Cl. 16--115 8 Claims ABSTRACT OF THE DISCLOSURE A collapsible handle for a carrying case, luggage and the like in which the linkage pivotally connecting the handgrip to the case wall is urged selectively by leaf springs into a raised carrying position and a toggled collapsed position with the lower surface of the handgrip against or adjacent the case wall.

This is a continuation-in-part of my copending application Ser. No. 630,389 filed April 12, 1967.

This invention relates to a handle for use with a carrying case, luggage and the like which is collapsible from a raised carrying position to a non-carrying position in which the lower or undersurface of the handgrip is against or adjacent the case wall.

The primary object of the invention is to provide a collapsible handle of the character described in which leaf springs are used in conjunction with pivoted linkage connecting the handgrip to the case Wall whereby the springs constantly urge the handgrip selectively into the raised carrying position above the case wall and into the collapsed non-carrying position against or adjacent the case wall, the leaf springs acting cooperatively with the pivot points of the linkage to provide toggle retention of the handgrip in its collapsed non-carrying position.

Another object of the invention is to provide a collapsible handle of the character described which is raised from its collapsed non-carrying position by depressing one end of the handgrip to raise the other end and then by releasing the depressed end, there being stop means to prevent overturning of the handgrip in the process of raising the same.

Another object of the invention is to provide a collapsible handle of the character described which is sturdy and therefore capable of sustaining substantial loads while it is relatively simple in construction and economical to assemble and mount on a carrying case, as well as easy to raise and collapse.

These and other objects of the invention will become more apparent as the following description proceeds in conjunction with the accompanying drawings wherein:

FIG. 1 is a side elevational view of the instant handle shown in its collapsed non-carrying position, parts being broken away and shown in section;

FIG. 2 is a view similar to FIG. 1 showing the handle in its raised carrying position;

FIG. 3 is a sectional view taken on the line 3-3 of FIG. 1; and

FIG. 4 is a perspective view of a modified form of link.

Specific reference is now being made to the drawings wherein similar reference characters are used for corresponding elements throughout.

The instant handle comprises three essential components, namely an elongated handgrip l0, anchoring members 12 and linkage 14 operatively connecting the handgrip to the anchoring members. The handgrip may be made of a suitable material, preferably molded of plastic, and includes recesses 16 adjacent the ends 18 and 20, the recesses opening through the lower or undersurface 22 of the handgrip. The ends 18 and 20 are tapered downwardly and inwardly as at 24 to meet the lower substantially flat surface 22 at-corners 26.

The recess 16 contains an upper wall 28, side walls 30 and inner and outer end portions 32 and 34. Opening into the recess through the opposed side walls 30 are terminally closed upwardly and inwardly inclined slots 36.

Each anchoring member 12 includes a metallic substantially U-shaped member having upstanding ears 38 joined by a web 40 which bears against the case wall 42 and is secured thereto by an appropriate staked-in screw 44 and nut 46. To prevent rotation of the member while the nut 46 is screwed home, the web 42 can be provided with an inward extension 48 having a downturned lug or hook which fits into an appropriate aperture in the case wall.

In the form of the invention shown in FIGS. l-3, the linkage 14 comprises a pair of elongated vertical transversely spaced plates 50 and 52. A first transverse pin 56 extends rotatably through the plates adjacent their inner ends and include end portions 58 which extend into the slots 36 for sliding movement therealong. Thus the inner end of each link unit is slidable lengthwise of the handgrip and pivotal around a transverse axis. Adjacent the other or outer ends of the plates, another or second transverse pin 60 extends rotatably through the plates, the pin being preferably a double headed rivet carried by the anchoring member 12 and extending between the ears 38 thereof. Thus the outer end of each link unit is pivoted to the anchoring member around a transverse axis.

Secured between the plates 50 and 52 intermediate the first and second pivot pins 56 and '60 is a third fixed pin 62 and secured between the ears 38 beneath the second pivot pin 60 is another or fourth fixed pin 64. A leaf spring 66 is provided which is disposed between the plates 50 and 52, straddles the second pivot pin 60 and is terminally hooked as at 68 and 70 around the pins 62 and 64, the leaf spring being under tension at all times tending thereby to draw the terminal pins 62 and 64 towards each other.

The outer end portions of the plates 50 and 52 are cut away inwardly beyond the area of the pin '64 but short of the pivot pin 60 as at 72 so that the plates, in eflect, contain longitudinal extensions 74 for a purpose soon to appear. In this form of the invention each link is a channel so that the plates 50 and 52 at their lower edges are joined by a web 76 which extends partially of the length of the plates up to their inner edges.

In the modification shown in FIG. 4, the link is not a pre-formed channel member but rather a pair of vertically disposed transversely spaced plates 78 and 80 which are held together by modified forms of the third fixed pin and first pivot pin. Thus the third fixed pin includes an enlarged central spacer portion 82 and reduced pintles 84 which extend through the plates and are then peened or headed as at 86 with the result that the shoulders 88 formed at the juncture of the pintles and the spacer portion 82 bear against the inner faces of the plates. Similarly, the first pivot pin has a central enlarged spacer portion 90 and reduced pintles 92 which extend through the plates and are slidably and rotatably received in the handgrip slots 36. The pintles are peened as at 94 at the outer faces of the plates to retain the pivot pin on the plates. Aligned holes 95 are provided in the plates to rotatably receive the second pivot pin 60 and instead of rectangular cut-outs 72 which clear the fourth pin 64 and form the extensions 74 as in FIGS. 1-3, the extensions in this form of the invention are formed as angular undercuts 96 at the extreme outer ends of the plates 78 and 80, preferably employing at 45 angle.

In use when the handle is in its collapsed position as shown in FIG. 1, its lower surface 22 is against the case wall 42 and each of the links 12 is in a generally horizontal slightly inclined position with the first pivot pin 56 or 90 adjacent the outer end 98 of the slots 36. The pin 56 is below the horizontal line 100 joining the second pivot pins 60 so that a toggle action takes place. The third fixed pin 62 or 82 also assumes a position below line 100 so that the spring 66, being under tension at all times, aids this toggle action. When finger pressure is applied to one end of the handgrip, say end 20, the hand grip rocks around the corresponding corner 26 to raise the other end 18. At that end the pin 56 moves towards the outer end 98 of the slots 36, the link being urged into this raised position by the spring 66 until the extensions 74 or 96 abuts the fourth pin 64 thus preventing the handgrip from overturning or rattling. It will be noted that the extension 74 or 96 at the outer end of the link units in both modifications are separated laterally to allow clearance for the spring 66.

As the end 18 is first raised, the toggle at the other end 20 is broken and the first pivot pin 56 or 90 moves above the line 100. When the finger pressure on the end 20 is released, the spring 66 at that end urges the link upwardly until its extension 74 or 96 abuts the corresponding pin 64, at which position the handgrip is in its raised position substantially parallel to the case wall.

The foregoing operation employs a rocking action around either of the corners 26 of the handgrip. If desired, the ears 38 of the anchoring members 12 can be made of such height as to engage the upper wall 28 of the recess 16 when the handle is in its non-carrying collapsed position, wherein the lower surface 22 of the handgrip is adjacent but does not abut the case wall 42. In this construction, a push downwardly on one of the ends of the handgrip in this position will cause that end to rock around the fulcrum formed by the cars 38 engaging the upper wall 28 of the recess 16, rather than around the corner 26, as described above.

While preferred embodiments of the invention have been here shown and described, it will be understood that skilled artisans may make minor variations without departing from the spirit of the invention.
