[0006]

In a shoe constructed according to the invention, a flexible guide flap for a drawstring extending away from the closure housing is provided with a closure housing in the region of each of the two lace holes. Fixed on top of the shoe, in which case the closure housing is fixed on the upper of the shoe at the upper part of the foot by means of two guide flaps. These dimensions allow the rotary pull closure to be secured with its closure device housing in place on the shoe upper without any special construction or increased strength of the shoe upper. Let's train. At the same time, the two guide flaps make it possible to ensure that the corresponding longitudinal part of the pull cord is guided in the region of the closure housing, in particular in the hole for the cord, which is usually provided in the peripheral housing wall. Becomes

The guide groove or channel extends substantially linearly toward or away from the corresponding hole for the cord and is preferably machined in the two guide flaps in a preferred manner. It is machined, which further ensures a reliable guide of the drawstring.

According to the present invention, the pull cord is tightened upward from below along the part of the instep, and the pull cord is provided between the two opposing ends of the flap-like portion of the upper part of the shoe. It works particularly well when applied to one shoe configured to intersect at points. This case is particularly preferred if the shoe is constituted by the features of claim 3.

In this way, the first guide flap acts mainly on the part of the pulling loop of the drawstring located in the region of the instep part or on the tightening part of the drawstring located there. On the other hand, the second guide flap and its guide groove act on the part of the pulling loop of the drawstring which extends to the heel of the shoe or around the opening for inserting the foot into the shoe. Thereby the pull string
In the region of the instep and in the region of the instep of the shoe for inserting the shoe, in particular in the central position, the result is that the shoe is held particularly suitably on the foot.

[0010]

The present invention will be described in more detail with reference to the drawings. 1 shows a shoe according to the invention, in particular a sports shoe,
Shown as racing shoes, tennis shoes, etc. Actually, only one of such shoes is shown.

The shoe according to the invention comprises a sole 1, a shoe upper 2 made of a suitable flexible material, and a rotary pull closure device 3 carried on the upper 2. The upper part 2 of the shoe has two flap-like parts 2a, 2b at the instep part 4 which are constructed in the usual manner and must be fastened to each other. The flap-shaped portions 2a, 2b are arranged substantially symmetrically in this example so that their ends oppose each other at the instep.

The rotary pull closure device 3 is carried by the upper 2 and can be constructed in a conventional manner. For example, there are examples of FIGS. 4 to 7 of European Patent EP-A-41290. Thus, as also shown in FIG. 2, the rotary pull closure device 3 has a closure device housing 5, a rotary actuation knob 6 and one single pull cord 7, which pull cord is in the usual manner on a cord pulley. The lace pulley is not shown in detail, although it may be wrapped around or unwound at.

This pull string 7 is a closure device housing 5
Or, it is inserted into the holes 8 and 9 for two strings provided on the peripheral wall thereof, and the holes 8 and 9 for these two strings are arranged so as to be substantially opposite to each other as shown in FIG. Has been done.
On the outside of the closure device housing 5, the pull string 7 forms an outer traction loop 7a, which
a is a string flexure guide 10 arranged on the two flap-like parts 2a, 2b of the upper part 2 or on its opposite ends.
Is engaged with. In this example, which is well known per se,
In order to pull or release the flap-like parts 2a, 2b of the upper part 2 together, the drawstring 7 is wound in the closure device housing 5 using a rotary actuating knob 6 on a drivable lace pulley or It can be unwound from it, such a cord pulley being mounted rotatably in the closure device housing 5. In this example, the shoe has a drawstring clamp 11 which is located along the instep or the instep part 4 and two flaps of the instep of the shoe. It extends from the lower side to the upper side between the end portions of the strip-shaped portions 2a, 2b that oppose each other, and intersects at several points 12, 12a.

According to the invention, flexible guide flaps 13, 14 for the drawstring 7 are provided with a closure device housing 5.
The guide flap 1 extends in a direction further away from the guide flap 1.
3, 14 are on the closure device housing 5 in the area of each of the two lace holes 8, 9 and preferably in the area of the lower side of each of the two lace holes 8, 9. It is fixed to. The closure device housing 5, i.e. the rotary pull closure device 3 in practice, is equipped with these two guide flaps 13, 1.
It is fixed to the upper part 2 of the shoe at the upper part of the foot with the help of 4. The flexibility of the guide flaps 13, 14 allows them to be adapted in a particularly suitable manner to the shape of the corresponding part of the shoe or the upper part 2. The two guide flaps 13, 14 can be fixed to the closure housing 5 in any suitable way. It is fixed, for example, by being constructed in one piece with a suitable synthetic resin material or by welding the guide flap onto the closure device housing 5. In each case, it gives 2
Guide flaps 13, 14 and closure device housing 5
Form some structural integrity or joints. It can be securely mounted in the connecting position on the upper 2 without the need to specially reinforce or stabilize the upper 2 at this connecting position.

As is apparent from FIG. 2, the guide grooves 15, 1
6 or a similar guide channel extends substantially linearly away from the lacing hole 8 and is machined into two guide flaps 13, 14 by means of which the tensioning The corresponding longitudinal part of the lace can be guided particularly reliably in the area of the closure housing 5, in particular in the area of the holes 8, 9 for the lace.

In this construction, the rotary pull closure device 3 and its closure device housing 5 are preferably at the upper end of the drawstring clamp 11, in particular at the cross point 12 of the drawstring, as shown in FIG. It is located in the uppermost region and offset with respect to the upper part 4 towards the outside 17 of the foot. In this example, the first guide flap has two guide branches 13a, 13b, such guide branches 13a, 1
3b intersect each other, each of which is machined with a guide groove 15, 15a, which, as shown, in particular in FIG. 2, these guide grooves correspond to corresponding guide branches 13a, 13b.
Extend in the same direction and thus intersect each other. First guide flap 13 or corresponding guide branch 13
The mutually intersecting guide grooves 15, 15a of a, 13b are preferably machined in the guide branches 13, 13a at different depths. That is, the guide grooves 15, 15a
Is formed in such a way that the longitudinal portions of the drawstrings 7 guided along and in such guide grooves 15, 15a can intersect without interfering with each other and without rubbing against each other. It

The first guide flaps 13 and their guide branches 13a, 13b intersecting each other extend to the instep part 4 and to the lower side of the uppermost part of the intersection 12 of the drawstrings.
As a result, a cross guide portion for allowing the pull cord to travel to a predetermined extent is formed. That is, the pull string 7 is the first
The guide branch 13a of the upper side 2 of the upper part 2 of the inward part 19 of the foot from above the tip 10a of the flexible guide part of the string, and the hole 9 for the string of the closing device housing 5 is straight and upward.
Extend to. On the other hand, the pull cord 7 is slanted upward and rearward from the other end of the second flap-shaped portion 2b of the instep 2 of the foot 17 on the other end of the flexible guide portion 10b, and the inside 19 of the foot and the shoe It is guided in the heel 20 direction. In contrast thereto, the second guide flap 14 (through the closure device housing 5 or the hole 8 for the lace) provides the shoe heel 20 at the outside 17 of the foot.
Extend in the direction. Thus, outside the tightening portion 11 of the drawstring running on the instep part 4, the corresponding longitudinal part 7b of the drawstring traction loop 7a inserts the foot into the shoe in the manner shown in FIG. It can be guided to the lower region of the upper end 2c of the instep part around the opening 21 for cutting. For that purpose, each of the sliding guide elements 22, 22a for the pull cord 7 is fixed to the upper 2 in the region below the upper end 2c of the upper. The sliding guide elements 22, 22a are made of a flexible material, preferably a synthetic resin, which has particularly favorable friction properties. Furthermore, in this example, one sliding guide element 22 is arranged in a preferred manner so that the tow cord can flex in the region of the heel 20 of the shoe.

Thus, if one considers with reference to FIG. 1 the guidance of the drawstring traction loop 7a, the following will be understood. The first guide flap 13 mainly ensures the guidance of one longitudinal part of the drawstring traction loop 7a extending beyond the upper part 4 or the drawstring clamp 11 and the second guide flap 14 Extending in particular around the upper end 2c of the upper 2 or around the opening 21 for inserting the foot into the shoe, in any case extending below the region of the rotary pull closure device 3. The guiding of the other longitudinal part of the outer traction loop 7a being secured.
Therefore, the upper 2 is manufactured without a prominent or special heel cap (typically used in shoes of this kind). This simplifies the production of shoes and makes the production cost particularly low.

[0019]

According to the invention, a rotary pulling device with guide flaps is simple in construction and economical to wear, but very well overall tightens the shoe on the foot, thus making it particularly reliable and firm. And can hold.
