Definitions
- the invention relates to a protective cover for a handset of a telephone device, such as. B. mobile devices, cordless telephones or the like.
- the handset of the telephone device has a housing which has a plurality of actuatable controls.
- the protective cover at least partially covers the surface of the housing.
- the object of the invention is to provide a protective cover for a hand-held device of a telephone device which can be manufactured inexpensively and can be used quickly and universally. This object is achieved by the protective cover with the features of independent claim 1. Further developments of the invention are presented in the dependent claims.
- the protective cover according to the invention is characterized in that it is designed as a tubular film.
- the protective cover clings directly to the covered surface of the housing of the handset of the telephone device.
- the handset of the telephone device is referred to below exclusively as a handset.
- the protective cover according to the invention largely provides protection against all types of dirt, for example greasy and oily fingers, is water-repellent, can serve as splash protection, offers abrasion protection and is extremely easy to grip.
- a hand-held device which is protected with the protective cover according to the invention, can also be used, for example, by a butcher, a mechanic or the like, who often have dirty hands, without the hand-held device itself becoming dirty or damaged. It is not necessary for these people to wash their hands before operating the handheld device. It is also not necessary to clean the protective cover if it is dirty, it can simply be removed and disposed of and replaced with a new protective cover.
- the protective cover according to the invention is distinguished by its low purchase price, which is preferably in the pocket money range of young people.
- the protective cover according to the invention can be distributed via automatic machines, petrol stations, department store chains or the like, so that the availability of such protective covers is very high.
- Shrink films are also understood as a tubular, preferably thin film in the sense of the application.
- a shrink film can, for example, over a hand-held device can be pulled and then shrunk with a suitable shrinking tool, for example a hairdryer, so that the film conforms to the surface of the hand-held device.
- hand-held devices for telephony devices can be mobile radio devices (cell phones), cordless telephones or similar devices.
- the keys of the keyboard are understood as the operating elements of such devices. However, other types of operating elements can also be present, for example a touch screen with several operating fields.
- the film is open at one end and the other end is closed. In particular, it has a degree.
- the film is preferably first rolled up in itself and can be unrolled over the housing in the manner of a cover (condom). When the film is pulled over, an essentially cylindrical section made of unrolled film material can then form, which encloses the housing of the hand-held device.
- the film preferably has a bead, which is mainly formed by the film material which is rolled up around itself in the original state. After the protective cover has been unrolled over the housing, there is usually a residual bead of excess material that is still rolled up, with which the protective cover on the housing can be additionally secured against automatic rolling up. As a rule, unintentional rewinding is prevented by the film lying tightly against the housing of the hand-held device. The control elements protruding from the housing also prevent such rewinding.
- the residual bead can be pulled over the preferably curved lower end of the hand-held device and tensioned in the process, the holding force being applied in that the annular bead counteracts widening with a relatively large force, which consists of the large number of material layers in this area arises.
- This clamping force is considerably greater than the contact force of the film on the housing and is sufficient to achieve a good fit of the film and, on the other hand, to leave sufficient space on the opening side in order to pass a cable or a plug there.
- the tensioning direction is essentially perpendicular to a direction of pulling over the protective cover parallel to the longitudinal axis of the hand-held device.
- the film has at least one opening with a closed contour.
- the openings can be bushings through which components, such as an antenna, projecting from the housing of the hand-held device can be inserted.
- An IR interface can also be located in the area of an opening so that the signal transmission is not disturbed.
- the openings are expediently at the end of the protective cover. Since in the different types of handheld devices the peripheral components are located in different positions, for example the antenna of a mobile radio device can be arranged on the left, in the middle or on the top right, it is advisable to provide several openings so that the covering of the protective cover is not impaired becomes.
- the outer dimension of the opening can be adapted to the respective peripheral components of the mobile radio device.
- the outer dimension of the opening is preferably smaller than the peripheral component, so that the opening widens when the component is inserted.
- a thickening of the material in particular a reinforced edge, can be provided at the opening.
- the film-like protective cover is preferably designed in such a way that the operating elements, in particular the keyboard, of the hand-held device can be felt and actuated through the film.
- the film can thus nestle against the housing of the hand-held device in such a way that the keyboard keys protrude despite the film overlap and are haptically grasped by the user can. It is therefore possible to operate the handheld device without eye contact. A combination of visual and haptic keyboard operation is also possible.
- the film is in particular designed such that it covers the most important, dirt-sensitive parts of the hand-held device, such as the keyboard, the display element or the like. As mentioned, this can be done by pulling the protective cover over the entire housing with the exception of the peripheral components. However, it is also possible to use a narrow protective cover which is open on both sides and only covers the control element and the display element.
- a film according to the invention preferably consists of a stretchable, in particular elastically stretchable material, which allows it to be stretched to a multiple of its original size.
- the extensibility can be, for example, in the range from 200% to 2000%, in particular 350% to 800% or 1600% of the original expansion. This ensures that the stretchability limit of the film is not reached even with relatively large hand-held devices, thus preventing the film from tearing. This means that all types of handheld devices can be covered with one size of film. Latex, silicone or similar natural materials, plastics or the like are suitable as film material.
- the film can have a material thickening on its outside and / or inside.
- the material thickening can be a relief structure with which information can be reproduced, for example.
- the information for example a name that enables the device to be assigned, is thus both visible and tangible.
- the film is preferably transparent so that the view of the display element, for example a display, or the keyboards is not impaired.
- the film can be colored, so that there are colored distinguishing features of the respective protective sleeves and also enable a device to be distinguished from other devices of the same type.
