Definitions
- the invention relates to a safety shoe with a toe cap, which has a shape substantially adapted to the tip of a shoe and facing the sole has an inwardly directed flanged edge, in which the flanged edge of the toe cap is inserted into a groove arranged in the vertical end face of the sole tip and by means of the Upper part is held therein, the upper groove wall being set back from the lower groove wall by at least the thickness of the toe protection cap and the upper part being connected to the lower groove wall.
- Such a safety shoe is known from DE-A-23 40 146 and has the advantage that the toe cap, which mostly consists of metal, does not have to be fastened to the sole by means of separate fastening parts.
- the flanged edge inserted into the groove of the sole holds the toe cap in the direction perpendicular to the tread of the sole and the upper part which is then connected to the sole then fixes the toe cap permanently and captively to the sole.
- the sole is composed of a lower part and an upper part.
- a shoulder is formed on the upper edge of the lower part, which is surmounted by the upper part, so that the groove for the flanged edge of the toe cap is formed.
- This composite sole makes the production of the safety shoe more expensive.
- Another disadvantage of this known safety shoe is that the toe cap has a play in the groove even after the upper part has been attached and is not stuck.
- the toe cap must also be held when attaching the upper to the sole, which complicates the manufacture of the safety shoe, at least at the beginning of the attachment of the upper.
- the groove is introduced into a one-piece solid sole, the width and / or the depth of the groove having (a) smaller dimension (s) than the thickness and / or the width of the Flanged edge and that the flanged edge of the toe cap is pressed into the solid sole up to the stop of the toe cap on the end face of the upper groove wall and is thereby held in the groove as nailed.
- the groove can be inserted into the commercially available solid sole during manufacture, e.g. in the form, provided (e.g. plastic sole) or only the groove needs to be milled (wooden sole), whereby the dimensioning must be observed.
- the easiest way to ensure this is that the groove with the recessed upper groove wall and the shoulder on the lower groove wall with an appropriately designed shape or milling cutter is introduced into the vertical end face of the solid sole in one operation.
- the toe cap can then be pressed into the solid sole in the manner of a nail, the groove walls causing the flange edge to jam and / or the groove base being deformed by the flange edge.
- the toe cap is pressed in as far as it will go on the front surface of the upper groove wall, then the toe cap is adequately held on the solid sole and the toe cap no longer unintentionally loosens during further operations, in particular when attaching the upper part to the solid sole.
- the work steps in the manufacture of the safety shoe are much easier to carry out than the known safety shoe, which is reflected in reduced manufacturing costs.
- the lower groove wall of the toe protection cap has an end shoulder, the vertical section of which is flush with the outer surface of the toe protection cap, then the upper part can be turned over without the lower edge, directly with the vertical section of the shoulder on the lower groove wall be connected, which also has a cost-reducing effect on the manufacturing process.
- the pressing of the flanged edge into the groove base of the groove can be facilitated in one embodiment in that the flanged edge of the toe cap ends in a point.
- the flanged edge is sawtooth-shaped, the tooth tips being arranged at an angle such that they penetrate into the groove base of the solid sole in the longitudinal direction.
- the vertical dimension of the upper groove wall corresponds approximately to the thickness of a preferably anatomically shaped insole.
- the upper groove wall has sufficient strength to withstand the stresses that occur when the toe cap penetrates the groove in the solid sole.
- the vertical section of the shoulder on the lower groove wall is about 10 mm wide.
- a clean end of the safety shoe in the area of the sole tip is achieved in that the lower groove wall outside of the heel is flush with the outer surface of the upper part fastened to the vertical section of the lower groove wall.
- the groove in the solid sole is extended in the direction of the middle part of the solid sole and accommodates a midfoot protective cap provided with a flanged edge before the toe protective cap is fixed in the groove.
- a further embodiment provides that the vertical section of the heel extends beyond the groove at least over the entire fastening surface of the upper part.
- a one-piece wooden sole 10 is used as the sole, which is anatomically adapted to the shape of the foot on the top 11 and can also be provided with non-slip coverings or the like in the area of the tread.
- the toe cap 20 is also commercially available and defines the receiving space for the toes.
- the lower edge of the toe protection cap 20, which is preferably made of metal or a similarly strong material, is angled inwards and designed as a flanged edge 21.
- the shape of the wooden sole 10 and the toe cap 20 are matched to one another. In the area of the sole tip, the groove 12 is milled into the vertical outer surface of the wooden sole 10.
- the upper groove wall 13 and the lower groove wall 19 are divided.
- the width and / or the depth of the groove 12 is now deliberately chosen to be smaller than the thickness and / or the width of the flanged edge 21 of the toe protection cap 20.
- the upper groove wall 13 is removed at the end by the thickness of the toe protection cap 20, as the end face 14 shows.
- the toe cap 20 is inserted with the flanged edge 21 into the groove 12 and pressed into the wooden sole 10 until the toe cap 20 abuts the end face 14 of the upper groove wall 13.
- the flanged edge 21 can be clamped between the groove walls 13 and 19 and / or the flanged edge 21 can be pressed into the groove base, this depends on the dimensioning of the width and / or depth of the groove 12.
- the toe cap 20 fastened in this way to the wooden sole 10 is already clearly held to it and this without additional fastening parts.
- the toe cap 20 therefore no longer needs to be held in place, which considerably simplifies and simplifies the further operations compared to the operations in known safety shoes.
- the lower groove wall 19 has the shoulder 16 facing the end of the groove 12, the vertical section 17 of which is flush with the outer surface of the toe cap 20 pressed into the groove 12.
- the upper part 22 can therefore be connected directly to the vertical section 17 of the shoulder 16 without folding the lower edge, as the fastening parts 23 indicate.
- the end face 18 of the lower groove wall 19 which is not occupied by the upper part 22 is flush with the outer surface of the upper part 22 fastened to the wooden sole 10.
- the groove 12 can have a lateral extension 23 directed towards the central part of the wooden sole 10, which can accommodate a metatarsal protective cap with a corresponding flanged edge before the toe protective cap 20 is pressed into the groove 12 of the wooden sole 10.
- the shoulder 16 with the vertical section 17 extends beyond the groove 12 and forms a stepped fastening surface in the entire area of the upper part 22.
- the type of upper part 22 can be chosen freely without impairing the attachment of the toe cap 20 if only the groove 12 with the groove walls 13 and 19 is designed accordingly.
Abstract
Description
Die Erfindung betrifft einen Sicherheitsschuh mit einer Zehenschutzkappe, die eine im wesentlichen der Spitze eines Schuhes angepaßte Form aufweist und der Sohle zugekehrt einen einwärts gerichteten Bördelrand aufweist, bei dem der Bördelrand der Zehenschutzkappe in eine in der vertikalen Abschlußfläche der Sohlenspitze angeordnete Nut eingeführt und mittels des Oberteils darin gehalten ist, wobei die obere Nutwand gegenüber der unteren Nutwand um mindestens die Dicke der Zehenschutzkappe zurückgesetzt und das Oberteil mit der unteren Nutwand verbunden ist.The invention relates to a safety shoe with a toe cap, which has a shape substantially adapted to the tip of a shoe and facing the sole has an inwardly directed flanged edge, in which the flanged edge of the toe cap is inserted into a groove arranged in the vertical end face of the sole tip and by means of the Upper part is held therein, the upper groove wall being set back from the lower groove wall by at least the thickness of the toe protection cap and the upper part being connected to the lower groove wall.
Ein derartiger Sicherheitsschuh ist durch die DE-A- 23 40 146 bekannt und hat den Vorteil, daß die Zehenschutzkappe, die meistens aus Metall besteht, nicht mittels getrennter Befestigungsteile an der Sohle befestigt werden muß. Der in die Nut der Sohle eingeführte Bördelrand hält die Zehenschutzkappe in Richtung senkrecht zur Lauffläche der Sohle fest und das anschließend mit der Sohle verbundene Oberteil legt die Zehenschutzkappe dann endgültig unverlierbar an der Sohle fest.Such a safety shoe is known from DE-A-23 40 146 and has the advantage that the toe cap, which mostly consists of metal, does not have to be fastened to the sole by means of separate fastening parts. The flanged edge inserted into the groove of the sole holds the toe cap in the direction perpendicular to the tread of the sole and the upper part which is then connected to the sole then fixes the toe cap permanently and captively to the sole.
Bei diesem bekannten Sicherheitsschuh wird die Sohle aus einem Unterteil und einem Oberteil zusammengesetzt. Dabei ist an der oberen Kante des Unterteils ein Absatz gebildet, der von dem Oberteil überragt wird, so daß die Nut für den Bördelrand der Zehenschutzkappe gebildet wird. Diese zusammengesetzte Sohle verteuert die Herstellung des Sicherheitsschuhes. Ein weiterer Nachteil dieses bekannten Sicherheitsschuhes liegt darin, daß die Zehenschutzkappe selbst nach dem Anbringen des Oberteils in der Nut ein Spiel aufweist und nicht festsitzt. Außerdem muß beim Anbringen des Oberteils an der Sohle die Zehenschutzkappe zusätzlich gehalten werden, was die Herstellung des Sicherheitsschuhes zumindest zu Beginn der Anbringung des Oberteils erschwert.In this known safety shoe, the sole is composed of a lower part and an upper part. A shoulder is formed on the upper edge of the lower part, which is surmounted by the upper part, so that the groove for the flanged edge of the toe cap is formed. This composite sole makes the production of the safety shoe more expensive. Another disadvantage of this known safety shoe is that the toe cap has a play in the groove even after the upper part has been attached and is not stuck. In addition, the toe cap must also be held when attaching the upper to the sole, which complicates the manufacture of the safety shoe, at least at the beginning of the attachment of the upper.
Es ist Aufgabe der Erfindung, einen Sicherheitsschuh der eingangs erwähnten Art so zu verbessern, daß die Metallkappe ohne zusätzliche Befestigungsteile schon vor dem Anbringen des Oberteils an der Sohle so an der Sohle festgelegt werden kann, daß sie sicher kein Spiel mehr aufweist und beim Anbringen des Oberteils an der Sohle nicht mehr gehalten werden muß, um so die Herstellung des Sicherheitsschuhes gegenüber der bisher bekannten mehrstufigen Fabrikationsmethode wesentlich zu vereinfachen.It is an object of the invention to improve a safety shoe of the type mentioned above so that the metal toe can be fixed to the sole without additional fastening parts before the upper part is attached to the sole in such a way that it no longer has any play and when the Upper part no longer has to be held on the sole so as to significantly simplify the manufacture of the safety shoe compared to the previously known multi-stage manufacturing method.
Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß die Nut in eine einstückige Massivsohle eingebracht ist, wobei die Breite und/oder die Tiefe der Nut (eine) kleinere Abmessung(en) aufweist (aufweisen) als die Dicke und/oder die Breite des Bördelrandes und daß der Bördelrand der Zehenschutzkappe bis zum Anschlag der Zehenschutzkappe an der Stirnfläche der oberen Nutwand in die Massivsohle eingedrückt und dadurch in der Nut wie genagelt festgehalten ist.This object is achieved according to the invention in that the groove is introduced into a one-piece solid sole, the width and / or the depth of the groove having (a) smaller dimension (s) than the thickness and / or the width of the Flanged edge and that the flanged edge of the toe cap is pressed into the solid sole up to the stop of the toe cap on the end face of the upper groove wall and is thereby held in the groove as nailed.
In die handelsübliche Massivsohle kann die Nut schon bei der Herstellung, z.B. in der Form, vorgesehen sein (z.B. Kunststoffsohle) oder es braucht nur die Nut eingefräst zu werden (Holzsohle), wobei auf die Bemessung geachtet werden muß. Dies läßt sich am einfachsten dadurch sicherstellen, daß die Nut mit der zurückgesetzten oberen Nutwand und dem Absatz an der unteren Nutwand mit einer entsprechend ausgebildeten Form oder ausgebildeten Fräser in einem Arbeitsgang in die vertikale Abschlußfläche der Massivsohle eingebracht ist. Die Zehenschutzkappe kann dann in die Massivsohle nach Art eines Nagels eingedrückt werden, wobei die Nutwände eine Verklemmung des Bördelrandes bringen und/oder der Nutgrund durch den Bördelrand verformt wird. Ist die Zehenschutzkappe bis zum Anschlag an der Stirnfläche der oberen Nutwand eingedrückt, dann ist ein ausreichender Halt der Zehenschutzkappe an der Massivsohle erreicht und die Zehenschutzkappe löst sich bei weiteren Arbeitsgängen, insbesondere beim Anbringen des Oberteils an der Massivsohle, nicht mehr unbeabsichtigt. Die Arbeitsgänge beim Herstellen des Sicherheitsschuhes sind gegenüber dem bekannten Sicherheitsschuh wesentlich leichter durchzuführen, was sich in reduzierten Herstellkosten niederschlägt.The groove can be inserted into the commercially available solid sole during manufacture, e.g. in the form, provided (e.g. plastic sole) or only the groove needs to be milled (wooden sole), whereby the dimensioning must be observed. The easiest way to ensure this is that the groove with the recessed upper groove wall and the shoulder on the lower groove wall with an appropriately designed shape or milling cutter is introduced into the vertical end face of the solid sole in one operation. The toe cap can then be pressed into the solid sole in the manner of a nail, the groove walls causing the flange edge to jam and / or the groove base being deformed by the flange edge. If the toe cap is pressed in as far as it will go on the front surface of the upper groove wall, then the toe cap is adequately held on the solid sole and the toe cap no longer unintentionally loosens during further operations, in particular when attaching the upper part to the solid sole. The work steps in the manufacture of the safety shoe are much easier to carry out than the known safety shoe, which is reflected in reduced manufacturing costs.
Ist nach einer Ausgestaltung vorgesehen, daß die untere Nutwand der Zehenschutzkappe zugekehrt einen stirnseitigen Absatz aufweist, dessen vertikaler Abschnitt bündig mit der Außenfläche der Zehenschutzkappe abschließt, dann kann das Oberteil ohne den unteren Rand umzuschlagen, direkt mit dem vertikalen Abschnitt des Absatzes an der unteren Nutwand verbunden werden, was sich ebenfalls kostenreduzierend auf den Herstellvorgang auswirkt.If it is provided according to an embodiment that the lower groove wall of the toe protection cap has an end shoulder, the vertical section of which is flush with the outer surface of the toe protection cap, then the upper part can be turned over without the lower edge, directly with the vertical section of the shoulder on the lower groove wall be connected, which also has a cost-reducing effect on the manufacturing process.
Das Eindrücken des Bördelrandes in den Nutgrund der Nut läßt sich nach einer Ausgestaltung dadurch erleichtern, daß der Bördelrand der Zehenschutzkappe spitz ausläuft.The pressing of the flanged edge into the groove base of the groove can be facilitated in one embodiment in that the flanged edge of the toe cap ends in a point.
Denselben Zweck erfüllt eine Ausgestaltung, die dadurch gekennzeichnet ist, daß der Bördelrand sägezahnartig ausgebildet ist, wobei die Zahnspitzen im Winkel so angeordnet sind, daß sie in Längsrichtung in den Nutgrund der Massivsohle eindringen.The same purpose is fulfilled by an embodiment which is characterized in that the flanged edge is sawtooth-shaped, the tooth tips being arranged at an angle such that they penetrate into the groove base of the solid sole in the longitudinal direction.
Damit der von der Zehenschutzkappe umschlossene Raum auch optimal zur Aufnahme der Zehen ausgenützt wird, sieht eine Ausgestaltung vor, daß die vertikale Abmessung der oberen Nutwand etwa der Dicke einer vorzugsweise anatomisch geformten Brandsohle entspricht. Die obere Nutwand hat eine ausreichende Festigkeit, damit sie beim Eindringen der Zehenschutzkappe in die Nut der Massivsohle den auftretenden Spannungen standhält.In order that the space enclosed by the toe protection cap is also optimally used for receiving the toes, one embodiment provides that the vertical dimension of the upper groove wall corresponds approximately to the thickness of a preferably anatomically shaped insole. The upper groove wall has sufficient strength to withstand the stresses that occur when the toe cap penetrates the groove in the solid sole.
Um eine ausreichend große Befestigungsfläche für das Oberteil an der Massivsohle zu erhalten, ist weiterhin vorgesehen, daß der vertikale Abschnitt des Absatzes an der unteren Nutwand etwa 10 mm breit ist.In order to obtain a sufficiently large fastening surface for the upper part on the solid sole, it is further provided that the vertical section of the shoulder on the lower groove wall is about 10 mm wide.
Ein sauberer Abschluß des Sicherheitsschuhes im Bereich der Sohlenspitze wird nach einer Ausgestaltung dadurch erreicht, daß die untere Nutwand außerhalb des Absatzes bündig mit der Außenfläche des an dem vertikalen Abschnitt der unteren Nutwand befestigten Oberteils abschließt.According to one embodiment, a clean end of the safety shoe in the area of the sole tip is achieved in that the lower groove wall outside of the heel is flush with the outer surface of the upper part fastened to the vertical section of the lower groove wall.
Soll der Sicherheitsschuh auch im Bereich des Mittelfußes erhöhte Stabilität erhalten, dann wird nach einer Ausgestaltung vorgesehen, daß die Nut in der Massivsohle in Richtung zum Mittelteil der Massivsohle verlängert ist und eine mit Bördelrand versehene Mittelfußschutzkappe aufnimmt, bevor die Zehenschutzkappe in der Nut festgelegt wird.If the safety shoe is also to be given increased stability in the area of the midfoot, then according to one embodiment it is provided that the groove in the solid sole is extended in the direction of the middle part of the solid sole and accommodates a midfoot protective cap provided with a flanged edge before the toe protective cap is fixed in the groove.
Damit das gesamte Oberteil vertieft in der Außenfläche der Massivsohle befestigt werden kann, sieht eine weitere Ausgestaltung vor, daß sich der senkrechte Abschnitt des Absatzes über die Nut hinaus zumindest über die gesamte Befestigungsfläche des Oberteils erstreckt.In order that the entire upper part can be deepened in the outer surface of the solid sole, a further embodiment provides that the vertical section of the heel extends beyond the groove at least over the entire fastening surface of the upper part.
Die Erfindung wird anhand eines im Schnitt durch die Schuhspitze dargestellten Ausführungsbeispiels näher erläutert.The invention is explained in more detail using an exemplary embodiment shown in section through the toe of the shoe.
Als Sohle wird eine einstückige Holzsohle 10 verwendet, die auf der Oberseite 11 anatomisch an die Fußform angepaßt ist und im Bereich der Lauffläche auch noch mit rutschsicheren Belägen oder dgl. versehen sein kann. Die Zehenschutzkappe 20 ist ebenfalls handelsüblich und bestimmt den Aufnahmeraum für die Zehen. Der untere Rand der Zehenschutzkappe 20, die vorzugsweise aus Metall oder einem ähnlich festen Material besteht, ist nach innen abgewinkelt und als Bördelrand 21 ausgebildet. Die Form der Holzsohle 10 und der Zehenschutzkappe 20 sind aufeinander abgestimmt. Im Bereich der Sohlenspitze ist die Nut 12 in die vertikale Außenfläche der Holzsohle 10 eingefräst. Dabei wird die obere Nutwand 13 und die untere Nutwand 19 abgeteilt. Die Breite und/oder die Tiefe der Nut 12 wird nun bewußt kleiner gewählt als die Dicke und/oder die Breite des Bördelrandes 21 der Zehenschutzkappe 20. Außerdem wird beim Einbringen der Nut 12 die obere Nutwand 13 stirnseitig um die Dicke der Zehenschutzkappe 20 abgetragen, wie die Stirnfläche 14 erkennen läßt. Die Zehenschutzkappe 20 wird mit dem Bördelrand 21 in die Nut 12 eingeführt und so weit in die Holzsohle 10 eingedrückt, bis die Zehenschutzkappe 20 an der Stirnfläche 14 der oberen Nutwand 13 anstößt. Dabei kann der Bördelrand 21 zwischen den Nutwänden 13 und 19 verklemmt und/oder der Bördelrand 21 in den Nutgrund eingedrückt werden, dies hängt von der Bemessung der Breite und/oder Tiefe der Nut 12 ab. Auf alle Fälle wird die so an der Holzsohle 10 befestigte Zehenschutzkappe 20 schon eindeutig daran gehalten und dies ohne zusätzliche Befestigungsteile. Beim Anbringen des Oberteils 22 braucht daher die Zehenschutzkappe 20 nicht mehr festgehalten zu werden, was die weiteren Arbeitsgänge gegenüber den Arbeitsgängen bei bekannten Sicherheitsschuhen wesentlich vereinfacht und erleichtert.A one-piece
Die untere Nutwand 19 trägt stirnseitig der Nut 12 zugekehrt den Absatz 16, dessen vertikaler Abschnitt 17 bündig mit der Außenfläche der in die Nut 12 eingedrückten Zehenschutzkappe 20 abschließt. Das Oberteil 22 kann daher ohne Abkanten des unteren Randes direkt mit dem vertikalen Abschnitt 17 des Absatzes 16 verbunden werden, wie die Befestigungsteile 23 andeuten. Die nicht durch das Oberteil 22 belegte Stirnfläche 18 der unteren Nutwand 19 schließt bündig mit der Außenfläche des an der Holzsohle 10 befestigten Oberteils 22 ab.The
Wie gestrichelt angedeutet, kann die Nut 12 eine zum Mittelteil der Holzsohle 10 hin gerichtete seitliche Verlängerung 23 aufweisen, die eine Mittelfußschutzkappe mit entsprechendem Bördelrand aufnehmen kann, bevor die Zehenschutzkappe 20 in die Nut 12 der Holzsohle 10 eingedrückt wird.As indicated by dashed lines, the
Der Absatz 16 mit dem vertikalen Abschnitt 17 erstreckt sich über die Nut 12 hinaus fort und bildet im gesamten Bereich des Oberteils 22 eine abgesetzte Befestigungsfläche. Die Art des Oberteils 22 kann frei gewählt werden, ohne die Befestigung der Zehenschutzkappe 20 zu beeinträchtigen, wenn nur die Nut 12 mit den Nutwänden 13 und 19 entsprechend ausgelegt ist.The
