KNUCKLE BRACKET

Abstract

A knuckle bracket (1) for a cylinder (20) comprises outer and inner brackets (2, 10). The outer bracket (2) comprises a pair of outer plates (4, 5) projecting in a lateral direction with respect to a cylinder axis. The inner bracket (10) comprises a pair of inner plates (12, 13) overlap the outer plates (4, 5) on the inner side thereof. A guide (17) of having outwardly curved shape is formed on a leading edge (X, Y) of each of the inner plates (12, 13) so as to facilitate introduction of a connecting part (90) of a knuckle bracket (N) into the inner bracket (10). By forming a notch (7) on a leading edge of each of the outer plates (4, 5) to accommodate the guide (17), the size of the knuckle bracket (1) can be suppressed.

Claims

1. A knuckle bracket adapted to be fixed to a cylinder for connecting a knuckle spindle to the cylinder, the knuckle spindle having a connecting part fixed to the knuckle bracket, comprising: a pair of outer plates disposed in parallel with each other and projecting in a lateral direction with respect to an axis of the cylinder;a pair of inner plates overlapping the outer plates on the inner side thereof, a space between the pair of inner plates being used for accommodating the connecting paw; anda guide formed on a leading edge of each of the inner plates having an outwardly curved shape for introducing the connecting part into the space between the pair of inner plates;wherein, each of the pair of outer plates comprises a notch in a position corresponding to the guide to accommodate the guide.

2. The knuckle bracket as defined in claim 1, wherein each of the inner plates comprises a pair of notches formed on both sides of the guide.

3. The knuckle bracket as defined in claim 1, wherein the guide comprises a tip projecting beyond the leading edge of each of the inner plates in a direction leading away from the cylinder.

4. The knuckle bracket as defined in claim 3, wherein the tip of the guide projects beyond the leading edge of each of the outer plates in the direction leading away from the cylinder, and a distance from the leading edge of each of the outer plates to the tip of the guide is set within one millimeter.

5. The knuckle bracket as defined in claim 1, wherein the guide is formed in an inverted trapezoidal shape.

6. The knuckle bracket as defined in claim 1, wherein the pair of outer plates and the pair of inner plates respectively have bolt holes in locations corresponding to through-holes of the connecting part and the connecting part is fixed to the knuckle bracket by bolts passed through the bolt holes and the through-holes.

7. The knuckle bracket as defined in claim 1, wherein the pair of outer plates are formed as a part of an outer bracket which comprises a main part having an arc shape so as to be in contact with the cylinder, the pair of outer plates projecting from both ends of the main part, and the pair of inner plates are formed as a part of an inner bracket which comprises a main part having an arc shape so as to be in contact with the cylinder, the pair of inner plates projecting from both ends of the main part of the inner bracket.
