Definitions
- the present invention relates to luggage cases, and in particular to a lower pull handle integrated with the shell of luggage cases.
- Many luggage cases often include both a carry handle and an extendable pull handle.
- a user typically lifts the luggage by the carry handle, and guides or tows the luggage with the extended pull handle.
- the extendable portion of the pull handles collapse into a lower portion of the pull handle.
- These two portions of the pull handle are sometimes attached to the framework or the shell of the luggage cases.
- This design relies on multiple handle components and assembly, which includes high costs associated with manufacturing the luggage case.
- the lower tubular handle section is visible on the exterior of the luggage case.
- the exterior handle decreases the visual appeal of the luggage case and can increase the likely hood of failure or interfering with the nearby environment.

- the two protrusions 36a, b may be slid into the lower tubular handle section 50 longitudinally, with the first locating protrusion 36a entering the lower tubular handle section 50 first, and the second locating protrusion 36b following.
- the protrusions may be slide into the lower tubular handle section 50 without engaging one another's respective apertures. In various examples, this may be accomplished by sizing the protrusions and apertures differently.
- the first protrusion 36a may be a larger size than the second protrusion 36b.
- protrusion 36a may avoid engaging with the wrong aperture (e.g. 54b), which it encounters first, but passes easily, because the wrong aperture may be a smaller size than protrusion 36a.

Opposing sliding support surfaces 59 may also be parallel even if the projecting surface 55 and the rear panel 12 are not. In various embodiment's, the sliding support surfaces may protrude from their base surfaces (i.e. side walls, rear panel, or projecting surface) and may hold tighter tolerances to their opposing surfaces than the base surface. These tighter tolerances may allow better fitment of the tubular member 24 or the guide collar 40 within the lower tubular handle section 50.
- the parallel surface may allow smooth sliding of the tubular member 24 or the guide collar 40 within the lower tubular handle section 50.
- a plurality of structural elements may be formed within the lower tubular handle section 50.
- the plurality of structural elements aid in locating other elements or they may provide strength to the lower tubular handle section 50.

- the lower tubular handle section 50 may be sufficiently flexible such that as the top bracket insert 30 is inserted into the lower tubular handle section 50, the wall of the handle section 50 positioned proximal to the interior of the luggage case 5 may flex allowing the protrusions to slide along the longitudinal length of the lower tubular handle section 50. Once the protrusions 36 reach the correct aperture 54a or b the wall of the lower tubular handle section 50 may return to an un-flexed state and snap the aperture 54 a or b over the protrusion 36 a or b. While two protrusions are discussed here, it is to be understood that only one protrusion may be used or more than two protrusions may be used.

- Releasing the button 27 actuates the engagement mechanism 21 to cause the engagement member 26 to be received in an aperture 52 with which it is aligned to secure the relative positions of the extendable tubes.
- Examples of relative positions contemplated herein include a fully retracted position without any extension, a slightly extended carry position, and/or at least one fully extended guide position.
- the lower tubular handle section 50 may include a first aperture 52a for receiving the engagement member 26 when the extendable handle assembly 20 is a fully retracted position.
- the lower tubular handle section 50 may also include a second aperture 52b for receiving the engagement member 26 to lengthen the extendable handle assembly 20 by a small amount to the carry position.
- the button 27 is actuated to extract the engagement member 26 from the first aperture 52a.
- the lower tubular handle section 50 may also include a third aperture for receiving the engagement member 26 to lengthen the extendable handle assembly 20 by a larger amount, past the carry position to a fully extended position. There may be more than one position longer than the carry position.
- the lower tubular handle section 50 may include any number of adjustment apertures.
- a guide collar 40 is coupled to the lower end of tube member 24.
- one end of the guide collar 40 may include a protrusion 48 that corresponds to the interior of the tubular member 24.
- the guide collar 40 prevents or limits the tubular member 24 from contacting the walls of the lower tubular handle section 50.
- the body of the guide collar 40 acts as a spacer and bearing surface between the tubular member 24 and the lower tubular handle section 50 during relative movement.
- the guide collar 40 may also incorporate a portion of the engagement mechanism 21, as well as house parts of the engagement mechanism 21, e.g. the engagement member 26, that is used in securing the tubular member 24 relative to the lower tubular handle section 50, as described herein.
- the guide defines a passage 42 which provides a space for the engagement mechanism 21 to pass through the guide collar 40.
- the engagement mechanism 21 may include and actuator button 27 supported by a return spring 28a.
- the button 27 may move a linkage 29 that is operable to move a slide 25.
- the slide 25 may also have a return spring 28b.
- the slide 25 may be in contact with engagement member 26. Movement of the slide 25 may release the engagement member 26 from aperture 52 as variously illustrated.
- the guide collar 40 may include a plurality of walls 44, 45, 46, and 47 which are contact the walls of the lower tubular handle section 50.
- these walls 44, 45, 46, and 47 contact and ride along support surfaces 57 and 59 discussed above.
- These support surfaces 57 and 59 extend along the lower tubular handle section 50 to be engaged with the guide collar 40 when the tubular member 24 is adjusted between the fully retracted position, the carry position, and up to just the fully extended position.
- the engagement of the support surfaces 57 and 59 shown for example in Fig. 4B , form an alignment mechanism which keeps the guide collar 40, and thus the tubular member 24, from rotating relative to the lower tubular handle section 50 and allows smooth sliding of both.
- the engagement mechanism noted above may be utilized to secure the tubular member 24 in a position relative to the lower tubular handle section 50 by causing the engagement member 26 to be received in the first, second, or third aperture 52a, 52b, or 52c formed at desired positions along the lower tubular handle section 50.
- the engagement mechanism 21 may selectively engage any additional aperture along the longitudinal length.
- the engagement member 26 may directly engage the apertures 52a, 52b, or 52c.
- the engagement member 26 may not directly engage the apertures 52a, 52b, or 52c.
- one or more of the apertures 52a, 52b, or 52c may support an engagement member receiver 60.
- Each aperture may engage with a receiver 60.
- the receiver 60 may be a plastic (or other material) tab that snaps into each of the apertures.
- the receiver 60 may have a recess that is sized to match the engagement member 26.
- the integration of the various components of the luggage case 5 may allow for reduced costs associated with assembly, as well as weight savings, as well as enhanced strength and durability.
- the integration of the lower tubular handle section 50 is an example of this.
- the grip portion 22 with the tubular member 24 may be integrated, or the tubular member 24 with the guide collar.
- the grip portion 22 and tubular member 24 may be fabricated in such a way as to allow the button 27 and related mechanisms 21, such as a wire or linkage 29, to be received within the handgrip and tubular member 24 and still be allowed to operate as necessary to actuate the engagement mechanism as noted above.
- the grip portion and tubular member 24 may be formed continuously or separately. They may be formed of a fiber reinforced plastic as this material may provide sufficient strength and stiffness. Also, since carbon fibers are lighter than aluminum, the total weight of the handle assembly 20 may be lighter than the total weight of a conventional plastic grip portion 22 and the aluminum tubular member 24. However, in various other examples, the grip portion 22 may be formed of another material, such as metal, reinforced plastic, plastic, wood, or other materials having sufficient strength and stiffness.
- the tubular member 24 may or may not be formed of the same material, and may be a separate member suitably attached to the grip portion 22. In various examples, a thermoplastic reinforced with carbon fibers may be used to integrally fabricate the grip portion 22 and the tubular member 24.
- the thermoplastic may be a single plastic such as polyamide or a polymer blend.
- the thermoplastic is a matrix that embeds the continuous carbon fibers to provide the composite with impact resistance or toughness.
- the method includes laying up the carbon fibers, and molding the thermoplastic with the carbon fibers to form an integrated composite component.
- any of a variety of material that may be used to form the various components any of a variety of manufacturing processes may be used as well. For example, manufacturing may include injection molding or compression molding, among other processes.
- the luggage case 5 may be manufactured through injection molding process utilizing any known appropriate materials.
- an injection molding tool 100 may be utilized to form the luggage case 5.
- the injection-moulding tool may include a top tool portion 70, a bottom tool portion 80, and a slide tool portion 90.
- the top tool portion 70 and the bottom tool portion 80 may mate together leaving a gap that forms the plurality of panels that define the luggage case 5.
- the slide tool portion 90 may be inserted within the top tool portion 80 and the bottom tool portion 90 to form the lower tubular handle section 50 integrally into rear panel 12 of the luggage case 5.
- the gap between tool 70 and slide 90 may define the walls of the lower tubular handle section 50.
- the tool 70 and the slide 90 may contact at a plurality of points 92 forming apertures through the lower tubular handle section 50.
- aperture 52 may be formed by contacting tool 70 with slide 90.
- Slide 90 may have an engagement lock 94 that also engages tool 70 forming an end aperture 58 in the lower tubular handle section 50.
- the engagement lock 94 between the tools may improve the consistency of the formation of the lower tubular handle section during the injection molding process.
- the handle assembly 20 including an integrally formed lower handle section and a slidable handle section, provides a luggage case that includes fewer parts than typical luggage cases.
- the integrally moulded tube of the handle provides dual function replacing the usual outer tube of a typical pull handle arrangement.
- integrally moulded part as the outer tube of the handle assembly (i.e. receives the sliding tube in its interior), it is lighter and avoids need for an additional tube (e.g. and aluminium tube attached to the shell), which is more costly than the integrally moulded lower handle section (e.g. which can be part of the plastic injection moulding of the shell).
- This arrangement reduces parts costs and simplifies manufacturing further reducing costs to construct the luggage case.
- the handle assembly 20 also includes features which simplify assembly.
- snap-fit features which allow simple engagement between movable components, and/or the integrally formed lower handle section for replacing that portion of a typical extendable handle.
- the integral handle section is contiguous with the luggage case shell, the integral form provides better visual appearance.
- the lower handle section is integrally formed it is able to provide better protection of the other movable handle tubes since they are not exposed to the interior of the luggage case and are not reliant on fasteners or brackets to attach them to the luggage case.
- the top bracket insert may provide stiffness to prevent bending and local reinforcement which may make the handle assembly more robust during heavy usage of the luggage case by a user.
