• This frame 1 is produced in a U-shaped section profile and has a transverse groove 3 of trapezoidal section and obtained by cutting the profile and stapling two cut and folded tabs to form a stiffened cross member 4 forming the bottom of this groove 3.
• On the core 1a of the U-shaped section are also produced on one side of the groove 3, an opening 5 of T-shape intended to form a rear locking part and on the other side of the groove 3, another opening 6, open on this groove 3, intended to form a front locking part.
• the frame also includes a spherical cavity 7 intended to form a blocking part in the “ON” open position.
• This frame 1 can receive an additional part as shown in FIGS. 4 and 5.
• This additional plastic part 8 comes to rest on the core of the metal U-shaped profile forming the frame 1 and is clipped onto the cross-member 4 by clipping pins 8a. It has a lateral opening 8b extending the opening 6.
• the purpose of this complementary part 8 is to form a plastic bearing covering the groove 3 and to avoid metal-to-metal contact, in particular light alloy-sheet susceptible of risks of wear and therefore of taking of plays.
• the groove 3, the openings 5 and 6, the cavity 7 constitute a mounting arrangement contributing to the fixing of the arm.
• Such a mount 1 is associated with a plurality of independent parts called adapters intended to be mounted in the mounting arrangement already described and arranged on said mount, each of these adapters being able to be fixed to a different type of arm.
• two so-called first and second type adapters allow the attachment of first type arms called a pivoting cross member and a second type called lateral pivot arm, already described above and shown in FIGS. 1 and 2.
• This adapter 10 is made of thermoplastic material and has two parts in the form of a bridge and a U-shaped section, called front bridging 11 and rear bridging 12, connected by two longitudinal lateral branches 13, an opening 10a being thus formed between the two bridges.
• This opening 10a is intended for the passage of the pivoting cross member 2A (FIG. 1) of the arm of the first type.
• This opening 10a is of cross section greater than that of the groove 3 of the frame.
• the internal faces of the wings of the two U-shaped bridges are intended to ensure the lateral retention of the adapter on the frame.
• the front bridging 11 has on the inner face of its core an inverted Tee rib 9 and the rear bridging 12 has on the internal face of its core an inverted Tee rib 14. These two ribs provide the vertical connection with the mounting arrangement of the mount.
• the front bypass 11 has a tongue forward which has on its face turned towards the frame a spherical boss 15. This tongue is on its striated external face in order to allow the adapter to be gripped and pushed when it is mounted on Frame.
• the front bridging 11 can also include a second spherical boss 16 on its internal face near its rear end.
• the mounting of such an adapter of the first type on the mount is shown in FIGS. 10 to 12.
• the front rib 9 and the rear rib 14 are introduced respectively into the groove 3 and into the opening 5 of the mounting arrangement.
• the boss 15 is then housed in the opening 6 of the frame.
• the adapter is pushed forward until the boss 15 clicks into the spherical cavity 7 of the frame. Thanks to the folded edge 8 of the opening 6, this boss 15 can thus be housed in the "ON" position by elastic deformation.
• the two inverted T-shaped ribs 9 and 14 lock the adapter on the core of the U-shaped profile forming the frame, by positioning the wings of each T-shaped element under the core of the frame on each side of the openings 5 and 6.
• the frame as shown in FIG. 12 is ready to receive an arm of the first type with a pivoting crosspiece 2A (FIG. 1), this pivoting crosspiece being received in the groove 3 of the frame.
• this cross member is placed in the groove 3
• the adapter is pushed back in the opposite direction, until contact between the adapter 10 and the cross member 2A on the left side (seen according to FIG. 12) of the groove 3 ( Figure 1), where the front bridge 11 partially closes the entry of the groove 3 of the frame and where the possible spherical boss 16 is snapped into the groove 4A of the cross member of the arm ( Figure 1) ensuring the blocking in the "OFF" position, ie closed position and fixed arm.
• the frame 1 can be equipped with the complementary part 8 already described and intended to constitute an anti-wear bearing between the frame and the pivoting cross member of the arm.
• FIGS. 13 to 16 An embodiment of a second type adapter is shown in FIGS. 13 to 16.
• This adapter 20 is made of thermoplastic material and consists of an upper tongue 21 and two lateral flanges 22, 23 joined by a transverse crosspiece 24 of trapezoidal section corresponding to that of the groove 3 of the frame. At the center of this crosspiece 24, is arranged a bore 25 provided with a cylindrical bearing 31 protruding at one of its ends and blind at its other end.
• This adapter 20 is equipped with clips intended to be clipped into the frame, advantageously a front clip 26 intended to be clipped - on the front end of the opening 6, a rear clip 27 intended to be clipped to the rear end of the rear opening 5 and a bottom clip 28 disposed under the cross member 24 and intended to be clipped under the stiffened cross member 4 of the frame.
• the tongue 21 is provided with a transverse groove 29 on its upper face.
• the adapter 20 can also comprise a lateral stop 30 shown in FIGS. 18 and 19.
• This stop 30 is on the same side of the adapter as the bearing 31 and substantially of the same thickness.
• the establishment of a second type arm with lateral pivot is made by fitting this pivot 3B (FIG. 2) into the bore 25 and locking the tab 4B (FIG. 2) in the groove 29 of the adapter 20
• the stop 30 ensures positioning by lateral support of the arm against it and against the bearing 31 and thus limits the clearance between the pivot and the bore 25 of the adapter 20, as particularly visible in FIG. 19.
