Definitions
- the object of the invention is a support capable of being shaped, the form of which consists of a shell and particles to be formed inside in it, the particles being bound into a unified mass.
- the invention is especially directed at the insole of a shoe, by means of which the position of the foot is corrected into an anatomically correct position.
- the support in accordance with the invention can also be applied to other pieces, in which anatomically individual correspondence is required.
- Supports capable of being shaped are as such known, these being based on the use of a vacuum to stiffen the piece to be formed containing particles. When using a vacuum the support is not, however, formed permanently, the particles eventually begin to move within the piece.
- the intention of this invention is to create a support capable of being shaped, which can be permanently adjusted to the desired form.
- the characteristic features of the invention are presented in the accompanying Patent Claim 1.
- the vacuum technique is used most advantageously as a temporary means of recording the form before the final binding of the particles.
- Other advantageous forms of application of the invention and its advantages are described later in connection with the example of application.
- Figure 1 shows the stages in the manufacture of a support capable of being shaped.
- Figure 2 shows a cross-section of Figure 1 at the point II-II.
- FIG. 1 the stages of the manufacture of the insole are shown in the pictures A, B, and C.
- the A-stage shows a form, in which the padding 3 and particles 2 have been placed inside shell 1. These particles are most advantageously plastic granules, in which there is carbon.
- the mass is then absorbent of microwaves. Substances based on a chemical reaction can also be used here.
- One alternative is to use a liquid, which is sucked into the mass after the vacuum.
- the shell section 1 of the form is airtight and includes the connection 4, which makes it possible to create a vacuum inside the form 1.
- the shaping takes place in such a way that the form is placed on a suitable support, which prevents the mass from flowing further than the desired extreme edge.
- the hose 5 of the vacuum pump is connected to the connection 4 and a vacuum is created inside the form, when the form 1 temporarily stiffens to the desired shape.
- the user can lift his foot from on top of the form and the form in accordance with picture B is placed in a microwave oven. As the particles then absorb the microwave energy they heat up and partially melt into one another and form a unified flexible mass, to which the padding 3 also adheres.
- the shell 1 can be removed, when the final product is an insole 6 in accordance with Figures 1
- the manufacture of the form can be divided into the following stages: a membrane is set on top of the lower form a particle mixture is placed into the hollow formed by the form the creation of an air connection to a suitable point padding is placed on top of the particles an upper membrane is placed on top of the padding and the edges are first place on the membrane - the form is closed with the aid of the upper section, which joins the membranes to one another
- microwave heating high frequency heating can be used, in which case the mass to be heated conducts electricity.
