  • Patent number: 9546455
    Abstract: A rig mat frame has at least two longitudinal frame members and at least two lateral frame members defining a deck insert opening therebetween. Each longitudinal frame member has a C-shaped channel facing the deck insert opening and extending along the length of the longitudinal frame member. At least one C-shaped channel has a longitudinally extending flange with a channel opening providing access into the C-shaped channel. A flange panel is removably fastened to the frame and closes the channel opening when the flange panel is fastened to the frame. A plurality of deck inserts are disposed within the frame and extend across the deck insert opening with the ends of each deck insert disposed in the C-shaped channels. And each of the plurality of deck inserts is removable from the C-shaped channels when the deck insert is positioned in alignment with the channel opening and the flange panel is disconnected from the frame.

  • Patent number: 7934700
    Abstract: A net/fence includes retro-reflective elements such as tapes that extend in horizontal and/or vertical directions with respect to the fence. The tapes are attached to the netting by thread or glue. One method for weaving the net/fence includes dragging the tape extending in a machine direction along the netting during weaving and threading the tape thereto. Another method for weaving the net/fence includes dragging the tape extending in a transverse direction and attaching the tape thereto with glue. A net-weaving machine can produce such a net in a machine direction and use a comb having threading needles to selectively attach the tape to the net with the thread. If attached in the transverse direction, a trolley borne on a beam lying in the transverse direction introduces the tape onto the net and a connection device, such as a glue jet, connects the tape to the net.

  • Patent number: 5957434
    Abstract: An electric fence has a series of posts connected by an elastically-stretchable, electrically-conductive string to form an enclosure for animals. The string has a unique structure which is comprised of electrically conductive and electrically nonconductive threads intertwined around a rubber core material. The threads are braided in such a way that the string may be substantially stretched without the braided threads severing. The elastically-stretchable construction prevents the string from breaking when moving animals collide with the electrified string.

  • Patent number: 5788223
    Abstract: An improved animal barrier material and an improved fastening system to simplify its knotting process are disclosed. The animal barrier material comprises a see-through cable netting characterized by strong and secure knots. An improved fastening system may be employed to simplify knotting and produce superior cable connections. The improved fastening system requires only a single spool of cable to form grids for netting; its simplified knotting process does not require passing a spool of cable through any previously-tied portion of the net. The resulting cable netting provides a superior see-through netting for simultaneous containment and visual enjoyment of zoo animals.

  • Patent number: 5699997
    Abstract: A connection device for a playyard consists of a handle and two connectors. The handle is provided integrally with a block and a plurality of protrusions having a hole therein. A pair of connectors is each provided with a plurality of spaces for receiving supports and a projecting portion having a pin stably secured therein or pivotally connected with the protrusion. When the handle is connected with the connectors by a fastener, and a holding portion is in horizontal position, the connectors are not able to be folded because of the restriction of the block within two stops of the connectors, and when the holding portion is in vertical position, two connectors are able to be folded together.

  • Patent number: 5660377
    Abstract: A self-tensioning fencing system includes a tensioner bar which is mounted directly to a structural support such as a fence post using standard nails, screws or bolts as required according to the type of a particular fence post. The tensioner bar includes a projection for pressing plastic fencing material into a recess in the fence post to allow the plastic fencing material to be tensioned across the structural support posts. A trim cap extrusion is shaped complementary to a side of the tensioner bar, opposite to the projection for engaging with the fencing material, so as to engage and cover the tensioner bar. A post cap covers the upper end of the fence post, tensioner bar and trim cap extrusion.

  • Patent number: 5575458
    Abstract: An improved mesh structure and method of making same uses a border to define the a general mesh shape and a first and a second plurality of a lengths of strand doubled back upon themselves so as to connect with the border member at points where each strand doubles back which results in an overall reduction of material of the mesh. The method of fabricating the mesh structure includes providing an alignment means to cause the first and second plurality of a lengths of cable to be doubled back upon themselves so as to create an intermediate length and two longitudinal lengths spaced apart from one another by the length of the intermediate length which pierce the border member at point corresponding to the length of the intermediate length of the doubled back strands.

  • Patent number: 5553648
    Abstract: A portable wall component is disclosed. The wall component comprises a pair of vertical posts. Each post has an upper component and a lower component with a hollow aperture extending therethrough. Each post also has a downwardly extending smaller cylindrical section at the bottom of the upper component and a complimentary cylindrical recess at the top of the lower post for receiving the smaller cylindrical section. An elastic band is located within each aperture extending along the length thereon and slightly beyond. A ring at the upper end of each upper component is coupled to the upper end of its associated band. A base component at the lower end of each lower component is coupled to the lower end of its associated band. A flexible sheet is provided with parallel upper and lower horizontal edges and parallel vertical end edges therebetween coupled to the posts. The flexible sheet has half-moon wind flaps cut therein and openings at the regions where the upper and lower components join.

  • Patent number: 5533715
    Abstract: A safety barrier for railing systems for preventing entrapment, serious injury or death resulting from bodily penetration through the baluster support members of a railing system. The barrier substantially covers the horizontal space between vertical support members and the vertical space equal to the height of the balusters by weaving a mesh scrim or web of poly-vinyl-chloride in primary form plasticized between and along the balusters resulting in taut coverage of the open spacing. A border fabricated of reinforced nylon, canvas or like material is joined to each end of the barrier, having a plurality of openings to allow a means for tightly securing the barrier to an end wall, post or any combination thereof. The barrier is adaptable to lesser dimensions in terms of length and height.

  • Patent number: 5465941
    Abstract: A fence slat locking system includes elongated plastic slats weaved between consecutive links in a chain link fence. Each slat has a wall that is curved at the lateral sides. The bottom end of the slat is notched on opposite lateral sides defining a set of slat ears. A rail is weaved horizontally between the links of the chain link fence and attached with the bottom end of each slat. By inserting the bottom end of the slat vertically downward into a rail slot, the slat ears start to flatten moving the curved tips laterally away from the central longitudinal axis of the slat. Inserting the slat further vertically downward into the rail channel allow the slat ears to snap back into their original curved cross-sectional profile allowing the curved tips of the slat ears to snap back underneath a retaining section in the rail. The "snap back" action automatically locks the fence slat into the rail.
