Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to a first tension member, a tension lever that is pivotable across the longitudinal direction of the tension member and is secured to the first flap, and a longitudinal direction of the tension member. A second tension member that is connectable to the first tension member at one of a plurality of positions parallel to each other, the second tension member being a second flap different from the first flap. It is fixed, fixing to each flap is done via an eccentric,
The present invention relates to a shoe fastener, particularly a ski shoe fastener, in which a support shaft of an eccentric can be displaced in a longitudinal direction and a lateral direction of a tension member.

Fasteners of the type mentioned at the beginning are used, for example, for the locking of ski boots, in which the locking flap of the shoe is fastened to another flap. In the area of the instep and the instep, the fastening force is generally applied transversely to the longitudinal axis of the shoe, i.e. in the circumferential direction of the cross-sectional profile, so that it is possible to adapt relatively accurately to the respective foot. . In order to apply an appropriate tension by such a circumferential force that crosses the longitudinal direction of the shoe, a fastener having a relatively stable structure is usually required, and the fixed part of the tension member and the tension member itself are exposed to high force. Be done. When plastic is used as the material of the outer shell of the flaps connected to each other and the material of the tension lever and the tension member, a heavy load is applied to each fulcrum or fixed point. Particularly at low temperatures, the plastics tend to become brittle, which can lead to the release of the catch for securing the entrainment lever or the tension member or the tearing of the area of the pivot point of the tension member.

A fastener for skis or hiking shoes, in which a tension bend is adjustably arranged via an intermediate piece in a holder fixed to a locking flap, has already been found in Austrian patent 304306. When the shoe is locked, a tension lever with a notch, which is arranged on another locking flap, engages the tension bend.

Fasteners of the type mentioned at the outset are basically known. Ladder hook plates are known for connecting the interacting tensioning members in different juxtaposed positions.
The hook plate described above makes it possible to fix the fasteners at a plurality of positions that are formed so as to be offset from each other by at least the necessary thickness of the teeth of the hook plate in consideration of the required stability. . As a result, the fastening force of the fastener can only be adjusted stepwise and not continuously. It is known to connect the tension member and the tension lever via an internal thread in order to enable connection adjustment of the fastening force in the above-mentioned fastener. Twisting of this type of tensioning member adjusts the effective length to provide some fine adjustment within the spacing of adjacent hooks. However, even with such a structure, due to the curved outer contour of the shoe, in order to securely engage the hook plate with a new tension member,
It is necessary to twist 360 °. Since the above 360 ° adjustment corresponds to the change in the length of one round of the screw thread, continuous fine adjustment is not possible even with this structure. Furthermore, since the tension member can rotate relative to the tension lever, automatic twisting occurs at the open position of the fastener, which makes locking operation of the fastener difficult. This is because it is necessary to newly obtain an accurate position for inserting the tension member into the hook plate of the second tension member. Usually, a flexible strip or a wire bending piece is used as the tension member, but in such a case, a relatively wide member was required in consideration of the required fastening force.

Thus, the present invention allows for easy continuous adjustment of the effective locking length, while at the same time providing a stable mutual connection of the two locking flaps under small dimensions, in particular the small longitudinal dimension of the shoe. The purpose is to improve the types of fasteners mentioned at the beginning. Further, the present invention avoids an excessive burden on the fulcrum of the tension member or the tension lever of this kind, and even if all the members of the fastener are made of plastic, the fastener can be attached without increasing the risk of the fulcrum coming off. On the other hand, it is intended to ensure that the individual members can rotate to some extent. To solve this problem, the fastener according to the present invention is roughly as follows.
That is, the eccentric is composed of a toothed plate, to which a support shaft of a tension member or a tension lever is arranged, and the toothed plate is attached to the flap via a fastening member having a shoe penetrating the toothed plate, which is different from the support shaft. It can be tightened to. The eccentric is composed of a toothed plate, on which a support shaft of a tension member or a tension lever is arranged, and the toothed plate is fastened to the flap concerned via a tightening member having a shaft that penetrates the toothed plate and is different from the above-mentioned support shaft. The possibility of changing the effective length of one of the tension members by means of relative twisting is possible, whereby the above-mentioned changes are possible steplessly by means of this type of eccentric.

Each of the tooth profile can be securely held in a desired position by being pressed against the locking flap, and twisted around the axis of the tightening member, so that the tension lever or the tension member is pivotally supported around the tooth profile. Since the pulling member or the tightening member can be displaced in the longitudinal direction, an eccentric action occurs. However, this remarkably large perimeter means that the supporting force is better absorbed at the same time, so that even if the hook plate is made of plastic or the tension member or part of the tension lever is made of plastic, the risk of excessive burden is greatly increased. Will be reduced. The pressing of the toothed plate against the underlying locking flap is in principle carried out by the engagement of the screw with an internal thread associated with the locking flap. However, according to a preferred improvement of the fastener according to the present invention, the fastening member of the tooth profile is structured so as to be pivotally attached to the fastening member and can be moved up and down by a lever supported on the tooth profile. Thus, rotation of the eccentric about the axis of the fastening member is facilitated or prevented by raising and lowering the fastening member.

The structure according to the invention is particularly adapted to fasteners made exclusively of plastics, with the respective pivots of the clamping members in contact with the support part and the pivots of the first tensioning member in contact with the tension lever and, for example, the hook plate. Only the rod-shaped locking member for inserting into and attaching to should be made of metal. In order to ensure a high degree of stability with the above plastics under small dimensions, the first tensioning member connected to the clamping lever is preferably constructed of a generally rigid member with a curved cross section. The above-mentioned tensile member having a curved cross section can absorb a high tensile member with a small size,
In this way, in order to better adapt to the outer contour of the shoe under a rigid structure, a structure which is also curved when viewed transversely to the direction of tension can be provided. Double curvature provides a high degree of stability and tensile strength with extremely small dimensions.

As described above, the second tension member connectable to the first tension member for coarse adjustment of the fastening force is formed as a hook plate having a plurality of hooks arranged in the longitudinal direction of the second tension member. And In order to ensure an accurate adaptation of the tensioning member to each locking position without preventing the tensioning lever or the fixing point of the tensioning member from pivoting to some extent with the tensioning member having a curved cross-section in the above structure, Member is second
Has an arcuate end on the projection to the tensioning member and the second tensioning member has a stop for the first tensioning member corresponding to the arcuate shape at the position of the hook plate adjacent to the eccentric. It is preferable to configure as follows. In the above structure, the two tension members are set very short in the locking position, so that the fastening force is maximal and a generally closed outer diameter profile can be obtained. This contour provides a reduced risk of injury. In this case the eccentric interacts with the hook plate,
A structure with a curved cross-section outside the area with the hooks makes it possible to reduce the risk of further injury, which in turn results in a particularly beautiful contour.

The fastener according to the invention for shoes, in particular for skis, will now be described in more detail on the basis of an embodiment shown schematically in the drawings. Figure 1 of the drawings

It is a sectional view by a line. FIG. 3 is an exploded view of the eccentric and the fastening member of the fastener according to the embodiment according to FIGS. 1 and 2, and FIGS. 4 and 5 for fixing the eccentric and the eccentric in a position separated from the flap or connected to the flap. 9 shows a modified embodiment of the tightening member of FIG.

The fastener 1 shown in FIGS. 1 and 2 comprises a tension lever 3 fixed to the first flap of a ski boot. The tension lever 3 is pivotally mounted on a clasp or bearing 6, which is fixed to the flap 2 by means of, for example, rivets or threaded joints 5, so that it can pivot about an axis 4. The tension lever 3 allows the tension member 8 to pivot about another axis 7.
It is fixed to. The tension member 8 comprises a substantially rigid curved member which at the opposite end of the pivot 7 has a pin or shaft 9 for interacting with a second tension member 10.
The locking member is made of. Sawtooth 11
A second tensioning member 10 formed as a hook plate with a hook is retracted into the first tensioning member or covered by the first tensioning member due to the interaction of the saw teeth 11 with the pin 9 depending on the fixed position. In the area, the first tension member 8 is formed in the shape of a hollow or tunnel. The second tension member 10 is the first
Is fixed to a flap 12 different from the flap 2 of FIG. 1 and is provided with an eccentric 13 made of a tooth profile plate for finely adjusting the total effective length of the fastener 1 by displacing the tension members 8 and 10 in the longitudinal direction. There is. The tooth is shown at 14. A clamping member 16 penetrates a toothed plate or eccentric 13 whose axis is indicated by 15. The axis 17 of the fastening member 16 is different from the axis 15 of the eccentric. The eccentric is rotatably mounted in a recess 18 in the tension member 10, which is designed to absorb forces over a large area. As will be more apparent with reference to FIG. 3, in the present embodiment the flap is
Fixing is performed by screwing the tightening member 16 to the seat member 19 provided in 12. Since the tension member 10 is displaced in the direction of the double arrow 20 according to the relative position of the axes 15 and 17, the fine adjustment of the entire effective length of the fastener is possible. After adjusting the desired length by twisting the eccentric 13 in the void portion 18, it is crimped by screwing the tightening member 16 into the seat member 19, with which the eccentric 13 is attached to the surface of the flap 12 by means of the teeth 14. Securely fixed to. In this case, the distance between the axes 15 and 17 or the maximum possible adjustment stroke during rotation of the eccentric is adjusted so that a fine adjustment can be made over the entire area between the two teeth 11. Selected equal to 11 intervals.

The interaction with ten teeth 11 indicates the shortest possible position. Also, the first tension member 8 interacting with the tension lever 3 has an arcuate end 21 which is the second tension member.
It is clear that it interacts with ten correspondingly contoured stops 22 thus creating a generally aligned surface of the fastener in the closed state. Also in the schematic diagram of FIG.
The eccentric is arranged at a position where the shortest possible total length of the fastener 1 is produced, as is readily apparent from the relative arrangement of the axis 15 of the eccentric plate 13 and the axis of the tightening member 16.

In the diagram of FIG. 3, it is clearly seen that the clamping member 16 penetrates the eccentric 13 which is formed as a toothed plate. In this case, a screw thread 23 for screwing or fixing to the seat member 19 is schematically shown. The flap 12 is not shown in this figure for convenience of illustration.

The embodiment of FIGS. 4 and 5 shows a variant of the clamping element for the eccentric 13, which is also formed as a tooth plate.
In this case, a clamping member, which consists of a pin or tube 24 and whose axis is also indicated at 17, is pivoted about an axis 25 of the eccentric 13 by means of a lever 26 which is movable in the direction of the arrow 27. It can be raised and lowered in the direction of the double arrow 28. In this case, the movement of the fastening member 24 in the direction of the double arrow 28 is carried out by the eccentric arrangement of the shaft 25 of the lever 26, is connected to the fastening member 24 and is connected to a flap (not shown in detail) like the seat member 19. The inversion of the lever 26 presses the tooth 29 against the tooth 14 and thus secures the eccentric 13. For fine adjustment of the total length, the eccentric or toothed plate 13 can be twisted about the axis 15 in the recess of the tensioning member 10, which is also not shown in detail, as in the previous embodiments. Eccentric 13
Has a contoured profile 30 which is curved and therefore generally flat in the closed state.

In addition to, or as an alternative to, the possibility of finely adjusting the relative position and the total length of the fasteners with the fixing of the tension member 10 by means of an eccentric, the position of the member 6 fixed to the tension lever 3 or flap 2 by means of an eccentric. Without fixing to 5,
