DETAILED DESCRIPTION
[0060] FIG. 1a shows a view of a hand-operated self-defense device 1 according to a first embodiment of the invention. The hand-operated self-defense device 1 includes a first strap element 11 for attachment to a palm of a hand, and a second strap element 12 for attachment to a wrist. Further, the hand-operated self-defense device 1 includes a connecting element 2 for connecting the first strap element 11 to the second strap element 12. A defense element 3 is connected to the connecting element 2 or the first strap element 11. The defense element 3 includes a support plate element 4, which includes a plurality of tip elements 5 arranged on the support plate element 4 so as to span a surface. According to the present embodiment, the tip elements 5 are arranged in an annular configuration on the support plate element 4. One of the tip elements 5, in FIG. 1a a tip element 5 located inside the annular arrangement, contains an opening 6. According to this embodiment, the tip elements 5 forming the annular configuration are formed as pyramids. They could also have a cone shape, as shown in FIG. 3. When the opening angle of the cone or pyramid approaches zero, a needle-like structure is formed. The tip elements can therefore also have a needle shape according to an embodiment not shown.
[0061] In particular, the defense element 3 can comprise an evidence collection device 7 for collecting evidence. According to the present embodiment, the opening 6 of the tip element located inside the annular configuration is formed as an evidence collection device 7.
[0062] Evidence, for example tissue cells, hair, body fluids and the like, may accumulate in the opening 6 and remain there after the attack has been repelled by contact with the skin and any injury to the skin of the attacking person that may have resulted from the contact. The tip element or elements 5 may also include an adhesive. By means of the adhesive, adherence of the evidence is enabled so that it remains available even after escape from attack. In particular, a glue may be used as the adhesive. In particular, the adhesive should be inert to solid body particles, such as tissue cells, hairs, or body fluids, so that no chemical reactions can occur with the solid body particles or the body fluids.
[0063] In particular, the first strap element 11 can include a flexible material that can conform to the shape of the wearer's hand. In particular, the second strap element 12 can include a flexible material that can conform to the shape of the wearer's wrist. For example, at least one of the first and second strap elements 11, 12 can include a textile material.
[0064] According to the present embodiment, the second strap element 12 includes a closure mechanism 8 for securing the self-defense device to the wrist. According to the present embodiment, the closure mechanism 8 is configured as a buckle.
[0065] FIG. 1b shows a section through a tip element 5 containing an evidence collection device 7 according to FIG. 1a. The tip element 5 may be configured as a pyramid or a cone containing an opening 6. The tip of the tip element has been removed. According to a particularly advantageous embodiment, the cut surface does not run parallel to the base surface formed by the support plate element 4. Evidence can be received in the opening 6. According to the present embodiment, the opening runs concentrically with respect to the tip element 5, i.e., the center line of the opening 6 coincides with the center axis of the tip element 5. The opening 6 can extend to the support plate element 4 or, according to a variant not shown, can be configured as a blind hole which extends only over part of the total length of the tip element 5. When the tip element 5 is in contact with the skin surface, movement of the tip element 5 along the skin surface may allow evidence in the form of solid body particles, such as tissue cells, hairs, or body fluids to enter and remain in the opening 6. In particular, if the cut surface makes an angle with the base surface that is in the range of 30 degrees up to and including 75 degrees, loose tissue cells may also fall into the opening 6 so that evidence can still be collected even if the skin surface is briefly and lightly touched.
[0066] FIG. 2 shows an application example for the hand-operated self-defense device 1 according to FIG. 1a. According to this embodiment, the hand-operated self-defense device 1 is attached to a hand 9 in such a way that the defense element 3 comes to rest on the palm 10. The defense element 3 includes a support plate element 4 configured to rest on a palm 10. The present arrangement has the advantage that an optimum force transmission can be ensured, since according to the invention the impact force which can be transmitted by means of the palm 10 has proven to be greater in extensive tests than a force transmitted via the back of the hand or the edge of the hand. The force transmission can surprisingly be optimized by the arrangement of the defense element 3 in particular in a central area of the palm 10. Generally, the attacking person does not expect a large force transmission during such a defensive movement, if the defensive movement is triggered by means of the palm of the hand. Therefore, the attacked person can buy time for an appropriate reaction with a pushing movement due to the surprise effect achieved thereby. In particular, the attacked person has more time available for the possibility of escape or for making an emergency call. In addition, the evidence collection device 7 can be used to ensure that solid body particles, such as tissue cells, hair or body fluids of the attacking person remain on the evidence collection device 7 as a result of the pushing movement, often in conjunction with a scratching movement.
[0067] FIG. 3 shows a hand-operated self-defense device according to a second embodiment of the invention. The hand-operated self-defense device 1 includes a first strap element 11 for attachment to a palm of a hand, and a second strap element 12 for attachment to a wrist. Further, the hand-operated self-defense device 1 includes a connecting element 2 for connecting the first strap element 11 to the second strap element 12. A defense element 3 is connected to the connecting element 2 or the first strap element 11. The defense element 3 includes a support plate element 4, which includes a plurality of tip elements 5 arranged on the support plate element 4 so as to span a surface. According to the present embodiment, the tip elements 5 are configured in a multi-row arrangement on the support plate element 4.
[0068] In particular, the defense element 3 can comprise an evidence collection device 7 for collecting evidence. According to the present embodiment, the evidence collection device 7 is arranged between adjacent rows of tip elements 5. The evidence collection device 7 includes an adhesive. For example, an adhesive strip may be used. The adhesive can also be removable and/or replaceable. As described in connection with the preceding embodiment, the evidence collection device 7 can also be formed by at least one of the tip elements 5. The one or more tip elements 5 can also include an adhesive. Solid body particles, for example tissue cells, hairs or body fluids and the like, can accumulate on the evidence collection device 7 and remain there after the attack has been repelled by contact with the skin and a possible injury to the skin of the attacking person caused by the contact. By means of the adhesive, the adherence of evidence is made possible so that it remains available even after the person has fled from the attack. In particular, a glue can be used as the adhesive. In particular, the adhesive should be inert to solid body particles or body fluids so that no chemical reactions can occur with the solid body particles or body fluids.
[0069] In particular, the first strap element 11 can include a flexible material that can conform to the shape of the wearer's hand. In particular, the second strap element 12 can include a flexible material that can conform to the shape of the wearer's wrist. For example, at least one of the first and second strap elements 11, 12 can include a textile material.
[0070] According to the present embodiment, the second strap element 12 includes an elastic material by means of which the hand-operated self-defense device 1 can be fixed in the desired position.
[0071] FIG. 4 shows a section through a tip element 5 containing an evidence collection device 7 according to a first variant. The tip element 5 may be configured as a pyramid or a cone, the tip of which has been removed to gain access to an opening 6. Evidence can be received in the opening 6. According to the present embodiment, the opening 6 is concentric with respect to the tip element 5, i.e., the centerline of the opening 6 coincides with the centerline of the tip element 5. The opening 6 can widen in cross-section from its mouth end to the opposite end resting on the support plate element 4, so that evidence received in the opening 6 remains in the opening 6.
[0072] FIG. 5 shows a section through a tip element 5 containing an evidence collection device 7 according to a second variant. The evidence collection device 7 is again configured as an opening 6, which is located in the jacket area of the tip element 5, which in turn can be configured as a pyramid or cone. This variant has the advantage that the tip of the tip element 5 is retained. Thus, if a minor penetration of the skin of an attacking person occurs by means of the tip element 5, solid body particles, for example tissue cells, hairs, or body fluids, can collect in the opening 6, which can later serve as evidence.
[0073] FIG. 6a shows a section through an evidence collection device 7 according to a third variant in a first position. This evidence collection device 7 is configured as a hollow body, for example a cylinder, with a concentric opening 6 widening in the direction of the support plate element 7. The hollow body contains an elastic material so that the hollow body undergoes a change in shape, for example is compressed, when a compressive force is applied, which is illustrated in FIG. 6b, which shows the section through the evidence collection device according to the variant illustrated in FIG. 6a in a second position. In the first position according to FIG. 6a, the evidence collection device 7 protrudes, for example, beyond the tips shown in one of FIG. 1a to FIG. 3. Therefore, when the evidence collection device 7 comes into contact with the body surface of an attacking person, it is compressed by the applied compressive force. This can result in a suction effect, whereby evidence for identifying the attacking person can enter the opening 6.
[0074] Alternatively or in addition thereto, the evidence collection device 7 may contain an adhesive, for example be coated with a glue. When a compressive force is applied, as shown in FIG. 6b, the surface of the evidence collection device 7 adheres to the body surface of the attacking person. As a result of the adhesive and/or a negative pressure created by the escape of air, solid body particles, for example tissue cells, hair, or body fluids, can thus be picked up as evidence on the surface of the evidence collection device 7 and in the opening 6.
[0075] It is also possible that the opening is partially filled with an adhesive, which only comes into contact with the body surface of the attacking person through the application of the compressive force. According to this variant, the evidence is received in the opening when a defensive blow is made with the hand-operated self-defense device, so that the required compressive force is built up by contact with the body surface of the attacking person and a compression of the evidence collection device occurs. After the compressive force is removed, the evidence collection device 7 is returned to its original shape, as shown in FIG. 6a. The evidence is located in the interior of the opening 6. If necessary, the opening 6 can still be closed later with a plug to protect the evidence from undesirable environmental influences.
[0076] FIG. 7 shows a hand-operated self-defense device according to a third embodiment of the invention. The hand-operated self-defense device 20 includes a first strap element 11 for attachment to a palm of a hand, and a second strap element 12 for attachment to a wrist. Further, the hand-operated self-defense device 1 includes a connecting element 2 for connecting the first strap element 11 to the second strap element 12. A defense element 3 is connected to the connecting element 2. The defense element 3 includes a support plate element 4, which includes a plurality of tip elements arranged on the support plate element 4 so as to span a surface.
[0077] In FIG. 7, the tip elements are covered by a cover 14. As in the previous embodiments, the tip elements may form a multi-row arrangement on the support plate element 4. In particular, the defense element 3 may include an evidence collection device 7 for collecting evidence. On the evidence collection device 7, solid body particles, for example tissue cells, hairs or body fluids and the like, may accumulate and remain after the attack has been repelled by contact with the skin and any injury to the skin of the attacking person that may have occurred as a result of the contact. By means of an adhesive, the adherence of evidence can be enabled or enhanced so that it remains available even after escape from the attack. In particular, a glue can be used as the adhesive. In particular, the adhesive should be inert to solid body particles or body fluids so that no chemical reactions can occur with the solid body particles or body fluids.
[0078] In particular, the first strap element 11 may include a flexible material that can conform to the shape of the wearer's hand. In particular, the second strap element 12 can include a flexible material that can conform to the shape of the wearer's wrist. For example, at least one of the first and second strap elements 11, 12 can include a plastic material. In particular, at least one of the first or second strap elements 11, 12 can include an elastomer such that the hand-operated self-defense device 20 can be fixed in the desired position. According to the present embodiment, the second strap element 12 has a first end that includes a buckle 15. The second strap element 12 has a second end, which is adjoined by an end portion that includes a plurality of recesses 16. The recesses 16 serve to receive an engagement element 18 of the buckle 15. According to this embodiment, the hand-operated self-defense device 20 can be adapted to the wrist of the wearer and is thus designed to be adjustable.
[0079] The first strap element 11 also includes a plurality of hole elements 17. The hole elements 17 serve to receive at least one corresponding pin element 19 (see FIG. 8), which is not visible in the present embodiment because it is arranged on the underside of the first strap element 11. In particular, the pin element or elements may have an oversize with respect to the hole elements 17 so that the pin element or elements are retained in the hole elements 17 when pressed into the hole elements. FIG. 8 shows a side view of the hand-operated self-defense device 20 according to FIG. 7. The side view shows the second strap element 12, its first end with the buckle 15, and its second end. The first strap element 11 is arranged behind the second strap element 12 in this illustration and is therefore not visible. Only the pin elements 19, which are intended to be received in the hole elements 17 shown in FIG. 7, are shown in this illustration.
[0080] FIG. 9 shows a top view of the hand-operated self-defense device 20 according to FIG. 7. Identical or similarly acting components bear the same reference signs as in FIG. 7. The defense element 3 includes a support plate element 4, which includes a plurality of tip elements arranged on the support plate element 4 in such a way that they span a surface. According to the present embodiment, the support plate element 4 is configured to be removable. The defense element 3 includes a receiving element 21 configured to receive the support plate element 4. The support plate element 4, which contains the tip elements 5, can be covered by a cover 14, as shown in FIG. 7. According to this embodiment, the cover 14 is also configured to be removable. In FIG. 9, the cover 14 is shown both in a top view and in a side view.
[0081] FIG. 10a shows a second variant of a support plate element 24, which includes at least one warning element. The support plate element 24 can be used instead of the support plate element 4. The support plate element can contain at least one warning element consisting of the group of acoustic warning elements 25 or optical warning elements 22, 23. The acoustic warning element 25 may comprise, for example, a horn element or bell element by means of which a sound signal having a volume of up to 140 dB may be generated. In particular, the sound signal may have a volume in the range of 125 to 140 db. According to an embodiment, at least one actuating element 26 is provided. The actuating element 26 can be simultaneously configured as the optical warning element 23. According to an embodiment, three actuating elements 26 are provided. The actuating elements 26 can be configured to include a light source, and in particular the actuating elements 26 can simultaneously have the function of illumination and the function as an optical warning element 23.
[0082] The optical warning element 22 can include, for example, at least one light source. For example, the light source can generate white light with a luminous flux of up to 1200 lumens. In particular, the light signal may have a luminous flux in the range of 1000 to 1200 lumens. According to an embodiment, the light source can emit different light signals. For example, light signals with different luminous fluxes or light signals with different colors can be generated by means of the optical warning element 22. In particular, the optical warning element 22 can generate red light. In particular, continuous light signals or discontinuous light signals can be generated. For example, periodic light signals can be generated, in particular light signals with a constant period duration.
[0083] If the actuating element 26 is also configured as an optical warning element 23, the optical warning element 23 can also comprise a light source. According to an embodiment, the light of this light source has a luminous flux of up to 1000 lumens.
[0084] FIG. 10b shows a side view of the support plate element 24. In FIG. 10b, the actuating elements 26 are visible. According to this embodiment, each of the actuating elements 26 can also be used as an optical warning element 23. The optical warning element 23 is configured to emit light in at least two different directions. According to the embodiment shown in FIG. 10b, each of the actuating elements 26 is arranged in a recess 27 of the support plate element 24. By means of the recess 27, it can be ensured on the one hand that the emitted light radiates in different directions, so that the warning signal generated thereby is emitted in more than one spatial direction. Thus, the warning signal is visible from several directions and cannot simply be covered.
[0085] The actuating elements 26 in the arrangement shown in FIG. 10b are also easier to locate, in particular easier to feel in the dark, since the recess 27 can be easily felt with the fingers.
[0086] The support plate element 24 also includes at least one connecting element 28 for attachment in a receiving element 21, as shown in FIG. 9. The connecting element 28 can be configured as a pin element, for example. In FIG. 10b, three pin elements are shown as an example.
[0087] FIG. 11a shows a third variant of a support plate element 34 that includes a pressure vessel 31 for containing a fluid, particularly a liquid. The fluid can comprise an identification means or a repellent means. For example, the fluid can include a dye usable for the purpose of identification. Alternatively or additionally, the fluid can comprise a repellent. In particular, the pressure vessel 31 can comprise a fluid by means of which irritation of the skin may be induced. For example, the fluid can include a pepper spray. The support plate element 34 is shown in a top view. The pressure vessel 31 is closed by a non-visible metering device 32 (see FIG. 11b, FIG. 11d, FIG. 11g) when the support plate element 34 is not in use. The metering device can be activated by means of an actuator 33. The actuator 33 includes an activation element 45, which is intended for activating the support plate element 34.
[0088] FIG. 11b shows a side view of the support plate element 34, wherein the pressure vessel 31 of support plate element 34 is shown in section to reveal the components within the pressure vessel 31. According to this embodiment, the support plate element 34 comprises a pressure vessel 31 shown in sectional view in FIG. 11b. In the operating state, the pressure vessel 31 contains a fluid. The pressure vessel 31 is closed by a metering device 32 when no fluid is to be withdrawn from the pressure vessel 31. The metering device 32 can be activated by means of an actuator 33. The pressure vessel 31 includes at least one connecting element 28 to be fastened in a receiving element 21, as shown in FIG. 9. The connecting element 28 can, for example, be configured as a pin element. In FIG. 11b, three pin elements are shown as an example.
[0089] The metering device 32 includes a fluid receiving element 35, such as a tubular element, see also FIG. 11g, in which the tubular element is shown partially cut open. The fluid receiving element 35 is characterized by a constriction 36 that is fluid impermeable when the metering device 32 is not in use. The constriction 36 may be formed, for example, as a bottleneck. At the constriction 36, the cross-sectional area of a fluid channel extending in the fluid receiving element 35 is zero when the metering device 32 is not in operation as shown in FIG. 11d. Downstream of the constriction 36, the fluid channel widens to form an orifice 37. This orifice 37 is located in a cover element 38, which is attached to a rim of the pressure vessel 31 in a fluid-tight manner. For example, the cover element 38 can encompass the rim 29 of the pressure vessel 31, see also FIGS. 11d, 11e and 11g. The orifice 37 is in particular located in the central region of the pressure vessel 31, according to the present embodiment the orifice 37 is concentric to the center axis of the pressure vessel 31.
[0090] The actuator 33 rests on the metering device 32 and is held in the cover element 38 of the metering device 32 according to the present embodiment, see in particular FIG. 11g. The actuator 33 includes an opening 41 which, when assembled, is aligned with the orifice 37. The opening 41 is configured for expulsion of the fluid form the pressure vessel if the actuator 33 is actuated. An actuator fluid channel 42 extends from the opening 41 to the orifice 37. According to the present embodiment, the actuator fluid channel 42 terminates in the opening 41. A cylindrical channel section 43 adjoins the opening 41, and a conical channel section 44 adjoins the cylindrical channel section 43. The free end of the conical channel section 44 rests on the cover element 38 of the metering device 32 in the orifice 37.
[0091] The actuator fluid channel 42 is arranged in a lid element 46 of the actuator 33. The lid element 46 has a retaining device 47 on its periphery, by means of which the lid element 46 can be retained on the metering device 32. The retaining device 47 may comprise, for example, a bayonet connection, a screw connection or a snap-in connection.
[0092] According to the present embodiment, the activation element 45 is formed as a part of the lid element 46. The activation element 45 comprises a grip element 48 and an inner element 49 containing the actuator fluid channel 42, which is partially separated from an outer portion 50 of the lid element 46 by two slot sections 51, 52. The slot sections 51, 52 are arranged in a kidney shape around the inner element 49 according to an exemplary configuration, see FIG. 11a or FIG. 11f.
[0093] When the actuator 33 is actuated to withdraw fluid from the pressure vessel 31, a compressive force is applied to the grip element 48 of the activation element 45. Since the outer portion 50 and the inner element 49 are connected via a bridge piece 53 located between the two slot sections, a pivotal movement of the activation element 45 takes place relative to the outer portion 50, which is configured as a fixed clamping at the rim 29 of the pressure vessel 31 and the metering device 32 via the retaining device 47.
[0094] The rotational movement of the activation element 45 forces the cylindrical channel section containing the actuator fluid channel 42 and the conical channel section into the orifice 37. This expands the cross-section of the orifice 37 and thus the cross-section at the constriction 36, allowing the fluid in the pressure vessel 31 to pass through the constriction 36, enter the actuator fluid channel 42 and exit through the opening 41. If necessary, the opening 41 can include a nozzle such that a jet of fluid is formed that can exit the support plate element 34 at a high velocity.
[0095] FIG. 11c shows a detail of the actuator 33 of the support plate element 34 shown in FIG. 11a. As described above, the conical channel section 44 is intended to be received in the orifice 37 shown in FIG. 11d. When the channel section is configured as a conical channel section 44, the penetration resistance is low, so that less force must be applied to the grip element 48 to activate the support plate element 34 configured as a fluid dispenser than for a cylindrical channel section. A cylindrical channel section may alternatively be provided but is not shown in the drawings.
[0096] FIG. 11d shows a detail of the metering device 32 of the support plate element 34 shown in FIG. 11a. The metering device 32 includes a cover element 38 and a fluid receiving element 35. The fluid receiving element 35 is configured to form a fluid channel when the support plate element 34 is in the operating state. The support plate element 34 is in the operating state when a user actuates the grip element 48 of the actuator 33, see FIG. 11b, FIG. 11c, and FIG. 11g. In particular, the grip element 48 may be actuated by a finger of the hand on which the hand-operated self-defense device 20 is carried. In FIG. 11d, the non-operating state is shown so that the fluid channel is closed. According to the present embodiment, the fluid receiving element 35 comprises a tubular element which includes a fluid inlet opening 40 which, in the installed state, is arranged in the vicinity of the vessel bottom of the pressure vessel 31. The fluid channel extends through the fluid receiving element 35 from the fluid inlet opening 40 to the orifice 37. In the non-operating state, the fluid channel is closed by a constriction 36 arranged between the fluid inlet opening 40 and the orifice 37.
[0097] FIG. 11e shows a detail of the pressure vessel 31 of the support plate element 34 according to FIG. 11a. The pressure vessel 31 is intended to receive a fluid and, after being filled with the fluid, is closed in a fluid-tight manner by the metering device 32. For example, the rim 29 of the metering device can be fluid-tightly enclosed by a rim receiving element 39 of the metering device. If the pressure vessel is intended for single use, the rim receiving element 39 may be bonded or welded to the rim 29. If the pressure vessel 31 is to be configured to be refillable after use, a sealing element can be included in the rim receiving element, by means of which the escape of the fluid over the rim 29 can be prevented. This variant is not shown in the drawing.
[0098] FIG. 11f shows another top view of the support plate element 34 according to FIG. 11a. The support plate element 34 shown in FIG. 11f is obtained by rotating FIG. 11a by 90 degrees and serves to illustrate the cutting path for the sectional view of FIG. 11g.
[0099] FIG. 11g shows a partial section through the support plate element 34 according to FIG. 11f, wherein the pressure vessel 31 of the support plate element 34 is shown in section to provide a view of the components located inside the pressure vessel 31. In addition, the support plate element 34 is shown in a sectional view in the right half of FIG. 11g to show the course of the fluid channels extending in the metering device 32 and the actuator 33, which provide an exit path for the fluid contained in the pressure vessel 31 in the operating condition. The course of the section is shown in FIG. 11f by the letters A-A and dash-dotted lines. The fluid exit path thus includes the fluid receiving element 35, which includes a fluid channel extending from a fluid inlet opening 40 to the orifice 37 in the metering device 32 and includes the constriction 36. The fluid exit path is not provided until the actuator 33 is actuated in the operating condition. The fluid can flow through the actuator fluid channel 42 in the operating condition, which extends from the end of the conical channel section 44 of the actuator 33 located in the mouth opening 37 to the opening 41 thereof.
[0100] It is obvious to a person skilled in the art that many further variants are possible in addition to the described embodiments without deviating from the inventive concept. The subject-matter of the invention is thus not limited by the preceding description and is determined by the scope of protection defined by the claims. For the interpretation of the claims or the description, the broadest possible reading of the claims is decisive. In particular, the terms “comprising” or “including” are intended to be interpreted as referring to elements, components, or steps in a non-exclusive meaning, thereby indicating that the elements, components, or steps can be present or used, that they can be combined with other elements, components or steps that are not explicitly mentioned. When the claims refer to an element or component from a group that can consist of A, B, C through N elements or components, this phrase is intended to be interpreted as requiring only a single element of that group, and not a combination of A and N, B and N, or any other combination of two or more elements or components of that group.
