sum 2 [IF 2 PLASTIC LAY-DOWN HANDLE The present invention relates to a novel handle to be secured to an article to be carried and more particularly to a handle formed of a suitable plastic material which will open out flat when not in use.

Among the objects of the present invention is the provision of a novel handle construction which will open out flat when not in use. The handle includes a central base portion having spaced openings for suitable securing means and oppositely extending gripping portions normally laying flat in the same plane as the base portion. The gripping portions are joined to the base portion by thinner parallel hinge portions defining the longitudinal edges of the base portion.

Another object of the present invention is the provision of a handle construction formed of a suitable plastic material. The

plastic material for the base portion and the gripping portions of the handle is fairly rigid, while the plastic material is grooved to provide thinner hinge portions which are flexible to allow the folding of the gripping portions upward to fon'n a convenient handle to be grasped by the user.

A further object of the present invention is the provision of a plastic handle where the base portion has openings to receive suitable securing or anchoring means, such as rivets, and the openings and fasteners can be covered to enhance the appearance of the handle. One form of covering is a snap-on metal cover, and another form is a contrasting insert received in a recess in the base portion.

Further objects are to provide a construction of maximum simplicity, efficiency, economy and ease of assembly, and such further objects, advantages and capabilities as will later more fully appear and are inherently possessed thereby.

Referring more particularly to the disclosure in the drawings wherein are shown three embodiments of the present invention, FIGS. 1 through 4 disclose one embodiment comprising a lay-down handle 10 adapted to be attached to a case, box, luggage or other object 11 to be carried or transported easily from place to place. The handle 10 is formed of a suitable plastic material, such as polypropylene, which is substantially rigid for the handle, but will be flexible in thinner sections for proper hinging action. The handle is formed as a single integral piece of plastic material having a central base portion 12 and a pair of parallel

handle gripping portions

13,13 separated from the base portion by

parallel hinge portions

14,14.

The base portion 12 is generally rectangular and provided with a pair of spaced

openings

15,15 adjacent the opposite ends thereof for suitable securing means, such as the

rivets

16,16 to secure the base portion onto the case 11. Each handle gripping portion 13 is generally rectangular with outer

rounded corners

17,17 and an elongated opening 18 therein provided with a sinuous or undulated edge 19 to conformably receive the fingers of and enhance the grip of the user. Each hinge 14 is formed by the formation of an elongated groove or channel 21 in the material to provide a substantially thinner flexible portion 22 acting as the hinge. The channel 21 is terminated at each end by an end wall 23, and the channel has an inclined inner side wall 24 adjacent the base portion 12.

To assemble, the case 11 has a pair of openings (not shown) aligned with the

openings

15,15 to receive the

rivets

16,16 and secure the handle to the case 11. In use, the handle is normally in the flat position as shown in FIG. 1. When the object is to be carried, the

gripping portions

13,13 are folded upward about the

hinges

14,14 so that the gripping portions converge from the base portion 12 with the

outer edges

25,25 of the

gripping portions

13,13 in substantially abutting relation (see FIG. 2). The user can then insert the fingers of his hand into the elongated generally aligned openings l8,18. Release of the

gripping portions

13,13 allow the

end walls

23,23 and the inherent memory of the plastic material to return the handle to its opened out position of FIG. 1.

FIGS. 5, 6 and 7 disclose a second embodiment of handle 10 with parts identical to those in the first embodiment having the same numeral with a superscript a. The handle 10" includes a central generally rectangular base portion 12" with spaced openings 15 and a pair of gripping portions 13 joined to the base portion by hinges 14. Each gripping portion 13 has outer rounded corners l7,17 and an elongated opening 18 therein with a sinuous or undulated edge 19", and each hinge 14 is formed by a channel 21" providing a thinner flexible connecting portion and having opposite end walls 23",23" and an inclined side wall 24 adjacent the base portion 12.

At each end of the base portion 12 is formed an elongated indentation 26 adjacent the bottom surface thereof for securement of a metal cover 29. To reinforce the base portion 12 of u the handle 10, a rectangular steel plate 27 is superposed on top of the base portion. The plate 27 has spaced

openings

28,28 aligned with the openings l5,15 of the base portion to receive suitable fasteners, such as rivets l6,16", to secure the handle to an object 11 to be carried. The cover 29 is a generally domed hollow member with depending sides 31 and depending ends 32 formed with inwardly projecting nibs 33 to be projected or snapped into the recesses or indentations 26.

To assemble, the base portion 12 is placed on the object to be carried with the openings 15 aligned with suitable openings (not shown) in the object 11. The reinforcement plate 27 is positioned on the base portion 12 with its openings 28 aligned with the openings 15. Rivets 16 are inserted into the aligned

openings

15 and 28 and secured to the object 11. Then the cover 29 is positioned over the plate 27 and the base portion 12" and pressed or urged downward until the nibs 33 snap into the recesses or indentations 26 to retain the cover on the handle. The cover 29 completely hides and prevents access to the rivets 16 or the reinforcement plate 27. Use of the handle 10 is substantially identical to that described for the first embodiment of handle 10.

FIGS. 8 through 11 disclose a third embodiment of a carrying handle 10" with parts identical to those in the first embodiment having the same numeral with the superscript b. This handle 10 is secured to an object or case 11 to be carried by suitable securing means, such as rivets 116". The handle 10" includes a central generally rectangular base portion 12 having a rectangular recess 34 (FIG. 8 and 11) therein covering a substantial area of the base portion and adapted to receive an inlay or insert 35 (FIGS. 10 and 11) which may be of a contrasting color or texture. The bottom 36 (FIG. 8) of the recess 34 includes the spaced openings 15" for the rivets; each opening being slightly counterbored at 37 (FIG. 10) so that the rivet head fits flush in the recess bottom .36. The inlay or insert 35 may be made of plastic or other suitable material and is secured in the recess by an appropriate adhesive or other suitable means.

Joining the base portion 12 by hinges 14" are a pair of gripping

portions

13,13 which have inclined or converging

end edges

38,38 and a slightly curved. or convex edge 39. Elongated openings 41 are formed in the gripping portions with slightly curved edges and rounded corners. The hinges 14" are formed by generally V-shaped parallel grooves 42 (FIG. 11) extending longitudinally completely along the handle to provide a thinner integral flexible portion of the plastic material.

To assemble, the base portion 12" is positioned on the object 11 to be carried with the openings 15' aligned with like openings (not shown) in the object. The rivets 16 are inserted in the openings 15 with the rivet heads received in the counterbores 37 and fastened to the object 11". The inlay or insert 35 is then suitably affixed in the recess 34 and covers the rivets. The handle is utilized in the same manner as the first two embodiments.

While plastic handles of particular and effective shapes has been shown and described by way of illustration, it is not my intent or desire to unnecessarily restrict the scope or the utility of the improved features by virtue of these illustrative embodiments.
