Definitions
- the object of this invention is a bag for luggage, documents, instruments or corresponding comprising a stiff body and several, mostly four legs on which the bag can be placed to stand.
- a spring scale equipment adapted between the handle of the bag and the body of it is known from e.g. the British Patent Specification 957,360 and the French Patent Specification 2,155,544.
- These spring scales give a reading of the bag weight when the bag is lifted by its handle.
- the scales are subjected to either a continuous load when the bag is carried or alternatively the weighing functions only when the handle alone is set in a weighing position.
- the handle has to be constructed in a manner differ ⁇ ing from the conventional and the fitting of the spring scale equipment into the handle is also difficult and expensive.
- Figure 1 is a perspective view of the ' bag according to the invention.
- Figure 2 shows partly a circuit diagram and partly schematically means for measuring and displaying the bag weight.
- Figure 1 shows a bag according to the invention, which bag comprises a stiff body 1 and four legs 2 (only two are seen in the Figure) on which the bag is placed to stand.
- each leg 2 and the body 1 of the bag strain-gauge transducers (not shown) are adapted so that the bag weight is transmitted through them to the supporting under ⁇ laying.
- These strain-gauge transducers are of the type the resistance value of which changes as a function of the pressure they are subjected to.
- a numeral display 3 which shows the bag weight.
- a contact button 10 is set by means of which the display 3 can when desired be switched on.
- Figure 2 shows more in detail the circuit measuring the bag weight.
- the actual measuring part consists of the measuring bridge, which comprises a series of strain- gauge transducers 6 (which are shown as one unit for the sake of clarity), the regulation resistance 7 and two balancing resistances 8 and a direct-current supply 9 connected over the bridge.
- the direct-current supply 9 can be e.g. a 5 V dry battery.
- the direct-current signal given by the measuring bridge is summed up and amplified with an operational amplifier 5. After this the signal is transformed into a digital signal with a A/D transformer 4, which also comprises a control unit for the display 3, which is preferably a liquid crystal display.
- the display 3 which can preferably be a 3

Abstract
Sac pour bagages, documents, instruments et autres, comportant un corps rigide (1) et plusieurs jambes (2), la plupart du temps (4), sur lesquelles le sac est placé pour tenir debout. L'inconvénient d'un tel sac conventionnel est qu'il est impossible de donner même approximativement son poids exact sans effectuer de pesée séparée. Afin de remédier à ce problème, un dispositif pour mesurer et afficher son poids brut ou net est ajouté au sac conformément à la présente invention. Le dispositif de mesure du poids comporte de préférence des transducteurs d'extensomètre qui sont adaptés entre chaque jambe (2) et le corps (1) du sac.
