Description

The invention relates to an automatically opening and closing, pocket-sized shortenable umbrella with one arranged in the umbrella handle first triggering device for the opening process and a second triggering device for the closing process, one arranged in the umbrella handle Trigger button for joint, timed actuation of the trigger devices, a telescopically shortenable umbrella stick with an umbrella crown, a sliding roof slide and one roof rods formed by roof rod units, a first spring drive to open the umbrella, which comprises a compression spring arranged in the umbrella stick, which pushes out the umbrella stick along with the opening process, a second spring drive for closing the screen, which in the roof rod units Integrated tension springs that go along with the opening process be tensioned, a rope with a rope, the rope on the roof slider attacks and ends at a slidably mounted in the umbrella stick Rod and a pawl arranged thereon with the release device cooperates, the pawl by means of a, acting on a locking member Hook nose is lockable.

A screen of this type is for example in the American patent US 54 92 140 A described. Umbrellas of this type are special to operate easy because both opening and closing are automatic simply by pressing a trigger button. On the other hand, this is Operating advantage but also with a significant constructive and additional costs associated with the for the automatic opening and closing process required mechanisms as well as for their triggering and unlocking, all of which are continuous with each other and against each other are to be coordinated. These mechanisms are in the known double automatic Opening and closing types very complicated, essentially in and structures centered around the umbrella stick that are used in the manufacture difficult to assemble and also hardly or for the purpose of repair are not accessible at all. This as well as a certain lack of functionality, in particular the locking and unlocking mechanism assigned to the closing process, results from the fact that these mechanisms are not only within of the very cramped installation space in and around the umbrella stick miniaturized are and are under considerable spring pressure, but that both the bondage as well as the release of the tensioned stock telescope exclusively between the umbrella stick and the umbrella handle and that Cable gear in pawl holding pawl on itself is a rigid link, the locking link, on the other hand, is a transverse movable catch element.

The invention is based on the object, a double-automatic To improve the opening and closing screens of the type defined at the outset, especially the locking and unlocking of the cable gear to design more reliable and the concentrically compressed Structure of the release and unlocking of the opening and closing mechanism loosening up and arranging, dividing and training that it is stronger and easier to assemble and disassemble enables.

This object is achieved in that the second Tripping device cooperating with the pawl in the Umbrella stick axis has movable unlocking slide as well as one that can be moved synchronously with it, with the release button cooperating pawl, and that this slidable Arrangement depending on the insertion and extension of the umbrella stick alternately in the ready-to-fire position the pawl and the release button engage towards the pawl towards and out of it, into an ineffective neutral position.

This results in a significant improvement in an automatically opening one and closing screen of the type defined above, both structurally as well as in the function, in the production and functional safety, Assembly and disassembly ability. Due to the stick-centric and at the same time compliant Floor-parallel arrangement and displacement of the unlocking and the second Tripping device and its compliant engagement and disengagement in and out of it Action positions with the release button or with the pawl and its hook nose there is a substantial loosening and therefore also more robust, more stable structuring of the tightly packed mechanisms for the opening and closings away from the extremely unfavorable, cramped layout space in the hollow of the umbrella stick. Only the remains Pawl and its unlocking of the locking mechanism. The locking and unlocking The opening mechanism is separate from the closing mechanism more spacious room moved away from the umbrella stick with double functional inclusion the sliding trigger button in its functions as a trigger element for opening and closing as well as a control slide or coupling element for the continuous engagement and disengagement of the release of the cable pull pawl and their hook nose. The closer and opener mechanism works consequently in a separate arrangement and effect Loosening of two groups in the continuous functional sequence the opening, closing and stick shortening process can be coupled together and are separable from each other. Accordingly, everyone is included Components can be designed to be more stress-resistant and functionally reliable, and moreover also easy to install and, if necessary, easy to replace.

A particularly advantageous embodiment of the function of the Invention according to the main claim results from the fact that the release button slidably guided - the locking member for receiving and Locking the hook nose is tubular in a cavity and is arranged coaxially to the umbrella pole axis and on the umbrella pole supports, -the second release device with the unlocking slide and the pawl are combined into a structural unit, the unlocking slide guided in the cavity and towards by a spring the hook nose of the jack is biased and when closed and shortened Umbrella via a stop on the roof slider formed on a side arm is supported and the pawl on the arm can be pivoted about an axis stored and designed as a two-sided lever, one lever arm intended for the attack of the release button during the closing process and its another lever arm with a locking hook for locking the unlocking slide is provided at a distance from the hook nose, so that during the opening process the first release device by pressing the release button releases the umbrella stick, the front of the unlocking slide is held by the locking hook at a distance from the hook nose and the lever arm enters the effective range of the release button during the closing process by pressing the release button again the locking hook is released and the unlocking slide engages with the hook nose and the pawl releases from the locking member and when shortening the umbrella stick when relaxed Tension springs tension the compression spring and the hook nose is locked in the locking element becomes.

This results in a particularly advantageous embodiment of the invention in connection with the first triggering device in that this triggering device interacts with the sliding roof.

An advantageous embodiment of the mechanics of the second triggering device can be achieved in that the locking hook interacts with the stop, the one on the underside of one connected to the umbrella handle, the umbrella stick encompassing retaining bush is provided.

This provides a particularly reliable design of the cable-pull mechanism achievable that the rope attacks the other end of the roof slider or over a rope pulley on the roof slider and connected to the umbrella crown is.

According to a further advantageous embodiment of the invention a particularly stress-resistant, reliable training of Cable lock and unlock by the fact that the pawl on one the rod attached or molded U-shaped hollow profile with radial resilient game is stored and the locking member as one in the stick end inserted socket with a stock-centric stop ring for locking the hook nose is formed.

This results in a further advantageous embodiment of the cable lock in that the hollow profile when locking the pawl with an injection molded end immersed in an input hole of the locking member and is supported in it on a bevel adapted to the pointed end, as soon as the hook nose hooks behind the stop ring.

Another advantageous design feature results in a particularly stable, simple and easy to assemble and disassemble arrangement and training the cable release mechanism in that the Unlocking slide from a displaceable in the cavity of the locking member Piston is formed with an attached hollow cylinder, the Hollow cylinder facing the hook nose.

According to another advantageous design feature, the mechanics of the second trigger device as a functional unit and rationalize by having the piston within a slot a non-slip cross pin is guided and attached to the hollow cylinder opposite end by means of a plate-shaped disc and one attached to it adjoining compression spring is supported on the bottom of the umbrella handle, and that at the Washer which is mounted in a cavity of the umbrella handle and protruding arm.

The automatically opening and closing umbrella has a telescopic shortenable floor 1 and a collapsible and / or sliding Roof D to be kept in the closed state in pocket format to be able to. That carried by a roof linkage 2 and provided with a cover 3 Roof D has several rod units 2 °, each in one star-shaped arrangement around the stick 1 both at the top of the stick 1a sitting crown 4 as well as on a sliding on the stick 1 up and down Attack the roof slider 5 in an articulated manner. The respective linkage units 2 °, from only one is shown in the drawing for the sake of clarity each include a suitable joint assembly of roof poles 2 'and struts 2 ". One of the struts 2" is in each case on the roof slide 5 articulated so that the roof D is opened by an upward movement of the roof slide 5 can be closed and closed by moving down with the help a spring drive F1 and F2. The spring drive F1 is used for this automatic telescoping of the stick 1 and associated opening of the Dech D and Spring drive F2 provided for its automatic closing, the latter for example in the form of several spring balancers F2 'in the linkage units 2 ° can be built in that they constantly strive to the roof linkage close. However, the spring force of all spring balancers F2 'is dimensioned so that that, as will be described in more detail below, it is far below the Spring force of the spring drive F1 for telescoping the stick 1 and Opening of the roof D is. The axis of the stick 1 is labeled X.

The stronger spring drive F1 has the shape of a stretchable in stick 1 embedded compression spring spiral F1 ', which ends at the crown 4 and the other end is supported at the bottom by a fixed stop 1b. That on thus formed spring telescope 1 'has the constant endeavor to expand. In order to use this effort to open roof D at the same time, is a reversing gearbox S structured according to the pulley principle provided between the stick 1 and the slider 5 actuating the roof D. This energy-saving transmission is preferably a double roller train with a rope pulley 6 on the crown 4 and such a pulley 7 on the roof slide 5 and with a cable pull S 'running over it. This is fixed at one end to an anchor 4a on the crown 4 and the other end with a push rod that can be moved in floor 1 8 connected directly or via a train compensation Z. At the free end 8a the push rod 8 or one molded or connected at the end 8a U-hollow profile 9a is a bolt in the form of a radial ↔ resilient Pawl 9 embedded within the hollow profile 9a fixed, see above that the pawl 9b with a hooked lug 9b swings out of it Spring out the hollow profile 9a as well as against the bottom 9a 'of Profile 9a can swing back with lateral guidance through the Profile leg 9a "(Fig.5).

The pawl 9 interacts with a "rigid" locking member 10 of a release lock A2 assigned to the closing process by, as can be seen from FIGS. 1 and 2, in the closed, shortened state of the screen with the hook nose 9b inside a cavity 10a of the socket-shaped locking member 10 is hooked behind an annular shoulder 10b. The locking member 10 is inserted into the stick end 1c and its depth of penetration is determined by a flange 10c supported on the stick end 1c. Accordingly, the pawl 9 is not a rigid bolt that is gripped and locked by a radially movable or flexible locking member, but rather a kind of resilient harpoon that anchors itself in the "rigid" locking member 10. In order to make the centrically exact self-engaging of the resilient pawl 9 and its displacement security in its latching in the rigid locking member 10 particularly functional, the U-hollow profile 9a, which rests the pawl 9, as shown in FIGS. 2 and 3 can be seen to have a tapered end 9a "'with which, when the pawl 9 is locked in the locking member 10, it dips so deeply into its entry hole 10d and is held there by an adapted bevel 10e until the hooked lug 9b of the pawl 9 makes the hole 10d has passed and is locked behind the annular shoulder 10b. In this way, the cable reversing gear S between its fixed points 4, 4a and 9b, 10b in the compressed, shortened state (FIG. 1, 2) of the screen is a spring-loaded one Stock telescope 1 '. As far as it is let in and movable in the floor 1, the cable pull reversing gearbox S can, in order to avoid an undesired frictional connection with the compression spring F1' also located in the floor 1 Opener drive with a telescopic cocoon TK coordinated with the stock telescope 1 in terms of length, extension and insertion. Furthermore, the already mentioned tension compensation Z can be placed in coordination with the push rod 8 so that it comes to rest in the pushed-together stick 1 between the push rod 8 and the rope pulley 6 seated on the crown 4. The tension compensation Z enables the bridging of dimensional tolerances in the structure of the stock telescope 1 'and the roof kinematics connected to it, in particular, however, that in this way the stock telescope 1' with the roof D open and the stock telescope 1 'extended. can be extended to its full length (Fig. 6,11). The tension compensation Z preferably consists of a cylinder-piston guide with a sleeve Z 'as a cylinder, a piston bushing Z "guided therein and a compression spring Z * which resiliently supports this against the sleeve Z', the sleeve Z 'by means of a rivet Za engages the thrust rod 8, while the piston-socket Z "is connected to the cable S 'by Z through the bush this" threaded to a node S * _b to a flange of the bushing Z Z "tensile load is applied (Figure 10 , 11).

The handle 12 has a central retaining bush 12a, radial thereon molded webs 12b and a cylindrical shaft 12c. This is connected to the holding bush 12a by the webs 12b, so that there are several radial hollow chambers extending over the length of the handle 12d in the handle 12 result within the space between Bushing 12a and shaft 12c. In the holding bush 12a is the Stick 1 inserted with its lower end 1c and detachable by means of a Cross pin 13 fixed by this through the shaft 12c, two opposite Webs 12b, 12b and in the middle through the holding bush 12a and through the stick end 1c reaches through (Fig. 8). The cross pin also grips 13 but also still fixed by the bush-shaped locking member 10 the trigger device A2 and one through a slot 14a in the locking member 10 displaceable piston 14 in the sequence Piston guide K of the triggering device A2 described in more detail. Accordingly, stick 1, handle 12 and locking member 10 are in one fixed to each other and against each other by means of cross pin 13 and also this forms with its passage through the slot 14a ° also a limit stop for the displacement movement of the piston 14 in the cavity 10a of the locking member 10.

Another cylindrical cavity 12e in the handle 12 extends from the end of the stick 1c or a flange 10c of the locking member which bears against it 10 to the bottom 12 f of the handle 12. The bottom 12f is from a cover 12g formed by means of a clip connection 12h is releasably clipped onto the shaft 12c, so that the Cavity 12e and cavities 12d and the mechanisms housed therein after loosening the lid 12g very simple and easy for the purpose of Assembly and repair are accessible. The upper end of the handle shaft 12i is open and serves as an insertion and extension opening for the slide 5.

The socket-shaped locking member 10 of the trigger device A2 is loose and inserted again in the end of stick 1c and as already described fixed. It also forms the upper edge already described fixed stop 1b for the compression spring spiral F1 'and extends to the lower end 1c of the Stockes 1, where it is supported by means of the flange 10c. The Locking member 10 is in this way during assembly and repairs easy to install or replace with the plug-in method tailored coordination of the required coincidence positions of his Ring shoulder 10b to the resilient pawl 9 and its fastening hole on the cross pin 13. The same applies to the other in Handle 12 housed mechanics.

The release required to initiate the closing process the resilient pawl 9 is carried out by an unlocking slide in the form of a in the cavity 10a of the locking member 10th displaceable hollow cylinder 15, which in the course of an upward directed displacement movement of the piston guide K over the Hook nose 9b of the pawl 9 and pushes it out of it Locking behind the ring shoulder 10b of the locking member 10 disengages (Fig. 4,5). The hollow cylinder 15 is on the piston already described 14 molded or fixed to a pin 14a of the same. The Piston 14 is part of the piston guide K. This is by means of pin-slot guide formed by the transverse pin 13 and the slot 14a ° within the locking member 10 to the extent of the length of the Slot 14a in a certain shift limit up and down slidably with the top slot end 14a 'the outermost Displacement limit of the piston guide K out of the locking member 9 and the lower slot end 14a "the extreme shift limit ins Lock member 10 result. The piston 14 is on a plate-shaped Disk 14b fixed or molded, one of which is parallel to the Piston 14 extending arm 14c protrudes so that it parallel to the wall of the handle shaft 12c freely movable in one of the hollow chambers 12d of the handle 12 protrude. The arm is there 14c with its upper edge 14c * in frictional engagement with the roof slide 5 (Fig. 1,2). On the arm 14c is a double-armed pawl 16, which around an axis 17 is pivotable and by a torsion spring 18 in the closed and shortened state of the screen (Fig.1,2) with an edge 16b 'of lower lever arm 16b b in contact with the cylindrical outer surface the holding bush 12a is held. The lower lever arm 16b is provided with a locking hook 16b '' with which it is in the out Fig. 3 apparent ready position for the closing process on the lower edge 12a "or an attached stop ring 12a 'of the holding bush 12a hooked. With her upper lever arm 16a, the pawl 16 interacts with the release button 11 as soon as the pawl 16 from the piston guide K into the stroke H of the button 11 pushed in and can be grasped by this, the lever arm 16a with the locking hook 16b "out of engagement with the lower edge 12a "or with the stop ring 12a '. The displacement of the Pawl 16 in the stroke H of the trigger button 11 takes place under Effect of a compression spring 19 between the plate-shaped disc 14b and the bottom 12 f of the handle cover 12g is clamped. In this way there is a center in the stick axis X piston guide guided in the limit of the pin-slot guide 13, 14a K the pawl 16 and the unlocking hollow cylinder, however, 15 with a Direction of displacement towards the end of the handle 12 under the action of the roof slide 5 and in the opposite direction under the action of the spring 19 to the release button 11 in the required non-rotatable alignment of the arm 14c and the pawl 16 with respect to their engagement in the stroke H of the release button 11. In addition to this non-rotating stroke, there is also in particular a rectified, conformal stroke of the parts 14, 15, 16, 17, 18 of the release device A2 and the unlocking assigned to it in a construction unit like Feed unit (Fig. 2,3,4,5). This construction and shear unit V is also out simple and robust parts designed and assembled to be one high functional safety guaranteed and in the insertion process with few Handles can be installed and just as easily disassembled and exchangeable after removing the handle cover 12g from the handle shaft 12c and Loosen the cross pin 13 (Fig. 4,5). The insertion limit of the construction and Instead of the slit stop 14a ", the displacement unit V can also take place by that the disc 14b directly abuts the flange 10c of the locking member 10.

The trigger button 11 is not only used to activate the already trigger device A2 described for the closing process, but also to activate those assigned to the opening process Release device A1 for the opening process. The Trigger button 11 is preferably simplified with the trigger device A1 and its unlocking assembled uniformly. It is in one with the stroke by means of a slide 11a H identical cavity of the umbrella handle 12 transversely to the stick 1 slidable in a groove 12h. The slide 11a encloses the stick 1 in the form of an oval ring such that it has the stick 1 can happen all around with enough sliding play and the button 11, starting from their basic position, into their release positions for the opening and closing process against the effect of a Move the slide 11a in the starting position to hold the spring 20 can. When opening, the button 11 snaps onto the slide 11a trained release lock 21 from a locking opening 5a of the roof opening slide 5, so that on the cable reversing gear S strained. Floor 1 released for telescoping with the accompanying opening of the roof D (Fig. 2,5). When triggered of the closing process, the button 11 locks the pawl 16 against Effect of the torsion spring 18 from its locking position (Fig.3) from the lower edge 12a "or the stop ring 12a ', so that the piston guide K under the action of the spring 19 the unlocking slide 15 over the hook nose 9b and thereby resilient pawl 9 from its locking on the ring shoulder 10b disengages with the associated release of the cable reversing gear S in the sense of the roof closing under the action of the springs F2 '.

The main functions of the screen are accordingly determined by

a) the automatic opening process of the roof D under the action of the spring drive F1 with the accompanying extension of the telescopic stick 1 and tension of the closing spring drive F2,

b) the subsequent automatic closing process of the roof D under the action of the closing spring drive F2, and

c) the subsequent shortening of the screen to pocket format by hand by pushing the telescopic stick 1 together with the associated tensioning of the opening drive spring F1 '.

In the opening process to be triggered by pressing the trigger button 11 the latch 21 lifts its catch in the roof opening slide 5, so that this from the cable gear S under Effect of the telescoping stick telescope 1 with accompanying Opening the roof D upwards into that shown in Fig.6 Location is moved. Since the cable gear S fixed in the locking member 10 is, the rope S 'runs over the roller 7 on the roof slide 5, the telescopic cocoon TK pushes apart and the roof closing springs F2 'are excited. At the same time, the roof opening slider is released 5 of the arm 14c, so that the parts 14th up to 18 existing sliding unit with the unlocking slide 15 and the pawl 16 under the action of the spring 19 Position according to Fig.2 in the position shown in Fig. 3 shifts. In it, the pawl 16 engages with the lever arm 16a in the stroke H the release button 11, but the pawl 16 still with their other lever arm 16b at the stop 12a'bzw. 12a "hooked and the unlocking slider 15 immediately before the hook nose 9b of the resilient pawl 9 comes to rest. The train compensation Z the cable-operated gear S is now tensioned (Fig. 11).

In the following, again by pressing the release button 11 The closing process of the roof D to be triggered pivots the button 11 Pawl 16 from the locking position against the stop 12a 'or 12a "against Effect of the torsion spring 18 so that the sliding unit with the unlocking slider 15 and the pawl 16 under effect the spring 19 moves another piece up in the Position shown in Fig. 4. In it the lower edge 14a "of the Pin slot guide 13,14a to the cross pin 13, the unlocking slide 15 slips over the hook nose 9b and lifts this in a radially resilient centering movement from the ring shoulder 10b of the locking member 10, whereupon the cable reversing gear S pulling the resilient pawl 9 on the push rod 8 upwards under the action of the roof closing springs F2 'with the rope S' now runs back over the rope pulleys 6,7 with a downward shift the roof slide 5 and folding the roof D. The tension compensation Z is now free due to the fully extended stick telescope 1 (Fig. 10). With the following shortening of the stock telescope 1 is the Umbrella graspable with both hands and with the handle end and crown part press together until the roof slide 5 with a Socket 5b in a correspondingly adapted receiving opening 12i of the handle 12 plunges with the concurrent impact of the Roof slider 5 on the arm 14c of the pusher unit with the release device A2 and the unlocking slider 15 and the Move to the ineffective neutral position according to the situation according to Fig. 1 and 2, in which finally the trigger lock again 21 engages in the locking opening 5a of the roof slide 5, with which again the roof opening together with the stretched stick telescope 1 is locked in the starting position according to Fig.1.

In it, the cable reversing gear S is again on the cable compensation Z relaxed (Fig. 10). The role 7 is on the rope S 'again unrolled below. The train compensation Z also comes again due to the length Matching the push rod 8 and its locking parts 9, 10 with respect to the shortened length of the stock telescope 1 immediately before to lie on the crown 4 mounted pulley 6 and the telescopic protection cocoon TK has moved again. The spring F1 'of the NC drive is again tensioned, the springs F2 'of the closer drive, however, relaxed. The Roof cover 3 preferably pulled into the roof frame without creases.
