As shown in Figure 3, first end cap 114 is fixedly connected to bar 108, and the end cap 114 of winning is not moved with respect to bar 108 basically.Second end cap 116 comprises inner panel 132 and outside plate 134.Inner panel 132 is fixedly attached on first end cap 114 via support 120, makes inner panel 132 also not move basically with respect to bar 108.On the contrary, outside plate 134 is installed to or is connected on the selector 110, so that with the mobile phase connection with selector 110 that moves of outside plate 134.Like this, when selector 110 rotated around axis A, outside plate 134 also rotated around axis A and with respect to inner panel 132 and bar 108.
Locking mechanism 124 is connected on the inner panel 132, so that locking mechanism 124 can not rotate around axis A or with respect to bar 108.Locking mechanism 124 is included in the locking piece 136 that moves between the locked.Fig. 3 shows the unlocked position of locking piece 136.Locking mechanism 124 also comprises biasing member 138, spring for example, and it is biased into locking piece 136 in the latched position.When locking piece 136 was positioned at latched position, one in a plurality of notches 140 in locking piece 136 and the outside plate 134 engaged.The joint of locking piece in notch 140 prevented that basically outside plate 134 and selector 110 from rotating with respect to bar 108 around axis A, thereby prevented that collar 122A-C from moving axially along bar 108.Can prevent weight 104 is added on the bar 108 or from bar 108 to the motion of collar 122A-C restriction and remove.On the contrary, when exercise increased the weight of that thick stick 102 is as shown in Figure 3 to be placed in the bearing 106, stop pin 128 was engaged in locking piece 136 and locking piece 136 is moved to unlocked position from latched position.Be positioned at locking piece 136 under the state of unlocked position, outside plate 134 can rotate with respect to bar 108 around axis A with selector 110, and this just allows to make collar 122A-C to engage or unclamps weight 104.
Brake 142 is connected in outside plate 134; This brake 142 for example is ball and spring, forced positioning bead, additional mode prepared material (extra molded material) or other protrusion, its by towards bar 108 bias voltages or towards bar 108 extend in case with a plurality of recesses 144 that outer surface around bar 108 is provided with in one engage.When selector 110 rotated with respect to bar 108 with outside plate 134, brake 142 moved between recess 144 and engages.When the user rotated selector 110 around bar 108, brake 142 can be the user with recess 144 sense of touch and/or audio feedback is provided.For example, brake 142 and recess 144 combination that weight 104 or weight 104 can the be provided indication that when engaged or unclamped with collar 122A, 122B, 122C.In addition, the bond strength between brake 142 and the recess 144 is enough to also to prevent basically that selector 110 from increasing the weight of in exercise to rotate with respect to bar 108 between operating period of thick stick 102.As discussed above, stop the relative motion between selector 110 and the bar 108 can prevent that weight 104 from increasing the weight of thick stick 102 from exercise and throwing off.
Begin to pay close attention to Fig. 4 now, it has shown the perspective view of tempering first end that increases the weight of thick stick 102, has wherein removed some parts of weight installing rack 112A for the ease of explanation.About Fig. 4, first end cap 114, weight separator 118A, 118B and support 120 have been removed.
Each collar 122A, 122B, 122C engage weight 104 at place, collar composition surface.For example, as shown in Figure 6, weight 104 comprises groove 146, and groove 146 can increase the weight of exercise the part of thick stick 102---for example bar 108 and collar 122A, 122B, 122C---is received in wherein.Weight 104 also comprises one or more collars composition surface, for example surperficial 148A, 148B.Collar composition surface 148A, 148B are designed to as collar 122A, 122B, when 122C is positioned at bonding station, engage with among collar 122A, 122B, the 122C at least one.As shown in Figure 6, collar composition surface 148A, 148B can local extensions between the opposition side of weight 104.Perhaps, like Figure 32, shown in 34 and 38, collar composition surface 148A, 148B can extend on the overall distance between the opposition side of weight 104.
Return referring to Fig. 4, it has further shown 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, when collar 122A, 122B, when 122C is positioned at bonding station with weight 104 on collar composition surface 148A, 148B engage.
Each collar 122A, 122B, 122C also comprise one or more cam surfaces, and it cooperates with pin 130A, 130B, 130C, 130D so that collar 122A, 122B, 122C are moved into and engages with weight 104 or unclamp.More specifically, collar 122A comprises a left side and right cam surface 156,158; Collar 122B comprises a left side and right cam surface 160,162; And collar 122C comprises a left side and right cam surface 164,166. Pin 130A, 130B, 130C, 130D extend upward from selector 110 near cam surface 156,158,160,162,164,166 ground.Particularly, pin 130A extends upward from selector 110 near cam surface 156 ground; Pin 130B extends upward from selector 110 near cam surface 158,160 ground, thereby makes pin 130B between collar 122A and 122B; Pin 130C extends upward from selector 110 near cam surface 160,162 ground, thereby makes pin 130C between collar 122B and 122C; And pin 130D extends upward from selector 110 near cam surface 164 ground.
Each cam surface 156,158,160,162,164,166 all has pattern alternately, and with pin 130A, 130B, 130C, 130D at least one engage.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, so that show each cam surface pattern.
In the discussion below, the title of using " right side " to reach " left side " is to describe characteristic in order to provide along the relative position of bar 108 length directions or the general identifications of moving.For example; The characteristic that more keeps left than another characteristic just along bar 108 install in the axial direction than further feature more near the left end of bar 108, and than the characteristic that another characteristic is more kept right be along bar 108 install in the axial direction than further feature more near the right-hand member of bar 108.Similarly, characteristic---for example collar 122A-C---moves just expression to the left or to the right and moves more near the left end or the right-hand member of bar 108 respectively along the length direction of bar 108.
Each cam surface includes one or more high and one or more lower curtates.In an illustrated embodiment, high portion be cam surface than other part more near the part of the left side (that is) more near the left end of bar 108, lower curtate be cam surface than other part more near the part of the right (that is, more near the right-hand member of bar 108).Therefore, for example, cam surface 156 comprises the high 156A of portion, and this high 156A of portion is presented axially in than lower curtate 156B more near the position of bar 108 left ends along bar 108.
When selector 110 distaffs 108 were rotated, pin 130A-D is the high portion and the lower curtate of engages male wheel face 156,158,160,162,164,166 alternately.When pin joint closes the high portion of left side cam surface, collar will be positioned at the 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 the released position.
Fig. 5 has shown pin 130A that engages with the lower curtate 156B of left side cam surface 156 and the pin 130B that engages with the lower curtate 158B of the right cam surface 158 through non-limiting example.In this structure, collar 122A has been moved to the left bonding station.In other words, in the view of Fig. 5, collar 122A is moved to the left along bar 108, so that collar 122A engages with weight 104.
Opposite with the collar 122A that is positioned at bonding station, Fig. 5 shows that collar 122B is arranged in the released position.Pin 130B is shown as with the high 160A of portion of left side cam surface 160 and engages, and sells 130C and be shown as with the high 162A of portion of the right cam surface 162 and engage.In this structure, collar 122B moves right and moves on to the released position along bar 108.In other words, in Fig. 5, collar 122B is located such 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 the bonding station.That is, pin 130C and 130D 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 distaffs 108 were rotated, pin 130A-D also distaff 108 rotated.The rotation of pin 130A-D distaff 108 causes pin 130A-D alternately to engage with the high portion and the lower curtate of each cam surface 156,158,160,162,164,166, thereby collar 122A, 122B, 122C are moved between joint and released position.Because the rotation of pin 130A-D causes collar 122A, 122B, 122C axially to move around along bar 108; Therefore can pin 130A-D be called cam-follower, can abbreviate collar 122A, 122B, 122C and/or cam surface 156,158,160,162,164,166 as cam.Like this, mating system example of the present invention can comprise selector, one or more weight engagement member (for example, for example collar 122A-C) and camming.Camming can comprise one or more cams as described herein and one or more cam-follower.The components all of mating system is the example that is used to make one or more weight engagement members mobile device between the primary importance and the second place.
It is understandable that the alternating pattern of the cam surface 156,158,160,162,164,166 shown in the figure just is used for illustration.Cam surface 156,158,160,162,164,166 can as required or be expected to be provided with, to allow to select the weight 104 of any type.
Referring now to Fig. 7-13,, it has shown another exemplary embodiment according to exercise weight of the present invention system 200.Because exercise weight system 200 is similar to exercise weight system 100 in many aspects, therefore will concentrate on exercise weight system 200 exclusive parts, characteristic and function in the face of the discussion of exercise weight system 200 down.
As shown in Figure 7, exercise weight system 200 comprises that exercise increases the weight of thick stick 202, a plurality of weight 204 and be designed for to keep taking exercise the bearing 206 that increases the weight of thick stick 202 and/or a plurality of weight 204.Exercise increases the weight of thick stick 202 and comprises generally in exercise and increase the weight of the bar 208 (referring to Fig. 8) that extends between the end opposite of thick stick 202.Selector 210 is arranged on the bar 208 with weight installing rack 212A, 212B.The same with other selector of discussing here, selector 210 can be used as the handle that selector installation and exercise period are used to grip simultaneously.In an illustrated embodiment, weight installing rack 212A is installed on first end of bar 208, and weight installing rack 212B is installed on second end of bar 208, and selector 210 is installed on the bar 208 between weight installing rack 212A, 212B with rotating mode.Be similar to selector 110, selector 210 can be used for selecting weight 204 and is connected on the bar 208 and is used for gripping exercise at exercise period increasing the weight of thick stick 202.As shown in Figure 7, weight installing rack 212A, 212B respectively are 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.
Following discussion mainly concentrates on first end of exercise weight system 200, but it equally also can be applicable to its second end.Further with reference to Fig. 7, weight installing rack 212A comprises first end cap 214 and second end cap 216, and the weight separator.First and second end cap 214,216 and weight separator cooperate to limit the groove that is used to hold weight 204 jointly.First and second end cap 214,216 and weight separator for example are connected to each other through support 218, move along the axis of bar 208 so that prevent weight 204 basically.
Shown in Fig. 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 take exercise and increases the weight of on the thick stick 202.Mating system 215 comprises: selector 210; Cam set 220 around bar 208 settings; And the collar 222A, 222B, the 222C that center on cam set 220 settings.Cam set 220 and selector 210 are integrally formed or be connected to each other, and make the mobile meeting of selector 210 make cam set 220 produce corresponding moving.For example, when selector 210 when axis A rotates, cam set 220 is also rotated around axis A.
Collar 222A, 222B, 222C slidably are mounted to around cam set 220 and make collar 222A, 222B, 222C between released position and bonding station, to slide along the direction that is in substantially parallel relationship to axis A.As collar 222A, 222B, when 222C is positioned at the released position, weight 204 can be received by weight installing rack 212A.In case one or more weights 204 are received by weight installing rack 212A, collar 222A, 222B, 222C are movable to bonding station to be increased the weight of on the thick stick 202 so that optionally and securely one or more weights 204 are connected to take exercise.Therefore, collar 222A, 222B, 222C are the examples of weight engagement member.
As shown in Figure 8, cam set 220 comprises the cam path 224,226,228 that distaff at least partly 208 is extended.In an illustrated embodiment, cam path 224,226,228 is formed in the outer surface of the sleeve 221 that is installed on the bar 208.In this embodiment, sleeve 221 is connected on the selector 210, so that carry out related with the motion of cam path 224,226,228 selector 210.Sleeve 221 can be connected to each other directly with selector 210, integrally formed as single parts, or sleeve 221 can all be fixedly mounted on the bar 208 so that carry out their motion related 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 the bar 208 so that association is carried out in their motion.Be similar to cam surface 156,158,160,162,164,166, each cam path 224,226,228 defines respectively more near the left side and the right of weight 204 and helps the high portion that replaces that weight 204 engages and the pattern of lower curtate.
Fig. 9 has shown the perspective view of collar 222B.Collar 222B comprises tubular body 230, and it defines opening, receives bar 208 through this opening.Cam pin 232 extends in the opening of tubular body 230.When collar 222B is installed in 208 last times of bar shown in Figure 10 and 12, cam pin 232 is received in the cam path 226.As noticing the front, when selector 210 when axis A rotates, cam set 220 rotates around axis A.When cam set 220 when axis A rotates, cam pin 232 passes cam path 226 and in cam path 226, between high portion and lower curtate, moves.Cam pin 232 moves between joint and released position at the mobile collar 222B that causes between high portion and the lower curtate in cam path 226.When cam pin 232 was positioned at the high portion of cam path 226, collar 222B was arranged in bonding station.In contrast, when cam pin 232 was positioned at the lower curtate of cam path 226, collar 222B was arranged in the released position.In the embodiment shown in fig. 10, collar 222A, 222B, 222C are arranged in bonding station when moving to left (that is, towards end shown in the bar 208) along axis A, when moving to right (that is, towards selector 210) along axis A, be arranged in the released position.
Collar 222A, 222C are similar or identical with collar 222B, except the length of the tubular body of collar 222A, 222C differs from one another, and also are different from collar 222B.It should be understood, however, that collar 222A, 222B, 222C can form mutually the same.
Collar 222A, 222B, 222C comprise weight composition surface 234,236,238 respectively.Each weight composition surface 234,236,238 tubular body from collar 222A, 222B, 222C stretches out, and up at least two kinds of effects.At first, shown in figure 12, the bottom surface 250 of weight composition surface 234,236,238 contact brackets 218, this has prevented that basically collar 222A, 222B, 222C from rotating around axis A when axis A rotates in cam set 220.Secondly, as what below will specifically more discuss, weight composition surface 234,236,238 is designed at collar 222A, 222B, engages with weight 204 when 222C is positioned at bonding station.
Figure 11 has shown the perspective view of weight 204, and it optionally is connected to take exercise and increases the weight of on the thick stick 202.Weight 204 comprises groove 240, and this groove 240 can increase the weight of exercise the part of thick stick 202---for example bar 208 and collar 222A, 222B, 222C---is received in wherein.Weight 204 also comprises one or more collars composition surface, for example surperficial 242A, 242B. Collar composition surface 242A, 242B are designed to as collar 222A, 222B, when 222C is positioned at bonding station, engage with among collar 222A, 222B, the 222C at least one.As an example; When collar 222B when the released position moves to bonding station; Weight composition surface 236 will move on to collar composition surface 242A, 242B below, thereby weight composition surface 236 will engage collar composition surface 242A, 242B when increasing the weight of thick stick 202 and being picked up when taking exercise.Shown in figure 11, collar composition surface 242A, 242B can local extensions between the opposition side of weight 204.Perhaps, collar composition surface 242A, 242B can extend on the overall distance between the opposition side of weight 204.
Weight 204 also comprises the groove 248 that is formed on its bottom.Groove 248 is designed to be placed on when weight 204 pin or the tab of bearing 206 last times reception bearing 206.The pin of groove 248 and corresponding bearing 206 or tab can cooperate jointly and weight 204 remained vertical basically so that be placed on 206 last times of bearing at weight 204.
Figure 12 has shown that the exercise that fits together with position weight 204 on it increases the weight of the cross-sectional view of first end of thick stick 204.More specifically, selector 210 is installed on the bar 208 with sleeve 221, and collar 222A, 222B, 222C are installed on the sleeve 221 through the cam pin 244,232,246 that extends in the cam path 224,226,228.As discussing the front, selector 210 causes cam path 224,226,228 to rotate around axis A equally around the rotation of axis A, this cause again collar 222A, 222B, 222C engage and the released position between move.
Exercise weight system 200 comprises feedback mechanism, is used for the indication that provides one or more weights 204 to engage or unclamped to the user.The feedback mechanism of exercise weight system 200 is similar to brake and the recess system that the front is discussed to exercise weight system 100.Particularly, second end cap 216 comprises inner panel 252 and outside plate 254.Inner panel 252 is fixedly connected on first end cap 214 via support 218, makes inner panel 252 not rotate around axis A basically.In contrast, outside plate 254 is installed to or is connected on the selector 210, so that with the motion of outside plate 254 and the motion associated of selector 210.Like this, when selector 210 rotated around axis A, outside plate 254 also rotated around axis A and with respect to inner panel 252.
Brake 256 is connected in outside plate 254; This brake 256 for example is ball and spring, forced positioning bead, additional mode prepared material or other protrusion, its by towards inner panel 252 bias voltages or towards inner panel 252 extend in case be formed on inner panel 252 surfaces in a plurality of recesses 258 in one engage.When selector 210 and outside plate 254 when axis A rotates, brake 256 is mobile and engage between recess 258.When the user rotated selector 210 around axis A, brake 256 can be the user with recess 258 sense of touch and/or audio feedback is provided.For example, brake 256 and recess 258 combination that weight 204 or weight 204 can the be provided indication that when engaged or unclamped with collar 222A, 222B, 222C.In addition, the bond strength between brake 256 and the recess 258 is enough to also to prevent basically that outside plate 254 from increasing the weight of in exercise to rotate with respect to inner panel 252 between operating period of thick stick 202.In stoping and outside plate 252, the relative motion between 254 can prevent that selector 210 from rotating, and prevent collar 222A, 222B, 222C engage and the released position between move.
As noticing the front, the alternating pattern that each cam path 224,226,228 defines between high portion and the lower curtate so that when selector 210 when axis A rotates, impel collar 222A, 222B, 222C engaging and the released position between move.Figure 13 has shown the plane of cam set 220, reaches position relative to each other with the pattern that shows each cam path 224,226,228.These patterns of cam path 224,226,228 and relative to each other position make it possible to that some kinds of weights 204 combination selection property ground is connected to exercise and increase the weight of on the thick stick 202.
Figure 13 has shown four illustration position P1, P2, P3, the P4 of cam set 220, when it aligns with the cam pin 244,232,246 of collar 222A, 222B, 222C, can be to take exercise and increases the weight of thick stick 202 four different weights combinations are provided.That is, when cam set 220 rotates into make among the P1-P4 of position one when aliging with cam pin 244,232,246 around axis A, each collar 222A, 222B, 222C will move on to engage or the released position in.
For example; As shown in; When thereby cam set 220 is rotated position P1 when aliging with cam pin 244,232,246 around axis A; 244 relevant collar 222A will be arranged in bonding station with cam pin, and 232 relevant collar 222B will be arranged in the released position with cam pin, and 246 relevant collar 222C will be arranged in bonding station with cam pin.As collar 222A, when 222C is positioned at bonding station, there are two weights 204 will be connected to exercise and increase the weight of on the thick stick 202.
Thereby rotate position P2 when aliging with cam pin 244,232,246 when cam set 220 around axis A, collar 222A, 222B, 222C will all move on in the released position.As a result, not having weight 204 to be connected to exercise increases the weight of on the thick stick 202.In contrast, align with cam pin 244,232,246, will cause collar 222A, 222B, 222C all to move on in the bonding station, thereby engage three weights 204 thereby make cam set 220 rotate position P3 around axis A.When thereby cam set 220 rotation position P4 align with cam pin 244,232,246, collar 222A, 222B will move on in the bonding station, and collar 222C will move on in the released position.Shown in it should be understood that and described position P1-P4 be for the purpose of illustration only, cam set 220 also turns other position that becomes to make cam path 224,226,228 and aligns with pin 244,232,246, makes up so that engage various other weights 204.
Shown in figure 13, brake 256 is positioned to when the specific part of cam path 224,226,228 aligns with cam pin 244,232,246, be engaged with each other with recess 258.For example, brake 256 and recess 258 are positioned to as long as among cam pin 244,232,246 and the position P1-P4 shown in Figure 13 aligns, then brake 256 coupling recess 258.Engaging to the user provides one or more weights 204 to be installed to take exercise between brake 256 and the recess 258 increases the weight of on the thick stick 202 and takes exercise and increase the weight of operable sense of touch of thick stick 202 or audio feedback.
Like this, the example of mating system of the present invention comprises selector 210, cam pack 220, such as one or more collars of collar 222A, 222B, 222C, and camming.Camming comprises one or more cams, for example cam path 224,226,228 and one or more cam following face, and for example 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 that are used to make one or more weight engagement members mobile device between the primary importance and the second place.

Figure 16 has shown the perspective view of collar 322A.Collar 322A comprises tubular body 324, and this tubular body 324 defines opening 326, receives the part of bar 308 and selector 310 through this opening 326.Collar 322A also comprises the flange 328 that extends radially outwardly from tubular body 324.Flange 324 limits or comprises that cam surface 330, this cam surface 330 comprise high portion 332 and lower curtate 334.Shown in Figure 15 and 20, high portion 332 is positioned to than lower curtate 334 further from selector 310.In other words, high portion 332 with align along position on the length of bar 308 or position, and lower curtate 334 with align along the second place or position on bar 308 people's length.
Figure 17 has shown the perspective view of collar 322B.Collar 322B comprises tubular body 336, and this tubular body 336 defines opening 338, receives the part of bar 308 and selector 310 through this opening 338.Collar 322B also comprises the flange 340 that extends radially outwardly from tubular body 336.Flange 340 limits or comprises that cam surface 342, this cam surface 342 comprise a plurality of high 344 and a plurality of lower curtates 346.Shown in figure 17, cam surface 342 high portion and lower curtate 344, between 346 alternately.According to current embodiment, when collar 322B is installed in 308 last times of bar, high portion 344 is positioned to than lower curtate 346 further from selector 310.That is, the same with high portion with lower curtate 322,334, high portion 344 with align along position on the length of bar 308 or position, and lower curtate 346 with align along the second place on the length of bar 308 or position.
The width of high portion and lower curtate 344,346 is not must be identical, but can be identical or consistent.For example, the width of a lower curtate 346 (for example, the distance between the high portion 344 of two radially adjoinings) can be more greater or lesser than the width of another lower curtate 346.Similarly, one high 344 width (for example, the distance between the lower curtate 346 of two radially adjoinings) can be more greater or lesser than the width of another high portion 344.In addition, the high portion of collar 322B and lower curtate 344,346 can be axially aligned with the high portion of collar 322A and lower curtate 332,334 or depart from.The high portion of collar 322A, 322B and the alignment of lower curtate and/or depart from and to allow to select and the combination of fastening multiple weight 304.It is understandable that the alternating pattern of high portion shown in the figure and lower curtate 332,334,344,346 is exemplary.Cam surface 330,342 can as required or be expected to be provided with, to allow to select the weight 304 of any type.
Turn to Figure 18 to notice now, it has shown the perspective view of weight engagement member 320A, and it is basic similar or identical with weight engagement member 320B.Weight engagement member 320A comprises first end 348, second end 350 and central body 352.As stated, can first end 348 be connected on the support 318 with the mode of pivot or rigidity.For example, first end 348 can be formed with the hole 354 of the circular that extends through first end 348.Bar, bolt or other device can stretch out and get into the relative wall of support 318 from the end opposite in hole 354, thereby weight engagement member 320A is connected on the support 318.Can be designed to allow weight engagement member 320A to rotate or pivot in hole 354 and the bar that wherein holds around this bar.Perhaps, the opposition side of first end 348 can be contained in the relative wall of support 318 or from extending through said wall, thereby weight engagement member 320A can pivot as described here.In addition, first end 348 also can use machanical fastener (for example, bolt, clip (claims), pin), welding, mode such as bonding to be rigidly connected on the support 318.In this case, central body 352 deflections or crooked with allow second end 350 unclamp and bonding station between move.
Central body 352 comprises hole 356, receives the tubular body 324 of bar 308 and collar 322A through this hole 356.Weight engagement member 320A also comprises biasing member 358, will discuss as following, and biasing member 358 engages with support 318 or interact so that weight engagement member 320A is biased into the released position.In an illustrated embodiment, biasing member 358 is a part of integrally formed as first end 348, or is connected on first end 348.Biasing member 358 can adopt any suitable form, comprises elastomeric material, spring etc.
Second end 350 of weight engagement member 320A comprises weight claw 360 and brake 362.Weight claw 360 is designed at weight engagement member 320A and moves, engages with weight 304 when pivoting or bend to bonding station.Brake 362 be designed to cooperate with the cam surface 330 of collar 322A so that weight engagement member 320A unclamp and bonding station between move, pivot or crooked.
When collar 320A when axis A rotates, the high portion of cam surface 330 and lower curtate 332,334 be engage brakes 362 alternately.When high portion 332 engage brakes 362, weight engagement member 320A will move, pivot or bend to bonding station, and when lower curtate 334 engage brakes 362, weight engagement member 320A will move, pivot or bend to the released position.Like this, can brake 362 be called cam-follower, because its motion is along the high portion and the lower curtate of cam surface 330.Brake 362 can be ball and spring, forced positioning bead, additional mode prepared material or other protrusion, and it stretches out towards cam surface 330 from weight engagement member 320A.
Figure 19 has shown optionally to be connected to and has tempered the perspective view increase the weight of the weight 304 on the thick stick 302.Weight 304 comprises groove 364, and this groove 364 can be tempered a part that increases the weight of thick stick 302---for example bar 308, weight engagement member 320A, and 320B and/or collar 322A, 222B---be received in wherein.Weight 304 also comprises claw groove 366, and it is designed at least a portion that when weight engagement member 320A or 320B are positioned at bonding station, receives weight claw 360.Shown in figure 19, claw groove 366 can local extension between the opposition side of weight 304.Perhaps, claw groove 366 can extend on overall distance between the opposition side of weight 304.
Figure 20 has shown the partial cross section view of exercise weight system 300, and it has shown that a weight 304 engages with weight engagement member 320A, and another weight 304 does not then engage with weight engagement member 320B.In an illustrated embodiment, selector 310 rotates around axis A, thereby impels collar 322A, 322B to produce corresponding rotation.As shown in, collar 322A is located such 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, thereby 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 pivot or crooked 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 pivot or crooked degree.
Shown in figure 20, when weight engagement member 320A moved to bonding station, biasing member 358 was pressed against the bottom surface 368 of support 318.The interaction between 368 of biasing member 358 and surface with weight engagement member 320A towards the released position bias voltage.Yet biasing member 358 and/or surface 368 can be designed to allow weight engagement member 320A is pivoted to bonding station, and be shown in figure 20.For example, in an illustrated embodiment, surface 368 is processed by elastomeric material (for example, rubber, foam etc.), and this elastomeric material can that kind shown in figure 20 receive biasing member 358 compressions when weight engagement member 320A is pivoted to bonding station.Yet when the lower curtate 334 on the brake 362 joint collar 322A, the elastic nature on surface 368 is with bias voltage or force weight engagement member 320A to move or be pivoted to the released position.Perhaps, surface 368 can be the cardinal principle rigidity, and biasing member 358 can be processed by the elastomeric material that weight engagement member 320A is biased into the released position.
Shown in figure 20, exercise weight system 300 comprises feedback mechanism, the indication that it provides one or more weights 304 to engage or unclamped to the user.The feedback mechanism of exercise weight system 300 is similar to the feedback mechanism of exercise weight system 200.Particularly, second end cap 316 is fixedly attached on the bar 308 and first end cap 314 via support 318, thereby second end cap 316 does not rotate with respect to bar 308 basically.As noticing the front, selector 310 rotate with respect to bar 308 in case make weight engagement member 320A, 320B engage and the released position between move.Like this, selector 310 rotates with respect to second end cap 316.
Brake 370 is connected on second end cap 316; This brake 370 for example is ball and spring, forced positioning bead, additional mode prepared material or other protrusion, its towards selector 310 bias voltages or extension in case be arranged on selector 310 surfaces in a plurality of recesses 372 in one engage.When selector 310 distaffs 308 were rotated, brake 370 moved between recess 372 and engages.When the user rotated selector 310, brake 370 can be the user with recess 372 sense of touch and/or audio feedback is provided, thus the combination that shows weight 304 when or weight 304 with weight engagement member 320A, 320B engages or unclamp.In addition, the bond strength between brake 370 and the recess 372 is enough to also prevent basically that selector 310 from rotating with respect to second end cap 316 during using exercise to increase the weight of thick stick 302, thereby prevents that weight 304 from increasing the weight of thick stick 302 at exercise period from exercise and breaking away from.
As noticing the front, the alternating pattern that cam surface 330,342 defines between high portion and the lower curtate, this alternating pattern selector 310 when axis A rotates, impel weight engagement member 320A, 320B engaging and the released position between move.These alternating patterns and high portion and lower curtate allow that at the last relative position of collar 320A, 320B multiple weight 304 combination selection property ground is connected to exercise to be increased the weight of on the thick stick 302.It is understandable that the alternating pattern of the cam surface 330,342 shown in the figure just is used for illustration.Cam surface 330,342 can as required or be expected to be provided with, to allow to select the weight 304 of any type.
According to disclosure herein, it is understandable that the parts of mating system 315 are the example that is used to make one or more weight engagement members mobile device between the primary importance and the second place.
Weight installing rack 312A can comprise the locking mechanism similar or identical with foregoing locking mechanism 124, its be used to prevent weight engagement member 320A, 320 exercise increase the weight of unclamping when thick stick 302 moves apart bearing 306 and bonding station between move.Be placed on 306 last times of bearing when exercise increases the weight of thick stick 302, releasably locking mechanism rotates to allow selector 310 and collar 322A, 322B, thus weight engagement member 320A, 320 can unclamp and bonding station between move.Locking mechanism can be designed to also to prevent that selector 310 and collar 322A, 322B from moving with respect to other parts that exercise increases the weight of thick stick 302 when exercise increases the weight of thick stick 302 and moves apart bearing 306, thus prevent weight engagement member 320A, 320B exercise increase the weight of that thick stick 302 is engaging not in bearing 306 time and the released position between move.
Now notice is turned to Figure 21-23, it has shown another exemplary embodiment according to exercise weight of the present invention system 400.Because exercise weight system 400 is similar to exercise weight system 100,200 and 300 in many aspects, therefore will concentrate on exercise weight system 400 exclusive parts, characteristic and function in the face of the discussion of exercise weight system 400 down.
Shown in figure 21, exercise weight system 400 comprises that exercise increases the weight of thick stick 402, a plurality of weight 404 and be designed for to keep taking exercise the bearing 406 that increases the weight of thick stick 402 and/or a plurality of weight 404.Exercise increases the weight of thick stick 402 and comprises generally in exercise and increase the weight of the bar 408 (referring to Figure 22-23) that extends between the end opposite of thick stick 402.Bar 408 has the longitudinal axis A that between its end opposite, extends.Selector 410 is arranged on the bar 408 with weight installing rack 412A, 412B.Selector 410 is installed on the bar 408 in a movable manner, makes selector 410 to rotate around longitudinal axis A and with respect to bar 408.The same with other selector of discussing here, selector 410 can be used as the handle that selector installation and exercise period are used to grip simultaneously.In an illustrated embodiment, weight installing rack 412A is installed on first end of bar 408, and weight installing rack 412B is installed on second end of bar 408, and selector 410 is installed on the bar 408 between weight installing rack 412A, 412B.Shown in figure 21, weight installing rack 412A, 412B respectively are designed for and receive maximum four weights 404.Will be understood that weight installing rack 412A, 412B can be designed for and receive more or less weight 404.
Weight installing rack 412A comprises first end cap 414 and second end cap 316 and weight separator.First and second end cap 414,416 and weight separator cooperate so that limit the groove that holds weight 404 at least partly jointly.First and second end cap 414,416 and weight separator for example are connected to each other through support 418, move along the axis A of bar 408 so that prevent weight 404 basically.
Shown in Figure 22-23, weight installing rack 412A comprises being designed for optionally and securely weight 404 being connected to take exercise and increases the weight of the mating system 415 on the thick stick 402.Mating system 415 comprises selector 410, one or more weight engagement member and one or more collar.One or more weight engagement members are relevant with each weight 404, and optionally are moved into and engage with weight 404 or separate, so that optionally engage or unclamp weight 404.In an illustrated embodiment, be implemented as here clamp two weight engagement member 420A, 420B is depicted as is associated with near the weight 404 that is positioned at bar 408 first ends.Though do not show, each other weight 404 also has two relevant with it weight engagement members.It should be understood that each weight 404 also can have a relevant with it weight engagement member, perhaps can have relevant with it three or more a plurality of weight engagement member.
Weight engagement member 420A, 420B are installed on first and second end cap 414 of being connected in weight installing rack 412A, the bar between 416 424. Weight engagement member 420A, 420B make weight engagement member 420A, 420B can distaff 424 between released position and bonding station, pivot or rotate being mounted on the bar 424.For example, each weight engagement member 420A, 420B can have to pivot and be connected to first end on the bar 424, thus allow second end unclamp and bonding station between pivot or rotate.In further embodiments; But the first end rigidity of each weight engagement member 420A, 420B or be fixedly attached on the bar 424, and the part of weight engagement member 420A, 420B can deflection or crooked with second end that allows weight engagement member 420A, 420B unclamp and bonding station between move.When weight engagement member 420A, 420B unclamping and bonding station between when moving, weight engagement member 420A, 420B move more near and further from bar 408.
In an illustrated embodiment, bar 424 has the longitudinal axis B of the longitudinal axis A that is roughly parallel to bar 408.Therefore, weight engagement member 420A, 420B pivot or rotation around the axis that is roughly parallel to longitudinal axis A (that is axis B).Like this, in an illustrated embodiment, weight engagement member 420A, 420B unclamp and bonding station between motion roughly be basically perpendicular in the plane of longitudinal axis A.
Notice that as the front mating system 415 also comprises one or more collars.Though comprise single collar 422 in an illustrated embodiment, it is understandable that, also can adopt a plurality of collars in the present invention.Collar 422 is mounted on bar 408 and makes the athletic meeting of selector 410 cause the corresponding sports of collar 422.For example, selector 410 can be connected on the collar 422 or be integrally formed therewith, so as the motion of selector 410 and collar 422 to be carried out related, thereby when selector 410 when axis A rotates, collar 422 also rotates around axis A.Will discuss as following, collar 422 impels weight engagement member 420A, 420B between released position and bonding station, optionally to pivot or rotates around the rotation of axis A.When the weight engagement member was positioned at the released position, weight 404 can be received by weight installing rack 412A.In case one or more weights 404 are received by weight installing rack 412A, the weight engagement member can pivot or turn to bonding station and increase the weight of on the thick stick 402 so that optionally and securely one or more weights 404 are connected to take exercise.
Figure 22-23 has shown the perspective view of the part of collar 422.Collar 422 defines opening, receives bar 408 through this opening.Collar 422 also comprises the cam surface 426 with high portion 428 and lower curtate 430.Shown in Figure 22-23, high portion 428 is positioned to than lower curtate 430 more radially away from bar 408.Though show, collar 422 also comprises one or more other cam surfaces, and each cam surface has one or more high and lower curtates.Each other cam surface can be related with one or more weight engagement members, and said weight engagement member is related with one or more weights again.Therefore, though the discussion of this part concentrates on cam surface 426, weight engagement member 420A, the weight 404 of 420B and end it should be understood that each weight 404 all is associated with one or more weight engagement members and one or more cam surface.It should be understood that various weight engagement members and cam surface can axially be provided with so that align with one or more weights 404 or be associated along the length direction of bar 408.
The width of high portion and lower curtate 428,430 is not must be identical, but can be identical or consistent.For example, the width of a lower curtate 430 (for example, the distance between the high portion 428 of two radially adjoinings) can be more greater or lesser than the width of another lower curtate 430.Similarly, one high 428 width (for example, the distance between the lower curtate 430 of two radially adjoinings) can be more greater or lesser than the width of another high portion 428.Similarly, the high portion of collar 422 other cam surfaces also can have and cam surface 426 various patterns different or that differ from one another with lower curtate.In addition, the high portion of each cam surface and lower curtate can be axially aligned with the high portion of other cam surface and lower curtate or depart from.The alignment of high portion of cam surface and lower curtate and/or depart from and to allow to select 404 combinations of various weights and secure it to take exercise to increase the weight of on the thick stick 402.It is understandable that the high portion of collar 422 each cam surface and lower curtate can as required or be expected to be provided with, to allow to select the weight 404 of any type.
