Definitions

  • At least one and preferably a plurality of flexible elongated elements such as wires or tapes extend from the lower cross piece-of the first frame up to the upper cross piece of the second frame from which the elements are redirected to the lower cross piece of the second frame and then upwardly to the upper cross piece of the first frame. These elements permit expansion of the frame and the slack therein is taken up as the frame contracts in size.
  • Each frame has associated therewith a wall member preferably mounted' on the outer side of the upper cross piece of each frame, these wall members being vertically adjustable and adapted to be urged against the freight being braced by the present apparatus.
  • FREIGHT BRACE At present, inflatable cushions are used to a great extent for bracing freight in cargo cars such as railway cars, automobiles, boats, containers and so on. These cushions are mounted in spaces between the different freight units. A certain insecurity will exist, however, due to the risk of leakage of the air from the cushions during transporation. Another disadvantage is the need for a source of air under pressure.
  • US. Pat. No. 3,472,180 shows a normally stationary but adjustably movable wall, by means of which one may vary and change the interior space in for instance a cargo car so that no unnecessary spaces exist in the load with the attendent danger of displacement such as by rolling upon sudden changes of movement such as by damage to the transportation vehicle.
  • US. Pat. No. 1,708,413 another more portable solution to the problem is shown for keeping apart different freight units, such as for instance different cases in a freight space, and in US. Pat. No. 3,33,553, a scissor like arrangement is shown, which is pressed apart by turning movement around a screw by means of a crank.
  • the present invention relates to a solution of the problem of creating a freight brace, which in the first place builds upon the scissors idea but which has a plurality of contact points and a great stroke length, which may be easily changed by means of a system of wires or straps with a stop arrangement for fixation of the scissors in the desired position.
  • the present invention thus relates to an arrangement to bring apart and/or fixedly position two vertical, displaceable wall elements a desired distance from each other, said arrangement comprising one first and one second frame, each per se substantially enclosed within a surrounding rectangle.
  • Each frame includes one upper and one lower cross piece and at least one long piece connecting said cross-pieces, whereby the mid points of the long pieces of the two frame constructions are pivotably combined by means of bolts or the like running through them so that a scissor like or folding chair like apparatus is obtained.
  • a group of wire or tape elements extends from attachments in the upper cross piece of the first frame, around re-directional rollers or around suitable guiding means in the lower cross piece of the second frame, into and through the interior of the upper cross piece of the second frame and finally I out of that cross piece and downwardly to two attachments in the lower cross piece of the first mentioned frame.
  • Arrangements are further provided for shortening or extending the wire or tape elements in order to adjust the stroke length' of the scissor-like bracearrangement, i.e., the width in the horizontal direction, thereby tightening said systems between the upper cross piece of each frame and the lower cross piece of the opposite frame.
  • FIG. 1 is a perspective view of the arrangement according to one embodiment of the invention, whereas FIG. 2 and FIG. 3 show in schematic form the function of said arrangement.
  • FIG. 4 shows on an enlarged scale, a detail of the arrangement according to FIG. 1.
  • FIG. 5 is a perspective view of a second embodiment, and FIGS. 6 and 7 show in two different positions an auxilliary arrangement for use in the freight brace according to the embodiment of FIG. 5, when the horizontal distance between the sides of the freight brace is very small.
  • the last mentioned arrangement can also be used in the embodiment of FIGS. 1 3.
  • the two frames comprise closed rectangular frames, one frame comprising a couple of long pieces 10 and 11 and a couple of cross pieces 14 and 15 and the other having long pieces 12 and 13 and cross pieces 16 and 17.
  • One of these cross pieces, namely the cross piece 15, is totatably mounted in the ends of the corresponding long pieces 10 and 11.
  • the frames are pivotably connected together by means of bolts 18, 18, running through the middle points of the long pieces 10 and 12 or 11 and 13, resp.
  • one single bolt may be used, running through both pairs of long pieces through holes, shown in FIG. 1, so that a scissor construction is formed.
  • a couple of steel wires 19, 20, attached to the upper cross piece 16 of the first frame are directed over a couple of directional rollers 21, 22 connected to the lower cross piece 14 of the second frame. Thereafter they run through holes 211 and 24 in the tube-formed, turnable cross piece 15 in the same frame, in directions opposite to each other through the interiorof this cross piece 15 and out through openings 23, 221 in the cross piece 15, whereafter they continue to the lower cross piece 17 of the first mentioned frame.
  • a wire 68 is arranged between the two upper cross pieces 16 and 15 to prevent collapse of the scissors, when not used in its stretched position.
  • the turnable cross piece 15, which, as mentioned above, is tube-formed, is provided at its one end with a crank 26, comprising a bar with two handle balls.
  • the bar of said crank may be displaceably arranged within the tube, so that in each of the extended positions the one handle ball will contact the tube 15 as a stop means, whereas the other handle ball will be situated at the fartherest possible distance from the tube 15 thereby forming a long lever arm when turning the tube 15.
  • a stop arrangement is applied in connection with the crank, which will be more clearly shown in the section view according to FIG. 4.
  • a rubber block 27 in the interior of tube 15 acts as a contact spring for a stop arm 28 mounted inside of the tube 15 and is tumable about a pin 29, the free end of said stop arm being in contact with a saw tooth formed ring 30, which simultaneously forms a bearing for one end of the tube 15.
  • the arm 28 can be drawn out from this stop position in engagement with the ring 30 by means of a drawing means 31 such as a wire or the like.
  • each frame On the outside of each frame a plate 32, 33 is provided, preferably reinforced by a couple of braces 34, 34.
  • This plate is movable vertically to a lower or a higher position by means of a wire construction, separate from the above mentioned wire construction, and comprising a wire 35, (see FIG. 4.)
  • a wire lock 36 One end of this wire is attached to the plate 32 by means of a wire lock 36 and its other end is attached to the same plate 32 by means of a wire lock 37.
  • the wire 35 runs through the eyelet 38 ofa bolt 39 and includes at least one turn around the ring 30.
  • the bolt 39 runs through two openings 40, 41 in the long piece 11, and at its opposite end it is provided with a nut 42.
  • a similar wire construction suitably is arranged at each of the other long pieces 10, 12 and 13.
  • clamps 43 are providedclose to the lower edge of each of the two plates, and the wires 19, 20 run through said clamps.
  • each plate is adjusted shortly before a hard contact pressure has been created by releasing the clamping of the wires by releasing the nuts 42.
  • the nuts 42 are again locked, so that eyelets 38 will be drawn inwardly against their respective openings and the wires 35 will be stretched, thereby locking the plates in their adjusted vertical positions.
  • the two long pieces 10 and 11 are replaced by one single long piece 481, and the two long pieces 12 and 13 are, in a corresponding way, replaced by one single long piece 49.
  • Each long piece 49, 481 is provided at its upper end with a cross piece 52, 53, respectively, and at its lower end with a cross piece 54, 55, respectively.
  • the 6 wires 19 and 20 have been replaced by belts 56 and 57, respectively. These are extendable or shortenable by means of belt spanners 58 and 59, respectively, known per se, for instance as in tape spanners for travellers luggage and the like.
  • Clamps 60 have been provided at the lower edges of the plates 61 and 62 in the same way as the clamps 43 in the arrangement according to FIG.
  • FIGS. 6 and 7 show schematically two different ways of using the arms 63 and 64.
  • the arms are brought into a position forming an obtuse angle in which the arms are indicated by 63 and 64, whereafter a bolt has been introduced, for instance at the place 69.
  • a bolt has been introduced, for instance at the place 69.
  • the arms are thereafter pressed downwardly by hand into the positions 63 and 64, resp., they are separated, and they will create the desired separation force.
  • the two arms are instead positioned downwardly into the position 63" and 64" respectively and held by a bolt at the place 69.
  • the arm 63 also has another function.
  • the distance between the plates 61 and 62 is so great that there is no need for using the arms 63 and 64 for obtaining a separation force, one may by turning the arm 63 downwardly and connecting it to the long piece 49, on which there is for this purpose an eyelet, provide an additional force for pressing the plates 61 and 62 apart, which will in many cases be useful.
