The present invention relates to quick-fixing elements that may be employed in, for example, appliances such as dishwashers, baking ovens, or the like. More specifically, the present invention relates to a quick-fixing element for fixing guide rails to horizontally running rods of a grid-type side part, which rods are bent away at an angle from a guide rail in an end region of the guide rail.
Quick-fixing elements of the type in question are known per se, for example from DE 200 10 037 U1.
While such quick-fixing elements are primarily used for securing guide rails in domestic appliances, such as dishwashers, baking ovens or the like, they may also be used in other furniture items as well.
In the case of the grid-like side parts, which are formed from wire or rods, a plurality of horizontal rods running parallel to one another is provided. The rods are angled in their end regions in such a manner that the angled sections protrude in the direction of a side wall of a domestic appliance or of an item of furniture from a fixed guide rail.
The present invention is based on the object of providing a quick-fixing element of the type in question which permits satisfactory securing of a guide rail to just one horizontally running rod of a grid-type side part.
This object is achieved according to the invention in that the quick-fixing element has a first clip-type retaining section, which partially engages around the longitudinal length of a rod. The quick-fixing element also includes a second clip-type retaining section, which partially engages around the rod at an angled end region of the rod. The quick-fixing element may be pushed in the horizontal direction onto the end region of the rod.
This design enables a guide rail to be secured—with respect to the longitudinal axis of a horizontally running rod—in a manner that resists twisting or tilting, since the quick-fixing element forms a means of resisting tilting by its second clip-type retaining section, among other features. The second clip-type retaining section partially engages around the rod at its angled end region. Since corresponding quick-fixing elements are used to secure a guide rail to a rod in both end regions of the guide rail and therefore also to the rod, both end regions of the angled rod are engaged because they are surrounded by the quick-fixing elements. Therefore, not only is a securement against twisting or tilting obtained, but a longitudinal displacement of the guide rail part secured to the rod also is prevented. In other words, because they each engage the rod both along its length and also at a point adjacent to the angled end section, the quick-fixing elements discourage rotation of the guide rail with respect to the rod. In addition, the quick-fixing elements discourage sliding of the guide rail along the length of the rod.
An unintentional release of the quick-fixing element from a rod may be avoided in one embodiment because the quick-fixing element is clamped strongly on to the rod by frictionally engaging the rod.
In another embodiment, to avoid an unintentional release of the quick-fixing element from the rod, a limb of the retaining section may be equipped with a resilient latching tongue. The resilient latching tongue engages around the rod in its longitudinal extent region the quick-fixing element is pushed on the rod, the resilient latching tongue bears against a region of the rod that faces away from the guide rail.
In the case of this solution, a certain form-fitting connection against unintentional release of the quick-fixing element from a rod is achieved. However, since the latching tongue is resilient, with the use of a certain amount of effort, an intentional release of the quick-fixing element and therefore of the guide rail from the rod may be brought about, as may be required, for example, for the purpose of cleaning both the guide rail and the grid-type side part.
Further features of the invention will be described in greater detail below.
An exemplary embodiment of the invention is illustrated in the attached drawings and is described in more detail below.
In the drawings:
While the invention is described in connection with specific embodiment(s), the invention is no intended to be limited solely to the embodiments described and illustrated. To the contrary, the invention is intended to encompass any variations and equivalents apparent to those skilled in the art.
Quick-fixing elements 4 are fixed to the body rail 2 in the end regions thereof.
The rod 5 is bent away at an angle in its end regions in relation to the guide rail 1, with the bent-away end regions 5a extending approximately at right angles to the guide rail 1 in the exemplary embodiment illustrated. Of course, angular ranges other than 90° may be employed without departing from the scope of the invention.
The quick-fixing elements 4 each have a first clip-type retaining section 4a, which partially engages around the rod 5 in its longitudinal extent region. The quick-fixing elements also have a second clip-type retaining section 4b, which partially engages around the rod 5 in its angled end region 5a. In this contemplated embodiment, the clip-type retaining sections 4a and 4b are designed in such a manner that each quick-fixing element 4 may be pushed in the horizontal direction onto the end region of a rod 5.
The respective retaining sections 4a and 4b are approximately C-shaped in cross section, as
In the embodiments contemplated, the quick-fixing elements 4 are fastened to the body rail 2 by welding or the like. The guide rail 1 is secured in relation to the rod 5 to avoid tilting or twisting of the guide rail 1 with respect to the rod 5. This securement is facilitated by the engagement of the second clip-type retaining region 4b of each quick-fixing element around the angled end region 5a of the rod 5.
In addition, this type of fixing prevents a relative longitudinal displacement of the body rail 2 in relation to the rod 5.
The quick-fixing elements 4 are each provided with a clearance cut 9 in the transition region between the longitudinal extent region of the rod 5 and the angled end regions 5a of said rod 5.
By means of the quick-fixing elements 4 according to the invention, there is the possibility of securing guide rails 1 to just one rod 5 of a grid-type side part in a manner that is secure against twisting and tilting.
As
A welded end stop 10 is provided instead of as previously customary. The welded end stop 10 is a cast stopper at one end of the running rail 3. A deployed folding tab 11 is provided at the other end of the running rail 3 to secure a baking tray, a grate, a juice pan or the like on the running rail 3 in the direction of displacement. Such a guide rail may be produced particularly cost-effectively without ultimately incurring functional disadvantages. Of course, other guide rails 1 also may be used in conjunction with quick-fixing elements 4 according to the invention.
The quick-fixing elements 4 are preferably produced from metal. In this case, a single-piece manufacturing is preferred. The design of the quick-fixing elements 4 makes it possible to produce the quick-fixing elements 4 at particularly reasonable cost as punched and bent parts.
The latching tongue 8 is advantageously formed by means of a section punched out of the material of the lower limb 6.
