Cover assembly

1. An assembly, comprising:

a cover assembly, including:

a first rigid element disposed on a rear surface of an elastic body, the first rigid element extending from a first side surface of a first container to a first side surface of a second container, the first rigid element including a first embracing element and a second embracing element, the first embracing element oriented to curve toward a first recess in the elastic body, the second embracing element oriented to curve toward a second recess in the elastic body;

a second rigid element that includes a first side surface, a second side surface and a front surface, the front surface disposed between the first side surface and the second side surface of the second rigid element, the front surface including an opening therethrough;

the elastic body that includes a front surface, the rear surface, a bore extending between the front surface and the rear surface of the elastic body, a first side surface that includes the first recess, and a second side surface that includes the second recess, each of the first and second recesses disposed below the rear surface of the elastic body and above the front surface of the elastic body, the elastic body positioned between the first rigid element and the second rigid element; and

a bolt, which connects the first rigid element with the second rigid element, disposed in the bore of the elastic body and in the opening of the second rigid element;

a first container including a first side surface, a second side surface, a front surface and an edge defined by the first side surface and the front surface; and

a second container spaced apart from the first container, the second container including a first side surface, a front surface, a rear surface and an edge defined by the first side surface and the front surface, wherein:

the first side surface of the first container is positioned closer to the rear surface of the second container than the second side surface of the first container, the first side surface of the first container being at a right angle to the first side surface of the second container;

the first rigid element is positioned at one side of a gap defined by the edge of the first container and the edge of the second container, and the second rigid element is positioned on the opposite side of the gap; and

the first embracing element abuts against the first side surface of the first container and the second embracing element abuts against the first side surface of the second container.

2. The assembly of claim 1 , wherein a longitudinal axis of the first container and a longitudinal axis of the second container define an angle of 60° to 120°, and the first side surface of the first container is positioned next to the rear surface of the second container, and the first side surface of the first container is aligned with the front surface of the second container.

3. The assembly of claim 1 , wherein the first side surface of the second rigid element abuts the front surface of the first container and the second side surface of the second rigid element abuts the front surface of the second container.

4. The assembly of claim 1 , wherein the first side surface of the elastic body abuts the first side surface of the first container and the second side surface of the elastic body abuts the first side surface of the second container.

5. The assembly of claim 1 , wherein the elastic body comprises a trapezoid shaped cross-section in a plane parallel to a longitudinal axis of the bolt.

6. The assembly of claim 1 , wherein the first side surface and the second side surface are each inclined toward the front surface of the second rigid element.

7. The assembly of claim 6 , wherein the first rigid element further includes an opening through which the bolt extends.

8. The assembly of claim 6 , wherein a trapezoid nut is attached to the bolt.

9. The assembly of claim 1 , wherein the first rigid element at least partially encompasses the elastic body.
