Universal bracket and luggage handle system
View Patent ↗The invention includes a universal retractable handle assembly for attachment to luggage items of a variety of different sizes. A plurality of tubes having a fixed length can be attached to a bracket member such that each tube can extend in a telescoping manner to a different distance from the bracket member when the handle is in the extended position and thus be employed in different sizes of luggage. Additionally, a tube housing is provided which includes a tube receiving portion and reinforcing portions on an outer surface of the tube housing. The tube receiving portion is formed with an arcuate shape which corresponds with the shape of the tube member to be inserted therein. The reinforcing portions include a plurality of planar flanges which extend beyond the outer surface of the tube receiving portion to provide improved structural characteristics.
1. A tube housing for a retractable handle assembly comprising:
a tube receiving portion having a first side and a second side and an inner surface and an outer surface, the inner surface configured to have a shape generally corresponding to a tube inserted therein;
at least a first reinforcing portion disposed on the outer surface configured to protect the tube receiving portion, the first reinforcing portion comprising a sidewall extending parallel to and extending from the outer surface of the first side of the tube receiving portion and a flange coupled to an end of the sidewall and substantially perpendicular to the sidewall; and
a second reinforcing portion disposed on the outer surface configured to protect the tube receiving portion, wherein the second reinforcing portion is disposed opposite the first reinforcing portion, the second reinforcing portion comprising a sidewall extending parallel to and extending from the outer surface of the second side of the tube receiving portion and a flange coupled to an end of the sidewall and substantially perpendicular to the sidewall.
2. The tube housing of claim 1 , wherein the first reinforcing portion extends a distance from the first side of the tube receiving portion at least equal to a distance from the center point of the tube receiving portion to the outer surface of the tube receiving portion.
3. The tube housing of claim 2 , wherein the first reinforcing portion extends a distance greater than the distance from the center point of the tube receiving portion to the outer surface of the tube receiving portion.
4. The tube housing of claim 2 , wherein the first reinforcing portion distance is measured along a line generally parallel to the sidewall of the first reinforcing portion.
5. The tube housing of claim 1 , wherein the flange of the first reinforcing portion and the flange of the second reinforcing portion extend toward the center of the tube reinforcing portion.
6. The tube housing of claim 5 , wherein the flange of the first reinforcing portion and the flange of the second reinforcing extend in the same plane.
7. The tube housing of claim 6 , wherein the flange of the first reinforcing portion and the flange of the second reinforcing portion do not connect.
8. The tube housing of claim 1 , wherein the second reinforcing portion extends a distance from the second side of the tube receiving portion at least equal to a distance from the center point of the tube receiving portion to the outer surface of the tube receiving portion.
9. The tube housing of claim 1 , wherein the tube receiving portion has a generally gumdrop shape.
10. The tube housing of claim 9 , wherein the first and second sides of the tube receiving portion are generally planar.
11. The tube housing of claim 10 , wherein the tube receiving portion further comprises a front portion between the first and second sides, the front portion having a generally arcuate shape.
12. The tube housing of claim 1 , wherein the sidewall of the first reinforcing portion and the sidewall of the second reinforcing portion are generally planar.
13. The tube housing of claim 1 , wherein the sidewall of the first reinforcing portion and the sidewall of the second reinforcing portion extend parallel to each other.
14. The tube housing of claim 1 , wherein at least one of the first and second reinforcing portions further comprises an angled portion extending from the outer surface of the tube receiving portion and toward the sidewall.
15. The tube housing of claim 14 , wherein an end of the angled portion is coupled to one of the flange of the first reinforcing portion or the flange of the second reinforcing portion.
16. The tube housing of claim 15 , wherein the angled portion, the flange, the sidewall and the outer surface of the tube receiving portion are coupled together so as to define a cavity therebetween.
17. The tube housing of claim 1 , further comprising a bracket member, wherein the bracket member and the tube form the retractable handle assembly for attachment to a piece of luggage, wherein:
the bracket member has at least one receiving portion, the at least one receiving
portion having a segment defined by a first end and a second end, with a plurality of connection locations disposed along the segment;
the tube housing disposed within the at least one receiving portion of the bracket member;
the tube configured to be disposed within the tube housing, the tube adapted for extending beyond the second end of the at least one receiving portion; and
the tube extends to a first distance from the second end when the tube is coupled to the at least one receiving portion at a first of the plurality of connection locations, and the tube extends to a second distance from the second end when the tube is coupled to the at least one receiving portion at a second of the plurality of connection locations, wherein the second distance is greater than the first distance.
