Description

1 TARIFF CONFERENCE LEG, WELDED TO THE CHAIR LEG, AVAILABLE FOR BOTH RIGHT AND LEFT SIDES. ARM SYSTEM TECHNICAL FIELD The invention relates to conference and training chairs used in the furniture industry, in particular. tablets that add writing tablet functionality to chairs, welded to the chair leg and positioned on the right or left. It relates to a viable conference arm system. 10 STATE OF THE ART Today, educational institutions use conference and seminar halls, meeting rooms, etc. The chairs used allow the user to write, take notes, or hold various materials. 15 conference arm systems that include a writing tablet for placement on them is used. In current applications, the aforementioned conference arm and writing tablet They are usually designed together with the chair, and the armrests are attached to the chair body or shell. or is attached to the side carcass structure. In standard practices, the conference arm is attached to the chair frame or side frame. The shaping of the armrests makes them dependent on the chair model in which they will be used. For example, two chairs with different body geometries or connection points. In most cases, it is not possible to directly use the same conference arm in this model. And a suitable mounting structure needs to be created separately for each chair model. This 25 This situation leads to an increase in part variety, more complex production processes, and different parts. This leads to the need for stockpiling. However, in current systems, conference arms for right and left-handed use are separate. They may need to be designed in structures. For example, a writing tablet for right-handed use should be 30 One user wants it on the right side of the chair, while another wants it on the left. It may be necessary to provide different arm groups for the user. This situation is within the manufacturer's control. and requires the manufacturer and stock of different products or parts for left-hand use, order This also makes it difficult to change the direction of use afterwards. 35 The conference arm is attached to the chair using detachable fasteners such as clamps, bolts, brackets, etc. In applications to which it is connected, repetitive loads occur during use. 2 Due to this, loosening may occur at the connection points over time. The issue is that loosening of the conference arm can cause play, movement, jerking, or creaking. This is possible in applications where the conference arm is directly attached to the chair shell. this is because the loads applied by the user to the typepad are concentrated on the shell. The risk of deformation, cracking, or loss of shape is 5, especially in relatively thin shells. It is located. Another shortcoming of the current practices is that the chairs initially lacked a conference armrest. The difficulty lies in later converting it into a conference chair. The conference chair Because it requires model-specific body or frame connections, previously purchased 10 Adding a conference arm to an already purchased chair is not always practical. Therefore, if a conference chair is needed later, the existing chair should be used. It may be necessary to replace or provide a new conference chair with armrests. Additionally... The legs that form the base of the chair; height, length, and where welding can be applied. They can have different geometries in terms of surface area and the number of twists they possess. 15 For example, a shorter, single-bend leg positioned near the center of a chair base. While one foot may be found, the other may be longer and have more than one bend. This Geometric differences mean that a uniform conference arm connection structure can be attached to different legs and different This makes it difficult to apply to chair designs. In the known state of the art, application number US201213450635 “Adjustable tablet” The patent application titled "chair" is for both right-handed and left-handed users. A chair suitable for individuals, featuring a writing tablet. The chair has a writing tablet mounted on an armrest. It includes a writing tablet. The writing tablet arm is located under the seat element of the chair. It has a rotatable mechanism, so it can be positioned on either the user's right or left side. 25 The writing tablet is hinged to the writing tablet arm, so the writing tablet sits securely in place. The writing tablet can rotate towards or away from the person. The writing tablet can also be rotated on the writing tablet arm. It is mounted in a movable way, so the writing tablet moves towards and away from the person sitting. It can move away. The seat of the chair, the chair legs, and "preferably mounted hinged to a support structure that includes wheels" is stated as 30 This document is being prepared on a writing tablet that can be adapted for both right-handed and left-handed users. It relates to the chair. The writing tablet is supported by a tablet arm; the tablet arm is attached to the chair. It passes under the seat and rotates into the chair support structure. It is attached. By turning the arm from one side to the other, the writing tablet is attached to the chair. It can be used on the right or left. Also, the table can be positioned towards or away from the user. It can be moved and rotated a distance. However, US201213450635 The documentation states that the conference arm in our invention has a pivot mechanism under the chair. 3 Instead of moving it from right to left along the armrest tube, the armrest tube moves along the chair base. It is not explained why one of their feet is directly welded from the source area. In our invention, right or left-handed use is achieved by welding the arm tube to the leg on the respective side. The length and number of bends of the arm tube are also determined according to the geometry of the chair leg. When replacing it, the other arm components can be left unchanged. 5 In another known instance of the art, application number US390304, "With a writing tablet" The patent application entitled “chair” consists of “a seat (14), a backrest (16) and a first a device that can move between a lowered non-working position and an elevated working position. A chair with a base structure (12) carrying a writing tablet (38). First lowered work 10 In the external position, the writing tablet (38) is parallel to a vertical axis and the chair is longitudinal It is inclined with respect to a vertical plane parallel to its axis, so that two or more of the same type The chair is positioned lengthwise so that the writing tablets of two adjacent chairs partially overlap. They can be brought closer together. The writing tablet (38) is also tilted with respect to a vertical axis. and that it is inclined relative to a vertical plane parallel to the longitudinal axis of the chair 15 It also has a second lowered non-working position, so that two or more of the same type can be used. The chairs are positioned vertically so that the writing tablets of two adjacent chairs partially overlap. It is stated as "can be stacked on top of each other". According to the structure described in this document. The lower section of one of the rods in the chair's support structure forms the chair leg, and the upper section... This forms the armrest support. The writing tablet is located on a 20-inch section at the top of this bar. It is connected to the joint mechanism. Although the table is shown on the right side in the document, It is stated that it can also be placed on the left side without significant changes to the structure. However, In our invention, the supporting arm tube of the conference arm forms the continuation of the chair leg. It is not attached to the top of a special supporting structure that brings it; the existing chair It is later joined to the foot at the base by welding. This structure is also suitable for 25 This allows existing chairs to be later converted into conference chairs with armrests. In the current state of technology, the need for separate designs for right and left-handed use depends on the chair model. Dependence, loosening of connection points over time, loads on the chair shell transferring, the difficulty of adding conference chairs to existing chairs later, and the different 30 problems such as inability to adapt to chair leg geometries It is seen. In conclusion, the existence of the above problems and the inadequacy of the current solutions are related to the technical aspects. This has made it necessary to make improvements in the field. 35 4 THE PURPOSE OF THE INVENTION The present invention meets the aforementioned requirements while eliminating all disadvantages. The right / left welded attachment to the chair leg provides a lift and offers some additional advantages. It relates to the conference arm system. 5 The purpose of the invention is to move the arm tube carrying the conference arm away from the chair body or shell. directly welded to one of the legs forming the base of the chair thanks to its rigid structure, it allows the loads generated during use to be transferred to the chair base. and to establish a robust conference arm system. 10 Another purpose of the invention is to use the same conference arm system on either the right or left side of the chair. enabling its application to the foot, separate conference arm structures for right and left-handed use. The goal is to reduce the need for production and stockpiling. Another purpose of the invention is to adjust the length of the arm tube and the number of bends at the connection. Thanks to the fact that it can be determined according to the geometry of the chair leg to be used, the conference the arm system can be adapted to different leg geometries and different chair models to provide. Another purpose of the invention is to utilize what has been previously produced or used without a conference arm. by enabling the addition of conference arms to the suitable chairs provided. The aim is to enable existing chairs to be converted into conference chairs with armrests. Another aim of the invention is to make the connector head, mounting plate and writing tablet detachable. 25 By bringing them together with connectors, assembly processes are facilitated and, if necessary... changing the writing tablet without interfering with other components of the conference arm to provide opportunities. The structural and characteristic features and all the advantages of the invention are given in the figures below and these 30 The detailed explanation, written with references to figures, makes it clearer.
