The present invention relates to a handheld lifting device, and more particularly to a handheld lifting device with a pair of hooks and a handle attached to one of the hooks for temporary use when lifting a container.
Handheld lifting devices have long been used for lifting containers during transport as well as to assist a user in pouring contents from the container. For example, a standard five-gallon (5 gal.) bucket is designed to store, transport, and carry a product, often a liquid. The standard bucket typically includes a single U-shaped handle rotatably connected to the top section of the bucket on opposite sides of the bucket. Other versions of handles include a thick plastic strap with an integrated handle section. Generally, the rotating ends of the top handle create a pivot axis that extends through the sides of the bucket which allows a user to grab the gripping section, rotate the handle upwards and carry the bucket from above. Although these top hangers effectively allow the buckets to be carried, they are not very helpful to users when they want to tilt and pour the contents from buckets.
When these buckets are filled with typical liquids sold in these containers, such as paints, oils, lubricants, sealants, cleaners, and laundry detergents, they can weigh between forty to sixty pounds (40 lb.-60 lb.). When the user wants to pour the contents from the bucket, some manufacturers suggest placing the bucket on a table and laying the bucket on its side with the pouring spout at the twelve o'clock position; as the bucket is rotated and the pouring spout moves away from the twelve o'clock position, the liquid contained inside the bucket begins to pour out from the spout. A table or other elevated platform is not always available to help with pouring the contents from the bucket, and rotating the bucket on the ground is not satisfactory if the contents need to be poured into a hopper or other receptacle that is elevated above the ground. Similarly, tilting an upright bucket with one edge resting on the table or the ground is also not always an option.
Since the bottom of these buckets typically only have a ⅜″ lip that make it hard for the user to grasp with their fingertips, it is difficult for users to lift and pour one of these large buckets, especially when it is full. Accordingly, there have been a number of inventions over the years which provide the user with a handheld lifting device with a handle at the bottom end of the bucket or on the side of the bucket which can help the user in lifting and pouring the contents from the container. Some of these known devices allow the user to connect a removable handle to the bucket, such as disclosed in U.S. Pat. Nos. 7,399,017, 7,284,777, 5,255,947, and 4,116,374 and in U.S. Des. Pat. Nos. D927,186, D704,937 and D581,162, and some large buckets are even produced with an integral bottom handle, such as disclosed in U.S. Pat. Nos. 10,450,105 and 9,856,052. Some of the removable lifting devices with handles are collapsible for easy storage, such as the '162 patent, the '937 patent, the '374 patent, and the '947 patent, but they only wrap around the circumference of the container and could slip off the bottom. Other removable lifting devices with handles engage the base of the bucket to more securely hold the container and help prevent the device from slipping off of the container, such as disclosed in the '017 patent and the '777 patent, but they are not collapsible. The handheld lifting device disclosed in the '186 patent is both collapsible and securely holds the container at both the top and at the bottom; however, this device requires a pair of straps that circumferentially wrap around the container on opposite sides of the handle.
It would be beneficial to provide a handheld lifting device that is collapsible and securely holds the container at both the top and at the bottom and which does not require any straps wrapping circumferentially around the container.
The handheld lifting device has a longitudinally extending body with hooks on opposite ends that respectively engage the top rim and the bottom lip of the container, such as a five-gallon (5 gal.) bucket, and the lower hook has a handle extending outward, away from the container. The longitudinally extending body has a fixed length section and a variable length section which are connected by a fastener which can shorten the variable length section and thereby pull the hooks toward each other from a loosened configuration to a tightened configuration. In the loosened configuration, the user can easily place the hooks onto the top rim and bottom lip and remove the hooks therefrom. In the tightened configuration, the handheld lifting device is securely mounted to the container, and the handle can be used to help lift the container and tilt the container for pouring out its contents.
In one aspect of the handheld lifting device, the handle is formed with sidewalls that extend outward from the lower hook, and the longitudinally extending body is formed by flexible straps that are collapsible and can be placed within the handle when the upper hook is removed from the container.
In another aspect of the present invention, one of the sidewalls for the handle has a notch in which the upper hook nests.
Further areas of applicability of the present invention will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
The present invention will become more fully understood from the detailed description and the accompanying drawings, wherein:
The following description of the preferred embodiment(s) is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.
The handheld lifting device 10 as shown in the drawings and described herein provides a temporary handle designed for use with a container 100, such as a bucket, that allows a user to have a secure grip on the bottom of the bucket to provide better pouring control and results in reduced fatigue in the user's fingers when gripping the bucket and pouring the contents from the bucket. The handheld lifting device generally includes a longitudinally extending body 12 that has an upper end 24, a lower end 26, a fixed length section 28 extending to one of the upper end and the lower end, and a variable length section 30 connected to the fixed length section and extending to the other of the upper end and the lower end. The upper end and the lower end are spaced by an extended distance (DE) in a loosened configuration of the variable length section as shown in
An upper hook 14 is fixedly attached to the upper end of the longitudinally extending body, and a handle 16 is fixedly attached to the lower end of the longitudinally extending body. The upper hook has a shank 70 extending to the head 86 of the hook. The handle has a grip 18 and a lower hook 20 attached to the grip. When the variable length section is in the loosened configuration, the upper hook and the lower hook releasably connect to the top rim 110 and the bottom lip 120 of the container, respectively. A fastener 22 operatively connects the variable length section to the fixed length section. The fastener adjusts the length of the variable length section so the upper hook and the lower hook can respectively clamp onto the top rim of the container and the bottom lip of the container in the tightened configuration and can respectively release from the top rim of the container and the bottom lip of the container in the loosened configuration.
The preferred embodiment of the handheld lifting device is shown in
As respectively shown in
The handle has a pair of sidewalls 50 posteriorly extending from the lower hook to opposite ends of the grip 18a, 18b. The lower hook has a sidewall shank 52 that laterally extends between the handle's sidewalls and longitudinally extends from the head 54 of the lower hook to its distal end 56. The distal end of the sidewall shank has an aperture 58 that is spaced a longitudinal distance (DL) away from the head of the lower hook, and the grip is spaced a posterior distance (DP) away from the aperture and is also spaced the longitudinal distance away from the head of the lower hook. Preferably, the longitudinal distance is greater than the posterior distance (DL>DP). The exterior side 78 of the sidewall shank has a concave arc shape 80, and the head extends anteriorly away from the exterior side of the sidewall shank. The lower hook has a series of prongs 82 that extend longitudinally from its head and form an arc-shaped groove 84 between the sidewall shank and the series of prongs.
Details of the handle with the upper hook in its nested arrangement are described below with reference to
The lower end of the variable length strap section is fixedly attached to the handle at the aperture in the distal end of the sidewall shank. Preferably, a pair of laterally spaced legs 62 extend from an interior side 64 of the sidewall shank to a platform 60, and the aperture extends longitudinally between the laterally spaced legs, the interior side of the sidewall shank, and the platform's underside 66. One portion 46a of the variable length strap section's fixed end passes through the aperture and another portion 46b of the fixed end wraps around the platform's topside 68 and is sewn to the strap section extending between the cam buckle and the aperture so the fixed end is fixedly attached to the platform.
An alternative embodiment of the handheld lifting device is shown in
In this alternative embodiment, the handle has a “D” loop shape that is ½″ wide with a contoured comfort grip 98 that is connected by sidewalls to its base section. The base section is securely fastened to the end of the lower hook's shank which is approximately 2″ from its bottom bend. The grip is spaced posteriorly away from the shank by a distance approximately equal to the longitudinal distance (DL) to the bottom bend, i.e., approximately 2″, to provide enough clearance for the user to grasp the grip when it is attached to the bottom of the bucket. The “D” shaped grip is ½″wide, and the “D” shaped grip and the hooks can be made from ⅛″ aluminum flat stock but could be made from other materials having other dimensions without departing from the inventive aspects described herein.
In yet another alternative embodiment, a rigid bar and a ratchet mechanism can be used for the longitudinally extending body and fastener, respectively, rather than using the flexible strap and buckle. An example of a rigid bar and ratchet mechanism is disclosed in U.S. Pat. No. 8,177,203 which is incorporated by reference. One hook is fixedly attached to the fixed handle which has the ratchet, and the other hook is attached to the distal end of the rigid bar. The trigger portion of the ratchet is depressed to pull the proximal end of the bar further into the handle, thereby causing the hook on its distal end to move closer to the hook attached to the handle. The ratchet can be released to allow the bar to slide back out from the ratchet, increasing the distance between the hook on the bar's distal and the hook attached to the handle, thereby allowing the hooks to be removed from their respective mounting positions on the container.
Regardless of the embodiment, the handheld lifting device improves on existing handles wherein products in the prior art that have a rigid handle attachment are larger in size, limiting storage and transport when not in use. These products are more cumbersome to attach and do not allow for one handed attachment, which is possible with either a rigid or pliable handheld lifting device because the handle vertically attaches to the container with the hooks being connected independently of each other, and the fastener subsequently longitudinally extending body in its tightened configuration when the hooks are connected to the top rim and bottom lip.
Although the handheld lifting device described herein is optimized for operation with a five gallon (5 gal.) bucket, it will be appreciated that the device can be used with many types of containers that can have a range of heights and diameters and may even have different cross-sectional shapes. The containers do not necessarily require a lid because the upper hook can be secured over the rim of the bucket. The containers preferably have a lip around their bottom to secure the lower hook. Accordingly, the size, shape, and circumference of the container is not intended to be limiting since the handle attaches vertically and not around the circumference of the container.
The embodiments were chosen and described to best explain the principles of the invention and its practical application to persons who are skilled in the art. As various modifications could be made to the exemplary embodiments, as described above with reference to the corresponding illustrations, without departing from the scope of the invention, it is intended that all matter contained in the foregoing description and shown in the accompanying drawings shall be interpreted as illustrative rather than limiting. For example, the buckle could be a simple loop or ring while the flexible strap could have hook and loop fasteners to keep the strap taut in the tightened configuration, such as disclosed in U.S. Pat. No. 7,284,777 which is incorporated by reference herein. Also, the cam buckle could be spring-loaded or a locking cam. It will also be appreciated that, in yet another embodiment of the invention, the hook at the top of the bucket could have a handle similar to the hook and handle described above for the bottom of the bucket, and this version of the handheld lifting device would be beneficial for those buckets that do not have a U-shaped handle or any other handle at the top. Thus, the breadth and scope of the present invention should not be limited by any of the above-described exemplary embodiments, but should be defined only in accordance with the following claims appended hereto and their equivalents.
This application claims priority from U.S. Provisional Patent Application No. 63/435,374 filed on Dec. 27, 2022 which is herein incorporated in its entirety.
