Definitions
- the invention relates to a device for protection against slippage of soft material. More particularly, the invention relates to a protection device that can be used for preventing soft material located on a ground from slipping downstream.
- the invention finds particular application in the making of barriers designed to stabilize the snowpack in a detachment zone, thus preventing triggering of avalanches.
- This device substantially comprises a holding-back structure having oscillating arms hinged to a bracket attached to the main rod.
- a metal net is arranged on the arms.
- the structure can assume an open operative configuration or a closed, resting configuration. In the open configuration, the arms are substantially coplanar to one another and the net lies on a plane, whereas in the closed configuration the arms lie parallel to the main rod and the net is folded around the rod as happens with the fabric of an umbrella.
- the resting configuration is provided for facilitating transport of the device from the manufacturing or storage site to the site where the device is to be installed.
- metal ropes having the purpose of countering the thrust exerted against the net by the material to be retained.
- the ropes are attached to the distal ends of the arms and the central rod.
- a first object of the invention is therefore to provide a device of the umbrella-like type for retaining soft material, which does not exhibit the prior art drawbacks and is suitable for retaining material of various kinds, in particular snow.
- Another object of the invention is to solve the problem of how to obtain an umbrella-like device that can be easily transported and installed.
- the umbrella-like devices of the described type are intended for being mounted with their rod and ropes facing upstream, i.e. towards the side from which the material to be retained comes. Because of this arrangement, the ground located on the upstream side of the device is occupied by the rod and the ropes. In addition, the material retained by the device accumulates on the upstream side, thus covering the rod and the ropes.
- These known retaining systems are therefore unsuitable for being used for retaining soft material, which must be subsequently removed.
- the known devices are unsuitable for being repositioned after use. Indeed, the material that has accumulated on the rod and on the ropes frequently damages the device, thus jeopardizing the possibility of reusing it. Moreover, the removal of the material accumulated on the upstream side, which removal is usually effected with mechanical means, almost always causes damages to the structure of the device.
- a further object of the invention is therefore to overcome the problem of how to make an umbrella-like device of the aforementioned type reversible, i.e. usable both with the central rod oriented upstream and with the central rod oriented downstream.
- Another object of the invention is to provide a device of the aforementioned type that is strong and reliable and can possibly be repositioned even several times after each use, if necessary.
- An additional object of the invention is to provide a protection device that is easy and quick to install.
- a not least object of the invention is to provide a protection device which is adapted to be industrially manufactured on a large scale.
- the device according to the invention is capable of assuming a closed or resting configuration and an open or working configuration.
- the closed configuration is of advantage for transport and storage of the device.
- the device comprises a substantially rectilinear longitudinal rod provided with first anchoring means for anchoring to the ground.
- the rod is preferably arranged centrally in the device and the first anchoring means are arranged at one of the ends of the rod.
- Anchoring of the device to the ground can be effected for instance by means of at least one anchoring guy wire penetrating deeply into the ground.
- the device further comprises oscillating arms, preferably four in number.
- the arms can assume a resting configuration and a working configuration. When the arms are in the resting position, the angle formed by the arms and the rod is smaller than the angle formed by the arms and the rod when the arms are in the working position.
- the arms assume an arrangement approximately parallel to the rod when they are in the resting position and an arrangement approximately perpendicular to the rod when they are in the working position.
- the rod advantageously comprises a slider that can slide along at least part of the rod.
- the slider comprises rotatable engaging means for the oscillating arms.
- the rotatable engaging means allow the arms to oscillate on a plane parallel to their axis and consist preferably of hinge pins.
- the rod may consist for instance of a tube having a cylindrical or square cross-section or of a profile with substantially any cross- section shape.
- the slider is preferably a sleeve surrounding the rod or it may consist of a carriage slidable along a seat provided in the rod. According to the invention, the slider can slide between a position proximal to the first anchoring means and a position distal relative to said first anchoring means. The proximal position corresponds to the resting configuration of the oscillating arms and the distal position corresponds to the working configuration of said arms. Still according to the invention, for each arm there is provided a rope attached to an arm and to the rod. The upstream ropes are attached to their respective arms at a distance from the slider of approximately 2/3 of the length of the arm. The upstream rope is also preferably attached to the rod near or at the first anchoring means.
- This rope is referred to as upstream rope because it faces that side of the device which, in a preferential, though not exclusive, way, faces upstream of the arms relative to a slope on which the device is installed.
- this rope is referred to as downstream rope, as it faces that side of the device which, in a preferential, though not exclusive, way, faces downstream of the arms relative to a slope on which the device is installed.
- the ropes are in a released configuration when the arms are in the resting configuration and are tensioned when the arms are in the working configuration.
- a flexible net can advantageously be provided on the arms in order to define a substantially planar surface for retaining the material so as to prevent slippage thereof downstream of the device.
- both ends of the rod are provided with anchoring means and the device can therefore advantageously be installed with either of the anchoring means arranged upstream of the arms.
- the device 11 comprises a substantially rectilinear longitudinal rod 13.
- the rod 13 is arranged substantially centrally in the device 11.
- First anchoring means 15' for anchoring the device to the ground are provided at one of the ends of the rod 13.

Description
- The invention relates to a device for protection against slippage of soft material. More particularly, the invention relates to a protection device that can be used for preventing soft material located on a ground from slipping downstream. The invention finds particular application in the making of barriers designed to stabilize the snowpack in a detachment zone, thus preventing triggering of avalanches.
- Within the field of devices for protection against slippage of soft material it is known to use structures of different kinds, for instance comprising modular elements that are made of a metal mesh and are provided with supporting poles, usually anchored to a basement provided in the ground. The modular elements usually consist of metal beams connected to one another so as to form a supporting frame for the metal net. The modular elements are usually assembled directly at the site of the final installation. This technique requires long installation times and therefore is unsuitable for creating barriers quickly, for example in case of emergencies. In the past, protection devices were developed that were capable of assuming a resting or transport configuration and a working or operative configuration. These devices are essentially made in the form of umbrellas. An example of a known device of this type is described in
WO2011117790 (A1 ). This device substantially comprises a holding-back structure having oscillating arms hinged to a bracket attached to the main rod. A metal net is arranged on the arms. The structure can assume an open operative configuration or a closed, resting configuration. In the open configuration, the arms are substantially coplanar to one another and the net lies on a plane, whereas in the closed configuration the arms lie parallel to the main rod and the net is folded around the rod as happens with the fabric of an umbrella. - The resting configuration is provided for facilitating transport of the device from the manufacturing or storage site to the site where the device is to be installed. In this kind of devices, between the oscillating arms and the rod there are further provided metal ropes, having the purpose of countering the thrust exerted against the net by the material to be retained. The ropes are attached to the distal ends of the arms and the central rod.
- However, the devices of the kind described above require use of particularly strong structural elements made of steel, which increase the weight thereof. A first object of the invention is therefore to provide a device of the umbrella-like type for retaining soft material, which does not exhibit the prior art drawbacks and is suitable for retaining material of various kinds, in particular snow. Another object of the invention is to solve the problem of how to obtain an umbrella-like device that can be easily transported and installed.
- The umbrella-like devices of the described type are intended for being mounted with their rod and ropes facing upstream, i.e. towards the side from which the material to be retained comes. Because of this arrangement, the ground located on the upstream side of the device is occupied by the rod and the ropes. In addition, the material retained by the device accumulates on the upstream side, thus covering the rod and the ropes. These known retaining systems are therefore unsuitable for being used for retaining soft material, which must be subsequently removed. Furthermore, due to this arrangement, the known devices are unsuitable for being repositioned after use. Indeed, the material that has accumulated on the rod and on the ropes frequently damages the device, thus jeopardizing the possibility of reusing it. Moreover, the removal of the material accumulated on the upstream side, which removal is usually effected with mechanical means, almost always causes damages to the structure of the device.
- A further object of the invention is therefore to overcome the problem of how to make an umbrella-like device of the aforementioned type reversible, i.e. usable both with the central rod oriented upstream and with the central rod oriented downstream.
- Another object of the invention is to provide a device of the aforementioned type that is strong and reliable and can possibly be repositioned even several times after each use, if necessary.
- An additional object of the invention is to provide a protection device that is easy and quick to install. A not least object of the invention is to provide a protection device which is adapted to be industrially manufactured on a large scale.
- The aforementioned and other objects are achieved with the device for protection against slippage of soft material as claimed in the appended claims.
- The device according to the invention is capable of assuming a closed or resting configuration and an open or working configuration. The closed configuration is of advantage for transport and storage of the device. According to a preferred embodiment of the invention, the device comprises a substantially rectilinear longitudinal rod provided with first anchoring means for anchoring to the ground. The rod is preferably arranged centrally in the device and the first anchoring means are arranged at one of the ends of the rod. Anchoring of the device to the ground can be effected for instance by means of at least one anchoring guy wire penetrating deeply into the ground.
- The device further comprises oscillating arms, preferably four in number. The arms can assume a resting configuration and a working configuration. When the arms are in the resting position, the angle formed by the arms and the rod is smaller than the angle formed by the arms and the rod when the arms are in the working position. In a preferred embodiment of the invention, the arms assume an arrangement approximately parallel to the rod when they are in the resting position and an arrangement approximately perpendicular to the rod when they are in the working position. According to the invention, the rod advantageously comprises a slider that can slide along at least part of the rod. The slider comprises rotatable engaging means for the oscillating arms. The rotatable engaging means allow the arms to oscillate on a plane parallel to their axis and consist preferably of hinge pins. The rod may consist for instance of a tube having a cylindrical or square cross-section or of a profile with substantially any cross- section shape. The slider is preferably a sleeve surrounding the rod or it may consist of a carriage slidable along a seat provided in the rod. According to the invention, the slider can slide between a position proximal to the first anchoring means and a position distal relative to said first anchoring means. The proximal position corresponds to the resting configuration of the oscillating arms and the distal position corresponds to the working configuration of said arms. Still according to the invention, for each arm there is provided a rope attached to an arm and to the rod. The upstream ropes are attached to their respective arms at a distance from the slider of approximately 2/3 of the length of the arm. The upstream rope is also preferably attached to the rod near or at the first anchoring means.
- This rope is referred to as upstream rope because it faces that side of the device which, in a preferential, though not exclusive, way, faces upstream of the arms relative to a slope on which the device is installed. For each pair of adjacent arms, at least one rope attached to both arms of each pair is further provided. For the same reasons set forth above, this rope is referred to as downstream rope, as it faces that side of the device which, in a preferential, though not exclusive, way, faces downstream of the arms relative to a slope on which the device is installed. According to the invention, the ropes are in a released configuration when the arms are in the resting configuration and are tensioned when the arms are in the working configuration. A flexible net can advantageously be provided on the arms in order to define a substantially planar surface for retaining the material so as to prevent slippage thereof downstream of the device.
- In an embodiment variant, both ends of the rod are provided with anchoring means and the device can therefore advantageously be installed with either of the anchoring means arranged upstream of the arms.
- Some preferred embodiments of the invention will be described by way of non-limiting examples with reference to the annexed drawings, in which:
- 1a
Fig.1 is a plan view of the device when closed; - 1a
Fig.2 is a plan view of the device ofFig. 1 when partially open; - 1a
Fig.3 is a plan view of the device ofFig. 1 when open; - 1a
Fig.4 is a schematic front view of the device ofFig. 1 when open. - Referring to
Figs. 1 to 3 , there is illustrated a preferred embodiment of the device for protection against slippage of soft material according to the invention. The device has been indicated as a whole withreference numeral 11. Thedevice 11 comprises a substantially rectilinearlongitudinal rod 13. Therod 13 is arranged substantially centrally in thedevice 11. First anchoring means 15' for anchoring the device to the ground are provided at one of the ends of therod 13. In the illustrated embodiment, therod 13 is made of steel and has a square cross-section. Other materials, such as steel alloys, as well as other cross-sections, such as circular or oval cross-sections, are in any case possible. The first anchoring means 15' comprise abracket 17 fixed, for instance by welding, to one of the ends of therod 13. Thebracket 17 comprises at least onehole 17a, two holes in the shown example, for passage of a corresponding fixing bolt for fixing said bracket to a basement provided in the ground for securing thedevice 11 in its working condition. Thedevice 11 further has fouroscillating arms 19. Thearms 19 can oscillate so as to assume a resting configuration (Fig.1 ) and a working configuration (Fig.3 ). In the resting configuration thearms 19 form with therod 13 an angle α smaller than the angle β formed when thearms 19 are in their working configuration. The resting configuration corresponds to the configuration in which thedevice 11 is closed and the working configuration corresponds to the configuration in which thedevice 11 is open. According to the invention, the angle α preferably ranges between 0 and 30° and still more preferably between 0 and 20° and the angle β preferably ranges between 60 and 100° and still more preferably is approximately 80°. Thedevice 11 further comprises aslider 21 slidable along at least part of therod 13. Theslider 21 is provided with rotatable engaging means 23 for thearms 19. In the illustrated example, said means 23 comprisehinges 23a welded to theslider 21 and provided with hinge pins 23b passing transversely through thearms 19. Theslider 21 is adapted to slide between a position proximal to said first anchoring means 15' and corresponding to the resting configuration of thearms 19 and a position which is distal relative to said first anchoring means 15' and corresponds to the working configuration of saidarms 19. In the illustrated embodiment, theslider 21 comprises asleeve 25 surrounding therod 13. Thesleeve 25 can be locked to therod 13 by means of radial screws 26. Corresponding bores for engagement of the radial screws 26 can further be provided along one of the generatrices of therod 13. - Each
arm 19 is provided with arope 27 attached at its one end to thearm 19 and at its opposite end to therod 13. Thisrope 27 is referred to as upstream rope because it is arranged upstream of thearms 19 when thedevice 11 is installed on a slope and therod 13 is arranged parallel to the slope line with the first anchoring means 15' arranged upstream. One of the ends of therope 27 is attached to therod 13 near or at the first anchoring means 15' and the other end of therope 27 is attached to thecorresponding arm 19 at a distance from theslider 21 of approximately 2/3 of the length of thearm 19. For each pair ofadjacent arms 19 at least onerope 29 attached to botharms 19 of each pair is further provided. Thisrope 29 is referred to as downstream rope because it is arranged downstream of thearms 19 when thedevice 11 is installed in the manner set forth above. Theropes arms 19 are in the resting configuration and are tensioned when thearms 19 are in the working configuration. Theropes arms 19 and to therod 13 by known means, for example by means of threadedbolts 31a secured inbrackets 31b welded to thearms 19 and to therod 13. Theropes thimble 33a and arope clamp 33b for passage of the threaded bolts. Preferably, an shackle-like element 31c is provided between thebolts 31a and the corresponding thimble. Theropes - As better visible in
Fig.4 , the illustrated embodiment comprises twoupstream ropes 29 for each pair ofadjacent arms 19. A net 35 is further arranged on theropes 29 and attached to thearms 19. When thedevice 11 is installed on a ground, for instance a mountain slope, theropes 27 define, together with the net 35 and thearms 19, a protective structure for preventing soft material located on a ground, such as in particular snow or ice, from slipping downstream. - Referring again to
Figs. 1 to 3 , second anchoring means 15" for anchoring to the ground, substantially identical to the first means 15', are preferably provided at the opposite end of therod 13 for allowing mounting of thedevice 11 rotated of 180° with the second means 15" upstream of thearms 19. This second arrangement causes the downstream ropes to be positioned upstream and theupstream ropes 27 to be positioned downstream. This second arrangement allows to bear a load usually smaller with respect to the first arrangement in which the first anchoring means 15' are arranged upstream of thearms 19. - The invention as described and illustrated is susceptible to several variations and modifications, falling within the same inventive principle.
