Description

Technical Field

[0001] The invention relates to the technical field of folding tents, in particular to an automatic eaves mechanism for folding tents. Background Art

[0002] Folding tents, also known as advertising tents and awnings, can be used for outdoor exhibitions, product promotions, celebrations, trade shows, tourism and leisure activities, field work, and food stalls. They can be used for temporary events like singing and dancing parties, or as long-term leisure facilities in parks, tourist resorts, and scenic areas. They are simple to operate and install. For portability, especially for small and medium-sized folding tents, the interior space is relatively small. To increase the shade area when the tent is opened, cantilevered tents have emerged. These tents feature cantilevered poles extending from the top corners, which are then reinforced with a rim to increase the shade area.

[0003] Existing cantilever structures usually form an outward cantilever structure by pivoting or inserting a cantilever rod on the top rod of the tent roof support. For example, the announcement number CN209443880U discloses a tent cantilever support structure, which is fixed on the leg tube of the tent and includes two cantilever rods and a fixed rod; the two ends of the fixed rod are respectively connected to the two cantilever rods, and the two cantilever rods are respectively connected to the two leg tubes of the tent through connecting parts; the connecting parts include a first clamping arm, a second clamping arm, a rotating head and a fixing bolt. However, during use, it is necessary to operate in two steps when unfolding or folding. That is, when unfolding, the tent main body support must be unfolded first, and then the cantilever rods must be opened and pulled out one by one, or assembled separately to complete the erection of the cantilever frame. Since the cantilever rods are at a high position, it is not convenient to operate. Folding is the opposite and the same problem exists.

[0004] To this end, the announcement number CN204238639U discloses a folding tent eaves frame mechanism, including a tent frame and an eaves pole, the tent frame including a column, a tent pole and a strut, the top of the column is fixed with a fixed seat, the column is slidably connected to a slide that can slide up and down along the column, the end of the tent pole is pivotally connected to the fixed seat, the first end of the strut is pivotally connected to the slide, and the second end of the strut is pivotally connected to the tent pole, and the tent frame can be driven to expand or fold by sliding the slide up and down along the column; the fixed seat is provided with a slide; the strut is slidably connected to a connecting seat, the first end of the eaves pole is pivotally connected to the connecting seat, and the second end of the eaves pole can be extended or retracted and movably connected to the slide to drive the eaves pole to expand or fold. Although it can realize automatic extension and retraction of the eaves, the eaves pole (eaves pole) needs to be limited and extended by a slide (long hole structure), but the slide and the eaves pole are usually matched with a gap, which leads to the problem of obvious shaking of the eaves pole when the folding tent is fully unfolded. Especially in windy conditions, combined with the tent cloth, it is very easy to cause the folded tent to shake, seriously affecting the user experience; in addition, its connecting seat slides along the support pole. When the tent is fully unfolded, the connecting seat is easily affected by external force, causing it to slip backward, affecting the unfolding effect of the eaves pole.

[0005] In addition, announcement number CN112031514A discloses a folding tent with an automatically retractable eaves structure, including tent leg tubes, a tent roof pole, and a strut. The upper ends of the tent leg tubes are equipped with mounting seats, one end of the tent roof pole is hinged on the mounting seat, and the leg tube slide can move along the tent leg tubes. The tent leg tubes are also equipped with leg tube slides, and the leg tube slides are used to cooperate with the struts. The front end of the strut is hinged to the tent roof pole for opening or retracting the tent roof pole. The mounting seat is provided with an eaves sliding sleeve, which is movable relative to the mounting seat. The eaves sliding sleeve is used to cooperate with the eaves rod, and the eaves rod can slide along the eaves sliding sleeve to extend outward or retract inward, and the eaves rod includes a first eaves rod and a second eaves rod deflected relative to the first eaves rod, and one end of the second eaves rod is used to movably cooperate with the strut.

[0006] However, the above technical solutions include the solutions previously applied for by the applicant. During use, when the connecting seat slides along the support rod, it needs to drive the eaves rod to extend outward, and it is easy to get stuck during the extension process, making the extension unreliable.

[0007] Figure 1 This is a structural diagram of the eaves rod being stuck during extension.

[0008] When the tent is opened, the leg tube slider 5a moves upward, driving the awning top rod to rise through the support rod 6a. At the same time, the connecting seat 7a on the support rod 6a is also driven to move upward, thereby pushing the eaves rod 2a to rise. If the user opens the tent slowly, during this process, due to the center of gravity of the eaves rod 2a itself rising above the outer side of the eaves slider 3a, the eaves rod 2a will flip outward (i.e., the right side shown in the figure) under the action of its own gravity.

[0009] However, in the case of a faster opening action, the eaves rod 2a does not have time to flip, and the following Figure 1 jamming phenomenon will occur: the connecting seat 7a fails to move to and exceed the critical position shown by the dotted line in the figure in time (i.e., the outer included angle between the eaves rod 2a and the support rod 6a is greater than 90°), and the bent part of the eaves rod 2a has already abutted against the eaves slider 3a and cannot continue to move upward. According to the principle of force synthesis and decomposition, at this time, the more the leg tube slider 5a is pushed upward, the more the connecting seat 7a is stressed along the lower end direction of the support rod 6a and cannot move upward along the upper end direction of the support rod 6a to turn the eaves rod 2a outward, resulting in jamming and the tent cannot be opened.

[0010] The root cause is that: during the opening process of the tent, the connecting seat 7a does not receive an upward pulling force along the direction of the support rod 6a. It only relies on the eaves rod 2a to flip due to its own gravity during the opening process and is not easy to move upward along the support rod 6a. The eaves rod 2a is extremely easy to jam and cannot be smoothly extended. Summary of the Invention

[0011] The purpose of the present invention is to provide an automatic eaves mechanism for a folding tent to solve the above technical problems and make the eaves extension activity smoother and more stable.

[0012] The technical problems solved by the present invention can be realized by the following technical solutions:

[0013] An automatic eaves mechanism for a folding tent includes a tent leg tube and a tent support rod for supporting the tent top tarpaulin. An installation seat is provided on the upper part of the tent leg tube. One end of the tent support rod is cooperatively installed with the installation seat. A slider that can slide up and down along the tent leg tube is also provided on the tent leg tube. An inclined rod is hingedly cooperated on the slider. The other end of the inclined rod is hinged to the tent support rod. An eaves sleeve is hingedly provided on the installation seat. The eaves rod is cooperatively installed with the eaves sleeve. The eaves rod can telescopically move along the eaves sleeve. The middle part of the eaves rod has a fixed bending structure. It also includes a linkage rod. The inner end of the linkage rod is hinged to the tent support rod. The hinged point of the linkage rod and the tent support rod is located inside the hinged point of the inclined rod and the tent support rod. A sliding device is provided on the inclined rod. The linkage rod and the sliding device are hinged. The inner end of the eaves rod is hinged on the linkage rod; when the folding tent is unfolded, the tent support rod drives the linkage rod to slide along the inclined rod as a track, and the linkage rod pulls the eaves rod to complete the eaves extension; when the folding tent is contracted, the tent support rod contracts, thereby driving the linkage rod to push the eaves rod to complete the contraction.

[0014] The cornice rod is of an integral or split structure. The fixed bend of the cornice rod can be an arc inflection point or a bending inflection point. When the cornice rod completes the cornice extension, the arc inflection point or the bending inflection point is close to or located at the inner end port of the cornice sleeve.

[0015] The cornice rod can be a straight rod structure instead of a fixed bend structure.

[0016] The sliding device adopts a sliding sleeve or a sliding trolley with an inclined rod as a track.

[0017] The sliding device adopts a slider, and a chute is opened on the inclined rod. The slider is used for sliding cooperation with the chute.

[0018] The cornice rod is hinged to the outer end of the linkage rod, and the sliding device is hinged to the middle of the linkage rod.

[0019] The cornice rod is hinged to the middle of the linkage rod, and the sliding device is hinged to the outer end of the linkage rod.

[0020] Both the cornice rod and the sliding device are hinged to the outer end of the linkage rod.

[0021] The linkage rod is in the shape of a long strip thin plate structure.

[0022] The cornice sleeve is hinged to the mounting seat on the upper part of the tent leg tube. The cornice sleeve allows the cornice rod to freely slide in its inner hole, and the cornice sleeve can freely swing around the hinge point.

[0023] Compared with the prior art, the present invention has the following outstanding advantages and effects: Through optimized design, the present invention uses the linkage rod as a linkage component, and uses the extension of the tent strut to drive the extension of the linkage rod, thereby driving the cornice rod to complete the extension; compared with the prior art that uses a sliding seat to drive the inclined rod to slide, and then uses a connecting seat to drive the cornice rod, the power transmission of the present invention is more direct and effective, making the extension or contraction of the cornice rod smoother; by using the restriction of the linkage rod on the cornice rod and combining with the cornice sleeve, the installation of the cornice rod is more stable; by choosing the hinge position of the cornice rod and the linkage rod, the length dimension of the cornice rod is adjustable, and the applicability is stronger.

[0024] The features of the present invention can be clearly understood by referring to the drawings of this case and the following detailed description of the preferred embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below with reference to specific drawings.

[0040] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings. At the same time, there are specific position relationship descriptions in the specification text, which are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, specific orientation structure and operation. Therefore, it should not be understood as a limitation to the present invention. Similarly, similar terms such as "one", "first", "a" or "the" do not indicate a quantity limitation, but indicate the existence of at least one.

[0041] As Figures 2 to 13 shown, an automatic eaves mechanism for a folding tent provided by the present invention includes a tent leg tube 1 and a tent support rod 2. Common folding tents in the prior art include four tent leg tubes 1 and four tent support rods 2 extending from the upper ends of the tent leg tubes 1 towards the center. Usually, a folding side rod assembly is also provided in cooperation between the tent leg tubes 1. The tent support rod 2 is usually composed of two or more folding rods hinged together. The folding tent structure is a common structure in the prior art and can be divided into folding tents with a central lock, business tents with an upper middle long top rod, ordinary folding tents unlocked by a sliding seat on the leg tube, etc. At the same time, there can also be folding tents with two or more tent tops.

[0042] Among them, an installation seat 4 is provided on the upper part of the tent leg tube 1. One end of the tent support rod 2 is installed in cooperation with the installation seat 4. A sliding seat 7 that can slide up and down along the tent leg tube 1 is also provided on the tent leg tube 1. An inclined rod 6 is hinged and cooperated on the sliding seat 7. The other end of the inclined rod 6 is hinged and cooperated with the tent support rod 2. Usually, the inclined rod 6 is hinged and cooperated with the outermost folding rod among the tent support rods 2. The tent support rod 2 is used to support the tent top tarpaulin.

[0043] Based on the above, the present invention optimizes the design of the linkage rod 8 component. The inner end of the linkage rod 8 is an end biased towards the center position of the folding tent, and the outer end is an end biased towards the outside of the folding tent. Combining the above folding tent structure, it has an automatic eaves structure, enabling the folding tent to have an eaves mechanism, thereby increasing the sunshade area and improving the overall use experience.

[0044] One end of the linkage rod 8 is used for hinged cooperation with the tent support rod 2. The hinged position on the tent support rod 2 is located on the outermost folding rod. The hinge point between the linkage rod 8 and the tent support rod 2 is located inside the hinge point between the diagonal rod 6 and the tent support rod 2. The center of the folding tent is the interior, and the inner end of the linkage rod 8 is hinged to the tent support rod 2. This hinge point is closer to the center area of the folding tent relative to the hinge point between the diagonal rod 6 and the tent support rod 2. This design feature is to prevent the linkage rod 8 from interfering with the diagonal rod 6 during the process of being driven by the tent support rod 2, and at the same time, it is more conducive to pulling the cornice rod 3.

[0045] One end of the cornice rod 8 is hinged to the linkage rod 8 near or at the outer end. The hinged position between the linkage rod 8 and the cornice rod 3 can be adjusted according to the cornice length of the cornice rod 3. Additionally, different hinged positions with the linkage rod 8 can also be selected according to the shape of the cornice rod 3. The hinge between the linkage rod 8 and the cornice rod 3 can be directly installed through a hinge shaft or realized through a hinge seat for mating installation. Spacers can be provided for the hinge components between the linkage rod 8 and the cornice rod 3 to form a spacing isolation, which can prevent bumps and interferences during folding or stretching. Combining with the illustration, the cornice rod 3 can be a straight rod.

[0046] In this embodiment, when the folding tent is unfolded, the tent support rod 2 drives the linkage rod 8 to extend upward, and the linkage rod 8 pulls the cornice rod 3 to complete the cornice extension. Specifically: when the folding tent is in the contracted state, the folding rod corresponding to the tent support rod 2, which is usually used for hinging with the diagonal rod 6 and the linkage rod 8, is usually hinged to the mounting seat 4 at the upper end and is vertical, usually not in a completely vertical state, and the other end is at the lower end. At the same time, at the center of the folding tent, usually at the center lock or the top plate, the top plate is used for hinged cooperation with the end of the innermost tent support rod 2. When the folding tent is opened, the center of the folding tent moves upward from the lowest position, and each folding rod of the tent support rod 2 extends from the folded state to the unfolded state. The folding rod corresponding to the outermost folding support rod 2 undergoes a position shift, changing from the original vertical state to a horizontal state. As the lower end of the tent support rod 2, which is hinged to the diagonal rod 6 and the linkage rod 8, continuously moves upward, it drives the movement of the diagonal rod 6 and the linkage rod 8, causing the diagonal rod 6 and the linkage rod 8 to also change from the vertical state to the horizontal state. The diagonal rod 6 drives the sliding seat 7 to move upward along the tent leg tube 1 to complete the unfolding of the entire folding tent. During this period, due to being driven by the tent support rod 2, the other end of the linkage rod 8 continuously moves upward. The linkage rod 8 and the cornice rod 3 are in a V-shaped folding state with a small-angle opening and closing. With the pulling of the linkage rod 8, the angle between the linkage rod 8 and the cornice rod 3 continuously increases, usually developing from an acute angle to an obtuse angle, and the maximum opening and closing angle is usually less than 180 degrees, causing the lower end of the cornice rod 3 to continuously move upward and the upper end of the cornice rod 3 to continuously extend outward until the folding tent is completely unfolded.

[0047] In this embodiment, when the folding tent is retracted, the tent pole 2 is retracted, thereby driving the linkage rod 8 to retract, so that the cornice rod 3 is retracted. Specifically, when the folding tent is in the unfolded state, the center of the folding tent moves downward from the highest position, and each folding rod of the tent pole 2 retracts from the unfolded state to the folded state. The folding rod at the outermost end correspondingly moves in position, so that it develops from the original horizontal state to the vertical state. The connecting end of the tent pole 2 hinged to the diagonal rod 6 and the linkage rod 8 continuously moves downward, thereby driving the movement of the diagonal rod 6 and the linkage rod 8, so that the diagonal rod 6 and the linkage rod 8 also develop from the original horizontal state to the vertical state. The diagonal rod 6 drives the sliding seat 7 to move downward along the tent leg tube 1 to complete the retraction of the entire folding tent. During this period, due to the drive of the folding pole 2, the other end of the linkage rod 8 continuously moves downward. The linkage rod 8 and the cornice rod 3 are in a V-shaped folding state with a large-angle opening and closing. With the pulling of the linkage rod 8, the angle between the linkage rod 8 and the cornice rod 3 continuously becomes smaller, usually developing from an obtuse angle to an acute angle, and the minimum opening and closing angle is usually greater than 0 degrees, so that the outer end of the cornice rod 3 continuously contracts inward until the folding tent is completely retracted.

[0048] In one preferred embodiment, a cornice sleeve 41 is sleeved on the middle part of the cornice rod 3. The cornice sleeve 41 is hinged to the mounting seat 4 on the upper part of the tent leg tube 1. The cornice sleeve 41 allows the cornice rod 3 to freely slide in its inner hole, and the cornice sleeve 41 can freely swing around the hinge point. Specifically, the cornice sleeve 41 is hinged and installed on the mounting seat 4. The cornice rod 3 can telescopically move along the cornice sleeve 41. The cornice sleeve 41 is provided with a cornice sliding cavity. The cornice rod 3 penetrates through the cornice sliding cavity to facilitate back-and-forth telescoping. The cornice sleeve 41 and the mounting seat 4 are in a hinged fit, so that as the cornice rod 3 extends or contracts continuously, the position of the cornice sleeve 41 can be adjusted in time, which is beneficial to the sliding of the cornice rod 3. At the same time, by using the cooperation between the cornice sliding cavity in the cornice sleeve 41 and the cornice rod 3, the cornice sliding cavity is usually similar in shape to the cornice rod 3 and is in a sliding clearance fit, which can minimize the lateral offset of the cornice rod 3, thereby improving the overall stability of the cornice rod 3, so as to ensure that the cornice rod 3 does not shake when the folding tent is opened.

[0049] In one preferred embodiment, the cornice rod 3 is of an integral structure, and the cornice rod 3 is of a straight rod structure. The integral structure means that the cornice rod 3 is a straight rod. In this structural design, the cornice rod 3 is usually hinged to the middle position of the linkage rod 8, which can achieve good cooperation.

[0050] In one preferred embodiment, the cornice rod 3 is of an integral or split structure. The cornice rod 3 is provided with an arc inflection point or a bending inflection point. When the cornice rod 3 completes the cornice extension, the arc inflection point or the bending inflection point is close to or located at the inner end port of the cornice sleeve 41. Among them, when the cornice rod 3 is integral, it is usually an arc tube or a part of an arc tube. Among them, when the cornice rod 3 is split, the two ends are connected by a connecting component, and the connecting component is located at the arc inflection point or the bending inflection point, referring to the structure of the cornice rod in the reference publication number CN112031514A.

[0051] In one preferred embodiment, a sliding device 5 is further provided between the linkage rod 8 and the inclined rod 6. The sliding device 5 can make the movement of the linkage rod 8 more stable and smooth, and the sliding device 5 plays a guiding role. Among them, the cornice rod 3 and the inclined rod 6 are respectively located on both sides of the linkage rod 8 to avoid interference and increase the installation stability at the same time.

[0052] In one preferred embodiment, the sliding device 5 includes a sliding sleeve 51 and a linkage seat 52. The sliding sleeve 51 is sleeved on the inclined rod 6 and can slide along the inclined rod 6. The linkage seat 52 is used for hinged cooperation with the linkage rod 8. The sliding sleeve 51 can slide along the inclined rod 6. When playing a guiding role, it can also limit the linkage rod 8 and increase the stability of the movement of the linkage rod 8.

[0053] In one preferred embodiment, the sliding device 5 can also adopt a sliding rod part and a linkage hinged part. A sliding groove is provided on the inclined rod. The sliding rod part is used for sliding cooperation with the sliding groove, and the linkage hinged part is used for hinged cooperation with the linkage rod. The sliding rod part can be combined with a pulley design or a T-shaped rod design to facilitate cooperation with the sliding groove. The sliding groove is usually a long strip hole structure, and its purpose is to guide and stabilize the linkage rod.

[0054] In one preferred embodiment, the sliding device 5 can also adopt a sliding trolley with the inclined rod 6 as a track. The structure of the sliding trolley is usually a single or two pulleys combined with a base, which is a common technology in the field of slide rails in the prior art, and its structure can also be adjusted according to requirements, which will not be elaborated here.

[0055] Combined with the drawings, in one preferred embodiment, the outer end of the linkage rod 8 is hinged to the cornice rod 3, and the sliding device 5 is hinged to the outer end of the linkage rod 8. Preferably, the hinged part of the linkage rod 8 and the cornice rod 3 and the hinged part of the sliding device 5 and the linkage rod 8 are respectively located on both sides of the linkage rod 8. Usually, the hinged part of the sliding device 5 and the linkage rod 8 is close to the inclined rod 6. This design integrates multiple hinge points into one place, making its structure more concise and having better aesthetic appearance.

[0056] With reference to the drawings, in one preferred embodiment, the outer end of the linkage rod 8 is hinged to the cornice rod 3, and the sliding device 5 is hinged to the middle of the linkage rod 8. The hinged position of the sliding device 5 and the linkage rod 8 is usually close to the end of the linkage rod 8, showing a split design, which can improve the smoothness of the transmission of the linkage rod 8, and can increase the error tolerance of the movement of the linkage rod 8, and improve the stability and smoothness of the transmission of the linkage rod 8.

[0057] With reference to the drawings, in one preferred embodiment, the middle of the linkage rod 8 is hinged to the cornice rod 3, and the sliding device 5 is hinged to the outer end of the linkage rod 8. When the cornice rod 3 is preferably in a straight rod state, this structural design is usually adopted to meet the design requirements for cornice rods 3 of different specifications.

[0058] In one preferred embodiment, the linkage rod 8 has a long strip thin plate structure. By adopting this structural feature, interference between the linkage rod 8 and components such as the diagonal rod 3 and the tent support rod 2 can be avoided, and at the same time, the volume can be reduced, and the overall packaging size of the folding tent can be reduced.

[0059] Through optimized design, the present invention uses the linkage rod as a linkage component, and uses the extension of the tent support rod to drive the extension of the linkage rod, thereby driving the cornice rod to complete the extension; compared with the prior art in which the sliding seat is used to drive the diagonal rod to slide, and then the connecting seat is used to drive the cornice rod, the power transmission of the present invention is more direct and effective, making the extension or contraction of the cornice rod smoother; by using the restriction of the linkage rod on the cornice rod and combining with the cornice sleeve, the installation of the cornice rod is more stable; by selecting the hinged position of the cornice rod and the linkage rod, the length dimension of the cornice rod is adjustable and the applicability is stronger.

[0060] As is known by technical common sense, the present invention can be implemented by other embodiments that do not depart from its spirit or essential features. Therefore, the above-disclosed embodiments are illustrative in all aspects and not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are encompassed by the present invention.
