Specifically, as shown in Fig. 2 being provided with upper-layer parking frame stop in the topside position of pillar 3 and lower floor position Part 31U and lower floor jiffy stand retainer 31L.As shown in figure 4, upper-layer parking frame retainer 31U is formed as more tending to upside then The bigger wedge-type shape of width, jiffy stand check plate 31 are stretched helical spring 312 (force application part) all the time towards the side of pillar 3 force (reference picture 6 (B)).Therefore, when jiffy stand 11 (and upper movable body 12 integral with it) moves upward, in jiffy stand Check plate 31 overcomes the active force (spring force) of draft helical spring 312 and taken a seat after crossing upper-layer parking frame retainer 31U Thereon surface and be locked.If the active force of draft helical spring 312 is overcome by the manual operation to action bars 313 to make Jiffy stand check plate 31 moves towards the rear, then can release the lock-out state of jiffy stand check plate 31.

On the other hand, as shown in Fig. 5, Figure 12, lower floor jiffy stand retainer 31L is formed as more trend downside, and then width is bigger Wedge-type shape, therefore, when jiffy stand 11 (and upper movable body 12 integral with it) moves downward, stop in jiffy stand Dynamic plate 31 overcomes the active force (spring force) of draft helical spring 312 and crosses and be seated at after lower floor jiffy stand retainer 31L Its lower surface and be locked.If the active force of draft helical spring 312 is overcome by the manual operation to action bars 313 to make to stop Vehicle frame check plate 31 moves towards the rear, then can release the lock-out state of jiffy stand check plate 31.

In addition, as shown in figure 1, the tire support 323 and linkage board 32 of jiffy stand 11 are via the link mechanisms such as connecting rod 324 (reference picture 26) and link, linkage board 32 be stretched helical spring 322 (force application part) all the time towards the side of pillar 3 exert a force (reference picture 6 (B)).If bicycle 110 is moved into (Figure 14 real vehicle state) towards jiffy stand 11, tire support 323 rolls forward, gram Take the active force (spring force) of draft helical spring 322 and linkage board 32 is retreated movement, on the other hand, if will from jiffy stand 11 Bicycle 110 takes out of (Figure 20 complete vehicle curb condition), then tire support 323 rolls backwards, utilizes draft helical spring 322 Active force and make linkage board 32 advance movement.

As shown in Figure 14~Figure 16, when real vehicle state, i.e. linkage board 32 retreats mobile, shape is protruded down from linkage board 32 Into upside abutting part 321 (abutting part) rear surface, with from the prominent downside abutting part 331 formed upward of bottom check plate 33 The preceding surface of (abutting part) is changed into crimped status, top chassis 10 (jiffy stand 11 and upper movable body 12) and bottom chassis 20 (lower movable body 21) links and can lifted in the state of integration.

Fig. 5 is back to, the ratio lower floor jiffy stand retainer 31L positions on the lower of pillar 3 are provided with bottom retainer 33L.Bottom retainer 33L is formed as more tending to the downside then bigger wedge-type shape of width, therefore, when (the bottom of bottom chassis 20 Movable body 21) when moving downward, in bottom, check plate 33 overcomes the active force of draft helical spring 332 and crosses bottom stop It is seated at its lower surface after part 33L and is locked.As shown in Figure 14~Figure 16, retired after real vehicle state, i.e. linkage board 32 When dynamic, bottom check plate 33 overcomes the active force of draft helical spring 332 to move and can release lock-out state towards the rear.

So, under the real vehicle state of jiffy stand 11, the lock-out state of bottom check plate 33 is released from, and top chassis 10 and bottom chassis 20 link be integrated, therefore, it is possible to make top chassis 10 and bottom chassis 20 integratedly lift.On bottom Chassis 20, only in the case where jiffy stand 11 is in real vehicle state, it can lift, stop in a manner of with the one of top chassis 10 In the case that vehicle frame 11 is in complete vehicle curb condition, it is locked in lower floor position and can not rises.

The concrete example for the jiffy stand 11 for possessing action bars 313 is shown in Figure 25, Figure 26.In the rear side positioned at jiffy stand 11 The tire gateway of end is fixed with pair of right and left reinforcing plate 111 (accessory).Action bars 313 is with relative to the energy of jiffy stand 11 The mode enough rotated crosses over the reinforcing plate 111 for being installed on left and right.Specifically, action bars 313 has：Boss portion 313a, its with The mode that can be rotated is installed on the fulcrum 111a set up between reinforcing plate 111,111；Arm 313c is rotated, it is from boss portion 313a extends along radial direction；And the handle part 313b of semi-cylindrical shape, it is formed at the leading section for rotating arm 313c.When Jiffy stand 11 is carrying out action bars 313 when topside position is in complete vehicle curb condition (reference picture 1) or real vehicle state (not shown) Latch-release operation when, handle part 313b is together with by the connection shaft 111b of the reinforcing plate 111,111 of left and right link by operating The hand of person is held.

In addition, when carried out in the lower floor position of jiffy stand 11 bicycle 110 take out of move into when, (the holding of action bars 313 Portion 313b) because the front-wheel 110F or trailing wheel 110R with bicycle 110 are contacted and are rotated, jiffy stand check plate 31 is made within moment Move towards the rear and release the lock-out state of itself and pillar 3 (in addition, hereinafter situation to wheel after etc. is chatted State).

So, either real vehicle state, complete vehicle curb condition, can be by rotating in the step-down operation of jiffy stand 11 The handle part 313b and connection shaft 111b of formula are held and mitigate the operating physical force of action bars 313 together, so as to one side pair Jiffy stand 11 carries out supporting while making it safely decline.

In addition, the 33S shown in Fig. 2 etc. is disposed on the peace of the pillar 3 of the opening position than bottom retainer 33L by the top Full retainer, such as in the case where being malfunctioned to bottom check plate 33 relative to bottom retainer 33L locking, Safety stopper 33S is as the safety device of the emergency lock of bottom check plate 33 to be played into function, it is used and bottom Structure same retainer 33L.In addition, as shown in Fig. 6 (B), upside abutting part 321 is formed as the channel-shaped of Y-shaped when looking up, Thereby increase during with overlooking with the contact surface of the triangular shaped prominent downside abutting part 331 (reference picture 13 (A) etc.) formed Accumulate and increase crimp force.

Next, the action for bicycle parking device 100 described above, is carried out according to the order of operation to overview Explanation.

<Holding state=jiffy stand complete vehicle curb condition, topside position>(Fig. 1~Fig. 6)

As shown in figure 4, the lower surface of jiffy stand check plate 31 be seated at upper-layer parking frame retainer 31U upper surface and by Locking.But sometimes because of the perseverance supported to top chassis 10 (jiffy stand 11 and upper movable body 12 of complete vehicle curb condition) The spring force of pressing spring 1 and cause jiffy stand check plate 31 lower surface as the figure with upper-layer parking frame retainer 31U Upper surface compare the state that slightly suspends and static.As shown in figure 5, the upper surface of bottom check plate 33 and bottom retainer 33L lower surface is abutted and is locked, and bottom chassis 20 (lower movable body 21) is carried out using the active force of gas spring 80 Supporting.

<In jiffy stand complete vehicle curb condition, decline>(not shown)

If handle part 313b is held and rotate action bars 313 and by upper-layer parking frame retainer 31U upper table Face and the latch-release of the lower surface of jiffy stand check plate 31, then top chassis 10 begin to decline.If handle part 313b is unclamped, Then jiffy stand check plate 31 is stretched helical spring 312 again towards the side of pillar 3 force.

<Jiffy stand complete vehicle curb condition, lower floor position>(Figure 11~Figure 13)

As shown in figure 12, after the rake that jiffy stand check plate 31 crosses lower floor jiffy stand retainer 31L, jiffy stand The upper surface of check plate 31 abuts and is locked with lower floor jiffy stand retainer 31L lower surface, utilizes the spring of constant force spring 1 Power supports to top chassis 10 (jiffy stand 11 and upper movable body 12 of complete vehicle curb condition).In addition, work as top chassis 10 And bottom chassis 20 is when being in lower floor position, bottom check plate 33 compared with the retainer 33L of bottom the side's of facing slightly downward movement and Lower surface no longer with bottom retainer 33L abuts (reference picture 12；But the locking solution not stayed in after moving towards the rear Except position, but the lockable position stayed in after moving downward).

<Jiffy stand carries state, lower floor position>(Figure 14~Figure 16)

As shown in figure 14, in chronological sequence order shifts to bicycle 110 is equipped on into jiffy stand 11 to real vehicle state Situation illustrate.

The stage that (1-1) front-wheel 110F contacts with action bars 313

If the front-wheel 110F (wheel formerly moved into) of bicycle 110 contacts with action bars 313 (handle part 313b), grasp Make bar 313 to rotate, jiffy stand check plate 31 moves and releases the lock-out state of itself and pillar 3 towards the rear within moment.Now, Tire support 323 rolls backwards, bottom check plate 33 is advanced mobile by linkage board 32 and is in relative to pillar 3 Lock-out state, and abutting part 321,331 is in crimping releasing state, and therefore, the spring-force driven dual of constant force spring 1 is in jiffy stand 11 (traction object here is single top chassis 10).But due to having carried bicycle 110 in jiffy stand 11 About 1/2 weight, therefore, jiffy stand 11 (top chassis 10) do not rise.Further, if front-wheel 110F passes through action bars 313 (handle part 313b) is rotated and resetted, and jiffy stand check plate 31 moves and recovers its lock-out state with pillar 3 forward.

The stage that (1-2) trailing wheel 110R contacts with action bars 313

If the trailing wheel 110R (wheel subsequently moved into) of bicycle 110 contacts with action bars 313 (handle part 313b), grasp Make bar 313 to rotate, jiffy stand check plate 31 moves and releases the lock-out state of itself and pillar 3 towards the rear within moment.Now, Tire support 323 rolls backwards, bottom check plate 33 is advanced mobile by linkage board 32 and is in relative to pillar 3 Lock-out state, and abutting part 321,331 is in crimping releasing state, and therefore, the spring-force driven dual of constant force spring 1 is in jiffy stand 11 (traction object here is single top chassis 10).But carry the 1/2 of bicycle 110 in jiffy stand 11 Weight above, therefore, jiffy stand 11 (top chassis 10) does not rise.Further, if trailing wheel 110R passes through action bars 313 (handle part 313b) is rotated and resetted, and jiffy stand check plate 31 moves and recovers its lock-out state with pillar 3 forward.

(2) front-wheel 110F makes the stage that tire support 323 is acted

If the front-wheel 110F (wheel formerly moved into) of bicycle 110 makes tire support 323 roll forward, by Linkage board 32 makes bottom check plate 33 retreat mobile and be changed into releasing the state with the locking of pillar 3, and abutting part 321,331 It is changed into crimped status, therefore, the spring force of constant force spring 1 and the extrusion pressure of gas spring 80 act on jiffy stand 11 (here Traction object be top chassis 10 and bottom chassis 20 after integration).But due to jiffy stand check plate 31 forward Move and maintain its lock-out state with pillar 3, therefore, jiffy stand 11 (top chassis 10 and bottom chassis 20) does not rise.

<Jiffy stand real vehicle state, begin to ramp up from lower floor position>(not shown)

Operator tramples handle part 313b and rotates action bars 313, so that jiffy stand check plate 31 moves towards the rear. If by the latch-release of lower floor jiffy stand retainer 31L lower surface and the upper surface of jiffy stand check plate 31, top chassis 10 and bottom chassis 20 begun to ramp up in the state of integration.If unclamping handle part 313b, jiffy stand check plate 31 is drawn Helical spring 312 is stretched to exert a force towards the side of pillar 3 again.

<Jiffy stand real vehicle state, topside position>(Figure 17~Figure 19, Figure 16)

Jiffy stand check plate 31 crosses upper-layer parking frame retainer 31U rake, the lower surface of jiffy stand check plate 31 It is seated at upper-layer parking frame retainer 31U upper surface and is locked.But sometimes because to top chassis 10 and bottom chassis The active force of 20 constant force springs 1 supported and gas spring 80 and cause jiffy stand check plate 31 lower surface with upper strata Jiffy stand retainer 31U upper surface is static compared to the state slightly to suspend.

<Jiffy stand is unloaded state, starts auto-returned in lower floor position>(Figure 20~Figure 22)

In chronological sequence order shifts to unloading bicycle 110 from jiffy stand 11 as shown in Figure 20 to complete vehicle curb condition Situation illustrate.

(1) front-wheel 110F makes the stage that tire support 323 is acted

If the front-wheel 110F (wheel subsequently taken out of) of bicycle 110 makes tire support 323 roll backwards, by Linkage board 32 makes bottom check plate 33 advance mobile and be changed into the lock-out state relative to pillar 3, and abutting part 321,331 becomes To crimp releasing state, therefore, in jiffy stand 11, (traction object here is on single to the spring-force driven dual of constant force spring 1 Portion's chassis 10).But jiffy stand check plate 31 moves and maintains the lock-out state relative to pillar 3 forward, therefore jiffy stand 11 (top chassis 10) do not rise.

The stage that (2-1) trailing wheel 110R contacts with action bars 313

If the trailing wheel 110R (wheel formerly taken out of) of bicycle 110 contacts with action bars 313 (handle part 313b), grasp Make bar 313 to rotate, jiffy stand check plate 31 moves and releases the lock-out state of itself and pillar 3 towards the rear within moment.Now, Tire support 323 rolls backwards, bottom check plate 33 is advanced mobile by linkage board 32 and is in relative to pillar 3 Lock-out state, and abutting part 321,331 is in crimping releasing state, and therefore, the spring-force driven dual of constant force spring 1 is in jiffy stand 11 (traction object here is single top chassis 10).But jiffy stand 11 still carry the 1/2 of bicycle 110 with On weight, therefore, jiffy stand 11 (top chassis 10) does not rise.Further, if trailing wheel 110R by, action bars 313 ( Hold portion 313b) rotate and reset, jiffy stand check plate 31 moves and recovers its lock-out state with pillar 3 forward.

The stage that (2-2) front-wheel 110F contacts with action bars 313

If the front-wheel 110F (wheel subsequently taken out of) of bicycle 110 contacts with action bars 313 (handle part 313b), grasp Make bar 313 to rotate, jiffy stand check plate 31 moves and releases the lock-out state of itself and pillar 3 towards the rear within moment.Now, Tire support 323 rolls backwards, bottom check plate 33 is advanced mobile by linkage board 32 and is in relative to pillar 3 Lock-out state, and abutting part 321,331 is in crimping releasing state, and therefore, the spring-force driven dual of constant force spring 1 is in jiffy stand 11 (traction object here is single top chassis 10).Thus, lead in front-wheel 110F from the tire gateway of jiffy stand 11 While mistake, jiffy stand 11 (top chassis 10) since bottom chassis 20 separate and automatically rise (auto-returned).

<Jiffy stand is unloaded state, from lower floor's position auto-returned>(Figure 23, Figure 24)

As shown in figure 23, top chassis 10 is after jiffy stand check plate 31 crosses lower floor jiffy stand retainer 31L, still because The spring force of constant force spring 1 and lasting rising.But under the upper surface due to bottom check plate 33 and bottom retainer 33L Surface abuts and is changed into lock-out state, and therefore, bottom chassis 20 only slightly rises mobile and stays in lower floor position.So, by In the locking of jiffy stand check plate 31 releasing and abutting part 321,331 crimped status releasing and bottom check plate 33 Lock out action between be slightly provided with the time difference (time lag), therefore, the auto-returned of top chassis 10 rises and bottom chassis 20 locking stops reliably playing function.

<The excessive rising at topside position mainly to be played a role under the state of unloading of jiffy stand prevents>(reference picture 4)

As shown in figure 4, when with jiffy stand unload state auto-returned rise when, even if crossing upper-layer parking frame retainer In the case that the rate of climb of 31U and top chassis 10 (jiffy stand 11) does not also reduce, air damper 90 (buffer) it is slow Rush portion 90A to abut with upper movable body 12 (or jiffy stand 11), so that top chassis 10 slowly stops in topside position Only.The air damper 90 is installed on space 382 in the pillar of rear side in a manner of causing piston rod 90R front end downward Interior top, there is buffer part 90A in its front end, acted because with the abutting of upper movable body 12, top chassis 10 is applied Cushioning effect when abutting (shock absorbing effect) that is,.The spring force of constant force spring 1 is relatively large, jiffy stand 11 is automatic Scene steeply risen during return etc., the cushioning effect of air damper 90 effectively play function.

Circulation performs the action of a bicycle parking device 100 in the above described manner, is back to standby shown in Fig. 1~Fig. 6 State and stop.

So, in chronological sequence sequentially it is divided into two stages and carries out bottom chassis 20 using bottom check plate 33 to branch The action (and the action for releasing the crimped status of abutting part 321,331) and utilize jiffy stand check plate 31 will that post 3 locks The action that top chassis 10 unlocks from pillar 3, therefore, auto-returned construction will not malfunction and can reliably play work( Energy.Now, by according to bicycle 110 relative to the disengaging of jiffy stand 11 and the action of the linkage board 32 of movement portion stops directly down Dynamic plate 33 transmits, and thus, it is possible to realize the simplification of construction and improve the stability of action, therefore, contributes to the raising of durability.

Next, the wheel braking part 6 of bicycle parking device 100 is illustrated.

As shown in Figure 14 and Figure 17, wheel braking part 6 is arranged at jiffy stand 11.Jiffy stand 11 is in order to by the bicycle of carrying 110 wheel 110F, 110R is imported and is formed as channel configuration, and is had：Turned on one's side as the bicycle 110 for preventing from carrying Prevent from toppling over the side guides 62 of unit；As the tire support 323 of wheel support unit, when it is to carrying in guide Enter wheel to be kept and the importing position of regulation bicycle 110；And as wheel protection location (suspend and suppress unit) Tire protection part 60, it suppresses the suspension for rising first importing wheel when stopping.

Side guides 62 are along jiffy stand length direction in the face side of bicycle 110 of carrying and the both sides of rear side The sheet material or bar for the strip that (fore-and-aft direction) is set respectively.Here pillar 3 is fixed in one end of side guides 62, The other end is fixed on the rear end side of the jiffy stand 11 of the opposite side as pillar 3, and has rib 61, and the rib 61 exists On the length direction of jiffy stand 11 one at more than position halfway and the jiffy stand 11 of underface link.Furthermore, it is possible to Prepare to split to assemble them on the basis of side guides 62 and jiffy stand 11 respectively, but can also be by side guides 62 Formed and be integrated with jiffy stand 11.

First importing wheel (the front-wheel 110F in Figure 14 and Figure 17) when tire support 323 is to carrying is kept simultaneously The importing position of bicycle 110 is provided, the tire support 323 is arranged at the bottom of the jiffy stand 11 of channel configuration.In addition, wheel As long as the structure that tire supporting member 323 is kept for the importing position of regulation bicycle 110 to first importing wheel is i.e. Can or the other modes different from this configuration example.

Tire protection part 60 is that the side of the side in the side guides 62 of face side and rear side are arranged at is drawn Assigned position in guiding element 62 between tire support 323 and pillar 3 is as starting point and after extending upward, via around The top 60a (direction transformation portion) for first importing wheel (the front-wheel 110F in Figure 14 and Figure 17) extends and reaches the opposing party downward Side guides 62 inverted U-shaped part.Here tire protection part 60 is arranged to：At least under than jiffy stand real vehicle state The pivot of first importing wheel (the front-wheel 110F in Figure 14 and Figure 17) of bicycle 110 make by the position of the side of pillar 3 Top 60a is obtained above the first importing wheel to pass through.Further, tire protection part 60 here is arranged to more tend to top 60a sides are then closer to the tilted shape of the side of pillar 3.Furthermore, it is possible to prepare tire protection part 60 in split respectively and side is drawn They are assembled on the basis of guiding element 62, but tire protection part 60 and side guides 62 can also be formed and are integrated.

So, on the basis of side guides 62, it is additionally provided with tire support 323 in jiffy stand 11 and tire is protected Guard 60, therefore, even if when formerly importing wheel (the front-wheel 110F in Figure 14 and Figure 17) because of the impact when upper strata stops When being suspended from jiffy stand, it can also prevent wheel from departing from, coming off, additionally it is possible to damping vibration noise.

Finally, gas spring 80 is described in detail.

In the conventional bicycle parking device shown in patent document 1, substitute the gas spring 80 in this configuration example and adopt With constant force spring (the second constant force spring in patent document 1).However, under the constant force spring mode of patent document 1, such as When the rated load relative to the 25kgf of constant force spring carries the light weight bicycle less than 15kgf, in order to suppress jiffy stand Rapidly rise and relax the vibration noise along with the unexpected stopping on upper strata, it is possible to result in the need for adjusting again for spring force The state of affairs of whole, additional adjustment.On the other hand, if being set to the structure using gas spring 80 as this configuration example, envelope is utilized Enter the gas of the sealing space inside cylinder 80S and play the conjunction to bicycle 110 and bottom chassis 20 under real vehicle state Function that meter load is drawn, deceleration, constant speed function and upper strata towards upper strata stop position and when pulling upward are stopped The only pooling feature of opening position, it can also make in the case that the individual weight for the bicycle for being equipped on jiffy stand changes The rate of climb of jiffy stand is stable and suppresses the generation of vibration noise, so as to realize stable and quietly parking in the running The rising of frame.Further, around transmission mechanism 8 is hung, gas spring 80 can compactly be held by using including movable pulley 8M Receive and be configured inside pillar 3, required initial investment, maintenance cost hereafter, are also improved durable during so as to inhibit setting Property.

But in the case of using gas spring mode as this configuration example in bicycle parking device 100, produce such as Lower problem.

That is, the lag issues of gas spring.The feelings of constant force spring are used only in the rising in jiffy stand as in the past The spring force to be played a role under condition, during the rising of jiffy stand is identical with the spring force to be played a role during decline, and therefore, user makes It can act jiffy stand with roughly the same power when jiffy stand rises and when declining.However, in gas spring In the case of, lag, therefore, the spring force to be played a role in the protrusion of piston rod and the bullet to be played a role when being retracted into due to existing Difference is produced between spring force.Therefore, it is necessary to which user makes parking when rising jiffy stand and when declining with different powers Frame acts.The result is that, alternatively it is conceivable to the lower reduction of speed that is light and making jiffy stand of operation when for example declining jiffy stand than anticipation Degree become too fast or make operation needs that jiffy stand rises beyond anticipation power and jiffy stand rise consuming time etc., Because the difference of power and caused by perplex example.

In order to solve such new problem, in Figure 27 A~Figure 27 C, if cylinder 80S internal diameter is set into D₀, by piston Bar 80R diameter is set to d₀, by the area (compression face of the compression face of piston 80P rostral (that is, cylinder side installation portion 80BS sides) Product) it is set to AH₀And the area (compression area) of the compression face of piston 80P bar side (that is, bar side installation portion 80BR sides) is set to AR₀, then it is expressed as follows.

(1)AH₀=π D₀ ²/4

(2)AR₀=AH₀-πd₀ ²/ 4=π (D₀+d₀)(D₀-d₀)/4

Now, compression area ratio r₀It is expressed as.

(3)r₀=AR₀/AH₀=(D₀+d₀)(D₀-d₀)/D₀ ²

Moreover, in this configuration example, by the compression area ratio r₀It is adjusted to meet following relation.

(4)0.77≤r₀≤0.92

So, by by the compression area ratio r of gas spring 80₀It is set to larger and relatively reduces in the prominent of piston rod Go out side and be retracted into caused by side to lag, thus mitigate the jiffy stand uplifted side (that is, piston rod protrudes side) under real vehicle state And jiffy stand declines the operating physical force of the user needed for side (that is, piston rod is retracted into side), when can realize the lifting of jiffy stand 11 Operational raising.

In addition, in this configuration example, using D₀=30mm, d₀=12mm, r₀=0.840 value.Wherein, on compression face Product ratio r₀, it is preferably in 0.80≤r₀≤ 0.89 scope, is more preferably in 0.82≤r₀≤ 0.87 scope.If more than upper State higher limit, it is likely that flexing is produced in piston rod, on the other hand, if being less than lower limit, when particularly jiffy stand rises Operating physical force increase, People to shut-down operation of bicycle of powered dynamic auxiliary device etc. be possible to produce obstacle.

In addition, in the gas spring 80 of this configuration example, based on the extrusion pressure PF directed downwardly relative to piston rod 80R₀And The auxiliary force AF that the rising of jiffy stand 11 obtain, to real vehicle state is aided in₀For 147N~245N [=15kgf~ 25kgf].Gas spring 80 has following structure：So that working fluid (the inertia compression in two rooms 801,802 is enclosed respectively Gas) circulated through being formed from piston 80P one or more throttle orifice 80F, cylinder bore diameter is being set to D₀, by piston rod Diameter is set to d₀, each orifice diameter is set to k_i(i=1~n), in the case that throttling hole number is set into n, 1 table of mathematical expression The gas of the gas spring 80 shown averagely circulates index x₀Value be adjusted to 5≤x₀≤25。

【Mathematical expression 1】

In this configuration example, using D₀=30mm, d₀=12mm, n=1, k₁=1.0mm, x₀=21.0 value.It is in addition, living The extrusion pressure PF of stopper rod₀(also referred to as gas reaction force) is by diameter of piston rod d₀With inclosure gas pressure p₀Determine (PF₀=p₀× πd₀ ²/4).In addition, by using movable pulley 8M, can be by AF₀It is decreased to PF₀One of integer part (herein, AF₀=PF₀/ 2)。

By by x₀(gas averagely circulate index) is adjusted to above range, can be by under the real vehicle state of jiffy stand 11 The rate of climb of bicycle 110 is defined as the scope in 0.5m/s~1.0m/s.Actually when utilization bicycle parking device 100 When, the rate of climb of jiffy stand 11 is too fast or problem be present slowly excessively, in fact, ideal velocity is with 1.5sec~2.0sec Rise the total length (being here 1.2m) of jiffy stand stroke.By by x₀Above range is adjusted to, can realize and stop under ideal velocity The rising of vehicle frame 11.

In addition, x₀The scope of (gas averagely circulate index) is preferably defined as 7≤x₀In the range of≤23, more preferably provide For 8≤x₀In the range of≤21.If exceeding above-mentioned higher limit, circulating resistance increase, particularly it is likely to result in moving in the winter time Make bad.If in addition, being less than above-mentioned lower limit, circulating resistance reduces, and is particularly likely to result in drastically in summer, overheat Rise.

Above-mentioned basic structure example is only example.The basic structure of bicycle parking device is not limited to this, as long as The purport of claims is not departed from, what can also be added and be omitted based on the knowledge of those skilled in the art etc. is each Kind change.

In above-mentioned basic structure example, hang around movable pulley 8M and fixed pulley 8F and bottom chassis 20 is drawn Wire rod 8w can be set to the connecting members such as rope, band, chain.

, can on the linear guiding mechanism 82G for being configured to that there is roller 821 and track 831 in above-mentioned basic structure example Multiple rolling elements (ball or roller bearing) are used between linear track and linear balladeur train to substitute said structure " LM guiding pieces " (THK Co., Ltd.'s registration mark) isoline guiding piece (being also commonly referred to as Linear guide).Thereby, it is possible to form The linear guiding mechanism of higher precision.

Constant force spring 1 (the first forcing unit) in above-mentioned basic structure example can be set to other force application parts, such as can To use spring or counterweight part.For spring, can use be made up of metals such as spring steel metal spring (for example, Helical spring, leaf spring etc.), the nonmetallic spring that is made up of synthetic rubber, synthetic resin etc. is (for example, damper made of rubber Deng), the fluid spring (for example, air spring, gas spring, oil damper etc.) that is made up of air, oil etc. it is any, may be used also So that different types of spring is applied in combination.In the embodiment next recorded, auxiliary gas is used to substitution constant force spring 1 The situation of spring 81 illustrates.

(embodiment)

Embodiments of the invention are illustrated using Figure 28~Figure 43.

Mainly substitution constant force spring 1 and use auxiliary gas spring 81 and auxiliary around hang this point of transmission mechanism 800, And the gas spring 80 used in basic structure example and movable pulley 8M, fixed pulley 8F configuration are carried out to change this On point, the bicycle parking device 200 of embodiment is different from the bicycle parking device 100 of basic structure example.

As shown in Figure 28~Figure 30, Figure 41, auxiliary gas spring 81 is with being carried out to bottom chassis 20 (the second lifting unit) Be configured to the split of gas spring 80 of traction other gas springs of the inside of pillar 3, its substitute constant force spring 1 and to top Chassis 10 (the first lifting unit) is drawn.Identical with gas spring 80, auxiliary gas spring 81 possesses assistant cylinder 81S, auxiliary Piston 81P, auxiliary piston rod 81R, auxiliary restriction 81F and cylinder side installation portion 81BS, bar side installation portion 81BR etc. are helped, Working fluid is sealed with two rooms (rostral confined chamber 811 and bar side confined chamber 812) inside assistant cylinder 81S (here For nitrogen).Moreover, auxiliary piston rod 81R has extrusion pressure on prolonging direction (lower section in Figure 28, Figure 29, Figure 41) all the time PF₁(gas reaction force).

In Figure 42 and Figure 43, when assistant cylinder 81S internal diameter is set into D₁, auxiliary piston rod 81R diameter set For d₁, the area (compression area) of the compression face of auxiliary piston 81P rostral (that is, cylinder side installation portion 81BS sides) is set to AH₁, the area (compression area) of the compression face of auxiliary piston 81P bar side (that is, bar side installation portion 81BR sides) is set to AR₁When, It is expressed as follows.

(5)AH₁=π D₁ ²/4

(6)AR₁=AH₁-πd₁ ²/ 4=π (D₁+d₁)(D₁-d₁)/4

Now, compression area ratio r₁It is expressed as.

(7)r₁=AR₁/AH₁=(D₁+d₁)(D₁-d₁)/D₁ ²

Moreover, in the present embodiment, by the compression area ratio r₁It is adjusted to meet following relation.

(8)0.77≤r₁≤0.92

So, by the way that the compression area ratio r of gas spring 81 will be aided in₁It is set to larger and relatively reduces in piston rod Protrusion side and being retracted into caused by side lag, thus, it is possible to mitigate jiffy stand uplifted side (that is, the piston rod under complete vehicle curb condition Prominent side) and jiffy stand decline the operating physical force of the user needed for side (that is, piston rod is retracted into side), so as to realize jiffy stand 11 Lifting when operational raising.

In addition, in the present embodiment, using D₁=27mm, d₁=10mm, r₁=0.863 value.Wherein, on compression face Product ratio r₁, it is preferably in 0.80≤r₁≤ 0.89 scope, is more preferably in 0.82≤r₁≤ 0.87 scope.If more than upper State higher limit, it is likely that flexing is produced in piston rod, on the other hand, if being less than lower limit, when particularly jiffy stand rises Operating physical force become big, People is possible to produce obstacle to shut-down operation of bicycle of powered dynamic auxiliary device etc..

In addition, in this embodiment, gas spring 80 employs the gas spring of identical size with auxiliary gas spring 81, In Figure 38~Figure 40, D₀=D₁=27mm, d₀=d₁=10mm.Therefore, the compression area ratio r of gas spring 80₀For r₀= r₁=0.863.

In addition, as shown in Figure 38~Figure 40, in the present embodiment, in mathematical expression 1, D₀=27mm, d₀=10mm, n=3, k₁=k₂=0.6mm, k₃=1.0mm, and the gas for employing gas spring 80 averagely circulates index x₀=8.41 value.

So, in addition to piston 80P throttling hole number n, (the reference picture 38~figure of gas spring 80 in the present embodiment 40) there is the construction general with the gas spring 80 (reference picture 27A~Figure 27 C) in basic structure example.Thus, in the present embodiment Gas spring 80 action (Figure 38) it is identical with the action (Figure 27 A) of the gas spring 80 in basic structure example, so as to by its Describe in detail and omit.

Next, the auxiliary gas spring 81 (41~Figure 43 of reference picture) in the present embodiment has and gas as described above The roughly the same construction of spring 80 (38~Figure 40 of reference picture).Wherein, it is sealed with the auxiliary gas spring 81 shown in Figure 41 More than the closing oily BO of oily SO buffering enclosed in the gas spring 80 shown in Figure 38.
