RAIL FOR GUIDED SCREEN SYSTEM |
| 摘要 |
A method of manufacturing a guide rail for a zip-like guided screen, comprises: providing an elongate body (10) including a pair of spaced-apart walls (12,14) defining a channel (18) therebetween, each wall (12,14) having a flange (20) projecting laterally into the channel (18) to define a neck region (22) of the channel (18); and plastically deforming the elongate body (10) to reduce the neck region (22) of the channel (18) from a first width to a second width such that the channel defines a keyway for receiving a zip-like retention device, the keyway having a profile which is maintained on completion of the plastic deformation and is configured to allow the zip-like retention device to slide in a first direction along the channel, and to resist movement in a second direction perpendicular to the first direction which would separate the zip-like retention device from the elongate body. |

1. A method of manufacturing a guide rail for a zip-like guided screen, comprising:
providing an elongate body including a pair of spaced-apart walls defining a channel therebetween, each wall having a flange projecting laterally into the channel to define a neck region of the channel; and plastically deforming the elongate body to reduce the neck region of the channel from a first width to a second width such that the channel defines a keyway for receiving a zip-like retention device, the keyway having a profile which is maintained on completion of the plastic deformation and is configured to allow the zip-like retention device to slide in a first direction along the channel, and to resist movement in a second direction perpendicular to the first direction which would separate the zip-like retention device from the elongate body. |
