Description
Technical field
The utility model relates to a kind of basketball stands that have the counterweight base.
Background technology
Universal day by day along with basketball movement, increasing people buy basketball stands and use at home.This kind basketball stands comprise a support bar usually at least, and backboard and ring are all fixed thereon, so that ring can be suspended in the certain altitude place of top, athletic ground.Most of basketball stands all still permanently are installed near the ground, family track so far, thereby make 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 basketball stands permanently are installed all may have some difficulties.For example, in some family, may bring risk to the traffic on the track in that basketball stands permanently are installed near the track, cause personal injury or cause damage vehicle and basketball stands.
Sometimes, above-mentioned unique place that basketball stands can be installed is difficult to permanent the installation also.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 basketball stands.So red tape may both expensive, and probably makes the track look not attractive in appearance.
The permanent basketball stands that are 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 basketball stands to pass through oxidation under the wind and rain weather and wearing and tearing prematurely.In having the basketball stands of moving-member, for example can heighten in the support bar and backboard of mechanical device or disconnecting type 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 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 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 basketball stands of permanent installation.The position of permanent installation basketball stands also may hinder carrying out of other sports events.
Consider these or other inherent shortcoming of permanent installation 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, backboard and 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 basketball stands be difficult to especially move, but also may need quite a few people's help to assemble or to remove.In addition, this type of design wants to buy the people that basketball stands use 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 be moved to another place from one, and is very heavy.Although it is all more or less freely to adopt the supporting structure of this design and basketball stands to move, to fill out weight be not the part nothing the matter yet move these.Some designs wherein are in order to reduce to needed quantity of movably filling out weight minimum, cause that to fill out the weight volume very big, because they have taked the long lever arm in order to increase the effective weight of movably filling out weight.
The Water base has been adopted in some designs, attempts to make a kind of consumer and affords, is fit to very much the portable basketball stands that family uses.This basketball stands can be moved into needed position at an easy rate, at there base is full of water then, thereby enough weight is provided, has been enough to when carrying out Basketball Match, employed support bar, backboard and ring be maintained on the fixing substantially position.When wanting to move these basketball stands, the water turned letter is moved again.The topmost advantage of this basketball stands is the utilization to water.Water is very cheap, sufficient, and is easy to use again.
But still there are some shortcomings in this water tank basketball stands, are exactly all must erect basketball stands and move when adorning water and pouring at every turn, and this just needs the cost regular hour, and inconvenient, also waste water very much.And it is in the right direction also will to carry out precautionary measures assurance pouring when water is poured out, guarantees can not cause damage to house or surrounding environment.If water tank can be damaged when the utilization of water tank also had a danger to be exactly water freezing in the water tank or expansion.
For some portable basketball stands, be used for fixing between the support bar of backboard and ring and the base and be a fixed inclination, rather than vertical.Usually do like this be for the support bar of base on it with and backboard between enough horizontal ranges are provided, 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.
And most of basketball stands are designed to be secured on the vertical surface, thereby ring is positioned on the horizontal plane on the athletic ground.Such as great majority can be heightened mechanical device all needs a vertical installed surface, as at United States Patent (USP) 4,781, and the disclosed mechanical device of heightening in 375 and 4,805,904.Certainly, can use crossover sub, but they can exceedingly increase the cost and the complexity of basketball stands.
Along with the development of various basketball stands, sturdy and durable, cheap portable basketball stands has sizable market demand.The consumer is seeking a kind of product of affording and can substituting permanent installation basketball stands.The retailer of basketball stands also seeking a kind of better basketball stands, both had been easy to show with the floor space of minimum, and can have stacked maximum basketball stands stocks again in limited shelf space.For example, highly be in 8 feet the space, it can only stacked 6 degree of depth be 14 inches carton, and the about 8 inches carton of the degree of depth just can be stacked 12, cost of transportation can also be further saved in the saving in this stacking space, because can transport more basketball stands in a truck or box car.
Although developed various portable basketball stands, but also do not have a kind of be can be packaged in the more flat cartons (for this patent application, during a said packaging carton " more flat ", the degree of depth that means this carton is approximately equal to or less than 12 inches greatly).No matter be to fill out heavy formula base or fill out weight support formula base, all require non-flat packing usually.In addition, be with the building block vanning of basketball stands, the dividing plate that often needs millboard or polystyrene foam plastics to make is to prevent that generation is shifted or causes parts damages in transportation.This dividing plate has increased cost, has finally increased consumer's purchasing price, and for consumers, these dividing plates have finally all become rubbish.Usually, this dividing plate all can make the retail cost of basketball stands increase by 5 percentage points.
