BACKGROUND
Printers have an output where a printed product leaves the printer. Typically, the printed product is a sheet material of a given material and size. A printed product collecting assembly is to collect the printed product from the output of the printer. Among others the printed product is collected on a flat surface or it can be collected in a bag formed by a fabric material. The printed product can be a single sheet, or multiple sheets can be collected in a stack.

DETAILED DESCRIPTION
FIG. 1 illustrates a printer 18 which has a printed product collecting assembly 10 according to one example. The convertible printed product collecting assembly 10 includes a collecting fabric 11 which has a longitudinal and a transversal direction.
As illustrated in detail in FIGS. 5a, 5b, the collecting fabric 11 is fixed at one end, in its longitudinal direction, to and rolled on a rotatable fabric bearing rod 19 which extends in the transversal direction of the fabric. In the example of FIGS. 5a, 5b the fabric bearing rod 19 is coupled to a tensioning and locking mechanism 15,16 which is operable to tension the collecting fabric 11 and to hold the collecting fabric 11 in a flat, tensioned shape, as wilt be described later.
Returning to the example of FIG. 1, the collecting fabric 11 is fixed at its other end to a transversal fixation rod 17. The collecting fabric 11 is to receive the printed product from a printer output. The printed product from the printer may be, e.g., a sheet material of a given material and size Generally spoken, the printed product collecting assembly 10 is to collect the printed product from the output of the printer, wherein, among others, the printed product can be collected on a flat surface formed by the collecting fabric 11, or it can be collected in a bag which is also formed by the fabric 11. The printed product can be for example, a single sheet, or multiple sheets that may be collected in a stack.
In an example, as illustrated in FIG. 1, the printed product collecting assembly 10 has supporting legs 13 which are connected to the printer 18. in particular to a printer supporting base 12, and which are tiltable in the collecting fabric's longitudinal direction. In an example, the supporting legs 13 have hinge members 13c located on at least one of its ends, e.g., at the lower end to be mounted at the printer supporting base 12, so that the supporting legs 13 are tiltable relative to the hinge members 13c in the collecting fabric's 11 longitudinal direction. In the example of FIGS. 11A, the printer supporting base 12 has a transverse foot member 12a which is mounted on swivel castors 12b.
Further, in an example and as illustrated in FIGS. 1, 1A, the supporting legs 13 are telescopic legs which include first and second telescopic parts 13a, 13b, the supporting legs 13 being tiltable in the collecting fabric's longitudinal direction. The lower end of the first telescopic part 13a is connected to the hinge member 13c. In the example of FIG. 1, the upper end of second telescopic part 13b is connected to support the transversal fixation rod 17. On the other hand, in the example of FIG. 1A, the upper end of second telescopic part 13b is connected the fabric bearing rod 19 with an associated tensioning and locking mechanism 16.
Stabilizing brackets 14 are coupled to the supporting legs 13. In an example, as illustrated in FIGS. 1, 1A, 2, the stabilizing brackets 14 are stabilizer arms which are at one end connected to the supporting leg 13 and which are at the other end connected to the printer supporting base 12, wherein the stabilizer arms 14 are connected by a hinge element 14a to the supporting legs 13.
In an example, the stabilizing arms 14 are slidingly attached In a longitudinal direction of the supporting legs 13. In an example, the stabilizing arms 14 are slidingly attached in a longitudinal direction of an elongate rail 14c extending on the printer supporting base 12. In another example, the stabilizing arms 14 are slidingly attached in both: the longitudinal direction of the supporting legs 13; and the longitudinal direction of an elongate rail 14c extending on the printer supporting base 12. In an example, the stabilizer arms 14 are connected by another hinge element 14b to the printer supporting base 12 or to the elongate rail 14c extending on the printer supporting base 12. so as to accommodate tilting movement of the supporting legs 13 relative to the printer supporting base 12.
The tensioning and locking mechanism 15, 16 of FIG. 1 is associated to the fabric bearing rod 19 to rotate the fabric bearing rod 19, thereby releasing the fabric bearing rod 19 to rotate in a releasing state and to lock the fabric bearing rod 19 against rotation in a locking state. In a similar way, the tensioning and locking mechanism 16 of FIG. 1A, which has not the tube 15 in me example shown in FIG. 1A, is associated to the fabric bearing rod 19 to rotate the same releasing the fabric bearing rod 19 to rotate in a releasing state and to lock the fabric bearing rod 19 against rotation in a locking state.
In general, one of the fabric bearing rod 19 with its associated tensioning and locking mechanism 15, 16 (FIG. 1) or 15 (FIG. 1A) and the transversal fixation rod 17 is connected to and supported by upper ends of the supporting legs 13, and the other is to be arranged close to the printer 18 output.
In an example, as illustrated in FIGS. 1 and 2, the fabric bearing rod 19 with its associated tensioning and locking mechanism 15, 16 is arranged close to the printer 18 output, and the transversal fixation rod 17 is connected to and supported by upper ends of the supporting legs 13.
In another example, as illustrated in FIG. 1A, the fabric bearing rod 19 with its associated tensioning and locking mechanism 16 is connected to and supported by upper ends of the supporting legs 13, and the transversal fixation rod 17 is arranged close to the printer 18 output.
In an example, as illustrated in FIGS. 1 and 2, the tensioning and locking mechanism 15, 16 includes a tube 15, in which the fabric bearing rod 19 is rotatably mounted, and wherein the tube 15 has an elongate slot or opening 15a, extending in the fabric's 11 transversal direction, through which the fabric 11 exits the tube 15.
In an example, the tensioning and locking mechanism 15, 16 includes a tube 15 in which the fabric bearing rod 19 is rotatably mounted. In an example as shown in FIG. 1 the tensioning and locking mechanism 15, 16 is operative in that it optionally releases or locks rotation between an end of the tube 15 and the fabric bearing rod 19.
In an example, as illustrated in FIGS. 4, 5a, 5b, the tensioning and locking mechanism 15, 16 includes a toothed wheel 16a connected to an end of the fabric bearing rod 19, and one or more arcuate leaf springs 16b connected to the tube 15 by fastening elements which are schematically illustrated at 16c.
In the illustrated example, the toothed wheel 16a and the at least one leaf spring 16b are displaceable relative to each other in the longitudinal direction of the fabric bearing rod 19 so that in a first relative position the toothed wheel 16a and the at least one leaf spring 16b are engaging each other in a locking state to lock the fabric bearing rod 19 against rotation in a sense of rotation in which the fabric 11 would become slack, i.e. the toothed wheel 16a and the at least one leaf spring 16b cooperate in a ratchet type manner. In a second relative position the toothed wheel 16a and the at least one leaf spring 16b are disengaged from each other in a releasing state to release the fabric bearing rod 19 to rotate in any direction.
In an example, the toothed wheel 16a is connected to an actuating knob 16d protruding from one end of the tube 15. The toothed wheel 16a is displaceable relative the at least one leaf spring 16b between said first and second relative positions by moving the actuating knob 16d in the longitudinal direction of the fabric bearing rod 19. Additionally, in an example, a spring 19c may be accommodated in an interior cavity 19b in the fabric bearing rod 19. which spring 19c is to bias the rotation of the rod 19 in one direction.
In an example, one actuating knob 16d is provided on each end of the fabric bearing rod 19. the actuating knobs 16d both being coupled to the toothed wheel 16a so that the latter is displaceable in the longitudinal direction of the fabric bearing rod 19 by each of the actuating knobs 16d.
The tensioning and locking mechanism 15, 16 is operable to tension the collecting fabric 11 and to hold the same in a flat, tensioned shape when the tensioning and locking mechanism 15, 16 is in the locking state, as illustrated by FIGS. 1 and 1A.
On the other hand, the tensioning and locking mechanism 15. 16 is operable to release and unreel the collecting fabric 11 from the fabric bearing rod 19 to form a collecting bag, as shown in FIG. 2 for the example of FIG. 1. After forming the collecting bag the tensioning and locking mechanism 15, 16 might be brought into the locking state to prevent further unreeling of the fabric 11 from the fabric bearing rod 19, or, if the fabric 11 is completely unreeled from the fabric bearing rod 19, to which the fabric's longitudinal end is fixed, the tensioning and locking mechanism 16 may remain in the releasing state.
In the example of FIG. 1A. the collecting bag is formed in a similar way wherein the tensioning and locking mechanism 16 (which does not include the tube 15 in this example) is operable to release and unreel the collecting fabric 11 from the fabric bearing rod 19 and to form a collecting bag.
In an example, the stabilizing brackets or arms 14 are to secure the supporting legs in at least one tilting angle in which the collecting fabric 11 is at least partially unreeled from the fabric bearing rod 19.
In an example, the hinge member 13c which connects the lower end of the supporting legs 13 to the printer or printer base 12 is shaped to hold the supporting leg 13 in at least one tilting angle, tilted away from the printer.
In an example, as illustrated in FIG. 3. the hinge member 13c is shaped to hold the supporting leg 13 in three different tilting angles: one which is most tilted away from the printer 18 so that the collecting fabric 11 can be hold in a flat, tensioned shape, one which is intermediate so that the unreeled collecting fabric 11 can form the collecting bag. and one, close to the printer 18, which forms a stowing position for the convertible printed product collecting assembly 10.
