COMPONENT HOLDER

Abstract

A component holder, in particular for aircraft, for indirectly securing components to the fuselage or body shell. The component holder has a base portion and an attachment element which is lockable to the base portion and has a component receiving member arranged thereon. The base portion has a circular shell form, and the upper edge has retention and locking elements. The lockable attachment element has a s dome-like basic structure, and the lower edge region has retention and locking elements which complement those of the base portion and are lockable therewith. The component receiving member is formed integrally on the attachment element and arranged at a dome zenith on the outer side. The dome is formed from at least three frames which are angularly offset on the circumference. The frames extend from the dome lower edge region to the base location of the component receiving member at the dome zenith.

DETAILED DESCRIPTION

[0031] The Figures show various embodiments of the base portion 100 and attachment elements 300 which together form the basic configuration of a component holder.

[0032] The features of FIGS. 3 to 7 are functionally identical, but are shown structurally as different variants and perspectives. In order to avoid repetition, reference will be made only to the relevant differences.

[0033] FIG. 1 shows a base portion 100 having a shell-like base structure. In the embodiment shown, the shell 150 comprises a planar base 160 and a cylindrical side wall 170. The base 160 has a (in this instance, stepped) receiving opening 140 for an adapter ring 600. The upper edge 110 of the shell 150 or the base portion 100 is in this instance shown with four retention elements 120, 120, . . . and locking elements 130, 130, . . . in each case. They are arranged in each case in pairs one behind the other on the circumference and form a first portion of four locking units of a bayonet closure. The retention elements 120, 120, . . . are illustrated as radially outwardly protruding journals. The locking elements 130 are shown as rectangular incisions in the upper closure edge 110 of the side wall 170. The cooperation with an attachment element 300 is explained in greater detail below.

[0034] FIG. 2 shows an adapter ring 600 for inserting in the receiving opening 140 of a base portion 100. It is illustrated with a stepped portion 610 which enables a precise centering and improved load distribution in a receiving opening, as shown in FIG. 1.

[0035] FIG. 3 shows the first embodiment of an attachment element in a view obliquely from above. From the top to the bottom, the component receiving member 500 which is in the form of a short mandrel with three annular locking elements 510 can be seen. The component receiving member merges into the zenith of the dome which is formed in this instance from four frames 400, 400 to 400. The shape of the dome is in this instance set out as quite a flat hood. The frames 400 to 400 open in a common edge region 310 which forms the lower closure of the attachment element 300. The upper edge of the edge region is configured in a complex manner and provides various stop faces which act in this instance as retention elements 330. Locking tongues perform the function of the locking elements 320 . . . 320.

[0036] The locking tongues and stop faces are the functional partners of the protruding journals (retention elements 120) and incisions (locking element 120) in the base portion 100 according to FIG. 1.

[0037] The thick arrow in FIGS. 3 and 4 describes the movement sequence of the joining of the attachment element 300 and base portion 100. It can be better understood with reference to FIG. 4.

[0038] In FIG. 4, only a quarter of an attachment element 300 is shown in a view obliquely from below. The thick arrow helps to understand the cooperation of the retention and locking elements 120, 130, 320, 330 ( . . . ). The lower edge 310 of the attachment element 300 also has as many guiding slots 370 as the associated base portion 100 has retention elements 120 (journals). The guiding slots 370 are in this instance illustrated as radially outwardly facing recesses in the lower edge region 310 of the dome; the width and depth are selected to be slightly larger than the dimensions of the journals (retention elements 120) of the base portion. The orientation of the guiding slots 370 is vertical, with respect to the plane defined by the edge region 310 of the attachment element 300.

[0039] The smallest inner diameter of the edge region 310 is selected to be slightly larger than the diameter of the shell 150 on the upper edge 110 (measured without the journals/retention elements 120, . . . ) so that the attachment element 300 can be pushed onto the base portion in a fitting manner. On the inner side of the dome, a U-shaped groove 390 is formed from a guiding strip 350, in this instance in the form of part of the frame 400, the portion of the frame 400 close to the edge and the upper region of the edge 310. In the installed state, the upper edge 110 of the base portion 100 stops against this groove 390, the groove thus acts as a depth limitation during assembly. In this position, the journal (retention element 120, not shown in FIG. 4) can be pushed by means of a rotational movement further in the direction of the arrow over the edge 310 of the attachment element 300. This upper closure of the edge 310 consequently forms the retention element 320 for the journal (retention element 120 of the base portion 100). At the same time, the locking element 330 which is in the form of a resilient finger slides over the upper edge 110 of the base portion 100 until it can engage in a recess (locking element 130) and consequently fixes the relative position of the attachment element 300 and base portion 110 and prevents an independent release. Depending on the configuration of the attachment element and selection of the locking, the configuration may be carried out in a similar manner or differently. The advantages achieved in the present invention are a tool-free assembly and a self-securing locking. Depending on the task, it can be produced as a releasable or non-releasable locking. The preferred method in this instance is a bayonet closure with the described elements.

[0040] In FIG. 3, the locking element 330 is provided with a small semi-circular flap. This enables this locking to be released by means of lifting.

[0041] FIG. 5 shows an attachment element the dome of which takes on the shape of FIGS. 3 and 4 but has a different component receiving member 500. The mandrel is configured to be slimmer and the base location 350 thereof merges in a cup-like manner into the zenith of the dome. The locking elements on the mandrel are configured to be flatter. This embodiment is recommended in particular with a slightly more resilient mandrel/component receiving manner 500 since the cup base improves the introduction of forces into the dome. The locking elements and frame arrangement correspond to FIGS. 3 and 4 as does the functionality.

[0042] FIG. 6 shows an attachment element 300 with a more powerfully curved dome 340 than FIGS. 3-5. The frames 400, 400, etc., have a shape which is reminiscent of an S-shaped curve and merge at the base location 355 of the component receiving member 500. In this Figure, the face 360 which describes the areas between two adjacent frames 400, 400 and the lower edge 310 was also schematically marked. The area is curved in a similar manner to the S-shape of the frames 400 with a rounded tip close to the base location 355.

[0043] In FIG. 7, the area 360 is more powerfully compressed as a result of the flatter dome of the attachment element 300 (similar to FIG. 5).

[0044] For the person skilled in the art, in a manner encouraged by the Figures and the description, other equivalent embodiments are derived, in particular during the configuration of the dome. These are also included in principle by the described principle.
