Description

COVER AND METHOD FOR MANUFACTURING A COVER
BACKGROUND OF THE INVENTION
[0001] The invention relates to a cover and a method for manufacturing a cover according to the independent claims.
[0002] Electronic devices, particularly portable devices such as mobile stations, wrist computers, palmtop computers, mp3 players and cameras, may be subjected to very big stress, such as distortion and impacts, during use. A problem is that the cover of an electronic device is often provided with a user interface element sensitive to damages, such as a display, which does not withstand the stress applied to the cover during the use.
BRIEF DESCRIPTION OF THE INVENTION
[0003] It is an object of the invention to provide a cover, which protects a user interface element attached thereto from mechanical stress during use. It is also an object of the invention to provide a method for manufacturing such a cover that protects a user interface element attached thereto from mechanical stress during use.
[0004] The objects of the invention are achieved by a cover and a method, which are characterized by what is disclosed in the independent claims. The preferred embodiments of the invention are disclosed in the dependent claims.
[0005] The invention is based on integrating into the cover an elastic frame means, which is arranged to connect the user interface element elas- tically to the cover part, by an injection moulding process.
[0006] The cover of the invention provides the advantage that the user interface element is fastened elastically to the cover part, whereupon mechanical stress applied to the cover part cannot be transferred with all its force to the user interface element. The advantage of the method of the invention is its simplicity and low costs.
BRIEF DESCRIPTION OF THE FIGURES
[0007] The invention will now be described in greater detail in connection with preferred embodiments and with reference to the attached drawings, in which
Figure 1 shows a cover according to an embodiment of the invention; Figures 2A to 2C show cross sections of elastic frame means according to alternative embodiments of the invention; and
Figures 3A to 3C and Figure 4 show elastic frame means according to different embodiments of the invention.
DETAILED DESCRIPTION OF THE INVENTION
[0008] Figure 1 shows a mobile station cover according to an embodiment of the invention, comprising a cover part 2 and an elastic frame means 6. The elastic frame means 6 comprises a body 61 , which is attached to the cover part 2 by spring elements 10.
[0009] The body 61 of the elastic frame means comprises a substantially planar and rectangular section and four corner protrusions 63, each of which extends outwards from the corresponding corner of the rectangular section substantially parallel to the corresponding diameter of the rectangular section. The outermost end of each corner protrusion 63, i.e. the end that is furthest from the rectangular section of the body, is separated from the cover part 2.
[0010] A display to be attached to the cover, the location of which is illustrated by a broken line 41 in Figure 1 , is fastened to the corner protrusions 63 of the elastic frame means 6 by suitable fastening means, which may comprise quick clamping elements, double-sided adhesive tape or glue, for instance. To protect the display, it is possible to mount a window element which is made of glass or plastic and may be fastened to the cover part 2 by using ultrasonic or laser welding, adhesive tape or glue.
[0011] Figure 1 shows that the spring elements 10 of the elastic frame means 6 extend to a bigger area than the display to be mounted in the frame means. Thus, the display does not entirely cover the spring elements 10. The outermost parts of the spring elements 10 may be covered entirely, for instance, by a window element, whose parts that are located further out than the display surface are darkened or coloured in some other way. The outermost parts of the spring elements 10 and also of the corner protrusions 63, if needed, may also be covered by a separate covering element, which may be placed on top of or under the window element. The covering element may be made of plastic or metal, for example.
[0012] The display is fastened to the cover of Figure 1 after the injection moulding processes. If a cooled and substantially pressure-free auxil- iary chamber were provided for the display during the injection moulding process, the display could be attached to the cover part in the same injection moulding process in which the cover part is manufactured.
[0013] The spring elements 10 are substantially planar, and they extend in the same plane with the body 61 of the elastic frame means. Each spring element 10 is substantially V-shaped so that one end of the spring element 10 is fastened to the body 61 of the elastic frame means and the other end to the cover part 2. Each spring element 10 is directed in such a manner that the tip of V points outwards, i.e. to the closest corner protrusion 63. On each of the four sides of the elastic frame means 6 there are spring elements 10 pointing in the opposite directions.
[0014] The elastic frame means may be arranged in such a manner that with respect to the cover part, it allows for the user interface element fastened to the frame means a particularly large elastic movement parallel to the critical plane, the user interface element being most sensitive to impacts in this direction. In other words, the elastic frame means may be arranged so that its spring constant is substantially smaller parallel to the critical plane than in the direction perpendicular to the critical plane.
[0015] In the cover of Figure 1 , the spring elements 10 are arranged to provide elasticity primarily parallel to the plane of the frame means 6. This spring direction is selected as primary, because in the finished product the display surface of the display to be mounted in the cover of Figure 1 is parallel to the plane of the elastic frame means 6 and because a typical display is most sensitive to impacts in the plane of the display surface.
[0016] The elastic frame means 6 is integrated into the cover part 2 in an injection moulding process. According to an embodiment of the invention, the elastic frame means is made of the same injection moulding material as the cover part 2 in the same injection moulding process.
[0017] According to an alternative embodiment of the invention, the elastic frame means is made of a different injection moulding material than the cover part, whereby the material of the elastic frame means may be selected so that its elasticity is substantially better than that of the cover part material. A substantially more elastic material allows the use of smaller spring elements, because the elasticity of the elastic frame means with respect to the cover part may be largely provided by the elasticity of the material, and not only by the geometry of the spring element. The elastic material may be, for instance, an elastomer or a thermoplast such as polypropylene or polycarbonate or polyethylene. When the cover part and the elastic frame means are manufactured in different injection moulding processes, their integration into one another may be achieved by using either one or both of the above mentioned injection moulding processes.
[0018] According to another alternative embodiment of the invention, the elastic frame means is made of metal and integrated into the cover by injection moulding the cover part. It is also possible to combine above- mentioned embodiments, for example, so that the elastic frame means is made partly of metal, partly of the same injection moulding material as the cover part. This may be implemented by placing the metallic part of the elastic frame means into a mould for the injection moulding process of the cover part. The elastic frame means may comprise metallic spring elements connected with the injection-moulded body of the elastic frame means. The cover part may also consist of more than one material. For example, metallic parts may be embedded in the cover part by placing the metallic parts into an injection mould.
[0019] In embodiments, where the cover is made of two or more injection moulding materials or where a prefabricated frame means is placed into an injection mould, significant deformations may take place in the frame means during the injection moulding, which are caused by different thermal expansion, thermal shrinkage or tensions of different materials. Disadvantages caused by these deformations in the frame means may be prevented by shaping the spring elements in such a manner that they are elastic in those directions in which mechanical stress occurs during the injection moulding. In this case, potential deformations at the outer edge of the elastic frame means cannot be transferred to the body.
[0020] Problems caused by different thermal expansion of the materials may also be reduced by minimizing the amount of such materials in the cover, the thermal expansion properties of which considerably differ from those of the principal materials of the cover. For example, an elastic frame means, in which only the spring elements are made of metal and the body of the elastic frame means is made of an injection moulding material, is less problematic in terms of thermal expansion differences than an elastic frame means made completely of metal. [0021] The elastic frame means of the cover of Figure 1 is a planar object, in which both the body 61 of the elastic frame means and the spring elements 10 extend in the same plane. Figure 2 shows three alternative embodiments, in which spring elements 110, 210 and 310 also extend in a direction perpendicular to the plane defined by the body 61. In the embodiments of Figure 2, the body 61 of the elastic frame means is planar, and it may have the same shape as the body 61 shown in Figure 1. In Figures 2A to 2C, the elastic frame means according to the alternative embodiments are shown in cross section from the side, i.e. seen from the direction along the plane of the body 61.
[0022] In the embodiment of Figure 2A, the spring element 110 has a U-shaped cross section so that its ends are in the same plane with the plane defined by the body 61 of the elastic frame means and the arc of U extends downwards from said plane. In the embodiment of Figure 2B, the spring element 210 has a V-shaped cross section so that its ends are in the same plane with the plane defined by the body 61 of the elastic frame means and the tip of V extends downwards from said plane. In the embodiment of Figure 2C, the spring element 310 has a cross section of a cut V so that the end of V on the side of the body 61 is lower than the end of V on the side of the cover part 2 and the tip of V extends downwards from the plane defined by the body 61 of the elastic frame means.
[0023] Figure 3A shows an alternative embodiment of the elastic frame means from the direction of the normal of the plane defined by the body of the frame means. There are four spring elements 10' on each side of the elastic frame means 61. The spring elements 10' are substantially planar, and they extend in the same plane with the body 61. Each spring element 10' comprises a substantially U-shaped part, where the arc of U points inwards, i.e. to the centre of the corresponding side of the body 61. The user interface element is fastened directly to the body 61. There are no corner protrusions.
[0024] Figures 3B and 3C show another alternative embodiment of the elastic frame means. Figure 3B shows the frame means from the direction of the normal of the plane defined by its body, and 3C shows it obliquely from above. On each side of the body 61 of the elastic frame means there are four spring elements 10".
[0025] Figure 3B shows that each spring element 10" comprises a part, which, seen from above, is substantially U-shaped and where the arc of U points inwards, i.e. to the centre of the corresponding side of the body 61. The arc of U of the spring elements 10" shown in Figure 3B has a substantially larger curvature than the arc of U of the spring elements 10' shown in Figure 3A. The elastic frame means of Figure 3B does not comprise corner protrusions, which means that the user interface element is fastened directly to the body 61.
[0026] Figure 3C shows that the spring elements 10" also extend perpendicularly to the plane of the body 61 of the elastic frame means in such a manner that the outer edge 62 of the elastic frame means, which is arranged to be fastened to the cover part, is located higher than the body 61.
[0027] In the above embodiments, the body of the elastic frame means is rectangular, and it is arranged to receive a rectangular display. Alternatively the body of the elastic frame means may be round, oval or polygonal, for instance. The body of the elastic frame means need not be planar either. The user interface element to be connected to the body of the elastic frame means need not be rectangular or planar either.
[0028] The location of the body of the elastic frame means in the depth direction, i.e. in a direction perpendicular to the plane of the body, may be dimensioned based on the thickness of the display to be used and the height at which the upper surface of the display is to be placed with respect to the surrounding cover part.
[0029] The cover shown in Figure 1 is arranged to be provided with one display, which is fastened to the elastic frame means 6. In an alternative embodiment of the invention, the same elastic frame means is provided with two displays on the opposite sides of the frame means in such a manner that the display surfaces point to the opposite directions. Such a structure may be used for example in a clamshell phone, in which the first of said displays is on the inner surface of the cover, which can only be seen when the phone is folded to the open position, and the second display is on the outer surface of the cover and can also be seen when the phone is folded to its closed position.
[0030] Figure 4 shows an example of a frame means provided with two displays, wherein a display 401 is fastened to the upper surface of the body of the elastic frame means and a display 402 is fastened to the lower surface of the body of the elastic frame means.
[0031] The elastic characteristics of the elastic frame means are preferably based not only on the elasticity of the material of the elastic frame means but also on the mechanical spring element structures according to Figures 1 to 4. By changing the length, thickness, shape and number of spring elements of the elastic frame means, elastic characteristics suitable for different devices may be achieved, the material of the spring elements remaining the same. For instance, when user interface elements of different weights are fastened to different production series of covers, in connection with heavier user interface elements the spring elements of the elastic frame means may be made wider and thus more rigid than in other production series by using suitable injection moulds.
[0032] In addition to a display, the user interface element to be fastened to the cover by the elastic frame means of the invention may in the above examples be, for instance, a keyboard or some other element by which data may be transferred between the device and the user.
[0033] In this context, a cover refers generally to a component, which is arranged to constitute at least a part of the surface of the device attached thereto. The cover may be a replaceable or fixed cover. A replaceable cover refers to a cover which is arranged to be replaced by the user. A fixed cover, on the other hand, refers to a cover which is not arranged to be replaced by the user.
[0034] It is obvious to a person skilled in the art that the basic idea of the invention may be implemented in various ways. The invention and the embodiments thereof are thus not restricted to the above examples but may be varied within the scope of the claims.
