Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The invention relates to an injection molded toe cap (Schuh-ka) made from thermo-tTr plastic composite material for safety shoes.
ppe), this toe gear connects both sides 1
, the upper edge of which is joined by a panel, and the lower edge of which is provided with a heli-strip, which further extends to the floor. Bar (Baden)
riegel) or can be configured at least partially as a floor panel.

Problems that Prior Art and Inventions Try to Solve For example, safety shoes worn at work, mountain climbing, and when playing ice hockey prevent injuries to the front of the foot from sudden forces, such as in the case of falling objects. It is equipped with a sturdy toe cap. German standard 484
Requirements such as those required for 3 have been met hitherto by steel caps, but these steel caps have not been very comfortable for the foot due to their large weight and the high thermal conductivity of steel.

The purpose of the invention is to provide comfort for one foot, in particular the block drop test according to German standard 4843 (Fallkei II).
A light, stable structure that can be manufactured as simply as possible, without causing injury to the front part of the foot, even if intense, sudden stresses are applied to the front part of the foot, such as those specified by the Find the toe cap.

Means for solving the problem This object is achieved according to the invention by reinforcing the front and side walls at least partially in the area of the upper part of the edge of the panel by means of a bulge, which bulge is At the same time, it stands approximately to strengthen the riverside corner's resistance to bending.

By raising and widening the upper panel by means of bulges in the area above the front and/or side walls, while strengthening the tips and panels at the same time, a frame-like support structure is formed from the individual surfaces; The support frame structure is extremely rigid due to its spatial arrangement and corner configuration, so that forces even in the case of very strong impacts are absorbed and safely and reliably transmitted through the sides to the sole.

Although the can knob is thicker than the steel camp (
Maximum - height 8-8-12mm, bulge width 8-20+
The synthetic toe cap also improves the comfort of the feet as the coldness gradually escapes. After all, the cap can be manufactured and sold in one work cycle, which has significant production and economic advantages.

Several other examples of hJEr are described in the dependent claims.

A smooth transition to the rear of the shoe is thus achieved by a slope of one ray in the direction of the free end of the side wall, which improves the appearance and covering of the leather and J().

Particularly at the height of the shoe, it is advantageous to make the front part thicker, since watery shocks are absorbed by the child. At the same time, a spatial frame structure effect 44 is created by this means.

In order to have a clear and stable characteristic, the side part has grooves in the direction of L, so that one person panel and /y
The bar is flexibly connected, which makes it suitable for this structure.
By filling the recesses formed by the bulges and panels that will only receive cargo loads, safety can be increased, especially in the case of sharp objects falling directly. This space can be filled by spraying it with the same material used for the toe cap. However, it is also possible to introduce flexible plastics into the space that have a large energy absorption capacity. Finally, however, a cushion structure can also be incorporated, which can be installed later.

It has been demonstrated that synthetic materials of the Makrolon type with the following properties are suitable.

Part 1 of corner 8 is reinforced by a bulge, and this bulge is created by panel 4 to create a space 10. ), the y radius is a specific value (for example 101)

A toe cap is illustrated in FIGS. 3 and 4,
In this figure, the front part 2 and/or the side wall 3 together with the bulge 9 and the filling of the space 10 form a uniform support means 12. The front part 2 is reinforced, 11.
