    Description


    [0001] The present patent relates to multi-purpose lockers in general, more specifically to improvements introduced in multi-purpose lockers which, in accordance with the characteristics thereof, possesses as a basic principle the introduction of a proper and specific set of devices and improvements in proprietary structures to optimize the structure of a multi-purpose locker, in order to provide a safe, comfortable and pleasant utilization of the latter to store the most varied types of products in general, being based on a robust, safe and lasting set of devices. With a specific design and shape, easily accessible for a better adaptation, safety for the users, practical handling, functionality and accessible cost and due to its characteristics and dimensions, is easily adaptable to the locker structure and to several different types of products, users and places, regardless of the characteristics thereof.

    [0002] Document DE-U-9419729 describes a metallic locker obtained from separate elements from the sides, the back, the roof and floor plates and shelves, being the elements mentioned as linkable with rail hooks incorporated in each of said elements. The locker specifically demonstrates that when disassembled it occupies little space and is easily transported.

    [0003] The patent in question is characterized in that it aggregates components and processes in a differentiated concept to meet the various requirements the nature of its use demands, that is, a better utilization of multi-purpose lockers. Such concept provides the locker great efficiency, functionality, versatility, strength, durability and safety due to its excellent technical qualities, thereby providing advantages and improvements to the product as a whole, the general characteristics of which differ from the other shapes and models known in the current state of the art.

    [0004] The present patent consists in the utilization of modern, versatile, efficient and functional improvements introduced in multi-purpose lockers, formed by an assembly of properly incorporated mechanical and functional solutions comprising a complete and differentiated multi-purpose locker, with an exclusive design, optimum finish details and proprietary characteristics, and incorporating a set of devices and improvements in proper and specific structures of high durability and strength, made of metallic material or similar material, properly arranged (fitted and attached) to the basis structure thereof such as a differentiated design for the doors as a safety any finish element, a ventilation on the doors to help air circulation inside the locker, a storage compartment as a secondary element to store objects, a multi-point type lock as a locker closing element and a door shield as a safekeeping and identifying element, so as to form a complete and fully safe set of improvements, whose shapes and internal and external arrangements provide a perfect integration to the structure of the multi-purpose locker, with the purpose of generating a general improvement on the way users handle the latter.

    [0005] The present improvements introduced are based on the utilization of proprietary structures comprising components and processes in a differentiated concept, making it possible to solve some of the main inconvenients of the other shapes and models of multi-purpose lockers known in the current state of the art and employed to store clothes or objects in general in schools, gyms, factories, offices, clubs, etc., which are located in an operating range in which the handling difficulties and accidents are frequent and whose shapes and/or products are obsolete and based on simple adaptations, as the ones locally handcrafted, which causes fragility and difficult maintenance, low strength and durability, or else they have a large structure, which means high costs, are difficult and slow to install and need high skilled labor.

    [0006] The objects, advantages and other important characteristics of the patent in question can be more easily understood when read jointly with the appended drawings, wherein:
