Abstract

The technology disclosed provides a joint for connecting carrier units together so as to dissipate and absorb axial forces experienced by the carrier units. The joint may be comprised of a joint housing and an elastomeric insert. The housing may be comprised of a body portion and a head portion and the head portion may include an annular flange in which the elastomeric insert is configured to be secured. The elastomeric joint is capable of absorbing and dissipating horizontal, rotational, and vertical forces experienced by the carrier units in non-linear travel along a track.

First claim

What is claimed is:

1. A method of dissipating forces between carrier units, the method comprising:
connecting a first carrier unit to a second carrier unit using an elastomeric joint, wherein the elastomeric joint comprises a joint housing and an elastomeric insert disposed within a bore in the joint housing;
wherein the elastomeric insert comprises:
an outer ring;
an inner ring disposed concentrically within the outer ring, the inner ring connected to at least a portion of the outer ring by one or more supports, a front gap and rear gap being formed between the inner ring and the outer ring; and
a bumper disposed in the front gap, the bumper connected to a portion of the inner ring;

receiving a force on the carrier units; and
dissipating the force in the elastomeric joint.

2. The method of claim 1 , wherein the step of connecting the first carrier unit to the second carrier unit further comprises:
connecting a first post on the first carrier to an annular flange on the elastomeric joint; and
connecting a second post on the second carrier to a longitudinal bore in the elastomeric joint.

3. The method of claim 2 , wherein the step of dissipating the force in the elastomeric joint further comprises receiving the force experienced by the first carrier at the first post at the elastomeric insert.

4. The method of claim 3 , wherein the elastomeric insert is configured to dissipate the force by elastically adjusting within the joint housing and by absorbing the force.

5. The method of claim 3 , further comprising connecting a plurality of carrier units using a plurality of elastomeric joints, wherein the plurality of carrier units comprise a conveyor train.

6. The method of claim 5 , wherein the step of receiving the force is a result of the plurality of carrier units traveling in a curve.

7. The method of claim 5 , wherein the step of receiving the force is a result of the plurality of carrier units traveling on an incline.

8. The method of claim 5 , wherein the plurality of carrier units comprise a part of a conveyor system.

9. The method of claim 1 , wherein dissipating the force comprises deforming the inner ring and the supports into the front gap or the rear gap.

10. The method of claim 1 , wherein dissipating the force comprises deforming at least the inner ring into the front gap and contacting the bumper to the outer ring.

11. The method of claim 10 , wherein contacting the bumper to the outer ring comprises deforming the bumper against an inner surface of the outer ring to limit the movement of the inner ring.
