Abstract
A fall arrest device comprises two clamp portions 5, 7 which are hingedly connected to two connecting arms 9, 11 which are hingedly connected to a coupling element 13 to which a carabiner can be affixed. The fall arrest device further includes a pawl 25 which is present pivotable around the coupling element. The brake operation principle is based on the two clamp portions which in the event of a fall are pushed towards each other as a result of the geometry of the device. In neutral position the distance between the two clamp portions will be smaller than the diameter of the cable. To increase the distance for lodging the cable between the two clamp portions, the coupling element to which the carabiner is affixed is to be lifted. The pawl is primarily intended to act as a lock. This is arranged in such manner so as to prevent the mechanism from clicking open when the user performs an ascending action.
Description
A device for stopping a fall during climbing or descending along a rope
DESCRIPTION:
Field of the invention
The invention relates to a fall arrest device (fall arrester) for stopping a fall during ascending or descending action along a cable, comprising:
- two oblong clamp portions which are spaced apart from each other and which during operation are present on either one of the two sides of the cable and slide over the cable, where each of these clamp portions is provided with a clamp surface, which clamp surfaces are located opposite each other and are facing each other, and where each of the clamp portions has two ends seen in longitudinal direction,
- two connecting arms which are spaced apart from each other, where each clamp portion is hingedly connected to each of the connecting arms, and
a coupling element to which a carabiner can be affixed and which is hingedly connected to one of the ends of each of the connecting arms. Position of the art
A fall arrest device of this type is known from DE3216231A. In this known fall arrest device the connecting arms midway between the clamp portions, seen in longitudinal direction of the clamp portions, are connected to the clamp portions and the connecting arms, seen in longitudinal direction of the clamp portions, are located beside each other and spaced apart from each other. This fall arrest device comprises a plurality of parts that, in the event of a fall, move relative to each other so as to block the fall arrest device against a downward move along a cable. If these parts are incapable of moving/rotating in a flexible manner, the operation will be adversely affected as a result.
Summary of the invention
It is an object of the invention to provide a fall arrest device of the type defined in the opening paragraph which is simple, robust and reliable. For this purpose the fall arrest device according to the invention is characterized in that:
the connecting arms are present spaced apart from each other seen in longitudinal direction of the clamp portions, and
one of the ends of each clamp portion is hingedly connected to one of the connecting arms while the other end is connected to the other connecting arm.
Preferably, the clamp portions run parallel to each other and the clamp surfaces are oblong and also run parallel to each other.
An embodiment of the fall arrest device according to the invention is characterized in that the hinge points of the clamp portions with one of the connecting arms, seen in longitudinal direction of the cable situated between the clamp portions during operation, are spaced apart from each other, where the lower of the two hinge points is located between the two ends of the connecting arm and the first connecting arm end connected to the coupling element is located on the same side of the cable as this lower hinge point, so that, in the event of a downward movement of the coupling element relative to clamp portions, the clamp surfaces are moved towards each other, and in the event of an upward movement of the coupling element relative to clamp portions, the clamp surfaces are moved away from each other.
A further embodiment of the fall arrest device according to the invention is characterized in that the fall arrest device further includes a pawl which is located on the coupling element and can rotate around a pivot shaft and is connected to the coupling element between said first ends of the connecting arms. The purpose of this pawl is to prevent the clamp portions from moving away from each other and ending in the release position when the user ascends, in which release position the fall arrest device can be disengaged from the cable. When the user wishes to disengage the fall arrest device from the cable he/she is to push the pawl away. This pawl has a free end which can be moved between:
an up/down position in which the clamp portions slightly press against the cable and the fall arrest device cannot be disengaged from the cable, and in which the pawl prevents an up movement of the coupling element relative to the clamp portions when the fall arrest device is situated on a cable,
a clamp position in which the clamp portions firmly press against the cable, and
a release position in which the pawl allows of an upward movement of the coupling element relative to the clamp portions in the event of the presence of the fall arrest device on a cable, so that the fall arrest device can be disengaged from the cable.
Preferably, the fall arrest device comprises a spring that pushes the pawl to the clamp position. This spring provides that the pawl retracts to the original position (clamp position) when it is released. The spring additionally provides that in the clamp position the cable is (slightly) squeezed as a result of which the user, in the event of a fall, draws up the fall arrest device and the braking mechanism can start operating.
Yet a further embodiment of the fall arrest device according to the invention is characterized in that the pawl is provided with a pin that can be moved in a curved groove provided in the coupling element when the pawl is rotated between the clamp position and release position, and in that the coupling element comprises a blocking element which, when the fall arrest device is engaged with a cable upside down, fits in the groove under the influence of gravity and prevents the pin from moving through the groove and thus blocks the pawl. This pin is to provide that the clamp portions cannot change to the release position when the fall arrest device is placed on the cable in an upside down position. Gravity as well as the freedom of movement of this pin provide that the pawl in this position is blocked against rotation and as a result the clamp portions cannot be moved away from each other.

Detailed description of the drawings
Figs. 1, 2A and 3 show various views of an invented embodiment of the fall arrest device (fall arrester) for stopping a fall during ascending or descending action along a cable when the device is in engagement with a cable. The fall arrest device 1 comprises two oblong clamp portions 5 and 7 which run parallel to each other and are spaced apart from each other and which during use are located on either one of the two sides of the cable 3 and slide over the cable. Each of these clamp portions has an elongated clamp surface 6 and 8 which also run parallel to each other. These clamp surfaces are situated opposite each other and are facing each other. The fall arrest device 1 further includes two connecting arms 9 and 11 spaced apart from each other connecting the clamp portions 5 and 7 to each other and to a coupling element 13. Each clamp portion 5 and 7 with an end 5a and 7a is hingedly connected to the connecting arm 9 and with the other end 5b, 7b to the other connecting arm 11, while the coupling element 13 is hingedly connected to an end 9a, 11a of each of the connecting arms. A carabiner 15 may be affixed to the coupling element 13.
The two hinge points 17 and 19, 21 and 23 respectively of each of the clamp portions 5 and 7 with one of the connecting arms 9 and 11 are located at a distance 20 from each other seen in longitudinal direction of the cable 3. The lower one of the two hinge points 19 and 23 respectively is located between the two ends 9a and 9b and 11a and l ib respectively of the connecting arm 9 and 11 and the first coupling-element-connected end 9a, 11a respectively of the connecting arm is located on the same side of the cable 3 as the lower hinge point 19, 23 respectively. In the event of a downward movement of the coupling element 13 relative to the clamp portions 5 and 7, the clamp surfaces 6 and 8 will move towards each other as a result of this geometry and in the event of an upward movement of the coupling element 13 relative to clamp portions 5 and 7 the clamp surfaces 6 and 8 will move away from each other.
The clamp surfaces 6 and 8 are smooth curved planes. For increasing the grip on the cable 3 these clamp surfaces may also be arranged as straight planes. This is represented in Fig. 2B in which the clamp surfaces 6' and 8' of an alternative fall arrest device Γ are arranged as having a V-shaped cross section. The clamp surfaces may also be roughened or provided with teeth for increasing the grip on the cable.
The fall arrest device further includes a pawl 25 which can be pivoted around a pivot shaft 27 which is located between the first ends 9a and 11a of the connecting arms 9 and 11 on the coupling element 13. The purpose of this pawl is to avoid that during the ascending operation the clamp portions can move away from each other and end up in the release position in which the fall arrest device may be disengaged from the cable. When the user wishes to disengage the fall arrest device from the cable he/she is to push the pawl away. A torsion spring 29 provides that the pawl 25 is retracted to the original position when it is let go of. In addition, the torsion spring provides that when in the clamp position the cable is (slightly) clamped, so that the user, in the event of a fall, takes in the fall arrest device, and the braking principle is rendered operative.
For a further clarification of the operation of the fall arrest device as well as the pawl, Figs. 4, 5 and 6 show the fall arrest device in clamp position, move position and release position respectively. In the move position A (Fig. 4) the clamp portions 5 and 7 are slightly pressed against the cable 3 in that the pawl 25, due to the presence of the torsion spring 29, presses with a free end 25a against the clamp portion 7. In this position the pawl 25 imparts an upward movement of the coupling element 13 relative to the clamp portions 5 and 7, so that the fall arrest device 1 cannot be disengaged from the cable 3. For pressing the clamp portions more firmly against the cable an additional torsion spring 30 (see Fig. 4) may be installed, for example around hinge point 19 (or for example around hinge point 23) which torsion spring with one end rests against clamp portion 7 and with the other end against connecting arm 9. In the clamp position B (Fig. 5) the clamp portions 5 and 7 firmly press against the cable 3. This position is occupied in the event of a fall of the user who is connected to the coupling element 13 by means of a carabiner. As a result of the fall the coupling element 13 is pulled downward and the two clamp portions are pushed towards each other. In the release position C (Fig. 6) the pawl 25 allows of an upward movement of the coupling element 13 relative to the clamp portions 5 and 7, so that the fall arrest device can be disengaged from the cable. This release position cannot be occupied until the pawl 25 is manually pulled into the position represented in Fig. 6 against the spring force.
To the pawl 25 is affixed a pin 31 hat provides that the clamp portions cannot click to the release position if the fall arrest device is placed upside down on the cable. This is illustrated while reference is made to Figs. 7 and 9 in which the fall arrest device is represented upside down in the release state and move state respectively. Figs. 8 and 10 give detailed representations of this at the location of this pin 31. During the rotation of the pawl 25 between the clamp state B and the release state C the pin 31 can be moved in a curved
groove 33 which is present in the coupling element 13. In the middle of the side wall of the curved groove 33 there is a recess 34 which accommodates a blocking element 35. If the fall arrest device is placed upside down on a cable, the blocking element 35 will drop from the recess 34 into the groove 33 owing to gravity and thus block the moving of the pin 31 through the groove and thus a rotation of the pawl 25. As a result, the coupling element 13 cannot be moved relative to the two clamp portions 5 and 7 so that, in consequence, the clamp portions can neither be moved towards each other nor away from each other.
Although the invention has been described in the foregoing based on the drawings, it should be observed that the invention is not by any manner or means restricted to the embodiment shown in the drawings. The invention also extends to all embodiments deviating from the embodiment shown in the drawings within the scope defined by the claims.
