As shown in Figures 4 and 5, operating portion 20 has main body cover 21, is accommodated with: button 22 in this main body cover 21; The maintaining body of this button 22 is kept according to the mode that can switch to mode of operation and off working state; With the rope yarn trailer coupling of traction rope yarn 40.Button 22 is installed in the top of main body cover 21, and the jack-up spring 28 being configured supporting device described later supported.More specifically, as shown in the exploded drawings of Fig. 5, be configured with jack-up spring 28 in the substantial middle of main body cover 21 bottom surface, button supporting member 29 is set thereon, configuration button 22 on this supporting member 29.
Rope yarn trailer coupling, in the bottom of main body cover 21, is installed in the left and right sides of jack-up spring 28.That is, rope yarn trailer coupling is made up of following components: the rope yarn traction element 23 being formed with tooth bar 23a on top; Miniature gears 24; The drive disk assembly 25 forming tooth bar 25a in bottom is formed.Clip miniature gears 24, according to the mode of occlusion mutually, at outside configuration rope yarn traction element 23, at inner side configuration drive disk assembly 25.Rope yarn traction element 23 is formed with recess 23b in bottom, in this recess 23b, install rope yarn 40.Drive disk assembly 25 forms spring support 25b on top, and spring support 25b configures rope yarn haulage adjustment spring (absorbing mechanism) 26.Button supporting member 29 is formed two recess 29a, and each drive disk assembly 25 is mounted by being fastened in each recess 29a below the spring support 25b of drive disk assembly 25.That is, button 22 is provided with two drive disk assemblies 25, between button 22 and drive disk assembly 25, configures rope yarn haulage adjustment spring 26.
Maintaining body is made up of following components: the pin 27 installed in the central authorities of button supporting member 29; The cam 30 engaged on main body cover 21 and with pin 27 is installed in the mode that can slide; With the jack-up spring 28 of the substantial middle configuration in main body cover 21 bottom surface.Cam 30 is formed the obcordate groove 31 engaged with pin 27, pin 27 is provided with locking spring 32.Locking spring 32 has pin 27 is pushed to obtain the elastic force on direction to cam 30.In groove 31, be formed with step, pin 27 be formed as cannot by the elastic force of locking spring 32 on on step, and to move to certain orientation all the time in obcordate groove 31.According to this structure, if be pressed into button 22, then pin 27 declines along the groove 31 of cam 30, and stops at assigned position 31a.That is, button 22 is maintained at the state of being pressed into.If again press button 22, then pin 27 leaves assigned position 31a, and button 22 rises and turns back to initial condition.That is, disarm state is become.
Below, also with reference to Fig. 6 to Fig. 8, the action of the suitcase of above-mentioned structure is described.When Fig. 6 represents that drg is closed, Fig. 7 represent open drg and rope yarn haulage minimum time, Fig. 8 represent open drg and rope yarn haulage maximum time operating portion and operating member.
Fig. 6 is initial condition, represents state when drg is closed.Now, button 22 rises, and is the state that brake plate 15 does not contact with rim 6.In order to operational brake in this condition, as shown in Fig. 7 (a), be pressed into button 22.Now, utilize rope yarn haulage to adjust the recuperability (antagonistic force) of spring 26, rope yarn haulage adjustment spring 26 roughly presses drive disk assembly 25 according to natural length, and like this, drive disk assembly 25 declines.As a result, the miniature gears 24 be engaged with drive disk assembly 25 rotates, and meanwhile, the rope yarn traction element 23 be engaged with miniature gears 24 rises, and rope yarn 40 is pulled.If rope yarn traction element 23 draws rope yarn 40, then as shown in Fig. 7 (b), connecting member 12 rotates, and presses the upper end of action axle 14.Like this, brake plate 15 presses the rim 6 of castor 5, drg action.That is, rim 6 becomes rotation halted state.
Meanwhile, along with pressing of button 22, the pin 27 be installed in button supporting member 29 also declines along the groove 31 of cam 30.Now, pin 27 vertically declines along with button 22, and because cam 30 is installed on main body cover 21 according to the mode that can slide, therefore, cam 30 slides, and pin 27 can decline reposefully along being formed as obcordate groove 31.The button 22 be pressed utilizes the elastic force pressure of jack-up spring 28 to rise, but now, pin 27 engages with the assigned position 31a of cam 30.As a result, button 22 is remained on by cam 30 and pin 27 state of being pressed into.That is, as mentioned above, keep the mode of operation of drg, suitcase becomes resistance to movement state.If be again pressed into button 22 in this condition, then pin 27 will depart from from the assigned position 31a of cam 30, and utilize the elastic force pressure of jack-up spring 28, button 22 returns initial position.Now, the traction of rope yarn 40 is removed, and therefore, utilize drg to remove the elastic force of spring 16, brake plate 15 departs from from rim 6.So suitcase just becomes can the state of movement.
Below, the service condition of rope yarn haulage adjustment spring 26 is described.Rope yarn haulage adjustment spring 26 is arranged in the following manner, that is, in the generation situation such as the wearing and tearing of manufacturing errors, rim and brake plate, the elongation of rope yarn also can with certain pressing force by brake plate 15 by being pressed on rim 6.In order to keep the state making brake operation, pin 27 must arrive the assigned position 31a of cam 30, and button 22 only must be pressed into the regulation amount of being pressed into arriving assigned position 31a.When there is no the problems such as rim wearing and tearing, as shown in Figure 7, brake plate 15 contact with rim 6 and make to become rotate halted state time, no longer excessive traction rope yarn 40, but, be pressed into due to button 22 amount of being pressed into not reaching regulation, therefore, pin 27 can not arrive the assigned position 31a of cam 30, cannot keep drg.Therefore, in the case, rope yarn haulage adjustment spring 26 is used to absorb the residue amount of being pressed into of the regulation amount of being pressed into of button 22.That is, if continue to be pressed into button 22 when brake plate 15 contacts rim 6 and makes it become and rotate halted state, so, rope yarn haulage adjustment spring 26 will shrink, and can be pressed into the be pressed into amount of button 22 to regulation.So just can keep the mode of operation of drg.
On the other hand, if there is the problems such as rim wearing and tearing because of the use of manufacturing errors and suitcase, so, rope yarn 40 is pulled until brake plate 15 contacts with rim 6, and the amount that rope yarn haulage adjustment spring 26 absorbs reduces automatically.Finally as shown in Figure 8, rope yarn haulage adjustment spring 26 can not shrink substantially, and rope yarn traction element 23 only draws the regulation amount of being pressed into of button 22.Like this, because manufacturing errors castor is not installed in design attitude, or because of the wearing and tearing of rim and drg, the distance between rim and drg is larger than designed distance, or, because of the elongation of rope yarn 40, rope yarn 40 cannot be drawn according to designing requirement when the amount of being pressed into specified, now, the uptake (amount of contraction) of rope yarn haulage adjustment spring 26 reduces, and so also can apply the pressing force specified on rim 6.
As mentioned above, according to the present embodiment, operating portion 20 is arranged on the top of chest main body 1, is namely arranged near handle, therefore, without the need to doing by foot operation or bending over manual manipulation, and so just can operational brake like a cork.In addition, operating portion 20 is equipped with button 22, by being pressed into button 22 shirtsleeve operation like this, just can switch removable state and resistance to movement state, therefore, it is possible to operate easily.And operating portion 20 has rope yarn haulage adjustment spring 26, when the rope yarn haulage of rope yarn trailer coupling traction rope yarn 40 is less than the regulation amount of being pressed into of button 22, rope yarn haulage adjustment spring 26 can the regulation amount of being pressed into of absorption operation button 22.Result, when causing producing error with design originally because of reasons such as the wearing and tearing of manufacturing errors, rim and drg, the elongations of rope yarn, also the pressing force equal with pressing force required in design originally can be obtained, and resistance to movement state can be reliably become.
Above, an embodiment of the invention are illustrated, but the present invention is not limited to above-mentioned embodiment, only otherwise depart from its aim, can various change be carried out.Such as, in the above-described embodiment, operating portion 20 is configured in the top of chest main body 1, but, as long as do not bend over, by hand just operable scope, the optional position of chest main body 1 can be configured in.
In the above-described embodiment, control as follows, utilize pin 27 and cam 30 that action button 22 is switched to mode of operation and off working state, but as shown in Figure 9, be equipped with disengage button 51 on the side of button 22, can control with ratchet.More specifically, at button supporting member 29, rack member 52 is installed, on main body cover 21, according to can pivotally install be made up of miniature gears 53a and gear 53b pivot parts 53.Disengage button 51 is installed retainer 54, and retainer 54 is according to can pivotally be installed on main body cover 21.Rack member 52 and miniature gears 53a are engaged, and retainer 54 and gear 53b are engaged.Now, ratchet is formed by retainer 54 and gear 53b.If press the button 22, so, rack member 52 declines, and miniature gears 53a rotates.Meanwhile, gear 53b rotates, and the position be engaged with retainer 54 changes, and button 22 is maintained at the state be pressed into.Then, if be pressed into disengage button 51, so, the occlusion of retainer 54 and gear 53b is removed, and utilizes the elastic force pressure of jack-up spring 28, and button 22 returns initial position.
According to this structure, in the position that button 22 is pressed, button 22 is kept in this condition, therefore, it is possible to stop button 22 in arbitrary position.That is, button 22 is stopped under the state that can contact with rim 6 at brake component 13, and, under the state continuing to be pressed into button 22 from this state, also can stop button 22.If brake component 13 continues to be pressed into after contacting with rim 6, so, rope yarn haulage adjustment spring (pressing mechanism) 26 will be shunk (elastic deformation) thus be pressed into, now, the antagonistic force (recuperability) produced from rope yarn haulage adjustment spring 26 is continued to be applied to rim 6.So be pressed into button 22, the antagonistic force of rope yarn haulage adjustment spring 26 is larger, therefore, it is possible to increase brake component 13 is applied to the power on rim 6.As a result, according to the amount of being pressed into of button 22, can the braking effect of regulating brake.
In the above-described embodiment, rope yarn haulage adjustment spring 26 is equipped with in each drive disk assembly 25, adjust the haulage of rope yarn 40 respectively, as shown in Figure 10, only be equipped with a rope yarn haulage adjustment spring 61, when rope yarn haulage is different, also can adjust the haulage of rope yarn respectively accordingly.More specifically, at the substantial middle configuration spring support 62 of button supporting member 29, in spring support 62, rope yarn haulage adjustment spring 61 is configured.According to can pivotally mounted movable transmission capacity adjustment component 63 in spring support 62, in Movement transmit amount adjustment component 63, each drive disk assembly 64 be installed.When the rope yarn haulage of left and right is different, Movement transmit amount adjustment component 63 pivots, and absorbs the difference of the rope yarn haulage of left and right.
In addition, in the above-described embodiment, rope yarn haulage adjustment spring 26 employs coil spring, but as shown in FIG. 11 and 12, rope yarn haulage adjustment spring 71 can use leaf spring.Represent the example employing the operating portion 20 of leaf spring below.More specifically, rope yarn haulage adjustment spring 71 front is seen in U-shaped, and its two ends bend outward.Operating portion 20 has main body cover 21, according to the substantial middle mounting and adjusting spring perch 72 of the mode that can rotate at this main body cover 21.The bending two ends of rope yarn haulage adjustment spring 71 are hooked on this adjustment spring perch 72.In addition, adjust spring perch 72 and be formed with the support 72a at one end installing rope yarn traction element 73.The upper end of rope yarn traction element 73 can engage with the support 72a of adjustment spring perch 72, and rope yarn 40 can be supported in lower end.Be integrally formed with front in the large central lower end of adjustment spring perch 72 and see jack-up spring 74 in C word shape.When adopt install in this way time, rope yarn haulage adjustment spring 71 one end clamp adjustment spring perch 72 S. A., extend to the end with the end opposite side of installing rope yarn traction element 73 always.Rope yarn haulage adjustment spring 71, adjustment spring perch 72, rope yarn traction element 73 and jack-up spring 74 also have one group, under the state of reversing about making it, when it is observed in front, are installed in main body cover 21 according to the mode forward lapped.Now, jack-up spring 74 is also installed in the lower end of main body cover 21.The bottom of button 75 tilts in outside downwards from central authorities, and when it is observed in front, tilts in the opposite direction in front and back.The lower end of this button 75 is by the end of placing at rope yarn haulage adjustment spring 71.Button 75 does not represent in mount pin 27, figure, main body cover 21 is installed cam 30.
Use Figure 13, the service condition of above-mentioned rope yarn haulage adjustment spring 71 is described.Figure 13 (a) represent that drg is opened and rope yarn haulage is minimum time, Figure 13 (b) represent that drg is opened and rope yarn haulage is maximum time the front view of operating portion.If be pressed into button 75, so, rope yarn haulage adjustment spring 71 will be pressed in the lower end of button 75, and therefore, adjustment spring perch 72 starts to rotate.Like this, rope yarn traction element 73 is pulled up, and meanwhile, rope yarn 40 is pulled.The action of operating member 10 is now identical with during use coil spring.When not having the problems such as rim wearing and tearing, rope yarn haulage adjustment spring 71 must shrink.In the case, as shown in Figure 13 (a), U-shaped peristome narrows, and leaf spring becomes the state of contraction.On the other hand, if there is the problems such as rim wearing and tearing because of the use of manufacturing errors and suitcase, so, the amount that rope yarn haulage adjustment spring 71 absorbs will correspondingly reduce automatically.Final as shown in Figure 13 (b), rope yarn haulage adjustment spring 71 can not shrink substantially, and rope yarn traction element 73 is only pulled up the regulation amount of being pressed into of button 75.
Owing to having this structure, therefore, even if when producing error because of reasons such as the wearing and tearing of manufacturing errors, rim and drg, the elongations of rope yarn with design originally, also can obtain with design originally in the equal pressing force of required pressing force.In addition, the number of parts used in operating portion 20 can also be reduced.Like this, operating portion 20 will lighten, and can not only realize the lightweight of whole suitcase, and can reduce manufacturing cost.
In the above-described embodiment, as absorbing mechanism, rope yarn haulage adjustment spring 26 is provided with in operating portion 20, and have adjusted the difference of the amount of being pressed into of button 22 and the haulage of rope yarn 40, but, the drg amount of being pressed into adjustment spring (absorbing mechanism) 81 of the difference adjusting the amount of being pressed into of brake component 13 and the amount of being pressed into of button 22 of being used for also can be set in operating member 10.Specifically, the connecting member 80 arranged in operating member 10 adjusts spring 81 by the drg amount of being pressed into and main body 82 is formed.As shown in Figure 14 and Figure 15, drg amount of movement adjustment spring 81 is formed as front and sees leaf spring in U-shaped.Drg amount of movement adjustment spring 81 is according to can being installed in main body 82 along the mode that above-below direction is flexible.Same with above-mentioned embodiment, this connecting member 80 is installed in main body cover 11 according to the mode can rotated around horizontal shaft 12a.Arrange brake component 13 at the U-shaped peristome side 81a of the drg amount of being pressed into adjustment spring 81, another side 82a and rope yarn 40 link.If traction rope yarn 40, so, connecting member 80 will rotate, and brake component 13 is pressed into downwards.For the drg amount of the being pressed into adjustment spring 81 of this structure, when not having the problems such as rim wearing and tearing, the drg amount of being pressed into adjustment spring 81 must shrink, and shrinks in the mode making the opening of U-shaped narrow.On the other hand, if there is the problems such as rim wearing and tearing because of the use of manufacturing errors and suitcase, so, the amount that the drg amount of being pressed into adjustment spring 81 absorbs will correspondingly reduce automatically.Finally, the drg amount of being pressed into adjustment spring 81 can not shrink substantially, and brake component 13 is only pressed into the regulation amount of being pressed into of button 22.In addition, in the case, operating portion 20 need not arrange rope yarn haulage adjustment spring 26, as long as be equipped with button 22, maintaining body and rope yarn trailer coupling.Like this, not in operating portion 20, absorbing mechanism is set in operating member 10, the structure in the portion 20 that can not only simplify the operation like this, and, because the absorbing mechanism 81 of operating member 10 is also without the need to adopting complicated structure, therefore, it is possible to easily with less part manufacture.
