Auxiliary carrying device

An auxiliary carrying device for carrying an object includes a strap, a handle, and a lacing assembly. The strap surrounds the object and includes a fixing end and a free end. The free end defines a number of through holes along the length thereof. Two ends of the handle are connected to the strap. The lacing assembly includes a connecting element and an adjusting element. The connecting element is fixed to the fixing end. The adjusting element is connected to the connecting element and comprises a post. The post is capable of inserting one of the through holes to connect the free end with the connecting element.

BACKGROUND

1. Technical Field

The present disclosure relates to an auxiliary carrying device.

2. Description of Related Art

It is difficult and inconvenient to carry large, heavy fluid canisters, since a proper grip on the outer surface of the fluid canister is required.

Therefore, it is desirable to provide an auxiliary carrying device that can overcome the described limitations.

DETAILED DESCRIPTION

Referring toFIGS. 1-2, an auxiliary carrying device100, according to an exemplary embodiment, is configured for an object200such as a fluid canister. The auxiliary carrying device100includes a strap10, a handle30, a lacing assembly50, and a fixing assembly80.

The strap10includes a fixing section110and an adjusting section160. The fixing section110is made of flexible material, surrounding and tightly grasping the outer periphery of the object200. The fixing section110includes a first connecting end111and a fixed end113. The adjusting section160includes a second connecting end161and a free end162. The first connecting end111is securely connected to the second connecting end161. The adjusting section160defines a number of first through holes163along the length thereof. A surface of the fixing section110contacting the object200forms an anti-skid pattern, here a plurality of micro bumps, to increase the force of friction therebetween. In this embodiment, the adjusting section160is made of metal.

The handle30connects to the strap10and includes a handle chain33, two middle chains34, and two terminal chains35. The two middle chains34respectively connect to two distal ends of the handle chain33. Each of the two terminal chains35connects to an end of the corresponding middle chain34opposite to the handle chain33. One terminal chain35has a first distal end36opposite to the corresponding middle chain34, the other terminal chain35has a second distal end37opposite to the other corresponding middle chain34. The distance between the first distal end36and the second distal end37can be changed to accommodate the object200of different sizes. The first distal end36defines a second through hole360. The second distal end37defines a third through hole370.

The lacing assembly50includes a first connecting element51, an adjusting element53such as a rivet, a compression elastic element55, such as a coil spring, sleeving on the adjusting element53, and a protective cover57, such as a tube, sleeving on the compression elastic element55. The first connecting element51is hollow and cuboid in shape, and includes a first sidewall511, a second sidewall512opposite to the first sidewall511, a third sidewall513connecting the first and second sidewalls511,512, and a fourth sidewall514opposite to the third sidewall513. The first sidewall511defines a fourth through hole515. A protrusion510is positioned on the second sidewall512and defines a fifth through hole516corresponding to the fourth through hole515. The third sidewall513defines a first through slot517. The fourth sidewall514defines a second through slot518corresponding to the first through slot518. A rod519is formed within the second through slot518, and extends along the height direction of the second through slot518. In this embodiment, the fixing end113of the fixing section110forms a fixing ring114sleeving on the rod519, and thus the fixing end113is fixedly connected with the rod519. The free end162passes through the first slot517and can be protruded through the second through slot518.

The adjusting element53includes a post531, a cap532fixed to an end of the post531, and a baffle ring533sleeving and fixed to the post531.

The fixing assembly80attaches the second distal end37of the handle30to the strap10, and includes a second connecting element81and a fixing element82such as a bolt. The second connecting element81is a hollow cuboid and includes two opposite fifth sidewalls811and a sixth sidewall812connecting the two fifth sidewalls811. Each fifth sidewall811defines a third through slot813, through each of which the fixing section110passes. The sixth sidewall812defines a sixth through hole816(seeFIG. 1).

Also referring toFIGS. 3 through 5, in assembly, the fixing element82passes through the third through hole370and is fixed in the sixth through hole816, and thus the second distal end37is fixed on the fixing assembly80. The fixing section110passes through the two third though slot813, and then the free end162is pulled through the first through slot517and the second through slot518sequentially and toward the fixing ring114until the strap10tightly wraps around the object200and one of the first through hole163is aligned with the fourth through hole515and the fifth through hole516. The second through hole360accommodates the protrusion510. The post531passes through the fourth through hole515, the compression elastic element55sleeves on the post531, and the baffle ring533sleeves over and are fixed on the post531such that the compression elastic element55is resisted by the baffle ring533and the first sidewall511. The protective cover57sleeves over the baffle ring533and the compression elastic element55.

The post531passes through a corresponding first through hole163, the second through hole360, and is received in the fifth through hole516. The compression elastic element55is compressed between the first sidewall511and the baffle ring533, and provides elastictity to the baffle ring533, such that the post531is received in the fifth through hole516until the cap532is stopped by the first sidewall511. Thus, the first distal end36is connected to the strap10, the free end162is connected to the fixing end113, thereby the strap10tightly wraps around the object200. The effective length of the strap10wrapping on the object200can be adjusted by the post531being selectively received in a suitable first through hole163. The protective cover57prevents the compression elastic element55from hurting the user. In other embodiments, the fixing end113can be fixed on the second sidewall512by other technologies, for example, by additional fasteners.

In other embodiments, the baffle ring533and the compression elastic element55can be omitted, the inner sidewall of the second through hole516defines some third threads, the outer sidewall of the post531defines some fourth threads, and thus the adjusting element53can be fixed to the first connecting element51by the third and fourth threads. The first distal end36and the second distal end37can alternatively be directly fixed to the strap10by other means, such as riveting. The handle30can be made of flexible material. The handle30can be integrally formed with the strap10. The protrusion510can also be omitted, and the fourth through hole516directly defined on the second sidewall512.
