This invention is related to carrying devices that aid in the physical engagement or lifting and transporting dimensionally large unyieldly objects such as material panels.
Prior art devices of this type have been developed to allow for lifting and moving large objects by hand, see for example U.S. Pat. Nos. 4,113,160, 6,102,462, Design Patents D317,703, D423,309.
In U.S. Pat. No. 4,113,160 a sheet sling can be seen having a pair of identical elongated material engagement elements adjustably secured to one another for selective reversal edge engagement of a sheet to be transported.
U.S. Pat. No. 6,102,462 illustrates a mattress and sheet material carrying apparatus having a main strap with a pair of dependent load support strap members extending therefrom allowing two individuals to group oppositely disposed strap ends and lift the material load between them.
U.S. Pat. No. 8,251,421 claims a panel carrier having a flexible shape with an attached rigid handle secured to a contoured U-shaped panel receiving platform.
U.S. Design Patent D317,703 discloses an ornamental design for a drywall carrier having a rigid handle with an eccentric extending shaft and a spade like end defining a material engagement lip there along.
U.S. Design Patent D423,309 claims an ornamental design for a handle for carrying wall board having a flexible cord and attached grip with a material engagement element attached to its oppositely disposed end.
A handle enabled carrying device having a panel receiving end element and a flexible lifting strap with an adjustable handle thereon. A panel engagement body member has a panel receiving platform with oppositely disposed impact positioning portion and vertically spaced, oppositely disposed extending impact engagement release elements to assist in removing the device from engagement with the panel. A centralized apertured lifting tab is formed in a vertically offset orientation on the body member to accommodate panel positioning and from which the flexible lifting strap extends with the handle which is adjustable on the strap to afford angular inclination lifting capabilities.
Referring to
A flexible strap 12 extends through the handle engagement portion 11A having oppositely disposed ends 12A and 12B secured centrally to a panel engagement lifting bracket 13 of the panel carrying device 10 as will be described in detail hereinafter.
The flexible strap 12 can be of any suitable material configuration that has significant strength to accommodate a wide variety of lifting applications.
The panel carrying device has a primary one piece panel engagement and lift bracket 13 formed of a general angle iron configuration main body member 14 with an elongated material receiving platform portion 15 extending at right angles from a corresponding upstanding portion 16 as best seen in
A pair of spaced oppositely disposed parallel impact release tabs 17 and 18 are formed inwardly from their respective ends of the upstanding portion 16 in opposing orientation to the material receiving platform portion 15.
The release tabs 17 and 18 are formed by cutting and bending respective end portions towards one another at right angles to form the pair of spaced parallel impact release tabs 17 and 18. A lifting strap aperture attachment tab 19 is formed in the upstanding portion 16 midway between the hereinbefore described impact release tabs 17 and 18. The attachment tab 19 is formed by a pair of parallel longitudinally spaced cuts at 20 in a longitudinal edge 21 of the upstanding portion 16 allowing for bending angular deflection thereof to define the tab 19 outwardly in opposed relation to the release tabs 17 and 18.
An opening at 22 is formed in the attachment tab 19 through which respective ends 12A and 12B of the flexible lift strap 12 extend and are secured, in this example, by tying as best seen in
Referring now to
Typically the user (not shown) would use their foot, for example, to engage the impact portion of the upstanding portion 16 for positioning the platform 15 under the panel P. A leading edge 15A of the platform portion 15 is tapered so as to assist in the insertion under the panel P in this application.
Once engaged, the hereinbefore described flexible strap 12 and the attached handle 11 allows for a secure and proper extended grip for lifting the angled shaped main body member 14 of the panel carrying device 10 and the panel positioned thereon.
Once the panel P is positioned at its destination it can be easily released from the receiving platform 15 by tapping either one or both of the hereinbefore described impact and release tabs 17 and 18 sequentially dislodging the carrying device 10 of the invention out from under the panel P as described.
The preferred embodiment of the panel carrier 10 is constructed preferably of an integral piece of metal such as steel or aluminum for durability and strength given its use requirements and ease of angle and tab formation.
It will be evident, therefore, that given the universal nature of the receiving platform portion 15, it will be easily adapted to other engaging and lifting venues having engagement surface edges such as appliances, not shown, providing a safe, simple, portable and self-contained material engagement and lifting aid with an adjustable handle configuration to afford an effective grip and maneuvering of large material such as panels and the like.
Referring now to
A pair of longitudinally spaced apertured lift attachment tabs 34 are formed by cutting and outwardly bending respective end portions of the upstanding bracket portion 33. The alternate lift tabs 34 are foreshortened and apertured for receiving the free ends of a corresponding flexible strap and handle assembly representation 36 illustrated by broken lines in
An alternate tap and release tab 37 is formed centrally in the upstanding bracket portion 33 between and is bent outwardly similar to the lift tabs 34, but in opposition relation thereto. The tap and release tab 37 is defined by cutting and bending, as in the hereinbefore described lift tabs 34.
It will be evident that tap release tab 37 performs the function as the hereinbefore described multiple release tabs 17 and 18 in the primary form of the invention allowing the user, not shown, to physically tap or impact there against to unseat the receiving platform 32 from engagement under the lifting material after lifting, positioning and transporting has occurred.
The advantages of the alternate material carrier of the invention as described are that of the lift tabs 34 being spaced in relation to one another on the lifting bracket body member 31 by providing two independent spaced stabilizing attachment points for the flexible strap ends and handle assembly 36.
Such an orientation may be of increased value when engaging a variety of material to lift, but not limited only to sheet material, but other bulky items, as hereinbefore noted.
It will thus be seen that a unique and novel panel carrying device has been illustrated and described and it will be evident to those skilled in the art that various changes and modifications may be made thereto without departing from the spirit of the invention.
