Abstract
Abstract A framing system for supporting false ceilings includes a vertically adjustable suspension member carrying a bracket. Means are provided to mount cross members to the bracket by pushing the cross members from below up into coacting locking means formed on the bracket and the cross members and then moving an arm outwardly from the end of the cross member to rest upon a horizontal bearing surface of the bracket to thereby suspend the cross members from the hanger.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
168 words
A structural unit for a frame construction, mounted suspended in rooms and consisting of horizontal cross members, disposed at angles to one another and brought together at connecting points, used to support a false ceiling, comprising a connecting member provided at the two ends of the cross members, with frontal faces perpendicular to the longitudinal direction of the cross members, connecting elements disposed at the points of connection, each with one hanger and a number of connecting flanges, vertical in the suspended state, corresponding to the number of connecting members to be joined together frame-wise, edge guides provided on the faces of the connecting members and forming guides for the insertion of the connecting flange against the respective face and arms provided on each connecting member, movable outwardly beyond the connecting member in the lengthwise direction of the cross member when the respective connecting flange has been pushed into the position of locking with the corresponding connecting element to thereby mount the cross members to the connecting elements.
Claim 2
Dependent Claim
168 words
A structural unit for a frame construction, mounted suspended in rooms and consisting of horizontal cross members, disposed at angles to one another and brought together at connecting points, used to support a false ceiling, comprising a connecting member provided at the two ends of the cross members, with frontal faces perpendicular to the longitudinal direction of the cross members, connecting elements disposed at the points of connection, each with one hanger and a number of connecting flanges, vertical in the suspended state, corresponding to the number of connecting members to be joined together frame-wise, edge guides provided on the faces of the connecting members and forming guides for the insertion of the connecting flange against the respective face and arms provided on each connecting member, movable outwardly beyond the connecting member in the lengthwise direction of the cross member when the respective connecting flange has been pushed into the position of locking with the corresponding connecting element to thereby mount the cross members to the connecting elements.
Claim 3
Dependent Claim
43 words
A structural unit as defined in claim 1, and in which each connecting element has a bearing surface horizontal in the suspended state to support the arms of the attached connecting members and on the periphery of which the connecting flanges are provided.
Claim 4
Dependent Claim
24 words
A structural unit as defined in claim 1 and in which the cross members are open along one lengthwise side, with a U-shaped profile.
Claim 5
Dependent Claim
50 words
A structural unit as defined in claim 2 and in which the connecting flanges extend from the bearing surface away from the hanger and in which each connecting member is provided with the arm on its edge which is parallel to the open side of the U-profile and nearest thereto.
Claim 6
Dependent Claim
25 words
A structural unit as defined in claim 4, and in which the arm is fastened to the connecting member by means of a sliding guide.
Claim 7
Dependent Claim
17 words
A structural unit as defined in claim 1 and in which the hanger is adjustable for length.
Claim 8
Dependent Claim
63 words
A structural unit as defined in claim 6 and in which the hanger is a threaded round rod provided with a loop, and which is mounted in a rotary threaded guide disposed on a supporting bracket the hanger being pivotal at points near the periphery of the bearing surface and being aligned with the center of a central recess in the bearing surface.
Claim 9
Dependent Claim
50 words
A structural unit as defined in claim 3 in which each connecting member, near that edge which is associated with the base of the U-shaped profile, is fashioned with edge guide and detent elements on its frontal surface, cover elements mounted in place by said edge guide and detent elements.
Claim 10
Dependent Claim
45 words
A structural unit as defined in claim 8 said cover elements having sidewalls and in which the distAnce of the edge guide and detent elements from the base of the U-shaped profile corresponds substantially to the height of the respective sidewall of the cover element.
Claim 11
Dependent Claim
40 words
A structural unit as defined in claim 9 and in which the respective sidewall of the cover element has an outer bead along its rim and retaining slots of appropriate dimensions are provided in the faces of the connecting members.
Claim 12
Dependent Claim
34 words
A structural unit as defined in claim 10 and including angle clips on the faces of the connecting members which form an edge support for the rim of the respective sidewall with the face.
Claim 13
Dependent Claim
25 words
A structural unit as defined in claim 1 and in which the cross members are filled with sound-absorbing material and are made of perforated material.
Claim 14
Dependent Claim
47 words
A structural unit as defined in claim 3 and in which the connecting members are not as high as the U-shaped profiles and are fashioned with a bearing surface, disposed at right angles to the legs of the U-shaped profile and extending into the respective cross member.
Claim 15
Dependent Claim
32 words
A structural unit as defined in claim 3 and in which the connecting members are fashioned with mounting surfaces which bear against the inner side of the leg of the U-shaped profile.
Claim 16
Dependent Claim
43 words
A structural unit as defined in claim 3 and in which the cross members are equipped with means of attachment for luminescent bodies at a predetermined point, the same for several cross members on the outside of the legs of the U-shaped profile.
