    DESCRIPTION

    Retention system for joints.

    Object of the invention 5

    The object of the present invention is to provide a simple retention system, to make joints between profiles without using welding, screws, or any other additional element or accessory.
     10
    The system that is recommended, is of general application in the sector of construction, furniture, children's games, etc.

    Background in the state of the art
     fifteen
    In recent years, the use of structural tubular profiles has increased based on the numerous advantages they have over traditional open profiles, especially in lattice-like structures. Thus, the structural advantages of this type of profiles are especially evident when they are going to work under compression or torsion.
     twenty
    Additionally, one of the reasons that takes greater weight in the use of tubular profiles is aesthetics, by providing cleaner and more slender structures, being able to have profiles with the same exterior appearance, but with very different mechanical properties.

    However, and despite the generalization of its use, this type of profiles has a great inconvenience when using them and is the greatest difficulty in resolving their joints. Thus, these joints are usually solved by welding or using additional accessories, both solutions being very expensive and inefficient. In contrast to these, the present invention provides a solution that substantially simplifies the union between profiles and significantly improves the efficiency and manufacturing and assembly costs of any frame, frame or structure.

    Based on the inventions that make up the state of the art, identified, by their publication number and title, respectively:

    However, the "Joint retention system" proposed with the present invention provides the following advantages with respect to the state of the art;

    1. Avoid welded or bolted joints that involve greater cost, complexity and runtime.
     twenty
    2. It avoids the use of any additional element or accessory to make the union, making use exclusively of the profiles to be joined.

    3. It allows a solid, resistant and irreversible joint, unlike the current joining systems by means of fittings that require, once a piece 25 is slid over the other, to fix said joint by welding or other mechanical means, since, otherwise, this union could be released in the same way it was done.

    4. Unlike welded joints, it allows disassembly, by incorporating a tool that consists of a simple folded sheet, easy to manufacture and very economical, with which we can release the joint without the profiles suffering damage or deterioration.

    5. It is not conditional on the type of profile used, whether open or closed: quadrangular, rectangular or even circular, or the type of material: metallic, plastic, etc.

    6. The execution of the tabs and grooves on the profiles themselves can be executed using any cutting or machining technology available in the market: laser, plasma, chip removal, 3D printing, etc. 40

    7. The union is carried out in a simple and completely manual way without the need to use tools, nor undertake prior deformation on any of the elements involved in said union, the blocking position being clearly identifiable acoustically and visually, which simplifies the process of assembly Four. Five

    Explanation of the invention.

    By way of explanation of the "Retention system for joints", consisting of a locking and locking mechanism that uses only the elements object of the joint, providing them with a flange-groove configuration without any additional material or element, according to dimensions of the flange and its corresponding groove that ensures that the flange fits inside the groove in a final locking position.

    Thus, the aforementioned locking and locking mechanism on which the invention is based, can be presented in any combination as regards the total number of flange-groove configurations containing the joint, the relative position between the elements to be joined, variations in terms of the shape, position or angle of the tabs themselves, or of the grooves, the latter may be or in the form of slits, notches or even grooves, 5 the configuration of different flange-groove games being compatible in the same Union.

    Continuing with the description, the locking and locking mechanism can be based on the following configuration;
     10
    1. An element (A) provided with an insertion gap of dimensions similar to the external dimensions of the element (B), as well as one or more tabs, which are located on the upper horizontal face of said element (A), adjacent to the insertion hole, and each of said tabs being the result of making two longitudinal cuts so that the space between the two cuts delimits the area of said flange.

    2. An element (B) that has to fit in the aforementioned socket of the element (A) and which, only, must have one or more grooves in its lateral faces, in number, position and dimension such that All tabs are housed in their corresponding grooves at the precise moment of joining.

    By way of clarification, the description of the previous invention is extended to any possible configuration between two or more elements to be joined using the flange-groove configuration, particularly as regards the section of each of them, being able to be the same or different, including or not a socket of any depth, and the union can be made at any angle and location, even at the ends of said elements.

    For the correct functioning of the system, the dimensions of the tabs will depend on the dimensions and thicknesses of both profiles, and on the location of their corresponding grooves. For its part, each slot must be long enough for the flange to fit into it without gaps and narrow enough, so that, when fitted, the tab rests on the bottom and top edges of the groove stably. If the groove were too wide, the flange could be introduced through the groove, causing the system 35 not to function properly.

    Likewise, it is important to highlight how the actions to be carried out on both profiles (A-B) in the terms described, are carried out by means of simple cuts, emptied or mechanized and without incorporating any additional element. 40

    From the profiles described, in order to carry out the connection between them as a joining procedure, it would be sufficient to manually slide the element (B) into the insertion hole of the element (A), causing the corresponding tabs to be flex as both elements approach each other, until at the end of the path through the hollow of the socket, both elements (AB) fit together and each flange penetrates into its corresponding groove, reaching the locked position that prevents the recoil between said elements.

    For subsequent disassembly, the system also incorporates a tool that allows disassembly of the joint manually, easily and without damaging the elements to be joined, in the form of a lever and characterized by an end or handle designed to press manually, followed by a fold acting as a cam, sliding on each tab, and protrusions on the opposite end, which serve as a support point.
    This tool minimizes the effort to be applied and limits the path of the eyelashes to avoid excessive deformation that could damage them. In this way, the profiles do not suffer any deterioration and can be reused. It is also important to highlight the self-blocking character of the tool, that is, once activated and in its final position, it remains stable, eliminating the need to maintain pressure during the process of releasing the other tabs. 5

    The disassembly procedure is carried out in the following stages:

    A. The tool is introduced into the cavity caused by flexing each flange during the assembly process. The fold of the tool must rest on the flange and the protruding ends 10 under the edges of the profile.

    B. The tool is pressed as a lever so that the fold slides over the flange, acting as a cam and pushing it in until it leaves the slot releasing the mechanism, at which point the tool reaches the end of its travel and stays in that stable position.

    C. Proceed in the same way on the remaining tab using another tool identical to the previous one.
     twenty
    D. Once two tools are in their unlocked position, the joint can be disassembled by manually separating the profiles without them having suffered any deterioration and therefore being ready to be reused.

    Preferred Embodiment Example
     twenty
    By way of preferred embodiment of the "Retention System for Joints", in the light of Figures 1-17, it can be seen how the joint between two square tubular profiles 1-2 of carbon steel is approached, making use of the present invention.

    Thus, for example, using Laser technology, it is possible to make the cuts on both 25 profiles, making two grooves 5 on the upper profile 1, while on the lower profile 2, it would be necessary to make the corresponding socket 3, and the four cuts that give rise to two eyelashes, the latter, made on the upper surface of said lower profile 2, and adjacent to the socket.
     30
    From the profiles described, in order to carry out the connection between them, it would be sufficient to manually and perpendicularly insert the upper profile 1 inside the lower profile 2 by its socket 3, forcing the two tabs 4 to flex to as both profiles approach and until both fit at the end of their path, at which point the tabs 4 are introduced in their corresponding grooves 5, coming into contact with 35 lower and upper edges of the grooves 6-7, and preventing the recoil between both profiles 1-2.

    With respect to tool 8, it can be made from a simple folded sheet arranged to leverage as shown in Figures 12-17, so that when pressing on the 40 tabs 4, they make them leave their grooves and the blockage is released, minimizing the effort to be applied and limiting the path of the tabs 4, in order to avoid excessive deformation that eventually deteriorates them.

    In accordance with the disassembly procedure, it is carried out by inserting the tool 8 by 45 its opposite ends to the handle, into the access cavities inside the profile 2 that the tabs 4 have left free when flexing, so that the fold of the tool 9 rest on the tab 4, so that immediately after pressing the tool 8 as a lever, we make the tab 4 get out of its slot 5 deactivating the corresponding blocking 6-7 and coinciding this moment with the end of the travel of the tool 8 , which finds a stable position as shown in figures 15-17.

    Thus, in figure 16, the tool 8 has already been introduced, although the tab 4 still remains in the closed position inside the slot 5. On the contrary, in figure 17, the tool 8 is
    It is in its final position without the need to continue exerting pressure on it, forcing the flange 4 to remain in the open position, without resting on the groove 5 and therefore without preventing manual separation between individual profiles 1-2. That is, the mode of operation of two disassembly tools 8 is self-locking so that when they reach their final position, they remain stable, making the disassembly more comfortable without the need to be pressing 5 the two tools 8 at the same time in order to carry out the separation between profiles.

    Once the joint has been disassembled, two tools 8 are removed and the tabs 4 return to their closed position, leaving 1-2 profiles, available to re-perform the joint as many times as desired. 10

    By way of preferred embodiment, alternative configurations based on the same invention can be seen in Figures 18-23.

    It is not considered necessary to make this description more extensive so that any person skilled in the art understands the scope of the invention and the advantages derived therefrom. The materials used in the manufacture of each profile, its dimensions, the use of tubular profiles of square, rectangular, circular section or even open profiles or any combination between them, including any other type of element to be joined, the relative position between said elements , the different possible configurations of tabs-grooves, the degree of penetration of one over the other, the types of joint, and cutting technology, will be susceptible of variation as long as this does not imply an alteration in the essentiality of the invention.

    The terms in which the report has been described must be understood in a broad and not limiting sense.
