stabilizer arrangement for mobile apparatus such as an access platform having a chassis with a functional component movably mounted thereon for movement between a rest position and a use position, comprises a stabilizer member movably mounted with respect to the chassis and having a ground-engaging portion, the stabilizer member being movable between a retracted condition in which the ground-engaging portion does not engage the ground and a deployed condition in which the ground-engaging portion engages the ground, the stabilizer member and functional component being mechanically interconnected such that, in use, initial functional movement from the rest position of the functional component relative to the chassis causes movement of the stabilizer member from the retracted condition to the deployed condition. ## Claims ### Claim 1 A stabilizer arrangement for mobile apparatus having a chassis with a functional component movably mounted thereon for movement between a rest position and a use position, comprising a stabilizer member movably mounted with respect to the chassis and having a ground-engaging portion, the stabilizer member being movable between a retracted condition in which the ground-engaging portion does not engage the ground and a deployed condition in which the ground-engaging portion engages the ground, the functional component including a guide slot, and an interlock member including a guide member engaging the guide slot in the retracted condition, the stabilizer member and functional component being mechanically interconnected through the interlock member by the guide member in the guide slot such that, in use, initial functional movement from the rest position of the functional component relative to the chassis causes movement of the stabilizer member from the retracted condition to the deployed condition, wherein the interlock member is pivotally mounted with respect to the chassis, the interlock member also being pivotally connected with respect to the stabilizer member, wherein the interlock member includes a portion that cooperates with the functional component, being movable between a locking position in which only initial functional movement of the functional component is possible and a release position in which further movement of the functional component is possible. ### Claim 2 (depends on 1) A stabilizer arrangement according to claim 1, wherein the mechanical interconnection between the stabilizer member and the functional component by the guide member in the guide slot is such that further functional movement of the functional component, after the initial movement from the rest position, is only possible when the stabilizer member is in the deployed condition. ### Claim 3 (depends on 1) A stabilizer arrangement according to claim 1, wherein the interlock member includes a portion that cooperates with or constitutes the stabilizer member, being moved into the release position on movement of the stabilizer member to the deployed condition and being returned to the locking position on reverse movement of the functional component. ### Claim 4 (depends on 3) A stabilizer arrangement according to claim 3, wherein the pivotal mounting of the interlock member with respect to the chassis is between the two portions. ### Claim 5 (depends on 1) A stabilizer arrangement according to claim 1, wherein the guide member comprises a guide roller mounted on the interlock member. ### Claim 6 (depends on 1) A stabilizer arrangement according to claim 1, further comprising a locking mechanism that functions to prevent pivotal movement of the interlock member when the stabilizer member is in the deployed condition. ### Claim 7 (depends on 1) A stabilizer arrangement according to claim 1, wherein the interlock member is pivotally connected with respect to the stabilizer member. ### Claim 8 (depends on 7) A stabilizer arrangement according to claim 7, wherein the interlock member comprises a link arm of elongate form. ### Claim 9 (depends on 7) A stabilizer arrangement according to claim 7, wherein the pivotal mounting of the interlock member with respect to the chassis is located between a portion of the interlock member that cooperates with the functional component and a portion of the interlock member that cooperates with the stabilizer member. ### Claim 10 (depends on 7) A stabilizer arrangement according to claim 7, further comprising a link component pivotally mounted with respect to the chassis and also pivotally mounted with respect to the stabilizer member. ### Claim 11 (depends on 10) A stabilizer arrangement according to claim 10, wherein the pivotal mounting of the interlock member with respect to the stabilizer member is located between the ground-engaging portion of the stabilizer member and the mounting of the link component. ### Claim 12 (depends on 7) A stabilizer arrangement according to claim 7, further comprising a locking mechanism that functions to prevent pivotal movement of the interlock member when the stabilizer member is in the deployed condition. ### Claim 13 A stabilizer arrangement for mobile apparatus having a chassis with a functional component movably mounted thereon for movement between a rest position and a use position, comprising a stabilizer member movably mounted with respect to the chassis and having a ground-engaging portion, the stabilizer member being movable between a retracted condition in which the ground-engaging portion does not engage the ground and a deployed condition in which the ground-engaging portion engages the ground, the functional component including a guide slot, and an interlock member including a guide member engaging the guide slot in the retracted condition, the stabilizer member and functional component being mechanically interconnected through the interlock member by the guide member in the guide slot such that, in use, initial functional movement from the rest position of the functional component relative to the chassis causes movement of the stabilizer member from the retracted condition to the deployed condition, wherein the guide member comprises a guide roller mounted on the interlock member, and wherein the guide slot is asymmetrical, having an overhanging upper wall that engages the guide roller on reverse movement of the functional component and guides the guide roller into the guide slot to return the interlock member to the locking position. ### Claim 14 A stabilizer arrangement for mobile apparatus having a chassis with a functional component movably mounted thereon for movement between a rest position and a use position, comprising a stabilizer member movably mounted with respect to the chassis and having a ground-engaging portion, the stabilizer member being movable between a retracted condition in which the ground-engaging portion does not engage the ground and a deployed condition in which the ground-engaging portion engages the ground, the stabilizer member and functional component being mechanically interconnected such that, in use, initial functional movement from the rest position of the functional component relative to the chassis causes movement of the stabilizer member from the retracted condition to the deployed condition, wherein the stabilizer member and functional component are connected by means of a link member that is pivotally mounted with respect to the chassis, the stabilizer arrangement further comprising a link component pivotally mounted with respect to the chassis and also pivotally mounted with respect to the stabilizer member, wherein the pivotal mounting of the link member with respect to the stabilizer member is located between the ground-engaging portion of the stabilizer member and the mounting of the link component, wherein the link component is arranged to provide for overcentre locking of the stabilizer member in the deployed condition.
