Abstract

A foot operated pump guard assembly for a portable pump includes a pair of upwardly extending support legs connected at their lower ends to a pump. A foot guard substantially surrounds an operator'"'"'s foot and is pivotally connected to the upwardly extending support legs. Springs react against one another to cause the guard to self return upon removal of the operator'"'"'s foot from the guard assembly. The guard has a built-in locking device and a carrying means to enhance in its transportability.

Claims

1. A guard assembly for a portable foot operated pump comprising:

a first upwardly extending bracket member having a spring receiving portion on one end and a flange that is operable to be secured to a pump at another end;

a second upwardly extending bracket member spaced apart from the first bracket member;

a guard pivotally connected to said first and second bracket members, the guard having a substantially planar surface and pair of flanges extending downwardly therefrom, the planar surface having handle means and a recess for receiving a foot;

connecting members for pivotally connecting the guard to the bracket members;

bushings disposed between the guard and the bracket members;

a spring connected to the guard and one of the bracket members for biasing the guard in a first position; and

a stop connected to the guard for preventing the guard from rotating to an undesirable position.

2. The guard assembly as claimed in claim 1, wherein the second upwardly extending bracket member has a spring receiving portion on one end and a flange that is operable to be secured to a pump at another end.

3. The guard assembly as claimed in claim 1, further comprising a pin that is operable to lock the guard and a bracket member relative to one another.

4. The guard assembly as claimed in claim 1, wherein the bushings are made of nylon.

5. The guard assembly as claimed in claim 1, further comprising a fluid pump secured to the bracket members.

6. The guard assembly as claimed in claim 1, further comprising a pedal pivotally connected to the fluid pump.

7. A portable foot operated pump having a guard assembly comprising:

a portable pump;

support legs extending upwardly from the portable pump;

a guard with a main section and side sections extending downwardly therefrom towards the support legs;

a pivot member connecting the guard to the support legs; and

a spring member connected to the support legs and to the guard, the spring member operable to bias the guard to a desired position.

8. The portable foot operated pump as claimed in claim 7, wherein the pump has flanges extending outwardly therefrom for engaging the support legs.

9. The portable foot operated pump as claimed in claim 7, wherein the pump has a pedal pivotally connected thereto.

10. The portable foot operated pump as claimed in claim 7, wherein each support leg has a substantially vertical planar surface, a mounting flange extending normal thereto and an offset portion extending from the planar surface.

11. The portable foot operated pump as claimed in claim 7, further comprising a locking device insertable through the guard and the support legs for preventing the guard from pivoting relative to the support legs during a locking mode.

12. The portable foot operated pump as claimed in claim 7, further comprising a bushing located between the support legs and the guard.

13. The portable foot operated pump as claimed in claim 7, further comprising a stop member secured to each side section of the guard for limiting movement of the guard.

14. The portable foot operated pump as claimed in claim 7, further comprising another spring member connected to one of the other support legs and to the guard.

15. The portable foot operated pump as claimed in claim 7, wherein the main section of the guard has an oval-shaped handle.

16. The portable foot operated pump as claimed in claim 7, wherein the main section of the guard has a concave recess.

17. The portable foot operated pump as claimed in claim 7, wherein the pivot member consist of a self-locking nut and a bolt.

18. A guard assembly for a control device comprising:

a U-shaped guard substantially surrounding a switch;

a locking device for aiding transport of the guard assembly;

a support member for pivotally supporting the U-shaped guard; and

a biasing member connected to the guard and support member for returning the U-shaped guard to a predetermined position.

19. The guard assembly as claimed in claim 18, further comprising a stop fixed to the guard for limiting pivotal rotation of the guard relative to the support member.

20. The guard assembly as claimed in claim 18, wherein the guard has a handle.
