HER/MAIN ER/M/c'fl 36% M Tm HTTDRNEVS United States Patent Ofiice 3,1l5,229 Patented Dec. 24-, 1963 3,115,229 HANDLE CQNSTRUCTIQNS Hermann Erhard, Landauer Strasse 3, Berlin-Wilmersdorf, Germany Filed Dec. 6, H61, Ser. No. 157,504 16 Claims. (Cl. 190-57) This invention relates in general to handle constructions and in particular to a new and useful divided or split handle for suitcases, valises, briefcases, bags and the like, having two half-gripping members which have interengaging means.
Prior to the present invention, it has been known to provide handles including two gripping members which are independently pivotally mounted to permit the carrying of the article by two persons, each grasping a single handle element. In some instances, these handles have been made with their adjacent sides complementary or fiat so that the two gripping elements may be held together by a person using one hand. A disadvantage of such constructions, however, is that the handle elements become easily separated and it is difiicult for a person to hold them together to permit gripping thereof with the elements cooperating as a single handle element. In some instances, push-button fasteners have been provided for such handle elements to facilitate their being secured together when the article to which they are attached is not being carried by two persons. Such devices, however, are rather complicated and expensive.
In accordance with the present invention, there is provided a handle construction which includes two separate handle elements, each of which is pivotally mounted on a supporting arm which in turn is pivotally connected to the article to be carried. The invention includes a construction in which the handle elements each include cooperating side surfaces having complementary gears and recesses thereon defined in directions extending principally longitudinally along the length thereof. The handle elements may be moved together into intermeshing engagement when the elements are to be combined to function as a single handle which may be gripped by one person in one hand.
Accordingly, it is an object of this invention to provide an improved handle construction.
A further object of this invention is to provide a handle having two handle elements independently pivotally lOllIltCd for separate engagement and including intermeshing engageabie portions for combining the elements into a single band gripping unit.
A further object of the invention is to provide a handle having severable handle elements which may be separated for gripping by the adjacent hands of two persons, and which includes engagement means for interconnecting the elements by simply pressing the two members into each other and which may be released by pulling the two ele ments apart.
A further object of the invention is to provide complementary handle elements of a handle gripping unit having facing surfaces with interengaging gear portions defined along the longitudinal length thereof which provide a very large meshing surface to hold the two elements together.
A further object of the invention is to provide a handle construction which is simple in design, rugged in construction and economical to manufacture.
A further object of the invention is to provide a split handle construction which may be manufactured in a single manufacturing step, such as by injection molding or casting.
The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this specification. For a better understanding of the invention, its operating advantages and specific objects obtained by its use, reference should be had to the accompanying drawings and descriptive matter in which there are illustrated and described preferred embodiments of the invention.

FIG. 11 is a partial end perspective view on an enlarged scale of the element indicated in FIG. 9; and
FIG. 12 is a partial end perspective view partially in section of the complementary handle member indicated in FIG. 10.
Referring to the drawings in particular, the invention embodied therein includes a combined or double handle member generally designated 3d which includes two handle elements or members 1 and 2, which are separately and independently rotatably mounted at the outer ends of holding means or supporting arms or straps 3 and 4, respectively. The opposite inner ends of the straps 3 and 4 are rotatable in laterally spaced bearing channels 32, 32 cfined on a bracket member 15 which is secured to an article 16, such as a suitcase, which is adpated to be carried.
In accordance with the invention, as indicated in FIG. 1, the combined handle element 3% is formed when the individual handle elements 1 and 2 are arranged together with interengaging side wall portions in, 2a, respectively, arranged in meshing engagement along the juncture line indicated 19. In the embodiment indicated, the member 1 has, for example, five gear ridges 9 separated by four gear grooves or recesses lltl. Correspondingly, the handle element 2 has a side face 2a with four gear ridges or projection portions 9 which fit into the recesses or grooves in of the element 1. As shown in FIG. 2, the gears are generally designated 11 for the element 1, and 12 for the element 2, and these are defined over the entire length of the side walls 1a and 2a formed on each of the elements l and 2. In some instances, however, it may be desirable that the side walls only include gear formations on a portion thereof.
The handle elements 1 and 2 are rotatably mounted on horizontal portions which extend through openings 5 and d defined on the ends of the elements 1 and 2. As indicated in FIG. 1, the openings 5 and 6 are enlarged as at 7 and 3 adjacent the ends of the elements. The mounting is such that the combined handle unit 3i) may be pivoted from the solid line position indicated in FIG. 1 to either side of the pivot bearing 32, such as to the right side, as indicated in dotted lines in FIG. 1.
In a preferred arrangement according to the invention,
in addition to the horizontal gears 11 and 12, the handle elements 1 and 2 are provided with intermeshing vertical gear and recess 14 and 13, indi ated more clearly in FIGS. 3 to 6. in the embodiment shown, the element 1 is provided with recesses or gaps 13 which are substantially vertical and which are arranged in a position to mesh with projections or gears 14 formed on the element 2 when the two elements are moved together in the position indicated in PEG. 1.
The gear fianks of the horizontal and also of the vertical gearing may extend under a small flank angle indicated a in FIG. 5 for handle elements designated 1 and 2, which may advantageously vary within a magnitude of from 1 to 3. In such a manner, the holding capacity of the grip members may be increased. it should be noted that the teeth may have parallel sides in the manner indicated in PEG. 1, for example. The holding capacity, of course, increases with the number of teeth or gears which are defined on the side face of the complementary elements l and 2.
in accordance with a further feature of the invention, the means for securing or maintaining the meshing engagement of the two handle elements It and 2 is improved by insuring that the distance a between the center lines of the bearings for each of the elements 1 and 2 is made somewhat larger than the distance b between the center lines of the bearings 32 of the bracket 15. In this manner, when the suitcase is carried by the combined handle 3h, both elements and 2 will have a tendency to maintain the meshing engagement between the gearings. The difference between the distances a and b advantageously should correspond about to the height of the teeth engaged.
The end faces 2d of the handle element 1 in the region of the horizontal gearing 11 are advantageously constructed in the form of a terminal abutment 21 against which the gears 1.2 of the member 2 abut on both ends and thereby block any possibility of longitudinal displacement of the handle elements relative to each other.
In those instances where the handle element has a coating or cover 17 such as leather or the like, then the handle elements 1 and Z on both sides of their opposing faces 1a and 2a and along the juncture line 19 have a fiat longitudinal recess 1% so that the line of juncture is somewhat countersunk relative to the surface of the handle member. The edge of the cover or coating 17 as indicated in FIGS. 5 and 6 is folded inwardly about the edge of the longitudinal recess 1% so as to be secure against tearing. The handle elements Ll and 2 are formed to extend with substantially fiat top and bottom surfaces i and curved outer surfaces in relation to the side faces 1a and 2a having the gears defined thereon.
In FIGS. 7l2, a somewhat modified arrangement is indicated, in which two handle elements 1&1 and MP2 are pivotally mounted on stirrups or rods 103 and 1% which in turn are pivotally mounted in bearings 132 on a bracket member 115. in this embodiment, the element 101 is provided with an abutment 121 formed adjacent each end which terminates at a plane separating surface 121a which is parallel to the longitudinal axis of the element lltlll as indicated in PlG. 11. Gear ridges M59 project about to half beyond the separating surface 121a and the tooth grooves lltl extend inwardly from the surface 121a. Each handle portion has the same number of gear ridges, for example, four, wherein the outer gear ridge 109 includes a face which aligns with or is flush with the face of the combined or composite handle 13%? which is formed. The outer groove lllltl is closed by a correspondingly fitting gear 1699'. Thus, a composite handle 136} is formed which includes a flush upper and lower face with rounded ends to permit easy gripping by a persons hand.
Both handle elements in the embodiment indicated in FIGS. 7 to 12 are equal and may be injection molded in a mold from suitable plastic material, for example, or they may be cast.
In the embodiment of FIGS. 7 to 12, as in the embodiment of FIGS. 5 and 6, the flanks of the gears are somewhat inclined so that the teeth have a trapezoidal form. In this manner, the handle members can be more easily removed from the mold after their manufacture and further the holding capacity of the meshing gears is increased and improved. Since both handle members are identical in the FIG. 7-l2 embodiment, only a single mold for the production of the handle members is required.
it will be realized that the gears may be corrugated, if this is desired.
While specific embodiments of the invention have been shown and described in detail to illustrate the application of the inventive principles, it will be understood that the invention may be embodied otherwise without departing from suc principles.
