Abstract

The invention is a device for drying racket handles, especially tennis racket handles, and entails a rotational plate and a fan unit designed to blow warm air against the plate (2). The rotational plate (2) is designed to support the end of the tennis racket (7) and is formed at the base by a cylindrical housing or a covering (1). The plate (2) is rotational during warm or cold air bursts to the handle (8) from at least a single fan (5,6) located in the cylindrical housing (1) aimed to the centre or interior drying area (18) and equipped with heat coils. The covering (1) has an inner length that from the support surface (9) of the plate (2) corresponds at least to the handle's (8) length and an inner width or diameter that is greater than that of the handle. An opening (11) to receive the handle (8) is located at the upper end of the covering (1) centrally above the rotational plate (2). A handle (8) moistened by sweat can be dried quickly and effectively during a moment of rotation in the warm air streaming through the housing's (1) drying area (18).<IMAGE>

Description

15 20 25 30 4471341 2 övre del i huvudsak mitt ovanför den roterbara plattan, var- vid ett av svett fuktat eller nedblött handtag snabbt torkas under en stunds roterande i den genom höljets torkutrymme strömmande varmluften. Upper part substantially in the middle above the rotatable plate, whereby a handle moistened by sweat or soaked is quickly dried for a while rotating in the hot air flowing through the drying space of the housing.

Tack vare föreliggande uppfinning har nu en anordning åstad- kommits med vilken torkningen av handtaget på speciellt ett tennisracket kan ske på mycket kort tid, ca 60 s, till och med om handtaget doppats i vatten dvs är genomvått. Genom att racketen bringas att rotera under torkningen och att tempera- turen på varmluften och torktiden är reglerbar kan individuel- la önskemål erhållas samtidigt som det läder som användes på handtaget icke torkar sönder eller tar skada på annat sätt. _Vidare erhålles en mycket effektiv torkning i höljets torkut- rymme genom att torkluften bringas att rotera inuti detsamma.Thanks to the present invention, a device has now been provided with which the drying of the handle on a tennis racket in particular can take place in a very short time, about 60 s, even if the handle has been dipped in water, ie is soaked. By making the racket rotate during drying and that the temperature of the hot air and the drying time are adjustable, individual wishes can be obtained at the same time as the leather used on the handle does not dry or be damaged in any other way. Furthermore, a very efficient drying is obtained in the drying space of the casing by causing the drying air to rotate inside the same.

Genom torkanordningen åstadkommes även att spelaren spar sin kraft till själva spelet istället för såsom fallet varit ti- digare mycket kraft åtgâtt till att försöka hålla ett stadigt och säkert grepp om ett blött racket.The drying device also ensures that the player saves his power for the game itself instead of, as has been the case in the past, a lot of force being applied to try to keep a firm and secure grip on a wet racket.

Uppfinningen beskrives närmare nedan under hänvisning till bifogade ritning, vilken visar ett föredraget utföringsexem- pel av en torkanordning enligt föreliggande uppfinning, sett i en schematisk tvärsektion.The invention is described in more detail below with reference to the accompanying drawing, which shows a preferred embodiment of a drying device according to the present invention, seen in a schematic cross section.

Såsom framgår av figuren består torkanordningen enligt upp- finningen av ett cylinderformst hus eller hölje 1, i vars bottenparti finns en centralt anordnad roterbar platta 2 med en bäryta 9. Plattan 2 kan bringas att rotera medelst en mo- tor 3, vilken roterbart uppbär plattan 2 via en axel 4. En undre fläkt 5 och en övre fläkt 6 är anordnade inuti höljet 1 och har luftintag 14 resp 15 för friskluft samt på ritning- en icke visade inblåsningsmunstycken, vilka är mynnande tan- gentiellt i ett rackethandtaget 8 upptagande utrymme 18. Bär- ytan 9 på plattan 2 är avsedd att mottaga änden av ett ten- nisrackethandtag 8 och åstadkommer en så stor friktion mot handtaget 8 att detta bringas att rotera tillsammans med 10 15 20 25 30 35 3 447 341 plattan 2 vid torkningen. Medelst fläktarna 5 och 6 kan bå- de varm- och/eller kalluft blâsas mot handtaget 8 allt efter inställning av en till dessa kopplad termostat 19. Höljet 1 har en längd som från plattans 2 bäryta 9 motsvarar ungefär 3/4 av skaftets 10 längd och torkutrymmet har en bredd eller diameter som är något större än diametern på handtaget 8.As can be seen from the figure, the drying device according to the invention consists of a cylindrical housing or housing 1, in the bottom part of which there is a centrally arranged rotatable plate 2 with a bearing surface 9. The plate 2 can be caused to rotate by means of a motor 3, which rotatably supports the plate 2 via a shaft 4. A lower fan 5 and an upper fan 6 are arranged inside the housing 1 and have air intakes 14 and 15, respectively, for fresh air and in the blowing nozzles (not shown in the drawing), which open into a racket handle 8 receiving space 18 The support surface 9 of the plate 2 is intended to receive the end of a tennis racket handle 8 and causes such a large friction against the handle 8 that it is caused to rotate together with the plate 2 during drying. By means of the fans 5 and 6, both hot and / or cold air can be blown against the handle 8 depending on the setting of a thermostat connected to them 19. The housing 1 has a length which from the bearing surface 9 of the plate 2 corresponds to approximately 3/4 of the length of the shaft 10. and the drying space has a width or diameter which is slightly larger than the diameter of the handle 8.

Mitt ovanför den roterbara plattan 2 är en öppning 11 anor- dnad i höljet 1 för införande av handtaget 8 i torkutrymmet 18. Strax under öppningen 11 finns ett ljusrelä 12, vilket är kopplat till motorn 3 och fläktarna 5 och 6 via ett tid- relä 13, varvid motorn 3 och fläktarna 5 och 6 med värme- slingor automatiskt kan startas vid införandet av en rack- etände genom öppningen 11, eventuellt med någon tidsför- dröjning så att torkningen startar t ex först efter att rackethandtagets 8 ände vilar mot plattans 2 bäryta 9. Tid- reläet 13 kan även vara inkopplat mellan ljusreläet 12 och fläktarna 5 och 6 med värmeslingorna och motorn 3, så att de automatiskt stängs av efter ca 50 - 60 s, då handtaget 8 är torrt eller då detta lyfts upp ur torkutrymmet 18 och passerar ljusreläet 12. Fläktarnas 5 och 6 värmeslingor är termostatstyrda så att mängden värme i den luft som insprutas i torkutrymmet 18 är steglöst reglerbar, varvid man bl a förhindrar att lädret på handtaget 8 spricket eller torkar sönder. Den roterande plattan 2 har formen av an tallrik med en runt sin periferi kontinuerligt förlöpande kantfläns 16 i och för centrering av ett på denna placerat rackethandtag 8. Plattan 2 kan även vara försedd med en korg 17, vilken sträcker sig från bärytans 9 periferi vertikalt upp genom torkutrymmet 18 ända upp till ett område strax under öppning- en 11. Denna korg 17 är avsedd för lägesfixering av racket- handtaget 8 då detta befinner sig för roterande torkning i torkutrymmet 18.In the middle above the rotatable plate 2, an opening 11 is arranged in the housing 1 for inserting the handle 8 into the drying space 18. Just below the opening 11 there is a light relay 12, which is connected to the motor 3 and the fans 5 and 6 via a time relay. 13, whereby the motor 3 and the fans 5 and 6 with heating loops can be started automatically when a rack end is inserted through the opening 11, possibly with some time delay so that the drying starts for example only after the end of the rack handle 8 rests against the plate 2 bearing surface 9. The time relay 13 can also be connected between the light relay 12 and the fans 5 and 6 with the heating coils and the motor 3, so that they are automatically switched off after about 50 - 60 s, when the handle 8 is dry or when it is lifted out of the drying space 18 and passes the light relay 12. The heating coils of the fans 5 and 6 are thermostatically controlled so that the amount of heat in the air injected into the drying space 18 is infinitely adjustable, whereby, among other things, the leather on the handle 8 is prevented from cracking or drying broken. The rotating plate 2 is in the form of a plate with an edge flange 16 extending continuously around its periphery in order to center a racket handle 8 placed thereon. The plate 2 can also be provided with a basket 17, which extends vertically up from the periphery of the support surface 9 through the drying compartment 18 all the way up to an area just below the opening 11. This basket 17 is intended for fixing the position of the racket handle 8 as it is for rotary drying in the drying compartment 18.

Anordningen enligt uppfinningen fungerar på följande sätt: När det är paus stoppar spelaren ned racketens 7 skaft 10 med handtaget 8 genom öppningen 11 i torkanordningen, var- ulf- 447 341 efter torkningen startar. Då pausen är slut och spelet ska fortsätta eller tidigare om andra åtgärder måste göras på racketen och minst den inställda tiden ca 40 - 60 s gått, har torkaren automatiskt stängts av, varvid erhålles ett fullständigt torrt handtag 8 på racketen 7 och ett fullgott grepp om handtaget 8 kan således upprätthållas. Skulle av någon anledning racketen 7 lyftas upp tidigare ur torkut- rymmet 18 stängs torkanordningen automatiskt av då skaftet 10 passerat ljusreläet 12 vid öppningen 11.The device according to the invention works as follows: When there is a pause, the player stops the shaft 10 of the racket 7 with the handle 8 through the opening 11 in the drying device, whereupon 447 341 after drying starts. When the break is over and the game is to continue or earlier if other measures must be taken on the racket and at least the set time about 40 - 60 s has elapsed, the wiper has been switched off automatically, resulting in a completely dry handle 8 on the racket 7 and a full grip on the handle 8 can thus be maintained. Should for any reason the racket 7 be lifted earlier from the drying space 18, the drying device is automatically switched off when the shaft 10 has passed the light relay 12 at the opening 11.
