CONNECTING DEVICE FOR TEMPORARILY CONNECTING TWO PREFERABLY PLATE-LIKE PARTS AND NEEDLE SYSTEM FOR SUCH A CONNECTING DEVICE

摘要

The invention relates to a connecting device for connecting two preferably plate-like parts, which is essentially characterized by at least two needles which are connected on the base side to separate carriers, of which at least one carrier is operatively connected to the drive element for actually adjusting the needles, wherein in an initial position of the needles the needle tip are axially displaced with respect to one another and in a bracing position the needle tips are opposite one another in such a way that the supporting areas thereof are situated at the same axial level—The needles have in the region of their tips relative to their mutually facing areas integrated elevations and depressions in order to thereby control the spreading of the needle tips when the needles are actually displaced with respect to one another.

主权项

1. A connecting device for connecting two preferably plate-like parts, in particular for detachable connecting two parts to be bonded,
with a supporting area connected directly or indirectly to the housing of the connecting device for supporting at one of the parts to be connected on the one hand, with supporting areas at least two hook-shaped abutments for supporting at the other of the parts to be connected, wherein the supporting areas of the hook-shaped abutments form the free end of assigned needles, with a system for axially adjusting the supporting areas of the adjustable hook-shaped abutments and for the displacement thereof orthogonal to the axial adjustment direction in order to engage with the supporting areas of the hook-shaped abutments in the other of the parts to be connected, after the hook-shaped abutments (needle tips) have reached through the overlapping openings of the parts to be connected, and with a drive element for axially adjusting the needles, wherein at least two of the needles belonging to a connecting device are connected on the base side to separate carriers, of which at least one carrier is operatively connected to the drive element such that the drive element is suitable to adjust the needles relative to each other in axial direction, wherein in a starting position of the needles (before bracing the parts to be connected) the needle tips are moved axially to each other and that in a bracing position the needle tips are opposite to one another in such a way that the supporting areas thereof are situated at the same axial level, wherein the needles have in the region of their tips relative to their mutually facing areas integrated elevations and depressions, wherein said elevations and depressions are nested into each other in a space saving manner in the starting position of the needles, and wherein the elevations support each other in the bracing position of the needle tips such that the supporting areas are adjusted orthogonally to the axial adjustment direction of the needles.
