Description

Hand Screw

[0001] The present utility model patent has as its objective a screw model, for residential, commercial or industrial use, to which an original construction was given, with a view to improving its use, performance and efficiency in relation to existing similar models.

[0002] Screws have been known for hundreds of years and, all with similar characteristics and the same function, fixing body A to body B, or several other bodies into one, as needed, as a rule, the same technique; the desired surface is drilled, applied directly with a screwdriver and a multitude of others such as: "open-end", omega, philips,

[0003] hale etc. However, there are inconveniences, for example, if a housewife needs to remove the bathroom cabinet, to remove insects and / or dirt accumulated over time from the bottom, or even a utensil such as a salt shaker, kitchen cabinet, or remove the same cabinet to paint other rooms in the house, in these cases, she would hire a professional to carry out the aforementioned services and, in the end, would have to do the reverse process to replace the objects in their proper places.

[0004] The "panic" caused in every family in a house, by a clogged toilet, practically with the manual screw, does not exist, this is because instead of coming to the surface, the concern of the house's managers, where, how and when to find a professional available in the market for the event, or to buy extremely dangerous chemical products to handle, as well as the amount charged by opportunists for the emergency service, She herself, or her spouse do it, and better, using gloves and their hands, both to remove it and to replace it.

[0005] It is worth highlighting that the fashion, advertising and general commerce industries temporarily display millions of products and having temporary and stylish fixings is everything, because, in addition to not needing to hire specialized labor for fixing and unfixing these, this is done by their own employees, generally young girls and boys at a young age, it is good to have an accessory like a manual screw that can be divided into fixing and releasing objects without the use of any tools, and the body still

[0006] remain fixed, in addition to the suggestive finish, referring to the branch of activity or event, such as: the scissors are the movable nut of the screw that fixes a tailor's sign, a brush the removable head of the screws that fix the painter's paintings in an exhibition, or the "animal head" nut that fixes and serves as a commercial for a veterinary office, as well as a "mold" identifies the price list of a confectioner, the "butterfly nut" that fixes the sign, identifies the house or studio of a zootechnician, ecologist, naturalist, etc.

[0007] Visualizing these problems and with the aim of overcoming them, the Manual Screw was developed, the object of this utility model patent, whose advantage over others is that it allows objects fixed by them to be removed and replaced without the help of tools or professionals, in addition to decorating the environment with inherent identification of the professional and event.

[0008] The attached drawings show the arrangement in which the hand screw, which is the subject of this utility model patent, is located, in which: Fig. 1 shows it in montage and composition perspective. Figure 2 shows the structural and functional characteristics. Figs. 3, 4, 5 and 6 show its infinite applicability.

[0009] in accordance with what is illustrated in the aforementioned figures, the manual screw (1) figs. (1 and 2), consists of a screw with a fully threaded structural body (4 and 25), upper end called sub-head (4) also threaded, with a diameter twice that of the structural body (25) base of the limit and tightening sub-head (26) fly opens the way to increase the penetration power (24) and nut with internal threading (3) and (3A) with lower tab aimed at covering holes with a diameter above the standard in sanitary ware and others, to fix multiple objects on surfaces: vertical, horizontal, diagonal, ceiling, in all possible forms of fixation, with the creative and suggestive diversity of “head” nuts, depending on the event and user.

[0010] For example: a (nut) in the shape of a fish (27), suggests that there is an aquarium seller or fishmonger there, like the bird's head (10), suggests that there is a poultry farmer, farm, slaughterhouse, zootechnician or even a taxidermist, or the screw with a pencil-shaped head (8) fixing a sign, indicates that there is a haberdashery, bookstore, and also the screw with a paintbrush-shaped head (9) fixing a painting, indicates that it is an art gallery, painting studio and, dozens of other children's shapes, in addition to locking safely, will decorate children's furniture with the latches, from which it is concluded that the usefulness of the manual screw, adapts according to need.

[0011] The Manual Screw, object of this utility model patent, “brings with it” more forms of fixing in which the head (nut) (3) is embedded or glued previously on the part opposite to the intended view, to what will be fixed, such as: religious or non-religious images, statues, biscuit, etc. Where, the object becomes the nut itself, in which the same post-fixation on walls, pass on the optical illusion of being “levitating” fig. 5 (11, 12, and 13), as well as fig. 6 (14, 15, 16, 17 and 20), when fixing biscuit to walls.

[0012] The manual screw is slotted (2) applied like conventional models, that is; the desired location is drilled (5) and then the PVC bushing is inserted (6) according to the screw dimension, and with a wrench in the slot (2) screw it up to the base limit of the sub head (4) plus the thickness of the object (7) then drill the object so that it passes through the sub head (4) then, with the sub head exposed, screw on the desired head (nut) (3) using only

[0013] the hand turning it clockwise (3) fig. 1 and 2, until it touches the object, a picture for example (7) then, the final tightening, with the force that suits or, that the object supports, however, the aforementioned action will only be possible if the object to be fixed “allows” drilling, then comes the versatility of the manual screw, using the “rest / rest” method fig. 4, cut AA, in which, after marking, surface drilling and screwing, the object is “rested” on the

[0014] protection of the plastic support (28) at the lower and upper ends, of a valuable painting for example (fig.4 (7) avoiding damaging it, on the structure of the screw (1) outside the wall (5), and then screw the desired “head” nut (3) on the screw, which will fix the mentioned work with half of each nut applied fig.4 (7) cut AA. And, if you need to remove the object, turn it in the opposite direction, that is, in the counterclockwise direction.... manually.

[0015] Logically, a screw like this can be manufactured in all sizes, in different steels, general ferrous materials, metal, copper, bronze, aluminum, gold and, or even “mixed”, metal body, plastic head, acrylic, nylon, leather or wood, all with thousands of imaginable shapes!

[0016] The multiple industrial applications of the hand screw, which is the subject of this patent, include the metallurgical and polymer industries, the arts and decoration industry, the furniture industry, sculptors and artisans in general.
