Title:
ADJUSTABLE ATTACHMENT
United States Patent 3604068


Abstract:
A wrist attachment comprising an oblong and a tubular button having a plurality of aligned apertures two between two others extending in the direction of the length of the buttons and two apertures are sized to the string in use and the two other apertures are sized a few fractions larger than the string plus a lock-catch opening on the lower button to create a safety feature.

Primary Examiner:
Griffin, Donald A.
Claims:
Having described my invention what I claim as new and desire to secure by Letters Patent is

1. An adjustable-type fastener comprised of a part of elongated buttons one an elongated plate the other a tube, each button having a pair of large holes and a pair of small holes, the small holes of one button being aligned with the larger holes of the other button so that string threaded through the holes can be easily adjusted to fit securely about an attachment.

2. A fastener as described in claim 1 wherein the two outside holes in the tubular button are provided with slits for locking the string to prevent shifting in size of the adjustable fastener.

Description:
The general object of the invention is to provide an adjustable-type fastener for attaching one object to another by means of twine or rope which is easily adjustable to fit various sized objects and which can be easily attached or removed. A wrist attachment comprising an oblong and a tubular button having a plurality of aligned apertures two between two others extending in the direction of the length of the buttons and two apertures are sized to the string in use and the two other apertures are sized a few fractions larger than the string plus a lock-catch opening on the lower button to create a safety feature. It also embodies the feature of adjusting to fit securely without tightening about the object. This last feature is very advantageous for attaching an object to the wrist or ankle of a baby or handicapped person for keeping it from being dropped or thrown; also for attaching the weight rope to the ankle or leg undergoing treatment by traction.

The invention consists of the novel construction and combination of parts herein aftermore fully described and claimed. In the accompanying drawing I have shown the preferred form of my invention and be it understood that the invention is not limited to the forms described or people using it.

To simplify my drawing I refer to the parts of fastener as buttons, the object to which it can be attached, the holder and the attached object is referred to as the attachment. My useful device is based on the construction of two four-holed designed buttons threaded together and with a pulley-type method of operation.

FIG. 1 is top button

FIG. 2 is direct rear view of lower tubular button with lock-catch opening

FIG. 3 is method of threading

Referring to the figures by numerals of reference FIG. 1 and FIG. 2 are buttons having a series of apertures preferably four in enlinement. The apertures are sized to the string in use and a few fractions larger than the string. FIG. 1 is oblong in shape to coincide to the shape of the wrist. FIG. 2 is made from a tube. The apertures are punched through both walls of the tubular button therefore, it is designed the same as FIG. 1 on the front wall; but with an addition shown on the rear view wall there is an extra feature shown as a lock-catch opening on the two outer apertures. This lock-catch opening is sized narrower than the string in use. When the attachment is fastened to the holder the outer strings are pulled into the lock-catch opening which in turns grips the string firmly and prevents the shifting of the lower button out of the set position, developing a safety factor as for instance when an infants wrist becomes the holder it will not cut off circulation. Using the tube as a design for the lower button is also a safety feature in itself because the double wall construction hinders shifting of the lower button and makes it unnecessary to provide the lock-catch openings shown in FIG. 2 when the attachment is to fastened to an object such as a chair or display board where it is desirable to have a ready means of changing items. The lock-catch is often advantageous to prevent pilfering of display items.

FIG. 3 is the string and method of threading used. By using this method to develop the pulley-type of operation this solves the problem of fitting different sized wrists. Therefor, the length of the string is determined by the one using the attachment. Also the working order is geared to simplicity. On and off instantly.

Having the larger apertures of the top and lower buttons lying and threaded in reversed position to the smaller apertures developes space allowing freedom of movement of the pulley operation.

Having the two smaller apertures of the top and lower buttons lying and threaded in reversed position to the larger makes these smaller apertures hug the string to form a safety barrier on the lower button when placed up to the wrist. Therefore, the reversed positions of the buttons create space between the lower button and the wrist to hinder tightening of the lower button when strings are pulled.

For the structure of the buttons the preferred materials to be used are wood, plastic, or aluminum because of their lightweight, durable and nontoxic nature.

The following serves to illustrate the use of the fastener: to place on to wrist the wrist is slipped through between the outer string bypassing the two center strings and out again. Then lower button is pulled up to the wrist. To remove from the wrist lower button is pulled down and buttons are pulled apart.
