Abstract

The invention consists of a pair of parts that allow the frame of an existing gate, which is going to be replaced by a safety gate, to be used, thus avoiding having to carry out masonry and painting work, all without modifying the gate opening. To do this, the device is made up of an interior frame (5) that is adapted and screwed to the existing frame (2) itself, and an exterior frame (6) that fits into the interior frame (5) and is screwed thereto using screws (8').

Description

TECHNICAL FIELD

The present invention relates to a frame that has been specially designed to facilitate the installation of safety gates to replace less secure gates, such as those typically used in storage rooms, garage entrances, multi-purpose or fire gates.
The object of the invention is to provide a frame that facilitates and speeds up the replacement of this type of gate with a safer gate, without the need for masonry work, without having to modify the existing frame and without reducing the opening of said gate, being able to adapt to the different thickness of existing partitions.

BACKGROUND OF THE INVENTION

In the scope of practical application of the invention, such as storage rooms, access to garages, community areas and the like, the gates used are usually of lower quality and less safe against attempted theft or trespass, such that when replacing these gates with safer ones, it is necessary to carry out work in which the current frame is replaced with a safety one.
Much of the cost of installing this type of gate is determined by the placement time (masonry), since it is often necessary to adapt the brick frame after removing the previous gate (levelling, scraping, etc...).
At the same time, sometimes the partition can be damaged and even broken when the gate frame to be replaced is removed from said pre-frame, which further complicates the work.
In short, it is a slow and laborious process that entails multiple drawbacks both from the point of view of operating times and labour costs.
Trying to avoid this problem, invention patent US 2003046886 A1 discloses an adjustable metal gate frame/jamb, which can be mounted on masonry structures or on steel frames, which comprises an interior frame composed of two vertical profiles. and a horizontal one, mounting supports welded to the profiles and screwed to the wall, an exterior frame made up of two vertical profiles and a horizontal one on which a tongue is welded to receive the ends of the vertical profiles of the interior frame, which is equipped with the corresponding hinges, having screws to join both frames, allowing the separation between them to be adjusted depending on the thickness of the partition.
The problem with this solution is that it is an element that "embraces" the wall, where the regulation system that joins both frames to adjust the separation of the profiles and adapt to the thickness of the partition constitutes an extremely prominent element, which significantly reduces the operational dimensions of the gate, in other words, its opening, and may fail to comply with the technical building code, which specifies minimum passage dimensions, which are normally already adjusted to the limit to reduce costs, so this system would be applicable in the best of cases on oversized gates with respect to the technical building code.
However, article 7.1 of the horizontal property law establishes that a special permit from the community is required when the change has an impact on the exterior configuration of the gate or when the size or the placement thereof is to be modified, given that these changes affect the landing or hallway, which is a common element of the building.
Consequently, this solution presents a double problem since, as just said, it reduces the gate opening, and requires permits that prevent the free installation of this type of devices.
A similar situation occurs in the case of utility model ES 1074382 U , which describes an articulated frame for reinforced doors on existing wooden frames, which involves an exterior frame that has two vertical uprights joined by an upper crossbar, and an interior frame that has two vertical uprights joined by upper and lower crossbars, the exterior frame and the interior frame being joined by one of its vertical uprights by means of hinges.
As in the previous case, it is a structure that embraces the existing frame and therefore reduces the gate opening due to the thickness of the assembly of these two groups of profiles.
This problem is also applicable in the framework disclosed in utility model ES 1078556U .
Finally, it should be noted that, although other solutions are known in this regard, these require removing or cutting pieces/parts of the existing frame, so that their direct implementation on existing frames is not possible.

DESCRIPTION OF THE INVENTION

The quick-installation frame for safety gates proposed by the present invention solves in an entirely successful manner the problem previously explained based on a simple but extremely effective solution.
To do this, the invention consists of a frame that is mounted on the gate frame to be replaced, so that the removal of the original frame is not required.
Thus, the gate and the hinges of the gate to be replaced will be removed, maintaining the original frame installed on the corresponding partition.
More specifically, the device of the invention is made up of two complementary parts that are linked together, an interior frame that is fixed to the already installed frame, and an exterior frame that is fixed to the latter, both obtained in high-strength steel.
At this point it should be noted that in the terminology used throughout this report to designate the two frames that participate in the invention, the term "exterior" will always be used to refer to the frame that is closest to the gate opening, while the term "interior" is used to designate a frame that is arranged internally, in other words, between the pre-frame and the exterior frame.
As for the interior frame, same exhibits a Z-shaped profile the three faces of which, orthogonal to one another, adapt externally to the profile of the pre-existing gate frame, so that same is fixed to said pre-existing frame by screwing, through holes made on its intermediate branch, perpendicular to the gate. Screws long enough will be used so that they not only go through the pre-existing frame, but also extend to the partition.
The interior frame finally finishes, in correspondence with the end of its internal branch, in a small bend that will serve as a stop for the placement of the second part or exterior frame, defining a type of groove and remaining flush with the interior free edge of the frame, so that the gate opening does not change.
This second part, which adapts to the first and is fixed by screwing thereto, has an essentially open rectangular profile that defines the visible contour of the frame itself once the gate is installed, so that said profile extends in a lateral wing that overlaps the interior frame in correspondence with the exterior branch of its Z-shaped profile to which it is screwed, extending a greater length, to undergo a bend towards the interior frame, which extends until it abuts the groove defined in said interior frame.
The exterior frame includes the corresponding hinges integrated into one of the vertical uprights thereof, as well as the holes for the lock of the safety gate in the opposite upright, so that it can be quickly and easily installed once the interior frame and exterior frame are installed.
From this structure, a frame is achieved that can be mounted on the original frame assembly of the gate to be replaced, avoiding any type of masonry and painting work, facilitating and speeding up the installation of the new safety gate.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the referenced figures, it can be seen how the device of the invention is provided to facilitate the tasks of replacing a conventional gate (1) with a safety gate, for which it has been provided that, as shown Figure 2, once the original gate and its hinges have been removed (by cutting the same), its frame (2) is maintained, directly fixed to the work partition (3), so that it is not necessary to carry out work on said partition (3).
As can be seen in Figure 3, the frame of the invention is made up of two complementary parts, an interior frame (5) and an exterior frame (6) made of high-strength steel.
The interior frame (5) is obtained from Z-shaped profiles the three faces of which, orthogonal to one another, adapt externally to the profile of the frame (2) of the pre-existing gate, as shown in figures 4 and 5, such that through its middle branch (7), and by drilling the corresponding hole, is fixed to said frame (2) by means of screws (8) that extend to the partition (3), in accordance with what is shown in Figure 8, said Figure 8 showing how said interior frame is flush with the interior edge of the pre-existing frame (2), so that it does not alter the gate opening.
According to another of the features of this interior frame (5), its internal end branch (9) ends in a bend (10) that can have different lengths, as well as be cut to size on site, determining a groove into which one of the ends of the exterior frame (6) is inserted and abuts, as described below.
More specifically, the exterior frame (6) is obtained from profiles having an open U-shaped rectangular configuration, that is, one of the branches of which includes an interior bend (11) that abuts against the external free branch (12) of the interior frame (5), as shown in figure 8, while its other branch is externally bent defining an intermediate section (13) parallel to the gate, which is angled again in the opposite direction to define an end branch (14) perpendicular to the gate which fits and abuts against the interior wall or internal end branch (9) of the groove defined by the bend (10) of the interior frame (5).
In this way, and as shown in figures 6 and 7, the exterior frame (6) is presented and fits on the interior frame (5) to be subsequently screwed thereto by means of through screws (8') through the intermediate section (13) of the exterior frame (6) and through the internal end branch (9) of the interior frame (5), as shown in the cross section of figure 8.
Both the end branch (14) of the exterior frame (6), and the bend (10) of the interior frame (5) are susceptible to incorporating markings for cutting to size at 20mm, 30mm, etc., on site in order to adapt to the different thickness of existing partitions.
As previously stated, the exterior frame (6) includes the corresponding hinges (15) integrated into one of the vertical uprights thereof, as well as the holes for the lock of the safety gate in the opposite upright, so that it can be quickly and easily installed once the interior frame and exterior frame are installed, in minimal time.
In this way, a frame for safety gates is achieved that is easily installed on existing gates, that does not modify its opening, as it is flush with the pre-existing frame, which does not require modifying said frame, and that is adaptable to the different thickness of existing partitions.
