DESCRIPTION

SAFETY GUIDE KIT FOR SLIDING DOORS

Object of the invention

The present invention consists of a kit for adapting a safety guide in any type of sliding door, especially those commonly used in industrial refrigeration installations or the like, so that it can be easily opened and closed, and is capable of supporting large structural loads At the same time, it provides security to the closure by having technical characteristics and an adequate design, which allows its simple adaptation and assembly, regardless of the characteristics of the door, preventing it from being disassembled or accidentally released, easily, while It is moving, or in a still state.

This safety guide kit allows, most of the newly manufactured sliding doors, and existing ones, to comply with the most demanding safety regulations, without the need to modify or change important parts of its structures, by having means for its Easy assembly and adaptation, as well as disassembly if necessary, regardless of size or dimension.

The field of application of the present invention is within the industry dedicated to the security of opening and closing doors, more specifically to mobile door frames or similar elements for closing gaps.

Technical problem to be solved and background of the invention

As is known, in the installations of sliding elements, there are a large number of mechanisms that allow the movement of said elements with respect to rails or rails configured to facilitate their movement.

This high number of systems or mechanisms are aimed at opening and closing gaps such as doors or windows, either in buildings as well as in small or large constructions, in which elements that allow access or limit their access are required, including its display inside, such as security rooms, isolated cameras, such as refrigerators, or even the rooms of the buildings such as showers or rooms.

One of the objectives of the sliding doors is to establish communication limitations between two environments separated by a wall, so that the door leaf does not occupy a space of the same environments, but that they are integrated within the dividing wall both environments or at least when the opening or closing movement does not invade said environments, remaining parallel and close to the wall or wall.

Another objective of this type of mechanism is to facilitate its use by reducing the effort required to move them, by comprising rolling elements such as wheels, pulleys or bearings that fit on the rails, so that when moving the doors, the turn of said wheels reduces the contact between the surfaces of the rails, requiring little force to produce the displacement.

Therefore, these mechanisms of movement by rolling elements are widely used when the door leaf has a high weight, such as refrigeration doors, or security doors, where large areas are available to facilitate the entry and exit of elements of large volume, but also of wide widths so as not to lose its internal pressure, temperature or structural conditions.

One of the problems that arise when using these mechanisms with closures of large size and weight, is its difficulty to perform the desired movement of the door, since despite having rolling elements, these are ineffective when the load is excessive, causing the deterioration of some of its parts due to unwanted deformations.

Another problem arises with the ease of some mechanisms to accidentally disassemble, since the only contact that the doors have with the wall or frame to which they are assembled is the one that occurs between the wheel or pulley with the rail, being in some cases very small or of inadequate forms and orientations when some effort occurs in contraindicated directions

In addition to the problems mentioned, it is also common for this type of Sliding door mechanisms are affected by external elements that obstruct the rails or rolling elements, especially when they are located at the bottom of the doors, preventing their proper functioning.

An accidental unlocking or unfastening of the sliding mechanisms can generate important safety problems since normally these types of doors are large and of high weight. In order to eliminate this risk, it is usual to resort to the replacement of the complete door with the consequent cost.

There is currently a CE marking regulation on industrial doors, Regulation (EU) 205/2011, which is very demanding with the levels of security that these types of products must offer.

Although several types of sliding door mechanisms are known in the current market, the existence of none that has the same or similar technical characteristics as those claimed here is unknown, since, unlike this, said mechanisms do not They incorporate a load sharing system that improves safety and less with a kit-type morphology, which allows its adaptation to most existing doors in the market, which undoubtedly represents an important advantage in order to avoid the complete replacement of the system enclosure.

Description of the invention

In order to achieve the objectives and avoid the inconveniences mentioned in the previous sections, the invention proposes a new safety guide kit that has a simple mechanism for moving the sliding doors, exerting a reduced effort compared to the size and volume of the door leaf. For this, it comprises means for its adaptation to any door geometry as well as means for its easy anchoring to the surface of said door, lintel or wall.

More specifically, the invention presents a new guide kit for sliding doors, and especially for those doors that, due to their particular size, consistency or more frequently, due to their high weight, such as those used in industrial freezers, require a guide set with features special, by means of which secure connection means are provided in order to minimize the risk of eventual falls of the sliding leaf, after the accidental exit of the upper holding member of the guidance system itself.

The sliding door safety guide kit comprises a first profile which in turn comprises:

- at least two first wheels connected to the first profile by means of a first axle, one for each first wheel, said first axes located in the same transverse position, in a first cavity along the first profile; that is, they are located at the same position from a lateral point of view, but at different longitudinal positions, such as a row, always in a first cavity along the first profile; Y

- at least two second wheels connected to the first profile by means of a second axle, one for each second wheel, said second axles located in the same transverse position along the first profile, in the same way as the first wheels, that is, they are located at the same lateral position, but at different longitudinal positions.

The safety guide also includes a second profile comprising:

- at least one first surface configured so that the first wheel travels rolling longitudinally on it, supporting the stress generated in said displacement; Y,

- a second surface, configured so that the second wheel of the first profile rests and moves rolling longitudinally on it;

where the first profile is configured to fit the second profile and to move longitudinally, once fitted, a certain extension with respect to said second profile;

where the first axis is perpendicular to the second axis and the first surface is perpendicular to the second surface.

The fact that there are two wheels of each type, lies in the need for the first profile to be statically stable with respect to the second, that is, to have two points of support on the first and second surfaces. In the same way, the guide can include more wheels in case you are looking for a greater distribution of loads between profiles.

In addition, the second profile comprises an intermediate section, broken at 90 degrees, comprising:

- a third horizontal surface, located on an inner side of the second profile; and - a fourth vertical surface, continuous and perpendicular to the third surface, located on the inner side of the second profile;

so that the first and the second surface of said second profile are located on an external side thereof.

With this configuration of the second profile, the safety kit comprising support means comprising a straight galce, that is, with a rectangular prismatic shape, said galce being surrounded, totally or partially, by the hollow on the side on which the guide is placed, the third and the fourth surface can be rigidly supported and fixed on it, improving the support of the second guide on the wall of the hole, the third coplanar surface being at a horizontal surface of said galce.

This embodiment with the galce located on the hollow of a wall, is adaptable to any existing configuration of holes. When the dimensions of the galce require it, the assembler will have accessories, such as profiles or the like, to adapt the intermediate section, so that the kit can be installed safely, regardless of the door model.

In one embodiment, the width of the third horizontal surface is greater than a width of the galce of the sliding door to facilitate that universality of the guide, since it is only necessary to use wedges or boards that facilitate installation.

For a balanced load distribution, in one embodiment, the wheel axles are not only oriented perpendicularly to each other, but transversally, that is, from a lateral point of view, they are also inclined relative to the vertical marked by the orientation of the sliding door, that is, by the gravity of the sliding element, an angle within a range selected between 5 and 85 °, when the first profile is fitted to the second profile.

In this way, the contact between the first and second wheels with the first and second surfaces respectively, are opposed, being in perpendicular directions.

In one embodiment, at least one of the elements selected between the first surface and the second surface comprises an inner raceway rigidly joined to the second profile by which the wheels are routed, with the support and displacement of said wheels on the first and the second surface through said inner raceway.

The use of this bearing rail improves the coupling between the first and second wheels with the second profile. This improvement of the coupling is achieved, among other ways, by increasing the contact surface between the wheels and the second profile, having geometries of the sections of the routed wheels oriented with that objective, to be used in different sections of rails.

The use of the inner bearing rail prevents the second profile from requiring a complex manufacturing process that allows to have first and second surfaces of complex sections attachable to wheels of different sections, and allows the use of different types of rails depending on the safety guide

In one embodiment, the inner slide rail has a rectangular section and in another embodiment it has a trapezoidal section, where the wheel support is made.

In this way, the area comprised by the crown generated by the difference is sections of the wheel, has a contact with the side of the inner race, thereby increasing the contact surface and, therefore, the distribution of loads and The stability of the guide.

In one embodiment, the first, the second or the two wheels comprise a truncated conical part and a second cylindrical part, said parts configured to be on track. the wheels on the inner slide rail, when it has a trapezoidal section, thereby increasing the contact surface and, therefore, the distribution of loads and the stability of the guide.

In one embodiment, the safety guide comprises a first stop and a second stop at ends of the second profile that limit the longitudinal displacement of the first profile with respect to the second profile, and block the extraction of the first from the second.

The first profile and the second profile are made of a metallic material selected from the group consisting of aluminum, steel, iron, bronze and a combination of the above.

In one embodiment, the first cavity of the first profile where the first wheels are located, comprising a "U" shaped section, adjusting to the section of said first wheel and allowing the fixed connection of the first axle.

In one embodiment, the second profile comprises a third cavity comprising a "U" shaped section through which the second wheels move longitudinally adjusting to the section of said second wheel and allowing the fixed connection of the second axle.

In one embodiment, the first profile comprises a second cavity with a "C" shaped section configured to rigidly fix the first profile to a sliding door, by means of first connection means.

In one embodiment, the first connection means joining the first profile to the sliding door comprises:

- a square comprising a first plate, configured to rigidly join the sliding door by means of threaded screws, and a second plate perpendicular to the first plate with a through hole;

- a metal bolt that passes through the through hole of the square screwed to two nuts rigidly fixed the metal bolt with respect to the square by tightening; where the head of the metal bolt is configured to fit into the second cavity of the first profile and is tightened to said first profile by means of a nut, fixing the union of the first profile to the sliding door.

In one embodiment, the first and second axes are located in the same cross section of the first profile, that is, they are at the same longitudinal height of the first profile.

In one embodiment, the second profile is configured to be rigidly connected by means of second connection means, to an upper end of a hole in a wall, or to a lintel of said hole depending on whether it comprises it.

Preferred description of embodiment of the invention

As can be seen in figure 1, the described system consists of a guide kit configured to move doors or sliding elements (11) intended to open or close gaps, such as those of a building, cold rooms or the like.

The guide kit comprises two profiles embedded in each other. A first profile (1) of constant section, shown separately in Figure 2, preferably metallic, of aluminum, due to the mechanical, structural and lightness conditions it presents, whose section comprises a first cavity (10) in the form of " U "in which two first wheels (3) are located, one at each end of said first profile (1) and a plate in which two second wheels (4) are located, also at the ends of the first profile (1) .

The first two wheels (3) located in the first cavity (10), and are connected to the first profile (1) by a first axle (5), one for each wheel (3), and the two second wheels (4) are joined to the first profile (1) by means of a second axle (6), so that the axles (5 and 6) limit all the movements of the wheels, except the rotation with respect to its own axle.

The safety guide kit also comprises the second profile (2), also of constant section, shown separately in Figure 2, preferably metallic, and more preferably aluminum. This second profile (2) comprises a first surface (21) on which the first wheel (3) of the first profile (1) rests and slides rolling on it, and a second surface (22) in a third cavity (24 ) in the form of "U", in which the second wheel (4) of the first profile (1) is supported and rolled, when the first profile (1) is coupled to the second profile (2).

The second profile (2) comprises an intermediate section (26), broken at 90 degrees, from which a third surface (261) can be distinguished in a horizontal direction, located on an inner side of the second profile (2) and a fourth surface ( 262) oriented vertically, continuously and perpendicular to the third surface (261), also located on the inner side of the second profile (2).

This intermediate section is configured to rest on a straight galce (27) that is located next to the door opening (11), thereby favoring the union and support of the guide on the wall of the hole.

In this preferred embodiment, the first surface (21) is rigidly connected to an inner raceway (13) of rectangular section, anchored to a fourth cavity (25) in the shape of "C" being partially embedded inside, preventing its rotation and displacement The first wheels (5) are supported and moved on the first surface (21) by this inner bearing rail (13), so that the first wheels (5) have two cylindrical parts, of different diameter, to go on the inner slide rail (13), in this way, a larger bearing surface of the first wheels (3) is achieved by distributing the loads, reducing the stresses generated.

As can be seen in Figure 1, where the fitted profiles are shown, the first axis (5) is perpendicular to the second axis (6) and the first surface (21) is perpendicular to the second surface (22). Additionally, the first (5) and the second axis (6) are inclined 45 ° and 135 ° respectively with respect to the vertical, direction caused by the force exerted by the gravity of the sliding element (11), so that the distribution of the loads be balanced between the wheels (3 and 4) and the surfaces (21 and 22) respectively.

To also achieve a good distribution of longitudinal loads, the first (5) and the second axis (6) are located in the same cross section of the first profile (1) located at the longitudinal ends of said first profile (1).

To make the connection of the sliding element (11), which in preferred cases is a door of great size and weight, to the first profile (1), first connection means (8) consisting of a square (16) are used ), nuts (19), a metal bolt (18) and threaded screws (17), where the first profile (1) comprises a second cavity (7) of a "C" shaped section into which the head of the metal bolt (18) threaded to a nut (19), so that by tightening said nut (19) a rigid connection of the metal bolt (18) to the first profile (1) is made.

For the connection of the sliding door (11) to the metal bolt (18) use is made of the square (16), where a through hole (163) located in a second plate (162) of said square (16), is crossed by said metal bolt (18), which is fixed to the square (16) by tightening two nuts (19) and two washers (20). On the other hand, a first plate (161) of the square (16) is connected to the sliding door (11) by four rigidly threaded screws (17).

The safety guide also comprises a first stop (14) and a second stop (15) at the ends of the second profile (2) that limit the longitudinal displacement of the first profile (1) with respect to the second profile (2). That is to say, that they collide with said first profile (1) or with any of the elements that compose it, preventing the first profile (1) from leaving with respect to the second profile (2). In the lower part of the sliding doors (11), there is a third stop (23) that limits the transverse displacement of said sliding door (11), preventing the profiles (1 and 2) from being disengaged.

The second profile (2) is rigidly connected, by means of a second detachable connection means (9), to an upper end of a hole in a wall or lintel (28), preferably to a metal frame or to a frame capable of supporting high loads transmitted by the sliding door (11).

On the other hand, to prevent the first profile (1) from decoupling from the second profile (2), the security guide comprises a third profile (12) rigidly assembled to the second profile (2) by using the second connection means (9), configured to avoid manipulation of the guide or interference with elements external to said guide.
