Description

Railing composed of elements that can be connect, particularly for balconies and stairs.

The present invention relates to a handrail or handrail composed of elements that can be connect, particularly for balconies and stairs.

Railings of this type are already known. However, they suffer disadvantages in terms of their structure, to its assembly method and its flexibility of use.

The document US-A-3 924 834 describes the characteristics of the preamble of claim 1.

The purpose of the present invention is to make structurally simpler and easier to assemble railings without compromising its solidity.

Within the scope of this purpose, an object of the present invention is to provide a railing whose structure can be modified so that it can adapt to installation requirements that must be met in each case.

Another object of the present invention is provide a railing that can be equipped with brackets for support flower pots.

This purpose, these objects and others that they will become more evident later they are reached by a railing for balconies and stairs according to the present invention, which comprises a structure that acts as a parapet and is fixed to vertical tubular posts, characterized in that the cores respective are inserted at the upper ends and lower of said posts, the upper cores having elements for fixing a railing and the cores being coupled rigidly inferior to a base that can be fixed to the masonry of the balcony or staircase, said cores being crossed by some screws to fix the hook-shaped elements in order of anchoring the parapet.

Figure 14 is a sectional view, taken at along the line XIV-XIV of Figure 13.

Referring to Figures 1 to 7, the railing is generally designated by reference number 1 and it comprises a structure 2, hereinafter referred to as a parapet, which applied frontally to a plurality of vertical posts 3.

Posts 3 consist of a section tubular 4 (see in particular Figure 3) which is formed by two combo side walls 5 and 6, a flat front face 7 and a posterior nerve 8. The posterior nerve 8, along with the edges opposite side faces 5 and 6 protruding therefrom, it forms a groove 9 that is closed by a band 10 by means of the elastic fit of the two edges 11 and 12 that are rigidly coupled to the band 10 in two raised parts 13 and 14 that stand out in slot 9 of opposite edges of faces 5 and 6.

Face 7 and nerve 8 form a seat that allows inserting, at the lower end of the tubular section 4, a hollow core 15 having a rectangular cross section and it rises from a nucleus 16 with which it is monolithic.

In the base 16 there are two slots 17 to through which the respective screws 18 are inserted; the base is fixed, by means of said screws, to a part of the masonry 19, for example the floor of a balcony or the steps of a stair.

The base 16 has a part that protrudes towards back and in which a threaded drill is formed 20. A screw is screwed Allen screw 21 (see Figure 2) is screwed into the hole threaded 20 and is provided with a spherical head 21 protruding down to rest on the floor with a plate 22 interposed. Screwing screw 21 more or less completely before the screws 18 are tightened it is possible to lift the base 16 more or less backwards and therefore fix post 4 to plumb, or more generally give it the intended provision, with Regarding the ground.

Two respective walls 22a and 22b of O0151 are they raise from the sides of the base 16, and a transverse wing 23 (see Figure 2) protrudes between those walls backwards of the section Four.

The wing 23 delimits, together with the core 15, a slit 24 that is open down and leans toward above, and forms, together with the core 15, a groove that allows the passage of the posterior nerve 8 of the tubular section 4. A wedge 25 in the recess 24, and a tension screw 26 is inserted in the same. The head of the screw 26 rests a projection 27 of the wing 23, so that screwing said screw blocks the nerve 8 and therefore section 4 is locked against core 15.

The walls 22 and the wing 23 surround a cavity 28 to have access to screws 18, which is closed by a cover 29 made of aluminum or other suitable material that conforms to keep it in position to close the cavity by means of an interlocking coupler with respect to the base 16.

A second core 30 is inserted at the end upper section 4, has the same cross section as the core 15, and is provided with a support flange 31 (see Figures 4 and 5).

Core 30 is fixed within section 4 by middle of a screw 32 that is inserted through the nerve rear 8.

Fixing bolts 33 and 34 are placed through the front walls of cores 15 and 30 and the face front 7 of section 4 and fit two elements 35 and 36 in shape hook to anchor the parapet 2. Tightening bolts 33 and 34, hook-shaped elements 35 and 36 are secured against the front faces of cores 15 and 30 without distorting the wall front of section 4. To allow access to bolts 33 and 34 through cores 15 and 30, the rear faces of the nuclei and nerve 8 of section 4 are provided with respective slits that are large enough to allow bolt heads to pass.

Parapet 2 can have any structure. In the illustrated example, the parapet 2 is constituted by two parallel tubular sections 37 and 38 that constitute the profiles upper and lower parapet. Sections 37 and 38 have slots 39 and 40 for the interlocking seat of the bands contoured 41 and 42. Between contoured bands 41 and 42 there are multiple tubular bars 42a that are fixed by means of screws which are introduced through contoured bands 41 and 42. It get a grill-like structure with the bands contours 41, 42 that are perpendicular to profiles 37 and 38 and They can be used to form parapets for balconies.

However, if railing 1 is to be installed obliquely to follow the inclination of a ladder (see the Figure 10), the parapet has a rhomboidal structure as a grill, with the bars arranged at an angle to the profiles, so that it is vertical when the installation.

The upper core 30 has, above the flange 31, two wings 43, 44 (see Figures 4 and 5), which they are mutually spaced by a groove 45. The wings 43, 44 they have different heights, and their ends are beveled in a substantially triangular shape. The lower wing 43 is arranged in front of the highest 44. Moreover, the 43rd wing is, in the practical, coplanar with the front face 7 of section 4 and its triangular top is facing a threaded drill 46 formed on the rear wing 44.

A raised part 47 in the form of a ramp rises from flange 31, behind wing 44, and is pierced by a drill 48 which is open in an upward direction. The raised part 47 it is arranged on the sides of the wings 43, 44 to form two Highlights or chairs 49 and 50 that are flat on wings 43 and 44 and are concentric around hole 48.

Slot 45 is intended to receive a nerve 51 of a section 52 constituting the handrail of railing 1. The handrail 52 is provided with grooves on the sides of the nerve 51, and the upper parts of the two wings 43, 44 fit into those slots.

The handrail is fixed by means of a screw Allen 53 (see Figure 2) that is screwed into hole 46 and It is adapted to secure nerve 51 against wing 43.

It is clear that the railing described can be install with very simple operations that begin by anchoring the base 16 to the ground and continue with the subsequent placement of the posts 4 on base 16 and conclude with the application of parapet 2 a the posts 4.

Particular attention is drawn to the possibility of vertically aligning the posts acting on the Allen screw 21.

According to a substantial advantage of the present invention, the structure of the cores 15 and 30 allows fixing the Posts without any risk of deformation of the sections. The action of wedge 25 and screw 32 in fact remains confined to strengthen the nerve 8 and therefore the clamping force does not compress the section diametrically.

Another advantage of the railing described It is previously the type of handrail fixing. The shape triangular of the ends of wings 43 and 44 allows in fact to tilt the handrail with respect to the posts and allows to make Usable the handrail also to protect the stairs.

Another advantage of the railing described Previously it allows to support sherds. For this one purpose there are some clamps, marked with the number of reference 54 in Figures 2 and 6, which are constituted by arms that have substantially a U-shape. A fork protrudes from one end of the arm and its teeth 55 and 56 are spaced each other by an extension that is slightly greater than the width of wings 43 and 44.

Teeth 55 and 56 rest on the chairs 49 and 50, on the sides of wings 43 and 44, and are coupled rigidly to the cores 30 by means of a bar 57 that passes to through the open holes 48 and some holes arranged in teeth. Conveniently, the clamp 54 has, below the teeth 55 and 56, a step 58 to rest against the front face 7 of post 3 under flange 31 of core 30. The clamps 54 have a plurality of holes 59 to place the bars that they support the pots 61.

The railing described above is susceptible of numerous modifications and variations, all which are within the scope of the same inventive concept.

Figure 8 is a view of a variation preset to anchor the posts to the vertical wall 62 of the masonry, for example against the end of a balcony or a stairs.

The proposed solution provides the provision of a base 63 aligned with the core 64 that fits the post 3. The base 63 is fixed by means of a bolt 65 that is embedded with cement in masonry 62 and equipped with an Allen screw 66 to adjust the verticality of the post 4. The pin 65 and the Allen screw 66 through an opening 67 of the base that can be closed by a cover 68.

In the embodiment of Figure 8, the core for placing the post 3 is provided with a rib 69 which is shaped to form a seat 70 that is open at the back of the railing in order to place the bolt 33 to fix the element in 35 hook shape and lace walls for two bolts of fixation 71, 72 that are introduced through nerve 8.

Figure 9 illustrates a different embodiment of the clamps 54 to support the sherds. In this embodiment, the fork of the supports for coupling to the posts form two 73 teeth that are curved up like hooks and which, once placed in chairs 49 and 50 of the flanges 31, fit the rib 51 of the handrail 52.

Figure 11 illustrates an embodiment in which a parapet 2 is provided that is composed of the two profiles parallels 37 and 38, in slots 39 and 40 of which are inserted U-shaped sections 74 and 75 to retain the edges upper and lower of a plate or panel 76.

In the embodiment of Figure 12, the parapet 2 it consists of a lower profile 38 to which the bars are connected tubular 42a by means of screws as in the example previously described with reference to Figures 1 to 9.

The top of the bars 42a in turn is connected directly under the handrail, which for this purpose is constituted by a tubular section 77 that has a Longitudinal nerve 78 protrudes forward and below which fix the bars 42a by means of screws 79.

The nerve 78, together with the tubular element 77, forms an interlocking coupling for a band 80 of coverage that complements section 77, so that it gives a Rounded cross section to the handrail.

The version of Figure 12 (and similarly the versions of Figures 11 and 13) also have another feature,  which consists in the fact that section 77 has, in a region down, a slot 81 that has a cross section rectangular and in which the head 82 of an articulated arm fits 83; said arm can be locked angularly, by means of a bolt 84, between two wings 85 rising from the flange 31 of the upper core 30. Head 82 can be placed along the slot 81 and, by means of bolt joint 84, it is possible to tilt with respect to post 3 in order to allow installation oblique of the railing along a ladder.

Finally, Figure 13 illustrates an embodiment for the upper and lower support of a parapet consisting of plates or panels and that, instead of hook-shaped elements 35 and 36, provides the use of two supports 85 that are suitable for be fixed to post 3 by means of bolts 86 passing through of nuclei 15 and 30.

Each support 85 comprises two arms that are diametral with respect to bolt 86 and at the ends of which cylindrical seats are formed to receive bolts 87, 88 which are equipped with tabs 89 and 90. Caps 87 and 88 are introduced through the holes of the plates or panels 91 and 92 that form the parapet of the railing and are fitted by the screws 93 and 94 so as to secure the plates or panels between tabs 89 and 90 and the ends of the support.

In the practical execution of the invention, the shapes and dimensions can be any that agree With the requirements.
