The present disclosure relates to a tripod comprising a connecting element, at least three legs coupled to said connecting element, each leg being divided into at least two sections able to slide with respect to each other. Each leg provides locking and unlocking means of the sliding movement between the sections of the respective leg. Said tripod further provides an actuation element of said locking and unlocking means. Said tripod is characterized in that said actuation element is arranged on said connecting element, and in comprising transmission means arranged on the connecting element connected to said actuation element and to said locking/unlocking means of each leg and in that said tripod is configured so that by acting on said actuation element said transmission means act simultaneously on said locking/unlocking means of each leg preventing/allowing the sliding movement between said sections of each leg.

This invention relates to a tripod for shooting equipment that will find application both in the shooting industry and for personal purposes, and in particular for the installation of video or photographic equipment, a camera or other optical instrument. The tripod (1) has three adjacent telescopic legs (3) with identical locking mechanisms connected to the handle (5) located above the central support element (2). The handle (5) actuates the locking mechanisms simultaneously and independently of one another, whereby the legs (3) can be telescopically adjusted from the free state to the locked position in the desired position when unfolding or folding the tripod (1). Locking mechanisms provide stability when loading the tripod (1). The telescopic legs (3) of the tripod (1) are pivotally connected to the central support element (2), so the different angles of the legs (3) do not affect the effective operation of the locking mechanisms.

The present invention discloses a telescopic rod connector, which includes an outer sleeve, an inner sleeve and a screw rod. The screw rod has opposite a first end and a second end, and a rod body between them. The inner sleeve sleeves on the rod body and can rotate and slide along it, and the inner sleeve is provided with positioning convex strips. The outer sleeve includes a notch ring and a plurality of outer arc members extending from the notch ring. U-shaped notches are arranged between adjacent two the outer arc members; the outer sleeve is arranged on the outside of the inner sleeve and the notch ring is close to the first end, and the positioning convex strips are inserted into the U-shaped notches. The outer sleeve is rotated to drive the inner sleeve to slide along the rod body.

A lift buffering structure includes a hollow column-shaped housing, a holding seat fixedly connected to an inner wall surface of the hollow column-shaped housing, an inner stem disposed in the hollow column-shaped housing and slidably extended through the holding seat, an elastic element having an end connected to the inner stem and another end to the holding seat to limit a travel stroke of the inner stem, an abutting unit disposed at one side of the holding seat opposite to the elastic element and having a width downward reduced gradually along a height direction of the hollow column-shaped housing, and an anti-slip unit connected to a lower end of the inner stem and located between the abutting unit and the inner wall surface of the hollow column-shaped housing. The lift buffering structure having the above structure can overcome a lot of problems in the conventional gas and oil struts.

Disclosed is a height adjustable stand for supporting an object, such as a table leaf or a camera. The invention also relates to a table including the stand. The stand includes at least a first leg, at least a first locking device and at least a first central operating device including at least a first elongated operating element that is arranged to allow the first locking device to be transferred from a locked resting state to an unlocked state in which the height of the stand is adjustable. The construction of the stand is lean and robust allowing height adjustment and stable positioning of the stand and thereby the table, even on uneven supporting surfaces simultaneously. User comfort is improved as precious time can be saved especially when installing multiple stands or tables.

There is provided a lock mechanism for an adjustable rod. The lock mechanism provides a manually locking state and an automatic locking state. The automatic locking state provides a more secure locking engagement than the manual locking state. There is also provided improved end cap systems that minimize the number of components.

A device for locking a rod member is provided. The device includes a body section having a vertical hole therein, and a ring-type locking unit and a piston serially arranged along the hole, wherein the rod member is disposed in the hole to be axially movable through the locking unit and the piston. The locking unit may be a lock block including an outer ring having an inclined surface on one side thereof, thereby defining a wedge-type space, an inner ring coaxially disposed in one side of the outer ring and accommodating a pressurizing member interacting with the inclined surface, and a spring disposed in the other side of the outer ring so as to elastically connect the outer ring and the inner ring.

Length-adjustable strut assemblies for external fixation systems, and corresponding external fixation systems, are disclosed. The strut assemblies include an elongate first and second end members, an elongate intermediate member, and first and second adjustment mechanisms. The intermediate member comprises a threaded rod fixedly coupled within an axial cavity thereof, and is rotatably fixed and axially translatably within an axial cavity of the first end member. An end portion of the second end member is received within the axial cavity of the intermediate member, and the second end member comprises an axial cavity threadably coupled with the threaded rod. The first adjustment mechanism is configured to selectively axially fix the intermediate member relative to the first end member. The second adjustment mechanism is configured to selectively rotate the second end member with respect to the threaded rod to axially translate the second end member relative to the intermediate member.
