Description

Kit for constructing the trunk of an artificial tree and artificial tree

Technical Field

The subject matter of the present disclosure generally relates to connectors for components of artificial trees and stabilizers thereof.

Background

People celebrating christmas or other holidays are accustomed to bringing natural evergreen trees indoors to decorate the trees with decorations, lights, wreaths, foil, and the like. However, natural trees can be quite expensive and are considered by some to be a waste of environmental resources. Furthermore, natural trees can be intractable, require water to prevent the trees from drying out, and can be messy, leaving sap and/or coniferous leaves after removal. In addition, if the tree is not watered sufficiently, it can become so dry that it becomes a fire hazard. At each vacation, a new tree must be obtained and decorated, and at the end of the vacation, the decorations must be removed. By then, the needle blade has often dried out and may be quite sharp, so that removal of the decoration may be a painful process. Moreover, natural trees are often disposed of in landfills, further contaminating the flooded environment.

To overcome the disadvantages of natural trees and still celebrate with christmas trees, a wide variety of artificial trees are available. In most cases, these artificial trees must be assembled for use and disassembled after use. Artificial trees have the advantage of being usable over a period of several years, thereby eliminating the annual expenses of purchasing live trees for short holidays. Furthermore, they contribute to reducing: trees are cut down for temporary decoration and then typically disposed of in a landfill.

In general, most artificial christmas trees include a wide variety of individual branches, each formed from a large number of plastic needles that are held together by wrapping a pair of wires around the plastic needles. In other cases, the branches are formed by winding a pair of wires around an elongated sheet of plastic material having a large multiplicity of transverse sipes. In other artificial christmas trees, the branches are formed by injection molding of plastic.

Regardless of the form of the branches, the most common form of artificial christmas trees comprises a plurality of torso members connected to one another to form a trunk. For example, the first and second torso members, each include an elongated body. Near the first end of the first torso member, the body of the first torso member is slightly tapered to reduce the diameter of the body. The second end of the second torso member includes a receiving portion (e.g., a female end), and a tapered first end that serves as an extension (e.g., a male end). Typically, the torso has a generally cylindrical shape. In other words, the diameter of the second end (i.e., the receptacle) is larger than the diameter of the tapered first end (extension). The first end is inserted into the second end for attachment to the torso member. For example, the extension portion of the first torso member is inserted into the non-extension portion of the second torso member.

The torso design that extends the extension to the receiving end is still imperfect. Due to the difference in diameter of the tapered end and the receiving end, an extension extending to a certain point may slide into the receiving end to form a continuous torso. However, the first torso member is allowed to move and pivot relative to the second torso member due to the difference between the outer diameter of the received portion of the extension portion and the inner diameter of the receiving end. For example, the extension is allowed to pivot about the top of the receiving end, wherein the diameter of the extension increases to no longer allow reception of the portion beyond that point. This free movement about the pivot point may result in uneven loading because the extension pivots slightly to the side opposite the side that rests evenly about the receiving end. Over time, uneven loading may cause the torso to bend and possibly break over time.

SUMMERY OF THE UTILITY MODEL

The above and other concerns are addressed by the subject matter of the present disclosure. Briefly, the subject matter of the present disclosure relates to a connector system for connecting a first torso member to a second torso member. The connector system may include a ferrule. The sleeve may have a substantially cylindrical internal shape or any internal shape that conforms to the external shape of the artificial tree trunk system. The sleeve may have a first end and a second end. The first end may include a lower edge that may be angled downward. The interior of the sleeve may comprise two adjacent portions. The first portion may have an inner wall comprising an axially extending rib. The axially extending ribs may provide a snug fit between the sleeve and the first torso member after the first torso member is inserted into the first portion of the sleeve. The second portion may have an inner wall comprising an annularly extending rib. The annularly extending rib may provide a press fit between the sleeve and the second trunk after the second trunk is inserted into the sleeve. When assembled, the sleeve may provide reinforcement for the connection of the first and second torso members, while also reducing or eliminating movement or pivoting between the two torso members.

The present disclosure relates to a kit for constructing an artificial tree trunk, the kit comprising:

In one exemplary and non-limiting embodiment, the subject of the present disclosure is a kit for constructing an artificial tree trunk. The kit has a first tree trunk having a first diameter, the first tree trunk narrowing to form an extension end having a second diameter, and a second tree trunk having a receiving end having a diameter configured to receive the extension end. The kit may have more than two portions, a first torso member and a second torso member. The number of torso members is merely for purposes of describing aspects of the disclosed subject matter and is not intended to limit the present disclosure. The kit also has a generally hollow sleeve having a first sleeve end with a first inner diameter generally equal to the first torso member and a lower edge with an angled portion. The sleeve also has a second sleeve end having a second inner diameter substantially equal to the second torso member. The sleeve also has an inner narrowed region narrowing from a first inner diameter substantially equal to the first torso member to a second inner diameter substantially equal to an extension of the first torso member. The kit also has a swivel tab extending through a wall of the first torso member. During assembly of the artificial tree, the rotating projection may interact with the lower edge at a plurality of points along the angled portion.

Another exemplary and non-limiting embodiment of the present disclosure is a method for assembling a tree trunk of an artificial tree. The receiving end of the second torso member is inserted into the second end of the sleeve. The extended end of the first torso member is inserted into the first end of the sleeve. The angled portion of the lower edge of the first end of the sleeve and the rotational tab facilitate interlocking of the first and second torso members. In this example, the first end has an inner diameter substantially equal to the extended end of the first torso member, and the second end has an inner diameter substantially equal to the receiving end of the second torso member.

To facilitate an understanding of the principles and features of the present invention, various illustrative embodiments are explained below. In particular, the subject matter of the present disclosure is described in the context of a connector system for assembling an artificial tree. However, embodiments of the presently disclosed subject matter are not limited to use in artificial trees. Of course, embodiments of the present invention may also be used to assemble other objects, such as poles.

Referring now to the drawings, wherein like reference numerals refer to like parts throughout the several views, a connector system will be described in detail.

Typically, a conventional artificial tree comprises a plurality of tree trunks which can be connected to each other. Fig. 1 shows a partial cross-sectional view of a conventional artificial tree system including a hollow first torso member 110, the hollow first torso member 110 being connected to a hollow second torso member 120. For clarity, the first and second torso members are shown without branches, but the branches may extend radially outward from the torso members. The first torso member 110 may include an elongated body 112 and an extension 114. The second torso member 120 may include an elongated body 122 and a receptacle 124. Extension portion 114 of first torso member 110 may be configured to be at least partially inserted into receptacle 124 of second torso member 120. Conversely, the receptacle 124 may be configured to at least partially receive the extension 114. The

torso members

110, 120 may comprise metal (e.g., steel), plastic, or any other useful material.

The

elongated bodies

112, 122 may have a cross-sectional shape that is circular, oval, triangular, rectangular, square, or any other desired shape. As will be appreciated, a trunk having a cylindrical shape (i.e., a circular cross-sectional shape) may be most commonly desired because the cylindrical shape most closely resembles the shape of a natural tree trunk. The extension 114 may be capped or open-ended. First torso member 110 may have a first outer diameter at main body 112 and a second outer diameter at extension 114. The outer diameter (i.e., the second outer diameter) of the extension 114 may be smaller than the outer diameter (i.e., the first outer diameter) of the body portion 112. The outer diameter of the first torso member may transition between the first and second outer diameters at tapered region 116, which may separate elongated body 112 from extension 114.

The elongated body 122 of the second torso member 120 may have an outer diameter that is substantially equal to the outer diameter (i.e., the first outer diameter) of the elongated body 112 of the first torso member 110. Receiving portion 124 of second torso member 120 may have an inner diameter that is greater than the outer diameter (i.e., second outer diameter) of extension 114 of first torso member 110 such that receiving portion 114 may at least partially receive extension 114 of first torso member 110. For example, receptacle 124 may be configured to receive an end portion of first torso member 110 (i.e., extension 114) until tapered region 116 of first torso member 110 has an outer diameter substantially equal to an inner diameter of receptacle 124 of second torso member 120, such that at least a portion of tapered region 116 may abut an end portion of second torso member 120.

The difference between the inner diameter of receptacle 124 and the second outer diameter of extension 114 (e.g., due to variations during manufacturing) may result in a gap (not shown) being created between the outer surface of extension 114 of first torso member 110 and the inner surface of receptacle 124 of second torso member 120. This gap may allow extension 112 to move freely within receptacle 124 of second torso member 120, which may result in first torso member 110 pivoting relative to second torso member 120 at tapered region 116. Over time, the uneven loading ultimately resulting from the pivoting may cause first torso member 110 and/or second torso member 120 to become bent, skewed, and/or otherwise deformed.

As shown in fig. 2, the techniques of the present disclosure include a connector system 200, and the connector system 200 may include a ferrule 202. As described more fully below, the connector system 200 may provide reinforcement for the connection of the first and

second torso members

110, 120 while also reducing or eliminating movement or pivoting between the two

torso members

110, 120. Thus, the connector system 200 may help prevent uneven loading and/or eventual damage to the

torso members

110, 120.

Further, sleeve 202 may be used to protect the ends of the

torso members

110, 120 during transport or storage. For example, during transport, the

torso members

110, 120 may be subjected to a force that compresses an end of one or more of the

torso members

110, 120. By providing the sleeve 202 on the end of the

body portion

110, 120, the sleeve 202 can protect the end of the

body portion

110, 120 to which the sleeve 202 is attached. Sleeve 202 may be constructed of a stronger or stronger material than

body portions

110, 120 and/or may have a geometry that is more resistant to compressive forces than

body portions

110, 120.

Referring to fig. 2, sleeve 202 may have an internal shape that substantially corresponds to the external shape of first and

second torso members

110, 120. For example, the sleeve 202 may have a substantially cylindrical internal shape. The sleeve 202 may have an outer shape that is the same as its inner shape. For example, the sleeve 202 may have a substantially cylindrical inner shape and a substantially cylindrical outer shape. Alternatively, the sleeve 202 may have an outer shape that is different from its inner shape. For example, the sleeve 202 may have a blocky (i.e., square or rectangular prism) or asymmetric outer shape. The outer surface of the sleeve 202 may be smooth and/or void-free. Alternatively, the outer surface of the sleeve 202 may have ribs or channels, a grid structure, or some other structure in which the material of the outer surface of the sleeve 202 is reduced. Thus, the sleeve 202 may have the same or substantially the same strength, stiffness, and/or structural characteristics as a solid sleeve, while using less material than a solid sleeve, which may reduce manufacturing costs.

Sleeve 202 may facilitate a secure mechanical connection between first torso member 110 and second torso member 120 by providing additional stability at the point of connection of first and

second torso members

110, 120. Sleeve 202 may surround and/or overlap a portion of elongate body 112 of first torso member 110 (i.e., proximate tapered region 116), tapered region 116 of the first torso member, and a portion of elongate body 122 of second torso member 120 (i.e., proximate receptacle 124). The sleeve 202 may have multiple portions. For example, the sleeve 202 may have a first portion 204, a second portion 206, and an inner protrusion 208. First portion 204 of sleeve 202 may have an inner diameter that is slightly larger than the outer diameter of body 112 of first torso member 110 (i.e., the first outer diameter of first torso member 110). Second portion 206 of sleeve 202 may have an inner diameter slightly larger than the outer diameter of elongated body 122 of second torso member 120. The first portion 204 and the second portion 206 of the sleeve 202 may have the same inner diameter, or they may have different inner diameters.

The inner protrusion 208 may define a variable inner diameter of the cannula 202. By way of non-limiting example, the inner protrusion 208 may taper on one or both sides. The inner protrusion 208 may correspond to the tapered region 116 of the first torso member 110. For example, the inner protrusion may reflect the taper of the tapered region 116. Thus, the inner protrusion 208 may abut a portion of the tapered region 116. The inner protrusion 208 may be configured to also abut a portion of the receptacle 124 of the second torso member 120 (e.g., an edge of the receptacle 124). Additionally, the inner protrusion 208 may be configured to effectively "plug" into any pivot region between the tapered region 116 of the first torso member 110 and the edge of the receptacle 124 of the second torso member 120.

As described herein, the various portions of sleeve 202 may be sized to provide a tight fit with respect to the corresponding portions of first and

second torso members

110, 120, such that sleeve 202 may limit any free movement and/or pivoting between first and

second torso members

110, 120 about tapered region 116. Thus, connector system 200 may provide a more balanced load across the torso of the tree and may reduce any chance of damage and/or distortion to the tree.

Sleeve 202 may include ribs to help facilitate a desired fit with first torso member 110 and/or second torso member 120. The sleeve 202 may include a first plurality of ribs and a second plurality of ribs, and the first plurality of ribs may be oriented differently on the sleeve 202 than the second plurality of ribs. For example, referring to fig. 3-5, the sleeve 202 may include a first end 310 including a first plurality of ribs 312 and a second end 320 including a second plurality of ribs 322. The first plurality of ribs 312 may protrude inward from the inner wall of the sleeve 202 and may be substantially axially aligned (i.e., substantially parallel to the central axis of the sleeve 202). Each rib of the first plurality of ribs 312 is substantially parallel. The axial direction of the first plurality of ribs 312 may allow a predetermined amount of sliding relative to the body 112 or some other portion of the first torso member. To allow for enhanced sliding, the number of ribs may be reduced and/or the protrusion distance of some or all of the ribs may be reduced. Conversely, to enhance sliding, the number of ribs may be increased, the protrusion distance of some or all of the ribs may be increased, and/or the angle of some or all of the ribs with respect to the central axis of the cannula 202 may be increased. The sliding between first end 310 and first torso member 110 may allow first torso member 110 to be easily inserted into sleeve 202 and removed from sleeve 202, while also providing a tight enough fit to prevent first torso member 110 from pivoting or jostling relative to second torso member 120.

The second plurality of ribs 322 may protrude inward from the inner wall of the sleeve 202 (e.g., at the second end 320) and may be generally annular (i.e., disposed about the circumference of the inner wall of the sleeve). Each rib of the second plurality of ribs 322 is substantially parallel. Each rib of the second plurality of ribs 322 may extend about a central axis of the sleeve 202. Additionally, each rib of the second plurality of ribs 322 may lie in a plane that is substantially perpendicular to the axis of the cannula 202. The annular positioning of the second plurality of ribs 322 may facilitate a semi-permanent connection between the sleeve 202 and the second torso member. As will be appreciated by those skilled in the art, a "semi-permanent fit" may also be referred to as a "tight fit" and may involve one of the following interference fits: one of the parts may be assembled into the other by hand pressure and/or by hand hammer; the two components will remain connected unless there is a significant pulling force to separate them. To reduce the tightness or permanence of the fit, the annular ring may be angled such that the ribs are no longer substantially perpendicular to the axis of the sleeve 202. To increase the tightness or permanence of the fit, the protruding distance of the second plurality of ribs 322 may be increased and/or the inner diameter of the second end 320 of the sleeve 202 may be decreased to more closely match the outer diameter of the extension 114 of the first torso member 110. For example, the inner diameter of the second plurality of ribs 322 and/or the second end 320 of the sleeve 202 may be sized such that the smallest inner diameter of the second end 320 is slightly smaller than the outer diameter of the second torso member 120. As a non-limiting example, a press fit may be formed when the second torso member 120 is inserted into the second end 320.

Alternatively or additionally, the first plurality of ribs 312 and/or the second plurality of ribs 322 may be provided in a spiral or filamentary form such that the respective first or

second torso member

110, 120 may be inserted and/or removed by a twisting action. Alternatively or additionally, glue, epoxy, or other adhesive may be applied between the inner surface of second end 320 and/or the outer surface of second torso member 120. Alternatively or additionally, mechanical fastening members (e.g., screws, bolts) may attach the ends of sleeve 202 to second torso member 120. One or some of these and other attachment methods may be used to alter the durability of the attachment between sleeve 202 and second body portion 120 as desired.

While sleeve 202 is described herein as having a more permanent connection to second torso member 120 than to first torso member 110, the reverse is also possible. That is, sleeve 202 may be provided to be more permanently attached to first torso member 110 than if sleeve 202 were attachable to second torso member 120.

Alternatively or additionally, either end of the sleeve (i.e., first end 310 or second end 320) may be configured to connect or attach to either end of the torso member (i.e., male or female). That is, both the first end 310 and the second end 320 of the sleeve may be attached to the body 112 of the first torso member 110 or the elongate body 122 of the second torso member 120.

As described above, the inner protrusion 208 may be tapered on one or both sides. With particular reference to FIG. 5, the inner protrusion 208 may be tapered on one side and have a substantially flat step on the opposite side. The tapered sides of the inner protrusion 208 may be configured to mirror the tapered region 116 of the first torso member 110, and the slat step of the inner protrusion 208 may be configured to abut the edge of the receptacle 124 of the second torso member 120. This design may provide the most effective "plugging" of the pivot region between tapered region 116 of first torso member 110 and the edge of receptacle 124 of second torso member 120.

Referring to fig. 6A-8, the connector system 200 may be a multi-piece ferrule system. For example, the connector system 200 may include a male ferrule 610 and a female ferrule 720. The male sleeve 610 may have an outer diameter that is substantially equal to the inner diameter of the extension 114 of the first torso member 110. The male sleeve 610 may have a rim 612, the rim 612 configured to abut and/or overlap the rim of the extension. Rim 612 may have an outer diameter substantially equal to the outer diameter of extension 114. The male sleeve 610 may include an anti-rotation member 614. The anti-rotation member 614 may be a screw or bolt. The anti-rotation member 614 may extend through a wall of the first torso member 110. The anti-rotation member 614 may extend through the wall of the first torso member 110 and the portion of the male sleeve 610 that extends into the interior of the first torso member 110.

The female sleeve 720 may have an inner diameter substantially equal to the outer diameter of the receptacle 124 of the second trunk 120. The female sleeve 720 may include an overlapping portion 722 that abuts the outer surface of the receptacle 124 and an extending portion 724 that extends axially beyond the edge of the receptacle 124. The overlap portion 722 may have an annular rib (e.g., similar to the rib 322 of the second end 320 of the sleeve 202). Alternatively or additionally, the ribs of the overlap portion 722 may be provided in a spiral or wire-like form so that the second torso member 120 may be inserted and/or removed by a screwing action. Alternatively or additionally, glue, epoxy, or other adhesive may be applied on the inner surface of overlap portion 722 and/or the outer surface of second torso member 120, or between the inner surface of overlap portion 722 and/or the outer surface of second torso member 120. Alternatively or additionally, mechanical fastening members (e.g., screws, bolts) may attach overlapping portion 722 to second torso member 120. One or some of these and other attachment methods may be used to change the durability of the connection between the female sleeve 720 and the second torso member 120 as desired.

The extension 724 of the female sleeve 720 may have axially extending ribs (e.g., similar to the ribs 312 of the first end 310 of the sleeve 202). This may provide a snug fit between extension 724 and first torso member 110.

The female sleeve 720 may include a recess 726. The recess 726 may be configured to receive an extension of the anti-rotation member 614. Thus, mating the male sleeve 710 with the female sleeve 720 may limit pivoting of the first torso member 110 relative to the second torso member 120, and vice versa. This is useful in many situations. For example, some artificial trees include internal wiring, and the ends of the respective trunk portions include electrical contacts. The anti-rotation member 614 of the male sleeve 610 and the recess 726 of the female sleeve 720 may serve as an alignment mechanism to align the electrical contacts of the

trunk

110, 120. Further, the anti-rotation member 614 and the recess 726 may prevent subsequent rotation or twisting that may otherwise damage the electrical contacts. To illustrate the inclusion of such internal wiring and electrical contacts, fig. 6A, 7A and 8 show the first and/or

second body portions

110, 120 as transparent to show internal electrical contacts.

Referring to fig. 9-11, an alternative embodiment of a sleeve 202 for facilitating assembly of an artificial tree is shown. The sleeve 202 may have a first end 310 and a second end 320. In an exemplary embodiment, the first end 310 of the sleeve 202 may have a lower edge 940, as shown in FIG. 9. The lower rim 940 may have a width that is substantially equal to a difference between an inner diameter of the first end 310 and an outer diameter of the first end 310. The lower edge 940 may have an angled portion 930. The angled portion 930 of the lower edge 940 may be inclined downward from the longitudinal axis at an angle of less than ninety degrees. In one embodiment, the angled portion 930 may be located at an angle of between approximately thirty and fifty degrees from the longitudinal axis. As shown in fig. 10, the angled portion 930 may include an upper portion 1032, a middle portion 1034, and a lower portion 1036. The lower portion 1036 may be adjacent to the outer protrusion 938 of the sleeve 202. The upper portion 1032 may be opposite the outer protrusion 938.

First end 310 may have an inner diameter substantially equal to the outer diameter of first torso member 110 to allow first end 310 of sleeve 202 to slide over first torso member 110 with minimal space between the inner diameter of first end 310 and the outer diameter of first torso member 110. The second end 320 of the sleeve 202 may have an inner diameter approximately equal to the outer diameter of the second torso member 120. When the inner diameters of first end 310 and second end 320 substantially correspond to the outer diameters of first torso member 110 and second torso member 120, respectively, sleeve 202 may sufficiently interlock first torso member 110 and second torso member 120 to facilitate tree assembly.

In one embodiment, the sleeve 202 may include an outer protrusion 938. Outer tab 938 may be configured to receive an extension of swivel tab 1142 during assembly of the artificial tree, particularly when second torso member 120 is interlocked with first torso member 110. Further, the outer protrusion 938 may traverse the first end 310 and the second end 320 of the sleeve 202 vertically. The outer protrusion 938 may be disposed proximate the lower portion 1032 of the angled portion 930.

Sleeve 202 may be permanently attached to second torso member 120. Permanently attaching may include mechanical fastening means (e.g., screws, bolts). In one embodiment, the permanently attached location may be adjacent the second end 320 of the cannula 202. Alternatively or additionally, glue, epoxy, or other adhesive may be applied between the inner surface of the second end 920 and/or the outer surface of the second torso member 120.

The rotation protrusion 1142 may be provided on the first body part 110. The swivel tab 1142 may extend through the wall of the first torso member 110. The rotation protrusion 1142 may have an extension protruding from the outer wall of the first trunk 110. The extension may extend at a ninety degree angle such that the extension is perpendicular to the outer wall of the first torso member 110. The extension of the swivel tab 1142 may comprise a head. The head may be various shapes including circular, rectangular, pentagonal, and hexagonal. In one embodiment, the head is substantially circular to facilitate rotation of the rotating tab 1142. The head may have a substantially smooth surface to facilitate rotation of the rotating tab 1142. In one embodiment, the extension of the swivel tab 1142 may also include a portion secured to the body of the head. The portion of the body extending from the outer surface of the first trunk 110 may have a substantially cylindrical shape to facilitate the rotation of the rotation protrusion 1142. The body may have a substantially smooth surface that is unthreaded to facilitate rotation of the rotating tab 1142. In one embodiment, the rotation projection may be a screw or a bolt.

The sleeve 202 with the lower edge 940 of the angled portion 930 and the swivel tab 1142 may be used in combination to facilitate assembly of the artificial tree. When the receiving portion 124 of the second torso member 120 receives the extension portion 114 of the first torso member 110, the swivel tabs 1142 may interact with the angled portion 930 of the lower edge 940 at multiple points. In one embodiment, the body of the rotating tab 1142 may first interact with the lower edge 940 of the upper portion 1032 proximate the angled portion 930. Alternatively, the extension of the swivel tab 1142 may first interact with the lower edge 940 of the middle section 1034 or the lower section 1036 proximate the angled section 930. When the second torso member 120 rotates clockwise to accommodate the extension portion 114 of the first torso member 110 in the accommodation portion 124 of the second torso member 120, the gravity applied by the second torso member 120 on the extension portion of the swivel tab 1142 may rotate the swivel tab 1142 clockwise. In conjunction with the clockwise rotation of the swivel tab 1142, the angled portion 930 of the lower edge 940 of the sleeve may guide the receiving portion 124 of the second torso member 120 to fully receive the extension 114 of the first torso member 110. As the second torso member 120 rotates to receive the extension 114 of the first torso member 110, the extension of the rotational tab 1142 may continuously interact with the lower edge 940 along the angled portion 938 such that the extension of the rotational tab may interact with the upper portion 1032, the middle portion 1034, and the lower portion 1036 of the angled portion 930. When the extension of the rotating tab 1142 reaches the outer tab 938 adjacent the lower portion 1036, the extension of the rotating tab 1142 may slide into the interior recess of the outer tab 938. The extension of the swivel tab 1142 may be surrounded by an outer tab 938. The outer protrusion 938 may include an internal ridge or thread that may limit the distance that the extension of the rotation protrusion 1142 slides into the internal recess of the outer protrusion 938. When the extension of the swivel protrusion slides into the interior recess of the outer protrusion 938 of sleeve 202, the receptacle 124 of the second torso member and the extension 114 of the first torso member 110 may be properly aligned together, and thus, the first and

second torso members

110, 120 may be fully interlocked.

The combination of the sleeve 202 with the angled portion 930 on the first end 310 and the clockwise rotation of the rotating tab 1142 may facilitate the assembly of the artificial tree. The angled portion 930 of the first end 310 of the sleeve 202 may dissipate the weight of the second torso member 120. Unlike the flat first end 310 of the sleeve 202, which directs the weight of the second torso member 120 directly downward, the angled first end 310 converts a portion of the weight from directly downward to parallel with the angled portion 930. The downward decreasing force of the weight of second torso member 120 may also result in less friction between swivel tab 1142 and sleeve 202. This reduced friction may also facilitate rotation of second torso member 120 during assembly of the tree.
