DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

(8) Same or similar components in different figures are provided with the same reference numerals. The representations in the figures are schematically.

(9) FIG. 1 to FIG. 3D show exemplary embodiments of the securing device 100 for securing a person, according to the invention. In FIG. 1, a lever 105 is represented in a releasing position, and in FIG. 2A and FIG. 2B, the lever 105 is represented in a blocking position.

(10) The securing device 100 has a support structure (or carrier structure) 101 (e.g. a supporting housing) and a rope drum (or cable drum) 102. A safety rope 103 (and/or a safety ribbon), to which the person is attachable, is reelable on (and correspondingly unreelable from) the rope drum 102. The securing device 100 further has an axle element 104, which is attached torque-proofly to the rope drum 102 and rotatably to the support structure 101 (for example by a friction bearing or a ball bearing), such that the rope drum 102 is supported rotatably at the support structure 101 by the axle element 104.

(11) The securing device 100 further has a lever 105, wherein the lever 105 is pivotably attached to the support structure 101 at an attachment point 106. The lever 105 has a blocking section 107. In a blocking position of the lever 105 (see FIG. 2), the lever is coupled to the rope drum in order to disable a rotation of the rope drum 102 (and accordingly an unreeling of the safety rope 103). In a releasing position of the lever 105 (see FIG. 1), the blocking section 107 is decoupled from the rope drum 102 and the rope drum 102 is rotatable (and accordingly, an unreeling of the safety rope 103 is enabled).

(12) The lever 105 has a thread section 108, which is arranged spaced apart from the blocking section 107. The axle element 104 has a further thread section 109. The thread section 108 is coupled to the further thread section 109 by means of a thread connection, such that, upon rotation of the axle element 104, due to the rotation of the rope drum 102, the thread section 108 is shifted along the axle element 104 (so to say in an axis direction 117 of the rope drum 102 and the axle element 104), such that, due to the shifting of the thread section 108, a rotation of the lever 105 around the deflection point 106 and an adjustment between the blocking position and the releasing position of the lever 105 are effected.

(13) In the shown embodiment, the support structure 101 forms a housing, which houses the rope drum 102 and the further elements of the securing device, such as for example the lever 105 and the axle element 104. For example, a securing element 501 (see FIG. 5) can be arranged at the support structure 101, by means of which securing element the support structure 101 and thus the securing device 100 can be attached to a load-bearing structure, such as for example a wall or a pillar, or to the person to be secured.

(14) The rope drum 102 has a reeling section and/or a reeling path 123, on which the safety rope 103 is reeled. The safety rope 103 is attached to the rope drum 102 with one end, and is reeled on the rope drum 102 due to a rotation of the rope drum 102. Alternatively, and as is represented further below in FIG. 6, the safety rope 103 can be guided through the rope drum 102. The safety rope 103 can be unreeled from the rope drum 102 as long as the rope drum 102 is rotatable at the support structure 101. The rope drum 102 is rotatable as long as the lever 105 is present in the releasing position (see FIG. 1). The safety rope 103 may, at another end, further be attached to the person to be secured or to a load-bearing structure and/or an attachment point, such as for example a wall or a pillar.

(15) As from a particular unreeled rope length of the safety rope 103, the lever 105 adjusts in the blocking position (see FIG. 2A and FIG. 2B), and blocks a further rotation of the rope drum 102 and thus a further unreeling of the safety rope 103 from the rope drum 102.

(16) The axle element 104 is coupled torque-proofly to the rope drum 102, and is attached to the support structure 101 rotatably relatively to the support structure 101. The rope drum 102 and the axle element 104 rotate relative to the support structure 101 around the rotation axis 117.

(17) The lever 105 is attached rotatably to the support structure 101 at the deflection point 106. For example, the rotation pin 106 may form the deflection point 106, by which the lever 105 is attached pivotably to the support structure 101.

(18) In the exemplary embodiment, the lever 105 is formed as an angle lever. Along the lever 105, the lever has the blocking section 107 and, spaced apart therefrom, the thread section 108. The lever 105 has a first leg 111 and a second leg 112, which is bent from the first leg 111. The blocking section 107 is formed at the first leg 111, and the thread section 108 is formed at the second leg 112. In the angle lever 105, both opposite ends are not located along one extension direction, which extends in a longitudinal direction through the lever 105. The first leg 111 having the first end of the lever 105 has for example a first extension direction, and the second leg 112 having the second end of the lever 105, which second end is opposite to the first end, has a second extension direction, wherein an angle is present between the first extension direction and the second extension direction. The angle of the present angle lever 105 between the first leg 111 and the second leg 112 amounts to for example 45 degrees.

(19) In the embodiment example shown, the second leg 112 extends from the axle element 104 besides the rope drum 102 radially outwardly up to the deflection point 106. The first leg 111 extends from the deflection point 106 along an axial direction with respect to the rotation axis 117. The deflection point 106 is located between the thread section 108 and the blocking section 107.

(20) Thus, the blocking section 107 and the thread section 108 are spaced apart radially from each other and, simultaneously, are spaced apart axially from each other. The angle lever 105 is formed such that by rotating the lever 105 around the deflection point 106, a radial distance between the blocking section 107 and the rope drum 102 is changed.

(21) The blocking section 107 is formed to prevent, in the blocking position of the lever 105, the rotation of the rope drum 102 and, accordingly, the unreeling of the safety rope 103.

(22) The rope drum 102 has at least one snap notch 301 (see FIG. 3), wherein the lever 105, in the blocking position, forms a form-fit with the snap notch 301 of the rope drum. The securing device 100 has a snap cam 121, which is arranged pivotably around a rotation axis 118 (which extends e.g. parallel to the rotation axis 117) to the support structure 101. In the blocking position, the blocking section 107 of the lever 105 swivels the snap cam 121 until the latter engages in the snap notch 301 for forming the form-fit (see FIG. 4). Thus, the lever 105 forms the form-fit indirectly via the snap cam 121.

(23) The pivotable snap cam 121 may for example have a return spring, the spring force of which pushes and/or pulls the snap cam 121 out of the snap notch 301. Thus, the snap cam 121 swivels out of the snap notch automatically, if the lever 105 is arranged in the releasing position and the blocking section 107 thereof (of the lever) does not press on the snap cam 121.

(24) The thread section 108 of the lever 105 corresponds to the further thread section 109 of the axle element 104, such that a thread connection is established between the lever 105 and the axle element 104. Upon rotation of the axle element 104, which is caused by the rotation of the rope drum 102 and correspondingly by the unreeling of the safety rope 103, the thread section migrates along the further thread section of the axle element 104 (that is in particular along the rotation axis 117 of the axle element 104), such that the movement of the thread section 108 along the axle element 104 causes an adjustment and/or a swiveling of the lever 105 around the deflection point 106.

(25) If the rope drum 102 and/or the axle element 104 rotates in a first rotation direction (in FIG. 1 and FIG. 2A along the rotation axis 117, from the left to the right) in order to unreel the rope 103, the lever 105 swivels from the releasing position in the blocking position, until the lever 105 disables the rotation of the rope drum 102 and the blocking position is reached (see FIG. 2).

(26) If the safety rope 103 is reeled again on the rope drum 102, then the rope drum 102 and/or the axle element 104 rotates in a second rotation direction (in FIG. 1 and FIG. 2A along the rotation axis 117, from the right to the left), which is opposite to the first rotation direction. Upon rotation of the rope drum 102 in the second rotation direction, the lever 105 swivels from the blocking position in the releasing position (see FIG. 1).

(27) The present securing device 100 may thus prescribe an unreeling length of the safety rope 103. As from a desired unreeled rope length, which is indicative with a number of rotations of the rope drum 102, the lever 105 is in the blocking position due to the thread coupling, such that a further unreeling is blocked as from the desired unreeled rope length. Thus, a desired roping area for the person to be secured can be adjusted, though at the same time the safety rope 103 is reeled on the rope drum 102 and does not, in a loose state, hamper the movement of the person to be secured, if the prescribed roping length is not reached yet.

(28) In summary, the lever 105 is connected to the rope drum via a thread. By the pulling out of the ribbon (safety rope 103), the rope drum 102 is set in motion. The rope drum 102 in turn shifts the lever 105 horizontally (i.e. along the rotation axis 117 in FIG. 1) on the drum axis, i.e. the axle element 104, due to the thread connection. The horizontal movement is deflected in a vertical movement (which is perpendicular to the rotation axis 117) via the deflection point 106, and is thus deviated to the snap cam 121.

(29) FIG. 2A and FIG. 2B show an end position, in which the ribbon and/or the safety rope 103 is pulled out up to a desired rope/ribbon length. By the pulling out of the rope and the corresponding rotation of the rope drum 102, the lever 105 has been brought to the outermost position (the position at the right hand side in FIG. 2A) of the drum axis, i.e. the axle element 104, via the thread connection. The movement of the lever, which is horizontal in FIG. 2A, has been deflected, via the deflection point 106, in a movement 201 (which is perpendicular to the rotation axis 117), which is vertical in FIG. 2A, and thus has been deviated to the snap cam 121.

(30) The movement path of the lever 105, and thus the stroke path of the snap cam 121, are adjusted precisely and are in relation to different components, among others the length of the ribbon 103, the drum diameter of the rope drum 102, as well as the inclinations and lengths of the thread of the thread section 108 and of the further thread section 109.

(31) Via an adjustment button as an actuation means 110, this relation can be changed by shifting the deflection point 106. Thus, after a readjustment of the lever 105, the latter abuts on the snap cam 121 earlier or later, dependent on the rotations of the rope drum, whereby the rope drum 102 is blocked earlier.

(32) The further the adjustment button 110 and thus the deflection point 106 is shifted away from the neutral position, i.e. away from the rope drum 102, the shorter is the path for the lever 105/the snap cam 121 for blocking the rope drum 102. In result of this, also the possible unreeling length of the ribbon 103 is decreased.

(33) The unloaded ribbon (or safety rope) 103 is reeled via the rope drum 102 and e.g. the spiral coil that is incorporated therein. The snap cam 121 is mounted such that the reeling is enabled at any time, independent of the position of the adjustment button 110.

(34) In the following, the coupling of the thread section 108 with the further thread section 109 according to the shown embodiment example is explained.

(35) The thread section 108 has a lever section 113 and a thread element 114.

(36) The thread element 114 of the lever 105 is a threaded nut, which has an interior thread. The further thread section 109 of the axle element 104 has a corresponding outer thread, such that the threaded nut is movable along the outer thread, if the axle element 104 rotates.

(37) The thread element 114 is pivotably attached to the lever section 113, for example by an attachment pin 116. Beside the pivotable arrangement, the thread element 114 is also attached (translationally) shiftable to the lever section 113. Accordingly, the lever section 113 has an elongated hole 115, in which the attachment pin 116 is supported (translationally) shiftable. The formation of the elongated hole 115 is adapted to the swiveling path of the lever 105 and/or of the lever section 113 and the attachment pin 116 upon the rotation of the lever 105 around the deflection point 106.

(38) Thus, the thread element 114 may shift translationally along the further thread section 109 of the axle element 104 (that is, along the rotation axis 117 and/or the shifting direction 201), and the lever 105 may rotate around the deflection point 106, without a mechanical wedging and/or a blocking of the movement mechanics being effected.

(39) In the present embodiment example, the deflection point 106 is formed via a rotation pin 106. The rotation pin 106 is adjustable relative to the support structure 101, in particular parallel along an axis direction 117 of the axle element 104.

(40) A shifting of the rotation pin 106 and accordingly of the deflection point 106 causes a change of the distance between the lever 105 and the rope drum 102. Upon a change of the distance between the lever 105 and the rope drum 102, and in particular upon a change of the deflection point 106 of the lever 105 relative to the rope drum 102, also the entry (or start) of the blocking position of the lever 105 with respect to a movement of the thread section 108 of the lever 105 along the axle element 104 changes. By a change of the deflection point 106 of the lever 105, also the swiveling path of the blocking section 107 relative to the movement of the thread section 108 of the lever 105 along the axle element 104 changes. The rotation pin 106 forms a rotation axis of the lever 105, wherein the rotation axis is for example not parallel to the rotation axis 117 of the rope drum/axle element and a radial direction of the rotation axis of the rope drum/axle element.

(41) The adjustment of the rotation pin 106 relative to the support structure 101 may also be used to manually release the blocking position of the lever 105, in order to enable an anew reeling of the rope drum 102.

(42) For example, at a first position of the deflection point 106 after a first number of rotations of the rope drum 102, the blocking position of the lever 105 may be reached, while at a second position of the deflection point 106 after another second number of rotations of the rope drum 102, the blocking position of the lever 105 may be reached. Thus, the unreelable rope length of the safety rope 103 can be adjusted by the shifting of the deflection point 106 of the lever 105, because the unreelable rope length is proportional to the number of the rotations of the rope drum 102 up to the reaching of the blocking position.

(43) The rotation pin 106 is coupled to a slider (or pusher) 110 as an actuation means. The slider 110 is configured to adjust the rotation pin 106 relative to the support structure 101.

(44) The slider 110 has a snap section 122 and the support structure 101 has a further snap section 120 (see the embodiment example in FIG. 2B). The snap section 122 and the further snap section 120 are formed such that the rotation pin 106 is adjustable relative to the support structure 101 by actuating the slider and is fixable to the further snap section 120 at a defined position by a catching mechanism of the snap section 122. The slider 110 is configured such that, upon pushing the slider 110, the snap section 122 and the further snap section 120 are decoupled and, upon a simultaneous shifting of the slider 110, an adjustment of the deflection point 106 is effected. The slider 110 has a return force, which is generated for example by means of a spring or by the elastic deformation behaviour thereof (of the slider), such that, by the slider 110, the snap section 122 and the further snap section 120 are coupled again after disabling the pushing movement, and a further shifting of the deflection point 106 is disabled.

(45) Alternatively to the snapping adjustment described above, also and as shown in FIG. 2B, an adjustment screw 202 may be arranged at the support structure, wherein the adjustment screw 202 can be screwed into the actuating means 110 as the slider, and accordingly forms a thread connection with the actuating means 110. Accordingly, the actuating means 110 can be shifted by screwing the adjustment screw 202 as the actuating means 110, and thus, an adjustability of the deflection point 106 can be implemented.

(46) In FIG. 3A to FIG. 3D, a centrifugal force element 302 of the securing device 100 is shown. The centrifugal force element 302 is arranged movably at the rope drum 102. Upon rotation, in particular at (or as from) a predetermined rotation speed, of the rope drum 102, the centrifugal force element 302 is movable radially outwardly (with respect to the rotation axis 117 of the rope drum 102), such that at (or as from) a predetermined rotation speed of the rope drum 102, a form-fit with the support structure 101 can be established. The form-fit of the centrifugal force element 302 with the support structure 101 results in a disabling of the rotation of the rope drum 102, and thus in a stop of the unreeling of the safety rope 103.

(47) Upon a downfall or upon a quick pulling on the ribbon/safety rope 103, the centrifugal force latches of the centrifugal force element 302 are moved out in order to block the rope drum. The blocking by the centrifugal force latches 302 is independent from the adjustment of the actuating means 110.

(48) For this purpose, the support structure 101 has a corresponding interior toothing 304, into which the centrifugal force element 302 engages at a defined rotation speed of the rope drum 102.

(49) The centrifugal force element 302 is arranged pivotably at the rope drum 102, such that at (or as from) a predetermined rotation speed of the rope drum 102, the centrifugal force element 302 swivels radially outwardly and establishes a form-fit with the interior toothing 304 of the support structure 101. The rotation speed of the rope drum 102, as from which the centrifugal force elements 302 swivel outwardly, may be adjusted by corresponding return forces of springs 305, which are arranged between the rope drum 102 and the centrifugal force element 302. Alternatively, the return forces may be adjusted by magnets, which may be arranged correspondingly at the rope drum 102 and at the centrifugal force elements 302.

(50) FIG. 3A to FIG. 3D further show that the rope drum 102 has a toothed ring 303. The toothed ring 303 is attached torque-proofly to the axle element 104 and thus rotates together with the rope drum 102. The toothed ring 303 has an outer toothing, wherein the outer toothing forms the snap notches 301.

(51) In FIG. 3D, the securing device 100 is represented without the support structure 101. The rope drum 102 may have e.g. two toothed rings 303, 303, which are spaced apart and between which the reeling path 123 runs (or extends).

(52) The safety rope 103 may be guided through the housing exits 306, 307 of the support structure 101 and through the rope drum 102, as is represented schematically e.g. in FIG. 6. Rollers 308, along which the safety rope 103 may roll along, are arranged around friction points between the safety rope 103 and the housing exits 306, 307.

(53) FIG. 4 shows a magnified section of the embodiment of FIG. 3A, wherein the lever 105 is present in the blocking position and thus presses on the snap cam 121. The snap cam 121 in turn engages accordingly in the snap notch 301 of the toothed ring 303, such that a rotation of the rope drum 102 is disabled.

(54) The snap cam 121 and the snap notch 301 are configured such that a wedging occurs in a first rotation direction of the rope drum 102 (in the clockwise direction in FIG. 4) and that a rotation and/or a free-wheeling of the rope drum 102 of the type of a free-wheeling of a clamping body is possible in a second rotation direction, which is opposite to the first rotation direction, of the rope drum 102 (in the counter-clockwise direction in FIG. 4).

(55) FIG. 5 shows an exterior representation of the securing device 100 according to the embodiment examples of FIG. 1 to FIG. 4. The support structure 101 is a housing, which houses the essential elements, such as for example the rope drum 102, the axle element 104 and the lever 105. The safety rope 103 is guided through an opening of the support structure 101, for example through the exits 306 and/or 307 of the housing, to the rope drum 102. The safety rope 103 may be guided through the rope drum 102, as is illustrated in FIG. 6. Alternatively, a securing element 501, such as for example a further safety rope, may be attached to the support structure 101. To one side, i.e. either to the safety rope 103 or to the securing element 501, the person to be secured may be attached, and to the other side, i.e. correspondingly to the safety rope 103 or to the securing element 501, the support structure 101 can be attached to a load-bearing structure, such as for example a wall or a support.

(56) Furthermore, the slider 110 is illustrated as an actuating means, which slider extends through the housing as the support structure 101, and which is actuable from the outside in the exterior of the housing. Thus, the unreeling length of the safety rope 103 can be adjusted flexibly.

(57) In FIG. 6, there is described a further embodiment of the rope securing device 100, in which the safety rope 103 is guided through the housing exits 306, 307 of the support structure 101 and through the rope drum 102. The rope drum 102 has a reeling path 123 along a circumferential direction 606 of the rope drum 102, along which reeling path the safety rope 103 is reelable (or can be reeled). The reeling path 123 further has a first opening 601 for rope and a second opening 602 for rope, which is formed along the circumferential direction 606 spaced apart from the first opening 601 for rope. The first opening 601 for rope and the second opening 602 for rope are formed such that the safety rope 103 is guidable through the rope drum 102, and such that upon rotation of the rope drum 102 both opposing rope ends 607, 608 of the safety rope 103 are simultaneously reelable and unreelable (or can be reeled and can be unreeled). The axle element 104 further has a gap or slit, through which the safety rope 103 can be guided between the first opening 601 for rope and the second opening 602 for rope.

(58) As from a predetermined number of rotations of the rope drum 102 and correspondingly as from a defined unreeling length of the first rope end 607 and the second rope end 608, the lever 105 presses on the snap cam 121, according to the embodiment example of FIG. 1 to FIG. 4, which disables a further rotation of the rope drum 102 with respect to the support structure 101, either by a form-fit and/or a friction fit.

(59) Due to the guiding through the rope drum 102 and/or the reeling path 123 thereof, the safety rope 103 is not anchored load-bearingly on the rope drum 102, but extends (or runs) through the latter. Thus, a direct connection exists e.g. between an attachment point 604 and a further attachment point 605, to which e.g. the person to be secured is attached, such that also the flux of force runs directly between the person to be secured and the attachment point 604. Thus, the securing device 100 has more or less only a reeling function and must transmit lower forces.

(60) Supplementarily, it is noted that having (or comprising) does not exclude other elements or steps, and that a or an does not exclude a plurality. In addition, it is noted that features or steps, which have been described with reference to one of the embodiment examples above, may also be used in combination with other features or steps of other embodiment examples described above. Reference numerals in the claims are not to be construed as limitations.
