. 10 embodiment.

(18) Yet another embodiment of safety net system 20 is depicted in FIG. 10. As depicted in this embodiment, strap extensions 38 are only formed on some of the horizontal strap members 32. Each of the extensions 38 are provided with adjustment clips 70 which permit the length of extensions 38 and therefore, the tension of safety net 20 to be adjusted. As an alternative to the clips 50a, 50b shown in the earlier embodiment, this embodiment utilizes a conventional spring clip 50 which engages eyelet 40 which extends from a side surface 82 of stanchion 80. Stanchion 80 includes a base 84 which may be bolted to the floor, base 84 including a stump 86 extending upwardly from the upper surface 85 of base 84. Removable upper post 88 fits over stump 86 and is secured thereto by a pull pin 89 in one of a series of holes in stump 86 making stanchion 80 adjustable in height. Further, should a wide load extending over the sides of a fork lift need to be shuttled to or from a loading bay, upper post 88 can be removed so that it does not interfere with the movement of the oversized load.

(19) Various changes, alternatives, and modifications will become apparent to a person of ordinary skill in the art after a reading of the foregoing specification. It is intended that all such changes, alternatives, and modifications as fall within the scope of the appended claims be considered part of the present invention.
