Abstract
The present portable fence is durable, lightweight and easily transported, erected and dismantled. In use, it will collapse upon impact, due to a break away, in the first embodiment, a joint between the fence post and its supporting leg, and in the second embodiment a joint in the supporting leg, yet in both embodiments the fence may be quickly and easily re-erected.
Claims17
A portable fence comprising:
- a frame,
- a panel of netting,
- means supporting the netting within the frame, the frame defining a section of fence, the frame including at least one upright member for supporting the frame in a generally vertical orientation relative to a field,
- a foot member,
- means attaching the foot member to the upright member in a generally orthogonal orientation so that the foot member may rest on the field and assist in holding the frame in a vertical orientation, the attachment means releasing the foot member from its orthogonal relationship to the upright member on applications of a predetermined force to the fence to permit the fence to collapse to the field, the attachment means reconnecting the foot member to the upright member in an orthogonal relationship when the frame is returned to its generally vertical orientation relative to the field;
- and wherein the frame is defined by peripheral tubular members, the peripheral tubular members each including a longitudinal slot for receiving a margin of the netting panel, said supporting means including a plurality of wedge elements for being received-within the marginal spaces of the net and the longitudinal slot of a tubular member to interlock the netting with the tubular members.

A portable fence comprising:
- a frame,
- a panel of netting,
- means supporting the netting within the frame, the frame defining a section of fence, the frame including at least one upright member for supporting the frame in a generally vertical orientation relative to a field,
- a foot member,
- means attaching the foot member to the upright member in a generally orthogonal orientation so that the foot member may rest on the field and assist in holding the frame in a vertical orientation, the attachment means releasing the foot member from its orthogonal relationship to the upright member on applications of a predetermined force to the fence to permit the fence to collapse to the field, the attachment means reconnecting the foot member to the upright member in an orthogonal relationship when the frame is returned to its generally vertical orientation relative to the field;
- and wherein said attachment means connecting said foot member to said corresponding upright member includes a plug element attached to one of the members and snugly interfitting with the end section of the attached member, and extendable means holding the plug to said attached member but permitting the plug and end section to separate on application of said predetermined force to the fence to permit the foot member to pivot relative to the frame.

A Collapsible portable fence section comprising:
- a peripheral member defining a portion of the fence section,
- a base member engaged with said peripheral member of said fence section for supporting said fence in a vertical position on a field;
- collapsible means connecting/said peripheral member with said base member of said fence section for permitting said fence section to collapse from said vertical position to a horizontal position lying flat on said field when a predetermined force is applied to said fence;
- means received within said peripheral member for mechanically repositioning said fence section into said vertical position whenever said fence section has been collapsed to said horizontal position
- a hollow tube attached to said peripheral member and having at least one outlet extending therefrom;
- at least one base tube;
- at least one base connector having a plurality of hollow base outlets, a first of said base outlets being positioned perpendicular to a second base outlet, said first base outlet receiving and connected to said base tube;
- a base plug having a circumference that permits it to be snugly received into said hollow tube outlet and said second base outlet;
- plug-fixing means for fixing said base plug to one of said outlets which receive it;
- whereby said base tube can pivot to any angle in the plate perpendicular to said hollow tube when said base plug is inserted into said hollow tube outlet.

A collapsible portable fence section comprising:
- a peripheral member defining a portion of the fence section,
- a base member engaged with said peripheral member of said fence section for supporting said fence in a vertical position on a field;
- collapsible means connecting said peripheral member with said base member of said fence section for permitting said fence section to collapse from said vertical position to a horizontal position lying flat on said field when a predetermined force is applied to said fence;
- means received within said peripheral member for mechanically positioning said fence section into said vertical position whenever said fence section has been collapsed to said horizontal position;
- a resilient elastic element;
- means fixing one end of said element within said peripheral member while said element is stretched,
- whereby said elastic element urges said base member and peripheral member into engagement with one another.

A collapsible portable fence section comprising:
- a peripheral member defining a portion of the fence section,
- a base member engaged with said peripheral member of said fence section for supporting said fence in a vertical position on a field;
- collapsible means connecting said peripheral member with said base member of said fence section for permitting said fence section to collapse from said vertical position to a horizontal position lying flat on said field when a predetermined force is applied to said fence;
- and
- means received within said peripheral member for mechanically repositioning said fence section into said vertical position whenever said fence section has been collapsed to said horizontal position;
- each said fence section further comprising:
- a plurality of peripheral members to define a rectangular frame;
- a rectangular net being substantially the same size as said rectangular frame and positioned within said rectangular frame;
- net securing means securing said net within said frame and to said peripheral members whereby said net prevents objects from passing through said frame;
- a plurality of wedges, each being attached to an edge point of said net;
- flanges fixed to said peripheral members and extending inward within said frame and toward one another;
- each of said flanges having an opening shaped for closely receiving said wedges and for permitting said wedges to slide along the length of said flange but for preventing said wedges and the attached net from being pulled from the frame in a direction generally perpendicular to said peripheral members.

A portable fence section comprising:
- a panel of netting;
- frame means for supporting said panel of netting;
- a foot means for supporting said frame means;
- support means, connecting said foot means to said frame means, to enable adjustment of said foot means, said Support means, frame means and panel of netting forming a upright section;
- collapse means attached to said foot member for carrying said upright section in an upright orthogonal orientation when said foot member rests on a horizontal surface and for releasing said upright section to permit said upright section to collapse to said horizontal surface upon application of a predetermined force to said upright section, and for said upright section to be again carried in a vertical position when said upright section is returned to its generally vertical orientation relative to the horizontal surface;
- and
- attachment means on said upright section to permit one portable fence section to be interconnected to another fence section.
