Quick release nut

The invention relates to a keyless chuck with SWEi shell-shaped £ eilstüeken _s AEIE near a ünde threaded rings having ₉ in the assembled piece of rope "n to the nut thread comple"

-during the. remaining sections of the part »stüoke a through hole relatively large Form diameter ^ with the parts in the area the through hole articulated with one another connected and their thread by unfolding about an axis parallel to the plane of division from the The threads of a screw can be swiveled out ο

Üine known quick-locking nut of this kind has a the two half-shell-shaped portions adjacent to the thread perpendicular zvlt I'eilungsebene penetrating, conical bore ₉ in which it gets inserted in front of the Ansi away the nut is a conical pin so as the thread of the two parts into engagement with the thread of the Hold the bolt on which the nut is tightened. On the side facing the nut's abutment, the two halves each have semicircular attachments that complement each other in a ring. "An annular washer can be placed on these attachments instead of the pin to hold the nut together."

This well-known quick release nut has the disadvantage

® oiler pin and the corresponding © hole must be worked very precisely ₉ because the Muttes ^one else dureh at Ansi marriages ß-ewinde of eatsprechenden threaded bolt is gespreist and not äaim more _s grabs When Sp ^ eisea eggs mother came the pin bend ^ Sun that it can then no longer be pulled out of the bores. Furthermore, inserting and removing the pin takes a considerable amount of time. Also, a wrench can me be sohlecht attached to the hexagonal nut ₉ since the pin in the region of the thread AUB protrudes two surfaces of the nut ", since the ge = ieakige Yerbindimg of the two cable parts ä approximately midway © r nut is provided and with the thread The provided section of the nut is spread when the section facing the through-hole is pressed together? / is _{9 the} attachment of the external wrench w & T a small attachment of the connection of the two rope parts "and the pin available ο a disk used instead of the ötiftee , B ä®n exactly on the tob. halblErelsförmigea gebil- approaches

Be careful ₉ so that the nut is not spread apart when tightening ο Placing the washer on the llnj is very difficult, especially since no means are provided for centering the washer when placing it _o In particular ₉ when the nut is in use over its abutment is arranged ρ the disc must be held by special means »so that it does not gate the tightening of the nut King

"An essential part laughing OCE known mother ordered it ^ öaß you by!. Flat abutment hat aa one point rests and dali-ei? only a portion of the mother charged wircL This may SU violations of the G-ewlndes and also m a bending of the pin lead "

J5s is also a tapered threaded sleeve known to split along its longitudinal axis in two

in

ÜJeilstüeke divided and / one provided in a stamp conical bore is fitted. For the festival ^ To screw an object onto the carrier, the threaded bolt inserted through the conical bore must be axially positioned after the threaded sleeve has been placed Sighting can be postponed until the Ge · = thread sleeve is pulled into the conical bore, otherwise the two halves of the sleeve will fall apart again would. Only then can the bolt be tightened »This threaded sleeve can therefore to be used only in such cases ^ where the bolt is rotatable and displaceable in the axial direction ο

Furthermore, an undivided quick-release nut is known whose threaded hole is a lateral one Has extension without thread "so that they in an eccentric position without rotation on the Screw bolt is slidable »The nut is conically tapered at one end »This taper fits into a conical bore of a washer, in which the screw nut is centrically

leads ₉ with its thread »into which engages the screw bolt This nut has the drawback that their .Belastbarkeit actual result of the formed only over a semicircular thread greatly reduced Also, the washer _P will be the play fitted on the Schraubbolsen, MUB" on. the side opposite the thread of the nut is printed against the thread of the bolt ₉ which can damage it «

The invention is based on the object _{9 of} creating a son clamping nut ₉ in which the disadvantages of the known nuts are avoided

The invention consists in that the thread of the nut is arranged in a towards the end conically tapered section "The Yorteil of the invention is ₉ that no special parts sum of the nut holding together are required" The two I mother eilstücke are first through the Wrench held together and then automatically compressed when the nut is tightened by a corresponding abutment on which the nut comes to rest5 »The abutment

needs dasu merely the tapered portion approximately corresponding recess aufsuweisen "This brings an essential Zeiteinspa- jcvpoQ when tightening and loosening the nut to be ₀ is as abutment a washer 9 is used so it is not necessary ^ that .these play sitting on the Bolsen ο When the nut is attached, the washer centers itself so that the bolt thread cannot be damaged opposite points are loaded »if the counterpart is uneven» This means that both parts of the nut are always stressed essentially evenly »

In one embodiment of the invention, the pivot axis is arranged in the parting plane of the nut and the both 'parts' have the same porm = thereby the production of external clamping nuts is much easier * The parts of the nut .sind are preferably provided with lugs that overlap and one with the other have aligned bores ^ in oils a bearing pin

is plugged in o'Thereby, each part has an outer piece on a border of the surface facing the rope level ©. Approach and an internal recess and aia the other edge an internal approach uni an ■ externally lying β recess ίϋτ the approach of the counterpart,

In a preferred embodiment of the invention that is the nut ver ~ binding joint close to the arranged, the two cord pieces the nut thread repellent end of the through hole IJies has the substantial Yorteil _s that the wrench apart from which kegelig- ver = · young portion, at every point the mother can be set.
