A device for size check of luggage, said device comprising means for delimiting a three-dimensional space corresponding to maximum allowed size of the luggage.
Description
A DEVICE FOR SIZE CHECK OF LUGGAGE
FIELD OF THE INVENTION AND PRIOR ART
The present invention is related to a device for site check of luggage.
The device may be applied at all places where the size of the luggage is an important pararneter_ The device is therefore especially applicable where the storage space of an object, for example a vehicle, a boat or an aircraft, is limited. The device is especially applicable for size check of hand luggage intended to be brought into an aircraft_ The airline companies have regulations regarding the maximum allowed size and/or weight of hand luggage. The size limitation is in some cases defined in that the hand luggage has to fit under a seat for the traveller in question, or in a space for hand luggage, said space being situated above the position of the seat.
Such an indefinite limitation might lead to discussions regarding the exact allowable size of the hand luggage that may be brought into the aircraft by the traveller. It could be unpleasant for the control crew to refuse a traveller with a suspiciously large hand luggage to pass.
A hand luggage spacing located above the seats is often intend-ed for housing hand luggage for several travellers. This results in the traveller getting to the spacing first might fill up the com-plate spacing with his own hand luggage, which results in that the other travellers, who also were to place their hand luggage WO 99!170 75 PGT/SE98/01730 into said spacing, will have to place their hand luggage in other _ places, for example under the seat. It might get crowded in the '.
aircraft if also these travellers should bring a larger hand luggage than allow~d, which results in difficulties both for the ' cabin crew and for the travellers to move around.
Housing luggage in the cabin without fastening it properly is a safety risk. Non-fastened luggage might be displaced in the cabin when the aircraft banks yr is brought to make sudden changes in the height direction, for example due to air pockets.
This safety risk increases with an increasing amount of luggage.
SUMMARY OF THE INVENTION
The object of the invention is to provide a device for size check of luggage, which eliminates the above mentioned dlsadvant-ages.
This object is achieved by the invention in that the device comprises a passage, which the luggage is to pass through, the passage being delimited by delimiting means in order to put an upper limit on the size of the luggage regarding the height and width thereof, the delimiting means comprising a first delimiting portion forming a base portion for delimiting the passage down-wards, a second delimiting portion forming an upper portion for delimiting the passage upwards, and third delimiting portions forming side wall portions for delimiting the passage sideways.
The inventive passage involves an easy and safe method to de-termine whether a specific piece of luggage has a size below the upper size limit or not_ The piece of luggage is approved regard- , ing the height and width thereof if it can be brought through the passage. It is however not approved if it cannot be brought to pass through the passage and should then be treated in some other way. tn the case of hand luggage, a non-approved piece of luggage will thus not be possible to be brought into the aircraft WO 99117075 3 pGTlSE98/01730 as hand luggage. but may instead be labelled for storage in the ordinary aircraft storage space.
The inventive device has means for delimiting the allowed luggage length to a set value in order to achieve a maximum three~dimensional luggage size. According to a preferred em-bodiment, a sensor arrangement utilising a non-contact sensing method may be used for delimiting the size of the luggage in the longitudinal direction. According to a preferred embodiment, the sensor arrangement ut;llses a suitable radiation, for example electromagnetic radiation, such as light. It is, how~ver, also within the scope the inventive Claims that the sensing operation regarding whether the actual length of the luggage exceeds a maximum allowed length value or not, is performed with the aid of other types of sensor arrangements, for example arrange-ments based on mechanics. It is, for example, possible to ar-range fingers in a suitable distribution along the luggage and movable towards the same in such a way that information re-garding approval or non-approval of the luggage length may be 2Q achieved by registering whether the fingers contact the luggage or not. Other types of sensor arrangements may also be of in-terest, such as pneumatical arrangements. The above mention-ed radiation could be formed by one or a plurality of air jets located in such a way that information regarding the length of the luggage is obtained by registering whether said jet or jets hit the piece of luggage or not.
Generally, it is established that the inventive device makes it possible to easily and effectively control whether the luggage has the allowed size yr not. This Implies that personnel respons-ible for the luggage check do not need to carry out any sub-jective estimations of the luggage size. The inventive device may instead be used for providing an objective estimation. This is of particular interest at the size check of hand luggage for airlines. .
WO 99/170?5 4 . PCT/SE98J01730 BRIEF DESCRIPTION OF THE DRAWING
With reference to the appended drawing, a more specific dis closure of embodiment examples of the invention wilt follow hereinafter:
Flg. ~ illustrates a perspective view of a first preferred embodi-ment of the inventive device.
Fig. 2 illustrates a side view of the first preferred embodiment of the invention, with a piece of luggage indicated by dotted lines in the device.
Fig. 3 illustrates a partly cut front view according to fig. 2, rotated 90° in relation to the view in fig. 2 DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
OF THE INVENTION
Fig. 1 illustrates a perspective view of a first preferred embodi-ment of the inventive device. The device has means for delimit-ing a three-dimensional space, which corresponds to the maxi-mum allowed size of th~ luggage. The delimiting means delimits the space in three mutually perpendicular directions. In the ver-tical direction, the space is delimited downwards by a base por-tion 1 and upwards by an upper portion 2. The space is delimit-ed sideways by two wall portions 3, 4 arranged on opposit~
sides of the base portion 1. The wall portions 3, 4 are arranged in parallel with each other, the base portion 1 and the upper por-tion 2 also being arranged in parallel with each other, and the wall portions 3, 4 being arranged in a substantially perpen, dicular angle in relation to the base portion 1 and the upper por-tion 2 in order to obtain a parallelepipedical space. A passage S, according to fig. 1, formed running through the device for bringing luggage to and from the space delimited by the de-limiting means.
WO 99/I7075 5 PC'I/SE98I01730 The delimitation of the space in the longitudinal direction thereof is achieved by means of a sensor arrangement comprising two sensor elements 5, 6 spaced in th~ longitudinal direction of the space, and a central processing unit arranged in contact with the sensor elements 5, 6. The device also comprises a signal ar-rangement 7 arranged in contact with the sensor arrangement, The signal arrangement is arranged in such a way that it sends a signal when the extension of the luggage is longer than the maximum allowed length in a direction controlled by the sensor arrangement.
The size of the luggage may thereby be controlled in three substantially perpendicular directions. The luggage is intended to be brought into the passage and to the space through a first opening 8 of the device. The luggage should further be brought through the space and out through a second opening 9 of the device. The sensor arrangement according to the first preferred embodiment of the invention operates in such a way that the respective sensor element 5, 6 forms an optic delimination line for delimiting the three-dimensional space in the longitudinal direction thereof. The sensor elements 5, 6 are arranged in the wall portion 4 and operate both as senders and receivers of a light beam, reflected at the opposite wall portion 3. A signal is sent to the central processing unit when the light beam is re-fracted by an object, for example a piece of luggage. The control of the extension of the luggage in the longitudinal direction of the space takes place in that the luggage brought through the opening 8 and towards the opening 9 will refract the light beam radiated by the sensor element 6 when a first portion of the luggage is brought out of the space. The sensor ~lement 6 sends a signal to the central processing unit which controls whether the light beam radiated from the sensor element 5 is non-refracted. If it is non-refracted, the length of the luggage is within the maximum allowed value in the longitudinal direction of WO 991170?5 6 PCT/SE98J01730 the control space, and the luggage is approved for further trans-port as hand luggage. 1f, however, both light beams radiated from the sensor elements 5, 6 are refracted at the same time, the luggage length is longer than allowed. The central process- -ing unit wilt then react and contact the signal arrangement.
Thus, the distance between the sensor elements 5, 6 corre-sponds to the maximum allowed length of the luggage in the longitudinal direction of the space.
According to the first preferred embodiment of the inventive device, the control of the extension of the luggage in the height direction and the lateral direction of the space is effected by the base portion 1 and the upper portion 2, and by the two wall por-tions 3, 4. If the luggage, for example has a larger extension in 't5 the lateral direction of the space, than tha distance between the side walls 3, 4, the luggage will not be possible to be moved through the opening 8 of the device. Suitably, personnel are present at the size check of the luggage in order to control that travellers cannot pass the size check with hand luggage of a larger size than allowed without the luggage being sire checked with aid of the device.
Fig. 2 illustrates a side view of the inventive device according to the first preferred embodiment. A piece of luggage 10 is in-dicated by dotted lines inside the device. The piece of luggage has an extension in the height direction and the lateral direction, substantially corresponding to the maximum allow~d extensions in these directions. The upper portion 2 has an opening 11 ex-tending in the direction of the passage. The luggage 10 is in-tended to be brought through the passage by a force applied on a handle 12, or a strap, extending through the opening 11. The piece of luggage 10 may also be supported by th~ base portion 1 during the movement through the passage. Normally, the tra-veller moves the piece of luggage through the passage by carry-ing it at a distance from the base portion.
WO 99117075 7 PCr/SE93I0I730 Fig. 3 illustrates a partly cut front view of the inventive device according to the first preferred embodiment. Fig. 3 illustrates the sensor elements 5, 6 spaced in the longitudinal direction of the space. The piece of luggage 10 is indicated by dotted lines in fig. 3 and has an extension in said longitudinal direction exceed-ing the distance between the sensor elements 5, 6 and the length of the piece of luggage, therefore, exceeds the maximum allowed length.
The three-dimensional space corresponding to the maximum allowed luggage size has a substantially parallelepipedic shape according to a first preferred embodiment. The shape of the space may however, within the frame of the inventive claims, differ from a parallelepipedic shape. The device rnay. for ex-ampt~, be formed in such a way that the shape of the three-dimensional space corresponds to a spacing for hand luggage, said spacing normally being located above the seats arranged in the cabin of an aircraft.
According to a second preferred embodiment of tlne sensor arrangement, two pairs of sensor elements arranged a~t each end of the space in the longitudinal direction thereof being in contact with each other. A first sensor element in each of the sensor element pairs is arranged in one of the wall portions, and a second sensor element in each of the pairs of sensor elements is arranged in the other wall portion. One of the sensor elements operates as a sender and the other sensor element operates as a receiver. The sensor element operating as a sender may thereby be a light source, and the sensor element operating as a receiver may be light sensitive and arranged to react when it is supplied with light or when a supply of light is interrupted.
The sensor arrangement may within the frame of the inventive claims be formed in a plurality of different ways. According to a third preferred embodiment of the invention, a plurality of sensor elements are arranged, preferably in a line, in the direction of WO 99JI7075 $ PCTJ8E98J01~30 the passage, on both side walls 3, 4, the sensor elements forming a plurality of sensor element pairs. The two lines of sensor elements are arranged substantially opposite each other.
The length of these two lines of sensor elements is preferably larger than the maximum allowed length of the piece of luggage in the longitudinal direction thereof. It is, thereby, easy to measure the length of the piece of luggage in the longitudinal di-rection of the space by placing it between the two lines of sensor elements. The central processing unit registers the num~
bar of interrupted light beams between the sensor element lines.
The accuracy of the measurement increases with the number of sensor elements. The sensor elements in one of the lines of sensor elements operate as senders and the sensor elements in the other line of sensor elements operate as receivers. It is, by arranging the central processing unit in connection with the signal arrangement, possible to generate a signal when the length of the piece of luggage in the longitudinal direction of the space exceeds the maximum allowed length in this direction.
The sensor elements are preferably formed by photoelectric cells.
Each of the delimiting means described above in the form of a base portion. an upper portion and wall portions form a delimit-ing plane for the space. These delimiting means are continuous, but it is also within the frame of the inventive claims to arrange such delimiting means intermittent, such as a delimiting means in the form of a grid structure.
According to a second preferred embodiment of the inventive device, it has a wall portion delimiting the space in the longitu-dinal direction. Such a wall portion is preferably arranged so that it may be arranged in two different conditions, namely an active condition preventing luggage from being brought out from the space through the opening 9, and en inactive condition allowing luggage to be brought out through the opening 9. Such WO 99/17075 g . PCT/SgggI01?30 a wall portion may, for example, be fellably, or pivotably ar-ranged between these two conditions. The pivota~biiity may, for example, be achieved by a hinge joint. It is thereby possible to control the length of the piece of luggage in the longitudinal direction of the space by means of such a further wall portion in accordance with the following text:
The further wall portion is arranged in the active condition and a piece of Luggage is brought into the space to a position contact-ing said wall portion. The sensor arrangement senses thereafter whether the length of the piece of luggage is larger than allowed by means of a sensor element arranged in a position opposite said wall portion in the longitudinal direction of the space. Said wall portion is brought into the inactive condition if the piece of luggage does not refract the light beam of the sensor element located at a distance corresponding to the maximum allowed length of the piece of luggage from said wall portion in the longitudinal direction of the space, and the piece of luggage is moved through the opening 9 and out of the space. Such a 2o further wall portion is preferably connected to the central pro-cessing unit so that the central processing unit controls the dis-placement of the wall portion between the active condition and the inactive condition, According to a third preferred embodiment of the inventive devi-ce, it comprises an arrangement for moving luggage. The mov-ing arrangement preferably comprises a conveyor delimiting the space downwards. The length of such a conveyor in the direc-tion of the passage is preferably longer than the length of the 3D space in this direction. A piece of luggage for size check is lo-cated onto the conveyor and the piece of luggage is moved through the opening 8 and into the space when the conveyor moves. An upper portion forming the delimiting means in an up-wards direction of the space may be formed in one piece if such a conveyer is present. The opening 11 through the upper portion WO 99117075 PCT/~E98/01730 2, according to the first preferred embodiment of the invention, is therefore not necessary.
It is, of course, within the frame of the inventive claims to delimit the space in other directions than the longitudinal direction by means of the sensor arrangement. The device may for example be arranged with sensor elements delimiting the extension of the space upwards. The sensor element will react if a piece of luggage is located on, or moved along the base portion 1, if the piece of luggage extends longer than the maximum allowed ex tension in the height direction, i.e. the distance between the base portion and the sensor element/-s. It is also within the frame of the inventive claims to replace one of the wall portions or both of them with sensor elements forming an optical delimi tation of the space.
According to a further preferred embodiment of the inventive device, it also comprises an arrangement for measuring the weight of the luggage. Such a measuring arrangement is pre-ferably arranged in the base portion of the device. The measur-ing arrangement may however also be arranged in an upper part of the device. A piece of luggage may thereby be controlled regarding both the size and weight thereof_ The device has preferably a converging portion at the opening 8 in order to facilitate insertion of a piece of luggage into the device.
It should be noted that the embodiments discussed above and illustrated in the drawing only are to be regarded as examples_ The invention may thus be realised in different ways within the inventive concept. It is especially noted that men skilled in the art after having been presented to the inventive solution, of course, are capable of making modifications of the exemplifying embodiments without leaving the frame of the inventive claims.

It is thereby possible to control the length of the piece of luggage in the longitudinal direction of the space by means of such a further wall portion in accordance with the following text:
The further wall portion is arranged in the active condition and a piece of Luggage is brought into the space to a position contact-ing said wall portion. The sensor arrangement senses thereafter whether the length of the piece of luggage is larger than allowed by means of a sensor element arranged in a position opposite said wall portion in the longitudinal direction of the space. Said wall portion is brought into the inactive condition if the piece of luggage does not refract the light beam of the sensor element located at a distance corresponding to the maximum allowed length of the piece of luggage from said wall portion in the longitudinal direction of the space, and the piece of luggage is moved through the opening 9 and out of the space. Such a 2o further wall portion is preferably connected to the central pro-cessing unit so that the central processing unit controls the dis-placement of the wall portion between the active condition and the inactive condition, According to a third preferred embodiment of the inventive devi-ce, it comprises an arrangement for moving luggage. The mov-ing arrangement preferably comprises a conveyor delimiting the space downwards. The length of such a conveyor in the direc-tion of the passage is preferably longer than the length of the 3D space in this direction. A piece of luggage for size check is lo-cated onto the conveyor and the piece of luggage is moved through the opening 8 and into the space when the conveyor moves. An upper portion forming the delimiting means in an up-wards direction of the space may be formed in one piece if such a conveyer is present. The opening 11 through the upper portion WO 99117075 PCT/~E98/01730 2, according to the first preferred embodiment of the invention, is therefore not necessary.
It is, of course, within the frame of the inventive claims to delimit the space in other directions than the longitudinal direction by means of the sensor arrangement. The device may for example be arranged with sensor elements delimiting the extension of the space upwards. The sensor element will react if a piece of luggage is located on, or moved along the base portion 1, if the piece of luggage extends longer than the maximum allowed ex tension in the height direction, i.e. the distance between the base portion and the sensor element/-s. It is also within the frame of the inventive claims to replace one of the wall portions or both of them with sensor elements forming an optical delimi tation of the space.
According to a further preferred embodiment of the inventive device, it also comprises an arrangement for measuring the weight of the luggage. Such a measuring arrangement is pre-ferably arranged in the base portion of the device. The measur-ing arrangement may however also be arranged in an upper part of the device. A piece of luggage may thereby be controlled regarding both the size and weight thereof_ The device has preferably a converging portion at the opening 8 in order to facilitate insertion of a piece of luggage into the device.
It should be noted that the embodiments discussed above and illustrated in the drawing only are to be regarded as examples_ The invention may thus be realised in different ways within the inventive concept. It is especially noted that men skilled in the art after having been presented to the inventive solution, of course, are capable of making modifications of the exemplifying embodiments without leaving the frame of the inventive claims.
