Description

C,
Element for closing an opening, in particular an eye ring The invention relates to an element as described in the preamble of Claim 1.
An eye ring in accordance with FR 2 482 838 Al has already been disclosed which has a fastening tab and a ring element. A fastening means, in particular a rivet shaft, which joins the eye ring to an article, in particular an article of clothing, is integrally joined to the fastening tab, in particular formed onto the latter. The fastening tab furthermore has a bending tab which extends while facing away from the ring element and which is integrally joined to the fastening tab by a weakened area. In this connection, the bending tab is deformed from a position extending planarly with the fastening tab through 180' into a position parallel to the fastening tab and is located after deformation has taken place on an upper side of the fastening tab, which upper side faces away from the fastening means. This provides a two-layer structure of the fastening tab. The ring element has a circumferential beading with an approximately circular cross section and extends in a plane situated at an angle to the fastening tab. The disadvantage of this eye ring is that the fastening means, i.e. the rivet shaft, is integrally joined to the fastening tab, as a result of which a relative mobility of the eye ring in relation to the article of clothing, in particular a swivelability of the eye ring, takes place only as a result of a simultaneous swivelability of the fastening means joined, in particular riveted, to the article of clothing, as a result of which the article of clothing is severely stressed during the swivelling of the eye ring in the region of the rivet and in the event of frequent swivelling damage occurs to the article of clothing in the rivet area.
In addition, the tightness of the article of clothing is reduced to such an extent that moisture and dampness can penetrate the interior of the article of clothing via the internal bore of the fastening means. The covering of the fastening tab, in particular in the region of the fastening means by the bending tab is an inadequate remedy in this connection, since the bending tab is spaced apart from the upper side of the fastening .,vN facing the latter by a gap, which in turn permits the penetration of moisture and -2dampness. As a result of the flat extension of the fastening tab and the extension of the ring element at an angle to the latter, a bent area is produced which, with a corresponding tensile stressing of the pulling element, brings about a point or linear pressure loading of the article of clothing or on the part of the body of a person wearing the article of clothing, as a result of which the wearing comfort is substantially reduced because of the formation of pressure points on the respective part of the body.
The invention furthermore relates to an element as described in the preamble of Claim 2.
From US 1 442 468 A a clamping device is known which comprises a fixture body and a reversing element which is disposed pivotably in the latter and is in the form of an open frame. Formed onto the fixture body or joined to the latter is a button which is preferably hemispherical in shape, but at least convex, the button having no joining piece to the fixture body. A disadvantage of this design is that the reversing element is in the form of an open frame, as a result of which the latter is plastically deformed in the event of a tensile loading exerted on the reversing element by a pulling element, for example a shoelace. A further disadvantage is that clamping is achieved only by using an additional spring element which, if the tensile loading exerted by the shoelace is removed, brings about an automatic swivelling of the reversing element away from the button into a release position and, as a result, it is not possible, in particular, to achieve a different tensioning force in the pulling element in adjacent areas of the lacing, which would be indispensable for increasing the utilisation and wearing comfort.
As a result of the surfaces of the button and of the reversing element which extend convexly with respect to one another in the clamping area, only a linear pressing of the shoelace is achieved, as a result of which only low tensile forces can act on the shoelace to achieve a reliable clamping.
Finally, the invention also relates to a closure system for closing an opening with at 0 least one lace-type or ribbon-type pulling element, for example a shoelace, a shoe ribbon, a cord, as described in the preamble of Claim 34.
Various closure systems for closing openings, for example for closing the instep openings in the case of shoes, openings in articles of clothing or of rucksacks etc. are already known which have at least one lace-type tying element. In this connection, there are disposed over the extension of the opening on mutually opposite sides similar reversing fixtures for the pulling element, in particular in the form of eye rings which mostly result in considerable wear of the pulling element owing to a small gap between the eye ring and the surface, for example of the shoe, as a result of the frictional forces resulting when the pulling element passes through. Furthermore, there is no possibility of a locally variable pulling tension in the pulling element across the extension of the opening.
According to one aspect of the invention there is provided an element for closing an opening, in particular an eye ring, for receiving at least one lace-type or ribbon-type pulling element, for example a shoelace, a shoe ribbon or a cord, having a fastening tab for at least one fastening means o designed as, for example, as rivet, seam, adhesive joint or weld and having a .reversing element which is formed by a web which extends in loop shape and which forms the boundary, with the fastening tab, of a threading opening for the pulling element, characterised in that the web of the fastening tab has adjacent subareas and a first subarea encloses an obtuse pitch angle with a contact surface or a surface of the fastening tab, and is delineated by a bend area which is spaced apart from the fastening tab and from which the further *subarea of the web projects oppositely to the fastening tab, the lower side of which web and a part a plane receiving the lower side of the first subarea, 25 which part projects beyond the lower side in the direction of the further subarea, enclose an acute pitch angle.
The surprising advantages of said achievement are, on one hand, the frictionless threading of the pulling element, as a result of which the wear of the pulling element and of the element or of the article is reduced and, as a result of mninimising the frictional resistance, the tensile forces necessary to close the opening can be kept low. In addition, an orthopaedically beneficial form of the element is achieved which adjusts to the external contour of the article, as a result of which pressure points on the body part of a person wearing the article are avoided and the wearing comfort is thereby increased.
The greater rigidity of the element in addition brings about a reduction in the elastic deformability, as a result of which an unintentional detachment is avoided.
It is therefore an advantageous feature to provide elements or a closure system for closing an opening with at least one lace-type or ribbon-type pulling element which opening increases the wearing comfort of an article having the opening, such as, for example, a shoe, a jacket, a rucksack etc., and/or the ease of use on opening and/or closing the opening of the article.
According to a second aspect of the invention there is provided element for closing an opening, in particular a clamping device for at least one lace-type or ribbon-type pulling element, for example a shoelace, a shoe ribbon or a cord, having a fastening tab for at least one fastening means designed, for example, as rivet, seam, adhesive joint or weld and having a swivel-bearing fixture with a swivel axis extending parallel to a contact surface of the fastening tab for a swivellable reversing element and having a clamping body which, with the reversing element situated approximately S: parallel to the contact surface, is encompassed by said reversing element at least locally, characterised in that the clamping body has, at an end face facing the swivel-bearing fixture, a slot-type recess extending approximately 20 parallel to the contact surface.
The surprising advantages of this design are that, in the stressed state of pulling the element, an unintentional release of the latter and consequently an unintentional opening 9 -4of the slot-type opening are avoided. Furthermore, a relative movability of the reversing element in relation to the clamping body is achieved, as a result of which a gap between the reversing element and the clamping body, in particular during swivelling of the reversing element into a clamping position, can be increased, which results only in a slight squashing of the pulling element. This results in a reduction in wear of the pulling element, in particular in the event of frequent swivelling of the reversing element. In addition, the force which is necessary to swivel the reversing element with the pulling element wrapped round into the clamping position is reduced, as a result of which the utilisation comfort is increased, in particular during the swivelling of the reversing element into the clamping position or into the release position.
In this connection, a development according to Claim 3 is of advantage, as a result of which a simple deformation of the web or of its subareas is achieved and, in particular no spatial deformation of the web is necessary, but deformations which are situated in each case in specific planes.
An embodiment according to Claim 4 is also advantageous, as a result of which a friction loading is avoided during threading of the pulling elements through the eye ring is avoided and, consequently, the lifetime of the pulling element is substantially increased,.
An advantageous development is described in Claim 5, in which additional working steps are avoided, and consequently the eye ring can be produced inexpensively.
A design variant according to Claim 6 has the advantage that the rigidity of the web is increased with the lowest possible usage of material.
However, an embodiment according to Claim 7 is also possible, in which an optimum matching of the eye ring to the supporting plane of the article is achieved, as a result of which the eye ring and, consequently, the article can be of beneficial design ortho- 'S -aedically.
aedic ally.
Flu% However, a development according to Claim 8 is also advantageous, in which the threading of the pulling element through the eye ring is further improved and the wear of the pulling element is further reduced.
Claim 9 describes a beneficial design variant, which makes possible a uniform threading of the pulling element through the eye ring in various directions.
A design variant according to Claim 10 has the advantage that the pulling element can easily be threaded into the eye ring.
An embodiment according to Claim 11 is also advantageous, which permits a simple production of the eye ring.
Claim 12 describes an advantageous development, as a result.of which the weather resistance of the eye ring and, consequently, its durability, are substantially increased.
A design according to Claim 13 is also beneficial, as a result of which the production of an integral eye ring, in particular from an integral, flat blank, is facilitated.
A design variant according to Claim 14 is of advantage, as a result of which the rigidity is increased, which has the result that higher tensile forces can be exerted on the pulling element and consequently on the eye ring.
Claim 15 describes a beneficial development which makes possible a production of the clamping device which is simple in terms of shape engineering and achieves a uniform deformability, especially in the pulling direction of the pulling element as a result of the weakening of the clamping body.
A design variant according to Claim 16 is advantageous because this makes it possible to resolve forces acting on the clamping body into horizontal and vertical components BUS thereby produce a widening of the recess and, consequently, a change in the distance between reversing element and clamping body in a simple manner.
However, a development according to Claim 17 is also beneficial, as a result of which the pulling element can be clamped and, consequently, different tensions can be achieved in the pulling element.
Claims 18 and 19 describe in an advantageous manner a clamping ability of the pulling element, which is pressed flatly and, consequently, the clamping is achieved without unnecessarily high wear of the pulling element.
A design element according to Claim 20 is also advantageous, in which the clamping ability is also achieved if the pulling element, i.e. the part entering the reversing element and the part of the pulling element emerging from the latter have different direc-.
tions or the pulling element is not introduced axially into the reversing element, i.e. in the direction of the longitudinal middle axis of the element.
A development according to Claim 21 has the advantage that the clamping increases, the further the direction of the pulling element in the reversing element deviates from a position directed axially in the direction of the longitudinal middle axis. A design variant according to Claim 22 in which the clamping device can be produced simply by manufacturing engineering and manufacturing costs can thereby be reduced is furthermore possible.
However, an embodiment according to Claim 23 is also advantageous, which achieves the result that the clamping surface of the clamping body is greater than that of the reversing element and, consequently, a lower surface pressure is achieved on the clamping body, which brings about a lower wear, in particular if a clamping body made of plastic is used.
0 Adevelopment according to Claim 24 has the advantage that the reversing element b be swivelled over the clamping body in a simple manner.
((F
A design variant according to Claim 25 is also advantageous, in which a swivel-bearing fixture design as bending element is avoided and such a swivel bearing can be achieved in the clamping body itself with minor additional expenditure, as a result of which the material and manufacturing expenditure of a clamping device according to the invention can be reduced further.
A variant according to Claim 26 is likewise possible, a swivel-bearing fixture being provided with a higher strength which, in addition, can be locked against relative movability with respect to the fastening tab.
An embodiment according to Claim 27 is also of advantage, in which the clamping device can be produced in a simple manner by production engineering.
By means of Claims 30 and 31 it is possible for pulling elements which have a circular cross section also to be capable of being clamped without the lace-type pulling elements having a greater deformation resistance being exposed to excessively sever deformation and, consequently, to excessively severe wear. At the same time, however, ribbon-type pulling elements can also be alternatively be clamped in a simple manner.
Finally, the developments according to Claims 32 and 33 are of advantage, as a result of which a relative movability of the elements with respect to the articles, such as, for example, shoes, jackets, etc. is avoided.
According to a third aspect of the invention, there is provided closure system for closing an opening with at least one lace-type or ribbon-type pulling **element, for example a shoelace, a shoe ribbon or a cord, characterised in that the pulling elemnent is threaded through a plurality of eye rings disposed along 25 the opening and spaced apart from one another and is clamped in one or more clamping devices disposed along the opening preferably between the eye rings and formed by elements and in that the clamping device has a fastening tab and a swivel-bearing fixture having a swivel axis, extending parallel to a contact surface for a swivellable reversing element and a clamping body and which, in a position of the reversing element situated approximately parallel to the contact surface, is encompassed at least locally by said reversing element.
This is also advantageous since different areas of the pulling element can thereby be acted on by different stresses, as a result of which a surface pressure adjusted, for example to the sensitivity of the body part, is achieved and the wearing comfort of an article and also the utilisation comfort of -8the closure system are thus substantially increased.
Finally, a design according to Claims 35 and 36 is also of advantage since the stresses in the case of such closure systems can consequently be adjusted at the desired points in the opening.
For a better understanding of the invention, the latter is explained in more detail below by reference to the exemplary embodiment shown in the drawings.
In the drawings: Figure 1 shows an element according to the invention for closing an opening, in particular an eye ring, in plan view; Figure 2 shows the element according to the invention sectioned along the lines II-II in Figure 1; Figure 3 Figure 4 shows a further design variant of an element for closing an opening, in particular an eye ring, in plan view; shows the element according to the invention, sectioned along the lines IV-IV in Figure 3; shows the element according to the invention, sectioned along the lines V-V in Figure 3; Figure 5 Figure 6 shows a further design variant of an element for closing an opening, in particular an eye ring, in plan view; Figure 7 shows the element according to the invention, sectioned along the lines VII-VII in Figure 6; -9- Figure 8 shows an element according to the invention for closing an opening, in particular a clamping device, in plan view; Figure 9 shows the element according to the invention, sectioned along the lines IX-IX in Figure 8; Figure 10 shows a further design variant of an element according to the invention for closing an opening, in particular a clamping device, in plan view; Figure 11 shows the element according to the invention, sectioned along the lines XI-XI in Figure Figure 12 shows the closure system according to the invention for closing an opening in a perspective view.
The jointly described Figures 1 and 2 show an element 1 for closing an opening 2, in particular an eye ring 3, which has a fastening tab 4 and a reversing element 5 for reversing a lace-type or ribbon-type pulling element 6, for example a shoelace, a shoe ribbon, a cord, etc. In this connection, the reversing element 5 is formed from a looptype web 7 which, in the present exemplary embodiment, has a U-shaped contour and projects beyond the fastening tab 4, for example in the direction of the opening 2. The web 7, in particular an internal contour 8 and a fastening tab 4 form the boundary, in the direction of the end face 9 delineating the reversing element 5, of a threading opening 10 through which the pulling element 6 is passed.
The fastening tab 4 comprises a preferably planar base plate 11 which fits against a supporting plane 13 of an article 14, for example an article of clothing, a rucksack, a f shoe, having an opening, by means of a contact surface 12. Facing away from the -ontact surface 12, the fastening tab 4 is delineated by a surface 15 which extends approximately parallel to the contact surface 12 and is spaced apart from the latter by a base plate thickness 16 by the end face 9 in an area assigned to the reversing element The contact surface 12 may, however, also be of curved design, as a result of which a better fit to a supporting plane 13 of curved design can be achieved.
In the present exemplary embodiment, the fastening tab 4 has a reinforcing rib 17.
However, it can also be of planar design, i.e. without a reinforcing rib 17. The reinforcing rib 17 forms the boundary of the base plate 11 in C-shaped fashion and has, for example, an arch-shaped cross section. An upper side 18 delineating the reinforcing rib 17 in the opposite direction to the article 14 is spaced apart from the surface of the ground plate 11 by a rib height 19. The element 1 has a longitudinal middle axis 20 which forms, by means of a transverse axis 21 disposed at right angles to the latter, a centre 22 for, for example, a perforation 23 for receiving a fastening means 24, for example a rivet. A middle axis 25 of the fastening means 24 extends at right angles to the surface 15 in the centre 22. The base plate 11 has a plate width 26, measured at right angles to the longitudinal middle axis 20, which is delineated by two longitudinal ribs 27 which form parts of the reinforcing rib 17, preferably disposed symmetrically around the longitudinal middle axis 20 and which have a rib width 28 which projects beyond the plate width 26 in the direction opposite to the longitudinal middle axis 20. In an area of the base plate 11 facing away from the end face 9, said base plate 11 is delineated by a transverse rib 29 extending, for example, in archshaped fashion around the centre 22 and which joins the longitudinal ribs 27 together and has a transverse rib width 30 which is, for example, greater than the rib width 28 and which is measured horizontally in the longitudinal middle axis 20. The reinforcing rib 17, i.e. the longitudinal ribs 27 and the transverse rib 29 have a concave cross section with respect to the contact surface 12. The reinforcing rib 17 is preferably formed integrally on the base plate 11.
The reversing element 5, i.e. the web 7, comprises, for example, longitudinal webs 31 x~tending symmetrically with respect to the longitudinal middle axis 20 and a transse web 32 which is, for example, of circular-arc design. The longitudinal webs 31 -11 may have a straight or curved contour 8 and are spaced apart from one another by an opening width 33 measured at right angles to the longitudinal middle axis 20, which is equal to the plate width 26. In this connection, the longitudinal ribs 31 are designed, in particular, as continuations of the reinforcing rib 17, in particular the longitudinal ribs 27, projecting in the direction of the slot-type opening 2 and are integrally joined to said longitudinal ribs 27. The web 7 may, however, also be designed so that the longitudinal webs 31 extend in circular-arc fashion with respect to one another, as a result of which the curved transverse web 32 is replaced by the two longitudinal webs 31 of circular-arc design.
Figure 2 shows that the longitudinal webs 31 extend angularly in the direction of the opening 2 and of the supporting plane 13 of the article 14 from a leading edge 34 formed by the end face 9 and the surface 15 up,to.a bend area 35 which is spaced apart from the end face 9 in the direction of the opening 2. A lower side 36 of the longitudinal web 31, which lower side 36 faces the supporting plane 13, forms, together with the surface 15, a pitch angle 37 which is 900 to 1800, preferably 1550. It is, however, also possible for the longitudinal web 31 also to extend in an inclined manner in the direction of the slot-type opening 2 and of the supporting plane from a lower edge 38 formed by the contact surface 12 and the end face 9, the lower side 36 enclosing in this case the pitch angle 37 with the contact surface 12.
The bend area 35 forms the joint area between the longitudinal web 31 and the transverse web 32, which extends in an inclined manner in the opposite direction to the supporting plane 13 and in the direction of the opening 2. An lower side 39 of the transverse rib 32 encloses, with the supporting plane 13, a pitch angle 40 which is between 50 and 850, preferably 270. The cross section of the web 7 is designed in hollow-profile shape, for example as an oval curled section 41. The pitch angle 41 is to be chosen, in particular, so that, as a function of a distance 42 of the contour 8 of the transverse web 32 from a contact edge 43 of the bend area 35, i.e. of the lower side 36 with the supporting plane 13 of the article 14, a threading height 44 is formed -12which is measured at right angles to the supporting plane 13 in the direction opposite to the latter and spaces apart a contour point 45 nearest said supporting plane 13 and which is greater than a thickness 46 of the pulling element 6 measured parallel to said supporting surface 13. In this connection, the distance 42, the threading height 44 and the contour point 45 lie in a plane extending preferably in the longitudinal middle axis at right angles to the supporting plane 13.
The jointly described Figures 3 and 5 show a further embodiment of the element 1 according to the invention, in particular an eye ring 3. This again comprises a fastening tab 4 and a reversing element 5 which are integrally joined, in particular formed, welded or glued onto the fastening tab 4. The fastening tab 4 has a base plate 11 having a base plate thickness 16 which is delineated by the contact surface 12 and the surface 15. The base plate 11 has, for example, two circular perforations 23 whose centres 22 are spaced apart from one another by a distance 47 along a longitudinal middle axis 20 of the eye ring 3. An end face 9 preferably extending in an inclined manner to the surface 15 or the contact surface 12 and facing the reversing element forms, with the contact surface 12, a lower edge 38 which delineates the base plate 11 in the direction of the reversing element 5. A terminal end face 48 which extends at right angles to the contact surface 12 or to the surface 15 and also, like the end face 9, at right angles to the longitudinal middle axis 20 delineates the base plate 11 in a direction facing away from the reversing element 5. It is spaced apart from the end face 9 or the lower edge 38 by a base plate length 49 measured parallel to the longitudinal middle axis The centre 22 of the perforation 23 nearest the terminal end face 48 is spaced apart from the latter by an offset 50. The fastening tab 4 has two longitudinal ribs 27 which form reinforcing ribs 17 and extend symmetrically, for example parallel to the longitudinal middle axis 20. As can be seen in Figure 5, said longitudinal ribs 27 have a Ushaped cross section which is open towards the article 14 and has, in each case, a web 51 extending, for example, parallel to the base plate 11 and, in each case, two limbs
S
extending perpendicular to the base plate 11, one of which is preferably integrally -13joined, in particular formed, glued or welded onto the base plate 11. There is no reinforcing rib 17 at the terminal end face 48 in this embodiment.
The reversing element 5 is formed by a web 7 which has a U-shaped contour and is formed from two longitudinal webs 31 extending symmetrically with respect to the longitudinal middle axis 20, in particular parallel to the latter, and a transverse web 32 joining the longitudinal webs 31 in the direction opposite to the fastening tab 4. In this connection, the longitudinal webs 31 form, for example, a continuation of the longitudinal ribs 27 of the fastening tab 4. The web 7, in particular an internal contour 8, and the end face 9, in particular the lower edge 38, form the boundary of a threading opening 10 for a pulling element 6. The internal contours 8 of the longitudinal webs 31 are spaced apart by an opening width 33, measured at right angles to the longitudinal middle axis 20, which approximately equals a plate width 26, measured parallelto the latter, of the base plate 11 which plate width.26 is delineated by mutually facing side faces 53 of the limbs 52 of the longitudinal ribs 27.
Viewed in a longitudinal section, the longitudinal webs 31 have an angular extension.
A first subarea 54 adjacent to the fastening tab 4 has an lower side 36 which faces the article 14 and which extends in an inclined manner angularly from the end face 9 in the direction opposite to the fastening tab 4 and in the direction of a supporting plane 13 of the article 14, the lower side 36 enclosing, with the surface 15 and/or with the contact surface 12, a pitch angle 37 which is greater than 900. The first subarea 54 is delineated by a bend area 35 from which a further subarea 55 of the longitudinal web 31 extends up to the transverse web 32. Said further subarea 55 likewise has an lower side 39 facing the article 14 and extends angularly in a direction opposite to the fastening tab 4 and to the supporting plane 13 of the article 14 or of a plane receiving the lower side 36 of the first subarea 54 in the area projecting in the direction of the further subarea 55, with which area the lower side 39 encloses a pitch angle 40 which is preferably less than 900.
-14- The transverse web 32, and also the longitudinal webs 31, are formed as a hollowprofile curled section 41 which has, for example, a rectangular, square, polygonal cross section and has an contour edge 56, facing the supporting plane 13, which is spaced apart from the supporting plane 13 of the article 14 by a threading height 44 measured at right angles to the supporting plane 13. Said threading height 44 is preferably greater than a thickness 46 of the pulling element 6. This has the result that the web 7, i.e. the subarea 54 adjacent to the fastening tab 4, forms an obtuse pitch angle 37 with the contact surface 12 of the fastening tab 4 and extends up to the bend area from which the transverse web 32 or the subarea 55 of the longitudinal webs 31 or the web 7 extend at an acute pitch angle 40 with respect to the supporting plane 13. In this connection, the element. 1, i.e. the eye ring 3, is formed as an injection moulding, compression moulding or casting made of metal or as a shaped metal part, in particular from a planar blank cut from stainless metal sheet or a copper/iron alloy. It may, however, also be made of plastic.
The jointly described Figures 6 and 7 show a further design variant of an element 1, in particular an eye ring 3, which is made, for example, as a plastic injection moulding.
In this case, the fastening tab 4 has a step 58 spaced apart from the terminal end face 48 in the direction of the reversing element 5 by a distance 57, as a result of which the fastening tab 4 is separated into a part tab 59 and a part tab 60, the part tab 59 having a tab thickness 61 projecting from the supporting plane 13 in the direction opposite to the article 14, which tab thickness 61 spaces a tab surface 62 apart from the contact surface 12 facing the supporting plane 13.
In this connection, the tab thickness 61 is less than the base plate thickness 16 of the base plate 11 of the part tab 60. The tab thickness 61 must be chosen, in particular, so that it is made possible for a needle to penetrate for the purpose of sewing the part tab 59 to the article 14. The part tab 60 again has two longitudinal ribs 27 which are disposed symmetrically around the longitudinal middle axis 20 and which are spaced apart by the plate width 26 extending at right angles to the longitudinal middle axis 0. In this design variant, the reversing element 5 has a V-shaped contour 8, a subarea 54 of the web 7, which subarea 54 is adjacent to the fastening tab 4, in particular the part tab 60, extending in an inclined manner at an obtuse pitch angle 37 in the direction opposite to the fastening tab 4 and in the direction of the supporting plane 13 of the article 14 up to the bend area 35, from where the subarea 55 of the web 7 extends at the pitch angle 40 in the direction opposite to the supporting plane 13 and to the fastening tab 4. The web 7 has, for example, a circular solid cross section.
The jointly described Figures 8 and 9 show an element 1 for closing a slot-type opening, in particular a clamping device 63 for at least one lace-type or ribbon-type pulling element 6 comprising the fastening tab 4, a swivel-bearing fixture 64 disposed on the latter, and a clamping body 65 preferably joined integrally, in particular formed, welded or glued onto the latter, to the fastening tab 4. In this case, the swivel-bearing device 64 serves to receive the reversing element.5.. The. swivel-bearing fixture 64 is formed as a shaped metal part, in particular a bend part, and has, in an area facing the clamping body 65, a bearing casing 66 and,.in an area facing away from the clamping body 65, a rivet tab 67 which has at least one perforation 23 for receiving a fastening means. The bearing casing 66 forms a bearing bore 68 which has a bore diameter 69 measured, for example, at right angles to the contact surface 12. The bearing bore 68 serves to receive two spindles 70 which are directed towards one another and preferably extend at right angles to a longitudinal middle axis 20 of the clamping device 63 and which are integrally joined to the reversing element 5 of, for example, U-shaped design.
In the centre of the spindles 70, a swivel axis 71 extends at right angles to the longitudinal middle axis 20 and parallel to the contact surface 12. The spindles 70 have a spindle diameter 72 which is less than the bore diameter 69 and is approximately equal to a cross-sectional diameter 73 of the reversing element 5. The reversing element 5 is bounded in the direction of the clamping body 65 by an internal surface 74 which has an arch-shaped extension. The clamping body 65 has a front surface 75 which faces the internal surface 74 and which extends, in the present exemplary embodiment, approximately concentrically with respect to the internal surface 74. The internal surface -o 4, -16- 74 delineates a surface radius 76 which is measured from a middle point 77 situated on the longitudinal middle axis 20. The front surface 75 is delineated by a front surface radius 78. The reversing element 5, in particular its spindles 70, are mounted so as to be movable relatively along the longitudinal middle axis 20 in the bearing bore 68, whose bore diameter 69 is greater than the spindle diameter 72. When the spindles make contact with a subarea of the bearing bore 68, which subarea is nearest the clamping body 65, this has the effect that the internal surface 74 is spaced apart from the front surface 75 in the direction opposite to the clamping body 65 by a gap width 79.
The clamping body 65, which is integrally joined, in particular formed, joined or welded, to the fastening tab 4 has, in an end face 80 facing the swivel-bearing fixture 64, a slot-type recess 81 which extends at right angles to the longitudinal middle axis approximately parallel to the contact surface 12. In this connection, the slot-type recess 81 is shaped concavely in the direction of the reversing element 5 and has a recess width 82, measured approximately at right angles to the contact surface 12, which is delineated by two recess edges 83 extending at right angles to the longitudinal middle axis 20 and parallel to the contact surface 12. In each case, there extends from the recess edges 83 a stop surface 84 which extends angularly in the direction of the swivel-bearing fixture 64 and of the contact surface 12 or in a direction opposite to the latter, i.e. in the direction of an upper side 85 of the clamping body 65, which upper side 85 faces away from the contact surface 12. In this connection, the upper side 85 is spaced apart from a tab surface 86 of the fastening tab 4 by a height 87 in the direction opposite to the contact surface 12, the height 87 preferably being greater than the cross-sectional diameter 73 or the spindle diameter 74 of the reversing element In this connection, the tab surface 86 serves to support the rivet tab 67 of the swivelbearing fixture 64 and is spaced apart from the surface 15 of the fastening tab 4 in the ,.3Otdirection of the contact surface 12 by a distance 88. The latter is preferably greater, in RA eno -i .end area 83 of the clamping device 63 facing away from the reversing element -17than a thickness 90 of the rivet tab 67 of the swivel-bearing fixture 64 which, like the distance 88, is measured, for example, approximately at right angles to the contact surface 12.
The reversing element 5 has a swivel radius 91 measured from the swivel axis 71 to the internal surface 74. If the spindles 70 are in a state of contact with a subarea of the bearing bore 68 nearest the clamping body 65, the swivel radius 91 is at least equally as great as a width 92 which spaces the front surface 75 apart, for example, from the swivel axis 71 extending, in the case of a concentric arrangement of the spindles 70, concentrically in the bearing bore 68. The swivelling range of the reversing element 5 from a locking position for the pulling element 6, extending approximately parallel to the contact surface 12, into a release position in which the clamping body is not bounded by the reversing element 5 has a swivel angle which is approximately 1800. The clamping body 65 has, at a side facing away from the swivel-bearing fixture 64, a clamping device 93 which is formed by a groove-shaped depression 94. This is disposed in the front surface 75 so that it projects beyond the latter concavely in the direction of the swivel-bearing fixture 64 and, like the internal surface 74 forms a clamping surface 95 for the pulling element 6. In this connection, the internal surface 74 of the reversing element 5 forming a clamping surface 95 is spaced apart from the clamping surface 95 of the groove-shaped depression 94 by a distance 96 which is measured approximately parallel to the contact surface 12 and which is at least not greater than the thickness 46 of the pulling element 6. In this connection, the distance 96 may be approximately constant over the extension of the front surface 75 or over the extension of the internal surface 74 of the reversing element 5. In the present exemplary embodiment, however, the distance 96 is greatest in the area of the longitudinal middle axis 20 and decreases over the further extension of the internal surface 74.
The clamping body 65 has a width 97, measured at right angles to the longitudinal middle axis 20 of the clamping device 63, which is preferably less than an internal R width 98 of the reversing element 5, measured parallel to the swivel axis 71, which aces apart the internal surface 74 in a direction extending parallel to the swivel axis -18- 71. A further possibility is to form the clamping body 65 from plastic and to replace the swivel-bearing fixture 64 formed by the integral shaped metal part by a bearing bore 68 which is disposed in the clamping body 65 and extends concentrically around the swivel axis 71 and in which the reversing element 5 is then mounted with spindles 70 facing one another and extending linearly. In this case, the bearing bore 68 would have the recess 81 which would project from the bearing bore 68 in the direction of the reversing element 5. Finally, it is also possible to form the clamping body jointly with the fastening tab 4 as an integral injection moulding, compression moulding or casting made of metal and/or plastic.
The mode of operation of the clamping device 63 is explained as follows. For the purpose of threading the pulling element 6 through the reversing element 5, the latter is swivelled into a release position remote from the clamping body 65. Once the pulling element 6 has been threaded through, it is swivelled:around the swivel axis 71 in the direction of the clamping body 65 or of the clamping device 93. Once the reversing element 5 reaches the clamping body 65 in the area of the front surface 75, the distance between the front surface 75 and the internal surface 74 is smaller than the thickness 46 of the pulling element 6. In order to facilitate the final swivelling of the reversing element 5 into the locking position, the clamping body 65 has the recess 81.
This achieves the result that the swivelling fixture 64 can be moved in the direction of the clamping body 65 as a result of which the distance between the internal surface 74 and the front surface 75 is increased so that it is equal under these circumstances to approximately the thickness 46 of the pulling element 6. By pressing a curved curvature surface 99 delineating the swivel-bearing fixture 64 in the direction of the clamping body 65 against the stop surfaces 84 extending at an angle, a force is exerted on the latter which resolves into a vertical component extending approximately at right angles to the contact surface 12 and a horizontal component extending parallel to the latter. The vertical component of the forces acting at right angles on the stop surfaces 84 results in a relative movement in the direction opposite to the contact surface 12 in particular in a spring web 100 which is delineated by the upper side 85 and the stop ace 84 of the clamping body 65 and also by an internal surface 101 facing away -19from the upper side 85 and extending approximately parallel to the latter, which results in a widening of the recess width 82 of the recess 81 and, consequently, in a relative movement of the swivel-bearing device 64, in particular of the bearing casing 66, by elastic deformation of the latter in the direction of the clamping body 65 and, consequently, in a widening of the distance between the front surface 75 and the internal surface 74 of the reversing element 5. As a result, the reversing element 5 with the pulling element 6 fed through can be swivelled, without compressing the latter too much, into the locking position, the spring web 100 moving back in the direction of the contact surface 12 and the original recess width 82 of the recess 81 being established. As a result, the distance 96 between the clamping surface 95 of the depression 94 and the clamping surface 95 formed by the internal surface 74 of the reversing element 5 is adjusted so that it is at least not greater than the thickness.46 of the pulling element 6, as a result of which the latter is clamped in the clamping device 93.
It may further be mentioned that the reversing element 5 may also have a V-shaped contour. In addition, any design of a contour edge 102 forming the outer boundary of the fastening tab 4 is possible. It is also possible to provide a plurality of perforations 23 and to design them not only with a circular contour, but in any desired shape.
For the purpose of fastening the swivel-bearing fixture 64 to the fastening tab 4, a distance 103 which is measured approximately parallel to the contact surface 12 and a recess edge 83 which is spaced apart from an end face 104 extending approximately at right angles to the contact surface 12 and joining the surface 15 of the fastening tab 4 to the tab surface 86 is no greater than a distance 105 of an internal surface 106 extending parallel to the end face 104 from a tangent line which extends parallel to the swivel axis 71 at the curvature surface 99 of the bearing casing 66 parallel to the swivel axis 71 and which is in contact, for example, with the recess edge 83.
This achieves the result that the swivel-bearing fixture 64 can be clamped in a groove 107 of the fastening tab 4, which groove 107 is bounded by the tab surface 86 and the d face 104 and a spontaneous removal of the swivel-bearing fixture 64 from the fastening tab 4 is prevented even without fastening means 24. The contact surface 12, shown as curved, is designed so that it fits the supporting plane 13 of the article 14 and can also, in particular, be of planar design.
The jointly described Figures 10 and 11 show an element 1, in particular a clamping device 63, which is designed as already described. In addition, the clamping device 63, in particular the clamping body 65, has a notch 108 which is disposed in the front surface 75. In this case, the notch 108 is designed so that it has a surface line 109 at its surface area nearest the supporting plane 13 of the article 14, which surface line 109 lies in a longitudinal middle plane 110 extending at right angles to the supporting plane 13 in the longitudinal axis 20 and extends in an inclined manner from the surface of the clamping body 65 at an angle 111 with respect to the supporting plane 13 and oppositely to the swivel-bearing fixture 64. In:this connection, the angle 111 is to 850, preferably 450 The notch 108 has a width 112 measured at right angles to the longitudinal middle axis 20 and a notch length 113 measured from the front surface in the direction of the swivel-bearing fixture 64. In the area of the recess 94, the notch 108 forms an edge of cut 114 which is spaced apart from the internal surface 74 of the reversing element 5 by a width 115, which is greater than a distance 116 of the front surface 75 from the internal surface 74. This makes it possible that even pulling elements 6 having a circular cross section which have no elastic deformation capacity per se can easily be clamped without greater wear of the reversing element 5 or of the clamping body 65 arising and, in particular, the force expended on clamping pulling elements 6 having preferably circular cross sections is reduced. Such a design of the clamping body 65 with the notch 108 is not, however, an obstacle to the use of a ribbon-type pulling element 6.
It is furthermore possible to design the clamping device 63, in particular the contact surface 12 of the fastening tab 4, with a rotation lock 117. This comprises bladeshaped strips 118 which project beyond the contact surface 12 in the direction of the W2& supporting plane 13 and are disposed symmetrically around the perforation 23. Once 1)4 -21 the clamping device 63 is joined to the article 14 by a fastening means 24, the strips 118 are pressed into the supporting plane 13 of the article 14, as a result of which rotation of the clamping device 63 on the article 14 is avoided. Such a rotation lock 117 can also be provided in the case of the eye ring according to the invention.
Figure 12 described finally shows a subarea of an article 14, in particular a shoe 119, which has a slot-type opening 2 in the instep area. Shown along the slot-type opening 2 is a closure system for closing the opening 2 with at least one lace-type or ribbontype pulling element 6, which closure system has a plurality of eye rings 3, spaced apart from one another, which do not, however, have to be limited to the design of the eye ring 3 according to the invention. In addition, one or more clamping devices 63 disposed along the opening 2 are provided which have a fastening tab 4 and a swivelbearing fixture 64 having a swivel axis 71 for a swivellable reversing element 5 and a clamping body 65 which, in the case of a position of the reversing element 5 situated approximately parallel to the supporting plane 13, are encompassed in places by the latter. As a result it is now possible to form the tension of the pulling element 6, for example, in a forefoot area 120 differently from the tension of the pulling element 6 in a shinbone area 121 of the opening 2 and to lock the entire closure system in an area adjacent to a shoe opening 122.
As already mentioned above in the description, various fastening means can be possible for mounting the element 1 on an article 14.
Instead of the fastening means 24 shown, for example, in Figures 1 and 2 involving rivets with a relatively small head, it is also possible to use rivets with a greater head diameter at least in the area of the element 1 or to deform said rivet head during riveting so that it fits without a seam to the external contour of the element 1 and also covers an optionally more deeply set central area of the fastening tab 4. In the case of the design variants according to the further exemplary embodiments, it is also possible to use rivets or fastening means 24 having, in the area resting on the outer surface of I) the element 1, a greater diameter or cover plates covering a greater area. Thus, it is Lu rt 22 also possible inter alia, to design fastening means 24 preferably with a head having smaller dimensions and to provide, under certain circumstances, a suitably matched interlayer plate which covers the remaining area as an upper lining part.
Finally, it is pointed out that individual design details described in Figures 1 to 12 can be combined in any desired manner with one another and may represent independent inventions. In addition, it is pointed out that the figures are shown in some cases not to scale for the purpose of better visibility of the design details.
