DETAILED DESCRIPTION OF THE FIGURES

[0054] Turning to figures 1 to 7, an embodiment of a portable handheld device 1 is shown. The device 1 is intended and configured for reducing, in particular preventing, direct hand 13 contact with an external object 2. The device 1 comprises a main body 3 comprising an elongate hollow member 4.

[0055] The device may have rounded corners. Rounded corners allow the device to be cleaned effectively. Rounded corners also allow for less accumulation of dirt and bacteria.

[0056] The device may have rounded edges. Rounded edges are comfortable for a user his or hers hand.

[0057] The device 1 can be used with a single hand.

[0058] The hollow member 4 comprises a first end 5, an opposite, second end 6, an inner surface 7, and an outer surface 8. A longitudinal gap 9 is provided in the hollow member 4. The longitudinal gap 9 extends from the first end 5 to the second end 6, and from the inner surface 7 to the outer surface 8.

[0059] The longitudinal gap 9 is configured as an insert opening 10 for an elongate external object 2, as shown in for example figures 3 and 4 wherein the elongate external object 2, as an example, is a door handle 71.

[0060] The inner surface 7 of the hollow member 4 defines an internal volume 11 for accommodating the elongate external object 2. The inner surface 7 of the hollow member 4 is configured to contact an external surface 12 of the elongate external object 2. The outer surface 8 of the hollow member 4 is configured to be contacted by the hand 13 of the user, in particular the palm of the hand, as shown in figure 4. The shape of the hollow member 4 provides a large outer surface 8 for the user to contact. A large outer surface 8 is desired, because it provides protection and comfort in many situations.

[0061] The hollow member 4 is resilient, or flexible. A first side 14 of the hollow member 4 adjacent the longitudinal gap 9 and an opposite, second side 15 of the hollow member 4 adjacent the longitudinal gap 9 are movable towards and away from each other by deformation of the hollow member 4.

[0062] Having the first and second side 14, 15 move away from each other allows the insert opening 10 of the device 1 to be moved over an elongate external object 2 having a greater diameter than the initial gap width 23 of the longitudinal gap 9.

[0063] Having the first and second side move towards each other allows the device 1 to enclose an elongate external object 2 having a smaller diameter than the initial gap width 23 of the longitudinal gap 9. The first and second side may also slide over each other, thereby further decreasing the internal volume 11.

[0064] The first and second side 14, 15, may also be used to grip an object between said sides 14,15 by moving them towards each other.

[0065] The hollow member 4 has a length 18, a width 19 and a height 20, wherein the length 18 is at least twice the width 19 and/or at least twice the height 20.

[0066] As shown in the front view of figure 5 a circumferential length 21 of the longitudinal gap 9 is between 0.15 and 0.3 times a circumferential length 22 of the hollow member 4.

[0067] In said front view of figure 5 the longitudinal gap 9 has a gap width 23 which is between 0.25 and 0.5 times the width 19 of the hollow member 4.

[0068] In front view the device 1 has a C-shape 55. The hollow member 4 has a C-shape 55.

[0069] In the shown embodiment the hollow member 4 has an, in front view, oval shape 56 with a side opening 57. Other shapes are also possible, like for example a circular or polygonal shape with a side opening 57.

[0070] An inner diameter 58 of the hollow member 4 is between 15 and 55 mm, in particular between 25 and 45 mm.

[0071] As shown in the side view of figure 6 the bottom end 73 is curved. The bottom end 73 gradually curves upwards from a central part 24 towards the first end 5 and second end 6. The curved bottom end 73 helps in moving the insert opening 10 of the hollow member 4 over an elongate external object having a larger diameter than the insert opening.

[0072] As shown in figure 7A a gap width 23 of the longitudinal gap 9 varies along the length 18 of the hollow member 4. The longitudinal gap 9 is narrowest at a central part 24 of the device 1. The longitudinal gap 9 tapers outwardly when travelling from the central part 24 towards the first end 5 and end second end 6. This arrangement has as an advantage that the device 1 is easier to slide over the elongate external object 2.

[0073] Figure 7B schematically shows a wall thickness 25 of the hollow member 4. The wall thickness 25 is between 1-3mm.

[0074] An edge 26 extends around the outer circumference of the hollow member 4. The edge 26 has an edge thickness 27 which is greater than the wall thickness 25 of the tubular member. The thicker edge 26 improves grip for the user. The thicker edge 26 also enables the user to feel when he or she has reached the end of the outer surface 8 of the device 1.

[0075] The main body 3 comprises a first coupling member 28 for coupling the device 1 to a retaining unit 29.

[0076] The first coupling member 28 is provided at the first end 5 of the hollow member 4 and extends away from the tubular member in a longitudinal direction 30 thereof.

[0077] The first coupling member 28 comprises a left hook part 31 and an opposite, right hook part 32. A first end 33 of the left hook part 31 and a first end 34 of the right hook part 32 are connected to the hollow member 4. A free, second end 35 of the left hook part 31 and a free, second end 36 of the right hook part 32 extend away from the hollow member 4 and towards each other.

[0078] The first end 5 of the hollow member 4, the left hook part 31 and the right hook part 32 define a coupling gap 37 for accommodating a corresponding second coupling member 38 of the retaining unit 29, as shown in an assembly 100 according to the invention in figure 9.

[0079] A first gap 39 is provided between the free, second ends 35, 36 of the left hook and the right hook. The first gap 39 has a first gap width 40, see figure 7B.

[0080] The first gap width 40 is smaller than a thickness of a second coupling member 38 of the retaining unit 29. This way, once coupled, the device 1 can only be uncoupled from the retaining unit 29 upon the exertion of an external force. The device 1 will not simply fall out of the retaining unit 29.

[0081] The left hook part 31 and the right hook part 32 are resilient. The free, second end 35 of the left hook part 31 and/or the free, second end 36 of the right hook part 32 are movable towards and away from one another for decreasing or increasing the first gap width 40.

[0082] The free, second ends 35, 36 of the left hook part 31 and the right hook parts 31, 32 are rounded at an inner side 42 thereof facing the hollow member 4 and at an outer side 43 thereof facing away from the hollow member 4. The rounded ends help guide the second coupling member 38 of the retaining unit 29.

[0083] The first coupling member 28 comprising the hook parts allows the user to uncouple the device 1 from the retaining unit 29 quickly. A quick uncoupling is beneficial, because when the user experiences the quick use the user will use the device 1 more often. When the use of the device 1 increases, the chance of contamination decreases.

[0084] The main body 3 comprises a first protrusion 44 provided at the first or second end 6 of the hollow member 4. In the shown embodiment the first protrusion 44 is provided at the second end 6. The first protrusion 44 is intended and configured to be pushed against an external surface 12. External surfaces can for example be buttons of an elevator, a train door or a traffic stopping light, buttons of an ATM, or simply a doorbell.

[0085] The first protrusion 44 comprises a curved plate 45 that is connected at the first or second end 6 of the hollow member 4. The curved plate 45 extends parallel to the hollow member 4. In the shown embodiment the curved plate 45 is a continuation of a top surface 72 of the hollow member 4.

[0086] The first protrusion 44 comprises a hook part 46 configured for pulling on an object. The hook part 46 is provided at a lateral side of the first protrusion 44. In the shown embodiment the first protrusion 44 comprises two hook parts 46, one at each lateral side. The hook allows for a pulling action. Examples where the first protrusion 44 is useful are lifting a toilet seat or opening the lid of a refrigerator.

[0087] The main body 3 comprises a second protrusion 47 extending from the hollow member 4 at the first or second end 6 thereof, wherein the second protrusion 47 is provided at a distance 48 from the first protrusion 44 and extends parallel to said first protrusion 44.

[0088] The second protrusion 47 is provided at an opposite end of the hollow member 4 as the first protrusion 44.

[0089] The first protrusion 44 is located on a first side 49 of a longitudinal axis 30 of the hollow member 4, when seen in top view.

[0090] The second protrusion 47 is located on a second side 50 of the longitudinal axis 30, when seen in top view.

[0091] The main body 3 comprises a through hole 52 for connecting a connector 53 or a retaining unit 29 thereto.

[0092] The through hole 52 in the shown embodiment is provided in the first protrusion 44. The through hole 52 may also be provided at the first or second end 6 of the hollow member 4, or partly at the first or second end 6 of the hollow member 4 and partly in the first protrusion 44.

[0093] Turning to figure 8 the device 1 is shown comprising an electrically conductive unit 51 for pressing and operating a touch screen. The conductive unit 51 is made from a material comprising electrically conductive properties. In an embodiment the material is a thermoplastic elastomer comprising electrically conductive carbon.

[0094] The conductive unit 51 is located at the same end of the hollow member as the second protrusion 47. In top view the conductive unit 51 extends beyond the second protrusion 47.

[0095] The electrically conductive unit 51 may be provided as a connector 53. The device 1 as shown figure 8 comprises the connector 53, and the connector 53 comprises the electrically conductive unit 51 for pressing and operating the touch screen.

[0096] The device 1 is substantially symmetric, in particular symmetric, in top view and/or in bottom view about a plane 54 defined by the longitudinal axis 30. The symmetry allows the device 1 to be used easily by both a right hand 13 and a left hand.

[0097] The outer surface 8 of the hollow member 4 is textured. The texture improves the grip of the user.

[0098] The device 1 is a single body. A single body simplifies the manufacturing process, as for example a single mould can be used when the device 1 is made by injection moulding.

[0099] The device 1 is made from a low-density polyethylene material. This material is durable and provides both strength and resilience.

[0100] The material of the device comprises an anti-microbial additive. The anti-microbial additive has as an advantage that the time microbes remain on the surface of the device 1 is drastically reduced. The multiplication of contagious microbes is prevented by the additive. The amount of anti-microbial additives may be 1-5 wt%.

[0101] Turning to figures 9 and 10 an assembly according to the invention is shown. The assembly comprises the device 1 and a retaining unit 29. The retaining unit 29 is coupled to the device 1 via the first coupling member 28.

[0102] It is also possible that the retaining unit 29 comprises the first coupling member 28. In that case the device 1 can also be coupled to the retaining unit 29 via the through hole 52.

[0103] The device 1 is removable from the retaining unit 29 by pulling the device 1 away from the retaining unit 29, as shown in figure 10.

[0104] The device 1 is can be coupled to the retaining unit 29 by pushing the first coupling member 28 or the through hole 52 of the device 1 through or over a second coupling member 38 of the retaining unit 29.

[0105] In the shown embodiment the retaining unit 29 comprises a second coupling member 38 configured to be coupled to the first coupling member 28 or the through hole 52 of the device 1.

[0106] The second coupling member 38 is defined by a through hole 59.

[0107] As mentioned above, the retaining unit 29 may have a second coupling member 38 which is similar to the first coupling member 28 comprising the left and right hook parts 31, 32. In that case the second coupling member 38 of the retaining unit 29 can be coupled to either the first coupling member 28 or the through hole 52 of the device 1.

[0108] Turning to figures 11 and 12, an embodiment of a retaining unit 29 is shown. A thickness 67 of the second coupling member 38 is greater than the first gap width 40.

[0109] The retaining unit 29 comprises a hook 70 at an opposite end thereof. The hook can for example be attached to a belt holder of a user his trousers, or to a bag. This way the device 1, when coupled to the retaining unit, is in close range for the user to uncouple it from the retaining unit 29 and to quickly use the device 1.
