Abstract: A telescoping device including an upper tubular body, a lower tubular body, and a fixing unit that releasably fixes the lower tubular body with respect to the upper tubular body. The fixing unit includes an operation body and a fixation body. The fixation body consists of an outer member, an upper inner member, and a lower inner member. On the outer member, inner peripheral upward inclined surfaces and inner peripheral downward inclined surfaces are formed. On the upper inner member, outer peripheral downward inclined surfaces are formed, and on the lower inner member, outer peripheral upward inclined surfaces are formed.

Abstract: A telescoping device capable of preventing a lower tubular body from jouncing during fixation by a fixing unit includes a leg body being a telescoping device includes an upper tubular body, a lower tubular body, and a fixing unit that releasably fixes the lower tubular body with respect to the upper tubular body. The fixing unit includes an operation body and a fixation body. The fixation body consists of an outer member, an upper inner member, and a lower inner member. On the outer member, inner peripheral upward inclined surfaces and inner peripheral downward inclined surfaces are formed. On the upper inner member, outer peripheral downward inclined surfaces are formed, and on the lower inner member, outer peripheral upward inclined surfaces are formed.

Abstract: This invention relates to a support device with which it is possible to use a supported object stably. A support device is provided with a base body mounted to a leg device. An inclination portion of the base body is mounted with a base end portion of a first turning body and a base end portion of a second turning body so as to be turnable. A tip portion of the first turning body and a tip portion of the second turning body are mounted with a support body so as to be turnable. Both the turning bodies turn upward with respect to the base body so that the support body turns 90 degrees to be in a lengthways state. Both the turning bodies turn downward with respect to the base body so that the support body turns 90 degrees to be in a sideways state.

Abstract: A support device for a tripod includes a base body. On the base body, a pan turning body is provided turnably in the horizontal direction. On the pan turning body, a tilt turning body is provided turnably in the up-down direction. The support device also includes a pan fixing operation body fixing the pan turning body with respect to the base body, and a tilt fixing operation body fixing the tilt turning body with respect to the pan turning body. The support device further includes a tilt turning operation body turning the tilt turning body with respect to the pan turning body.

Abstract: A leg device that is capable of simultaneously releasing three extendible/contractible legs from a locked state with a single action is provided. A tripod, which is a leg device, has a base. A tripod head is attached to a tripod head attaching portion of the base. A middle extendible/contractible leg, a one-side extendible/contractible leg, and an opposite-side extendible/contractible kg are pivotally attached to a leg attaching portion of the base. Gripping all the three extendible/contractible legs, i.e. the middle extendible/contractible leg, the one-side extendible/contractible leg, and the opposite-side extendible/contractible kg, together causes the middle extendible/contractible leg, the one-side extendible/contractible leg, and the opposite-side extendible/contractible leg to simultaneously shift from a locked state to an unlocked state.

Abstract: The leg device includes a base portion, extendable legs rotatable with respect to the base portion, and leg support members for rotatably supporting the extendable legs, wherein the extendable leg includes the first tubular member having a fitting hole portion formed in the vicinity of the upper end thereof. The second tubular member that is adjustable with respect to its protruding length from the lower end of the first tubular member is inserted into the first tubular member. The leg support member includes a pivot portion rotatably fitted in the fitting hole portion. In a state where the extendable leg is contracted, the upper end of the second tubular member is positioned upward of the pivot portion.
