AN ENHANCED RELAX MECHANISM FOR FURNITURE.

Abstract

This invention relates to a relaxation mechanism with increased rigidity that allows the backrest of furniture such as armchairs and sofas to be moved to expand the seating area. The invention includes a frame connection metal (3) fixed to the fixed frame of the furniture, a backrest connection L metal (6) connected to the movable back frame, and a straight bar (4) and V bar (5) that transmit motion between them. The basis of the invention is that the backrest connection L metal (6) has a special geometry containing at least one bend. Thanks to this bent geometry, when the mechanism is brought to the upright seat position, it is hidden in the inner space between the frame and the back frames, preventing the formation of dead spaces on the furniture, ensuring aesthetic integrity and maximum seating width. In addition, the mechanism has an architecture that can be fixed directly to the frame structure with a total of only 8 M8 nuts (1) and washers (2) without the need for external connection plates.

1 TARIFF AN ENHANCED RELAX MECHANISM FOR FURNITURE. TECHNICAL AREA 5 This invention is beneficial to the furniture industry, particularly for armchairs, sofas, and similar seating groups. The invention relates to back movement mechanisms used in furniture. Specifically, it concerns... without creating any loss of usable space (dead space) in the seating position, preserving visual integrity and its integrated connection profiles (pipe 10 with a relax mechanism that increases structural rigidity / strength thanks to profiles It is related. STATE OF THE ART In conventional technology, the seating area in furniture such as armchairs and sofas is made functional. to expand and provide users with a more comfortable sitting / reclining position tilting the spine backward or downward to present a (relaxed position) moving, somersaulting on the back, or operating with similar kinematic principles mechanisms are used. 20 However, these existing mechanisms, their structural geometries, and operational dynamics... there are many technical disadvantages both in the production and end-use phases. This brings with it the most prominent technical aspects of the aforementioned existing systems. One of the problems is that when the back is brought to an upright (normal sitting) position, 25 due to the kinematic arrangement of the mechanism or the volume of the housing "Dead spaces" that cannot be effectively utilized are created on the furniture. This is what it means. These dead spaces directly affect the seat width of the furniture. restricting the usable space the user can obtain from the cushion surface. It narrows. 30 However, during back movement, the furniture extends beyond its outer contours. Overflows are occurring, which is altering the back and the overall product form of the furniture. It disrupts aesthetic integrity and visual continuity. The most common problem in current practices is... 2 The critical mechanical weakness lies in the mechanism sets located on the right and left sides of the furniture. The two are mounted onto the frame completely independently and separately from each other. a direct structural stabilization bridge between the mechanical arms on the sides or Because there is no rigid connecting element, when a load is applied to one side of the system, or Over time, due to usage, asymmetrical contractions may occur during movement and 5 Synchronization losses are occurring. This lack of structural integrity, premature wear and structural deformations at the joint points of the mechanism, and even leading to permanent damage to the main wood / metal frame of the furniture. It opens. Finally, the mechanisms in the known technique are complex and have exposed connections. Due to their geometries, concealing these mechanical parts during production, flooring to prevent it from getting caught in the fabric or to prevent contact with the user extra stitching, custom lining / fabric cuts, and challenging upholstery These applications are needed. This significantly increases assembly times. By extending it, it leads to optimization problems in mass production lines and labor costs. It increases costs. DEFINITION OF INVENTION This invention overcomes the disadvantages of the current state of the aforementioned technology. In order to eliminate rigidity, the rigidity of furniture (chairs, sofas, etc.) is increased. A relax mechanism with enhanced structural integrity and improved visual defects. It aims to present. A key purpose of the invention is to allow the mechanism to be concealed between the chassis back frames. Thanks to the curved backrest connection structure (L metal), the backrest is in the seat position. The goal is to completely eliminate the "dead areas" that have formed. This way, the product form and aesthetics are improved. without compromising integrity, the session (font) width is maximized. User comfort and usable space are increased. 30 One of the most important mechanical purposes of the invention is to connect the right and left sides. by connecting the mechanism components to each other using at least one tubular profile 3 The aim is to provide integrated rigidity to the system. This pipe profile, especially 10 By choosing a wall thickness of mm, between the right and left arms of the mechanism A bridge of complete synchronization and strength is established. In this way, a single Asymmetric contractions, joint wear, and even unilateral loading can occur. By preventing deformations, the service life of the mechanism and furniture frame is extended to 5 years. It is significantly extended. Another purpose of the invention is the extra stitching to conceal the mechanism. The aim is to eliminate labor and complex installation processes. The mechanism Thanks to its compact design integrated between the frames, the flooring processes are 10 This makes things easier, reduces labor costs, and minimizes the margin of error. One of the ultimate goals of the invention is to achieve optimization in the production and assembly line. The developed mechanism structure eliminates the need for extra complex connecting parts. Without even realizing it, it can be easily attached to the furniture frame with just 8 M8 nuts. It can be fixed in place. This shortens assembly times, greatly facilitating mass production. It provides speed and efficiency. Explaining the Figures: The invention will be described by reference to the attached figures, so that the invention Its features will be understood more clearly.

Rivet Metal. 5 DETAILED EXPLANATION OF THE INVENTION The invention concerns a relaxation mechanism with increased rigidity for furniture, essentially a chair. and in seating furniture such as sofas, the backrest can be moved backward and downward 10 by moving the seating area (font) along a correct kinematic path It is a mechanical system that allows for its in-depth expansion. This system ensures structural integrity during and after movement. While protecting without the need for an external connecting profile, it incorporates 15 elements into the interior design of the furniture. It has a component geometry that prevents the formation of dead space. (Figure 1) The perspective view of the M8 nut (1) and the connecting washer (2) given in Figure 2, all the movable and fixed components of the mechanism are connected to each other or to the furniture These are the main locking elements used to secure it to the body. (Figure 3) The shown frame connecting metal (3) is attached to the fixed bottom frame of the furniture or to the carrier 20 the base plate rigidly fixed to the body with a bolt / nut combination It forms the flat bar (4) in Figure 4 and the V-shaped bar (5) in Figure 5. the shearing and angling movement of the mechanism, on which carrier that provides force transmission through positioned bearing holes They are arms. 25 The back connection L metal (6), the details of which are shown in Figure 6, is the volumetric and structural component of the invention. It is one of the most critical parts that provides an advantage. This back connection L metal (6), not progressing in a linear plane but containing at least one bend (offset) It has a special geometry. This twisted form allows the part to withstand torsional and bending forces. by providing high sectional strength (inertia) against moments the mechanism remaining rigid within itself without an external profile supports. The rivet metal (7) given in Figure 7 is flat bar (4), V bar (5), casing. 6 joint points between connecting metal (3) and back connecting L metal (6) by creating a controlled rotation of the parts relative to each other. It enables (him to lie down). Figures 8, 9 and 10 show the mechanism in its assembled state and the frame on which it is attached. Their positions are shown from different angles. The mechanism is symmetrical on the right and left. The blocks achieve a kinematically stable equilibrium when connected to the skeletal structure. They form the system. Damping of asymmetric loads and rigidity integrity; chassis riveting of connecting metal (3), flat bar (4), V bar (5) and back connecting L metal (6) They are geometrically connected to each other at multiple points by means of metals (7) 10 This is achieved by locking. The components of the mechanism, especially under load, are axial. Constructed with wall thicknesses to prevent warping, it is applied to the furniture on one side only. when weight is applied or an asymmetrical force is applied to the user's back area The mechanical stresses that occur when applied directly to the lamellae (4, 5) and twisted The back connection L metal (6) absorbs 15 through its own body strengths. It enables it to be done. In the dynamic operation of the mechanism, a force is applied backward to the back region. When applied, the back joint L metal (6) receives this force and is connected in an articulated manner. It starts a rotational movement on the straight lamella (4) with the V lamella (5). V lamella 20 (5), supported by the fixed joint point on the case connecting metal (3). While guiding the shearing motion, the straight blade (4) ensures the linear stability of the motion. It protects. During this kinematic cycle, the back connection L metal (6) is bent (Offset) structure, so that the back skeleton does not hit the dead spaces behind the body or without aesthetically unpleasing protrusions to the outside, directly onto the frame and back skeleton 25 It is hidden in the inner space between the legs, allowing it to slide downwards. This keeps the back straight. Even when the (seat) is returned to its original position, it puts pressure on the upholstery behind the cushion. or no "dead space" remains that creates gaps; font (session) space is maximized. This is achieved by expanding productivity. As shown in Figures 9 and 10, the mechanism is attached to the main frame of the furniture. integration optimized to reduce labor errors on the production line to zero. It has been made. The back connection L metal (6) and the case connection metal (3) are located on it. 7 Mounting sockets require no external complex brackets or connecting plates. It is designed so that it will not be audible. The entire system has surface-mounted connection points. Guided by connecting washers (2) that distribute the pressure homogeneously, in total only It is fixed to the frame structure with 8 M8 nuts (1). This compact and 8 The nut-based fastening architecture allows the mechanism to contact the upholstery fabric. 5 allowed to be embedded inside the skeleton in a way that would prevent it from causing erosion. This allows for the addition of extra stitching and lining to conceal the fabric during production. It completely eliminates their labor costs. 15 25
