KNOT FOR UNION OF THE END OF A FIRST METAL PROFILE TO A

FIXED ELEMENT

D E S C R I P C I O N

OBJECT OF THE INVENTION

The present invention relates to a node for joining the end of a first metal profile to a fixed element, usable for example for mounting metal profiles in non-permanent structures, such as pergolas, stands, booths or tents.

BACKGROUND OF THE INVENTION

At present, the assembly of the end of a first metal profile to a fixed element, for example in the assembly of tents or other non-permanent constructions, is frequently carried out by means of external brackets screwed to the profile and to the fixed element (usually another similar profile ), which produces on the one hand perforations in the profiles in untimely areas of the same, and on the other hand the presence of the cartels produces adverse aesthetic effects. In addition, an increase in the joint tension between the profiles cannot be caused by these means, causing poorly rigid structures.

DESCRIPTION OF THE INVENTION

The node for joining the end of a first metal profile to a fixed element (usually a second profile) of the invention solves the noted drawbacks.

According to the invention, the knot comprises:

-a recess made at the end of the first profile,

- a plug of suitable size to be introduced in said recess, and which is provided with a first transverse hole and a second longitudinal hole of smaller diameter than the first hole and which is open towards the outer end of the block; said second hole being crossed by the first hole,

-a plug retaining sleeve arranged in the first hole of said block in positional correspondence with at least a third transverse hole made in at least one side of the first profile to support the longitudinal position of the block inside the pocket of the first profile; said bushing comprising an inner thread and having a transverse through recess in positional coincidence with the second hole of the block and of a diameter similar to that of said second hole,

- a retention rod that is housed in the second hole of the block and through the transverse through-recess of the retention sleeve; said rod comprising an outer head (which is on the outside of the block) widened, and comprising, at least, a transverse recess with a conical bottom or conical trunk whose axis is arranged at a distance from the head equal to or slightly less than the distance between said axis and the fixed element when the knot is mounted,

- a conical tip or conical tip screw / prisoner that is coupled to the inner thread of the retaining sleeve, to enter the conical or conical transverse recess of the retention stem and tend to produce its coaxial centering, and

- the fixed element comprising a recess housing of the outer head of the retention rod, whose recess comprises narrowed edges with respect to the amplitude of the outer head and of width slightly greater than the width of the head and neck of the rod arranged below of your head

In this way, the widened outer head of the retaining rod enters the hollow of the fixed element and is retained at the narrowed edges of said hollow as the screw / conical tip or conical tip is advanced inside the conical or conical trunk transverse recess of the rod of retention, which produces the advance of said rod inwards to coaxially align its transverse recess of conical or conical bottom with the conical tip or conical tip of the screw / prisoner. Since the distance between the transverse recess axis of the retaining rod at its head is equal to or slightly less than the distance between said axis and the fixed element when the knot is mounted, the coaxiality between the screw / prisoner and recess will force the tightening of the profile against the front of the fixed element. In addition, the only visible element of the knot will be the head of the screw / prisoner, which can be flush with the face of the profile where it is inserted, without protrusions seen therefore.
