DESCRIPTION

The invention relates to a weighing device for weighing objects that are suspended from the weighing device.

To our knowledge, there is currently no pocket scale that is suitable for universal use, since due to the handle and hook size, as well as the technical structure, only a very specific area of application is possible (e.g. spring scales for anglers). Our invention is based on the task of achieving universal use of the scale with minimal dimensions.

In our opinion, the solution to this problem is to maximize the handle and hook size, whereby an "S-hook-shaped" arrangement of both parts is possible for extreme application situations.

The weight measurement is carried out electronically according to the DMS principle.

The desired compactness is achieved by an essentially circular shape of the scales. The maximum handle size was achieved by dividing the full circle into two semicircles, with the scale body and the handle each forming one. The maximum hook size was achieved by integrating the hook into the entire scale and describing a three-quarter circle.

The ^"MS -hook" arrangement is achieved by pivoting the handle and the swiveling of the hook, so that bending moments on the elastically deformable part are avoided, since this is always perpendicular to the load.

To determine the weight of the load to be weighed, the hook is first fully extended. The scale is then put into operation using the multi-function switch and the weighing range is set at the same time. There are 2 weighing ranges with different maximum loads and divisions available. 殮 vii^d the l&s* sus hook iDe"?e5*ie"fe; the scale is lifted up by the handle and held steady.

The handle remains locked by the multifunction switch so that the outer shape still forms a full circle.

If the load is too heavy to be held freely, the scale can be hung on a suitable object by the handle, whereby the handle can be swung out further if necessary. To do this, the multifunction switch is pushed back so that an "S-hook-shaped" arrangement of handle and hook is achieved.

Furthermore, the free pivoting of the joint prevents the build-up of bending moments on the elastically deformable part.

The invention and preferred embodiment of the invention are explained in more detail below using an exemplary embodiment with reference to the following drawings:

Fig. 4-6 comprise 3 assemblies, namely the handle Fig. 4, the body Fig. 5, and the display means/multifunction switch Fig*6.

The handle (3) from Fig.4 consists of an essentially semicircular steel core coated with thermoplastic, at one end of which there is an open angle piece (6).

When the handle (3) is folded out, the angle piece (6) forms a hook and when closed, it is used to lock the handle (3) to the body (A)* At the other end of the handle (3) there is a threaded hole and a screw, by means of which the handle (3) is pivotally attached to the body (4) Fig.5. The outer mechanically load-bearing part of the body (4) Fig.5 consists of an angled sheet that forms the outer shape. The body interiors (10) accommodate the electronic components and connections in the form of cast-in blocks. The body (4) also has a through hole through which the bolt (7) is inserted. The bolt (7) fixes the elastically deformable carrier (5) to the body (4) so that it can rotate. The cross-section (12) of the body (4) has a gap that is suitable for loosely accommodating the hook (1) and elastically deformable carrier (5). Furthermore, the bolt (7) is also designed to guide (25) the indicating means (2). The notch (11) on the body (4) accommodates the open angle piece (6) when the handle (3) is locked on the body (4).

Fig.6 describes the display device (2), which functions as an ON/OFF switch and selector switch for two measuring ranges. It also serves to lock the pivoting handle (3) to the body (4) by fixing the open angle piece (6) laterally.

The display device (2) Fig.6 consists of an angled U-shaped sheet metal housing and accommodates an LCD display (15)» a 9 volt block (1(?) as well as cast-in electronic components (17).

The guidance (25) of the indicator (2) on the body (4) is achieved on both sides by the bolt (7) running with its ends in elongated holes within the indicator (2). The elongated hole is visible on one side.

Functions of the display means (2) described in Fig.7:

Operating state ON (19)

Large weighing range (20)

Lock released (21)

The arrangement of the individual components can be seen in Fig. 1. The hook (1) encloses the weighing device when not in use. The display device (2) is in the rest position; the electronics are switched off and the handle (3) is locked. If the hook (1) is now folded out, the hook's center of gravity is always automatically vertically under the elastically deformable support (5).

As shown in Fig.3 and Fig.8, the hook (1) and elastically deformable support (5) can be bent by a certain amount

Fig.8 shows the swivel range (23) of the hook (1); Fig.3 shows the swivel range (24) of the elastically deformable carrier (5). The latter is therefore also suitable for holding a strain gauge strip and acting as a measuring element. As shown in Fig.1 and Fig.3, the handle (3) is designed in such a way that it can move freely through 360° in one plane.

The hook (1) consists of a tube section with the diameter of the hook (1); the material is hardened steel or an aluminum alloy with high tensile strength.

It is clear that the weighing device described above with reference to the drawings represents only one embodiment and of course allows for many modifications in structural details within the scope of the inventive concept.
