GRADUAL LOAD TRANSFER, IMPACT LIMITATION, AND VERSATILITY. TRAVEL SUITCASE WITH MECHANICAL PROTECTION MECHANISM

Abstract

The invention relates to a travel suitcase with a stepped load transfer, impact limitation, and multi-directional mechanical protection system designed to control and distribute the effects of impact, vibration, pulling, pushing, deflection, and overload experienced by the suitcase during use via the wheels and handle to the load-bearing areas of the suitcase body. Within the scope of the invention, mechanical loads originating from the wheels are met in the first operating stage via a movable load transfer structure. As the mechanical load increases, the resulting relative movement causes a mechanical stage transition, activating the second load-bearing stage. When the relative movement reaches a defined operating limit, mechanical limitation is applied. Any subsequent overload is then directed to the main load-bearing structure, reducing overload concentration in sensitive connection areas.Mechanical loads transmitted from the wheels and the pull handle are correlated within a common mechanical load-transfer structure and distributed across the wider load-bearing areas of the suitcase body in both transverse and longitudinal directions. By directing mechanical forces from different directions into controlled movement paths and guiding movable structures within permissible limits, multifaceted mechanical protection is ensured. This results in a mechanical travel suitcase structure that passively adapts to changing mechanical load conditions without the need for electronic sensing or control, providing incremental load handling, overload guidance, and integrated load distribution.

Within this scope, the invention relates solely to the damping of vibration or shock originating from wheels. Unlike structures where the load is distributed gradually among mechanical elements; transfer, mechanical interaction of additional load-bearing elements under increasing load. As a result, it participates in load carrying, and when the limit of movement is reached, the mechanical 30 termination is carried out and the ongoing overload is transferred through the load-bearing structure. Mechanical load management systems in which distribution functions are performed together. It includes technology. 2 State of the Art: Today, travel suitcases are designed to protect and store the belongings being transported and to provide comfort for the user. Different body, wheel and tow hook options to ensure easy transport. They are manufactured with handle structures. Commonly used wheeled travel suitcases Multiple wheel sets in the lower or bottom corner areas of the suitcase body, top or rear 5 In this section, there are fixed parts that allow the suitcase to be pulled, pushed, and steered. or it has a telescopic pull handle. In common designs, wheel assemblies are usually located at the bottom or corner of the suitcase body. directly to the regions or via intermediate connections such as wheel carriers and mounting brackets. It is connected via its elements. The suitcase is suitable for uneven surfaces, thresholds, and pavements. passing over edges, steps, gaps and similar surface irregularities sudden vertical, horizontal or oblique movements of the wheels during transport, and impacts. Ground reaction forces are transmitted to the suitcase body via the wheel attachment points. This can be communicated. This is especially true under usage conditions when the suitcase is loaded. The effects are felt in the wheel links, linkage sockets and the load-bearing 15 of the body. This can cause repetitive or sudden mechanical stresses in these areas. In the current state of technology, vibrations and shocks from the wheels affect the suitcase. Elastic elements, springs, and flexible wheel structures are used to reduce the transmission of energy to the body. and mechanical arrangements such as suspension systems can be used. In such solutions... The basic approach is that the impact acting on the wheel results in elastic deformation or limited movement. 20 This is due to the damping effect to a certain extent. However, this only applies to the impact. In damping-based structures, increasing mechanical load is reduced by successive different loads. transfer between support levels, mechanical interaction of additional load-bearing elements As a result, the load becomes involved in transportation and the overload is redirected to a different carrier route in a controlled manner. There are areas open to improvement in terms of how it is directed. 25 In typical travel suitcases, the pull handle generally allows the user to pull the suitcase. It is arranged as a separate support structure that enables it to push and steer. Telescopic pull arms feature interlocking profiles, guide elements, and different mechanisms. Locking mechanisms that provide fixation in extended positions can be used. The pulling, pushing, and reversing forces applied by the user to the pull handle constitute pulling force 30. mechanical stress is created in the areas where the handle is attached to the suitcase body, The forces resulting from the interaction of the wheels with the ground affect other parts of the suitcase. The signal is transmitted to the body via the wheel connections. 3 A sudden change of direction, one of the wheels hitting an obstacle, or the suitcase moving suddenly. stopping or applying force to the handle in a direction different from the suitcase's direction of movement In situations such as these, the suitcase can be attached via the pull handle and wheel connections. The body can be subjected to mechanical loads of varying magnitudes and directions. Tensile This is because the arm and wheel groups are connected to different parts of the body. The forces are met at independent connection points, distributing the mechanical loads. This can lead to concentrations in specific connection areas. In the known state of the art, the movement of the telescopic pull handle is due to the wheels. additional mechanical features such as moving it between usage or storage positions There are also solutions where these are used in functions. However, such structures are 10 mainly the positioning of the wheels or the way the suitcase is used It is designed to change the mechanical loads coming from the wheels and the drawbar. being accommodated within a common load-bearing structure, functionally compatible with each other and gradual integration of the fuselage into larger load-bearing areas. Its distribution may be limited. 15 In addition, travel suitcases have electronic control units and location tracking features. systems, user or identity recognition devices, sensors, electric locking systems, energy sources, motorized motion devices, and various electronic aids Applications where these hardware components are used are also known. These systems are predominantly... as well as the security, traceability, user interaction or movement of the suitcase 20 It is aimed at increasing its capabilities. However, these types of electronic functions its location, the mechanical system transmitted to the suitcase body via the wheel sets and the pull handle loads are met at different operating levels and overload is controlled. It alone does not meet the structural need related to transferring resources to carrier regions. In existing mechanical structures, shock absorption caused by wheels, pull handle 25 guiding or restricting movement and the structural design of specific connection areas Strengthening them can be done separately. However, normally Meeting the service loads at the primary mechanical load-carrying stage, increasing secondary load-bearing stage as a result of relative movement caused by mechanical load. mechanical engagement, a mechanical limitation of the ongoing movement 30 excessive control by the system and continuing after the movement limit is reached transfer of the load to larger load-bearing areas via an additional carrier link There are areas that can be improved in this regard. 4 Selecting a single elastic element with higher rigidity allows the connection areas to be only structurally thickened or wheel connections made completely rigid The introduction of different magnitudes and directions of mechanical loads allows for different operational performance. It may not be able to manage things according to its own conditions on its own. It is too flexible. While the connection can negatively affect the steering and carrying stability of the suitcase, a high 5 A rigid connection causes sudden impact loads to be transferred directly to the body. This is possible. Therefore, different mechanical elements require different load conditions. a phased work characteristic that allows it to participate in transportation is needed It is located. In addition, shock absorption is implemented only at the wheel connections, pull handle 10 the pulling, pushing and deflection forces occurring through it to the suitcase body It does not change the method of transfer. Similarly, only the pull handle Strengthening the connections also reduces impact and ground reaction from the wheels. It does not provide for the management of the forces. Therefore, the wheel sets and traction mechanical loads taken from the arm are combined with each other within a common load-bearing architecture. functionally related and the distribution of the loads across the length and width of the suitcase body a technical need to distribute them to wider carrier regions along their lines It is located. Therefore, in the known state of the art; the normal handling and transport of the suitcase during normal use and while maintaining steering stability, 20 different strands coming from the wheel groups and the drawbar. capable of directing mechanical loads of varying directions and magnitudes to controlled load-bearing elements. capable of meeting normal operating loads at the primary mechanical load-bearing level, Additional load resistance resulting from relative motion caused by increased mechanical load. capable of mechanically engaging its elements, with defined ongoing relative motion. capable of terminating at the limit of mechanical movement and continuing after that limit of movement. 25 able to transfer the excess load to the wider load-bearing areas of the suitcase body An integrated and multi-stage mechanical load management system is needed. The purpose of the invention: The primary purpose of the invention is to enable the pulling, pushing, steering, and lifting of a travel suitcase. and during transport on different surfaces, it is powered by wheel sets and a pull handle 30 The varying mechanical loads of different directions and magnitudes occurring within the limited space of the suitcase body reducing the concentration of these loads at numerous connection points, suitcases directs the load to the load-bearing elements within it and depending on the changing load conditions an integrated mechanical load system that activates different mechanical load handling levels The goal is to develop a system of governance. Another objective of the invention is to reduce mechanical loads that occur under normal operating conditions. the primary load-bearing stage is used to meet the increasing mechanical load. As a result of the relative movement it brings, the secondary load of the mechanical step transition element is 5 mechanically engaging the receiving stage and thus the load-carrying task between multiple load-bearing elements depending on varying mechanical load conditions The aim is to ensure that it is shared gradually. Another objective of the invention is to have primary and secondary load-carrying stages follow each other. By enabling it to engage during mechanical operating ranges, it allows for low and normal 10 maintaining the stability of the suitcase during transport and orientation under varying loads, increased load and in sudden impact conditions, additional load-bearing elements transfer the load. The goal is to create a stepped mechanical operating characteristic that allows for its participation. Another purpose of the invention is to eliminate surface irregularities, sills, and gaps in wheels.

Another objective of the invention is to create a 20-degree gap between load-transmission elements under increasing mechanical load. If the relative motion that occurs reaches the defined motion limit, the mechanical system... the mechanical interaction between the limiting element and the limiting counter element by allowing it to enter, uncontrolled displacement of the movable load transmission elements and to limit the excessive mechanical stresses associated with it. Another objective of the invention is to extend the permissible range of motion of the stepped load transfer system to 25 Finally, creating a mechanical termination and continuing after the limit of movement in question. The overload is transferred via the overload routing connection with the final load transfer element. directing the main load to the load-bearing frame, thus reducing overload at sensitive connection points. to reduce the concentration of the load and distribute the load to wider load-bearing areas The goal is to ensure its transfer. 30 Another purpose of the invention is to reduce impact and ground reaction caused by wheel sets.

Another objective of the invention is to transmit mechanical loads to a common mechanical load transfer carrier. The suitcase body can handle larger loads through its longitudinal and transverse load distribution elements. by transferring it to the carrier areas at the wheel and drive handle connections. to reduce local stress and load concentrations that may occur and the aforementioned repeated mechanical stresses at the connection points affect a larger load-bearing structure. The goal is to ensure its spread. Another purpose of the invention is to protect the suitcase from the vertical, horizontal and 10-degree impacts it may be subjected to during use.

During transportation over surfaces, the wheel groups and the pull handle are used incoming mechanical loads on the limited number of attachment points of the suitcase body to reduce concentration, mechanical loads of different magnitudes and directions following each other 5 managing the load handling stages, relative to the load that occurs under increasing load. mechanically restricting movement and the continued overload on the suitcase body Gradual load transfer developed to direct loads to larger load-bearing areas, It is a travel suitcase with impact limitation and multi-directional mechanical protection mechanisms (1). Travel suitcase (1), the items to be carried are placed in and the basic outer structure of the suitcase 10 the suitcase body (2) and the mechanical load-carrying capacity of the suitcase body (2) It includes the supporting main load-bearing frame (3). The main load-bearing frame (3), Mechanical loads from the wheel sets (5) and the pull handle (26) are only on the suitcase Instead of meeting the local connection points of the body (2), the mechanical common mechanical load transfer carrier (31) and load distribution elements of the loads 15 allows for its orientation along a broader, interconnected load-bearing structure. It is mechanically connected to the suitcase body (2) in such a way as to provide. Main load-bearing frame (3), coming from the wheel sets (5) and the drawbar (26). mechanical loads are met only at the local connection points of the suitcase body (2) instead, the common mechanical load transfer carrier (31) of the mechanical loads in question, transverse load 20 with distribution element (32), longitudinal load distribution element (33) and load distribution plate (4) allows for its orientation along a broader, interconnected load-bearing structure. It is mechanically connected to the suitcase body (2) in such a way as to provide. between the main load-bearing frame (3) and the suitcase body (2) or the main load-bearing There is at least one load distribution plate (4) in the load-bearing areas of the frame (3). 25 Load distribution plate (4), mechanical load taken from a point or narrow connection area It is designed to allow the forces to be spread over a wider surface. Load distribution plate (4) can be placed in the lower area, rear area, corner areas or of the suitcase body (2). the connection where load concentration may occur in the main load-bearing frame (3) It can be located in the regions. The load distribution plate (4) can be in one piece 30 It can also be implemented in multiple plate forms in different load transfer zones, such as those mentioned. Travel suitcase (1) is the most suitable suitcase body (2) for moving on the ground. It has at least one wheel group (5). Wheel group (5) has at least one wheel (6), wheel (6) wheel carrier (7) and the carrier of the wheel carrier (7) in the suitcase It includes the wheel mounting housing (8) which enables it to be associated with the structure. The wheel (6) will allow the suitcase to move in a linear or multi-directional manner. It can be attached to the wheel carrier (7). The wheel carrier (7) allows the wheel (6) to rotate. while supporting its movement, it also transmits shock, vibration and 5 from the ground to the wheel (6). carrier that enables the transmission of ground reaction forces to the stepped load transfer system. It forms the intermediate structure. The wheel mounting bracket (8) is only rigid to the wheel carrier (7) and the suitcase body (2). instead of connecting via a link, the mechanical loads from the wheel (6) 10 that will allow it to be transmitted to a controlled load transfer system It is structured. The wheel mounting bracket (8) is located at the bottom or lower corner of the suitcase body (2). It can be located in the region and the main load-bearing frame (3), load distribution plate (4) or in connection with load-bearing elements that are mechanically related to these It can be edited. Wheel load transfer between wheel carrier (7) and stepped load transfer system 15 There is a connection (9). The wheel load transfer connection (9) is from the wheel (6) and mechanical effects with vertical, horizontal or inclined components from the wheel carrier (7) It ensures that the load is transmitted to the movable load transmission element (10). Wheel load transmission connection (9), direct connection, articulated connection, pin connection, guided connection or an equivalent mechanical system that allows the load to be transferred in a specified direction. 20 This can be done in the form of a connection. The effect of mechanical load from the wheel assembly (5) on the movable load transmission element (10). limited relative movement under the suitcase body (2) and the main load-bearing frame (3) It is arranged in such a way as to perform the movable load transfer element (10). The relative movement it performs corresponds to 25 different load handling levels of the system, respectively. It constitutes one of the fundamental mechanical movements that enables it to engage. The relative motion of the movable load transfer element (10) is linear, curvilinear, rotational or a combination of these; amount and direction of movement This is kept under control through guidance structures. Controlled movement of the movable load transfer element (10) by at least one guiding element 30 (11) and guidance mechanically matched with the said guidance element (11) is provided via its socket (12). 11 The guiding element (11) is on or with the movable load transfer element (10). While it can be created on a connected part, the guide housing (12) wheel connection on the housing (8), main load-bearing frame (3) or a fixed load-bearing structure associated with them It can be created in this way. The reverse arrangement can also be applied. The mechanical relationship between the guiding element (11) and the guiding housing (12) is the movable 5 uncontrolled displacement of the load transfer element (10) under the effect of the load to limit and ensure the operation of the load-carrying stages of the element in question. It ensures that progress is made in the necessary direction. Under normal operating conditions, the mechanical load transferred from the wheel assembly (5) is first The primary load is met by the load-bearing element (13). Primary load-bearing 10 element (13) is mechanically related to the movable load transfer element (10) the load from the wheel group (5) must be met in the first working stage It provides. Primary load-bearing element (13) is capable of performing controlled movement under load or a carrier element that, working in conjunction with an elastic element, manages the movement in question 15 It can be created in this way. At least one primary elastic element (14) associated with the primary load-bearing element (13) The primary elastic element (14) is located. to withstand low to medium-sized mechanical loads and sudden wheel-related shocks It contributes to the controlled reduction of mechanical effects. 20 Primary elastic element (14); compression spring, tension spring, torsion spring, elastomeric element, elastic buffer, leaf spring or mechanical energy storage and recovery capability It can be realized in an equivalent structural form. The working principle of the invention is specific. It is not limited to the type of elastic element. Controlled compression, elongation or decompression of the primary elastic element (14) under load as shown in Figure 25 There is a primary bearing surface (15) for changing it. Primary bearing surface (15) on which at least one side of the primary elastic element (14) rests and in the elastic element mechanical surface that enables the transfer of the resulting reaction force to the supporting structure It constitutes. Primary bearing surface (15), main load-bearing frame (3), wheel mounting housing (8), 30 on the load distribution plate (4) or a fixed mechanical element connected with it can be created. 12 Mechanical load from the wheel (6) under normal operating conditions; wheel carrier (7), via wheel load transfer linkage (9) and movable load transfer element (10) The load is transferred to the primary load-bearing element (13). As a result of the controlled deformation of the primary elastic element (14), the system first operation It withstands the mechanical load in question at this stage, and the movable load transfer element is 5. (10), movement determined by the guiding element (11) and the guiding housing (12) It performs a limited relative movement in that direction. Relative movement of the movable load transfer element (10) in case of increase in mechanical load is ongoing and the system is moving from the first load handling stage to the second load handling stage. It transitions mechanically to the next level. 10 In order to ensure that this transition is carried out in a controlled manner, the system has mechanical components. There are step transition elements (16). The mechanical step transition element (16) is movable. As a result of the load transfer element (10) reaching the determined relative position, the secondary load in order to enable the reception staff (19) to participate in the load carrying It is structured. 15 on or mechanically connected with the mechanical step transition element (16) There is at least one transition protrusion (17) in the region. Transition protrusion (17) is a moving load during the movement of the transmission element (10) in the first working stage, the transition correspondence It can be located at a certain distance from the surface (18) and the continuation of the said relative motion By doing so, it approaches the transition counter surface (18). 20 In this way, the activation of the second load handling stage is achieved through electronic load sensing. or without electronic control operation, transition projection (17) with transition correspondence through the mechanical positions and relative movements of the surfaces (18) relative to each other It can be accomplished. The transition counter surface (18) occurs under increasing mechanical load of the transition protrusion (17) 25 It is the surface that the incoming relative motion comes into contact with or mechanically interacts with. The initial distance between the transition projection (17) and the transition counter surface (18) is geometric. location and contact type, from first load handling level to second load handling The transition to the next level can be structured in a way that determines the working characteristics. The distance and geometric relationship in question is the carrying capacity of the travel suitcase (1), wheel 30 according to the structure of the group (5) and the desired mechanical response characteristic It can be differentiated. 13 Mechanical interaction of the transition projection (17) with the transition counter surface (18) As a result, the secondary load-carrying element (19) participates in load transfer. Transition By establishing a contact or bearing relationship between the protrusion (17) and the transition counter surface (18), resulting from the continuous relative motion of the movable load transfer element (10) At least part of the force is transmitted to the secondary load-bearing element (19). Thus, 5 secondary load-bearing element (19), only works continuously simultaneously with the first stage. Rather than being a support element, the mechanical step transition element (16) is determined An additional load-carrying vehicle joins the load-carrying task after reaching its relative position. It constitutes a level. The secondary load-bearing element (19) is separate from the primary load-bearing element (13) or 10 This can be realized in the form of a load-bearing structure mechanically connected to it, and It constitutes the second stage of operation in meeting the increasing mechanical loads. At least one secondary elastic element (20) associated with the secondary load-bearing element (19) The secondary elastic element (20) is activated in the second operating stage. increasing mechanical element (14) together with or following the primary elastic element (15) It contributes to meeting the burden. Stiffness, range of motion, geometry or elastic characteristic of the secondary elastic element (20) The primary elastic element (14) can be selected differently. Thus, the system can be a single elastic element. different mechanical load ranges without being bound by the constant operating characteristics of the element It can generate different mechanical response characteristics. 20 In order for the secondary elastic element (20) to generate counterforce, the secondary bearing surface (21) is located. The secondary bearing surface (21) is one end of the secondary elastic element (20). or the response that occurs in the second operating stage, on which the load-bearing region is based. It forms the surface that allows the force to be transferred to the load-bearing structure. Secondary bearing surface (21), main load-bearing frame (3), load distribution plate (4), 25 on the wheel mounting socket (8) or one of the fixed support elements of the system can be created. In this way, the primary elastic element (14) is weighted under normal operating conditions of the system. while receiving the load, the increase in mechanical load and the movable load transfer element (10) As a result of reaching the determined relative position, the mechanical step transition element (16), transition 30 Secondary load bearing element (19) via its protrusion (17) and transition mating surface (18) and secondary elastic element (20) participate in load carrying. 14 Thus, the increase in mechanical load is a continuous process occurring in a single elastic element. Instead of being met with deformation, it withstands successive mechanical loads. It is distributed among the levels. If the increasing mechanical load continues, the relative load transfer element (10) of the moving load transfer element to ensure that its movement is kept within safe mechanical limits, at least one mechanical element 5 There are limiting (22). Mechanical limiter (22), movable load transfer element (10), mechanical step transition element (16), secondary load bearing element (19) or a movable structure connected with them It can be created on it. Limiting counter element 10 to work in conjunction with the mechanical limiting (22). (23) is located. Limiting counter element (23), main load bearing frame (3), wheel mounting housing (8), load distribution plate (4) or other fixed support structures It can be positioned on one of them. Mechanical limiter (22) and limiter counter element (23), normal and second The movable 15 units are located at a certain distance from each other during their working intervals. to the maximum allowed relative movement position of the load transfer element (10) As they approach each other, they come into mechanical contact. Contact between mechanical limiter (22) and limiter counter element (23), moving load limiting the uncontrolled progression of the transmission element (10) and the primary outside the permitted operating range of the elastic element (14) and the secondary elastic element (20) This helps prevent excessive deformation. This mechanical contact can be in the form of direct rigid contact, or it can involve the effect of an impact. an intermediate buffer, elastomeric contact zone, or equivalent mechanical layer that helps reduce pressure. It can also be done via a contact structure. At the end of the permitted range of motion of the stepped load transfer system, the mechanical load is 25 to prevent it from remaining only on elastic elements and movable joints There is a final load transfer element (24). The last load transfer element (24), after reaching the mechanical limiting stage structural elements with higher load-carrying capacity to withstand ongoing high mechanical loads. It is being organized in a way that will enable its transfer to the regions. 30 The final load transfer element (24) transfers the main load via the overload routing link (25). It is mechanically related to the supporting frame (3). Overload guide link (25), the permitted operating range of the moving system The mechanical load that continues after reaching the end of the wheel mounting housing (8), primary elastic element (14), secondary elastic element (20) or limited of suitcase body (2) instead of concentrating on one region, the main load-bearing frame (3) It allows for its redirection. 5 Main load via the last load transfer element (24) and overload routing link (25) The mechanical load transmitted to the carrier frame (3) is terminated in the main load carrier frame (3). not required, common mechanical load transfer carrier (31), transverse load distribution element (32), longitudinal load distribution element (33), body load transfer connection (34) and load distribution 10 from plate (4) to the wider carrier areas of the suitcase body (2) It can be distributed. Thus, the load transfer path that is activated in case of overload, not only the protection of the moving mechanism, but also the mechanical load in question on the suitcase It also enables its transfer to an integrated load-bearing architecture. Overload routing link (25), final load transfer element (24) and main load carrier direct mechanical contact, support, locking, articulated connection between frame (3) 15 or in the form of an equivalent mechanical relationship that comes into play under load It can be accomplished. Thus, the system includes primary load bearing, secondary load bearing, and mechanical restraint. and final load transfer as successive mechanical operating stages is being carried out. 20 Within the scope of the invention, there is a definite force for the activation of these work stages. Electronic measurement of its value is not mandatory. Transition between levels; movable load transfer element (10), mechanical step transition element (16), transition its protrusion (17), transition counter surface (18), mechanical limiter (22) and Geometric positions of the limiting counter element (23) relative to each other and mechanical 25 This can be achieved through relative movements occurring under load. transition from the first load handling level to the second load handling level within the scope Instead of relying directly on measuring a specific force value, it relies on the effect of mechanical load. the relative motion occurring underneath reaching a predetermined geometric position This can be done depending on the situation. Similarly, mechanical restraint and final load 30 The stages of transmission are also determined by the mechanical properties of the moving elements relative to each other. They can be activated sequentially as a result of reaching certain locations. Thus, different implementation of load management stages, geometric arrangement of mechanical elements, and 16 passive mechanical work determined by relative motion occurring under load It forms the sequence. This structure is suitable for travel suitcases (1) where there is no power source or electronic control. even under these conditions, it is possible to perform basic load management functions. It provides. 5 In addition to the mechanical loads caused by the wheels (6) in the travel suitcase (1), the pull handle (26) while the user pulls, pushes and steers the suitcase It is also envisioned that the resulting mechanical loads will be managed. The pull handle (26) can be grasped by the user and moves the travel suitcase (1). This can be achieved with a fixed or telescopic arm structure that enables it to be moved. 10 The pull handle (26) can only be connected to the suitcase body (2) via limited connection points. instead of being connected to the load-bearing structure via the pull arm carrier (27) It is connected. The pull handle carrier (27) handles the pull, push and redirection from the pull handle (26). will reduce the concentration of forces in a narrow area of ​​the suitcase body (2) and the word 15 The subject matter is designed to transmit forces to the load transfer structure. The mechanical placement of the pull handle carrier (27) in the suitcase body pull handle connection is provided via its socket (28). The pull handle mounting socket (28) is for fixing the pull handle (26) or telescopic Mechanical load transfer of the pull handle carrier (27) with the structure that enables its movement 20 They can be created in a way that supports both functions. Transmission of mechanical forces originating from the pull arm (26) to the common load-bearing structure For this purpose, there is a pull handle load transfer element (29). The pull arm load transfer element (29) receives the pull, push from the pull arm carrier (27). and deflection forces to the common mechanical load transfer carrier (31) 25 It directs. The pull handle load transfer element (29) is located at the bottom, side or rear of the pull handle carrier (27). It can be attached to this area and allows the load to be transferred to the carrier structure of the suitcase. in the form of a profile, connector, arm, plate or equivalent mechanical structure It can be accomplished. 30 Under the mechanical load effect of the pull handle (26) and the pull handle carrier (27) Pull handle guidance to reduce uncontrolled lateral movement. There are (30) elements. 17 The pull arm guide element (30) allows the movement of the pull arm carrier (27). While maintaining their orientation, the mechanical load of the pull arm load transfer element (29) is shared It helps to transmit the mechanical load to the load transfer carrier (31) in a controlled manner. Common mechanical load transfer carrier (31), integrated mechanical load management of the invention It is one of the important components of its structure. 5 Common mechanical load transfer carrier (31), mechanical from wheel groups (5) the loads and mechanical loads that occur through the pull handle (26) of the suitcase This allows for its association with the common load-bearing structure within the organization. Mechanical loads from the wheel groups (5) affect the operation of the stepped load transfer system. Depending on the situation, the wheel load transmission linkage (9), movable load transmission element 10 (10), primary load bearing element (13), secondary load bearing element (19), final load main load carrier via transmission element (24) and overload guide link (25) to the frame (3) and the common mechanical load transfer carrier mechanically associated with it (31) can be directed. Mechanical loads from the pull handle (26) are directed from the pull handle. carrier (27), pull handle load transfer element (29) and common mechanical load transfer 15 It is associated with the same carrier architecture via its carrier (31). Thus, the wheel The suitcase features graduated load management on one side and load transfer on the pull handle side. not as two separate load-carrying systems independent of each other, but as a common carrier (2) of the body The architecture can function as different load-bearing zones. In this way, the mechanical loads caused by the wheel groups (5) and the pull handle (26) are separated from each other by 20 instead of terminating at completely independent and limited fuselage connections, common mechanical with the same structural carrier architecture via load transfer carrier (31) can be associated. Common mechanical load transfer carrier (31), different load input without requiring the concentration of mechanical loads from different regions at a single point, 25 It creates a mechanical intermediate support structure that enables wheels and traction. The loads originating from the handle are independent of the different and limited connection areas of the suitcase body (2). Instead of terminating them as separate loads, these loads are routed within a common load-bearing architecture. and distribution is ensured. The common mechanical load transfer carrier (31) can be connected directly or indirectly to the main load carrier frame (3) 30 transverse load distribution element (32), longitudinal load distribution element (33), body load transfer mechanically via the connection (34) and load distribution plate (4) They can be associated. 18 The geometry of the common mechanical load transfer carrier (31) is based on the dimensions of the travel suitcase (1). and depending on the load-bearing capacity, profiles, plates, frames, crossbars or a combination thereof. It can be realized in the form of a structure consisting of a combination of elements. The transverse load distribution element (32) is taken from the common mechanical load transfer carrier (31). mechanical load on multiple carrier zones in the width direction of the suitcase body (2) 5 It contributes to its distribution. Thus, especially if one of the wheels (6) of the suitcase is subjected to a sudden impact or The mechanical load that occurs when a lateral force is applied to the pull handle (26) is the single The concentration of energy in a single connection area can be reduced. Longitudinal load distribution element (33) 10 taken from common mechanical load transfer carrier (31) the distribution of mechanical loads along the longitudinal direction of the suitcase body (2) It provides. Longitudinal load distribution element (33), lower wheel connection areas and upper or rear traction a load-bearing profile or equivalent structural element extending between the arm connection points It can be done in the form of different cargo entry zones of the travel suitcase (1) 15 It establishes mechanical continuity between them. The transverse load distribution element (32) and the longitudinal load distribution element (33) are connected to each other. can be directly connected, intersecting or common mechanical load transfer carrier (31) with the main It can establish an indirect mechanical relationship through the load-bearing frame (3). The transverse load distribution element (32) and the longitudinal load distribution element (33) together form 20 The use of mechanical loads coming from different directions only on the suitcase body (2) It allows distribution not in a single direction, but in multiple carrier directions. It provides. Mechanical from the transverse load distribution element (32) and the longitudinal load distribution element (33) At least one body 25 for the purpose of transferring the loads to the carrier areas of the suitcase body (2). There is a load transfer link (34). Body load transfer connection (34), main load carrier frame (3), load distribution plate (4), suitcase with transverse load distribution element (32) or longitudinal load distribution element (33) It forms a mechanical connection between the load-bearing region (2) of its body. Body load transfer connection (34), connecting elements, mechanical fittings, riveted 30 connections, bolted connections, structurally integrated areas or equivalent mechanical connections It can be carried out in various forms. 19 The basic function of the body load transfer linkage (34) is to distribute mechanical loads within the system. the load into the larger areas of the suitcase body (2) that have sufficient carrying capacity The aim is to ensure that the transfer is carried out in a controlled manner. The mechanical effect from the wheel group (5) occurs in only one direction. because it does not arrive, there is at least one pulse guiding element in the system (35) 5 It can be found. Impact guiding element (35) as a result of an impact with vertical, horizontal or oblique components. the mechanical effect transmitted to the movable load transmission element (10) is allowed by the system It contributes to directing movement in the right directions. Impact guiding element (35), inclined contact surface, guided connection, hinged 10 at least one of the carrier or equivalent mechanical steering geometries It may include. Thus the wheel (6) moves not only in the vertical direction, but also in the movement of the travel suitcase (1). Depending on the orientation, mechanical loads acting in the horizontal or inclined direction are also gradual. It is possible to transmit the load to the load transfer system in a controlled manner. 15 Multi-directional with or independently of the pulse guiding element (35) Mechanical guide (36) can be used. The versatile mechanical guide (36) is used to guide the movable load transmission element (10) or wheel limited movement allowed under mechanical effects from different directions of the carrier (7) It is structured in such a way as to allow it to move in those directions. 20 Versatile mechanical guide (36), linear guide surfaces, curved guides, articulated joints or mechanical guides allowing for multiple directions of movement It can be formed from a combination of its geometries. The use of the versatile mechanical guide (36) makes it possible to keep the travel suitcase (1) uneven. During movement on surfaces, the wheel group receives 25 from different directions (5). mechanical impacts directly on the wheel mounting housing (8) or suitcase body (2) It helps to reduce uncontrolled transmission. The versatile mechanical guide (36) eliminates mechanical load instead of mechanical load It controls the direction and limits of the movement that occurs under its influence. Mechanical functions of the impact guiding element (35) and the multi-directional mechanical guide (36) 30 They are different from each other, yet they complement each other. It can be realized. The impact guiding element (35) receives impacts coming from different directions. mechanical effect suitable motion components for the operation of the stepped load transfer system while contributing to its guidance, the versatile mechanical guide (36) Permissible directions of relative movement resulting from orientation and ensures that it is kept within the limits of movement. Thus, different directional mechanical directing the effect and guiding the movement that results from that effect. 5 as complementary mechanical functions that follow each other or operate simultaneously It can be accomplished. Contributing to the determination of the safe operating limits of the stepped load transfer system. There are mechanical termination elements (37). Mechanical end element (37), movable load transfer element (10), wheel of the carrier (7), mechanical step transition element (16) or load transfer system 10 beyond the maximum permissible mechanical range of another moving part It can be positioned in a way that will prevent it from passing through. Mechanical termination element (37), mechanical limiter (22) and limiter counterpart supporting the limiting function formed by the element (23) or this A safety element 15 that forms the final limit of movement after the restraint phase. This can be realized as follows. In this way, the mechanical limiter (22) and the limiter The counter element (23) controls the working movement of the system, while the mechanical termination element (37) ultimate physical movement limit under overload or unusual impact conditions It can create. The work formed by the mechanical limiter (22) and the limiter counter element (23) 20 The final physical limit formed by the boundary and the mechanical termination element (37) is different from each other. It can be performed in different relative motion positions. Thus, the first limitation... During this phase, while maintaining the controlled operating range of the load transfer system, unusual situations occur. A second physical level of safety under impact or overload conditions. This can be created. This stepped restraint structure allows for the transfer of moving loads. 25 mechanical working limits of the element (10) or related moving parts Furthermore, it reduces uncontrolled displacement. Main load-bearing frame (3), load distribution plate (4), common mechanical load transfer carrier (31), transverse load distribution element (32), longitudinal load distribution element (33) or body load At least one reinforcement in the high load bearing junction areas of the transmission link (34) 30 The connecting element (38) can be used. 21 Reinforcement connecting element (38) connects the load transfer system to the suitcase body (2) and the mechanical to increase its integrity and prevent formations in connection areas under repeated loads It is designed to reduce potential local deformations. Reinforcement connecting element (38), corner reinforcement, connecting plate, profile part, mechanical in the form of a connecting leg or equivalent structural support element 5 It can be accomplished. The location and number of the reinforcement fastener (38), the size of the travel suitcase (1), the transport Its capacity can be changed according to the geometry of the main load-bearing frame (3). In the working principle of the invention, the travel suitcase (1) moves on a normal surface. Mechanical loads caused by the wheels (6) while being driven; wheel carrier (7), 10 via wheel load transfer linkage (9) and movable load transfer element (10) The primary load is transmitted to the load-carrying element (13). The primary elastic element (14) works together with the primary bearing surface (15) to achieve the following: It withstands mechanical loads at the first operating stage. Meanwhile, the movable load transfer element (10), the guiding element (11) and the guiding element 15 Limited relative motion in the direction of motion determined by its housing (12). is able to accomplish this. The wheel (6) encounters a threshold, gap, step, surface irregularity or similar obstacle. If the mechanical load increases as a result of this encounter, the movable load transmission element (10) relative movement is increasing. 20 When the movement reaches the determined geometric position, the mechanical step transition element (16) The transition protrusion (17) on it mechanically interacts with the transition counter surface (18). and the secondary load-carrying element (19) participates in load transfer. In the second stage of operation, the secondary elastic element (20) and the secondary bearing surface (21) By working together, they contribute to meeting the increasing mechanical load. 25 The primary elastic element (14) can continue to carry the load at this stage, as well as the application Depending on its shape, the greater part of the mechanical load is on the secondary elastic element (20) can be met by. Thus, the system exhibits varying total mechanical stiffness and motion across different load ranges. It can exhibit this characteristic. 30 Further increase in mechanical load and the permitted limit of the movable load transfer element (10) If the working movement approaches its end, the mechanical limiter (22) It makes mechanical contact with the corresponding element (23). 22 The contact movable load transfer element (10) has more uncontrolled movement. limiting its operation and the primary elastic element (14) and the secondary elastic element (20) It helps prevent it from being subjected to excessive deformation. If the excessive mechanical load continues even after the mechanical restraint phase mechanical load, final load transfer element (24) and overload guide link (25) 5 The load is transferred from the main load-bearing frame (3) to the main load-bearing frame. Main load-bearing frame (3), load distribution plate (4) receives the mechanical load, common mechanical load transfer carrier (31), transverse load distribution element (32), longitudinal load distribution element (33), body load transfer connection (34) and, if necessary, reinforcement connection element (38) It can distribute the loads over the wider carrier areas of the suitcase body (2). 10 If the user applies a pulling or pushing force to the pull handle (26) mechanical load; pull handle carrier (27), pull handle connection socket (28) and pull handle through the load transfer element (29) to the common mechanical load transfer carrier (31) It is being transmitted. The pull handle guide element (30) is at the time of the pull handle carrier (27) allowed 15 It maintains its mechanical position and is uncontrolled, especially under lateral or oblique forces. It reduces displacement. Common mechanical load transfer carrier (31), mechanical loads taken from the pull arm (26) mechanical loads transmitted from the wheel groups (5) to the carrier structure are carried in the same structural manner. It enables management within the system. 20 Thus, the wheel connections and the pull handle connections are attached to the suitcase body (2) Instead of mechanical load termination in completely independent and limited regions, the mechanical loads in question are common mechanical load transfer carrier (31), main load carrier frame (3), transverse load distribution element (32), longitudinal load distribution element (33), body load The suitcase body (2) can be further 25 via the transfer link (34) and load distribution plate (4). It can be transferred to large carrier areas. When the travel suitcase (1) changes direction or one of the wheels (6) is tilted, it is subjected to impact. when exposed to impact guiding element (35) and multi-directional mechanical guide (36), directing the resulting relative motion in the directions allowed by the system It is helpful. 30 This mechanical guidance results in the gradual distribution of mechanical loads coming from different directions. the load is transmitted to the load-bearing structure and the movement is within the defined mechanical limits. It is ensured that it is kept in place. 23 An unusually large impact, a sudden jamming of the wheel (6) or the travel suitcase (1) mechanical situations such as the sudden cessation of movement under high mechanical load The termination element (37) constitutes the final physical movement limit of the system. Thus, the separation of the moving parts from the guide housing (12) is elastic. Exceeding the working limits of the components or uncontrolled placement of load-bearing parts 5 Its ability to change can be restricted. In the invention, the mechanical properties of the primary elastic element (14) and the secondary elastic element (20) They don't have to be the same. Primary elastic element (14), low and medium sized mechanical in normal use secondary elastic 10 to have a mechanical rigidity suitable for withstanding the effects element (20) is different, suitable for meeting higher magnitude mechanical loads. It can be implemented in a way that provides a certain mechanical rigidity. Conversely, it is also possible to use elastic elements with variable characteristics. Thus, travel suitcases (1) can be different depending on their intended use and carrying capacity. Step-by-step load characteristics can be created. 15 initial distance between transition projection (17) and transition counter surface (18) by changing the secondary load bearing element (19) to participate in load bearing relative motion Its location can be determined. This geometric arrangement can be determined as a fixed feature during production, or... Adjustable in certain applications if suitable mechanical adjustment elements are used. 20 It can also be carried out in a qualitative manner. However, the basic operating principle of the system is from the first operational level to the second. the relative transition projection (17) of the transition counter surface (18) of the transition level It is based on being realized as a result of their mechanical positions. In one application, each wheel group (5) has its own movable load transmission 25 element (10), primary load bearing element (13), primary elastic element (14), mechanical Step transition element (16), secondary load bearing element (19), secondary elastic element (20) can have a mechanical limiter (22) and a final load transfer element (24). In another application, the mechanical loads of more than one wheel group (5) It can be transmitted to a common staged load transfer module. Thus, the invention allows two, four 30 or applicable to travel suitcases with different numbers of wheel sets (5). 24 In one application, the main load-bearing frame (3) is the circumferential carrier of the suitcase body (2). in a closed or partially closed frame structure extending throughout its regions It can be accomplished. In another application form, the main load-bearing frame (3) with wheel mounting areas longitudinal support profiles extending between the pull handle connection area and the 5 It can consist of transverse load-bearing elements that connect the components. In both cases, the main function of the main load-bearing frame (3) is to transfer mechanical loads to the suitcase. instead of terminating its body at (2) limited connection points, a wider carrier The goal is to ensure its transfer to the structure. Load distribution plate (4), transverse load distribution element (32), longitudinal load distribution element 10 (33) and reinforcing connecting element (38); metal, polymer, fiber reinforced composite or other structural materials that provide mechanical strength suitable for the operating conditions It can be produced. Similarly, the main load-bearing frame (3) is made of lightweight metal alloy, structural polymer, It can be made from composite profiles or a combination thereof. 15 are used. The types of materials used do not alter the fundamental mechanical working principle of the invention. Movable load transfer element (10), mechanical step transition element (16), final load transfer element (24), pull handle load transfer element (29) and common mechanical load transfer carrier (31) by single piece or by combining multiple mechanical parts can be created. 20 The geometries of the elements in question are based on the dimensions, carrying capacity of the travel suitcase (1), depending on the arrangement of the wheel groups (5) and the desired load transfer characteristic It can be changed. The invention's stepped operating characteristic requires only two elastic elements to be used in series or parallel. It is not based on being used in this way. 25 Mechanical step transition element (16), transition projection (17) and transition counter surface (18) thanks to the secondary load bearing element (19) determined relative load bearing process They are enabled to participate after the movement. Therefore, the first and second working stages must be mechanically separated from each other. and as the mechanical load increases, the secondary load-bearing element (19) participates in load bearing 30 It is possible. Similarly, mechanical limiter (22), limiter counter element (23), final load transmission element (24), overload guide link (25) and mechanical termination When element (37) is evaluated together, the system is only a shock absorbing structure It is becoming less than normal load; increased load, limited high load and overload. a multi-stage mechanical load in which different mechanical elements are involved under these conditions It establishes a system of governance. The mechanical load management structure of the invention is 5 electronic systems in the travel suitcase (1) This does not prevent its discovery. Travel suitcase (1), electronic locking, positioning in different applications, communication, user recognition or similar assistive systems It is available for use. However, the invention includes primary load handling, mechanical step transition, and secondary load 10. basic functions of handling, mechanical restraint and overload guidance The working principle depends on the presence of electronic systems or an electronic device. It is not dependent on the control command. Thanks to this feature, the system can detect if there is no power source in the travel suitcase (1), the electronic unit is disabled or the suitcase is a completely mechanical product 15 It also fulfills basic mechanical protection functions in the applications where it is implemented. It can bring. If electronic assistance systems are available, these systems will be phased in. It can provide additional functionality to the mechanical load transfer system; however, stepped load It is not necessary to establish the basic mechanical working sequence of the transmission system. 20 Within the scope of the invention, wheel assembly (5), wheel carrier (7), mobile load transmission element (10), guiding element (11), guiding housing (12), primary load bearing element (13), primary elastic element (14), mechanical step transition element (16), secondary load bearing element (19), secondary elastic element (20), mechanical limiter (22), end Load transfer element (24) and related mechanical elements can be disassembled or 25 It can also be implemented in the form of a customizable module. In such an application, the stepped load transfer module can accommodate different sizes or transport requirements. It can be adapted to suitcase bodies (2) with capacity. Similarly, common mechanical load transfer carrier (31), transverse load distribution element (32), longitudinal load distribution element (33) and main load-bearing frame (3), suitcase body (2) 30 It can be formed integrated with the suitcase body (2) during production or later It can also be implemented in the form of separate, assembled carrier parts. 26 These different production methods are related to the invention's wheel sets (5) and pull handle (26) the principle of managing mechanical loads coming from it within a common load-bearing architecture It does not change anything. As a result, the mechanical load taken from the wheel assembly (5) in the invention is primary in the first stage. The load is met by means of the load-bearing element (13) and the primary elastic element (14); increasing 5 Mechanical step transition as a result of relative motion caused by mechanical load. secondary load through element (16), transition projection (17) and transition counter surface (18) It involves the counter-load element (19) and the secondary elastic element (20) in load transfer. If the relative motion continues, the mechanical limiter (22) and the limiting counteracting element (23) restricts movement; under further overload conditions, the final load transfer 10 element (24) with overload guide connection (25) mechanical load main load carrier It directs to the frame (3). At the same time, mechanical loads resulting from the pull handle (26); pull handle carrier (27), pull handle connection socket (28), pull handle load transfer element (29) and from the common mechanical load transfer carrier (31) to the main load carrier frame (3) 15 is being transferred. Mechanical loads from the wheel groups (5) and the pull handle (26); common mechanical load transfer carrier (31), transverse load distribution element (32), longitudinal load distribution element (33), The suitcase body can be loaded by means of the body load transfer link (34) and load distribution plate (4) (2) is distributed to wider carrier regions. 20 The impact guiding element (35) and the multi-directional mechanical guide (36) are from different directions. while ensuring that incoming mechanical forces are directed into the permitted directions of movement, The mechanical termination element (37) constitutes the final physical movement limit of the system. and reinforcement connection element (38) in high load bearing structural connection areas It supports the mechanical integrity of the system. 25 Thanks to this integrated structure, it can handle primary load, secondary load, and mechanical functions. Step switching, mechanical limiting, overload guidance, multi-directional motion control. and transverse and longitudinal load distribution functions follow each other and are mechanically interconnected. This is achieved through related structural elements. Thus, the mechanical 30 to which the travel suitcase (1) is subjected under different usage conditions concentration of loads on a single connection area or a single elastic element The mechanical load is reduced and gradual, directed and controlled within the suitcase. A transfer structure is being created. 27 Industrial Application of the Invention: The invention utilizes existing body, wheels, pull handle, and components used in the manufacture of travel suitcases.
