Continuing the sloped edge surface 7 of the thicker part, the first casing part 1 has a thinner part 9, which has a relatively large inner surface 10, on which a selection key 12 is provided. A selection operation surface 11 with an LED display section 13, as well as further display means and operation means, such as a speaker volume adjustment section 14, are provided. The second casing part 2 is provided with a four-part part 16 on its inner surface 15, in which a folded edge part 17 formed in the shape of a one-armed lever is provided with a second part 16.
It is supported so as to be pivotable or foldable in the direction shown by the arrow in the figure. Furthermore, the second housing part 2 is provided with a symbol record carrier 18, which is also movable in the direction indicated by the arrow in FIG. This symbol record carrier 18 can be completely stowed away in the second housing part 2. The first casing part l is also provided with a transmitting and receiving antenna 19, which can be pulled out and pushed in the direction shown by the arrow in FIG. It is preferable to provide a claw 19' at the tip for easy handling. Behind the surface 20 of the folding part 17, which is also provided with the acoustic holes 5, there is a microphone arrangement, which is not shown, which can be folded together. Shown in solid lines in FIG. 2 is the telephone in the working position, in which the first and second casing parts 1.2
The oblique end faces 1' and 2' of the two are in contact with each other. When both casing parts 1 and 2 are folded together (the casing part 2 in this position is indicated by a dashed line), the casing part 2 reaches the thin part 9 of the first casing part 1, and finally the rectangular shape of the handheld type is formed. 1 is stopped. In this case, the end face or edge 1.2' on the side of the pivot axis lies in the plane indicated by the dash-dotted line, thereby forming the upright plane 21;
Using this stand surface, the phone closed together can be placed upright on a desk, for example.

Figures 4 and 5 show details of the telephone. It is shown that the first casing part 1 is made up of a bottom part 1a and a top part 1b, which are fixedly connected to each other by fitting, welding, screwing, etc. A speaker 22 is mounted behind the surface 6 of the thick portion. bottom 1
Attached to a is an electronic circuitry 23 in the form of a diode-1 matrix circuit with a coding capacity of approximately one million pairs. In the cutout 24 in the area of the thin part 10, a shielding frame 10a for the selection keys of the operating surface 11 as well as the display (for example 13) and other operating means (for example 14) can be fitted. There is a hole 25 in the lower abutment edge 1'
, and behind this hole there is provided a connecting member, generally designated 26, for example a connecting plug, which part is conductively connected to a charging device (not shown) for the current supply of the telephone. Ru. Reference numeral 27 denotes a short shaft-shaped stop portion, which is formed on the bottom portion 1a, to which, for example, a circuit configuration group, a selection key, etc. can be attached. Similar to the first housing part 1, the second housing part 2 essentially consists of a bottom part 2a and a top part 2b, which are designed, for example, as plastic molded parts and are fixedly joined to one another. The upper part 2b has a pastazo-shaped forming surface 28.
Four parts 16 are provided which are partially partitioned downward by a folding part 17, into which a folding part 17 can be fitted. The folding part 17 is formed into a substantially U-shape, and has a side surface 17a and a short axis 1 formed on this side surface 17b.
7b, in which case the short axis 17 is fixed by the slit 17C.
b has enhanced elasticity and spring characteristics. This short axis 17
b is engaged with the shaft hole 29 in both side walls of the forming surface 28, and the members 17b and 29 then serve as the pivot axis of the folding part 17. As shown in FIG.
has transverse webs 30, 31, 32 on the back side, with a microphone capsule 33 mounted between the transverse webs 31 and 32, and the transverse web 30 serving as an actuating element for a push switch 34. A push switch operating mechanism 34' is present in the path of movement of the folding section 17. This push switch 34 is used for turning on/off the functional devices of the telephone, in particular for turning on/off the dialing device and the microphone. The bottom part 2a is divided into two tufts by a transverse web, and a battery support frame 37 is inserted into the tuft 36 from below and is locked to the second casing part using the locking protrusion 38 of the support frame. can do. This battery support frame 37 forms a housing portion for the current supply device of the telephone.

A biaxial hinge member 39 is used as a pivot for both casing parts l and 2, which is inserted into the bearing hole 4o in the upper part 1b of the first casing part 1 and engaged at the thickened end of this member. will be stopped. A protrusion 41 of the shielding frame 10a is further used to lock the hinge member 39, and this protrusion is engaged, for example, between directly adjacent hinge members (at the position inserted into the bearing hole). . As shown in FIG. 4, an Ω-shaped pressure spring 42 is provided in the area of the aforementioned pivot axis, the ends of which are gripped by projections 43.44 of the two casing parts 1.2. . These projections are arranged at a distance from the pivot axis and are arranged at an angular position of approximately one-half of the angle between the end face or abutment edge 1 or 2 and the adjoining inner surface 10 or 15. . As a result, a lever arm is provided between the pivot axis and the gripping point of the pressure spring 42 both in the ready position and in the closed position, by means of which the housing parts 1 and 2 are pressed together by spring force in the plane position. When closing, that is, when closing the casing part 2 together, the pressure spring 42 first bends back to a neutral intermediate position or dead center position, and when the casing part 2 is further closed, a force is applied in the opposite direction by this piezoelectric spring. In other words, the casing part 2 is elastically pressed against the inner surface 10 of the casing part 1 at the position indicated by the dashed line in FIG. In this case, due to the force of the pressing spring 42, the folding part 17, which is pressed by a spring (not shown) to the usable position, that is, the operating position, moves into the recess 16 of the casing part 2.
Then, the folding portion 17 is press-fitted until its surface becomes flush with the inner surface 15 of the casing portion 2.

During the closing movement of the folding section 17, the push switch 34 is operated to the cutoff position. Conversely, in the working position, the housing parts 1, 2 are fixed by the pressure spring 42 in the position shown in solid lines in FIG. In this position, the folding section 17 is moved to the open position by the pressure spring of the folding section, whereupon the push switch 5
4.34 is fixed or held after being moved to the closing connection position. As shown in FIG. 5, a notch 19 is provided at the corner of the bottom portion 1a of the first casing portion 1.
An antenna (not shown) can be inserted here and pulled out from here using the claw 19. FIG. 4 further shows a battery support frame 37, on which three rod-shaped batteries 45 are supported in the embodiment.

6, 7, 7a, and 8 are diagrams showing the battery support frame and the terminal springs for the battery electrodes. As also shown in FIG. 5, the battery support frame, also formed, for example, as a synthetic resin molded part, has three battery storage compartments 46, 47.
It has 48. Terminal springs are provided in the end partitions of the storage compartments 46 to 48 in the form of pressure springs 49 and 50, the pressure spring 49 being shown as a single piece in FIG. 7a. The pressure spring consists of two spring parts 9a wound in a spiral shape and having a height of, for example, four angles, and a connecting part 49b that electrically connects them to each other. Similarly, the pressure spring 50 also consists of two cylindrical spring parts 50a and a connecting part 50b extending between them, and this connecting part 50b is attached to a spring holder 51 formed in the battery support frame 37. It is being

Both spring portions 50a are provided on opposite end faces of storage compartments 48 and 47. In this way all batteries 4
5 can be easily connected in series. The battery 45 abuts against a longitudinally extending protrusion 52 of the battery support frame 37 and is held in the correct position in the storage compartment by a cover 53.

An electrical terminal 54 is fixed to one end face of each of the storage compartments 46,48.

Effects of the Invention The radiotelephone according to the invention as claimed in claim 1 can consist of relatively few parts, for example two foldably interconnected function-casing parts, which The two parts are supported relative to each other both in the closed rest position and in the open working position by means of simple spring-loaded elements.
