PATENT OFFICE

The object of the present invention extends to perfecting the Spring support according to patent 223787, which allows for more convenient adjustment of the height of the arch and S enables greater stability of the construction.

With the subject of the main patent, the hanging and unhooking of the drawstring caused more effort and practice to adjust the height of the arch. Also was the stress too large at the points of attack, so that the hooks often broke out or the eyes were torn out.

Attempts have therefore already been made to pull the drawstring from two against each other in the longitudinal direction Manufacture sliding parts, the outer ends of which are firmly connected to the longitudinal spring itself, while the two inner superimposed ends are mutually displaceable and lockable.

The adjustment or connecting means selected for this purpose are not suitable for completely eliminating the abuses mentioned, as either a safe setting and determination with them is not possible at all or they break and tear out very easily.

Eliminating this and enabling a safe and permanent setting is that Purpose of the present invention, illustrated on the drawing in three embodiments is.

Fig. Ι and 2 show in bottom view and side view a spring support with a split, attachable drawstring, which is attached to the attachment points the support spring covered in its entire width.

Fig. 3 shows the bottom view of a spring support with a split, firmly riveted drawstring, both parts of which are turned into loops, and

Fig. 4 shows the loop formation of this drawstring in side view.

Fig. 5 shows the bottom view of a spring support with and fixed at one end the other in a clamping coupling attached to the corresponding spring support leg in Shape of a straight slide with adjustable slits of different lengths attached to a drawstring.

Fig. 6 shows the attachment of this straight slide in side view.

The two first embodiments differ only in the shape and the How to attach the drawstring. In essence, they are equivalent. The third Embodiment is instead of a rotary valve; one transverse to the longitudinal direction of the support movable straight slide used.

Claims (3)

α is the well-known supporting arch made of resilient material, the arch height of which should be adjustable according to the respective foot condition or the shape of the foot, or the sensitivity of the patient, while maintaining a certain degree of resilience. For this purpose, a special tension band b is provided under the support spring α , which engages the side legs of the longitudinal spring through the intermediary of a clamping coupling c designed according to the invention in such a way that easy adjustment is also possible for the inexperienced. The subject matter of the invention also allows the most stressed parts to be made more stable. The drawstring can now consist of two parts, as shown, in a manner known per se: These can each be attached to one leg of the support spring α by hanging (Fig. 1 and 2) ao or rivets (Fig. 3 and 4) or be attached in any other suitable manner. Their free ends stand apart. The embodiment according to Fig. 1 and 2, at we ¹ , rather the ends of the longitudinal spring compared to the middle part are somewhat narrowed and pushed through slots of the drawstring, in addition to easy interchangeability of the drawstring, the advantage that the tensile effect on the whole Width of the longitudinal spring α is distributed relatively evenly. The engagement pins d for the clamping coupling c are provided at the free ends. In order to give this a firm, secure fit and thus greater durability to the whole, it is advantageous to bend the free ends of the drawstring (Fig. 1 and 2 and 5 and 6) or make them loop-like (Fig. 3 and 4) to to be able to rivet the heavily used attack pins on both sides. At the same time, the bends will serve as a guide for the clamping coupling c arranged between them. The tensioning clutch itself may be a drawn to 4 flat, straight and transversely moving or to the longitudinal direction of the spring, as shown in Fig. 1, rotating slide differently, with a number of long, opposing incisions e for the engagement pin which, depending on their position, these contract or allow them to move apart and in this way adjust the arch height of the longitudinal spring. The clamping coupling does not need to be arranged between the free ends of a split tension band, but can rather be attached to one leg of the longitudinal spring itself. In this case, the tension band b is not made in two parts, but in one piece and is rigidly or interchangeably fastened with one end to the other leg of the longitudinal spring. The other free end of the tension band b is then brought into connection with the coupling attached to the longitudinal spring (FIGS. 5 and 6). By adjusting the same, the change in the respectively desired arch height of the longitudinal spring takes place in the same easy way as in the other arrangement. In this latter embodiment, the incisions e only need to be provided on one side. Ρλ τ ε ν τ - A ν s ρ r ϋ c η ε: ι. Adjustable spring support for hollow and flat feet with a longitudinal spring according to patent 223787, which serves to support the arch of the foot and is attached under the spring support to limit the span, characterized in that the tensioning coupling of the tension band spring (b) can be moved as a rotary slide or transversely to the longitudinal direction of the support spring Straight slide (c) is formed. 2. Adjustable spring support for arch feet and flat feet according to claim 1, characterized in that the tension band (b) widens towards the fastening points in such a way that it covers the support spring (a) in its entire width with its ends. 3. adjustable spring support for hollow and flat feet according to claim 1 and 2, characterized _go in that the Zugbandschenkel provided with transverse slits are pushed over the ends of the longitudinal interchangeable spring (a). 1 sheet of drawings.
