Abstract

An end attachment for watch bands which permits use of a watch band with wrist watches having different spacings between their attachment lugs. The attachment includes a generally tubular insert member which includes at least one outwardly biased, inherently resilient tab, at least one side of the tab comprising a cam surface inclined towards the end of the tab for facilitating insertion of the insert member into and withdrawal of the insert member from a generally tubular end member of the end attachment which has a slot intermediate its ends.

Claims

1. An end attachment for a watch band adapted to be mounted between spaced lugs of a wrist watch case comprising a generally tubular end member having a slot intermediate its ends and a plate member extending towards the band, means for connecting the plate member to a watch band, and a generally tubular insert member disposed within said tubular end member, said insert member being longer than said tubular end member, said insert member comprising at least one outwardly biased, inherently resilient tab extending outwardly therefrom into said slot of the tubular end member, at least one of the sides of said tab comprising a cam surface which is inclined towards the end of the tab, whereby said insert member is detachably retained within said tubular end member by coaction between said tab and the sides of said slot, but it may be removed by moving the insert member axially in one direction, whereupon action of the cam surface of said tab against the adjacent side of said slot causes the end of the outwardly biased tab to be moved inwardly of tHe tubular insert member and out of the slot, freeing the insert member for further axial movement.

2. An end attachment according to claim 1, wherein a second cam surface is provided on the opposite side of said tab from said first cam surface.

3. An end attachment member according to claim 1, wherein said insert member comprises a longitudinal slot, a first outwardly biased, inherently resilient tab extending from one side of said slot towards its centerline, a second outwardly biased inherently resilient tab extending from the other side of said slot towards the first tab, at least one of the sides of each tab comprising a cam surface which is inclined towards the end of the tab, whereby said insert member is retained within said tubular end member by coaction between said tabs and the sides of the slot in the tubular end member, but it may be removed by moving the insert member axially in one direction, whereupon action of the cam surfaces of said tabs against the adjacent side of the slot in the tubular end member causes the ends of the outwardly biased tabs to be moved inwardly of the tubular insert member out of the slot, freeing the insert member for further axial movement.

4. An end attachment according to claim 3 wherein a second cam surface is provided on the opposite side of each of said tabs from the first cam surface.

5. An end attachment according to claim 1 wherein the tubular insert member is provided with a slot extending inwardly from one end for use in removing a spring pin of a watch and the tubular end member is provided with a wider slot extending inwardly from one end and at least partially registering with the aforesaid slot for use in removing the tubular insert member from the tubular end member.
