Description

Weighing device for weighing letters, packages and other objects.

The invention relates to a weighing device for weighing, for example, letters, packages, suitcases, persons, and so on. When sending letters and packages the problem regularly arises that the sender does not know what the correct franking amount is because the weight of the shipment is not known. In most countries a subdivision is used such as 100, 250, 500 grams, 1, 5, 10 kg and so on. Now there are various scales available for weighing letters, packages and other objects. However, these are often expensive and / or inaccurate. For example, there are electronic and mechanical scales, which often have the disadvantage that they are large in size and occupy a lot of space on a desk. Various letters and package weighers are known from patent literature, including patent DE 19827984Ά1.

It is an object of the invention to provide a solution to these problems. The object of the invention is to provide a practical, inexpensive and accurate means with which the correct weight category of letters, packages and other objects can be determined quickly and easily. To this end, the invention provides one or more flexible arches to be attached to each other, called weighing bows, which are wholly or partly made of a flexible material, such as for instance plastic or metal, which bend under the load of an object. The weighing arc consists for this purpose of a substantially horizontal flat part on which the object to be weighed can be placed, a so-called weighing platform (2), at least two legs (1) and at least two flexible straight parts, for example 30 leaf springs (3), which can be attached at a certain angle to the weighing platform (2a / b) and in line with the legs (la / b) by, for example, inserting them into recesses in the weighing platform (2c / d) and the legs (la / b) or snap it into the recesses by means of a click system. Various shapes for the weighing arc 1024458 I 2 I are possible, including for example a two-leg, tripod,

I four-legged and so on. Through the legs on a smooth and flat I

I place ground surface, for example a desk or I

I table, the object to be weighed can be placed on the weighing platform. I

Placed. When the weighing arc is loaded by a weight I

I will bend the flexible parts (3). The weighing platform (2) I

I and the two legs (1) can be rigid so that I

The bending of the weighing bows is caused solely by I

Bending the flexible parts (3). I

Due to the thickness and width of the flexible parts (3)

I, the flexibility can be varied and the I

calibrated in such a way that it is down I

protruding part of the weighing platform (4) the I

ground surface on which the weighing bow is placed touches at I

15 a certain weight. The user can use this weighting method I

I simply conclude whether the weight of a certain letter, I

package or other item is larger or smaller than the weight I

I indicated on the relevant weighing curve. If the I

weighing curve is not the weight of the shipment I

Smaller than the weight stated on the weighing bow. If the I

I bends the weighbow and touches the ground surface is the weight I

I of the shipment larger than the weight on the weighing bow I

I stated. In this way every I

I weight category calibrated by weight, for example I

100, 250, 500 grams, 1, 5, 10, 20 kg, 1, 2 lb and so on and I

in the case of weighing letters and packages the I

I correct weight category of the shipment and the corresponding I

I franking rate are determined. The different weighing bows I

I can easily be stacked on top of each other so that the I

I weights of the weighing arcs can be added. So I

I is created when stacking a weighing bow of 500 grams and I

I 250 grams a 750 gram weighing bow. The down I

The protruding part of the weighing platform (4) fits the I

I stack in a recess at the top of the I

I 35 weighing platform (4a) of the underlying weighing arc. I

I Because the parts are loose or partially assembled I

I are essentially flat, the weighing arc is very compact and I

I can be sent easily and cheaply by mail I

I the dimensions of which can be such that the weighing arc I

I 1024458 3 fits through the letterbox.

The flexibility of the flexible parts (3) of the weighing arc can be adjusted by varying the thickness and width of the parts (3), whereby the larger the thinner and narrower these parts, the more flexible the weighing arc becomes and the lower the required weight is to bend the weighing bow.

The ends of the two legs (1c / d) are rounded and smooth so that these legs (1) can slide over the ground surface with as little resistance as possible and in this way do not impede the weighing down of the weighing bow.

The weighing platform can be designed at the top with, for example, a rough or non-slip layer or with dots (5), thereby preventing the object to be weighed from sliding off the weighing platform.

The invention also relates to an alternative embodiment according to the same principle, but in which the straight flexible parts are replaced by curved flexible parts such as for instance curved leaf springs (6), which can be mounted horizontally in the weighing platform (7). If the weighing platform is loaded with an object, the bent flexible parts will bend and the weighing platform will bend to the ground surface, whereby the weight category of the object to be weighed can be determined in the above-mentioned manner.

The invention also relates to an alternative embodiment according to the same principle, but in which different weight categories can be determined with one weighing arc. The weighing arc is for this purpose provided with a hollow telescopically extending projecting portion (8). If the weighing arc is placed on the ground surface, these telescopic parts slide downwards by gravity or by manual pushing. If the weighing arc is loaded, the weighing platform (4) will be pushed downwards and at a certain weight the first part (8a) of the telescopic part (8) will touch the ground surface, which indicates a first weight category. If the weight is greater, the weighing platform (2) will drop and the second telescopic part (8b) will touch the ground surface with an associated 1024458

I 4 I

I weight category (8c), and so on. An alternative is that the I

I telescopic parts fixed manually in certain positions I

I can be through a click system. This way I

I the user set the weighing arc for for example 250 grams I

5 or 500 grams. I
