Abstract

A treadplate for a floor of a gangway the treadplate having a basic body of a first material, and a plurality of bones of a second material, wherein the bones are encapsulated by the first material, wherein the second material has a higher elastic modulus than the first material and/or the stiffness of at least one bone of the several bones is higher than the stiffness of the basic body.

First claim

The invention claimed is:

1 . A treadplate for a floor of a gangway, comprising:
a basic body of a first material; a plurality of bones of a second material, wherein the plurality of bones are encapsulated by the first material, and wherein the second material has a higher elastic modulus than the first material, and/or a stiffness of at least one bone of the plurality of bones is higher than the stiffness of the basic body; wherein a gap exists between each one of the bones and a nearest neighboring bone, and a width of a bone in a width direction is larger than the gap, wherein the gap extends along an entire length of each one of the bones and the nearest neighboring bone.

2 . The treadplate according to claim 1 , wherein a majority of the plurality of bones are elongated elements.

3 . The treadplate according to claim 1 , wherein a majority of the plurality of bones are arranged parallel to each other.

4 . The treadplate according to claim 1 , wherein the treadplate has a first end, and wherein a majority of the plurality of bones have end surfaces proximal to the first end, said end surfaces arranged in one plane or in planes that are arranged in parallel to each other.

5 . The treadplate according to claim 1 , wherein
the plurality of bones are made of metal or of plastic; and/or the basic body is made of rubber.

6 . The treadplate according to claim 1 , wherein
a. the basic body has a width direction (B) and a maximum width in the width direction (B); b. the plurality of bones extend along a longitudinal axis (A) that is not directed into the width direction (B) and not directed parallel to the width direction (B); c. the width of a bone in the width direction (B) is at least 0 . 5 % of the maximum width of the basic body.

7 . The treadplate according to claim 1 , wherein:
a. the basic body has a width direction (B) and a maximum width in the width direction (B); b. the plurality of bones extend along a longitudinal axis (A) that is not directed into the width direction (B) and not directed parallel to the width direction (B).

8 . The treadplate according to claim 1 , further comprising a fabric layer.

9 . The treadplate according to claim 1 , wherein the second material has a higher elastic modulus than the first material.

10 . The treadplate according to claim 1 , wherein the stiffness of at least one bone of the plurality of bones is higher than the stiffness of the basic body.

11 . The treadplate of claim 1 , wherein the gangway comprises entry openings for entry into the gangway at opposite ends of the gangway, and
wherein a majority of said plurality of bones are elongated elements that extend in the direction that points from one end of the gangway to the opposite end of the gangway.

12 . A gangway comprising a floor, the floor having a treadplate comprising a basic body of a first material; a plurality of bones of a second material, wherein the plurality of bones are encapsulated by the first material, and wherein a) the second material has a higher elastic modulus than the first material, and/or b) a stiffness of at least one bone of the plurality of bones is higher than the stiffness of the basic body;
wherein a gap exists between each one of the bones and a nearest neighboring bone, and a width of a bone in a width direction is larger than the gap, wherein the gap extends along an entire length of each one of the bones and the nearest neighboring bone.

13 . The gangway according to claim 12 , further comprising entry openings for entry into the gangway at opposite ends of the gangway, wherein a majority of said plurality of bones are elongated elements that extend in the direction that points from one end of the gangway to the opposite end of the gangway.

14 . The gangway according to claim 12 , wherein said floor includes first and second treadplates, wherein at least the first treadplate includes a basic body of a first material and a plurality of bones of a second material, the plurality of bones encapsulated by the first material, wherein the second material has a higher elastic modulus than the first material and/or a stiffness of at least one bone of the several bones is higher than the stiffness of the basic body.

15 . The gangway according to claim 14 , wherein the first treadplate rests on the second treadplate.

16 . The gangway according to claim 14 , wherein the second treadplate rests on the first treadplate.

17 . The gangway according to claim 12 , wherein the second material has a higher elastic modulus than the first material.

18 . The gangway according to claim 12 , wherein the stiffness of at least one bone of the plurality of bones is higher than the stiffness of the basic body.

19 . A method for producing a treadplate comprising:
providing a basic body of a first material; providing a plurality of bones of a second material; and vulcanizing the basic body onto the plurality of bones; wherein the second material has a higher elastic modulus than the first material, and/or a stiffness of at least one bone of the plurality of bones is higher than the stiffness of the basic body; wherein a gap exists between each one of the bones and a nearest neighboring bone, and a width of a bone in a width direction is larger than the gap;
wherein the gap extends along an entire length of each one of the bones and the nearest neighboring bone.

20 . The method of claim 19 , wherein the second material has a higher elastic modulus than the first material, and wherein the plurality of bones are encapsulated by the first material.

21 . The method of claim 19 , wherein the stiffness of at least one bone of the plurality of bones is higher than the stiffness of the basic body.
