Description

PIPE HOLDING DEVICE
AND USE OF THE DEVICE
The present invention relates to a hose holding device which can be used in particular as a fire hose holding device.

 The maintenance by an individual of a hose projecting a liquid, which is generally water under pressure, is often difficult. Firefighters particularly feel this difficulty by holding a fire hose fitted with a lance. Indeed, such a pipe is heavy, rigid, slippery and its outside diameter does not allow it to be gripped easily by hand. In addition, when operating with a water pressure of up to 15.105 Pa, maintaining the hose requires several people to resist the recoil force of the jet, which unnecessarily exposes these people to danger. This results in the lance firefighter who is responsible for directing the jet having to spend a lot of energy to resist the recoil force which makes the action of directing the jet of water even more difficult. pipe retention is further increased when it has to go through stairs or when the firefighter carries lance has to intervene from the top of a ladder.

 US Pat. No. 4,770,177 has proposed a holding device for fire hose consisting of a sleeve formed by two half-shells articulated by means of a hinge placed according to a generator and locked, after fitting of the hose. , by a hook system driven by a lever, each half-shell being provided with a handle.

 This holding device can give satisfaction but it has drawbacks. Indeed, it is of complex construction which can be a source of deterioration and moreover its installation requires to open the locking system, to separate the half-shells, to place the pipe, to close and lock the half-pieces shell operations which cause a loss of time for firefighters.

 The present invention relates precisely to a pipe holding device which avoids these drawbacks.

 An object of the invention is a holding device which is of robust construction.

 Another object of the invention is a holding device which is set up, on a pipe, easy and quick.

 Yet another object of the invention is a holding device particularly intended to be used for holding a fire hose.

 A holding device for pipe has now been found, characterized in that it consists of a one-piece, substantially cylindrical sleeve comprising a longitudinal slot and gripping means integral with the sleeve.

 In the present text by "one-piece sleeve" is meant that the sleeve does not have moving parts with respect to each other. This does not exclude that the sleeve can be constructed with several assembled parts and includes, for example, screwed, bonded, welded, riveted or even riveted reinforcing structures.

 By "longitudinal slot" is meant in the present text that the slot is placed on the sleeve so that its length is substantially in the longitudinal direction of the pipe.

 Preferably, in order to ensure effective contact between the pipe and the sleeve, the sleeve is of circular internal section.

 More preferably, for convenience of placing the device on a pipe, the longitudinal slot is located along a generatrix of the sleeve. This particular arrangement allows, easily, to slide the pipe before its impoundment -it is then flattened by the longitudinal slot inside the sleeve.

 So that the holding device can be effectively gripped by hand, the gripping means are formed by at least one handle of the handle type.

 Advantageously, the holding device is such that the gripping means are formed by two handles of the handle type.

 The handle or handles can be made integral with the sleeve by any suitable means. Depending on the nature of the materials constituting the sleeve and the handle or handles, they can be screwed, riveted, glued, or even welded to the sleeve.

 Preferably, the gripping means and the sleeve are made in one piece, so the holding device, object of the invention, can be obtained by molding.

 The device according to the invention can be made of various metallic or non-metallic materials. Advantageously, the device is made of plastic. Plastics with good mechanical properties and impact resistance are particularly advantageous, so the device can be made of thermoplastic polymers such as polyamides, polyesters, polycarbonates, polyacetols, polyolefins, optionally comprising reinforcing agents.

 According to one embodiment, the device according to the invention can be such that it includes a pad placed inside the sleeve. This pad can be made of a more flexible material than the material constituting the sleeve in order to avoid any damage to the pipe. The bearing obviously has a longitudinal slot similar to that of the sleeve.

 The bearing can be force-fitted into the sleeve, it can also be made integral with the latter by gluing.

 The bearing, according to an alternative embodiment, can be such that it is movable in rotation in the sleeve, it is then provided with stop rings preventing any longitudinal displacement.

 The pipe holding device object of the invention can be used whenever it is necessary to manually hold a pipe. The device is particularly intended to be used as a device for holding a fire hose.

 The invention will be better understood from the description of the attached figures which schematically illustrate, by way of example, and without a determined scale, various embodiments of the device for holding a pipe, object of the invention.

 Figure 1 is a general view of an embodiment of the device according to the invention.

 FIG. 2 is a view in section through the plane II Il of the device according to the embodiment shown in FIG. 1.

 Figure 3 is a general view of another embodiment of the device object of the invention.

 FIG. 4 is a view in section through the plane IV IV of the device according to the embodiment shown in FIG. 3.

 Figure 5 is a sectional view through a plane perpendicular to the axis of the sleeve of another embodiment of the device.

 Figure 6 shows the use of the hose holding device, object of the invention, for holding a fire hose.

 An embodiment of the holding device (1) according to the invention is shown in Figure 1 in external general view in place on a pipe (2) and in section through a plane II II, perpendicular to the axis of the pipe, on the figure 2.

 The device (1) consists of a one-piece sleeve (3) and gripping means (4) integral with the sleeve (3).

 The sleeve (3) is substantially cylindrical with a circular internal section of a diameter substantially equal to the external diameter of the pipe for which it is intended. The sleeve (3) is formed in one piece and has a longitudinal slot (6) placed along a generatrix of the sleeve (3). The edges (7) of the edges of the slot (6) are blunted so as not to damage the pipe (2).

 The gripping means (4) are constituted by a handle (5) of the handle type, the shape of which is well adapted to be gripped firmly by one hand. The handle (5) is integral with the sleeve (3), the handle (5) and the sleeve (3) are, according to this embodiment, made in one piece.

 A device according to this embodiment can be easily obtained by molding, in particular of plastic material, for example by molding of polyamides.

 Such a holding device (1) is easy to set up.

When a fire hose (2) is not connected to a liquid supply source, it is in flattened form. The holding device (1) is then placed on the pipe (2) by sliding the latter through the slot (6) inside the sleeve (3). When the hose is pressurized with liquid, it swells and has a circular section which fills the interior space of the sleeve (3). Due to the pressure inside the pipe (2) it is pressed against the inner surface of the sleeve (3), the holding device (1) is then securely attached to the pipe (2).

Disassembly will be just as easy after draining the hose (2).

 The holding device (1) according to the embodiment shown in FIGS. 3 and 4 comprises gripping means (4) formed by a handle (5) of the handle type which comprises fixing lugs (8) intended to make it possible to secure the handle (5) to the sleeve (3) for example by means of screws (9).

 Depending on the type of material used to make the handle (5) and the sleeve (3), the fixing lugs (8) can be made integral with the sleeve (3) by welding.

 The device (1) according to this embodiment comprises a pad (10) placed inside the sleeve (3). The bearing (10) has a slot (11) intended to allow the introduction of the pipe (2) during assembly. The slot (11) is substantially along a generatrix of the pad (10) and of a width corresponding to that of the slot (6) of the sleeve (3).

 The bearing (10) according to the present embodiment can rotate inside the sleeve (3) to occupy the position shown in FIGS. 3 and 4, which prevents any exit of the pipe (2) when it is not not under liquid pressure, which is possible when the slots (6) of the sleeve (3) and (11) of the pad (10) are in coincidence. The pad (10) is of course made of a material such that the pressurization of liquid from the pipe (2) causes a radial deformation of the pad (10) thus blocking it inside the sleeve (3).

 So that the bearing (10) cannot move longitudinally in the sleeve (3), stop rings (12) of a usual type are placed in grooves provided for this purpose on the outer surface of the bearing (10 ).

 The holding device according to the embodiment shown in Figure 5 comprises gripping means (4) formed of two handles (5, 13) of the handle type. It also includes a pad (10) placed inside the sleeve (3), the pad (10) being force fitted is not movable in rotation.

 FIG. 6 illustrates the use of the holding device (1), object of the invention, as a device for holding a fire hose (2) provided with a lance (14). As can be seen during the fight against a fire, the firefighter serving (15) holds the hose (2) by means of the device (1) object of the invention, the firefighter carrying lance (16) can then devote himself entirely to the operation of the lance (14) to direct the water jet effectively.

 Of course, the invention is in no way limited to the embodiments described specifically in the present description and it is possible to adopt variants or improvements without departing from the scope of the invention.

 The holding device which is the subject of the invention has numerous advantages.

 Indeed, on the one hand it is simple and robust and, on the other hand, by design it is easy to set up.

 The holding device also has the advantage of allowing effective maintenance by an individual of a pipe conveying a pressurized liquid, in particular a fire hose.
