Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The invention will be explained in further detail hereinafter by means of an exemplary embodiment to which it should not be restricted however and with reference to the drawings. The drawings show in detail:

(2) FIG. 1 shows a perspective view of a hand-operated stamp from above according to the invention in which, inter alia, a bottom side, a broad side and a narrow side which has a locking element can be seen;

(3) FIG. 2 shows the hand-operated stamp from FIG. 1 from above;

(4) FIG. 3 shows a sectional view through the hand-operated stamp along the line III-III shown in FIG. 2; and

(5) FIG. 4 shows an enlarged view of the detail D from FIG. 3.

(6) FIG. 1 shows a hand-operated stamp 1 which is configured as a self-inking stamp with inking in an upside-down position, in a view partially from below, i.e. on a bottom side or imprint side. FIG. 3 shows the same hand-operated stamp 1 in a sectional view along the line of intersection III-III shown in FIG. 2. The hand-operated stamp 1 has a housing 2 in which a stamp unit 3 with a stamp plate 5 mounted on a plate carrier 4 is mounted. Alternatively or additionally to a stamp plate 5, a type unit not shown could also be provided. In the example according to FIG. 1 and FIG. 3, the stamp plate 5 is arranged in an imprint opening 6 at the bottom-side end of the housing 2, i.e. the hand-operated stamp 1 is shown in a space-saving delivery position. In an imprint position the stamp plate 5 would not be completely exposed other than in the delivery position; instead, the printing plate or printing relief of the stamp plate 5 would lie in one plane with the underside of the housing 2, namely in the plane defined, for example, by the surface of the object to be marked. For displacement of the stamp unit 3 between a rest position or stamp inking position of the hand-operated stamp 1 not shown but known to the person skilled in the art, in which the stamp plate 5 rests on an ink pad 7 (cf. FIG. 3) and the imprint position or the delivery position, the stamp unit 3 is coupled to an actuating part 8 which can be displaced with respect to the housing 2. The actuating part 8 or an actuating clip is arranged at least partly above the housing 2 and can be easily gripped by a user and actuated by pressing down from the rest position in the direction of the object to be stamped into the imprint position. A restoring spring 9 shown in FIG. 3 can return the stamp unit 3 from the imprint position into the rest position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(7) It is also clearly recognizable in FIG. 1 and FIG. 3 that the actuating part 8 has a locking element 10 which is arranged on a narrow side of the hand-operated stamp 1 or the actuating part 8. Preferably a second such locking element 10′ is additionally provided on an opposite narrow side of the hand-operated stamp 1 or of the actuating part 8 which cannot be seen in FIG. 1. The locking element 10, 10′ is used to limit a displacement or a displacement path of the actuating part 8 with respect to the housing 2. Thus, with the locking element 10, 10′ the actuating part 8 can be fixed in a defined position in relation to the housing 2. The locking element 10, 10′ has a first actuating direction R1 which corresponds to production of the limitation and the locking element 10, 10′ has a second actuating direction R2 which corresponds to a release of the limitation, cf. FIG. 4. Thus, by moving the locking element 10, 10′ into the first actuating direction R1, the user can fix the actuating part 8 in relation to the housing 2 and by moving the locking element 10, 10′ in the second actuating direction R2, can release the actuating part 8 in relation to the housing 2 and then displace or have it transferred into the rest position by the action of the restoring spring 9.

(8) The locking element 10, 10′ has a first actuating position 11 and a second actuating position 12, wherein the locking element 10, 10 can be moved in the first actuating direction R1 by actuation of the first actuating position 11 and the locking element 10, 10′ can be moved in the second actuating direction R2 by actuation of the second actuating position 12.

(9) In FIG. 1 it can further be identified that the locking element 10, 10′ has a marking 13 at the first actuating position 11 and/or at the second actuating position 12. The marking 13 can, for example, be a lettering or a symbol.

(10) FIG. 4 shows the detail D from FIG. 3 on an enlarged scale in which the locking element 10 can be seen in a locking position which prevents any displacement of the actuating part 8 with respect to the housing 2. The second locking element 10′ not shown in FIG. 4 is preferably constructed in the same manner. The locking element 10 is configured as a rocker element 10a, for example, in the form of a flat rocker switch on a pivot shaft 14. The rocker element 10a is mounted rotatably on the pivot shaft 14, more precisely slidingly mounted on the substantially cylindrical pivot shaft 14. The rocker element 10a comprises the first actuating position 11 on a first side 15 of the pivot shaft 14 and the second actuating position 12 on a second side 16 of the pivot shaft 14. The second side 16 is arranged opposite the first side 15 in relation to the pivot shaft 14.

(11) In the example shown, the rocker element 10a has a hook projection 17 which extends in the first actuating direction R1 and in the assembled state of the hand-operated stamp 1 in the direction of the housing 2. In this case, the hook projection 17 is located on the first side 15 of the pivot shaft 14. In particular, the hook projection 17 engages in a recess 25 in the housing 2 in the locking position shown in FIG. 4.

(12) In the example shown, the actuating part 8 has a first stop 18 for a movement of the rocker element 10a in the first actuating direction R1. The first stop 18 is, for example, configured as an edge which is arranged radially outside the hook projection 17 in relation to the pivot shaft 14. Accordingly, a corresponding projection 19 is provided on the rocker element 10a which is configured to rest on the first stop 18 (edge) when the rocker element 10a is moved sufficiently far in the first actuating direction R1, i.e. into the locking position. The first stop 18 thus limits the movement of the rocker element 10a in the first actuating direction R1.

(13) The actuating part 8 according to the depicted example additionally has a second stop 20 for a movement of the rocker element 10a in the second actuating direction R2. As can be identified in FIG. 4, the first actuating direction R1 and the second actuating direction R2 are mutually opposite directions of rotation. Accordingly, a corresponding contact surface 21 is provided on the rocker element 10a, which is configured for resting on the second stop 20 when the rocker element 10a is moved sufficiently far in the second actuating direction R2, i.e. into the release position. The second stop 20 thus limits the movement of the rocker element 10a into the second actuating direction R2. The second locking element 10′ is also configured as a similar rocker element and shown for illustration in FIG. 3 in the release position. In practice, usually both locking elements 10, 10′ will either adopt the release position or the locking position at the same time. According to the example shown, the actuating part 8 further has a recess 22 for receiving the rocker element 10a, wherein the pivot shaft 14 is arranged in an offset manner in the recess 22 with respect to the housing 2. Thus, a large part of the rocker element 10a is received in the recess 22. In the release position of the rocker element 10a (cf. the second locking element 10′), the outer surface of the rocker element 10a with the actuating positions 11, 12 is substantially inserted in the plane of the flat side wall of the actuating part 8 and does not emerge therefrom.

(14) According to the example shown, the actuating part 8 also has a supporting strut 23 in the recess 22, wherein the supporting strut 23 is arranged parallel to the pivot shaft 14. The supporting strut 23 can be arranged as in FIG. 4 between the hook projection 17 and the pivot shaft 14 and can thereby also serve as a stop for limiting the movement of the rocker element 10a in the first actuating direction R1.

(15) In the example shown in FIG. 3 and FIG. 4 the rocker element 10a is connected to the pivot shaft 14 by means of a snap-on connection 24.
