Additional means may be provided for resisting pivotal movement of the fore part with relation to the heel part under the influence of blows or pressure upon the fore part, and to this end thesole member 12 of the fore part may be provided with a projection 30 which enters a socket 31 in the portion 82 of the front wall of the heel part below the point at which the fore part is hinged or pivoted to the heel part.

The projection 30 may be made in theform of a curved plate or vbar which is inserted into a curved slot 3 made in the non-metal he member 12 of the fore part, said plate and 4 slot being substantially concentric with the a he ar tim hinge pin 17.

In the construction shown in Fig. 5, the fore part b is composed of one piece of non metallic material, such as wood, is pivoted at -lT to the heel part a, and has its upper surface curved downwardly toward the pivot pin 17 and is provided with a substantially vertical rear wall 25, which engages the substantially vertical frontwall 20 of the heel part.

The insert member 28 is pivotally secured to the heel part by the hinge 43 and its front end is locked to the fore partby the pin 44,

which is removed when it is desired to collapse the last. 1 Q

When the insert member is locked to the fore part by the pin 44, the substantially vertical rear wall of the insert member co-operates with the substantially vertical front wall 20 of the heel part to cause the insert member to function as a strutand'resist pivotal movement of the fore part under pressure or blows,

The insert member 23 is shown as pivoted to the heel member but it is not desired to limit the invention in this respect as it is evidentitcan be hinged to the forepart.
