Description

Technical Field

[0001] This application relates to the field of accessories for water facilities, specifically a support structure for water facilities. More specifically, the water facilities of this application can be hard boats, inflatable boats or similar water facilities. In a specific example, it relates to the field of hull accessories, especially the field of inflatable boat accessories, specifically an inflatable boat support structure. Background Art

[0002] With the continuous enrichment of the current outdoor water sports supply, outdoor water sports are breaking through the niche sports circle and becoming the new favorite of the public. An inflatable boat is an inflatable boat that can be packed small enough to fit into a backpack. Compared with ordinary inflatable kayaks, inflatable boats are lighter, easier to use, have a longer material life, higher reliability, and a smaller storage volume. Specifically, inflatable boats have the following advantages: (1) Lightweight: The weight is between 2 - 6 kilograms; (2) Heavy load: The load weight usually ranges between 150 - 300 kilograms; (3) Easy to store: It is often easy to pack into the size of a sleeping bag and can be easily put into a backpack; (4) Strong compatibility: It can be taken along when hiking, camping, self-driving, cycling, or motorcycle touring, allowing users to explore more possibilities.

[0003] Inflatable boats are easy to carry and hike, can be quickly folded, inflated, deflated, and quickly assembled and used when needed. When using an inflatable boat, the user inflates the inflatable boat, places it on the water, and then places himself on the bottom plate of the inflatable boat to start rowing.

[0004] The applicant found in practice that after using an inflatable boat for a certain period of time, users will experience a large amount of fatigue in the waist and back. How to reduce the fatigue of the waist and back of inflatable boat users while taking into account the characteristics of existing inflatable boats has become an urgent technical problem for the applicant to solve.

[0005] Furthermore, for water facilities such as kayaks and canoes, there is also a corresponding need for waist and back support for users. Summary of the Invention

[0006] The inventor analyzed and believed that the main reasons for users to experience fatigue are as follows: (1) Some inflatable boats use inflatable backrests. After users lean on them for a long time, there is always too much pressure concentrated around the spine, resulting in a decrease in comfort; (2) Some inflatable boats use EVA foam backrests. However, due to the limitation of the traditional structure, the center point of the backrest position cannot be higher than the highest point of the gunwale. For users, the backrest is still too low to provide effective support for the waist and back, resulting in a decrease in comfort; (3) Some kayaks are equipped with a metal frame support structure that can provide relatively high back support. However, this metal frame is difficult to fold into a bag, is relatively heavy, and inconvenient to carry.

[0007] The object of the present invention is to provide a support structure for water facilities that can provide high lumbar and dorsal support for users. The support structure for water facilities in this application adopts a detachable structure design, which is convenient for storage and folding and does not affect the structure of existing water facilities. The support mechanism in this application can provide lumbar and dorsal support for users, effectively reducing the fatigue of the users' lumbar and dorsal regions, thereby enhancing the fun of water sports. This application can adapt to various water facilities, including but not limited to hard boats, inflatable boats or similar water facilities, and has strong adaptability. Further, when the water facility is an inflatable boat, it can provide lumbar and dorsal support for the users of the inflatable boat.

[0029] A number of process holes are provided on the sixth flexible support sheet.

[0030] In this application, the third connecting rod is connected to the back mesh pad, and the height of the back mesh pad is lifted through the third connecting rod. The third connecting rod serves as the main support mechanism. The third lower end jacking member is used to limit the lower end of the third connecting rod, and the third upper end jacking member is used to limit the upper end of the third connecting rod. At the same time, one end of the second fixing belt is connected to the back mesh pad or the third upper end jacking member, and the other end of the second fixing belt is connected to the third lower end jacking member through the second connecting component.

[0033] Furthermore, when this support structure is used as the front backrest or the middle backrest of a water facility, the included angle between the two third connecting rods is within 10° (i.e., when the two third connecting rods are approximately parallel), so a fifth back connecting component needs to be used for auxiliary support. In the fifth back connecting component, a fifth T-shaped clamping member is designed, and the fifth T-shaped clamping members are respectively arranged at both ends of the fifth connecting rod, which can be quickly installed and released.

[0034] When this inflatable boat support structure is used as the backrest of an inflatable boat, since the installation position is close to the folding part of the boat body, the included angle between the two third connecting rods is greater than or equal to 20°. The pressure between the user's back and the back mesh pad gives the back mesh pad itself stability, so there is no need to use an additional fifth back connecting component.

[0035] This application adopts the currently known lightest method to achieve the most sufficient lumbar and back support, which cannot be achieved by the prior art. Brief Description of the Drawings
