Description

The basic framework that has the bag of castor and be used for this bag

Technical field

The present invention relates to the basic framework that has the bag of castor and constitute it, particularly have the bag of the handle that can stretch up and down.

Background technology

The bag that has castor that possesses the handle of pulling out is freely developed and is widely used.In the bag of this structure, great majority are for taking into to the size of aircraft degree, or more more than the bag of its big slightly type.This structure for example wrap in that the U.S. speciallys permit No. 4995487 specification, special fair 4-76686 communique, the real clear 57-179824 communique and real opened is opened record to some extent in the clear 63-131634 communique.The bag of in these communiques, putting down in writing is as shown in Figure 1, and the side in the bottom surface is provided with two castors 41.Opposition side at castor 41 is fixed with short pin 42.Erect if will wrap vertically, then castor 41 contacts on the ground with pin 42.Under this state, because 42 contacts of non-rotary pin are vertically supported oneself so wrap under the state that does not move.And then, move it for the tractive bag, be provided with handle 43 in the above, so that it can be pulled out.Handle 43 since under the state that bag is tilted tractive move, so be located at a side identical with castor 41.

The bag of this structure is as shown in Figure 1, can make that bag tilts, tractive handle 43 and moving.If bag tilts, then castor 41 contacts on the ground, pin 42 leaves from ground.If tractive handle 43 under this state, then castor 41 rotates and can move like a cork.But, move like this wrap in the aircraft such narrow place or there is the situation that can not use castor 41 in the place that mixes.This is because if through castor 41 walking, narrow path between horizontal wide the broadening of bag then, attending a banquet in machine or the place that mixes can not freely be moved.If no longer can use castor 41, then need to wrap to move with portable.When moving with portable, can move to the direction of representing with the arrow A of Fig. 1, can not broaden so that horizontal stroke is wide.

The bag that has castor wraps and easy-to-use structure in order to move heavily easily, like a dream.This is because even bag is heavier, also can move like a cork through castor.The present inventor has developed the bag (opening flat 10-117829 communique with reference to the spy) of structure shown in Figure 2 in order to eliminate such shortcoming.The bag of this figure is installed in castor 341 on the bottom surface of box main body 344.Castor 341 is located on four jiaos of bottom surface, so that box main body 344 can be supported oneself with vertical position.The hand grip portion 343A of handle 343 is positioned at the central authorities about it above box main body 344.Bag that kind shown in the Bao Buhui image pattern 1 of this structure moves bag obliquely.Bag is moved to the direction shown in the arrow of Fig. 2 with the posture of vertically erectting.If the direction to shown in the arrow moves, then can make horizontal wide narrowing down and move.Therefore, having can be in machine or the strong point that moves easily of the place that mixes.And then if in 4 castors 341, use the universal caster wheel that can move to direction freely, then bag can move to direction freely with vertical posture.In the bag of vertical position, the weight of bag can not act on the handle 343.Therefore, even bag is very heavy, also only just can move like a cork through pushing.

The bag of this structure can push the hand grip portion of handle, brisk and move like a dream through 4 castors.But the bag of this structure is owing to be installed in central authorities with handle, so shown in the cutaway view of Fig. 3, need be with the expansion link 345 of handle 343 internal fixation at box main body 344.Expansion link 345 for hand grip portion 343A is provided in box main body 344 about central authorities, connect box main body 344 about, be that the state of the central authorities of thickness direction is fixed down.In the bag of this structure, expansion link 345 becomes obstacle, is difficult to use effectively the inside of box main body 344.

The present inventor is a purpose to solve these shortcomings etc., has developed the bag (spy opens flat 10-137022 communique) of Fig. 4 record.

This bag is located at four bights, bottom surface of box main body 444 with castor 441, and expansion link 445 is fixed on the side of this box main body 444.Expansion link 445 is the structures that can handle 443 be pulled out to the top, is provided with hand grip portion 443A in the upper end.Expansion link 445 is down crooked by the state of pulling out from box main body 444 so that hand grip portion 443A be positioned at box main body 444 top about central authorities.

The bag of this structure is owing to be fixed on sidepiece with expansion link, so have the strong point that the inside that can make the bag main body deepens.But the bag of this structure is owing to being fixed on expansion link on the bag main body, so need make the bag main body become solid structure.This is because expansion link is supported oneself on the bag main body.The bag of this structure is not such tractive expansion link as shown in Figure 1 and moving, but as walking stick, when using as pedestrian's supporting, forwards pushes and the bag main body is moved, so even the solid structure that requires pushing yet can not fall down.Therefore, can make expansion link stand in the structure on the bag main body certainly in order to make, the mounting portion that needs to wrap main body and expansion link is strengthened securely solidly.Therefore, have the structure of bag main body to become shortcoming that complicacy and cost of manufacture significantly uprise.In addition, wrapping main body in addition is difficult to not reduce accommodation space and strengthens the shortcoming for solid structure.

The present inventor has developed bag shown in Figure 5 in order to solve this shortcoming.These four bights that wrap in the bottom surface are provided with and can on the basic framework 51 of the castor 56 of the walking of direction freely, bag main body 53 be installed removably.Basic framework 51 possesses and carrying of bag main body 53 is installed in the above puts platform 52, to pull out freely and have the expansion link 55 of handle 54 in the upper end and make this expansion link 55 remain on the block (not shown) of extended position and punctured position to the top.Carry and to put platform 52 and be provided with castor 56 in four bights.Expansion link 55 is fixed on and carries the side put platform 52, so that it prolongs and support oneself to the top.Bag main body 53 carry put platform 52 above and be assemblied on the side of expansion link 55, and be attached on the basic framework 51.

The bag of this structure can not be as in the past, stop expansion links 55 to fall down by bag main body 53.Therefore, basic framework 51 need be attached at expansion link 55 to carry with the solid structure that does not fall down securely and put on the platform 52.In order to realize this point, basic framework 51 is fixed on expansion link 55 to carry and puts on the bight of platform 52, and expansion link 55 usefulness reinforced walls 58 are strengthened.Reinforced wall 58 is along carrying the wall that two ora terminalis put platform 52 are provided with, and expansion link 55 is put platform 52 and linked with carrying, and expansion link 55 is attached to carry puts on the platform 52, so that it can not fall down.This basic framework 51 is equipped with bag main body 53 on the part of being surrounded by expansion link 55 and reinforced wall 58.Carry and to put platform 52 and reinforced wall 58 through the making that is shaped integratedly of light metals such as plastics or aluminium.

The bag of this structure is attached at expansion link to carry through reinforced wall and puts on the platform so that it can not fall down.But, because reinforced wall is installed between the reinforced wall at two ends so need to wrap main body along carrying the two ora terminalis settings of putting platform.This is because the width of bag main body has been confirmed at the interval of a pair of reinforced wall, is carrying the size of putting the bag on the platform and design etc. so limit to carry to put.

The present inventor has also developed bag shown in Figure 6 in order to address this problem.This bag is same with the bag of Fig. 5, possesses basic framework 61 and bag main body 63 with castor 66.Be the formation position of reinforced wall 68 with the difference of the bag of Fig. 5, the reinforced wall 68 of the bag of Fig. 6 is located at carries the lower side of putting platform 62.For this reinforced wall 68, use describes as Fig. 7 of the face upwarding stereogram of basic framework 61.Reinforced wall 68 is configured between the castor 66 that is located on four jiaos that carry the bottom surface side put platform 62, and will horizontal reinforced wall 68A with reinforced wall 68B binding longitudinally and constitute.In addition, reinforced wall 68 be projected into carry put platform 62 below, its projecting height is lower than the height of castor 66.

Like this reinforced wall 68 is provided with to carrying the lower side of putting platform 62 highlightedly, can basic framework 61 be made solid structure.As a result, can omit the reinforced wall of carrying the upper face side put platform 62, so no longer include the restriction on the space carrying the upper face side of putting platform 62, the range of choice of carrying the bag main body 63 of putting enlarges.

But,,, need to avoid the installation site of castor 66 and be provided with so be located at the reinforced wall 68 of carrying the bottom surface side of putting platform 62 equally owing to be provided with castor 66 carrying on four jiaos of the bottom surface put platform 62 according to the bag of Fig. 6.Thereby, become and be configured between the castor 66, but this has also limited and has linked with reinforced wall 68 and to the position that is provided with of carrying the carrying cylinder 67 that the top of putting platform 62 extends.And then, the position of also having limited the handle 64 of expansion link 65 of inserting logical carrying cylinder 67 and linking and the upper end that is located at expansion link 65.So, under the less situation in the interval of castor 66, make the spacing L that leaves of expansion link 65 become littler based on the reinforced wall 68 that is arranged on 66 of this castors, thereby the length of handle 64 also shortens.

Controlling the short handle 64 in zone is difficult to hold.Become the narrow scope application of force to the side of bag, it is difficult that the control of bag becomes.As a result, be difficult for promoting bag, so be difficult to control the direction of travel of bag.In addition, also might destruction of balance and make bag become to fall down easily.

Summary of the invention

The present invention is that purpose is developed with this shortcoming of further solution, an object of the present invention is to provide a kind of mobile bag that has castor of control easily and basic framework that constitutes it of becoming of expansion link being strengthened and made bag.

The specific embodiment

Below be described in detail the bag with castor of the present invention and with above that basic framework, but embodiment 1～3rd, expression reference example of the present invention, embodiments of the invention are represented in embodiment 4.

(embodiment 1)

The exploded perspective view of the bag that has castor 100 (following also have singly the situation that is recited as " bag ") of the relevant embodiment 1 of expression in Fig. 8.In addition, expression will be wrapped main body 3 lift-launchs at the side view that carries the state on the face 2 of putting in Fig. 9.This bag 100 that has a castor mainly is made up of bag main body 3 and the basic framework 1 that can carry this bag main body 3.Basic framework 1 has the face 2 of putting that carries that carries bag main body 3 removably.On four bights of carrying the bottom surface side put face 2, being provided with can be to the castor 6 of the oscillating type of direction walking freely.In addition, basic framework 1 has and puts the upwards direction carrying cylinder 7 of the upright hollow form of establishing generally perpendicularly of face 2 from this year in rectangular-shaped at least a portion zone of carrying a side of putting face 2.Aerial in this carrying cylinder 7, insert and be connected with the expansion link 5 that can stretch up and down, and expansion link 5 and carrying cylinder 7 bindings, so that it is supported oneself with the posture that stretches to the top.In addition, basic framework 1 has and makes expansion link 5 stop at the block 15 (with reference to Figure 20) of extended position.And then, being provided with handle 4 in the upper end of expansion link 5, the bearer can control this handle 4 and will wrap 100 directions to hope and move.And details is narrated in the back, but this bag 100 has the strong point that can change bag main body 3 simply.Various bag main bodys 3 are being carried 1 last time of basic framework, will wrap main body 3 and place to carry and put on the face 2, making bag main body 3 fixing under the posture of the side of expansion link 5.

In addition, in the example of Fig. 8, Fig. 9, making and carrying the flat shape of putting face 2 is rectangle.Putting face 2 this year is fixed on each 1 carrying cylinder 7 on the one-sided two ends as a rectangular long limit.Carrying cylinder 7 be from carry put face 2 above towards the posture of top, promptly extend along carrying the roughly normal direction of putting face 2, put face 2 and be shaped integratedly and be provided with carrying.That is, carrying cylinder 7 is more outstanding than carrying the last face up of putting face 2, and is not projected into bottom surface side.Thus, the lower end that does not have carrying cylinder 7 collides the situation of walking the road surface and hindering the walking of bag 100, also can successfully move even have the walking road surface of some steps.

In addition, put on the table back side of face 2 because castor 6 is located at respectively to carry with carrying cylinder 7 individually, it forms the situation of position so there is not interdependence, can on each face, position freely.That is, do not put on the same one side of face 2, carrying cylinder 7 is not set so need not avoid the affixed position of castor 6 because castor 6 is arranged on to carry with carrying cylinder 7.In the example of Fig. 8, Fig. 9, carrying cylinder 7 and castor 6 all are positioned at and carry the bight of putting face 2, and in other words, castor 6 is installed along the roughly vertical direction of carrying cylinder 7.Thus, the power that is applied on the handle 4 is transmitted to castor 6 from carrying cylinder 7 point-blank, so can easily control the moving direction of castor, the stability of bag increases.In addition, can alleviate the mobile needed power of bag, be preferred.

In addition, Figure 10 puts the stereogram of face 2 sides when observing basic framework 1 from carrying.Shown in figure 10, basic framework 1 is being put the holding up in the portion of upwards direction is generally perpendicularly outstanding above the face 2 carrying cylinder 7 from carrying, possess with carrying cylinder 7 with carry the reinforced wall 8 that the face of putting 2 links.This reinforced wall 8 only is attached at has carried the binding put on the face 2 on the mutually same side of carrying cylinder 7, and carrying cylinder 7 is positioned at roughly with one side with reinforced wall 8.That is, both of carrying cylinder 7 and reinforced wall 8 are configured in the face of the side direction top quadrature that carries the face of putting, and are in the posture that the thickness separately of carrying cylinder 7 and reinforced wall 8 links each other.More particularly, roughly be formed with reinforced wall 8 on the position in the bight of quadrature and the engaging zones that constitutes fill carrying the face of putting 2 and carrying cylinder 7.In addition, in the example of Figure 10, two carrying cylinders 7 separate abreast, in the reinforced wall 8 therebetween distances.That is, reinforced wall 8 is made as from the two ends of carrying the side put face 2 between upright two carrying cylinders 7 establishing in top, puts in the rectangular-shaped bar frame 29 that face 2 and carrying cylinder 7 and expansion link 5 surround by carrying.In addition, from the viewpoint of intensity, this reinforced wall 8 is preferably put face 2 and carrying cylinder 7 is shaped integratedly with carrying.

And then reinforced wall 8 is shown in figure 10, can be located at 1 position or a plurality of position in the bight of bar frame 29.The shape of the bight that being shaped as of the reinforced wall 8 under this situation can be filled up bar frame 29 at least and the area that can the roughly quadrature and the adjacent limit of bar frame 29 be linked in fact each other.Particularly; As shown in the figure; The shape in bight that can depending post frame 29 and make triangular shape, in addition, can make polygon-shaped, or make right angle avris is wavy line or circular-arc etc. curve or has rugged different shape such as step-like in bight.In addition, also can make in bar frame 29, with opposed carrying cylinder 7 bridge company's junction configuration each other.In addition, reinforced wall 8 also can keep whole shape and with inside with point-like opening etc., carry out lightweight.

Through possessing reinforced wall 8 like this, the intensity of carrying cylinder 7 and expansion link 5 increases.Particularly, through the bight of the rise part of carrying cylinder 7, bar frame 29 is strengthened, bar frame 29 is more stable, can prevent the distortion of skeleton.That is, the horizontal direction of the expansion link 5 of pushing, be that the intensity of the left and right directions of Figure 10 increases.

In addition, carrying cylinder 7 possesses to the outstanding reinforcement base portion 34 of the thickness direction of reinforced wall 8.Figure 11 is the side view from the basic framework 1 of the Fig. 8 of side observation in the vicinity.Shown in figure 11, strengthen base portion 34 on the rise part of carrying cylinder 7, from bar frame 29 to foreign side with vertical direction, promptly form highlightedly to the back side of basic framework 1 direction (Figure 11 right-hand to).Through like this, the diameter of the rise part of carrying cylinder 7 is increased, carrying cylinder 7 is more firmly constituted, so, can stably support the expansion link 5 that is attached in the carrying cylinder 7.Reinforcement base portion 34 and above-mentioned reinforced wall 8 are same, and be from the viewpoint of intensity, preferably integrally formed with carrying cylinder 7.

In the example of Figure 11, carrying cylinder 7 has strengthens base portion 34, and in addition, this reinforcement base portion 34 is located in the whole zone of vertical direction of carrying cylinder 7.And then the diameter of carrying cylinder 7 is put face 2 and becomes big along with approaching to carry, that is, strengthen base portion 34 along with make towards the below outstanding quantitative change from carrying cylinder 7 big, carrying cylinder 7 is more slightly constituted.In the example of the reinforcement base portion 34 of Figure 11, its outstanding shape forms level and smooth inclination or curved surface shape, but outstanding shape and form the zone and be not limited to this.

For example, in carrying cylinder shown in Figure 12 7, made column above it with identical diameter.Strengthen base portion 34 from the length direction of carrying cylinder 7 put face 2 sides to carrying midway, outstanding and form step-like to the back side of basic framework 1 direction.In addition, the shape of the reinforcement base portion 34 of Figure 12 constitutes, and puts face 2 sides along with approaching to carry, and the diameter of strengthening base portion 34 increases gradually.

On the other hand, in the example of carrying cylinder shown in Figure 13 7, in the outstanding shape of strengthening base portion 34, its diameter roughly is certain, and promptly the rear side of carrying cylinder 7 is being strengthened base portion 34 with step-like outstanding.In Figure 12 and Figure 13, be provided with single step-like, should the zone as strengthening base portion 34, step-like quantity also can be a plurality of, and the diameter of strengthening base portion 34 also can be roughly certain or make the below become big structure.Like this, through making reinforcement base portion 34 outstanding, can not be provided with to carrying the ledge of putting face 2 sides carrying cylinder 7 and expansion link 5 are strengthened to the back side of basic framework 1 direction.That is, the intensity of the fore-and-aft direction of expansion link 5 (left and right directions of Figure 11～Figure 13) uprises.

Through additional above-mentioned reinforced wall 8 in carrying cylinder 7 and strengthen base portion 34, can be with bar frame 29 along continuous straight runs and vertical direction, promptly all around direction is strengthened.The load of the bar frame of being strengthened 29 improves three-dimensionally, not only can prop up the load of contracting main body 3 or/and bearer, in addition, can also bring into play the auxiliary effect of walking effectively.In addition, can stably support oneself, so when stopping and walking, the possibility of toppling over all reduces significantly owing to wrap 100.

The basic framework 1 that possesses the face 2 of putting that carries, carrying cylinder 7, reinforced wall 8 and strengthen base portion 34 is shaped integral body integratedly by the light metal of plastics or aluminium etc. and makes.Thereby each position is linked in by the operation of plastics or shaped light metal each other.This basic framework 1 can make reinforced wall 8, strengthens base portion 34, carry the strength of connection grow separately of putting face 2 and carrying cylinder 7.But basic framework 1 of the present invention also can be formed separately each position the back, through fixing etc. the structure of bonding or screw each position fixed.In addition, the material of each parts of formation base framework 1 both can be identical also can be multiple, consider lightweight, intensity etc. and suitably decision.

In addition, the shape of expansion link 5 and carrying cylinder 7 is so long as can insert the structure in the hollow of leading to carrying cylinder 7 with expansion link 5, and its shape is not special to be limited.For example in the bag 100 of Fig. 8～Figure 11, carrying cylinder 7 has been made square tubular corresponding to the expansion link 5 of flat column.In addition, also can make combination cylindric and cylindraceous.That is, the peripheral shape of expansion link 5 is preferably similar with interior all shapes of the hollow of carrying cylinder 7.The expansion link 5 that is inserted in the carrying cylinder 7 is fixed on the carrying cylinder 7 through hold-down screw.But expansion link 5 also can insert and be adhesively fixed in the carrying cylinder 7, or link through the inserted structure that can not come off.Through this structure expansion link 5 is attached to and carries the structure put on the face 2 and can the very solid structure of expansion link 5 usefulness be fixed on and year put on the face 2.

As stated, the bag 100 of embodiment 1 is as the reinforcement of carrying cylinder 7 or/and expansion link 5, through reinforced wall 8 is set and strengthens base portion 34 and realize carrying the upper side of putting face 2.Thereby the strengthening part of reinforced wall 8 and reinforcement base portion 34 is not located at and carries the lower side of putting face 2, is not fixed in the installation site of carrying the castor 6 on the bottom surface of putting face 2 so specify.That is, can castor 6 be fixed on the position of hope.Particularly, the formation zone through making strengthening part for carrying cylinder 7 each other, shown in figure 10, carrying the barrier that can remove wall etc. on the left and right directions of putting face 2 fully.That is, the carrying to put in the zone and can reduce the restriction on the space of bag main body 3 as far as possible, so the range of choice of the bag main body 3 of carrying enlarges.And then, owing to put the coupling position that can set freely above the face 2 with carrying cylinder 7 carrying, thus the distance of leaving that can regulate carrying cylinder 7 according to the length of the handle 4 of easy gripping, the desirable location of realizing carrying cylinder 7.

In addition, Figure 14 A is the vertical view of observing from the top of basic framework 1, and in addition, Figure 14 B is the upward view of basic framework 1.Shown in figure 14, put on the bottom surface of face 2 carrying, be shaped integratedly and be provided with the deep floor 10 that extends in length and breadth through plastics or light metal.Put face 2 this year and can when making integral thinned, make solid structure through deep floor 10.And then, carry the face of putting and also can between the deep floor that is provided with in length and breadth, be provided with and put the through hole of face up/down perforation and make it lighter carrying.

(installation method of bag main body)

Below explanation will be wrapped main body 3 and will be installed to the method on the basic framework 1.Bag 100 shown in Figure 9 is put above the face 2, is equipped with bag main body 3 adjacent to expansion link 5 carrying.This bag 100 is the structure of installation kit main body 3 removably.But, also can bag main body 3 be fixed on the basic framework 1 not removablely.In addition, the size of bag main body 3 and material are not special limits.In the bag main body 3 of Fig. 9, the flexibility sheet is made and made.

At first, basic framework 1 is described.Figure 15 is the stereogram of basic framework 1.Shown in figure 15, expansion link 5 possesses guiding tube 5B and can be inserted in with coming in and going out pulls out bar 5A among this guiding tube 5B.And then, narration in detail in the back, but the bar 5A that pulls out among the figure possesses two sections zoom-out function, is made up of the bar 5Ab that pulls out that pulls out bar 5Aa and hypomere of epimere.

In addition, the basic framework 1 of Figure 15 have with the bearing of trend of expansion link 5 roughly the direction of quadrature (left and right directions of Figure 15) go up the connecting rod 11 of building bridge.This connecting rod 11 have to carrying put face 2 sides, be the outstanding link piece 13 of side direction in the vicinity of Figure 15.Connecting rod 11 is located at the upper end of guiding tube 5B, is formed with link piece 13 integratedly through plastics or light metal.In addition, link piece 13 is inserted among the insertion section 3B (with reference to Fig. 3) that is located at bag main body 3 to be formed in and to wrap on the opposed faces of main body 3 to the outstanding shape in top, links bag main body 3 so that it can not break away from.The insertion section 3B of bag main body 3 possesses the binding gap in lower opening, inserts link piece 13 and binding each other here.

In addition, the shaping position of link piece 13 is not limited on the connecting rod 11.For example also can be made as on the expansion link 5.For example, another link piece 13b of Figure 15 is located on the guiding tube 5B that constitutes expansion link 5.If on the guiding tube 5B; Then can shorten from carrying and put the distance of face 2 to link piece 13b; Thus; Even under the lower situation of the height that carries the bag main body 3 put, also can be in the bottom surface of bag main body 3 contact of firm ground put under the state above the face 2 carrying, will wrap main body 3 and basic framework 1 and stably install.In addition, the number that is provided with of link piece 13,13b does not limit especially.For example if single link piece, then can with bag main body 3 and basic framework 1 easily, or dismounting at short notice.Perhaps, if make the form that a plurality of link piece 13 are set with the interval of regulation along the vertical direction, then can in addition, in a bag main body 3, can regulate coupling position corresponding to the bag main body 3 of all size with basic framework 1.

(embodiment 2)

In addition, bag main body 3 is not limited to the above with the connect mechanism of basic framework 1.Another example of connect mechanism is described below as embodiment 2.Figure 16 is the exploded perspective view of the bag that has castor 300 of relevant embodiment 2.The bag 300 of Figure 16 is compared with the bag of embodiment 1 has only bag main body 3 different with the linking method of basic framework 1, is same about other structures.Thereby, give identical label and omit explanation for identical structure.

The bag main body 3 of relevant embodiment 2 is shown in figure 16, has the slotting passband 40 of opening along the vertical direction.Insert the handle 4 of basic framework 1 side from the below of this peristome, handle 4 is moved to the top, that is, expansion link 5 inserted to lead to insert in the passband 40.So, shown in figure 17, put in 3 years carrying of basic framework 1 in the bag main body and to put under the state on the face 2, can bag main body 3 is fixing with basic framework 1.In addition, when bag main body 3 is broken away from basic framework 1, rise, will insert and lead to the expansion link of inserting in the passband 40 5 and discharge and realize through making bag main body 3.Like this, insert the binding form of leading in the slotting logical portion that is located at bag main body 3 sides, easily dismounting bag main body 3 and basic framework 1 through making a part that makes the basic framework side.

Insert passband 40 and be located at the face side of bag main body 3.The A/F of inserting passband 40 can change variedly, but has the width that can insert through rod frame 29 at least, preferably makes to compare with bar frame 29 to have some degree more than needed.Thus, can bag main body 3 and basic framework 1 be linked easily and stably.In the example of Figure 16, promptly wrap the side of one side at least at the table back side of main body 3 at bag main body 3 and the face width quadrature, be formed with rectangular-shaped slotting passband 40.Insert passband 40 and preferably make integratedly, but be not limited to this, also can make and form independent parts, be installed to form on the bag main body 3 removably with bag main body 3 from the viewpoint of the simple degree made.Perhaps, also can in the opening of the above-below direction of inserting passband 40, make upside opening always, downside suitably opens and closes freely through setting tool etc.Thus, when only using, can the downside sealing of inserting passband 40 be used as the pocket that wraps main body 3 through bag main body 3.In addition, insert not special qualification of material of passband 40, also can be made as and wrap main body 3 identical materials or different materials and improve design.In addition, also can adopt telescopic material or added functional materials such as mar proof.

And then, also can make structure on every side through the part coiling basic framework 1 of bag main body 3.For example, a pair of billet sheet is set on the main body 3, put in 3 years carrying and put under the state on the face 2 will wrap main body, this billet sheet is wound up into expansion link 5 or year puts on the face 2 at bag.And then, the two ends of billet sheet are linked each other, it is fixing with basic framework 1 to wrap main body 3.Billet sheet connect mechanism each other is not special to be limited, and for example can enumerate button, hook, hook, pull stap (magic tape) (registration mark), band, bar, ring, fastener etc.In addition, connect mechanism both can be single, also can be with various connect mechanism combinations.

In addition, expansion link 5 is narrated in detail in the back, can under the flexible state of above-below direction, stop in the position of regulation.Basic framework 1 shown in the arrow of Figure 15, will pull out bar 5A pack into respect to guiding tube 5B take out between be provided with a plurality of stop positions.Push if for example will pull out bar 5A, then pull out bar 5A and be received in the guiding tube 5B of below, stop in minimum position.Figure 18 is the bag 300 that will wrap main body 3 and basic framework 1 binding with the connect mechanism of relevant embodiment 2, the states that expression further descends expansion link 5.Shown in figure 18,, under the posture that upper/lower positions stops, making basic framework 1 miniaturization and take at expansion link 5 along bag main body 3.That is, can make the whole size of bag 100 roughly the same with bag main body 3, the result can be worn at shoulder with the handle 46 of bag main body 3 or arm is first-class, will wrap 300 integral body and mention and carry.That is, can basic framework 1 and bag main body 3 be taken in carrying integratedly, even under the state that does not use castor 6, also can move bag 300.This on the road surface with step etc., be difficult for using in the environment of castor 6, will wrap 300, to pick up when carrying from the road surface be easily.Particularly; Shown in figure 18; Through in a pair of handle 46 that will wrap main body 3, lead to laterally between handle 4 and the connecting rod 11 from the inboard adjacent to the handle 46 of a side of expansion link 5, handle 46 can be involved in handle 4 from bottom to top and support, so carrying stably easily.

And then if expansion link 5 by elongation and mention handle 4, then carries the side of putting on the face 2 towards central bend, so that handle 4 off-centre from being fixed on shown in Fig. 8 to Fig. 9 or Figure 11 etc.As shown in the figure, expansion link 5 being fixed under the situation of carrying the right side of putting face 2, put the central authorities of face 2 in so-called year, be meant the center of left and right directions.The bag 100 of Fig. 9 carries the right side of putting face 2 owing to expansion link 5 is fixed on, thus if with expansion link 5 pull-ups, then make expansion link 5 bendings, so that handle 4 is eccentric towards the left side from carrying the right side of putting face 2.In other words, expansion link 5 is to making the outstanding laterally direction of central portion crooked, make the handle 4 that is pulled up eccentric to the direction that approaches central authorities from carrying the sidepiece of putting face 2.Under the state with expansion link 5 pull-ups, handle 4 might not be positioned at and carry the central authorities of putting face 2.This be because, even handle 4 not exclusively is in central authorities, also can push handle 4 and bag 100 ground that do not turn round is forwards moved.To fix carrying of expansion link 5 in the drawings and put 0 point of an end face of face 2 as benchmark, be 100 if establish the end face of opposition side, and the position of the handle 4 that then is pulled up for example is 15～80% position, is preferably 20～60%, more preferably 20～50% position.

(embodiment 3)

And then; Figure 19 is the side view of the bag that has castor 400 of relevant embodiment 3; If with expansion link 5 elongation and with handle 4 pull-ups, expansion link 5 is fixed on obliquely carry and puts on the face 2, to carry a side of putting on the face 2 eccentric towards central authorities so that handle 4 is from being fixed on.The bag 400 of Figure 19 carries the right side of putting face 2 owing to expansion link 5 is fixed on, thus if with expansion link 5 pull-ups, expansion link 5 is tilted, so that handle 4 is eccentric towards the left side from carrying the right side of putting face 2.The expansion link 5 that tilts is also same with the expansion link 5 of bending, under the state with handle 4 pull-ups, handle 4 is positioned at carries the central authorities of putting face 2.This be because, even handle 4 not exclusively is in central authorities, also can push handle 4 and bag 400 ground that do not turn round is forwards moved.

And then, though diagram not, bag also can the expansion link of bending be fixed on obliquely carry put a side of face, with the handle pull-up and eccentric towards central authorities from a side of carrying the face of putting.This bag makes crooked radius of curvature become big, and makes the inclination angle approach the right angle, can the handle pull-up be approached to carry the central authorities of putting face.This be because, tilt with crooked both in, can make the handle of pull-up eccentric to central authorities from the sidepiece that carries the face of putting.

The bag of above embodiment is fixed with two expansion links 5 at the two ends of carrying a side of putting face 2.Like this, expansion link 5 is configured in the structure that carries the side put face 2 owing to can bag main body 3 be configured in and carry on top roughly whole that puts face 2, carries the bottom surface of putting the bag main body 3 on the face 2 and become big strong point so have to make to be installed in.But bag of the present invention is not limited to expansion link is configured in the structure at the two ends of a side of carrying the face of putting.Also can expansion link 5 be configured in the side of for example carrying the face of putting, on the eccentric position of central authorities.

In other words expansion link 5 is pushing handle 4 under maximum states at contraction state, and handle 4 is positioned at the top or the top of bag main body 3, is stopped by block.Expansion link 5 is retracted, and makes the minimum position of handle 4, makes from the distance of bottom surface above handle 4 of castor 6 to be about 50cm.Wherein, be retracted and make handle 4 be in minimum position, make from the distance of bottom surface above handle 4 of castor 6 and be preferably 30～80cm, more preferably 35～70cm at expansion link 5.Expansion link 5 being shunk and handle 4 being under the minimum state, make bag main body 3 lower, thereby catch handle 4 easily than handle 4.Expansion link 5 is at elongation state, in other words under the state with handle 4 pull-up superlatively, is 60～100cm at the height from the bottom surface of castor 6 to the center of handle 4, is preferably the position of 65～85cm, stopped by block.

Expansion link 5 is shown in figure 15, possess along the vertical direction be fixed on with extending year put the guiding tube 5B on the face 2 and can be inserted in with coming in and going out among this guiding tube 5B two sections pull out bar 5A, be fixed with handle 4 in the upper end of pulling out bar 5Aa of epimere.In addition, two sections pull out among the bar 5A, make epimere pull out bar 5Aa than hypomere to pull out bar 5Ab thin, pulling out bar 5Aa and can insert with coming in and going out and lead to the pulling out among the bar 5Ab of hypomere epimere.And then, make expansion link 5 hypomere to pull out bar 5Ab thinner than guiding tube 5B so that the pulling out bar 5Ab and can be inserted among the guiding tube 5B with coming in and going out of hypomere.Guiding tube 5B with pull out bar 5A and can make thickness different metallic tube.Guiding tube with pull out bar and also can plastics or the shaped light metal side of being tubular be made.Expansion link among the figure has been made can be with two sections flexible structures, but expansion link also can be made 1 section telescopic construction, and also can make can be with structure flexible more than 3 sections.

In addition, the carrying of bag that has castor put platform 102 and is provided with on the plate 9 to following outstanding deep floor carrying to put.Deep floor is shaped integratedly to be provided with carrying and puts horizontal expansion and outstanding willfully strong floor 112A below the plate 9 downwards.And then this willfully strong floor 112A makes the zone of the below that is positioned at carrying cylinder 7 give prominence to and make and strengthen protuberance 108 downwards.This reinforcement protuberance 108 is strengthened the structure of basic framework 1 more firmly.The bag that has castor 500 that will possess reinforcement protuberance 108 is is below recorded and narrated its detailed explanation as embodiment 4.But, give identical label for the parts that have with embodiment 1 to 3 identical functions, and omit detailed explanation.In addition, for the characteristic of the parts that observably show relevant embodiment 4, the illustrated situation of omitting miscellaneous part is arranged.

Figure 23 is the part amplification stereogram of the bag that has castor 500 of relevant embodiment 4, and expression is from the stereogram of the basic framework 1 that wraps the observation of 500 rear side.In addition, Figure 24, Figure 25 are the stereograms of observing the bag 500 that has castor from bottom surface side, that is, and and the part enlarged drawing that carries the dorsal part of putting face 2 of expression Figure 23.Particularly, Figure 24 representes the stereogram from rear side of bottom surface 2A, and in addition, Figure 25 representes the stereogram from front side of bottom surface 2A.And in Figure 25, castor dots, and then, in Figure 24, omitted the diagram of castor.In addition, in this manual, the address of concerned direction defines as follows.Promptly; With link carrying cylinder 7 to carry the bight of putting plate 9 be benchmark; Respectively the short brink of putting plate 9 in OBL year is called the x direction of principal axis; Be called the y direction of principal axis with carrying the long side put plate 9, with carrying cylinder 7 axially, be called z direction of principal axis (the last direction among Figure 23) with the roughly consistent direction of normal direction of year putting plate 9.In addition, be called vertically, minor face is called horizontal stroke carrying the long limit put plate 9.

The bag that has castor 500 of embodiment 4 is same with embodiment 1, is made up of bag main body 3 and the basic framework 1 that can carry this bag main body 3.Basic framework 1 is shown in figure 23, has to carry removably to put carrying of bag main body 3 and put platform 102.Carry and to put platform 102 and have and put plate 9 in flat year, the posture of extending to top roughly with the two ends of the side of putting plate 9 from this year links has carrying cylinder 7.In addition, put the top of plate 9, can 3 contacts of bag main body put to carry on the face 2 in this year and put as carrying the face of putting 2 with carrying.Carry and to put plate 9 and also possess with carrying and put face 2 opposed bottom surface 2A and be in the side 2B that carries the periphery of putting plate 9.

The carrying of Figure 23 put platform 102 and carrying the peripheral part of putting plate 9, is being provided with deep floor at bottom surface side.Be located at the deep floor put this year on the plate 9 and be provided with highlightedly, and not to leaning on the top outstanding, so that it puts face 2 approximate vertical with carrying than carrying the face of putting 2 to carrying the below of putting plate 9.Thus, carry the deep floor put plate 9 and can not be projected into to carry and put on the face, can guarantee to wrap carrying of main body 3 significantly and put the zone.In addition, make global shape be put in rectangular year plate 9 around deep floor have with carry willfully strong floor 112A that the minor face of putting plate 9 is provided with abreast and with carry the vertical deep floor 122 that the long limit of putting plate 9 is provided with abreast.

Willfully strong floor 112A has the further outstanding reinforcement protuberance 108 (the grid shadow part of Figure 23) of the lower edge of making downwards.Reinforcement protuberance 108 is shaped integratedly and is arranged on the willfully strong floor 112A.In addition, strengthen protuberance 108 and be set to, be located at the below of carrying the linking part of putting plate 9 and carrying cylinder 7.The reinforcement protuberance 108 of Figure 23 is outstanding downwards, carries the linking part of putting plate 9 and carrying cylinder 7 to be located at, and is shaped integratedly with strong floor 112A willfully.More particularly, strengthening protuberance 108 is provided with the edge of year putting the composition surface 103 (the single-point line portion among Figure 23) that face 2 engages along carrying cylinder 7.In addition, strengthen protuberance 108 with the roughly posture configuration of quadrature of composition surface 103.This reinforcement protuberance 108 makes willfully the bending strength in the vertical plane of strong floor 112A improve, and improves and carry the bending strength of putting plate 9, will be fixed in top carrying cylinder 7 and firmly fix, so that it can not tilt in vertical plane is mobile.In the example of Figure 23, make the form on the part that is located at strong floor 112A willfully with strengthening protuberance 108, particularly, put on the linking part of face 2 with carrying only for being configured in carrying cylinder 7 surely.Thus, possessing the willfully strong floor 112A that strengthens protuberance 108 becomes the connecting area periphery structure more outstanding than other zones of putting plate 9 and carrying cylinder 7 carrying, can strengthen carrying the linking part of putting plate 9 and carrying cylinder 7 in the concentrated area.In addition, make its horizontal total length elongated, then can further improve and carry the intensity of putting platform 102, on the other hand,, then can realize carrying the lightweight of putting platform 102 integral body if the horizontal total length of strengthening protuberance 108 is shortened if strengthen protuberance 108.Strengthen protuberance 108 and can make willfully that the total length of the length direction of strong floor is 3cm～10cm, be preferably 5cm～8cm.If laterally the total length of the reinforcement protuberance 108 on (x direction of principal axis) is above-mentioned scopes, then can realize carrying the intensity and the light weight of putting platform 102 simultaneously.In addition, strengthen protuberance and also can not only be located on the willfully strong floor, can also be located on the vertical deep floor.Be located at reinforcement protuberance on the vertical deep floor and also be located at the below of carrying cylinder, put plate and strengthen linking carrying of carrying cylinder.

The outside of strengthening protuberance 108 with carry the side 2B that puts plate 9 and willfully the outside of strong floor 112A step is not set and makes roughly the same face.Make willfully strong floor 112A and strengthen protuberance 108 through 2B from the side to be identical face, having the willfully strong floor 112A that strengthens protuberance 108 can be to carrying that the length direction of putting plate 9 stretches out and can basic framework 1 being strengthened.In addition, also good aspect ornamental.And, can access carrying of the basic framework of embodiment 1 to 3 or other embodiments and put the additional at any time form of strengthening protuberance 108 in the plate 9, can as required basic framework 1 be strengthened.

Carry put platform 102 preferably will carry put plate 9, willfully strong floor 112A and the integral body of strengthening protuberance 108 are shaped with identical parts such as plastics integratedly.This be because, carry each parts put platform 102 and be shaped integratedly to carry as same parts and put platform 102 through constituting, can improve the intensity of basic framework 1, and can reduce whole component count and manufacturing simply.Strengthen protuberance 108 and be configured as and putting face 2 and approach the zone of rise part of carrying cylinder 7, make the willfully big shape of outstanding quantitative change downwards of strong floor 112A, be located on the linking part that carries the face of putting 2 and carrying cylinder 7 from carrying.And then the reinforcement protuberance 108 of Figure 23 is in carrying cylinder 7 and the periphery of carrying the composition surface 103 of putting face 2 and from the side in the vertical view of 2B, carry put abutment D that face 2 and the portion of holding up of carrying cylinder 7 engage with approximate right angle below, make the overhang maximum that becomes.This structure can strengthen carrying the linking part of putting plate 9 and carrying cylinder 7 most effectively through having the willfully strong floor 112A that strengthens protuberance 108.

In addition; Have the willfully strong floor 112A that strengthens protuberance 108 and also can make carrying and put that with easy effect the portion of holding up of the carrying cylinder 7 of stress to be arranged on the face 2 be the center, make the overhang H of strong floor 112A willfully bigger, in other zones, make the willfully less shape of overhang H of strong floor 112A.That is, shown in figure 24, preferably in the engaging zones 120 that carries face of putting 2 and carrying cylinder 7, the overhang m that strengthens protuberance 108 is maximum.For example in the example of Figure 23; In the vertical view of 2B from the side, having made will carry the face of putting 2 is that benchmark swells so that from the summit T roughly consistent shape of the vertical line S of this abutment D to bottom surface 2A side is drawn under with the curve of reinforcement protuberance 108 with the abutment D that the portion of holding up of carrying cylinder 7 engages with approximate right angle.That is, carrying cylinder 7 with carry the periphery put the composition surface 103 that face 2 engages, with carry the face of putting 2 and constitute the holding up in the portion of carrying cylinder 7 of approximate right angle, making willfully, the height up and down of strong floor 112A is maximum.In addition, the overhang of strengthening protuberance 108 is preferably compared and is carried the bight of putting platform 102, and it is bigger to be abutted against chalaza D side.Thus, can make the wall thickness of putting platform 102 that carries in the concentrated easily zone of stress become reinforcement greatly and effectively.But the summit T of protuberance might not be upward consistent with vertical line S, even there are some displacements also can access sufficient stiffening effect.

Willfully on the strong floor 112A reinforcement protuberance 108 being set, can make the structure of basic framework 1 become more firm through like this.The reasons are as follows.If the power that applies pushing force or make carrying cylinder 7 tilt to move to the below of carrying cylinder 7 direction then acts on bending stress carrying to put on the plate 9.Have the willfully strong floor 112A that strengthens protuberance 108 and improve bending strength, prevent the distortion and the damage of basic framework 1 from following reinforcement basic framework 1.Particularly, strengthen protuberance 108, the linking part 1 that stress is concentrated is easily strengthened effectively through near the portion of holding up of carrying cylinder 7, being provided with.Thereby this structure can also improve the resistance to impact to the very big impact of momentary action on carrying cylinder 7.

In addition, except possess that the willfully strong floor 112A that strengthens protuberance 108 brings from the reinforcement of bottom surface 2A side, also be provided with the reinforced wall 8 of record in the embodiment 1 to 3 simultaneously and strengthen base portion 34 (with reference to Fig. 8).Thus, can make to strengthen carrying three-dimensionally and put the structure of the engaging zones 120 between face 2 and the carrying cylinder 7, so can more effectively improve the intensity of the skeleton of basic framework 1 from 3 following, horizontal, vertical directions.

In addition, strengthen protuberance 108 preferably make make central portion higher and towards its both sides the shape of step-down gradually.This is because can improve based on the bending strength of strengthening protuberance 108, and improves resistance to impact.In addition,, make that to put face 2 big more to the overhang H of the lower end of strengthening protuberance 108 from carrying, can improve the intensity of basic framework 1 more effectively through strengthening protuberance 108.But,, then when the use of the bag that has castor 500, might strengthen that protuberance 108 contacts with castor 6 and the action smoothly that hinders castor 6 if make overhang H downwards excessive with the willfully strong floor 112A that strengthens protuberance 108.For fear of this undesirable condition, the height of protuberance 108 is strengthened in restriction, so that castor 6 can not contact.

Particularly, Figure 26 representes the part rearview of the bag that has castor 500 of relevant embodiment 4, and in addition, Figure 27 representes the part side view.Strengthen lower end such as Figure 26, shown in Figure 27 of protuberance 108, in the pivot region of yaw castor 6, be positioned at lean on than the upper end of wheel 114 above.More preferably, in the pivot region of castor 6, the overhang m of protuberance 108 is strengthened in restriction, between the top of the bottom surface 109 of strengthening protuberance 108 and wheel 114, gap d to be set.Thus, load is along the gravity direction effect etc. of bag, carry to put platform 102 and sinks downwards, and, even under the situation about narrowing down at the interval of the upper end of wheel 114 and the lower end of reinforcement protuberance 108, also can avoid strengthening contacting of protuberance 108 and castor 6.That is, always can keep the yaw motion of castor 6 smoothly.Gap d is just passable as long as the material of the fixed part through castor 6, rotating shaft, yoke and play are set at appropriate value, is about 2mm not carrying under the state of putting the bag main body and bag being supported oneself.But this gap d can be made as 1mm～4mm, is preferably 1mm～3mm.

In addition, strengthen protuberance 108 so long as the shape that is not in contact with on the castor 6 is just passable, not special qualification except arcuation, can also be the different shapes such as rectangular-shaped or semicircle shape, convex of rectangle or trapezoidal, parallelogram etc.And then, shown in the dotted line of Figure 27, can make also so that the degree that do not touch ground is outstanding that to increase the interarea of strengthening protuberance 108 long-pending downwards, and the shape of otch is made in the zone that contacts of the rotation of castor 6 that only will be through oscillating type.In embodiment 4; Shown in figure 27; On horizontal (the x direction of principal axis) of strengthening protuberance 108, in the lower zone of engaging zones 120, make the overhang m that strengthens protuberance 108 become big, make the overhang H that possesses the willfully integral body downwards of strong floor 112A of strengthening protuberance 108 become big.In addition, along with overhang m being diminished, make and strengthen protuberance 108 for circular-arc towards the two ends of strengthening protuberance 108.And, possessing the bight that carrying of carrying cylinder 7 put platform 102, the wheel 114 of making the overhang m downwards that reduces to strengthen protuberance 108, castor 6 can be across on the bottom surface 109 of strengthening protuberance 108 and the structure that rotates.That is, in the installation position of castor 6, possess the willfully strong floor 112A that strengthens protuberance 108 and do not contact, so bring obstacle can for the action of castor 6 with castor 6.Promptly; Make unique shape through strengthening protuberance 108; So that the overhang H of the willfully strong floor 112A in the engaging zones 120 is bigger than the overhang H that links the willfully strong floor 112A that the bight that carrying of castor 6 put platform 102 is arranged; Thus, can in the rotation freely of keeping castor 6, obtain to strengthen area fully.

In addition, willfully the number of configured of strong floor 112A also can be made as one, but preferably possesses a plurality of from the viewpoint of intensity.Like Figure 24, shown in Figure 25, also can be located at carry put plate 9 around willfully strong floor 112A additionally further willfully strong floor 112B is set carrying the inboard of putting plate 9.The willfully strong floor 112B of this inboard is parallel with willfully strong floor 112A on every side, and is configured near the central authorities of bottom surface 2A.In addition, the willfully strong floor 112B of inboard is same with willfully strong floor 112A on every side, preferably is positioned at the below of carrying the linking part of putting plate 9 and carrying cylinder 7.In the example in the drawings, with around willfully strong floor 112A be arranged on the bottom surface with inboard willfully strong floor 112B so that it is along carrying the edge of putting plate 9 and the linking part of carrying cylinder 7.And willfully strong floor 112A on every side is provided with inboard willfully strong floor 112B almost parallel ground, is installed in the castor 6 that carries the bight of putting face 2 so that it clips.Through be positioned at carrying cylinder 7 below bottom surface 2A on willfully strong floor 112A and inboard willfully strong floor 112B around being provided with, thereby can strengthen carrying the linking part of putting plate 9 and carrying cylinder 7 securely from bottom surface side.Particularly, can improve the bending strength of putting plate 9 of carrying effectively for the banking motion of the horizontal direction of carrying cylinder 7.In addition, willfully strong floor 112A on every side both can make its shape identical with inboard willfully strong floor 112B, perhaps also can be different.In the example in the drawings, willfully strong floor 112A on every side and inboard willfully strong floor 112B are identical shaped.If make the shape of deep floor 112A, 112B identical, then making is shaped becomes easily, and it is simple that manufacturing process becomes.Perhaps, also can the shape of a plurality of deep floor 112A, 112B be made different shapes, for example in the willfully strong floor in the zone that is configured in the rotation that does not hinder castor 6, make its outer deformation big etc. as far as possible, also can change size and shape in the configuration place.Perhaps, also can reduce the profile of deep floor and make the gross weight lightweight of bag.

In addition, inboard willfully strong floor 112B is made up of parts.Inboard willfully strong floor 112B is same with willfully strong floor 112A on every side, also can adopt to have with respect to formation and carry the shape that the parts of putting platform 102 have the reinforcement protuberance 108 of outstanding shape downwards.For example, also can make and be formed in the form on the deep floor 10 that has set integratedly strengthening protuberance 108.Among the willfully strong floor 112B of inboard in the drawings, for ease, outstanding zone (grid shadow part) is called reinforcement protuberance 108 will (to approach the direction on ground) downwards than the wall of deep floor 10.

In addition, carrying the bottom surface 2A side of putting plate 9, be provided with deep floor 10 each other across.Carry and put platform 102, on four jiaos of bottom surface 2A, have the deep floor 110 that is surrounded the bight in four directions by the deep floor 10 of quadrature and vertical deep floor 122 like Figure 24, shown in Figure 25.And carrying cylinder 7 is shown in figure 24, be located at the bottom surface 2A that is surrounded by the deep floor in bight 110 opposition side, carry and put carrying of plate 9 and put on the face 2.And then, shown in figure 25, castor 6 is fixed in the division portion that is divided by the deep floor 110 in bight.That is, castor 6 and carrying cylinder 7 are put plate 9 and are configured in up and down in the division portion of deep floor 110 in bight via carrying.In addition, the deep floor 110 that will possess the willfully strong floor 112A of two row of strengthening protuberance 108,112B and bight is provided with contiguously, can make the deep floor 110 in bight and the binding of bottom surface 2A become firm.As a result, can strengthen carrying cylinder 7 effectively from bottom surface side and put plate 9 with carrying.

And then, carry and to put platform 102 and on the linking part of carrying cylinder 7, be provided with the willfully strong floor of two row in parallel to each other, willfully strong floor 112A and inboard willfully strong floor 112B around promptly.Between the willfully strong floor 112A of these two row, 112B, carry and put below the plate 9, being shaped integratedly is provided with two row bottom surface deep floors 208, so that it is outstanding downwards.The carrying of Figure 24, Figure 25 put platform and to be provided with two row bottom surface deep floors 208, but this bottom surface deep floor 208 can be made 1 row, also can make in addition more than 3 row.And then, the carrying of the basic framework of Figure 24, Figure 25 put platform between the willfully strong floor 112A of two row, 112B, below carrying cylinder 7, be provided with and link floor 110A, link at this and link bottom surface deep floor 208 on floor 110A.Putting platform this year is shaped two row deep floor 112A, 112B, binding floor 110A and bottom surface deep floor 208 integratedly through plastics and is provided with.

Particularly, linking floor 110A is the part of the deep floor 110 in bight, is shaped integratedly with the edge and the bottom surface 2A that carry the linking part of putting plate 9 along carrying cylinder 7.The two ends that link floor 110A roughly link on quadrature ground with the willfully strong floor 112A of two row, 112B, that is, binding floor 110A is parallel to and year puts the length direction of plate 9 and dispose.Bottom surface deep floor 208 is attached at an end of bottom surface deep floor 208 and links on the floor 110A, is shaped integratedly with carrying to put plate 9 and link floor 110A.In addition, carrying among the figure put the be arranged at intervals with two row bottom surface deep floors 208 of platform 102 with equalization.And then, bottom surface deep floor 208 with willfully strong floor 112A, the parallel posture configuration of 112B.The length of bottom surface deep floor 208 is not special to be limited, and is about 4em.But the length of this bottom surface deep floor 208 then can obtain easness, intensity, the light-weighted balance of manufacturing if 3cm～5cm, is preferred.The bottom surface deep floor 208 of Figure 24, Figure 25 is attached at an end and links floor 110A and go up and be provided with, but the two ends that also can make the deep floor 208 in the bottom surface are provided with and link floor (not shown) and link structure above that.The configuration number of bottom surface deep floor 208 both can be one, also can be a plurality of, and a plurality of through being made as, can make carrying cylinder 7 securely and carry that to put platform 102 stable, and be preferred.Through setting up of bottom surface deep floor 208, can improve and carry the horizontal resistance to impact and the bending strength of putting face 2.Particularly, through being configured in the lower side of carrying cylinder 7, can relaxing at carrying cylinder 7 and carry and put the stress that is easy to generate in the join domain of plate 9, can support bigger load, be preferred.Make the willfully strong floor 112A of bottom surface deep floor 208 ratios, 112B among the figure low, make its width than willfully strong floor is wide, thereby improved intensity.But this bottom surface deep floor 208 can make its height and willfully the height of floor 112A, 112B is roughly the same by force.And then, make this bottom surface deep floor 208 higher, and can improve stiffening effect, and as not touching the height of castor 6, can avoid and the contacting of castor 6.Perhaps, also can be same with strong floor 112A willfully, 112B, it is higher and to the outstanding shape of foreign side to make the part that makes except the zone of the wheel of castor 6, and making up and down, width becomes big and the raising stiffening effect.

Through the willfully strong floor 112A of such setting, 112B and bottom surface deep floor 208, can be from multi-direction reinforcement engaging zones 120, the result can improve the intensity of basic framework effectively.Particularly, willfully strong floor 112A, 112B and bottom surface deep floor 208 be the structure with the configuration of multiple row almost parallel ground, in the bight of year putting platform 102 as carrying cylinder 7 and the engaging zones 120 of year putting face 2, can make its skeleton closeer and toughen up.In addition, leave the structure of setting, can strengthen basic framework and realize the lightweight that basic framework is whole through the multiple row of will be willfully strong floor 112A, 112B and bottom surface deep floor 208.The thickness of willfully strong floor 112A, 112B is 3mm.But this thickness can be made as 2mm～4mm.In addition, the thickness of bottom surface deep floor 208 is about 5mm.But the thickness of this bottom surface deep floor 208 can be made as 3mm～10mm.If willfully strong floor 112A, 112B and bottom surface deep floor 208 are thin excessively, then intensity might reduce, and in addition, if blocked up, then the gross weight of the cost of parts and basic framework might increase.

Bag 500 can make rectangular-shaped carrying put plate 9 and be of a size of multiple.For example Figure 28, Figure 29, Figure 30 represent that respectively carrying of various sizes put the upward view of putting platform 102 that carries of plate 200a, 200b, 200c.In addition, in these upward views, for around reinforcement protuberance 108 and the bottom surface deep floor 208 of willfully strong floor 112A and inboard willfully strong floor 112B apply the grid shade and conclusively show.In addition, in the example of Figure 28～Figure 30, face is put in carrying of 3 kinds of sizes of expression, and in these 3 kinds, the equal in length on the limit of length direction (y direction of principal axis) has only the laterally length difference on the limit of (x direction of principal axis).That is, in Figure 28, horizontal limit is shorter, in Figure 29, Figure 30, becomes big gradually.Particularly, the length on the limit of length direction * horizontal is 261mm * 150mm in Figure 28, is 261mm * 180mm in Figure 29, is 261mm * 210mm in Figure 30.But the shape of carrying the face of putting is not limited to above-mentioned size, can be made as than the dimension width of record wide or narrow width certainly and carry removably to put various bags.

In addition, like Figure 28～shown in Figure 30, carry the two ends of putting platform 102 minor face of 2A in the bottom surface, carrying the bight of putting plate 9, making deep floor is the deep floor 110 that square possesses the bight.The deep floor 110 in bight has at an end that carries the minor face put plate 9, along carrying the deep floor 111B in bight, the place ahead that the edge of putting plate 9 and the connecting area of carrying cylinder 7 makes the deep floor 111A in the bight, rear that deep floor 10 is provided with for the four directions and is located at the other end of minor face.The deep floor 111B in bight, the place ahead is set to square by horizontal willfully strong floor 112A, 112B and vertical longitudinally deep floor 122 and deep floor 10.The deep floor 111A in bight, rear can strengthen carrying the binding of putting plate 9 and carrying cylinder 7 from bottom surface side.And then willfully strong floor 112A on every side disposes with the almost parallel ground, outside that inboard willfully strong floor 112B clips the deep floor 111A in bight, rear.Through between the willfully strong floor 112A of two parallel row, 112B, setting the deep floor 111A in bight, rear, can the further reinforcement of the deep floor 11A in bight, rear further be strengthened carrying the connecting area of putting plate 9 and carrying cylinder 7 at bottom surface side.

And then Figure 31 carries the upward view of putting platform 102, the part enlarged drawing of expression bottom surface 2A.The fixed position of the castor 6 in the place ahead is the two ends on the long limit of bottom surface 2A, and castor is left each other to greatest extent.This is because wrap 500 thus and can not topple over and can stably support oneself.

The willfully side of the deep floor 111A in the bight, a distolateral covering rear of strong floor 112A on every side, the deep floor 111B in another bight, distolateral formation the place ahead.Thereby the deep floor 111A in bight, rear is positioned to the inside the position of thickness w that strong floor 112A is only staggered willfully in (right side of Figure 31).The allocation position that is positioned at the deep floor 111B in the deep floor 111A that carries the bight, rear on the angle put platform 102 and bight, the place ahead is gone up at length direction (y direction of principal axis) deviation is taken place.Inboard willfully strong floor 112B is corresponding to deep floor 111A setting obliquely with the deviation of the configuration of the deep floor 111B in bight, the place ahead in this bight, rear.Inboard willfully strong floor 112B is shown in figure 31; The one of which end cover the bight, rear deep floor 111A the side and contact; Along with tilting to the left towards the below of Figure 31, the other end constitutes 1 limit of the deep floor 111B in bight, the place ahead, and is attached on the vertical deep floor 122.In addition, in the example of Figure 31, the deep floor 10 of length direction is not set between the deep floor 111B in the deep floor 111A in bight and bight, the place ahead in the wings, makes and carry the gross weight put platform 102 and lighten.
