Abstract

The patent of the utility model discloses a supplementary annex of braces for preventing single shoulder bag landing, supplementary annex through wearing on the braces comes supplementary single shoulder bag fixed at the shoulder. The auxiliary accessory consists of a pressure elastic bent plate, two movable crankshaft clamps and a fixed bent plate. When normally bearing the single shoulder bag, the downward gravity pressure of the backpack makes the pressure elastic curved plate bend downwards, thereby pushing two crankshaft clamps fixed on the fixed curved plate to realize the turning to the closing, and further showing the clamping force to the shoulder. The fixation of the rucksack on the shoulder is realized by the clamping force. The auxiliary accessory is simple to wear, stable to fix, free of discomfort to a wearer and free of influence on the wearing attractiveness of the single-shoulder bag.

Description

Anti-sliding auxiliary accessory for single-shoulder bag strap

Technical Field

The utility model relates to a shoulder strap auxiliary accessory for preventing single shoulder bag from sliding down.

Background

The backpack is a necessary article in daily life and has various forms. Wherein the single-shoulder backpack is popular because the backpack is more elegant than other backpacks when being carried. However, the rucksack with one shoulder is easy to slip off because the force point is only on one strap and the shoulders of the person are naturally inclined. Especially, the single-shoulder backpack for male business is more prone to slipping off due to more contents and even heavy objects such as a notebook computer, and is usually prevented by holding the backpack with one hand, so that inconvenience is caused.

At present, various anti-slip practical patents are published for the problem that the single-shoulder bag is easy to slip. However, these inventions have very limited actual anti-skid capability, and some have been provided with a binding accessory, which, although the anti-skid effect is good, needs to bind the upper arm or chest of the user, seriously changes the flatness of the clothes on the upper arm or chest of the user, and is very unattractive. The utility model helps the user to prevent the single shoulder bag from slipping off, and the influence on the flatness of shoulder clothes is not more serious than that of a pure brace, thereby ensuring the elegant posture of the single shoulder bag. In addition, in use, extra binding action is not needed, the shoulder bag can automatically clamp the shoulder to prevent slipping as common single-shoulder bags are used, and the use is still very simple and convenient.

Disclosure of Invention

The utility model aims to solve the problem that when carrying heavier articles, the backpack needs one hand to hold the straps constantly to prevent slipping. And through the utility model discloses can effectively liberate both hands, and needn't worry the knapsack landing.

The utility model discloses the technical scheme who adopts when solving above problem is: an auxiliary accessory which clamps the shoulders by means of gravity is worn on the single-shoulder harness. The auxiliary accessory consists of a pressure elastic bent plate, two movable crankshaft clamps and a fixed bent plate; the pressure elastic bent plate and the fixed bent plate are mutually independent and are connected by a middle crankshaft clamp through a hinge. The method is characterized in that:

the whole device consists of three parts, namely a pressure elastic bent plate, two movable crankshaft clamps and a fixed bent plate. The pressure elastic bent plate and the fixed bent plate are spaced apart from each other so that the pressure elastic bent plate has a space for downward deformation to facilitate relative displacement.

Two crankshaft clamps which are movable in the middle are connected with the pressure elastic bent plate and the fixed bent plate through hinges and can deflect at an angle relative to the two bent plates, so that the clamping state and the loosening state are changed. The clamping state of the clamp is in direct proportion to the weight of the carried heavy object.

The upper part of the pressure elastic bent plate is provided with a buckle through which the common back strap passes so as to firmly fix the auxiliary accessories on the back strap. Meanwhile, the straps can slide back and forth through the buckles, so that the angle of the backpack is adjusted, and the comfort level is guaranteed. If the auxiliary accessories are not needed, the auxiliary accessories can be detached.

Drawings

Fig. 1 is a view for explaining the structure of an auxiliary attachment. The upper drawing is a front side view, and the lower drawing is an oblique side view.

With reference to the attached drawings: the pressure elastic bent plate comprises a pressure elastic bent plate 1, a crankshaft clamp 2, a fixed bent plate 3 and a ring buckle 4.

Fig. 2 is a schematic diagram of the operation of the auxiliary attachment. The upper diagram is the natural state of the auxiliary accessories without stress, the middle diagram is the shoulder and back compression state caused by the pressure of the shoulder belt in use, and the lower diagram is the superposition of the two diagrams, which highlights the comparison before and after deformation.

Fig. 3 is a three-dimensional view of an auxiliary accessory.

Detailed Description

The invention will be further explained with reference to fig. 1 (description of the structure of the auxiliary accessories) and the working principle diagram of fig. 2.

Referring to fig. 1, there is shown a shoulder strap accessory for preventing a rucksack from slipping down, in accordance with the present invention. The clasp 4 provides a location for the single shoulder harness to be secured to the accessory. The pressure elastic bent plate 1 and the fixed bent plate 3 both have a certain curvature and are adapted to the shoulder curvature of a wearer. The two bent plates are mutually independent and are connected by a middle bent shaft clamp 2 through a hinge. The straight connecting rod part of the crankshaft clamp 2 and the arc clamp form an angle of 90 degrees. The two curved edges can generate relative angle transformation with the crankshaft clamp 2.

Referring to fig. 2, the structural changes before and after the auxiliary attachment is loaded are shown. The top view shows the natural state of the structures before loading. The middle diagram shows the stress condition and deformation condition of the pressure elastic bent plate 1 and the fixed bent plate 3 when loading. The lower figure shows that the curved surface pad at the head of the crankshaft clamp 2 has larger relative displacement under the stress condition, and a conversion process of changing from loose (dark color part) to tight (light color part) is formed, so that the function of skid resistance is achieved.

The above-described embodiments of the present invention are only one of the preferred embodiments of the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the principle of the present invention should be included in the scope of the present invention.
