JP2016517761A - Polymorphic backpack - Google Patents

Abstract

The polymorphic backpack comprises a back part (1) comprising a releasable first connecting means (6a) and a pair of shoulder straps (3) having connecting means (4, 7), said back part (1) And the second connecting means (6b) complementary to the first connecting means (6a), respectively, and the connecting means (4, 7) to the shoulder strap (3). It is provided with various flexible bodies (2, 2a, 2b) which are different in shape and form and can be selectively exchanged with each other, with fastening elements (5, 8) for connection.

Description

  The present invention relates to a backpack of the type comprising a body typically made of a flexible material and having a shoulder strap for transport by a user.

  In some known backpacks, including those that have been successfully manufactured and sold by the applicant, the shoulder strap is partially or even completely separated from the body. For example, in the case of European patent application EP-A-2155013, the shoulder strap comprises a quick connection element for connection means corresponding to one or the other of the two opposite types of body which are reversible. The user can select one or the other form of the main body to use the backpack, but the main body forms are basically different from each other only in aesthetic appearance.

  The aim is to allow users to use a wide variety of different backpack configurations that are practical, functional and relatively inexpensive to manufacture.

  According to the present invention, this object is directed to the first connection means for the union of the back part comprising a releasable first connection means and a pair of shoulder straps having coupling means, and the back part. Each having a second connecting means complementary to each other and having a fastening element for connecting the connecting means to the shoulder strap. This is achieved by a polymorphic backpack comprising a body.

  With this solution, the backpack user can maintain the back with shoulder straps without replacement, not only with regard to the appearance or appearance design, but also, for example, differences in internal space compartments, presence or absence of external pockets. For functional elements such as, the body can be easily replaced with one or more different bodies.

  The first connecting means on the back and the second connecting means on the different flexible body can be selected from fasteners, snap fit buckles, hooks, micro hook strips and the like.

  The present invention will be described in more detail with reference to the accompanying drawings, which are non-limiting examples.

1 is a front perspective view showing a first possible form of a polymorphic backpack according to the present invention. FIG. The rear exploded perspective view of FIG. FIG. 3 is a view similar to FIG. 2 illustrating different individual forms of the polymorphic backpack according to the present invention. FIG. 3 is a view similar to FIG. 2 illustrating different individual forms of the polymorphic backpack according to the present invention.

  Referring initially to FIGS. 1 and 2, the backpack according to the present invention basically comprises two elements that are separable from each other, namely the back 1 constituting a single part, and the characteristic aspects of the present invention. According to the present invention, the flexible main body 2 includes various shapes and forms that are different in terms of appearance and / or function, and is a selection function.

  For example, a back 1 made of a flexible or relatively soft seat with a pad comprises a pair of shoulder straps 3 with one end preferably fixed permanently on the top of the back 1. The opposite end portion is provided with connecting means 4 which can be attached to a corresponding ring 5 made of, for example, an elastic snap hook and provided at the lower portion of the flexible main body 2.

  The back part 2 and the flexible main body 2 are a pair of closed fasteners in the illustrated example, and the parts 6 a and 6 b are provided along the side part along the side part of the back part 1, respectively. Are provided on opposite sides of the back wall. The connection method may alternatively comprise snap fasteners, hooks, microhook strips, etc. that engage each other.

  In order to further ensure the connection between the back part 1 and the flexible main body 2, for example, the upper part of the shoulder strap 3 and the male and female fastened snap buckles 7 and 8 provided at the top of the flexible main body 2 are formed. Other releasable coalescing elements may be provided.

  As described above, the back 1 constitutes an integral part of the shoulder strap 3, which can be applied to a number of different flexible bodies that are now available on the market. In terms of appearance and partly in functional form. The example of the flexible body 2 represented in the embodiment of FIGS. 1 and 2 and shown in FIGS. 3 and 4 as 2a and 2b, respectively, can have different external pockets and internal volume distribution. The difference in functional characteristics is clearly shown with respect to the access opening in the flexible body.

  The details of construction and the embodiments can vary widely in what has been described and illustrated without departing from the scope of the invention as defined in the claims.
