DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The objects, the technical contents and the expected effectiveness of the present invention will become more apparent from the detailed description of the preferred embodiments in conjunction with the accompanying drawings.

Firstly referring to Figure 1, the backpack having lifesaving function of the present invention comprises a backpack (1), water bags (2) and a sub-backpack (3).

As shown in Figures 1 and 2, the backpack (1) is made of materials capable of floating on water, such as plastic materials, EVA etc... The backpack (1) has many accommodation spaces for receiving various goods, and two shoulder straps (11) are provided on the inner end face thereof; chest straps (12) capable of buckling together are connected between the two shoulder straps (11); and waist straps (13) capable of buckling together are provided at the lower edges on both sides of the inner end faces thereof. When user carries the backpack (1) on his back by the shoulder straps (11), he can allow the backpack (1) to be carried more stably on his back by simultaneously buckling the chest straps (12) at his chest and the waist straps (13) at his waist. In addition, connection straps (14) are also provided on upper, lower, left and right end surfaces of the backpack (1), which can be buckled with connection straps (14) of the other backpack (1).

The water bags (2) are received in the interior of the backpack (1). A closed space for filling with either water or air can be formed in each water bag (2). Further, connection straps (21) corresponding to the connection straps (14) of the backpack (1) are respectively provided on both sides of each water bag (2) in such a manner that the connection straps (14) on both sides of the backpack (1) can be buckled with connection straps (21) of two corresponding water bags (2).

The sub-backpack (3) is similarly provided with several accommodation spaces for receiving various goods. Connection straps (31) corresponding to the connection straps (14) of the backpack (1) are also provided on the sub-backpack (3) so that the sub-backpack (3) can be combined with the backpack (1) by the buckling of the connection straps (31) with the corresponding connection straps (14) of the backpack (1). Hence, loading capacity of goods carried by users can be increased.

The connection straps (14) of the backpack (1) have a male buckle (141) on one side and a matching female buckle (142) on the other side. Two backpacks (1) can be combined together by the buckling of the male buckle (141) and the corresponding female buckle (142). Further referring to Figure 3, the connection straps (14) of the backpack (1) have a strap (143) one side and a cooperating buckle (144) on the other side so that two backpacks (1) can be combined together by penetrating the strap (143) inside the cooperating buckle (144) so as to be fastened in a manner as shown in Figure 4. Figure 5 is a perspective view showing still another embodiment of a backpack of the present invention. As shown in the figure, the connection straps (14) of the backpack (1) have a strap (143) on one side and a cooperating pair of D ring (145) on the other side so that two backpacks (1) can be combined together by penetrating the strap (143) inside the pair of D ring (145) to be fastened in a manner as shown in Figure 6.

Configuring like this, as shown in Figures 7 and 8, after a plurality of backpack (1) lies down in matrix arrangement, each backpack (1) can be combined with neighboring backpacks (1) by the buckling of its upper, lower, left and right connection straps (14) with that of the neighboring backpacks (1) so that the backpacks (1) are formed into a planar connection. In addition, as the backpacks (1) is made of materials capable of floating on water, such as plastic material, EVA etc., the backpacks (1) formed into a planar connection can be floating on water, when it is put on water. Hence, it can be used to carry personnel or goods for crossing river or for emergency relief on water.

Alternatively, the water inside is poured out after the water bag (2) is taken out from the backpack (1), and then the water bag (2) is filled with air. In turn, the backpack (1) is combined with two water bags (2) on both sides by the buckling of its connection straps (14) with the connection straps (21) of the water bags (2). When user carries the backpack (1) on his back by the shoulder straps (11), he can allow the backpack (1) to be carried more stably on his back by simultaneously buckling the chest straps (12) at his chest and the waist straps (13) at his waist. When crossing river, not only the material of the backpack (1) itself can floating on water but also the floating force can further enhanced by the air filled in the water bags (2) connected at both sides of the backpack (1), thus this can facilitate users to cross river.

Referring to Figure 9, a plurality of the backpack (1) of the present invention can be aligned in matrix arrangement to match the width of river, and then the backpacks (1) can be combined together by the buckling of their upper, lower, left and right connection straps (14) with that of the neighboring backpacks (1) so that the backpacks (1) are formed into a planar connection. Further, the connection straps (14) of the outmost backpacks (1) at both ends are tied up with rods (4) spanning between both sides of river. As the backpacks (1) are made of materials capable of floating on water, the backpacks (1), formed into a planar matrix, spanning over the river can float on water to serve as a bridge. When the backpacks (1) spanning over the river is used as a bridge, ropes or the other rods can be provided above the rods (4) spanning between both sides of river to serve as armrests (5), so as to enhance convenience and safety in crossing river.

Aforementioned embodiments and drawings are not to restrict the product structure or implementation modes. Appropriate variations and modifications done by the people having general knowledge in the art without departing from the scope and features of the present invention are considered to be still within the scope of the present invention.

Based on the above description of component constitution and implementation of the present invention, when comparing to the conventional art, not only users can cross rivers safely by means of the backpack structure so as to increase survival possibility in the field, but also it can carry personnel, goods or conduct emergency relief on water. Therefore, it can increase more practical effect and characteristics in its overall implementation.
