SI24687A - A fast-clamping nut - Google Patents

Abstract

The present invention relates to a novel product, conceived as a quick-rotating nut having a hand-held sleeve (1), with a through cone hole (1.3) into which three or more jaws (2) are inserted which are interconnected due to intermediate springs (6) which maintain this overvoltage because they are always in a certain compressed state. The compactness of the system provides a plug (4) or an integrated plug (8), which is quantitatively linked to the number of jaws (2) and is screwed in each case by a screw (5) into specially rectangular apertures (1.1) cut out on the crank sleeve (1). The purpose of the plug (4) or the integrated plug (8) is to prevent the system from decompressing and at the same time be in the function of opening and closing - the locking of the fastening nuts.

Description

The essence of innovation and invention is that the inventor invents a new technical solution or enhances a known solution for centuries, just as we have presented in this patent application a technical solution of a fast-tightening nut by changing the structural concept of the assembly as a whole and adding a certain new useful - technical novelty and commercial value. Since their invention, the nuts as machine elements have not changed substantially in relation to the state of the art as initially set up, namely, a part which can be wound on another round rod material such that it is cut through a metric or aeolian thread that fits into the thread of the screw portion. Thus, these two components form one complete assembly, which is manifested in different technical versions and has found wide application and in all branches of technology represents the basic connecting - connecting part of two or more different components - elements in the higher assembly.

The fact that we have changed the basic design of standard nuts in such a way that it is no longer necessary to tighten the nuts as such - to rotate the entire length of the screw thread, but our fast-tightening nut, presented in this patent application, only pulls on the screw or. on a screw thread or flat round rod and block it - stop at that part of the screw or. the round bar on which we want to achieve the optimum barrier when we reach the obstacle. We do it all with one hand movement. In our case, it is up to the weighting disk, which gives our innovation a vital meaning.

The other essential technical indicator for the successful use of our high-speed nut is that by pulling on we have come to a component that we want to tighten with another component that forms a higher assembly and is used to better compress the compression force of these two or more components, tensile technique of rotating or winding the nut against the outer wall is an assembly that is or is being squeezed by our quick-tightening nut. We achieved this by cutting the same threads on our nut and the threads on the screw rod.

So in this final tightening or half turn or. In addition to the fastening nut, our high-speed nut takes on the function of a standard nut so that by connecting and fitting its internal thread and the screw thread, it ensures synchronous sliding against the place of tightening of the components and achieving the required or desired tightening forces of these two or more components - materials.

The next or third essential technical characteristic or property of our high-speed nuts is shown in the version, which does not have a threaded thread cut through, but its round and long cylindrical hole is coated with a sealing material, which is compressed around the tube in that part by pulling on a round tube. or where we want to stop our quick-release nut.

Based on the above, we have created with our innovation two versions of high-speed nuts for circular rod materials with a metric or eolian thread or any thread, and non-threaded materials for circular rod or square rods shapes or polygonal shapes, for example, four, six or more angles.

When tightening the nut to a bolt or attaching our high-speed nut to a circular or multi-inch rod material, a tightening force is essential, which is dimensioned and determined, on the one hand, by the necessary forces prescribed by the construction of the joining of two or more components, or stems from the need for preventing a particular component from slipping from a screw or screw rod.

In this sense and the requirement for quick recording and mounting of weights on the working pole, we conceptually designed the basic version of the fast-tightening nut, from which all other versions have developed, which have found wide applicability in all branches of industry and life. Exercise and fitness workouts with weights require a quick change of weight for weights that are mounted on a weight bar.

Until now, commercial manufacturers of fitness equipment and the known technical implementation of mounting a weight disc on a weight bar were such that we set a certain weight of the weight - the weight disc was mounted on the weight bar and fixed with a weight nut, which was usually a winged technical version, which means , the nut on the diametrical side had two handles or blades that were designed to allow the nut to tighten to the weight disk and to press it against the landmark on the weight bar. When marketing unpatented technical versions, we came to the realization that three groups of nuts in different design versions are being marketed. The first group consists of nuts that have a sleeve and a threaded thread. The second group is focused on spring tensioning devices - clasps that have a precisely profiled number of round spring threads with rod - straight-end levers for hand grip. When compressing these two levers, the spanner portion of the spring expands, so the circumference is larger than the circumference of the rod or rod and the spring is attached to the rod. When contact with the disc is reached, the spring levers are released to tighten the spring around the bar. The third group includes clamp bushings, which can be split bushings - clamps and generally bushings that have a threaded hole in the body into which the tightening screw is screwed. An embodiment with a split sleeve - a clamp or a cut body blows into two identical semicircular bodies, with connecting hinges fitted at one connecting point, but on the other opposite side, a piston-clip, closure or other technical versions of the manual closures may be installed.

Such a conception of the production of fitness equipment, in our case, weights for lifting, and the state of the art is still ruled by the fact that the disadvantage of these and similar systems is that it takes a long time to wind, tighten with springs or piston weights, springs but they smoke on drugs. Namely, the weighting rod is designed so that at least one weighting disk can be mounted on it, with the possibility of adding "n" weighting disks, which means that a very long thread is cut on both ends of the weighting bar.

• · ·

With such long threads, it takes a long time to tighten the nut when mounting one or two weight discs, which is multiplied by a factor of two due to mounting on both ends of the weight bar. When tightening the discs to the suspension rod with the spring buckles, the person must have the greatest power to squeeze the flat levers with one hand and attach the round part of the spring clip to the weight rod with the other hand. Typically, the sleeve sleeves are fast-mounting, but in order to achieve sufficient compression forces of the sleeve and the weighting disk against the milestone, we lack the thrust, because with one hand we keep the sleeve closed, but with the other we perform a closing operation with clips or were closing.

With our patent application, we have modified this system and introduced a system for fast mounting of a weight disk on a weight bar and with our high-speed nut we have updated and technically improved it to such a degree that today we have many individual versions of different dimensional solutions for each weight device, from the smallest to the largest weights. In this context, we have produced design solutions and documentation for all sizes and standard poles to which weight discs are mounted, which are found in various manufacturers of sports equipment.

The present invention relates to a new product, a fast-tightening nut, by which in a very short time or even instantaneously tighten - in the embodiment, according to our patent application - a weight disk to a weight bar.

The quick-tightening nut is conceived in the present version of the patent application as three or more specially designed and constructionally solved jaws, which are circularly connected to at least one spring, which is surrounded by a specially designed crankshaft, which horizontally moves along the part of all jaws. A quick-release nut is a product that will allow the user to attach our nut to the weight rod in a single stroke and to secure the weights or release them in a single motion in the opposite direction and remove the high-tension nut.

So this is a technical solution given in this patent application for innovation, which will shorten the time and simplify the way of mounting and disassembling the weight discs on the weight bar and significantly improve the user experience.

Another essential innovative solution according to the present patent application is in the concept of calipers housed within the crank sleeve, which is provided by the springs which are mounted on the weight rod in the function of opening and closing the clamping nuts of the high-speed nut.

The third technical solution is to locate the calipers inside the crankcase and adjust them according to the technical design of the weighting rod itself. In the case of a round weight rod having a threaded thread, the same thread on the contact wall with the threaded bar weight is also engraved on our jaws. However, in the case of a weighted pole with a smooth circular surface, we use another design concept of the jaw to which a thin rubber layer is vulcanized or any other material having anti-slip properties is applied or glued. In both cases, use a fast-tightening nut that has at least three mother-jaws installed, because testing has shown that the optimum grip of the mother-jaw and the thread on the weight-bearing bar is achieved for the round weight rods if we have a three-point contact of the mother-jaws on the weighting rod.

In order to provide greater safety against the slip of our high-speed nut, we designed the thread through the caliper so that it does not represent its circumference of a uniform radius over the entire circular circle, but deviates by a degree between the beginning and the end of the circumference. In the extended state, it forms a complete circle whose circle has the same center as the inserted pole, except that the diameter of the expanded jaws is so large that it prevents unobstructed insertion and removal of the high-speed nut and enables the pole to grip effectively when closing the jaws.

The next technical solution that rounds out our innovation is the solution of closing and opening, or rather, tightening or tightening. releasing our quick-release nut when in the position where these operations need to be done. This was achieved by designing and conceptually changing the hand bushing, to which at least one or more safety plugs with a dual functional role were installed, in the future being a fuse that closes and opens the jaws or jaws if fitted. there is more, and a final locking element that prevents the composition of the jaws and crankshaft from collapsing. It holds these components together and gives them compactness and ensures the integrity of the assembly proposed in this patent application, but represents a new construction of the high-speed nut.

In order to achieve this and to provide the function of fast-tensioning, we have to adapt this pin and its purpose to the contact part of the jaw and through it - the inner walls, or rather the circular part of the stud, which fits on that part of the jaw. We did this by conceptualizing two guide jaws right next to each other, which are semi-circular shapes, sliding one part of the outer edge of the stud.

From the described embodiment, when we have described and conceptually designed the jaw, the handle bush and the stud, it can be seen that they are functionally adapted to each other and according to all technical rules this system should work.

In order for the system to function and satisfy the technical feasibility of our innovative solution, the question was how and what to do with these three key components - to integrate the elements as a whole. We used the well-known technical element of the spring, which will ensure the closure and opening of our quick-tightening nut and meet the stated goal, which is to find a nut that would be pulled onto any pole and locked with one hand with such force that it would not fall by itself from the pole and in order to prevent it from being removed or failure of other elements, such as in our case the weight disk.

Structurally, on both lateral walls of the calipers, we designed a hole in which a properly sized spring is inserted, thus connecting our calipers in a circle and squeezing them and inserting through the crank sleeve. When the clamped jaws are released, the landing gear on the caliper guide engages the lower round portion of the plug and does not allow it to fall out of the hole in the crankcase.

At the outlet part of the caliper - the contact with the inner wall of the crankcase, on which are carved semicircular recesses representing the guides of the caliper, is a longer recess or the guide is designed as a working guide, through which a plug that is screwed onto the crankcase and its component. In this case, almost two thirds of the conical length of the stud was identified or used. In fact, the working guide must be at least twice the length of the stud, in order to allow the jaws to be opened as much as possible in order to easily pull the fastened sleeve onto the rod. The very contact part of the jaw on which the guides are mounted is oval in shape, following the imaginary cylinder, but it is on this wall of the conical design with a thinner part that goes into the opening of the crankcase and a thicker outer part.

The difference between these thicknesses represents the necessary distance, which allows a sufficiently slight attachment of the fastening nut to the pole or rod and a sufficiently strong compression of the jaws when placing the crank sleeve in the position of locking - locking, in this position it is impossible to slide the nut along the rod or rod.

This is done by rotating it to the left or right, which depends on the concept of making a second recess, in which one hand is moved with a crank sleeve. In fact, we rotate the entire crankcase, which has one or more studs fixed - in the embodiment shown in the sketches, we show three studs mounted on one crankcase, which must also have three jaws.

It all comes down to the innovative concept of jaws when pushing a fast-tightening nut on a bar against an obstacle, a disk and at the first initial pressure the jaws begin to close, which means that the force of the spring regulates the force on the obstacle, in our case the weight disk. It is this innovative note that is unique to us and tested on our model model as the only product known so far, when the jaw encounters an obstacle during attachment and closes as it continues to press, thus fixing the obstacle.

The safety recess or jaw guard is shorter than the working guide and represents the length of the side of the cylinder of our stud, increased by one tenth of a millimeter due to the tightening angle, which can be further made even when the plug has already fallen into the guard bus. This ensures a uniform vertical alignment of the round wall of the crank sleeve and the oval walls of the caliper when the quick-release nut is in the closed - locked position. This gives the product, in addition to its structural precision, the appearance of design and model integrity of beauty and ergonomic utility of the product.

The length of the working guide is also calculated, depending on the dimensions of the stud, cylinder and calipers, so that the vertical alignment of the opposite sides from the already described case is achieved, even when our fast-tightening nut is in the closed - locked position. A very small circumferential ridge is inserted between the work guide and the guard rail, which is designed to automatically prevent the crankcase from jumping with a pin from one guide to the other. The width of this ridge is ever smaller, such as the jaw spacings connected by the springs, allowing them to compress and stretch.

• ·

In the embodiment shown below, we used three calipers housed in a single crankcase, but these can be 3 + n, which can be positioned throughout the circumference of the weight bar or bar. The number of calipers is also determined by the thickness of the rods and rods on which our nut is mounted, as soon as the pole is larger, the nut with more than three calipers is designed. Also, multiple jaws are used on bars that are square or polygonal in shape.

The exact type and shape of the pole or rod determines the ovality and type of contact of the jaw with the pole or pole. When we have a threaded rod, the radius changes in contact, meaning that the radius at the beginning and end is larger than the radius in the middle. The same is true when it comes to a straight stick and we have an anti-slip material applied to the adhesive or a thin layer of rubber is applied through the vulcanization process.

The irregularity of the radius of the oval of the inner or junction walls with the full circumference and the wall of the threaded rod. The straight bar wall allows us to obtain three contact and strength anti-slip points with the high-speed nut, which was taken as a model, with three jaws that can withstand the higher compression forces of these two materials. We have already stated in the text above that, even if the fastening nut is in the locked position, it is technically possible to achieve sufficient moment and tightening force of the nut on the pole by tightening, that is, the joint angular movement of the jaw as well as the hand bushings.

In our case, such a construction of a chystatic nut solved this tightening problem by bending and locking the barrier with one hand movement, and further tightening the jaws. This prevented and prevented the fastening nut from being unscrewed by jumping into the locking groove in the turn-by-turn direction, a lock that prevents the fastening nut from unwinding. The advantage of this is that it takes a minimal amount of time to do the job and we have made it easier to mount the weight discs on the weight bar.

The principle of mounting weight discs on a weight rod is as follows, by having a person take the bar into one of the arms, attach a weight disk to it with the other hand, take the threaded nut and start the process of winding the nut onto the bar thread.

The consequence of this process, especially the negative one, is that, from a timeline perspective, it takes a lot of time and energy to perform this operation. The solution lies in the introduction of our quick-release nut, which we propose in this patent application, and not only in this embodiment, but can be applied to all devices that require a quick coupling of two components.

As a rule, all the nuts of the renowned world manufacturers of fitness equipment of our invention, presented in the present patent application, used the already described system of mounting and execution of their mounting nuts, so that we will not even mention it in the following text, which will prove and implement the defense of our invention .

When developing an innovative idea in the field of patent applications, we have found that there are many different patent applications that mainly relate to different implementations and construction solutions of clamping certain tools, such as. drill bits or certain couplings in the electrical industry that are sealed with insulating material or are self-tightening screw solutions and similar solutions.

To this end, we will present some of these patents, which in our opinion are close to our solution, but which are essential technical features and design solutions that do not concern our innovation as presented in this patent application.

US 4647883 - proposes a self-tightening cylindrical screw into which a expanded and split sleeve is inserted, pressed by a cylindrical nozzle when the nut is tightened to a cylindrical screw

EP 2 136 098 - deals with a self-tightening nut having a circular groove cut into one end into which a single spring is inserted. In this section, at least one elongated slot is incised, which extends when the screw is wound, which enables better nut and screw fixing.

EP 1 287 263 - proposes a self-tightening nut having two clamping jaws, such that a movable two-piece jaw which holds the spring when winding the outer stem part of the plug into the middle part of the inner stem part, thereby hugging and tightening the screw. In this case, it is a nut that is in the function of preventing unwinding and, on the other hand, in the function of providing the necessary twisting forces when hardening two parts.

Λ

Based on the patent application descriptions of the above-mentioned nuts, which are at least classified close to the classification of our quick-tightening nuts, all web clips and sketches show a clearly different construction approach and solutions that are not even similar to our technical solution.

An innovative note of our technical solution, which is technically different from the known, patented and unpatented technical designs and solutions of nuts, anchors, self-tapping heads and fastening nuts, is that we have changed the technology of screwing, which is reflected in the that all solutions used so far use a screw as a driving force that extends certain segments of the nut, thus consolidating its position within the nut. We do not fasten the screw, but by inserting the open nut we reach the end position, rotate the crank sleeve created by the body of the nut, thus locking and fixing the nut on the screw rod or round or. polygonal rods.

To come to this, we did the following:

1. A crankshaft having a cylindrical shape on the outside and a cylindrical conical opening through it,

2. We installed 3 + n calipers in the through hole on the crankshaft, connecting them at least two springs on the sides,

3. the calipers are designed to have two semicircular grooves on the contact side through the wall and the plug, as a working guide for sliding the plug, and a safety guide that locks the plug and thereby also the handle bush.

4. on the opposite side of the contact stand with the stud, but in our case the contact side with the thread of the screw rod or the straight rod was fitted with a thread that fits the thread of the screw rod, or in the case of a flat smooth round or multi-bar, we applied anti-slip material,

5. we used some different materials and techniques that prevent slip and applied them to the contact wall of the jaws with smooth rods, among other we used the application of a thin layer of rubber by the process of electroplating or bonding, in the jaws made of hard plastic, we used the process with which in the case of a hard plastic product, in the process of manufacturing the product itself, in our case of the jaw, is immediately applied a layer that may be of another material, e.g. soft plastic (for better

adhesive) where both materials bond without adhesive and by chemical process, therefore the contact is of the highest quality,

6. Due to the better appearance of our fast-tightening nut, we have introduced in the plastic version the manufacture of crank bushings in multicolor shades according to the procedure mentioned in item 5 above.

It is not possible to prime our product with fastening nuts with other nuts that are designed to tighten weight discs on weight bars because our product does not have a similar product. That is why we made a prototype sample and tested it for the functional and useful purposes already described and proved that our high-speed nut meets all the technical and quality requirements that we set ourselves as a goal to achieve already at the design stage of the product itself.

With these tests and the tests we have done, we have shown that we can even slightly reduce and adjust our quick-tightening nut to the ergonomic shapes of the human wrist, adapting all design dimensions to this set standard, while also saving on the amount of material. This is especially true for the process of tinting our crank bushings and calipers in two or more colors of plastic.

The essence of the technical solution is that, according to our invention, presented in the present patent application, all the known technical and technological findings have been exploited and incorporated into individual versions.

Thus, very precise castings were used for the metal version by microlaying or other casting technologies of various types of metal alloys. We paid special attention to the design concept of integrating the plug into the crank sleeve by also producing a second prototype when the plug was conceived from the same part as the crank sleeve. This simplified and unified the production of the fast-tightening nut, which now consists of only three components of the crank sleeve, caliper and spring.

The continuation of the development path by testing both versions of the fast-tightening nut has led to a new structural, but especially ergonomic change of the crank sleeve, which was added on the opposite side of the perimeter, on which are integrated plugs, nipple projections. The flights are arranged around the circumference of the right part of the crankcase and are arranged in the same circumference of the integrated plug and actually represent its visible half, which is

same dimensions as nipple projections. Namely, nipple protrusions are intended to prevent the human hand from contacting the fastening nut with the disc. So, in order to prevent mechanical damage, the hands are fastened when the nut is attached to the threaded rod or rod.

Tracking the ergonomic suitability of using our quick-release nut has led, among other things, to changing the outer circumference of the crankshaft, which now has nipple bumps and an integrated plug on this side. The change is mainly in the placement of the whole cylinder in a slope at a certain angle, when viewed from the side of the nipple bulge towards the left side of our crank sleeve, we can see the angular slope and thus the decrease in volume on the left side of the crank sleeve circumference.

On the other hand, with our concept of high-speed nuts and the special ergonomic shape of the hand bushing with studs and the three-point placement of the segment jaws and the technology of manufacturing these two key parts, and in the further application of the shown variants and types of anti-slip materials that accompany our product, we We achieved a certain financial burden for our customers by reducing the production costs and the product price - weights by a large percentage, but on the other hand, we raised the technical level of the complete weight, so that with less time consuming, the replacement of the weight disks would be faster.

What is said in the sentences above is true, and it is certainly true that to date no one has made such a design concept for a quick-release nut that, on the one hand, represents ease of manufacture, but on the other hand, provides priming and long-term exploitation in environments where they are used fitness equipment.

Certain design solutions on the jaws and their engagement in the crank sleeve will be described in more detail in the continuation of the file, when describing the individual parts shown in the figure or. 1 and a more detailed view of the concept of mounting the jaws in the through hole on the crankcase and the arrangement of springs thereon, shown in the following figures.

On the other hand, by designing well-known technical solutions of similar nuts at the world level, we came to the realization that our solution is unique and represents a novelty in this field, which is reflected in this patent application and its claims.

The novelty lies mainly in the different design and then the solution of the technical problems that have already arisen in the design process, because the goal was set high, which is the most important feature of the process of conceiving a new way of using a threaded nut, as a fast-tightening nut of its crankshaft with studs and jaws connected by springs. This is externally reflected in the refinement and achievement of the set goal and the technical and technical installation of the jaws, which in its entirety enables opening and closing and locking of the high-speed nut when in the closed position. At the same time it is a highly commercial product and as such has found wide application in all fitness centers and manufacturers of these devices, thanks to unexpected results and properties of usability and quality, so that with one movement of our arm, our fast-tightening nut can be inserted and closed in the desired position.

The invention will be illustrated in Figure 1, which represents a 3D view of our high-speed nut, with views A-A and B-B, in an open state, showing a cylindrical through-sleeve with mounting studs in which the calipers and connecting springs are mounted. The 3D view represents the basic sketch for which we made a prototype prototype and further, in Figures 2 and 3, we will show the front and side views of our quick-release bush, with the technical solution of mounting the jaws into the through hole on the crankcase.

Further, in Figures 4 in the open state and 5 in the closed state we will show a side cross-section of our quick-release nut with all the technical solutions of the tapered through sides of the crankcase and caliper and the insertion of the plug on the crankcase. In Fig. 6, we highlighted the C-C view of Fig. 5, which tells us and shows the appearance of the fast-locked bush in the locked state, but in Fig. 7 below, we show a 3D view of the assembly or assembly of the three jaws associated with the springs and the D-D and E-E views. We will take a closer look at these and describe them in Figures 8 and 9 and touch on the design of the stud shown in Fig. 10. In the following description of the pictures and proving the patentability of our innovation, we have shown in Figures 10 to 14 one of our quick-release nuts for round or polygonal rod materials with a smooth surface and no threaded thread.

Continued development has led to a desire for ergonomic - design solutions that have made the product even more expensive, such as improving the grip and safety of the human hand when it comes to fastening our high - speed nut to one of the rods or rods already mentioned.

These construction solutions can be seen in Figures 15, 16 and 17, where we integrated the stud into the crank sleeve and added nipple projections to it and placed the outer body shape in a tilt from right to left.

For a better understanding of the foregoing brief description of the basic sketches of our innovative idea, which is manifested in the form of a high-speed nut and its basic assemblies as a percussion product, formed on the basis of the design of our innovative idea shown in this patent application and its drawing, which will be incorporated herein by reference. described below.

Now let us return to the essence of our innovative solution, which we have illustrated in a structural way in Figs. 4, which represents the lateral or lateral cross-section of the fast-tightening nut in the open state, with all the structural and technical data shown, which serve us to better understand the technical implementation itself and the ease of our innovation. The handle sleeve 1 is on the outside of a circular shape having a tapered opening in the through portion - hole 1.3 FIG. 10 bounded by the right conical circle 1.3.2 and the left conical circle.3.3. The transitions between these tapered lines are connected by the straight-through horizontal circle 1.3.1 shown in FIG. 10. Both tapered lines 1.3.2 and 1.3.3 and their inclination toward the edge of wall 1.4 determine the angles β and γ, which simultaneously represent the taper angles of the through side through the opening 1.3 of the crank bush 1 and the contact side 2.6 of the plug 2. Angle line β at right conical round 1.3.2 always comes from the right side of the crank 1 and at the same time represents approx. 2/5 of the total through length of the crank bush 1. Meanwhile, the line of the left conical circle 1.3.3, which it defines as γ, represents the total length of the through line 1.3 of Fig. 10. The remaining length, however, represents the length of the straight or horizontal through-circle 1.3.1. 10.

Seen on the left side of the crank sleeve 1 fig. 4, this is the last lateral side 1.5.0, which has no incised square - rectangular openings 1.1 FIG. 10 for the bushing 4 shown in the several figures appended to the present patent file, the total length of the conical circle 1.3.3, which it defines as β, is at the same time a milestone preventing the loss of the composition of three or more jaws 2. Crossing the line of the conical circle 1.3.3. In the plane horizontal section 1.3.1. Through the walls of the crankcase 1 FIG. 4 actually represents a milestone that inserts the jaw assembly 2 at closing, but the locking of these will be described in the description of the drawings 5 to 9. The angles β and γ are conceptualized between 5 ° and 40 ° when viewed from the horizontal axis and may be the same, but under exceptional technical conditions defined by the type of material used, a deviation of angle β by 0.5 ° to a maximum of 1 ° may be allowed. This is especially true for materials that can change their dimensions at operating temperature, thus expanding and shrinking.

Right Side View 1.5.1 Side Bushings 1 Fig. 4 and 10, this is a side having incised squares - rectangular openings 1.1 FIG. 10, which are arranged around the circumference 1.5.1 according to the number of jaws 2.

·· ·

In our three-jaw embodiment, 120 ° are the distances between the rectangular bores 1.1 having threaded holes 1.2 in the center of the circumference and a precise radial distance of 120 °, into which a pin 4 is screwed with a 5-point screw. 4, but is further elaborated in FIG. 11. In fact, this is a circular cylindrical part 4 of FIG. 11 having a through hole 4.1 which is adapted to the standard screw 5 of FIG. 4 with a flat head engraved having a crack or a hex connection for turning and unwinding.

The contact portion 4.2 of the plug 4 shown in FIG. 11 and all the other images in which it is seen are screwed, drilled using a screw 5 into the threaded hole 1.2 at a rectangular notch 1.1 on the crankcase 1, framed and smaller by 0.5 to 1 mm from the edge, which has a tapered hole for the screw 5 with the head engraved. We did this to make plug 4 easier to insert into a rectangular cut

1.1. On the crankcase 1. This particular part or bottom of the rectangular bore 1.1.1. At the perpendicular notch 1.1 of the crankcase 1 has a threaded hole 1.2 in the center, into which the stud 4 is screwed with a screw 5, designed and constructed at an angle δ. , which represents the angle of insertion and tightening of pin 4 on the crankcase 1 FIG. 4. The angle δ tilts toward the outer wall 1.4 of the crankcase and is required to create a smaller ridge 4 with a pin 4 - a barrier which, after inserting the jaw assembly 2 into the through hole 1.3 on the crankcase 1, is screwed onto it and thereby obtained dual function. First, it prevents the jaw assembly 2 and springs 6 from falling out of the through hole 1.3 on the crank sleeve 1, and finally the mounting pin 4 on the crank sleeve 1 forms a new assembly that clamps and holds together the entire quick-lock nut and allows it to be unlocked and locked.

In the continuation of describing the individual components of our quick-tightening nut, the jaw 2 of Figures 7, 8 and 9 is a key part, which is in the function of vertical movement when unlocking and locking our nut. In Fig. 7, we show a 3D view of an embodiment of the present patent application, three interconnected springs 6 of the jaw 2. At the joint part of the jaw 2 with the through hole 1.3 already described, the wall with the same angular displacements β and γ is derived, as there are 1.3 crank bushings already described through the wall. So this is a mirror image of the lines and angles described above, so no further clarification and description is needed because we have said everything when describing through wall 1.3 on crank 1 and the course of its lines 1.3.1.

1.3.2 and 1.3.3 bounded by the angles β and γ.

On this side of the jaw 2, ie on the contact side of the plug 2.6, through the wall of the crank sleeve 1 and the plug 4, the jaw 2 has two semicircular grooves, namely the working guide 2.1, which slides the plug 4, and the safety guard 2.2, which locks pin 4 and thereby the crankcase 1. Both guides are open on the inlet side, but terminate on the diametrical side with a guide 2.1.1 of the guide 2.1 and a guard 2.2 of the guard 2.2, which function to prevent disintegration of the compressed jaws 2 inserted into the through hole 1.3 FIG. 10 crank bush 1. So all three jaws are 2 fig. 7 and FIG. 8 is a D-D view in the prestressed state and is provided by the springs 6 shown in almost all pictures of the present patent application.

Working bus 2.1 represents almost two lengths of safety bus 2.2, which is 0.1 to 0.5 mm longer than the length of the plug cylinder 4. With this conception and proportion of lengths, we ensured the smooth opening and closing of our quick-release nut, but on the other hand we provided it with a vertical alignment of the panels on the right - the working side of both the jaw components 2 and the circumference 1.5.1 on the crankcase 1 shown in most of the figures enclosed in this patent application. A millimeter circumferential ridge 2.0 is installed between the working guide 2.1 and the guarding 2.2, which is designed to automatically prevent the leakage of the crank sleeve 1 by plug 4 from one to the other guide. The width of the ridge 2.0 should always be smaller than the spacing 2.5 between the jaws 2, which are connected by the springs 6, thereby allowing them to compress and stretch.

In the following description of the jaws on the diametrical side of the contact side of the stud 2.6 and through the opening 1.3 of the crank sleeve 1, in our case, the thread of the jaw 2.3 is shown. 7 and 8 with contact side or. thread thread 3, we placed thread 2.3 with an uneven thickness 2.3.1 along the inner circumferential Ri and R2 of the jaw radius 2. This thread 2.3 fits into the thread of the threaded rod 3 or in the case of a flat smooth round or polygonal rod, the anti-slip material 7 is shown. in FIG. 12, 13 and 14.

Exactly the type and shape of the pole 3 sl.l or bars 3.1 sl. 12 and 3.2 FIG. 14 determines the ovality and the type of contact wall of the jaw 2 with the threaded rod 3 of FIG. 1 or smooth round rod 3.1 FIG. 12 oz. polygonal smooth rod 3.2 FIG. 14.

When a threaded rod 3 is provided, the radius R1 and R2 of FIG. 8. These are the radii of ovality of the inside of the contact wall of the jaw with a threaded 2.3, which means that the radius R2 at the beginning is smaller than the radius Ri at the end, which is reflected in the different thickness - the depth of the incised thread 2.3.1.

These are micron differences, defined as a, which is a degree difference between 0 ° and 3 ° between Ri and R2 and is called the radius of ovality of the thread 2.3 on the jaw 2. This is especially necessary to tighten our quick-release nut when placed on the crankshaft 1 plug 4 into locking position 2.2 and if we still have the strength, screw the entire nut by a quarter, half a circle, and then complete the process of tightening our nut to the weight disk.

This means that if the fastening nut is in the locked position, it is technically possible to obtain sufficient torque and tightening force of the nut on the rod by tightening, that is, the joint angular movement of the jaw 2 as well as the crank bush 1. This unevenness of the radii Ri and R2, the oval of the inner thread 2.3 with the full circumference and the wall of the rod with the thread 2.3 or. The wall of a straight bar allows us to obtain six contact and strength anti-slip points with the three-caliper 2, which has been taken as an exemplary model, which have greater compression forces of these two materials.

In Figure 13, F - F view, Ri, R2 and R3 are the radii of ovality of the inside of the contact wall of the jaw, which does not have a threaded thread on the round bar, but Ri and R2 are the same, but R3 is a few tens of millimeters smaller because this part 7 is made of a special anti-slip substance, which we have already stated in the present text, which, when tightening the already closed fast-tightening nut, is compressed so that this thickness is equal and a uniform radius is obtained throughout the circumference. However, in the embodiment shown in the accompanying drawings, no circular grip with their radii when closed is formed in the composition of the three jaws 2.

Namely, the radius R1 of the jaw 2 represents in the middle of the circumference defined by R2 of FIG. 8, reduced by the angle a, which does not form an ideal circle in the global composition of the three jaws. With this polarity, we have achieved a better grip of the jaw 2 on the threaded rod 3 or. bars 3.1 and 3.2.

• · ·

This gives us a complete grip on the rod and maximum torque of our nut to the round smooth rod 3.1 Fig. 13.

The following is a description of the design concept of the jaw 2 FIG. 8 of our high-speed nuts, we need to describe the two sidewall surfaces 2.4 on the jaw 2, which have four 2.4.1 bore holes intended for spring insertion. Two to two bores 2.4.1 are joined to the bores on the adjacent jaw 2 by inserting one spring 6 in each of the two bores 2.4.1 shown in FIG. 1, 2, 4, 5, 6, 12, 13 and 14. The size of the holes depends on the construction and load of our quick-release nut, so that the weight of each weight disc determines the concept of not only springs 6, but jaws 2 as well as crankshafts bushings 1 and studs 4.

Figure 9 view E - E represents a lateral view of one jaw 2, with a focus on the gap - the distance between adjacent jaws 2.5 or the space between the jaws 2 required to compress and open jaws 2. Namely jaws 2 are inserted into the through opening. 1.3 crank bushings 1 and are always in a certain spring tension but. When the jaw 2 is closed or, better said, locked, see pin position 4 fig. 6 located in the guard rail

2.2, the spring 6 is in a compressed state at that time, with a large overvoltage force. In this position, the gap 2.5 between the jaw walls 2 must be greater than or equal to the width of the ridge 2.0.

This is because the passage of the plug 4 from the open state of the working guide 2.1 to the closed locked state into the guarded guide 2.2 via the ridge 2.0 may not be shorter than the air distance 2.5 between the interface walls of the jaw 2 FIG. 6 and 9. If this happened, then it would not be possible to tighten the jaw 2 around the screw rod 3 or the straight 3.1 or multi-bar

3.2.

On our new product (s) made according to the present patent application, as a prototype for the testing shown in Figures 1, 12 and 14, made of plastic, we had to optimize all three key components of the crank 1, the caliper 2 and the plug 4 for all three phenomena. shapes of weight bars 3, 3.1 and 3.2. The design concept for polygonal rods applies

3.2 fig. 14, a technical solution for the placement of the anti-slip material 7 as a deposition of a flat substance on a contact wall 2.3.2, which was so numerically attached to the threaded wall 2.3 FIG. 7 and 8.

In FIG. 15 we paid special attention to the implementation and construction concept of integrating pin 8 into the crankcase 1 by also producing a second prototype, where the pin 8 is conceived from the same part as the crankcase 1. When we talk about integration, we primarily mean that we have produced a hand bushing made of one piece, whether plastic or metal, or any other material that is suitable for the manufacture of the product concerned. The current integrated plug 8 FIG. 15 is structurally conceived as an elongated half of the pin 4 shown in all figures up to FIG. 15, which is best seen in view G - G of FIG. 16, under the new number 8 and view H - H in FIG. 17, which illustrates a lateral view of the newly designed crank sleeve 1 shown in FIG. 1.

In the tests of the two prototypes shown in Figures 1 to 14 with the mounted plug 4 and Figures 15 to 17 with the integrated plug 8, it was found by testing both versions of the quick-release nut that it is necessary to protect the human hand when attaching the quick-release nut to the rod 3 fig. 1.

This led to a new structural, but especially ergonomic change in the crank sleeve 1, to which the nipple projections 9 shown in FIG. 15 and 17, on the opposite side of the circumference 1.5.1 of FIG. 15, with integrated plugs 8. These nipples 9 are shown in FIG. 17 are arranged throughout the circumference of the right part of the crank bush 1 and are arranged in the same circumference of the integrated plug 8 and actually represent its visible half, which is the same size as the nipple projections 9.

The point of these nipples 9 is that they are designed to prevent contact between the disc and the human hands while attaching the quick-release nut to the rod 3 FIG. 1. Therefore, in order to prevent mechanical damage to the hands, the fastening stroke of the nut on the threaded rod is 3 fig. 1 or rod 3.1 shown in FIG. 13 oz. 3.2 fig. 14.

The continuation of the development of our fast-tightening nut is reflected in the ergonomic suitability of the use of our quick-tightening nut, which has led, among other things, to changing the outer circumference of the 1.4 crankshaft 1 Fig. 15 and 16, which now has nipple projections 9 on this side and an integrated plug 8. The change is mainly in the layout of the entire crankcase roller 1 in FIG. 1 in a slope at a certain angle ε, which is maximally set to 8 °.

Seen from the side of nipple projection 9 towards the left side of our crank sleeve 1 fig. 16 view G - G, one can see the angular slope ε and thus the smaller circumference on the left side of the crankcase 1.

This simplified and unified the production of the fast-tightening nut, which now consists of only three components of the crank sleeve, caliper and spring.

Above we have described the specific parts of our high-speed nut, with prototypes made according to the present patent application, and it really appears with the key parts already described, which we have presented in both embodiments and supported by the attached sketches and its detail views A, B, C , D, E, F, G and H.

The exemplary examples illustrate a quick-lock nut having a crank sleeve 1 into which three or more jaws 2 are inserted which are in tension with each other due to the intermediate springs 6 which maintain this tension because they are always in a certain compressed state.

The compact system gives the plug 4, which is quantitatively tied to the number of calipers 2 and screwed into specially rectangular openings made on the crankcase or the integrated plug 8, now seen as an integral part of crankcase 1. They are intended to prevent the system from falling apart and is at the same time in the function of opening and closing the high-speed nut proposed in the present patent file.

A summary of the principle of operation of all the above parts is that with one hand we place our quick-tightening nut on one of the rods and tighten it slightly with the right and lock it against the weight disk. This is why our system takes precedence over existing ones, because in a very short time interval we can replace the weight disk and focus on fitness exercises rather than long-term tightening or loosening of existing nuts for fitness equipment.
