摘要： There is disclosed a method of manufacturing a tactile ground surface indicator (100', 200') having a head (5) and a downwardly projecting member connected to the head to be fixedly receivable by a cavity (80) formed through the ground surface (82) for anchoring the head over a ground surface. The method includes positioning an element (6) defining the downwardly projecting member such that an end portion thereof extends through an opening (3) formed through either the head or a piece (12, 12') from which is derived an exterior portion of the head arranged to be visibly exposed when the head is anchored. The element has a plug portion (6A) which is sized so as to be incapable of passing through said opening. The element further has a void (6B) below the upper end. The head or piece is plastically deformed by applying pressure through the plug portion to effect countersinking a part of the plug portion in the head or piece such that material of which the head or piece is comprised flows into said void to occupy it, thereby precluding withdrawal of the downwardly projecting member from the head or piece in an axial direction from the opening to the plug portion.

摘要： There is disclosed a method of manufacturing a tactile ground surface indicator which comprises a head configured to lie fixed over a ground surface, the method comprising plastically deforming a section of metal plate to form a dish shaped piece and machining an exterior of the dish-shaped piece whereby an external profile of said head is formed. There is also disclosed a method of manufacturing a tactile ground surface indicator having a head and a downwardly projecting member connected to the head to be fixedly receivable by a cavity formed through the ground surface for anchoring the head over a ground surface, in which method an element defining the downwardly projecting member or from which that member is derived is positioned such that an end portion thereof extends through an opening formed through either the head or a piece from which is derived an exterior portion of the head arranged to be visibly exposed when the head is anchored, and plastic deformation of the end portion and/or piece is effected to create an interlock between the piece and element.
