Umbrella having a flat cross-sectional shape in closed condition thereof

Claim 2

Umbrella having a relatively flat cross-sectional shape in closed condition thereof includes an umbrella stick, a relatively flat crown member mounted at one end of said stick, roofsupporting ribs articulatingly connected to said crown member, a relatively flat cap member carried by said crown member, and umbrella roof covering having a portion thereof disposed between said crown and said cap members, and means clamping said members together with said roof-covering portion therebetween and comprising first structures provided on said members and cooperatively form locking said members against rotation with respect to the axis of said stick and second structures formed on said members and cooperatively force locking said members against displacement in the direction of the axis of said stick, the second structure on at least one yieldable said members being resilient so as to be yieldable relative to the second structure on the other of said members in response to a force of given minimum strength applied thereto for separating said members from one another in intact condition.

Claim 3

Umbrella according to claim 1 wherein said members are clampable in only one rotary position wherein they are disposed parallel to one another.

Claim 4

Umbrella according to claim 1 wherein said members are clampable in only two positions rotatably offset from one another through an angle of substantially 180* and wherein they are disposed parallel to one another 4 Umbrella having a relatively flat cross-sectional shape in closed condition thereof includes an umbrella stick, a relatively flat crown member mounted at one end of said stick, roof-supporting ribs articulatingly connected to said crown member, a relatively flat cap member carried by said crown member, an umbrella roof covering having a portion thereof disposed between said crown and said cap members, and means clamping said members together with said roof-covering portion therebetween and comprising first structures provided on said members and cooperatively form locking said members against rotation with respect to the axis of said stick and second structures provided on said members and cooperatively force locking said members against displacement in the direction of the axis of said stick, said clamping means comprising a bead formed on one of said members, and a corresponding groove formed in the other of said members for clampingly receiving said bead therein.

Claim 5

Umbrella according to claim 4 wherein said cap member is formed of resilient synthetic material whereby said bead yieldably snaps into and out of said groove.

Claim 6

Umbrella according to claim 4 wherein said clamping means includes a yieldable cushion disposed between said members, at least one of said members having projections embeddable in said cushion for frictionally locking said members together with said cushion and roof covering therebetween.

Claim 7

Umbrella according to claim 4 wherein said bead and said groove are noncircular in shape.

Claim 8

Umbrella having a relatively flat cross-sectional shape in closed condition thereof includes an umbrella stick, a relatively flat crown member mounted at one end of said stick, roof-supporting ribs articulatingly connected to said crown member, a relatively flat cap member carried by said crown member, an umbrella roof covering having a portion thereof disposed between said crown and said cap members, and means clamping said members together with said roof-covering portion therebetween and comprising first structures provided on said members and cooperatively form locking said members against rotation with respect to the axis of said stick and second structures provided on said members and cooperatively force locking said members against displacement in the direction of the axis of said stick, said clamping means comprising at least one projection Extending from one of said members, eccentrically to said stick, and at least one corresponding recess formed in the other of said members and registrable with said projection for receiving said projection therein.

Claim 9

Umbrella having a relatively flat cross-sectional shape in closed condition thereof includes an umbrella stick, a relatively flat crown member mounted at one end of said stick, roof-supporting ribs articulatingly connected to said crown member, a relatively flat cap member carried by said crown member, an umbrella roof covering having a portion thereof disposed between said crown and said cap members, and means clamping said members together with said roof-covering portion therebetween and comprising first structures provided on said members and cooperatively form locking said members against rotation with respect to the axis of said stick and second structures provided on said members and cooperatively force locking said members against displacement in the direction of the axis of said stick, said clamping means comprising at least one projection Extending from one of said members, eccentrically to said stick, and at least one corresponding recess formed in the other of said members and registrable with said projection for receiving said projection therein.

Claim 10

Umbrella according to claim 8 wherein said projection is formed with a radially yieldable collar, and said recess has an enlarged-diameter portion forming a shoulder and adapted to receive said collar therein in abutting engagement with said shoulder.

Claim 11

Umbrella according to claim 8, wherein said one member from which said projection extends is formed with a hollow space for receiving therein a marginal portion of said umbrella roof covering.

Claim 12

Umbrella according to claim 1 wherein said crown member is elongated and is provided with means at the respective longitudinal ends thereof for hingedly connecting said roof-supporting ribs to said crown member.

Claim 13

Umbrella according to claim 11 wherein said clamping means comprises a pair of projections extending from one of said members, eccentrically to said stick, the other of said members being formed with a pair of recesses registrable with said projections, respectively, for receiving said projections therein.

Claim 14

Umbrella according to claim 12 wherein said registrable projections and recesses are located between aid stick and said means for hingedly connecting said roof-supporting ribs to said crown member.

Claim 15

Umbrella according to claim 11 wherein said crown member is formed with a peripheral groove and a plurality of mutually spaced notches extending across said peripheral groove at said longitudinal ends of said crown member said roof-supporting ribs having an end formed with an eye therein and received in said transverse notches, respectively, and at least one wire secured in said peripheral groove and extending through the eyes of said roof-supporting ribs so as to form a pivot for said roof-supporting ribs.

Claim 16

Umbrella according to claim 14 wherein the notches at each longitudinal end of said crown member are disposed at an inclination to one another.
