Description

This invention relates to a safety device and more particularly to a safety device which prevents damage that threatens a person's foot from below, such as piercing a nail 5 and penetrating the sole of the foot.

Especially in construction work, the risk of stepping on a nail or other sharp object that easily pierces the sole of a regular footwear is quite high. Thus, the costs of such accidents are also high.

10

In construction work, so-called "wedges" are commonly used. safety footwear which takes into account the aforementioned safety risk and therefore has a particularly strong sole. There is no risk of stepping on the nail because the nail does not penetrate the bottom of the standard footwear.

15

In addition, many jobs run the risk of falling objects. When a heavy object falls or falls over a person's foot, it usually results in fractures and bruises. The above-mentioned safety shoe is also often equipped with a toe cap that prevents crushing, especially of the toes.

20 Of course, if enough force is applied to the toes,; ; nothing prevents bruising, but can alleviate the accident

• * «V." damage.

• · "j. Safety footwear are good tools in themselves, but they are also expensive and are not purchased for such purposes where they are temporary or infrequent.

The object of the present invention is therefore to solve the problem of inactivity; '; ma by introducing a safety device that is clearly a standard safety shoe '. cheaper option. It is further intended to provide a security means for a particular. '· ·, Up to 30 limits also gives the toe protection against accidents.

The foregoing and other advantages and advantages of the present invention have been obtained as set forth in the appended claims.

The invention will now be described in more detail with reference to the accompanying principal drawings, which show an embodiment of a security device according to the invention.

5 Thus:

Figure 1 is a plan view of a safety device according to the invention; Figure 2 is a side elevational view of the same safety device; and

Fig. 3 is a side view of the safety device of Figs. 1 and 2 now in the position in which it is in use.

Briefly, the safety device according to the invention is a shaped insole, possibly with an integral toe protector.

Accordingly, Figs. 1 and 2 show the insole part 1 which, by means of a suitable spacer 3, is provided with a toe protection part 2.

20; ; The insole part 1 consists of a suitably comfortable layer of material which is particularly fabric-like in relation to the upper surface facing the foot.

'.., t Underneath the surface layer is a plastic-based, thermoformed, especially substantially uniform layer. This layer is permanent after forming.

25 The material may be a single-use or thermosetting resin, in which case it may be · · re-moldable by reheating.

: * ''. The lowest layer is of a composite structure and consists of a material which is named. for example, to prevent the nail from piercing it and hitting the user's foot # 30. It is clear that the interlayer also contributes to this, together with the lower layer /.

The structure of the lower layer may be similar to that used for example in bulletproof vests. In such structures, their lightness is significant, but 116034 3 has a particularly good protection against puncture. For example, a bullet or knife stroke cannot penetrate such a layer. One example of the basic properties of the structure is that it uses modern high-strength fibers such as Kevlar in a suitable matrix.

5

The lowest layer is also thermoplastic, whereby the bottom becomes a structure with a permanent shape on both surfaces.

As mentioned, an additional feature of the invention is that the toe guard 2 is shaped in one and the same step as the insole itself. In practice, this is achieved by shaping, through a suitable spacer 3, one to one piece with the bottom middle layer to form clear edges 2 '. The height of these edges corresponds to the height of the toes plus a certain distance.

15

The function and purpose of the toe guard 2 are as follows. The spacer 3 is of such a length that when the toe guard portion 2 is folded over the bottom tip, the edges of the cover 2 are substantially aligned along the edges of the insole tip. If a toe guard is not desired, the spacer portion 3 is cut along the front edge of the insole portion and the toe guard portion 20 is removed. If it is to be held again, folding is performed on the insole part 1; and insert the whole into the user's footwear. In this way, * * · 'the foot of the wearer is protected from downward threats and the toes are also somewhat protected.

One function of the spacer, as mentioned above, is to allow the use of only one molding step when making the security tool. Another function is that when the toe guard part is folded into its operating position, shown in Figure 3, the toe guard; '*. the section automatically locates in the right position and position ready to be inserted into the footwear.

In addition to being able to do basic design at the design stage, it can be shaped, emphasized or otherwise individually, if needed. Everything to improve the fit of the aan should probably make the base so that its edges rise slightly from the base.

The invention has been described above in the light of one example only. It is clear, for example, that the material choices within the invention are varied.
