DETAILED DESCRIPTION

Various features as well as advantages that characterize the umbrella base and the retention patio leash described herein will be apparent from a reading of the following detailed description and a review of the associated drawings. Additional features are set forth in the description which follows, and in part will be apparent from the description, or may be learned by practice of the technology. The benefits and features of the technology will be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings. It is to be understood that both the foregoing introduction and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.

Throughout this description, references to orientation (e.g., front(ward), rear(ward), top, bottom, back, right, left, upper, lower, etc.) of the umbrella base and the retention patio leash relate to the position when placed on an underlying surface and/or in use on an umbrella are used for ease of description and illustration only. No restriction is intended by use of the terms regardless of how the umbrella base and the retention patio leash are situated on their own.

The umbrella base described herein is used to support an umbrella (e.g., a patio umbrella) in its upright orientation and for typical outdoor use. Generally, the outdoor umbrella is accompanied with outdoor furniture that can undesirably blow away in the wind when not in use. As such, once the outdoor furniture is no longer in use and to reduce or prevent the furniture from blowing away in the wind, the umbrella base includes a plurality of fastener devices that can be extended from the umbrella base and attached to the adjacent outdoor furniture. By attaching the outdoor furniture to the umbrella base, the outdoor furniture is weighed down against the wind. The fastener devices can be used regardless of the umbrella being supported by the umbrella base. By utilizing the umbrella base as a hold down device, additional components of an outdoor furniture set are no longer needed and do not need to be separately stored when no longer in use. Additionally, the umbrella base can be moved and repositioned as required or desired.

FIG.1is a top perspective view of an exemplary umbrella base100.FIG.2is a bottom perspective view of the umbrella base100. Referring concurrently toFIGS.1-2, the umbrella base100includes an elongated receiver102configured to at least partially receive an end of a pole of an umbrella (e.g., umbrella202shown inFIG.9). As such, the umbrella is configured to cantilever from the umbrella base100such that a canopy of the umbrella is supported in the air without tipping over and users can be at least partially underneath. The elongated receiver102has a top end104and an opposite bottom end106(shown inFIG.3). In the example, the elongated receiver102is formed as a tube that is open at both the top and bottom ends104,106. The bottom end106may include threads. In an aspect, the elongated receiver102may be about 12 inches long and 2 inches in diameter.

A securement device108(shown inFIG.9) is disposed proximate the top end104and is utilized to secure the umbrella pole at least partially within the elongated receiver102. In an aspect, the securement device108includes a threaded bolt and a knob110that are mounted at an aperture112defined within the elongated receiver102. The knob110can be rotated so as to move the bolt within the aperture112and engage with the umbrella pole to secure the pole to the elongated receiver102and hold the umbrella upright.

Additionally, the umbrella base100includes a housing114coupled to and at least partially surrounding the elongated receiver102. The housing114enables the umbrella to be supported in a substantially upright position without tipping over. For example, the housing114is weighted so as to support the umbrella. In operation, the umbrella can be inserted at least partially into the umbrella base100so that the umbrella is supported and the canopy can be used to cover and/or shade an area as required or desired. Typically, during windy conditions, the canopy of the umbrella is collapsed and/or the umbrella completely removed from the umbrella base100so that the umbrella is not moved by the wind. The umbrella base100may be weighted and has a low profile that is wind resistant so that the umbrella base100can be left out in windy conditions.

In the example, the housing114has a substantially cylindrical shape with a bottom surface116, a top surface118, and a side wall120extending between the top and bottom surfaces116,118. The bottom surface116is configured to be placed directly on an underlying surface such as a deck, patio, or the like so that the umbrella can be supported thereon. The top end104of the elongated receiver102extends upward from the top surface118, and in an aspect, the elongated receiver102is centered within the housing114. The housing114is enlarged relative to the elongated receiver102so as to restrict or prevent the umbrella from tipping over when supported by the umbrella base100. In an aspect, the exterior dimensions of the housing114may have the side wall120being about 6 inches tall with about a 20 inch outer diameter.

The housing114includes a bottom body122that defines the bottom surface116and a top body124that defines the top surface118and the side wall120. In the example, the bottom body122is configured to be received at least partially within the top body124. The bottom body122and the top body124define an interior cavity126.

In the example, the housing114is configured to be weighted so as to support the umbrella in a cantilever-type position. In an aspect, the interior cavity126of the housing114is configured to receive one or more weights to provide mass to the housing114. For example, the interior cavity126can be filled with water, sand, and/or weighted plates in order to provide mass to the housing114. In this example, the water, sand, and/or plates can be removed to make it easier to move and reposition the umbrella base100. In another aspect, the housing114(e.g., the bottom and top bodies122,124) may be formed from a dense material (e.g., cast iron or the like) in order to add mass to the housing114.

It should be appreciated, thatFIGS.1-2show only one possible example of an umbrella base100, and the umbrella base100can take on a variety of shapes and sizes while still enabling the umbrella base100to function as described herein. For example, the umbrella base100can include wheels (not shown) so that it is easier to move and position the housing114. In another example, the umbrella base100can include one or more handles (not shown). In still another example, the umbrella base100can take the shape of an end table. In yet another example, the elongated receiver102may be off-center relative to the housing114so that the umbrella can be supported and placed against a wall or a railing as required or desired. In other examples, the housing114can be square-shaped, dome-shaped, cross-shaped, or the like.

The umbrella base100also includes a retention system128supported by the housing114. In the example, the retention system128is disposed within the interior cavity126. The retention system128includes one or more fastener devices130that are configured to selectively extend outward from the housing114and releasably attach to outdoor furniture. The fastener device130is any type of connection member that can releasably attach to outdoor furniture. As illustrated, the fastener device130includes a hook. In other examples, the fastener device can include a snap hook, an adjustable strap like a hook and loop fastener, an elastic member, or the like. The fastener device130is configured to attach to a portion of the outdoor furniture such as a leg of a table or chair, an arm rest of a chair, a frame of a table, or any other component of the outdoor furniture as required or desired. By coupling the housing114to the outdoor furniture, the outdoor furniture is weighed down by the housing114, via the retention system128, so that wind and other environmental conditions are restricted or prevented from moving and blowing away the outdoor furniture.

In the example, the retention system128includes a plurality of fastener devices130spaced circumferentially around the side wall120. This configuration enables multiple pieces of outdoor furniture to be attached to the umbrella base100. For example, multiple chairs, multiple tables, or both chairs and tables may be attached to the umbrella base100and weighed down to protect against windy conditions. In other examples, the umbrella base100may be disposed under a table with a portion of the umbrella pole extending from the elongated receiver102and through the table itself. As such, the retention system128can be used to attach to one or more chairs and/or the table so as to weigh down the outdoor furniture. One example of this configuration is described further below and in reference toFIG.9.

The retention system128is disposed at least partially within the housing114so as to reduce the amount of components that project from the housing114. In the example, a plurality of slots132are defined in the side wall120of the housing114that the fastener device130can extend through and project out from the housing114. As such, the fastener devices130are positioned proximate the exterior of the side wall120. The slots132can extend from the bottom surface116towards the top surface118on the side wall120. The top end of the slots132terminate prior to the top surface118while extending all the way through the bottom surface116. In other examples, the slots132can be fully defined by the side wall120and between the top and bottom surfaces118,116as required or desired. In examples, not all slots132may receive a portion of the retention system128.

The retention system128is disposed proximate the top surface118and offset from the underlying surface when the housing114is placed thereon. This location can maintain the operational functionality and the ornamental look of the housing114for supporting an umbrella. Additionally, by locating the fastener devices130above the underlying surface and towards the top surface118, the fastener devices130can attach to the outdoor furniture at a position raised from the underlying surface so as to reduce or prevent the furniture from tipping over during a windy conditions. In other examples, the fastener devices130can extend from the top surface118as required or desired.

FIG.3is an exploded perspective view of the umbrella base100. The bottom body122has a bottom wall134that forms the bottom surface116of the housing114and a bottom side wall136. At the top end of the bottom side wall136, a plurality of slots138are defined and that enable the retention system128to be disposed within the housing114and allow the fastener devices130to extend and retract therefrom. One or more interior struts140are positioned within the bottom body122and against the bottom side wall136. The interior struts140are configured to support an inner body142of the housing114within the bottom body122.

A collar144is coupled to the bottom wall134and is threaded so that the bottom end106of the elongated receiver102is coupled to the bottom body122and extends upward therefrom.

The inner body142is configured to be receive at least partially within the interior cavity126defined within the bottom and top bodies122,124. The inner body142has an inner bottom wall146and an inner side wall148. The inner bottom wall146defines an opening150for the elongated receiver102to extend through. At the top end of the inner side wall148, a plurality of slots152are defined and that enable the retention system128to be disposed within the housing114and allow the fastener devices130to extend and retract therefrom. The inner bottom wall146is configured to support the retention system128in the interior cavity126.

The retention system128is coupled to the inner body142which allows for the retention system128to be easily assembled and positioned within the housing114. The retention system128include a plurality of retractable straps154(shown inFIG.7) with each of the retractable straps154having the fastener device130coupled to a free end. The retractable straps154are housed within a case156that secures to the inner body142(e.g., via fasteners—not shown). The retractable straps154enable the fastener devices130to be positioned at least partially exterior of the side wall120of the top body124and selectively and retractably extend outwards so as to releasably attach to outdoor furniture. The retractable straps154also enable the fastener device130to be automatically retracted towards the housing114upon release from the outdoor furniture.

The top body124includes the side wall120which extends from a top wall158that forms the top surface118of the housing114. The slots132extend upward from the bottom end of the side wall120. An opening160is defined within the top wall158so that the top end104of the elongated receiver102can extend from the top surface118. A gasket162can be used between the top body124and the elongated receiver102to provide an environmental seal at the top surface118and protect the retention system128below.

FIG.4is a cross-sectional perspective view of the umbrella base100taken along line4-4shown inFIG.2.FIG.5is another cross-sectional perspective view of the umbrella base100taken along line5-5shown inFIG.1.FIG.6is another cross-sectional perspective view of the umbrella base100taken along line6-6shown inFIG.1. Starting first withFIG.4, the housing114is formed from multiple components with the bottom body122, the top body124, and the inner body142. The bottom and top bodies122,124define the interior cavity126. The elongated receiver102is supported by the housing114and defines a longitudinal axis164that extends in a substantially vertical direction when the umbrella base100is positioned on the underlying surface.

The inner body142is disposed within the interior cavity126such that the inner bottom wall146of the inner body142is raised above the bottom surface116of the housing114. In the example, the inner body142is supported within the bottom body122with the interior struts140. As such, the height of the interior struts140along the longitudinal axis164defines the position of the inner body142within the interior cavity126. In an example, the height of the interior struts140is about 3 inches. The retention system128is mounted at least partially within the interior cavity126via the inner body142. The inner body142divides the interior cavity126of the housing114into a top cavity166and a bottom cavity168relative to the longitudinal axis164. The retention system128is disposed within the top cavity166, and one or more weights170(illustrated schematically) are disposed within the bottom cavity168. In the example, the top cavity166and the bottom cavity168are discrete from each other so as to separate the retention system128and the weights170. The weights170may include sand, water, weighted plates, or the like.

In the example, the top cavity166has a smaller volume than bottom cavity168so that the umbrella base100can accommodate enough weight to weigh it down. In an aspect, the top cavity166is about ⅔ the volume of the bottom cavity168. By positioning the retention system128above the bottom surface116, the fastener devices130may be more easy to handle and allows for the connection to the outdoor furniture to occur higher up the leg/structure to reduce overturning moment from wind loads. In the example, the fastener devices130are positioned about 4⅜ inches above the bottom surface116.

Turning next toFIG.5, the top cavity166is illustrated. In the example, the top cavity166is disposed in the top half of the interior cavity126(shown inFIG.4). As such, the retention system128disposed in the top half of the housing114. The retention system128includes a plurality of discrete retention devices172. Each retention device172includes the case156that is mounted to the inner bottom wall146of the inner body142. The case156houses the retractable straps154(shown inFIG.7) with the fastener device130coupled to the free end. The fastener device130is accessible from the exterior of the housing114even with the majority of the retention system128be positioned within the housing114. The retractable strap154can be selectively pulled out from the housing114so that the fastener device130can extend and retract relative to the side wall120of the top body124. In the example, the retractable strap154extends through the slot132defined in the side wall120of the top body124, the slot152defined in the inner side wall148of the inner body142, and the slot138defined in the bottom side wall136of the bottom body122. As such, the fastener device130is positioned exterior of the top cavity166and the case156is positioned within the top cavity166.

The retention devices172of the retention system128are circumferentially spaced around the longitudinal axis164(shown inFIG.4) so that the retractable straps154radially extend and retract relative to the longitudinal axis164. As illustrated, there are eight retention devices172, however, any other number of retention devices172can be included as required or desired. Additionally, each retention device172is discrete and independent from each other. As such, each fastener device130can be independently used as required or desired. In other example, the retention devices172may be coupled together within the retention system128so that movement of opposing fastener devices130correspond to one another. In this example, the retention devices172may be integral with one another.

The retention system128includes a plurality of retractable straps154and the straps are discrete from one another. By using individual retractable straps154, the retention system128can be modified as required or desired to the type and configuration of outdoor furniture that is to be attached. As illustrated, the retractable straps154are circumferentially spaced around the elongated receiver102and approximately 45° apart. This configuration can be used to attach to a plurality of different chairs that are around a table, with the umbrella base100below and in the middle of the table. In order to increase or decrease the number of outdoor furniture pieces that can be attached, the retractable straps154can be added or removed as required or desired. In the example, a total of eight retractable straps154are provided. Other numbers and spacings are also contemplated herein, for example, four retention device172and retractable straps154spaced 90° relative to each other. In an aspect, if fewer retention devices172are provided, the housing114may still include a greater number of slots132,138,152for modification later as required or desired.

The case156of the retention device172can include a reel that the retractable strap154is wound about and that enables the fastener device130to automatically retract towards the housing114upon release from the outdoor furniture. The case156can be attached to the inner bottom wall146of the inner body142via one or more fasteners (e.g., screws—not shown). In some examples, the reel can generate a retraction force on the retractable strap154such that tension is always applied on the strap when extended, and thus, tension is applied to the outdoor furniture when coupled thereto to assist in holding down the furniture in windy conditions. As such, when the fastener device130is released in an extended position, the retractable strap154automatically retracts into the case156. In other examples, the reel can include a ratcheting mechanism so that the retractable strap154can be extended and have its extended length maintained. Once the retractable strap154is released from the ratcheting mechanism (e.g., via a pulling motion), the strap can automatically retract. It should be appreciated, that any other reel mechanism for the retractable strap154can be used as required or desired. By having the retention system128disposed within the top cavity166, the umbrella base100can be used to retain outdoor furniture, and also store the retention system128out of the way when the umbrella is in use.

The bottom body122, the top body124, and the inner body142are oriented relative to the longitudinal axis164such that all of the slots132,138, and152align with each other and so that the retractable strap154can extend out of the housing114. The slots in the bottom body122and the inner body142extend from the top of the side walls, while the slots in the top body124extend from the bottom of the side wall. This configuration enables for the retention system128to be accessible, but the top body124still covers the bottom cavity168(shown inFIG.4).

The elongated receiver102extends through the inner bottom wall146of the inner body142such that the elongated receiver102extends through the top cavity166into the bottom cavity168. In the example, the retention system128is spaced apart from the elongated receiver102. In other examples, the retention system128can be additionally or alternatively coupled to the elongated receiver102as required or desired.

Turning next toFIG.6, the bottom cavity168is illustrated. In the example, the bottom body122is positioned relative to the top body124so that the bottom cavity168is formed within the housing114to hold at least one weight. The weight can be water, sand, or the like. The weight may also be solid weight plates or the like. In an aspect, the mass of the weight can be adjustable so that more weight can be used when more outdoor furniture is connected to the umbrella base100. The bottom cavity168is substantially devoid of structure so that the weight can be disposed therein. In examples, the water or sand may be held in bladders or tanks that are positioned within the bottom cavity168. One or more retainers (not shown) may be provided within the bottom cavity168that hold retain the weight components when disposed therein.

The interior struts140are disposed along the perimeter of the bottom side wall136so as to reduce interference with the weights. The interior struts140may be circumferentially spaced around the elongated receiver102. The elongated receiver102extends through the housing114and couples to the collar144mounted to the bottom wall134of the bottom body122. By extending the elongated receiver102to the bottom wall134, cantilevered support for the umbrella pole is increased. At the bottom cavity168, the bottom side wall136of the bottom body122covers the slots132of the side wall120of the top body124so as to enclose the bottom cavity168.

FIG.7is a partial perspective view of the umbrella base100in an extended configuration.FIG.8is a partial perspective view of the umbrella base100in a retracted configuration. Starting first withFIG.7, the retention system128is illustrated in an extended configuration. That is, the retractable strap154is in an extended configuration with the fastener device130being disposed apart from the housing114. In the extended configuration, the fastener device130can be attached to the outdoor furniture so that the umbrella base100is utilized to hold down the outdoor furniture in windy conditions. The retractable strap154extends and retracts from the housing114via the slots132within the side wall120and are flexible so that it is easier to attach the fastener device130to a variety of locations on the outdoor furniture. This flexibility of the retractable straps154can be in the left or right direction or the up and down direction as required or desired. The extension length of the retractable straps154(e.g., a distance that the fastener device130is positioned away from the housing114) is based on the overall length of the strap and the location of the outdoor furniture. In the example, the slots132of the top body124are aligned with the slots of the bottom body (not shown).

A stop shoulder174is disposed at the proximate end of the fastener device130and is configured to prevent the fastener device130from fully retracting into the housing114. The stop shoulder174is shaped and sized to be received at least partially within the slot132and position the fastener device130at the side wall120of the housing114as illustrated inFIG.8. As such, users can more easily reach the fastener device130when attaching it to the outdoor furniture.

Turning toFIG.8, the umbrella base100typically houses the retractable straps154(shown inFIG.7) in a retracted configuration so that the fastener devices130are positioned against the side wall120. In an aspect, one or more recesses may be defined on the side wall120by the slots132and bottom body configuration to further capture the fastener devices130. Because the umbrella base100also supports an umbrella as required or desired and typically around outdoor furniture (e.g., table and/or chairs). This configuration keeps the fastener devices130out of the way so as to reduce people catching their feet on the fastener devices130when using the outdoor furniture.

In the retracted configuration, the fastener device130may be positioned against the housing114and by the slots132of the top body124. In the example, the fastener device130is pivotable relative to the free end of each of the straps so that the fastener device130can lay substantially flat against the side wall120. While the retention system128is illustrated as being a component of an umbrella base100, it should be appreciated that the retention system128can be used with any other weighted structure so as to retain outdoor furniture. For example, the retention system128can be part of an outdoor storage container, an outdoor table, an outdoor cabinet, or the like.

In operation, the housing114is used to support the umbrella in its upright orientation. Once the outdoor furniture that surrounds the umbrella base100is no longer in use and to reduce or prevent the furniture from blowing away in the wind, the fastener devices130can be extended from the umbrella base100and attached to the adjacent outdoor furniture. By attaching the outdoor furniture to the umbrella base100, the outdoor furniture is weighed down against the wind. The fastener devices130can be used regardless of the umbrella being supported by the umbrella base100. By utilizing the umbrella base100as a hold down device, additional components of an outdoor furniture set are no longer needed and do not need to be separately stored when no longer in use. For example, dedicated ties downs attached to the underlying surface or a plurality of bungee cords. Additionally, the umbrella base100can be moved and repositioned as required or desired.

FIG.9is a perspective view of the umbrella base100in use with outdoor furniture200. The umbrella base100includes the elongated receiver102that defines the longitudinal axis164. The elongated receiver102is configured to partially receive an umbrella202, and more specifically, receive a pole204of the umbrella202so as to support the umbrella202along the longitudinal axis164and position a canopy206above an underlying surface208, such as, a patio or a deck. The housing114is positioned on the underlying surface208via the bottom surface. The bottom surface is spaced from the top surface of the housing along the longitudinal axis164, with the side wall of the housing being parallel to the longitudinal axis164. The retractable straps154are configured to extend and retract radially from the longitudinal axis164such that the fastener device130can attach to the outdoor furniture200. As illustrated inFIG.9, the umbrella base100is positioned underneath a table210and the fastener devices130are attached to chairs212and the table210. In this configuration, the chairs212and the table210are weighted down for windy conditions by the umbrella base100so that they will not blow away. It should be appreciated that the umbrella202does not need to be supported by the umbrella base100in order to attach the chairs212and table210thereto. Additionally, outdoor furniture200can include other types of furniture as required or desired. The outdoor furniture200need not include specific attachment points, as the fastener device130is shaped and sized to attach to multiple different locations on the frame.

The retractable straps154are circumferentially spaced around the longitudinal axis164so that outdoor furniture200may be attached from any direction relative to the umbrella base100. The retractable straps154also extend radially relative to the longitudinal axis164. As such, a radial retention force176is being applied via the retractable strap154so as to hold the outdoor furniture200towards the umbrella base100and restrict the outdoor furniture from moving along the underlying surface208in windy conditions. The fastener device130is disposed above the underlying surface208and attaches to the outdoor furniture200at a location above the underlying surface208so as to reduce the outdoor furniture200from tipping over in windy conditions. By using the umbrella base100to hold down outdoor furniture200in windy conditions, loose tie downs like bungee straps do not need to be used and which can get easily lost. Additionally, extra weighted components are not needed for the outdoor furniture200.

In the example, the retention system is disposed at least partially with a cavity formed by the multi-piece housing114. This construction reduces dirt and debris from accumulating at the retention system. In other examples, the bottom surface may include a cavity formed therein that is configured to house the retention system closer to the underlying surface208and as described herein.

FIG.10illustrates a flowchart of an exemplary method300of assembling an umbrella base. The example methods and operations can be implemented or performed by the systems and devices described herein (e.g., umbrella base100). The method300begins with providing an elongated receiver configured to at least partially receive an end of a pole of an umbrella (operation302). A housing is formed (operation304). In an aspect, the housing includes a bottom body defined a bottom surface configured to be placed directly on an underlying surface, a top body defining a top surface and a side wall, and an inner body. Additionally, a retention system is provided (operation306). In an aspect, the retention system includes a plurality of fastener devices adapted to selective and retractably extend.

The elongated receiver is coupled to the bottom body (operation308). For example, one end of the elongated receiver is coupled to a bottom wall of the bottom body via a threaded collar. Additionally, the retention system is coupled to the inner body (operation310). The inner body is then disposed within an interior cavity at least partially formed by the bottom body (operation312), and the bottom body is covered by the top body (operation314). When the bottom body is covered by the top bottom, the elongated receiver at least partially extends from the top surface of the top body and the plurality of fastener devices are disposed on an exterior of the side wall. In some examples, the method may further include disposing one or more weights between the inner body and the bottom body.

The umbrella base described above is used to support a patio umbrella in its upright orientation and selectively retain other outdoor furniture via the retention system. In other examples, a user may wish to continue to use an existing weighted umbrella base while still obtaining the benefits of the retention system described herein. As such, the retention system can be housed in other housing embodiments. For example, the retention patio leash described below has a housing that is configured to be mounted to an umbrella pole while enabling the plurality of fastener devices to be extended and attached to the adjacent outdoor furniture. The retention patio leash housing need not be weighted as the existing umbrella base is used for the hold down weight. As such, the retention patio leash is lighter and easier to move around. Additionally, the retention patio leash housing may mount to other outdoor furniture, and thus, versatility is increased and a patio umbrella is not necessarily needed for use.

FIG.11is a schematic view an exemplary retention patio leash400in use with outdoor furniture402. The outdoor furniture402includes an umbrella404having a pole406supported on an umbrella base408that is sitting on an underlying surface410and a canopy412. The umbrella base408may be positioned underneath a table414having a plurality of chairs416. It is appreciated that outdoor furniture402can include any other types of furniture as required or desired. In the example, the umbrella base408is configured to support the umbrella404in an upright manner and as known to one of ordinary skill in the art. As such, the umbrella base408may be weighted and/or have an increased footprint so as to support the umbrella404in a cantilever type manner.

The retention patio leash400is configured to be coupled to the pole406of the umbrella404and/or the umbrella base408so as to use the existing umbrella base408for weighted support. By coupling the retention patio leash400to the outdoor furniture402, the retention patio leash400can be used with existing outdoor furniture402and existing aesthetics can be retained, and new weighted support members need not be purchased. The retention patio leash400includes a plurality of retractable straps418that are configured to extend and retract radially from a longitudinal axis420such that a fastener device422can attach to the outdoor furniture402and hold down the outdoor furniture from environmental conditions, such as wind.

In the example, the retractable straps418are circumferentially spaced around the longitudinal axis420so that the outdoor furniture402may be attached from any direction relative to the retention patio leash400and the umbrella404. The retractable straps418also extend radially relative to the longitudinal axis420. As such, a radial retention force424is being applied via the retractable strap418so as to hold the outdoor furniture402towards the umbrella base408and restrict the outdoor furniture402from moving along the underlying surface410in windy conditions. The fastener device422is disposed above the underlying surface410and attaches to the outdoor furniture402at a location above the underlying surface410so as to reduce the outdoor furniture402from tipping over in windy conditions. By coupling the retention patio leash400to the umbrella base408to hold down the outdoor furniture402in windy conditions, loose tie downs like bungee straps do not need to be used and which can get easily lost. Additionally, extra weighted components are not needed for the outdoor furniture402.

As illustrated inFIG.11, the chairs416and the table414are weighted down for windy conditions by the umbrella base408via the retention patio leash400so that they will not blow away. The outdoor furniture402need not include specific attachment points, as the fastener device422is shaped and sized to attach to multiple different locations on the frame (e.g., chair leg, table leg, etc.). As described herein, the retention patio leash400is described as being configured to couple to the umbrella404so that the retention patio leash400can utilize an existing umbrella base408as a weighted member and hold down the outdoor furniture402. It should be appreciated that the retention patio leash400can couple to any other weighted member or secured location and be used to hold down the outdoor furniture402. For example, the retention patio leash400may be coupled to a table leg, a fireplace leg, a column for an overhang, etc.

FIG.12is an exploded, perspective view of the retention patio leash400. The retention patio leash400includes a housing426formed from a first body428and a second body430configured to couple together. In an aspect, the first body428is identical to the second body430to facilitate manufacturing efficiencies. In an example, the housing426may be formed from an injection molded plastic based material. Each body428,430has a disc432having a collar434extending from one side. The collar434defines a through opening and is configured to receive the pole from the umbrella and couple thereto. In other examples, the collar434may receive a table leg or the like. An aperture436is defined in the collar434so that a retention screw (e.g., a threaded bolt and knob110shown inFIG.9) can be used to releasably secure the housing426to the outdoor furniture. As such, the housing426can be selectively positioned along the height of the outdoor furniture as required or desired. In an example, the collar434may have an inner diameter of about 2.5 inches and extend away from the disc432about 1 inch.

A flange438extends from the disc432on the opposite side from the collar434and forms a sidewall of the housing426when coupled to the opposing flange. The flange438extends around an outer perimeter of the disc432. In an example, the flange438may have an outer diameter of about 13.5 inches and extend away from the disc432about 0.5 inches. A plurality of recesses440are defined in the flange438and circumferentially spaced therearound. A plurality of channels442are defined on the disc432and on the side that the flange438is on. The channels442are aligned with the recesses440. The disc432can include one or more fastener openings444so that the bodies428,430can be coupled to each other (e.g., via a bolt, not shown).

In operation, when the bodies428,430are coupled to each other, an interior cavity446is defined so as to receive a retention system448supported by the housing426. The retention system448includes one or more fastener devices422that are configured to selectively extend outward from the housing426via the retractable straps418(shown inFIG.1) and releasably attach to outdoor furniture. The fastener device422is any type of connection member that can releasably attach to outdoor furniture. As illustrated, the fastener device422includes a hook. In other examples, the fastener device can include a snap hook, an adjustable strap like a hook and loop fastener, an elastic member, or the like. The fastener device422is configured to attach to a portion of the outdoor furniture such as a leg of a table or chair, an arm rest of a chair, a frame of a table, or any other component of the outdoor furniture as required or desired.

In the example, the retention system448includes a plurality of fastener devices422spaced circumferentially around the flange438. This configuration enables multiple pieces of outdoor furniture to be attached to the housing426. The retention system448include a plurality of retractable straps418with each of the retractable straps418having the fastener device422coupled to a free end. The retractable straps418are housed within a case450that secures to the housing426(e.g., via fasteners—not shown) via a tab451with an aperture. The case450may be disposed within the channels442defined within the interior cavity446. The fastener device422is disposed on the opposite side of the case450from the tab451and so that the radial retention force is transferred through the case450and into the housing426. In the example, the tab451is positioned at a middle height relative to the height of the case450. The case450restricts or prevents dirt and debris from accumulating within the retractable straps418and reduces wear thereof.

In the example, the housing426is configured to support six cases450, although more or less cases450can be used as required or desired. The retractable straps418enable the fastener devices422to be positioned at least partially exterior of the flange438and selectively and retractably extend outwards so as to releasably attach to outdoor furniture. The retractable straps418also enable the fastener device422to be automatically retracted towards the housing426upon release from the outdoor furniture. Additionally, each case450is discrete and independent from each other. As such, each fastener device422can be independently used as required or desired. In other example, portions of the retention system448may be coupled together so that movement of other fastener devices422correspond to one another. The case450, fastener device422, and the retractable straps418may be generally referred to as a retention device452.

The case450of the retention device452can include a reel that the retractable strap418is wound about and that enables the fastener device422to automatically retract towards the housing426upon release from the outdoor furniture. The case450can be attached within the inner cavity via one or more fasteners (e.g., screws—not shown) at the tab451and with one or both of the first and second bodies428,430. In some examples, the reel can generate a retraction force on the retractable strap418such that tension is always applied on the strap when extended, and thus, tension is applied to the outdoor furniture when coupled thereto and assist in holding down the furniture in windy conditions. As such, when the fastener device422is released in an extended position, the retractable strap418automatically retracts into the case450. In other examples, the reel can include a ratcheting mechanism so that the retractable strap418can be extended and have its extended length maintained. Once the retractable strap418is released from the ratcheting mechanism (e.g., via a pulling motion), the strap can automatically retract. It should be appreciated, that any other reel mechanism for the retractable strap418can be used as required or desired.

The retention system448is disposed at least partially within the housing426so as to reduce the number of components that project from the housing426. In the example, the recesses440may not extend the entire height of the flange. In other examples, the recess440may extend all the way to the disc432. By having the housing426couple to existing outdoor furniture for use, when the retention patio leash400is not in use, it can be easily stored away.

In the example, the housing426is configured to not be weighted with excess mass so that the outdoor furniture that the retention patio leash400is coupled to provides the weight to restrict or prevent the outdoor furniture from moving around when connected. In other examples, the interior cavity446of the housing426may be configured to receive one or more weights to provide additional mass to the housing426and for further weight to restrict or prevent the outdoor furniture from moving around. For example, the interior cavity446can be at least partially filled with water, sand, and/or weighted plates in order to provide mass to the housing426. In another aspect, the housing426may be formed from a dense material (e.g., cast iron or the like) in order to add mass to the housing426.

FIG.13is a top perspective view of the housing426of the retention patio leash400(shown inFIG.12).FIG.14is a bottom perspective view of the housing426. Referring concurrently toFIGS.13-14, the housing426is formed by the first body428being coupled to the second body430. The collars434of each body428,430align along the longitudinal axis420(shown inFIG.11) so that a through opening454is defined in the housing426and that is sized and shaped to receive the pole of the umbrella or other outdoor furniture component. In the example, the through opening454is separated and independent from the interior cavity446defined by the discs432and the flanges438.

The flanges438of each body428,430align to form a sidewall456of the housing426and the recesses440open to one another such that a plurality of slots458are defined in the sidewall456. The slots458facilitate the retractable straps418(shown inFIG.11) extending through the sidewall456and enable operation of the retention system448(shown inFIG.12) described herein.

FIG.15is a top view of the housing426.FIG.16is a bottom view of the housing426. Referring concurrently toFIGS.15and16, the collars434define the through opening454so that the housing426can receive and be coupled on a portion of the outdoor furniture. For example, the umbrella pole may be what the housing426is coupled to. The housing426is substantially symmetrical about the two bodies428,430of the housing426. The discs432with the flanges438form a substantially cylindrical shape that forms the interior cavity. The flanges438have an outer diameter460that is larger than an outer diameter462of the collars434. Additionally, the fastener openings444align so that fasteners can be used to secure the first and second bodies428,430together. The fastener openings444are circumferentially spaced and disposed between the collar434and flange438so that connection strength is facilitated.

FIG.17is a side view of the housing426. The centerline of the collars434define the longitudinal axis420. The collar434of the first body428forms a first end464of the housing426while the collar434of the second body430forms a second end466of the housing426. The ends464,466extending along the longitudinal axis420. The discs432and the flanges438of each of the bodies428,430face each other and define the interior cavity446. The discs432and the flanges438define an intermediate disc body468disposed between the first and second ends464,466and with the slots458for the retention system448(shown inFIG.12).

In the example, the collar434has an axial length470from the disc432that is longer than an axial length472of the flange438from the disc432. An axial length474of the sidewall456(e.g., the two flanges438stacked together) may about equal to or larger than the axial length of the collar434. This configuration of the housing426facilitates attaching to the umbrella pole while also facilitating support of the retention system448. By having the collars434elongated securement to the umbrella pole is facilitated while also restricting or preventing tilting of the housing426when in use.

By using two identical bodies428,430manufacturing efficiencies are increased. In other examples, the two bodies428,430may not be the same configuration. For example, the housing may only have one collar434so that one of the discs432can lay flat (e.g., on the ground or against the outdoor furniture). The collar434may be configured to receive a portion of the umbrella base and couple directly thereto. The collar434may be configured to receive a leg of a table or chair. The collar434may be configured to receive an end of a leg of a table or chair and have the housing426be positioned directly on the ground.

It should be appreciated, thatFIGS.13-17show only one possible example of the housing426, and the housing426can take on a variety of shapes and sizes while still enabling the retention patio leash400to function as described herein. For example, the housing426can include one or more handles (not shown). In still another example, the collar434may be off-center relative to the disc432. In other examples, the housing426can be square-shaped, dome-shaped, cross-shaped, or the like. In yet another example, the housing may be split about a transverse plane relative to the outer diameter and the two housing components may couple around a pole or leg of the outdoor furniture so that the housing does not need to slide along the pole or leg.

FIG.18is an interior view andFIG.18Ais a cross-sectional view taken along line18A-18A of one of the housing bodies428,430. Each body is formed from the disc432having an inner surface476and an outer surface478. The flange438extends from an outer perimeter of the inner surface476and includes recesses440. The recesses440are radially aligned with the channels442defined within the inner surface476. The channels442are shaped and seized to at least partially receive the case450of the retention system448(both shown inFIG.12). The channels442are shallow when compared to the flange438and so that the interior cavity formed by the housing is substantially devoid of structure (and thus weight) other than the retention system448. As such, the channels442are recessed less than the thickness of the case450. Proximate each channel442the inner surface476includes a fastener location480configured to enable the case450to couple to one or both of the housing bodies428,430. In an example, the fastener location480may be a hole through the disc432.

A plurality of interior posts482also extend from the inner surface476of the disc. The interior posts482are configured to align with each other when the housing is assembled and allow fasteners to extend therethrough. In an example, the outer surface478of the disc432includes a countersunk bore at the posts482so that the fasteners are recessed within the disc432. The collar434extends from the outer surface478, and in the example, at least a portion of the collar434can also extend from the inner surface476. As such, when the housing426is assembled, the through opening454defined by the collar434is separated from the interior cavity446.

FIG.19is a perspective view of another housing500for the retention patio leash400(shown inFIGS.12-18).FIG.20is a cross-sectional view of the housing500. Referring concurrently toFIGS.19and20, the housing500is configured for use with the retention system448described above, and thus, the retention system will not be described further below. Similar to the housing426described above, the housing500is formed from a two-piece body502,504. The bodies502,504have a collar506, a disc508, and a flange510such that an interior cavity512is formed. In this example, however, an outer surface513of the disc508is free from any holes, bores, fasteners, etc. and is a substantially smooth surface providing enhanced aesthetics.

To facilitate coupling the bodies502,504together, each body includes a plurality of interior posts514extending from an inner surface of the disc508. Some of the posts514may be male posts while other posts514are female posts so that the bodies502,504can be coupled together. In an example, the posts514form a snap or a press fit connection. The male and female posts alternate on the bodies502,504so that the bodies are still identically formed, just rotated relative to one another when secured together.

Additionally, channels516formed on the inner surface of the disc508for the cases of the retention system448are formed with a wall518that projects from the inner surface. By using a small wall, the thickness of the disc508can be maintained thereby increasing strength. A fastener location520for the cases are formed with projections extending from the inner surface. In the example, the fastener location520has a higher height within the interior cavity512than the walls518.

The retention patio leash described above is configured to be coupled to an umbrella pole, although other outdoor furniture components are also contemplated herein. By coupling the retention patio leash directly to the outdoor furniture, the retention patio leash can be used with existing outdoor furniture and existing aesthetics can be retained and new weighted support members need not be purchased. The retention patio leash includes a plurality of retractable straps that are configured to extend and retract so that fasteners can attach to the outdoor furniture and hold down the outdoor furniture from environmental conditions, such as wind.
