    DESCRIPTION
    Nail Clamping Device OBJECT OF THE INVENTION
    The present invention belongs to the DIY and carpentry sector, and more specifically to tools or tools for fastening screws or nails in nailing or hammering processes.
    The object of the present invention is a nail fastening device that in addition to allowing a comfortable and simple nailing process, allows access to narrow and inaccessible places where a user's fingers cannot, avoiding any possible damage caused by hitting on the fingers, and also guaranteeing a safer and more accurate hit, providing great precision and control when introducing the nail in optimal position, that is, perpendicular to the surface.
    BACKGROUND OF THE INVENTION
    At present, there are many professionals and individuals who face the task of nailing or inserting nails on surfaces of all kinds, either on vertical walls to hang pictures or similar, as on many horizontal surfaces or during assembly of domestic furniture, whose parts are acquired directly without mounting.
    It should be noted at this point that when the word "nails" is mentioned here, it is referring to any metal part suitable for interlocking on a surface, such as points, nails, screws, bolts, scarps, staples, tacks, etc.
    Thus, it has been detected that this usual process of nailing or inserting nails on a surface continues to present several drawbacks, among which at least the following stand out:
    - Requires the intervention of the user's fingers to hold the nail in a
    5
    10
    fifteen

    25
    30
    Optimal interlocking position (position perpendicular to the plane of the surface where the nail is to be inserted), which often causes the pounding or “crushing” of the fingers when erring in the attempt to strike on the nail head, usually by means of a hammer, rubber mace or similar.
    - The previous point also has the associated problem of the low security offered to the user in this way of proceeding, where situations are often created where the nail tilts or moves to the side, without any guarantee that the hit will have success, or be twisted or diagonally key.
    - In addition, it often happens that, due to their size, the user's fingers cannot access narrow, small or curved places, where space availability is very limited.
    - Another problem lies in the fact of frequent falls or loss of nails, where it is sometimes difficult to maintain an adequate orientation of the nail and finally the latter falls to the ground, with the consequent discomfort for the user, both in waste of time, as in material, not to mention the risks derived from having a nail on the floor (scratching of the floor of the home, accidents for small children or pets when taking the nails to the mouth, tire punctures, etc.).
    DESCRIPTION OF THE INVENTION
    By means of the present invention, the aforementioned drawbacks are solved by providing a nail clamping device that in addition to allowing a comfortable and simple nailing process without the need to use the user's fingers, prevents loss or falls of the nail in question, also allowing access to narrow and inaccessible places where the fingers of a user cannot reach, and consequently avoiding any possibility of damage or “crushing” caused by hitting one's fingers, thus guaranteeing a safer and more accurate hitting with respect to traditional techniques, and in a position perfectly perpendicular to the nailing surface.
    In addition, the device of the invention also stands out for allowing its use for nails.

    of different section and diameter, being useful for both circular section and rectangular or quadrangular section nails, thus increasing considerably its applicability.
    More specifically, the nail holding device object of the invention comprises: a rod having an end provided with a "V" configuration profile between whose internal walls a channel for the accommodation of a nail is defined; and an auxiliary body, coupled to the end of the rod in position delayed with respect to the "V" profile, that is, closer to the central part of the rod, where said auxiliary body in turn has at least one cavity within which it is located at least one magnetic body (or magnet) to allow a magnetic attraction to itself of the nail housed in the profile channel. Therefore, the invention resides in this "binomial" of elements formed by a rod with "V" profile, plus an auxiliary body provided with at least one cavity and at least one magnetic body.
    Preferably, the "V" profile comprises a central recess and two lateral branches that start from said central recess and diverge outward to a pair of points coinciding with the end of the rod. Thus, the clamping device described herein has a double bend, both in its central vertex or inlet and in the distal ends of its two lateral branches that make up the "V" of the profile. This allows to increase the range of different nail diameters with which the device of the invention can work.
    On the other hand, it is envisioned that the auxiliary body can be longitudinally movable along the end of the rod. This characteristic will allow the nail to always be in direct contact with the magnetic body, thus favoring an optimal vertical orientation of the nail, the latter being adhered and securely attracted by the magnetic field generated by the magnet at all times. Thus, if the diameter of the nail is very small (for example, just 0.9 - 1.5 mm.), It will be required that said nail be located in the deepest part of the profile channel, with the auxiliary body displaced towards behind; while if the nail has a very large diameter (for example, 4.3-4.9 mm.), said auxiliary body will be required to move

    30
    longitudinally forward, so that the lateral surface of the nail contacts the magnetic body with a sufficient magnetic force to maintain the nail in a vertical and fixed position and orientation.
    Regarding the number of cavities and magnets, their geometric shape, or their specific arrangement in the auxiliary body, it should be noted that these may have multiple configurations and final solutions in order to adapt to the geometric shape of the nails that you wish to use in every moment, without in any way varying the spirit or essence of the invention. Therefore, it could have a single annular magnet, or a pair of magnets in an angular or opposite distribution of them, with an arcuate shape of these, etc., and where at least two points of contact with the nail exist, the stability, positioning and clamping of the nail in question is greatly improved.
    Furthermore, according to a preferred embodiment of the invention, the above-mentioned tips of the "V" profile have a beveled inner surface. This special beveled tip, preferably at an angle of 45 ° with respect to the imaginary axial axis of the profile, it will allow the device of the invention to be able to hold nails of rectangular or quadrangular section, so that said beveled surfaces of the two lateral branches of the "V" profile can obtain a perfect coupling and grip to the perpendicular walls of a nail of rectangular or quadrangular section.
    In relation to the materials of the rod and the auxiliary body, it is envisioned that these may be diverse: plastic, metal, rubber, elastomer, or a combination of them, constituting a multicomponent solution. It should also be noted here that the device of the invention constitutes a work tool of light weight and small dimensions, with the capacity to be stored in any suitcase, drawer or small space available, also assuming a product of simple manufacture and economical

    PREFERRED EMBODIMENT OF THE INVENTION
    Several examples of preferred realization are described below, mentioning the figures cited above, without limiting or reducing the scope of protection of the present invention.
    Figures 1 and 2 show the device (1) for fastening nails of the invention, which comprises:
    - a rod (10) having an end (E) provided with a "V" configuration profile (20) whose internal walls define a channel (21) for housing a nail (C), as is represented in figure 3, and
    - an auxiliary body (30) of flexible material, although it could well be of rigid material, shown in figures 3 and 4, longitudinally movable along the end (E) of the rod (10), and coupled to said end ( E) of the rod (10) in position delayed with respect to the profile (20) in "V", where said auxiliary body (30) has in turn a cavity (31) within which a magnetic body ( 32), such as a neodymium magnet, which in turn generates a magnetic attraction of the nail (C) to itself, the latter remaining in a fixed, secure and stable vertical orientation.
    Thus, different embodiments for the rods (10) are shown in Figures 1 and 2, a first section of cylindrical section and a second subsequent section of hexagonal section being shown in Figure 1; while the rod (10) of Figure 2 has a hexagonal section along its entire length.
    According to a first preferred embodiment, shown in Figures 5A to 5D, the "V" profile (20) comprises a central recess (22) and two lateral branches (23) that start from said central recess (22) and diverge out to a couple of points (24) coinciding with the end (E) of the rod (10). In all the examples shown here it can be seen that the channel (21) defined by the profile (20) in "V" It is oriented in the
    5
    10
    fifteen
    twenty
    25
    30
    longitudinal direction of the rod (10), that is, where the central recess (22) or lower vertex of the "V" co-indexes with the most delayed point of the profile (20) with respect to its lateral branches (23).
    In said figures 5A to 5D it can be seen that the angle of separation between the lateral branches (23) is a growing angle, constituting elongated branches that open outwardly as ones in a vertical direction. More specifically, in said figures 5A to 5D it can be seen that the tips (24) of the profile (20) have beveled inner surfaces (25), which are expected to form an angle (a) between 40 ° and 50 °, with the imaginary axial axis of the profile (20), being more preferably an angle (a) of 45 ° to allow a perfect coupling and grip of rectangular or quadrangular section nails, as shown in Figure 5D.
    Referring again to Figures 5A to 5D, it can be seen that the magnetic body (32) or magnet is always in contact with the nail (C), due to the magnetic attraction between the metal material of the nail (C) and the field Magnetic generated by the magnet. In this way, the nail (C) in question will always have at least three points of contact for its fixation and firm vertical orientation, two points of contact with the lateral branches (23) of the profile (20), and at least one point of contact with the magnetic body (32).
    With respect to the auxiliary body (30), this is preferably an elongated body provided with a longitudinal through hole (33), shown in Figure 3, for optimum coupling around the end (E) thereof. Thus, although ideally, as it seems logical to think, said longitudinal through hole (33) must have a diameter equal to or greater than the diameter of the rod (10) to allow coupling between both elements, rod (10) and auxiliary body (30) , according to the example of realization of figures 3 and 4, the auxiliary body (30) is made of rubber or elastomer, the diameter of the auxiliary body (30) is slightly "inferior" to that of the rod (10), obtaining this so that the auxiliary body (30) opposes resistance to displacement and does not easily move over the end (E) of the rod (10), and where manual and voluntary adjustment by the user is required to move said auxiliary body (30 ).
    5
    10

    25
    30
    In addition, said auxiliary body (30) has a recessed area (34) where there is a narrowing of its side walls, see figure 3. This particularity will favor a perfect coupling of the user's fingers to facilitate the movement of longitudinal displacement of the body auxiliary on the end (E) of the rod (10), and where said displacement will vary depending on the diameter and type of nail (C) that you wish to use at any time. More preferably, it has been contemplated that said recessed area (34) has a plurality of circular grooves (35), shown in Figure 3, to facilitate its grip by the user's fingers.
    On the other hand, in Figures 1 and 2 it is shown that, according to this embodiment, the rod (10) has a curved section (11) located in the intermediate position of the rod (10) and which defines an obtuse angle (P ) comprised between 120 and 180 °, said obtuse angle (P) being preferably 160 °. This feature allows the device (1) of the invention to access places or areas of reduced space, where it would be impossible to access in a conventional manner through the user's fingers, as seen in Figure 3.
    Figure 4A shows the device of the invention with its proximal end of the rod (10) configured with a male coupling of standardized type E6.3 mm (one quarter inch), for coupling to a handle (M) by means of a tip-holder element (P) in order to securely fix said proximal end of the rod (10). At this point it should be noted that, although the E6.3 mm connection has been discussed here, the device for securing the invention is equally valid for other male or female connectors or couplings, the most common of which are the following: C8, C6.3, C4, A5.5.
    Notwithstanding the foregoing, as shown in Figure 4B, the fastening device of the invention could acquire other final solutions, such as directly coupled to a screwdriver (D), or any other gripping element that uses the basic characteristics of The present invention.
    According to another possible embodiment of the invention, not shown, it is provided that both the end (E) of the rod (10) and the auxiliary body (30) can have a thread, so that the forward movement or back of the body
    5
    10
    fifteen

    25
    30
    auxiliary (30) can be adjusted by rotating the latter around the rod (10) to its location in the desired position. To do this, of course, the external threading of the rod (10) must have thread characteristics in solidarity with those of the auxiliary body (30), such as the diameter, pitch, depth or thread angle.
    In relation to figures 6A to 6E, there are other possible embodiments for the profile (20) of the end (E) of the rod (10), showing different configurations of its intermediate channel (21) depending on each application : stepped, with ridges and undulating valleys in the form of continuous sea waves, concave, convex, etc. , however, they may have other forms and configurations different from those represented here and that respect the fundamentals and essential characteristics of the device (1) of the invention.
    In addition, it is envisioned that the profile (20) may incorporate different solutions in order to retain the auxiliary body (30), and prevent the latter from escaping from the rod (10) in its backward movement forward and vice versa . Thus, according to a preferred embodiment shown in Figure 7A, the lateral branches (23) of the profile (20) have external walls inclined (26) slightly outwards, leaving the horizontal plane of the rod (10), of such that the auxiliary body (30) is prevented from moving towards the front of the rod (10), thereby preventing its exit.
    In figure 7B another possible embodiment of the profile (20) is observed, where in this case the external walls of the lateral branches (23) do maintain the horizontality of the rod (10), but their tips (24) have projections (27) acting as stop elements to prevent the auxiliary body (30) from leaving the rod (10).
    Figure 7C shows another possible solution to achieve the objective sought to prevent the exit of the auxiliary body (30), but in this case, preventing the exit from both the front and the rear of the rod (10). More particularly, in said figure 7C it is observed that the profile (20) has a recess (28) in its outer wall, so that its diameter is smaller than the diameter of the rod, which generates a stepping in the rear part of the profile (20) and that works as a stop element that prevents displacement towards
    5
    10
    fifteen
    twenty
    25
    30
    behind the auxiliary body (30).
    On the other hand in Figure 7D another possible solution can be seen in order to partially allow the displacement of the auxiliary body (30) both forward and backward. In this case, it is observed that the rod (10) has in its rear part an intermediate recess (29), in which the auxiliary body (30) is partially coupled. Said intermediate recess (29) is specially configured to allow longitudinal displacement of the auxiliary body (30) only a distance (D), as shown in Figure 7D. In this way a double step is generated, both to the left and to the right of said intermediate recess (29), acting as stop elements. In the view of Fig. 7D, the auxiliary body (30) completely displaced backwards is observed, a situation suitable for nails (C1) of reduced diameter. Otherwise, if we had a nail (C2) of greater dimension, the auxiliary body (30) should be moved the distance (D) forward, in order to cause contact between the magnetic body (32) and said nail (C2 ).
    According to another preferred embodiment, not shown, the fastening device (1) has an auxiliary body (30) metal, or hard plastic, such that the placement of a nail (C) in the profile (20) in "V ", Causes an instantaneous movement forward of said auxiliary body (30), without any intervention by the user, and where the only force acting is the force of attraction between the magnetic body (32) and the nail (C) metal.
    Going to mention now the figures 8A to 8D, in them you can see different possibilities for the inner side of the lateral branches (23) of the profile (20), all with a view to achieving an improvement in the grip, grip and lashing of the nails Thus, in Figure 8A it can be seen that at least one of the internal faces of the profile incorporates a plurality of inlays (41) of high hardness and abrasion resistance material, such as diamond or boron carbide.
    In Figures 8B and 8C other possible embodiments can be observed to maximize the grip of the nails, and in which one of the internal faces of the profile (20) is appreciated,
    presenting in figure 8B transverse projections (42) or prominent ridges outwards, while in figure 8C there are transverse recesses (43) or valleys, and where both the projections (42) and the recesses (43) can be obtained by a manufacturing process by milling, or by forging, or by machining or laser engraving, 5 providing in this case an irregular striatum that acts as a "mordant" among others.
    Finally, Figure 8D shows another possible solution for the above-mentioned objective of optimizing the grip and clamping of the nails. In this figure 8D the existence of a plurality of transverse grooves (44), arranged in "zig-zag", that is, in a succession of ridges and valleys, practiced in at least one of the internal faces of the profile ( twenty).
    Therefore, by means of the nail holding device of the present invention, a working tool is provided which, in addition to allowing a simple and comfortable nailing process without loss or loss of the nail being used, allows its use for different types and nail sections, both circular and quadrangular. In addition, the device of the invention allows access to narrow and inaccessible places where the fingers of a user can not, ensuring a safe, stable hit in the clamping and control of the nail and accurate, and avoiding the user any possible risk of hitting the 20 fingers in his attempt to hold the nail.
