Description

APPLICATION AREA

This invention relates to a block for a mobile cantilever gate and a method for its manufacture according to the restrictive part of the respective independent claims 1 and 5.

This invention relates to the production of equipment for gates, which are designed to regulate the possibility of vehicles or pedestrians to any property, construction site, company, building or garden.

The unit in accordance with the present invention is intended primarily for installation on mobile cantilever gates, even of significant size, especially to provide access to industrial buildings, or at least for use in residential areas.

BACKGROUND

Cantilever sliding gates of known types typically include a supporting frame that has a lower crossbeam, on the lower part of which a longitudinal rail is fixed along the entire length of the gate.

Under the rail there are two blocks, the supporting structures of which are rigidly attached to the ground at a certain distance from one another with alignment with respect to the direction of movement of the gate.

On the supporting structure of each of the blocks, several wheels without an independent drive are installed, which rotate inside the rail located under the gate for their direction when opening and closing.

Usually this movement occurs automatically and is ensured by an engine mounted inside the riser at the gate and connected by a gear with a gear with a vertical axis, which is coupled with a toothed rail fixed to one side of the gate frame.

It should be noted that each block has two supporting pairs of wheels with horizontal, in general, axes of rotation, which account for the weight of the gate, and at least one steering wheel with a vertical, generally, axis of rotation, which is located between two pairs supporting wheels.

The guide wheels of these two blocks interact with each other to avoid lateral deviations of the gate during movement.

At least one pair of support wheels of each gate is adjustable, and its vertical position can also be adjusted to change the height of the gate after the latter are installed in a position in which said gate is completely suspended. For this, adjustment means are provided that move the axis of rotation of the aforementioned pair of adjustable support wheels.

As you know, at present, the supporting structures of the blocks include a large number of composite elements, and, in particular, they use several plates, which must be interconnected into a single unit using labor-intensive welding operations.

This adversely affects the manufacturing process, which consequently becomes longer and more expensive. In addition, the support structure obtained as a result of this process by assembling numerous components is not mechanically strong enough.

Known types of production processes for the manufacture of blocks often include, inter alia, as final operations, cutting holes into which fastening and / or adjusting screws are screwed. In particular, the guide is generally fixed to the support structure using a screw mounted in a thread in a vertical plate of the support structure. These operations are, among other things, quite time-consuming and adversely affect the rhythm of the production cycle.

The quality of the gate’s functioning to a large extent depends on the accuracy of the production of blocks, since even a minimal deviation from the bases or defects of the supporting element can lead to malfunction of the gate or cause annoying noise.

Complex production modes, which in accordance with this invention are currently used in the manufacturing process, do not ensure the accuracy of the finished product and do not facilitate the installation of gates.

SUMMARY OF THE INVENTION

Under these conditions, the object of the present invention is to eliminate the disadvantages of the currently existing prototypes and to propose a block for mobile cantilever gates, which can be made from a small number of components.

One of the objectives of the present invention is to propose a block for mobile cantilever gates, which would be structurally simple, economical to manufacture and absolutely reliable.

Another objective of the present invention is to propose a block for a mobile cantilever gate that meets high security requirements.

In addition, the aim of the present invention is to provide a quick, simple and economical method of manufacturing a block for a mobile cantilever gate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As for graphic materials, number 1 gives an example of installing a mobile cantilever gate, which is supported by two support blocks 3, 4 according to this invention, on their lower part.

The term "gate" in the framework of protecting the rights of the present invention includes all possible gates, for example, main external doors or gates that move from the open position to the closed position and vice versa, performing the traditional function of regulating the possibility of vehicles or pedestrians to any property, construction site , company, building or garden.

In accordance with the accompanying graphic materials, the gate 1 has a supporting frame 2, which is generally made of steel and which mainly protrudes along the direction of movement X of the gate 1. This supporting frame 2 is formed by a metal frame, that is, a certain number of racks and crossbars. It is usually equipped with painted panels or grilles.

The gate 1 is supported with the possibility of movement in two positions - opening and closing in the direction of movement X - on two blocks 3 and 4, which are located at a certain distance from one another and are generally installed exactly relative to the aforementioned direction of movement X.

Both blocks 3, 4 are located outside the dimensions of the passage opening and are placed at a certain distance from each other, which allows them to provide console support for the gate 1 in the traditional way: one block provides traction and the other supports, depending on the position in which gate 1 - open or closed.

To withstand the mechanical loads that are transmitted by the gates 1, each of the blocks 3, 4 is rigidly fixed to the ground using its own support.

Means are also usually installed (not shown here) for moving the gate 1 along the direction of travel X, which typically include a toothed rail mounted to the carcass 2 of the gate 1 and a fixed motor in a riser near the gate, which is connected by a gear to the toothed rail to allow movement gate 1.

A rail 5 is mounted on the lower part of the gate 1 by welding, mechanical connection and / or fixing screws. This rail is placed, as a whole, along the entire length of the gate 1 and forms an elongated hollow profile, inside which several wheels are installed without an independent drive, as will be shown farther. These wheels without independent drive are able to guide the gate 1 along the direction of movement X between the opening and closing positions.

It should be noted that each block 3, 4 contains a supporting structure 6 formed by a supporting base 7, which must be attached to the foundation in the ground (for example, using anchor fasteners installed in the hole 95 of the supporting base 7), and a supporting element 8, which should fastened to the supporting base 7, which accounts for the weight of the gate 1. On the supporting base 7, adjusting bolts 97 can also be installed along the height of blocks 3, 4.

The connection between the supporting base 7, including a metal plate, and the supporting wall 8 is carried out, as shown in the figure, using two parallel planes 90 extending vertically from the supporting base, and which are fixed mainly by welding 96 and support the bearing wall along the horizontal axis 91 8.

The aforementioned bearing wall 8 of the structural element 6 of blocks 3, 4 has two pairs of support wheels 9, 10 mounted for rotation (in the preferred embodiment, two pairs of support wheels are used, but we can talk about one or three pairs) and are capable, in general, freely rotate on a horizontal axis in the rail 5, as well as a guide wheel 11, which, in General, can freely rotate on a vertical axis in the rail 5.

From a functional point of view, two pairs of support wheels 9, 10 take on the weight of the gate 1 and must rotate in the rail 2 to allow the gate 1 to move, and the guide wheel 11 interacts with the rail to prevent deviations of the marked gate 1 perpendicular to the direction of movement X .

For this, as can be seen in Fig.6, the hollow profile of the rail 5 (indicated by a dashed line) has a tubular shape, opens from below by a longitudinal slot 12 and has oppositely arranged transverse and vertical, in general, walls 13, on which the guide wheel 11 rests, as well as horizontal, generally upper 14 and lower 15 opposite walls, on which the marked two pairs of support wheels 9, 10 are supported.

In accordance with the idea underlying the present invention, the supporting wall 8 of the supporting structure 6 contains at least two profiled plates 17, 17 'rigidly and parallelly connected to each other by means of fixing 20.

These fixing means 20 include rivets, screws or washers, which avoids welding when connecting two profiled plates 17, 17 'and, accordingly, reduces the time of the technological process.

It should be noted that each of the profiled plates 17, 17 'has two first through holes 21 aligned with the corresponding first holes 21' of the other profiled plate 17 ', 17 so that together they form two first sockets 23, adapted to accommodate the first support elements 24 to support two pairs of support wheels 9, 10.

Each of the carrier plates 17, 17 'also has a recess 25 aligned with a corresponding recess on the other carrier wall 17', 17 so that together they form a second seat 26 for receiving the guide wheel 11, which, in turn, is supported with the possibility rotation on the second support element 27.

In addition, on each profiled plate 17, 17 'there is a bulge 28 from the upper profile of the profiled plate, which corresponds to concavity 25, has a recess and is directed towards another profiled plate 17, 17'. Together they form a cavity 29, connected at least partially with the second support elements 27 of the guide wheel 11 and the second socket 26.

The above bulge 28 has a predominantly semi-cylindrical shape obtained by stamping.

As can be seen from Fig.7, these second support elements 27 have at least one first gasket 34 with corresponding holes installed in the second socket 26 above the upper profile of the profiled plates 17, 17 'to hold the inner ring of the bearing 72, on the outer a ring of which said guide wheel 11 is mounted.

The cavity 29 extends vertically downward and ends in the third socket 30, formed by the second holes 31, made by combining with two profiled plates 17, 17 '. Figure 3 shows a profiled plate 17 with a stand 80 installed in the cavity 29 with the upper part 80 'in the second hole 31 of the profiled plate 17'.

The second supports 27 have a stand 80 with a wide upper part 80 'installed in the above-mentioned third socket 32, and a shank 80 ″, fully threaded, installed in the cavity 29. In addition, these second support elements 27 have a locking screw 33 with a head 33 ', which abuts against the inner ring of the bearing 72, and a shank 33 ″, which is engaged with the thread of the shank 80 ″ of the strut 80.

Thus, the bearing 72, supported by the guide wheel 11, is held in said second socket 26 by an inner ring fixed between the head 33 ′ of the locking screw 33 and the spacer 34.

The wide upper portion 80 ′ of the strut 80 is rectangular in shape and connected to the third socket 30 so as to prevent the strut 80 from rotating around its axis.

As a rule, the width of the third slot 30 does not allow the rotation of the top of the rack commercial sizes.

The first support elements 24, supporting two pairs of support wheels 9, 10, have a central rack 37 mounted in the corresponding socket 23 with bearings 50 on two pairs of support wheels 9, 10.

Between the first holes 21 of the profiled plates 17, 17 'and the bearings 50, the second and third struts 51, 52 are installed.

An advantage is that at least one (9) of the two pairs of support wheels 9, 10 can be adjusted in height so that part of the gate 1 in the closed position can be controlled.

For this, the carrier 8 is held above the plane 90 on the support base 7. Under the carrier 8, a screw 92 is installed, which is located in the threaded hole of the support base 7. The screw 92 is mounted on the lower surface of the profile 8 ″ of the carrier 8 and can be screwed or unscrewed for in order to change the inclination of the bearing element 8, as well as the height of the corresponding pair of support wheels 9. The specified height is also supported by the support base 7 with a lock nut 93.

It should be noted that the support base 7 can be made by bending, as a rule, horizontal, on each profiled plate 17, 17 ', forming a supporting element directed in the opposite direction from the bend of the other profiled plate 17', 17.

In the latter case, the tilt adjustment of the block 1 can be carried out mainly as described in the application EP-A-08425418.4, which is given for reference, on page 8, line 22, on page 9, line 18, and in figure 10.

The carrier element 8 is of interest solely from the point of view of higher mechanical loads on the base 7. However, in order to determine the thickness of the profiled plates taking into account the mechanical resistance for the carrier element 8, additional calculations are necessary. In this case, it is preferable to install between the two profiled plates 17, 17 'a reinforcing support element (not shown), consisting of an external profile similar to that which has two profiled plates 17, 17', with holes 21, 31 inside, a cavity 25 in accordance with holes 21, 31 and cavity 25 of two profiled plates 17, 17 '. At the same time, changes in performance should not be made.

The advantage is that the axis of rotation X of the support wheels 9, 10 is located above the middle plane of the point P of the guide wheel 11.

The subject of this invention is also the manufacturing process of a block 3, 4 for cantilever gates 1, in particular of the type indicated above, characterized by simple use.

In accordance with the invention, the method includes the step of cutting a profile of a metal sheet, usually steel, for example, by cutting or laser cutting in order to obtain at least two flat profiled plates 17, 17 'with first holes 21, second holes 31 and cavity 25, as mentioned above.

In addition, a stamping step is provided during which convexes corresponding to the cavity 29 are made on the profiled plates 17, 17 ′ by means of a press.

After cutting, the profiled plates 17, 17 'are mechanically connected to each other at the fixing stage. Moreover, for the manufacture of the supporting element 8 must be prepared corresponding holes 21, 31 and the cavity 25.

The supporting element 8 is rigidly attached to the support base 7 at the assembly stage, a detailed description of which is given below. From this moment, you can begin to install on the carrier element 8 two pairs of support wheels 9, 10 and the guide wheel 11, respectively, using the first and second support elements 24, 27 intended for this purpose, installed in the first sockets 23 and in the second socket 26.

In addition, the molding step includes rigidly attaching the support base 7 to the support member 8 by welding on the support plate, as well as parallel mounting of a pair of metal planes 90 and connecting the support member 8 to a horizontal strut 91 mounted at the ends of the aforementioned pair of planes 90.

During the aforementioned step, the rigid connection of the support base 7 to the supporting element 8 by means of a rectangular bend of the metal sheet, designed to form the profiled plates 17, 17 'and thus form part of the base, which will be installed at the stage of fixing the profiled plates 17, 17 'in the direction opposite to the direction of part of the base of another profiled plate 8.

In this case, the adjustment of the inclination of the block 3, 4 can be carried out, as indicated in the application EP-A-08425418.4, which is given for reference, page 8, line 22, page 9, line 18 and figure 10.

By performing these actions, it is possible to achieve the established goals.

In practical manufacturing, other shapes and configurations may also be used that differ from those indicated above without going beyond the scope of protection.

It should be noted that all parts can be replaced by elements equivalent from a technical point of view, and the sizes, shapes and materials used can be any depending on the needs.
