Improvements in or relating to seats

5 This invention relates to seats and more particularly to portable seats for use by sportsmen.

The invention has among its objects to provide a form of seat that is small enough to fit into a rucksack or the pocket of a sports 10 jacket or be carried attached around the waist, thereby leaving the sportsman's arms free, and that can be easily and quickly attached to a vertical support such as a fence post, tree or telegraph pole.

15 According to the invention, there is provided a seat comprising a seat member carried by a supporting plate adapted to engage the surface of a vertical support and means for attaching said supporting plate to said 20 vertical support, said supporting plate being provided with means for making positive engagement with said vertical support when pressed into contact therewith.

By positive engagement as used herein, is 25 meant that the supporting plate is more than simply pressed against the vertical support. Rather it is provided with means that dig into said support. Thus, according to a preferred embodiment, the supporting plate is provided 30 with a wedge-shaped lip at its lower end which will be forced into the vertical support when pressure is applied to the seat. According to another embodiment, the supporting plate is provided with protruding nibbs or 35 teeth to achieve the same result.

According to a further feature of the invention, the seat member may be pivotally attached to the supporting plate so that it may be folded against said plate when not in use. 40 The means for attaching the supporting plate to the vertical support may conveniently consist of a strap or belt which is engaged with the supporting plate which may be formed with slots through which the strap or 45 belt is passed.

According to yet another feature of the invention, the configuration of the supporting plate is such that it is able to engage vertical supports of different diameters. Thus, accord-50 ing to one embodiment, the supporting plate comprises a part circular portion for engaging a vertical support of circular cross-section and outwardly curved portions at the edges of said part circular portion for engaging vertical sup-55 ports of larger diameter.

The invention will now be described by way of example with reference to the accompanying drawings, wherein:

Figure 7 is a plan view of the seat, 60 Figure 2 is a corresponding side elevation, and

Figure 3 is a corresponding front elevation.

As shown, the seat comprises a seat member 10 carried by a frame 11 which is pro-65 vided with hinge members 12.

The seat is pivotally supported on a supporting plate 13 by the engagement of said hinge members 12 with a hinge member 14 on the supporting plate 13, the respective 70 hinge members being mounted on a hinge pin 15.

The supporting plate 12 has a part circular portion 16 and with outwardly curved portions 17 at the edges of the circular portion 75 16. The plate 13 is formed with a pair of slots 18 at its upper end through which is passed a belt or strap 19 for attaching the seat to a vertical support. At its lower end, the plate 13 is formed with a wedge shaped projection 20. 80 When not in use, the seat member 10 is folded into position against the supporting plate 13 so that the seat may be carried in a rucksack or a large pocket or attached around the waist by means of the belt 19. To use the 85 seat, the seat member 10 is pivoted into a position at right angles to the supporting plate 13 which is attached to a vertical support by means of the belt 19. Pressure on the seat member 10 forces the wedge-shaped projec-90 tion 20 into biting engagement with the vertical support whereby the seat is firmly and positively located in position. The provision of the curved portions 16 and 17 on the supporting plate 13 enables the seat to be at-95 tached to vertical supports of different diameters.

The seat frame and the supporting plate may be made from an alloy investment casting, from steel or both. If made from steel,

100 the seat member will be of wood or plastic while if made from an alloy investment casting, the seat member will be cast integrally.

Claims (9)

105 1. A seat comprising a seat member carried by a supporting plate adapted to engage the surface of a vertical support and means for attaching said supporting plate to said vertical support, said supporting plate being
