Abstract
Abstract A formwork table arrangement having a formwork table (13) and a plurality of supports (11) each of which is downwardly pivotably and removably mounted via a transition support member (12), which can be releasably secured to a head end of the respective support, to a counter-support member (14) that is releasably attached to a lower side of the formwork table. Hooks and hook holders (17, 18) are provided at the transition support member (12) and at the counter-support member (14) which permit suspension of the transition support member (12) from the counter-support member (14). A latching arrangement (24, 25, 28) enables the latching of the transition support member (12) to the counter-support member (14) when tilted into the normally upright working position.

Arrangement in accordance with claim 3 wherein the first cheeks include hooks associated with one of the support plates at a bottom portion of the first cheeks, and wherein the second cheeks include hook holders associated with the other one of the support plates.
Claim 7
Dependent Claim
53 words
Arrangement in accordance with claim 2 wherein the engaging arrangement comprises hooks and hook holders at the transition support member and at the counter-support member, wherein the latching system includes a pivotally movable latch, and wherein the latch in its latching position extends about an edge defined by the oppositely disposed support plates.
Claim 8
Dependent Claim
42 words
Arrangement in accordance with claim 2 wherein the engaging arrangement comprises hooks and hook holders at the transition support member and at the counter-support member, and including a holder having a top welded to the support plates of the transition support member.
Claim 9
Dependent Claim
48 words
Arrangement in accordance with claim 2 wherein the engaging arrangement comprises cooperating hooks and hook holders at the transition support member and at the counter-support member; and wherein first and second, spaced-apart hooks are arranged alongside one another at at least one end of the associated support plate.
Claim 10
Dependent Claim
39 words
Arrangement in accordance with claim 8 including further hooks and hook holders provided symmetrically with respect to the hooks and hook holders relative to a substantially horizontal central transverse axis of the transition support member and the counter-support member.
Claim 11
Dependent Claim
26 words
Arrangement in accordance with claim 1 wherein the engaging arrangement comprises cooperating hooks and hook holders at the transition support member and at the counter-support member.
Claim 12
Dependent Claim
32 words
Arrangement in accordance with claim 10 wherein one of the counter-support member and the transition support member includes side cheeks, and wherein the hooks are provided at ends of the side cheeks.
Claim 13
Dependent Claim
35 words
Arrangement in accordance with claim 11 wherein the other one of the counter-support member and the transition support member includes lateral cheeks, and wherein the hook holders are provided at ends of the lateral cheeks.
Claim 14
Dependent Claim
67 words
Arrangement in accordance with claim 10 wherein the transition support member and the counter-support member each have a generally rectangular support plate which extends substantially parallel to the formwork table, and wherein the hook holders are formed by bent brackets formed by one of the support plates which define a space enabling passage of the hooks on the other support plate into engagement with the hook holders.
Claim 15
Dependent Claim
18 words
Arrangement in accordance with claim 13 wherein the other support plate includes cut-outs for receiving the bent brackets.
Claim 16
Dependent Claim
41 words

Claim 17
Dependent Claim
63 words
Arrangement in accordance with claim 1 wherein the latching system includes at least one latching lever which is pivotally connected to one of the support members and carries a latch which, when the support members are engaged with one another, and when the latch lever is in a latching position, acts on the other support member to firmly connect the support members together.
Claim 18
Dependent Claim
