Abstract

An ergonomic apparatus for handling a hinged lid that reduces force required to open the hinged lid and bending by a user, maintains the lid in an open position to prevent accidental closure of the lid, and assists with closing the lid. The apparatus has a horizontal member with an attachment means for removably coupling the apparatus to the hinged lid, a vertical member extending from a proximal end of the horizontal member, and a handle in operable communication with the vertical member. The vertical member and handle are configured relative to the horizontal member such that when the vertical member is positioned on a flat surface, the handle is raised above the flat surface by about 10° to 25° and the hinged lid is maintained in an open position having an angle greater than 90° relative to an opening the hinged lid was covering.

First claim

The invention claimed is:

1. An apparatus for handling a hinged lid comprising:
a horizontal member having an attachment means for removably coupling the apparatus to the hinged lid;
a vertical member extending from a proximal end of the horizontal member in a generally vertical direction forward of an axis orthogonal to the horizontal member that forms a first acute angle between the vertical member and the horizontal member;
a handle in operable communication with a distal end of the vertical member and positioned to extend from the distal end of the vertical member and form an obtuse angle relative to the vertical member such that when the vertical member is positioned on a flat surface, the handle forms a second acute angle between the handle and the flat surface; and at least one side support having a triangular shape with interior angles corresponding to the first cute angle, the at least one side support affixed to a side of the vertical member and a side of the horizontal member to rigidly fix the first acute angle in a working position.

2. The apparatus of claim 1 , wherein the the first acute angle between the vertical member and the horizontal member is about 79° to 81°.

3. The apparatus of claim 1 , wherein the obtuse angle of the handle is about 155° to 170°, such that when the vertical member is positioned on the flat surface, the second acute angle between the handle and the flat surface is in a range of about 10° to 25°.

4. The apparatus of claim 1 , wherein the attachment means is positioned between a center and a distal end of the horizontal member.

5. The apparatus of claim 1 , further comprising an anti-slip extension in operable communication with the distal end of the horizontal member, the anti-slip extension having a length that extends away from the distal end of the horizontal member and beyond a non-hinged end of the hinged lid.

6. The apparatus of claim 1 , further comprising a first stiffener affixed to and extending at least a portion of the length of an internal surface of the vertical member.

7. The apparatus of claim 6 , further comprising a second stiffener affixed to and extending at least a portion of the length of an internal surface of the horizontal member.

8. A method for making an apparatus for handling a hinged lid comprising:
providing a horizontal member with an attachment means for removably coupling the apparatus to the hinged lid;
extending a vertical member from a proximal end of the horizontal member in a generally vertical direction forward of an axis orthogonal to the horizontal member to form a first acute angle between the vertical member and the horizontal member;
positioning a handle in operable communication with and to extend from a distal end of the vertical member to form an obtuse angle relative to the vertical member such that when the vertical member is positioned on a flat surface, the handle forms a second acute angle between the handle and the flat surface; and affixing at least one side support having a triangular shape with interior angles corresponding to the first acute angle to a side of the vertical member and a side of the horizontal member to rigidly fix the first acute angle in a working position.

9. The method of claim 8 , wherein the first acute angle between the vertical member and the horizontal member is about 79° to 81°.

10. The method of claim 9 , wherein the the obtuse angle of the handle is about 155° to 170°, such that when the vertical member is positioned on the flat surface, the second acute angle between the handle and the flat surface is in the range of about 10° to 25°.

11. The method of claim 8 , further comprising positioning the attachment means between a center and a distal end of the horizontal member.

12. The method of claim 8 , further comprising affixing an anti-slip extension in operable communication with the distal end of the horizontal member, such that the anti-slip extension extends away from the distal end of the horizontal member and beyond a non-hinged end of the hinged lid.

13. The method of claim 8 , further comprising affixing a first stiffener to an internal surface of the vertical member to extend at least a portion of the length of the vertical member.

14. The method of claim 13 , further comprising affixing a second stiffener to an internal surface of the horizontal member to extend at least a portion of the length of the horizontal member.

15. A method for handling a hinged lid comprising:
removably coupling an attachment means of a horizontal member of a hinged lid handling apparatus to a non-hinged end of the hinged lid, such that a connection point between the horizontal member and a vertical member extending from a proximal end of the horizontal member in a generally vertical direction forward of an axis orthogonal to the horizontal member at a first acute angle relative to an upper surface of the horizontal member where at least one side support having a triangular shape with interior angles corresponding to the first acute angle is affixed to a side of the vertical member and a side of the horizontal member to rigidly fix the first acute angle in a working position, the horizontal member is positioned proximate to a hinged end of the hinged lid;
pulling a handle in operable communication with a distal end of the vertical member to lift the non-hinged end of the hinged lid;
positioning the vertical member on a flat surface, such that the hinged lid is maintained in an open position having an angle greater than 90° relative to an opening the hinged lid was covering and the handle forms an acute angle between the handle and the flat surface in a range of about 10° to 25°.

16. The method of claim 15 , wherein the removably coupling step further comprises extending an anti-slip extension in operable communication with the distal end of the horizontal member and beyond the non-hinged end of the hinged lid.
