Abstract

It comprises a vertical disc (1) mounted so that it can pivot on a horizontal rotation spindle (12) located inside a hollow cylinder (31) integral with a frame, the said disc (1) and the said rotation spindle (12) having two extractable cylindrical parallel fingers (21) integral with a manually actuatable crank (2) passing axially through them, and a support (5) which can be secured to the frame fitting on facing the front face of the disc (1) from which the fingers (21) project, leaving a space of a width slightly greater than that of the hose to be wound up.

Description

The present invention relates to a device for winding long objects

and flattened, such as pipes

soft fire or straps.

  Generally, long and flattened objects, such as flexible fire hoses or straps used in particular on transport vehicles to hold goods, are preferably, after use,

  coiled to reduce their bulk.

  This winding operation is difficult to perform manually, especially because of the weight of

some of these objects.

  Already known devices for winding flexible fire hose, especially in fire stations, but they are of significant size and can hardly be transported by

  example at the scene of a disaster.

  The present invention aims to remedy this deficiency by proposing a winding device of long and flattened objects, which offers the advantage of a clutter

  reduced and easy handling.

  For the sake of simplification and clarity the

  following description is applied to the winding of a

  hose of the fire hose type, but it goes without saying

  that it can concern any other object long and flattened.

  The device according to the invention is essentially characterized in that it comprises a vertical disk pivotally mounted on a horizontal axis of rotation disposed in a hollow cylinder integral with a frame, said disk and said axis of rotation being traversable axially by two extractible cylindrical parallel fingers,

  secured to a manually operated crank.

  According to the invention the crank comprises two parts, a first part at one end of which are secured the two parallel fingers, and a second portion pivotally mounted approximately at its middle, at the other end of the first, around a pivot axis, one end of which has a handling handle and the other a parallel axis rolling roller

said pivot axis.

  Still in accordance with the invention, a support that can be fixed to the frame fits on the face of the disc from which the parallel fingers project, leaving between the disc and said face a space of slightly width.

  greater than that of the hose to be wound.

  The winding of a pipe is made by folding it by its middle and by engaging it, at the central fold thus formed, between the two parallel fingers, the rotation of said fingers, driven by the crank, causing the winding of said pipe between the disc and the support. When the pipe is completely wound, inside the support, or extract the two fingers of the disk by exerting traction on the pivoting portion of the crank used as a lever by pressing on the disk surface by the end provided with the roller. The wound pipe then falls into the support which is disengaged from the frame, the pipe remaining inside the support, and an empty support, or the same emptied of its contents, can be then

  secured to the frame for winding another pipe.

  In order to facilitate the extraction of the fingers of the wound tube, because of the pressure exerted by the latter, the end of each of the fingers may be

advantageously conical.

  On the other hand, in order to take the least possible space, especially in the case of a winding device of a fire hose, the frame can be foldable, which allows the introduction of the entire device in a standard size intervention box that firefighters

usually use.

  The advantages and features of the present invention will emerge more clearly from the

  description which follows and which refers to the annexed drawing,

  which represents a non-limiting embodiment thereof.

  In the appended drawing: FIG. 1 represents a perspective view

  of a retractor device according to the invention.

  - Figure 2 shows a partial perspective view, seen from another angle and exploded, the same device. FIG. 3 represents a partial diagrammatic view, seen from the front, of the same device on which

wound a pipe.

  With reference to FIGS. 1 and 2, it can be seen that the device according to the invention comprises a vertical disk 1 secured at its center to an axis 12 mounted in free rotation in a horizontal hollow cylinder 31 integral with a vertical telescopic rod 3 a foldable chassis 4, two parallel cylindrical orifices 121 formed in the axis 12 being intended to receive two fingers 21

secured to a crank 2.

  The crank 2 comprises a piece 22 of L-shaped section, at the end of one of the branches of which are secured the two parallel fingers 21, and comprises a central cavity 23 allowing an arm 24 to pivot, approximately in its middle, about a transverse axis 25. The arm 24 has at one of its ends a handle 26 of cylindrical shape and at its other end a roller of

  bearing 27 of axis of rotation 28 parallel to the axis 25.

  It is also possible to see a support 5 comprising a portion 50 bent in a U-shape, one branch 51 of which is intended to be introduced into one of two vertical tubes 32 secured peripherally to the cylinder 31 aligned according to the upper generatrix thereof, and the other 52 is extended in the same plane, two V branches 53 and 54 whose ends respectively 55 and 56 are bent at right angles parallel to the branch 57 connecting the

branches 51 and 52.

  So when the support 5 is in place, that is

  that is to say, when the portion 50 is positioned astride the disk I, there remains between the branches 52, 53 and 54, and the front face 13 of the disk 1 a space limited below by the folded ends 55 and 56, and a thickness slightly greater than the width of the pipe to be wound, the choice to introduce the branch 51 in one or the other of the vertical tubes 32 depending on the width of the pipe to be wound, knowing that there are two standard widths of fire hose. If we now refer to Figure 3 we can

  see a pipe 6 wound against the front face 13 of the disk 1.

  The winding of a pipe 6 is made by first folding it in its middle 60 and then engaging it, at the level of the central fold thus formed, between the two fingers 21 of the crank 2, the rotation of the by means of the handle 26 causing the fingers 21 to rotate, causing the hose 6 to wind on itself

  the face 13 of the disc 1 and the part 53 of the support 5.

  When the pipe 6 is completely wound, the two fingers 21 are removed from the axis 12 of the disk I by exerting traction on the arm 24 used as a lever, the end provided with the roller 27 taking a rolling bearing on the rear face 14 disk i. The pipe 6 then falls on the disposed ends 55 and 56 of the support 5 which is detached from the frame 4 by removing the branch 51 of the tube 32 where it has been engaged, and an empty support can then be

  secured to the frame 4 for winding another pipe.

  It goes without saying that the present invention

  could be limited to the foregoing description of one of

  its embodiments, capable of undergoing a number of modifications without departing from the scope of the invention.
