Description

genus

The invention relates to a multiply folded, fully automatically opening and closing screen.

State of the art

In recent years, the instability of the weather has made it common for everyone to have an umbrella with them, to prevent them from getting wet through a downpour of rain. However, with the first umbrellas, the umbrella frame had to go up with the hand be pushed in a certain position so that the umbrella could be stretched. In the event of a sudden rain shower, it was often not possible to open the umbrella in time and became wet. Therefore, umbrellas were constructed in which the umbrella handle was provided with a button. By pressing this button, the umbrella could be automatically tensioned. But an automatic closing function was not available, so if you wanted to get into a vehicle, you still had to use both hands at the same time to fold the screen and then get in, and you were still slightly wet during this short interval. In this way, the comfort of the umbrella was lost.

The typical internal structure of an automatically foldable and collapsible screen can be found, for example, in the Chinese utility model number CN2476208Y, for the 13.02.2002 the utility model protection was granted. In this utility model, a control device for an automatically foldable and collapsible umbrella has been disclosed. This automatically foldable and foldable umbrella has the following operating principle: when you open the umbrella presses a button, which releases the control device of the stick and releases a tension spring inside the pole energy and through which the stick is stretched upward and the screen is stretched. When folding the screen, the button is pressed again, whereby the Regelvor-direction of an in-store buckle is also solved. If the Buckle is released, is folded by action of the spring force of the tension spring on the umbrella frame of Schirmstoff, and the buckle is pulled by a pull rope back into the upper part of the stick. The screen is not yet completely closed. To fully close the shield, the screen cloth must be pushed with force towards the grip so that the stick is collapsed and the tension spring re-stores energy until the stick and buckle are again held by the regulator in the umbrella grip. Only then is the umbrella folded back completely.

The existing automatically foldable and collapsible screens work in principle similar to the utility model described above. Among the Chinese utility model applications 01217730.X, 01237609.4, 01262761.5 and 03267824.X u.a. such umbrellas became known. They differ mainly by the mounted inside the umbrella handles control devices for stick and buckle.

From this it can be seen that the existing automatically foldable and collapsible screens actually only open automatically and can be semi-automatically closed. However, it is not possible to fully automatically fold these screens down to their original state before opening the screen. It is necessary to apply force twice to completely close the screen. Completely open a screen by means of a rule handle and fully closed Close was the problem to be solved by this invention. This resulted in the following solution.

The CN 101 961 164 A discloses a multiply folded, fully automatically opening and closing screen, comprising: a umbrella frame with a closing spring, a screen fabric attached to the Schirmstoff, a pole unit, a screen attached to the upper end of the canopy, a screen attached to the pole unit screen and a shield handle; wherein the umbrella frame, the screen crown and the screen slider are matched, the screen having a translation mechanism for opening and closing the screen in the pole unit and a drive mechanism for opening and closing the screen incorporated in the umbrella grip and the pole unit is, wherein the stock unit consists of at least three tubes: from top to bottom outer tube, center tube and inner tube; an outer tube roll being located at the upper end of the outer tube, a central tube stopper having a center tube roll attached to the upper end of the central tube, and a middle tube retaining ring at the lower end and the lower end of the inner tube secured to the umbrella handle, the translation mechanism for opening and closing the umbrella consists of a Schieberzugseil, a Mittelrohrzugseil and a Innerohrzugseil, one end of the Schieberzugseils is attached to the central tube plug, and the other end passes through the outer tube and around the outer tube roll around the screen slide on which it is fixed, wherein the one end of the Mittelrohrzugseils is attached to the upper end of the inner tube, wherein the end of Innenrohrzugseils is attached to the upper end of the inner tube, wherein the drive mechanism for opening and closing the screen consists of drive parts, and a drive unit, which driving the drive parts corresponding up and down movement of the inner tube, wherein the drive unit is controlled by a button on the umbrella handle.

When using the described solution, the screen according to the invention operates as follows:

• When the screen is opened, pressing the button on the umbrella handle triggers the delivery of motive power by the drive unit. The drive unit drives the drive parts, whereby the inner tube moves upwards accordingly. At the same time, the center pipe plug connected thereto is extended in accordance with the upward movement of the center pipe, the distance between the center pipe plug and the upper end of the center pipe increases, and the inner pipe pull rope pulls the outer pipe holding ring which moves upward corresponding to the center pipe to compensate for the change of that distance. As a result, the outer tube is set in motion at the same time, which extends according to the central tube, wherein the distance between the outer tube plug and center tube plug increased. The pusher pull rope in turn pulls the pusher which moves in accordance with the upward movement of the outer tube to compensate for the change in that distance. The upward movement of the slider opens the umbrella frame. Through this sequence of synchronous movements, the complete opening of the screen is achieved.

When closing the screen, the drive unit is started again by pressing the button on the umbrella handle. The drive unit drives the drive parts, causing the inner tube moves down accordingly. At the same time, the inner tube is moved downwardly and contracted by the action of the downward movement of the center tube plug connected to the drive parts to the center tube. At the same time, the slider pull rope connected to the center tube plug pulls the slider which moves upwardly with the outer tube accordingly. Due to the effect of the closing spring and the Schirmstoffes the umbrella frame is folded.

The pole unit B has three tubes, in order from top to bottom, it is an outer tube B1, a center tube B2 and an inner tube B3.

In the outer tube B1, an outer tube plug 1 is fixed at the upper end inside, at the lower end of the outer tube, a Außenrohrhaltering 2 is attached. The outer tube plug 1 has in the middle of a through hole 11, at the same time located at the upper part of the outer tube plug 1, an outer tube roller 12; the outer tube B1 forms at the point where the outer tube roller 12 is located, a notch B11 through which the Schieberzugseil mentioned E1 runs. at the outer tube retaining ring 2 is an annular body whose upper end is fixed in the outer tube B1 and whose lower end is designed as a flange 21 which protrudes from the outer tube B1.

At the upper end of the center pipe B2, a center pipe plug 3 is fixed, at the lower end of the center pipe, a center pipe holding ring 4 is fixed, the lower end of the center pipe plug 3 is fixed in the center pipe B2, and it is provided with a central pipe roll 31 in the middle. Of this central tube roller 31, one or more may be present; The example version is provided with two rollers. The center tube retaining ring 4 is also an annular body whose upper end is fixed in the central tube B2, and whose lower end is designed as a flange 41 which protrudes from the central tube. In addition, one side of the flange 41 is provided with the center tube holding ring roller 42. At the location of the central tube B2, at which the central tube holding ring roller 42 is located, it forms a notch, through which the middle tube pull rope E2 mentioned below runs.

At the upper end of the inner tube B3, an inner tube plug 5 is fixed, the lower end of the inner tube B3 is attached to the umbrella grip G.

The connections between the three tubes are defined by the respective plugs, for example the central tube plug 3 and the inner tube plug 5, and the retaining rings of the respectively adjacent tube parts, for example the outer tube retaining ring 2 and the center pipe holding ring 4 is formed. Together they form the stick unit B, whose parts unfold and fold together. It is not necessary to additionally provide them with a connection limit.

The crown C is attached to the tip of the outer tube B1. Its lower part is located on the outer tube B1 and forms a cap groove C1, which fits on the notch B11 of the outer tube B1. Through these runs the mentioned below Schieberzugseil E1.

The slider D is slidably mounted on the outer tube B1.

The translation mechanism E for the opening and closing of the screen consists of a Schieberzugseil E1, a Mittelrohrzugseil E2 and a Innenrohrzugseil E3.

In this case, one end of the Schieberzugseils E1 is attached to the upper end of the central tube plug 3, the other end passes through the outer tube B1 and around the outer tube roller 12 of the outer tube plug 1 around the slide D to which it is attached.

One end of the middle tube pull rope E2 is fixed to the upper end of the inner tube B1, this point is fixed to the inner tube plug 5. The other end passes through the notch B21 in the bottom of the center pipe B2 and around the center pipe holding ring roller 42 of the center pipe holding ring 4 into the center pipe B2, through the top end the center tube B2 back out and into the outer tube B1 and then through the upper end of the outer tube B1 back out to the outer tube plug 1 to which it is attached.

The one end of the Innenrohrzugseils E3 is attached to the upper end of the inner tube B3, this point is in turn attached to the inner tube plug 5. The other end passes through the center pipe B2 and around the roller 32 of the center pipe plug 3 and thereafter into the space between the center pipe B2 and the outer pipe B1 where it is fixed to the lower end of the outer pipe B1. This point is attached to the flange 21 of the outer tube retaining ring 2.

Since both one end of the middle tube pull rope E2 and one end of the inner tube pull rope E3 are fixed to the upper end of the inner tube, the center tube pull rope E2 and the inner tube pull rope E3 can use the same connection rope, knotting only at the rope to make it at the upper end of the rope Inner tube to attach.

The drive mechanism F for opening and closing the screen consists of a drive tube 6, a nut 7, a threaded spindle 8 and a drive unit 9, which moves the drive tube 6. The drive unit 9 is a motor 91 with gear 92, which is connected to the drive tube 6. Alternatively, a mechanical drive with change gear can be used be who drives the drive tube 6. Of course, the shaft of the motor can be coupled directly to the drive tube 6. The drive tube 6 is inserted in the inner tube B1, its length is matched to the inner tube B1. The nut 7 is fixed inside at the upper end of the drive tube 6, the threaded spindle 8 is mounted in the nut 7. By the forward and backward rotation of the nut 7, the threaded spindle 8 is driven, which moves according to the nut 7 up and down. The upper end of the threaded spindle 8 is fixed to the central tube plug 3.

In the umbrella handle G is a cap in which the drive unit 9 is mounted. Its upper part is attached to the cap lid G1. In the middle of Kappendeckeis G1 is a through hole G11, so that the drive tube 6 and the shaft 93 of the drive unit 9 can be connected to each other. The inner tube B3 of the stock unit B is attached to the cap lid G1, in addition to the cap of the umbrella grip G, a knob G2 is mounted, with the forward rotation and the reverse rotation of the drive unit 9 are actuated.

How out Fig. 5 . 5a and 5b it can be seen, with normal closing of the automatic umbrella first the individual tubes of the pole unit B are contracted, the threaded spindle 8 is fully retracted into the drive tube 6, and the slider D is located at the lower end of the outer tube B.

How out Fig. 4 . 4a and 4b it can be seen, the button G2 is pressed on the umbrella handle G when opening the screen and so the forward running of the drive unit 9 triggered. The drive unit 9 moves the drive tube 6, the drive tube 6 moves the nut 7, whereby the nut 7 pushes the threaded spindle 8, so that correspondingly the inner tube B3 moves upwards. At the same time, the center pipe B2 is pushed and correspondingly the inner pipe B3 is stretched upward. With the upward movement of the center tube, the distance between the center tube plug 3 and the upper end of the center tube B3 increases, and the inner tube pull rope E3 pulls the outer tube holding ring 2, which moves upwardly corresponding to the center tube B2 to compensate for the change of this distance. As a result, the outer tube B1 is extended at the same time corresponding to the central tube, whereby the distance between outer tube plug 1 and central tube plug 3 increases. The slider pull rope E1, in turn, pulls the slider D which moves upward in accordance with the upward movement of the outer tube B1 to compensate for the change in this distance. The upward movement of the slider D opens the umbrella frame A. Through this sequence of synchronous movements, the complete opening of the umbrella is achieved. It should be noted that when you open the screen, the Innenrohrzugseil E3 and the Schieberzugseil E1 mainly serve to trigger the clamping movement of the screen, while the Mittelrohrzugseil E2 only serves to ensure that in reducing the distance between Mittelrohrhaltering 4 and the upper end of the inner tube B3 at the same time the distance between the outer tube plug 1 and the upper end of the inner tube B3 changes as it becomes larger.

How out Fig. 5 . 5a and 5b it can be seen, when the screen is closed, the button G2 is pressed again on the umbrella handle G and thus the reverse running of the drive unit 9 is triggered. The drive unit 9 moves the drive tube 6 in the opposite direction, the drive tube 6 moves the nut 7, whereby the nut 7 pulls the threaded spindle 8, so that correspondingly moves the inner tube B3 down. At the same time, by the action of the downward movement of the center pipe plug 3 connected to the threaded spindle 8, the center pipe B2 is moved downward, and with the center pipe B2, the inner pipe B3, which is contracted. Simultaneously, the slider pull rope E1 connected to the center tube plug 3 pulls the slider D, which moves upward with the outer tube B1. By the action of the closing spring A1 and the Schirmstoffes the umbrella frame A is folded. At this time, the distance between the center tube holding ring 4 and the upper end of the inner tube B3 increases, and the middle tube pulling rope E2 pulls the outer tube plug 1, which drives the outer tube B1 and accordingly moves the center tube B2 downward and contracts. Through this sequence of synchronous movements closing the screen is achieved. It should be noted that when closing the screen, the middle tube pull rope E2 and the slider pull rope E1 mainly serve to trigger the closing movement of the umbrella, while the inner tube pull rope E3 serves only to make sure that, as the distance between the outer tube retaining ring 2 and the center tube plug 3 increases, the distance between the center tube plug 3 and the upper end of the inner tube B3 simultaneously becomes smaller.

Of course, the drive mechanism F for opening and closing the screen is not limited to the structure described above. Once a prime mover 9 can drive the up and down movement of a corresponding inner tube B3 and thereby move an associated center tube plug, it is possible to achieve that the drive causes both opening and closing of the shield.

Summarizing the construction described above, by the translation mechanism E located in the floor unit B of the screen in combination with the connection between slider cable E1, middle tube cable E2 and inner tube cable E3 of the transmission mechanism E, the individual tubes of the floor unit B and screen crown C and screen slide D, and in conjunction with the drive mechanism F located in the umbrella handle G for opening and closing the umbrella, which also moves the inner tube B3 in parallel with the up and down movement of the center tube B2 of the pole unit B, in this invention achieves that the individual At the same time, open and close the pipe sections of the unit B and the screen cloth. In this way, in the folded-folded automatic Umbrella fully automatic opening and closing achieved, so that the screen is particularly convenient and quick to handle.
