たない事を現状とするものである。2. Description of the Related Art A screw is originally a fastening member that utilizes a thread groove, so even if a screw is used to fasten objects to each other, the surrounding environment, that is, the vibration affected temperature It is impossible to cut off the edge from the fate that it surely loosens due to problems such as differences, for this reason, such as double lock, eccentricity, crushing, groove splitting, pinning, embedded resin, At the end of the phrase, the fact that fitting and rubbing such as welding after screwing has been repeated in the history of more than a century has been repeated. What you have and what is the solution to loosening! Despite the problems that have been considered with such importance, all of them are just means of quick reluctance as merits and demerits or merits and demerits, let alone their effective decisive strokes. It is the actual situation that the actualization of such means and methods, etc. has not yet led to this finding.
It means that the return path of the screw is always open as long as there is no deterioration of the screw due to the condition or welding. Furthermore, in the present situation, there is no way to deal with forgetting to tighten the screw, and there is no method other than repeated "confirmation tightening".

In other words, what is sought there is the establishment of a certainty function as a screw fastening and the basicity of its loosening prevention structure, and a screw forgetting prevention device which considers this as a functional structure.

のである。[Means and Actions for Solving the Problem] First, when thinking about the completeness of screw fastening, the ultimate is immediately to think strongly about the basic element that is connected to the loosening prevention effect of the screw itself. It is a thing. Therefore, from the finding that tightening and loosening can be realized only in the unity of the front and back, we considered that the unity could be introduced into this development measure. Furthermore, I think that the prevention of forgetting to tighten the screw is not the "repetition of confirmation tightening" that has always been carried out in the past, but the development of a "certainty device" for tightening that can be visually confirmed. In the past, it was a matter of messing around with the nut itself or the bolt itself, that is, the damage to the screw itself is one condition because it is too much to think about the completeness of screw fastening and its locking. This is admitted as a stop, and the fact that the method considered on that accounted for almost 100% of the cases is the fact that if there is a method that is not so, the only "double "Tightening by nut system" I think that this is the only thing that I think of, but this is no matter how you think about it, it is "screw fastening by palliative means" that combines objects and Tsujimi as a screw with a "fastening task" This is the place where you cannot help but think of it as "preventing its loosening." Furthermore, there is no decisive factor in dealing with forgetting to tighten the screw, and this is left as it is without any solution because of the "extremely uncertain adherence" that is peculiar to screw tightening. In addition, it is said that there is only "uncertain confirmation tightening". Therefore, when thinking about the thorough pursuit of its safety in regard to forgetting to tighten the screw, it is necessary to pursue the functionalization of "keeping evidence of tightening together with its actuality". As the screw is tightened by the female and male screw engagements due to the beveled groove engraved in it, and the tightening force is applied to the object, it is natural to return to the path that goes forward. It is said that it is a fatal defect to loosening, so the basic principle of loosening prevention is only one, and it is an exaggeration to say that there is no measure other than "blocking the return way" after the conclusion of the fastening It is not a matter of course, however, that it is not possible to use a technique such as welding, but to find the structure of the function that serves as the principle of loosening based on the intention to loosen it. is there. Therefore, the present invention was conceived on the basis of a sand of a pressure spring in which two right-handed and left-handed two-system two bodies were used, and the completion of ternary fastening and looseness (looseness) due to this were considered. It is different from stop). Further, regarding the device for confirming that the user has forgotten to tighten it, the three-lock structure of the present invention of a composite screw assembly having a structure not used in the past for screw fastening is used as a part of the fixed body and the other part is rotated. Each point considered as a moving body structure is provided with its point affix, and the matching is used to confirm whether or not this tightening is forgotten.

めるものである。DESCRIPTION OF THE PREFERRED EMBODIMENTS First, in this embodiment, the nut system and the bolt system according to the present invention are made to have the same functions. Now, the nut system will be described with reference to FIG. The cross nut (a-1), the pressure spring (b), and the crimping nut (c) according to (3) above, which are assembled according to the required pressure with the above three points, are used for fastening as this nut set. First, bring this to the fixing surface by hand tightening via bolts, and then cross nut (a-1).
When it is used with "usually general tightening" depending on the tightening of spanner, the cross nut (a-
1) The tightening of the bolt against the bolt starts, and at that time, the pressure friction on the fixing surface of the crimp nut (c) is almost at the same time, until the pressure spring (b) is sanded and the left-hand screw is screwed. The unwinding action was maintained between (a-1) and (c) (the cross nut (a-1) was tightened to the right against the bolt, and the fixing surface resistance was generated in the crimp nut (c). Depending on the faction,
(A) (c) Separation action for both left-hand screwing) works, and at the same time, the "separation energy" is the crimp nut (c).
Then, energy conversion to straight down, that is, pushing down, is performed, and the cross nut (a-1) is tightened against the bolt and the crimp nut (c) is used to straightly crimp the fixed object. … Completed in that duality. However, at this time, the unwinding action between the above (a-1) and (c), the tightening rotation of the cross nut (a-1), and the expanding action that has been fastened at about 1/8 of the rotation of the pair (c) ), The distance between (a-1) and (c) will be somewhat widened by that amount, but due to the anti-torque of the pressure spring (b) pre-sanded here, the simultaneous advancement is compensated. The above is the end of everything related to this fastening action in terms of its ternary nature. This is because pulling and tightening of the counter bolt by rotating torque and straight fixing to the objective are both right and left bodies. It is ended by the bipolar action by using both screws, and the double pressure clamping action here and the cooperative action of the pressure spring added to this are great and proud of the absoluteness to that effect. Is. When the loosening of the screws due to the influence of the natural environment or the like occurs in the paddy field, what is the function of each part due to the loosening? When the cross nut (a-1) tries to release from the bolt tightening, this naturally becomes a counterclockwise action, but it is not fixed and it is against the crimp nut (c) in the left screw engagement. The tightening action of the pressure spring (b) sandwiched there is much less, and the "normal interference" of the loosening action is achieved due to the inhibition of the reaction force of the pressure spring (b) sandwiched there. Relationship between straight direct pressure bonding (without friction track when tightening) when fixing
Of course, it is impossible to re-tighten the cross nut (a-1) due to the left-hand thread engagement (the pressure spring is also effective). It has become. However, this does not affect the loosening by artificial operation. The function of this special nut according to the present invention depends on the combination of the left and right screws, and the pressure spring is placed in the middle of this based on the characteristic function of the connecting relationship, that is, open when tightened, and close when loosened. It was possible to seek the possibility of idealization by sanding. This is the nut system of Fig. 1 (1), the bolt system of (2), both types, the same interpretation can be established with the same basics. Is.

If there is no misalignment between the marks due to the matching mark matching between this and the pivotable mating point due to the set structure, tightening is forgotten, and if the mark misalignment is recognized as in (3), It is confirmed that it has already been tightened.The pivotable mating point is set with a matching mark set in series with the fixed point when setting this nut assembly. is there.
As described in the preceding paragraphs, the crimp nuts (c) are basically fixed as a non-rotating straight down at the time of fixing. By tightening (a-1) of the nut (1) and (a-2) of the cross bolt (2) (matching mark), the tightening and forgetting to tighten can be confirmed. By the way, the completion of fastening can be measured when the movement difference (mark deviation) during fastening with (a-1) and (a-2) stays within approximately 1/8 to 1/6 laps.

In both cases, the tightening action is "backward binding. The pressure spring is planned to be placed there to utilize the resilience to both screw structures and to prevent its loosening. Furthermore, one of this double screw structure is not fastened (straight) Down), the other is turned and tightened (screw tightening), and in this static and dynamic tightening operation, the mutual relationship is displaced and it is possible to visually judge that the screw is forgotten to be tightened. As described above, this characteristic structure provides an unrivaled fastening ability, its loosening function, and thorough prevention of forgetting to tighten.
