Handle attachment for a folder

Abstract

An attachment for a folder includes a handle and a boot attachable to a folder. The boot has a boot recess in which a handle body of the handle is received when the handle is in a retracted position, in which the boot surrounds the handle body. A support member of the handle is attached to the handle body and is movably associated with the boot below the boot surface. Thus, the handle body is retractably extendable from the retracted position to an extended position in which the handle body is spaced from the boot back for enabling grasping of the handle body by a user.

Description

BACKGROUND OF THE INVENTION

Folders are known which include a handle on one or more panels of thereof. For example, U.S. Pat. No. 4,098,443 teaches a book with an integral handle extending from a spine section of the book. The handle requires a special spine disposed on the inside of the book cover, to which the handle is directly connected, and from which page groups are mounted. Also, the handle protrudes from the outer surface of the book cover with angular edges and would thus catch when the if the book were slid against an object, such as a shelf. Also, the spine portion of the book cover remains exposed, and subject to wear and tear.

U.S. Pat. No. 1,269,859 teaches a music holder with two covers and a back. A handle is disposed on the back and lies thereagainst. The handle itself and attachments that secure the handle to the back protrude with angular edges from the cover of the book, also easily catching on objects adjacent to the handle.

A handle attachment for a folder is needed which is not prone to catching on shelves or other objects and which provides a graspable surface for increased ease of use.

SUMMARY OF THE INVENTION

The invention relates to an attachment for folders that has a handle and a boot that surrounds the handle. The handle is movable from a retracted position in which the body of the handle is received in a recess of the boot, to an extended position in which the handle body is spaced from the boot to enable carrying by a user. The boot prevents the handle from catching on objects adjacent thereto, such as a shelf when the folder is placed thereon. The boot also prevents wear and absorbs impact to portions of the folder that are otherwise susceptible to damage, such as seams and corners of the folder, extending the useful life of the folder. The boot and handle also preferably have a rounded rubber surface that provides a comfortably grippable portion for a user.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 1-4, attachment 10 is attached to an exterior of a folder 12, such as a notebook, folio, or planner. The attachment 10 includes a boot 14 that has an outer surface 16, which follows a smooth contour and runs the length of the folder 12. The boot 14 has a back with an at least semirigid skeleton 18 of sufficient stiffness to retain the shape of the outer surface 16 boot 14. The skeleton 18, preferably made from ABS plastic, also includes ribs 20 extending towards the folder 12 to support the skeleton and retain the shape thereof during impact against the attachment 10. The skeleton 18 also includes columns 21 with threaded bores to receive fasteners.

The back also has a resilient cover 22 which is less stiff than the skeleton 18, is disposed therearound, and defines the outer surface 16 to provide a grippable surface for a user of the folder 12. Even when used with a folder 12 that has only flat sides, the outer surface 16 of the attachment 10 provides a more comfortable surface which is easily grasped by the user than the outside surface of the folder 10. The cover 22 is preferably made from an elastomer such as rubber and is overmolded around the skeleton 18 to include sprues 24 which penetrate openings in the skeleton 18 and reattach to the outer portion of the cover 22, locking to the skeleton 18. The cover 20 has a lip 25 around the underside of the skeleton 18 to hold the cover 22 thereon.

A rigid plate 26 of the boot 14 underlies the back of the boot 14 and is disposed between the back and spine 28 of the folder 12. The plate 26 includes a guide member with rails 30, which include races 32 with elongated slots attachable perpendicular to the base of the plate 26. The plate is attachable to spine 36 of the folder 12. Each race 32 terminates with a stop 34 at one end. At the opposite end from the stop 34, each race 32 is open at a race opening 37. A control portion including a pin 38 extends laterally across each guide member 30. Notches 40 receive columns 21 of the skeleton 18 in interlocking relationship for preventing relative movement therebetween tangent to the folder spine 36.

A recess 44 with a handle opening 46 is defined through the cover 22 and skeleton 18, interrupting the outer boot surface 16. A handle positioner 48 is mounted to the plate 26, facing the handle opening 46, with protrusions 50 of the positioner 48 that are received in openings 51 of the plate 26. At least one of the protrusions 50 preferably has a widened end to prevent separation of the positioner from the plate 26. The lateral ends of the positioner 48 are sloped to allow handle support members, discussed below, to slide adjacent the positioner 48.

The attachment 10 also has a handle 52 with a handle body 54 attached to support members 56, which are preferably made from a single, substantially flat strip. The handle body 54 and the cover 22 comprise the same material that forms the outer boot surface 16. The handle body 54 is receivable through the handle opening 46. During assembly, the handle body 54 is passed through the handle opening 46. With the back of the boot 14, including the skeleton 18 and cover 22, placed against the plate 26, the handle body 52 is supported by the positioner 48. The positioner 48 is configured to position handle surface 58 to generally continue the smooth outer contour of the outer surface 16 of the boot 14 when the handle 52 is in a retracted position. In the preferred embodiment, the handle surface 58 is generally flush with the outer boot surface 16 when in the retracted position and is surrounded by the boot 14 and extends along the lateral sides of the handle body. FIGS. 2 and 5 show the boot surrounding substantially the entire handle body in a plane generally parallel to the recess 44. The positioner 48 also blocks the handle body from further retraction into the handle opening 46 beyond the retracted position. In the retracted position, the height 60 of the handle surface 58 above the base of the boot 14 is similar to the height of the outer surface 16 of the boot 14 above its base.

Each support member 56 has a guided portion, which preferably is a laterally extending pin 62 received in races 32 and in a cylindrical end member 63 of the support member 56. Controlled portion 64 of each support member 56 passes below the pin 38, controlling the path of the support member 56 when the handle 52 is retracted and extended. Thus, the handle 52 is movably associated with the races 32 below the outer boot surface 16.

As shown in FIG. 5 the handle body 54 has lateral sides having a length and separated by a width that is substantially smaller than the length. Also, the recess width 66 extending laterally thereacross is wider than the handle width 68 extending laterally thereacross. The recess 44 is configured to such that a grasping indentation 70 is defined on each side of the handle body 54 for receiving a user's fingertips for grasping of the handle body 54.

Referring to FIG. 6, when the handle 52 is grasped and lifted from the recess 44, the support members 56 pull the pins 62 along the races 32 towards the handle body 54 until pins 62 contact the stop 34, which prevents further extraction of the handle body 54 from the recess 44. The support members 56 move around pins 38 as the handle 52 is moved to the extracted position shown, spaced from the boot back for enabling grasping of the handle body 54 by a user.

The resiliency of the support member 56 and handle body 54 biases the handle body 54 towards the retracted position, rendering this the naturally assumed position of the handle 52 when released. Also, this resiliency permits insertion of the pins 62 in the race 32 during assembly by pulling the pins 62 away from the handle body 54, past their naturally assumed position, and upwardly into the race openings 37 by stretching the support members 56.

The folder 12 preferably includes rigid or semirigid panels, including folder covers 72 and the spine 36 pivotably attached together at seams or shoulders. A closure, such as a zipper and attached fabric strips 73, preferably releasibly attaches the folder covers 72. The boot 14 is attachable preferably to the spine 36, with the base of the boot 14 in abutment therewith. Fasteners 74 extend from the inside of the folder 12, through the spine 36, and into the columns 21 of the skeleton 18, retaining the plate 26 against the spine 36.

Width 76 of the boot 14 between lateral edges 78 thereof other is approximately the same as the width of the spine 36 to protect the entire spine 36 from wear and impact. Preferably, the boot 14 is substantially coextensive with the spine 36 edges and overlies the spine edges 36.

Referring to FIGS. 2 and 7, a binder assembly 80, preferably including binder rings 82 for holding papers, is fixed to the folder 12 with rivets 84, which extend through the folder 12 but not through the attachment 10. The fasteners 74 are disposed outside the perimeter of the binder assembly 80 and are independent therefrom. Also shown in FIG. 7 is the concave outer surface of the handle positioner 84, which corresponds to the shape of the handle body 54 to support the handle body 54 over a large area.

Referring to FIG. 8, the cover 22 has end flaps 86 extending generally perpendicular to the outer surface 16 of the boot back and extending adjacent edges 88 of the spine 36 to protect the edges 88. The flaps 86 have a notch 90 to facilitate outward movent of binder levers 92 during operation of the binder assembly 80.

One of ordinary skill in the art can envision numerous variations and modifications. All of these modifications are contemplated by the true spirit and scope of the following claims.
