Abstract

When a conventional automatic umbrella is opened, the straight telescopic rod is just in the middle of the umbrella. Because the position of the telescopic rod is unfavorable when the umbrella is opened, only about one third of the area of the umbrella is effectively utilized. The aim of the invention is to increase the utilization of the surface. The umbrella of the invention consists of a curved telescopic rod (1) with a connecting piece (3), an umbrella cap head (2), an umbrella top rod system with an umbrella top surface (4), a slide block unit (5) and a handle (6). Due to the action of the connecting piece (3), the slider unit (5) and the deflectable umbrella cap head (2), the curved telescopic rod (1) is at the side of the opened umbrella and avoids the middle of the umbrella. The stabilization of the umbrella stem system, which opens together with the umbrella top (4), is achieved by the synergistic effect of the connecting piece (3), the guide slider (1.3), the umbrella cap (2), the slider unit (5), the strut rod (4.2) and the auxiliary strut rod (4.3).

The best embodiment of the invention.

Umbrella of the present invention consists of the following parts: a curved telescopic rod with a connector connecting the umbrella cap head, an umbrella top rod system fixed on the umbrella cap head with an umbrella top surface, a A slider unit consisting of a main slider and an auxiliary slider with compression springs, a guide slider that can be moved on the telescopic rod and a handle that is also mounted on the telescopic rod.

Through the synergy of the connecting piece, the slider unit and the deflectable canopy head, the curved telescopic rod is on the side of the opened umbrella and out of the way in the middle of the umbrella. The stability of the umbrella pole system that opens together with the umbrella top surface is ensured by the cooperation of the connecting piece, the guide unit, the umbrella head, the slider unit and the support and auxiliary poles that are swingably mounted on the slider unit .

When opening and retracting the umbrella, the slider unit that manipulates the umbrella ejector system is guided by the guide slider next to the telescopic rod.

The advantage of the present invention is that this new type of umbrella has a curved telescoping rod instead of a straight telescoping rod so that when the parachute is opened the telescopic rod is at the edge of the umbrella instead of being in the middle of the umbrella when the parachute is opened like a straight telescopic rod. Thus, the entire area of the opened canopy can be fully utilized without restriction.

In order to simplify the production of automatic umbrellas with curved telescopic poles, another embodiment of the invention is proposed, the slider unit of which can be slidably mounted on the telescopic poles like conventional automatic umbrellas, instead of being arranged near the curved telescopic poles . to this end. Changed the umbrella top pole system.

Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. In the attached picture:

Figure 1 is an automatic umbrella with a curved telescopic pole and a slider unit guided beside the telescopic pole.

Figure 2 is the upper part of the umbrella in Figure 1 .

Fig. 3 is a front view of Fig. 1 .

Figure 4 is the handle of an umbrella with the slider unit guided next to the telescoping pole.

Fig. 5 is the umbrella when the slider unit is installed on the telescopic rod,

Fig. 6 is the upper part of the umbrella in Fig. 5 .

The umbrella with the curved telescopic rod 1 shown in Fig. 1 contains the guide slider 1.3 that can be shiftably installed on the telescopic rod 1, and it guides the slider unit 5 beside the telescopic rod; Connector 3, its shape bends to different directions of telescopic rod 1, and is connected with umbrella top rod system and umbrella top surface 4 through umbrella cap head 2; It also contains a handle 6 installed on the lower part of the curved telescopic rod.

The umbrella ejector system composed of the umbrella top bar 4.1 and the support and auxiliary support bars 4.2 and 4.3 is connected to the slider unit 5 through the support and auxiliary support bars 4.2 and 4.3.

The telescopic rod 1 can consist of two or three curved rods. The rods of the telescopic rod 1 are rotatably guided and locked against each other in their extended position by the locking mechanism 1.1. These rods are pressed out of each other by means of compression springs 1.2.

As shown in Figure 2, the connecting piece 3 is at the upper end of the curved telescopic rod 1, and the umbrella head 2 is installed on the connecting piece 3, and can only deflect in a limited angle in one direction. Here, the umbrella head 2 The deflection axis is higher than the horizontal plane E1 where the connection point between the umbrella top rod 4.1 and the umbrella cap head 2 is located. Furthermore, the connecting part 3 has a connecting rod 3.1 to which the slider 5 is fastened when the umbrella is opened, and an adapter part 3.2 parallel to the connecting rod 3.1.

It can also be seen in FIG. 2 that the guide slide 1.3, which is displaceably mounted on the telescopic rod 1, is connected to the auxiliary slide 5.1 of the slide unit 5 by means of a ring so that it can only pivot in one plane. The guide slide 1.3 can be one-piece or two-part, in the two-part embodiment shown here, the two parts are butted and connected together in a deflectable manner.

The slider unit 5 is a closed unit consisting of the main slider 5.2, the auxiliary slider 5.1 and the compression spring 5.3. Here, the auxiliary slider 5.1 can only be deflected in one plane with the Guide slider 1.3 connection. The auxiliary slider forms a guide groove 5.5 of a connecting rod 3.1 with two flared prongs 5.5 (FIG. 3) and enables a secure rotational connection of the slider unit 5 to the connecting rod 3.1 of the connecting part 3. The auxiliary slide block 5.1 also has a guide rod 5.4 on which a compression spring 5.3 and a main slide block 5.2 are movably installed.

The support pole 5.3 and the auxiliary pole 4.3 of the umbrella top pole system 4.2 are deflectably installed on the surfaces of the auxiliary slider 5.1 and the main slider 5.2. At the other end, the support pole 4.2 is hingedly connected with the umbrella top pole 4.1, and the auxiliary pole 4.3 is respectively hinged with the support pole 4.2.

In Fig. 3, at the slider unit 5, next to the two flared prongs 5.5 forming the guide groove of the connecting rod 3.1, the guide rod 5.4 is shown with two laterally arranged recesses 5.4.1 at the lower end. They are adapted to the locking mechanism in the handle 6 .

The handle 6 shown in FIG. 4 has a downwardly pointed guide groove C for the slider 5.4 of the slider unit 5, in which the locking mechanism is mounted. The locking mechanism consists of a release key 6.1 and a tension spring 6.2. In the retracted state of the umbrella, the tension spring engages in the recess 5.4.1 of the guide rod 5.4, thereby fixing the slider unit.

To open the umbrella, press the release button 6.1. The tension spring 6.2 of the locking mechanism is thus ejected from the recess 5.4.1 of the guide rod 5.4. The slider unit 5 released in this way pops up in the direction of the umbrella head until the telescopic rod reaches a certain plane, which is connected by the deflection of the guide slider 1.3 and the auxiliary slider 5.1 of the slider unit and the umbrella head 2 and the connecting piece 3 deflection connection OK. At the same time the rods of the bent telescopic rods 1 are pulled outwards from each other.

When reaching the connecting piece 3, the slider unit 5 opens the umbrella top rod system and the umbrella top surface 4, and is attached to the connecting rod 3.1 of the connecting piece 3, wherein the connecting rod 3.1 slides in the guide groove of the auxiliary slider 5.1. Here, the pointed head 5.5 of the auxiliary slider 5.1 ensures accurate connection of the slider unit 5 and the connecting piece 3 .

The structure of the connecting piece 3 limits the deflection angle of the umbrella head 2, and enables the slider unit 5 to be attached to the connecting rod 3.1 of the connecting piece 3, so that the upper part of the umbrella constitutes a stiff unit in the opened state. As a result, the umbrella pole system remains stable and withstands the umbrella roof 4 despite wind pressure.

In the embodiment where the guide slider 1.3 is separated as shown in Fig. 2, the wind force is not only borne by the slider unit 5 and the support rod 4.2 of the connecting rod 3.1, but also by the connecting support rod 4.2, the auxiliary slider 5.1, the guide slider The block 1.3 and the joint 3.2 of the link 3 parallel to the connecting rod 3.1 are transferred to the telescopic rod 1 . When the wind pressure rises, the connecting piece 3.2 of the connecting piece 3 also prevents the sliding block 5 from decoupling from the connecting rod 3.1 by itself.

When retracting the umbrella, pull down the main slider 5.2 in the direction of the handle 6. Here, through the cooperative action of the supporting pole 4.2 and the auxiliary pole 4.3, the umbrella top pole system and the umbrella top surface 4 are evenly folded around the curved telescopic pole 1 together. The slider unit 5 is decoupled from the connecting rod 3.1, slides and gathers, and compresses the compression spring 5.3 together. During this process, the lower end of the guide rod 5.4 of the auxiliary slider 5.1 protrudes about 2 centimeters from the main slider 5.2.

When the main slider is pulled down again, the slider unit 5 and the guide slider 1.3 slide together along the telescopic rod 1 toward the handle 6, so that the guide slider 1.3 is pressed against the stop device 1.1. Thus each rod of the telescopic rod 1 is released from the firm connection, and these rods are retracted alternately again. At this moment, the compression spring 1.2 is compressed.

To end the retraction process, push the lower end of the guide rod 5.4 into the guide groove C of the handle 6 until the tension spring of the locking mechanism springs into the recess 5.4.1. The process of closing the umbrella is over.

In order to simplify the production of automatic umbrellas with curved telescopic poles 1 , FIGS. 5 and 6 present another embodiment of the invention. At this moment, its slider unit 5 can be slidably arranged on the telescopic rod like a conventional automatic umbrella, rather than being arranged beside the curved telescopic rod. For this purpose, the umbrella pole system was changed.

As mentioned above, the umbrella shown in FIG. 5 mainly consists of the following parts: a curved telescopic rod 1, an umbrella top rod 4.1 with an umbrella top surface 4, a slider unit 5 and a handle 6. Here the telescopic rod 1 can be made up of two or three curved rods.

The rods of the telescopic rod 1 are rotatably guided and locked against each other in their extended position by the locking device 1.1. These rods are pulled out of each other by means of compression springs 1.2.

The connecting piece 3 is located at the upper end of the curved telescopic rod 1, and it has a shape of a turning point different from the direction of the telescopic rod 1. The umbrella head 2 is installed on the connecting piece 3, and can only deflect in a limited angle in one direction. Here, the deflection axis of the umbrella head 2 is higher than the horizontal plane where the umbrella top rod 4.1 and the umbrella head 2 are connected. E1.

The slider unit 5 is slidably installed on the telescopic rod 1 and consists of a main slider 5.2, an auxiliary slider 5.1 and a compression spring 5.3.

The supporting struts 4.2 that create the hinged connection between the auxiliary slider 5.1 and the umbrella top pole 4.1 are different from the embodiments described in FIGS. be installed on the umbrella top pole 4.1 with different distances.

In order to ensure the function of the slider unit 5, a plurality of units of additional struts 4.4 and 4.5 that can be deflected to each other are arranged on the umbrella top rod 4.1 and the auxiliary slider 5.1, that is, on the opened umbrella, the additional struts 4.5 and 4.5 The included angle β of the auxiliary slider 5.1 is the same as the included angle between the supporting rod 4.2 on the opposite side and the auxiliary slider 5.1.

With the help of the angle β between the additional support rod 4.5 and the auxiliary slider 5.1 and the support rod 4.2 on the opposite side and the auxiliary slider 5.1, when the umbrella is opened, the compression spring 5.3 acts on the auxiliary slider 5.1 evenly , so as to prevent the slider unit from being stuck on the telescopic rod 1.

In addition, the end of the additional strut 4.5 facing away from the auxiliary slider 5.1 is bent upwards. Therefore, the connection axis with the additional strut 4.4 cannot form a sharp ridge.

The additional strut 4.5 and the support strut 4.2 on the opposite side are hingedly connected with the main slider 5.2 by means of the auxiliary strut 4.3.

The handle 6 installed at the lower end of the telescopic rod 1 is ergonomically shaped such that the opened umbrella will automatically be guided to the correct position in a comfortable grip.

When the parachute is to be opened, the release key 6.1 in the handle 6 is pressed. In this way, the released slider unit 5 pops up on the telescopic rod 1 toward the umbrella head. At the same time the rods of the bent telescopic rods 1 are pulled outwards from each other. When reaching the connecting piece 3, the slider unit 5 opens the umbrella pole system and the umbrella top surface 4.

When the umbrella is to be retracted, the main slide block 5.2 is pulled down. At this time, through the cooperative action of the support pole 4.2 and the auxiliary pole 4.3, the umbrella top pole system and the umbrella top surface 4 are evenly folded around the curved telescopic pole 1 together. The slider unit 5 slides and gathers, and compresses the compression spring 5.3.

When the main slide block 5.2 was pressed onto the stopper 1.1, each rod of the telescopic rod 1 released the firm connection, and these rods were alternately adducted again. At this moment the compression spring 1.2 is compressed. When the main slider 5.2 reaches the handle 6, the locking mechanism is released, thus ending the process of closing the umbrella.
