Abstract

An assembly device for assembling a gutter (1) to a profiled rod (2) perpendicular in the construction of a greenhouse or a shed, comprises a metal clamp (5) which takes hold on the rod (2). The clamp (5) is U-shaped or V-shaped and can be introduced into a corresponding cavity (14) of the rod (2), opening on the side of the gutter (1). The legs (7, 8) of the clamp (5) have protuberances (10) forming barbed wire which prevent the clamp (5) from leaving the cavity (14) of the rod (2). A support (6) integral with the clamp (5) surrounds the gutter (1).

Description

i The invention relates to a device for assembling a gutter and

  of a perpendicular profiled rod in a greenhouse or in a shed, comprising a metal sheet metal clamp which takes hold on the profiled rod. A similar device is known from the application

  Dutch patent NL-A-7614302.

  This device allows rapid assembly of a

gutter and rod.

  However, to obtain a good assembly, the clamp must be elastic, so that it can be put in place.

snap-in place.

  This assembly device has the disadvantage of being less suitable for the transmission of tensile forces in the rod, while these tensile forces form a preponderant part of the load, being caused by the wind along the greenhouse or hangar. The object of the invention is to describe an assembly device which better supports this form of load. The object is achieved by using a U-shaped or V-shaped clamp which can be slid into a cavity of the profiled rod, opening on the side of the gutter, and which has barbed protrusions, preventing

  the clamp outlet from the rod cavity.

  The clamp, by its construction, can easily

  be inserted into the profiled rod.

  By the protrusions forming barbed wire, it is impossible to get out. In addition, this phenomenon is

  amplified by the fact that the rod is made of aluminum.

  As a result, the steel claw will bite into

  the aluminum of the rod, offering a good grip.

  In the known assembly device, it is necessary to saw a transverse notch in the rod for fixing the claw Following the mounting tolerances, problems arise during the mounting of the roof of

the greenhouse.

  The device according to the invention does not have

not this problem.

  Another advantage lies in the fact that the large tolerances, which occur in practice in the dimensions of the gutter, can easily be eliminated. It is possible that the part of the clamp, leaving the cavity of the rod, can directly enclose the gutter, however it is advantageous to use an intermediate support, integral with the clamp and enclosing the gutter, this in order to be able to give a sufficient thickness for the part of the device, located outside the cavity of the profile, thus ensuring

  sufficient strength and solidity to this part.

  This intermediate support is advantageously

  made from an aluminum profile by cutting.

  According to an advantageous embodiment, this support has a bead, taken in the space between the

tongs of the pliers.

  By this construction, the two legs of the clamp are loaded unevenly by the support, this

  which benefits the reliability of the assembly.

  At least one leg of the clamp is provided with a protuberance, directed inwardly between the legs, and engaged in a groove in the bead of the intermediate support, allowing the assembly of the clamp and the support. The two legs of the clamp are advantageously provided with barbed protrusions, directed towards

  inside and preventing the clamp holder from coming out.

  The support is advantageously constructed in such a way that it can be applied to the interior face of a gutter, open upwards. According to this construction, the path of the charges between the gutter and the rod is as short as possible, which provides

  great stability to the whole.

  In the construction of a greenhouse or a shed, it often happens that a gutter is used with an edge, directed towards the outside A slot provided in the end of the rod, is intended to receive this edge of gutter In the device according to the invention, the cavity for the clamp is advantageously located above

from this slot.

  According to a preferred embodiment, the clamp is

  in stainless steel and the intermediate support in aluminum.

  The invention will be described below by

  reference to the example, illustrated in the figures.

  Figure 1 shows a section of the following device

the invention.

  Figure 2 shows a section of the rod.

  Figure 3 shows a perspective of the pliers and

of the support according to the invention.

  Figure 4 shows a following assembly

  the invention, adapted to another type of gutter.

  The assembly shown in Figure 1 has a gutter 1 and a rod 2 which supports a glass plate 3 The rod 2 and the gutter 1 are assembled

by device 4.

  This device 4 comprises a metal clamp 5 made of spring steel and a support 6, preferably made of aluminum. As it appears from FIG. 3, the metal clamp 5 is U-shaped or V-shaped with two legs 7, 8, provided with protrusions 10 forming barbed wire, directed outwards, each of the legs 7, 8, being further provided a protrusion 11 forming a barbed wire, directed

towards the inside.

  The support 6, shown in Figure 3, is provided with a bead 12, which can be mounted between the tabs 7, 8 of the clamp 5 On both sides of the bead are provided grooves 13, into which the protrusions 11 snap when mounting the

clamp 5 on the bead 12.

  In FIG. 1, the protrusions 11 are shown, introduced into the grooves 13 This FIG. 1 also shows that the protrusions 10 have

  bit into the material of the rod 2.

  As illustrated in FIG. 2, the profiled rod 2 has a closed central section, provided

  a constriction forming a recess 14.

  The clamp 5, secured to the support 6, is introduced into this recess The protrusions 10 forming barbed wire, get caught in the walls 15, 16 opposite the recess 14 of the profiled rod 2 The glass plates 3 can be introduced into the

rod 17 slots 2.

  As shown in Figure 1, the gutter 1 has an edge 18, directed outward and mounted in a slot 19 opening from the rod 2 on the side of the

gutter 1.

  Profile 2 is blocked in the direction

  vertical with respect to the gutter 1.

  The support 6 is provided with a tab 20 directed downwards while bearing on the inner face 21 of

the gutter 1.

  The support 6 is further provided with a tab 28 parallel to the bead 12 and intended to be taken in the

  cavity 29 of the profiled rod 2.

  The assembly is done as follows: First we mount the rod 2 with its slot 19

  on the outer edge 18 of the gutter 1.

  Then we slide the metal clamp 5 with the

  support 6 in the cavity 14 of the rod 2.

  As soon as the face 22 of the tab 20, the face possibly made rough, comes into contact with the inner face 21 of the gutter 1, the assembly is ready. As the protrusions 10 forming barbed wire have bitten into the opposite interior surfaces 15, 16 of the profiled rod 2, the clamp 5 and the support 6 cannot

move more.

  So we get quickly and easily

reliable assembly.

  This assembly has good qualities of resistance and solidity following the direct path of the lines of force between the rod 2 and the gutter 1, that is to say the shortest path by the tab 20 of the support 6 which may have sufficient thickness required. Figure 4 shows the same assembly but applied to an alternative form of gutter, having a closed profile 23, on which the gutter 24 proper is mounted by means of supports 25 fixed to the profile 23

by the bolts 26.

  The gutter 24 is provided with an edge 27

  upright, with an outer lip 28.

  This lip 28 is taken in the slot 19 of the

rod 2 profiled.

  This allows an assembly identical to that

illustrated in figure 1.
