Priority is given to U.S. Patent Application No. 62 / 423,708, which is a continuation application and was filed on November 17, 2016, and U.S. Patent Application No. 62 / 377,042, which was filed on August 19, 2016. Alleged, each incorporated herein by reference in its entirety.

The present invention relates to an umbrella, and more particularly to an umbrella designed to resist reversal in adverse conditions including strong winds and others.

As is well known, an umbrella is a tool that protects a user from the weather, especially from precipitation and snowfall or sunlight, and even from the sun. Conventional umbrellas have the following parts: center rods, canopies, ribs, potter's wheels, springs, and ridges. The middle bar is a metal or wooden shaft that runs between the handle of the umbrella at the bottom (or the base in the case of the patio) and the canopy at the top. The canopy is the cloth part of the umbrella that catches rain, wind and sunlight. The ribs give the umbrella its structure and shape. The outer ribs lift the canopy, and the inner ribs (sometimes called bone recipients) act as supports, connecting the outer ribs to the middle rod of the umbrella. The potter's wheel slides up and down the center rod while being connected to the rib / bone, and is responsible for opening and closing the canopy. Many umbrella designs have an upper spring to hold the wheel up when the canopy is open, a bottom spring to hold the wheel down when the canopy is closed, and in some cases foldable. Includes a center ball spring to extend the length of the center rod. Strictly an ornament, the finial (also known as the crest) can be found at the top of the umbrella above the canopy.

The ribs on the umbrella function in a folding structure that supports the canopy cloth of the umbrella. Under normal operating conditions, the force acting on the canopy cloth of the umbrella increases towards peak values when the canopy is fully deployed and when gusts tend to flip the canopy. These forces are transmitted from the canopy to the canopy ribs and can act on the ribs in opposite directions depending on the direction of the wind. Therefore, the ribs must be strong enough to resist the forces that may act on the ribs from either of the two main opposing directions.

The above structure is the most common structure for an umbrella, and it is presumed that the canopy has a downward convex shape. One serious problem with such a design occurs when there is a strong wind or gust, and the strong wind or gust exerts a force on the inner surface of the canopy, causing the canopy to move upward from its normal position. Invert to a convex position.

Umbrellas that address the problem of gusts have proposed one solution to install holes placed inside the canopy, which allows air to flow through the canopy and reduce the full force received by the canopy. However, the holes are not large enough to provide sufficient airflow to significantly reduce the force, and in most situations the canopy still flips. Another solution to this is to add a spring that connects the umbrella post to the tip area. However, this solution also suffers from the fact that these springs can loosen over time or break or become entangled during use.

Therefore, it is an object of the present invention to provide a windproof umbrella that acts to prevent the umbrella from reversing in strong winds.

According to an exemplary embodiment of the invention, the umbrella is slidably arranged around an elongated shaft having a first end and a second end on the opposite side, as well as a shaft length. Includes a potter's wheel that can move along the line. The umbrella has multiple ribs attached to the potter's wheel by multiple main struts that move between the open and closed positions, the ribs are in the open and extended position in the open position, and the ribs are closed in the closed position. It is in the folded position.

According to the present invention, the umbrella has an anti-reverse mechanism formed from a plurality of anti-reverse columns. Each anti-reversal strut is pivotally coupled to an individual main strut and pivotally connected to a floating joint member that is free to move along the length of the rib. In addition, the anti-reverse mechanism is fixedly attached to the ribs and is positioned to limit the degree to which the floating joint member moves along the ribs and prevent each rib from reversing in response to the applied force. Including the stop part.

As discussed herein, the present invention is directed to improvements relating to a number of components of the umbrella, including but not limited to its shaft structure and rib assembly. As discussed herein, the features of the invention can be implemented in both manual and automatic umbrellas. In addition, other features can be implemented in other types of umbrellas. Accordingly, the following studies and figures illustrate exemplary embodiments that implement the teachings of the present invention.

FIG. 1 shows a side view of the umbrella 100 according to an exemplary embodiment of the invention, showing only one assembly for clarity and to simplify the study of the invention. The umbrella 100 comprises a type commonly referred to as a golf umbrella, which is generally known to be an oversized umbrella used to protect a golfer and a golfer's cart from rain. The long shaft of a golf umbrella is usually not foldable. It will be appreciated and understood that the various features of the invention described herein can be implemented in other types of umbrellas in addition to golf umbrellas.

As shown in FIGS. 1 and 14, the umbrella 100 includes a shaft 110 having a first (top) end 112 and a second (bottom) end 114 on the opposite side. The shaft 110 itself can be formed from any number of different components that work together to provide the shaft 110, the shaft 110 shown in FIG. 1 as described herein by the user. Part of a manual umbrella assembly that manually opens and closes the umbrella. A cap or decorative ridge (not shown) is typically provided at the first end 112 to close the shaft 110, and the handle 130 is gripped by the user at the second end 114. Provided.

With reference to FIGS. 14-16, the indicated shaft 110 is formed from a plurality of different shaft portions that are fitted together to form the assembled shaft. More specifically, the shaft 110 can be formed from three different shaft portions, namely a first shaft portion 111, a second shaft portion 113, and a third shaft portion 115. The first shaft portion 111 is attached to the cap / crest at one end and to one end of the second shaft portion 113 at the other end. The second shaft portion 113 is attached to one end of the third shaft portion 115 at the other end. The third shaft portion 115 is attached to the handle 130 at the other end. Therefore, the first shaft portion 111 represents the upper shaft portion, the second shaft portion 113 represents the intermediate shaft portion, and the third shaft portion 115 represents the bottom shaft portion. The dimensions of the individual shaft portions 111, 113, 115 can vary, especially at least one of the length and / or width (eg, diameter). In the embodiments shown, the portions 111, 113, 115 are shown to have the same width, but the intermediate portion 113 has a length longer than the portions 111, 115, and the portions 111, 115 have the same length. ing. For example, the three shaft portions 111, 113, 115 can be 14 mm shaft portions made of carbon.

The shaft portions 111, 113, 115 are connected to each other by using the coupling member 105. One coupling member 105 is mounted between two adjacent shaft portions 111, 113, 115. The coupling member 105 can be considered as a shaft locking member (locking insertion portion) and can be formed from a metal material such as aluminum. The locking member 105 has a first annular ridge (lip) 107 formed along its outer surface and a second annular ridge (lip) formed along its outer surface and separated from the first annular ridge 107. It can be a hollow member (tube) having a lip) 109. Space 108 is formed between ridges 107 and 109. The annular ridges 107, 109 define a stop for each shaft portion. More specifically, the outer diameters of the locking members 105 on the outer sides of the annular ridges 107 and 109 of the shaft portions 111, 113 and 115 so as to form a frictional fit (mechanical fit) between them. The locking member 105 is selected so that it can be inserted into the hollow interior. Since the annular ridges 107 and 109 have diameters larger than the inner diameters of the shaft portions 111, 113 and 115, the locking member 105 cannot be inserted into the respective shaft portions. Instead, these annular ridges 107, 109 act as retaining portions to prevent the locking member 105 from further inserting into the respective shaft portion. When assembling, the surface of the locking member 105 is visible between the two ridges 107 and 109.

The locking member 105 thus provides a rigid coupling member to which the shaft portions 111, 113, 115 are firmly attached to form a fully assembled shaft.

As mentioned above, one of the main components of the umbrella is the potter's wheel 150. The potter's wheel 150 is a part of an umbrella that opens and closes the umbrella 100, and the potter's wheel 150 moves along the shaft 110. The potter's wheel 150 is therefore a hollow member that surrounds the shaft 110, is movable along the shaft 110, and can be locked in one or more different positions. 17A, 17B, 18A and 18B show the potter's wheel 150 in more detail. The wheel 150 is formed from several parts or parts, generally including a cylindrical base 152 and a shaft wheel locking portion 154. The upper 153 of the potter's wheel 150 is configured to receive and securely attach a plurality of struts to move the ribs 200, as discussed below. The upper portion 153 thus includes a plurality of slots 155 formed circumferentially around the strut to receive the strut. The shaft wheel locking portion 154 is arranged between the upper portion 153 and the base portion 152.

The shaft wheel locking portion 154 is designed to selectively lock the wheel 150 to one of a plurality of locking positions along the shaft 110. 18A and 18B are cross-sectional views of the potter's wheel 150. 17A and 17B show the wheel 150 in the unlocked (open) position with respect to the locking member 105, while FIGS. 18A and 18B show the wheel 150 locked in place with respect to the shaft (FIG. 17A and 17B). That is, the potter's wheel 150 at the locking position (locked to the locking member 105) is shown.

The locking member 105 can be in the form of a piece of aluminum (or other material) that provides a recess (space 108) in the potter's wheel 150 for thus connecting to lock in place. be.

The shaft lock locking portion 154 is designed to lock and engage the shaft locking member 105. The shaft lock locking portion 154 is a push / pull type wheel that moves along the shaft. More specifically, the shaft locro locking portion 154 has an elastic locking member (rocro catching portion) 157 that engages and sits in the space 108 formed between the annular ridges 107 and 109. The elastic locking member 157 can include a ring-shaped locking member 157 with inwardly facing lips, which sits in space 108 when the lips are aligned with space 108. Due to the elasticity (bending) of the locking member 157, the locking member 157 can be bent outward so that it can engage with and disengage from the space 108. When the locking member 157 (particularly its lip 159) engages and disengages from the shaft locking member 105, the potter's wheel 150 can move freely along the shaft 110.

When the potter's wheel 150 reaches a certain point during use where it can no longer move vertically upwards, pressure is directed to the potter's wheel 157 and the potter's wheel 157 itself locks into the locking insert 105. .. One advantage of this design is that the diameter of the shaft should usually have to be machined or reduced in some way in order for the potter's wheel to be able to engage the locking mechanism, or outside the shaft itself to create a locking position. The material should have to be added to. However, adding material to the shaft looks bad and also increases the folded diameter of the umbrella.

17A and 17B show the potter's wheel 150 in the unlocked position, where the potter's wheel 150 moves freely along the shaft. At this unlocked position, the potter's wheel capture unit 157 is not dynamically engaged with the space (recess / channel) 108, whereas in FIGS. 18A and 18B, the potter's wheel capture unit 157 is dynamically engaged with the space (recess) 108. Engaged, thereby locking the wheel 150 to the shaft. As described herein, when the potter's wheel 150 is pressed, the potter's wheel 150 reaches a certain point (such as the points shown in FIGS. 17A and 17B) that cannot move further in the vertical direction. .. When a force is continuously applied in the direction perpendicular to the potter's wheel, the force is applied to the potter's wheel catching portion 157, and as a result, the potter's wheel catching portion 157 is deformed inward in the radial direction toward the locking insertion portion 105.

When the user applies a sufficient force to the potter's wheel 150, the potter's wheel catching unit 157 engages with the locking recess 108, which means that the potter's wheel 150 moves freely. It can be engaged and disengaged from the retaining recess 108.

As described herein, the locking member 105 thus places the wheel 150 along the shaft 110 in the desired position, eg, in a fully open position and in a fully closed position as shown herein. It is positioned so that it can be locked to such as.

It will be appreciated that the potter's wheel 150 is merely an example and does not limit the scope of the invention as other potter's wheel structures can be used with the umbrella of the invention.

In order to move the potter's wheel 150 in either direction (up and down) along the shaft 110, the user only needs to apply sufficient force to engage and disengage the locking member 157 from the locking slot (space 108). be.

The umbrella 100 also includes an upper notch 119 which is attached to the shaft 110 and is a ring-shaped member surrounding the shaft 110. The top notch 119 is configured to receive the ribs 200 and thus serves as a mounting point for such ribs. The ribs can be attached to the shaft 110 by fitting into the top notch 119 and then held by wire or other means. The upper notch 119 can be a thin round nylon or plastic piece with teeth around the edges.

As will be appreciated by the description below, each rib 200 is coupled to both the top notch 119 and the wheel 150, resulting in the opening and closing of the rib 200 and the attached canopy (not shown) based on the direction of movement of the wheel 150. do. The connection between the rib 200 and the potter's wheel 150 is made by a support column 300 (main support column). The strut 300 is an elongated structure having a first end 302 and a second end 304 on the opposite side, the first end 302 being pivotally attached to the potter's wheel 150 and a second end 304. Is pivotally attached to the rib 200. The pivotal connection between the stanchions 300 and the wheel 150 and between the stanchions 300 and the ribs 200 can be accomplished with fasteners such as rivets or pins or the like. More specifically, the first strut joint 310 is formed between the strut 300 and the wheel 150 at the first end 302, and the second strut joint 320 is formed between the strut 300 and the rib at the second end 304. It is formed between 200 and 200.

As shown in FIG. 6, the first strut joint 310 is a male end configured to be pivotally attached to the potter's wheel 150 so that the strut 300 can pivot between the open and closed positions. It can be in the form of a joint.

The second strut joint 320 is in the form of a double joint and is best shown in FIGS. 6 and 7A-D. The second strut joint 320 can also be considered as a strut rib joint, with a first end 321 attached to the distal end of the strut 300 and a second end including a pair of spaced finger portions 323. Including the portion 322, the finger portions 323 are parallel to each other, defining an open space 324 between them, through which fasteners or the like can pass to connect the joint to another structure (rib) as discussed below. It has a aligned opening formed therein for the purpose. As shown in FIGS. 7A-D, the second strut joint 320 also includes a joint fitting 315, which can be in the form of blades protruding outward from the body of the joint 310. (That is, the fitting 315 is formed perpendicular to the main body of the fitting 315). The fitting fitting 315 has an opening formed therein so that the fastener can pass through it so that another structure can be pivotally attached to the fitting fitting 315.

The stanchions 300 can be formed from any number of different materials, including metals (eg zinc alloys).

As shown in the figure, the rib 200 is an elongated structure coupled to other components of the umbrella to provide a rib assembly defined by a plurality of ribs 200 that open and close.

Each rib 200 is an elongated flexible structure having a first end (proximal end) 210 and an opposite second end (distal end) 212. The first end 210 is pivotally attached to the upper notch 119, more specifically the first rib joint 220 is provided to the first end 210 and the rib 200 is relative to the upper notch 119. It can be designed to be pivotal. In the embodiments shown, the first rib joint 220 is in the form of a male end joint that is similar in structure to, or can have the same structure, as the first rib joint 310 that is part of the strut assembly. It is possible.

As best shown in FIG. 6, the rib 200 also includes a second rib joint 230 arranged along the length of the rib 200. The second rib joint 230 can be fixedly attached to the rib 200 at its specific location. Thus, the second rib joint 230 can be in the form of a hollow structure that receives the rib 200 so that the second rib joint 230 does not move during use, but rather stays in a fixed location. , Fixed to the rib 200 and attached. The second rib joint 230 has a connecting portion 232 in the form of a blade (protruding portion) extending radially outward from the second rib joint 230. The connecting portion 232 can therefore be formed perpendicular to the body of the second rib joint 230. The connecting portion 232 includes an opening formed through it.

With reference to FIGS. 6 and 7A-D, the connecting portion 232 is sized to be disposed within an open space 234 defined between a pair of separated finger portions 323 of the second strut joint 320. , It is configured to be arranged in the open space 234. When inserted into the open space 234, the opening formed in the coupling 232 is axially positioned with the opening in the finger 323 to allow the fasteners (pins or rivets or wires, etc.) to pass through. Together, the second strut joint 320 is pivotally attached to the rib 200 (thus the strut 300 is pivotally attached to the rib 200).

According to one aspect of the invention, an anti-reversal mechanism (feature) 400 is provided to counteract the reversal force on the umbrella during selective operating conditions, especially during windy or other adverse conditions. Will be done. As is well known to umbrella users, when a gust is directed upwards towards the inside of the umbrella, the pressure exerted by the wind reverses the canopy so that the ribs push the canopy outward. It works counterproductively. The canopy is generally assumed to have a concave shape when inversion occurs, as well as the ribs being forced to pivot in unintended directions, which can cause one or more ribs to break. This makes the umbrella unusable. The umbrella of the present invention has an anti-reverse mechanism 400 made up of several components discussed individually below.

As shown in FIGS. 6 and 8A-C, the anti-reverse mechanism 400 has a first end 412 coupled to the strut 300 and a second end 414 on the opposite side coupled to the rib 200. The anti-reverse support column 410 is provided. More specifically, the first end 412 is coupled to the second strut joint 320 and the second end 414 is coupled to the rib 200. The anti-reverse strut 410 has a first end joint 411 at the first end 412 and a second end joint 413 at the second end 414. The first and second end joints 411 and 413 shown are in the form of female end joints, specifically the first end joint 411 is a pair of open spaces formed between them. It is defined by a finger portion 415 through the gap, and the second end joint 413 is also defined by a finger portion 417 via a pair of gaps having an open space formed between them. The joint fitting 315 (male joint) is received in the open space between the fingers 415 (female joint) of the first end joint 411, whereby the anti-reverse strut 410 is the anti-reversal strut 410. It is coupled to the strut 300 in a manner that allows it to pivot with respect to the 300.

The first and second end joints 411 and 413 can be mechanically fixed to the elongated strut body, or the end joints 411 and 413 can be formed on top of the existing strut material.

The anti-reversal strut 410 can be formed from any number of different materials, including metals and synthetic materials. In one exemplary embodiment, the anti-reversal strut 410 comprises a 6 mm carbon fiber rod.

The anti-reverse function 400 also includes a floating joint 500 that is slidably coupled to the rib 200 and is configured to mesh with the second end joint 413. 8A-D show the floating joint 500. The floating joint 500 has a body 510, the body 510 including a bore 512 formed therein that represents a through hole from one end of the body 510 through the other end. The floating joint 500 also includes a blade-shaped joint connector 520 extending radially outward from the main body 510. The connector 520 can be formed perpendicular to the main body 510. The connector 520 has an opening formed therein. Therefore, the connector 520 represents a male joint.

The anti-reversal strut 410 is coupled to the rib 200 by inserting a connector 510 between the separated finger portions 417 of the second end joint 413. As with other fittings, fasteners 510 or similar can be used to connect the fitting 510 to the finger portion 417.

The rib 200 is received in the bore 512 and passes through the bore 512, and the size (diameter) of the bore 512 and the size (diameter) of the rib 200 are such that the floating joint 500 is longitudinally along the length of the rib 200. It is selected so that it can move freely. This allows the floating joint 500 to be a joint that allows the rib 200 to move freely up (towards the upper notch 119) and down (towards the tip of the rib) when opening and closing the umbrella.

In another embodiment, the floating joint can be a male part that includes a male connector 520, but the floating joint is in the hollow inside the rib 200 (eg, an extruded aluminum rib or a formed steel rib). It will be appreciated that it is positioned inside the rib 200 so that it can move freely. Therefore, the rib 200 can have a linear slot formed therein, and the connector 520 passes through the linear slot. The operation of the floating joint is otherwise the same. In this alternative embodiment, the "floating action" of the floating joint therefore occurs inside the rib 200 as opposed to outside the rib 200 in the embodiment shown.

With reference to FIGS. 6 and 9A-D, the anti-reverse mechanism 400 also includes a floating joint retaining portion 530 fixed and attached to the rib 200. The floating joint retaining portion 530 is arranged between the floating joint 500 and the second rib joint 230 and stays in a fixed place along the rib 200. The stop 530 includes a bore 532 that extends through it and receives the rib 200. The stop 530 is fixed to the rib 200 using conventional techniques so that the stop 530 is fixed to a particular target location along the length of the rib 200. The stopper 530 can be fixed mechanically or by overmolding, which is the preferred method in this case. The stop portion 530 is constructed so that the stop portion 530 restricts the floating joint 500 from moving in the direction toward the upper notch 119.

It will be appreciated that when the umbrella is in the open position, the floating joint 500 rises along the rib 200 until the floating joint 500 contacts the floating joint stop 530. The floating joint 500, in combination with the floating joint fixing portion 530, prevents the rib 200 from reversing when receiving a strong wind force or the like. Since the rib cannot be bent upward due to the blocking action of the floating joint fixing portion 530, inversion is prevented.

10A-D and 11-13 show details of the tip 600 of the rib 200. The tip 600 comprises a structure that attaches to the distal end of the rib 200. The tip 600 is defined by a hollow body 602 having a bore 603, which receives the distal end of the rib 200 and is secured therein. The tip 600 generally has a triangular wing shape and is defined by first and second wing portions 620, 630 extending outwardly and posteriorly from the body 610. Each wing portion 620, 630 has an inclined front edge 625, 635, respectively, and an inclined trailing edge 627, 637, respectively. In addition, as shown in FIG. 10D, the wings 620, 630 are tilted relative to each other in that the wings 620, 630 are not located on the same plane. The tip 600 is constructed and designed so that the tip 600 is tilted to match the tilt of the canopy when the canopy is in the open position.

11 to 13 show yet another feature of the tip 600 in that the bore 603 of the body 602 includes an urging member 640 such as a spring. The spring 640 is arranged between the distal end of the rib 200 and the stop 605 formed within the body 602. The stop 605 represents the end of the bore 603. The bore 603 is designed so that the distal end of the rib 200 can move so that the rib 200 and the umbrella with respect to it can also move between the open and closed positions. Therefore, the spring 630 stores and releases energy based on a method in which the rib 200 acts on it. FIG. 12 shows the tip assembly in the closed / uncompressed state, while FIG. 13 shows the tip assembly in the open / compressed state. In FIG. 13, the relationship between the canopy and the tip when the umbrella is opened due to the compressed state of the internal spring 640 at the tip.

In an alternative embodiment, the tip can be provided with a male facility (structure) having a protrusion, which is an opening (eg, an opening) formed at the distal end of a rib (eg, an extruded aluminum rib or a formed steel rib). It will be received within the bore). Therefore, the bond is formed by inserting the protruding portion of the tip into the opening (bore) of the rib. Similar to the above embodiment, the urging member such as a spring comes into contact with the protrusion of the tip similarly arranged in the opening (bore) of the rib in the opening (bore) formed in the rib. Can be placed.

FIG. 2 shows the umbrella 100 in the half-open position, especially the single rib assembly, while FIG. 4 shows the umbrella in the fully closed position, especially the single rib assembly.

FIG. 4 shows an umbrella 100 with a plurality of rib assemblies in a fully open position, while FIG. 5 shows an umbrella 100 with a plurality of rib assemblies in a fully closed position.

Each part of the umbrella is necessary for its operation, but the potter's wheel 150 is a part that opens and closes the umbrella. When the wheel 150 is lowered to the end, the stanchion 300 is folded flat with respect to the shaft, the umbrella is "closed", and the waterproof material and ribs are wrapped around the shaft. To open the umbrella, the user slides the wheel 150 to the top to the end. The support column 300 extends, the rib 200 to which the support column 300 is attached rises, and the material (canopy) spreads strongly on the rib 200.

19-21 show an umbrella 700 according to another embodiment. The umbrella 700 is similar to the umbrella 100, so similar elements are similarly numbered. The umbrella 700 includes a shaft 110 and a potter's wheel 150 that slides along the shaft 110. As in the previous embodiment, the connection between the rib 200 and the potter's wheel 150 is made by the support column 300. Unlike the first embodiment, there is no anti-reverse column 400 between the column 300 and the rib 200. Instead, the umbrella 700 of FIGS. 19-21 includes a different anti-reverse strut mechanism 800.

In this embodiment, the anti-reverse strut mechanism 800 includes an anti-reverse strut 810 having a first end 812 and a second end 814 on the opposite side. The first end 812 is operably coupled to a floating notch 815 arranged to move about the shaft 110. More specifically, the floating notch 815 is slidably coupled to the shaft 110 and moves the shaft 110 up and down in much the same manner as the potter's wheel 150. The floating notch 815 is arranged between the potter's wheel 150 and the upper notch 119.

The floating notch 815 can be similar to the upper notch 119 in terms of its structure and can be in the form of a ring-shaped member that is attached to the shaft 110 and surrounds the shaft 110. The floating notch 815 is configured to receive the anti-reverse stanchion 810 and therefore serves as a mounting point for such stanchions. The stanchion 810 can be attached to the shaft 110 by fitting into a floating notch 815 and then held by wire or other means. The floating notch 815 can be a thin round nylon or plastic piece with teeth around the edges.

The first end 812 of the anti-reversal strut 810 is operably coupled to the floating notch 815 and the second end 814 of the anti-reversal strut 810 is operably coupled to the rib 200.

19-21 show the details of the column 810. The anti-reverse strut 810 is formed from the first and second parallel rods 820, 830. The first end of the first and second parallel rods 820, 830 is coupled to the first joint 840 at the first end 812, the first and second parallel rods 820, 830. The end of 2 is coupled to the second fitting 850 at the second end 814. The first fitting 840 can be one of the male and female fittings and the second fitting 850 can be one of the male and female fittings. For example, the first joint 840 can be in the form of a male joint (twin rod male joint) and the second joint 850 can be in the form of a female joint (twin rod female joint). A male joint (eg, joint 840) is defined by a single protrusion (finger) 841, while a female joint (eg, joint 850) is a pair with a space 845 defined between protrusions 843. It is defined by a separated protrusion (finger) 843.

The first fitting 840 is configured to be pivotally attached to the floating notch 815 and the second fitting 850 is configured to be pivotally attached to the rib 200. With respect to the coupling between the joints 840, the protrusion 841 of the first joint 840 is received in a complementary space (slot) formed in the floating notch 815.

The second fitting 850 is operably coupled to a floating fitting, such as the floating fitting 500. As discussed earlier, the floating joint 500 is slidably coupled to the rib 200 and is configured to mesh with the second joint 850. 8A-D show the floating joint 500. The floating joint 500 is defined by a body 510 that includes a bore 512, the bore 512 being formed therein and representing a through hole that passes from one end of the body 510 to the other. The floating joint 500 also includes a blade-shaped joint connector 520 (FIG. 8A) extending radially outward from the main body 510. The connector 520 can be formed perpendicular to the main body 510. The connector 520 has an opening formed therein. Therefore, the connector 520 represents a male joint.

The anti-reversal strut 810 is coupled to the rib 200 by inserting the connector 520 into the space 845 formed between the separated fingers (protruding portions) 843 of the second end joint 413. As with other fittings, fasteners 520 can be coupled to finger 843 using fasteners or the like.

The rib 200 is received in the bore 512 (FIG. 8A), passes through the bore 512, and the size (diameter) of the bore 512 and the size (diameter) of the rib 200 are such that the floating joint 500 follows the length of the rib 200. It is selected so that it can move freely in the longitudinal direction. This allows the floating joint 500 to be a joint that allows the rib 200 to move freely up (towards the upper notch 119) and down (towards the tip of the rib) when the umbrella opens and closes.

The stanchion 300 passes through an open space formed between the first and second parallel rods 820 and 830 of the anti-reverse stanchion 810. This open space between the rods 820 and 830 extends from the first fitting 840 to the second fitting 850, with the stanchions 300 at all positions of the umbrella from the fully closed position to the fully folded position. Store.

In the first embodiment, the rib 200 of the umbrella 700 includes a floating joint fastening portion 530 fixed and attached to the rib 200. The floating joint retaining portion 530 is arranged between the floating joint 500 and the second rib joint 230 and stays in a fixed place along the rib 200. The stop 530 includes a bore 532 that extends through it and receives the rib 200. The stop 530 is fixed to the rib 200 using conventional techniques so that the stop 530 is fixed to a particular target location along the length of the rib 200. The stopper 530 can be fixed mechanically or by overmolding, which is the preferred method in this case. The stop portion 530 is constructed so that the stop portion 530 restricts the floating joint 500 from moving in the direction toward the upper notch 119. Similar to the first embodiment, the stop portion 530 prevents the rib 200 from being inverted under pressure.

Thus, the anti-reverse mechanism in the umbrella 700 is formed between the floating notch 815 and the floating joint 500, as opposed to the first embodiment in which the anti-reverse mechanism is located between the pivotable strut and the rib. It serves to connect the floating notch 815 to the floating joint 500.

Further, in the male / female type connector described in the present specification, the part described in the present specification may contain the female connector instead of the male connector so as to contain the male connector, and conversely, the female. It will also be appreciated that the parts described herein to contain a connector can be reversed in that they can instead contain a male connector. For example, the floating joint 500 is shown with a male connector 520, whereas the floating joint 500 instead has a pair of separated fingers (flange) defining a space (female connector) between them. Can be formed into. Therefore, the distal end of the anti-reversal strut should be formed to have a male joint as opposed to the female joint shown. The coupling is the same in that the male joint is inserted into the space formed within the female joint. Similarly, the properties of other fittings, such as fittings between struts and fixed fittings (eg fitting 230), can be reversed.

The locking feature of the potter's wheel of the present invention also provides many advantages over conventional designs. Specifically, the locking insert provides a connecting feature between the shaft compartments, which allows a method of locking the wheel in place without adding additional locking features. An additional locking feature should increase the diameter of the potter's wheel, which is not desirable.

22-32D show an umbrella 900 according to another embodiment. Umbrella 900 is similar to other umbrellas, so similar elements are similarly numbered. The umbrella 900 includes a shaft 110 and a potter's wheel 150 that slides along the shaft 110. There is also an upper notch 910 along the shaft 110, which slides along the shaft 110. The upper notch 910 is located on the potter's wheel 150 and there is a fixed notch, i.e., a compression notch 920, located at the upper end of the shaft 110. Therefore, the upper notch 910 is arranged between the compression notch 920 and the potter's wheel 150.

The compression notch 920 is pivotally connected to the first rib 930 at the first end of the first rib 930. The second end of the first rib 930 is pivotally coupled to the second end of the compression arm 950. The first end of the compression arm 950 is pivotally connected to the upper notch 910. 32A-D show the first rib 930. The first rib 930 is an elongated structure that is essentially asymmetric. The first end of the first rib 930 has a male feature in the form of a single inclined extension (finger) 931 projecting outward from the body 932 of the first rib 930. As shown, the body 932 generally has a U-shaped structure. A through hole is formed through the extension 931. The extension 931 is configured to mesh with a compressible notch 920 (eg, a fastener can extend through a through hole in the extension 931 to connect the two together). At the opposite second end, the first rib 930 has a female feature in the form of a pair of distant arms 933 parallel to each other. As shown in the top view of FIG. 32C, the open space 934 is formed between the two arms 933.

As shown in the side view of FIG. 32B, the extension 931 is tilted downward in the first direction and the two arms 933 are tilted upward in the second direction. Along the two arms 933, there are two attachment points, namely a first attachment point 935 and a second attachment point 936. The second end of the compression arm 950 is pivotally attached to the first rib 930 at the first attachment point 935 (eg, by using fasteners or the like).

As best shown in FIGS. 23 and 30C, the space 934 formed between the arms 933 allows the first strut 960 to pass through it. The first end of the first strut 960 is pivotally connected to the potter's wheel 150. The second end of the first strut 960 is pivotally connected to the second rib joint 970. The second strut 980 is pivotally connected to the first rib 930 at the first end at the second attachment point 936 (eg, by using fasteners or the like). The second end of the second strut 980 is pivotally connected to the second rib joint 970.

31A-D show the second rib joint 970. The second rib joint 970 is formed from a body 971 which is generally U-shaped. As shown in the figure, the second rib joint 970 is slightly curved along its length. The main body 971 has a first attachment point 972 and a second attachment point 973. The first attachment point 972 is located intermediate to the end of the body 971, while the second attachment point 973 is located at one end of the body 971. The first strut 960 is pivotally attached to the second attachment point 973 by using fasteners or the like. The second strut 980 is pivotally attached to the first attachment 972 at its end. The end of the body 971 opposite the end containing the second attachment point 973 includes a machined opening 974 leading into the hollow interior space. The indicated opening 974 and hollow interior space are D-shaped.

The second rib joint 970 is also attached to the second rib 990 at its first end. More specifically, the first end of the second rib 990 is inserted into the hollow interior space through the opening 974. The second end of the second rib 990 is attached to a tip, such as the tip 1400 described herein. An exemplary tip 1400 is shown in FIGS. 27A-D. The tip 1400 includes a body 1410 having a first open end 1412 and a closed blade-shaped second end 1414.

The length of the first strut 960 is longer than the length of the first rib 930 and the compression arm 950.

Similar to the previous embodiment, the umbrella 800 includes an anti-reverse mechanism 1000. The anti-reverse mechanism 1000 operates in a manner similar to the anti-reverse mechanism described herein.

The anti-reverse mechanism 1000 includes an anti-reverse strut 1010, that is, an anti-reverse sliding joint 1100 and a sliding joint stopper 1200.

As best shown in FIGS. 30A-D, the anti-reverse stanchion 1010 is an elongated structure with a first end 1012 and a second opposite end 1014. 30A-D best show the shape and structure of the anti-reverse column 1010. In some respects, the anti-reversal stanchion 1010 resembles a bone. As shown in the figure, the anti-reverse column 1010 is not symmetrical and instead has a central inflection point 1011 which extends to the first end 1012 and is the first end. A first strut portion 1020 ending at portion 1012 and a second strut portion 1030 extending to the second end portion 1014 and ending at the second end portion 1014 are defined. As described in more detail herein, from the end view (FIG. 30D), the anti-reverse stanchions 1010 are generally H due to the curvature incorporated into the first and second stanchions 1020 and 1030, respectively. Make a letter.

As can be seen from the side view of FIG. 30B, the anti-reverse column 1010 is defined by a first surface 1013 and a second surface 1015 on the opposite side. As can be seen from the figure and as described in more detail below, the first strut portion 1020 has a concave shape along the first surface 1013 and a convex shape along the second surface 1015. On the contrary, the second support column portion 1030 has a convex shape along the first surface 1013 and a concave shape along the second surface 1015.

As can be seen from the plan view of FIG. 30C, each of the first end 1012 and the second end 1014 has a U-shaped notch (opening) 1040 formed therein. The formation of the U-shaped notch 1040 defines the first and second finger extensions 1050, 1052 that are separated and parallel to each other. The open ends of the first and second finger extensions 1050, 1052 receive fasteners or the like to connect the anti-reverse stanchions 1010 to another structure, as described herein. It has an axially aligned opening 1060 formed therein.

As best shown in the perspective view of FIG. 30A, each recess of the first and second strut portions 1020 and 1030 defines a groove 1018 defined by a pair of opposing upright side walls 1019. .. Due to the shape of the anti-reverse stanchion 1010, the depth of the groove formed along the first surface 1013 of the first stanchion 1020, and along the second surface 1015 of the second stanchion 1030. The depth of the formed groove gradually decreases in the direction toward the central inflection point 1011. At the central inflection point 1011 the first and second surfaces 1013 and 1015 move between the concave groove at one end and the convex surface at the other end, respectively.

The contour of the upright side wall 1019 is the same as the contour of the second strut 1030 and the contour of the first strut 1020. In other words, the height of the upright side wall 1019 is the same for the two stanchions 1020 and 1030, but faces in opposite directions as described herein.

The first strut portion 1020 is attached to the second strut 980. More specifically, the AIS (anti-inversion strut) joint 1070 is provided along the location of the second strut 980 and is configured to connect to the first strut portion 1020. In particular, the AIS fitting 1070 can have a protrusion or flange (flag portion) that is inserted into the space 1040 between the arms 1050 and 1052. The fastener passes through the opening 1060 and pivotally joins the two together through the opening in the protrusion of the AIS fitting 1070. The AIS fitting 1070 is located in the middle position between the ends of the second strut 980 and can stay in the selected fixation location. As described below, the groove 1018 of the first strut 1020 is sized and shaped to receive the second strut 980 when the umbrella is folded and considered to be in the closed position.

The anti-reverse mechanism 1000 also includes a floating (sliding) joint 1100 that is slidably coupled to the second rib 990 and is configured to mesh with the second strut portion 1030 of the anti-reverse strut 1010. 28A-D show the floating joint 1100, which is configured such that the floating joint 1100 can slide and move along the second rib 990. The floating joint 1100 has a body 1110 including a bore 1112, the bore 1112 is formed therein and represents a through hole that passes from one end of the body 1110 to the other end. The floating joint 1100 also includes a pair of separated blade-shaped joint fittings 1120 extending radially outward from the body 1110. The connector 1120 can be formed perpendicular to the main body 1110. The connector 1120 has an opening formed therein. The connector 1120 therefore represents a male joint and is positioned below the bore 1112 so as not to interfere with it.

The second portion 1030 of the anti-reverse strut 1010 has a joint connector (two blades) 1120 so that the openings formed through the arms 1050 and 1052 of the second strut 1030 are axially aligned. Is inserted inward between the arms 1050 and 1052 of the second strut portion 1030 to connect to the sliding joint 1100. Fasteners or the like can then pass through the holes and attach in between.

As shown in FIG. 24, when the anti-reverse stanchion 1010 is attached to the peripheral components by the method described herein, the convex first surface 1013 and the first stanchion of the second stanchion 1030. The concave first surface 1013 of the portion 1020 faces the second rib 990. Similarly, the concave second surface 1015 of the second strut 1030 and the convex second surface 1015 of the first strut 1020 face the second strut 980.

Therefore, the anti-reverse strut 1010 is coupled to the second rib 990 by being coupled to the sliding joint 1100.

In another embodiment, the floating fitting can be a male part including a male fitting (part 1120), but in the floating fitting, the floating fitting is formed with a second rib 990 (eg, an extruded rib of aluminum or formed). It will be understood that it is positioned inside the second rib 990 so that it can move freely in the hollow inside the steel rib). Therefore, the rib 990 can have a linear slot formed therein, and the connector 1120 passes through the linear slot. The operation of the floating joint is otherwise the same. In this alternative embodiment, the "floating action" of the floating joint therefore occurs inside the second rib 990 as opposed to outside the second rib 990 in the embodiment shown.

With reference to FIGS. 22 and 29A-D, the anti-reverse mechanism 1000 also includes a floating joint stop 1200, which is fixedly attached to the second rib 990 at a selected fixing location. The floating joint retaining portion 1200 is arranged between the floating joint 1100 and the second rib joint 970 and stays in a fixed place along the rib 200. The stop 1200 includes a bore 1210 that extends through it and receives a second rib 990. The stop 1200 is fixed to the second rib 990 using conventional techniques so that the stop 1200 is fixed at a particular target location along the length of the second rib 990. The stop 1200 can be fixed mechanically or by overmolding, which is the preferred method in this case. The stop portion 1200 is constructed so that the stop portion 1200 restricts the floating joint 1100 from moving in the direction toward the second rib joint 970.

It will be appreciated that when the umbrella is in the open position, the floating joint 1100 rises along the second rib 990 until the floating joint 1100 contacts the floating joint retaining portion 1200. The floating joint 1100, in combination with the floating joint fixing portion 1200, prevents the second rib 990 from reversing when receiving a strong wind force or the like. Since the rib cannot be bent upward due to the blocking action of the floating joint fixing portion 1200, inversion is prevented.

As described herein, the shape of the anti-reverse stanchion 1010 is designed to assist in folding the umbrella into a small occupied area (ie, thin contour) as shown in FIG. More specifically, and as best shown in FIG. 25, the anti-reverse stanchion 1010 is such that when the umbrella 900 is folded into its fully folded position, the anti-reverse stanchion 1010 has a second rib 990 and a second. By nesting between the stanchions 980 and the stanchions 980, it is designed to allow smaller assemblies when folded. As shown in FIG. 25, the groove 1018 of the second strut 1030 nests the distal end (part of between the tip 1400 and the joint stop 1200) of the second rib 990. Similarly, the groove portion 1018 of the first strut portion 1020 receives the second strut 980 in a nested manner. By nesting the second rib 990 and the second strut 980 in this nesting, the entire occupied area of the umbrella 900 at the fully folded position of FIG. 25 is reduced.

Figures 33-38 show the umbrella 1300 according to another embodiment of the present invention. Umbrella 1300 is similar to the other umbrellas disclosed herein, in particular including floating joint arrangements as described herein, and bone-shaped elements as described herein.

Umbrella 1300 includes a shaft 1310 with a handle 1312. The umbrella 1300 also includes an upper notch 1320 located at one end of the shaft 1310 and a slidable potter's wheel 1330. Figures 33-35 show one rib assembly for simplicity.

The upper notch 1320 is configured to receive the ribs 1400 and thus serves as a mounting point for such ribs. The rib 1400 can be attached to the shaft 1310 by fitting into the top notch 1320 and then held by wire or other means. The upper notch 1320 can be a thin round nylon or plastic piece with teeth around the edges.

As will be appreciated by the description below, each rib 1600 is coupled to both the top notch 1320 and the wheel 1330, resulting in the opening and closing of the rib 1600 and the attached canopy (not shown) based on the direction of movement of the wheel 1330. do. The connection between the rib 1600 and the potter's wheel 1330 is made by a strut 1500 (main strut). The strut 1500 is an elongated structure having a first end 1502 and a second opposite end 1504, the first end 1502 being pivotally attached to the potter's wheel 1330 and the second end 1504. Is pivotally attached to the rib 1600. The pivotal connection between the stanchions 1500 and the wheel 1330 and between the stanchions 1500 and the ribs 1600 can be accomplished with fasteners such as rivets or pins or the like. More specifically, the first strut joint 1510 is formed between the strut 1500 and the locro 1330 at the first end 1502, and the second strut joint 1520 is the strut 1500 and ribs at the second end 1504. It is formed between 1600 and.

The first strut joint 1510 can be in the form of a male end joint configured to be pivotally attached to the potter's wheel 1330 so that the strut 1500 can pivot between the open and closed positions. Is.

The second strut joint 1520 is in the form of a double joint and has the structure shown as the joint 320 in FIGS. 6 and 7A-D. The second strut joint 320 can also be considered as a strut rib joint, with a first end attached to the distal end of the strut 1500 and a second end including a pair of separated fingers. Including, the fingers are parallel to each other, defining an open space between them, in which fasteners or the like can pass to connect the fitting to another structure (rib) as discussed below. It has a formed, aligned opening. Additional details of one second strut joint 1520 are shown in FIGS. 7A-D with respect to the second strut joint 320, the second strut joint 320 can have the same structure as the fitting fitting 1520.

The stanchions 1500 can be formed from any number of different materials, including metals (eg zinc alloys).

As shown in the figure, the rib 1600 is an elongated structure coupled to other components of the umbrella to provide a rib assembly defined by a plurality of ribs 1400 that open and close.

Each rib 1600 is an elongated flexible structure having a first end (proximal end) and an opposite second end (distal end). The first end is pivotally attached to the upper notch 1320, more specifically a first rib joint is provided at the first end and the rib 1600 pivots with respect to the upper notch 1320. Can be designed to be able to. In one embodiment, the first rib joint can be in the form of a male end joint that is similar in structure to, or can have the same structure, as the first rib joint that is part of the strut assembly. be.

The rib 1600 also includes a second rib joint 1525 arranged along the length of the rib 1600 (the second rib joint 1525 can be the same as the joint 230). The second rib joint 1525 can be fixedly attached to the rib 1600 at its particular location. Thus, the second rib fitting 1525 can be in the form of a hollow structure that receives the rib 1600 so that the second rib fitting 1525 does not move during use, but rather stays in place. , Fixed to rib 1600 and attached. The second rib joint 1525 has a connecting portion 1527 (FIG. 38) in the form of a vane (protruding portion) extending radially outward from the connecting portion 1525. The connecting portion 1527 can therefore be formed perpendicular to the body of the second rib joint 1525. The connecting portion 1527 includes an opening formed through it.

The connecting portion 1527 is sized to be arranged in an open space defined between a pair of separated finger portions of the second strut joint 1520, and is configured to be arranged in the open space. NS. When inserted into the open space, the opening formed in the fitting 1527 is axially aligned with the opening in the finger to allow the fasteners (pins or rivets or wires, etc.) to pass through. Thereby, the second strut joint 1520 is pivotally attached to the rib 1600 (thus the strut 1500 is pivotally attached to the rib 1600).

Similar to the previous embodiments described herein, the umbrella 1300 has an anti-reverse mechanism. The anti-reversal mechanism includes an anti-reversal strut 1010, that is, an anti-reversal sliding joint 1100 and a sliding joint stopper 530.

The anti-reversal stanchions 1010 used in the umbrella 1300 are described in great detail in the upper part of this specification and are shown in many figures including FIGS. 30A-D. Similar to the previous embodiment, one end of the anti-reverse strut 1010 is pivotally coupled to the strut 1500, while the other end is pivotally coupled to the rib 1600 by a sliding joint 1100. As mentioned earlier, and in some respects, the anti-reversal stanchions 1010 resemble bone. As shown in the figure, the anti-reverse column 1010 is not symmetrical and instead has a central inflection point 1011 which extends to the first end and is the first end. A first strut portion 1020 ending with, and a second strut portion 1030 extending to the second end and ending at the second end are defined. As described in more detail herein, from the end view (FIG. 30D), the anti-reverse stanchions 1010 are generally H due to the curvature incorporated into the first and second stanchions 1020 and 1030, respectively. Make a letter.

The first strut portion 1020 is attached to the strut 1500.

The anti-reverse mechanism also includes a floating (sliding) joint 1100 that is slidably coupled to the rib 1600 and is configured to mesh with the second strut portion 1030 of the anti-reverse strut 1010. 28A-D show the floating joint 1100, the connection between the second portion 1030 of the anti-reverse column 1010 and the sliding joint 1100 is described herein.

The anti-reverse mechanism also includes a floating joint stopper 530 fixedly attached to the rib 1600. The floating joint retaining portion 530 is arranged between the floating joint 1100 and the second rib joint 1525 and stays in a fixed place along the rib 1600. The stop 530 includes a bore 532 that extends through it and receives the rib 200. The stop 530 is fixed to the rib 200 using conventional techniques so that the stop 530 is fixed to a particular target location along the length of the rib 200. The stopper 530 can be fixed mechanically or by overmolding, which is the preferred method in this case. The stop portion 530 is constructed so that the stop portion 530 restricts the floating joint 1100 from moving in the direction toward the upper notch 1320.

It will be appreciated that when the umbrella is in the open position, the floating joint 1100 rises along the rib 1600 until the floating joint 1100 contacts the floating joint stop 530. The floating joint 1100, in combination with the floating joint fixing portion 530, prevents the rib 1600 from reversing when receiving a strong wind force or the like. Since the rib cannot be bent upward due to the blocking action of the floating joint fixing portion 530, inversion is prevented.

Umbrella 1300 also includes tips 600 or 1400 described herein and shown in FIGS. 10A-D and 11-13 and 27A-D.

The anti-reverse stanchion 1010 allows a smaller assembly when folded by the anti-reversal stanchion 1010 being nested between the ribs 1600 and the stanchion 1500 when the umbrella 1300 is folded to its fully folded position. Designed to be. The groove of the first strut 1020 receives the distal end of the rib 1400 (a part between the tip 1400 and the joint stopper 530) in a nested manner, and similarly receives the groove of the second strut 1030. Receives the columns 1500 in a nested manner. By nesting the ribs 1400 and the stanchions 1500, the entire occupied area of the umbrella 1300 is reduced at the fully folded position of FIG.

Although the present invention has been described in the context of certain embodiments thereof, the present invention may be practiced in other forms and other materials and structures may be used. The present invention is therefore defined by the enumeration and its equivalents within the scope of the claims attached herein.
