The field relates to a holder for receiving a pole, such as a volleyball net or outdoor umbrella. The holder can be installed in a swimming pool or an outdoor patio. The holder provides increased stability for the pole such that the pole is not easily dislodged from the holder.
The features and advantages of certain embodiments will be more readily appreciated when considered in conjunction with the accompanying figures. The figures are not to be construed as limiting any of the preferred embodiments.
Many people enjoy outdoor activities such as playing outdoor sports like volleyball or badminton, swimming, and sitting outside. It is often desirable to position one or more outdoor umbrellas for outdoor patios, including patios surrounding a swimming pool. The outdoor umbrellas can provide shade to people on the patio.
Nets are required for some sports such as volleyball and badminton. A pole is an integral part of nets and outdoor umbrellas. For example, a net is secured between two poles; and the material making up an outdoor umbrella is secured to the top of a pole.
Most net poles are simply inserted into the soil. The pole of an outdoor umbrella is also commonly inserted into soil or inserted into a base. Bases for outdoor umbrella poles are generally circular or square in shape and designed to be placed on the surface of the ground or patio. Water volleyball nets for use in a swimming pool are generally strung between two poles, wherein the poles are inserted into two bases located on the patio surface at the perimeter of the swimming pool or the pole bases float in the water.
However, there are several disadvantages to common pole bases. For poles inserted into soil or a traditional base, the pole can easily move in high winds, become angled, and even fall over. Moreover, most bases—especially bases for water volleyball—do not provide sufficient support and stability to the net poles. This lack of support and stability results in undesirable movement of the net and one or both poles being knocked over if the volleyball hits the net with sufficient force.
Thus, there is a need for an improved pole holders that provide sufficient support and stability to the pole such that the pole remains in a fixed position even in high winds or another force applied to the pole.
It has been discovered that a pole holder can include an insert that is embedded in soil or concrete and a base that threadingly connects to the insert. The pole holder provides increased support and stability to the pole such that movement or dislodgement of the pole is greatly diminished or eliminated when the pole is contacted with a force, such as high winds.
According to certain embodiments, a pole holder comprises: an insert, wherein the insert is embedded into soil or concrete; and a base, wherein the base is removably connected to the insert via a threaded connection, wherein a bottom end of the pole is inserted into the base and insert.
According to certain other embodiments, a method for installing a pole holder comprises: embedding an insert into soil or uncured concrete, wherein a top of the insert is +/−1 inch from the surface of the soil or uncured cement; connecting a base to the insert via a threaded connection; inserting a pole into the base and insert after connection of the base to the insert.
It is to be understood that any discussion of any of the components disclosed herein is meant to include the apparatus and method embodiments without the need to repeat information. By way of example, any discussion related to the insert is meant to apply to the apparatus and method embodiments.
Turning to the figures,
The insert 100 has a top 102 and a bottom 103. The height of the insert 100 is the difference between the top 102 and the bottom 103. According to certain embodiments, the height of the insert 100 is selected such that increased support and stability is provided to the pole. By way of example, as the height of the insert 100 increases so does the support and stability of the pole. By way of another example, the height of the insert 100 may be selected based on the height of the pole. According to this example, as the height of the pole increases, the height of the insert 100 may also need to be increased. The height of the insert 100 can range from 4 in to 8 in (10.16 cm to 20.32 cm).
The base 200 has a top 202 and a bottom. The height of the base 200 is the difference between the top 202 and the bottom. According to certain embodiments, the height of the base 200 is selected such that increased support and stability is provided to the pole. By way of example, as the height of the insert 100 decreases the height of the base 200 may need to be increased in order to provide improved support and stability to the pole. The height of the base 200 does not need to be the same as the height of the insert 100. The height of the base 200 can range from 2 in to 3.5 in (5.08 cm to 8.89 cm).
The base 200 is removably connected to the insert 100 via a threaded connection. As can be seen in
The insert 100 includes female threads 104 for receiving the base 200. The female threads 104 are located at the top 102 of the insert 100. The ID of the female threads 104 can be selected such that the male threads 203 can connect the base 200 to the insert 100. The female threads 104 can also taper in a direction away from the top 102 towards the bottom 103. The degree of tapering of the female threads 104 can be selected to match the degree of tapering of the male threads 203. The ID of the female threads 104 can be larger than the ID of the body 101 of the insert 100. In this manner, after the base 200 is threadingly connected to the insert 100, the body 201 of the base 200 and the body 101 of the insert 100 have substantially the same ID.
The base 200 can also include a hole 204 for receiving a thumb screw 205. The hole 204 penetrates through the entire thickness of the body 201 of the base 200. The hole 204 can include female threads for receiving male threads on the thumb screw 205. The height of the male threads are preferably selected such that an end of the thumb screw located opposite of the head of the thumb screw traverses the entire thickness of the body 201 of the base 200 and enters into the void of the body 201 and can abut the outside of the pole. In this manner, after the pole is inserted into the insert 100 and the base 200, the thumb screw 205 can be tightened to provide added support and stability to the pole.
The insert 100 can also contain a hole 107 for receiving a grounding screw 108. This embodiment can be useful when the pole holder is located in water (e.g., a swimming pool). The grounding screw can be used to ground the pool holder against electrical current and protect people or animals against electric shock. The hole 107 and the grounding screw 108 can be configured as discussed above regarding the thumb screw.
The insert 100 is embedded in soil or concrete.
The insert 100, the base 200, and the pole 400 can be made from a variety of materials. The materials can include metals, metal alloys, and hard plastics. As used herein, the term “metal alloy” means a mixture of two or more elements, wherein at least one of the elements is a metal. The other element(s) can be a non-metal or a different metal. The metal or metal alloy can be selected from iron, cast iron, steel, stainless steel, bronze, copper, and brass. The hard plastics can be selected from, for example, polyvinyl chloride (PVC), nylon, or acetal polyoxymethylene resin sold under the tradenames Delrin™ or Delron™.
According to certain embodiments, the pole holder is NEC (National Electrical Code) compliant for grounding water. This embodiment can be useful when the pole holder is located in an area that is in contact with water, for example, in a swimming pool. According to this embodiment and as discussed above, the insert can include the grounding screw 108. According to this embodiment, the base 200 and the insert 100 may be made from a material that allows the pole holder to be certified compliant. By way of example, the base 200 and the insert 100 may be made from stainless steel. Moreover, the dimensions of the insert 100 and the base 200 can be selected such that the pole holder is certified compliant.
Methods include the step of embedding the insert into soil or uncured concrete. The methods can further include causing or allowing the uncured concrete to cure. Curing is the process by which a cement composition such as concrete sets into a hardened substance or solid. The insert can be stabilized while the concrete cures to prevent the insert from moving out of its intended location or orientation. The base can be connected to the insert after the concrete has cured by threading the male threads 203 to the female threads 104. The pole 400 can then be inserted into the base and insert. The optional thumb screw 205 can then be inserted into the hole 107 for additional support and stability.
The methods can further include disconnecting the base 200 from the insert 100 by unscrewing the threaded connection. This can be performed when the pole is not in use or positioned within the pole holder, such as during winter months. In this manner, the base that extends from the surface of concrete or soil does not provide a hazard, such as people tripping over the base. A cap (not shown) can then be placed over the top of the insert 100 after the base 200 is disconnected to prevent water and/or debris from entering into the insert 100 while the pole holder is not being used.
