Description

"ROLDANA EXTRA LIGHT SYSTEM IMPROVEMENT FOR DOORS AND WINDOWS APPLIED IN STONE ALUMINUM GUIDES".

This Utility Model Patent application relates to an Improvement in Extra Light Pulley System for Doors and Windows Applied in Stone Embedded Aluminum Guides, whose features provided provide significant advantages over existing systems on the market for this purpose. greater ease and comfort for its users when opening and closing doors and windows, as the system allows for an extremely smoother sliding of the frame with simple manual movement. also be applied to aluminum guides embedded in the stone (threshold), avoiding accidents or stumbling, due to the unevenness of the floor (indoor environments), the system has great ease of installation in the aluminum profiles and does not need any local preparation for thus developing better performance and low cost, proposing thus giving advantages inherent to its applicability, being its innovative characteristics in the genre.

As you know, in the current market there are two types of pulley systems for aluminum doors and windows, the first system contemplates light loads, its parts are mostly made of injected plastic, and its pulleys also plastic, has no bearings for good sliding, their bearings are as it were spheres that slide on the shaft itself, causing premature wear and over time also rust, which compromises its operation, thus its efficiency becomes low and the product has to be replaced early, not meeting the needs required in the market.

The second system features heavier loads, ie for larger weight applications on doors and windows, the system has its stainless steel side covers, aluminum mounting bracket tabs, stainless steel center pin, aluminum spacer pins, screws also stainless steel, nylon and fiberglass pulley and steel ball bearing. This system has some clearance of the pulleys in relation to the bearing and shaft, which carries them to the sides of the system, impairing their normal bearing and consequently causing wear and malfunction.

In this system there is also a great difficulty in fixing the aluminum profiles of doors and windows, because where the system fits there are certain inserts contained internally within the profiles that necessarily require removal by mechanical machining processes which result in wasted time. and money, making them unviable. There is also a need for constant maintenance for the system to work well. As we have seen, this system has a number of problems that do not really justify its high cost, as they also end up not meeting market needs.

The following are some disadvantages of these two systems in relation to the new patent application:

• Injected plastic housing;

• Do not use qualified bearings;

• Difficult adjustment;

• Early wear of injected pulleys;

• Doors or windows get heavy when pulling;

• Excess of maintenance;

• Steel axles that end up rusting;

• High cost, low performance and low efficiency;

• Very difficult to be fixed to aluminum profiles, it is necessary that the surface of the internal profile be machined;

• Pulleys made of material without mechanical resistance; and

• Excessive clearance on the shaft in relation to the pulleys causing movements in the sides of the profiles. With this in mind, and in order to overcome the drawbacks of the techniques previously employed, the applicant has, after several studies and researches, developed in an intelligent and unusual way the Improvement in Extra Light Pulley System for Windows and Doors. Stone, capable of operating an extremely smooth sliding system due to its low coefficient of friction, whose pulley was designed with special diameter to provide lightness, the radius difference between the bearing and the pulley provides greater torque moment when under load. traction at the ends, maintaining a low friction area between the pulley and the guide planes, efficiently and accurately meeting market needs, where high performance and quality products are used, and can be used in rails and guides embedded in the stone. (Sill), avoiding accidents or tripping, due to the unevenness of the floor internal). The system is very easy to install on aluminum profiles applied for this purpose and does not require any local preparation for installation, just a small fixing screw. The system was developed to guarantee a great performance in its daily use, as well as to satisfy its user financially due to its low cost. The Improvement in Extra Light Pulley System for Doors and Windows Applied in Stone Embedded Aluminum Guides, object of the referred patent application, has a special constitution, whose project was developed with specific characteristics to suit the market needs. The materials used (housing, shafts, pulleys, pins, bearings, rails etc) are endowed with high quality, precision and optimum performance, providing perfect framing in the aluminum cushion profiles.

The following are the advantages of the new system over products found in the market:

• Robust aluminum printed housing;

• Capable bearings (anti-rust);

• Easy adjustment;

• Low pulley wear;

• Extremely smooth glide in the frame;

• Very low maintenance, or almost none;

• Axles of steel and aluminum;

• Low cost;

• Great ease of installation on the profiles (no need for internal machining on cushion profiles);

• Good performance versus cost;

• Pulley made of high hardness polyacetal; • Robust pulleys with diameters designed to facilitate leaf sliding;

• Low coefficient of friction between pulley and stone;

• The system can be applied to aluminum guides embedded in the stone, avoiding accidents;

• The system efficiently supports doors or windows up to 200 kg;

• Pulley can be optional (single, double or triple);

• In some special cases you may use needle roller bearings for high loads;

• The casing rests on the ends of the profiles, giving no possibility of bending where the pulley rests;

• The same system can be used on several lines;

• Stainless steel fixing screw;
