Description

The present invention relates to a closure tensioner which comprises a foot part, a tensioning lever which can be pivoted relative to the foot part and a tensioning element which can be pivoted relative to the tensioning lever and which engages behind a counterholder in a tensioning position.

Such a closure tensioner is for example from the EP 1 169 235 B1 known.

This known Verschlussspanner is hand grip side provided with a hand-operated lever to the clamping element after it has been released by a pivoting movement of the clamping lever from its clamping position on the anvil can move into an open position in which the clamping element is lifted from the anvil.

In this known closure tensioner, however, the hand-operated lever, for example, with the thumb of the handle of the Verschluß spanner enclosing the hand of an operator, must be operated in addition to the clamping lever to transfer the clamping element in the open position.

The US 4,181,333 A and the US 4 531 769A disclose closure tensioner according to the preamble of claim 1.

The EP 2 233 024 A1 discloses a buckle tensioner for a sports shoe comprising a foot portion, a tension lever pivotable relative to the foot portion, and a tension member pivotable relative to the tension lever which engages an anvil in a cocking position, the bolt tensioner comprising a cam coupled to the tension lever and releasably coupled with the clamping element.

The present invention has for its object to provide a closure tensioner of the type mentioned, in which the transfer of the clamping element in the open position is particularly easy to carry out.

This object is achieved by a closure clamp according to claim 1.

The solution according to the invention is thus based on the concept of coupling the tensioning element of the closure tensioner by means of the catch which can be releasably coupled to the tensioning element, which in turn is coupled with the tensioning lever, to the tensioning lever such that the tensioning element of the pivotal movement of the tensioning lever is in the open position, so that no additional lever must be operated to transfer the clamping element in the open position.

The fact that the driver is detachably coupled to the clamping element, it is achieved that the clamping element is independent of the clamping lever movable after releasing this coupling.

In this way, in particular, the clamping element, in preparation for a clamping operation of the closure clamp, be moved back to the anvil before the clamping lever is moved out of its open position.

Further, the transfer of the clamping element and the clamping lever in the respective clamping position is preferably not complicated by a permanent coupling between the clamping element and the clamping lever.

In a preferred embodiment of the invention, it is provided that the clamping element is pivotable in the coupled state with the driver by a pivoting movement of the clamping lever in the open position.

The driver can basically be coupled in any way with the clamping lever, as long as the coupling is formed in such a way that the driver is also moved in the pivoting movement of the clamping lever in its open position.

This coupling is particularly simple when the driver is arranged on the clamping lever.

Furthermore, the coupling of the driver to the clamping element, before the transfer of the clamping element in its open position by means of the driver, basically done in any way.

In a preferred embodiment of the invention it is provided that the driver can be coupled by a pivoting movement of the clamping lever with the clamping element.

It is particularly advantageous if the driver can be coupled to the clamping element in an intermediate position of the clamping element in which the clamping element is released from the clamping position. This ensures that the movement of the clamping element from the clamping position in this intermediate position is not complicated by the coupling of the clamping element with the driver.

Preferably, the clamping element is in the intermediate position with the anvil in contact.

In the open position, the clamping element is preferably lifted from the counter-holder.

The tensioning element can in principle be designed in any desired manner.

In a preferred embodiment of the invention, the clamping element is designed as a, preferably substantially U-shaped, clamping bracket.

The coupling between the driver and the clamping element can in principle be formed in any way, as long as this coupling between the driver and the clamping element is releasable again.

Thus, for example, be provided that the driver can be coupled by adhesion to the clamping element.

The driver and / or the clamping element comprises a magnetic element. Thereby, the coupling between the clamping element and the driver can be produced by a magnetic attraction.

If the driver comprises a magnetic element, then the clamping element preferably comprises a magnetizable portion and / or a second magnetic element in order to be able to interact magnetically with the driver.

If the clamping element comprises a magnetic element, then the driver preferably comprises a magnetizable portion and / or a second magnetic element in order to be able to interact magnetically with the clamping element.

Alternatively or in addition to a coupling by frictional connection can also be provided that the driver can be coupled by positive engagement with the clamping element.

In particular, it can be provided that the driver and / or the clamping element comprises a latching element.

Furthermore, it can be provided that one of the elements driver and clamping element comprises a first latching element and the respective other of these elements comprises a second latching element which can be latched to the first latching element.

For the production of an effective coupling between the driver and the clamping element, in which an unintentional release of the coupling between the driver and the clamping element is avoided, it is advantageous if the closure clamp comprises a biasing element, which in the coupled state, the driver and / or the Clamping element biases in a detent position, in which the driver and the clamping element are coupled together by latching.

Such a biasing element may in particular comprise a spring element, for example a compression spring, a tension spring and / or a plate spring.

In order to solve the coupling between the driver and the clamping element in a simple manner again, when the clamping element has been transferred by the pivoting movement of the clamping lever in the open position, it is advantageous if the closure tensioner comprises an actuator, by the actuation of the driver and / or the clamping element from a detent position is releasable, in which the driver and the clamping element are locked together.

It can be provided in particular that the actuating element has a recess for receiving the clamping element and / or the driver.

In order to make the closure clamp easy to use for both right-handed and left-handed people, it is advantageous if the actuator is mounted in two different positions relative to the clamping lever, wherein the actuating element in a first position to the left of the clamping lever and in a second position is arranged to the right of the clamping lever.

The data "left of the clamping lever" and "right of the clamping lever" respectively refer to the left and right of a longitudinal center plane of the clamping lever, which is perpendicular to the pivot axis of the clamping lever, the viewing direction directed by the clamping lever to the anvil of the closing clamp is.

In a preferred embodiment of the invention it is provided that the driver is displaceable relative to the clamping lever in a transverse direction of the closure clamp.

This transverse direction is preferably aligned substantially parallel to the pivot axis of the clamping lever and / or substantially parallel to the pivot axis of the clamping element.

One in the 1 to 16 shown as a whole with 100 designated closure tensioner comprises a foot part 102 , one by means of a clamping lever bearing 104 swiveling on the foot part 102 held clamping lever 106 , by means of a clamping element bearing 108 pivotable on the clamping lever 106 held clamping element 110 and a backstop 112 that of the tensioning element 110 in one in the 1 to 4 illustrated clamping position of the closure tensioner 100 behind and against the foot part 102 of the closure tensioner 100 is clamped.

The foot part 102 may, for example, two foot angle elements 114 each of which in turn comprises a mounting leg 116 and a bearing leg 118 includes.

The attachment leg 116 may be one or more fastener passage openings 120 through which fastening means (not shown) can pass, with which the foot part 102 can be fixed to a (not shown) first ground.

The bearing legs 118 the two foot part angle elements 114 lie against each other and carry the tension lever bearing 104 , by means of which the tension lever 106 swiveling on the foot part 102 is held.

The tension lever 106 For example, two tension lever cheeks 122 include.

Each tension lever cheek 122 each has a bearing part 124 and a handle part 126 on that over a bend 128 connected to each other.

The handle parts 126 the tension lever cheeks 122 lie against each other and are of a handle 130 of the closure tensioner 100 surround.

The handle 130 serves to allow an operator to engage the same to the cocking lever 106 relative to the foot part 102 around his by the tension lever bearing 104 extending clamping lever pivot axis 132 to pan.

The bearing parts 124 the tension lever cheeks 122 are due to the offsets 128 in a parallel to the clamping lever pivot axis 132 extending transverse direction 134 of the closure tensioner 100 spaced apart and on each side of the foot part 102 arranged, wherein the mutually facing inner sides of the clamping lever cheeks 122 on the opposite outer sides of the bearing legs 118 of the foot part 102 issue.

At the bearing parts 124 the tension lever cheeks 122 is also the clamping element bearing 108 held.

The tensioning element bearing 108 includes a pivot pin 135 which the bearing parts 124 the tension lever cheeks 122 interspersed and about a clamping element pivot axis 136 is pivotally mounted.

The tensioning element 110 is for example as a U-shaped clamp 138 formed, whose free ends are through through holes in the pivot pin 135 therethrough.

These free ends are preferably each provided with an external thread on which on both sides of the pivot pin 135 one mother each 140 is screwed to the clamp 138 on the pivot pin 135 to secure.

The counterpart 112 includes a base plate 142 from which there are two side cheeks 144 extend away.

The base plate 142 has one or more fastener passage openings 146 on, by which (not shown) fastening means are guided, by means of which the counter-holder 112 can be fixed to a (not shown) second surface.

The side cheeks 144 of the counterpart 112 each include a retaining projection 148 and one at the foot part 102 of the closure tensioner 100 opposite side of the retaining projection 148 arranged recess 150 which, for example, substantially complementary to the cross section of the clamping element 110 is formed, so that in the in the 1 to 4 illustrated clamping position the clamping element 110 the retaining projections 148 of the counterpart 112 reach behind and in the recesses 150 can be included.

In this clamping position are the counter-holder 112 and the foot part 102 of the closure tensioner 100 by means of the tension element 110 braced against each other.

Furthermore, the closure tensioner comprises 100 a driver 152 , which, preferably rotationally fixed, on the clamping lever 106 is arranged.

The driver 152 includes a holding part 154 , which extends through through holes in the clamping lever cheeks 122 extends through and, preferably insoluble, with the clamping lever cheeks 122 is connected, and one of the holding part 154 in the transverse direction 134 of the closure tensioner 100 projecting driver projection 156 ,

The driver advantage 156 includes a magnetic element 158 attached to a tensioning element 110 facing side of the driving projection 156 is arranged.

The magnetic element 158 is preferably formed as a permanent magnet.

In principle, each element of the closure clamp 100 be formed of any material, which is responsible for the function of the closure tensioner 100 has sufficient mechanical strength.

The handle 130 and the driver 152 (except for the magnetic element 158 ) are preferably formed of a plastic material. The remaining components of the locking clamp 100 are preferably formed of a metallic material, in particular of a steel material.

The closure clamp described above 100 works as follows:
In the in the 1 to 4 illustrated clamping position of the closure tensioner 100 engages behind the tensioning element 110 the counterpart 112 and is secured in this clamping position characterized in that the tensioning lever 106 is in its dead center position or slightly below its dead center position.

In this clamping position is the clamping element 110 preferably substantially parallel to a longitudinal direction 160 of the closure tensioner 100 aligned, which of the foot part 102 to the counterpart 112 is directed and perpendicular to the transverse direction 134 of the closure tensioner 100 runs.

The driver 152 is in the clamping position on the mounting legs 116 of the foot part 102 opposite side of the clamping element 110 arranged and from the clamping element 110 spaced.

When an operator on the handle 130 of the closure tensioner 100 attacks and the handle 130 and thus the tension lever 106 (in the direction of the 2 and 6 seen in the counterclockwise direction) relative to the foot part 102 around the cocking lever pivot axis 132 over the dead center of the clamping lever 106 Swung out, so the clamping element 110 from the into the 1 to 4 solved clamping position and in the in the 5 to 8th shown transferred intermediate position, in which the clamping element 110 the recesses 150 of the counterpart 112 left, but still in contact with the counterpart 112 stands.

In this intermediate position is the magnetic element 158 of the driver 152 still from the clamping element 110 spaced so that the driver 152 and the tensioning element 110 not yet coupled with each other in this position.

By further pivoting the clamping lever 106 around the cocking lever pivot axis 132 (in the direction of the 6 and 10 seen in the counterclockwise direction) passes the magnetic element 158 in contact with the clamping element 110 , whereby a frictional coupling between the driver 152 and the tensioning element 110 will be produced. This is the in the 9 to 12 illustrated coupling state of the closure tensioner 100 reached.

Now if the operator the clamping lever 106 from the into the 9 to 12 illustrated coupling position in the in the 13 to 16 illustrated open position about the clamping lever pivot axis 132 swings back (in the direction of the 10 and 14 seen in a clockwise direction), this is caused by a magnetic attraction between the material of the clamping element 110 and the magnetic element 158 of the driver 152 with the driver 152 coupled clamping element 110 in this pivotal movement of the clamping lever 106 carried along and thus in his also in 13 to 16 illustrated open position transferred, in which the clamping element 110 from the counterpart 112 lifted off and on the counterhold 112 is spaced.

The longitudinal direction of the tensioning element 110 closes in the open position with the longitudinal direction 160 of the closure tensioner 100 preferably an angle of 45 ° or more.

To the closure tensioner 100 from in the 13 to 16 Open position shown again in the in the 1 to 4 transfer shown clamping position, the coupling between the clamping element 110 and the driver 152 solved by the operator the handle 130 on the cocking lever 106 holds and at the same time on the clamping element 110 attacks and the same to the clamping element pivot axis 136 to the counterpart 112 towards (in the direction of the 14 seen counterclockwise) pivots, with the clamping element 110 overcoming the magnetic attraction between the clamping element 110 and the magnetic element 158 from the magnetic element 158 solves.

One in the 17 to 28 illustrated second embodiment of a closure tensioner 100 is different from the one in the 1 to 16 shown first embodiment in that the driver 152 instead of a magnetic element 158 a locking element 162 includes, so the driver 152 by positive engagement releasable with the clamping element 110 can be coupled.

How best of the 19 and 20 can be seen includes the driver 152 on one side of a median longitudinal plane 164 of the closure tensioner 100 , which are perpendicular to the clamping lever pivot axis 132 and parallel to the longitudinal direction 160 of the closure tensioner 100 runs, the locking element 162 with a recess 166 for receiving a portion of the tensioning element 110 in the coupled state of drivers 152 and tensioning element 110 , wherein the latching recess 166 in the direction to the clamping element 110 through a locking projection 168 is limited.

On the opposite side of the median longitudinal plane 164 includes the driver 152 an actuator 170 , for example in the form of an actuating button 172 which preferably has a recess 174 for receiving a portion of the tensioning element 110 in the coupled state of drivers 152 and tensioning element 110 having.

The driver 152 is in the transverse direction 134 of the closure tensioner 100 slidable on the clamping lever 106 held.

The actuator 170 is at its the tension lever 106 facing end with a stop collar 176 Mistake. Between the stop collar 176 and the same facing outside of the clamping lever 106 is a spring element 178 , For example, in the form of a compression spring and / or a plate spring arranged.

The spring element 178 serves as a biasing element 182 and tensions the driver 152 in his example in 19 shown rest position in which the actuating element 170 its maximum distance from the cocking lever 106 occupies and the locking element 162 about another stop collar 180 on the opposite side of the clamping lever 106 is applied.

By exerting pressure on the actuator 170 in the transverse direction 134 is the driver 152 from this rest position against the restoring force of the spring element 178 slidable in a release position, in which the clamping element 110 in the recess 166 of the locking element 162 einbringbar or from the recess 166 is moved out.

The above-described second embodiment of the closure tensioner 100 works as follows:
In the in the 17 to 20 illustrated clamping position of the closure tensioner 100 engages behind the tensioning element 110 the counterpart 112 and passes through the recesses 150 of the counterpart 112 so that the counterpart 112 and the foot part 102 of the closure tensioner 100 through the clamping element 110 are braced against each other.

When an operator grasps the handle 130 and thus the tension lever 106 of the closure tensioner 100 from the clamping position around the clamping lever pivot axis 132 (in the direction of the 18 and 22 in the counterclockwise direction) in the in the 21 to 24 shown coupling position pivots, then the clamping element 110 released from the clamping position and transferred to an intermediate position, in which the clamping element 110 still at the counterpart 112 is applied.

Furthermore, the rotationally fixed with the clamping lever 106 connected drivers 152 on the clamping element 110 to move until the locking projection 168 of the locking element 162 in contact with the clamping element 110 comes. When further swinging the clamping lever 106 displaces the tensioning element 110 the locking projection 168 against the restoring force of the spring element 178 in the transverse direction 130 from the cocking lever 106 away, leaving the clamping element 110 in the recess 166 of the locking element 162 can get into it. If the entire cross section of the clamping element section in the recess 166 is picked up, moves the driver 152 due to the restoring force of the spring element 178 returns to its rest position, causing the driver 152 and the tensioning element 110 locked together.

Then, when the operator grips the handle 130 and thus the tension lever 106 from in the 21 to 24 illustrated coupling position about the clamping lever pivot axis 132 (in the direction of the 22 and 26 in a clockwise direction) into the 25 to 28 shown open position pivots, it will be by positive locking with the driver 152 coupled clamping element 110 by this pivoting movement of the clamping lever 106 which by the with the tension lever 106 connected driver 152 on the clamping element 110 is also transferred to its open position.

To the closure tensioner 100 from in the 25 to 28 Open position shown again in the in the 17 to 20 To be able to transfer shown clamping position, the coupling between the clamping element 110 and the driver 152 solved by the operator pressing on the actuating element 170 in the transverse direction 134 exercises, so the driver 152 against the restoring force of the spring element 178 in the transverse direction 134 of the closure tensioner 100 is shifted so that the locking projection 168 of the locking element 162 out of engagement with the clamping element 110 comes. Then the clamping element 110 (Under the action of gravity or by attacking an operator on the clamping element 110 ) from the recess 166 moved out and around the clamping element pivot axis 136 (in the direction of the 26 counterclockwise) until the clamping element 110 in contact with the counterpart 112 comes.

The in 17 to 28 illustrated closure tensioner 100 is intended for use by a left-hander, the one to the right of the median longitudinal plane 164 arranged actuator 170 with the thumb of the left hand can operate when the left hand the handle 130 embraces.

However, the closure clamp can be easily converted for use by a right-handed person by the driver 152 from the tension lever 106 loosened and returned to the clamping lever in a position rotated by 180 ° 106 is mounted so that the actuating element 170 then left of the median longitudinal plane 164 is arranged.

Incidentally, the right in the 17 to 28 illustrated second embodiment of the closure tensioner 100 in terms of structure and operation with in the 1 to 16 illustrated in the first embodiment, reference is made to the above description in this regard.
