MODIFICATION No 1; Optional, Door Control Security Feature. Drawings [12a, d + 13b], Claims: 9 -10; The Door Control Device Security Feature is an optional add on feature to protect the Member / s of the Door Control Device from opportunistic, unauthorised removal. The Member / s have an attractive aesthetic with a stand-alone value so, in some environments may require protection against opportunistic, unauthorised removal. Without the Door Control Security Feature the Member / s of a Door Control Device can be removed simply by raising it to a sufficient height for it to become clear of the Holding Arm. Removing the Member / s from the Holding Arm would render the Door Control Device unfit for purpose. The Door Control Device Security Feature works in conjunction with the Holding Arm, the Sliding Arm, the Back Plate and the Member / s of the Door Control Device in helping to prevent opportunistic, unauthorised removal of the Member / s from the Holding Arm whilst, not interfering with the operational function of the Door Control Device. Door Control Device Security Feature Assembly with Supporting Drawing Reference Fig’s; The Door Control Device Security Feature consists of a Sliding Arm [Fig 7] Back Plate [Fig 10] and Two Connecting Parts. [Fig's 8+9] To Assemble: The Back Plate is placed against the Sliding Arm. [Fig 11a] The central column section of one of the Connecting Parts [Fig 9] is inserted and sits flush into the central hole in the recessed area at the rear of the Back Plate. [Fig lib] The central column of Connecting Part [Fig 9] is then inserted through the central cut out channel of the Sliding Arm and the Two Connecting parts are joined bringing together the Sliding Arm and the Back Plate. [Fig 11c] The primary Member [Fig 1] is then placed inside the Holding Arm. [Fig 12b] The Holding Arm is placed against the Back Plate with the overlap bend of the Sliding Arm sitting on the top axis of the primary Member with the securing holes of the Back Plate and Holding Arm in alinement. [Fig 12c+d] The Door Control Device and the Door Control Device Security Feature can now be secured to a door or other movable barrier via their aligned fixing holes or fixing areas.

Fig 12d: Is a linear perspective rear side view being the embodiment of the primary Member with a Sliding Pad attached inserted into a Holding Arm, connected to a Back Plate with the overlap bend of the Sliding Arm being in its lowest possible position with the head of the Connecting Part [Fig 9] sitting flush against the Back Plate. Fig 13a: Is a linear perspective front view being the embodiment of a Door Control Device and Door Control Device Security Feature connected to the bottom aspect of a door in a perceived location. Fig 13b: Is a linear perspective front side view being the embodiment of a Door Control Device with a Door Control Device Security Feature, connected to the bottom aspect of a door in a perceived location with the overlap bend of the Sliding Arm being in its fully elevated position. The design of the Sliding Arm allows for an optional modification, allowing for additional Members and Extension Arms to be connected to the Door Control Security Feature when an additional Member [mass] is required to be added to the in-situ Member / s and is detailed with Description and supporting drawings references below. MODIFICATION No 2: Additional Member and Extension Arm. Drawings [14,15, 22d + 23], Claims: 4-9-10; A Door Control Device may increase its door holding capability by adding an additional Member [mass] to the in-situ Member / s [Mass], An Extension Arm is an add-on feature connected to the Sliding Arm of a Door Control Device Security Feature required when an additional Member [mass] is added to the in-situ Members. When an Additional Member is connected to the in-situ Member / s it increases the height of the in-situ Member / s rendering the Sliding Arm of the Door Control Device Security Feature unable to raise high enough within the Back Plate for the overlap bend at the top axis of the Sliding Arm to sit on top of the additional Member. The Extension Arm increases of the reach of the Sliding arm allowing the Sliding Arm the extra height required for the Overlap bend at its top axis to sit on top of the primary and Additional Member. The Additional Member is the same height in relation to the height afforded by the Extension Arm. The process of adding an extra Member to a Door Control Device connected to a Door Control Security feature can be repeated as required by connecting an Extension Arm to an existing Extension Arm when an additional Member is connected to the in-situ Member / s. The height dimension of the Primary Member, Additional Member and the central cut out channels of the Sliding Arm and Extension Arm are determined as to work in unison in the prevention of opportunistic, unauthorised removal of Member / s from the Door Control device. Additional Member and Extension Arm Assembly with Supporting Drawing Reference Fig’s; This modification feature consists of an Additional Member [Fig 15] Extension Arm [Fig 14] and Two Connecting Parts. [Fig's 16+17] To Assemble: The Sliding Arm [Fig7] and the Extension Arm [Figl4] are placed together via the matching recessed cut out areas at the bottom axis of the Sliding Arm and at either axis of the Extension Arm. [Fig 18a+b] The central column section of the Connecting Part [Fig 17] is inserted through the aligned holes of the Sliding Arm and Extension Arm [Fig 18c] the Two Connecting parts [Fig 16+17] are then joined, bringing together the Sliding Arm and the Extension Arm. [Fig 19a] The back Plate is positioned against the Extension Arm.[Fig 19c] The Back Plate is then connected to the Extension Arm using the Two Connecting Parts. [Fig's 19b+c + 20a +b] The central threaded column of Connecting Part [Fig 17] is inserted through the central recessed hole at the rear of the Back Plate. [Fig 20a] The central column of the Connecting Part [Fig 17] is then inserted through the central cut out channel of the Extension Arm [fig 20a] where the Two Connecting parts are joined bringing together the Back Plate, Extension Arm and the Sliding Arm. [Fig 20b] The Extension Arm now works in conjunction with the Back Plate in the same way as the Sliding Arm does when connected with the Back Plate. [Figllc] As the Member is raised and before it can become clear of the Holding Arm and the overlap bend at the top axis of the Sliding Arm the central column of the Two Connecting Parts come into contact with the bottom end of the centralised cut out channel of the Extension Arm[Fig 22d] preventing the Sliding Arm from rising enough to allow the removal of the Members from the overlap bend of the Sliding Arm and the Holding Arm. [Fig's 22d+ 23] An additional Member and Extension Arm can be added to the existing Member and Extension Arm whenever more weight[mass] may be required. The Primary Member, Additional Member / s and Extension Arm / s are the correct dimensions in relation to each other to work in unison with the Sliding Arm and Back Plate parts of a Door Positioning Stop Security Device in preventing the removal of the Member / s from the Holding Arm of a Door Control Device from the top axis and the surface at the opposite axis.
