Abstract
A fastener in the form of a release fastener, snap fastener and the like for pockets, cases and the like, also comprising a female part formed with an insert opening. A closing head operatively releaseably lockingly engages in the insert opening, and a male holding part carries the closing head. The closing head is formed with a rearward collar supported on the male holding part, with the closing head extending through a hole in the male holding part, and including a plug-in snap-catch connection between the male holding part and the closing head.
Claims15
A fastener in the form of a release fastener, snap fastener and the like for pockets, cases and the like, comprising
- two identically formed female type members,
- one of said members serving as a female part and formed with an insert opening,
- a closing head operatively releaseably lockingly engaging in said insert opening,
- the other of said female type members constituting a male holding part formed with a hole carrying said closing head, said closing head extending through said hole and being formed with a rearward collar supported on said male holding part,
- means on each of said two female type members, respectively defining said hole of said male holding part and defining said insert opening of said female part, for a plug-in snap-catch connection between said male holding part and said closing head and for a plug-in snap-catch connection between said female part and said closing head, respectively,
- said closing head comprises a closing head pin formed with two catch grooves disposed one behind the other in a longitudinal direction of said pin, said pin including a center zone of enlarged cross-section separating said two catch grooves from each other,
- one of said catch grooves lies adjacent said collar and cooperates in a snap-catch connection relationship with an edge range of said hole of said male holding part cooperatively constituting said plug-in snap-catch connection means of said male holding part,
- the other of said catch grooves is formed adjacent a free end of said pin and cooperates in a locking position of the fastener in a releasable snap-catch locking engagement relationship with an edge range of said insert opening of said female part cooperatively constituting said plug-in snap-catch connection means of said female part,
- said male holding part and said female part are identically formed and each have a front surface facing each other and an outer peripheral edge, the latter aligned in a common plane with said center zone in the locking position of the fastener, respectively,
- said front surface of said male holding part and said front surface of said female part are funnel shaped and cooperatively form a trough which widens toward a center point thereof in the locking position of the fastener, and
- said front surface of said male holding part and said front surface of said female part are clamped abuttingly against each other adjacent said outer edges respectively in the releasable locking position of the fastener by said catch grooves of said closing head engaging with said plug-in snap-catch connecting means of said male holding part and said female part, respectively.

A fastener in the form of a release fastener, snap fastener and the like, for objects, comprising
- two identically formed female type members each formed with an opening therein, said members each having an outer edge,
- a closing head including a shank pin formed with two annular catch engagement grooves spaced apart from each other, one of said grooves engaging in catch locking engagement relationship with said opening of one of said members, the other of said grooves engaging in catch locking engagement relationship with said opening of the other of said members, said closing head having an enlarged collar at one end, said collar being larger than said openings, thereby preventing removal of said closing head from said members in one direction,
- attaching means on said outer edges, respectively, of each of said members, respectively, being directed away from each other in opposite directions for permanently fastening said members, respectively, to the objects.
A fastener in the form of a release fastener, snap fastener and the like for pockets, cases and the like, comprising
- two identically formed female type members,
- one of said members serving as a female part and formed with an insert opening,
- a closing head operatively releaseably lockingly engaging in said insert opening,
- the other of said female type members constituting a male holding part formed with a hole carrying said closing head, said closing head extending through said hole and being formed with a rearward collar supported on said male holding part,
- means on each of said two female type members, respectively defining said hole of said male holding part and defining said insert opening of said female part, for a plug-in snap-catch connection between said male holding part and said closing head, and for a plug-in snap-catch connection between said female part and said closing head, respectively,
- two securing counter retainer members adapted to abut one side of a corresponding material, respectively, and
- each of said female type members have a peripheral edge portion bent in opposite directions relative to each other toward one of said retainer members, respectively, defining a pot shape having therein a pot space, as well as fastening claws extending from said edge portion and securely engaging said retainer member, respectively.
