Abstract

The map winder according to the invention provides the possibility of quick use of preset maps (2) which can have no pulling strings (27), standard five single level winding spindles (10) or pulling strings (27) featuring five single level or nine two-level winding spindles (10). On the support of the winding spindles (8) and (9), which are at the distance determined by the distance elements (6) attached by screws (7) to the lathe (4), there are winding spindles with wound maps (2), with its individual wound location determined by fastening a tooth (32) on the freely swinging locking notch (15), inside the groove (33) on the locking ring (13), which is non-rotatingly connected to the non-rotating spindle axis (11). The winding of the map (2) is provided by a prestressed coil spring (17), which is by its bent side (42) inserted into the groove (20) of the non rotating spindle axis (11), while its other end (18) it is inserted to the opening (39) of the rotating pipe end bracket (14). The extreme position to which a map (2) can be wound by a map winder with pulling strings (27) is adjustable according to the position of the ball (30) of the pulling string (27), which leads through the open coil loop (43) on the limiter (28), attached to the winding spindles support (9).

Description

Predmet izuma je navijalnik za zemljevide, kateri je v izvedbi brez poteznih vrvic in z enovišinsko namestitvijo navijalnih vreten, ter v izvedbi s poteznimi vrvicami in z enovišinsko ter dvovišinsko namestitvijo navijalnih vreten.The subject of the invention is a map winder, which is provided without a drawstring and with a single-height installation of winding spindles, and in a design with a drawstring and with a single-height and two-height installation of winding spindles.

Po mednarodni patentni klasifikaciji sodi izum v ...According to the international patent classification, the invention belongs to ...

Tehnični problem, ki ga rešuje izum, je takšna konstrukcija navijalnika za zemljevide, ki je stalno nameščena v prostoru npr. v učilnici in ima na navijalnih vretenih navite zemljevide, katere lahko pri dovolj nizki postavitvi na zid direktno z ročnim potegom za zemljevide te odvije ali zavije, dočim jih pri višjih postavitvah odvijamo ali zavijamo s poteznimi vrvicami.A technical problem solved by the invention is the construction of a map winder, permanently mounted in a space, e.g. in the classroom, and has winding maps on winding spindles that can be unwound or twisted directly by manually pulling the maps at sufficiently low wall placement, while unwinding or twisting them with higher ropes at higher layouts.

Dosedaj še nismo zasledili nobene rešitve za neko mehanizirano prikazovanje zemljevidov na principu navijalnika za zemljevide, ampak samo posamezno obešanje zemljevida na steno ali tablo.So far we have not found any solution for some mechanized map rendering on the map retractor principle, but just a single hanging of the map on a wall or board.

Dosedanji način uporabe pri prikazovanju zemljevidov je zelo neprikladen, ker vsakokratna uporaba zahteva stalno skrb za iskanje, prinašanje in nameščanje, za kar se uporabi mnogo časa, pri nameščanju se pojavljajo pogoste poškodbe zemljevidov, kar skrajšuje življenjsko dobo uporabe.The current usage of map rendering is very inappropriate, as each use requires constant search, retrieval and installation care, which is time consuming, with frequent damage to the maps during installation, which shortens the life of the map.

V principu podobna rešitev mehanizma za odvijanje in zavijanje se uporablja pri roletah iz tkanine.In principle, a similar solution for the unwinding and wrapping mechanism is used for fabric shutters.

Rešitev problema po izumu zahteva sicer stroške nabave navijalnika za zemljevide, vendar s tem odpadejo vse skrbi glede iskanja, prinašanja, nameščanja in skladiščenja zemljevidov.Solving the problem of the invention does require the cost of purchasing a map winder, but it eliminates all the hassle of finding, retrieving, installing, and storing maps.

Po izumu je problem rešen z navijalnikom za zemljevide, ki ima prednostno pet ali devet navijalnih vreten, v katerih so vstavljeni in naviti želeni zemljevidi, katere pri uporabi za prikazovanje odvijemo oziroma navijemo pri umaknitvi in to z direktnim potegom zemljevida z roko ali s pomočjo potezne vrvice.According to the invention, the problem is solved with a map winder, which preferably has five or nine winding spindles, in which the desired maps are inserted and wound, which, when used for display, are unscrewed or wound upon withdrawal by direct pulling of the map by hand or by means of a pull twine.

Izum bo podrobneje opisan na izvedbenem primeru v več variantah in slikah, katere prikazujejo:The invention will be described in more detail in the embodiment in several variants and figures, showing:

Navijalnik za zemljevide brez poteznih vrvic, namenjen za nižjo postavitev na steno, kjer so na navijalna vretena 10 naviti zemljevidi 2 s tal dosegljivi z roko, je prednostno izveden s petimi navijalnimi vreteni 10, katera so nameščena horizontalno v isti višini in enaki medsebojni oddaljenosti pod okvir 1, katerega sestavljata dve stranski letvi 4, dve vzdolžni letvi 5 in pokrov 3, kar je razvidno na sl. 1, sl. 2, sl. 3 in sl. 4.A map retractor without drawstrings intended for lower wall mounting, where winding maps 10 from the ground are accessible by hand, is preferably made with five winding reels 10, which are arranged horizontally at the same height and at the same distance below each other. frame 1, consisting of two side slats 4, two longitudinal slats 5 and a cover 3, as shown in FIG. 1, FIG. 2, FIG. 3 and FIG. 4.

Namestitev posameznega navijalnega vretena 10 pod okvir 1 in njihova konstrukcijska rešitev je za izvedbo navijalnika za zemljevide s potezno vrvico 27 ali brez nje enaka, kar je prikazano na sl. 5.The placement of each winding spindle 10 under frame 1 and their design solution is the same for the implementation of the map winder with or without the drawstring 27, as shown in FIG. 5.

Na levi in desni stranski letvi 4 sta za distanco distanČnika 6 z vijaki 7, pritrjena nosilca navijalnih vreten 8 in 9, na katera so vstavljena navijalna vretena 10. Na posameznem navijalnem vretenu 10 je zunanji pokrov 12 in zaporni obroč 13 nerazdružljivo fiksno vezan na os vretena 11, dočim je zaključni vložek cevi 14, kateri je fiksno vezan s cevjo 21, vrtljiv pa okrog osi vretena 11, vendar aksialno zaradi vskočnika 19 nepremičen. Navijalno vreteno 10 ima na eni strani v cev 21 tesno vstavljen zaključni čep 26, kateri je z izstopnim okroglim delom 40 vrtljiv v okrogli izvrtini 41 na nosilcu navijalnega vretena 9, na drugi strani pa je sploščeni del 25, na osi vretena 11, vstavljen v izrezan utor 32 na nosilcu navijalnega vretena 8, kamor vstavljena os vretena 11 ni vrtljiva.On the left and right side slats 4, for the distance of the spacer 6 with screws 7, the holders of the winding spindles 8 and 9 are attached, to which the winding spindles 10 are inserted. of the spindle 11, to the extent that the end insert of the tube 14, which is fixedly connected to the tube 21, rotates about the axis of the spindle 11, but is axially fixed due to the lug 19. The winding spindle 10 has a tightly inserted end cap 26 on the one side of the tube 21, which is rotatable in the round bore 41 on the winding spindle bracket 9 on the outlet round portion 40, and on the other side a flattened part 25 on the spindle axis 11 inserted in a notched groove 32 on the winding spindle carrier 8, wherein the inserted spindle axis 11 is not rotatable.

Zaključni vložek cevi 14 ima na dveh simetričnih mestih iz središčnice osi navijalnega vretena 10 dve z osjo paralelni izvrtini 38, v kateri sta vstavljena zatiča z glavo 16, okrog katerih vrtljivo nihata zaporna jezička 15, od katerih se vsaj eden, v slučaju mirovanja vrtenja navijalnega vretena 10, z zobom 32 zatakne v utor 33 na zapornem obroču 13 in tako onemogoči samodejno navijanje, v katerem koli mirujočem položaju navitega zemljevida 2.The end pipe insert 14 has two symmetrical points from the center line of the axis of the winding spindle 10 two axis parallel to the bore 38, in which are inserted the pins with the head 16, around which the locking tabs 15 are rotated, at least one of which, in the case of a rotation of the winding rotation. the spindle 10, with the tooth 32, is stuck in the groove 33 on the locking ring 13, thus preventing automatic winding in any stationary position of the wound map 2.

Vrtilni moment, potreben za navijanje zemljevida 2, je dosežen z vgrajeno prednapeto dolgo vijačno vzmetjo 17, kjer je en upognjen konec vzmeti 18 vstavljen v izvrtino 39 na zaključnem vložku cevi 14, kateri je vezan na vrtljivem delu navijalnega vretena 10, drugi upognjen konec vzmeti 42 pa je vstavljen v utor 20, ki je na osi vretena 11, katera se pri vrtenju navijalnega vretena ne vrti.The torque required for winding Map 2 is achieved by a built-in prestressed long helical spring 17, where one bent end of the spring 18 is inserted into a bore 39 on the end insert of the pipe 14, which is tied to the rotating part of the winding spindle 10, the other bent end of the spring 42 is inserted into the groove 20, which is on the axis of the spindle 11, which does not rotate when the winding spindle is rotated.

Posamezen zemljivid 2 se pred montažo zaključnega čepa 26 vstavi pri odprtem vzdolžnem ravnem izrezu cevi 22 tako, daje zgornja letev 23 na zemljevidu 2 vstavljena v cev 21. Pred montažo posameznega navij alnega vretena 10 na nosilca navij alnih vreten 8 in 9, mora biti zemljevid 2 navit, os vretena 11 pa se nekoliko zavrti v smeri navijanja vzmeti 17, kar daje določeno prednapetost oziroma potreben vrtilni moment za navijanje.The individual map 2 is inserted prior to mounting the end plug 26 in the open longitudinal straight cutout of the pipe 22 so that the top lath 23 on the map 2 is inserted into the pipe 21. Prior to mounting the individual winding spindle 10 on the winding spindle supports 8 and 9, the map 2 is wound, and the axis of the spindle 11 rotates slightly in the direction of the winding of the spring 17, which gives a certain prestress or the necessary torque for winding.

Navijalnik za zemljevide brez poteznih vrvic 27 ima na sredini pod pokrovom 3, na njega prečno po širini, pritrjeno letev 34, katera se z odvitjem krilne matice 35 iz vijaka 36 hitro sprosti, zavrti okrog vrtišča 37 za kot 90° levo ali desno, kar omogoča hitro zamenjavo posameznih navijalnih vreten 10 z navitimi zemljevidi 2, prikazano na sl. 2, sl. 3 in sl. 4.The map retractor without the drawstring 27 has a lath 34 fastened centrally beneath the cover 3, transversely to the width 3, which is rapidly released by unscrewing the wing nut 35 from the screw 36, rotating about 90 ° left or right around the pivot 37 enables rapid replacement of individual winding spindles 10 with winding maps 2 shown in FIG. 2, FIG. 3 and FIG. 4.

Nadaljno vrtenje že navitega zemljevida 2 v slučaju pobega, onemogoči letev 34, v katero zadane spodnja letev zemljevida 48, tako se prepreči sprostitev prednapetosti vijačne vzmeti 17, katera je potrebna za normalno navijanje in preprečijo se možne poškodbe zemljevida 2.Continued rotation of the already wound map 2 in the event of an escape will disable the lath 34 into which the lower lath of the map 48 defines, thus preventing the pre-tensioning of the coil spring 17, which is required for normal winding, and preventing possible damage to the map 2.

Navijalnik za zemljevide s potezno vrvico 27 ima enako konstrukcijsko rešitev navijalnega vretena 10, enaka je njihova montaža na nosilca navijalnih vreten 8 in 9, kakor tudi enaka je pritrditev teh na stranskih letvah 4, kar je že prej opisano za navijalnik za zemljevide brez poteznih vrvic 27. Razlika je le v tem, da ima navijalnik za zemljevide s potezno vrvico 27 na vsakem navijalnem vretenu 10, vpeto in navito potezno vrvico 27, s pomočjo katere lahko zaradi visoke namestitve navijalnika za zemljevide odvijemo in navijemo posamezen zemljevid 2. Navedena izvedba navijalnika za zemljevide ima dodatno omejevalec 28, kateri je prednostno izveden iz jeklene žice, pritrjen na spodnji del nosilca navijalnih vreten 9 in nameščen v vertikalni osi obodne linije navite potezne vrvice 27 na posameznih navijalnih vretenih 10.The map retractor with drawstring 27 has the same structural design of the winding spindle 10, the same mounting on the support of the winding spindles 8 and 9, as well as the attachment of these on the side rails 4, as previously described for the retractor for maps without drawstring 27. The only difference is that the map retractor with a drawstring 27 has on each winding spindle 10, a twisted and retracted drawstring 27, by means of which a single map can be unscrewed and wound due to the high positioning of the map retractor. for maps, there is an additional stop 28, preferably made of steel wire, attached to the lower part of the winding spindle carrier 9 and positioned in the vertical axis of the circumferential line of the winding pull line 27 on individual winding spindles 10.

Omejevalec 28 je v delu vodenja vrvice 27 oblikovan v odprto spiralno zanko 43, katera zaradi pritrjene krogle 30 na določenem položaju potezne vrvice 27, omogoči omejevanje navijanja in s tem določi zgornji položaj navitega zemljevida 2. Odprta spiralna zanka 43 na omejevalcu 28, omogoči enostavno vstavljanje in snemanje potezne vrcice 27 v in iz vodilne zanke, kar je potrebno izvesti pri namestitvi in snemanju navijalnih vreten 10 v in iz navijalnika za zemljevide.The limiter 28 is formed into an open helical loop 43 in the guide portion 27 of the rope, which, due to the fixed ball 30 at a certain position of the drawstring 27, allows limiting the winding and thereby determines the upper position of the winding map 2. The open helical loop 43 at the limiter 28 makes it simple Inserting and removing the drawbar 27 in and out of the guide loop, which must be done when installing and removing the 10 v winding spindles and from the map winder.

Na potezni vrvici 27, nižje pritijena krogla 31 je v položaju navitega zemljevida 2 postavljena v višini za dosego z roko in služi samo za prijem pri potegu.On the drawstring 27, the lower ball 31 is positioned in the coiled map position 2 in height for reaching by hand and serves only for gripping when pulling.

Navijalnik za zemljevide s poteznimi vrvicami 27 je lahko v običajni izvedbi s petimi, na enaki višini in enaki medsebojni oddaljenosti na nosilca navijalnih vreten 8 in 9, nameščenimi navijalnimi vreteni 10 ali v izvedbi s petimi navijalnimi vreteni 10 na spodnji in štirimi na zgornji višini.The map reel retractor 27 can be in the conventional embodiment with five, at the same height and the same distance from each other on the winding spindle brackets 8 and 9, mounted winding spindles 10 or with five winding spindles 10 at the bottom and four at the upper height.

Pri dvovišinski namestitvi navijalnih vreten 10 imamo za obe višini enako rešitev postavitve, konstrukcijsko podobne, vendar na enak način pritrjene nosilce navijalnih vreten 44 in 45 za spodnjo višino in 46 ter 47 za zgornjo višino, kar je prikazano na sl. 9.In the two-height installation of the winding spindles 10, for both heights, we have the same layout solution, similar in structure, but in the same way, the winding spindle supports 44 and 45 are attached to the lower height and 46 and 47 to the upper height, as shown in FIG. 9.

Na drugi višini nameščena navijalna vretena 10 so nekoliko zamaknjena napram spodnji tako, da poteka odvijanje in zavijanje zemljevidov 2, ter potek poteznih vrvic 27, katere so pravtako speljane skozi odprto spiralno zanko 43 omejevalcev 28, nemoteno.The winding spindles 10, which are mounted at the second height, are slightly offset to the lower ones so that maps 2 can be unwound and wrapped, and the course of the pull lines 27, which are also guided through the open spiral loop 43 of the stopers 28, smoothly.
