Abstract
In a conventional automatic umbrella, the straight telescopic shaft is located exactly in the middle of the umbrella when opened. Due to the unfavorable position of the telescopic shaft, only approximately 1/3 of the umbrella area is used. The aim of the invention is to increase the utilization ratio of the umbrella area. The inventive umbrella is comprised of a curved telescopic shaft (1) with a connecting piece (3), of the crown (2), the top rod system with the top cover (4), the slid unit (5), and of the handle (6). The connecting piece (3), the slide unit (5) and the pivotal crown (2) enable the curved telescopic shaft (1) to be laterally situated in relation to the opened top cover (4), and keeps the middle of the umbrella free. The stability of the opened top rod system with the top cover (4) is guaranteed by the interaction of the connecting piece (3), the guide slide (1.3), the crown (2), the slide unit (5), the support braces (4.2) and of the auxiliary braces (4.3).
Description
AUTOMATIC UMBRELLA WITH CURVED TELESCOPIC SHAFT
A conventional automatic umbrella includes essentially the following components: a straight telescopic shaft to which ends are mounted a crown and a grip with the closure mechanisms, a main and auxiliary slide member and a top cover, which is supported by a top rod system, which in turn consists of a plurality of support rods and auxiliary rods which are pivotally connected with the crown, the main and the auxiliary slide member (DE 35 319 51 A1).
Upon closing of the umbrella, the sections of the telescopic shaft are pushed one into another, the top cover with the top rod system is folded together about the shortened telescopic shaft and the load springs which are found in the telescopic shaft and between the main and auxiliary slide members are tensioned. Upon opening of the umbrella, the spring forces open the top rod system with the top cover; the sections of the telescopic shaft also extend.
The telescopic shaft is located in the middle of the open umbrella. Only one third of the umbrella surface is effectively used when the umbrella is open because of the unfavourable position of the telescopic shaft. It is an object of the invention to increase the proportion of the useable area.
This object is achieved with the features listed in claims l and 7. Preferred embodiments of the invention result from the dependent claims.
The umbrella in accordance with the invention includes a curved telescopic shaft with a connecting member to the crown, a top rod system with top cover mounted to the crown. A slide unit made of a main slide member and an auxiliary slide member with an intermediately positioned compression spring, a guide member slidable on the telescopic shaft and a grip also mounted to the telescopic shaft.
Through cooperation of the connecting member, the slide unit and the pivotable crown, the curved telescopic shaft is positioned laterally relative to the opened top cover and leaves the centre of the umbrella free. The stability of the opened top rod system with top cover is ensured through the cooperation of the connecting member, the guide member, the crown, the slide unit and the support and auxiliary rods pivotally connected to the slide unit.
During opening and closing of the umbrella, the slide unit which operates the top rod system is guided beside the telescopic shaft by way of the guide member.
The advantages achieved with the invention consist in that the new umbrella instead of having a straight telescopic shaft in the middle of the opened umbrella has a curved telescopic shaft which is thereby positioned at the rim of the opened umbrella.
This makes the whole surface of the opened top cover available without restriction.
In order to simplify the manufacture of the automatic umbrella with curved telescopic shaft, it is suggested in an altered embodiment in accordance with the invention to slidably mound the slide unit on the telescopic shaft as in conventional automatic umbrellas, instead of beside the curved telescopic shaft. This requires changes in the top rod system.
Embodiments of the invention are illustrated in the drawings and are further described in the following.

The umbrella in accordance with the invention includes a curved telescopic shaft with a connecting member to the crown, a top rod system with top cover mounted to the crown. A slide unit made of a main slide member and an auxiliary slide member with an intermediately positioned compression spring, a guide member slidable on the telescopic shaft and a grip also mounted to the telescopic shaft.

This makes the whole surface of the opened top cover available without restriction.
In order to simplify the manufacture of the automatic umbrella with curved telescopic shaft, it is suggested in an altered embodiment in accordance with the invention to slidably mound the slide unit on the telescopic shaft as in conventional automatic umbrellas, instead of beside the curved telescopic shaft. This requires changes in the top rod system.
Embodiments of the invention are illustrated in the drawings and are further described in the following.
Figure 1 shows an automatic umbrella with curved telescopic shaft and a slide unit guided beside the telescopic shaft;
Figure 2 shows the upper part of the umbrella shown in Figure 1;
Figure 3 illustrates the portion A shown in Figure 1;
Figure 4 shows the grip of the umbrella when the slide unit is guided beside the telescopic shaft;
Figure 5 shows the umbrella with the slide unit positioned on the telescopic shaft;
and Figure 6 shows the upper part of the umbrella shown in Figure 5.
The automatic umbrella With curved telescopic shaft 1 illustrated in Figure 1 includes a guide member 1.3 slidably mounted on the telescopic shaft 1, which guides a slide unit 5 beside the telescopic shaft 1, a connecting member 3 located at the top of the curved telescopic shaft 1, which includes a shape curved in the opposite direction of the telescopic shaft 1 and which is connected with the top rod system and the top cover 4 by way of a crown 2, and a grip 6 located at a bottom end of telescopic shaft 1.
The top rod system, including the top rods 4.1 and the support and auxiliary rods 4.2 and 4.3 is connected with the slide unit 5 by way of the support and auxiliary rods 4.2 and 4.3.
The telescopic shaft 1 can consist of two or three curved rods. The rods of the telescopic shaft 1 are guided in one another against relative rotation and are secured to one another in their extended position by stops 1.1. The rods are extended with the help of load springs 1.2.
As shown in Figure 2, the connecting member 3 is located at the upper end of the curved telescopic shaft 1. The crown 2 is pivotally mounted on the connecting member 3 for movement in only one direction and over a limited angle, whereby the pivot axis of the crown 2 is located higher than the plane E1 in which the points of connection between the top rods 4.1 and the crown 2 are located. Furthermore, the connecting member 3 includes a connecting pin 3.1 against which the slide unit S rests when the umbrella is opened, and an intermediate member 3.2 extending parallel to the connecting pin 3.1.
Figure 2 illustrates further that the guide member 1.3 slidably mounted on the telescopic shaft is slidably connected with the auxiliary slide member 5.1 of the slide unit S by way of an eyelet and for movement in only one plane. The guide member 1.3 can be unitary or made of two parts, whereby in the illustrated two-part embodiment the parts are positioned buffet to buffet and are pivotally connected with one another.
The slide unit 5 is a closed unit and consists of the main slide member 5.2, the auxiliary slide member 5.1 and the compression spring 5.3, whereby the auxiliary slide member 5.1 is pivotally connected with the guide member 1.3 for movement in only one plane by way of an eyelet positioned thereon. The auxiliary slide member 5.1 with two spread apart tongues 5.5 (Figure 3) forms a guide channel for the connecting pin 3.1 and thereby guarantees a non-rotatable connection of the slide unit S with the connecting pin 3.1 of the connecting member 3. The auxiliary slide member 5.1 further has a guide pin 5.4 on which the compression spring 5.3 and the main slide unit 5.2 are moveably positioned.
The support rods 4.2 and the auxiliary rods 4.3 of the top rod system are pivotally connected to the flanges of the auxiliary slide member 5.1 and the main slide member 5.2. At their respective other end, the support rods 4.2 are jointed to the top rods 4.1 and the auxiliary rods 4.3 are jointed to the support rods 4.2.
Figure 3 shows that the slide unit 5 apart from the two spread apart tongues 5.5 which form a guide channel for the connecting pin 3.1 includes a guide pin 5.4 which at a lower end has two laterally positioned constrictions 5.4.1. They cooperate with the closure mechanism in grip 6.
The grip 6 illustrated in Figure 4 includes a guide channel C for the lower tip of the guide pin 5.4 of the slide unit S and the closure mechanism is positioned therein.
The closure mechanism consists of a trigger button 6. l and a spreader spring 6.2 which in the closed condition of the umbrella engages the constrictions 5.4.1 of the guide pin 5.4 and thereby locks the slide unit.
When the umbrella is to be opened, the trigger button 6.1 is pushed. The spreader spring 6.2 of the closure mechanism thereby jumps out of the constrictions 5.4.1 of the guide pin 5.4. The thereby freed slide unit 5 advances in direction of the crown 2 along the telescopic shaft onto a preselected plane which is defined by the pivotal connection of the guide member 1.3 with the auxiliary slide member 5.1 of the slide unit 5 and a pivotal connection of the crown 2 with the connecting member 3.
Simultaneously, the rods of the curved telescopic shaft 1 are extended.
The slide unit 5 upon reaching the connecting member 3 opens the top rod system with the top cover 4 and rests against the connecting pin 3.1 of the connecting member 3 in that the connecting pin 3.1 slides into the guide channel of the auxiliary slide member 5.1. The tongues 5.5 of the auxiliary slide member 5.1 thereby guarantee an exact connection of the slide unit 5 with the connecting member 3.
Because of the construction of the connecting member 3, which limits the pivot angle of the crown 2 and enables the locking of the slide unit 5 on the connecting pin 3.1 of the connecting member 3, the upper part of the umbrella forms a rigid unit in the opened condition. The top rod system thereby remains stable despite the wind pressure and carries the top cover 4.
In the embodiment illustrated in Figure 2 with the split guide member 1.3, the wind force is transferred to the telescopic shaft not only through the support rods 4.2 of the slide unit 5 and the connecting pin 3.1, but also through the connection of support rods 4.2, auxiliary slide member 5.1, and guide member 1.3, and through the intermediate part 3.2 of the connecting member 3 parallel to the connecting pin 3.1. The intermediate member 3.2 of the connecting member 3 also prevents the independent unhooking of the slide unit 5 from the connecting pin 3.1 under increased wind pressure.
In order to close the umbrella, the main slide member 5.2 is pulled downwards in direction to the grip 6. The top rod system with the top cover 4 is thereby evenly folded about the curved telescopic shaft through cooperation of the support rods 4.2 and the auxiliary rods 4.3. The slide unit 5 unhooks from the connecting pin 3.1, slides together and tensions the compression spring 5.3. The lower end of the guide pins 5.4 of the auxiliary slide member 5.1 thereby slides out of the main slide member 5.2 by about 2 cm.
Upon further downward pulling of the main slide member 5.2, the slide unit S
is guided by way of the guide member 1.3 along the telescopic shaft 1 in direction of the grip 6, whereby the guide member 1.3 pushes on the latches 1.1. The stable connection of the rods of the telescopic shaft is thereby loosened and the rods are pushed into one another. The compression springs 1.2 are thereby pressed together.
At the end of the closing operation, the lower end of the guide pin 5.4 is pushed into the guide channel C of the grip 6 until the spreader spring 6.2 of the closing mechanism advances into the constrictions 5.4.1. The closing operation is completed.
In order to simplify the manufacture of the automatic umbrella with curved telescopic shaft, a further embodiment is illustrated in Figures 5 and 6. In this case, the slide unit 5 is slidably positioned on the curved telescopic shaft 1 as in conventional automatic umbrellas instead of beside the curved telescopic shaft 1.
The umbrella illustrated in Figure S, like the one described further above, consists essentially of a curved telescopic shaft l, the top rods 4.1 with the top cover 4, the slide unit 5 and the grip 6. The telescopic shaft 1 can thereby consist of two or three curved rods.
The rods of the telescopic shaft are guided in one another against rotation and are secured in their extended position by latches 1.1. -The rods are extended with the help of compression springs 1.2.
The connecting member 3 which has a shape curved in a direction opposite the one of the curved telescopic shaft 1 is positioned at an upper end of the curved telescopic shaft 1. The crown 2 is pivotally mounted on the connecting member 3 for rotation through a limited angle and in one direction only, whereby the pivot axis of the crown 2 is located higher than the plane E1 in which the connecting points of the top rods 4.1 with the crown 2 are located.
The slide unit 5 is slidably mounted on the telescopic shaft l and consists of the main slide member 5.2, the auxiliary slide member 5. l and the compression spring 5.3.
In contrast to the embodiment described in Figures 1 to 4, the support rods 4.2, which form a jointed connection between the auxiliary slide member 5.1 and the top rods 4.1, are of different lengths and are mounted to the top rods 4.1 at varying distances from the crown 2.
In order to guarantee the function of the slide unit 5, several units of the mutually relatively pivotable additional rods 4.4 and 4.5 are mounted to the top rods 4.1 or the auxiliary slide member 5.1 in such a way that the additional rods 4.5 are oriented at the same angle (3 to the auxiliary slide member S.1 as the support rods 4.2 at the opposite side of the opened umbrella. In the opened umbrella, the compression spring 5.3 evenly acts on the auxiliary slide member 5.1 because of the angle [3 between the additional rods 4.5 and the auxiliary slide member 5.1 as well as the respectively opposing support rods 4.2 and the auxiliary slide member 5.1, which prevents jamming of the slide unit 5 on the telescopic shaft 1. Furthermore, the additional rods 4.5 are upwardly bent at the end away from the auxiliary slide member 5.1 so that the connection axis with the additional rods 4.4 does not form any sharp corners.
The additional rods 4.5 or the respectively opposite support rods 4.2 are jointedly connected with the main slide member 5.2.
The grip 6 mounted at the lower end of the telescopic shaft 1 is ergonomically shaped so that a single comfortable grip allows automatic correct positioning of the opened umbrella.
When the umbrella is to be opened, the trigger button 6.1 in the grip 6 is pressed. The thereby freed slide unit 5 jumps into direction of the crown 2 on the telescopic shaft 1. At the same time, the rods of the curved telescopic shaft are extended.
The slide unit 5 upon reaching the connecting member 3 opens the top rod system with the top cover 4.
In order to close the umbrella, the main slide member 5.2 is pulled down-wardly. Through the cooperation of the support rods 4.2 and the auxiliary rods 4.3, the top rod system with the top cover 4 is evenly folded about the curved telescopic shaft. The slide unit 5 is pushed together and tensions the compression spring 5.3.
When the main slide member 5.2 presses on the latch 1.1, the stable connection of the rods of the telescopic shaft 1 is loosened and the rods are pushed into one another. The compression springs 1.2 are thereby compressed. When the main slide member 5.2 reaches the grip 6, a closing mechanism is triggered and thereby the closing operation completed.

As shown in Figure 2, the connecting member 3 is located at the upper end of the curved telescopic shaft 1. The crown 2 is pivotally mounted on the connecting member 3 for movement in only one direction and over a limited angle, whereby the pivot axis of the crown 2 is located higher than the plane E1 in which the points of connection between the top rods 4.1 and the crown 2 are located. Furthermore, the connecting member 3 includes a connecting pin 3.1 against which the slide unit S rests when the umbrella is opened, and an intermediate member 3.2 extending parallel to the connecting pin 3.1.
Figure 2 illustrates further that the guide member 1.3 slidably mounted on the telescopic shaft is slidably connected with the auxiliary slide member 5.1 of the slide unit S by way of an eyelet and for movement in only one plane. The guide member 1.3 can be unitary or made of two parts, whereby in the illustrated two-part embodiment the parts are positioned buffet to buffet and are pivotally connected with one another.
The slide unit 5 is a closed unit and consists of the main slide member 5.2, the auxiliary slide member 5.1 and the compression spring 5.3, whereby the auxiliary slide member 5.1 is pivotally connected with the guide member 1.3 for movement in only one plane by way of an eyelet positioned thereon. The auxiliary slide member 5.1 with two spread apart tongues 5.5 (Figure 3) forms a guide channel for the connecting pin 3.1 and thereby guarantees a non-rotatable connection of the slide unit S with the connecting pin 3.1 of the connecting member 3. The auxiliary slide member 5.1 further has a guide pin 5.4 on which the compression spring 5.3 and the main slide unit 5.2 are moveably positioned.
The support rods 4.2 and the auxiliary rods 4.3 of the top rod system are pivotally connected to the flanges of the auxiliary slide member 5.1 and the main slide member 5.2. At their respective other end, the support rods 4.2 are jointed to the top rods 4.1 and the auxiliary rods 4.3 are jointed to the support rods 4.2.
Figure 3 shows that the slide unit 5 apart from the two spread apart tongues 5.5 which form a guide channel for the connecting pin 3.1 includes a guide pin 5.4 which at a lower end has two laterally positioned constrictions 5.4.1. They cooperate with the closure mechanism in grip 6.
The grip 6 illustrated in Figure 4 includes a guide channel C for the lower tip of the guide pin 5.4 of the slide unit S and the closure mechanism is positioned therein.
The closure mechanism consists of a trigger button 6. l and a spreader spring 6.2 which in the closed condition of the umbrella engages the constrictions 5.4.1 of the guide pin 5.4 and thereby locks the slide unit.
When the umbrella is to be opened, the trigger button 6.1 is pushed. The spreader spring 6.2 of the closure mechanism thereby jumps out of the constrictions 5.4.1 of the guide pin 5.4. The thereby freed slide unit 5 advances in direction of the crown 2 along the telescopic shaft onto a preselected plane which is defined by the pivotal connection of the guide member 1.3 with the auxiliary slide member 5.1 of the slide unit 5 and a pivotal connection of the crown 2 with the connecting member 3.
Simultaneously, the rods of the curved telescopic shaft 1 are extended.
The slide unit 5 upon reaching the connecting member 3 opens the top rod system with the top cover 4 and rests against the connecting pin 3.1 of the connecting member 3 in that the connecting pin 3.1 slides into the guide channel of the auxiliary slide member 5.1. The tongues 5.5 of the auxiliary slide member 5.1 thereby guarantee an exact connection of the slide unit 5 with the connecting member 3.
Because of the construction of the connecting member 3, which limits the pivot angle of the crown 2 and enables the locking of the slide unit 5 on the connecting pin 3.1 of the connecting member 3, the upper part of the umbrella forms a rigid unit in the opened condition. The top rod system thereby remains stable despite the wind pressure and carries the top cover 4.
In the embodiment illustrated in Figure 2 with the split guide member 1.3, the wind force is transferred to the telescopic shaft not only through the support rods 4.2 of the slide unit 5 and the connecting pin 3.1, but also through the connection of support rods 4.2, auxiliary slide member 5.1, and guide member 1.3, and through the intermediate part 3.2 of the connecting member 3 parallel to the connecting pin 3.1. The intermediate member 3.2 of the connecting member 3 also prevents the independent unhooking of the slide unit 5 from the connecting pin 3.1 under increased wind pressure.
In order to close the umbrella, the main slide member 5.2 is pulled downwards in direction to the grip 6. The top rod system with the top cover 4 is thereby evenly folded about the curved telescopic shaft through cooperation of the support rods 4.2 and the auxiliary rods 4.3. The slide unit 5 unhooks from the connecting pin 3.1, slides together and tensions the compression spring 5.3. The lower end of the guide pins 5.4 of the auxiliary slide member 5.1 thereby slides out of the main slide member 5.2 by about 2 cm.
Upon further downward pulling of the main slide member 5.2, the slide unit S
is guided by way of the guide member 1.3 along the telescopic shaft 1 in direction of the grip 6, whereby the guide member 1.3 pushes on the latches 1.1. The stable connection of the rods of the telescopic shaft is thereby loosened and the rods are pushed into one another. The compression springs 1.2 are thereby pressed together.
At the end of the closing operation, the lower end of the guide pin 5.4 is pushed into the guide channel C of the grip 6 until the spreader spring 6.2 of the closing mechanism advances into the constrictions 5.4.1. The closing operation is completed.
In order to simplify the manufacture of the automatic umbrella with curved telescopic shaft, a further embodiment is illustrated in Figures 5 and 6. In this case, the slide unit 5 is slidably positioned on the curved telescopic shaft 1 as in conventional automatic umbrellas instead of beside the curved telescopic shaft 1.
The umbrella illustrated in Figure S, like the one described further above, consists essentially of a curved telescopic shaft l, the top rods 4.1 with the top cover 4, the slide unit 5 and the grip 6. The telescopic shaft 1 can thereby consist of two or three curved rods.
The rods of the telescopic shaft are guided in one another against rotation and are secured in their extended position by latches 1.1. -The rods are extended with the help of compression springs 1.2.
The connecting member 3 which has a shape curved in a direction opposite the one of the curved telescopic shaft 1 is positioned at an upper end of the curved telescopic shaft 1. The crown 2 is pivotally mounted on the connecting member 3 for rotation through a limited angle and in one direction only, whereby the pivot axis of the crown 2 is located higher than the plane E1 in which the connecting points of the top rods 4.1 with the crown 2 are located.
The slide unit 5 is slidably mounted on the telescopic shaft l and consists of the main slide member 5.2, the auxiliary slide member 5. l and the compression spring 5.3.
In contrast to the embodiment described in Figures 1 to 4, the support rods 4.2, which form a jointed connection between the auxiliary slide member 5.1 and the top rods 4.1, are of different lengths and are mounted to the top rods 4.1 at varying distances from the crown 2.
In order to guarantee the function of the slide unit 5, several units of the mutually relatively pivotable additional rods 4.4 and 4.5 are mounted to the top rods 4.1 or the auxiliary slide member 5.1 in such a way that the additional rods 4.5 are oriented at the same angle (3 to the auxiliary slide member S.1 as the support rods 4.2 at the opposite side of the opened umbrella. In the opened umbrella, the compression spring 5.3 evenly acts on the auxiliary slide member 5.1 because of the angle [3 between the additional rods 4.5 and the auxiliary slide member 5.1 as well as the respectively opposing support rods 4.2 and the auxiliary slide member 5.1, which prevents jamming of the slide unit 5 on the telescopic shaft 1. Furthermore, the additional rods 4.5 are upwardly bent at the end away from the auxiliary slide member 5.1 so that the connection axis with the additional rods 4.4 does not form any sharp corners.
The additional rods 4.5 or the respectively opposite support rods 4.2 are jointedly connected with the main slide member 5.2.
The grip 6 mounted at the lower end of the telescopic shaft 1 is ergonomically shaped so that a single comfortable grip allows automatic correct positioning of the opened umbrella.
When the umbrella is to be opened, the trigger button 6.1 in the grip 6 is pressed. The thereby freed slide unit 5 jumps into direction of the crown 2 on the telescopic shaft 1. At the same time, the rods of the curved telescopic shaft are extended.
The slide unit 5 upon reaching the connecting member 3 opens the top rod system with the top cover 4.
In order to close the umbrella, the main slide member 5.2 is pulled down-wardly. Through the cooperation of the support rods 4.2 and the auxiliary rods 4.3, the top rod system with the top cover 4 is evenly folded about the curved telescopic shaft. The slide unit 5 is pushed together and tensions the compression spring 5.3.
When the main slide member 5.2 presses on the latch 1.1, the stable connection of the rods of the telescopic shaft 1 is loosened and the rods are pushed into one another. The compression springs 1.2 are thereby compressed. When the main slide member 5.2 reaches the grip 6, a closing mechanism is triggered and thereby the closing operation completed.
