Abstract
To create a stable and safe frame, more particularly in the form of a tripod, having a plurality of rod-like legs (2), which are fastened centrally to a connection part (3), wherein the frame (1) can be folded up into a space-saving transportation position, in which the legs are oriented substantially in parallel, and the frame can be folded out into a usage position, in which the legs are crossed, the invention proposes that at least one concavely rounded support surface (5) for providing support over an area of the leg surface is arranged between the legs (2), more particularly that two support surfaces (5, 5′) of this type are provided, which in the usage position are in contact with an area of the respective leg surface opposite one another.
Claims19
A frame, having a plurality of elongated legs which are fastened centrally to a connection part, each leg having an exterior leg surface, wherein the frame can be folded into a space-saving transport position in which the legs are aligned generally parallel to one another, and the frame can be unfolded into a usage position in which the legs overlap one another at the connection part,
- the connection part includes at least one concavely rounded support surface for each leg for providing surface support, each concavely rounded support surface being in direct surface contact with a leg surface only in the usage position and spaced apart from the associated leg surface when the frame is in the space-saving transport position, and wherein the concavely rounded support surface of the connection part is disposed between two of the plurality of legs,
- wherein a pin for each leg is between two concavely rounded support surfaces, each pin extends outwards from the connection part, wherein the associated leg of a pin can rotate around the pin.
A frame assembly for supporting an article in an elevated condition, said assembly comprising:
- first and second and third legs, each of the first and second and third legs being of an elongated construction and extending between opposite ends, each of the first and second and third legs having a generally equal length,
- a connection part pivotally attached to each of the first and second and third legs generally centrally along the respective lengths thereof and wherein the connection part is located between the legs, the connection part configured to enable articulating movement of each leg between a space-saving transport position in which the first and second and third legs are aligned largely parallel and a usage position in which the first and second and third legs are splayed in a crossed manner with the respective ends thereof spread apart from one another, the plurality of legs overlapping one another at the connection part when in the usage position,
- the connection part including at least two concavely rounded support surfaces associated with a respective one of the legs, the at least two concavely rounded support surfaces arranged to provide surface support for the associated leg in the usage position, and wherein the concavely rounded support surfaces are disposed between the plurality of legs at the connection part,
- wherein each leg is a hollow tubular member, further including a stiffening insert disposed inside each of the first and second and third legs, each stiffening member traversing the connection part to reinforce the leg directly adjacent the connection part.
A frame assembly for supporting an article in an elevated condition, said assembly comprising:
- first and second and third legs, each of the first and second and third legs being of an elongated construction and extending between opposite ends, each of the first and second and third legs having a generally equal length,
- a connection part pivotally attached to each of the first and second and third legs centrally along the respective lengths thereof and wherein the connection part is located between the legs, the connection part configured to enable articulating movement of each leg between a space-saving transport position in which the first and second and third legs are aligned largely parallel and a usage position in which the first and second and third legs are splayed in a crossed manner with the respective ends thereof spread apart from one another, the plurality of legs overlapping one another at the connection part when in the usage position,
- the connection part including at least two concavely rounded support surfaces associated with a respective one of the legs, the at least two concavely rounded support surfaces arranged to provide surface support for the associated leg in the usage position, and wherein the concavely rounded support surfaces are disposed between the plurality of legs at connection part,
- wherein each concavely rounded support surfaces includes a latching lug, each latching lug being aligned parallel to its associated leg in either the transport position or the usage position.
A tripod frame assembly for supporting an article in an elevated condition, said assembly comprising:
- first and second and third legs, each of the first and second and third legs being of an elongated construction and extending between opposite ends, each of the first and second and third legs having a length, the lengths being generally equal,
- a connection part pivotally attached to each of the first and second and third legs generally centrally along the length thereof and wherein the connection part is within the legs, the connection part configured to enable articulating movement of each leg between a space-saving transport position in which the first and second and third legs are aligned largely parallel and a usage position in which the first and second and third legs are splayed in a crossed manner with the ends thereof spread apart,
- the connection part including at least three pairs of concavely rounded support surfaces, one pair of concavely rounded support surfaces associated with each of the first and second and third legs, each pair of concavely rounded support surfaces arranged to provide surface support for a respective one of the first and second and third legs in the usage position, each pair of concavely rounded support surfaces including a gusset-shaped latching lug, each latching lug being aligned parallel to its associated leg in either the transport position or the usage position, the connection part including three circumferentially spaced pins, each pin pivotally joining the connection part to a respective leg, a fastener interacting with each pin to secure the associated leg thereto, a biasing element operatively disposed between each fastener and each pin.
