JPS586111B2 - Foldable support for tripods, lighting equipment legs, etc. - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel foldable support for camera tripods, lighting equipment legs, etc. that can be folded while placed on the floor. Casters that can change direction are attached to the outer ends of the horizontal leg columns, and three-split heads are attached to the inner ends of the horizontal leg columns, and the heads of these horizontal leg columns are mutually rotatable only in the horizontal direction using shaft pins. The legs are connected in such a way that when the head body is oriented in the centripetal direction, the leg rods are parallel to each other in the three radial directions, and when the head body is oriented in the same direction, they are parallel to each other, and they are mutually engaged with the head bodies at both ends. A locking device was installed to keep the camera facing in the centripetal direction, and each leg rod was equipped with a catch device for tripod legs, lighting equipment legs, etc. via a slider so that it could slide freely along the leg rod. The gist of this is that

To explain an embodiment of the present invention with reference to the drawings, three horizontal leg rods 1, 1', 1'' are constructed, and the outer ends of each horizontal leg rod 1, 1', 1'' are Casters 2, 2', 2'' with a stopper that can change direction freely are attached to the lower surface, and three-split head bodies 3, 3', 3'' are attached to the inner end, respectively, and each head body 3, 3', Horizontal circular support walls 4, 4', 4'' that interlock with each other are provided on the shoulders of 3'', and the circular support walls 4, 4', 4''
By inserting the shaft pins 5, 5' vertically into each horizontal leg rod 1
, 1', 1'' head bodies 3, 3', 3'' are connected to each other so that they can rotate horizontally, and when the head bodies 3, 3', 3'' are directed in the centripetal direction, the leg rod 1 . A locking device 9 is provided which returns by a spring 8 and engages with the hole 7 to maintain the head body 3, 3', 3'' facing in the centripetal direction when the lever 6 is released. Slider 10.10' Each leg rod 1, 1', 1'' is provided with a fixing screw 14 that slides along the same leg rod 1, 1', 1''.
,10'', and this slider 10.10',10
A pipe 1 that is equipped with a catch device 11, 11', 11'' such as a tripod leg or a lighting equipment leg on the top surface, and a support or pedestal etc. is installed at the tip of the central head body 3'.
2 is fixed with screws 13.

Since the present invention is constructed as described above, the leg rods are expanded radially in three directions as shown by the solid lines in Figure 1, and the catch device equipped on the leg rods is used to attach camera tripods and lighting equipment. This device is used to secure camera tripods and lighting equipment on the leg levers by holding the lower ends of the legs, etc., but the present invention is particularly designed to attach a directional screw to the outer end of each of the three horizontal leg levers. Three split-shaped heads are attached to the inner ends of convertible casters, and the heads of these horizontal leg rods are connected to each other by shaft pins so that they can rotate only in the horizontal direction, and the heads are centripetal. When facing in the same direction, the leg rods are parallel to the three radial directions, and when facing in the same direction, they are parallel to each other, so when not in use, the leg rods can be closed and converged in a parallel state as shown by the phantom lines in Figure 1. Not only is it convenient to store and carry, but the operation is extremely simple as the leg levers can be opened and closed by rolling the casters on the bottom of the leg levers while they are on the floor. In addition, locking devices are provided that engage the heads of the leg rods at both ends to maintain the heads facing in the centripetal direction, so when the leg rods are expanded radially in the three directions mentioned above, these locking devices are used. It has the advantage of being able to firmly maintain the expanded state with the stopper, and since the catch device is attached to the leg lever via a slider that is slidable along the leg lever, the slider can be moved as necessary. The catch device can be positioned at any location on the leg rod, which is extremely convenient.
