SECTIONAL ROW BOAT Oskar A. Miiller, Zurich, Switzerland Application April 1, 1953, Serial No. 346,170

Claims priority, application Germany April 3, 1952 1 Claim. (Cl. 9-2) The present invention relates to sectional row boats.

There are disjoinable row boats known, which are composed of a timber or metal skeleton covered by a watertight textile or rubber cover. These known boats have the disadvantage that their assembling is rather wearisome and their security in use is questionable due to the fact that such thin covers are very easily damaged.

There are further also disjoinable all-metal boats known, which are composed of several sections connected to each other. However, in these known metal boats the sections are not separated from each other by intermediate walls so that the points between the sections must be made tight. Thus, these boats are very complicated in construction, Wearisome in assembling and the parts and sections assembled by packings, screws, connecting cables and folds are easily damaged in use so that these constructions did not prove good.

In other known boats, of the type disjoinable in longitudinal direction and the individual sections of which are provided with watertight closing walls, the separate sections are connected to each other by means such as pins, bolts, plugs, hinges, connecting ropes or cables, or the bow and stern sections cannot be formed as buoyant bodies, or the top cannot be constructed as simply as would be desirable, so that this type of disjoinable boats has also not been successful.

In contradistinction thereto the sectional row boat according to the present invention comprises at least a trough-like seating section formed of sheet metal, which seating section is adapted to be disjoinably connected by means of denticulations with a bow and with a stern section formed as buoyant bodies, whereby the largest boat section is adapted to contain, when the boat is disjoined, all other sections of the boat. The connecting means are similar for all boat sections. Thus there may be two seating sections of difierent dimensions provided, whereby such a double-seater boat is assembled by connecting the two seating sections with each other and securing the bow section to the free end of the smaller seating section and the stern section to the larger seating section. 7

By assembling with two or three suitably dimensioned seating sections a threeor four-seater boat may be provided. All elements necessary for the assembling are preferably fixedly or movably connected with the corresponding sections of the boats in order to prevent loss of such smaller parts. The boat according to the invention does not need any tools or other auxiliary means for its assembling or disjoining.

An embodiment of a sectional row boat according to the invention is represented by way of example, in the accompanying drawings, in which:

Fig. 1 is a plan view of a double-seater boat,

2. Fig. 2 is asectional view alongthe line 2-4 in Fig. 1, Fig. 3 is a plan. view of. the disjoinedboat with the separate sections adaptedin the largest section and the tops removed,

Fig. 4 is a section along the line 4-4 of Fig. 2, and

Fig. 5 is a section corresponding to the one of Fig. 4 but through a variant.

In the drawings the reference numeral 1 designates the smaller front seating section, 2 the rear seating section of larger dimensions, 3 the bow section and 4 the stern section of the boat. All sections are formed of sheet metal. The bow and stern sections are provided with openings not shown which may be tightly closed so that these two sections form air-tight buoyant bodies, while the intermediately disposed seating sections 1 and 2 are trough-shaped. The adjacent walls of the sections 1-4 are provided with recesses 5 and protrusions 6 respectively, adapted to engage each other when the boat is assembled. By this dovetail connection vertical relative displacement of the sections as well as deflection of the keel in longitudinal direction of the boat is prevented. The separate sections of the boat are disconnectably secured to each other by means of tighteners 7 of known construction. In order to protect the seating sections 1 and 2 from incoming water these sections are covered with two cover sheets 8, adapted to engage each with a marginal bent portion 10 a fold 11 formed at the upper rim of the trough-like seating sections 1 and 2 respectively. The cover sheets 8 are thus firmly held in position by means of tighteners 9 similar to the tighteners 7 used for the connection of the sections with each other, thus forming the top of the seating sections 1 and 2. Cutouts in the cover sheets 8 provide, when the boat is assembled, openings 12, 13 for the passengers. If necessary a protection cover may be adapted on the top of the seating sections as is already used in heretofore known canoes. It is understood that the cooperating parts of the tighteners are fixed to the corresponding parts of the boat so that they cannot be lost.

In order to increase'the stability of the boat the separate seating sections may be provided with protruding portions 1a (Fig. 5) disposed below the water line, which portions, when the boat is inclined, cause an increased buoyancy relatively distant from the median line of the boat, which efiect is the same as the one obtained in cantilever boats and moreover prevents the boat from deviation from the straight course.

After the boat has been taken apart by releasing the

tighteners

7, 9 the bow and

stern sections

3, 4 are laid into thesmaller seating section 1, as shown in Fig. 3. The latter fits into the larger seating section "2, whereafter the latter is covered by its two cover sheets 8. Thereby a compact unit for transportation on land of the complete boat is provided, the overall dimensions of said unit being those of the larger seating section 2.

What I claim is:

In a sectional row boat having a plurality of sections longitudinally alined with their adjacent ends joined by abutting walls, in combination: at least one trough-like seating section having a fold provided on its upper lateral rims, two cover sheets having bent-01f edge portions adapted to engage said lateral folds, a first set of tighteners provided on said sheets for firmly connecting said two sheets with their bent-off portions engaged in the folds, a bow and a stern section forming buoyant bodies, protrusions provided on one of the abutting walls and adapted to engage recesses provided on the other of the abutting walls for preventing vertical relative displacement of the sections, a second set'of tighteners secured to said sections for connecting said'sections together, the sections being progressively smaller so that the largest section of the boat may contain all remainder sections of the boat when the latter is taken apart to provide a cornpact unit for transportation purposes.
