LOCK NUT OR SCREW WITH COMBINATION FOR WHEELS

VEHICLES

FIELD OF THE INVENTION The present invention is related to the automotive industry or the spare parts manufacturing industry of this industry. More specifically, it is related to the vehicle accessories manufacturing industry, and more specifically to the manufacture of bolts, nuts, or security studs. BACKGROUND OF THE INVENTION

In the automotive field, wheels are commonly secured to a hub or axle of the vehicle by a plurality of wheel nuts or lug nuts. Such wheel nuts must be tightened to a specified torque to ensure that the wheel is securely retained in the hub. A nut that is too tight runs the risk of damaging the nut or stud that extends from the hub, while a nut that is not tight enough can risk loosening. It is well known that loosened wheel nuts are undesirable due to the possibility of the wheel becoming unstable or loose and possibly losing the wheel.

Previous attempts to indicate whether a wheel nut is tight has been to provide a body that can be located around the nut that has an indicator thereon to indicate to the user when the nut has rotated out of the desired position.

Such prior devices have been difficult and time consuming to install, remove, and operate. In particular, such prior designs have an opening to fit around the wheel nut that has a fixed diameter. Due to this fixed diameter, it has previously been necessary to thoroughly clean the nut prior to device installation to prevent accumulated dirt and debris from sticking to the device or preventing installation. Such fixed diameter devices have also been difficult to install in cold climates where the Device may shrink due to the coefficient of thermal expansion of the material used to form the device. Other difficulties with prior designs are that the covers have included a fixed cross-sectional opening through the device. Such a fixed opening has made installation difficult due to the need to precisely align the cap with the wheel nut. Such accurate alignment is difficult in dirty environments, especially when the wheel nut is not properly cleaned. Furthermore, prior devices have used a different colored portion that is only visible because the wheel nut has been turned from a position where it is covered by an adjacent cover. In dirty environments, such color differences are difficult to see when the entire wheel assembly is covered in a layer of dirt, road salt, and other debris.

Currently, around the world there are different types of lock nuts and bolts (known as security studs) that are used to prevent as much as possible the theft of tires.

Within the current security nuts and bolts, there are different types. All consist of a nut or bolt with a head of a specific shape so that common tools cannot adapt to this shape and thus cannot be removed.

Some just instead of having the typical hex nut shape to be clamped and turned, have some different pattern, which the hex shape doesn't work with and supposedly only the wrench with the specific pattern works.

Others, in one embodiment, are cylindrical on the outside and carry this specific pattern on the inside or at the tip, and there is also a mode in which a type of rotating ring is added so that they can be held and turned with greater difficulty.

Finally, there is a design that leaves the specific pattern at the bottom on the perimeter and has a crazy hexagonal head that prevents tools from approaching the pattern where the nut or bolt is fastened.

The function is to prevent the theft of kidneys and tires by placing a nut or screw impossible to remove without having the tool that carries the combination of bolts specific.

US Patent 9,200,666, Chain, describes a vehicle wheel fixing assembly that includes a main body and a hollow sleeve of cylindrical shape. The main body has a wheel contacting end, a sleeve retaining section, and a key receiving end that includes surface contours defining a first key pattern. The cylindrical-shaped hollow sleeve has a first end and a second end, the first end being open with the main body extending therein. The sleeve retaining section retains the sleeve to the main body for free rotation about a central axis of the main body. The sleeve retaining section is further configured to prevent movement of the sleeve in an axial direction of the main body. The second end is closed covering the key receiving end and includes a key receiving opening that provides access to the first key pattern.

US Patent 9,777,761 to Chain discloses a vehicle wheel fixing assembly. The main body has a wheel latch end, a key portion, a first support section, and a key receiving end. The key portion has a plurality of surface contours defining a first key pattern configured to engage a tool for twisting movement of the main body. The first sleeve has an open end and a closed end. The open end is installed in the first main body support section such that the closed end of the first sleeve covers the key receiving end with the key portion exposed relative to the first sleeve. The first sleeve is retained by the first support section to rotate about the central axis of the main body and is non-movably retained relative to an axial direction of the main body.

US Patent 9,969,210 to Fisher describes a locking device for a vehicle wheel. In some embodiments, the locking device includes a plate having an outer surface and an inner surface and at least one opening that extends through the plate, at least one enclosure that extends from the inner surface of the plate, at least one retaining flange extending from the inside surface of the plate, the retaining tab having a lateral locating portion and a radial locating portion having a slot and at least one lock cylinder extending through of at least one opening, a locking tab connected to at least one lock cylinder and movable from an unlocked position to a locked position.

In patent document WO2015180556, a coded locking rotary wheel is disclosed. The castor wheel is of round disc shape, comprising a central through hole provided in the center of the castor wheel, a notch arranged on an outer edge of the castor wheel, and a castor wheel condition detecting device provided on the edge. outside of the rotating wheel but not in the notch and used to detect whether the notch points to a certain position or not. Also provided is a coded lock comprising the coded locking rotating wheel, comprising, in cooperation with the rotating wheel, a rotating wheel status response device and rotating wheel status display devices, the status response device Wheel is connected with the rotating wheel display devices. The security status of the coded lock is fed back by detecting if the code is completely broken and if a signal is transmitted at the same time.

In patent document WO2013049913, by BOYCE BRUCE R et al, an apparatus is described for locking and marking a wheel nut, the wheel nut being able to rotate about a central axis to a secured position. The apparatus comprises a substantially cylindrical body having a toothed central bore sized to closely surround and engage a periphery of the wheel nut. The cylindrical body has a groove therein to allow the cylindrical body to be radially expandable. The apparatus further comprises a first extension that extends perpendicularly from the body having an indicator thereon and a second extension that extends perpendicularly from the body to an opposite side thereof. The second extension has a distal end adapted to overlap and mate with a first extension of a adjacent wheel nut cap to cover the adjacent wheel nut cap indicator when the wheel nut is in a secured position.

All these devices of the state of the art have some exposed point that, if it can be firmly held, the nut or bolt can be extracted in just seconds,

The methods used to remove the current security studs are:

> Get the original security die.

> Universal dice.

> Striated impact socket.

> Reverse threaded socket.

> Specialized equipment for extraction of studs.

OBJECTIVES OF THE INVENTION

One of the objectives of the present invention is to make equipment that cannot be withdrawn, stolen, violated, or violated with any of the aforementioned or known methods today, thereby guaranteeing the greatest security to the user that their Tires or braces will not be stolen.

Another objective is to make it possible for the nut or bolt to only be extracted or tightened to fix the wheels, if you have the right tool that has the specific combination of bolts. Still another objective is to achieve a design that is easy to manufacture, simultaneously reducing manufacturing time and also reducing production costs by simplifying the elements that make up the device for fixing the wheel to the mass of the car and also reducing the number of these,

And all those objectives and advantages that will become apparent upon reading this description, accompanied by the figures that form an integral part of it and that are attached for illustrative but non-limiting purposes.

DESCRIPTION OF THE INVENTION

The invention object of the present description, in its simplest preferred embodiment, consists of a nut or screw with a disc with holes and a socket with bolts designed to be housed in these holes and to be able to tighten and loosen said screw or nut. The security of this device lies in the pattern of distribution and depth of these holes, which are consistent with the pattern of distribution and lengths of the bolts of the die.

With the distribution pattern and depth of the holes on one side and the lengths of the bolts, unique matches can be established between bolt or nut and die so that any other die bolt pattern and length does not match the pattern of distribution and depths of holes, and the turning of the nut or bolt cannot be carried out and the wheel or tire cannot be separated from the vehicle.

Depending on the configuration of the hole in the rim where the bolt or nut will be housed, it will be the configuration of these. The configuration can be conical, spherical or flat.

It is also possible to have a conformation of the holes or holes that are different from the circular holes, and this also must be reflected in the cross sections of the bolts of the die, this being another security element.

A second preferred embodiment of the present invention consists of a cap or bushing, inside which a nut or bolt is housed, which is the one that will be fixed to the rim of the rim or tire and to the mass or hub of the vehicle. Like the first preferred embodiment, the nut or bolt has holes in the disc with a distribution pattern and different depths. The cap also has a hole distribution pattern coincident with the nut or bolt distribution pattern.

The socket that can tighten or loosen this device has a distribution pattern, and dimensions of length and width and cross section of the bolts, consistent with the distribution pattern, dimensions and conformation of the cap and nut or screw holes.

In a third preferred embodiment, which is the most complex of the present invention, the first component is the flat head lock nut / bolt. This is tightened with the bolt socket, which does the function of (like the original nuts or bolts of the car) to stop the rim of the car.

On this base nut, the second component that we will call "cap or cap" is placed, which comprises a nut covered by said cap or cap. The cap is closed from the bottom so that the nut is inside, impossible to get out and with an adjustment that allows it to rotate. The mentioned nut can only be tightened or loosened by means of a bolt-on socket specifically designed for that nut. To reach this nut, the bolts must pass through the cap, through the holes previously aligned on this cap and coinciding with the internal nut. The cap turns in a crazy way, without affecting the part below, that is, it can turn in any direction without moving the nut. Thanks to this cap, it is impossible to loosen the cap just by holding the surface.

In this mode, the installation process consists first of fixing the wheel by means of the base nut. Then fix the cap by means of the cap nut, and for this you must slide the bolts through the holes in the cap and by turning the cap, make the holes in the cap coincide with the holes in the cap nut to secure this cap nut to the stud bolt. Although the cap nut is attached to the stud bolt, the cap itself rotates freely. To remove the cap and leave the base nut accessible for removal, the wrench with the bolts must be inserted

Figure 1 illustrates the base nut 1 in conventional perspective, seen from the front bottom. This mode, which is the mode in which the body 4 that will be in contact with the wall of the rim bore, is conical. In this conical body there are recesses 3 so that the bolts of the die can penetrate further inward. From this perspective, the holes 6 are perceived in this way. The internal cord 5 of this nut is what will allow the nut to be screwed on. This internal cord 6 is run from end to end, to allow in some of the embodiments of the present invention, that the screw of the dough or hub protrudes to screw in the fixing nut of the cap or cap. Disc 2 of this element of the three modes of our lock nut is the one with the holes with a distribution pattern and configuration and dimensions. Although in this drawing the distribution pattern, dimensions and conformation is homogeneous, we have already said that these elements can be determined to form unique combinations that define the characteristics of the bolts of the die that allows tightening and loosening this nut.

Figure 2 illustrates the same base nut in conventional perspective, but perceived from the top front. In this perspective, the holes 6 can be better perceived and less body 4 that will be in contact with the hole in the rim. This element drawn in this figure 2 and in figure 1, is the element that will appear in the three preferred embodiments of the present invention. In the first modality, it is the only element, with different patterns of perforation distribution and different dimensions and conformations of these.

In the second embodiment, this element is located within the cap or bushing that will be illustrated later.

In the third preferred embodiment, this element will be covered above with the cap or bushing with a cap nut inside.

Figure 3 shows the appearance of the base nut, in its spherical form, from a front view. In this embodiment, the body 4 of the nut or bolt that will be in contact with the bore of the rim has a hemispherical configuration truncated below. In everything else the nut is the same.

Figure 4 represents the appearance of the base nut on its underside, of the flat base nut mode. As can be seen in this modality of nut or screw 1, the body 4 of the other modalities does not exist. It is clear that these drawings, although we say that it is a nut or bolt, depending on whether the mass or hub where the wheel to be fixed goes, has a bolt or a rope, illustrate a nut.

When it is a screw, this element has a straight rope stud, and depending on the preferred embodiment, the stud protrudes outwards or not.

Figure 5 shows the appearance of the cap nut 7, seen from the lower front part. This cap nut 7 appears only in the preferred embodiment three already indicated. In mode 2, this cap nut is replaced by the base nut in any of its forms, conical, spherical and flat. This cap nut is going to be located inside the cap or cap and fulfills the function of joining it to the nut or screw, in the first preferred embodiment neither the cap or cap, nor this cap nut, are necessary. Even if In the illustrated embodiment, in addition to the disc of the cap nut 8, there is a central disc 9 with greater thickness, this may be non-existent, and this nut would fulfill its function. However, to give it greater stability in the conformation, the latter is added to increase the length of the rope 10 to give more firmness to the winding.

Figure 6 is the appearance of the cap nut of Figure 5, but drawn in conventional perspective, seen from the top. In addition to the central disk 9 and the upper disk 8, the holes 11 can also be seen, which will house the bolts of the socket to tighten or remove the cap nut and the cap or cap. These holes are designed to have a distribution pattern, dimensions and conformation such that the bolts of the socket only coincide with a single socket and in a single position. For example, if you have a longer bolt and it coincides with the deepest hole, the other bolts will not be housed in the other holes and the tightening or removal of the cap cannot be carried out.

The same happens if the bolts of the die do not have the same distribution pattern as the holes or holes. Even the bolts can suffer deformation or even destruction if only a few bolts coincide.

Figure 7 is a conventional perspective drawing of the cap 12 of two of the preferred embodiments of the present invention, in the form of the cylindrical cap, seen from the bottom, in its open mode, that is, with a central hole 16 wherein the end of the screw or nut can be housed when their length exceeds the cap nut in the third preferred embodiment of the present invention or exceeds the base nut in the second preferred embodiment. In the disk 14 of the cap, the holes of the cap 15 are located, which will not have the depth variables to establish safety, because all the holes or holes must go through it to affect the holes or holes of the nut or screw. base or cap nut. All other characteristics of determining a security combination if they have them. That is, the distribution pattern, the diameter or perimeter and the cross section. Figure 8 illustrates a conventional perspective view of the hood illustrated in Figure 7, but viewed from the top. The same elements illustrated in figure 7, except for the inner disk 14, of which the upper outer face is perceived, are illustrated in the present figure.

Figure 9 shows a conventional perspective view of the cap 12 illustrated in Figure 7, but in its conical embodiment, viewed from the bottom. All other items are the same.

Figure 10 illustrates the same embodiment of Figure 9, in conventional perspective, but seen from the outer upper part. All other items are the same.

Figures 11 and 12 illustrate Figures 7 and 8 but in their closed mode, where the central perforation 16 is absent, all other elements are referenced in said Figures 7 and 8. This preferred mode has the disadvantage of not being able to absorb some excess length of the wheel or tire fixing bolt or nut. All other items are the same.

Figures 13 and 14 illustrate Figures 9 and 10 respectively, in their closed mode. All other items are the same.

Figure 15 illustrates the tightening socket of the base nut, in conventional perspective seen from the bottom. This die 17 has a main body 18, which on its lower face has bolts 20, the characteristics of which determine its specificity of application in a certain screw or nut for fixing the wheel to the mass or hub of the automobile. Although certain characteristics of the bolts are shown in this figure, they may present, as already mentioned throughout this description, differences in their distribution pattern, length and diameter or perimeter and conformation of the cross section. This conformation throughout the present description and the attached figures, have been cylindrical, but they can also be regular or irregular polygonal. Also the conformation of the head 19 can vary, giving an additional security element. The hole 21 is for when the socket is used in the first preferred embodiment and the nut or bolt has a end that sticks out of the base bolt or nut.

Figure 16 illustrates in conventional perspective the same die of figure 15, but seen from the top. The referenced elements are the same as in figure 15.

This die may be applied in preferred modalities 1 and 2, that is, when the device consists exclusively of a base nut or screw or when said device or nut is housed in a cap or bushing, and possibly the lengths of the bolts for the second. preferred mode will be longer.

Figure 17 illustrates in conventional perspective the cap nut tightening socket, seen from the bottom. Due to its configuration, this die is specific for the third preferred mode. This is noticeable because the tightening or rotation to remove the cap is carried out by means of a rod that is inserted into any of the holes 23, which does not allow a very high torque to be applied. Already in this figure a specific distribution pattern is beginning to appear.

Figure 18 illustrates the die of Figure 17 also in conventional perspective, but seen from the top. The different elements are the same referenced in figure 17.

Figure 19 illustrates the invention of the present disclosure, in its preferred embodiment number three, in explosive. This is the most complex embodiment and includes the base nut 1, the cap nut 7 and the cap or cap 12. These elements have already been described in detail in the previous figures. They may have different conformations already described.

In summary, the present invention has three preferred embodiments. The first and simplest is the one consisting of a base nut, the security of which lies in the characteristics of the holes or holes, which prevent a wrench that does not take these characteristics into account, not being able to remove said base nut. These characteristics are the distribution pattern of the holes or holes, their dimensions (diameter or perimeter of these and their length), and the cross section, any polygonal or circular section.

The second preferred embodiment is made up of the said base nut or screw, but housed in a cap or cap, a situation that increases security, because the drive key or socket must meet the appropriate characteristics to pass through the cap or cap and then fit into the holes in the base nut or screw.

And the third preferred mode has just been described.

Figure 20 is the part of the assembly that differentiates the modality of the device object of the present description in which the car instead of having a screw has a rope. In this other preferred embodiment, which responds to the fact that the mass or hub has a rope and no screw for fixing the wheels or tires. And it consists of a base nut 1 as illustrated, but with a stud 26 running through it. It is clear that the base nut 1 can have different configurations in addition to the conical illustrated, that is, it can be flat, or hemispherical, or any other configuration that has the holes in the rim to be fixed.

An analysis of the different preferred modalities of the present invention allows us to conclude that the part that presents the most problems for its manufacture is the cap. It requires removal of material to form the cavity, which is complicated.

On the other hand, this form of cap is only required to prevent the base nut from being fixed on a tool, and turning it to remove it from the mass and remove the wheel, without the need to have the combination of the perforation pattern reflected in a tool. of with bolts, violating the security of the fixation. This requirement only occurs when the base nut protrudes from the hole in the rim where this part is housed.

Another safety aspect is that with the cap it is modified, it is the length of the bolts of the wrench that will be used to fix and remove the base nut. In addition, as the base nut covers the cap, despite having the same pattern of distribution of the holes or holes when inserting a single bolt, for example, this will not allow the removal of the base nut or cap. It would be necessary to introduce at least two loose bolts, so that with any wrench or pliers the base nut can be turned and unscrewed. As there is a very specific distribution pattern to these holes, a loose bolt can be easily matched, however if a person does not have the corresponding key, the possibility of placing a second loose bolt is drastically reduced.

To achieve the advantage indicated in the upper paragraph, but reducing the complication of the manufacture of a cap, in the embodiment illustrated in Figures 21 to 25, the cap is replaced by a disk 27, shown in Figure 21, said disk is rotatably fixed to the base nut, by means of a bearing 28 which, by means of stud bolts, is in turn fixed to the base nut 1.

Figure 22 shows the conformation of the rolling means-fixing means, of the disk that replaces the cap. In one of its embodiments, the bearing means-fixing means, consisting of a hollow cylinder, has two external diameters, a lower one 29 smaller and another 30 at the larger upper end. In another of the modalities, the means of bearing-means of fixation is solid, that is to say it does not have any cavity, and it is used when it is the stud that comprises our invention.

As can be seen in figure 21, the bearing means-fixing means, penetrates through the upper part and is housed, in its largest external diameter inside the disk and in its smaller diameter part, inside the base nut. .

The smaller outer diameter segment of the clamping means-bearing means is fixed to the inside of the flare 31 of the base nut 23 by means of an adhesive and studs that laterally pass through the base nut and reaches the bearing means-clamping means. . In figure 23, which illustrates the base nut, three elements can be seen, the flare 31, the formed step 33 and the thread 32.

Figure 24 illustrates the disk 34 that partially replaces the cap. And the replacement is partial because this disc does not surround the base nut. This figure illustrates the step formed by the two internal diameters that said disk has, said diameters corresponding to the two diameters of the rolling means-means for fixing the disk to the base nut.

Finally, there is a last element in this preferred embodiment of the invention that it is not always going to be added. This element is a ring 36 illustrated in Figure 25.

This item is to be used when the base nut is exposed above the rim level. If the nut protrudes and can be secured by a turning tool, all the security of the present invention is lost. Then, in this situation, this other element is required to prevent fraudulent access to the base nut. For the installation of this element and its fixing, the external diameter of the disc 27 and the major external diameter of the base nut are different. The outer diameter of the replacement cap disk being larger, said ring 36 will be kept in place without preventing its rotation, by said disk 27. The ring will then rotate freely, always in sliding contact with the base nut, preventing any tool other than the die, designed with the bolts in the proper distribution, it allows to fix said base nut and turn it.

Observing the modality with greater security of the modality without cap, we will see that it is very similar to the modality with cap, with the difference that the cap is replaced by two independent pieces, the disc 34 and the ring 36.
