  • FIG. 5 is a top view of the contraption in accordance A device having a hollow pressure member including with the Second desigh Valuation,
  • Means are provided to move Wlth the thlrd deslgh Varlahoh,
  • FIG. 11 IS a side view of the contraption in accordance with a fourth design variation
  • FIG. 12 is a front view of FIG. 11 in the position providing for the largest volume between the suction BACKGROUND OF THE INVENTION and discharge phase,

  • FIG. 14 is a front view of the contraption in accordance with a sixth design variation.
  • Section 1, 2 is connected with section 3, 4 by way of This invention is applicable, for example, to provide hohding edges whereby Segments 2 4, P for a set of bellows which, at extensively simplified tlvely, are Connected Wlth each other y fleXlhg folds 6 structural arrangement, has a high efficiency rating and and, at bonding ges 8 by flexing folds, thus forming is able to produce a uniform air current attacking a a hollow body of Prlsmatle cross Seehonwhen 111 the wide area, position providing for the largest volume of the contraption, segments 1, 2, .3, 4 are each facing at an SUMMARY OF THE INVENTION angle of 90 degrees as is, for example, reflected in FIGS.
  • the extended ends of the bonding edges form This accelerating device for gaseous and liquid media the handles 9 which, by way of pulling or pressing is according to the invention featured by the fact that action, for the collapsing of the contraption across a parallelogram is intended to form the hollow body a median plane extending through handles 9 or across and pressure members, with the parallelogram made up a median plane extending vertically to the handles.
  • the of articulated angle sides with handles attached to at air present in the contraption is displaced by each of least two opposing joint locations, the angle sides of the two folding movements and is, for lack of back which, when in end position, lie fiat against each other, pressure, discharged to both sides.
  • backpressure diaphragm 10 is made up of a two-wing cardboard sheet collapsible across center fold 11, which is attached by way of the two bonding edges 12 at an angle of 45 degrees towards the articulated axles to the planes 3, 4.
  • the arrangement of the backpressure diaphragm 10, collapsible across center line 11, provides for the diaphragm to be flattened when handles 9 are pulled apart, and to be collapsed when handles 9 are pressed together, whereby the fiat as well as the collapsed position ofathe diaphragm and the position of largest volume of the contraption yield sufficient backpressure.
  • Successive pull-push-action at the handles 9 will produce a continuous air current, most useful to fan a wood or charcoal fire.
  • the outlet of the contraption to provide for the air exit is relatively large so that a wide area can be attacked by a uniform air current.
  • the production of this contraption of corrugated cardboard is highly economical, rendering it particularly useful for gift purposes or, because of the large printing surface area, advertising projects.
  • Design variation according to FIGS. to 7 forms a hollow body with a parallelogrammatic cross section with rectangular instead of trapeze-shaped segments 1, 2, 3, 4. This design avoids a reduction of the cross section of the air outlet, thus producing a more gentle air current.
  • FIGS. 8 to 10 show an extremely short version of the contraption which, in folded condition, requires a minimum of space and could, if intended to be used as a fan during the hot season, easily be carried in a ladys handbag.
  • FIGS. 11 and 12 The contraption shown in FIGS. 11 and 12 is designed to serve as a set of bellows to be made of high-grade wood, standard wood, plastic or synthetic material,'
  • the segments of the hollow body with the parallelogrammatic cross section can also be made of high-grade wood, standard wood, plywood, plastic or synthetic material, aerated hard-plastics components with protective coating etc. as is the case with design variations to FIGS. 11 and 12.
  • Hinges 25, 26 or 27, respectively, serve to provide articulated connection of segments 1, 2 and 3, 4, respectively, and the handle-halves 28, held together by screws 29. Handle-halves 28 are bonded together with glue or screws.
  • the design variation according to FIG. 14 differs from that shown in FIG. 13 in that the handles are made of one piece and the hinges between the handles and the segments are visibly screwed or riveted to the outside of the handles and segments. These visible portions of the hinges may be covered with trim strips.
  • At least the outer surfaces of the hollow bodies or the segments, respectively, i.e. 1, 2, 3, 4 and handles 9 could be coated with metal foil, aluminium for example, or with a suitable paint. Springs could also be fitted at the moving joints so as to simplify the opening and closing with the aid of elastic forces.
  • This accelerating device utilizable as a set of bellows is operated by pull-push-action with the aid of two opposing handles and is, thus, delivering a continuous air current. In collapsed condition, this contraption requires an insignificant amount of storage space in the baggage and is therefore given preference on walking tours.
  • this accelerating device when designed to serve as a blowing instrument or a set of bellows, should be given preference over conventional systems and is able to compete in places where luxurious models are in demand, namely in modern flats equipped with fireplaces.
  • the geometrically sober and clean design adds to the ornamental value of this invented bellows system.
  • This contraption could be designed into an attractive gift article.
  • the economy model made for example of corrugated cardboard, could be used as a very effective advertising means because of its large printable surface areas.
  • a further and ideal mode of application is provided by the collapsible character of the design in that this contraption could be used as a fan during the hot season.
  • the advantage of this set of bellows over conventional fans is, that it can be manually operated from lap level to provide a comfortable continuous air current.
  • this contraption could also be used in connection with water, either to produce a water current or, when equipped for backpressure with heart-type valves, as a swimming aid.
  • This heart-type valve should preferably be made up of at least one sail of synthetic material, coated fabric or any other type of suitable material.
  • the moving joints could also be designed as snap or pin joints which would offer particular advantages with models made of synthetic material.
  • a device for accelerating 'a fluid medium compris- (a) a hollow pressure member having four side segments which form a pressure chamber having a parallelogram shape in cross-section,
  • each said side segment being articulated with respect to the side segments adjacent thereto forming a collapsible and expandable pressure chamber
  • (c) means to move the articulated side segments with respect to each other for causing the movement of the fluid medium into and out of the pressure chamher
  • a diaphragm means disposed within said chamber and extending across at least a portion of the crosssec'tion of the pressure chamber.
  • each said side segment is composed of a flat segment and the flat segments are flexibly joined together along their edges.
  • a device as defined in claim 1 wherein said moving means includes handles oppositely disposed with respect to each other on the outside of said pressure member to manipulate the articulated sides.
  • said diaphragm means includes a two-wing sheet that is collapsible across a center fold.
  • said two-wing sheet includes two bonding edges which are attached to two adjacent articulated sides within the chamber,
  • said bonding edges extending in a direction at an angle of degrees with respect to the articulated edges of said two adjacent articulated sides whereby the twowing sheet moves from a folded position to a stretched flat position when the articulated sides are moved with respect to each other.
  • said hollow pressure member is composed of two corrugated cardboard sections,
  • each section includes two of the side segments joined together by a fold in the cardboard and one-half of handle members constituting the moving means located on opposed edges of the cardboard sections and being joined to the adjacent side segment by a fold in the cardboard,
  • handle member halves of one of the corrugated cardboard sections being bonded to corresponding handle member halves of the other cardboard section to form the hollow pressure member.
  • a device as defined in claim 1 wherein said diaphragm means is a back pressure valve that is formed by a heart-valve-type collapsible sail.
