Abstract

Weight stack selection system for fitness equipment. Central stem having offset lateral movement is eliminated by present invention. The select pin is easier for insertion to the selected desired weight due to the lack of accumulated thickness the plagued the industry. And an intuitive Auto-Off selection box is also added to make the equipment more user-friendly, allowing user to simply pushed in the desired weight for training.

Claims

1. Weight stack selection system for fitness equipment, comprising:

a. A plurality of link-connectors that can be connected vertically;

b. A plurality of weight plates where each weight plate further having a vertical center hole for engageably receiving one link-connector; and

,

c. A select pin that can be slidably fitted through the side of one weight plate to one link-connector, whereby a set number of weight plates above the point of said select pin is selected when said select pin is inserted through said weight plate and link-connector.

2. Weight stack selection system for fitness equipment, comprising:

a. A plurality of link-connectors that can be connected vertically;

b. A plurality of weight plates where each weight plate further having a vertical center hole for engageably receiving one link-connector;

c. A plurality of link pins where each pin can be slidably fitted through the side of one weight plate to one link-connector to form a stack of selected plates above the point of said link pin; and

,

d. Means for user selection of one link pin in said selection system when multiple weight plates are vertically stacked together along with respective link-connectors fitted into the weight plates.

3. The selection system of claim 2, wherein the means for user selection of one link pin to achieve selection of desired weight is a lever design wherein a select pin parallel to the link pin is used and connected to said link pin by a lever pivoting at mid point of said lever, to create reverse travel of the link pin relative to the movement of said select pin.

4. The selection system of claim 2, wherein the means for user selection of one link pin to achieve selection of desired weight is by an on-off toggle control, wherein a select pin parallel to the link pin is used and connected to said link pin by a centrally located gear wheel that creates a reverse travel of the link pin relative to the movement of said select pin, and further having a on-off toggle control switch on the select pin.

5. The selection system of claim 3, wherein the means for user selection of one link pin to achieve selection of desired weight further having an auto-off selection box comprising:

i. a case with a plurality of short slots and long slots on the front and back sides, respectively, of said case;

ii. a long plate having the same number of long slots matching the long slots on said case;

iii. a plurality of wedges for insertion in and through said long and short slots;

iv. a pull spring connecting said case with said long plate; and

,

v. a plurality of push spring at tip of each wedge producing pushing out force when the long slots are open.

6. The selection system of claim 4, wherein the means for user selection of one link pin to achieve selection of desired weight further having an auto-off selection box comprising:

i. a case with a plurality of short slots and long slots on the front and back sides, respectively, of said case;

ii. a long plate having the same number of long slots matching the long slots on said case;

iii. a plurality of wedges for insertion in and through said long and short slots;

iv. a pull spring connecting said case with said long plate; and

,

v. a plurality of push spring at tip of each wedge producing pushing out force when the long slots are open.
