Series of matched sets of compatible chain-system parts
| Details |
Inventors: Rieger, Werner;
Assignee:
Primary Examiner: Di Palma; Victor A.
Assistant Examiner: Crosby; Gene P.
Attorney, Agent or Firm: Smythe & Moore
The invention relates to a series of matched sets of parts for a chain system, each set including a chain link of round-section bar, a connecting member and a lockable retainer pin for retaining the link in engagement in a slot in the connecting member. The invention provides that in order to ensure that links and connecting members which are incompatible in strength cannot be joined together, the bar diameters of the chain links, the widths of the slots in the connecting members, the internal widths of the links and the diameters of the retaining pins are varied stepwise from size to size from one matched set to the next in the series. |

DETAILED DESCRIPTION I claim: 1.
A series of matched sets of parts for a chain system comprising chain links of round-section bar and attachable connecting members for joining chains together, each connecting member having a slot to accommodate a chain link and a lockable retainer pin for retaining a chain link in said slot, wherein links and connecting members which are incompatible in strength cannot be joined together, the bar-diameters of said chain links, the widths of the slots in the connecting members, the internal widths of the links and the diameters of the retaining pins vary stepwise from size to size from one matched set to the next in the series in that the diameters of said retainer pins are each approximately 1.
2 times the bar-diameters of the compatible chain links, and the bar-diameters and the internal widths of said links increase by approximately 25% from one size link to the next larger size in the series of matched sets whereby only links and connecting members compatible in strength can be joined together.
2.
A series of matched sets as claimed in claim 1, wherein the components of the series of sets each of compatible size have the following approximate dimensions in millimeters:
Connecting
Link Bar- Member Pin Internal
Diameter Slot Width Diameter Link Width

Description
Description:
The invention relates to a series of matched sets of compatible chain-system parts comprising chain links of round-section bar and attachable connecting members, for use in suspending chains from supports, shortening the chains, joining chains together, suspending objects from the chains and attaching objects to the chains, each connecting member having a slot to accommodate a compatible chain link and a lockable retainer pin compatible with the link for retaining it in the slot
