Portable basketball stands

Technical field

The utility model relates to a kind of portable basketball stands.Specifically, the utility model relates to the portable basketball stands that band can be filled out heavy formula base, can fill when filling out weight at base it is moved, and this system be configured with the packing that helps the portable basketball stands building block so that transport in the more flat packing case of the profile of packing into.

Background technology

Along with basketball movement is universal day by day, increasing people buy portable basketball stands and use at home.This kind portable basketball stands comprises a support bar usually at least, and basket ball board and a basket ring are all fixed thereon, so that a basket ring can be suspended in certain altitude place, top, athletic ground.Most of portable basketball stands all still permanently are installed near the ground, family track so far, thereby the track of family can be used as basketball court.Seldom there is family around their family, to have enough places and can be used as a basketball court specially.

In some cases, determine that the position that portable basketball stands permanently is installed all may have some difficulties.For example, in some family, may bring risk to the traffic on the track in that a portable basketball stands permanently is installed near the track, thereby cause personal injury or cause damage vehicle and portable basketball stands.

Sometimes, unique place that portable basketball stands can be installed but is difficult to permanent the installation.For example, ground may be coated with a layer concrete or pitch, therefore, must chisel a hole on the ground during installation, again the hole is repaired after installing portable basketball stands.So red tape may both expensive, and probably makes the track look not attractive in appearance.

The permanent portable basketball stands that is installed in the open air also can be subjected to the influence of other unfavorable conditions.Because they permanently are installed in the open air, among all being exposed to and exposing to wind and rain the common whole year.Often be exposed to and cause portable basketball stands to pass through oxidation under the wind and rain weather wearing and tearing prematurely.In having the portable basketball stands of moving-member, for example can heighten in the support bar and basket ball board of mechanical device or disconnecting type a basket ring in use, too early oxidation can special trouble.Often be exposed to and also may cause these mechanical devices to damage prematurely under the wind and rain weather.

Even in indoor environment, the portable basketball stands of permanent installation also can be subjected to the influence of some unfavorable conditions.For example, a school all can have one usually as multiduty gymnasium.Some portable basketball stands permanently are installed in the gymnasium,, also may be stoped or hinder at least the carrying out of some other activity even install on the wall or on the ceiling.In formal occasion, people may make difficulties to the outward appearance of the portable basketball stands of permanent installation.The position of permanent installation portable basketball stands also may and hinder carrying out of other sports events.

Consider these or other inherent shortcoming of permanent installation portable basketball stands, people have designed some portable basketball stands.In order to make portable basketball stands more effective, must use and enough fill out weight so that when carrying out Basketball Match, employed support bar, basket ball board and a basket ring are maintained on the fixing substantially position.Therefore, some portable design have been used a large amount of weights of filling out, and make portable basketball stands be difficult to especially move, but also may need quite a few people's help could assemble or removal system.In addition, this type of design wants to buy the people that portable basketball stands uses for those in the own home, and the price height must make them not dare to inquire.

Some early stage designs have adopted packaged type to fill out weight, and for example sandbag or metal are filled out weight etc., use for a supporting structure that support bar is fixed on the ground.A major defect using the packaged type of these types to fill out weight will be filled out these weight exactly, and to move to another place from one very heavy.Although it is all more or less freely to adopt the supporting structure of this design and portable basketball stands to move, to fill out weight be not the part nothing the matter yet move these.Some designs wherein reduce to minimum for the quantity of needed packaged type being filled out weight, cause that to fill out the weight volume very big, because they are filled out the effective weight of weight and taked the long lever arm in order to increase packaged type.

For some portable basketball stands, be used for fixing between the support bar of basket ball board and a basket ring and the base and be a fixed inclination, rather than vertical.Usually doing like this is for enough horizontal ranges are provided between base and basket ball board, and base is generally Pyramid, and to all the winds extends from support bar.The base of this Pyramid is bulky, is not easy to carry out reasonable packing in the more flat packing case of single profile so that shipment.Therefore, the packing of transporting this type of portable basketball stands is relative higher with the shipment cost.This expense will be transferred on one's body the consumer.
