DESCRIPTION OF THE INVENTION
(25)
(26) Various embodiments of such toggle lever closures 1 will be explained below, wherein reference should already be made here to the fact that such toggle lever closures can be used in an entirely different manner and to this extent are not restricted to the use of orthopedic aids. Toggle lever closures 1 can be used, for example, in general for tensioning a strap or belt, for example as a closure of a container or else as a closure for a sports shoe, for example a ski boot.
(27) In an embodiment of a toggle lever closure 1 that is illustrated in
(28) In the embodiment illustrated, the second closure element 11 and the first closure element 10 are releasable from each other. In order to close the toggle lever closure 1, the second closure element 11 is attached by the engagement portion 112 to the fastening element 111, and therefore the engagement portion 112 comes to lie with a sliding surface 114 on the sliding surface 104 of the fastening element 101. After the attaching, the second closure element 11 is pivotable about a first pivot axis D1 in relation to the first closure element 10, as is illustrated in the transition from
(29) When the second closure element 11 is attached to the first closure element 10, the fastening element 101 of the first closure element 10 comes into engagement with an opening 111 on a pivoting part 110 of the second closure element 11. The attaching of the second closure element 11 to the first closure element 10 and the identifying of the engagement portion 112 with the fastening element 101 is magnetically assisted here by magnetic elements 103, 113 which are arranged, firstly, in the region of the fastening element 101 on the body 100 of the first closure element 10 and, secondly, in the region of the engagement portion 112 on the second closure element 11, as illustrated schematically in
(30) By contrast, the tensioning element 12 is pivotable about a second pivot axis D2 in relation to the second closure element 11. By pivoting of the second closure element 11 in relation to the first closure element 10, the tensioning element 12 is carried along, and therefore a tensile force is exerted on the tension element, which is attached to the tensioning element 12, and therefore the tension element 2 is tensioned.
(31) In the closed position, illustrated in
(32) A magnetic element 103′ is arranged on the body 100 of the first closure element 10 (in addition to the magnetic element 103), said magnetic element 103′ in the closed position lying in a magnetically attracting manner opposite a magnetic element 113′ (additional to the magnetic element 113) on the pivoting part 110 of the second closure element 11. The second closure element 11 is therefore magnetically held in the closed position, and therefore the position of the second closure element 11 in relation to the first closure element 10 is thereby fixed in the closed position.
(33) The magnetic attraction is preferably dimensioned in such a manner that an unintentional release, in particular under the action of a load acting on the tensioning element 12 via the tension element 2, is not readily possible, at any rate not without conscious opening of the second closure element 11.
(34) For the opening, the second closure element 11 can be pivoted back out of the position illustrated in
(35) In an embodiment of a toggle lever closure 1 that is illustrated in
(36) In the embodiment illustrated, a magnetic element 103 is arranged on the fastening element 101 in the region of the sliding surface 104, said magnetic element 103, when the second closure element 11 is attached, facing a magnetic element 113 on a transverse strut 116 of the second closure element 11. The magnetic element 113 can be designed as a permanent magnet or else as a ferromagnetic component and is opposite the magnetic element 103 on the fastening element 101 in a magnetically attracting manner.
(37) It is conceivable here to configure the magnetic element 103 of the fastening element 101 as a permanent magnet. In this case, the magnetic element 113 can be configured as a permanent magnet or else as a ferromagnetic component.
(38) However, it is also conceivable to design the magnetic element 103 as a ferromagnetic component. In this case, the magnetic element 113 is realized by a permanent magnet.
(39) If the magnetic element 103 is designed as a permanent magnet, a separate cylindrical magnetic element 113 can optionally also be omitted if the wire clip realizing the second closure element 11 is manufactured from a ferromagnetic material and thus itself interacts in a magnetically attracting manner with the magnetic element 103.
(40) Remotely from the magnetic element 113, the second closure element 11 in the form of the wire clip is connected in an articulated manner to a tensioning element 12 on which a tension element 2, for example in the form of a strap or tape, is arranged. The toggle lever closure 1 serves for tensioning the tensioning element 12 by the second closure element 11, as is illustrated in the transition between
(41) In the closed position, illustrated in
(42) In the closed position, the second closure element 11 is therefore latched to the first closure element 10. The tensioning element 12 is also held in position via the second closure element 11, and therefore the toggle lever closure 1 is fixed in its closed position.
(43) In order to release the toggle lever closure 1, the second closure element 11 can be released from the latching, and therefore the second closure element 11 can be pivoted out of the position according to
(44) A closure device of the type illustrated in
(45) In this case, a latching device is not required. The closure is closed by simple hooking of the second closure element 11 into the first closure element 10.
(46) In an embodiment of a toggle lever closure 1 that is illustrated in
(47) A pivoting part 110 is connected in an articulated manner pivotably about the first pivot axis D1—to the attachment element 117, said pivoting part being extended with arms 118, 119 from the attachment element 117 and being connected to a connecting portion 123 of a tensioning element 12 via said arms 118, 119.
(48) In order to close the toggle lever closure 1, the attachment element 117 is attached to the first closure element 10 such that the attachment element 117 enters with an engagement portion 112 into engagement in the fastening element 101 and the projection 112 arranged thereon, as is illustrated in
(49) Both the attachment element 117 and the body 100 of the first closure element 10 each have a magnetic element here, and therefore the attachment element 117 is attached to the body 100 in a magnetically assisted manner. The attachment element 117 is attracted by the body 100, and therefore the attachment element 117 enters in a magnetically assisted manner into the position illustrated in
(50) If the attachment element 117 has been attached to the first closure element 10, the pivoting part 110 can be pivoted about the first pivot axis D1 in relation to the attachment element 117 in order thereby to tension the tensioning element 12 with the tension element 2 arranged thereon, as is illustrated in the transition from
(51) The pivoting part 110 is pivoted here in a pivoting direction S1 about the first pivot axis D1 in relation to the attachment element 117 and therefore in relation to the first closure element 10, wherein the tensioning element 12 is pivoted in a pivoting direction S2 about the second pivot axis D2 in relation to the pivoting part 110, as is apparent in the transition from
(52) A handle 122 on which a user can act, in order to close the toggle lever closure 1 or else to open same again, is mounted on the tensioning element 12. A user can thus pull on the handle 142 for opening purposes and can therefore lift the tensioning element 12 such that the pivoting part 110 is pivoted back about the first pivot axis D1 and also the tensioning element 12 is pivoted about the pivot axis D2.
(53) In the embodiment according to
(54) In said preferred position, illustrated in
(55) The ends 118A, 119A can act here on the tensioning element 12, for example in mutually offset openings on both sides of the connecting portion 123, and therefore the arms 118, 119 are held via their ends 118A, 119A at a distance A from each other on the connecting portion 123.
(56) The pivoting part 110 can also be pretensioned in relation to the tensioning element 12 in another way, for example via a leg spring which acts about the second pivot axis D2 and pretensions the pivoting part 110 in the direction of a preferred position in relation to the tensioning element 12.
(57) In the case of an embodiment of a toggle lever closure 1 that is illustrated in
(58) The first closure element 10 has a magnetic element 103, as is apparent from
(59) Both the first closure element 10 and the attachment element 117 can have a magnetic element in the form of a permanent magnet here. However, it is also conceivable and possible for one of the elements to have a permanent magnet and the other of the elements to have a ferromagnetic anchor.
(60) The closing of the toggle lever closure 1 takes place entirely analogously as described previously for the embodiment according to
(61) A latching device 124 in the form of two hooks is formed on a connecting portion 123, to which the pivoting part 110 of the second closure element 11 is attached in an articulated manner about the second pivot axis D2, said hooks, in the closed position of the toggle lever closure 1, being in engagement with a latching device 105 in the form of two latching recesses 106 of the first closure element 10 such that the tensioning element 12 is latched in relation to the first closure element 10. The toggle lever closure 1 is therefore secured in the closed position and cannot readily, at any rate not unintentionally, be opened under the action of load forces on the tension element 2.
(62) In the embodiment illustrated, an operating element 13 in the form of a release tab, on which a user can pull in order to open the toggle lever closure 1, is arranged on the attachment element 117. By lifting of the tensioning element 12 by way of a handle 122 and by pulling on the operating element 13, the toggle lever closure 1 can be opened and the attachment element 117 released from the first closure element 10.
(63) It is also conceivable and possible here, in a modified refinement, not to provide any handle 122 on the tensioning element 12, but rather to allow the operating element 13 to project below the tensioning element 12 in the closed position. Then, by pulling on the operating element 13, in one movement sequence the tensioning element 12 can be lifted and the attachment element 117 released from the first closure element 10.
(64) In the embodiments described above, the engagement portion 112 is extended rectilinearly along the first pivot axis D1. However, this is not limiting. Other configurations of the engagement portion 112 are also conceivable.
(65) For example, the engagement portion 112 can form a V shape, as is illustrated schematically in
(66) In this case, the attachment element can be designed as is described, for example, in WO 2014/090926 A1.
(67) In the embodiments described above, the second closure element 11 is to be (releasably) attached to the first closure element 10 in order to close the toggle lever closure 1. During the opening of the toggle lever closure 1, the second closure element 11 can be removed from the first closure element 10 in order thereby to release the connection between the second closure element 11 and the first closure element 10.
(68) In another refinement, illustrated schematically in
(69) It is also conceivable, in a modified refinement, in the embodiment according to
(70) The concept on which the solution is based is not restricted to the embodiments described above, but rather can basically also be realized in an entirely different manner.
(71) A toggle lever closure of the type described here is usable in an entirely different manner for the tensioning connection of parts to one another. One application can reside in the fastening of an orthopedic aid, for example an orthosis, to a patient, wherein, in this case, the orthopedic aid is arranged on an extremity of the patient in a tensioned manner by means of one or more toggle lever closures. However, a toggle lever closure of the type described here can also be used, for example, for closing a container, for example a crate or a bag, or for closing a sports shoe, for example a ski boot.
