Description

Housing with a * spring coil and pull-out cord

The invention relates to a housing with a rotatably mounted, spring-tensioned spool and with a cord wound on the spool, the second end of which protrudes from the housing, with a first fastening element on the housing and the opposite end on the projecting second end A second fastening element that can be pulled out of the spring force is provided.

Such a housing can be found, for example, in GB-A-17303/1903 and serves as a holder for a monocle or the like, which is attached to the second fastening element at the end of the cord. The cord can be fixed in various extended lengths by means of a locking device for the spring coil. As the first fastening element, the housing has a hook or a needle, by means of which it can be fastened to the clothing.

Housings are also proposed for attachment to clothing (CH-A-637 278, AT-B-384 937), which are used to hold tickets, in particular ski passes, which have to be inserted into a receiving slot of a control station. The first fastening element consists of a closable bracket which can be attached, for example, to the zipper of the ski suit. Since the housing is a plastic injection molded part, the lockable bracket is formed on one side of the housing, and there is a difficult or unfavorable fastening wherever another fastening element would be advantageous.

Housings, which usually consist of metal and are provided with a suspension bracket 1, also have so-called pocket watches. A chain or a band, the other end of which, for example, is fastened to a piece of clothing with a carabiner, can be attached to the suspension hanger 1. The chain or band thus serves as

REPLACEMENT LEAF Security against loss of watch.

Other embodiments of housings for watches provide connections for a bracelet, have a clip so that the watch can be clamped on, or can be inserted into a ring, a piece of clothing being clamped between the watch housing and the ring.

The invention es- has now the object of the use and Be ^'festi supply poss i th chkei to increase a housing of the type mentioned and to facilitate.

According to the invention, this object is achieved in that a clock with a clockwork, display elements and a watch glass is arranged in the housing, the first fastening element optionally being detachably held on the housing. Such a configuration extends the use of the housing. For example, it can also be used as a pocket watch and can be secured to a piece of clothing by fastening the second fastening element. The watch can be taken out of the pocket and the cord automatically adjusts to the required length. In particular, the line is not an obstacle to the practice of sports due to its spring position. If, on the other hand, the housing is fastened in a known manner by means of the first fastening element, a key, a card or any other objects can be attached to the cord without these having to be detached from the cord during use. If the first fastening element is detachably arranged, various fastening elements can be used optionally, which increases the possible uses. Alternatively, this object is also achieved in that the first fastening element is detachably held on the housing, a clock with a movement, display elements and a watch glass is arranged.

The detachable mounting of the fastening element on the housing allows a fastening element adapted to the fastening possibility to be attached to the housing, for example a closable bracket, an eyelet, a clip, or the like. If the housing contains a clock, the above-mentioned expanded uses are possible.

The housing preferably consists of two interconnected shells. For the clockwork, a recess can be provided in the outside of the first shell and the coil can be rotatably mounted in the second shell. If rings are formed on the second side of the first shell and on the coil side of the second shell, which engage in the form of a corresponding bead / groove connection, then the two housing halves can be joined together and separated again in a simple manner .

It is advantageous if the second shell is cup-shaped and has a radial incision in the area of the spool, through which the cord is guided to the outside. The first and second shells can thus be rotated relative to one another about the coil axis and the display of the clock can be adjusted to the respective viewing direction.

A first embodiment of the housing according to the invention provides that the first, releasably held fastening element is formed by a ring, and that the peripheral wall of the second shell has a cylindrically formed area onto which the ring is interchangeably pushed. In this case, it is advantageous if the ring is provided with a U-shaped hook, the first leg of which is firmly connected to the ring, and the second Leg has a detent at the end, which can be connected in the ring with a corresponding detent element. On the other hand or in addition, the ring can also have two diametrically opposed slots which each extend from the circumferential side to one of the two outer sides of the ring. This allows a band, in particular a bracelet, to be inserted through the slots. A second embodiment of the housing according to the invention provides that the peripheral wall of the second shell has a recess provided with engaging projections and the first, detachably fastened fastening element has a base which is inserted into the recess and the projections reaches behind on at least two sides. Due to the rear-engaging arrangement, the first releasable fastening element can easily be subjected to tension when the spring-loaded cord is pulled out.

The fastener can still in the direction of

Tensile stress can be used or removed when the base part has an elastic catch on at least one side, which detachably engages behind the projection. Each elastic catch is then bent back from its position behind the projection, so that the fastening element can be removed. In a further embodiment, a projection of the recess opposite the projection is designed as a rounded rib which, over a first angular region, forms a pivot bearing for a web of the base part behind the rib. After releasing the catch, the unlocked, first fastening element in this version must be swiveled up by an angle of 15 to 20 before its base part can be removed from the swivel bearing.

Another possibility for exchangeable fixation of the fastening element can be that the base part with the shells open, it can be inserted into the recess of the second shell parallel to the coil axis.

To insert or change the fastening element, the fastening element is pulled out or pushed in perpendicular to the pulling direction with the first shell removed. In this embodiment it is also possible for the base part to engage behind the recess on three sides on the first shell and preferably also on the fourth side on the second shell. A third embodiment of the housing according to the invention provides that the second shell has two diametrically opposite slots, each of which extends from the peripheral wall to the outside of the second shell, and the first, detachably fastener by a through the slots drawn ribbon, especially a bracelet made by Idet.

In a further embodiment of the housing according to the invention it is provided that the two shells can be rotated relative to one another about the coil axis.

At the protruding second end of the cord, an eyelet or the like is advantageously fastened, on which an elastically spreadable fastening ring can be provided as the second fastening element. A fastening ring, which can be provided in particular on a housing according to the invention as the first and / or second fastening element, is advantageously made in one piece from plastic and is provided at its two ends with latch elements which can be connected to one another. Such a fastening ring could also be used in another way, for example as a key ring or the like.

In a first embodiment of the fastening ring, preferably provided that the first end has a flattening running parallel to the ring plane, from which a locking pin protrudes perpendicularly, and that the second end has a groove corresponding to the flattened first end, in the bottom of which an opening is provided for receiving the locking pin.

In a second embodiment, the first end can have two flats running parallel to the ring plane and a nose directed away from the end can be formed on the outer circumference, the second end then having an incision running parallel to the ring plane, in which an undercut fertilizer Bridge is provided. When the fastening ring is closed, the first end with its flats is inserted into the incision in the second end and the nose is locked in the undercut. Such mounting rings are relatively easy to manufacture and easy and safe to close. A corrugation or corrugation formed on the circumference of the fastening ring facilitates opening and closing.

For the stability of the fastening ring, it is advantageous if the second end is made thickened. If the thickening has a central taper, then a securing element can be pushed on and secured against unintentional separation of the two ends. The securing element can be formed, for example, by the connector provided at the projecting end of the cord.

The invention will now be described in more detail below with reference to the figures of the accompanying drawings, without being limited thereto. Show it :

17 and 18 sections according to FIG. 15 through variants of the first fastening element receiving part of the housing.

As can be seen in more detail from FIGS. 1 to 3 or 14, 15, a housing 1 is approximately can-shaped and is composed of a first shell 3, which represents an upper part or cover, and a second shell 2, which is a lower part or basic body, together. On the one hand, the housing 1 provides a holder for tickets, ID cards or the like 45 (Fig. 15), which are attached to a second fastening element 7 and / or a holder for a clock 4, which is placed in an outer recess of the first shell 3. The two shells 2, 3 are connected to one another via a snap connection 18 formed by an annular groove and an annular bead, so that they are easily assembled, rotated relative to one another about the axis 15, and can also be separated again. In addition, a connecting screw 14 (FIG. 3) can be provided. The outside recess of the first shell 3 receives a clockwork 16, a dial and a watch glass 17, which is kept fertilized in a Hi nterschnei. The adjusting shaft of the clockwork 16 is led out through a side channel and screwed to the crown, the watch glass and the crown being sealed by sealing rings. For the sake of clarity, however, these details relating to the clock are no longer shown in the drawings.

Inside the second shell 2, a coil 5 is rotatably mounted about the axis 15 and is biased by a spiral spring. A cord 6 is wound on the spool 5, the first end of which is firmly connected to the spool 5, and the second end of which is led outwards through a radial incision in the second shell 2 and is connected to a second fastening element 7. The cord 6 can now be pulled out of the housing 1 against the spring force by pulling on the second fastening element 7 and automatically retracts into the housing 1 when the force decreases. As can be seen from FIGS. 1 and 2, the end of the cord 6 is fastened to an eyelet 11 or the like, in which the second fastening element 7 is suspended. For the partial reception of the eyelet 11, the peripheral wall 8 of the second shell 2 is provided with a recess or recess 19. As shown in FIGS. 14 and 15, the second fastening element 7 can also be fastened directly to the cord 6, the second fastening element 7 engaging in the recess 19.

If, for example, the second fastening element 7 is now connected to a garment of the wearer, the housing 1 can be pulled away as desired when reading the time and is then automatically returned again. The dial can be adjusted by rotating the first shell 3 relative to the second shell 2 according to the respective viewing angle.

In the peripheral wall 8 of the second shell 2, a recess 9 is provided diametrically to the recess 19, which is divided by a web 13 of the peripheral wall 8. A first fastening element 10 is detachably inserted into this recess 9, which is formed, for example, by the fastening ring 30, which will be explained in more detail later, and can be exchanged for other fastening elements adapted to the respective intended use. With the help of the first fastening element 10, the housing 1 can now be hung on a piece of clothing. The cord 6, which can be pulled out against the spring force, can thus be used for other purposes. For example, a key, a ticket 45 or other frequently used objects can be attached to the cord 6, which are therefore easy to handle and are held captive on the outside of the body.

2 to 4 furthermore show diametrically opposite slots 12 in the second shell 2, which extend between the peripheral wall 8 and the circumferential area of the outside of the shell 2. A first fastening element 20, which is shown schematically in FIG. 3 and 4 by an arrow, can be fastened to the slots 12, for example be hooked in, plugged in, etc. 4 is a band 21, for example an arm band, which is pulled through slots 12.

With the aid of the connecting screw 14, a first fastening element 20 could also be provided interchangeably on the housing 1 or on the second shell 2.

5 and 6 show a further embodiment of a first fastening element 10 which is in the form of a ring 25. A cylindrical region is formed on the peripheral wall 8 of the second shell 2, over which the ring 25 can be pushed, which is secured by a bead 24. The first leg of a U-shaped fastening hook 26 is formed on the ring 25. The second leg of the fastening hook 26 is elastically spread out and has a hook-shaped catch 27 at its end. A radial incision is provided in the ring 25, in which a catch element 28 corresponding to the catch 27 is arranged. Thus, the fastening hook 26 can be easily opened and securely closed. If the fastening element 10 is to be exchanged, the ring 25 can be pulled off and replaced by another which, for example, instead of a hook 26 carries a clip or another fastening element, a base or the like. A preferred variant of such a ring is shown in FIGS. 7 and 8. This ring 25 has two slots 29 running radially and parallel in the ring plane, so that, similar to the embodiment according to FIGS. 2 to 4, a bracelet can be threaded. A housing 1 provided with the clock 4 can thus be used as a normal wristwatch. This ring 25 is provided with two pins 23 which engage in holes in the second shell 2 and prevent rotation of the ring 25 on the second shell. 9 to 13 show two versions of the fastening ring 30 used as the first and / or second fastening element 7, 10 in FIGS. 1 to 4, which surrounds the web 13 or is inserted into the eyelet 11. The fastening ring 30 consists in particular of plastic and is divided so that it has two ends 31, 32. In the embodiment according to FIGS. 9 to 11, the first end 31 is provided with a flat 33, from which a locking pin 34 protrudes perpendicular to the ring plane. The second end 32 is thickened and provided with a groove 35, the depth of which corresponds to the thickness of the flattened first end 31. Corresponding to the locking pin 34, the second end 32 has an opening 36 in the bottom of the groove 35, into which the locking pin 34 can be inserted. The opening 36, which is preferably designed as a bore, is widened on the outside, so that an end bead (not designated) of the locking pin 34 can latch

12 and 13 show the second embodiment of the fastening ring 30. The ends 31 and 32 of this fastening ring 30 are elastically spread apart and likewise have latching elements which can be connected to one another. At the first end 31, flats 33 are provided on both sides parallel to the ring plane. Furthermore, there is a recess on the outer circumference, through which a nose 37 directed away from the first end 31 is formed. The second end 32 has a thickened region 41, in which an incision 38 running in the ring plane is provided for receiving the first end 31, which is provided with an undercut fertilizer 39 (FIG. 13). By squeezing the ring 4, the first end 31 can be inserted with its flats 33 into the incision 38 and locked with its nose 37 in the Hi nterschnei fertilizer 39. The thickened area 41 has a central taper 42, over which a securing element is pushed can. When using the fastening ring 30 as the second fastening element 7, the securing element can be passed through the eyelet 11 be formed so that unintentional opening is prevented by compressing the fastening ring 30. The fastening ring 30 is easy to manufacture and has no moving parts and joints. A welLung 40 on the outer circumference facilitates handling when opening and closing. The fastening ring 30 can therefore also be used in another way, for example as a key ring etc.

In the embodiment of the housing 1 according to FIGS. 14 to 18, a clasp is provided as the second fastening element 7, which, as mentioned, is fixed directly to the cord 6. As shown in FIG. 15, the clasp has a snap fastener which, for example, penetrates a ticket 45. With the cord 6 wound, the second fastening element 7 lies positively in the recess 19 of the peripheral wall 8 of the second shell 2 to stabilize the position.

The connection with a piece of clothing or another object takes place again via the first fastening element 10 provided diametrically to the second fastening element 7, which in this embodiment consists of a base part 47 and a connecting part 52. The base part 47 is inserted into the recess 9 in the peripheral wall 8 and engages behind on one side with an e lasti see catch 50 a projection 48 of the peripheral wall 8 and on the opposite side with a web 51 a projection 49 designed as a rounded rib of the peripheral wall 8. the catch 50 st in the direction towards the base part 47 from the Hintergπ ^'ffsbereich the recess 9 Σurückziehbar, so that the base portion 47 is unlocked at this point. The rounded rib of the projection 49 on the opposite side of the projection 48 forms a visual pivot bearing, so that the base part 47 can be pivoted upwards after unlocking the catch 50 until the web 51 can be pulled out from under the rib. This fastening element 10 is therefore also simple interchangeable, with several fastening elements with different types of connecting elements being available. Three preferred configurations are shown in the figures. 14 to 16 show a fastening element 10, the connecting part l of which, like FIG. 6, is formed by a hook 52 which is integrally formed on the base part 47 and can be locked on the other side on the base part 47. Such a hook can be used, for example, for fixation to the eye of a tear-released loosse. FIG. 17 shows an embodiment in which the connecting part 1 is designed as an eyelet 53. Such an embodiment is used for threading on a cord that can be worn around the neck, for example. 18 shows an embodiment with an attachment bracket 54 as a connecting part, the clamping leg of which extends parallel to the outside of the second shell 2 of the housing 1. For a non-clamping fixation on an object, the outside of the clamping leg can also be provided with a self-adhesive coating in this embodiment.

In this embodiment, the first shell 3 of the housing 1 is provided on the inside with a central opening which, after the clockwork 16 has been inserted, as shown in FIG. 15, can be covered by a clipped-on closure flap 46. In this embodiment, the clockwork 16 projects into the interior of the coil 5.
