Patent Application
20050072890
The invention pertains to a hanger according to the introductory clause of Claim 1.
Hangers of this kind can be used to suspend elements from a rail arrangement and to guide them so that they can be moved back and forth. In most cases, a support roller guides the hanger along the top of a rail, which is attached to a substructure.
A hanger of this type is known from U.S. Pat. No. 1,116,331. An adjustable keeper device is provided between the roller guided on the rail and the point where the movable element is attached to the hanger. The outward-extending, multi-part design of the hanger requires a complicated production procedure and is not optimal with respect to the economical use of material.
It is therefore the task of the present invention to create a hanger according to the introductory clause of claim 1 which forms a compact and visually attractive unit within the smallest possible space without sacrificing any of the previous ability of a hanger of this type to serve various applications and to fulfill different functions.
This task is accomplished by the features stated in Claim 1. Advantageous embodiments of the object of Claim 1 can be derived from the subclaims.
With the hanger according to the invention, it has become possible, through an advantageous combination of the amount of material used and the external shape of the hanger, to create a unit which is both functional and visually attractive at the same time. A convex surface and rounded ends make it possible to construct a thin hanger of limited length, so that a compact unit is created. A hanger designed in this way makes it possible to utilize the construction space available in optimal fashion and also to optimize the production process and the amount of material used.
Although the amount of material required for the hanger according to the invention is extremely small, the stability and functional properties of the hanger are nevertheless ensured. The resulting outer contours have flowing transitions and therefore present an attractive appearance. All corners and edges are provided with radii. All thicknesses are reduced to a minimum. The flowing outlines of the outer contours, especially of the front and edge surfaces, considerably reduce the amount of material required and also reduce the problems associated with casting. Metal materials, plastics, and even so-called hybrid materials can be used. There are almost no restrictions on color. The properties mentioned also contribute greatly to the reduction of production costs.
Because the fastening shoulders/areas for the rollers and the connections to the suspended element or other attached components are covered, an advantageous visual concept is created, which harmonizes especially well with the clear, transparent appearance of dematerialized glass-metal construction. The fastening areas on the front and/or rear are protected by covers, so that no dirt which could interfere with operation can intrude. The hanger has no projecting or sharp-edged parts, which facilitates cleaning and eliminates any source of injury associated with the hanger.
The hanger has basically a flat, elongated shape with a middle section extending between two opposite ends. The two end areas are semicircular. The middle section is of uniform width, which continues into the two end areas and is equal to the diameter of the semicircles at the end.
The surface of the hanger facing the observer is not interrupted by any functional elements. The surface is slightly convex both in the longitudinal area between the ends and also between the lateral edges, from which the surface rises to form a slight elevation above the surrounding sides. Overall, a smooth, visually uniform surface is created. In the middle section, a cover, which conceals the area where a keeper is attached to the rear, fits flush with the surface.
On the rear surface facing away from the observer, a roller is attached to a bearing body at the upper end of the hanger. The roller guides the hanger on the rail so that the hanger can move back and forth. The bearing body is concealed from the observer by the rounded end area. At the bottom end, there are two point holders on the rear for the attachment of the element which is to be guided movably on the rail. These point holders are attached to shoulders connected to the hanger and are also concealed from the observer.
The keeper located on the rear surface of the middle section prevents the hanger from jumping off the rail unintentionally. After the hanger has been set on the rail, the keeper device is mounted and attached from the front side. In addition, a stopper can be mounted on the side of the hanger to ensure that the element comes to rest gently and without noise against an appropriate limiter. Fastening means/openings are required on the rear surface for both of these functions. So that a visually uniform surface can be achieved here as well, this area is concealed by a cover. At the same time, dirt is prevented from intruding into this area, where it could interfere with the operation of the unit.
Additional details of the invention can be derived from the following preferred embodiments, which are described on the basis of the drawings:
In
The hanger 1 has a basically flat, elongated shape with a middle section 9 extending between two opposite end areas 7 and 8 and forms a single unit with them. The two end areas 7 and 8 are designed as projecting semicircles. The middle section 9 has a uniform width B, which continues into the two end areas 7, 8 and is equal to the diameter D of the semicircular end areas 7, 8.
The surface 10 of the hanger 1 facing the observer is not interrupted by any functional elements and is slightly convex; that is, the surface 10 rises inward to form a slight elevation above the surrounding edges 11. The transitions between the end areas 7, 8 and the middle section 9 are emphasized visually by transverse grooves 12. In the middle section 9, a cover 13 is integrated so that it fits flush with the surface 10. The cover 13 conceals the area where the keeper 5 is attached to the rear surface.
On the rear surface 14, i.e., the surface facing away from the observer, the roller 3 is attached to the upper end area 7 of the hanger 1; this roller guides the hanger 1 along the rail 2 so that the hanger is free to move back and forth. The roller 3 is supported by a bearing body 15 connected to the hanger 1. This bearing body is circular and has the same diameter D as the semicircular end area 7. The bearing body 15 is thus concealed from the outside observer by the end area 7.
At the bottom end area 8, there are two point holders 4 on the rear surface for the attachment of the element which is to be guided movably on the rail 2. The point holders 4 are attached to shoulders 16, which are themselves connected to the hanger 1 and include appropriate fastening means. The shoulders are circular in shape. The diameter D of the shoulders 16 corresponds to the maximum width B of the hanger 1 or to the maximum diameter D of the semicircular end area 8, which means that the shoulders 16 are concealed from the observer by the end area 8.
The keeper 5 located on the rear surface of the middle section 9 prevents the hanger 1 from jumping unintentionally off the rail 2. After the hanger has been set on the rail 2, the keeper 5 is mounted and attached from the front side. A stopper 6 can also be mounted on the side of the hanger 1 to ensure that the element comes to rest gently and without noise against an appropriate limiter. Fastening means/openings are required on the rear for both options. So that a visually uniform surface can be created here, too, this area is concealed by a cover 17. At the same time, dirt is prevented from intruding into the area and causing malfunctions.
The above description of the exemplary embodiments according to the present invention serves only to illustrate and not to limit the invention. Within the scope of the invention, various changes and modifications are possible without exceeding the scope of the invention or its equivalents.
