Abstract

A crutch includes an arm rest having an elbow end and a front end, the front end defining a front face having a first opening formed therein, and a bottom edge forming a second opening. The crutch has a handle extending outwardly from the front end of the arm rest, but not from the first or second openings. A leg is received into one of the first and second openings in a first configuration, and into the other of the first and second openings in a second configuration. The leg is selectively convertible between the first and second configuration.

Claims (45)

1. A crutch, comprising:

an arm rest, comprising a first and a second opening formed therein;

a handle extending outwardly from a front end of the arm rest, wherein the handle does not extend from the first and second openings in the arm rest; and

a leg selectively received into one of the first and second openings in the arm rest;

wherein:

the first opening extends along a horizonal axis substantially parallel with the arm rest; and

the second opening extends along a generally vertical axis, the generally vertical axis intersecting the horizontal axis.

2. The crutch of claim 1 , wherein the leg comprises a first angled section and a second substantially vertical section, the first angled section and the second substantially vertical section being of a unitary configuration, wherein the first angled section is received into one of the respective openings in the arm rest.

3. The crutch of claim 2 , wherein the first angled section is angled in a front-to-rear orientation; and wherein the angle is between approximately 0 and 45 degrees relative to vertical.

4. The crutch of claim 3 , wherein the leg further comprises a third-section angled in a side-to-side orientation.

5. The crutch of claim 1 , wherein a rear end of the main body comprises an elbow cup for receiving a user's elbow; and wherein the elbow cup comprises a cutout.

6. The crutch of claim 1 , wherein each of the first and second openings in the arm rest comprises a plurality of anti-rattle teeth defined around a perimeter thereof.

7. The crutch of claim 6 , wherein an inner diameter of the first and second openings in the arm rest is smaller than an outer diameter of the leg.

8. The crutch of claim 1 , wherein the leg comprises a cap, the cap defining a key.

9. The crutch of claim 8 , wherein the cap corresponds to a keyed opening defining each of the first and second openings for selectively receiving the leg into one of the first and second openings.

10. A crutch, comprising:

an arm rest having an elbow end and a front end, the front end defining a front face having a first opening formed therein, and a bottom edge forming a second opening;

a handle extending outwardly from the front end of the arm rest, wherein the handle does not extend from the first or second openings; and

a leg;

wherein:

in a first configuration, the leg is received into one of the first and second openings;

in a second configuration, the leg is received into the other of the first and second openings; and

the leg is selectively convertible between the first and second configuration.

11. The crutch of claim 10 , wherein:

the arm rest further comprises a locking lever comprising a projection;

the projection is received into a first hole defined in the leg when the leg is in the first configuration; and

the projection is received into a second hole defined in the leg when the leg is in the second configuration.

12. The crutch of claim 11 , wherein the first and second holes defined in the leg are at different locations along the length of the tube.

13. The crutch of claim 11 , wherein each of the first and second openings in the arm rest comprises a plurality of teeth defined around a perimeter thereof.

14. The crutch of claim 11 , wherein the leg comprises a cap, the cap defining a key.

15. The crutch of claim 14 , wherein the cap corresponds to a keyed opening defining each of the first and second openings for selectively receiving the leg into one of the first and second openings.

16. The crutch of claim 14 , wherein the cap comprises an anti-rattle.

17. The crutch of claim 11 , wherein the arm rest comprises a padding extending over an edge of the arm rest.

18. The crutch of claim 11 , wherein an arm band extends at least partially over the arm rest; and wherein the arm band is downwardly angled from the elbow end to the front end.

19. A crutch, comprising:

an arm rest having a front end and a rear end, the front end having a first opening formed in a front face thereof, and a second opening formed at a bottom edge thereof; and

a handle extending outwardly from a front end of the arm rest support;

a leg having a cap at one end defining a key;

wherein:

each of the first and second openings define a keyed opening corresponding to the cap;

in a first configuration, the leg is received into one of the first and second openings;

in a second configuration, the leg is received into the other of the first and second openings;

the leg is selectively convertible between the first and second configuration;

a projection extending from a lever in the arm rest protrudes into a first hole defined in the leg when the leg is in the first configuration and into a second hole defined in the leg when the leg is in the second configuration; and

the lever is actuated by a user to convert the leg between the first and second configurations.
