Abstract

A combined free and stack-weight fitness apparatus (101) utilizes a combination of free weights (103A, 103B) and stack-weight assemblies (111A, 111B) to provide multi-mode fitness training. The total training resistance is a combination of free-weight resistance and stack-weight resistance transmitted to the barbell by cables (109A, 109B). A pair of overhead cables (115A, 115B), attached to a barbell (102), provide vertical support until a substantial portion of the weight on the barbell is borne by the operator.

Description

Combination free and stack-weight fitness apparatus

Technical field

The present invention relates to the body-building equipment field, especially utilize the body-building equipment of free pouring weight (free-weights) and stack-weight (stach-weights).

Background technology

Although have various motions and apparatus that exercises one's muscles and activity, yet free pouring weight weight lifting becomes the exercise method that many sportsmen select always.In the weight lifting process, lift free pouring weight and can make motion unfettered, be in close proximity to the utilization of human strength in many amusements and sports.With the mechanical ratio that adopts lever, cam and the resistance parts as spring and hydraulic pressure or pneumatic cylinders, to the repeatability height of selecting at the used weight of free pouring weight weight lifting.And the uniform resistance that free pouring weight provides is not subjected to the influence of machine components and miscellaneous part wearing and tearing.

The shortcoming that the restraint of liberty pouring weight is used is to need one or more monitoring persons, and is especially all the more so under the strength building situation of the strength that will reach the user and the endurance limit.When the user repeats weight lifting continuously, in the time of till he or she can not lift pouring weight again, these training methods are the most effective.If monitoring person timely then safety problem can not occur, because the user may not give rise to this pouring weight on the bracing or strutting arrangement safely.Even if when monitoring person, they also may not recognize unsafe situation, and perhaps they can not react soon and avoid injury to take place.

Another restriction of free weight equipment need be taken time exactly and be added free pouring weight or take off from free pouring weight assembly.In the free weight bar of tradition,, must take off free pouring weight retainer for example clip or clamp from the health both sides in order to add or to take off pouring weight succeeded by reinstalling clip or clamp.

On the other hand, the stack-weight body-building device provides a kind of by extracting or insert the method that a pin changes required pouring weight quantity fast out in the bottom of a required stack-weight.Unless use rope otherwise the freedom of motion of stack-weight apparatus is restricted, overhead support even be not set.

Can be associated with in the free weight equipment that pouring weight is supported the quick attachment of weight that engage with framework or break away from disclosed, be a a progressive step aspect this in conjunction with as a reference US6293892,6379287,6537182.This device also provides self guarding of dumbbell and allows free weight ends to move independently of each other.

Although in above-mentioned patent, proposed improvement, still need to improve and self guard free weight equipment, it fitness training that is provided by this equipment further is provided changes.

Summary of the invention

Therefore an object of the present invention is to provide body-building equipment, thereby enlarged the type of existing fitness training free pouring weight and stack-weight combination.

Another object of the present invention is to reduce to change and the free relevant required time of pouring weight of pouring weight training.

A further object of the present invention is can provide automatic support for the free pouring weight and the stack-weight equipment of combination when free pouring weight is out of hand.

A further object of the present invention provides the equipment of a kind of promotion that a kind of reality can be provided or " suppressing (jamming) " resistance exercise pattern.

A further object of the present invention is the independent fitness training that wide region is provided when being not easy to barbell exercising.

Another purpose of the present invention is to provide backup support for free weight operation.

Another purpose of the present invention provides a kind of reliable and rational flexible fitness equipment of expense.

The combination of free pouring weight of body-building equipment utilization of the present invention and stack-weight increases the flexible of equipment and renders a service.In a preferred embodiment, if the free pouring weight assembly of barbell one class need not or when the user can not keep the grasping barbell, can be by overhead the supporting of rope assembly of barbell both sides.Two auxiliary ropes that are connected to a pair of stack-weight assemblies provide additional drag from a direction, and this direction is determined by the position that is fixed to the adjustable pulley assembly on the device framework.

Usually, this adjustable pulley assembly can be positioned at and make stack-weight cable from position that following and free pouring weight assembly is connected.The drag overall of barbell is making a concerted effort of free pouring weight assembly resistance and stack-weight resistance.The resistance of free pouring weight assembly generally is exactly barbell and any weight that is connected to the free pouring weight of barbell thereof.In another kind of pattern, fixing overhead cable support and also can promote or " inhibitions " class is trained from the combination of the downward rope load of stack-weight cable, in this training, the operator can apply tangible level or near the training strength of level.

Therefore in other type weight training exercises, the location adjustable pulley assembly can make stack-weight cable from the location, top of barbell and fixing, deducts the power of stack-weight assemblies from the power of free pouring weight assembly.Under this pattern, can regulate the downward force that stack-weight makes the free pouring weight of its full remuneration, the result is that the net weight that acts on the barbell is close to " zero ".A kind of like this pattern is of great use in the rehabilitation training for example in special training.And can increase the power of stack-weight greatly, and perhaps reduce free pouring weight greatly, make upward force from stacked pouring weight greater than downward force from free pouring weight.This arrangement causes carrying out " oppositely " training, in this training, and must be facing to downward " drawing " barbell of common gravity direction.

In other purposes, take off stack-weight cable from free pouring weight assembly, make them be used to utilize the independent arm that D ring or dumbbell carry out or the training of shank.This equipment can and be changed the free pouring weight training of carrying out reality under the situation of pouring weight easily in improved security.

Overhead support cables is connected to barbell on the quick conjugative component of weight on each of two support columns.Heavy quick conjugative component utilize a bias voltage to support column on a plurality of holes or a ratchet that the hole engages in the opening.A solenoid engagement pawls that is energized when the user catches grip actuators on the barbell or sensor provides one to break away from biasing force.Break away from biasing force and be not enough to from the hole of support column, regain ratchet, up to the operator discharges mainly (preferably most of) barbell weight (and downward force of stack-weight) by lifting free pouring weight assembly till.An optional mode selection switch on the framework has guaranteed that during promotion or suppression mode or independent operation barbell can keep support from the top and not consider to praise support.

Retainer folder on the barbell can increase or take off free pouring weight.The joint of the pin between a selected pouring weight and an engaging lever has determined to be connected to the quantity of the stack-weight on the stack-weight cable.By motor and driving screw drive the location, alternative adjustable stack-weight support column can provide a kind of method easily, to support all stack-weights and can come fast and easily to make stack-weight to break away from and engage again by taking off and insert pin.On support column by the stop limits of manual or foot-switch operated the motion of heavy quick conjugative component, thereby limit the accessible extreme lower position of barbell.

For the stack-weight training that single armed or leg carry out, the quick separation securing member that following rope is connected to barbell can take off and be fixed to the D ring from D ring or barbell.Be positioned at below the barbell and Height Adjustable adjustable pulley assembly provides one to regulate the device of this stack-weight cable geometry.
