Description
Technical field
The present invention relates to a kind of luggage case, especially a kind of side-pull type luggage case (referred to as drawing case) belongs to luggage case
Field.
Background technology
According to reports, China is maximum luggage producing country and country of consumption in the world, account for about luggage whole world yield three/
One, China's luggage industry keeps rapid growth, and the above luggage marketing industries gross output value of scale in 2015 is up to 167,400,000,000, it is contemplated that
The year two thousand twenty, scale above luggage marketing industries gross output value in China's is up to 283,600,000,000.Conservative estimation, luggage case account for luggage proportion three/
One, it is 94,500,000,000.10% share, prediction the year two thousand twenty output value nearly 10,000,000,000, it is seen that market prospects are considerable are accounted for by the luggage of the present invention.
Existing luggage case has generally included case body, telescopic lever and universal wheel, is widely used because its is easy to use.Suitcase has
Very long history, from only for the leather trunk of accommodating laundry, various Portable suitcases, trolley case by now, people's hand
In luggage case in continuous evolution.It, can be voluntarily by remote control for example, having at present it has been reported that some high-tech luggage cases
It moves and immediately luggage case behind；Also having can be by assembling, when the luggage case that battery truck is ridden.These high-tech rows
Lee's case is although easily, price is expensive, it is difficult to popularity.Therefore the most commonly used or traditional rod-pulling type of current people
Luggage case.And existing pulling-rod trunk, although it has had a very long usage history, people seem to be accustomed to, are general
All over receiving them.But the present inventor is already found that, the place that it has some quite unreasonable.During being first implementation
Stress is unreasonable.As shown in Fig. 1 (a), during implementation, thrust is in pull rod, since pull rod is located at babinet side, rather than
Plane where center of gravity, therefore torque is generated in the horizontal plane, so that babinet is rotated, generates moment of flexure in vertical plane, babinet is made to be easy to incline
It covers.Either when carrying out, trolley case must be acted on by a reversed torque on hand, balance could be kept.With
For 20 inches of luggage cases, it is assumed that load-carrying 23kg, universal wheel are 0.018-0.02 with ground surface friction coefficient, are maximized
0.02, then need the reactive torque balance for applying about 650Nmm.That is it needs to spend more prodigious strength, it could well forward
Carry out.It if it is by the oblique placement of babinet, is drawn and is gone by pull rod, then need to bear the downward gravity work of article in babinet on hand
With shown in Fig. 1 (b), still by taking 20 inches of luggage cases as an example, load-carrying 23kg, universal wheel takes 0.02 with ground surface friction coefficient, leads to
Two big equilibrium condition of system, i.e. power and equalising torque are crossed, following result is obtained by calculation：When luggage case and ground angle are
At 45 °, hand stress 80N, when luggage case and ground angle are 60 °, hand stress 140N, therefore under general drawing row state, human hand
It is subjected to the power of 80-140N, about 8-14kg object gravity, and as load-carrying increases, human hand stress increases, therefore pedestrian can feel to eat
Power.
Meanwhile pull rod is built in box house, due to the presence of pull rod, can be flat part originally, and just have pull rod
Protrusion, as shown in Fig. 1 (c).This part protrudes, and just influences very much the article for placing flat class, causes the waste in many spaces.
Since it cannot entirely place article, the diameter of the pull rod corresponding space in drawbar height direction in figure in other words, such as Fig. 1
(c) it shown in, since slightly larger article needs slant setting etc., is difficult to be utilized.According to the THICKNESS CALCULATION of babinet, if
It by taking 20 inches of luggage cases as an example, theoretically analyzes, cabinet space shared by pull rod top surface to chest bottom surface 2.5cm ranges is about
12.5%.Even if taking pull rod center line (dotted line in figure), with away from bottom plate 1.5cm calculate, shared by ratio also up to 7.5%.I.e.
Make to be again larger 28 inches of luggage cases, both of the aforesaid data are respectively 8.3% and 5%.As it can be seen that usually there is 5-10% or so
Space be unable to get and efficiently use.Other than the two disadvantages, 1) presence of pull rod is preparing the babinet for having pull rod side
When, preparation process is more complicated than no pull rod side.Increase manufacturing cost.2) pull rod is located at the side of babinet, is carried by pull rod
When drawing chest, it is also be easy to cause the fracture of pull rod, and luggage case is caused to be in half useless state.
In order to solve the problems of aforementioned trolley case, the present invention proposes a kind of to have discarded pull rod, having only used drawing completely
The side-pull type luggage case (referred to as drawing case) of band.Case is drawn to overcome completely in aforementioned background art existing for existing luggage case
Many advantages, such as utilization ratio of all problems, babinet preparation simplicity convenient with carrying out stablizing, and cabinet space is high.Therefore,
It is expected that after launching, it is believed that consumer's approval can be obtained in time, win customer's welcome.Product passes through the several years post sales,
It is entirely possible to the market share more than half.Even if accounting for domestic market share 10% by prediction in aforementioned background art, produce
Value also to generate huge economic benefit, and will generate preferable social benefit close to 10,000,000,000.
