Abstract

The present invention relates generally to accessories for classroom furniture items. In some embodiments, an accessory for a classroom furniture item having at least two legs comprise at least two supports wherein each support is configured to surround at least a portion of a leg of an item of classroom furniture, and an elastic cord comprising two ends, wherein a first end is configured to be coupled to a first leg of the item above a first support and wherein a second end is configured to be coupled to a second leg of the item above a second support. Some embodiments of the present invention also relate to portable leg movement accessories.

Claims

1. An accessory for an item of classroom furniture item having at least two substantially vertical legs, the accessory comprising:

a first support and a second support, wherein the first support is configured to surround at least a portion of a first leg of the at least two substantially vertical legs of the item of classroom furniture and contact a first substantially horizontal surface supporting the first leg, and the second support is configured to surround at least a portion of a second leg of the at least two substantially vertical legs and contact a second substantially horizontal surface supporting the second leg; and

an elastic cord comprising two ends, wherein a first end is configured to surround the first leg of the at least two substantially vertical legs and wherein a second end is configured to surround the second leg of the at least two substantially vertical legs,

wherein the first and the second supports are configured to contact the first and second ends, respectively, of the elastic cord so as to position the elastic cord at a fixed distance between a point of contact of a respective support with the elastic cord and a point of contact of the respective support with a respective substantially horizontal surface.

2. The accessory of claim 1, wherein each support comprises a hollow tube.

3. The accessory of claim 2, wherein the hollow tube has a circular cross-section with a diameter of at least 1.25 inches.

4. The accessory of claim 3, wherein the hollow tube comprises at least one hinge.

5. The accessory of claim 1, wherein the first or second support has a length of at least six inches.

6. The accessory of claim 5, wherein the first or second support has a length of 12 inches or less.

7. The accessory of claim 1, wherein the first or second support is constructed from plastic or bamboo.

8. The accessory of claim 1, wherein the first end of the elastic cord comprises a first loop configured to slide over the first leg and wherein the second end of the elastic cord comprises a second loop configured to slide over the second leg.

9. A chair comprising the accessory of claim 1, wherein the first support is positioned on a first chair leg, wherein the second support is positioned on a second chair leg, wherein the first end of the elastic cord is coupled to the first leg above the first support, wherein the second end of the elastic cord is coupled to the second leg above the second support, and wherein the first and second supports prevent the elastic cord from sliding down the first and second chair legs, respectively.

10. A desk comprising the accessory of claim 1, wherein the first support is positioned on a first desk leg, wherein the second support is positioned on a second desk leg, wherein the first end of the elastic cord is coupled to the first leg above the first support, wherein the second end of the elastic cord is coupled to the second leg above the second support, and wherein the first and second supports prevent the elastic cord from sliding down the first and second desk legs, respectively.

11. An accessory for an item of classroom furniture having at least two substantially vertical legs, the accessory comprising:

a first hollow tube and a second hollow tube, wherein the first hollow tube and the second hollow tube each have a length of at least six inches, wherein the first hollow tube is configured to surround at least a portion of a first leg of the at least two substantially vertical legs of the item of classroom furniture and contact a first substantially horizontal surface supporting the first leg, and the second hollow tube is configured to surround at least a portion of a second leg of the at least two substantially vertical legs and contact a second substantially horizontal surface; and

an elastic cord comprising two ends, wherein a first end is configured to surround the first leg of the at least two substantially vertical legs and wherein a second end is configured to surround the second leg of the at least two substantially vertical legs

wherein the first and the second hollow tubes are configured to contact the first and second ends, respectively, of the elastic cord so as to position the elastic cord at a fixed distance between a point of contact of a respective hollow tube with the elastic cord and a point of contact of the respective hollow tube with a respective substantially horizontal surface.

12. The accessory of claim 11, wherein the first or second hollow tube has a circular cross-section with a diameter of at least 1.25 inches.

13. The accessory of claim 11, wherein the first or second hollow tube comprises at least one hinge.
