Description

Modular balustrade Description Technical field
The present invention relates to a modular balustrade. Background art
Various solutions able to produce modular balustrades consisting of several elements are known. They are widely used in the civil building sector, in particular for balconies and stairs. Balustrades of this type consist, for example, of a set of uprights which are suitably spaced and fixed to the masonrywork structure and provided with means for fastening an upper handrail and a guardrail lying in a vertical plane facing the balustrade. With particular reference to the various known ways of fastening uprights and guardrail, those which are most widely used allow the guardrail to be inserted and extracted into/from the uprights, by means of sliding in the direction of greatest extension of the balustrade. For this purpose, the uprights have a pair of coupling elements which project with the concave parts facing each other and which define a given space inside which the guardrail must be inserted. In view of the shape, which substantially matches the profile of the upper and lower stringers of the guardrail, the combined action of the coupling elements prevents both rotations and translatory movements which are vertical or perpendicular to the plane of the guardrail.
The major limitation of these balustrades consists in the fact that the coupling elements are visible and project, forming a potential obstacle against which people might accidentally knock and an aesthetic constraint as regards the design of the guardrail since they interrupt the aesthetic continuity of the visible parts thereof.
Moreover, the form of the stringers constitutes a decisive constraint on the form of the coupling elements, obliging producers to keep a substantially large warehouse stock, depending on the preferences of the public when choosing a guardrail, or alternatively provide a limited range of different aesthetic solutions. Finally, since the weight of the guardrail bears on the bottom coupling elements, there is greater wear of the latter compared to the upper coupling elements, with the consequent need for more frequent replacement.
The object of the present invention is therefore that of eliminating the drawbacks mentioned above. Disclosure of the invention
The invention, as characterized by the claims, achieves the object by means of a concealable universal fixing device. The main advantage obtained by means of the present invention consists essentially in the fact that each individual element for fixing the guardrail to the uprights is sufficient for preventing movements of the guardrail, except for sliding in the direction in which the balustrade extends.
Moreover, once assembly has been performed, the fixing element, in addition to rigidly fixing the guardrail to the uprights, is not visible from the exterior, so that it does impose any constraint on the aesthetic design of the guardrail nor creates a potential obstacle for users.
The said fixing element may also be adapted to any form of guardrail so that it is not affected by possible replacement thereof with a different model, decidedly facilitating management of the warehouse stock for the manufacturer, without however limiting the possibilities of choice for the customer. Brief description of the drawings
Further advantages and characteristics of the invention will emerge more clearly from the detailed description which follows, with reference to the accompanying drawings which show a non-limiting example of embodiment thereof and in which:
- Figure 1 shows a perspective view of the invention during assembly; - Figure 2 shows a detail of Figure 1; - Figure 3 shows a perspective view of the invention assembled;
Figure 4 shows a front view of the invention assembled; - Figure 5 shows the invention along the cross-section V-V in Fig. 4;
- Figure 6 shows a detail of Figure 5;
- Figure 7 shows a detail of the invention in the form of an alternative embodiment. Detailed description of the preferred embodiment (s)
The present invention relates to a modular balustrade. The modular balustrade (10) shown in the figures comprises a multiplicity of fixed vertical uprights (1) , of which only one pair has been shown for the sake of simplicity, and a removable guardrail (2) which, for obvious reasons of safety, also during assembly and disassembly may be left free to slide only in the longitudinal direction in which the balustrade extends, remaining, however, rigidly constrained both against any rotation and vertical and horizontal movements in a direction perpendicular to the plane which the guardrail (2) itself defines. For this purpose, concealable fastening means (3) are located between the uprights (1) and the guardrail (2) and, on the one hand, ensure that the balustrade has the necessary structural rigidity and, on the other hand, remaining invisible on the outside, do not condition in any way the aesthetic choices.
The constructional solution shown in the Figures, which is preferable for its simple assembly and guarantees as to safety, envisages the use of at least one insert (3a) for each upright (1) , which is stably fixed thereto by means of a screw (5) , and a guide (3b) integral with the guardrail and shaped so as to match the insert (3a) in such a way as to allow, before tightening of the screw (5) , relative sliding of the upright (1) and guardrail (2) .
The form suggested for manufacture of the insert (3a) is a T-shaped cross-section, so that that in this way even only one insert (3a) , provided it has suitable dimensions, allows the guardrail (2) to perform solely translatory movements in the direction in which the balustrade (10) extends. This possibility of displacement of the guardrail (2) is a feature which is used during assembly and disassembly, when the screw (5) is not tightened; once assembly of the guardrail (2) has been completed, in accordance with that shown in Figure 6, tightening of the screw (5) allows both the insert (3a) and the guardrail (2) to be to be locked to the upright (1) .
The guide (3b) may be constructed in various ways: while it must have, in its side facing the upright (1), a recess (4) with a shape able to mate with the insert (3a), it may be made by means of extrusion in the form of one piece with at least one cross-member (2a) of the guardrail (2), as shown in the figures, or may be mounted on the rear side of the same cross-member (2a) , following manufacture thereof.
The main advantage arising from a modular system thus designed consists in the fact that both the insert (3a) and the corresponding form of the guide (3b) may form universally valid solutions for any type of modular balustrade (10).
Obviously identical advantages are derived from the formation of a projection (3c) with a T-shaped cross- section integral with the guardrail (2) and a corresponding seat (3d) on an upright (1) which are shaped so as to match each other. The projection (3c) may be formed as one piece with at least one cross-member (2a) of the guardrail (2) or, alternatively, as is shown in Figure 7, may be mounted on the rear side of the said cross-member (2a) . Similarly, the seat (3d) may also be formed on an upright (1) by subsequent machining or may be mounted on the side facing the guardrail (2) .
As can be seen from Figures 2, 6 and 7, the balustrade (10) comprises means (11) supporting an upper handrail (12) which can be removably fastened to the uprights (1) . Said means comprise a tubular core (11a) which can be inserted inside the upright (1) and locked there with fixing screws, a flange (lib) for resting on the top edge of the upright
(1) and a pair of lugs (lie, lid) separated by a slot (lie).
During assembly, a rib (12a) of the handrail (12) engages in the slot (lie), so that it is possible to tighten the rib (12a) against a lug (lie) by means of a screw or a grub screw inserted into a threaded hole of the other lug (lid) .
Moreover, the slot (lie) has a base (llf) inclined so as to ensure that the support means (11) are suitable for also supporting inclined handrails (12) .
The invention thus conceived may be subject to numerous modifications and variations, all falling within the scope of the inventive idea.
Moreover, all the details may be replaced by technically equivalent elements.
In practice modifications and/or improvements, nevertheless falling within the scope of the following claims, are obviously possible.
