Description

Weight carrying belt capable of moving and rotating negative back pressure

Technical Field

The present invention relates to a weight harness, and more particularly to a weight harness adjustable by a belt carrying manner to allow the back pressure to be moved.

Background

In daily life, people must carry some articles for a long time when using them, although the time for actually sending the articles to the field is not long. A camera is an example. When a user carries a camera to prepare to take a beautiful scene at any time, the user mostly observes a shot object and waits for an optimal image to appear. The camera is quite heavy and tends to be exhausted from the muscles when being held in the hand all the time. Therefore, the camera is usually hung on the neck by a camera strap and is taken up for use when necessary. However, the weight of the camera does not disappear, and the neck is sore even if the neck is pressed for a long time. For this reason, the workshop is also provided with improved camera straps, and the carrying position is adjusted from the neck to the shoulders. Although the backpack camera strap can evenly distribute the weight of the camera to two shoulders, the backpack camera strap has a complex structure and is inconvenient to put on and take off. In addition, the weight of the camera on the shoulders for a long time can press the muscles of the part, which causes discomfort. The camera strap is preferably capable of adjusting the position of the camera strap for applying pressure to the human body at any time, and when discomfort caused by compression occurs, the pressed part of the human body can be quickly transferred, so that the above problems can be resolved.

On the other hand, some instruments require long time carrying on their back in addition to the camera, such as saxophone or french. Although these brass instruments are held by both hands during playing, part of the weight of the instrument is supported by other parts of the body because of the heavy weight and the hands that operate the instrument. The same idea is that these brass instruments require assistance from the instrument harness. It can be appreciated that discomfort problems due to instrument compression can still occur on the instrument harness. The back strap of the musical instrument also has the design of neck load type and double-shoulder back-pack type, and the products between the workshops can not be harmonized with the problems of the neck load type and the double-shoulder back-pack type.

Through the analysis, it can shift and bear pressure to a novel heavy object braces of attitude, makes the user can bear the heavy object for a long time and can not cause muscle fatigue or ache, is that the commodity market needs urgently.

Detailed Description

The technical solution in the embodiment of the present invention is clearly and completely described below with reference to the drawings in the embodiment of the present invention. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be implemented in other ways different from the specific details set forth herein, and one skilled in the art may similarly generalize the present invention without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.

Referring to fig. 1 to 3, fig. 1 is a schematic diagram of an external appearance of a weight carrying strap 1 capable of moving back negative pressure according to an embodiment of the present invention, fig. 2 is a schematic diagram of a left connecting section 12 of a pressure distribution body 10 of the weight carrying strap 1 capable of moving back negative pressure, and fig. 3 is a schematic diagram of an opening of the left connecting section 12. The weight harness 1 capable of moving back negative pressure is composed of the pressure distribution body 10, two connecting belts (a left connecting belt 20 and a right connecting belt 30) and two connecting pieces (a left connecting piece 40 and a right connecting piece 50). The type, material, and function of the above components and the operation of the weight harness 1 capable of moving back negative pressure will be described below.

The pressure-distributing body 10 is of flat construction made of a flexible tensile material. The flexible tensile material may be, but is not limited to, a cotton fabric, a chemical fiber elastic fabric, or a leather fabric, in this embodiment, nylon is taken as an example, which belongs to a chemical fiber elastic fabric and has a good tensile property. In terms of structure, the pressure distribution body 10 has a central section 11 and a left connecting section 12 and a right connecting section 13 on both sides of the central section 11, which are designed to be plane-line symmetric, as viewed from above. An angle α may be formed between the extending direction of the central segment 11 (as indicated by the dotted line in fig. 1) and the extending direction of the left connecting segment 12 (as indicated by the long dashed line in fig. 1), or between the extending direction of the central segment 11 and the extending direction of the right connecting segment 13 (as indicated by the short dashed line in fig. 1), so that the pressure distribution body 10 may have a direction change. In practice, the angle α is between 0 and 30 degrees. If the angle α is 0 degrees, the pressure distribution body 10 is a long straight strip structure. The included angle alpha is 20 degrees in this embodiment. According to the present invention, the left combining section 12 and the right combining section 13 can also be arc-shaped.

The ends of the left combining section 12 and the right combining section 13 form a deviation clamping structure 100, which is the main technical feature of the present invention. Referring to fig. 2 and 3, since the pressure distribution body 10 is designed to be plane-line symmetric, the biased clamping structure 100 of the left connecting segment 12 is taken as an example for illustration. The deflection clamp structure 100 is formed by a bottom clamp 101 and a side clamp 102. The bottom layer 101 is connected to the face layer 102 on a closed side 103, so that the biased sandwich structure 100 can be open towards the direction of extension of the left joining section 12 and towards an active side 104. The maximum open state of the biased clip structure 100 is shown in fig. 3, and is formed by inclining at an angle along the extending direction of the left connecting section 12. A first movable ring 105 is sewn into the bottom sandwich layer 101 and the face sandwich layer 102 of the deflection sandwich structure 100, and the function of the first movable ring 105 will be described in conjunction with other components. It is noted that, according to the present invention, the first movable ring 105 should be a circular ring or a D-shaped ring, and the best use effect is achieved by the circular portion of the circular ring or the D-shaped ring. The first movable ring 105 is hidden when the bottom sandwich 101 is flush with the face sandwich 102 and is visible when biased open towards the sandwich structure 100. In addition, a strap length adjuster 106 is sewn to the edge of the biasing clip structure 100, preferably on the inside of the facing layer 102. The belt length adjuster 106 functions to adjust the length of both sides spanned by the connecting belt (here, the left connecting belt 20) inserted therethrough. In practice, the strap length adjuster 106 may use a turnbuckle. It is noted that the movable sides 104 of the biased sandwiching structure 100 of the left and right combining sections 12 and 13 are located on the same side of the pressure distribution body 10, and are designed for switching the use mode.

Both the left and right connecting bands 20, 30 are identical in function, structure, material, and even length. For convenience of illustration, the left connecting band 20 is illustrated in fig. 2 and 3. A first end 201 of the left connecting strap 20 slidably connects one of the two first movable rings 105 (the first movable ring 105 of the biased sandwiching structure 100 of the left coupling segment 12). Because flexible sliding is desired, first movable ring 105 is preferably a circular ring or a D-ring, but not a square ring or a triangular ring having straight corners, because first end 201 of left connecting strap 20 can slide on first movable ring 105 toward movable side 104, and if a square ring or a triangular ring is used, the corners can limit the movement of left connecting strap 20. A second end 202 of the left connecting strap 20 is sewed with a second movable ring 203. The portion of the left connecting band 20 between the first end 201 and the second end 202 passes through the band length adjuster 106, so that the length of a first adjustable section 204 of the left connecting band 20 between the band length adjuster 106 and the second end 202 can be adjusted. The length of left connecting strap 20 not including first adjustable section 204 is a second adjustable section 205 (between first end 201 and strap length adjuster 106, forming a flexible loop with biasing clip structure 100). As the length of the first adjustable section 204 becomes longer, the overall length of the second adjustable section 205 is shortened, and vice versa. Thus, when the length of the first adjustable section 204 is adjusted, the object actually adjusted is the second adjustable section 205. Since the second adjustable section 205 is too long, only the portion of the second adjustable section near the first end 201 and the band length adjuster 106 is shown in fig. 2 and 3, and the rest is omitted. To facilitate adjusting the length of the first adjustable section 204, the user can grip and pull the second movable ring 203 with force, at which time the length of the first adjustable section 204 is increased and the length of the second adjustable section 205 is decreased. To adjust in the reverse direction, the strap length adjuster 106 is loosened and force is applied to the second adjustable section 205 to brace it laterally outward. Thus, the second movable ring 203 may be any shape of ring including, but not limited to, a circular ring, a D-shaped ring, a square ring, and a triangular ring. In terms of materials, the left connecting band 20 and the right connecting band 30 may be made of cotton cloth, chemical fiber elastic cloth, or leather, as in the pressure distribution body 10. In this embodiment, nylon is also used as an example.

The left connecting member 40 and the right connecting member 50 are used to directly or indirectly connect a carrying object, and each connecting member is movably inserted into the second adjustable section 205 of one of the two connecting bands (i.e. inserted into the flexible ring). In the present embodiment, the left connecting member 40 and the right connecting member 50 are connecting fasteners, and can be indirectly coupled to the bottom of a camera 80 (as shown in fig. 4 to 6) through a camera quick-release plate 60. In other embodiments, the left and right connectors 40 and 50 may be a hook or a string that is connected to a docking object of another carrying object (e.g., a saxophone).

According to the present invention, the weight harness 1 with movable negative back pressure can further comprise 2 tie clips 70. Each attachment belt clip 70 may be used to clip the first adjustable section 204 of the two attachment belts to the second adjustable section 205, preventing the first adjustable section 204 from being too long and wobbling during use.

In addition, according to the present invention, the weight harness 1 capable of moving back negative pressure further comprises an elastic layer 10 'inside the pressure distribution body 10 (the elastic layer 10' is covered in the pressure distribution body 10 and cannot be seen from the outside, so it is depicted by a dotted frame in fig. 1). In the present embodiment, the material of the elastic interlayer 10' is Expanded Polyethylene (EPE); in practice, Ethylene-vinyl acetate (EVA) may be used instead. The function of the elastic sandwich layer 10' is to increase the elasticity of the pressure distribution body 10, so that the weight of the carried object can be dynamically distributed to the human body contact part. Thus, other perforated hollow permeable materials may be used for the elastic interlayer 10'.

Fig. 4 shows a use of the weight harness 1 with a movable negative back pressure. In this usage aspect, the pressure distribution body 10 transfers the weight of the carried object (camera 80) to the neck of the user 90 through the left and right connecting bands 20 and 30 and the pressure distribution body 10 in such a way that the central section 11 contacts the back neck of the user 90 (shown by dotted lines because it cannot be seen from the front), and part of the left and right connecting sections 12 and 13 contact the side neck of the user 90. At this time, the second adjustable segment 205 is folded back at the position of the left connecting member 40 or the right connecting member 50, and two sides of the folded back position are overlapped with each other. This is a conventional neck load strap design, and if the included angle α is provided or the left and right engaging sections 12 and 13 are curved, the pressure distribution body 10 will be more closely attached to the neck of the user 90.

There is another use of the weight harness 1 with the possibility of moving the negative back pressure. Referring to fig. 5 and 6, fig. 5 shows a state of use of the weight harness 1 capable of moving back negative pressure, and fig. 6 shows another state of use of the weight harness 1 capable of moving back negative pressure. In this use aspect, the pressure distribution body 10 transfers the weight of the carried object (camera 80) to the shoulders and upper back of the user 90 in such a way that it contacts the shoulders and upper back (shown in dashed lines since it cannot be seen from the front) of the user 90 from left to right. At this time, the first ends 201 of the left and right connection belts 20 and 30 slide on the first movable ring 105 toward the movable side 104, so that the second adjustable segments 205 form the aforementioned closed rings, and the two arms of the user 90 can pass through each closed ring respectively. If the closed loop is too loose, the second movable loop 203 may be pulled down (in the direction of the arrow in FIG. 6) to reduce the length of the second adjustable section 205; if the closure loop is too tight, the strap length adjuster 106 may be loosened to increase the second adjustable section length 205, thereby adjusting the closure loop size for easy use by the user 90.

The foregoing description is only of the preferred embodiments of the present invention, and it should be understood that the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
