This invention relates to a tripod for cameras, which is capable of regulating an angle at which the leg units thereof are opened, to thereby allow an object to be photographed at a low angle, and which consists of a tripod head, leg units each of which is oscillatably supported on the tripod head and each of which has projections at that end portion thereof which is above the oscillatably supported portion thereof, and regulators each of which is supported on a shaft in such a manner that the regulator is urged in a direction at right angles to the relative leg unit and each of which has alternately-arranged projections and recesses in that position thereon which is on the side of the tripod head and in opposition to the projections provided on the leg units coming into contact, when the leg units are opened in the usual condition, with the projections provided on the regulators, to thereby allow the leg units to be set at the most-frequently-used leg-opening angle, the projections provided on the relative leg unit, the projections provided on the leg units coming into engagement, when the leg units are opened after the regulators have been displaced in the direction at right angles to the leg units against the urging forces applied thereto, with the recesses provided in the regulators, to thereby allow the leg units to be set at an increased leg-opening angle, the regulators which have been displaced in the mentioned manner being returned to their respective original positions when the leg units are thereafter closed.

A tripod for cameras, comprising in combination: (a) a tripod head (1) with sides and a lower portion, support walls (1a, 1b) at said lower portion; (b) elongated leg units (2), said leg units being pivotally supported on said tripod head (1), said leg units (2) having an upper portion and an outer

A tripod for cameras, comprising in combination: (a) a tripod head (1) with sides and a lower portion, support walls (1a, 1b) at said lower portion; (b) elongated leg units (2), said leg units being pivotally supported on said tripod head (1), said leg units (2) having an upper portion and an outer end above said upper portion, pivot means (3) at said upper portion for pivoting said leg units; (c) projections (10a, 10b) at said outer ends; (d) a support shaft (11) supported by said support walls (1a, 1b) for each leg unit; (e) regulators (12) for each leg unit with spring means (16), each of which is supported on said shaft (11) in such a manner that the regulator (12) is urged in a direction at right angles to the corresponding elongated leg unit (2); and, (f) alternately-arranged projecting means (12a, 12a) and recesses (12b, 12b) on each regulator, disposed on one side of said tripod head (1) and opposite said projections (10a, 10a) so that said projections come into contact with said regulators when said leg units (2) are opened in the usual condition, to thereby allow said leg units to be set at the most-frequently-used leg-opening angle, said projections (10a, 10a) provided on the leg units comming into engagement, when said regulators have been displaced in the direction at right angles to the leg units (2) against the spring means forces applied thereto, to allow the leg units (2) to be set at an increased leg-opening angle, said regulators (12) which have been displaced in the manner mentioned being returned to their original position when the leg units (2) are thereafter closed.
