Modular double adjustable chock

摘要

An adjustable chock (100) of a modular design comprises a first element (102), a second element (108), a center element (104), and a center stud (106). In operational use of the chock, the first element engages with a piece of machinery (101) and the second element engages with a support (103). The first element (102) and the center element (106) have complementarily shaped contact surfaces to allow for lateral adjustment of the first element relative to the second element. The center stud (106) is connected to the center element (104) through a screwed connection. The center stud (106) is connected to the second element (108) through another screwed connection. The modular design allows using the same first element (102), the same second element (108) and the same center element (104) with center studs of different lengths.

1. An apparatus configured for use as an adjustable chock for connecting a piece of machinery to a support along a common axis of the adjustable chock, the apparatus comprising:
a first element, a second element, a center element disposed on the first element and a center stud moveably engaged with the center element; wherein
the first element has a first surface which contacts the center element and that is rotationally symmetrical and that is one of convex and concave; whereinthe first surface has a first axis of rotational symmetry substantially aligned with the common axis of the adjustable chock in operational use of the adjustable chock; whereinthe center element has an intermediate surface which contacts the first element and that is rotationally symmetrical and that is the other one of convex and concave with respect to the first surface; whereinthe intermediate surface has a center axis of rotational symmetry substantially aligned with the common axis of the adjustable chock in operational use of the adjustable chock; whereinthe first surface and the intermediate surface are complementarily shaped for engaging in operational use of the adjustable chock, only the intermediate surface of the center element contacts the first element, the intermediate surface overlying the first surface such that there is only abutting contact between the first element and the center element and the first element cannot prevent the center element from moving away therefrom; whereinthe center element has a center through-hole that is cylindrical and that is coaxial with the intermediate surface; whereina wall of the center through-hole is provided with an inner screw thread; whereinthe center stud comprises a cylindrical outer surface; whereinthe cylindrical outer surface has a stud axis of rotational symmetry that is substantially aligned with the common axis of the adjustable chock in operational use of the adjustable chock; whereinthe cylindrical outer surface is provided with an outer screw thread for engaging with the inner screw thread of the center element so as to have the center stud and the center element connected through a screwed connection in operational use of the adjustable chock, the cylindrical outer surface has a constant diameter that corresponds to a maximum diameter of the center stud such that the center stud does not have any piece integral with it that has a larger diameter than the cylindrical outer surface; whereinthe center stud comprises a stud through-hole that is cylindrical, that extends across a full length of the center stud and that is coaxial with the cylindrical outer surface, and wherein the second element includes a cylindrical recess with a second inner screw thread for engaging with the outer screw thread of the center stud so as to have the center stud and the second element connected through a further screwed connection in operational use of the adjustable chock.
