DETAILED DESCRIPTION OF ILLUSTRATED EMBODIMENTS

[0061] Same or similar components in the figures are provided with the same reference signs. The representations in the figures are schematic and not drawn to scale.

[0062] FIG. 1 to FIG. 4 show schematic representations of a first variant of an inventive securing device 100. In FIG. 1, the securing device 100 is shown in the release position, in FIG. 2, the securing device 100 is shown in the securing position, and in FIG. 3, the securing device 100 is shown in a further securing position.

[0063] The securing device 100 is attachable to a person to be secured and is configured for moving along with a person to be secured along an elongated securing means 150. A receiving housing 110 comprises a receiving groove 112 and two sidewalls which are spaced apart and opposite each other, which extend from the receiving groove 112, such that the receiving groove 112 and the sidewalls partially surround the securing means 150. A securing lever 101 with an attachment region 102 is provided to which the person is attachable, wherein the securing lever 101 is pivotably mounted between the sidewalls. The securing lever 101 is configured and pivotable such that, in a securing position in which the securing means is blocked within the receiving groove 112 against a displacement in at least one direction along the securing means 150, the securing means is pushable into the receiving groove 112 and the attachment region 102 protrudes out of the receiving housing 110 for being operated, and, in a release position in which the securing means is displaceable within the receiving groove 112, the securing lever 101 is present in the receiving housing 110 in a covered manner between the sidewalls, such that attaching the person to the attachment region 102 is prevented.

[0064] The receiving housing 110 comprises a longitudinal extension along the securing means (securing rope) 150 and encloses with the receiving groove 112 and the both opposing sidewalls the inserted securing means 150. In other words, into the receiving groove 112, the securing means 150 is insertable. From the receiving groove 112, the both sidewalls extend which are spaced apart and in particular in parallel with respect to each other. The receiving housing 110 correspondingly forms a U-shaped profile in cross-section. The receiving housing 110 is illustrated in a perspective illustration in FIG. 4.

[0065] Between the both opposing sidewalls 111, 400, an installation space is formed in which the securing means 150 is insertable and in which the securing lever 101 is pivotably mounted. For example, the securing lever 101 may be pivotably attached by means of a fulcrum pin and fulcrum bolt, respectively, which is fixed to at least one of the sidewalls 111, 400 and protrudes in the installation space.

[0066] The securing lever 101 is formed with an attachment region 102 to which the person can attach himself for example by means of a safety harness. The attachment region 102 may comprise an opening, for example, in which a carabiner of a person-securing rope is attached.

[0067] The securing lever 101 is further configured and pivotably arranged, such that it may pivot between a securing position (FIG. 2) and a release position (FIG. 1). In the securing position, the securing lever 101 and the securing cam 120, respectively, pushes and clamps, respectively, the securing means 150 in the receiving groove 112, such that the securing device 100 cannot be displaced in a blocking direction 152 along the securing means 150 anymore. In a direction opposite to the blocking direction 152, for example along an ascent direction 151 along the securing means 150, the securing device 100 may nevertheless be configured displaceable. For example, this may be provided by a friction surface 125 and braking surface, respectively, of the securing cam 120 which is pushed against the securing means 150 in the securing position. The friction surface 125 comprises teeth, for example, which protrude with their tips in the direction of the blocking direction 152. Thus, the tips do not hook during a motion of the securing device 100 in the ascent direction 151 and against the blocking direction 152, while the tips are wedging in the securing means 150 during a motion of the securing device 100 in the blocking direction 152. By a specific biasing of the securing lever 101 and/or the securing cam 120, a braking force can be adjusted in a targeted manner which acts upon the securing means 150 in the securing position.

[0068] At the same time, the securing lever 101 in the securing position is in a position in which the attachment region 102 is accessible and is operable by the person and for example a securing carabiner, respectively (see FIG. 2). In other words, in the securing position, the attachment region 102 protrudes out of the installation space between the both sidewalls 111, 400, such that the sidewalls 111, 400 do not cover the attachment region 102. This results in that, in the securing position wherein the attachment region 102 can be reached by the user, displacing and in the worst case falling of the securing device 100 along the securing means 150 is prevented.

[0069] On the contrary, in the release position, the securing lever 101 is pivoted such that its attachment region 102 is present between the both sidewalls 111, 400 in the installation space, such that the sidewalls 111, 400 cover the attachment region 102. The user and the person, respectively, correspondingly cannot reach the attachment region 102 and correspondingly cannot attach a carabiner to the attachment region 102, for example. At the same time, the securing lever 101 releases the securing means 150 and does not push the securing means 150 against the securing cam 120 in a blocking manner, respectively. Thus, the securing device 100 can be freely displaced again and can displaced for example to a desired location along the securing means 150 without a person being secured at the securing device 100.

[0070] In this way, it is achieved that the securing device 100 is present in the securing position as soon as a person is coupled to the attachment region 102 of the securing lever 101. A displacement of the securing device 100 along the securing means 150 in a defined blocking direction 152 is thus not possible.

[0071] In contrast to this, the securing device 100 is present in the release position when no securing element of the person to be secured is coupled to the attachment region 102 and the attachment region 102 is correspondingly retracted in the installation space and is covered by the sidewalls. The security associated with this, that no person is coupled to the securing device 100 results in that the securing device 100 in the release position is freely displaceable along the securing means 150 and thus can be displaced to a desired target position along the securing means 150 without a person being secured at it.

[0072] The securing lever 101 is attached to at least one of the sidewalls 111, 400 in a manner rotatable around a first rotation axis 103. For example, the securing lever 101 comprises a first end. By rotating the securing lever 101, the first end and the coupling surface 115, respectively, is pivoted in the direction of the receiving body and the receiving groove 112, respectively, until a deadlock between the securing cam 120 and the receiving groove 112 occurs. At the same time, a region of the securing lever 101 which is formed relatively to the first rotation axis 103 with respect to the first end, is further distanced to the securing means 150 and is moved out of the installation space between the both sidewalls 111, 400. In this region, the attachment region 102 is located. Thus, the securing position can be adjusted, wherein a blocking of the securing device 100 along at least one direction along the securing means 150 is realized and at the same time is safely operable.

[0073] This deadlock in the securing position leads to a high friction between the securing means 150, the securing cam 120, and the receiving groove 112, such that a relative motion of the securing device 100 along the securing means 150 is limited in at least one direction. When the force which is acting upon the securing means 150 is increased, the deadlock is reinforced, such that a relative motion between the securing device 100 and the securing means 150 is prevented in all directions. This state is described by the further securing position which is illustrated in FIG. 3.

[0074] The securing lever 101 may be actuated by the person to be secured, for example. For securing, the person may pivot the securing lever 101 from the release position to the securing position and may secure himself to the attachment region 102 of the securing lever 101. During this securing, the securing device 100 cannot be displaced in the blocking direction 152 along the securing means 150. When the person would like to release himself and is already in a secured position, the person may pivot the securing lever 101 to the release position, wherein the securing device 100 is displaceable along the securing means 150, and due to the presence of the attachment region 102 in the installation space, it is ensured that no person is unintentionally secured to the securing device 100, since the attachment region 102 is not accessible and no securing to it is possible.

[0075] The securing cam 120 and the securing lever 101 are arranged such that in the securing position, the securing lever 101 is decoupled from the securing cam 120 (FIG. 2) and the securing cam 120 moves in the direction of the securing means 150, and in the release position, the securing lever 101 is coupled with the securing cam 120, such that the securing lever 101 pushes away the securing cam 120 from the securing means 150 (FIG. 1).

[0076] The securing cam 120 comprises the friction surface 125 which, in the securing position, is pushed and pressed, respectively, against the securing means 150 in the direction of the receiving groove 112, in order to block a displacement of the securing device 100 in at least one direction along the securing means 150. The securing cam 120 may be biased, for example due to its center of gravity, relatively to its rotation axis 121 or by means of a first spring 122, such that without acting upon and coupling, respectively, with the securing lever 101, the securing cam 120 is pivoted in the securing position and pushes the securing means 150 into the receiving groove 112.

[0077] The securing cam 120 is mounted to at least one of the sidewalls 111, 400 in a manner rotatable around a second rotation axis 121 and is present in the installation space between the both sidewalls. For example, the securing cam 120 comprises the friction surface (braking surface) 125. By rotating the securing cam 120, the friction surface 125 is pivoted in the direction of the receiving body and the receiving groove 112, respectively, until a deadlock between the securing cam 120 and the receiving groove 112 is established.

[0078] The second rotation axis 121 of the securing cam 120 is formed between the first rotation axis 103 and the receiving groove 112. Furthermore, the securing lever 101 comprises a coupling surface 115 which is configured such that, in the release position, the coupling surface 115 is coupled with the securing cam 120, such that the securing cam 120 is pivotable away from the receiving groove 112. In other words, the coupling surface 115 of the securing lever 101, in the release position, pushes the friction surface 125 of the securing cam 120 away from the receiving groove 112.

[0079] In the securing position of the securing lever 101, the coupling surface 115 is decoupled from the securing cam 120, such that the securing cam 120, due to its biasing or its gravitational force G, may pivot with its friction surface 125 in the direction of the receiving groove 112. In other words, in the securing position, the friction surface 125 of the securing cam 120 is pushed in the direction of the receiving groove 112.

[0080] The securing cam 120 is formed such that a center of gravity S of the securing cam 120 is formed spaced apart with respect to a (second) rotation axis 121 of the securing cam 120, such that the securing cam 120, due to its gravitational force G, pivots in the securing position and the securing cam 120 pushes the securing means 150 into the receiving groove 112.

[0081] The center of gravity S of the securing cam 120 may in particular be selected such that it is formed between the first and the second rotation axis 121. In particular, the center of gravity S of the securing cam 120 may be specifically adjusted by specifically introducing recesses 124 in the material of the securing cam 120. Thus, the securing cam 120, based on the gravitational force, may pivot in the securing position in the direction of the receiving groove 112. The friction surface 125 of the securing cam 120 may therefore be in contact with the securing means 150. Due to the friction, during a motion of the securing device 100 in the blocking direction 152, the securing cam 120 may be pivoted further in the direction of the receiving groove 112, such that the pressing force against the securing means 150 is increased and the braking effect and blocking effect, respectively, is increased. In contrast to this, during a displacement of the securing device 100 against the gravitational force, for example in the direction of the ascent direction 151, the securing cam 120 may be pivoted away, such that the friction effect and blocking effect, respectively, is reduced.

[0082] The securing cam 120 is biased by means of a first spring 122 in the direction of the securing position, such that the securing cam 120 pivots in the securing position and fixes the securing means 150 in the receiving groove 112. The first spring 122 may be a tension spring or a compression spring, for example, which biases the securing cam 120 in a desired pivoting direction. Furthermore, a torsion spring and clock spring, respectively, may be utilized which biases the securing cam 120 in a desired rotation direction and biasing direction 123, respectively, for example.

[0083] The securing lever 101 is biased by means of a second spring 104 in the direction of the release position, such that, in the release position, the securing cam 120 pivots and the securing cam 120 releases the securing means 150 in the receiving groove 112. For example, this may be achieved by, without a person being secured at the attachment region 102, selecting the spring force of the second spring 104, such that the securing lever 101 in a self-acting manner is pivoted in the direction of the release position, such that the attachment region 102 of the securing lever 101 is located in the installation space between the sidewalls 111, 400. In the embodiment, the biasing direction 123 of the securing cam 120 acts against the biasing direction 105 of the securing lever 101.

[0084] The securing device 100 comprises a rope brake 106 which comprises a braking element 107 which is biasable in the direction of the receiving groove 112. The braking element 107 is a brake block which presses the securing means 150 into the receiving groove 112 with a defined pressure. In the release position in which the securing lever 101 or the securing cam 120 does not exert a braking force on the securing means 150, by means of the rope brake 106, such a slight braking effect can be transferred to the securing means 150, that no uncontrolled accelerating of the securing device 100, in particular along the gravitational force direction, occurs. Thus, a controlled displacing of the securing device 100 along the securing means 150 can be provided in the release position.

[0085] In FIG. 3, a further securing position is shown, in which the securing means 150 within the receiving groove 112 is blocked against a displacing in both directions 151, 152. The securing lever 101 presses the securing cam 120 against the securing means 150 in the receiving groove 112, such that securing means 150 is securely clamped. The attachment region 102 protrudes out of the receiving housing 110 for being operated. The further securing position is an emergency position, for example, in which a displacing of the securing device 100 in both directions along the securing means 150 is prevented. In the further securing position, a further region and coupling surface 301, respectively, of the securing lever 101 pushes on the securing cam 120.

[0086] For example, the attachment region 102 comprises an opening which is selectively closable by means of a carabiner 113. Furthermore, the attachment region 102 may comprise a further opening which is configured as an elongated hole 109. The elongated hole 109 is configured such that, in the securing position, the elongated hole 109 runs with its longitudinal extension I along and outside an outer edge 114 of the first sidewall 111 and/or the second sidewall 400 and thus protrudes out of the receiving housing 110 for being operated. Thus, a securing element can be displaced and adjusted along the entire longitudinal extension I, when the securing lever is located in the securing position.

[0087] Furthermore, the securing device 101 comprises an activation system 116 which is arranged at the securing lever 101, such that the activation system 116 is only operable when the securing lever 101 is present in the securing position. In other words, only in the securing position in which the attachment region 102 is accessible for the user, the activation system 116 can be operated and correspondingly adjust the securing device 100 in an active or an inactive state.

[0088] In the above described embodiment in which the attachment region 102 is configured as elongated hole 109, for example a carabiner of a connecting means can be attached for securing a person. The connecting means (so-called SSB-securing system) possesses two separate carabiners, for example, which communicate with each other, such that respectively only one carabiner can be opened at the same time. Furthermore, a corresponding carabiner may be equipped with a locking system which can only be opened when the other carabiner is present in a secured position.

[0089] Referring to the above described embodiment in which the securing device 100 comprises the activation system 116, it is possible that, when the securing lever 101 is present in the securing position, a corresponding carabiner of the connecting means may be displaced along the elongated hole 109, such that a coupling element of the carabiner may activate or deactivate the activation system 116, as the coupling element may be coupled with the activation system 116 by displacing the carabiner in the elongated hole 109. Correspondingly displacing the carabiner within the elongated hole 109 is only possible when the securing lever 101 is located in the securing position.

[0090] In a further exemplary embodiment, the activation system 116 serves for, when a carabiner of an above described connecting means is coupled to the activation system 116, either the carabiner may be opened or another carabiner which communicates with the coupled carabiner may be opened.

[0091] FIG. 5 to FIG. 7 show schematic illustrations of a second variant of an inventive securing device 100. In FIG. 5, the securing device 100 is shown in the release position, in FIG. 6, the securing device 100 is shown in the securing position, and in FIG. 7, the securing device 100 is shown in a further securing position.

[0092] In contrast to the first variant of the securing device 100, the securing lever 101 is configured with a carabiner 113 in the attachment region 102. In particular, the second variant of the securing device 100 may be configured more compact than the securing device 100 of FIG. 1 to FIG. 4.

[0093] FIG. 8 and FIG. 9 show schematic illustrations of a third variant of an inventive securing device 100. In FIG. 8, the securing device 100 is shown in the release position, and in FIG. 9, the securing device 100 is shown in the securing position.

[0094] The securing lever 101 comprises an elongated hole 109 as attachment region 102. The attachment lever 101 comprises a first biasing direction 105 which is acting against the biasing direction 123 of the securing cam 120. In FIG. 8, it is illustrated that the securing lever 101 pivots with the coupling surface 115 the securing cam 120 against its biasing direction 123, such that the braking surface 125 of the securing cam does not block the securing means 150. In FIG. 9, the securing lever 101 is present in the release position, wherein the securing lever 101 is decoupled from the securing cam 120. The securing cam 120 pivots in biasing direction 123 in the direction of the securing means 150, such that a displacement of the securing device in the direction of the blocking direction 152 is blocked. A stopper 802 may prevent a further displacing of the securing lever 101.

[0095] The securing device 100 comprises a blocking element 801 with an activation system 116, wherein the blocking element 801 is pivotably mounted between the sidewalls 111, 400. The blocking element 801 is configured for pushing the securing means 150 into the receiving groove 112 in a blocking position, and for displaceably mounting the securing means 150 within the receiving groove 112 in a further release position, wherein the activation system 116 selectively adjusts the blocking element 801 in the blocking position and the release position. The blocking element is configured as pivotable braking lever. The blocking element 801 may activate and deactivate the securing device 100. In an active state, the above described operation of the securing lever 101 may result in that the securing device 100 is displaceable in the release position. In an inactive state of the securing device 100, the blocking element 801 blocks each displacement of the securing device 100 independently from the securing lever 101 being present in the securing position or the release position.

[0096] FIG. 10 shows a schematic illustration of a securing system according to an exemplary embodiment of the present invention. The securing system is attachable to a person to be secured and is configured for moving along an elongated securing means 150. The securing system comprises a first securing device 1001 and a second securing device 1002 to which a person is fixable. Furthermore, the securing system comprises a spacer 1003 which is spacing the first securing device 1001 and the second securing device 1002 with respect to each other, in particular along the securing means 150. For example, the first securing device 1001 is configured correspondingly to the embodiment of FIGS. 8 and 9, and the second securing device 1002 is configured correspondingly to the embodiment of FIG. 5 to FIG. 7, for example. Thus, the person may couple himself with multiple securing components to the securing devices 1001, 1002. In particular, the person may attach himself with an abdominal belt, for example to the second securing device 1002. For example, the person may hook in the first securing device 1001 which is spaced above in the ascent direction 151, for example by a carabiner of a connecting means (so-called SSB-securing system). A hooking-in of the carabiner of the connecting means results in that a communicating further carabiner of the connecting means can be opened, for example.
