SLIDING OPENING TROLLEY, PARTICULARLY SUITABLE FOR THERMAL BRIDGE OPENING OPENING

摘要

The invention relates to a sliding door trolley - in particular suitable for an opening with thermal break - comprising at least one rigid metallic body (24), rolling means (27), and means for supporting the opening comprising at least one support element (25, 26) of rigid thermally insulating material and means for assembling each support element (25, 26) to the metal body (24), adapted so that the opening is carried by the metal body by through the support element (s). In particular, the metal body (24) and each support element (25, 26) have conjugate interlocking structures (28, 29, 30, 31) with which vertical locking means (38, 39) are associated in order to 'prohibit the relative vertical sliding of said support element and the metal body. The invention extends to a method of manufacturing such a cart, characterized in that a metal profile and at least one insulating profile are assembled by fitting and crimping their combined fitting structures, so as to form a rigid two-component profile which is then cut transversely to obtain carriages.
