Abstract
An insole (10) secured against displacement inside a shoe, more particularly in the form of a shock absorber, leg length compensator or shock absorber with calcaneal spur relief, on its flat underside, possesses a Velcro fastener comprised of two Velcro portions (11,12), in which one of the two Velcro portions (11,12) is rigid-ly connected to the insole (10) and the other portion (12), on the side located opposite the Velcro fastener side, a side provided with an adhesive for the connec-tion with the shoe (Fig. 1).
Description
1247-9 216g7~
c I N S O L E
The invention relates to a supporting insole, more par-ticularly in the form of a shock absorber, leg length compensator, shock absorber with calcaneal spur relief or suchlike.
BACKGROUND OF THE INVENTION
In orthopedics, insoles are indispensable aids which, however, are only capable of performing their function fully if they constantly assume the same position in relation to the shoe. If the insoles slip out or are displaced from their position inside the shoe, then this is not merely vexatious for the wearer but, on account of the malpositions of the foot, also damaging in the long run.
That is why it is the technical problem of the present invention to provide an insole which is protected against a displacement inside the shoe.
SUMMARY OF THE INVENTION
This technical problem is resolved by means of the in-sole described in the Claim 1, which is characterized in that, on its flat underside, it possesses a Velcro fastener comprised of two Velcro portions, one of the Velcro portions being rigidly connected to the insole and the other portion, on the side located opposite the Velcro fastener side, possesses a side that is provided with an adhesive for the connection with the shoe.
The insole according to the invention possesses the fol-lowing advantages. - Not only is the insole protected against slipping out of position or displacement, but, by means of the Velcro fastener, detachably connected to the shoe. That is why it is possible to remove the insole with the first portion of the Velcro insert from a shoe, where a corresponding Velcro insert is rigidly connected to the shoe. Since it can be constructed so as to be flat, the Velcro fastener allows itself to be integrated into the insole without difficulty so that the Velcro fastener does not have an irritating effect.
Further developments of the invention are described in the subclaims. The adhesive is preferably applied in the form of a film aahesive which is covered by a detachable strip film. This can be realized in the simplest manner in such a way that a double-sided adhesive tape is af-fixed to one Velcro portion~ whereby the externally located side is covered in the form of an originality fastener. This originality fastener is peeled off from the shoe prior to the pertinent Velcro portion being attached so that the exposed adhesive tape side can be secured to the inside of the shoe by being lightly pres-sed against the same.
The Velcro fastener portions are by preference substan-tially designed so as to be round, the round portions are obtained by being stamped out.
In order to additionally prevent that the Velcro faste-ner portion has an irritating or detracting effect, at least the Velcro portion rigidly connected to the insole is embedded in a recess of the insole. When the Velcro fastener portions are interconnected, the film adhesive preferably terminates substantially flush with the sur-face of the insole, i.e. the two Velcro fastener porti-ons are completely integrated into a respective, perti-nently adapted recess of the insole.
~- 216978~
For stability-related reasons, according to a further development of the invention, the Velcro fastener por-tion rigidly connected to the insole is provided with a supporting substrate, by preference of plastic, which possesses a larger diameter than the Velcro connection surface and whose marginal regions are rigidly connected to the insole by being cast integrally with the same.
~y means of this type of attachment it is avoided that the Velcro fastener portion rigidly connected to the insole can be wrenched out when the Velrco fastener is openend. The annular anchoring region, which is achie-ved by it being integrally cast with the insole, is pre-ferably approximately 5 mm wide.
The insole is comprised, as is known in principle from the state of the art, of silicone, which has proved its worth as a soft and flexible material. As already men-tioned in the foregoing, a film which adheres to both sides is employed as film adhesive for the Velcro faste-ner portion which is in connection with the insole, which is connected by being adhesively affixed to the Velcro portion.
Such a fastener is selected as Velcro fastener which, on one of the Velcro portions, possesses locking claws and, on the other Velcro portion, a felt covering, which is mechanically lockable by means of the locking claws.
BRIEF DESCRIPTION OF THE DRAWINGS
An embodiment example of the invention is illustrated in the drawings. Thus i 9. 1 shows a top view onto the underside of the insertion;
~ 2169789 i 9. 2 shows a side view of the insoLe according to Fig.1;
F i 9. 3 shows a top view onto the Velcro portion ri-gidLy connected to the insole, and i 9. 4 shows a side view of this portion according to Fig.3.
ETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The insole 10 depicted in Fig. 1 posseses an arc-shaped configuration adapted to the heel, as is known in prin-ciple from the state of the art. The insole 10 is compri-sed of a flexible soft material, such as silicone. The thickness D is adapted to the orthopedic requirements of the wearer, e.g. in the form of a leg-length compen-sator. The insole, within the rearward heel region which is strongly acted upon by shearing strain, possesses a recess, wherein both the first Velcro portion 11 as well as the corresponding Velcro portion 12 are embedded. At least when subjected to compressive strain, the under-side 13 of the insole terminates flush with the external part 14 of the second Velcro portion 12. On their reci-procally facing sides (see Fig.2), a detachable Velcro connection exists between the portions 11 and 12, in which case the Velcro portion 11 rigidly connected to the insole 10 possesses locking claws 15 and the corres-ponding Velcro portion 12 possesses a felt covering on the Velcro connection side. This felt is covered by a double-sided adhesive tape which, on the surface 14, is covered by a detachable strip film.
As bec omes apparent from the Figs. 3 and 4, the first Velcro portion 11 possesses a supporting substrate 16, from which said locking claws 15 project, by preference in such a fashion that both lateral inflow ducts 17 as well as -also an annular region 18 interrupt the locking -- 216978~
claws. For the fabrication of the insole according to the invention, a first Velcro portion 11 prepared as per Fig.3 is inserted into a prepared recess of the in-sole, following which, with the aid of a hot die while utilizing the lateral inlet duct 17, the silicone flows into the inlet duct or ducts 17 and the annular region 18 in such a way that the substrate 16 and the external locking claws 15 are covered by the silicone and form a rigid connection with the same. The central area of the locking claws 15 remains uncovered and is accessible from the oujtside. The complementary portion 12, which is comprised of a strip of felt, upon which, on its ex-terior, a double-sided adhesive tape is attached which, in the direction toward the surface 14, is covered with a strip film, can now be pressed against the central area, whereby the Velcro connection illustrated in the Figs. 1 and 2 is established. It is in this manner that the insole is distributed to retailers, orthopedics, doctors, etc.
The user will first of all detach the second Velcro por-tion 12 from the first Velcro portion 11, while the co-vering film on the surface 14 still remains on the se-cond Velcro portion. Following this he would, after having peeled off the covering film with the surface 14, on which the adhesive tape side is now exposed, af-fix this second Velcro portion centrally in the shoe so that this second Velcro portion is rigidly connected to the heel area of the shoe. After that he is able to in-sert the insole into the shoe, in which case both Velcro portions 11 and 12 form a detachable connection which effectively prevents a displacement of the insole.
In order to be likewise able to connect the inside in another shoe, it will be necessary for a second Velcro portion 12 to be attached within the heel region of the shoe, this is recommended so as to avoid having to detach the Velcro portion 12 from the first pair of shoes. It is thus possible to change the silicone in-sole from shoe to shoe, whereby in each case, rigid connections between the Velcro portions are provided.
