Abstract

Described is a seat mechanism for use with a recumbent type stationary exercise bicycle where the seat can be adjusted along the longitudinal length of the bicycle. In this mechanism, the seat can be positioned along a longitudinal support member of the exercise bicycle using a latch mechanism and a release handle.

Description

Recumbent seat mechanism

Technical field

Mechanism described herein relates generally to exercising apparatus, and relates more particularly to be used in fixing chair mechanism of taking exercise on the bicycle.

Background technology

By bike by on the hills or having of riding of the mountain topography mountain region of craving for and road cyclist or general or " Sunday " cyclist think effective especially a kind of exercising with oxygen.And, provide by bike a kind of low impingement to take exercise, it is easy especially to knee and pin.As a result, it is all very popular in family and health club to be convenient to carry out the use of fixedly exercise bicycle of this exercise.

The seat adjustment capability is taken exercise at Recumbent and is also expected in the bicycle to have.Typically, thus the guiding mechanism on the mechanical device of these types allows seat to move horizontally or adapt to the user of different heights from the angled movement of horizontal line.For example, Life Fitness, it is a department of Brunswick company, a kind of Recumbent exercise machine device is provided, it is equipped with the seat that moves along guide rail, is combined with the tooth bar that is bolted to guide rail one side seat is remained on the appropriate location thereby be connected to handle on the spring-loading pin on seat one side.

Summary of the invention

Described herein is the mechanism that utilizes release handle and blocking mechanism (latch mechanism), and it allows the fixing exercise of Recumbent bicycle seat is carried out the position adjustment in order to the method that makes things convenient for of the various seat positions of selection is provided to the user.

The specific embodiment

Fig. 1 draws representative Recumbent and tempers bicycle 400, it has the typical Recumbent parts with the dotted line indication, it comprises: for example, framework 412 with central support portion 414, control panel 416 is totally with 418 driven units of indicating, handle 420, the seat frame 422 that is used for the supporting chair (not shown), and the back support frame 424 that is used for supporting the backrest (not shown).Fig. 1 also shows the preferred embodiment of the capable of regulating chair mechanism shown in the lines 426.Chair mechanism 426 comprises: be installed in the carriage supports parts 428 on the framework 412 above the central support portion 414, its cross section is drawn in Figure 26; Be connected to the balladeur train outer cover 430 on the seat frame 424; A pair of encirclement carriage supports parts 428 also are connected to the

Support bracket

432 and 434 of each end of balladeur train outer cover 430; And locking release handle 436.

Fig. 2 is shown in greater detail in the outside that does not have the chair mechanism 426 in balladeur train outer cover 430 situations a little.In this embodiment, seat frame 422 comprises a pair of longitudinal component 438 and 440 that seat can be connected thereto, and be fixed to longitudinal component 438 and 440 and back support frame 424 on a pair of cross member 442 and 444.

Except thereby carriage supports parts 428 had been removed the details of some interior sections that chair mechanism 426 is shown, Fig. 3 was similar to Fig. 1.Comprising tooth bar 446 is arranged, the upper inside surface 450 that it disposes a large amount of tooth section 448 and is fixed to carriage supports parts 428 as shown in Figure 7.Balladeur train 452 has one group of 8 runner 454-468, and they are installed at four axle 470-476 that are fixed on the balladeur train 452 and rotate.Also be connected with the blocking mechanism with 478 indications on the balladeur train 452, this blocking mechanism comprises ratchet 480, this ratchet 480 have in this embodiment be configured to tooth bar 446 in the pair of

end portions projection

482 and 484 of tooth section 448 engagement.

With reference to figure 4, this figure is the cross section right view of blocking mechanism 478 in the situation of removing balladeur train 452, and ratchet 480 is pivotably connected on the balladeur train 452 by rotating shaft 486.Ratchet holding member 488 operationally meshes with ratchet 480, and this ratchet holding member 488 is pivotably connected on the balladeur train 452 by rotating shaft or axle 490.Cable 496 is pivotably connected to the extension, bottom 494 of ratchet holding member 488 at point 492 places, this cable 496 passes the tie point 500 that pipe fitting 498 arrives on the protuberance 502, and this protuberance 502 forms the part of release handle 436.Release handle 436 is rotatably connected to balladeur train outer cover 430 via carrier structure 504 at pivotal point 506 places.

Fig. 5 A and 5B illustrate the operation of blocking mechanism 478.Usually handle 436 is in the reduction state shown in Figure 24 A, and wherein ratchet 480 fully and two engagements in the tooth section 448 on the tooth bar 446.Tend to keep ratchet 480 and the bias force of tooth section 448 to be provided by torsion spring 508 and ratchet holding member 488, thereby this ratchet holding member 488 provides wedging force (wedging force) to upper offset at ratchet 480 by another torsion spring 510, with the ratchet 480 of auxiliary maintenance with tooth bar 446 engagements.This will prevent balladeur train 452 and therefore prevent that seat from vertically moving along carriage supports parts 428.Shown in Fig. 5 B, the user upwards pulls handle 436, will pass to ratchet holding member 488 by cable 496, thereby it is rotated down.When on the ratchet holding member rotation holding member 488 with protruding shown in 512 time, ratchet 480 will be rotated down then and will break away from tooth bar 446.At this moment, balladeur train 452 is along carriage supports parts 428 Free-rollings on the runner 454-466, in order to allow user's moved seat to the desired position.Release handle 436 will cause

spring

508 and 510 to make ratchet 480 locking balladeur trains 452 and therefore lock seat to the appropriate location.

Fig. 6 draws the part of balladeur train 452 and blocking mechanism 478.Especially, Fig. 6 illustrates four center runners 456,458,464 and 466 and is raised with respect to four end runners 454,460,462 and 468.And Fig. 6 illustrates first runner 454 in balladeur train 452 left sides and the outer surface of last runner 460 is configured to V-arrangement, shown in 514 and 516.Remaining runner 456,458,464 and 466 flat outer surface that have shown in 518-528.

Fig. 7 provides the rear viewgraph of cross-section of carriage supports parts 428.Carriage supports parts 428 dispose a pair of

upper rall

530 and 532 with plane surface, and described plane surface provides slidingsurface for top or middle part runner 456,458,464 and 466.In the lower-left side, carriage supports parts 428 dispose the guide rail with groove, and it provides slidingsurface for the

runner

454 and 460 with V-arrangement outer surface 514 and 516.Have for

bottom runner

462 and 468 provides the guide rail 538 of the plane surface of slidingsurface and be configured on the lower right side of carriage supports parts 428.

Fig. 7 also shows balladeur train outer cover 430, and it surrounds carriage supports parts 428.Balladeur train 430 is by being fixed to the bottom 540 of balladeur train 452 with 542 one group of securing member of indicating, described securing member extends through a pair of and

carriages

544 and 546 outer cover 430 one.The bottom 540 of balladeur train also extends through the slit with 548 indications, and this slot arrangements is in the bottom of carriage supports parts 428, and extends along the length of parts 428.As a result, outer cover 430 can move along the carriage supports parts 428 with balladeur train 452.

The preferred embodiment of aforesaid Recumbent seat mechanism 426 has dramatic benefit.For example, capable of regulating chair mechanism 426 is trapped among its all operations parts in carriage supports parts 428 and the balladeur train outer cover 430 basically, thereby reduces the potential obstruction to the user.And the frame for movement of mechanism 426 allows release handle 436 to be positioned at the front of seat and just in time below seat, this is convenient especially to the user.
