DETAILED DESCRIPTION OF THE INVENTION

[0027] FIG. 1 illustrates the elements of the removable handles system in a preferred embodiment of the invention: main removable handle 31, secondary removable handle 61, and cooking vessel side handle 2. FIG. 2 shows the main removable handle 31 attached to one side handle 2 of the cooking vessel 1.

[0028] As illustrated in FIG. 3, in the preferred embodiment of the invention, the cooking vessel side handle has a first end or back plate 2a that is attached to the pot exterior side wall with rivets (not showing) placed through the holes 2e, a second end or upper plate 2c connected to the back plate 2a through the two arms 2b, and two supporting brackets 2d symmetrically located below the upper plate and directly connected to the back plate. The main removable handle is coupled to the side handle 2 through the two notches 2f located in the arms 2b, and the two supporting brackets 2d.

[0029] As illustrated in FIGS. 5-6, the main removable handle comprises the vessel connecting or coupling end 36, the horizontally oriented handgrip 32, and the upwardly oriented handgrip 33. As shown in FIG. 7 the hand grip ends 32 and 33 are connected to the coupling end through the flanged screws 34 and 35, respectively. Each hand grip is intended to be a single component but in FIG. 7 they are split alongside and represented in an exploded fashion in order to visualize the supporting flanged screw that connects each hand grip to the coupling end. As shown in FIG. 8, the main removable handle coupling end includes the main body 37, the cylindrical bar 38, the two mounting bosses 39 with corresponding flanged nuts 40, and a locking mechanism to secure the main removable handle to the cooking vessel side handle. The locking mechanism comprises the shaft 41, the two elbow catches 42, the torsion springs 43 and 44, the release tab 45, the holding plates 46 and 47, and the four screws 48.

[0030] Integrally formed into the main body 37 are the hooks 37a, the arms 37b, and the bridges 37c and 37h. The flanged nuts 40 serve to fasten the mounting bosses 39 to the main body 37, while a square projection at the base of each mounting boss and the square openings 37d and 37h located in the middle of the bridges 37c and 37g, respectively, guarantee that the connections between the mounting bosses 39 and the main body 37 are rigid and do not allow any relative movement or wobbling between these elements. Using the flanged screw 34 the horizontally oriented handgrip 32 is joined to the mounting boss fasten to the bridge 37c while the upwardly oriented handgrip 33 is joined to the mounting boss fasten to the bridge 37g using the flanged screw 35. The openings 37g located in the extremes of the arms 37b allow to receive and rigidly weld the extremes of the cylindrical bar 38.

[0031] The locking mechanism comprises the shaft 41, the two elbow catches 42, the torsion springs 43 and 44, the release tab 45, the holding plates 46 and 47, and the four screws 48. The central shaft 41 includes a central hexagonal section and rounded extremes. In each extreme of the central shaft hexagonal section is welded an elbow catch while the release tab is welded in the middle. The hexagonal shape of the central section facilitates initial placing of the release tab and elbow catches while the rounded extremes allow winding the torsion springs 43 and 44 and pivoting about the notches 37e (only the left notch is shown in FIG. 8) located within the main body 37.

[0032] As shown in FIG. 8, the torsion springs 43 and 44 are wound around the left and right extremes, respectively, of the central shaft. The spring fixed legs, 43a and 44a, rest within the cavities 37f located within the main body 37 (only the left cavity is shown in FIG. 8) while the spring moving legs, 43a and 44a, are received by the orifices 42d drilled throughout the elbow catches 42. The holding plates 46 and 47 and the screws 48 serve to hold in place the spring fixed legs in the abovementioned cavities as well as the extremes of shaft 41 in the notches 37e.

[0033] As illustrated in FIG. 1., the main and secondary removable handles have similar designs and the main difference between the two is the presence of an additional upwardly oriented hand grip in the main removable handle. But both handles share the same horizontally oriented hand grip 32 and similar coupling ends. The coupling end in the secondary removable handle does not include the bridge 37 and for this reason the strips required to hold the locking mechanism in place need to be flat in contrast to the holding strips 46 and 47 from the main removable handle. Besides the above-mentioned features, there are no other differences between the coupling ends of the main and secondary removable handles. Since both coupling ends share the same elements that participate in the attachment operations (hooks 37a, arms 37b with rigidly welded bar 38, and locking mechanism), the main and secondary removable handles are attached and secured to the cooking vessel side handle in the same way.

[0034] The removable handles are attached to a vessel side handle 2 as follows. As shown in FIGS. 9-10, during the initial step of the attachment operation, the removable handle is tilted upwards and brought towards the cooking vessel side handle so that bar 38 rests in the side handle notches 2f, the hooks 37a engage the bottom of the side handle supporting brackets 2d, and the convex surfaces 42a of the elbow catches engage the side handle surface 2g while the torsion springs remain in their relaxed positions. The handle is then rotated downwards about bar 38 and as shown in FIGS. 11-12, in the middle step of the attachment operation the convex surfaces 42b of the elbow catches engage the side handle surface 2h forcing the shaft 41 to rotate counter clockwise and twisting the torsion springs 43 and 44. As shown in FIGS. 13-14, in the final locked position the side handle supporting brackets 2d prevent any further downward rotation of the removable handle about the bar 38 while the torsion springs return to their relaxed positions in which the flat surfaces 42c of the elbow catches are biased toward the lower surface 2i of the side handle upper plate preventing any upward rotation of the handle and hence also preventing the main removable handle from accidentally detaching from the cooking vessel side handle. In the final locked position, any wobbling of the main removable handle is also prevented since the side handle upper plate 2c is tightly abutted by the main removable handle arms 37b while the side handle brackets 2d are tightly abutted by the removable handle hooks 37a.

[0035] The removable handle is automatically or passively locked to the cooking vessel side handle in the final step of the attachment operation. The detachment operation, however, starts with actively unlocking the removable handle from the cooking vessel side handle by pushing the release tab 45 towards the cooking vessel side handle to overcome the opposing forces of the torsion springs and release the elbow catches from below the side handle upper plate. The removable handle is then rotated upwards about the bar 38 and once the main removable handle hooks 37a clear the side handle support brackets 2d the removable handle can be lifted upwards until bar 38 disengages the side handle notches 2f at which stage the detachment operation is complete.

[0036] In a first embodiment, a removable handle assembly for a container having a side wall includes a container handle, a first removable handle, and a locking mechanism. The container handle is for coupling to a side wall of a container. The handle includes a back plate, at least one arm, and at least one supporting bracket.

The at least one supporting bracket extends outwardly from the back plate and is positioned at a height on the back plate that is lower than a height of the at least one arm. The first removable handle is releasably coupled to the container handle and includes a substantially horizontally oriented hand grip member, a support member, a first member, and a second member. The support member is connected to the hand grip member. The first member is connected to the support member for coupling with the at least one supporting bracket. The second member is connected to the support member for seating in the notch of the at least one arm of the container handle. The locking mechanism is coupled to the support member of the first removable handle and automatically secures the first removable handle to the container handle. The locking mechanism includes at least one catch that is non-rotatably coupled to a rotatable shaft. The at least one catch pivots with rotation of the shaft between a locked position and an unlocked position. In the locked position, the at least one catch is positioned under a part of the container handle to deter wobbling or relative movement between the container handle and the first removable handle when the container handle is fixedly attached to a container.

[0037] The first removable handle may include a vertically extending hand grip extending from the support member. The vertically extending hand grip may extend substantially perpendicular to the horizontally oriented hand grip member. The catch may be an elbow catch. The catch may be coupled to a coil spring that exerts a force on the catch when in the locked position to assist in retaining the catch in a locked position. The coil spring may have two end sections, with one end section being connected to the catch and the other end being trapped in the support member. The catch may have a first edge that is convex and a second edge that is L-shaped. The catch may have a mating portion for mating with the shaft. The mating portion of the catch may have an inner hole that has a hexagonal cross-section for seating over the hexagonal cross-section of the inner section of the shaft.

[0038] The removable handle assembly may also include a release member for unlocking the locking mechanism. The release member may be coupled to the shaft of the locking mechanism.

[0039] The container handle may include two arms oppositely disposed and a horizontal plate positioned between the two arms. The horizontal plate may form a lower substantially flat surface for engaging with the at least one catch when in the locked position.

[0040] The first member may be hook shaped and configured to seat in a recess defined in the at least one supporting bracket. The second member may be a horizontally extending bar that extends between opposite sides of the support member. The bar may be sized to seat in the at least one notch in the arm. The bar may be cylindrical in cross-section. The shaft may have an inner section and two outer sections at the outer extents of the shaft. The shaft may have a hexagonal cross-section in the inner section and a circular cross-section at the outer sections, with the shaft being rotatable upon the outer sections.

[0041] The support member of the first removable handle may include a curved upper bracket extending between sides of the support member and a curved rear bracket extending between sides of the support member. The curved rear bracket includes a mounting boss for coupling with the horizontally oriented hand grip member.

[0042] In another embodiment, a removable handle assembly for a container having a side wall includes a container handle, a first removable handle, and a locking mechanism. The container handle is for fixedly coupling to a side wall of a container and includes a back plate, two arms, two supporting brackets, and a horizontal plate. The back plate has a contoured shape for fixing the container handle directly adjacent a side wall of a container. The two arms extend outwardly from the back plate at opposite sides thereof. The arms each have an upwardly facing notch aligned with one another. The two supporting brackets extend outwardly from the back plate at opposite sides thereof and are positioned below the two arms. The horizontal plate is coupled between the two arms above the two supporting brackets. The horizontal plate has a substantially flat lower surface.

[0043] The first removable handle is releasably coupled to the container handle and includes a substantially horizontally oriented hand grip member, a support member, two arms, a horizontal bar, and two hook members. The support member is connected to the hand grip member. The support member has two arms positioned at opposite sides thereof and extends outwardly therefrom. The horizontal bar extends between the arms, with a width between the arms of the first removable handle being wider than a width between the arms of the container handle. The bar seats in the upwardly facing notches of the arms of the container handle. The two hook members extend from the support member and seat under the two supporting brackets of the container handle. The bar and arms of the first removable handle interact with the arms and supporting brackets of the container handle to hold the first removable handle in position on the container handle.

[0044] The locking mechanism is coupled to the support member of the first removable handle and automatically secures the first removable handle to the container handle. The locking mechanism includes two catches that are non-rotatably coupled to a rotatable shaft that is positioned on the support member. The catches pivot with rotation of the shaft between a locked position and an unlocked position. In the locked position, the at least one catch is positioned under the horizontal plate of the container handle to deter wobbling or relative movement between the container handle and the first removable handle.

[0045] Each of the catches may be biased by a spring. The springs may be positioned at opposite ends of the rotatable shaft and trapped between the respective catch member at one end and the support member at the other end.

[0046] The spring may be a coil spring that has two free ends. The catch members may each have a hole for receiving an end of the biasing spring. The support member may have a channel for receiving an opposite end of the biasing spring, with the channel being covered by a holding plate.
