The invention relates to a hand stamp comprising a housing and covers the body moved against the force of the spring action lettered bracket having a shoulder directed through the side walls of the housing and the at least one located with the possibility of displacement in the horizontal direction in one of the shoulders of the locking element, which is in communication with at least one locking kerosene lateral wall of the body.

Of AT, IN, 384999, as well as AT, IN, 390230 known hand stamp having samarraie device for literal-block movably installed in the housing, and a rotary mechanism for him; so that when the hand stamp to turn lettered block in the position of die stamping and woodblock, it is rotated by the rotation mechanism 180oand moves; the manipulator serves as a bracket, which is connected in this famous stamp with a hollow handle, a cavity which is a pipe connected with the casing stamp intermediate spring. To lock the stamp in different positions, that is, to secure the bracket relative to the housing, the handle has a latch, having the ability to move inward and able to enter into one of several locking grooves on the inner tube. So you can fill stamp paint in a fixed intermediate position or to change interchangeable literal made, for example, in the form of tapes. In order to lock or release the bracket, you need one hand to hold the stamp, and the other hand to move the latch.

In addition, there are stamp, usovershenstvovannymi arm. Although the locking element intended for fixation of various provisions of the stamp, made in the form of horizontally transferred lock, the lock is located on one of the shoulder bracket. This clamp can be pressed into a separate, located perpendicular to the adjacent side wall of the case is one of several locking grooves on the side wall of the housing, and the lower edge of the locking grooves made passing under a reverse angle to the surface in order to direct the latch out again, if the bracket is moved further along the body. To release the clamps she just pressed down, allowing the latch slides along the inclined surface of the locking groove to the outside, and the bracket can again move freely.

However, the described hand-stamp, among other things, have also another disadvantage that arises lateral force on the latch located on the one hand, due to the force of the spring acting between the bracket and the housing, which may result in the release latch to bias the shoulders brackets on the side walls of the housing. In addition, the disadvantage is that the latch made in the form of the I which the bracket must be provided by a separate bearing.

The objective of the invention is to provide a hand stamp the aforementioned type, the locking device which is simple in construction and manufacture, which is easy to use with one hand and which is not skew the shoulders brackets on the side walls of the housing.

Hand stamp according to the invention differs in that the locking groove on its upper edge provided with a notch, and that the locking element is designed as an elastic tongue, the free end of which may be pressed into the locking groove and coupled with the recess. This solution can eliminate the need for a separate element for blocking and releasing the hooks located for movement; a spring tongue is essentially rigidly connected to the shoulder bracket that provides a significant simplification of the manufacturing process. By performing the notches in the locking groove ensures a secure grip of the tongue, regardless of its elasticity.

A special advantage is that the tongue is located in a through hole of the shoulder bracket, so that the tongue is protected from damage and can be located within the contour of the shoulder bracket with virtually no interference.

In order to most effectively prevent distortion of the shoulders brackets on the side walls of the housing is preferred, if the tab is located on both arms of the bracket. Bilateral fixing or arresting, achieved, due to the presence of springy tongues as the locking elements can be done with one hand.

Also favorable is when the tongue is in the off position in the area bounded by the wall thickness of the shoulder bracket, which guarantees that the free end of the tongue may not involuntarily to get into the slot in the locking groove.

To facilitate coupling the free end of the tab with the notch in the locking groove is also preferred, if the free end of the tongue is made sharp. This ensures accurate entry of the free end of the tongue into the groove. For easy control of the tongue when fixing can be beneficial, if the tongue has a thickness in the portion that serves as a manipulator, and this part is near the free end, and catolina adjacent areas which is the connection to the shoulder bracket, at the same time simply provides springy property tabs.

In this relationship, given the simple manipulation of the stamp or control them, is also favorable if the outer side of the tongue, starting from the pointed free end, made in the form of a convex push button.

In addition, it is preferable that the inner side of the tongue facing the lateral wall of the body was tilted at an acute angle, for example from 1oto 5opreferably about 3oto the plane of the inner side of the arm bracket with increasing tilt outward and upward. Due to this event further guaranteed that the free end of the tongue is in its off position cannot inadvertently fall into the locking groove by groove. In addition, the longer the course of the spring and favorable increases due to this force spring force or the force of return of the tongue, allowing the tongue with greater reliability upon release from the notch returns to its non-operating position.

It is preferable that a through hole and tongue were made rectangular. Due to this the mA.

Is favorable in terms of choice of podpruzhinennom and size of the tongue, if the tongue on the adjacent plot has a thickness equal to approximately half of the thickened part, which is the button.

Below the invention is explained in more detail with the help of particularly preferred exemplary embodiment shown in the drawing, which it, however, should not be limited.

In Fig. 1 shows a hand-stamp, a front view, with the housing of the stamp shown with thick lines, and bracket - thin lines;

Fig. 4 is an enlarged fragment of the locking device in cross section; and

Fig. 5 - the image corresponding to Fig. 4, a modified locking device.

Hand stamp, completely marked with the position 1 in Fig. 1 to 3, includes a housing 2 and the bracket 3, the covering body 2, two shoulder 4 which are arranged to move along the side walls of the housing 2, having a frame shape, and overcome the counteracting force of the spring 6. Spring 6 when it leans with one hand on the housing 2 and on the other hand n is th non-working position in the lower working position and rotates also at an angle of 180o. Reasons of clarity, image not shown, as they are in themselves known and need no detailed explanation, the elements forming mechanism of rotation of this hand stamp 1 and lettered wheels, lettered tape, push plate, zamarramala pad and so on. For more detailed explanations here you can refer to the patent AT, IN, 384999.

For fixation bracket 3 in different positions in height when it is moving relative to the housing 2 for the purpose of regulating lettered wheels for refilling ink pads or outside, or in the working position on the shoulders 4 of the bracket 3 are fixing elements in the form of spring tongues 7. Each of these reeds 7 can be pressed into the locking groove 8 of the respective side wall 5 of the housing 2, which will be explained in more detail below, and their implementation is best seen in Fig. 4 in an enlarged image, where the tongue 7 is shown in the off position. The free end 9 of the latch 7 are pointed up and quickly goes down in thickness in the part 10, which serves as a pointing device, made in the form of a convex button 11. The lower adjacent section 12, following the thickened part 10 has a thickness which>/P>The tongue 7 is located in a through hole 13 in the arm 4 and formed with its lower end in one piece with the shoulder 4. The bracket 3 and thereby also the tongue 7 is made of appropriate plastic, preferably ABS, injection molding or injection molding. It is also possible to perform the pull-tab 7 in the form of a metallic flat spring, equipped with a pushbutton and fixed accordingly in pass-through hole 13 on the shoulder 4, for example, inserted into a slot, glued, and so forth.

As can be seen in Fig. 2, a through hole 13 and the tongue 7, are made slightly smaller, have a rectangular shape. Position 14 marked the hole in the side wall 5 of the housing 2 that serves as a rocker control for is not shown here in more detail the mechanism of turn of the hand stamp 1.

According Fig. 4 of the said locking groove 8 in the side wall of the housing 2 (Fig. 4 shows in phantom line) made passing obliquely inward and upward and provided with a notch 15, the shape of which conforms to the shape of the tip 9 of the latch 7.

In the exemplary embodiment shown in the drawing, three corresponding locking grooves 8 are located in the middle of the side wall 5 opposite aawki 8 may be intermittent, that is to be executed in the respective side wall 5 of the housing of two parts of the grooves on both sides of the middle longitudinal grooves 16; longitudinal grooves 16 serve as usual for directions lettered axis.

In addition, in the off position of the tongue 7, as shown in Fig. 4, it is seen that it is within the limits specified wall thickness of the shoulder 4, and the inner surface of the tongue 7 from the adjacent side wall 5 of the housing 2 is held at an acute angle equal to, for example, 1o-5opreferably about 3oto the plane of the inner side of the arm 4 is inclined outward and upwards.

In Fig. 5 shows a modified form of the locking device, the free end 9 of the latch 7 which is made in the form of a hook, and the tongue 7 is made in one piece with the shoulder 4 of the bracket 3 at its upper end, instead of performing at its lower end according to Fig. 4. This thickened area of the material adjacent to the end of the tongue 7 having the form of a hook, also forms a push button 11.

From the upper flow position, shown in Fig. 1, the bracket 3 can be moved manually down with overcoming the action of the spring 6 until such time as it takes with the tabs 7 telemag and fingers to push buttons 11 thus, that the free ends 9 of the tongues 7 thibaudia and engaging corresponding locking grooves 8. If now slightly reduce the pressure on the bracket 3 while maintaining pressure on the push button 11, the bracket 3 will move under the action of the spring 6 upward so that the sharp free ends 9 of the tongues 7 will come in the notches 15 of the locking grooves 8 so that the bracket 3 is fixed (see, for example, in Fig. 3 the bracket is fixed in the lower position). Similar to this occurs in the execution according to Fig. 4 and 5. The difference between these variants perform is that in the embodiment of Fig. 4, the tongue 7 is loaded in the locked position by the spring 6 in the longitudinal direction of the compressing force, and in the embodiment of Fig. 5 - force stretching.

To release the clamps need is so pressing the bracket 3 from the housing 2 so that the free ends 9 of the tongues 7 under the force of elasticity of the tongues 7 and, if necessary, by sliding along the inclined inner surface of the locking grooves 8 under the action of a spring force came out from under the upper cut edge of the locking grooves 8 back in the off position, allowing the bracket 3 will again have the opportunity to free bus, spring-loaded and mounted for movement relative to it, equipped with guided along the side walls (5) of the housing (2) shoulders (4), and at least one locking element can be moved in the horizontal direction on one of the shoulders (4) bracket (3), adapted to communicate with at least one locking groove (8), performed on the adjacent side wall (5) of the housing (2) and fixing brackets (3) in a given position on the path of its movement along the housing (2), characterized in that the locking groove (8) at its upper edge has a recess (15), and that the locking element is designed as springy tongue (7) the free end (9) which is adapted to step into the locking groove (8) and coupling with a recess (15).
