Patent Application
20200102679
Save the modern sewing machine, seamstresses today often struggle by with equipment that would be recognizable by their great grandmothers. Vintage brass, silver and porcelain thimbles including some said to date to the 19th Century are offered for sale on-line, with precious little separating functionality of these “vintage” thimbles from modern thimbles typically formed from stainless steel or hard polymers. Yet there is much to be desired to improve the functionality as the typical thimble is formed from hard rigid material which makes thimble bearing digits usable primarily for pushing a needle into material but greatly impairing use of that digit for gripping, as the lateral surfaces of thimbles formed from hard material typically exhibit a rather low coefficient of friction. This application relates to a low cost thimble gripper combination which enables the user to both push a needle into material and then, on the other side of the material, grasp the needle between the thumb and forefinger and pull it through without removing the thimble from the forefinger.
Braley, U.S. Pat. No. 4,102,479 discloses a thimble having a resilient frusto-conical resilient liner cooperating with a concentrically disposed resilient pad defining a circumferentially extending space adapted for use by a person having long fingernails, with the end of the finger in abutting contact with the resilient pad. The liner is formed from a soft coarse resilient material, allowing air to the enclosed finger portion while keeping the enclosed finger portion cool and dry. Optionally, the longitudinal length of the thimble may be increased by a resilient band removably gripping the bead on the end portion of the thimble opposite the end portion that is closed by the end piece.
Adams, U.S. Pat. No. 4,127,222, discloses a sewing thimble having an elongated, tubular body consisting of a pliable material, such as rubber, wherein a plurality of vent holes are disposed about the annular body portion, the inner bore thereof being designed to conform to the average finger, including those having extended fingernails. The forward head portion of the thimble is enlarged with a thickened area of a hard rubber or plastic to allow for forceful engagement with a needle to be threaded. Alternative arrangements include a protective shield embedded within the head portion and a threading-and-cutting device mounted to the thimble at the tip of the enlarged head thereof.
Joy, U.S. Pat. No. 4,239,134, discloses a flexible thimble for sewing which allows the thimble to conform to the finger for fit and comfort; providing a supple surface to allow the user to actually feel the needle; and provides a protective means located near the closed end of the thimble for covering part of the normal fingertip and fingerprint area, to protect the finger from the penetration of sharp objects.
Hostetler, U.S. Pat. No. 4,643,341, discloses a sewing thimble having an inner barrel, a blade segment and an outer shell. The molded inner shell is semi-rigid and has a projecting lug for positioning the cutting edge of the blade segment. The outer shell is resilient or slightly deformable and is molded around and encases the inner barrel. The outer shell has a laterally projecting and thickened bulb area which covers the inner barrel lug beneath the cutting edge of the blade segment. A flap cut is formed in the bulb area so that a user may grip and pull a needle and thread by thumb pressure applied against the bulb area.
Callian, U.S. Pat. No. 5,765,731, discloses a thimble for use in quilting. sewing or the like to manipulate a needle including a flexible member and a shield member. The flexible member has four notches in spaced apart relation forming four tab portions positioned therebetween. The notches enable the tab portions to be bent about a finger of a person for conforming and fitting the thimble to the finger. One of the tab portions may be elongated to provide an elongated flap for fitting the thimble on a finger with a long fingernail. The flexible member is attached to or integrally formed with an adhesive material for securing the thimble to the finger of a person to prevent slippage of the thimble. The thimble further includes a shield member attached to the adhesive material of the flexible member for protecting the finger from contact with the needle. The shield member includes a dimple for seating the needle during use of the thimble and a curved surface for conforming to the finger of a person.
Boone et al., U.S. Pat. No. 5,803,322 discloses a stitch laying tool having a cylindrical thimble body having a center axis and a cylindrical side wall with opposite open ends to receive the tip of a stitcher's finger. An elongated stiff wire is secured to the side wall and extends substantially parallel to the center axis and has an outer end extending beyond one end of the cylindrical side wall. The outer end of the stiff wire has a short straight wire segment which forms an angle with respect to the stiff wire.
Miller, U.S. Pat. No. 6,726,068 B2, discloses a finger protective device constructed from elastomeric materials having a working surface covering the fleshy portion of a finger having sufficient strength and hardness to avoid penetration by a needle, yet being elastomeric to accommodate large variations in shape. The working surface may be interrupted by ribs or protrusions to prevent needle slippage. A compliant member surrounds the remainder of the finger and is softer in order to comply with the majority of finger shape variations. The thimble thus formed is designed to conform to the shape of a finger and remain adhered by frictional means to provide comfortable protection.
Jerome, U.S. Pat. No. 7,296,715 B1, discloses a thimble device for protecting fingers and thumb from a needle during a sewing operation wherein the thimble device comprises a top needle bearing surface having a dimple formed therein and two side surfaces with each side surface having an angled portion and a curved portion. The curved portions are sized and shaped for receiving a portion of the fingers when the thimble device is seated between the fingers. The thimble device further includes an angled front surface, an angled rear surface, and a curved bottom surface sized and shaped for receiving a portion of the thumb.
A flexible thimble gripper comprises a flexible elastomeric strip terminating in an elastomeric dome formed thereupon at one end thereof, projecting from said strip in one direction, said dome having a friction enhancing surface formed on an outer surface thereof, said strip having an elastomeric thimble formed at the opposite end thereof, said thimble projecting therefrom in said one direction and having a rigid polymeric cap joined thereto, said cap terminating in a region having a slip resistant surface formed therein, said cap being cutaway on a surface contiguous with the surface of said dome upon which said friction enhancing surface is formed, a friction enhancing surface being formed on said elastomeric band in the region adjacent said cutaway, said dome and said thimble being adapted to be mounted upon the thumb and a finger of a user's hand so that a needle may be pushed into material by pressure from the slip resistant surface and drawn from said material when gripped between the friction enhancing surface of said dome and the friction enhancing surface formed on said elastomeric band in the region adjacent said cutaway in said cap. Preferably, the thimble gripper of the present invention is formed by dual shot injection molding.
