CONSTRUCTIVE ARRANGEMENT INTRODUCED IN A MOTION TRANSMITTER MECHANISM APPLIED TO A SLIDING GATE

Description

1 / 5 CONSTRUCTIVE ARRANGEMENT INTRODUCED IN A MOTION TRANSMITTER MECHANISM APPLIED TO A SLIDING GATE 1. This Utility Model Patent refers to a constructive arrangement introduced in a motion transmission mechanism applied to a sliding gate, notably developed to extend the durability of the gate's sliding motion, prevent the pulley from coming out of the guide, prevent contact between the sliding gate and the fixed base so as not to generate friction and damage to both, in addition to enabling easy maintenance of the motion transmission mechanism; 2. Said motion transmission mechanism is characterized by a drive assembly composed of a pair of pulleys, one pulley being vertical, enabling the sliding gate to move on the fixed base, and the other pulley being horizontal, providing rigidity and firmness to the gate, preventing it from moving in a pendulum-like manner, which could generate friction between the parts. Disadvantages: 3. As is common knowledge, manual or electric sliding gates are widely used in homes, commercial establishments, etc., and are basically configured by a fixed panel, which can be made of wood, metal, or aluminum, mounted below a guide and moved by means of a sliding mechanism. 4. One of the main drawbacks of this mechanism lies in a series of human and climatic factors, such as guide width, pulley thickness, wind, rain, etc., which can generate a pendulum-like movement in the gate, causing excessive swaying, resulting in friction between the fixed base of the guide and the gate, which can cause eventual damage, or even the pulley breaking and the gate falling. Petition 870250100892, dated 04 / 11 / 2025, page 4 / 11 2 / 5 Solution: 5. This Utility Model Patent aimed to solve the existing problems in the motion transmission mechanism applied to sliding gates. By introducing a new pulley perpendicular to the pulley that allows the gate to move on the fixed guide, it provided stability to the assembly, solving the existing problems of fragility, friction, instability, and breakage. 6. Therefore, with the aim of solving these inconveniences and offering a practical, safe, and efficient solution, the device in question was developed. It also presents several benefits, which can be highlighted as follows: • Low cost; • Practicality; • Ease of use; • Prevents accidents; • Greater durability • Low maintenance • High marketability potential; • A product of common necessity; • Industrial feasibility; • Security; State of the art: 7. In order to propose a novel and efficient solution, prior art searches were conducted in the INPI (National Institute of Industrial Property) database, and the following processes were found: 8.

ARTICULATED AND SLIDING SECURITY GATE. This patent application is aimed at the residential, commercial or industrial sector and is defined by a security gate that fits into the installation opening with its sliding section or division superimposed on the articulated section or division, aiming at its application in residences and / or properties in general. The fundamental objective of the gate is to protect mainly children, pets or any area delimitation for security, restriction or other reasons. The hinged and sliding security gate (1) consists of a frame (2) associated with a security lock (3) and two sections or divisions (4) and (5), the sliding division (4) being integrated into the hinged division (5) by means of double pulleys (6) coupled to internal guides (4.1) and (5.1) existing in both sections, with internal pulleys and guides at both the top and bottom of each section. The goal of the gate is to provide a versatile product for installation, ensuring maximum use of the passage opening and maintaining the proposed security, regardless of the gate's length. 11. As per the summaries above, the processes mentioned do not have any similarity to the object of this patent, which is why we consider that there are no technical or legal impediments to obtaining the requested privilege. 12.
