The specific embodiment
In detail with reference to accompanying drawing, Fig. 1 shows the conventional wheeled luggage embodiment of known type now.Known suitcase with casters has the handle that separates and be parallel to the wheel shaft extension with wheel shaft.In order to catch the handle of chest, user's palm must as shown in the figure, require arm and wrist at the either direction half-twist towards front or rear, and this is to be realized by the combination that shoulder and forearm rotate.When dragging handle forward, shoulder stretches in about 10 ° to 40 ° scope along direction backward, therefore user's hand is placed the back of its health.The rotation that arm stretches backward with user's palm causes shoulder that about 10 ° to 30 ° stretching routine is arranged, and wrist departs from about 15 ° to 25 ° of ulna direction.In addition, user's arm keeps straight and the elbow joint full extension.Therefore, user's wrist drawing force as required also carries out bending, usually about 0 ° crooked to about 15 ° scope.Most of users can feel that the posture of transporting shown in Figure 1 is uncomfortable, and are all the more so when using for a long time and/or transporting heavy uneven weight.
In addition, conventional wheeled luggage has fixed handle length usually.Therefore, user's height can obviously influence the angle of inclination of luggage case casing to ground.The Ms on the right is in disadvantageous state among Fig. 1, because compare with the man on the left side among Fig. 1, its handle and ground form different angles, so she must apply the suitcase with casters that bigger power drags same size and weight.For conventional wheeled luggage shown in Figure 1, as shown in Figure 3, regulation x and y axle constitute paper, and the grip part of handle is parallel to the axis of the axle that two wheels are linked together, and make two axial lines all along the extension of z axle and perpendicular to paper.
Luggage case of the present invention shown in Fig. 2 is for just in user mode.As shown in Figure 2, the user can adopt more natural posture when the handle of grasping suitcase with casters.In case represent paper with x and y axle again, then the grip part of suitcase with casters of the present invention is in x, the y plane, and perpendicular to the axis that extends between wheel, rather than extends along the z axle.Therefore, the user does not need to stretch backward its arm and/or rotates its arm, make its palmar aspect forward or towards after.As shown in the figure, the user can drag suitcase with casters of the present invention now, and edge direction does not backward stretch its arm, and need not obviously rotate its wrist.
Figure 3 shows that the free casing schematic diagram of a conventional wheeled luggage, be used to form suitcase with casters of the present invention.For simplifying the analysis, make following hypothesis.At first, with respect to the quality of luggage case and content thereof, the wheel protonatomic mass can be ignored.The second, the radius of wheel is very little with respect to total physical dimension of luggage case.The 3rd, the mass motion of suitcase with casters is to pass ground owing to wheel rolls.The 4th, the rolling of wheel is a friction free.The required power of mobile luggage case is divided into the horizontal component F that represents drawing force
PVertical stress component F with the expression lifting force
L
The term of listing below using in Fig. 3 and in several equation, wherein asterisk (*) is used to represent the execution of a plurality of steps, wherein:
L is that core wheel is to the length of extending handle end;
θ is the angle of inclination about ground;
Ф is the angle between luggage case edge and the line OC, and wherein O is a core wheel, and C is the center of gravity on luggage case (in the plane);
W is a luggage case weight;
M is the luggage case quality;
A and b represent luggage case height and width respectively;
F
LIt is lifting force;
F
PIt is drawing force;
F
NIt is nominal force;
F
FBe frictional force (F
F=m*F
N);
μ is the coefficient of kinetic friction between wheel and the ground; And
Acc is that level is quickened vector.
Therefore will obtain following equation along the power addition of directions X:
∑F＝F
P-F
F＝m*acc，???????????????????(1)
Then become for pure rolling
F
P＝m*acc?????????????????????????????(2)
Power summation along the y direction is zero, therefore
F
L＝W-F
N?????????????????(3)
Suppose that center of gravity overlaps with the geometric center of chest, the moment sum that centers on core wheel is zero, and is represented by following equation:
-F
L*L*cos(θ)+F
P*L*sin(θ)+W*a/2*cos(θ)-W*b/2*sin(θ)
-m*acc*1/2(a
2+b
2)
1/2*cos(θ+φ)＝0????(4)
For stable system or system at the uniform velocity to move, acc=0 wherein, equation 4 becomes:
W*(a/2*cos(θ)-b/2*sin(θ))＝F1*L*cos(θ)????(5)
The tilt angle theta of chest is to extend the function of decreased food L and user's grasping height H, makes:
θ＝arcsin(H/L)?????????(6)
Hand approximately is 45% of an overall height H to the distance on ground because people's grasping highly is its arm when remaining on the side, therefore can adopt aforesaid equation to determine effective depth.Adopt the standard value of baggage compartment dimensions and weight, W=180 N for example, it is 0.8m/s for the zero-sum normal acceleration that a=58cm, b=23cm, L=100cm, Fig. 4 show acceleration
2The time lifting force as the variation of the function of box height, acceleration is the static and stable mobile status of null representation.Can know the advantage of seeing rolling luggage case terms of mechanics among Fig. 4.
Stable drag the required power of 180 newton's known configurations suitcase with casters and can change, approximately need 26 newton, approximately need 36 newton for short person people for tall people because of the height of people's height.For short person people's significant adverse, must apply about 50% lifting force than tall person's Ziren, when quickening even will apply bigger lifting force more.Although reduce the relative advantage of tall person's Ziren, with tall physiognomy ratio, short person people still must apply bigger lifting force.When horizontal drawing force being increased owing to acceleration, around the moment increase of wheel shaft, certainly will be to the landing ground pushing handle.Vertical-lift power produces moment in opposite direction, and purpose is to keep chest stable, therefore needs bigger lifting force.
Fig. 5 shows for the influence to required lifting force of people's handle length L of different heights.When handle is grown one meter, still be disadvantageous for short person people, he must apply bigger lifting force.When decreased food increased, the lifting force that short person people applies reduced.When decreased food further increased, force curve was near vertical.Therefore, long handle is useful for short person people.Certainly, only prolonging decreased food is not practical ways, because this is not easy to use and increased the gross weight of luggage case.
As the center of gravity of wheel luggage case be positioned at wheel shaft directly over the time, the required lifting force of balance chest is zero substantially.By shown in Figure 3, when θ+Φ=90, center of gravity be positioned at wheel shaft directly over.For the standard baggage compartment dimensions, wherein a=58cm and b=23cm, Φ then is approximately 22 °.Therefore, the optimum tilt angle θ of luggage case is about 68 ° in dragging.Adopt equation 6, set H and equal the about 45% of header tank height degree, best handle height then is approximately 0.485 times header tank height degree.Hand is sagging along the side fully when standing, and this moment, this value approximated the position of hand apart from ground greatly.
In order to obtain ergonomics handle grasping contact-making surface, can adjust shape, size, surface and the direction of handle according to these computings.Best, the surface coverage of grip part 32 (Fig. 6 A-7C) has anti-skidding compressible material, and does not have sharp edge.If desired, handle can have finger recess or other help user's grasping member parts.The cross section of handle is preferably rounded, oval or have the rectangle of fillet, can be fixed on well in user's the hand, prevented handle unnecessary rotation in hand, and made the user feel the direction of handle.Best, the length of grip part 32 is enough to make the highest user to hold with a firm grip with all finger and thumbs; Common four inches or longer grasping section length are enough to.When using handle to transport luggage case, Handle axis should be basically perpendicular to wheel shaft.The direction of handle should make luggage case be used, and does not make the wrist joint excessive deflection.The prehension end of handle can have flange or other parts so that arbitrarily reduce or significantly reduce slippage.In addition, the grip part of handle can constitute the sealing opening, makes finger can insert in the opening in operation.
The present invention has embodied two kinds of ergonomics design features that improve the suitcase with casters design.First characteristics are to control telescopic handle length, thus can be according to user's height and/or health ratio, and for example user's arm is arranged to suitable satisfactory length with respect to the ratio of its height with decreased food.On the contrary, when having adjusted the length of known suitcase with casters handle, the not obvious center of gravity that influences suitcase with casters.Specific user's best decreased food is generally when standing arm and hand, and sagging user makes things convenient for the length of grasping member along the side fully, and it can change according to the unique physical feature of any given individual.
Second design feature is the direction of handle.The ergonomics design handle that uses with suitcase with casters of the present invention can make the user drag luggage case with more comfortable and natural posture.All there is the ergonomics optimum position that makes human body sensory the most comfortable in each joint of human body.Therefore, making the user feel in the comfortable design, the present invention allows the user to take or at least roughly takes preferably or more natural posture.
Following form has been listed the body part and the joint of using when dragging suitcase with casters, and has provided the mutual comparison between conventional wheeled luggage and the present invention.
| Body part or joint | Optimum position | Common luggage case | Luggage case of the present invention |
| The shoulder abduction exercise | ????0° | ????10-30° | ????0° |
| Shoulder stretches | ????0° | ????10-40° | ????0-20° |
| Shoulder laterally rotates | ????0° | ± 45 ° of aggregate motions | ????0° |

As mentioned above, suitcase with casters of the present invention allows the user to adopt particularly more natural manner about its wrist joint, shoulder and forearm positions.Therefore, use suitcase with casters of the present invention to improve user's comfortableness, and be difficult for making the user to feel tired, and the danger of avoiding repeatedly the mobile model infringement.
Fig. 6 A-7C shows several embodiment of suitcase with casters of the present invention.Therefore, suitcase with casters of the present invention comprises the chest 10 with Handleset 12.Chest has a pair of parallel wheel 14 that separates, and their rotations are installed on the chest and have and run through the common longitudinal tensile strain axle that wherein extends.
Chest 10 is made of the back side 16,18 two opposite flanks 22, bottom surface, end face 24 and front 23, and all faces are connected with each other along its public side in a known way.Although shown is hard casing, can predict this casing can be replaced by semihard casing or soft casing or bag, so that transport and splendid attire user's personal belongings (not shown) therein.The cross spider 20 of the chest back side and bottom surface is parallel to the axis of two-wheeled 14.
Handleset 12 is installed in the groove 34 that forms in the casing when folding.When being easy to act as most Handleset 12 and being in its favorite places, handle basic with casing promptly top 24 and the back side 16 flush, as shown in Figure 6A.Handleset 12 is to constitute like this, locks when making the favorite places that it can be in being in tank recess.Although do not illustrate, for prevent loading and unloading during luggage Handleset open and/or be damaged, can with zip mode or Velcro type hook and the latch closure covering seals or sealed groove 34.Chest 10 also can be equipped with the common handle 26 that transports, it be installed in casing above.
When Handleset launches, can form the grip part 32 of elongation.It is basically perpendicular to the axis of casing wheel 14, and perpendicular to the cross spider 20 of box back surface 16 and bottom surface 18.The Handleset that constitutes allows to adjust total decreased food to adapt to the different users by this way.Best, make 32 expansion of grip part and make it be basically parallel to ground or other surface of being transported for suitcase with casters.Certainly, can use other structure of the Handleset 12 shown in Fig. 6 A-7C, as long as handle vertical wheel shaft when the operating position, the length of handle can be adjusted to user's height, and the center of gravity of not appreciable impact luggage case.
Handleset 12 is in its favorite places among Fig. 6 A.Locking or button release 28 are arranged on the Handleset to lock Handleset, as shown in the figure.The user is by moving to Handleset the operating position of opening as Fig. 6 B and 6C in conjunction with lock-button 28.In its operating position, be arranged in such a way grip part 32, even it is perpendicular to wheel shaft 14.

In case the Handleset appropriate location is also adjusted to the length that requires in its extended position (Fig. 6 C), locking device by using any known type and mechanism lock the interior pipe of Handleset about outer tube.For example, outer tube can have counterpart, and pipe was so that tightly clamp interior pipe in it compressed selectively.In addition, can be provided with a series of openings that separate in the interior pipe, the pin (not shown) inserts in this opening and locks together to manage 38 and 40 with two, thereby forms the handle with requirement length.In addition, pipe 38 extended positions in mark 42 is used to measure about outer tube 40, therefore the length of handle is extended in metering.
Determine to extend the length of handle according to above-mentioned ergonomics principle.In case determined a length for special user, then pipe 38 must outer tube 40 in, extend and reach manage in can being marked at metering mark on 38 or represent require length so that the later length that easily Handleset is set in requirement of permission user.
Can also be provided with and use bubble gauge 46 (Fig. 6 A), be used to help the user to adjust decreased food, so that correct user's ergonomic positions, make bubble be positioned at the center of horizontal plane, extend Handle axis and grip part and be parallel to the ground that suitcase with casters rolled across of transporting.Certainly, for specific people, with rule of thumb or by initial trial with there is the process of error to determine the decreased food that requires.But feature of the present invention is that it is θ about the inclination angle that ground forms that change or regulating handle length can significantly not change the handle bottom.
Although the load distribution in the casing can obviously not change the decreased food of requirement, but increase other luggage case, perhaps be placed on top 24, perhaps by top 24 suspentions and 23 extensions in the casing front, can change the center of gravity of casing, the result requires further to adjust decreased food.Owing to can adjust decreased food as required, as mentioned above, suitcase with casters of the present invention be very suitable for using under the situation of load changes in distribution or a user can use and/or spur under the situation of luggage case.
Fig. 7 A-C has shown the second embodiment of the present invention, and same numeral is represented two kinds of same parts in the luggage case.Handleset 12 also is contained in the back side 16 of casing, and comprises grip part 32, Handle axis 36, interior pipe 38 and outer tube 40.In its memory location (Fig. 7 A), Handle axis 36 and interior pipe 38 are in line and arrange and be contained in the outer tube 40 of Handleset, and the flared ends 33 of grip part is installed in the tank recess 34.
Lock-button 28 also be used for Handleset be locked in the casing its memory location or by this memory location release lever assembly.For Handleset being moved to its operating position, by pressure-locking button 28 and upwards pulling out grip part 32 and release lever grasping member 32, till obtaining to require total elongation.Shown in Fig. 7 C, grip part 32 then around pivot 50 and centrepin 51 along arrow 44 ' shown in the direction rotation, make the grip part be basically parallel to ground (in use) and perpendicular to the axle of wheel 14, shown in Fig. 7 B.
In pipe 38 can have actual height indicator 52 (Fig. 7 B) or any indicator 52 ' (Fig. 7 B), be used to represent or measure in the pipe 38 requirement distances that must outer tube 40 in, extend so that the decreased food of acquisition requirement.In Fig. 7 C, extend or adjusted interior pipe 38 the people of 5 ' 5 " to 5 ' 7 " at the height scope.
Suitcase with casters embodiment can also have " bubble " indicator, and as mentioned above, it is used to adjust suitable decreased food.Adjust decreased food, make when the grip part of handle remains parallel to ground substantially, the center of gravity of luggage case will be on wheel or almost on wheel, is represented by the centering bubble in the bubble gauge.This makes decreased food adjusted, make when drag or promote luggage case, acquisition optimum tilt angle, wherein center of gravity be positioned at wheel directly over or almost be positioned at wheel directly over.In case to be fit to specific user's best decreased food, then the user then can utilize the predetermined decreased food that requirement adjusted to decreased food easily by mark on the handle or other indicator.
