Background

As is well known, a load is a burden on the human body, and there is a demand for reducing the load on the human body by using a mechanism to reduce the fatigue of the human body.

The backpack is a daily product, and a backpack with a weight reduction function is researched and developed abroad, such as a suspension backpack, and the suspension backpack can shake up and down in a reciprocating manner when a human body moves, so that the oppression of the weight on the human body when the backpack is carried can be reduced, and a weight reduction effect is achieved.

For example, the US20060192386a1 provides a suspension pack solution, see fig. 4 thereof, whose weight-reducing mechanism comprises a frame 20, four springs 50, a support plate 40, and a sleeve 60. The frame 20 is stationary relative to the human body. The load 30 is mounted on the support plate 40. The sleeve 60 can slide along the support rod 20 of the frame 20, and the support plate 40 is coupled to the sleeve 60 such that the support plate 40 slides with respect to the frame 20. One end of each spring 50 is connected with the frame 20, the other end of each spring is connected with the support plate 40, and the four springs 50 provide tension for the support plates; when the support plate 40 slides relative to the frame, the spring 50 restrains the support plate 40 to return to an intermediate position where a certain load is applied, and enables the support plate to slide reciprocally relative to the intermediate position. Thus, the load 30 can slide back and forth with respect to the intermediate position of the constant load by the weight reduction mechanism, thereby reducing the impact and pressure of the load 30 on the human body.

In addition to the embodiments described herein, those skilled in the art will be able to employ other technical solutions which are obvious based on the disclosure of the claims and the specification of the present application, and these technical solutions include technical solutions which employ any obvious replacement or modification of the embodiments described herein.

The drawings in the present specification are schematic views to assist in explaining the concept of the present invention, and schematically show the shapes of the respective portions and the mutual relationships thereof. It should be noted that the drawings are not necessarily drawn to the same scale in order to clearly illustrate the structures of the various components of the embodiments of the present invention. The same reference numerals are used to designate the same or similar parts.

Fig. 1 shows a schematic plan view of the whole of the suspension backpack embodiment of the present invention, referring to fig. 1, the suspension backpack of the present invention comprises: a bag 1; a suspension weight-reducing mechanism 2; a backing 3; and a harness 4.

Further, referring to fig. 2-3, fig. 2 is a schematic plan view of the back and straps of the suspension backpack embodiment of the present invention, and fig. 3 is a schematic plan view of the suspension backpack embodiment of the present invention after the back is unfolded. The backing 3 comprises: a cushion 32; a cover 33; a bottom surface 38; a zipper 35. As shown in fig. 2, three cushions 32 are fixedly provided on the cover 33 for cushioning the pressure when the backpack is in contact with the back of a human body. The zipper 35 includes a pull tab 351 that movably joins the cover 33 and the base 38 together. As shown in fig. 3, the bottom surface 38 and the back strap 4 may be secured to the weight-reducing mechanism 2, specifically to the back plate 21 of the weight-reducing mechanism 2, by fasteners F2 and F3 (see also fig. 3).

In the illustrated embodiment, the cover 33 and bottom 38 of the backing 3 are movably joined together by means of zippers 35 for the purpose of facilitating the installation of the backpack and its weight-reducing mechanism. However, the backing 3 may be formed without the zipper 35 and in other configurations, such as by snapping the cover 33. Since the back lining 3 does not take over the function of the load-reducing mechanism 2 and the bag 1, and the load-bearing function is achieved by the straps 4 which are firmly fixed to the load-reducing mechanism by means of the fixing elements and the hold-down strips, the connection and the structural form of the back lining can be designed flexibly, as long as it covers the back side of the suspended backpack and facilitates the mounting of the backpack and its load-reducing mechanism.

Fig. 4 is a perspective view of an embodiment of a suspension weight reduction mechanism according to the present invention. The weight reduction mechanism 2 is a drawer-type box-shaped structure, and the support body thereof comprises a back plate 21 and a wrapping plate 22, and a left energy storage mechanism and a right energy storage mechanism (see fig. 9, which will be described in detail below) of the suspension weight reduction mechanism 2 are mounted on the back plate 21 and the wrapping plate 22, that is, the box-shaped structure formed by the back plate 21 and the wrapping plate 22 accommodates the left energy storage mechanism and the right energy storage mechanism therein. Back panel 21 connects backing 3 and back strap 4 and flap 22 connects bag 1.

The fasteners F1, F2, F3 and F4 are shown in fig. 4, the mounting positions of which can be seen in connection with fig. 3: the fastener F4 in fig. 4 is hidden by the bottom surface 38 of the backing 3, which is used to fasten one end of a spring, such as a hanger that may be used to fasten one end of a spring; fasteners F3 and F2 are used to fasten the bottom surface 38 and the back strap 4 by means of compression straps 36 and 37, respectively, FIG. 4 shows fasteners F3 and F2 fastened to the back panel 21, and in the actual configuration fasteners F3 and F2 clamp the backing and the back strap by means of compression straps; in addition, bottom surface 38 covers axles 231, 231 ', 251, and 251' of the pulleys and nuts 232, 232 ', 252, and 252' that are threaded onto these axles to secure the pulleys.

The utility model discloses a suspension knapsack be used for losing the mounting that heavy mechanism and back lining and braces are connected and the suspension subtracts the mounting of heavy mechanism and all be the same model with the suspension, for example, the nut can be the same model in these mountings, and the model of screw also can be the same, or the threaded diameter of the fixed axle of pulley is the same with the threaded diameter of screw. This simplifies the structural parts.

Further reference is made to fig. 5-8, where fig. 5-6 show perspective views of wrapper 22 and back plate 21, respectively, fig. 7 is a schematic plan view of back plate 21 with energy storage mechanism components and fixtures installed, and fig. 8 is a schematic plan view of wrapper 22 with balance and fixture installed.

Both the packing plate 22 and the back plate 21 are support plates, and in the present embodiment, both the packing plate 22 and the back plate 21 are made of carbon fiber and both include hems and hems. As shown in fig. 5, the covering plate 22 includes a main surface 223 thereof, a hem 222, and a covering edge 221, and the hem 222 and the covering edge 221 are formed by continuously bending on both sides of the main surface 223. As shown in fig. 6, the back sheet 21 includes its main surface 212, a folded edge 211, and a covered edge 218, and the folded edge 211 and the covered edge 218 are also formed by continuously bending on both sides of the main surface 212. As shown in fig. 4, the hem 222 and the hem 221 of the covering 22 accommodate the back sheet 21 in the covering 22 and restrict the back sheet 21 to slide in the hem 221 of the covering 22, and the hem 218 of the back sheet 21 abuts against the main surface 223 of the covering 22 to form a self-sliding movement. Naturally, since the covered edge 221 of the covering sheet 22 restricts the back sheet 21 to slide within the covering sheet 22, the covered edge 221 of the covering sheet 22 comes into contact with the main surface 212 of the back sheet 21 and also forms a self-abrasion slide.

In the present embodiment, the covering 221 of the covering plate 22 and the covering 218 of the back plate 21 are preferably 5-8 mm, which can satisfy the sliding and fixing requirements and is also beneficial to the processing of the carbon fiber plate.

Although the present embodiment shows both the sheathing board 22 and the back board 21 having the sheathing, the back board 21 may not have the sheathing, and the top of the folded edge 211 of the back board 21 directly abuts against the main surface 223 of the sheathing board 22 to form a self-sliding motion.

In addition, although in the drawer-type box structure of the weight-reducing mechanism 2, the illustrated embodiment is that the folded edge 222 and the wrapped edge 221 of the wrapping plate 22 accommodate the back plate 21 in the wrapping plate 22 and are limited to slide in the wrapped edge 221 of the wrapping plate 22, the drawer-type box structure of the present invention may also adopt such a manner: the flap 211 and the hem 218 of the back panel 21 accommodate the wrapper 22 within the back panel 21 and are constrained to slide within the hem 218 of the back panel 21.

As shown in fig. 5, the side of the main surface 223 of the wrapper 22 has through holes 224, 9 through holes 224 being shown by way of example, and the through holes 224 are used for installing fasteners F1 for fastening the wrapper 22 to the bag 1. The central portion of main surface 223 of wrapper 22 also has two through holes 225 for mounting the balance of the left and right energy storing mechanisms on wrapper 22.

As shown in fig. 6, the back panel 21 has a through hole 213 at the upper side of the main surface 212 for mounting a fixing member F2 for fixing the upper ends of the backing 3 and the back band 4 to the back panel 21. The back panel 21 also has through holes 216, 214 and 215 on both sides of the main surface 212, the through hole 216 being used for mounting the pulleys of the left and right energy stocking mechanisms, the through hole 214 being used for mounting the fixing member F3 for fixing the lower end portion 41 of the back 3 and the back belt 4 to the back panel 21, and the through hole 215 being used for mounting the fixing member F4 for fixing the left and right energy stocking mechanisms to the back panel 21. Also formed in the main surface 212 is a mounting hole 217 for mounting a cable of the left and right energy storage mechanisms.

Referring to fig. 9, it is a schematic plan view of a first arrangement example of the energy storage mechanism of the suspension weight reduction mechanism of the present invention, in which the aforementioned left and right energy storage mechanisms of the suspension weight reduction mechanism 2 are symmetrically installed in the drawer-type box structure in a manner of being supported on the back plate 21 and the wrapper plate 22, the left energy storage mechanism includes a first fixed pulley 23, a balance 24, a second fixed pulley 25, a spring 27, and a cable 26, and the right energy storage mechanism includes a first fixed pulley 23 ', a balance 24 ', a second fixed pulley 25 ', a spring 27 ', and a cable 26 '. The arrangement, installation, operation and function of the left and right side energy storage mechanisms will be described in detail later in connection with the description of the other components.

Referring back to fig. 7, the back plate 21 is generally rectangular, and is continuously bent on both sides of a rectangular main surface 212 to form a folded edge 211 and a covered edge 218, and a mounting hole 217 is formed in the main surface 212 for mounting a cable of the energy storage mechanism in place. In the present embodiment, most components of the left energy storage mechanism including the first fixed pulley 23, the second fixed pulley 25, the spring 27, and the cable 26 on the main surface 212 and the right energy storage mechanism including the first fixed pulley 23 ', the second fixed pulley 25', the spring 27 ', and the cable 26' on the main surface 212 are symmetrically arranged on the main surface 212. Fasteners F2 and F3 are also supported on major surface 212 to secure back panel 21 with backing 3 and back belt 4. The other ends of the fasteners F2 and F3 shown in fig. 3 and 4 are shown in fig. 7.

Referring again to fig. 8, wobblers 24 and 24 'are symmetrically mounted on wrapper 22, with the axes of wobblers 24 and 24' fixed relative to wrapper 22. The securing element F1 is supported on the main surface 223 so as to secure the wrapper 22 with the bag 1. The other end of the fastener F1 shown in fig. 4 is shown in fig. 8.

After the first fixed pulley, the second fixed pulley, the spring, and the cable are mounted on the back plate 21 and the balance is mounted on the wrapper 22, the back plate 21 is inserted into the wrapper 22 as shown in the drawing to join the back plate 21 and the wrapper 22 together, and then the cables 26 and 26 'are respectively hung, i.e., mounted, on the balances 24 and 24' using the mounting holes 217 of the back plate 21, thus completing the assembly of the weight-reducing mechanism 2. After the assembly of the suspension weight-reduction mechanism 2 is completed, the left energy storage mechanism and the right energy storage mechanism are arranged as shown in fig. 9. Note that, when assembling the left and right energy stocking mechanisms, the springs 27 and 27 ' tension the cables 26 and 26 ' in a pretensioned manner, and the cables 26 and 26 ' are pretensioned. That is, the cables 26 and 26 ' are pre-tensioned after the cables 26 and 26 ' are hooked to the wobblers 24 and 24 ', respectively.

As shown in fig. 4, the left energy storage mechanism and the right energy storage mechanism are accommodated in the hollow space of the box-shaped structure formed by the back plate 21 and the wrapping plate 22, and as a weight reduction mechanism of the suspension backpack, the hollow space between the back plate 21 and the wrapping plate 22 can be designed according to the requirement, for example, the distance between the back plate 21 and the inner side of the main surface of the wrapping plate 22 is 22 mm, which is a preferred dimension after the inventor carefully considers the structure, and of course, the hollow space can be designed into other dimensions according to the requirement. In the specific design of the suspension weight reducing mechanism of the present invention, the pulleys, the balance wheels and the springs of the left energy storage mechanism and the right energy storage mechanism may be arranged to be substantially located on the same plane; on the other hand, the pulley, balance and spring of left side energy storage mechanism and right side energy storage mechanism can set up to stagger, and not all lie in the coplanar promptly, for example, the plane at balance place can stagger with the plane at pulley place, under such a condition, the utility model discloses a left side energy storage mechanism and right side energy storage mechanism still can realize its function, can work. Planes of the pulleys, the balance wheels and the springs of the left energy storage mechanism and the right energy storage mechanism can be staggered or positioned on the same plane, and the planes can be determined in specific design as long as the left energy storage mechanism and the right energy storage mechanism can realize functions and complete work. Of course, from a mechanical point of view, it is a preferred state of operation for the cable and spring that the pulley, balance and spring are arranged to be substantially in the same plane.

The folding angle of the folded and hemmed edges of the back sheet 21 and the covering sheet 22 is preferably 90 degrees, and the size of the hemmed edge is preferably 5 to 8 mm. The 5-8 mm hemming is an easy-to-handle size for carbon fiber processing and is sufficient to perform the hemming function.

Referring again to fig. 9, the left and right energy storage mechanisms are symmetrically arranged, the first and second fixed pulleys are arranged in the relative sliding direction of the back plate 21 and the wrapper plate 22, and the two balance wheels are arranged between the two sets of the first and second fixed pulleys, so that each set of the first fixed pulley, the balance wheels, and the second fixed pulley forms a triangular arrangement, and the balance wheels are located between the first fixed pulley and the second fixed pulley in a state where the weight-reduction mechanism 2 is not loaded.

The two cables 26 and 26' are connected at one end to the first fixed pulley, and in this embodiment, the cable is looped around the first fixed pulley in a manner that the cable end forms a loop since the first fixed pulley is the starting end of the cable. The cables 26 and 26' then respectively pass around the balance and compress it, and then pass around the second fixed pulley. Finally, the other ends of the cables 26 and 26' are each connected to one end of a respective spring. After the cables 26 and 26 ' are installed, the springs tension the cables 26 and 26 ' in a pretensioned manner, thereby pretensioning the cables 26 and 26 '. In the solution of the suspension weight reducing mechanism of the present invention, it is an indispensable feature that the cable is pre-tensioned, so that the balance has an initial position, and the balance can reciprocate under different load conditions to achieve a weight reducing effect.

Note that in the present embodiment, the fixed pulleys 23, 23 ', 25 and 25' and the balance wheels 24 and 24 'are each provided with a groove in the rim portion so that the springs 26 and 26' are mounted and positioned on the fixed pulleys and the balance wheels. The springs 26 and 26 'are in direct contact with the recesses of the fixed pulleys and balances, the bottoms of which are indicated in fig. 9 by the dashed circles, which have the references 233, 233', 243 ', 253 and 253', respectively, in fig. 15.

The connection form of the cable and the first fixed pulley is not limited to the collar formed by the end of the cable shown in the embodiment, but may be other forms, such as a separate ring buckled on the first fixed pulley, and then the cable is connected to the ring buckle. Or the end of the inhaul cable is fixed on the first fixed pulley.

As shown in fig. 9, wobblers 24 and 24 'have axial centers O1 and O1', respectively, and the angles α and α 'between the cable around the wobbler and the horizontal line, i.e. the line passing through axial centers O1 and O1', are a very important parameter of the solution of the invention, which may be between 5 and 30 degrees, for example between 10 and 20 degrees, for example 10 degrees. In the case of no load on the left and right energy storage mechanisms, the angle of the cable between the first fixed pulley, the balance and the second fixed pulley is twice the angle a and a', respectively, i.e. the angle may be between 10-60 degrees, such as 20-40 degrees, e.g. 20 degrees, due to the cable being pretensioned by the spring. The angle value that keeps this parameter is right from the angle of mechanics and from making the balance reciprocate for a certain position study, and the operation that keeps this parameter has important meaning to the utility model discloses a left side energy storage mechanism and right side energy storage mechanism could make left side energy storage mechanism and right side energy storage mechanism steady operation, could make the balance can both well reciprocating motion and play the effect that subtracts the heavy under the condition of different loads, for example, also can well reciprocating motion and play the effect that subtracts the heavy under the condition of little heavy burden.

In the structure of the double pulley and the double balance of the present invention, when the balance is loaded, the extension of the spring is not linear, that is, the change in the length of the cable moving from the second fixed pulley to the balance is not linear. In addition, the distance that the balance moves downward when the balance is loaded is also not linear. The utility model discloses a suspension subtracts heavy mechanism's left side energy memory and right side energy memory have combined the pulley, cable and spring, form to triangle-shaped and guarantee under the condition of alpha and alpha' angle value between assurance fixed pulley and the balance, select the performance parameter and the suitable pretightning force of spring, can accomplish to make the balance with a certain central point position reciprocating motion and play and subtract heavy effect under the circumstances of bearing a burden of difference, even be under the less circumstances of bearing a burden, the balance also can be reciprocating motion well.

The inventor of the present application has made experiments and, under specific design conditions of the left energy storage mechanism and the right energy storage mechanism, for example, performance of a spring is determined, a size of a triangle formed between a fixed pulley and a balance wheel is determined, angle values of α and α' are determined, and a nonlinear relationship is formed between a load increase and a distance of a position descent of the balance wheel. The distance of the balance wheel position descent is related to the mass of the load, the parameters of the spring, the dimensions of the triangle and the values of the angles α and α', and the relationship between the load increase and the distance of the balance wheel position descent under certain conditions can only be determined directly by experiments. After the values of the angles α and α' are determined, the choice of the performance of the spring is another major factor, and there are many choices for a particular design, and those skilled in the art can make different choices for the number and performance of the springs according to the particular needs of the product. In the embodiment, only one spring is shown in each of the left energy storage mechanism and the right energy storage mechanism, however, one skilled in the art can design two or more springs in one energy storage mechanism, and the springs can be connected in parallel or in series.

The utility model discloses a cable should be tough and tough durable, can bear the design intensity.

For the arrangement of the energy storage mechanism shown in fig. 9, an example of relevant dimensions may be given here as a reference. For example, the diameter of the first and second fixed pulleys and the balance wheel is 30 mm, and the depth of the groove is 1.5 mm; the distance between the first fixed pulley and the second fixed pulley in each set of energy storage mechanisms is 60 mm, the distance between the centers of the two balance wheels is 34 mm, and the horizontal distance between the balance wheels in each set of energy storage mechanisms and the first fixed pulley and the second fixed pulley is 63 mm, so that the distance between the fixed pulleys of the two sets of energy storage mechanisms is 160 mm.

With respect to fig. 9, fig. 10 is a schematic plan view showing downward movement of the balance in the first example of arrangement of the energy storing mechanism of the weight reducing mechanism of the present invention, and fig. 11 is a schematic plan view showing upward movement of the balance in the first example of arrangement of the energy storing mechanism of the weight reducing mechanism of the present invention, which show the reciprocal movement of the balance, that is, the wrapper of the embodiment shown in fig. 3. In fig. 10, the two wobblers move downward by receiving a load, and the axial center moves from O1 and O1 'to O2 and O2' respectively with respect to the fixed pulleys, and the length of the cable between the two fixed pulleys increases. Referring to fig. 11 again, due to the tension of the spring and the inertia of the pre-tightening force and the elastic force, the balance wheels will move in opposite directions after the two balance wheels are loaded and move downwards, and as shown in fig. 11, the axes of the two balance wheels move upwards to O2 and O2'. Then, the two balance wheels move downward again by inertia of the load, the tension of the spring, and the elastic force. Whereupon it moves upwards again. Thus, the balance appears to move back and forth relative to a central position under a certain load.

Referring again to fig. 10, it is shown that the shift of the centre of gravity of the balance is evident, and the increase in the length of the cable between the two crown pulleys is evident. However, when the balance weight is small, the distance of the movement of the axis of the balance relative to the fixed pulleys is short, and at this time, the change in length between the balance and one fixed pulley is small, so that the increase in length of the cable between the two fixed pulleys is extremely limited, and thus, when the weight is small, the reciprocating movement of the balance is mainly affected by the preload, and the influence of further stretching of the spring is small, so that the balance can reciprocate well and smoothly even if the weight is small, and a good weight reduction effect is achieved. This is why the present invention can achieve a good weight reduction effect even with a small load.

Fig. 12 is a plan view schematically showing a second example of arrangement of the energy storing mechanism of the weight-loss mechanism according to the present invention, in which the wobbles 24 and 24 'are not located between the two sets of fixed pulleys but located outside the two sets of fixed pulleys, that is, the two sets of fixed pulleys are located between the two wobbles 24 and 24', as compared with the first example of arrangement. Each set of first fixed pulley, balance, second fixed pulley is still required to form a triangular arrangement and, without load, the angle between the cable around the balance and the horizontal, i.e. the line passing through the axes O1 and O1', is required to be between 5-30 degrees, for example 10-20 degrees, for example 10 degrees. Fig. 13 is a schematic plan view showing a downward movement of the balance in the second arrangement example of the energy storing mechanism of the weight reducing mechanism of the present invention, and fig. 14 is a schematic plan view showing an upward movement of the balance in the second arrangement example of the energy storing mechanism of the weight reducing mechanism of the present invention, which schematically show a reciprocating state of the balance in the second arrangement example.

The second example of arrangement is similar to the first example of arrangement described above, except that the two balances 24 and 24' are located outside the two sets of fixed pulleys, and the structure and performance of the second example of arrangement can be seen from the description of the first example of arrangement described above and will not be described again here.

The arrangement of the third arrangement example, which is staggered in the relative sliding direction of the back plate and the packing plate, can increase the arrangement selectivity of the energy storage mechanism on the back plate and the packing plate, thereby facilitating the selection of the structural size, the selection of the number and the performance of the springs and the selection of the mechanical performance of the mechanism. The third arrangement example is similar to the first arrangement example described above except that the first fixed pulleys and the second fixed pulleys are staggered in the relative sliding direction of the back plate and the sheathing plate, and the structure and performance thereof can be referred to the description of the first arrangement example described above, and will not be described again here.

Fig. 16 is a plan view schematically showing a fourth example of the arrangement of the energy stocking mechanism of the suspension weight-reducing mechanism of the invention, which adds third fixed pulleys 28 and 28 'as compared with the previous example of the arrangement, the third fixed pulleys 28 and 28' are also fixed to the back plate 21, provided between the second fixed pulley and the spring, and the cable is routed around the third fixed pulleys 28 and 28 'after extending from the second fixed pulley to the third fixed pulleys 28 and 28' until being connected to one end of the spring. The third fixed pulleys 28 and 28 'have grooves 283 and 283', respectively. As shown in fig. 16, the position and orientation of the springs 27 and 27' are changed from the previous example, thereby increasing the selectivity of the arrangement of the energy storage mechanism on the back plate and the wrapper plate, facilitating the choice of the size of the structure, the number and performance of the springs, and the mechanical performance of the mechanism. Other structures and performances of the fourth arrangement example are similar to those of the first arrangement example described above except that the third fixed pulley is added to change the direction and position of the spring, and therefore, other structures and performances of the fourth arrangement example and the overall structure and performance thereof can be referred to the description of the first arrangement example described above and will not be described herein again.

It should be noted that, although the suspension weight reduction mechanism in the foregoing embodiment employs a structure in which the wrapper plate accommodates the backboard and the movement of the backboard is restricted by the wrapping, the embodiment of the present invention may also employ a structure in which the backboard accommodates the wrapper plate and the movement of the wrapper plate is restricted by the wrapping of the backboard.

In addition, in the above embodiment, the balance wheel of the weight-reduction mechanism is fixed to the main surface of the wrapper and the other components of the energy storage mechanism are mounted on the back plate, but the embodiment of the present invention may also adopt the opposite structure, that is, the balance wheel is fixed to the main surface of the back plate and the other components of the energy storage mechanism are mounted on the wrapper. Such variations would be readily understood and readily implemented by those skilled in the art.

Similarly, it is possible to provide flexibility even if the components of the energy storage mechanism are mounted to the wrapper or to the backplate, for example, by mounting the balance and spring to the wrapper or to the backplate simultaneously. Therefore, for the arrangement mode that each part of the energy storage mechanism is arranged on the wrapping plate or the back plate, the energy storage mechanism can meet the design requirement, the mechanism runs smoothly, and the reciprocating motion can be realized to obtain the effect of reducing weight.
