STRUCTURE, USE AND MANUFACTURE OP FASTENERS BACKGROUND OF THE INVENTION
This invention relates to attachment devices and more particularly to their structure, manufacture and use.
A widely known type of device that is particularly useful in attaching tags to garments is in accordance with U.S. Patent 3,444.597. Each device is in the form of an elongated element or connector which joins a head member to a cross bar. The cross bar is typically applied from the bore of a slotted hollow needle, with the con¬ nector extending outwardly from the needle along the slot. When the needle is inserted into an object for which an attachment is desired, for example a price tag to a garment, the price tag is first positioned between the needle and the garment, following which the cross bar is propelled through the needle to the opposite side of the garment. In the propulsion process, the connector is folded against the cross bar. Once the cross bar is expelled from the needle it tends to reassume its original, relatively perpendicular orientation relative to the con¬ nector.
In the case of a typical attachment there is a smooth radius and transition between the cross bar and the connector. This transition often interferes with the desired restoration of the cross bar to its perpendicular position relative to the connector once the cross bar has been propelled through the garment and expelled from the needle.
Accordingly, it is an object of the invention to facilitate the use and manufacture of attachment devices. A related object is to facilitate the use and manufacture of attachment devices which are individually formed by connectors that join enlarged head portions to cross bars, the latter being perpendicularly disposed In relation to their associated connectors.
Another object of the invention is to promote the restoration of cross bars to their original equilibrium position after being expelled from the bores of slotted hollow needles. Another object of the invention is to facilitate the rapid, low cost attachment of tags to objects such as garments. A related object is to increase the number of fasteners per unit length of assemblages of fasteners used in fastener dispensing devices. A related object is to achieve increased packaging of fasteners without detriment to the ability of individual fasteners to regain their original equilibrium positions after being expelled from a fastener dispensing device.
SUMMARY OF THE INVENTION
In accomplishing the foregoing and related objects, the invention provides attachments in which each has a connector that forms a different transition with a cross bar. In one orientation, the connector forms a gradual transition with the cross bar, while in another orienta¬ tion, the transition is relatively abrupt. The use of an abrupt transition, coupled with a gradual transition, provides a toggle effect which promotes the reorientation of the cross bar after it has been folded against the connector and driven into an object.
In accordance with one aspect of the invention, the connector is tangential to the cross bar between planes that are perpendicular to the cross bar at its junction with the connector. The connector is desirably tangential to the cross bar at its cross sectional bisector. The cross bar desirably is connected to a neck which is coaxial with the connector.
In accordance with still another aspect of the in¬ vention, the abrupt transition between the connector and the cross bar is angular, and forms substantially a right angle.
In accordance with yet another aspect of the invention, the cross bar is joined to a neck by an inter¬ mediate region which has a smaller diameter than the neck, and neck advantageously has a tapered transition to the intermediate region.

DETAILED DESCRIPTION
With reference to the drawings, Figure 1 shows an assemblage 100 of individual attachments 10 being used in the tagging of an illustrative item 20 of merchandise using an attacher gun 30.
As indicated in Figure 1, the merchandise 20 il¬ lustratively a piece of cloth, is being tagged with a ticket 40 by one of the attachments 10-1 of the assemblage 100. For that purpose, the assemblage is inserted into a receiving channel of the gun 30 so that the individual connectors 11 of the attachments 10 extend outward through a slot 31. An illustrative gun 30 is of the kind shown in U.S. Patent 4,416,407 which issued November 22, 1983 to Arnold R. Bone. The gun 30 includes an internal plugger (not visible in Figure 1) that is used in driving a cross bar 12 of an individual fastener 10 through the bore of a slotted hollow needle 32 mounted at the frontal portion 33 of the gun 30. In the tagging operation, the tag or label 40 is inserted upon the needle 32 until its surface 41 engages the gun surface 33. The gun 30 and the tag 40 are then thrust through the merchandise 20 so that the needle 32 projects through the merchandise 20 to the other side. The trigger 35 of the gun 30 is then depressed to expel the cross bar 12-1 of the attach¬ ment 10-1 through the merchandise 20. This operation leaves the head portion 13-1 joined to the connector 11-1
so that when the needle 32 is withdrawn, the tag 40 is held to the merchandise 20 by the head portion 13-1 of the attachment 10-1.
In many attaching operations of the kind illustrated in Figure 1, the cross bar 12-1, which is folded against the connectors 11-1, as the cross bar 12-1 is driven through the merchandise, does return quickly to its equil¬ ibrium position with the cross bar 12-1 perpendicular to the connector 11-1. In some cases, the recovery of the equilibrium position is so slow that the attachment 10-1 can be withdrawn deliberately or accidentally from the merchandise, and thus defeat the tagging operation.
The invention overcomes the delays often encountered in restoration of the desired equilibrium position of the cross bar, after passage through the merchandise, by the introduction of a toggle structure at the junction of the connector with its associated cross bar. The toggle structure is specifically illustrated in Figures 3A - 3C. In addition, as indicated in Figure 2, the individual fasteners or attachments 10 are closely spaced upon a runner 14, without hindrance to the desired toggle effect. In this way, a large number of individual attachments 10 can be positioned upon a relatively short runner 14 and thus permit an increase in the number of attachments used with each assemblage having a prescribed length runner 14.
As indicated in Figure 3A, the illustrative connector 11-1 is joined to its associated cross bar 12-1 by a relatively abrupt transition T-j_ at an angle of about 90 degrees between the cross bar 12-1 and the connector 11-1. The actual junction of the connector and the cross bar can also be at a 90 degree angle, or can be a fillet with a slight reduction.
By contrast as shown in Figure 3B, the same connector 11-1 forms a relatively gradual transition at an angle greater than 90 degrees relative to the cross bar 12-1. The second transition T2 is more gradual than the other transition T^ and can be associated with a much larger radius of curvature.
The plane view of the transition of Figure 3B is set forth in Figure 3C.
As a result of the differences in the degree of transition Tj and g. the cross bar 12-1 produces an automatic toggle effect after being released from its condition of being folded against the connector 11-1, upon emergence from the bore of a slotted hollow needle used in driving the attachment through an object in the manner depicted in Figure 1.
8
Representative of parameters associated with the assemblage 100 and the individual fasteners 10 are the following:
The cross bars 12-1 have a diameter of about 30 mils and a length from end to end of about 300 mils. The runner has an illustrative diameter of 60 mils and is joined to the cross bar by a neck 15-1 with a diameter of about 25 mils extending to a taper 15-2 of about 30 degrees and a transitional neck 15-3 to the cross bar 12-1. The transition T-j_ has an illustrative 2 mil radius while the transition 2 is blended from the con¬ nector 11-1 to the cross bar 12-1.
The individual attachments 10-1 are spaced from one another by a pitch of about 45 mils and each attachment has a diameter as molded on the order of 30 mils. Each fastener as molded has a length on the order of 1.4 Inches.-
Following molding, the attachments 10 are stretched to extend the length as molded to approximately triple. There is a corresponding reduction in the connector diameter at the cross bar from about 28 mils to about 15 mils.
Other aspects of the invention will be apparent to those of ordinary skill in the art.
