Definitions
- the present invention relates to a locking and ascent device for climbs by means of ropes, strings, and the like.
- the conventional locking and ascent devices generally comprise a body in which there is provided a seat for housing either a rope or an element equivalent thereto (a string, a cable, etc.) and a locking element, typically a tooth.
- the locking tooth is movable between a releasing position with the rope and an engaging position with the latter.
- the locking tooth engages the rope by clamping the latter and preventing that the latter may slide within its respective seat solely along a predetermined direction, generally the descent one causing the device to move downwards along the vertically extending rope.
- the tooth will release the rope, thus allowing the latter to slide within its seat.
- the conventional devices are usually provided with a handle for the climber and a spring having the function of bringing the locking tooth, following a movement of the same, back in contact with the respective rope.
- the locking tooth is usually rested on the rope housed in the seat.
- a conventional device may slide on the rope in the direction allowed, with the locking tooth which does not interfere with the rope movement.
- the locking tooth is usually fastened to a safety lever to be manually operated by the climber.
- the safety lever allows the climbing user to intentionally unfasten the locking tooth from the rope, the latter being thereby brought to the releasing position.
- a drawback with the conventional locking and ascent devices is that the safety lever is often difficult to operate by the climber. In fact, this lever is usually operated through the thumb of the hand with which the user manoeuvres the respective locking and ascent device. The movement to be performed by the user is not easy and does not often allow to apply a force on the lever sufficient to release the locking tooth from the rope. Moreover, the locking tooth can be permanently locked in its engaging position for different reasons, for example either because of the presence of ice or debris in the body of the device, or due to excessive deformation of the rope, etc., thereby actually causing the jamming of the device.
- the object of the present invention is to provide a locking and ascent device for climbs which overcomes the drawbacks of the conventional devices while being easy to manufacture and use.
- a locking and ascent device for climbs comprising a body being provided with a seat for housing a rope, a locking element movable between a releasing position with said rope, where said rope slides within said seat, and an engaging position with said rope, where said rope is prevented from sliding within said seat in a direction, suitable means for bringing said locking element back to said engaging position following a movement of the latter and manual operating means for said locking element, characterized in that said manual operating means comprise a feeler cooperating with a surface of said body for moving said locking element to said releasing position.
- the device according to the present invention may be advantageously used both in the sports field and in the professional field. Generally, the device may apply to all the cases where a user has to climb by means of either a rope, a string, a cable or an element equivalent thereto.

Abstract
Description
- The present invention relates to a locking and ascent device for climbs by means of ropes, strings, and the like.
- The use of mechanical devices which can be fastened to ropes, strings, cables, etc., in order to make the climb by a climber easier has been known for a long time. Several conventional devices can be fastened to ropes, strings, etc., such as to freely slide on the latter in a direction, generally the ascent one. When a load is applied in the substantially opposite direction, for example by the climber supporting on these devices, the latter are locked, by integrally coupling with their respective rope or string. These devices are usually known with the name of "rope clamps" .
- The conventional locking and ascent devices generally comprise a body in which there is provided a seat for housing either a rope or an element equivalent thereto (a string, a cable, etc.) and a locking element, typically a tooth. The locking tooth is movable between a releasing position with the rope and an engaging position with the latter. In the first case, when the locking tooth does not engage the rope, the latter can slide within the respective seat. In the second case, the locking tooth engages the rope by clamping the latter and preventing that the latter may slide within its respective seat solely along a predetermined direction, generally the descent one causing the device to move downwards along the vertically extending rope. In fact, when the locking and ascent device is thrust by the user in the allowed direction along the rope, generally the ascent direction, the tooth will release the rope, thus allowing the latter to slide within its seat.
- The conventional devices are usually provided with a handle for the climber and a spring having the function of bringing the locking tooth, following a movement of the same, back in contact with the respective rope. Thereby, the locking tooth is usually rested on the rope housed in the seat. Accordingly, a conventional device may slide on the rope in the direction allowed, with the locking tooth which does not interfere with the rope movement. When a load is applied to the device handle in the direction opposite to the free-sliding direction on the rope, the locking tooth moves towards the rope, thereby the latter is compressed in the respective seat and prevented from moving further.
- The locking tooth is usually fastened to a safety lever to be manually operated by the climber. The safety lever allows the climbing user to intentionally unfasten the locking tooth from the rope, the latter being thereby brought to the releasing position.
- A drawback with the conventional locking and ascent devices is that the safety lever is often difficult to operate by the climber. In fact, this lever is usually operated through the thumb of the hand with which the user manoeuvres the respective locking and ascent device. The movement to be performed by the user is not easy and does not often allow to apply a force on the lever sufficient to release the locking tooth from the rope. Moreover, the locking tooth can be permanently locked in its engaging position for different reasons, for example either because of the presence of ice or debris in the body of the device, or due to excessive deformation of the rope, etc., thereby actually causing the jamming of the device.
- The need for having a locking and ascent device which is easy to be operated by the user, even in difficult conditions of use, has been felt for a long time.
- The object of the present invention is to provide a locking and ascent device for climbs which overcomes the drawbacks of the conventional devices while being easy to manufacture and use.
- This and other objects are achieved by the present invention which relates to a locking and ascent device for climbs comprising a body being provided with a seat for housing a rope, a locking element movable between a releasing position with said rope, where said rope slides within said seat, and an engaging position with said rope, where said rope is prevented from sliding within said seat in a direction, suitable means for bringing said locking element back to said engaging position following a movement of the latter and manual operating means for said locking element, characterized in that said manual operating means comprise a feeler cooperating with a surface of said body for moving said locking element to said releasing position.
- The device according to the present invention may be advantageously used both in the sports field and in the professional field. Generally, the device may apply to all the cases where a user has to climb by means of either a rope, a string, a cable or an element equivalent thereto.
- The presence of the feeler, which is coupled with a surface of the body of the device, for example according to a cam-feeler coupling, allows to sensibly reduce the force that the user has to apply to the manual operating means in order to release the locking element.
- The locking element is rotatably fastened to the body of the device and is provided with an abutment surface suitable to compress a rope within its seat. Preferably, the manual operating means comprise a lever hinged on the locking element, for example a conventional safety lever, and the feeler is coupled with the lever.
- According to the present invention, the feeler engages said surface of the body of the device upon a relative rotation of the lever relative to the locking element.
- In the preferred embodiment of the present invention, the surface intended to cooperate with the feeler belongs to the seat for housing the rope.
- In general, when the feeler, for example a protuberance, a cylinder or an equivalent abutment/sliding element, engages the surface being associated thereto, the lever moves the locking element towards its releasing position, thus requiring a lower effort by the user as compared with conventional devices. Advantageously, the locking element is operated by gradually reducing the pressure applied by the abutment surface on the rope (or string), since the fastening between the feeler and its respective sliding surface allows to enhance the force applied by the user to the lever. In fact, the contact point between the feeler and said surface is preferably a pitch point for the lever operated by the user.
- Further aspects and advantages of the present invention will be better understood from the following description, which is given by way of illustrative and non-limiting example with reference to the annexed schematic drawings, in which:
- Fig. 1 is a side view of a device according to the present invention in a first configuration;
- Fig. 2 is a side view of the device illustrated in Fig. 1 in a second configuration;
- Fig. 3 is a side view of the device illustrated in Fig. 1 in a third configuration;
- Fig. 4 is a top view of the device illustrated in Fig. 2.
- With reference to Figs. 1-4, a
device 1 according to the present invention is shown comprising abody 2 provided with aseat 3 in which either arope 4 or an element equivalent thereto, for example a string, a cable, etc., can be slidingly housed. Therope 4 extends, for example, vertical to a surface which a user has to ascent. - The
device 1 is provided with a handle M for a user's grip. The handle M can be covered with a suitably shaped, anti-slip material. - A
locking element 5 is rotatably fastened to thebody 2, through thehinge 51. Theelement 5 may have different shapes, but in general is provided with anabutment surface 10 intended to compress therope 4 within theseat 3. As illustrated in Fig. 4, thedevice 1 is provided withresilient means 6 having the function of bringing thelocking element 5, following a movement of the latter, back in contact withrope 4. In the embodiment shown, theresilient element 6 is a spring fastened to thehinge 51. - Fig. 2 shows the
device 1 with thelocking element 5 in the releasing position thereof with therope 4. In this position the pressure that theelement 5 exerts on therope 4 through theabutment surface 10 is the least, and is essentially due to the action of thespring 6. Any sliding of therope 4 in the direction of arrow S, this sliding being due for example to a load L applied to thedevice 1, causes thelocking element 5 to move to the engaging position shown in Fig. 1. In fact, any sliding of therope 4 in the direction of arrow S causes a sudden rotation of thelocking element 5 in the direction of arrow C, due to the friction generated between thesurface 10 and therope 4. The friction between therope 4 and theelement 5 increases when theelement 5 is rotated, and the rope is locked within theseat 3. - Fig. 1 shows the
device 1 with thelocking element 5 in the engaging position, where therope 4 is prevented to slide within theseat 3 in the direction S. The load L is for example the weight applied by the climber clinging at the handle M for supporting. - The
device 1 is provided withmeans 7 having the function of allowing the manual operating of thelocking element 5. In the embodiment shown in Figs. 1-4, thedevice 1 is provided with alever 7 being rotatably fastened to thelocking element 5 through thehinge 71. Thelever 7 is movable in aseat 52 provided on the upper surface of thelocking element 5. Therefore, the rotation of thelever 7 relative to theelement 5 is comprised within an angle interval determined by the shape of theseat 52. - In order to facilitate the grip of the
lever 7 by the user, for example through the thumb, thelever 7 is preferably provided with a protuberance 72 (Figs. 2 and 4), for example a cylinder. - After the
locking element 5 is in the engaging position such as shown in Fig. 1, the user can operate thelever 7, for example by applying a force in the direction L on the latter, in order to release theelement 5 from therope 4. Thelever 7 rotates relative to theelement 5 and, through thehinge 71, causes theelement 5 to rotate in the opposite direction of arrow C. Thereby, thelocking element 5 can be brought to its releasing position such as shown in Fig. 2. Advantageously, thedevice 1 is provided with afeeler 8 having the function of facilitating the operation ofelement 5 through thelever 7. - The
feeler 8 cooperates with a surface of thedevice 1 in order to guide thelever 7 when the latter is operated and enhance the force that thelever 7 transmits to thelocking element 5. The coupling between thefeeler 8 and the corresponding surface can be of the cam-feeler type. In general, thefeeler 8 may be a pivot, a cylinder, a wheel, a protuberance or any element suitable to either slide or roll on a sliding surface. In the embodiment shown, thefeeler 8 is a cylinder integral to thelever 7, the surface associated thereto being theend 9 of theseat 3. - As illustrated in Fig. 2, when the
lever 7 is operated by the user in order to release therope 4 and allow the same to slide within theseat 3, thefeeler 8 contacts thesurface 9, thus engaging the latter along a tract. In the embodiment shown, thecylinder 8 slides on thesurface 9. Preferably, the contact point between thecylinder 8 and thesurface 9 is a pitch point for thelever 7. - After the
locking element 5 has been brought to the releasing position as shown in Fig. 2, it can be further rotated in order to completely release theseat 3. Fig. 3 shows thedevice 1 with the lockingelement 5 in the end-of-stroke position, where thelever 7 engages thesurface 11 of thebody 2 and therope 4 can be separated from thedevice 1. - As stated above, the fastening between the feeler 8 (in this particular case, the cylinder), and the
surface 9 enhances the effect oflever 7 on theelement 5. Consequently, a lower operating force is required to the user as compared with the conventional devices which are not provided with the feeler, even in the case where the jamming element of thelocking element 5 on therope 4.
