Push-pull type shed cover

Abstract

In order to overcome the defects that door type frame columns and trundles of an existing product are too many, the distance between the columns is too small, and four-direction passing under a shed is affected, a single movable stand column is arranged below the front portion of each row of connecting rod push-pull assembly composed of shear supporting rods, and the side edge of a top shielding plate is directly connected between the upper half sections of the shear supporting rods; the overall overhead shed cover supported only by the four corners is formed, and people and vehicles can pass through the spacious space among the stand columns at the four corners. Due to the fact that four directions are through, the shed cover can be used in a combined mode in rows and columns in the longitudinal and transverse directions, a large shed space capable of being rapidly folded and unfolded in an ultra-long and ultra-large field is formed, the structure is simple, the application mode is flexible, and the operation efficiency is high.

Description

Technical Field

[0001] The invention relates to a canopy cover, and in particular to a push-pull type canopy cover which can be pushed and pulled horizontally to be telescopically deformed. Background Art

[0002] Existing push-pull shed products are widely used Fig.23 The movable portal frame column with column base pulleys connected in series by scissor-type connecting rods is shown and covered with a rainproof cloth.

[0003] The main drawbacks of this product are:

[0004] 1. There are many portal frame columns with a large number of columns and a small distance between columns, which affects the passage of people and vehicles, restricts the space layout under the shed, and makes it difficult to form a spacious four-way passage space under the shed cover;

[0005] 2. Because the number of shear rod sliding rings and casters of the portal frame column is large, the push-pull resistance of the shed cover is large and the overall noise is large;

[0006] 3. Because it is difficult to ensure the flatness of the ground at the installation site, when the portal frame column is pushed and pulled, the numerous casters will fluctuate during movement, causing the entire shed to shake, affecting the user experience. Summary of the invention

[0007] In order to solve the above-mentioned defects of the prior art, the present invention proposes a push-pull type canopy cover, which is characterized by:

[0008] It includes a row of connecting rod push-pull assemblies arranged on the left and a row of connecting rod push-pull assemblies arranged on the right;

[0009] The connecting rod push-pull assembly is composed of an overhead shear strut rod 1;

[0010] The shear strut rods 1 in each row of the connecting rod push-pull assembly include a plurality of forward-leaning shear strut rods 1-2 and a plurality of backward-leaning shear strut rods 1-1;

[0011] Each forward-leaning shear brace rod 1-2 in each row of connecting rod push-pull assemblies is hinged to the middle of the backward-leaning shear brace rod 1-1 at the corresponding position;

[0012] The bottom of the forward-leaning shear brace rod 1-2 in each row of the connecting rod push-pull assembly is hinged to the bottom of the rearward-leaning shear brace rod 1-1 adjacent to the rear;

[0013] The top of the backward-leaning shear brace rod 1-1 in each row of the connecting rod push-pull assembly is hinged to the top of the forward-leaning shear brace rod 1-2 adjacent to the rear;

[0014] There are multiple parallel top shields 3 between the two rows of connecting rod push-pull assemblies, including multiple forward-inclined top shields 3-2 and multiple backward-inclined top shields 3-1.

[0015] The two side edges of each forward-inclined top shield 3-2 are connected to the side surfaces of the upper half structures of two forward-inclined shear struts 1-2 located at corresponding positions in two rows of push-pull assemblies;

[0016] The two side edges of each rearward-inclined top shield 3-1 are connected to the side surfaces of the upper half structures of two rearward-inclined shear struts 1-1 respectively located at corresponding positions in two rows of push-pull assemblies;

[0017] A movable support 2-1 with a caster 21 at the bottom is provided at the front position of each row of connecting rod push-pull assemblies; the top of each movable support 2-1 is hinged to the top of a forward-leaning shearing strut 1-2a adjacent to the rear;

[0018] A longitudinal guide rail 22 is provided just below the hinge shaft at the top end of the movable pillar 2-1. A guide wheel 6 is installed inside the longitudinal guide rail 22. The guide wheel 6 is hinged to the bottom end of a rearward-leaning shearing strut 1-1a located at the rear side of the movable pillar 2-1.

[0019] A support body is provided at the rear position of each row of connecting rod push-pull assemblies; the top end of the support body is hinged to the top end of a rearward inclined shear brace rod 1-1b adjacent to the front;

[0020] A longitudinal guide rail 22 with a built-in guide wheel 6 is provided directly below the hinge shaft at the top end of the support body. The guide wheel 6 is hinged to the bottom end of a forward-leaning shear strut 1-2b located in front of the support body.

[0021] Preferably,

[0022] The front of the movable pillar 2-1 in each row of the connecting rod push-pull assembly is provided with a column front forward tilting shear strut 1-3 and a column front and rear tilting connecting rod 4;

[0023] The guide wheel 6 is hinged to the bottom end of the shear brace rod 1-3 in front of the column;

[0024] The middle part of the column front forward tilt shear strut 1-3 is hinged to the bottom end of the column front and rear tilt connecting rod 4, and the top end of the column front and rear tilt connecting rod 4 is hinged to the top end of the movable support 2-1;

[0025] A column front tilt top shield plate 3-11 and a column front tilt top shield plate 3-21 are provided between the two rows of connecting rod push-pull assemblies. The two side edges of the column front tilt top shield plate 3-11 are respectively connected to the side edges of the two column front tilt connecting rods 4; the two side edges of the column front tilt top shield plate 3-21 are respectively connected to the two column front tilt shear struts 1-3.

[0026] Preferably,

[0027] The left side of the upper half of the forward-leaning shearing brace rod 1-2 in the connecting rod push-pull assembly arranged on the left and the right side of the upper half of the forward-leaning shearing brace rod 1-2 in the connecting rod push-pull assembly arranged on the right are connected to the side of the forward-leaning top shield plate 3-31;

[0028] The left side of the upper half of the backward tilting shear strut rod 1-1 in the connecting rod push-pull assembly arranged on the left and the right side of the upper half of the backward tilting shear strut rod 1-1 in the connecting rod push-pull assembly arranged on the right are connected to the side of the side extending backward tilting top shield plate 3-32.

[0029] Preferably,

[0030] The upper part of one of the movable pillars 2 - 1 in one row of the push-pull assemblies is connected to the upper part of one of the movable pillars 2 - 1 in another row of the push-pull assemblies via a pillar truss 5 .

[0031] Preferably,

[0032] There are bendable connecting strips 7 between the top edges of each of the top shields 3. When each row of connecting rod push-pull assemblies is stretched to a preset limit length, each connecting strip 7 is flattened.

[0033] Compared with the prior art, the present invention can only set four corner pillars to support the canopy, significantly expanding the distance between the pillars, so that the canopy has wide openings in the front, back, left and right directions, allowing people and vehicles to pass through easily, thereby significantly improving the layout conditions of the space under the canopy, allowing the product to be more flexibly used in a variety of occasions. Because the number of movable columns can be reduced to only 2, the caster noise is significantly reduced. Because a unit can have only two casters, under controllable cost conditions, the casters can be selected with a larger diameter. During the movement process, the larger diameter casters will cause more gentle vibrations to the upper structure and the overall noise will be smaller.

[0034] In this article, the term "support body" can be a movable column with casters, a stationary column or a stationary body such as a fixed column fixed to the ground, or a building body, such as a wall.

[0035] In this document, the term "connecting strip" may be a flexible rope, a chain, a flexible sheet with a foldable middle portion, or a connecting rod with bendable hinge structures in the middle and at the ends.

[0036] In this article, the term "roof shield" can be a rigid board or a truss frame with a covering on the surface. This covering can be a flexible thin material, such as tarpaulin, canvas, plastic sheeting, or a rigid board, such as a solar panel, explosion-proof panel, glass panel, photovoltaic panel.

[0037] In this article, the directional terms "left, right, front, and back" refer to the left, right, front, and back directions of the observer when the observer is outside between the moving pillars and observes the direction of the canopy;

[0038] The above orientation terms are only intended to facilitate accurate description of the relative positional relationship of the various parts of the present invention, rather than indicating or implying that the referred feature objects must have a specific orientation, or must be combined and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0039] More specific technical features and beneficial effects of the present invention will be further described in detail in the following embodiments in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0069] Embodiment 1 of the present invention is as Figures 1 to 8 shown.

[0070] The push-pull canopy comprises two rows of overhead connecting rod push-pull assemblies on the left and right sides. Each row of connecting rod push-pull assemblies comprises four forward-leaning shear braces 1-2 and four backward-leaning shear braces 1-1. Figure 1 , Figure 2 The push-pull canopy is shown in a fully unfolded state.

[0071] See also Figure 3 In the same row of connecting rod push-pull assemblies, each forward-leaning shear strut rod 1-2 is hinged to the middle of the backward-leaning shear strut rod 1-1 at the corresponding position by a hinge shaft 11; the bottom of the forward-leaning shear strut rod 1-2 is hinged to the bottom of the rearward-leaning shear strut rod 1-1 adjacent to the rear by a hinge shaft 11; the top of the backward-leaning shear strut rod 1-1 is hinged to the top of the forward-leaning shear strut rod 1-2 adjacent to the rear by a hinge shaft 11.

[0072] In order to save the width space occupied by the shear brace, Figure 3 As shown, the middle part of the forward-leaning shear strut 1-2 and the middle part of the backward-leaning shear strut 1-1 are hinged to each other by special-shaped nested joints.

[0073] See also Figure 4 The front end of each row of connecting rod push-pull assemblies is provided with a movable support 2-1 with a caster 21 at the bottom end; the top end of each movable support 2-1 is hinged to the top end of the frontmost forward inclined shear support rod 1-2a of each row of connecting rod push-pull assemblies by a hinge shaft 11;

[0074] A grooved longitudinal guide rail 22 is provided on the side of the lower half of the movable support 2-1, and a guide wheel 6 is installed inside the longitudinal guide rail 22. The guide wheel 6 is hinged to the bottom end of the frontmost rearward shearing strut rod 1-1a of each row of connecting rod push-pull assemblies by a hinge shaft 11;

[0075] A stationary support 2-2 is provided at the rear end of each row of connecting rod push-pull assemblies; the top end of the stationary support 2-2 is hinged to the top end of the last rearward inclined shear support rod 1-1b of each row of connecting rod push-pull assemblies by a hinge shaft 11;

[0076] A grooved longitudinal guide rail 22 is provided on the side of the lower half of the stationary support 2-2, and a guide wheel 6 is installed inside the longitudinal guide rail 22. The guide wheel 6 is hinged to the bottom end of the last forward-leaning shear strut rod 1-2b of each row of connecting rod push-pull assemblies by a hinge shaft 11.

[0077] See also Figure 1 , Figure 5 , Figure 6 Between the two rows of connecting rod push-pull assemblies, there are four forward-inclined top shields 3-2 and four backward-inclined top shields 3-1 that are parallel to each other and alternately arranged.

[0078] The two side edges of each forward-inclined top shield plate 3-2 are connected to the corresponding sides of the upper half structures of two forward-inclined shear struts 1-2 respectively located at corresponding positions in the two rows of push-pull assemblies.

[0079] The two side edges of each rearward-inclined top shield 3-1 are connected to the corresponding sides of the upper half structures of two rearward-inclined shear struts 1-1 respectively located at corresponding positions in two rows of push-pull assemblies.

[0080] See also Figure 6 When the two rows of connecting rod push-pull assemblies are pushed, pulled, and retracted synchronously, each top shield 3 is also folded and extended synchronously.

[0081] In order to enhance the strength and stability of each support, the upper parts of the two movable supports 2 - 1 and the upper parts of the two stationary supports 2 - 2 are rigidly connected to each other via a support truss 5 .

[0082] When the automatic telescopic function is required, a simple means is obviously to install hub motors that can operate synchronously on the two casters 21 of the mobile support 2-1.

[0083] When the ground flatness of the site does not meet the requirements, a rigid driving wheel with a guide rim can be used and two ground rails can be set on the ground.

[0084] See also Figure 7 , Figure 8 In order to keep the center of gravity stable and prevent tipping after being fully retracted and folded, the bottom of the stationary support 2-2 can be rigidly fixed to the ground with fasteners.

[0085] Obviously, in some occasions, in order to allow the canopy cover to move freely horizontally as a whole, the stationary support 2-2 can also be replaced with a movable support 2-1 with casters 21.

[0086] Obviously, a suitable locking mechanism may be used to lock the position when the canopy cover is fully extended or fully retracted.

[0087] Example 2 Figures 9 to 13 , Fig.21 shown.

[0088] See also Fig. 9 , Fig.10 , Fig.11 On the basis of Example 1, the front of the two movable pillars 2-1 of this embodiment are provided with a column front forward tilting shear strut 1-3 and a column front and rear tilting connecting rod 4; the length of the column front and rear tilting connecting rod 4 is about half of the column front forward tilting shear strut 1-3.

[0089] The guide wheel 6 axis installed on the movable pillar 2-1 is hinged to the bottom end of the column front shear strut 1-3; the middle part of the column front forward tilting shear strut 1-3 is hinged to the bottom end of the column front and rear tilting connecting rod 4, and the top end of the column front and rear tilting connecting rod 4 is hinged to the top end of the movable pillar 2-1.

[0090] A column front forward tilting top shield plate 3-21 is installed between the corresponding sides of the upper half of the two column front forward tilting shear struts 1-3, and a column front forward tilting top shield plate 3-11 is installed between the corresponding sides of the two column front and rear tilting connecting rods 4.

[0091] In order to enhance the strength of the column-front forward-inclined top shield 3-21 and optimize the appearance, a column-front forward-inclined top shield front hanging plate 3-211 may also be provided on the front side of the top edge of the column-front forward-inclined top shield 3-21.

[0092] See also Fig.12 , Fig.13 , Fig.14 When the canopy cover is pushed and pulled to be retracted, the column front and rear inclined top shielding plate 3-11 and the column front forward inclined top shielding plate 3-21 will also be retracted and extended synchronously.

[0093] The function of the column front and rear inclined top shielding plate 3-11 and the column front inclined top shielding plate 3-21 is to extend the effective shielding space of the canopy to the front side of the movable support 2-1 and increase the overall depth of the canopy. Fig.21 When applied to a carport, the relatively backward-moving movable support 2-1 is beneficial to the turning and reversing operation of vehicles on the ground under the carport.

[0094] Example 3 Fig.15 , Fig.16 shown.

[0095] Connecting multiple embodiments 3 side by side and sharing the support pillars will form a Fig.15 Since the adjacent units of this embodiment share the movable pillars 2-1 and the stationary pillars 2-2, in order to reduce the difficulty of operation, a synchronous motor can be used to drive the casters 21 of the movable pillars of each unit to complete the synchronous automatic extension and contraction of the row of units.

[0096] Example 4 Fig.17 , Fig.18 shown.

[0097] In order to enhance the stability of the canopy structure during operation and improve the wind resistance, bendable connecting strips 7 are provided between the top edges of each top shield plate 3. When the canopy is extended to a preset limit length, each connecting strip 7 is flattened. In this embodiment, each connecting strip is two sections of steel strips hinged in the middle, and the outer ends of the steel strips are hinged to the top edge of the top shield plate 3. Fig.18 When the canopy cover is retracted, the middle part of the connecting strip 7 naturally sinks and bends, and is finally hidden in the gap between the adjacent top shielding plates 3.

[0098] Example 5 Fig.19 shown.

[0099] On the basis of Example 2, in order to further expand the shielding space on the left and right outer sides of the shed cover, this embodiment installs side-extending forward-inclined top shielding plates 3-31 on the left side of the upper half of the four forward-inclined shear struts 1-2 in the connecting rod push-pull assembly arranged on the left and on the right side of the upper half of the forward-inclined shear struts 1-2 in the connecting rod push-pull assembly arranged on the right;

[0100] The side-extended rearward-tilted top shield plates 3-32 are respectively installed on the left side of the upper half of the four rearward-tilted shear struts 1-1 in the connecting rod push-pull assembly arranged on the left and on the right side of the upper half of the rearward-tilted shear struts 1-1 in the connecting rod push-pull assembly arranged on the right.

[0101] This embodiment is particularly suitable for applications where the shielding space needs to be extended outside the pillar. For example, when the pillar is near a river, in order to expand the shielding space above the water surface, the present embodiment mode can be used for operation.

[0102] Example 6 Fig. 20 , Fig.21 shown.

[0103] In this embodiment, two sets of embodiment 2 are connected in reverse and share the static support 2-2, so that the canopy shielding space is doubled with only 6 supports. When performing the extension or contraction operation, the two pairs of movable supports 2-1 move in reverse. Fig.21 When the embodiment is in a fully retracted state, the ground area occupied is very small.
