Definitions

• the present invention relates to a door handle for a household appliance.
• door handles are known in various forms.
• So z. B. a known from DE 10 2005 037 891 A1 door handle a handle in the form of an elongated tube and two handle holder.
• the handle holders each comprise a head insertable into an open end of the tube and an arm extending transversely of the insertion direction from the head connecting the handle to the door, e.g. a free end of the arm is attached to a side edge of the door.
• the handle can extend over the entire height of the handle, it is provided at its ends with two slots through which the arms extend in the assembled state.
• the heads of the handle holders must be made slightly oversized and press fit into the open ends of the handle.
• the handle must be made of a strong material and high wall thickness, otherwise the heads spread the slotted ends of the handle on. In extreme cases, this can cause the handle is no longer tight. However, even a minimal deformation at the ends of the handle, which does not affect its tight fit, is disturbing to the user, as it can lead to a conspicuous distortion of light reflections on the surface of the handle.
• a door handle for a household appliance with an elongated, at least one end provided with a slot handle and at least one handle holder for connecting the handle to a door, wherein a head of the handle holder engages through the slot in the handle supporting an elastically deformable clamping member engaging excessively in a non-slotted portion of the handle. Since the non-slit portion can not yield to the pressure exerted by the clamping member by expansion, a deformation in this section is omitted, even if the handle is thin-walled and / or formed from an easy-to-bend material such as aluminum or plastic. Since the head in the slotted portion of the handle need not have excess, deformation can be avoided here as well.
• the clamping part has a spherically shaped outer surface.
• the tip of the clamping member can be easily inserted into the handle with a certain play, and a frictional engagement between the clamping member and the handle is formed only when the clamping member has already penetrated a little way into the handle.
• the clamping member comprises a plurality of spaced apart by slots elastic tongues.
• the elastic tongues can be bent elastically when pushing the handle on the handle holder to then hold the handle frictionally.
• the clamp can be realized by a single molded part, in particular made of plastic.
• a hollow handle in particular made of aluminum, can be used, which has a wall thickness of less than 2 mm.
• a durable clamp attachment can be achieved even with a small wall thickness, without the risk of deformation of the handle exists.
• the hollow handle can be made particularly easily as an extrusion profile.
• Fig. 1 is a schematic representation of a door of a household appliance, to which a
• Figure 2 is an exploded view of a door handle according to the invention at one end of a handle.
• FIG. 3 shows a section through an edge of a door with door handle attached thereto according to a preferred embodiment
• FIG. 4 shows a section through a handle holder of the door handle from FIG. 2 with an attached clamping part, along a plane A-A from FIG. 2.
• a door 1 of a household appliance is shown schematically, on which an inventive door handle 2 is mounted.
• the door handle 2 comprises an elongated tubular handle 3 and two identically constructed mirror-like handle holder 4, which are attached to two ends of the handle 3.
• the handle holder 4 are each with one remote from the handle 3 end mounted on a side edge of the door 1, for example by means of screws and hold the handle 3 from a user of the household appliance facing the front of the door 1 spaced so that the user can grip the handle 3 with one hand.
• the door handle 2 is positioned on the door 1 such that the handle 3 is disposed parallel to a vertical edge of the door 1 adjacent thereto and projects forward beyond the front of the door 1.
• a lower end of the door handle 2 is explained in detail below with reference to Figures 2 to 4.
• An upper end of the door handle 2 is constructed in mirror image.
• FIG. 2 shows the individual components of the door handle 2 in an exploded arrangement.
• the lower end of the door handle 2 comprises a handle holder 4, a clamping member 5, a fitting 6 which are adapted to be held together by a screw (not shown in Fig. 2), and the handle 3, of which only a lower portion is shown is.
• the handle 3 consists of a hollow aluminum tube with a thin wall 30 and a non-circular, here formed as an intersection of two circles with different radii cross section.
• the wall thickness of the wall 30 is between 1, 5 mm and 2 mm. Due to its hollow shape, the handle 3 can be manufactured in a very simple manufacturing process by an extrusion process.
• the wall 30 has a rectangular slot 31 open towards a lower edge 36 of the grip piece 3, so that the grip piece 3 can be divided into a slotted portion 32 and a non-slotted portion 33.
• the handle holder 4 has a head 41 whose cross-section corresponds to that of an inner cavity 34 of the handle 3, so that the head 41 in the assembled state, the inner space 34 in section 32 fills the exact fit.
• the arm 42 From the head 41 is an elongated shaped flat arm 42 radially outwardly, the arm 42 near its approach to the head 41 has a slightly curved course and on a side facing away from the head 41 flat end adapted to a lateral contour of the door 1 Recess 46, so that the flat end on a side edge of the door 1 with two screws (not shown here) can be mounted.
• the type of attachment to the door 1 and the exact shape of the arm 42 may vary depending on the structural conditions of the household appliance.
• the dimensions of the arm 42 in the approach area at the head 41 correspond to the dimensions of the slot 31 on the handle 3.
• At one of the handle facing upper surface of the head 41 is surrounded by a flat edge surface 44 survey 43 formed.
• the survey has a like the head 41 and the handle bar itself a non-circular cross-section. From the center of the elevation 43, a threaded blind bore 45 extends into the head 41.
• the handle holder 4 is adapted to carry a clamping part 5.
• the outer surface of the clamping member 5 connects at its lower edge continuously to that of the head 41 and is slightly spherically shaped, i. the outer cross section of the clamping member 5 is slightly larger in the middle than at its upper and lower ends.
• the clamping part 5 consists of a stiff, to a small extent elastically deformable plastic material.
• a lower region of the clamping part 5 forms a base 54, in which a recess is formed from below, wherein the recess has a complementary shape to the elevation 43, so that the base 54 can be placed on the head 41 in an exact fit and against rotation.
• An encircling wall of the base 54 merges upward into a plurality of tongues 51, which surround a cavity 53 in an upper region of the clamping part 5.
• Outer surfaces of the tongues 51 are in the shape of elongate trapezoids, which narrow at ends remote from the base 54, so that the tongues 51 are separated from one another by slots 52.
• the cavity 53 is adapted to receive the fitting 6, which also has the previously described flattened round outer cross-section.
• the fitting 6 comprises a disc 61, from which a cylindrical projection 63 protrudes. Disk 61 and projection 63 are traversed by a central bore 64.
• the base 54 has on a surface facing the cavity 53 a bore 6 complementary to the fitting piece, so that the fitting 6 can be positively inserted into the clamping part 5 so that the projection 63 engages in the bore.
• the base 54 of the clamping part 5 is placed on the head 41 of the handle holder and the fitting 6 is inserted from above into the cavity 53 of the clamping part.
• the projection 63 comes into contact with the elevation 43 of the head 41.
• a screw (not shown) is inserted from above through the holes 64 and 45 and tightened. The contact between the projection 63 and the projection 43 prevents the base 54 from widening when the screw is tightened too tightly.
• the handle 3 is then pushed from above onto the handle holder 4 with attached clamping part 5, so that the clamping part 5 is completely covered by the wall 30 of the handle and the shaft 42 engages positively in the slot 31.
• a lower edge 36 of the handle aligns with the bottom of the base 54, so that the clamping member 5 is completely covered by the wall 30.
• the tongues 51 of the clamping part 5 are flexible due to the plastic material, they can shrink slightly during insertion of the clamping part 5 in the interior 34 of the handle 3 to the cavity 53 of the clamping member 5 out. Since the maximum cross section of the clamping part 5 exceeds the cross section of the inner space 34 of the handle 3 minimally, when pushing the handle 3 on the clamping part 5, a certain force must be expended to bend the tongues 51 inwardly.
• the handle 3 has reached its end position on the handle holder 4, the outside of the clamping member 5 is positively clamped to an inner side of the wall 30. The clamping takes place here in the section 33 of the handle 3, which is not slotted.
• FIG. 3 shows a section through an edge region of the door 1 with a door handle attached thereto. From the clamping part 5 inside the handle 3 in this case only ends of the tongues 51 can be seen.
• the fitting 6 is inserted into the clamping part 5 and the screw 7 is inserted from above through the clamping part 5 into the provided on the fitting 6 and the handle holder 4 holes.
• FIG. 4 shows a section through handle holder 4, clamping part 5 and fitting piece 6 in the assembled state, along a plane AA from FIG. 3. It can be seen here that the projection 63 protrudes on the fitting part 6 through the recess on the base 54 of the clamping part 5 such that a lower surface of the projection 63 comes to lie on a surface of the projection 43 on the head 41.
• the door handle 2 is mounted on the door 1 only by a handle holder 4 attached to the end of the handle 3, in which case the handle 3 can be made shorter than in the described embodiment and has a free end.
• the handle of the holder 4 opposite end of the handle 3 is suitably closed either by a decorative cap, or the end of the tube is executed closed.
