Description

2-6 -2

  The invention relates to an umbrella comprising a cover that can be opened and closed by means of a nut, a detent member that holds the nut in the position

  open cover and a mast consisting of a higher segment

  and a lower segment and which can be folded by means of a folding joint, one of the segments being provided with a projection, which extends beyond the folding joint and presents the shape of a rocker that serves as an arm

  locking the folding joint, and engages in the

  lOtre segment (the lower segment or the upper segment) and form inside, alternately meeting the wall

  this segment by its flanks, the two limit stops

  which define the two extreme positions

  mes of the folding joint, the rocker can be locked in its two extreme positions and possibly also in one or more positions located between the two extreme positions, by means of a lock which can be

  cleared with a button that can be operated manually.

  Such a parasol mast folding mechanism is already described, for example, in DE-U-1 880 393. Insofar as the umbrella representative of the kind does not emerge from

  this earlier publication, this parasol is known, for example

  No. 2,863,466 and 2,863,468 (S.N. Small), the last two documents cited in particular already describing spring-loaded latches and buttons that are associated with the folding mechanism. All of these prior publications, as well as all known prior art have in common the fact that the folding mechanisms are apparent and, therefore, very exposed to moisture, dust and dirt and , therefore, to corrosion and that by

  elsewhere, they represent by their angles and edges

  risk of injury when handling the umbrella.

  In the folding mechanism described in the aforementioned DE-U, this

  mechanism is, for example, enclosed inside the mast when

  that the latter is right. But, to bend the mast, it is necessary first to unscrew the upper segment of the folding mechanism sufficiently to be able to pivot it beyond a locking cam provided on the lower segment, then must screw it back from the unscrewing stroke while the mast is in its folded position and that the folding joint is apparent. In addition, this mechanism requires an interruption in the wall of the lower segment to receive the projection of the upper segment which serves as a locking arm, so that here too, moisture, dust and dirt can

  o10 to enter the folding mechanism and the cavity

  mast, from the top and laterally through the opening

  ture. In addition, here too, one is exposed to the risk of injury due to the apparent sharp edges of the folding mechanism. To overcome these drawbacks, the object of the invention is to improve an umbrella of the kind previously defined in such a way that neither moisture nor dust nor dirt can penetrate into the folding mechanism and hence from the inner volume of the mast, not even in the folded position of this mast, and in such a way that, in particular, no sharp edge or angle of the folding mechanism protrudes into this position, so as to avoid

  injuries when using umbrella.

  According to the invention, this problem is solved by the fact that the rocker, having the configuration of a spur head, is fixed rigidly in one of the segments and protrudes, with possibility of rotation, into the internal cavity of the wall of the other segment, which is closed over the entire turn, and in that the latch is pivotally mounted in the oscillation region of the latch in such a manner that the latch blocks the latch under the action of a spring and can be removed from this blocking position by means of the button against the action of this spring, the latch leaving the rocker the freedom to move laterally inside the cavity of the wall during the inclination movement of the upper segment. In this way, an umbrella of the type defined above is produced whose folding mechanism is completely enclosed in the mast both when

-3-

  the latter is straight only when it is folded, since

  The element which acts as a locking arm for one of the segments of the mast moves in a pivoting manner exclusively inside the mast cavity without this necessitating a through-opening through the wall of one of the mast segments. segments. Moisture, dust and dirt can not infiltrate the bending mechanism and hence the cavity of the segments. Corrosion or even total seizure of

  bending mechanism by rust, and the difficulty of

  or the impossibility of folding, which are the consequences

  these, are thus avoided as well as the deteriorations by corrosion in the mast. In addition, the mast or the cover

  can be easily bent or angled at any time.

  Since even when folding the mast, no edge or protruding angle is formed in the fold region,

  also avoids the risk of injury.

  An advantageous embodiment is obtained in that in the two extreme positions of tilting, the spur head abuts on the open end of the lower segment or upper segment by a narrowed portion which

connects to its head profile.

  Another advantageous embodiment is

  characterized in that the spur head is provided with a

  by which the rocker is supported in addition from top to bottom on the end edge of the lower segment or the

  upper segment in the extreme folding position corres-

  laying in blocking position III.

  According to another preferred embodiment, the rocker can be locked by its tooth or its spur tip between the inner wall of the segment and the flanks of the retaining tooth

  lock, thus being held on both sides.

  It is possible to advantageously obtain intermediate positions between the two extreme positions of the folding mechanism without particular additional expense by causing the rocker to engage with its tooth or spur tip in a groove. the retaining tooth

  lock, in the lock position II.

  According to another advantageous embodiment, the lock can be constituted by a lever with two arms, one of the lever arms constituting the retaining tooth, while the other lever arm forms, by leaning against the inner wall of the segment under the load of the spring, the stop of

limitation of rotation of the lock.

  In another advantageous embodiment, the button can be guided movably in translation in the wall of the segment and, being supported by force action against the lever lever lever arm, it is maintained so as not to fall outside. , by the latter in his starting position

  in which it emerges outside the wall of the segment.

  Another particular advantage which relates to an additional means of closing the bending region of the mast is obtained by the fact that the projection or the lever, which constitutes a lever end of the upper or lower segment, consists of a metal plug or synthetic material which is force-fitted into this segment and stopped in this segment by means of a transverse pin and by the fact that this pin serves at the same time as a hinge axis for the latching member which maintains the walnut cover in the open position, the nut covering in

  same time by its extremity forming the rod the ends or-

  green of the upper or lower segment in the

  open and snapped position of the cover.

  The invention will now be described in more detail with reference to an exemplary embodiment shown in the accompanying drawing, in which: FIG. 1 represents the upper part of an umbrella, with its open cover and its right mast or its folding mechanism in the blocking position I; FIG. 2 represents the upper part according to FIG. 1 but with the mast folded in the blocking position III, and after rotation of the mast or of the column; Figure 3 shows the upper part according to Figure 1 but rotated 90 around the erect mast, in the locking position I;

  Figure 7 but with the mast bent to the extreme, in the position

Blocking III.

  The umbrella of the type in question includes a cover

  D composed of a blanket frame having

  branches or whales and props 1, as well as a canvas 2 suppor-

  by this frame. The whales and stays 1, of which only one pair is represented in FIGS. 1 and 2, for the sake of clarity of the drawing, are articulated, in a star arrangement, respectively on the crown 3 and on the

  control 4 of the cover D. The nut 4 is mobile in trans-

  upwards and downwards on a hollow mast 5, so that, when the nut 4 is raised, the cover D extends and opens (see Figure 1), while, when When the nut is lowered, the cover folds in a position parallel to the mast 5, that is to say that it closes (not shown). The crown 3 and the fabric 2 of the cover are attached to the upper end of the mast 5. The

  mast 5 is demountably supported at its lower end.

  in a vertical tube, not shown, a mat, or it can also be attached directly to the mast. The nut 4

  can be locked in the open position of the cover

  re D by means of a ratchet 6 that can be unlocked manually

  or it can be locked by the fact that it is pushed back, a little higher than represented in FIG. 1, beyond the plane X of the neutral point of the pivoting movement,

  until it bears against a stop 7.

  In order to obtain the inclined position of the cover D which is shown in FIG. 2, the hollow mast 5 is provided with a folding mechanism K and, for this, it is composed of two tubular parts, namely of an upper segment 5 'and a lower segment 5. The folding mechanism K comprises a folding hinge 8 which connects the upper segment 5' to the lower segment 5 "with the possibility of inclination. The folding mechanism K is associated with a locking device 9

  who can block it in the open position of the cou-

  right or right (FIG. 1), in the inclined opening position (FIG. 2) as well as possibly in another intermediate position of opening more flat. This locking device can be unlocked by hand, with a T button, when you want to tilt the blanket D or rotate it parallel to the mast. The folding mechanism K and the

  blocking device associated with it, and which is

  killed by a latch 9 and its release device, are housed in the inner volume of the upper segments 5 'and

  5 ", so that, from the outside, they appear

  are locked away and thus protected from the effects of bad weather, corrosion and fouling and that, moreover, they do not protrude from the mast 5 so that, finally, this removes the risk of injury

in the use of the parasol.

  For this purpose, the upper segment 5 'is engaged in the lower segment 5 "by a spur-like projection 5a which projects beyond the hinge 8, so that the projection 5a can oscillate in both directions at the manner of a rocker within the limits of the inner wall 5d of the lower segment 5 ", by the two sides or sides 5b of the spur head 5c and, when the flanks 5b, 5b abut against the inner wall 5d, it s 'establishes two diametrically opposite pivoting movement limitation stops A' and A 'for the upper segment 5', the locking of the projection 5a by means of the latch 9 in its abutment positions A 'and A "ensures immobilization of the 5a projection in the direction of clockwise and in the opposite direction, in that the tip 5e of the spur is blocked between the inner wall 5d and -7-

  the flanks 9 ', 9 "of a retaining tooth 9a of the latch 9 (FIG.

  res 5 and 8). The blocking of the protrusion 5a or of the tip 5e of the spur between the sidewall 9 'and the inner wall 5d corresponds to the blocking position I shown in FIG. 5 and the blocking of the projection 5a or the 5th point of the spur between

  the flank 9 "and the inner wall 5d define the position of

cage III of Figure 8.

  The lock 9 is preferably constituted by a

  lever with two arms and has a transverse axis 9b oriented

  salty to the articulation 8, that is to say, which cuts this articulation in cross. While the lever arm of the latch 9 constitutes the retaining tooth 9a, the other lever arm 9c of the latch 9 serves to press this latch against the inner wall 5d against the rotational force of a spring F , as well as to make it cooperate with the button T already mentioned. The spring F is preferably a torsion spring comprising branches F 'and F ", the branch F' bears against the inner wall d, while the other arm F" bears against the lever arm 9c of such that the lever arm diametrically opposed to the first, and which forms the tooth 9a is normally held elastically and with the possibility of yielding under the force in the holding position relative to the tip e of the spur, which is shown on Figures 1 and 4. Among the locking positions I and III described above, the position I corresponds to the mast 5 erected, straight or not folded (Figures 1, 3 and 5), while the position III defines the mast folded, with the cover D inclined at a corresponding angle (Figures 2 and 8). Between the two blocking positions I and III, and as can be seen for example in FIG. 7, one or more intermediate blocking positions can still be provided which correspond to the blocking position II, thanks to the fact that the retaining tooth 9a of the lock 9 has a groove 9a 'or more grooves of this kind in which or in which the projection 5a or the spur tip 5e of this projection is locked under the action of the spring. Despite the low freedom of movement existing in the inner cavity of the mast 5, it is still possible to incline the cover D with respect to this mast less strongly than in the

2 6 1 2 5 5 1

- 8 -

  extreme inclination position according to Figure 2, if desired. The projection 5a has, in its shoulder directed towards the head 5c of the spur, a notch 5f by which it rests from top to bottom on the terminal edge 5g in the inclined locking position III of the mast 5, that is to say still in addition to the support determined by the oscillation limiting stop position A ", ultimately leading to an advantageous improvement in the stabilization of the mast 5 in its

bent position.

  To obtain an inclined or horizontal position of the cover D and the corresponding position, folded or erected, of the mast 5, it is first necessary to actuate the button T. This button is mounted movable in translation in the lower segment 5 ", transversely to the axis 9b of the latch 9, in the wall of the lower segment 5 "and is supported by a base T 'against the lever arm 9c of the latch 9. This base T' holds the button T against the wall internal d in the rest position according to Figure 4, in which position it is applied by the lever arm 9c loaded by its spring, so that it is not likely to fall from the lower segment 5 ". press the button T with a finger with one hand, the latch 9 rotates against the force of the spring until it abuts against the inner wall d by its lever arm 9c. In this position, the retaining tooth 9a of the lock 9 is spaced from its locking position relative to the point 5e of the spur (Figure 6), so that with the other hand, we can tilt the projection 5a, in

  folding the upper segment 5 ', in either direction

  desired, that is to say to place it in the positions shown, that is to say a straight position of the mast 5 (Figures 1, 5), or a folded position of the mast 5 (Figures 2, 7 or 8 respectively). When the desired position has been reached, it suffices to release the button T. This has the effect that, under the action of the spring F, the lock 9 is returned to the starting position shown in FIG. 4, causing the button

  T, the retaining tooth 9a returning at the same time in its posi-

  in relation to the protrusion 5a or, with respect to the spur tip 5e of this projection, as shown in FIGS. 4, 5 (locking position I in which the

  cover D is right) or in figure 8 (position of

  cage III in which the cover D is at its extreme inclination) or in Figure 7 (blocking position II in which the cover D is less inclined). The protrusion 5a ispreferenceconstituted by a plug of metal or synthetic material resistant to impact and rupture, force-fitted into the upper segment 5 'and stopped in this segment by a transverse pin 10 (Figure 4) and is provided with an abutment base 10 'which defines the fitting depth. As can be seen in Figures 4 and 5, the transverse pin 10 can at the same time advantageously serve in addition to hinge axis for the pawl 6 which locks the nut 4 when the cover D is open. For this purpose, there is provided in the body of the plug a recess 5h in which the pawl 6, which has the shape of a lever with a single arm is engaged so that the lever, mounted on the transverse pin 10 by means a

  hinge ring 6b, has a sufficient oscillation

  7, the pawl 6 needs to be able to push its stop tooth 6c in the upper segment 5 'to release the nut 4. A torsion spring 11 wound around the hinge ring 6b maintains the pawl 6 in the stop position shown in FIG. 5, in which the pawl 6 is engaged in a stop slot 4a of the nut 4, while passing through

  a slot Si of the upper segment 5 '. The depth of engagement

  of the stopper tooth 6c in the stop slot 4a of the nut 4 is limited by an abutment tooth 6d, the torsion spring 11 clinging behind the pawl 6 by a branch 1la bent hairpin, by loading the ratchet into

  the opposite direction of that of clockwise. The dis-

  The position and the rational configuration, described above of the folding mechanism K, in combination with the nut 4 and with its pawl 6, still have the advantages that, at the same time, the nut 4 covers the open ends 5k of the upper segments 5 'and lower 5 "when the cover D of the umbrella is open in a straight or inclined position, that is to say when the mast 5 is straight

- 10 -

  or folded, thus protecting these ends from moisture and dust as well as the risk of injury. In addition, in the two extreme tilting positions of the upper segment 5 '(FIGS. 5 and 8), the spur head 5c bears, Spar a narrowed portion 51, against the open end 5k of the

  lower segment 5 "This narrowing 51 results from the

  rounded head 5c spur, by which this head connects

  from to the body of the cap above the level of the joint

  The abovementioned support provides additional stabilization

  of the folding mechanism with respect to abutments A 'and A "of limitation of the pivoting which have already been described, the supports 5k, 51 being respectively diametrically opposed to the

  stops A ', A "with respect to the folding joint 8.

  The projection 5a could as well be housed in the

  lower segment 5 "and protrude into the upper segment

  5 'with the possibility of movement relative to this segment, to cooperate with the lock 9 which, in this arrangement would be found in the upper segment 5' and which could again be actuated by means of the button T, also mounted in the upper segment 5 '. The kinematics described above with respect to the upper 5 'and lower 5 "segments can therefore be considered as a" reversible "arrangement without this requiring a more complete explanation.
