Definitions

  • the invention relates to a folding umbrella.
  • Folding umbrellas are generally provided with a stick composed of a telescoping upper and lower member and with roof supporting ribs consisting of displaceable sections; these roof rib sections are extended, during the opening of the umbrella by main braces, which are operatively connected with the roof ribs.
  • the main braces are supported by auxiliary braces connected at their inner ends with the umbrella stick or with the roof ribs.
  • Fig. 1 is a schematic side view of a part of the umbrella in the closed position
  • Fig. 2 is the same side view of the umbrella in the shortened position
  • Fig. 3 is a vertical sectional view of the middle portion of a roof rod
  • Fig. 4 is a side view of a structural detail
  • Fig. 5 is a partial side view of another embodiment of the invention, the full lines indicating the first stage and the dotted lines the final stage of the opening of the umbrella, and
  • Fig. 6 is a side view of a constructional detail used in connection with the embodiment of the invention shown in Fig. 5.
  • the umbrella stick shown in Figs. 1 to 4 consists of the telescoping members 1 and 2.
  • the upper stick member 1 carries the crown 3.
  • the roof ribs consisting of collapsible and extensible upper and lower sections 8, 9 are pivotally connected with crown 3.
  • a spring catch 4 provided on the stick member 1 holds the umbrella in the opened position.
  • the upper end of the lower roof rib section 9 is by means of pivot 11, Fig. 3, connected with the upper end of brace 10; the lower end of the brace 10 is connected with main slide 5.
  • An auxiliary brace 13 is pivotally connected at 12 with brace 10; this auxiliary brace 13 is at its upper end pivoted to the auxiliary slide 14.
  • the roof rib sections 8, 9 are guided by sleeves 15, 16, the sleeve 15 being fastened to the lower end of roof rib section 8; the other sleeve 16 carries a pivot 11; roof rib section 8 has an inner cavity and sleeve 16 is displaceable on rib section 8, Figure 3.
  • a resilient member is provided in conformity with the invention, which curbs the displacement of the roof rib portions 8, 9.
  • This member may be constructed as a wire spring 17, 18, 19, Fig. 4, which is located between the ends of the roof rib portions 8, 9; it acts to resiliently retard the displacement of the roof ribs the end of the roof ribs 9 being slightly bent, see Fig. 3, to form the bent-off end 25.
  • the invention is based on a curbing or retardation of the premature displacement of the roof rib members 8, 9 and spring 17, 18, 19 may, therefore, be defined as a constantly operative means retarding the displacement of the roof ribs; for this purpose the spring may be given a certain amount of pre-tension. It is advisable to make the spring of steel wire or steel band. As shown in the drawing, the spring consists of a resilient two-shank steel wire. The one shank 19 of the spring is located in the inner cavity of roof rib section 8, Fig. 3;
  • the spring is held with its looped end 18 on shank 17 by a pivot 11, which is attached to the end of rib 9.
  • the end of the shank 19 of the spring, Fig. 4 is slightly inwardly bent and slides along rib 8 during the displacement of the latter.
  • Shank 19 therefore acts as a constantly reactive brake.
  • looped end 18 of the spring shank 17 is bent to form an aperture 20, Fig. 4; in this manner, the looped end 18 may be laterally pushed over pivot 11 or removed from the same.
  • the braces and the roof ribs in the closed position of the umbrella are parallelly positioned the play always present in the joints permits for a certain difference in the spread positions of the individual roof ribs. Therefore, the roof ribs located beneath the stick, which is generally held in a horizontal position during the opening thereof, may slightly spread from the stick due to their own weight, whereas for this reason the upper ribs will be close to the stick.
  • the spreading of the roof ribs is simplified by the creation of a certain spreading effect, in the closed position of the umbrella between the auxiliary braces or the roof ribs and the stick or the main braces.
  • the purpose is achieved by the application of a bent 21, Fig. 2, applied to the auxiliary brace 13.
  • the spreading force exerted by the brace 13 is, thereby, modified since the roof rib members during the shortening of the umbrella exert a pressure on the braces 10 whereby the auxiliary braces 13 are slightly bent. In this manner a contemporaneous extension of the stick members 1, 2 and of the roof rib members 8, 9 is produced as the latter are spread from the stick by the brace 13.
  • the retarding spring 17 need not be provided for every roof rod.
  • the embodiment of the invention shown in Figs. 5 and 6 is differentiated over those above described in so far as the auxiliary brace 22 is guided with its upper end along the upper rib 8.
  • a wire loop 23, Fig. 6, which embraces the roof rib, serves as a guide; this wire loop takes part in the displacement of the auxiliary brace 22.
  • .astick composed .of telescopically collapsible upper and lower stick members, a plurality of root ribs pivotally .connected to said stick and composed .of telescopically colapsibe upper and lower members, the upper end portion of said lower rib members being bent towards said stick, a wire spring fastened with its one end to the bent-ofl? portion of said lower rib member and slidingly positioned with its other end in the lower end portion of said upper rib member, said spring thereby exerting a resilient retarding action onto the mutual displacement of the upper and lower roof rib members.
  • a stick composed of telescopically collapsible upper and lower members, a plurality of roof ribs pivotally connected to said stick and composed of telescopically collapsibe upper and lower members, the upper end portion of said lower rib member being bent towards said stick, a wire spring having two shanks enclosing an acute angle therebetween being with the one shank movably connected with the bent-off portion of said lower rib member and being slidingly positioned with its'other shank along the lower end of said upper rib member said spring thereby exerting a resilient retarding action onto the mutual displacement of the roof rib members.
  • a stick composed of telescopically collapsible upper and lower .stick members, a plurality of roof ribs pivotally connected to said stick and composed of telescopically collapsible upper and lower rib sections, a wire spring inserted between the mutually contacting ends'o'f said roof rib sections, a bolt fastened to the upper end of the lower rib section, a spring fastened with its one end to said bolt and being with its other end slidably located in the roof rib section having the larger diameter.
