GATE THAT LIFTS WHILE ROTATING AND COMPACTS LATERALLY AND ITS PROCEDURE OF CONSTRUCTION, TRANSPORT AND INSTALLATION

Description

[0001] The following invention is related to the technical branch of the gates industry and is submitted by the inventor VIDOTTO ANGELO (Italian SSN: VDT NGL 48B10 H706H), a technician with 35 years of experience in the field of technical closing systems for high end gates and related automation systems in full compliance with practical needs, functionality, aesthetic quality and safety.

[0002] The present invention has been conceived in line with those concepts: it generates vertical movement of the gates with a fully innovative construction, transport and installation process.

[0003] So far no professional knowledge could solve difficult situations like the lack of space to go for traditional closing systems like normal or sliding gates, and cope with all the situations of uneven ground line as in mountain area was even more difficult, moreover the installation was never convenient and precise, and setting up automation right on the construction site was quite troublesome both during the installation of the motors and the positioning of safety and control devices.

[0004] Based on "Prior. Art," the opinion of the inventor is that there is nothing that can be directly compared to the present project subject of application for Patent grant, apart obviously from basic application principles like the horizontal axis as pivot point for rotating elements or the spring as force releasing element due on its precise application, which anyway here can be replaced by other similar commercial device like a simple hydraulic or air piston. Acknowledgment can also be found about common materials and accessories needed for the construction, used to simplify and solve problems up to now unsettled.

[0005] Current solutions that work based on the rotation of the horizontal gate element on the vertical plane bring back to simple road blocks, parking barriers and similar or to outdated design concepts, in the inventor's opinion, considered as niche solutions already at their beginning and to be now considered as obsolete based on present day knowledge of functionality, handiness and safety which are requested more and more.

[0006] Those outmoded conceptions covered over aged needs, but based on the writer's opinion can also not be compared to the modern subject of this work, same as the old wood wheel can not be compared to the invention of the more recent ball bearing,

[0007] To the last here above described concept fits the USA 2044 265 (THOMAS GEORGE H) (1936 06 16) as much as the following: USA 2709 862 (LESLIE JR JAMES H) (1955 06 07) general barrier and USA 4 519 164 (PORTER RICHIARD A) (1985 05 29) railway barrier.

[0008] Specific consideration has to be made about FRA 876 140 (EUROPORTE SARL (FR) (2006 04 07) giving credit for the application being used on modern gates, even if limited to swinging gates, but in any case the transport and on site installation easiness claimed by Europorte is related to a different concept and it doesn't include the additional advantages of the system here presented which, as we will later see, makes it possible to be transported by a standard Express courier and to be installed in any condition including uneven ground line, and several others also related to commercial distribution of the product and the system.

[0009] Regarding to the group of inventions mentioned here above I suggest a careful consideration about the work identified as USA 4519164 (PORTER RICHARD) (1985 05 28) because the most recent of all and because searching for previous literature it could induce to consider the movement on vertical plane with rotation on horizontal pivot point (hinge) and balance with spring.

[0010] It has to be immediately said that such invention doesn't aim any kind of gates business, but instead also in this case it just brings back to barriers, presenting a triple bar with horizontal elements during closed position which rotate due to one single pivot "improperly called hinge based on the commercial idea of such an accessory part".

[0011] Moreover that pivot is moved by the gear motor and transfers the movement to all the three bars with sophisticated sets of sheaves because the bars are moving on three separate planes and are positioned in three separate housings, and these bars are each separately balanced by a same quantity of springs and also need a post with three shelf to support the end of each bar.

[0012] It's clear that such a complex construction is now of no any practical interest because every advantage in the concept of construction, functionality and safety is here outdated in reference to the common present requirements, even in the proper business sector (railway barriers).

[0013] The invention here presented as application for invention Patent makes it instead possible to manufacture aesthetically high end gates but at the same time if we want to chose a solution with horizontal slats and with number of slats at regular distance as required by present day regulation, the new concept offers the simple solution as represented in fig,10 also valid for important distances because also manufacturable as double gates because this new concept here described doesn't need supporting posts at the end of the gates having the first gate already a support on the ground thanks to the adjustable accessory component (16) while the second gate hooks, rests and center both with lower and upper beam onto the first one by the accessory (15).
The movement takes place by simple and direct connection to the power take-off (4a) of the gear motor (6) which is simply plugged in, and the balancing comes directly by a single device (7).

PRESENTATION OF THE INVENTION

[0014] The invention is a system according to claim 1.

[0015] The subject of this invention is a device which has integrated in it's whole construction, transport and installation procedure a safe and convenient solution, under any point of view including the economic one and the nice looking, to all the needs of making use of a beautiful closing or property delimitation la difficult situations like Jack of space to operate with normal solutions or uneven ground line at the interested spot.
The system, allows to manufacture any kind of aesthetic need both simple or made of wrought iron, with or without decoration which can also be applied after installation of the full motorized or not motorized device.
The simplicity of the whole procedure will for sure lead to commercial evaluations finding it convenient to use this invention also in normal conditions and in absence of the problems mentioned above.
Core of the system is the set of following parts: cabinet assembly (1), binge post (2), hinges (5), upper connection arm (3), spring coupling (3a) or equivalent adjustable balancing device, lower connection arm (4) with bushing for power take-oft (4a), balancing device (7) and for motorized solutions also the gear motor (6) and the eleetrical control unit (8) all represented together in fig.5 and further detailed in fig.4.

[0016] All components here above mentioned are easy to be fixed to the cabinet assembly by screwing them to it and, once the gates are fixed to the upper and lower connection arms, the whole gate is aesthetically and functionally completed as figured in fig.1.

[0017] The gates can assume any kind of design and some examples are represented in figs.7,8,9,10,13,13A,14A and more can be added as long as they are manufactured conform to the simple procedure that later will be here described.

[0018] The gate this way manufactured as assembly of cabinet (1) and accessories, can be installed close to concrete/masonry gate posts (23) or metal prefabricated ones (28), both on flat floors as shown in fig.1 and fig.13, as well as on uneven ground line as highlighted in fig.13A and more detailed in fig.14 and fig.14A.

[0019] The system has been developed also to be assembled as a whole single unit, which we will call here mono-block. as represented in figs.15,15A obtaining this way a much easier usage as highlighted in fig.16 and fig.16A and where we can value that the three elements of the beam (24) not only join the whole into a mono-block but also make totally safe the handling and installation of the whole structure without any deformation. Moreover the beam (14) will also function as reinforcement cage during the concrete casting for the foundation and fixing to the ground resulting this way in a more simple work with clear money saving.

[0020] The invention has been conceived for a gate dual maneuvering method option, both manually and motorized as an adjustable balancing system based on the weight of the gate is foreseen which allows the manual balanced handling during normal use as well as for emergency operation.

[0021] It's natural that the commercial demand will focus on the motorized solution therefore the system comes with control and safety devices for an efficient automation with present operator and at distance.

[0022] Therefore the gear motor spline shaft (6) is expected to be simply directly plugged into the power take-off bushing (4a) and fixed by the metal plate (6a,6b,6c) to the cabinet side (1) under friction.

[0023] Inside the cabinet (only in one for single gate solutions) finds also place the electrical control unit.

[0024] Furthermore the system comes cable ready for the whole electrical connection and the installation of control and safety devices, therefore the hinge support assembly visible in fig.15B is also including a junction at the bottom (2a) for a horizontal telescopic tube and the shaft for passage and inspection of the cables. The opposite hinge support is exactly the specular same therefore joining the two supports will result in a simple operation by using the tubes (27,27a) which based on different sections will fit one to another as a telescopic tube obtaining this way the correct junction length.

[0025] The left and right hinge supports and the shafts, once joined by the telescopic tube (27 and 27a), set up a kind of sub-frame mounting for the gates and the motorization.

[0026] The needed cables pass all through the sub-frame and the shafts. The telescopic tube is just needed to join the parts and to create a passage from side to side so it can be laid underground. The vertical supports will be fixed to the existing concrete/masonry gate posts (23) or metal prefabricated ones (28) and as already mentioned will hold the hinges (5), connection arms for gates fixing (3) and (4) in fig.15B, and at the same time will function as support to the fixing of the external security photocells (20) using the U shaped protection (19) and the shimming beam (18). The internal security barrier will be fixed directly to the cabinet.

[0027] Not to go unnoticed the inventor wants to highlight that the same way as the cabinet with all the accessories contained therein, also the whole sub-frame as above described becomes important and integral part of the whole system here presented as it provides immediate reference during installation for the correct height positioning: the finished floor level coincides with the height of the shaft (26) and the position of the gate is already predetermined by the position of the hinges (5) already appropriately set during the production phase of the vertical supports (2). Moreover it works as useful structure design to carry out the electrical automation system and to fix control and safety accessories like the security photocells and finally supports the hinges (5) and therefore the whole gate through the upper and lower connection arms (3) and (4).

[0028] It's called sub-frame because it has the whole electrical automation system and also the gate support and connection on it, but alone it can not boast the feature of supporting the gate itself: this function is expected to be taken by the whole sub-frame and gate post once the vertical supports are firmly fixed to the gate posts by screwing if it is a metal one or by rawlplugs if it's a concrete/masonry post.

OPERATION OF THE GATE

[0029] The invention aiming to solve difficult and unresolved situations has also looked for qualified production to achieve a reliable and easy to work product for a safe use.

[0030] Having to make a real gate that moves on a vertical plane and not a simple barrier it was necessary to use two pivot points of rotation with appropriate and special hinges as important parts of the two different rotation groups: the lower one related to connection arm (4) whose function is direct power take-off from the gear motor, and the upper one related to connection arm (3) whose function is to get the balancing force from the spring (7) (or other equivalent device) through the spring coupling (3a).

[0031] This way we obtain a linear and balanced motion both for the motorized operation and a possible manual one.

[0032] Considering the behavior during automatic function, by activating the gear motor (6) in the opening cycle the gate's lower and upper beams will rotate and lift and this makes compacting the vertical poles which become closer and closer white keeping a perfect parallel vertical position. The opening cycle will be completed when all poles will touch one each other (fig.19) which causes on the top end a reduction of the free gateway, equal to the size of the poles multiply by the number of the same poles (for a 160cm large gate the reduction of the free gateway will be about 20cm, but only on the top end).

[0033] During the closing cycle the beams will push down the poles which also in this case will always maintain a vertical position until the closing is completed (figs.1,7,8,9).

[0034] The travel span of the movement can be defined by limit switch or encoder or by operation of the current switch on the electrical unit at floor impact during closing cycle or arrest impact during opening cycle.

[0035] The closing position is given by the adjustable half-moon shaped support (16) and the centering and coupling accessory (15) see fig.1A.

[0036] Any kind of safety for people, objects and animals during the gates operating cycles is assured not only by the adjusted moving torque but mainly by the multi-radius security photocells (20) figs.4,11,12,13,13A which activate immediately if rays are interrupted at any detection of potential obstacles: this is intended for the whole movement of the gates, both inside and outside of the same.

SYSTEM TRANSPORT

[0037] The system allows more than one transport method, satisfying this way the most different needs.

1) One possible way of shipment is to move the whole system as a single piece, a mono-block which is already including the ready to use motorization: by doing so, once installed the system in the prearranged excavation, for it's first start it just needs to plug the already pre-assembled connector into the power supply. like any other home appliance.
4 pieces lifting hooks (25) are arranged as to make it possible to lift the whole mono-block with any crane or forklift or other lifting device by using the appropriate lifting slings as made in fig.16A.
This simple method is economically convenient only for local short range deliveries because the needed crane truck or similar big vehicle can result into a very expensive transport.

2) Another possible way is to reduce the mono-block size to the situation showed in fig.15, easy to be done through the sub-frame telescopic junction of the tubes (27,27a) and by removing the central part of the support frame (24): this operation has to be done without gates which will be shipped with a separate packaging. Following this way even long distance shipping can be done using normal couriers which can offer extremely convenient rates especially after subscription. Once delivered at the installation site the whole system can be set up again at the correct dimension as represented in fig.15A by simply reassembling the support frame (24) and reassembling the gates. Even following this method the system can be transported including motorization and safety devices, because the shafts connection cables are stored inside the shafts during all the time of reduced framework.

3) Finally, another important opportunity has been graphically summarized in figs.17,17A and 17B: all components manufactured conform to all needed processes for the installation can be placed on a standard pallet, thereby resulting in minimal encumbrance with the advantage of getting the lowest shipping rates for any destination by normal and even express courier. The detailed instructions of the manufacturer will allow easy reassembly and installation on site.

[0038] All this can be seen also as a convenient business solution where the manufacturer can rely on a properly trained distributor network which can perform a perfect assembly, installation and start up for a qualified, economic and convenient end user service.

[0039] As already highlighted in the description the product, in his essentiality of complete cabinets with gate supports tor any requested type, gear motors and all accessories related to the automation already connected, can be also used in situations where other prearrangement or gate posts already exist: in that case the system keeps unchanged it's simple installation procedure with direct fixing to the existing post. Beside this, fig.18 also highlights the opportunity to fix the cabinets and the prefabricated gate post directly on the floor. In both this situations the support frame (24) is not needed and the whole installation and transportation activity may result in a more simple solution which based on point (3) will also be cheaper due to the weight cut.

SYSTEM PROCEDURE FOR THE GATES AS COMPLETION OF THE WHOLE

[0040] The gates are an integral part of the system: they are fixed to the cabinets through the connection arms (3 and 4), can be manufactured in many types, plain iron, hammered with spears (11) of many types (see figs.7,9, etc...), different types of tops (see figs.8,11,13A) or in any other shape with several different central decorations (see figs.1,3,7,8,9,13A) and any other as desired or even with a more simple design without spears, tops or decorations.

[0041] The core of each gate includes::
1pc upper and lower beam appropriately drilled. Each single vertical pole will be assembled to the upper and lower beam with a mobile, free to rotate and vibration free coupling: this is obtained by the system illustrated in fig.4 which includes screw (12), brass or bronze washer (12b), bushing for correct coupling (12c). Any decorations are rigidly fixed to the poles, but slightly spaced from related poles as represented in fig.4A. The gates assembled as described will be completed by fixing the cessory components (13,14,14a,15,15a) to the opposite end of the one with the connection arms; a finishing cap, a support and a centering device. This gates can be added and fixed to the whole by specific fastening with screws (9a). In addition gates assembled this way can be shortened and customized, within a certain range, to fit existing gateway dimension.

INSTALLATION

[0042] Simplification of the installation is to be considered already highlighted in the context of all descriptions, however, it will be here briefly summarized by points:

1) for the mono-block solution it's enough to position it into the prearranged excavation without any other foundation frame for the concrete casting, because this function is already covered by the beam (24) as part of the system (see fig.16,16A).

2) for the reduced mono-block solution, once reassembled the central part of the support frame, it's possible to follow the same procedure as at previous point 1): the gates can be fixed to the connection arms before the positioning into the excavation or even after the concrete foundation (see fig.15 and fig.14 for horizontal floor with height difference).

3) If gate posts are already existing on the spot it's enough to fix with screws or rawlplugs the complete cabinets which already include the accessories. The cabinets can be handled with or without pre-assembled gates based on their size (see figs.1,5,11,12,13,13A).

4) In case of already finished floor with no gate posts the cabinet, with his hinges support and metal post, has to be fixed directly to the floor with the angle support and the rawlplugs (29) in fig.18.

Pour cette raison, le système présente une union rotative dans toutes les liaisons entre les supports (9, 10) et les montants verticaux (11) des portes, ce qui permet de réduire l'extension lors de l'ouverture de la porte en comprimant latéralement les éléments verticaux. Grâce à cette construction, le système permet également de réduire la longueur des poutres lors de l'installation pour une adaptation parfaite à la situation réelle sur site.

2. Méthode de construction des portes, caractérisée par l'utilisation du corps (1) et du sous-châssis (2) comme support des éléments supérieur et inférieur de l'ensemble tournant et des portes selon la revendication 1, qui étend la polyvalence du produit dans toutes les conditions possibles, situation, par exemple:

a) à utiliser avec le cadre structurel (24) en tant que solution monobloc complète (voir figure 16A);

b) à utiliser directement sur les colonnes existantes avec fixation au site par des vis ou des bouchons (voir Fig. 11 et Fig. 12);

c) pour une utilisation directe sur le sol avec des bouchons fixés au coin (1b) (voir Fig. 18);

d) pour une utilisation sur des surfaces inégales du sol en compensant les extrémités amovibles du support lors de l'installation;

e) pour une utilisation sur des sols irréguliers, également par fixation directe sur les colonnes du portail, le cas échéant, ou sur le sol.

3. Procédé de transport du système selon la revendication 1, dans lequel:

a) le produit est transporté dans son ensemble en monobloc grâce au cadre structurel (24) et aux crochets correspondants (25);

b) le produit est transporté sous forme de monobloc de dimensions réduites grâce à la possibilité de démonter la partie centrale du cadre structurel (24);

c) le produit est transporté, chaque article étant démonté et placé sur une palette.

4. Système selon la revendication 1, dans lequel: la liaison entre les supports (9) et les bras de liaison (3, 4) est remplacée par un seul élément.

5. Système selon la revendication 1, dans lequel: la charnière est fixée par vissage ou soudage sur le support de charnière (2).

6. Système selon la revendication 1, dans lequel: tout le counterframe est amovible ou est une pièce soudée.

7. Système selon la revendication 1, dans lequel: la liaison entre le boîtier (1) et les charnières est réalisée par vissage ou soudage.

8. Système selon la revendication 1, dans lequel: l'accouplement motoréducteur est inséré directement dans la douille (4a) ou avec un engrenage ou une chaîne et un pignon.

9. Système selon la revendication 1, dans lequel: le concept de transmission et d'équilibrage entre les supports supérieur et inférieur est convertible.
