Definitions
- the invention relates to a connecting element for releasable connection an implement with a work handle or other comparable handle according to the preamble of the claim 1.
- a connecting element is from EP-A-0 234 210 is known and is used in particular to cleaning devices, such as Connect brooms, pug and the like with a handle.
- the latch is rigidly over the outer surface of one part. It can therefore only tilted against the axial direction and inserted into the other part will. It drives the axially against a spring slidable elongated projection in front of it. If the two Parts can be inserted into each other at the intended depth by tilting one part of the latch into the jack receptacle be snapped into place. This will make for the elongated The path is free to engage the recess in the axial direction and lock the two parts together.
- connection is composed of a large number of individual parts.
- EP-A-0 202 362 is a connecting element made of two in the axial direction nested parts known in which a spring tongue one part the wall of the other part outside reaches around and by reaching behind one on the wall arranged rib both parts locked together. once closed this connection is very difficult to release.
- the object of the invention is to provide a connecting element according to the Preamble of claim 1 to create a stable, however easy detachable connection between handle and implement guaranteed, is easy to manufacture and special characterized by low weight.
- the connecting element according to the invention has two collapsible Parts on by means of a latch and a The ratchet holder can be locked in the desired position can, a twisting of the two Parts is excluded. This way it becomes stable non-rotatable connection created by actuating the latch is easy to solve.
- At least one part advantageously has a hollow cross section into which the other part can be inserted.
- the anti-rotation device is attached by a special projection one of the parts formed with a corresponding recess of the other part interacts and by means of a form fit makes twisting between the parts impossible.
- the pawl itself can also serve as an anti-rotation device.
- the pawl has a head that is in a recess on the other part engages as a jack receptacle, this intervention makes it more effective in the circumferential direction Form-fit created, which prevents the parts from rotating.
- the latch must be dimensioned stronger will be and also immobile in the circumferential direction.
- positive locking can also be achieved by another part of the latch, for example a web-like section can be generated, that in the assembled state of the parts in a corresponding Recess of the other part comes to rest.
- the latch is made in one piece with one part train; the necessary mobility of the Latch can be achieved in that the outer surface of the Part has a U-shaped recess, which in the In the middle of the "U", there is a standing pawl which forms the latch and is provided with a projection in the area of the U-base, to lock with the handle of the other part can.
- the handle is also useful integrally formed with the corresponding part, wherein advantageous the jack receptacle as a breakthrough in the Shell surface of the part is designed so that the head of the Pawl protrudes into the opening or even in the locked state, so easy for the user to be released by pressing into the breakthrough.
- the special unlocking option Latch is dispensed with if this is designed that this by a certain force that the normal Actuating force exceeds, again from the jack receptacle can be pulled out.
- the latch is at least in the locked state under spring tension, this Spring tension due to the elasticity of the latch itself or a resilient element can be applied.
- connection For connecting the connecting element to the handle or the tool has a double cross-section.
- a particularly simple and advantageous connection results if the part is provided with a snap-in element is that by pressing into a corresponding one Element can snap into this. That way establish the connection quickly and also disconnect again, being characterized by the shape of the snap-in elements at the same time the degree of freedom of the possible movement lets set. For example, becomes a spherical body used, which is pressed into a ball socket, so allows movement around all axes. On the other hand, becomes a Cylindrical roller used, so there is only a movement around one axis possible.
- the connecting element is in the locked state to see.
- the two parts 1, 2 are up to a stop 3 pushed into each other and locked.
- the first part 1 points an opening 5 as a jack socket in which a head 6b of a latch 6 can be seen.
- This head 6b by the user of the device in the Breakthrough 5 pressed in and the two parts 1, 2 pulled apart.
- the second part 2 can be seen, the latch 6 with the head 6b.
- the second part 2 is in two Sections divided.
- the first section 2a serves the Attachment to the work handle, which will be discussed later, and the second section 2b is used to connect to the first part 1.
- the second section 2b has an im essentially hollow round cross-section pointing towards of the first section 2a on a stop 3 in the form of a Ring collar ends.
- the Latch 6 from an area of the lateral surface of the second Section 2b formed; for this purpose, the outer surface has a U-shaped Recess 7 on a web 6a and the head 6b detaches from the outer surface.
- the head 6b is like out Figure 2, clearly shown thickened, so that this protrudes from the lateral surface in the idle state.
- the elongated web 6a of the latch 6 is a achieved certain elasticity, which of course is strong on the thickness of the web 6a and the material used depends.
- Figures 4 and 5 show the cross sections of the second Part 2 according to sections A - A and B - B in Figure 3. How 4 shows the cross section of the first Section 2a of the second part 2 a so-called Double anchor cross section.
- This cross section is for Suitable for holding plastic handles, which one have corresponding internal cross-section. Grab it elongated projections of the profile of the stem in the elongated grooves 8 of the double anchor cross-section and thus create a non-rotatable connection.
- the illustrated The connecting element is made of a thermoplastic manufactured and has not shown draft to to be able to demold this.
- the first section 2a of the second part therefore does not exactly show the one shown Cylindrical shape, but is slightly frustoconical shaped. This shape allows the stem to be easily placed on the Push the first section 2a up to the stop 3, the Stalk is slightly widened when plugging in the end area and therefore good on the second part 2 of the connecting element holds.
- the rectangular recess 9 has an area that the "U" of the U-shaped recess 7 exceeds. It will possible from the side of the rectangular recess insert this one mold core into the second section 2b, which is also the core for the U-shaped recess 7. Of the entire cavity of the second section 2b, the U-shaped Recess 7 and the rectangular recess 9, which the Anti-rotation forms in this way with a single mold core can be created.
- the first part 1 of the connecting element is closed see the second part 2 with the second section 2b is inserted.
- the first part 1 has a first analog Section 1a, as can be seen from FIG. 7, also with Double anchor cross-section on that with the implement is connectable.
- the implement can by means of Hole 10 in the first section are additionally secured.
- the second section 1b has a substantially round one Hollow cross-section, the lateral surface of which is rectangular Breakthrough 5 for receiving the head 6b.
- FIG. 8 The cross section of the second section in the area of Section D - D can be seen from FIG. 8.
- breakthrough 5 of the jacket can be seen which is on the inside expanded to something to lock the head 6b facilitate.
- the recess 11 in the area of the opening 5 extended this is up to the insertion opening for the second Part 2 continued, as well as using the dashed line can be seen in Figure 6. Through this recess 11 Introducing the latch 6 with the head 6b essential facilitated.
- This recess 11 is opposite elongated projection 12, which in Figure 8 in cross section see is.
- this projection 12 comes in the rectangular recess 9 of the first part and thus prevents twisting of the two parts 1, 2.
- the width of the Projection 12 towards the insertion opening so that the second Part 2 not necessarily in exactly the right angular position must be introduced in the first part 1, but this rather by the projection 12 in the right place Locking the latch 6 is performed.
- the Pushing the parts 1, 2 is not only due to the Locking the pawl 6, but also by the stop 3, at which the end 13 of the second section 1b of the first part 1 comes to rest.
