Scaffolding

Claim 2

In scaffolding, comprising bracing frames and vertical uprights, said vertical uprights having coupling means enabling said uprights to be fitted one above another, and lateral engaging means for the engagement of said bracing frames, said bracing frames including complementary engaging means adapted to cooperate with said lateral engaging means of adjacent vertical uprights, the improvement wherein each said bracing frame comprises at least one connecting cross member having an end comprising securing means adapted to be secured (at least in a horizontal direction) directly to an adjacent said bracing frame, at least some of said bracing frames comprisiNg two skew connecting cross-members which cooperate with a horizontal crossmember to form a triangle lying between immediately adjacent vertical uprights, said securing means being located at the corner of a triangle where said skew connecting cross-members meet.

Claim 3

The improved scaffolding of claim 1 wherein the securable end of the connecting cross-member is rigidly secured to a horizontal cross-member of the adjacent bracing frame.

Claim 4

The improved scaffolding of claim 2 wherein the bracing frames are disposed securable end downwards.

Claim 5

The improved scaffolding of claim 2 wherein the bracing frames are disposed securable end upwards.

Claim 6

The improved scaffolding of claim 1 wherein the means enabling the vertical uprights to be placed one above another are adapted to lock the system embodied by said lateral engaging means and the complementary engaging means.

Claim 7

The improved scaffolding of claim 5 wherein said lateral engaging means are disposed near the top end of the vertical upright, the means for enabling the vertical uprights to be coupled together one above another being adapted to form an abutment opposing release of the complementary engaging means from said lateral engaging means of the adjacent vertical upright immediately below.

Claim 8

In scaffolding, comprising bracing frames and vertical uprights, said vertical uprights having coupling means enabling said uprights to be fitted one above another, and lateral engaging means for the engagement of said bracing frames, said bracing frames including complementary engaging means adapted to cooperate with said lateral engaging means, the improvement wherein each said bracing frame comprises at least one connecting crossmember having an end comprising securing means adapted to be secured (at least in a horizontal direction) to an adjacent said bracing frame, and telescopic elements adapted to take up a number of extended positions relatively to the vertical upright, characterized in that the telescopic elements have lateral engaging means near their top end, follower frames arranged to brace the telescopic elements against one another, said follower frames having complementary engaging means adapted to cooperate with said lateral engaging means of the telescopic elements, each follower frame having at least one connecting cross-member, having an end securable (at least in horizontal direction) to the bracing frame interconnecting the vertical uprights bearing the telescopic elements, whatever the position thereof and of the follower frame engaged with the telescopic elements.

Claim 9

In scaffolding, comprising bracing frames and vertical uprights, said vertical uprights having coupling means enabling said uprights to be fitted one above another, and lateral engaging means for the engagement of said bracing frames, said bracing frames including complementary engaging means adapted to cooperate with said lateral engaging means, the improvement wherein each said bracing frame comprises at least one connecting crossmember having an end comprising securing means adapted to be secured (at least in a horizontal direction) to an adjacent said bracing frame, and telescopic elements adapted to take up a number of extended positions relatively to the vertical upright, characterized in that the telescopic elements have lateral engaging means near their top end, follower frames arranged to brace the telescopic elements against one another, said follower frames having complementary engaging means adapted to cooperate with said lateral engaging means of the telescopic elements, each follower frame having at least one connecting cross-member, having an end securable (at least in horizontal direction) to the bracing frame interconnecting the vertical uprights bearing the telescopic elements, whatever the position thereof and of the follower frame engaged with the telescopic elements.

Claim 10

The improved scaffolding of claim 7 wherein the follower frame comprises two skew connecting cross-members which cooperate with a horizontal cross-member to form a triangle.

Claim 11

The improved scaffolding of claim 8 wherein the securable ends of the two connecting cross-members are interconnected and are rigidly secured to a vertical cross-member which extends to and is secured to the horizontal cross-member.

Claim 12

The improved scaffolding of claim 9, wherein the vertical cross-member forms the guide means.

Claim 13

The improved scaffolding of claim 10, wherein the bracing frame comprises a vertical cross-member which cooperates telescopically with the vertical cross-member of the follower frame, the guide means being embodied a system of apertures and pins, the apertures being distributed at the same pitch as the apertures for varying the extension of the telescopic elements.

Claim 14

The improved scaffolding of claim 7 wherein the lateral engaging means of the vertical uprights and the lateral engaging means of the telescopic elements are embodied by four members which are disposed at 90* to one another at the same level as one another.
