As illustrated and described, exercise is increased the weight of the dumbbell that thick stick 102 is designed to band selector 110, the length of this selector 110 and perimeter dimension are usually designed to and are gripped by one of user or two hands at exercise period.As discussed herein, selector 110 can be used for selecting weight 104 and be connected to exercise to increase the weight of on thick stick 102.In addition, exercise period selector 110 can by user's handling.Therefore, selector 110 also can be described as handle 110.Selector 110 can comprise weavy grain shape or anti-skidding surface or material, to improve the gripping of exercise period.Although shown embodiment describes the selector 110 performing weight selection and holding function simultaneously, be understandable that, some embodiments of the present invention can comprise the selector and handle that are separated from each other.Therefore, in some embodiments, during use, selector can be used for selecting weight, and the handle separated can be used for gripping exercising apparatus.

Fig. 2 shows the partial exploded view of the first end of exercise weight system 100.As shown in Figure 2, weight installing rack 112A comprises: first and second end cap 114,116; With common first and second weight separator 118A, 118B of coordinating to limit the groove holding weight 104.First and second end cap 114,116 and first and second weight separator 118A, 118B are such as connected to each other by support 120, and are connected on bar 108, substantially to prevent weight 104 from moving along the axis of bar 108.

Exercise increases the weight of thick stick 102 and also comprises mating system 115, and this mating system 115 is designed for optionally and securely weight 104 is connected to exercise increasing the weight of on thick stick 102.Mating system 115 comprises: selector 110; Around collar 122A, 122B, 122C that bar 108 is arranged; With pin 130A, 130B, 130C, 130D.Support 120 is designed for and substantially prevents collar 122A, 122B, 122C from rotating relative to bar 108 or around bar 108.Collar 122A, 122B, 122C are independent tubular element, it is slidably installed around bar 108, and collar 122A, 122B, 122C can be in substantially parallel relationship to or at least partly along the square upward sliding of the longitudinal axis A of bar 108 between released position and bonding station along the length of bar 108 at least in part.When collar 122A, 122B, 122C are positioned at released position, weight 104 can be received by weight installing rack 112A.After one or more weight 104 is received by weight installing rack 112A, collar 122A, 122B, 122C are movable to bonding station so that optionally and securely one or more weight 104 is connected to exercise and increases the weight of on thick stick 102.As below also by discuss, weight installing rack 112A also comprises locking mechanism 124, and this locking mechanism 124 prevents increasing the weight of collar 122A, 122B, 122C when thick stick 102 is taken out from bearing 106 in exercise and unclamping and moving between bonding station.

Equally as shown in Figure 2, bearing 106 comprises groove 126A-E, and groove 126A-E is designed for first and second end cap 114,116 and weight 104 being received and being supported in groove 126A-E.As shown in Figure 3, the size of groove 126A, E and shape are suitable for by the reception at least partially of first and second end cap 114,116 of correspondence in the inner.Similarly, the size of each groove 126B, 126C, 126D and shape are suitable for by the reception at least partially of weight plates 104 in the inner, as shown in Figure 3.Stop pin 128 to extend or near this groove 126E from groove 126E, and this stop pin 128 and locking mechanism 124 jointly coordinate and engage or released position or allow collar 122A, 122B, 122C engaging or moving between disengaging configuration collar 122A, 122B, 122C to be locked in.

Referring now to Fig. 3, which show the cross-sectional view of the first end of exercise weight system 100.As illustrated, selector 110 is mounted to make selector 110 and bar 108 roughly to have axis A that is common or at least general parallel orientation on bar 108.Selector 110 is mounted to selector 110 can be rotated around axis A relative to bar 108 on bar 108.

In an illustrated embodiment, selector 110 extends into and enters weight installing rack 112A at least partly on bar 108, thus collar 122A, 122B, 122C are arranged on selector 110.As seen in figures 2 and 3, sell 130A, 130B, 130C, 130D to extend and close collar 122A, 122B, 122C from selector 110 radial direction.Pin 130A, 130B, 130C, 130D are connected to selector 110 (such as by forming in screwed to selector 110 or with selector 110), and selector 110 is associated with the motion of pin 130A, 130B, 130C, 130D.Especially, when selector 110 rotates around axis A, pin 130A, 130B, 130C, 130D also rotate around axis A.As will be discussed below in greater detail, selector 110 and pin 130A, 130B, 130C, 130D cause collar 122A, 122B, 122C to move between bonding station, to unclamp or to engage one or more weight 104 unclamping with being roughly parallel to axis A around the rotation of axis A.

As shown in Figure 3, the first end cap 114 is fixedly connected to bar 108, and the first end cap 114 is not moved substantially relative to bar 108.Second end cap 116 comprises inner panel 132 and outside plate 134.Inner panel 132 is fixedly attached on the first end cap 114 via support 120, and inner panel 132 is not also moved substantially relative to bar 108.On the contrary, outside plate 134 is installed to or is connected on selector 110, so that by the mobile associated of the movement of outside plate 134 and selector 110.Like this, when selector 110 rotates around axis A, outside plate 134 also rotates around axis A relative to inner panel 132 and bar 108.

Locking mechanism 124 is connected on inner panel 132, can not rotate to make locking mechanism 124 around axis A or relative to bar 108.Locking mechanism 124 comprises the locking piece 136 of movement between locked and unlocked positions.Fig. 3 shows the unlocked position of locking piece 136.Locking mechanism 124 also comprises biasing member 138, such as spring, and locking piece 136 is biased in latched position by it.When locking piece 136 is positioned at latched position, locking piece 136 engages with in the multiple notches 140 in outside plate 134.The joint of locking piece in notch 140 substantially prevent outside plate 134 and selector 110 rotates around axis A relative to bar 108, thus prevent collar 122A-C to move axially along bar 108.Weight 104 can be prevented to be added on bar 108 or from bar 108 remove to the movement limit of collar 122A-C.On the contrary, when exercise increase the weight of thick stick 102 be placed on as shown in Figure 3 in bearing 106 time, stop pin 128 is engaged in locking piece 136 and locking piece 136 is moved to unlocked position from latched position.Under the state that locking piece 136 is positioned at unlocked position, outside plate 134 and selector 110 can rotate around axis A relative to bar 108, and this just allows to make collar 122A-C engage or unclamp weight 104.

Brake 142 is connected to outside plate 134, this brake 142 is such as ball and spring, forced positioning bead, additional mode prepared material (extramoldedmaterial) or other protrusion, and it is extended so that one in the multiple recesses 144 arranged with the outer surface around bar 108 engages by towards bar 108 bias voltage or towards bar 108.When selector 110 and outside plate 134 rotate relative to bar 108, brake 142 moves and engages between recess 144.When user rotates selector 110 around bar 108, brake 142 and recess 144 can be user and provide sense of touch and/or audio feedback.Such as, brake 142 and recess 144 can provide the instruction when combination of weight 104 or weight 104 has engaged with collar 122A, 122B, 122C or unclamped.In addition, the bond strength between brake 142 and recess 144 is also enough to substantially to prevent selector 110 from rotating relative to bar 108 taking exercise between the operating period of increasing the weight of thick stick 102.As discussed above, stop the relative motion between selector 110 and bar 108 can prevent weight 104 from increasing the weight of thick stick 102 from exercise to throw off.

Start now to pay close attention to Fig. 4, which show the perspective view of taking exercise and increasing the weight of the first end of thick stick 102, wherein eliminate some parts of weight installing rack 112A for convenience of explanation.About Fig. 4, eliminate the first end cap 114, weight separator 118A, 118B and support 120.

Each collar 122A, 122B, 122C engage weight 104 at collar composition surface place.Such as, as shown in Figure 6, weight 104 comprises groove 146, and groove 146 can be received in taking exercise the part---such as bar 108 and collar 122A, 122B, 122C---increasing the weight of thick stick 102 wherein.Weight 104 also comprises one or more collar composition surface, such as surperficial 148A, 148B.Collar composition surface 148A, 148B are designed to, when collar 122A, 122B, 122C are positioned at bonding station, engage with at least one in collar 122A, 122B, 122C.As shown in Figure 6, collar composition surface 148A, 148B can extend local between the opposition side of weight 104.Or as shown in Figure 32,34 and 38, collar composition surface 148A, 148B can the whole distance between the opposition side of weight 104 extend.

Return see Fig. 4, it show further other details of collar 122A, 122B, 122C.Collar 122A, 122B, 122C comprise weight composition surface 150,152,154 respectively.Each weight composition surface 150,152,154 is designed to, and engages with collar composition surface 148A, 148B on weight 104 when collar 122A, 122B, 122C are positioned at bonding station.

Each collar 122A, 122B, 122C also comprise one or more cam surface, and it coordinates with pin 130A, 130B, 130C, 130D and to engage with weight 104 collar 122A, 122B, 122C to be moved into or to unclamp.More specifically, collar 122A comprises left and right cam surface 156,158; Collar 122B comprises left and right cam surface 160,162; And collar 122C comprises left and right cam surface 164,166.Pin 130A, 130B, 130C, 130D upwards extend from selector 110 near cam surface 156,158,160,162,164,166 ground.Particularly, sell 130A upwards to extend from selector 110 near cam surface 156 ground; Pin 130B upwards extends from selector 110 near cam surface 158,160 ground, thus makes pin 130B between collar 122A and 122B; Pin 130C upwards extends from selector 110 near cam surface 160,162 ground, thus makes pin 130C between collar 122B and 122C; And pin 130D upwards extends from selector 110 near cam surface 164 ground.

Each cam surface 156,158,160,162,164,166 all has pattern alternately, and engages with at least one in pin 130A, 130B, 130C, 130D.Fig. 5 illustrates an example of the pattern of cam surface 156,158,160,162,164,166.More specifically, Fig. 5 has illustrated collar 122A, 122B, 122C with planar structure, to show each cam surface pattern.

In the following discussion, the title on " right side " and " left side " is used to be to provide described feature along the relative position of bar 108 length direction or the general identifications of moving.Such as, the feature more kept left than another feature is just installed than the left end of further feature closer to bar 108 along bar 108 in the axial direction, and just installs than the right-hand member of further feature closer to bar 108 in the axial direction along bar 108 than the feature that another feature is more kept right.Similarly, a feature---such as collar 122A-C---is mobile to the left or to the right just represents that the length direction along bar 108 moves closer to the left end of bar 108 or right-hand member respectively.

Each cam surface includes one or more high portion and one or more lower curtate.In an illustrated embodiment, high portion be the ratio other parts of cam surface closer to the left side (namely, left end closer to bar 108) a part, lower curtate is the part of ratio other parts closer to the right (that is, closer to the right-hand member of bar 108) for cam surface.Therefore, such as, cam surface 156 comprises high portion 156A, and this high portion 156A is presented axially in than the position of lower curtate 156B closer to bar 108 left end along bar 108.

When selector 110 rotates around bar 108, the pin 130A-D alternately high portion of engages male wheel face 156,158,160,162,164,166 and lower curtate.When pin joint closes the high portion of left side cam surface, collar will be positioned at released position.In contrast, when pin joint closes the lower curtate of left side cam surface, collar will be positioned at bonding station.Similarly, when pin joint closes the lower curtate of the right cam surface, collar will be positioned at bonding station.In contrast, when pin joint closes the high portion of the right cam surface, collar will be positioned at released position.

Fig. 5 shows the pin 130A engaged with the lower curtate 156B of left side cam surface 156 and pin 130B engaged with the lower curtate 158B of the right cam surface 158 by not limiting example.In such an embodiment, collar 122A is moved to the left to bonding station.In other words, in the view of fig. 5, collar 122A is moved to the left along bar 108, engages with weight 104 to make collar 122A.

Contrary with the collar 122A being positioned at bonding station, Fig. 5 shows collar 122B and is arranged in released position.Pin 130B is shown as and engages with the high portion 160A of left side cam surface 160, and sells 130C and be shown as and engage with the high portion 162A of the right cam surface 162.In such an embodiment, collar 122B has moved right along bar 108 and has moved on to released position.In other words, in Figure 5, collar 122B is located so that on bar 108 collar 122B does not engage with weight 104.To be similar to the mode of collar 122A, collar 122C is shown as equally and is in bonding station.That is, sell 130C and 130D and engage lower curtate 164B and 166B respectively, make collar 122C be moved to the left to engage weight 104 along bar 108.

As mentioned, when selector 110 rotates around bar 108, pin 130A-D also rotates around bar 108.Pin 130A-D causes pin 130A-D alternately to engage with the high portion of each cam surface 156,158,160,162,164,166 and lower curtate around the rotation of bar 108, thus collar 122A, 122B, 122C are moved engaging between released position.Rotation due to pin 130A-D causes collar 122A, 122B, 122C axially to move around along bar 108, therefore pin 130A-D can be called cam-follower, can by collar 122A, 122B, 122C and/or cam surface 156,158,160,162,164,166 referred to as cam.Like this, mating system example of the present invention can comprise selector, one or more weight engagement member (for example, such as collar 122A-C) and camming.Camming can comprise one or more cam as described herein and one or more cam-follower.The components all of mating system is the example for making one or more weight engagement member device of movement between the first position and the second position.

Be understandable that, the alternating pattern of the cam surface 156,158,160,162,164,166 shown in figure is just for illustrating.Cam surface 156,158,160,162,164,166 can as required or be expected to arrange, to allow the weight 104 selecting any type.

Referring now to Fig. 7-13, which show another exemplary embodiment according to exercise weight system 200 of the present invention.Because exercise weight system 200 is similar to exercise weight system 100 in many aspects, therefore the exclusive parts of exercise weight system 200, feature and function will be concentrated on to the discussion of exercise weight system 200 below.

As shown in Figure 7, exercise weight system 200 comprises taking exercise and increases the weight of thick stick 202, multiple weight 204 and be designed for keep taking exercise to increase the weight of the bearing 206 of thick stick 202 and/or multiple weight 204.Take exercise and increase the weight of thick stick 202 and comprise and increase the weight of the bar 208 (see Fig. 8) that extends between the end opposite of thick stick 202 taking exercise generally.Selector 210 and weight installing rack 212A, 212B are arranged on bar 208.The same with other selector discussed here, selector 210 can be used as selector installation and the handle of exercise period for gripping simultaneously.In an illustrated embodiment, weight installing rack 212A is arranged on the first end of bar 208, and weight installing rack 212B is arranged on the second end of bar 208, and selector 210 is pivotally arranged on bar 208 between weight installing rack 212A, 212B.Be similar to selector 110, selector 210 can be used for selecting weight 204 and is connected on bar 208 and for gripping exercise at exercise period increasing the weight of thick stick 202.As shown in Figure 7, weight installing rack 212A, 212B are respectively designed for and receive maximum three weights 204.Will be understood that, weight installing rack 212A, 212B can be designed for and receive more or less weight 204.

Discussion below mainly concentrates on the first end of exercise weight system 200, but it equally also can be applicable to its second end.With further reference to Fig. 7, weight installing rack 212A comprises the first end cap 214 and the second end cap 216, and weight separator.First and second end cap 214,216 and weight separator coordinate the groove limited for holding weight 204 jointly.First and second end cap 214,216 and weight separator are such as connected to each other, substantially to prevent weight 204 from moving along the axis of bar 208 by support 218.

As shown in figures 8-13, exercise increases the weight of thick stick 202 and comprises mating system 215, and this mating system 215 is designed for optionally and securely weight 204 is connected to exercise and increases the weight of on thick stick 202.Mating system 215 comprises: selector 210; Around the cam set 220 that bar 208 is arranged; And around collar 222A, 222B, 222C that cam set 220 is arranged.Cam set 220 and selector 210 are integrally formed or are connected to each other, and make the movement of selector 210 that cam set 220 can be made to produce corresponding movement.Such as, when selector 210 rotates around axis A, cam set 220 is also rotated around axis A.

Collar 222A, 222B, 222C are slidably mounted to collar 222A, 222B, 222C can be slided between released position and bonding station along the direction being in substantially parallel relationship to axis A around cam set 220.When collar 222A, 222B, 222C are positioned at released position, weight 204 can be received by weight installing rack 212A.Once one or more weight 204 is received by weight installing rack 212A, collar 222A, 222B, 222C are movable to bonding station so that optionally and securely one or more weight 204 is connected to exercise and increases the weight of on thick stick 202.Therefore, collar 222A, 222B, 222C is the example of weight engagement member.

As shown in Figure 8, cam set 220 comprises at least partly around the cam path 224,226,228 that bar 208 extends.In an illustrated embodiment, cam path 224,226,228 is formed in the outer surface of the sleeve 221 be installed on bar 208.In this embodiment, sleeve 221 is connected on selector 210, the motion of selector 210 with cam path 224,226,228 to be associated.Sleeve 221 and selector 210 can be connected to each other directly, be integrally formed as single parts, or sleeve 221 can all be fixedly mounted on bar 208 their motion to be associated with selector 210.In other embodiments, cam path 224,226,228 is formed directly in the outer surface of bar 208, and in this case, selector 210 is fixedly mounted on bar 208 their motion to be associated.Be similar to cam surface 156,158,160,162,164,166, each cam path 224,226,228 defines and is conducive to the pattern of the high portion replaced that weight 204 engages and lower curtate closer to the left side of weight 204 and the right respectively.

Fig. 9 shows the perspective view of collar 222B.Collar 222B comprises tubular body 230, which defines opening, by this opening accepts bar 208.Cam pin 232 extends in the opening of tubular body 230.When collar 222B is arranged on bar 208 as illustrated in figs. 10 and 12, cam pin 232 is received in cam path 226.Just as previously noted, when selector 210 rotates around axis A, cam set 220 is rotated around axis A.When cam set 220 is rotated around axis A, cam pin 232 is through cam path 226 and move high portion and lower curtate in cam path 226.The movement of cam pin 232 in cam path 226 between high portion and lower curtate causes collar 222B to move between joint and released position.When cam pin 232 is positioned at the high portion of cam path 226, collar 222B is arranged in bonding station.In contrast, when cam pin 232 is positioned at the lower curtate of cam path 226, collar 222B is arranged in released position.In the embodiment shown in fig. 10, collar 222A, 222B, 222C are when moving to left (namely along axis A, towards shown in bar 208 hold) time be arranged in bonding station, when move to right along axis A (that is, towards selector 210) time be arranged in released position.

Collar 222A, 222C are similar or identical with collar 222B, except the length of the tubular body of collar 222A, 222C is different from each other, and are also different from collar 222B.It should be understood, however, that collar 222A, 222B, 222C can be formed as mutually the same.

Collar 222A, 222B, 222C comprise weight composition surface 234,236,238 respectively.Each weight composition surface 234,236,238 stretches out from the tubular body of collar 222A, 222B, 222C, and until at least two kinds of effects.First, as shown in figure 12, weight composition surface 234,236,238 contacts the bottom surface 250 of support 218, this substantially prevents collar 222A, 222B, 222C and rotates around axis A when cam set 220 is rotated around axis A.Secondly, as discussing more concrete below, weight composition surface 234,236,238 is designed to engage with weight 204 when collar 222A, 222B, 222C are positioned at bonding station.

Figure 11 shows the perspective view of weight 204, and it is optionally connected to exercise and increases the weight of on thick stick 202.Weight 204 comprises groove 240, and this groove 240 can be received in taking exercise the part---such as bar 208 and collar 222A, 222B, 222C---increasing the weight of thick stick 202 wherein.Weight 204 also comprises one or more collar composition surface, such as surperficial 242A, 242B.Collar composition surface 242A, 242B are designed to, when collar 222A, 222B, 222C are positioned at bonding station, engage with at least one in collar 222A, 222B, 222C.Exemplarily, when collar 222B moves to bonding station from released position, weight composition surface 236 will move on to below collar composition surface 242A, 242B, thus will engage collar composition surface 242A, 242B when exercise increases the weight of weight composition surface 236 when thick stick 202 is picked up.As shown in figure 11, collar composition surface 242A, 242B can extend local between the opposition side of weight 204.Or collar composition surface 242A, 242B can the whole distance between the opposition side of weight 204 extend.

Weight 204 also comprises the groove 248 be formed in bottom it.Groove 248 is designed to the pin or the tab that receive bearing 206 when weight 204 is placed on bearing 206.Pin or the tab of groove 248 and corresponding bearing 206 can coordinate jointly to be remained by weight 204 substantially vertical when weight 204 is placed on bearing 206.

Figure 12 shows the cross-sectional view that the exercise fitted together with the weight 204 be located thereon increases the weight of the first end of thick stick 204.More specifically, selector 210 and sleeve 221 are arranged on bar 208, and collar 222A, 222B, 222C are arranged on sleeve 221 by the cam pin 244,232,246 extended in cam path 224,226,228.As discussed before, selector 210 causes cam path 224,226,228 to rotate around axis A equally around the rotation of axis A, and this causes again collar 222A, 222B, 222C to move between joint and released position.

Exercise weight system 200 comprises feedback mechanism, for the instruction providing one or more weight 204 to engage or unclamped to user.The brake discussed for exercise weight system 100 before the feedback mechanism of exercise weight system 200 is similar to and recess system.Particularly, the second end cap 216 comprises inner panel 252 and outside plate 254.Inner panel 252 is fixedly connected on the first end cap 214 via support 218, and inner panel 252 is not rotated around axis A substantially.In contrast, outside plate 254 is installed to or is connected on selector 210, so that by the motion associated of the motion of outside plate 254 and selector 210.Like this, when selector 210 rotates around axis A, outside plate 254 also rotates around axis A relative to inner panel 252.

Brake 256 is connected to outside plate 254, this brake 256 is such as ball and spring, forced positioning bead, additional mode prepared material or other protrusion, and it is extended to engage with in the multiple recesses 258 be formed in inner panel 252 surface by towards inner panel 252 bias voltage or towards inner panel 252.When selector 210 and outside plate 254 rotate around axis A, brake 256 moves and engages between recess 258.When user rotates selector 210 around axis A, brake 256 and recess 258 can be user and provide sense of touch and/or audio feedback.Such as, brake 256 and recess 258 can provide the instruction when combination of weight 204 or weight 204 has engaged with collar 222A, 222B, 222C or unclamped.In addition, the bond strength between brake 256 and recess 258 is also enough to substantially to prevent outside plate 254 from rotating relative to inner panel 252 taking exercise between the operating period of increasing the weight of thick stick 202.Relative motion in stoping and between outside plate 252,254 can prevent selector 210 from rotating, and prevents collar 222A, 222B, 222C from moving between joint and released position.

Just as previously noted, each cam path 224,226,228 defines the alternating pattern between high portion and lower curtate, to impel collar 222A, 222B, 222C to move between joint and released position when selector 210 rotates around axis A.Figure 13 shows the plane of cam set 220, to show pattern and the position relative to each other of each cam path 224,226,228.These patterns of cam path 224,226,228 and position relative to each other make it possible to several weight 204 to combine and are optionally connected to exercise and increase the weight of on thick stick 202.

Figure 13 shows four of cam set 220 and illustrates position P1, P2, P3, P4, when it aligns with the cam pin 244,232,246 of collar 222A, 222B, 222C, can be exercise and increases the weight of thick stick 202 and provide four different weight combinations.That is, when cam set 220 around axis A rotate into make in the P1-P4 of position one to align with cam pin 244,232,246 time, each collar 222A, 222B, 222C will move on to joint or released position in.

Such as, as illustrated, when cam set 220 is when axis A rotates thus position P1 aligns with cam pin 244,232,246, the collar 222A relevant to cam pin 244 will be arranged in bonding station, the collar 222B relevant to cam pin 232 will be arranged in released position, and the collar 222C relevant to cam pin 246 will be arranged in bonding station.When collar 222A, 222C are positioned at bonding station, there are two weights 204 will be connected to exercise and increase the weight of on thick stick 202.

When cam set 220 is when axis A rotates thus position P2 aligns with cam pin 244,232,246, collar 222A, 222B, 222C will all move on in released position.As a result, do not have weight 204 to be connected to exercise to increase the weight of on thick stick 202.In contrast, make cam set 220 around axis A rotate thus position P3 align with cam pin 244,232,246, collar 222A, 222B, 222C will be caused all to move on in bonding station, thus joint three weights 204.When cam set 220 is rotated thus position P4 aligns with cam pin 244,232,246, collar 222A, 222B will move on in bonding station, and collar 222C will move on in released position.It should be understood that shown and described position P1-P4 just for example, cam set 220 is also rotatable to be become to be alignd with pin 244,232,246 in other position of cam path 224,226,228, combines to engage other weight 204 various.

As shown in figure 13, brake 256 and recess 258 are positioned to be engaged with each other when the specific part of cam path 224,226,228 aligns with cam pin 244,232,246.Such as, if brake 256 and recess 258 be positioned to cam pin 244,232, in position P1-P4 shown in 246 with Figure 13 one aligns, then brake 256 coupling recess 258.For user provides, one or more weight 204 has been installed to exercise and increases the weight of on thick stick 202 and take exercise to increase the weight of thick stick 202 operable sense of touch or audio feedback joint between brake 256 and recess 258.

Like this, the example of mating system of the present invention comprises one or more collars of selector 210, cam pack 220, such as collar 222A, 222B, 222C and camming.Camming comprises one or more cam, such as cam path 224,226,228, and one or more cam following face, such as cam pin 244,232,246.Comprise pin 244,232,246, collar 222A-C, the mating system components all of cam path 224,226,228 and selector 210 is the examples for making one or more weight engagement member device of movement between the first position and the second position.

Weight installing rack 212A can comprise the locking mechanism similar or identical with foregoing locking mechanism 124, increases the weight of unclamping and moving between bonding station when thick stick 202 moves apart bearing 206 in exercise to prevent collar 222A, 222B, 222C.When exercise increase the weight of thick stick 202 be placed on bearing 206 time, releasably locking mechanism rotates around axis A to allow selector 210 and cam set 220, thus collar 222A, 222B, 222C can unclamp and move between bonding station.Locking mechanism also can be designed to prevent selector 210 and cam set 220 from increasing the weight of to move relative to tempering other parts increasing the weight of thick stick 202 when thick stick 202 moves apart bearing 206 taking exercise, so as to prevent collar 222A, 222B, 222C exercise increase the weight of thick stick 202 not in bearing 206 time move between joint and released position.

Figure 19 shows the perspective view being optionally connected to and tempering the weight 304 increased the weight of on thick stick 302.Weight 304 comprises groove 364, and this groove 364 can temper the part increasing the weight of thick stick 302, and---such as bar 308, weight engagement member 320A, 320B and/or collar 322A, 222B---is received in wherein.Weight 304 also comprises claw groove 366, and it is designed for and receives weight claw 360 at least partially when weight engagement member 320A or 320B is positioned at bonding station.As shown in figure 19, claw groove 366 can extend local between the opposition side of weight 304.Or claw groove 366 can extend between the opposition side of weight 304 in whole distance.

Figure 20 shows the partial cross section view of exercise weight system 300, and which show a weight 304 and engage with weight engagement member 320A, another weight 304 does not then engage with weight engagement member 320B.In an illustrated embodiment, selector 310 rotates around axis A, thus impels collar 322A, 322B to produce corresponding rotation.As illustrated, collar 322A is located so that the brake 362 of weight engagement member 320A engages with the high portion 332 of collar 320A, and the brake 362 of weight engagement member 320B engages with the lower curtate 346 of collar 320B.Because these engage, second end 350 of weight engagement member 320A moves to bonding station, thus engages with the weight 304 on the left side, and second end 350 of weight engagement member 320B is positioned at released position (therefore not engaging with the weight 304 on the right).More specifically, second end 350 of weight engagement member 320A is enough to impel weight claw 360 to engage with the claw groove 366 of left side weight 304 to the right pivotable or bending degree, and second end 350 of weight engagement member 320B is not enough to impel weight claw 360 to engage with the claw groove 366 of the right weight 304 to the right pivotable or bending degree.

As shown in figure 20, when weight engagement member 320A moves to bonding station, biasing member 358 is pressed against the bottom surface 368 of support 318.Biasing member 358 and surface 368 between interaction by weight engagement member 320A towards released position bias voltage.But biasing member 358 and/or surface 368 can be designed to allow weight engagement member 320A to be pivoted to bonding station, as shown in figure 20.Such as, in an illustrated embodiment, surface 368 is made up of elastomeric material (such as, rubber, foam etc.), and when weight engagement member 320A is pivoted to bonding station, this elastomeric material can be subject to biasing member 358 as shown in Figure 20 and compresses.But when brake 362 engages the lower curtate 334 on collar 322A, the elastic nature on surface 368 is by bias voltage or force weight engagement member 320A move or be pivoted to released position.Or surface 368 can be cardinal principle rigidity, and biasing member 358 can be made up of elastomeric material weight engagement member 320A being biased into released position.

As shown in figure 20, exercise weight system 300 comprises feedback mechanism, its instruction providing one or more weight 304 to engage or unclamped to user.The feedback mechanism of exercise weight system 300 is similar to the feedback mechanism of exercise weight system 200.Particularly, the second end cap 316 is fixedly attached on bar 308 and the first end cap 314 via support 318, thus the second end cap 316 does not rotate substantially relative to bar 308.Just as previously noted, selector 310 rotates relative to bar 308 to make weight engagement member 320A, 320B move between joint and released position.Like this, selector 310 rotates relative to the second end cap 316.

Brake 370 is connected on the second end cap 316, this brake 370 is such as ball and spring, forced positioning bead, additional mode prepared material or other protrusion, and it is towards selector 310 bias voltage or extension to engage with in the multiple recesses 372 be arranged in selector 310 surface.When selector 310 rotates around bar 308, brake 370 moves and engages between recess 372.When user rotates selector 310, brake 370 and recess 372 can be user and provide sense of touch and/or audio feedback, thus show that the combination of when weight 304 or weight 304 engages with weight engagement member 320A, 320B or unclamps.In addition, the bond strength between brake 370 and recess 372 is also enough to substantially prevent selector 310 from rotating relative to the second end cap 316 during use exercise increases the weight of thick stick 302, thus prevents weight 304 from increasing the weight of thick stick 302 disengaging at exercise period from exercise.

Just as previously noted, cam surface 330,342 defines the alternating pattern between high portion and lower curtate, and this alternating pattern impels weight engagement member 320A, 320B to move between joint and released position when selector 310 rotates around axis A.These alternating patterns and high portion and the lower curtate relative position on collar 320A, 320B allows multiple weight 304 to combine and is optionally connected to exercise and increases the weight of on thick stick 302.Be understandable that, the alternating pattern of the cam surface 330,342 shown in figure is just for illustrating.Cam surface 330,342 can as required or be expected to arrange, to allow the weight 304 selecting any type.

According to disclosure herein, be understandable that, the parts of mating system 315 are the example for making one or more weight engagement member device of movement between the first position and the second position.

Weight installing rack 312A can comprise the locking mechanism similar or identical with foregoing locking mechanism 124, and it increases the weight of unclamping and moving between bonding station when thick stick 302 moves apart bearing 306 in exercise for preventing weight engagement member 320A, 320.When exercise increase the weight of thick stick 302 be placed on bearing 306 time, releasably locking mechanism rotates to allow selector 310 and collar 322A, 322B, thus weight engagement member 320A, 320 can unclamp and move between bonding station.Locking mechanism also can be designed to prevent selector 310 and collar 322A, 322B from increasing the weight of to move relative to tempering other parts increasing the weight of thick stick 302 when thick stick 302 moves apart bearing 306 taking exercise, thus prevent weight engagement member 320A, 320B exercise increase the weight of thick stick 302 not in bearing 306 time move between joint and released position.

Now notice is turned to Figure 21-23, which show another exemplary embodiment according to exercise weight system 400 of the present invention.Because exercise weight system 400 is similar to exercise weight system 100,200 and 300 in many aspects, therefore the exclusive parts of exercise weight system 400, feature and function will be concentrated on to the discussion of exercise weight system 400 below.

Such as, binary camming can comprise and to be associated with each weight and optionally to engage one or more pairs of weight engagement members of the weight be associated.Binary camming allows these weight engagement members to carry out being combined optionally to engage weight.As an example, when exercise weight system comprises three weights weight engagement member relevant with three or three to relevant weight engagement member, binary camming allows maximum eight kinds of different weight combinations.Like this, the numerous combination adopting this binary camming just can be provided by binary camming and significantly change the weight of exercise weight system.

In some embodiment of mating system described here, the rotary motion of selector is converted to the motion of the linear of weight engagement member or substantial linear by binary camming.That is, when the selector of exercise weight system rotates around the axis of bar, weight engagement member is moved into along this axis at least partly and engages with the weight of various various combination or be separated.In other embodiment of mating system described here, binary camming converts the rotary motion of selector to weight engagement member moving along a direction, and this direction need not along the axis of bar.In fact, when exercise weight system selector around bar axis rotate time, weight engagement member pivotable, rotate or be moved into diametrically closer to or engage further from bar and with the weight of various various combination or be separated.Should be appreciated that, camming can relative compact, thus exercise weight system described here can not be manufactured too huge.

In the embodiment that weight engagement member moves axially along bar, the conversion that the rotary motion of selector is moved to the substantial linear of weight engagement member is by using one or more cam and the one or more cam-followers be connected on selector to realize.Any one in cam or cam-follower all can be connected on selector, thus the rotation of selector can impel cam or cam-follower to rotate equally.The rotation of cam or cam-follower will cause another to move axially.Such as, if cam is rotatably connected on selector, then the rotation of cam will impel the linear or axially-movable of cam-follower.Or if cam-follower is rotatably connected on selector, then the rotation of cam-follower will impel the linear or axially-movable of cam.Linear or the axially-movable of cam or cam surface impels weight engagement member to move into along the direction of substantial linear or axis equally to engage with weight or be separated.Like this, just mating system can be designed so that the simple rotation of selector just can impel weight engage or unclamp.

To be moved into closer to or further from the embodiment of bar, the rotary motion of selector realizes to the conversion of the roughly radial motion of weight engagement member by using one or more cam surface and one or more cam-follower at weight engagement member.Cam surface can be connected on selector, thus the rotation of selector can impel cam surface to rotate equally.The rotation of cam surface will impel cam-follower to move radially.Such as, the rotation of cam surface will impel cam-follower diametrically mobile closer to or further from bar.The radial motion of cam-follower impels weight engagement member to move in roughly radial direction equally to engage with weight or be separated.Like this, just mating system can be designed so that the simple rotation of selector just can impel weight engage or unclamp.

Each weight engagement member comprises weight composition surface or weight claw, and each weight comprises at least one collar composition surface or claw groove.When weight engagement member moves to bonding station, the weight composition surface of weight engagement member or the collar composition surface of weight claw and weight or claw groove engagement.Weight just can be connected on bar by the joint on these surfaces securely.

Mating system can be designed in every way, to make collar move between joint and released position.Such as, mating system can comprise one or more pin extended away from bar radial direction.These pins are connected into and make selector these pins can be impelled also to rotate around bar around the rotation of bar on selector.These pins can be tightened to along the axis of bar and these pins can only be rotated around bar and can not move along the axis of bar.These pins impel pin to engage with the one or more cam surfaces on weight engagement member around the rotation of bar.When pin around bar rotate and engages male wheel face time, the axis forcing weight engagement member along bar is moved.Weight engagement member moves along this of the axis of bar and is engaging the movement between released position corresponding to weight engagement member.

According to another embodiment, mating system comprises one or more cam path, and it is formed around bar and is connected on selector.The rotation that selector and cam path are connected into the axis making selector around bar can impel cam path around the corresponding rotation of axis of bar.Each weight engagement member comprises the pin extended in one of them cam path.When cam path rotates around bar, pin engages with these cam paths and forces weight engagement member to move along the axis of bar.Weight engagement member moves along this of the axis of bar and is engaging the movement between released position corresponding to weight engagement member.

In another embodiment again, mating system comprises one or more collar respectively with cam surface, and these collars are connected into and collar and cam surface when selector rotates around the axis of bar are rotated around the axis of bar on selector.The rotation of collar impels one or more weight engagement member to move between joint and released position.The rotation of collar impels cam surface to engage with the brake on weight engagement member, thus weight engagement member is moved between joint and released position along the axis of bar.

In yet another embodiment, mating system comprises one or more collar with cam surface, and when selector rotates around the axis of bar, collar rotates around the axis of bar.The rotation of collar impels cam surface and the cam-follower on weight engagement member or ridge or clamp to engage, thus make weight engagement member between joint with released position near or move away from bar.

Exercise weight system described here also can comprise locking mechanism, and collar or weight engagement member are locked in joint or released position when using exercise to increase the weight of thick stick by this locking mechanism.Locking mechanism can comprise bias voltage locking piece, and a part for this bias voltage locking piece or permission selector and engaging mechanism is rotated around the axis of bar thus makes weight engagement member rotate at the axis engaging or move or prevent between released position a part for selector and engaging mechanism around bar thus weight engagement member cannot be moved between joint or released position.

Such as, in one embodiment, selector and end cap are linked together, thus selector can impel end cap also to rotate around bar around the rotation of bar.Locking piece is connected in bar, thus locking piece can not rotate relative to bar.When locking piece is biased in latched position, locking piece engages with the recess in end cap, and this rotates around bar by preventing end cap, and prevents selector from rotating around bar by connecting.As mentioned above, the rotation of selector can impel weight engagement member to move between joint or released position.Like this, by stoping selector to rotate around the axis of bar, locking piece just can prevent weight engagement member from moving between joint or released position.

Locking piece is movable to unlocked position, thus rotatable selector moves between joint or released position to make weight engagement member.According to some embodiment, exercise weight system comprise can keep exercise weight system at least partially with the bearing of weight.Stop pin upwards extends from bearing, and it engages with locking piece when exercise weight system is placed on bearing.When stop pin engagement latch, locking piece moves to unlocked position, thus allows selector to rotate to make weight engagement member move between joint or released position.When exercise weight system moves apart bearing, stop pin is engagement latch no longer, and this just allows locking piece to be biased in latched position.Like this, when exercise weight system is placed on bearing, locking mechanism separates pin automatically, and when exercise weight system moves apart bearing, stop pin automatically locks.

According to another embodiment of the invention, exercise weight system can be designed to take exercise for particular type the barbell of---such as crouch and push away exercise---.Such as, tempering the size increasing the weight of the selector of thick stick is can be gripped by isolated two hands.In other embodiments, exercise increases the weight of thick stick deflection or bending to adapt to various weight exercise exercise.In other embodiments, the present invention can adopt the form of the exercise weight systems such as such as leg press machine, Chest press machine, curved act machine, high machine drawing, chest expanding trainer, or is attached in these systems.
