Definitions
- This invention is generally in the field of umbrellas, and relates to s strutless- type umbrella.
- US 5,711,234 discloses a strutless umbrella which includes a central post, either an inner plunger or tube, a canopy assembly including ribs pivotally mounted on the upper end of the central post. Links connect the ribs to the inner plunger or tube. Movement of one of the ribs moves the plunger or tube which moves the remaining ribs. A latch pin holds the umbrella in the open position.
- US 5,638,846 discloses an umbrella having a simplified construction which dispenses with the stretcher members (struts) of conventional umbrellas and has one end hinged to the central portion of each rib.
- Said umbrella includes a runner axially slidable along the umbrella pole between a folded position in which the ribs can be folded against the pole, and an unfurled position in which the runner engages the ribs and holds them in the extended position.
- the runner comprises an upper frusto- conical portion engageable with the ends of the reinforcing portions of the ribs. It can be appreciated that according to US 5,638,846, the ribs are to be folded by gravity acting on their own weight, since there is no user activated mechanism for folding them.
- AT 231634 discloses strutless umbrella aimed at protecting from radioactive rain following nuclear disaster.
- the umbrella ribs extend into the umbrella crown into which being incorporated ' a guiding device placed inside the stick tube and operable from the umbrella's handle.
- the guiding device comprises an actuation rod passing upwardly through the stick tube, and a grooved plate mounted on the rod.
- the center ends of the canopy ribs formed in the shape of spheres enter the grooved plate.
- a pressure spring is mounted on the actuation rod and supported on its next end in the stick head which is mounted on the umbrella crown.
- strutless umbrellas developed by the inventor of the present application, utilize a canopy conducting mechanism, which may be useful for electrical umbrellas.
- the canopy conducting mechanism has short movement between open and closed states of the umbrella and is based on pin and slide joints between the umbrella ribs and between a canopy conducting member.
- strutless umbrellas are neater and more elegant when compared to that of umbrellas having struts. Furthermore, strutless umbrella enables a user to bring the canopy very close above his head, which may improve the protection the umbrella provides, especially in hard and windy weather conditions.
- strutless umbrellas have- no struts to help in lifting and lowering the ribs between deployed and closed states of the umbrella.
- the mechanisms for pivoting the ribs for lifting or lowering them are based on pushing and puling them through an extension of the rib body made between their pivot axis and the area above the top of the stick. Therefore, in these mechanisms the length of the extension of the ribs together with the dimensions of other parts of the mechanisms located above the top of the stick define a minimum to the possible diameter of the folded umbrella. Since said extension of the rib acts as a lever arm, it can be appreciated that the forces acting on both the extension and the pivotal connection of the rib are in an inverse relation to the length of the extension. The longer the extension is, the lower the acting forces are, and vice versa. Therefore, in order to reduce the acting forces, the lever arms should be extended respectively, resulting in enlargement in the diameter of the folded umbrella.
- the minimum diameter of the folded umbrella is the distance measured between the bent corners of two opposite ribs. This minimal diameter would be about 130% of the crown's diameter.
- the diameter of the actuation rod together with twice the wall thickness of the grooved plate adds to the lengths of two opposite rib extensions from pivot pin to sphere in defining a minimum possible diameter of the crown.
- the contact area between the plate and the ends of the ribs is pointed, since it is the area between a flat surface of the plate tangential to the sphere. As the acting forces are high, pressure between the surfaces becomes extremely high, which may result in accelerated wearing of both the surface of the plate and the spheres.
- the diameter of the pivot pin is about only 5% of the lever arm (i.e. the distance from the pivot pin to the sphere). Accordingly, the contact area between the pin and the apertures in which it pivots is very small, and thus the pressure between the contacting surfaces of the pin and the apertures will be high, causing accelerated wearing of the pivot connection.
- the present invention solves the above problems by providing a novel configuration of a rib assembly for strutless umbrella (having a pin and slide canopy conducting mechanism), enabling reduction of the umbrella diameter when in its folded state.
- This is achieved by providing at least one of the following configurations of the rib assembly comprised of a longitudinal rib body having a pivot member at its end, and a rib lever extending from the rib body: (i) the pivot member is located in a corner formed between the rib body and the rib lever; (ii) the rib lever extends from the rib body in an angle of between 110 - 160 degrees; (iii) the rib lever has a goggles shaped profile; (iv) the height of the rib body is similar to the max distance between the round surfaces of the rib lever; (v) the max thickness of the rib lever is certainly smaller comparing to the max distance between the rounded surfaces of the rib lever; (vi) the round sliding surfaces of the rib lever are substantially planner in a direction parallel to a pivot
- an umbrella rib assembly for use in strutless umbrella having a pin and slide canopy conducting mechanism, the rib assembly comprising a longitudinal rib body having a pivot member at its end, and a rib lever extending from the rib body, and being characterized in that the pivot member and the rib body together with the rib lever present a single piece of material, and the pivot member is located in a corner formed between the rib body and the rib lever.
- the material of the pivot member and the rib body may be a polymeric material.
- the rib lever extends from the rib body in an angle of between 110 — 160 degrees.
- the rib lever may have a goggles shaped profile.
- the rib lever preferably has rounded upper and lower sliding surfaces, with the height of the rib body being similar to a maximal distance between said rounded surfaces.
- the maximal thickness of the rib lever is preferably smaller as compared to a maximal distance between the rounded upper and lower sliding surfaces of the rib lever.
- the rounded surfaces are preferably substantially planner in a direction parallel to a pivoting axis of the rib assembly.
- the pivot member is formed as a pair of lateral protrusions protruding from a pivot point to form a pivoting axis from the same piece of material.
- a distance between the pivot member and the free end of the rib lever preferably does not exceed about 200% of the maximal distance between round upper and lower sliding surfaces of the rib lever.
- the configuration is such that the free end portion of the rib lever has a coin shape tapering towards the free end of the rib lever, or a coin shape truncated at the free end of the rib lever.
- the diameter of the pivot member is greater than about 20% of the rib lever's length.
- a strutless umbrella comprising a plurality of the rib assemblies, each configured as described above.
- Each of the rib assemblies is preferably pivotally mounted in a housing having a base part connected on top of the umbrella's stick and a cap part secured on top of the base part.
- a corresponding number of pairs of recesses is provided between the base part and the upper part, each pair of recesses accommodating a pivot axis of one of the rib assemblies.
- the free ends of the rib levers are located between upper and lower restricting members forming a slide in which rounded upper and lower surface of the rib levers can slide when the rib assemblies are forced to pivot upon a linear movement of the slide in line with the longitudinal axis of the umbrella.
- the upper and lower restricting members are secured to each other and to the upper edge of a rod passing through the stick, by means of a screw.
- a distance between the round surfaces of the rib lever is greater than a distance between slides which serve mirroring ribs.
- the rib assemblies preferably have gradually reduced thickness towards their distal ends resulting in flexibility of the ends of the rib assemblies useful for obtaining mushroom shaped canopy.
- Figs. IA to 1C illustrate, in partial vertical cross section view, three states during the operation of a canopy conducting mechanism of the present invention based on pin and slide joint;
- Fig. 2 illustrates a partial lateral cross section view of the canopy conducting mechanism in its state of Fig. IB;
- Fig. 3 illustrates a side view of an umbrella rib according to the embodiment of Figs IA to 2, made of one piece of material;
- Fig. 4 illustrates a top view of the canopy rib of Fig. 3;
- Fig. 5 illustrates another embodiment of an umbrella rib according to the present invention
- Fig. 6 illustrates the rib of Fig. 5 with the free end of its rib lever situated in a canopy conducting member
- Fig. 7 illustrates another embodiment of a rib according to the present invention.
- Fig. 8 illustrates a top view of the ribs and the base part of the housing in the embodiment of Fig. 7;
- Fig. 9 illustrates an isometric view of a cap of a rib housing, to be mounted on a base part;
- Fig. 10 illustrates an isometric view of the base part of the embodiment of Fig. 8.
- Fig. 11 illustrates in isometric another embodiment of a two-part housing connected on top of an umbrella stick.
- a canopy conducting mechanism of the present invention which in the present example is based on a pin-and-slide joint.
- the latter is of the type defining an elongated contact region between a pin (i.e., a cylindrically-like element with circular or other rounded base surfaces) and a slide plane, the contact region thus being a line along the cylinder-like generator.
- Figs. 1A-1C show, in partial vertical cross section view (taken at A-A of Fig. 2), three operational states, respectively, of the mechanism, and Fig. 2 shows a partial lateral cross section view (taken at B-B of Fig. IB) of the canopy conducting mechanism in its state of Fig. IB.
- a pin 300 of the pin-and-slide joint is actually the end portion of a rib lever 303 of an umbrella rib body 301.
- Pin 300 is also referred to in the context of the present invention as "the free end of the rib lever”.
- pin 300 has a coin-like shape, i.e. a cylinder of a relatively small height, namely having a diameter significantly larger than its thickness (measured perpendicular to the figure plane), and is tapered toward the free end of the pin. This feature can be seen clearly in Fig. 2.
- the pin 300 is mounted for sliding movement along a hollow cell 311 (will be referred to also as "slide 311") made in a canopy conducting member 310, which actually is a hub comprising a plurality of such hollow cells 311 arranged in a spaced- apart radial array about a common center.
- a canopy conducting member 310 is shown in its uppermost position above the umbrella stick (not illustrated), with the pin 300 forcing the rib lever 303 upwards, thus keeping the rib body 301 downwards, which corresponds to a closed canopy state.
- the canopy conducting member 310 moves down to the position illustrated by Fig.
- the pin-and-slide joint formed by the free end (“pin") 300 and slide 311 allows to convert the up-down vertical movement of the conducting member 310 into a pivoting movement of the lever 303 and the rib body 301 about the pivot member 302. It is appreciated that the rib lever 303 may be designed shorter than illustrated, and actually the free end (pin) 300 itself may function as a rib lever.
- Fig. 2 in the state illustrated by Fig. IB, the ribs 301 are in a mid location with the canopy partially opened and with the free end 300 of each rib lever 303 being maximally slid along the slide 311 in the direction of the central axis of the conducting member 310.
- Figs IA and 1C in which the free end 300 of the rib lever reaches its maximal opposite slid along the slide 311, i.e. its max distance from the center of the conducting member 310.
- the up-down movement of the conducting member can be achieved by a hub extension 312 (shown in Figs 1A-1C) extended into the stick of the umbrella.
- Figs. 3 and 4 illustrating side and top views, respectively, of an umbrella rib assembly according to the above-described embodiment of Figs IA to 2, and made of one piece of material.
- the rib assembly can be produced from plastic casting, as one (integral) unit comprising rib lever 303 and its free end 300, pivot members 302 from both rib's sides, and rib body 301.
- the rib body 301 itself may have recesses 304 from both its sides, thus reducing its weight with negligible lose of strength.
- the opposite end portion 305 of the rib body 301 can be made gradually tapered, such that its thickness at the end of the rib body 301 is sufficiently reduced as to make it flexible.
- the rib body 301 is forced to the arched shape illustrated by doted line 306, due to a stress exerted by the canopy fabric (not illustrated) which is dimensioned and designed in a mushroom shape, forcing the flexible ends of the rib bodies to bent downwardly.
- the stress exerted by the canopy fabric significantly increases the forces acting on the rib lever 303, on the pivot member 302, and significantly increases the pressure in the tangential contact between the round surfaces of the coin shaped free end 300 and the surfaces of the slide 311.
- the above-described umbrella rib construction includes several features which allow it to comply with extreme acting forces: the rib assembly has a pivoting axis defined by the pivot member 302 having a diameter greater than about 15% of a distance between it and the central axis of the coin shaped "pin” 300, and is furthermore integral (made from the same piece of material) to the rib body.
- the tangential contact between the round surfaces of the coin shaped "pin" 300 and the surfaces of the slide 311 is linear and not pointed
- the rib assembly has a massive lever structure 303 having a height (measured in the figure plane perpendicularly to the longitudinal axis of the lever arm) averagely greater than half its length and twice its width.
- the rib assembly has flat end 305 which is flexible in the direction perpendicular to the illustration plane, due to reduced thickness of the end of the rib body.
- the present invention provides an umbrella having a canopy conducting mechanism described above, wherein the rib bodies are made of a rigid material and have gradually reduced thickness at their distal ends resulting in flexibility thereof useful for obtaining mushroom shaped canopy.
- FIG. 5 there is illustrated another embodiment of an umbrella rib 1 according to the present invention.
- the figure focuses on the area of a rib lever 3 and its meeting area with a rib body 5.
- the rib lever extends from the rib body in an angle A.
- a pivot member 2 is located in a corner 4 formed between the rib body 5 and the rib lever 3.
- the rib lever 3 has a goggles shaped profile. This is identifiable by a valley 6 formed between two hills 6a and 6b.
- the hill 6a forms an upper round surface to be in tangential contact with a surface of an upper slide member aimed at preventing free pivoting of the lever upwardly.
- An upside-down hill 6c forms a lower round surface, mirroring said upper round surface 6a, to be in tangential contact with a surface of a lower slide member (not shown) aimed at preventing free pivoting of the lever downwardly.
- the height of the rib body 5 (the height being measured between the upper and lower surfaces 7 and 8 of the rib body 5 near its meeting area with the rib lever 3) is similar to the max distance between the round surfaces 6a and 6c of the rib lever 3.
- the depth of the valley 6 is preferably of the minimal value which still permits sufficient rotation of the canopy rib for approaching its fully deployed position.
- a mirroring valley 9 fulfills a similar function in the opposite rotation direction of the rib, i.e. permits sufficient rotation of the rib for approaching its fully closed position.
- the max thickness of the rib lever 3 (measured e.g. along line 10 between the opposite flat walls of the lever) is certainly smaller comparing to the max distance between the round surfaces 6a and 6c of the rib lever.
- the round sliding surfaces 6a and 6c of the rib lever are substantially planner in a direction parallel to the pivoting axis 11 of the rib.
- the pivot member 2 is formed as a pair of lateral protrusions from the lateral flat walls of the rib (only one is seen in this Figure) to form the pivoting axis from the same piece of material of the rib.
- a distance between the pivot member 2 and the free end of the rib lever 3 does not exceed about 200% of the max distance between the round surfaces 6a and 6c of the rib lever.
- the pivoting member 2 has a diameter greater than about 20% of the rib lever's length.
- the free end of the rib lever has a coin shape tapering towards the free end thus allowing to crowd together rib levers of a plurality of umbrella ribs closest to the umbrella's centerline axis.
- Fig. 6 illustrates the rib 1 of Fig. 5 with the free end of its rib lever 3 situated in a slide 20 formed in a canopy conducting member 19 constituted by upper and lower restricting members 21 and 22.
- the round surfaces 6a and 6c of the rib levers can slide when the ribs are forced to pivot upon a linear movement of- the conducting member in line with the longitudinal axis of the umbrella (i.e. as indicated by an arrow W).
- the max distance between the rounded surfaces 6a and 6c is grater than the distance (measured as the diameter of a tubular portion 23 of the restricting members 21 and 22) between slide's portions which serve mirroring ribs.
- the upper and lower restricting members 21 and 22 are two exemplars of the same part formed from plastic material and arranged to face one another to form the slide 20 in between.
- the parts are to be connected together by screw or bolt inserted through a hole 24 and passing through inside the tubular portion 23 to secure the conducting member to the top edge of an actuation rod (not seen) passing through the stick.
- FIG. 7 illustrates yet another embodiment of a rib according to the present invention.
- a rib 31 has a rib body 35 and a rib lever 33.
- the free end of the rib lever 33 has a coin shape truncated at the free end. It is to be noted that when the rib 31 is in a mid position between fully deployed and fully closed states of the umbrella, the free ends of the rib lever 33 reach their closest distance to the umbrella's centerline axis.
- Fig. 7 also illustrates, in a vertical cross section view, a base part 40 of a housing in which the ribs are pivotally connected.
- the base part 40 has a truncated conical profile, comprising a circular groove 41 allowing connecting the housing on top of an umbrella stick, and a plurality of vertically oriented gaps 44 allowing the ribs to fold closer to the stick.
- the diameter of the umbrella in its folded state will not significantly exceed a diameter D of the housing measured at its widest region.
- Fig. 8 illustrates a top view of the ribs and the base part of the housing illustrated by Fig. 7. Reference is made also to Fig. 10 illustrating the base part in isometric view from above.
- the ribs 31 are pivotally connected to the umbrella's stick
- the pivot connection is by pairs of protrusions 32 made from both rib sides near the end of the rib body 35 to form a pivot axis 32.
- the pairs of protrusions 32 are situated in respective pairs of recesses 42 made in the rib holders 46 which in this example are formed as elevated members of the base part 40.
- Each rib holder 46 contains two recesses 42 each for receiving a respective protrusion 32 of an adjacent umbrella rib body 35.
- a hexagonal tunnel 49 is formed in the bottom of the base part 40, through which an actuation rod (not shown) can emerge from the stick to join a canopy conducting member e.g. of the type 310 of Fig. 1, or 19 of Fig. 6, to be accommodated within the housing.
- each rib receiving space in the base part 40 contains a gap 44 formed between two rib holders 46 which are base part members elevating from the housing collar 58.
- the gaps 44 extend downwards the base part in order to allow the ribs approaching near the stick when pivoting towards a closed state of the umbrella.
- the base part 40 further has bores 58 made in the top surface of the rib holders 46, for receiving corresponding protrusions made in the bottom of the cap 62 (illustrated by Fig. 9).
- the connection between the bores 58 and the corresponding protrusions may be reinforced by screws each passing through a respective pair of protrusion and bore.
- the housing cap 62 may be connected to the base part as to secure the ribs by closing the recesses 42 from above thus preventing escape of the protrusions 32 from the recesses 42.
- Fig. 9 illustrates an isometric view of a cap 62, showing its bottom, which matches the top of the base part 40.
- the cap has pairs of recesses 42a, made in closures 46a, each closure 46a cooperates with a corresponding rib holder 46 such that when the base part is closed by the cap, the recesses 42 made in the rib holders 42 and the recesses 42a made in closures 46a form pairs of cylindrical spaces accommodating respective pairs of protrusions 32 of the umbrella ribs 31. It is to be noted that it is possible also to have recesses only in the rib holders 46 of the base part provided that they are sufficiently deep so as to accommodate the protrusions 32.
- the bottom of the closures 46a may be flat and yet keep the umbrella ribs closed between the cap 62 and the base member 42.
- Protrusions 58a are also being formed in the bottom of the closures 46a, and are matching the bores 58 made in the rib holders 46 of the base part 40, so as to facilitate connecting the cap on top of the base part.
- a gap 44a is formed between each pair of neighboring closures 46a, forming extension to a corresponding gap 44 located between respective pair of neighboring rib holders 46, thus allowing the umbrella ribs to pivot between a fully deployed state and a fully closed state.
- Fig. 10 illustrates an isometric view of the base part 40 illustrated by Fig. 8.
- Fig. 11 illustrates in isometric another embodiment of a two part housing 150 connected on top of umbrella stick 139.
- Cap 162 of the housing 140 is secured to base part 140, and eight umbrella ribs 131 are pivotally connected between the cap and the base part. Due to gaps 144 formed between pairs of neighboring rib holders 146, the umbrella ribs may be folded to lay juxtaposed the stick 139 when the umbrella is closed.
- the diameter of the closed umbrella is determined by the diameter of the housing at its widest portion 180.
- the ribs 131 do not significantly influence the diameter of the closed umbrella, since they are accommodated within the gaps.
- the cap 162 has integral threaded bolt protruding upwardly, useful for mounting a ferrule.
