Description

Technical area

The The invention relates to an umbrella, in particular a safety device for automatically foldable and foldable umbrella.

State of the art

Of the automatic umbrella can be opened and closed by pressing a button be folded and thus has an easy handling on.

Out CN2476208Y from 13.02.2002 a control device for automatically folding and folding umbrella is known. When unfolding the umbrella will be a button 60 ' pressed, causing the stick 50 ' solved and by a Aufspannfeder 51 ' is rebounded. When folding the umbrella, the button becomes 60 ' pressed again, creating a hook head 523 ' on the floor 50 ' is released, so that the umbrella fabric by a Zuspannfeder (not shown) is clamped and the hook head 523 ' from a string 522 ' in the upper area of the floor 50 ' is pulled. After that, the stick becomes 50 ' in the direction of the handle 110 ' against the spring force of the Aufspannfeder 51 ' pressed to the stick 50 push together until the stick 50 ' and the hook head 523 ' again from the controller in the handle 110 ' is locked.

A similar control device for automatically foldable and collapsible Umbrellaist z. B. from the Chinese patents, such as 01217730.X . 01237609.4 . 01262761.5 . 03267824.X etc., known.

These Control device for automatically foldable and foldable However, umbrella has the following disadvantages: The Aufspannfeder has a strong restoring force. When pushing together of the stick, the compressive force on the stick must be the spring force Override the clamping spring until the stick is locked. Since the spring force of the Aufspannfeder is large, the Stick not even pushed together. When the stick is traveling is released, the stick can be rebound by the Aufspannfeder become. This can lead to injury to the user. Therefore, the inventor aims to solve this problem.

Object of the invention

Of the Invention is based on the object, a safety device for automatically foldable and foldable umbrella to create a rebound when folding the umbrella of the stick can prevent.

These The object is achieved by the safety device according to the invention for automatically foldable and foldable umbrella solved having a main body in the handle of the umbrella comprising an axle, a ratchet, an elevator spring, a locking element and a cord, wherein the axis stored in the lower part of the main body is connected at one end to the ratchet and at the other end to the elevator spring which is attached to the main body, with the ratchet having a plurality of teeth, wherein the blocking element attached at one end to the main body, at the other At the end a free end forms on the teeth of the ratchet is aligned, and forms a projection on the inside, through a through hole in the side wall of the main body protrudes into a hole in the main body and on the receding Hook head is aligned, and being the cord with one end attached to the axle and with the other end attached to the crown.

Between the locking element and the inner wall of the handle is a leaf spring arranged through which the free end of the locking element in the teeth the ratchet engages.

Of the Hook head is provided with a through hole through which the cord is guided.

At the The stick is pushed together by the elevator spring rolled up on the axle. When the pressure on the stick disappears, A reverse rotation of the axis is prevented because the free Engages the teeth of the ratchet end of the locking element, so that the crown is held by the cord. This will a rebound of the stick prevented by the Aufspannfeder so that when pushing together the stick avoided injury can be.

Ways to execute the invention

in the The following is the invention with reference to a preferred embodiment explained in more detail.

Like from the 2 and 3 As can be seen, the invention comprises a main body 2 in the handle 11 of the umbrella, which is an axle 3 , a ratchet 4 , an elevator spring 5 , a blocking element 6 , a leaf spring 7 and a string 8th having.

The main body 2 in the handle 11 also has a control, which does not belong to the subject invention and therefore not described in detail here. The main body 2 is with a hole 12 for the stick 12 provided in which a hook head 9 is provided.

The axis 3 is in the lower part of the main body 2 stored, at one end with the ratchet 4 and at the other end with the elevator spring 5 connected to the main body 2 is attached. The ratchet 4 has a variety of teeth 41 on. By the elevator spring 5 can the axis 3 to be turned around.

The blocking element 6 is with one end on the main body 2 attached and forms at the other end a free end 61 that on the teeth 41 the ratchet 4 is aligned. The blocking element 6 forms a projection on the inside 62 out through a through hole 22 the side wall of the main body 2 into the hole 21 of the main body 2 sticks out and on the receding hook head 9 is aligned.

The leaf spring 7 is between the blocking element 6 and the inner wall of the handle 11 arranged.

The string 8th is with one end on the axle 3 and with the other end attached to the crown (not shown). The hook head 9 is with a through hole 91 provided by the cord 8th is guided to limit the cord.

When the umbrella fabric is tensioned, the hook head becomes 9 in the upper area of the floor 12 drawn. After that, the stick can 12 be pressed to push the stick together. How out 3 it can be seen, the cord is 8th when pushing together the stick 12 through the elevator spring 5 on the axis 3 rolled up. When the pressure on the stick 12 disappears, turning back the axle 3 prevents the free end 61 of the blocking element 6 through the leaf spring 7 in the teeth 41 the ratchet 4 engages, leaving the crown of the cord 8th is held. This will eie rebound of the stick 12 prevented by the Aufspannfeder (not shown), so that when pushing the stick injury can be avoided.

If the stick 12 reached the folded state of the umbrella, as in 4 is shown, the hook head occurs 9 in the handle 11 and is controlled by the controller (not shown). The hook head pushes 9 the lead 62 and thus the blocking element 6 outward, creating the free end 61 of the blocking element 6 the teeth 41 the ratchet 4 leaves, leaving the teeth 41 the ratchet 4 from the blocking element 6 be released. When the umbrella is stretched, the cord can 8th be pulled because the ratchet 4 can be rotated as it is in 5 is shown.

Through the hook head 9 will lock the ratchet 4 through the blocking element 6 lifted, causing the ratchet 4 can be released and turned, leaving the cord 8th can be pulled. Therefore, the umbrella can be opened. It is also possible to use another control, the locking of the ratchet 4 through the blocking element 6 repealed.
