Abstract

An artificial tree has a trunk (2), at least one tubular bracket (4) for fitting on the trunk, a fixing ring (6) and a branch (12) having a stem portion, wherein the tubular bracket (4) defines an opening for insertion of an end of the stem, the fixing ring (6) being adapted to fit over the tubular bracket and to be deformable so as to tightly grip the tubular bracket.

Claims

1. An artificial tree comprising a trunk, at least one tubular bracket for fitting on the trunk, a fixing member, and at least one branch having a stem portion, wherein the tubular bracket at least partly defines an opening for insertion of an end of the branch stem portion, the fixing member being adapted to fit over the tubular bracket and to be deformable so as to tightly grip the tubular bracket, wherein the stem of the branch is formed of a metal wire which has an elongate cross-section such that when fitted the or each branch may be bent by a user towards or away from the trunk.

2. An artificial tree according to claim 1 wherein the fixing member is a metal ring which overlies the tubular bracket and may be stamped whereby the ring is compressed onto the tubular bracket.

3. An artificial tree according to claim 1 wherein the bracket is formed with a plurality of longitudinally-extending grooves which define with the trunk the openings for insertion of the branch stem.

4. An artificial tree according to claim 3 wherein the grooves are formed in outwardly-protruding portions.

5. An artificial tree according to claim 1 wherein the tubular bracket is formed of plastics material.

6. An artificial tree comprising a trunk, at least one tubular bracket for fitting on the trunk, a fixing member, and at least one branch having a stem portion, wherein the tubular bracket at least partly defines an opening for insertion of an end of the branch stem portion, the fixing member being adapted to fit over the tubular bracket and to be deformable so as to tightly grip the tubular bracket, wherein the bracket is formed with a plurality of longitudinally-extending grooves which define with the trunk the openings for insertion of the branch stem.

7. An artificial tree according to claim 6, wherein the grooves are formed in outwardly-protruding portions.

8. An artificial tree comprising a trunk, at least one tubular bracket fitted on the trunk, and at least one branch having a stem portion fitted in an opening at least partly defined by the tubular bracket, and a fixing member which fits over the tubular bracket and is deformed so as to tightly grip the tubular bracket.

9. An artificial tree according to claim 8 wherein the fixing member is a metal ring stamped to compress the tubular bracket therein.

10. An artificial tree according to claim 8 wherein the stem of the branch is formed of a metal wire which has an elongate cross-section.

11. An artificial tree according to claim 8 wherein the bracket is formed with a plurality of longitudinally-extending grooves which define with the trunk the openings in which the branch stem portions are fitted.

12. An artificial tree according to claim 11 wherein the grooves are formed in outwardly-protruding portions.

13. An artificial tree according to claim 8 wherein the tubular bracket is formed of plastics.

14. An artificial tree comprising a trunk, at least one tubular bracket fitted on the trunk, and at least one branch having a stem portion fitted in an opening at least partly defined by the tubular bracket, and a fixing member which fits over the tubular bracket so as to tightly grip the tubular bracket, wherein the stem of the branch is formed of a metal wire which has an elongate cross-section.

15. An artificial tree comprising a trunk, at least one tubular bracket fitted on the trunk, and at least one branch having a stem portion fitted in an opening at least partly defined by the tubular bracket, and a fixing member which fits over the tubular bracket so as to tightly grip the tubular bracket, wherein the bracket is formed with a plurality of longitudinally-extending grooves which define with the trunk the openings in which the branch stem portions are fitted.

16. An artificial tree according to claim 15 wherein the grooves are formed in outwardly-protruding portions.

17. A method of mounting at least one branch to the trunk of an artificial tree which has at least one tubular bracket and a fixing member, the branch having a branch stem portion, the method comprising the steps of:

(a) Inserting the tubular bracket and fixing member onto the trunk so that the fixing member fits over the tubular bracket;

(b) fitting the or each branch on the trunk by inserting the end of the stem portion into an opening or respective openings at least partly defined by the tubular bracket; and

(c) deforming the fixing member so as to tightly grip the tubular bracket and branch stem or stems therein.

18. A method according to claim 17 in which the fixing member is a fixing ring, and wherein in step (c) the fixing member is deformed by a stamping operation to grip the tubular bracket therein.

19. A method according to claim 17 in which the tubular bracket is provided with at least one longitudinally-extending groove which defines with the trunk the insertion opening, the branch stem being inserted into the said opening at step (b).

20. A method according to claim 17 wherein the or each branch is fitted such that the branch extends generally parallel to the trunk and is subsequently bent away from the trunk to extend more radially therefrom.

21. A method according to claim 17 in which before step (b), the tubular bracket is secured onto the trunk with a pin or staple forced through the tubular bracket and into the trunk.
