Description

DESCRIPTION TABLE STRUCTURE WHICH CAN EXPAND AND CONTROL ITS SURFACE Technical Field: The invention is related to a table structure that allows the surface areas of tables of different sizes to be expanded, which can be used in homes, workplaces, offices, schools, restaurants, cafes, canteens and similar areas. Known State of the Technique: In the known state of the technique, there are various mechanisms and structures that allow wide and narrow use of surface area in tables and similar structures used in homes, offices, restaurants, cafes, canteens and similar places. Conventionally used table surface expansion mechanisms generally consist of complex, difficult and multi-part structures. Simple structures are based on the use of table tops on top of each other, which will deform in a short time. Various bendings and deformations may occur on the table top surface due to the expanded table surfaces not being fully supported from below and strength weakness. The mechanisms used to expand the surface of a state-of-the-art table when needed are generally formed by bringing together multi-piece parts with high pre-production costs. The installation of multi-piece mechanisms requires high precision, and millimetric errors cause the mechanism to become inoperable. Its use can be complex and challenging for the end user. Extendable tables in the state of the art generally use a hybrid system, that is, the use of multiple materials. For example; It consists of multiple materials such as wood and metal combinations, glass and metal combinations. These materials react differently under physical environmental conditions. These different physical consequences deteriorate the mechanism over time and the product becomes unable to fulfill its function. Materials that expire quickly, are harmful to nature, and have high production and recycling costs are used in extendable table mechanisms. Chief among these are steel or galvanized steel profiles, steel ropes, numerous nuts and screws with special dimensions and features in the factory environment. In the extendable table structure used in the document numbered EP3346872, there are two interlocking carcass structures and the tables on them. However, in such a solution, the static load of the table structure is distributed unevenly on the table surfaces and legs. In addition, since the tables cannot be fixed to each other, deformations may occur on the surface during use. A complex mechanism is used in the extendable table structure used in the document numbered EP35 86674 and the two table surfaces are folded to adhere to each other. Due to the usage surfaces touching each other in the folded position, such solutions damage the table surfaces. There are folding table surfaces as well as many interlocking metal sliding channels. In this way, the lifespan of complex and multi-element solutions is short. Deformation occurs very quickly. In the document numbered US9675169, there is a seemingly simple yet relatively complex mechanism. In its closed state, the middle one of the three table surfaces is hidden under the other table surfaces. A complex metal rail and wheel structure was used to raise the table surface in the middle and obtain a wide surface. There are many different elements in the mechanisms used in the state-of-the-art extendable table structures and a lot of screwing equipment is used. This directly affects stability and creates a disadvantage for long-term use. Maintenance costs are increasing and maintenance and equipment renewal costs are increasing. As the number of table surfaces increases in extendable table structures, the stability of the table structure deteriorates and the usage time decreases. It is important that the table structure is light, has few parts, and provides a smooth and complete fixation. In addition to the number of table surfaces, pressure points may occur on the table surfaces due to constant loads and human use. These external loads on the table create additional force on the table surfaces and the connection elements between and below each table surface. These mechanisms used in current extendable table structures cannot work stably. Since the elements cannot fully fit into their slots when the table surfaces are opened, fixing cannot be done effectively and the tables and the loads they carry may be damaged. In addition, in state-of-the-art extendable table structures, there are many moving parts. For this reason, the adjustment and manufacture of state-of-the-art lock mechanisms are difficult and costly due to metal friction or wood friction movement. In existing systems, fixing elements cannot work efficiently. While table surface connection elements with completely different geometries and different numbers are working, fixing cannot be done because the elements cannot fit into their slots properly, or long-term stability cannot be ensured after being fixed. Unlike the extendable table structures in the known state of the art, a table structure (17) with a surface that can expand and contract, providing longer-term stability with fewer parts, is described. Purpose of the Invention: The invention is related to providing a wide usage area by increasing the surface areas of tables of different sizes. The invention consists of "Table Structure (17) whose Surface Can Expand and Contract", where at least one daughter table (4) remains hidden under the table (2) in the closed position, and in the open position, it opens side by side with the table (2), forming a fixed, adjacent and wide surface. table structure. It is intended to stabilize the extendable table structure stably in the open and closed positions and for long-term use. Dangerous deformations could occur in extendable table structures in the state of the art. Continuity could not be ensured in the use of extendable table structures, and long-term use was not possible. All elements in the mechanism of the extendable table structure, which can be used in many areas, can work together stably and the surface area of the extendable table structure can be easily adjusted. The aim of the invention with the invention is to create a simple and long-lasting system, structure and mechanism that can keep the mechanism elements placed between and under the tables more smoothly, without vibration and stable when the tables are in the open position. At the same time, a structure that allows easy and fast use is aimed. In this way, the tables can be opened and closed completely in an uninterrupted and synchronized manner. The aim of the invention is to ensure that the tables are connected to each other safely, to ensure the sliding movement of the tables without interruption, to have a low sound/noise level during opening and closing due to the use of few and compatible elements, and to keep the loads on the table surfaces without vibration. The invention aims to provide an alternative structure to extendable table mechanisms. Thanks to this alternative structure, a mechanical table top opening and closing mechanism suitable for mobile use has been developed, which is more stable, allows long-term use, can also be used with more tables, provides a smooth fixation even against higher loads. The aim is for the extendable table structure to be able to serve for a long time even if it is opened and closed very frequently, and to have a solid structure that does not cause any structural defects in the extendable table, tables or mechanism, and does not slip. It is aimed to prevent problems such as bending, tipping or falling that may occur due to the dysfunctionality of the connection systems in extendable table structures. The aim of the invention is to provide an alternative to complex and multi-piece connection systems between tables in extendable table structures and a solution containing fewer parts (elements). Thus, it is aimed to reduce maintenance costs and spare parts costs and to provide a more stable system with fewer elements/parts. Another purpose of the invention is to enable extendable tables to carry more internal and external load and to provide a stable opening/closing process without shaking. Especially in extreme usage areas such as portable extendable tables, a mechanism that can operate smoothly and stably is important. The aim of the invention is to create an extendable table that can function properly even in outdoor conditions and in a vehicle, like portable extendable tables. The aim of the invention is to reduce personnel and maintenance costs, ease the operation of the opening/closing mechanism, reduce costs, and enable additional loads to be added. Extendable tables in the state of the art do not work stably. The connection elements do not fit properly into their slots, and the wheel and gear systems may wear or corrode. Extendable tables can get stuck in the open or closed position and cannot be opened or closed at all. The stuck extendable table requires additional cost and overtime to repair or make it functional. Extending table mechanisms in the state of the art are exposed to a lot of friction and deformation due to their complex and multi-part structures. Due to their complex structure, their production is more costly. Due to the change in the amount of load on the tables in different positions, all elements and connections between the tables cannot work with the same stability or synchronization problems may occur. Since the tables sit hard when they are in place, wear occurs in the mechanism and elements due to impact and friction. Due to their complex structure, the mechanisms are difficult to adjust. These problems have been overcome with the invention. The aim of the invention is to reduce the use of many metal parts that increase product costs and are harmful to the environment through the production and recycling process. The invention has the advantages of previous techniques; It does not consist of complex, multi-part, rusting or broken parts that affect the product life and are difficult to repair. It is simple and useful. It is controlled by simple human movements. Modular production is easy. Production cost does not multiply the product cost. No extra prefabricated material is required when expanding the table surface size. In the state of the art, mechanisms that expand the table surface are available, as explained. However, the customization of existing table parts with the invention and a more useful, practical and robust structure was aimed and achieved with a new mechanism system. The aim of the invention is to open and close the table surface with simple movements when necessary and preferably use wood, a natural material, as the main material. With the invention, a cost-effective extension table structure mechanism that allows easy installation, easy use, is modular, can be produced quickly, provides ease of packaging and transportation, and is made of natural materials is aimed and presented. In the face of all these technical problems in the known state of the art, a new extendable table structure that is more stable, contains fewer parts and provides a firm grip has been explained with the invention. Another purpose of the invention is to enable the use of two or more daughter tables (4) in each table configuration, allowing the fixing and carrying performance to be more stable even if the number of tables is limited.

Table structure whose surface can expand and contract (table structure) Description of the Invention: The invention consists of "Table Structure (17) whose surface can expand and contract" where at least one daughter table (4) remains hidden under the table (2) in the closed position, side by side with the table (2) in the open position. It is an extendable table structure that forms a fixed, adjacent and wide surface. In the closed position, the table surface of the table configuration (17) has the narrowest structure. In the closed position, the table surface of the table configuration (17) consists of only the table (2) surface. In the open position, the child table (4) or child tables (4) combine with the table (2) to form a wide, monolithic table surface. The right and left side skirts (1) are located at the top of the table structure (17), on the sides, and are in the form of a skirt downwards from the surface. At least two side skirt middle stop pieces (16) in the middle of the right and left side skirts (1), which stop the closing movement of the table (2) by contacting the right and left table stop pieces (3) located under the table (2). The stop pieces (16) are preferably one in the middle part of the right side skirt (1) and one in the middle part of the left side skirt (1). However, the side skirt center stop parts (16) can also be in one piece, combined between the right and left side skirt (1). There is at least one side skirt outer stop piece (15) at the end of the right and left side skirts (1), which stops the opening movement of the table (2) by contacting the right and left table stop pieces (3) located under the table (2). The side skirt outer stop piece (15) is preferably a single piece, joined together between the right and left side skirt (1). However, it can also be found as one in the middle part of the right side skirt (1) and one in the middle part of the left side skirt (1). The side skirt outer stop piece (15) and the side skirt middle stop pieces (16) enable the table (2) to move without being separated from the frame and carcass of the table structure (17). The most important elements of the right and left side skirts (1) are the presence of sliding channels parallel to the ground, which are hollow on the inside, allowing the table (2) to slide back and forth through the teeth of the table (2). There are also parallel sliding channels on the inside of the right and left side skirts (1) and oblique sliding channels that meet at the end. Inclined sliding channels are in a structure that allows the daughter table (4) to be pulled up from the bottom or pushed down from the top on the inclined plane. The oblique sliding channels are in a structure where the teeth of the daughter table (4) will pass. After the child table (4) is pulled up, it is placed parallel to the ground at the level of the table surface, and the teeth of the child table (4) pass into the sliding channels parallel to the ground and are pushed towards the table (2) to merge with the table (2). In the same way, during the closing phase, the daughter table (4) is separated and removed from the table (2) through the sliding channels parallel to the ground, and when it reaches the tip, the teeth of the daughter table (4) are pushed downwards so that they pass into the inclined sliding channels. After the daughter table (4) reaches its position under the surface, the table (2) is brought to the middle part, to its closed position, by means of sliding channels parallel to the ground. Thus, the tray (2) covers the daughter tray (4). The sliding channels parallel to the ground and the oblique sliding channels of the right and left side skirts (l) are in the form of third channel structures that allow the movement of the table (2) and the daughter table (4). The right and left side skirts (l) ensure that the table structure (17) stands at a certain level, depending on at least four legs (9). There are side skirt support pieces (8, 10), preferably in pairs, at the ends of the right and left skirts (l). Side skirt support parts (8, 10) ensure increased strength, stability and balanced distribution of static load. The side skirt support parts (8, 10) combine with the top support parts (6) and increase the strength of the table structure (17). At the end parts of the right and left side skirts (l), behind the top skirts (7), there are at least two panels extending between the right and left side skirts (1), which ensure that the combination of the frame, right and left side skirts (1) and the foot (9) is secure. There are two top support parts (6). There are top skirts (7) just outside the top support pieces (6) on the extreme, outer parts of the right and left side skirts (l). The top skirts (7) extend between the right and left side skirts (1), one at each end. The top skirts (7) prevent the upper part of the table structure (17) from closing at the ends and prevent the elements and mechanism under and between the right and left side skirts (l) from being seen. The hill skirts (7) may have different aesthetic geometries and shapes. The channeled oblique miter piece (5) has a structure inclined downwards from the surface, between the right and left side skirts (1), at the end of the table structure (17). The slotted slanting miter piece (5) is fixed to the right and left side skirts (l) from the right and left sides. There are at least two sliding channels on it, through which the teeth under the baby tray (4) can pass and which enable the baby tray (4) to slide on it. The lower part of the channeled slanting miter piece (5) is L-shaped and prevents the baby table (4) from falling. In the closed position, the baby table (4) remains fixed on the inclined square piece (5). The channeled oblique miter piece (5) provides support for the frame and carcass of the table structure (17) to hold together and ensures smooth, uninterrupted movement of the daughter table (4) through the channel or channels on it. There is at least one retaining piece on the underside of the slotted slanting miter piece (5) towards the child table (4) to prevent the child table (4) from slipping in the closed position. This holding part may be in the form of a notch, in the form of a snap, in the form of a hook or in an L-shaped structure that holds the daughter tray (4) from the bottom. The table (2) is located at the top of the table structure (17), between and inside the right and left side skirts (1). On the right and left sides of the table (2), the right and left side skirts (1) have longitudinal teeth to fit into the sliding channels parallel to the ground. Thanks to the teeth opened on the edge of this table (2), it fits into the CNC channels of the right and left side skirts (1) and can move between closing and opening positions. There are at least two right and left table stop pieces (3) in the middle part of the table (2), at the bottom. These table stop parts (3) come into contact with the side skirt middle stop parts (16) during the closing phase, ensuring that the table (2) stops and is fixed. Likewise, during the opening phase, the table stop parts (3) contact the side skirt outer stop part (15) or its parts, ensuring that the table (2) stops and thus preventing the table (2) from separating from the frame of the table structure (17). The daughter table (4) enables the surface of the table structure (17) to expand. The daughter table (4) is invisible under the table (2) in the closed position. In the closed position, the baby table (4) rests steadily on the slotted miter piece (5) thanks to the L piece under the slotted miter piece (5). Under the baby table (4), there are at least two longitudinal teeth that fit into the sliding channel(s) of the channeled slanting miter piece (5). By means of these longitudinal teeth and the sliding channels of the inclined miter piece (5), the daughter table (4) slides back and forth on the inclined plane. There are longitudinal teeth on the right and left sides of the daughter table (4) to fit into the inclined sliding channels of the right and left side skirts (1). In this way, it can slide up and down in an oblique direction between the right and left side skirts (1). During the opening phase, after the table (2) is pulled to the end part, the open position, the daughter table (4) becomes visible. Thanks to the handle (12) located at the end of the child table (4), the child table (4) can be moved by human hands. The handle (12) may have different shapes and geometries. The handle (12) may be in the form of a hole or in the form of a handle extension fixed to the end of the daughter table (4), and may be made of metal, leather or other materials. The daughter table (4), which is held by the handle (12) and pulled up, is brought to the same plane as the table (2) after coming up. The daughter table (4) is placed on the same plane as the table (2); After moving to the plane parallel to the ground, the longitudinal teeth on the right and left sides of the daughter table (4) fit into the sliding channels of the right and left side skirts (l) parallel to the ground, and thus the daughter table (4) is pushed to the table (2) and merges with the table (2), forming a single piece. creates a surface. During the completion of this opening stage, the child table alignment part (ll) aligns the surface of the table (2) and the child table (4). The daughter table alignment piece (l 1) located at the inner end of the daughter table (4) has a structure that can fit into the table and clamp the child table (4) together with the table (2). Thus, in the open position, the surface of the table structure (17), that is, the monolithic, integrated surface consisting of the table (2) and the daughter table (4), is fixed in a solid and integrated structure. In the closing phase, the operations in the opening phase are performed in reverse. The daughter table (4) is separated from the table (2) by holding the handle (12), parallel to the ground, and brought to the end. Then, the baby table (4) is placed in the inclined sliding channels of the right and left side skirts (l). The baby table (4) is pushed downwards on the inclined plane on the inclined miter piece with channels (5) and between the inclined sliding channels of the right and left side skirts (l). It stops when it reaches the lower part of the slotted beveled miter piece (5), the L part. Finally, the table (2) is pushed to the middle part and brought to the starting position, and the entire surface is closed. The daughter tray (4) returns to its invisible position under the tray (2). The legs (9) are connected to the right and left side skirt parts (l) to carry the entire load of the table structure (17) and keep it fixed at the desired height. The legs (9) can be height-adjustable and telescopic. Thus, the surface of the table structure (17) allows use at different heights. The legs (9) are in L form or in a structure that can be connected to the right and left side skirts (1) in different shapes. The shoes (13) absorb the friction on the ground. There are at least four shoes (13), one on each foot (9). The shoes (13) may have a structure that allows fine height adjustment. Thus, slight balance problems that may arise from the floor and feet (9) are prevented. All elements are combined and fixed to each other with various connection elements (14). For example, it enables the mounting of L-shaped table legs (9) to the right and left side skirts (1) that form the frame of the table structure (17). Various screws, nails, allen head screws, knock-in nuts, various adhesive chemicals, set screws, bolts, hooks, squares, dowels, washers, locks, clips can be used as fasteners (14). The working principle of the invention is briefly as follows. Natural wood, which is preferably the main material of the table structure (17), and CNC channels (sliding channels, channels) located on the inside of the right and left side skirt parts (1) enable the tables (2, 4) to move. The table (2) is pushed towards the open position with a simple movement by means of the CNC channels and teeth located on the right and left side skirt parts (1). The right and left table stop parts (3) contact the side skirt outer stop part (15) and the forward movement of the upper table (2) stops. The channeled oblique miter piece (5), located under the top table (2) and mounted obliquely to the right and left side skirt pieces (1), serves as support for the right and left side skirt pieces (1) and ensures that the daughter table (4) is positioned on an inclined plane. It helps him move. There are slats that ensure smooth movement along the channeled inclined miter piece (5) under the child table (4) and prevent the child table (4) from being separated from the frame of the table structure (17). The daughter table (4) is pulled from the designated handle (12) with a simple hand movement and is brought to the same level as the upper table (2) by following the inclined channel path in the right and left side skirt parts (1). Then, it is combined with the top table (2) in parallel, placed in an adhesive position, and the surface of the table structure (17) is enlarged. In order for the table (2) and the daughter table (4) to remain balanced in the same alignment, the daughter table alignment piece (11) is mounted diagonally at the lower end of the daughter table (4). There may be a recess in the table (2) so that the child table alignment piece (11) on the child table (4) can pass or be mounted. While the table structure (17) is returned to its previous state (initial position, closed position), the movement of the daughter table (4) occurs in the reverse order of the opening stages. While the top table (2) is brought to the closed position, the table stop parts (3) overlap with the side skirt middle stop parts (16) and prevent the top table (2) from being separated from the table structure (17). The top table (2) has returned to its previous position (initial position, closed position). It is a table structure (17) with a surface that can expand and contract, and its feature is; - a daughter table in the form of a cavity on the inner side where the daughter table (4) is located, which contains channels in the form of cavities on the inner side where the table (2) is located and enables the table (2) to slide forward/backward on the table structure (17) parallel to the ground, in a direction parallel to the ground. (4) to the right and left side skirts (1), which have oblique channels that enable them to slide, - to the outer side skirts (1), which contain protruding teeth on the right and left side, in a way to pass into the channels of the right and left side skirts (1). It contains right and left table stop parts (3) that are fixed to the table (2) in a close position and move together with the table (2) and can slide forward/backward in a parallel direction to the ground on the table structure (17) and inside the side skirts (1) and thus - to the table (2), which enables the expansion of the table surface, - to the side skirt outer stop piece (15) at the bottom of the table (2), which is mounted on the table (2) in a position outside, that is, close to the side skirts (1), and moves with the table (2) during the opening phase. ) to the right and left table stop parts (3), which enable the table (2) to stop by contacting, and to the side skirt middle stop parts (16) in the closing phase, which ensure the table (2) to stop by contacting, the table structure (17) under the table (2) when it is in the closed position. , right and left, containing at least two longitudinal teeth at the bottom of the side skirts (1), located on the obliquely shaped baby table carrying piece (17) and the channeled oblique miter piece (5), to fit into the channels of the channeled oblique miter piece (5). Next to it, the daughter table alignment piece (11), which includes longitudinal protruding teeth to fit into the channels of the right and left side skirts (1), contains at least one handle (12) at the upper end to hold and move it, and provides a balanced connection with the table (2). ), containing the table structure (17), after the table (2) is brought to the open position, it is pulled up and out by sliding it on the channeled slanted miter piece (5) by holding the handle (12), and then it is brought to the same level and adjacent position with the table (2) by pushing it parallel to the ground. , when the table structure (17) is in the open position, it is adjacent to the table (2) and provides a large monolithic table surface, when the table structure (17) is closed, it is pulled outward parallel to the ground along the channels of the side skirts (1) by holding the handle (12), and then the channeled oblique miter The daughter table (4), which is brought to the initial position by pushing it obliquely downwards on the part (5) and along the inclined channels of the side skirts (1), is placed on the daughter table (4), which contains at least two sliding channels on the upper part to pass over the teeth of the daughter table (4). It carries the daughter table (4) on it by ensuring smooth movement, has a holder part at the bottom to prevent the daughter table (4) from sliding in the closed position, is fixed obliquely to the side skirts (1), and thus ensures that the table structure (17) remains stable together. The channeled inclined miter piece (5) that provides support for the table structure (17) and the right and left table stop pieces (3) during the opening phase of at least four tables (2) that ensure that the table structure (17) stands at the desired height, contact the right and left table stop pieces (3) to stop the table (2).
