1,211,460. Tripod. MESSERSCHMITTBOLKOW-BLOHM G.m.b.H. 24 April, 1968 [25 April, 1967], No. 19387/68. Heading F3C. A tripod has three legs 14 mounted at 120- degree spacing about a training mounting 9, the mounting of the legs being identical and comprising a pin 41 carried by the mounting 9, a toothed member 37 also carried by the mounting, a toothed member 36 carried by the leg and having a bore 32 in which the pin is received, such that the teeth of the toothed members can engage, each leg mounting including means 58 to hold the teeth in engagement and means 44 to disengage the teeth to permit pivoting of the leg about the pin, the leg mountings and the legs being such that the legs can be pivoted to positions (Fig. 4, not shown) in which they all extend in substantially the same direction. Each hand operable lever 44 is pivoted at 43 to its leg and is provided with a projection, extending into the counterbore 33, comprising a spherical portion 47, a waist 48 and a conical portion 34. The spherical portion has grooves which, when the leg is turned to align them with balls 38 permit the latter to pass when the leg is attached to the base portion. To turn the leg the lever 44 is pressed, compressing the spring 58 and disengaging the teeth 36, 37 to allow the leg to be rotated about pin 41. In the extended position of the legs, projections 62 thereon abut the base member to prevent further movement. Provision of duplicate projections 62 permit interchangeability of the legs. The free end of each leg is provided with shells 20, 21 and nuts 23 in which may be screwed a projection 24. The tripod is associated with a missile launcher (4, Fig. 1, not shown) and the arrangements for mounting the launcher on the tripod are shown in that figure. |
