1.0 Fi~ld of the Inven~ion:
This invention relates senerally to ~and-held film transfer devices, and more particularly to hand-held devices for transferring a film from a backing tape to a substrate.
2.0 Discussion of Related Art:
In typical hand-held devices for film transfer, a supply reel and a take-up reel are arranged adjacent one another in one plane in the same way as in an audio cassette. A backing tape coated on one side with an adhesive film is wound onto the supply reel while the take-up reel is intended to take up the used backing tape. The coated backing tape is guided from the supply reel over an application element which is placed on the substrate to which the adhesive is to be applied. By relative movement between the hand-held device and the substrate, the adhesive is transferred from the backing tape to the substrate and, at the same time, the adhesiveless backing tape is wound up by the take-up reel.
One known hand-held device ~German DE-PS 37 36 357) is essentially formed by three different functional elements. A

A closed changing cassette is designed to be fixedly loaded into this intermediate housing by centering means. The supply reel and the take-up reel are mounted for rotation in this cassette and the application element is part of the cassette. In aidition, a rewind lock in the form of a spring lip provided in a side wall of the cassette is integrated into the cassette, and engages i. a gear rim additionally formed on the take-up reel. A third functional element, in the form of a substantially closed housing case with a locking clip, is designed to pivot over the changing cassette loaded into the intermediate housing and over the intermediate housing. Only the application element with the backing tape projects from the housing case in the closed position. To reload the hand-held device, first the housing case is opened, followed by removing the changing cassette from the intermediate housing.
A new cassette is installed and the intermediate housing case is closed again.
Although the operation of this known hand-held device is relatively simple and error-free, it is very complicated in its construction, making the device relatively expensive.

3.0 Summ~y of the I_Je tion~
lC An o~ect of the present invention is to provide a simplified hand-held film transfer device that has high serviceability, ease of handling, and relatively low cost.
In one embodiment of the invention, these and other objects of the invention are provided by a hand-held film 1, transfer device including the carrier ele~ent in the form of a carrier plate designed to be fixed between two housing halves which fit together, with holders for the supply reel and the take-up reel. The carrier plate has a substantially triangular region with an integral application element covering approximately half the supply reel and a web-like region bearing the take-up reel.

Through this design, which fully retains serviceability and ease of handling, the hand-held device is simplified to such an extent that production costs are considerably reduced ", ,.~ . . .

relative to pr.or such devices. The present hand-held device includes two housing halves, which fit together, and a carrier plate designed to be inserted between the housing halves, so that a consi~erable saving of material is possible compared with the known hand-held device. The carrier plate is essentially used solely tc keep the take-up reel and the supply reel in the cor~ect position to one another before they are lcaded into the housing, so that the operator does not come into contact with the -~ilm to be transferred. After insertion into the housing, the carrier plate has no other functions to perform because the supply reel and the take-up reel are mounted in both housing halves so that the carrier plate performs no mounting or bearing functions. In addition, the carrier plate is particularly simple, and saves material through formation of the rewind lock on a wall of the housing rather than in the carrier plate, so that the carrier plate need only comprise a narrow fixing flange in the region of the take-up reel.
In one particularly simple embodiment of the invention, the application element is formed by two triangularly tapering transverse walls of the carrier plate. Bowever, other arrange-ments are also possible; for example, an application roller around which the backing tape is guided may be additionally arranged on the carrier plate.
In one particularly preferred embodiment of the invention, the gear tooth system is integrated into the rotation pin, and the slipping clutch is part of the gear tooth ~'''' ' ' '~ ' . ,' ~, ~:; , ~08~22 system. ~his arrangement reduces the number of component parts, and ~implifies production so that production costs are further reduced. ~he hand-held device comprises two rotation pins each with an integral gear tooth system, one for the 5 supply reel and the other for the take-up reel.
One particularly advant~?eous embodiment of the invention includes the teet~ of the rotation pin for the supply reel formed with lamellar necks in the region bet-~een the tooth rim and the tooth flanks, and in the region of the tooth flanks, lG the teeth of both rotation pins being beveled in the plane perpendicular to the tooth flanks in such a way that, in the event of a difference in speed, the teeth of the rotation pin for the s~pply reel are designed to slip over the teeth of the rotation pin for the taXe-up reel.
lS This design of the slipping clutch is particularly simple. The slipping clutch does not consist of a separate element, but is an integral part of the gear tooth system. The beveled teeth of the supply reel, which are made resilient by the lamellar design of their necks, can slip over the correspondingly beveled teeth of the rotation pin for the take-up reel. The response of the slipping clutch can be controlled through the resilience of the teeth of the rotation pin for the supply reel. The resilience level can be influenced by the design of the lamellar tooth necks, and the length and thickness of the tooth necks. The lamellar form of the teeth can be varied to meet various design requirements.
In conjunction with the design of the slipping clutch, .....
another embodiment of the invention is characterized in that, beneath the beveled teeth of the rotation pin for the supply reel, the rewind lock is in the form of a correspondingly beveled housing element of the housing half facing the gear 5 -ooth system, so that the teeth of the rotation pin can only slip over the housing element in the direction of rotation.
.~ccordingly, there is no need for any additional means to Drovide the rewind lock for preventing incorrect operation of the device, instead it is merely necessary to provide a ~eveled, tooth-like housing element over which the resilient teeth slip in the direction of rotation, but are blocked in the opposite direction.

A hand-held device 1, for transferring a film from a backing tape 2 to a substrate (not shown in detail), comprises a housing 3 formed by two housing halves, namely an upper housing half 3a and a lower housing half 3b (see Figures 1 and 2). The two housing halves 3a and 3b are joined firmly to one another by a U-shaped clip closure 4 with gripping surfaces 5.
At the ends of its sides, the U-shaped clip closure 4 comprises two detents 6, 7 arranged one above the other (see Fig. 3).
The detents 6 each engage for longitudinal displacement in grooves 8, which are formed by the upper housing half 3a and , -` 2008822 the lower housing half 3b, and which extend over the entire length of the housing 3. The clip closure 4 surrounds the upper housing half 3a with its detents 6 in such a way that, even when the lower housing half 3b is removed, it is connected for long-tudinal displacement to the upper housing half 3a. A
second groove 9 is formed for each detent 7 in the lower housing half 3b, extending only over a limited ranqe.
The grooves 9 are each separated from the associated groove 8 by a web 10. The web 10 only extends over the range shown in Figure 2, whereby the detents 7 of the clip closure 4 dG not engage in the grooves 9 in the position shown in Figure 2, i.e. the housing halves 3a and 3b are not joined to one another. By displacement of the clip closure 4, the detents 7 engage in the grooves 9, so that the two housing halves 3a, 3b are joined firmly to one another. A constriction 11 is provided in each groove 9 for firmly locking the clip closure 4 in the grooves 9.
In addition, t~e upper housing half 3a is formed with an opening 12 through which the filling level of a supply reel-described in more detail hereinafter - for the backing tape 2 can be checked. The housing halves 3a and 3b comprise a plate-like, triangular end 13a, 13b for an application element 14 for the backing tape 2.
As shown particularly clearly in Figure 4, a carrier plate 15 is designed to be introduced into the housing 3. The carrier plate 15 comprises a substantially triangular region 16 (see Figure 5) and a web-like region 17. The application _,. - -~ , ,, ' '.,, ' ' ,, ' ~ ' ~' . ' - , .- ~ ', ,' ' '... ' ' ~,,, . .,, . , ' :
element 14 is designed as part of the triangular region 16, for which purpose triangularly tapering transverse walls 18 are formed on the carrier plate 15. Formed in the triangular region 16 of the carrier plate 15 is a holder 19 for a supply reel 20, the holder 19 being formed by an opening 21 and a detent hook ~2 for the supply reel 20 (see Figure 6). The supply reel 2C lS arranged for rotation on the carrier plate 15 by simple engagement in the detent hook 22. The carrier plate 15 correspondingly comprises a holder 23 - formed by an opening 25 and a detent hook 26 -for a take-up roller 24 at the end of the web-like region 17. The take-up roller 24 is arranged for rotation on the carrier plate 15 by engagement in the detent hook 26.
Formed in the lower housing half 3b are two journal pins 27, 27a for a rotation pin 28 for the supply reel 20 and for a rotation pin 29 for the take-up reel 24, the journal pin 27 being formed at its free end with a detent for axially fixing the rotation pin 28. A gear tooth system 30, 31, of which the particular design will be described in detail hereinafter, is integrated into each rotation pin 28, 29.
: .
The upper housing half 3a also comprises journal pins 32, 33 which, in the assembled state of the hand-held device 1, are correspondingly opposite the journal pins 27, 27a in the lower housing half 3b, and are designed in such a way that they project through the openings 21 and 25, of the holders 19, 23 of the carrier plate 15, into the supply reel 20 and the take-up reel 24, for which they serve as bearings.

~, ' , ~ ,' ', ' '. ' ' ; .' ' ,, ' '' ' " " , ,' `-- 2008822 Accordingly, after introduction into the housing 3, the supply reel 20 and the take-up reel 2~ are only mounted in the housing halves 3a and 3b and not in the carrier plate 15, i.e.
the sole Iunction of the carrier plate 15 is to hold the supply reel 2C and the take-up reel 24 in the correct position to one another befor~ they are introduced into the housing 3. When the carrie- plate 15 is inserted into the housing 3, the supply reel 20 fits onto the rotation pin 28 and the take-up reel 24 onto the rotation pin 29, a fixed connection between the particular reel and the corresponding rotation pin being established by a known splined shaft coupling or the like. By fitting on the upper housing half 3a and closing the housing by means of the clip closure 4, the supply reel 20 and the take-up reel 24 2re correspondingly aligned in the housing by means of the journal pins 32 and 33.
Figures 5 to , show only the carrier plate 15 with the supply reel 20 and the take-up reel 24. The backing tape is not shown in detail. However, it is guided from the supply reel 20 around the application element 14 into the take-up reel 24. As shown in Figure 7, the supply reel 20 and the take-up reel 24 are joined to the carrier plate solely via the simple detent hooks 22 and 26.
Figures 8 and 9 respectively show only the lower housing half 3b with the carrier plate 15 introduced, and without the carrier plate, respectively. The drive connection between the rotation pins 28 and 29 can be seen in Figure 9, being formed by gear tooth systems 30, 31 integral with the particular ,,: ~ ,. .... . . .
~' '' ' :''' '' - , ',' -rotation pin; only a few teeth 34, 35 of the gear tooth systems 30, 31 are shown.
The particular configuration of the gear tooth systems is shown in Figures 10 to 13. The gear tooth systems 30, 31 of the rotation pins 28, 29 ar~ designed in such a way that they ~ ~-serve simultaneously as a slipping clutch. To this end, the teeth 34, 35 are specially shaped, as shown in Figure 12. In the overlap region, the teeth 34, 35 of the gear tooth systems 30,31 are each beveled with the same pitch in the plane perpendicular to the tooth flanks in such a way that the oblique surfaces 37, 38 come into contact in the direction of rotation (arrow 36 in Figure 10), the oblique surfaces 37 of the teeth 34 slipping over the oblique surfaces 38 of the gear tooth system 31 in the event of a difference in speed between the two gear tooth systems.
This slipping effect is made possible by a flexible construction of the teeth 34 of the gear tooth system 30. To this end, the teeth 34, which are preferably made of plastic, are lamellar in design in the region of their neck 39 between the gear rim 40 and the tooth flanks 41 (see Figure 11), the removal of material being denoted by the reference 42. By means of these resilient lamellar necks 39, the teeth 34 are able to slip along their oblique surfaces 37 on the oblique surfaces 38 of the teeth 35, i.e. a slipping clutch directly integrated into the gear tooth system is formed in a particularly simple manner without any additional elements.
In Figures 10 and 13, a special rewind lock is also 11 - .
formed through this special design of the teeth 34 of the gear tooth syste~ 30. Formed to this end beneath the beveled teeth 34 is a correspondingly beveled housing element 43 with an oblique surface 44 which is part of the lower housing half 3b.
In the direction of rotation, the teeth 34 of the gear tooth system 30, by virtue of their resilience, are able to slip with their oblioue surfaces 37 over the oblique surface 44 of the housing element 43. By contrast, the teeth 34 are prevented from t~rning in the opposite direction by the housing element 43.
By virtue of this configuration, the slipping clutch is directly int~grated into the gear tooth system in a par-ticularly sir!ple manner, and the rewind lock is also a part of the drive connection arra~ged in the housing, so that the carrier plate 15 merely comprises the application element 13, and is solely used to carry the supply reel 20 and the take-up reel 24 before they are introduced into the housing 3, i.e. the carrier plate 15 performs no other functions and is therefore particularly simple and inexpensive to make.
The invention is not confined to the examples of embodiments shown in the drawings. Other embodiments of the invention are possible without departing from the basic illustrated concepts or from the spirit and scope of the appended claims. For example, the application element may be differently designed, etc.

A hand-held device 1, for transferring a film from a backing tape 2 to a substrate (not shown in detail), comprises a housing 3 formed by two housing halves, namely an upper housing half 3a and a lower housing half 3b (see Figures 1 and 2). The two housing halves 3a and 3b are joined firmly to one another by a U-shaped clip closure 4 with gripping surfaces 5.
At the ends of its sides, the U-shaped clip closure 4 comprises two detents 6, 7 arranged one above the other (see Fig. 3).
The detents 6 each engage for longitudinal displacement in grooves 8, which are formed by the upper housing half 3a and , -` 2008822 the lower housing half 3b, and which extend over the entire length of the housing 3. The clip closure 4 surrounds the upper housing half 3a with its detents 6 in such a way that, even when the lower housing half 3b is removed, it is connected for long-tudinal displacement to the upper housing half 3a. A
second groove 9 is formed for each detent 7 in the lower housing half 3b, extending only over a limited ranqe.
The grooves 9 are each separated from the associated groove 8 by a web 10. The web 10 only extends over the range shown in Figure 2, whereby the detents 7 of the clip closure 4 dG not engage in the grooves 9 in the position shown in Figure 2, i.e. the housing halves 3a and 3b are not joined to one another. By displacement of the clip closure 4, the detents 7 engage in the grooves 9, so that the two housing halves 3a, 3b are joined firmly to one another. A constriction 11 is provided in each groove 9 for firmly locking the clip closure 4 in the grooves 9.
In addition, t~e upper housing half 3a is formed with an opening 12 through which the filling level of a supply reel-described in more detail hereinafter - for the backing tape 2 can be checked. The housing halves 3a and 3b comprise a plate-like, triangular end 13a, 13b for an application element 14 for the backing tape 2.
As shown particularly clearly in Figure 4, a carrier plate 15 is designed to be introduced into the housing 3. The carrier plate 15 comprises a substantially triangular region 16 (see Figure 5) and a web-like region 17. The application _,. - -~ , ,, ' '.,, ' ' ,, ' ~ ' ~' . ' - , .- ~ ', ,' ' '... ' ' ~,,, . .,, . , ' :
element 14 is designed as part of the triangular region 16, for which purpose triangularly tapering transverse walls 18 are formed on the carrier plate 15. Formed in the triangular region 16 of the carrier plate 15 is a holder 19 for a supply reel 20, the holder 19 being formed by an opening 21 and a detent hook ~2 for the supply reel 20 (see Figure 6). The supply reel 2C lS arranged for rotation on the carrier plate 15 by simple engagement in the detent hook 22. The carrier plate 15 correspondingly comprises a holder 23 - formed by an opening 25 and a detent hook 26 -for a take-up roller 24 at the end of the web-like region 17. The take-up roller 24 is arranged for rotation on the carrier plate 15 by engagement in the detent hook 26.
Formed in the lower housing half 3b are two journal pins 27, 27a for a rotation pin 28 for the supply reel 20 and for a rotation pin 29 for the take-up reel 24, the journal pin 27 being formed at its free end with a detent for axially fixing the rotation pin 28. A gear tooth system 30, 31, of which the particular design will be described in detail hereinafter, is integrated into each rotation pin 28, 29.
: .
The upper housing half 3a also comprises journal pins 32, 33 which, in the assembled state of the hand-held device 1, are correspondingly opposite the journal pins 27, 27a in the lower housing half 3b, and are designed in such a way that they project through the openings 21 and 25, of the holders 19, 23 of the carrier plate 15, into the supply reel 20 and the take-up reel 24, for which they serve as bearings.

~, ' , ~ ,' ', ' '. ' ' ; .' ' ,, ' '' ' " " , ,' `-- 2008822 Accordingly, after introduction into the housing 3, the supply reel 20 and the take-up reel 2~ are only mounted in the housing halves 3a and 3b and not in the carrier plate 15, i.e.
the sole Iunction of the carrier plate 15 is to hold the supply reel 2C and the take-up reel 24 in the correct position to one another befor~ they are introduced into the housing 3. When the carrie- plate 15 is inserted into the housing 3, the supply reel 20 fits onto the rotation pin 28 and the take-up reel 24 onto the rotation pin 29, a fixed connection between the particular reel and the corresponding rotation pin being established by a known splined shaft coupling or the like. By fitting on the upper housing half 3a and closing the housing by means of the clip closure 4, the supply reel 20 and the take-up reel 24 2re correspondingly aligned in the housing by means of the journal pins 32 and 33.
Figures 5 to , show only the carrier plate 15 with the supply reel 20 and the take-up reel 24. The backing tape is not shown in detail. However, it is guided from the supply reel 20 around the application element 14 into the take-up reel 24. As shown in Figure 7, the supply reel 20 and the take-up reel 24 are joined to the carrier plate solely via the simple detent hooks 22 and 26.
Figures 8 and 9 respectively show only the lower housing half 3b with the carrier plate 15 introduced, and without the carrier plate, respectively. The drive connection between the rotation pins 28 and 29 can be seen in Figure 9, being formed by gear tooth systems 30, 31 integral with the particular ,,: ~ ,. .... . . .
~' '' ' :''' '' - , ',' -rotation pin; only a few teeth 34, 35 of the gear tooth systems 30, 31 are shown.
The particular configuration of the gear tooth systems is shown in Figures 10 to 13. The gear tooth systems 30, 31 of the rotation pins 28, 29 ar~ designed in such a way that they ~ ~-serve simultaneously as a slipping clutch. To this end, the teeth 34, 35 are specially shaped, as shown in Figure 12. In the overlap region, the teeth 34, 35 of the gear tooth systems 30,31 are each beveled with the same pitch in the plane perpendicular to the tooth flanks in such a way that the oblique surfaces 37, 38 come into contact in the direction of rotation (arrow 36 in Figure 10), the oblique surfaces 37 of the teeth 34 slipping over the oblique surfaces 38 of the gear tooth system 31 in the event of a difference in speed between the two gear tooth systems.
This slipping effect is made possible by a flexible construction of the teeth 34 of the gear tooth system 30. To this end, the teeth 34, which are preferably made of plastic, are lamellar in design in the region of their neck 39 between the gear rim 40 and the tooth flanks 41 (see Figure 11), the removal of material being denoted by the reference 42. By means of these resilient lamellar necks 39, the teeth 34 are able to slip along their oblique surfaces 37 on the oblique surfaces 38 of the teeth 35, i.e. a slipping clutch directly integrated into the gear tooth system is formed in a particularly simple manner without any additional elements.
In Figures 10 and 13, a special rewind lock is also 11 - .
formed through this special design of the teeth 34 of the gear tooth syste~ 30. Formed to this end beneath the beveled teeth 34 is a correspondingly beveled housing element 43 with an oblique surface 44 which is part of the lower housing half 3b.
In the direction of rotation, the teeth 34 of the gear tooth system 30, by virtue of their resilience, are able to slip with their oblioue surfaces 37 over the oblique surface 44 of the housing element 43. By contrast, the teeth 34 are prevented from t~rning in the opposite direction by the housing element 43.
By virtue of this configuration, the slipping clutch is directly int~grated into the gear tooth system in a par-ticularly sir!ple manner, and the rewind lock is also a part of the drive connection arra~ged in the housing, so that the carrier plate 15 merely comprises the application element 13, and is solely used to carry the supply reel 20 and the take-up reel 24 before they are introduced into the housing 3, i.e. the carrier plate 15 performs no other functions and is therefore particularly simple and inexpensive to make.
The invention is not confined to the examples of embodiments shown in the drawings. Other embodiments of the invention are possible without departing from the basic illustrated concepts or from the spirit and scope of the appended claims. For example, the application element may be differently designed, etc.
