In Germany September 15, 1937 The present invention relates to a snap connection for disconnectably connecting relatively thinmaterlals or -disconnectab ly connecting a relatively thin material too. base material.

I A Qbjectoi" the' present invention resides in the,provisionof a snap connection oi the type specified in. which themateriaito be fastened to another materialljs provided with openings which are, slipped' over a button member which member l", comprises .provisionsfiwhichi automatically prevent' disconnectioni'ofjhe" materials.

material.

Referring more particularly to the drawing, i 40 represents a base material, ,for examplethe can: vas of a tent to'which' a fastening element 2 is rigidly connected. Element 2 has a contracted part '3 and divergesupwardly therefrom to a part 4 of larger cross section so that an inverted cone 45 is. formed. The upper part 4 'of said cone part constitutes a guide for the cap part 5 which may have cylindrical configuration and is' pushed over the fastening member 2. A spring member 8 which is situated preferably inside 'the cap 5 50 tends to remove said cap from the fastening member 2 and base material I. Cap member 5 is provided with a plurality of openings"! into which openings part of individual locking members 8 extends; said locking members are prefer- 55 ably ball shaped and located inside can] and adjacent to the recess or neck 3 of fastening member 2.

The balls 8 which abut against the cone part of member 2 and. part of which balls individually fits into the openings i prevent complete removal of cap 8 by the action of spring member 8, Le, the balls 8 look pushbutton member 8 in the position illustrated in Figure 1 and vice versa.

9 is the matenal which is to befastened to the material I. Material 9 is provided with aihole l which is bordered or reinforced by means oi member I I which is 'g-shaped in case of a lindrical configuration f member 8. If member ill with the material 9 attached thereto is pushed overthe cap in the direction of arrows Ii, balls 8 and cap I are moved downward against thefaction of spring 6, and balls 8 move inward thereby making way for member ID. As soon as member Iii has passed the narrowest or neclo part 8 of member 2, cap 5 snaps upward due to the action 9 0! spring 6 and takes balls 8 with it. The latter move upward and outward because of the'diverging configuration of part 2 above the neck]; the de ice is then in the locking conditionillustrated in gure 1 whereby balls 8 prevent removal of member 10. Flg.2 shows the snap connection according to the present invention at the moment when member ill passes the neck 8 and balls 8 are in'innermost position. I

In order to be able to remove material 9 and member l0, cap I'must be'pressed downward from the position shown in Figure 1 to that shown in Figure 2. Material 8 and member I0 I may then he slipped upward and removed from he fastening device and thereby from material or base I. I

r The device shown in the drawing and described above is one possible embodiment of the present invention. It is, however, to be understood that it is not desired tobe limited to the exact details 40 or design and construction shown and described. for obvious modifications will occur to a person skilled in the art.

Whatis claimed is? l. A snap fastener comprising a stationary inner member, an outer member closely ntting over said inner member and being movable relative to said outer member, a resilient means disposed i between said members and tending to hold said my members in a predetermined position with respect to-one another, one of said members having an inclinedlportion, locking means disposed adjacent to said inclined portion and between said members and projecting from said outer member u ner member, an outer member movably and der the influence 0! said spring member and in-' clined portion.

2. A snap fastener comprising a stationary inner member, an outer member movably and closely fitting over said inner member and having an opening, a resilient means disposed inbetween said members and tending to hold said members in a predetermined position with respect to one another, one of said members having an inclined portion, a locking means disposed adjacent to said inclined portion and between said members and projecting from said outer member through said opening under the influence of said spring member and inclined portion.

3. A snap fastener comprising a stationary inclosely fitting over said innermember and having a plurality of openings, a resilient means disposed in between said members and tending to hold said members in a predetermined position with respect to one another, one 01 said members having a cone shaped portion, a plurality of locking means disposed adjacent to said cone shaped portion and between said members and individually projecting from said outer member through said openings under the influence of said spring member and inclined portion.

4. A snap fastener comprising a stationary. rotund center member having a neck portion and a diverging portion above said neck portion, a substantially cylindrical hollow cap. member closely and axially slidably' fitted oversaid cen-- ter member, a plurality of openings in theside of said cap member, a resilient means in-between said membersand tending to remove said cap member from said center member, a plurality of rotund locking members disposed in-between said
