Description

Adaptive adjustment belt and backpack that comprises said belt.

The present invention relates to a belt, which can adjust its position according to the body shape of the person carrying it, and a backpack that incorporates said belt.

Backpacks usually comprise a body of bag and a pair of shoulder straps. For transport be more comfortable and safe, some types of backpacks, such as backpacks or backpackers' backpacks, may also include a belt, which stabilizes the bag body, brings it closer to the back of the user and allows to apply part of the body weight of bag not only on the user's shoulders but also on his waist And his hips.

Currently, backpacks comprise generally some means that allow the backpack to be adjusted to Users of different sizes. So, although the bag body It has a fixed size, shoulder straps and belt Their length and position may vary.

Thus, manipulating only a few buckles and straps, the same backpack can fit users with bodies of different characteristics, such as shoulder width, chest and shoulder size, waist size, Torso height and waist shape.

Among the different adjustable features of the backpack - angular adjustment and length of the straps for shoulders, belt length, distance between the belt hip and the upper union of the shoulder straps with the bag body-, one of the most important is the angular position of the hip belt.

A conventional belt is provided with a band that presents a way to better adhere to the profile of the user waist. In fact, to comfortably transport a backpack, the belt should be tightened around the torso just by below the waistline and you must adjust your inclination lateral according to the shape of the user's hips and specifically according to the inclination of the waist below the line of the waist.

Thus, the transport will be comfortable if the force of the weight is applied to a small area of the hip bone in addition of applying to the shoulder, but also if applied uniformly to whole waist line

In order to achieve this goal, they have released some types of belts that may vary not only the distance from the upper union of the straps to shoulders with the bag body but also its position angular.

For example, in the document US-A-5,725,139 discloses a belt whose angular position can be changed; in particular, This type of belt comprises two side parts for hips, each of which has two spaced straps horizontal, one of which can vary in length by adjusting the buckle through which the tape passes. In this way, the two Straps can have different lengths, so the position Angular side part for hips varies.

Thus, when the user puts on the backpack and you have to adjust the belt, you must adjust the buckle and the strap related so that each part for the hips moves angularly to fit the shape of the waist.

These adjustment operations can be repeated until the belt adopts the proper position. It is evident that this adjustment procedure can be complicated and slow, since the adjustment means are also in difficult positions access, so users often do not adjust the belt angularly and, consequently, the weight of the backpack is applied only in small areas of the hip bone, with which the use of The backpack is uncomfortable.

Therefore, the main objective of the invention is to provide a backpack with a belt that can be adjust to each type of user waist shape simply tying it around the torso, without adjustment elements complicated

This and other objectives are achieved with a backpack comprising a bag body and a belt with two side parts for hips, each of which is attached to the bag body at one end, and a belt connection that interconnects said two side parts for hips, in order to surround the user's torso, characterized in that it also includes, for each said part for hips, a strap attached to the part lateral hip related at least one point, forming a closed loop, a first buckle through which said webbing is connected to said bag body and a second buckle to through which said webbing is connected to said connection of belt.

The characteristics and advantages of the invention will be more clearly appreciated from the description following some embodiments illustrated as examples non-limiting in the attached drawings, in which:

Figure 1 is a side view of a part side for belt hip according to the present invention in a first of the many angular positions;

Figure 9 is a side view of a part side for belt hip according to a third form of belt realization.

Referring to the mentioned figures previously, a belt 10 comprises:

-

a right side and left 11, 17 for hip of a padded material joined by 15, 29 to a bag body 30, which only partially shown in figures 4 and 5,

-

a belt connection, usually indicated by reference numerical 18, composed of two bands 19, 21 joined by a closure male-female 31 at its free ends and fixed to the hip parts 11, 17 through respective buckles 16, 23, and

-

two straps 20, each sewn to the hip part 11, 17 related and that pass through a first buckle 14 that designates as a simple buckle in the following description and the second buckle 16.

Since the belt 10 is construction symmetric, now only the right side part of this with particular reference to figures 1 to 3.

The hip part 11 has a shape essentially triangular, a leg C of which is substantially parallel to the maximum extension direction of the backpack, almost vertical.

The junction between the hip part 11 and the body of bag 30 is limited to a small connection part 15 of said triangular shape, specifically at the lower end of said leg C, so that the entire hip side 11 it can rotate around said connection part 15.

The webbing 20 is sewn through its ends to the related hip part 11 at points 25, 27 so that the webbing 20 and the part of the hip part comprised between said points 25, 27 form a closed loop. In particular, said fastening points 25, 27 are located near the other two vertices of the hip part 11.

In addition, the length of said webbing 20 is greater than the direct distance (D) between the attachment points 25, 27 on which the ends of the webbing are sewn, as schematically shown in figure 2; in fact, cinch 20 is retained on the side for hip 11 by the buckle single 14 and the buckle 16 through which the webbing 20 slides.

In this way, the webbing 20 can be divided, ideally, in three parts: the first 24 extends from a fastening point 25 to buckle 16 and has a length L_ {1}, the second part 22 extends from said buckle simple 14 to said buckle 16 and has a length L 3 and the third part 26 extends from the simple buckle 14 to the opposite suture point 27 and has a length L2. So, The total length of the webbing (L_ {+} + L_ {2} + L_ {3}) is greater than the direct distance (D) between the clamping points 25, 27.

A tape 32, which connects said webbing 20 with the bag body 30, passes through the simple buckle 14. Alternatively, said simple buckle 14 may be connected directly to the bag body 30.

Buckle 16 is crossed by one of the two bands 19, 21 that are part of the belt connection 18. Of this mode, each side part for hip 11, 17 is connected by said webbing 20 to bag body 30 and belt connection 18, of so that the belt 10 surrounds the user's torso.

According to a feature of the invention, a sleeve 28 through which cinch 20 passes - specifically the part center 22 of the webbing-, is attached to the top of the hip part 11.

The web 20 moves slidably to through said simple buckle 14 and said buckle 16 so that the lengths (L_ {1} and L_ {3}) of its first and third part 24, 26 may vary. Consequently, when going through sleeve 28, the webbing 20 moves the side parts for hip 11, 17 angularly around the connection part 15.

Thus, as shown in Figures 1 and 3, the side part for hip 11 can be adjusted in angular positions  different, varying the ideal angle having as vertex the part of connection 15 of the side part for hip 11 with the body of bag 30 and as sides the base leg of the ideal triangle to which the side part for hip can be assimilated and the horizontal line ideal from said connecting part 15.

According to figures 4 to 7, when the user wears the backpack, after closing the male-female closure 31 and after having tightened the two bands 19, 21, the defined angles previously they change; in fact, by tightening the two bands 19, 21, the length of the belt 10 decreases and the hip part 11 is consequently moves towards the direction F - the length L_ {2} of the first cinch part 24 increases, while the length L_ {1} of the third part of web 26 decreases. Thanks to this movement, both parts for hip 11, 17 are placed in a higher position, which generates an angle A_ {1}, as shown in figure 1.

Conveniently, this in turn increases the lateral inclination B_ {1} of the hip belt - the inclination from the ideal tangential line to the side profile of the belt- and this Shift allows the hip strap to fit in profiles of prominent hip, as shown in figures 4 and 6.

And, vice versa, if the two bands 19, 21 are extend, the length of the belt 10 increases and the webbing 20 is displaces in relation to the hip part 11; the length L_ {2} of the first part 24 of the webbing decreases while the length L 1 of the third part 26 of the webbing increases.

Thanks to this movement of the webbing, the hip parts 11, 17 are placed in a lower position, which which generates an angle of width less than A 2, as shown in Figure 3

As a result, the lateral inclination of the hip strap decreases-angle B_ {2} - to fit a less prominent hip profile, as illustrated in figures 5 and 7.

As a second preferred embodiment, the webbing 20 can be a band attached to the hip part related at a single point 12, so that it forms a loop closed of a body, as shown in figure 8, in which they use the same numerical references to designate the same parts of the first embodiment.

According to an alternative embodiment shown in figure 9, each side hip part 11 is provided with an opening 13 at the level of the hip bone of user, in order to improve the portability of the backpack.

It is understood that they can be conceived as possible variations, mechanically and / or conceptually equivalent to what is described above, within the scope of the invention.

For example, only one section of the loop closed formed by the webbing 20 can be slidably accommodated  in the part for hip 11, being able to be the other section freely positioned outside it.
