DE20320167U1 - Snap hook has spring-loaded lock which fits into its base and push button mounted on threaded pin which fits through bore in lock into recess, into which stop fits which locks hook - Google Patents

Abstract

The snap hook has a spring-loaded lock (3) which fits into its base. A push button (4) is mounted on a threaded pin (41) which fits through a bore (32) in the lock into a recess (31) in it. A stop (5) fits into the recess and the pin is screwed into this. It can be turned using the button to lock the hook.

Description

technical area

The invention relates to a hook with a bolt, a stop being provided in the bolt, the can be turned out of the bolt when the hook is locked, so that the hook can be accidentally released by an external force can be avoided.

State of the art

The hook with a bolt will be applied to different objects, such as a lanyard, key ring, collar, jewelry band, etc. In 6-A and 6-B A conventional hook A with a bolt is shown, which is designed in the form of a question mark (“?”) and has a receiving space A1 in which a bolt C and a coil spring B are received. The wall of the receiving space A1 is provided with a slot A2 A push button D is passed through the slot A2 and connected to the latch C. In the normal state, the latch C is in contact with the end A3 of the hook A because of the coil spring B, so that the opening of the hook A is closed D is pressed downward, the latch C is also moved and compresses the coil spring B, thereby opening the opening of the hook A. However, the push button D can be accidentally pressed down by a cord E or an external force, so that the object F emerges from the hook A.

When object F is pulled, as in 6-D is shown, the bolt 3 are loaded by the tensile force on the object F. However, stress concentration may occur at the two corners A21 of the lower end of the slot A2, causing the slot to break 12 can lead.

Task of invention

The invention is based on the object to create a hook with a latch that is an accidental Unlocking the hook can be avoided by an external force.

This object is achieved by the hook according to the invention solved, which has a receiving space in which a bolt and a coil spring are received are, wherein the wall of the receiving space is provided with a slot through which a push button is passed and connected to the bolt is characterized in that the bolt has a recess, the one with the hole for the push button is connected and in which a stop is provided is, and the push button has a pin that ends with a external thread is provided, wherein the pin is passed through the hole of the bolt and the external thread is screwed into an internal thread of the stop. If the catch is locked, the push button can be turned, whereby the Stop emerges from the recess in the bolt and onto the face rests on the wall of the receiving space, so that the latch and thus the push button can no longer be pressed down.

The invention is another Task to create a hook with a bolt that a stress concentration on the slot by a tensile force can avoid by rounding the lower end of the slot.

Ways to Execute the invention

How out 1 and 2 can be seen is the hook according to the invention 1 in the form of a question mark ("?") and has a recording room 11 on in which a latch 3 and a coil spring 2 are included. The wall of the recording room 11 is with a slit 12 Mistake. A push button 4 is through the slot 12 passed through and with the bolt 3 connected. The bottom end 121 of the slot 12 is rounded. The bar 3 has a recess 31 that with the hole 32 for the push button 4 connected is. In the recess 31 is a stop 5 intended. The push button 4 assigns a pen 41 on that ended up with an external thread 42 is provided, the pin 41 through the hole 32 of the bolt 3 passed and the external thread 42 into an internal thread 51 of the attack 5 is screwed in.

To unlock the hook 1 becomes the push button 4 pressed down, causing the latch 3 is also moved and thus the coil spring 2 pressed together ( 3 ) so that the opening of the hook 1 is opened. Therefore, an object F can be caught 1 enter. Then the push button 4 be released, causing the bolt 3 because of the restoring force of the coil spring 2 in the recording room 11 is pushed up so that the opening of the hook 1 is closed ( 4-A and 4-B ). Therefore, the item F in the hook 1 limited. Now the push button can 4 be rotated so that the stop 5 out of the recess 31 of the bolt 3 emerges and on the face of the wall of the receiving space 11 rests so that the latch 1 and thus the push button 4 can no longer be pressed down. This can inadvertently unlock the hook 1 by an external force on the push button 4 be avoided.

When object F is pulled, the latch can 3 are loaded by the tensile force on the object F. Through the rounded lower end 121 of the slot 12 can have a stress concentration on the slot 12 avoided so that a break in the slot 12 can be prevented.

Due to the above facts corresponds to the invention in its availability, progressiveness and novelty fully meets the requirements for a utility model.
