Abstract

Mat locking pins include a pin body and a wheel housed within the pin body, the wheel configured to be movable from a first position to a second position, wherein in the first position the wheel is housed within the pin body and in the second position at least a portion of the wheel extends from the pin body. Mat systems include such mat locking pins to enable movement of the may system and/or secure two mats together.

Claims (30)

1. A mat locking pin comprising:

a pin body configured to be installed into pin apertures to secure multiple mats together; and

a wheel housed within the pin body, the wheel configured to be movable from a first position to a second position, wherein in the first position the wheel is housed within the pin body and in the second position at least a portion of the wheel extends from the pin body.

2. The mat locking pin of claim 1 , wherein the pin body is configured to be inserted into respective aligned pin apertures of a first mat and a second mat to secure the first mat to the second mat.

3. The mat locking pin of claim 1 , further comprising an actuator operably coupled to the wheel, wherein actuation of the actuator causes the wheel to move between the first position and the second position.

4. The mat locking pin of claim 3 , wherein the actuator comprises a threaded component that is rotatable to cause translation of the wheel between the first position and the second position.

5. The mat locking pin of claim 3 , wherein the actuator comprises a lever arm.

6. The mat locking pin of claim 5 , wherein the lever arm is pivotable about a pivot to cause rotation of the lever arm to be converted to translation movement of the wheel between the first position and the second position.

7. The mat locking pin of claim 3 , wherein the actuator comprises an indicator configured to indicate a position of the wheel.

8. The mat locking pin of claim 3 , wherein the actuator is at least partially housed within an actuator cavity defined within the pin body.

9. The mat locking pin of claim 8 , wherein the actuator cavity comprises a threaded portion and the actuator comprises a corresponding threaded portion that engages with the threaded portion of the actuator cavity.

10. The mat locking pin of claim 3 , further comprising a biasing member coupling the actuator to the wheel.

11. The mat locking pin of claim 1 , further comprising a rotor arranged within the pin body and configured to move from a first position to a second position of the rotor, wherein in the second position the rotor is configured to secure a first mat to a second mat.

12. The mat locking pin of claim 1 , further comprising a wheel cavity defined within the pin body, wherein the wheel is housed within the wheel cavity and movable from within the wheel cavity in the first position to at least partially extended from the wheel cavity in the second position.

13. A mat system comprising:

a first mat comprising a first lip structure having a plurality of pin apertures defined in the first lip structure;

a second mat comprising a second lip structure having a plurality of pin apertures defined in the second lip structure, wherein the first lip structure is configured to overlap the second lip structure and at least one pin aperture of the first lip structure aligns with at least one pin aperture of the second lip structure to define an aligned pin aperture; and

a wheeled pin inserted into the aligned pin aperture, wherein the wheeled pin comprises:

a pin body; and

a wheel housed within the pin body, the wheel configured to be deployed from a first position to a second position, wherein in the first position the wheel is housed within the pin body and in the second position at least a portion of the wheel extends from the pin body.

14. The mat system of claim 13 , wherein the plurality of pin apertures of the first lip structure align with the plurality of pin apertures of the second lip structure to define a plurality of additional aligned pin apertures.

15. The mat system of claim 14 , further comprising a plurality of locking pins inserted into the plurality of additional aligned pin apertures.

16. The mat system of claim 15 , wherein at least one locking pin of the plurality of locking pins comprises an additional wheeled pin.

17. The mat system of claim 15 , wherein each locking pin of the plurality of locking pins comprises a wheeled pin.

18. A method comprising:

positioning a first mat having a first pin aperture adjacent to a second mat having a second pin aperture;

aligning the first pin aperture of the first mat with the second pin aperture of the second mat; and

inserting a pin having a wheel assembly into the first pin aperture and the second pin aperture.

19. The method of claim 18 , further comprising moving the wheel assembly from a first position in which the wheel assembly is retracted into the pin to a second position in which the wheel assembly is extended from the pin.

20. The method of claim 19 , further comprising moving the first mat and the second mat along a surface with the wheel assembly in contact with the surface.
