The invention relates to holding apparatus for supporting and connecting an industrial mobile device, wherein the mobile device has a flat body and comprises at least in the portions used for holding a pair of oppositely located parallel sides. At one of the sides of the device an industrial-type connector plug is arranged, and the holding apparatus can be connected to a suspension assembly and comprises a holding unit that can be releasably attached to the oppositely located holding side where the device is held. The holding unit comprises a friction hinge and a support block connected both to the hinge and the device.
The use of computers, tablets, mobile phones and other smart devices has become indispensable part of our life in practically all areas of activities. This is especially true for different professional applications when such devices are necessary components of everyday work. Work is done not only in offices with indoor circumstances but also under outdoor conditions, in the field with rough circumstances when users require their both hands to carry on. The holding, arrangement and handling of such devices must be ensured also under such conditions to attain that the weight required for their holding be as small as possible and the reliability, protection and comfort of use should be at maximum.
The hard field circumstances may happen under military, police, security, industrial and sport activities, and to such purposes specially designed devices have been developed that comprise water- and shock proof cases and connectors. In the present specification such devices are referred to simply as “industrial devices” which include tablets, mobile phones and other electronic devices equipped with a display to which often different peripheral accessories should be connected. The term peripheral accessory covers reserve battery packs, different electronic field units, ad handling devices which can be used only when connected to the industrial device. The user should wear the industrial device on his/her body, possibly at the region of the chest to leave both hands free, however, during use for watching the display the device must be able for being turned near right angle to the chest of the user. The turning of the device changes in most of the cases the length of the cables leading to the peripheral devices that impose a pulling or pushing force on the concerned cable which might has an adverse effect on the safety of the connection and can lead to cable-breakage or disruption of the wires in the cables. Against such adverse effects up to the present the solution was the increase of the size and weight of the connectors and cables.
In field, sport and free time apparels the use of MOLLE/PALS clothing has become more and more spread using poches and straps. Such clothes can be seen e.g., in US 2007/0289045 A1 that are provided with tongues having special designs with a fully bent end parts that can be tucked into pouches made by special straps, and different utensils and gears can be held thereby. Many of the modern industrial and free time sports outfits are equipped with such pouches and straps.
The publication US 2013/0258573 provides a solution for holding and connecting industrial devices wherein on a holding tongue a specially designed hinge is arranged that can be suspended in the pouches of a MOLLE clothing and the hinge is attached to the wide side of the rectangular device more precisely to the case of the device, and the electrical connections are solved by a separate block forming part of the case and arranged at the short side of the device, wherein the connection to the peripheral units was made by a vertically extending cable as the connector was fixed to the bottom of the block. The inside of the block provide space for the positioning of electrical components required for the connection but the manipulation there is rather difficult. In that solution the hinge allowed for the device to be folded out to take a horizontal position but during such a turning the initially vertical position of the connection cable changed to take a horizontal direction, whereby the free length of the cable has become shorter and has also been bent by 90°, causing a substantial mechanical load thereon. In the vertical holding position a separate member is used to connect the device with the suspension assembly that renders the forward bending difficult, and its use requires a separate mechanical step and attention.
There exist hinges that can be turned only under the application of a predetermined torque which are generally referred to as “torque hinges”, which will be called in the present specification as “friction hinges” or simply hinges because the required torque is provided by friction forces within the design of the hinge.
A further much more robust and heavy solution for the connection of the device is described in WO 2021/041647, in which the holding of the device (called there as control center) is provided along the longer side and the electrical connection takes place also at the shorter side connected with the drawbacks outlined before.
The task of the invention is to provide a holding apparatus for such industrial devices that has smaller volume and space than the afore mentioned systems and can provide a more reliable connection of the cable or cables and provides an easier handling.

Reference is made now to the enlarged sectional view of
The profile of the connector plug 36 fixed to the bottom side 35 of the device 30 is just the complementary of the profile of the socket 22, wherein corresponding to the two edges 24a, 24b at the two sides there are respective inward steps, and opposite to the swelling sections 26a, 26b there are nests 37a, 37b. The contact surfaces of the connector plug 36 required for the electrical connections terminate at the horizontal surfaces between and beside the nests 37a, 37b and they press against the oppositely located spring-biased contacts 27. These contact surfaces are located slightly deeper than the swelling sections 26a, 26b.
The socket 22 in the support block 3 and the connector plug 36 at the side of the device 30 have conforming and fitting profiles and such conforming profiles limited at the two sides by the edges 24a, 24b and in the intermediate portion by the swelling sections 26a, 26b cooperate with the receiving nests and provide a very stable support and form-fitting reception for the device 30, therefore there will be no need for using further receiving and supporting parts. This form-fitting connection can be released only if the device 30 is raised from the support block 3. The dimensions shown ensure that no forces can act on the sensitive contact until the two fitting parts get into engagement, since the connector plug 36 can be moved in downward direction only after it has been fitted into the socket 22.
In the hollow interior of the support block 3 components 28 required for the electrical connections are arranged when fixed in a suitably designed printed circuit board 29, and they ensure proper connection of the two connectors 11, 12.
The number and the type (negative or positive) of the contacts in the connectors 11, 12 are determined by the properties of the peripheral units connectable to the device 30 and by the requirements imposed against these units.
A common property of the embodiments described that the holding arrangement 1 can receive the device 30 with minimum additional weight and volume, whereas the load imposed on the connection cables and connectors is at minimum, and the insertion and removal of the device 30 is simple but very stable and durable, therefore it satisfies the requirement imposed to devices used under field circumstances.
