Abstract

A square or rectangular frame of cast or fabricated material (4) is mounted on a support structure (6) with similar frames for appropriate load holding capacity. Each frame has a vacuum inlet within the seal (7) area. A flexible seal (7) of rubber or similar material moulded or extruded into a shape and profile to (7) is secured into the rectangular frame (3). When the object to be fastened to the rectangular frames (5) (a vessel or attachment plate) pushes against the area (1) of the seal (7), it flattens the seal down flat against the area (2) of the seal. The area of seal between 1 and 2 becomes locked together preventing the seal from distorting and maximising grip on the surface (5) when forces are applied in direction (8) on the frames. Vacuum is applied within each rectangular frame pulling the seals into a flat position. The holding frame with rectangular or square pads attached is capable of holding large objects in place.

Description

Vacuum Fastening Pad refer to sheet 7.
A square or rectangular frame of cast or fabricated material
(4) is mounted on a support structure (6) with similar frames for appropriate load holding capacity. Each frame has a vacuum inlet within the seal(7) area.
A flexable seal (7) of rubber or similar material moulded or extruded into a shape and profile to (7) in Fig 1 is secured into the rectangular frame (3).
When the object to be fastened to the rectangular frames(5)
(a vessel or attachment plate) pushes against the area(l) of the seal(7) it flattens the seal down flat against the area of the seal (2).
The area of seal between 1 and 2 becomes locked together preventing the seal from distorting and maximising grip on the surface (5) when forces are applied in direction (8). on the frames.
Vacuum is applied within each rectangular frame pulling the seals into a flat position.
The holding frame with rectangular or square pads attached is capable of holding large objects in place.

Claims

Claims
