Definitions

• the invention relates to a household appliance having a first housing part which has at least one latching means and a second housing part, which has at least one counter-latching means, which latching and counter-latching means are designed for connection of the housing parts and securing means are provided by which the at least one latching means against loosening is secured by the at least one counter-locking means.
• a locking device for fastening a first body which is hineinsteckbar in a second body, wherein a first wall of the first body extends substantially at right angles to a second wall of the second body, with a latching projection, on one of the second
• Body disposed inside of the first wall is arranged, and which can be pushed into a latching opening by a force exerted by a connecting means connected to the first body connecting means.
• a security agent is for each rest and
• Locking means is prevented by the counter-locking means.
• the object of the invention is to simplify the assembly of the housing parts with a generic locking device for the manufacturer. Furthermore, an unwanted disassembly should be made difficult or detectable, for example, by the end user.
• a disassembly for the locking and Jacobraststoffthetic in a nondestructive manner and for the securing means to be destructively possible is achieved in that the securing means is at least one connecting means forming an interference fit.
• the securing means is activated by the latching assembly of the housing parts, i. the connecting means connected.
• the locking means are locked with the counter-locking means.
• a release of the locking means of the counter-locking means is prevented in that the once assembled connecting means can not be solved by the tight interference fit without its destruction again.
• the assembled connecting means hold the two housing parts together in such a way that the locking means can not be released from the counter-locking means. A separation of the two housing parts is possible only if the connecting means is destroyed.
• the latching means can be separated from the counter-latching means even without their destruction.
• the advantage of this is the fact that two assembled housing parts can be reassembled after their separation and the unscathed locking means in cooperation with the unscathed counter-locking means again reliably hold the two housing halves, even if the function of the securing means is no longer guaranteed. This circumstance makes it possible to use once dismantled housing parts again, without having to replace them with new housing parts.
• the locking means and the counter-locking means are designed so that they are destroyed in an attempt to re-separate the two housing parts. This prevents that housing parts whose securing means are already destroyed are reused. Without functioning locking means and counter-locking means, the housing halves can not be held together. It is thus ensured that always be used after disassembly of the housing new housing halves.
• the at least one connecting means may preferably be one on the first housing part having provided pin which is pressed into a provided on the second housing part pin receptacle. Due to the pressed-seat of the pin in the pin holder a frictional connection is created.
• the pin may be any suitably shaped elongate means which may be inserted into a body ie into the pin receptacle such that this means is retained therein due to the frictional force between the outer surface of the elongated means and the inner surface of the body. Common means are pressing pins, which are pressed into a hub.
• the pin has a circular cross section and the pin receptacle on a hollow cylindrical inner wall. So is the smallest size of pin and
• Pen recording created the greatest possible contact area between pen and pen holder.
• the pin can also have other cross-sectional shapes, such as a triangular, square, rectangular or star-shaped cross-section.
• the pin receptacle is conformed to the cross-section of the associated pin, so it may also have a triangular, square, rectangular or star-shaped contour.
• the cross section of the pin is slightly larger than the associated cross section of the pin holder.
• the circular cross section of the pin thus has a slightly larger diameter than the hollow cylindrical inner wall of the pin receptacle.
• the pin receptacle is formed by tubular projections on an inner wall of the second housing part.
• the housing is made of plastic
• the pins or the pin receptacles can be molded onto their respectively assigned housing parts. The molding takes place inexpensively, preferably in the plastic injection molding process.
• the pins and pin holders can also be subsequently molded or glued or soldered, welded. Soldering or welding can be used in particular if the housing parts are made of metal or aluminum.
• the pin has a stop which abuts in a mounted state of the first and second housing part on a counter-stop on the pin receptacle.
• Stop and counter stop ensure that the housing parts are mounted at a predetermined distance from each other. In particular, it is ensured that in a joining operation of the housing parts, the base surface in the interior of the pin receptacle does not press against the end face of the free end of the pin. Thus, the pin remains free of axial compressive forces and also the base inside the pin holder is not pressed by the pin from the inside out, which would make visually unattractive deformations, for example, in plastic housing parts.
• the stop can be formed by a frusto-conical diameter extension of the pin.
• the counter stop element is a hollow truncated conical diameter narrowing of the pin receptacle. Stop and counter stop element thereby form a conical seat between the pin and the pin holder, which ensures a secure and centered fit of the pin in the pin holder.
• Each latching and counter-latching means connection may be associated with a separate connection means. At least each locking and Jacobraststofftagen should be assigned a single connection means. But it can also be associated with each locking and Jacobraststoffharm two or more connecting means. Only in exceptional cases, it may be sufficient that less connecting means are provided as latching and Jacobraststoffharmen.
• the first and second housing part are two shell-like housing halves of a hand blender or hand mixer.
• six locking and Jacobraststofftechnik159 are each provided with an associated connection means.
• Two locking and Jacobraststofftagenen are provided at an upper end of the hand blender.
• Two further locking and Jacobraststofftagenen are provided at a lower end of the stick mixer.
• the last two of the six locking and Jacobraststofftagenen are provided approximately at mid-height of the hand blender.
• the latching means may be formed, for example, as elastic spring tongues which have openings in which engage as latching hook formed counter-latching means.
• two or three mutually parallel openings may be provided on a spring tongue, in which engage a corresponding number of two or three locking hooks.
