Definitions

• a pad in particular a mouse pad.
• This invention concerns a pad, and more specifically a kind of pad that enables flexible work with, for example, a mouse, which is used quite widely at present in computer work.
• mouse pad Several kinds of mouse pad are known. Each type has its own advantages and disadvantages and each has tried to solve various problems, most of which are connected in one way or another with work ergonomics. Work at a computer terminal with a mouse can cause quite a lot of different stress injuries, including tendovaginitis and various muscle problems in the neck and shoulder areas.
• a wrist support is used to improve the working position of the wrist, thereby avoiding injuries to the wrist area.
• Other pads are known which provide an opportunity to move the working platform out of the way under the table, for example, when it is not being used.
• Other solutions are known in which the mobility of the wrist support has been improved.
• Finnish patent 92796 exists for a mouse pad. This solution originates from the premise that the mouse pad rests on the user's thigh. For this purpose, the mouse pad has a concave side, which is positioned on the thigh.
• the purpose of this invention is to improve the solutions mentioned above and produce a kind of pad, in particular a mouse pad, which enables a very natural hand position on the thigh while using the mouse.
• a further purpose is to produce a pad, in particular a mouse pad, with which it is possible to move operation to the table if so desired, as the characteristics of a pad according to the invention suit table work as well.
• a further purpose is to ensure that, when situated on the thigh, a pad according to the invention is easily adaptable to an shape of thigh whatever, and that in particular it does not cause sweating while on the thigh, but allows good ventilation and a pleasant feeling.
• An additional purpose is to produce a pad particularly appropriate for use with portable microcomputers, which enables the use of a separate mouse, instead of an integrated mouse of quite poor quality.
• Figure 1 presents one embodiment of the invention in an axonometric diagram
• Figure 2 presents the pad of Figure 1 as seen directly from underneath;
• Figure 3 presents a pad according to the invention as seen from above;
• Figure 4 presents a side view of a pad according to the invention.
• Figure 5 presents an embodiment of the invention, in which it is possible the adjust the positions of the protrusions on the under surface of the base.
• Figures 1 - 4 therefore present a pad according to the invention, and mouse pad 1 in particular, as seen from different perspectives; obliquely from underneath in Figure 1 , directly from underneath in Figure 2, from above in Figure 3 and from the side in Figure 4.
• Pad 1 is formed in the usual way from an essentially smooth, even surface 2, upon which the mouse is intended to move in order to operate the computer.
• the wrist support which can be of any shape whatever, is marked schematically with the reference number 3.
• pad 1 is shaped in such a way that it can be placed on the user's thigh, and can be easily changed back to a regular table mouse pad, when needed, by simply moving the pad to a suitable table surface.
• the under surface of mouse pad 1 according to the invention is basically even. In the embodiment presented, however, the under surface is equipped with four protrusions 4, located so that the pad is supported on the thigh by two protrusions 4 on one side of the thigh and two protrusions 4 on the other side of the thigh. In this way, the pad stays in place and enables the easy, yet functional, use of the mouse with the hand, which is in a very relaxed position resting on the thigh.
• the positioning and form of the protrusions 4 is such that they support the thigh pleasantly from the sides. Should the thigh be narrow, pad 1 presses "deeper” on the thigh, while with wider thighs, the protrusions 4 are supported by the outer sides of the thigh in a higher position. In this way, a pad according to the invention achieves an exceptionally good fit, regardless of the form of the thigh upon which it lies. A pad according to the invention does not form a seal on the thigh, for which reason the pad does not cause sweating.
• the steady working position of a pad 1 according to the invention on the table or other surface is also ensured with the protrusions 4.
• the four protrusions form four support points on the surface. Because these support points are located quite far from each other on the rim of the pad, sturdy placement on tables or other similar surfaces is always successful.
• Figure 5 shows, to a larger scale, one exemplary embodiment of a part of the invention, which only differs from the above in that the protrusions 4 can be set to different positions. It is not, however, intended that the positions are altered every time before use, but rather that the user finds a suitable position, which he will probably be content to use later as well.
• the protrusions there are many alternative ways of attaching the protrusions to the under surface base plate itself.
• One of these is a permanent attachment using adhesiv surfaces.
• the plate 2 and the protrusions 4 are supplied as separate components and paticularly in such a way that the protrusions 4 are equipped with adhesive surfaces protected by removable paper covers or similar. The user finds a suitable position and attaches the protrusions with the aid of the exposed adhesive surfaces.
• a second alternative is to use, for example, a so-called "Velcro" attachment, by means of which a separable attachment is created, giving the possibility of later adjusting the positions of the protrusions by simply tearing the joints apart and re-attaching them in a new position.
• a third alternative could be a pin/hole connection of the kind shown in Figure 5.
• the bold ring 6 symbolizes the pin component, which, in the form shown, retains protrusion 4 in the central position.
• one or other, or both pin components can, if desired, be moved to other holes and thus provide a great deal of variety in the possible adjustments of each protrusion.
• the pin/hole system can be made in any form at all, even in one that permits not only rotational adjustment, but also movement in different directions.
• the pad according to the invention is manufactured from suitable material, such as cellular plastic, with an appropriate manufacturing method. Naturally, other materials can be utilized, particularly plastics in various forms.
• suitable plastic material is polyurethane, for example.
• reinforcements can be added to the material, or appropriate reinforcement projections can be added to the pad at its edges, for example.
• the upper surface of a pad according to the invention can also been covered with a covering material if needed, which allows the ball of the mouse to move around the intended area smoothly, while the wrist support area can be covered to provide a pleasing surface for the wrist, and, if needed, the under surface of the pad can be coated with a material that would prevent sliding and/or sweating.
• the protrusions in the under surface of pad in accordance with the invention can be designed in such a way that their height can be adjusted, for example in such a way that the protrusions are higher when on a thigh than when the pad is placed on a table. In practice, this can be done, for example, by jointing the protrusion at a suitable place, so that the point of the protrusion can be bent to the side for setting it on a table.
• the protrusion telescopes inwards when reasonable force is applied to it and can be re-extended with a suitable pull.
