Abstract
The handle assembly comprises a stationary bracket (12) which mounts to a container wall (14) and a movable handle (16) pivotally connected to the bracket (12). The bracket is formed with an inner portion that is rotatably engaging with a pair of pivoting arms extending from the movable handle so that the lightweight handle may easily be assembl ed and disassembled. Each of the pivoting arms (28, 30) is formed with a movable stop member (22, 24) which is advantageously positione d to contact and bear against stationary stop members which are attached. The stationary stop members and movable stop members (22, 24) each have a substantially planar contact surface which is designed such that when the movable handle is pivoted to the lifting/operati ve position, the movable stop members are in contact with the at least one stationary stop member with less stress in the materials than i n conventional handles.

~F'~lL1 j BUG j~g9 With reference to FIGURE 7, the rotating pivot portions 32 and 34 comprise cylindrical portions 36 and 38, respectively, which are adapted to freely rotate within corresponding cylindrically shaped cavity portions 40 and 42 (FIGURE 8) extending inwardly from a rear surface 44 of the stationary bracket 12. Cylindrical portions 36 and 38 are captured within the first and second cavity portions 40 and 42 when bracket 12 is fastened to container wall 14. When the movable handle I6 is in its operative position (FIGURE 6), the cylindrical portions 36 and 38 are in bearing contact with their corresponding cavity portions 40 and 42.
Still referring to FIGURE 7, each of the rotating pivot portions 32 and 34 further comprise a semi-circularly shaped flange portion 50 protruding from respective ends of _. the cylindrical portions 36 and 38 which are adapted to freely rotate within corresponding cylindrically shaped cavity portions 52 which extend inwardly from the rear surface 44 of the stationary bracket 12. When the flange portions 50 are disposed within the cavity portions 52, the axial movement of the cylindrical portions 36 and 38 a«d therefore the handle is limited.
The rotating pivot portion 34 further comprises a spring support 56 disposed adjacent to and extending from the cylindrical portion 38. The spring support portion 56 is of generally cylindrical shape and is adapted to receive a torsion spring 58 (FIGURE 4). The spring support portion 56 is rotatable within a spring attachment cavity 60 extending inward from the rear surface 44 of the stationary bracket 12. The spring support 56 further includes a rounded square section 62 that is adapted to secure __ one end of the torsion spring 58 which has been wound around a square mandrel to produce square spring tang 59. The spring and spring support 56 have been selected to ~0 reduce stress in the parts thereby creating a longer lifespan for those parts. Where prior art torsion springs have been engaged in a slot in the part around which they are disposed the slotted material tends to fracture from use. Since the square section 62 is inherCntly of a thicker cross section, it is better able to handle the stress. The stress is also divided over four corners as opposed to two as in the stated prior art arrangements.
The other end of the torsion spring 58 is secured by spring leg 57 receivable within a channel 64 4AIIFIVtt'1~t"1 ~''.~-!~'--r ~'L'~'ll~S 9 9 / 0 0 2 ~+ 4 ~'E~'~ 1 ~ p.UG 1999 -g-benefit of the invention will be retained. Preferably, the range of angles for the contact surfaces should be about 38° to about 52° to the container wall with a more preferred range of about 42° to about 48°. It will be understood by one of ordinary skill in the art, subsequent to exposure to this disclosure, that the force advantage of the present invention deteriorates in each direction of angle when moving away from the optimum of about 45°. Referring to FIGURE 11, one example of the invention is provided with measurements taken and forces shown. The calculations set forth hereunder demonstrate the very low pivot and stop forces associated with the handle of the invention. The formulae are intended to be read in conjunction with FIGURE 11:

The stationary bracket 12 and the movable handle 16 may be made from a _, variety of materials, including but not limited to, polyethylene or any high strength thermoplastic material. The handles of the invention uniquely may be made of polyethylene which if used in a configuration not adhering to the parameters of the invention is generally not structurally strong enough to act as a functional handle. To realize additional weight reductions and to reduce material costs and molding time, material from the stationary bracket 12 and the movable handle 16 may be removed in various places without significantly reducing the load/strength requirements of the components.

Similarly, the hand grip 26 may be formed with a hollow inner portion 80 thereby also removing a significant amount of material, as illustrated in FIGURE 9, which is a cross section taken along section line 9-9 of FIGURE 4.
Except for the torsion spring 58, protuberance on the container and mounting bolts (not shown), all of features of the handle assembly 10 heretofore described are formed integral to either the stationary bracket 12 or the movable handle 16.
(Stationary stop members other than those molded as part of the container are additional structures).
This feature provides a handle assembly 10 that is compatible with high production environments and which is reliable and durable. The stationary bracket 12 and the .....~, movable handle 16 may be manufactured by conventional molding processes suitable for use with thermoplastic materials.
While preferred embodiments have been shown and described, various modifications and substitutions may be made thereto without departing from the spirit and scope of the invention. Accordingly, it is to be understood hat the present invention has been described by way of illustration and not limitation.
