- This application claims priority from Patent Cooperation Treaty application number PCT/CH2006/000152, filed Mar. 15, 2006, which claims priority from Swiss patent application number 558/05, filed Mar. 30, 2005
- 1. Field of the Invention
- The invention relates to a walking-stick umbrella as well as a method for engraving a walking stick of a walking-stick umbrella.
- 2. Description of the Related Art
- Walking-stick umbrellas, in particular umbrellas for rain, are not only indispensable articles of daily use in many parts of the world, but are often also a part of the individual image of their users, and are thus dependent on the user's personal sense of taste. As a result, the design of walking-stick umbrellas is dependent not only on the basic purpose—protection in particular against sun or rain—but also on additional aspects of a technical or design nature.
- A particular design of the covering, the walking stick or the grip is intended to make a walking-stick umbrella stand out in a favorable way from the large number of other umbrella models. Walking-stick umbrellas are also popular promotional articles, since on the one hand the covering is a good vehicle for advertising messages and on the other hand users require new walking-stick umbrellas relatively frequently, because the old ones get lost or damaged.
- As an example of a walking-stick umbrella with an additional technical aspect, RU 2,180,793 C2 shows a walking-stick umbrella with a luminous body which can be fitted on the tip of the walking-stick umbrella. The aim is increased safety due to improved visibility at night and in rain. CH 679,266 A5 shows a walking-stick umbrella whose light-transmitting walking stick is illuminated by an incandescent lamp located in the grip. Apart from the favorable effect of increased safety in road traffic due to the improved visibility of the umbrella user at dusk or in darkness, the walking stick capable of being illuminated also makes such a walking-stick umbrella attractive as a gift. A drawback, however, is the rapid exhaustion of the energy carrier, with the aid of which the incandescent lamps are operated. In case of need, therefore, only limited reliance can be placed on problem-free functioning of such a walking-stick umbrella. The reason for the rapid energy exhaustion is, in particular, the simple switching-on and switching-off mechanism of the incandescent lamp, for example in the form of a sliding switch which closes a corresponding electric circuit. If a user forgets to switch off the incandescent lamp after the walking-stick umbrella has been used, the batteries run flat within an extremely short time. If a walking-stick umbrella is folded together after use, the walking stick which may still be illuminated can no longer be seen, and the user is no longer able to notice his oversight.
- It is desirable to make available a walking-stick umbrella, whose walking stick can be illuminated and whose fault-free function is also ensured by means of suitable means over a longer period of time.
- The present invention is a walking-stick umbrella, comprising a grip element, a walking stick and a covering. The walking stick is made from an at least partially transparent or light-transmitting material. The grip element contains an energy storage element, a luminous element with which light can be irradiated into the walking stick, and an electronic device with which the luminous element can be automatically controlled.
- Other objects, advantages, features and characteristics of the present invention, as well as methods, operation and function of related elements of structure, and the combination of parts and economies of deployment, will become apparent upon consideration of the following description and claims with reference to the accompanying drawing, which forms a part of this specification, wherein:
-
FIG. 1 shows a possible design of a walking-stick umbrella according to the invention. -
FIG. 2 a shows a possible design of a grip element of a walking-stick umbrella according to the invention, in longitudinal section. -
FIGS. 2 b and 2 c show a detail of a longitudinal section through a grip element of a walking-stick umbrella according to the invention in a further possible design. -
FIGS. 3 a and 3 b show two variants of a walking stick of a walking-stick umbrella according to the invention, said walking stick provided with graphic elements. -
FIGS. 4 a, 4 b and 4 c show possible variants of a method for engraving a walking stick of a walking-stick umbrella according to the invention. -
FIG. 1 shows a walking-stick umbrella 1 according to the invention, including awalking stick 3 with afirst end 3 a and asecond end 3 b, a covering 4 and agrip element 2. Covering 4 is held taut by means of alinkage 4 b,linkage 4 b being centred onwalking stick 3 by means of aguide element 4 a and being able to be fixed. The arrangement of these elements corresponds to the prior art. -
Walking stick 3 is made of at least partially transparent or light-transmitting material and is essentially rod-shaped, whereby its cross-section can have various suitable shapes, in particular round; oval; with three, four or more corners; and semicircular. A corrugated design ofwalking stick 3 is also possible. -
Grip element 2 serves primarily for holding walking stick 1 and can have various standard design shapes, such as for example the shape of a handle, as in the example shown inFIG. 1 , a cylinder, a knob, or another ergonomically functional shape.Grip element 2 can be produced from polymer, metal, wood or another suitable material. - Arranged in the interior of
grip element 2 of a walking-stick umbrella 1 according to the invention (not visible inFIG. 1 ) is at least one energy storage element, at least one luminous element, and an electronic device. Batteries or rechargeable accumulators, for example with standard size AA (Mignon) or AAA (Micro), can be used as energy storage elements. - The luminous element illuminates transparent or light-transmitting
walking stick 3 fromfirst end 3 a with electromagnetic radiation in the region of the visible spectrum and/or the adjacent infrared and ultraviolet regions. The effect of this is that thewhole walking stick 3 radiates light to the exterior. Polymers, such as for example Plexiglas (polymethylmethacrylate, PMMA), are particularly well suited as the material for producing the walking stick. Other materials can however also be used which, apart from the required light-transmitting properties, possess the required mechanical strength with regard to breaking and bending, which a walking-stick umbrella 3 must possess. The optical impression ofwalking stick 3 is very important, especially whenwalking stick 3 is illuminated, since an attractive appearance of a walking-stick umbrella 1 according to the invention when in use is after all the most important reason for a purchasing decision, i.e. for a favorable emotional effect when a walking-stick umbrella according to the invention is received as a gift. - The walking-stick umbrella can be colored, for example by the addition of pigments and dyes, or it can contain other additives such as for example mica-like materials, metallic or glass particles, etc. Plexiglas rods are available in the trade which have been drawn out during extrusion, which leads to the formation of more or less large drop-shaped cavities. This creates an attractive optical effect when the walking stick is illuminated. When use is made of fluorescent dyes or pigments, it is also possible to cause
walking stick 3 to fluoresce due to irradiation with ultraviolet light (black light). -
FIG. 2 shows in longitudinal section agrip element 2 for use in a walking-stick umbrella 1 according to the invention, said grip element being connected to afirst end 3 a ofwalking stick 3 in a form-fit and/or friction-locked manner. In the example shown,first end 3 a ofwalking stick 3 is inserted into a clampingsleeve 12 and is held in a friction-locked manner by the latter. Screwing or gluing is however also possible. - Clamping
sleeve 12 at afront end 13 a ofgrip element 2 has an opening in the extension of the walking-stick, in which opening aluminous element 5 is disposed. The luminous element preferably comprises a light-emitting diode or another illuminant with a low current consumption. A laser diode can also be used. A plurality of illuminants can also be combined to form aluminous element 5, which in addition can have different colors, so that color mixtures or color changes are possible. Light-emitting diode arrangements can be obtained which comprise a plurality of individually controllable light-emitting diodes integrated in a housing, which can irradiate red, green and blue light. With such luminous elements, light of any color, in particular also white light, can be generated. The light yield, and thus the operational period up to replacement of the energy storage elements, can be further optimized by usingluminous elements 5 with an incorporated reflector. -
Luminous element 5 is operated by means of anelectronic device 7. An operation ofluminous element 5 that is as energy-saving as possible is the primary purpose ofelectronic device 7. In particular,electronic device 7 can switch offluminous element 5 automatically. By means of apushbutton 15 provided on the outside ofgrip element 2, the user can manually instructelectronic device 7 to switch on or offluminous element 5. To advantage, such apushbutton 15 is designed watertight in order to ensure trouble-free operation even when it is raining.Pushbutton 15 can also be replaced by another kind of switch. - In an advantageous embodiment,
electronic device 7 uses a measurement signal from at least onesensor element device 7 is electrically connected. Such measurement signals can be used byelectronic device 7 to controlluminous element 5 according to the current ambient situation and the remaining energy supply in an as energy-efficient manner as possible. - A pressure-
sensitive sensor element 14, such as for example a pressure-sensitive resistor, which is disposed at an outer side ofgrip element 2, can be used to ascertain whether a user is holding the walking-stick umbrella, because then pressure is exerted ongrip element 2 andsensor element 14. - A luminosity-
sensitive sensor element 14 a, such as for example a photo resistor or light/voltage transformer, can be used to determine the ambient luminosity. On the basis of the obtained measured value,electronic device 7 can then regulate the intensity of the light irradiated byluminous element 5 into the walking stick. In particular, the light can be automatically switched on at dusk or the light intensity can be reduced in the presence of very good luminosity conditions, which subsequently also reduces the energy consumption and increases the useful life ofenergy storage elements 6. - In a further advantageous embodiment of a walking-stick umbrella 1 according to the invention, a
sensor 14 b is fitted to walkingstick 3, said sensor being able to register the opening and closing of the walking-stick umbrella. This has the advantage thatelectronic device 7 can switch offluminous element 5 immediately when walking-stick umbrella 1 is closed. Automatic switching-on when the walking-stick umbrella is opened or a short light pulse sequence is also possible. - Various technical variants are possible for the provision of such a
sensor 14 b, for example a Hall sensor, which can register the passing of aguide element 4 a oflinkage 4 b running on the walking stick. For this purpose, guideelement 4 a must be provided with a magnet. Other possibilities are optical or pressure-sensitive sensors 14 b; electrical contacts which are closed with the passage of the guide element or with latching into an end position; or coils which change their inductance with a passage of ametallic guide element 4 a. - It is also possible to equip a walking-stick umbrella 1 according to the invention with a movement or positional sensor. An
electronic device 7 is thus in a position to switch offluminous element 5 in the case of continuous non-movement of walking-stick umbrella 1 or in the case of a continuous non-vertical orientation of walkingstick 3, because then it can be assumed that the walking-stick umbrella has been put down by its user or, for example, has been stored in a luggage compartment or an umbrella stand. Automatic switching-on with reuse may similarly be appropriate. - As already mentioned,
luminous element 5 can be fashioned in such a way that light with at least two colors can be irradiated into walkingstick 3.Electronic device 7 can be equipped in such a way that a time-related variation of the resulting light color and intensity can be achieved. The user can be given an appealing optical impression with such a “play of colors”. - A further possibility is an optical and/or acoustic warning when there is a falling supply voltage of
energy storage elements 6, for example with the warning flashing ofluminous element 5 or with an acoustic signal of a miniaturized piezo loudspeaker. - In the example shown in
FIG. 2 a, twoenergy storage elements 6 are connected in series, which may be necessary in order to achieve the minimum voltage required for the operation of light-emitting diodes or semiconductor components present inelectronic device 7. Various tried and tested solutions, in particular fixing by means of a spring, are known from the prior art for the advantageous mounting of suchenergy storage elements 6, usually batteries or accumulators. Arear part 13 which can be unscrewed permits the replacement ofenergy storage elements 6. The use of a removable holder element, in whichenergy storage elements 6 can be inserted, is also possible. -
FIG. 2 b shows a detail of a longitudinal section throughfront end 13 a of agrip element 2 in a further embodiment. Walkingstick 3 is provided at the end face offirst end 3 a with a recess, which can be produced for example by drilling, milling or smelting. To advantage, the shape of the recess is selected in such a way that aluminous element 5 can be fit as flush as possible. The configuration shown inFIG. 2 b has the advantage that all the light irradiated byluminous element 5 passes into the interior of walkingstick 3, which further improves the energy efficiency. It is also advantageous to apply a reflectinglayer 18 at the luminous-element end of walkingstick 3 and/or in the region of the surface of walkingstick 3 that is located in the interior ofgrip element 2. -
FIG. 2 c shows a possible embodiment of arear end 13 of agrip element 2 for use in a walking-stick umbrella 1 according to the invention.Grip element 2 is provided with additionalluminous elements 5 a, and can be used for example as a pocket lamp. To advantage, the control also takes place by means ofelectronic device 7. In such an embodiment, it is particularly advantageous to designgrip element 2 removable from walkingstick 3. This can be achieved by a reversible fixing ofgrip element 2 to walkingstick 3, for example by means of a screw, plug or bayonet fastening. Such a configuration of a walking-stick umbrella according to the invention has the additional advantage that the user can usegrip element 2 as an independent pocket lamp, for example when it is not raining or when the remainder of the walking-stick umbrella is damaged or is no longer fit for use. - The arrangement of the components of
grip element 2 shown inFIGS. 2 a, 2 b and 2 c is to be understood merely by way of example and can also be designed differently, as long as the technical function is still guaranteed. The example shown ofgrip element 2 is cylindrical. Ifgrip element 2 has a different shape, another arrangement may perhaps also have to be selected for its components. - For the use of walking-stick umbrellas 1 according to the invention as promotional articles or personal gifts, an individual design of
illuminated walking stick 3 is particularly advantageous. Apart from the already mentioned possibilities of an attractive design of the walking stick, it is also possible to applygraphic elements graphic elements material 10 of walkingstick 3, wherebymaterial 10, for example Plexiglas, changes at the focusing point of the laser beam. In the three-dimensional matrix of atransparent material 10, a visible dot emerges in the form of a small non-transparent, whitish volume. Two- or three-dimensional patterns can be produced by suitable displacement of the focusing point, such as are shown for example inFIGS. 3 a and 3 b.FIG. 3 a shows on the left in a parallel projection a short section of awalking stick 3 for use in a walking-stick umbrella 1 according to the invention. In the interior of the walking stick, agraphic element 16 in the form of the lettering “Werbung” is laser-engraved inmaterial 10. On the right inFIG. 3 a, thesame walking stick 3 is shown in plan view onto the longitudinal axis of the walking stick. Laser-engravedlettering 16 lies in a plane in the centre of the walking stick. When walkingstick 3 is illuminated byillumination element 5, the irradiated light is scattered at the laser-engraved sites, which as a result looks as though the lettering is shining. - A word or picture mark, a logo, a company name or the name of a person to be presented with a gift, for example, can be used as
graphic element 16. Depending on the use, laser-engraving can be used in mass production or in the manufacture of single units to produce a personalized gift. -
FIG. 3 b shows that three-dimensional graphic elements are also possible. Firstgraphic elements 16 a are located in a first plane, and secondgraphic elements 16 are located in a second plane. - In the production of
graphic elements walking sticks 3, the problem arises that alaser beam 17 is broken when it strikes the surface of awalking stick 3. If this surface is not a plane, as is the case for example with walking sticks with a round cross-section, the laser beam cannot be focused on a single point in the matrix ofmaterial 10. Laser-engraving is therefore not readily possible in such cases. -
FIG. 4 a illustrates schematically an advantageous method, by means of which laser-engraving can also be carried out withwalking sticks 3 with a cylindrical shape. In order to compensate for the non-plane surface of walkingstick 3 to be laser-engraved and to enable focusing oflaser beam 17, anirradiation element 8 is applied onto the surface of walkingstick 3. The surface ofirradiation element 8 is provided complementary to the surface of walkingstick 3, so that between walkingstick 3 andirradiation element 8 there is, as far as possible, no cavity which can have an adverse effect on the focusing.Irradiation element 8 has a plane surface at its end opposite to walkingstick 3. Alaser beam 17 is irradiated throughirradiation element 8 into walkingstick 3 and focused on a specific point. In order to achieve the smallest possible refraction oflaser beam 17 in the transition frommaterial 10 a ofirradiation element 8 intomaterial 10 of walkingstick 3, and thus also the smallest possible misfocusing oflaser beam 17, the refractive indices of the twomaterials irradiation element 8, therefore, a material 10 a should be selected whose refractive index does not differ by more than 5% from the refractive index ofmaterial 10 of walkingstick 3. More advantageously, the difference amounts to 1% or less. This can be achieved in the simplest way by selecting as similar a material as possible for bothmaterials - With laser-engraving of the type discussed, the object to be engraved advantageously has two parallel, plane surfaces. In order to achieve this advantageous configuration also with
walking sticks 3 with a round cross-section, a reflectingelement 9 is applied onto the surface of walkingstick 3 on the side lyingopposite irradiation element 8, as shown inFIG. 4 b. Once again, reflectingelement 9 and walkingstick 3 should have surfaces as complementary as possible. The same conditions as already discussed above forirradiation element 8 apply to the refractive index ofmaterial 10 b of reflectingelement 9. - The introduction of a liquid 11 between the surfaces of
irradiation element 8 and walkingstick 3, or between reflectingelement 9 and walkingstick 3, is also possible, as shown inFIG. 4 c. Losses oflaser radiation 17 due to reflection are thus further reduced. To advantage, the refractive index ofliquid 11 in turn lies as close as possible to the refractive indices of theother materials List of reference numbers: 1 walking- stick umbrella 2 grip element 3 walking stick 3a first end 3b second end 4 covering 4a guide element 4b linkage 5, 5a luminous element 6 energy storage element 7 electronic device 8 irradiation element 9 reflecting element 10 material of walking stick 10a material of irradiation element 10b material of reflecting element 11 liquid 12 clamping sleeve 13 rear end 13a front end 14, 14a, 14b sensor element 15 switching-on element 16, 16a graphic element 17 light beam 18 reflecting layer
