The application claims priority to Chinese patent application No. 202322076333X, filed on Aug. 3, 2023, the entire contents of which are incorporated herein by reference.
This application involves the technical field of canopies, in particular to a one-push instant canopy frame.
With the development of outdoor activities, the demand for canopies is becoming increasingly frequent. With the improvement of living standards, foldable canopies are becoming more and more widely used. The current canopy consists of foldable canopy frame and tarpaulins. A foldable canopy frame is composed of a roof frame and four or more supporting legs. In order for the canopy to maintain its unfolded state, a locking structure is often installed on the support legs to lock the canopy. This locking structure is quite cumbersome as it requires the user to perform locking or unlocking operations on each supporting leg during the process of unfolding or folding the canopy. If forgotten, it can also lead to functional defects or the misoperation of forced unlocking. In addition, it requires multiple persons to support the canopy together when it is being folded or unfolded.
In order to simplify the locking operation, there is a locking structure installed on the middle support member of the roof frame of canopy on the market, such as patent authorization announcement No. CN109667467A, named “a foldable canopy with self-locking central lock”. This self-locking central lock consists of a central top cover, a bottom cover, at least two top pipes that are pivotally connected with the central top cove, and at least two connecting rods. Each connecting rod is pivotally connected with a top pipe at its pivot and with the bottom cover at its pivot. The self-locking central lock is set at the locking position by the upward movement of the bottom cover and at least two connecting rods. The self-locking central lock moves to the locking position under the following conditions when the bottom cover is pushed upwards.
On one hand, this structure requires the user to push the self-locking central lock upwards until the bottom cover pivot is higher than the top pipe pivot, that is, the angle formed by the two connecting rods exceeds 180°. It means you have to push the self-locking central lock upwards to a certain height that is infinitely approaching the central top cover. Therefore, the user may not be tall enough to lock the self-locking central lock. What's more, it is troublesome to pull down this leap-type structure. On the other hand, the locking device is set on the central top cover, so when using the self-locking central lock and the locking device for locking, it is necessary to calibrate the locking position of the self-locking central lock and the locking device. The user is unable to calibrate the lock as his/her bottom-up operations are restricted by blind spots. It is easy to encounter situations where the self-locking central lock cannot adapt to the locking device.
In view of the practical problems and technical shortcomings mentioned above, this utility model provides a one-push instant canopy frame that can be quickly locked to an unfolded state and pulled down to a folded state.
In order to solve the above technical problems, this application provides a one-push instant canopy frame that puts forward the following technical solutions:
A one-push instant canopy frame consists of several support columns, several outward telescopic units, and multiple inward telescopic units. One outward telescopic unit is pivotally connected between two adjacent support columns. One support column is pivotally connected to one inward telescopic unit. The outward telescopic units and inward telescopic units constitute the top frame of the canopy. A push locking device is set at the lower end of the central top cover of the top frame.
The push locking device consists of a push member and a locking member. The push member is pivotally connected with the inward telescopic unit, and equipped with a central rod. The locking member is slidably connected with the central rod. The locking member is used to lock the canopy in an unfolded state, and allows the canopy to be folded when the locking member is unlocked.
During the unfolding process, an external force acts on the locking member to drive the push member to unfold the canopy, the locking member slides on the central rod, and the locking member is in an unlocked state. When the push member is pushed to a certain height, the locking member will slide to a locked state.
In a preferred embodiment, the push member consists of a top cover and two or more push rods. The top cover is fixed at the upper end of the central rod.

This application is further described in detail in combination with the
This embodiment makes public a one-push instant canopy frame that consists of several support columns 2, several outward telescopic units 3, and multiple inward telescopic units 4; One outward telescopic unit 3 is pivotally connected between two adjacent support columns 2. One support column 2 is pivotally connected to one inward telescopic unit 4; The outward telescopic units 3 and inward telescopic units 4 constitute the top frame of the canopy; A push locking device 1 is set at the lower end of the central top cover 112 of the top frame. The top push locking device 1 is used to lock the foldable canopy to an unfolded state when the top push locking device 1 is locked, and allows the canopy to be folded when the push locking device 1 is unlocked. The inner end of the inward telescopic unit 4 is connected with the push locking device 1.
In particular, the inward telescopic unit 4 consists four connecting rods that are pivotally connected with one another, one end of which is pivotally connected with the support column 2. The outward telescopic unit 3 is a folding frame that is pivotally connected between two support columns 2. The folding frame consists at least two scissor-shaped connecting rods that are pivotally connected. Pivotal connection means that both the upper and lower ends of two adjacent connecting rods are pivotally connected. The folding frame has four outer ends. A fixed seat is set at the top of the support column 2. There is a sliding seat that can slide up and down along the support column 2. The four outer ends are respectively pivotally connected with the fixed and sliding seats on the adjacent two supporting columns 2. You may refer to the structures of existing canopies for the structure of this canopy.
In this embodiment, the push locking device 1 consists of a push member 11 and a locking member 12. The push member 11 is pivotally connected with the inward telescopic unit 4. The push member 11 is equipped with a central rod 111. The locking member 12 is slidably connected with the central rod 111; The locking member 12 is used to lock the canopy in an unfolded state, and allows the canopy to be folded when the locking member is unlocked.
In particular, during the unfolding process, an external force acts on the locking member 12 to drive the push member 11 to unfold the canopy, the locking member 12 slides on the central rod 111, and the locking member 12 is in an unlocked state; When the push member 11 is pushed to a certain height, the locking member 12 will slide to a locked state.
It should be noted that the height reached by the push member 11 is lower than the connection position between the inner end of the inward telescopic unit 4 and the push locking device 1. The height reached by the push member 11 does not go beyond the connection position, so that the connection between the push member 11 and the inward telescopic unit 4 remains always inclined downward for easy folding.
In this embodiment, the push member 11 further consists of a top cover 112 and four push rods 113. The top cover 112 is fixed at the upper end of the central rod 111. One end of the push rod 113 is pivotally connected with the top cover 112; The other end is pivotally connected with the inward telescopic unit 4 by the middle part of one of the four connecting rods that are pivotally connected with one another. This middle part refers to any part between the two ends, preferably ¼-¾, or ⅓-⅔.
In this embodiment, the locking member 12 consists of a sliding rod 121 and four support rods 122; One end of the support rod 122 is pivotally connected with the sliding rod 121, and the other end is pivotally connected with the middle part of the push rod 113. This middle part refers to any part between the two ends, preferably ¼-¾, or ⅓-⅔.
A stopping member 114 is set between the sliding rod 121 and the central rod 111. When the top cover 112 is pushed up to the pivot end between the push rod 113 and the inward telescopic unit 4 and below the pivot end, and the upward movement of the sliding rod 121 and support rods 122 is stopped by the stopping member 114, the locking member 12 will move to the locking position.
In particular, during the unfolding process, an external force acts on the sliding rod 121 to make it move upwards on the central rod 111. The upward movement of the sliding rod 121 pushes the support rod 122 and the push rod 113 upwards. The upward movement of the push rod 113 acts on the inward telescopic unit 4 that is pivotally connected with it. The push rod 113 moves upwards to push the central rod 111 upwards. Therefore, during the unfolding process, the central rod 111 and the sliding rod 121 push each other within a certain sliding amount, and speed of central rod 111 is less than that of sliding rod 121. During the unfolding process, the locking member 12 is in an unlocked state; When the push member 11 is pushed to a certain height, the speed of the sliding rod 121 is faster, so the sliding rod 121 will slide to the locking member 12 to the locked state.
To fold the canopy, unlock the locking member 12, pull down the sliding rod 121, and drive the support rod 122 to pull down the push rod 113, which will pull down the inward telescopic unit 4. As the connection between the push member 11 and the inward telescopic unit 4 maintain always inclined downward, it will be easy to pull down the inward telescopic unit 4.
In this embodiment, in order to facilitate the folding and locking of the canopy, the locking member 12 consists of a sliding rod 121 and at least two support rods 122; One end of the support rod 122 is pivotally connected with the sliding rod 121, while the other end is pivotally connected with the push rod 113; A stopping member 114 is set between the sliding rod 121 and the central rod 111. When the top cover 112 is pushed up to the pivot end between the push rod 113 and the inward telescopic unit 4 and below the pivot end, and the upward movement of the sliding rod 121 and support rods 122 is stopped by the stopping member 114, the locking member 12 will move to the locking position.
In particular, the central rod 111 is equipped with a housing chamber for installing the stopping member 114. The sliding rod 121 is provided with at least one limiting hole 123; The sliding rod 121 moves up and down along the central rod 111. The stopping member 114 is placed in the housing chamber or the limiting hole 123. The housing chamber consists of an opening that is opposite to or staggered with the limiting hole 123. When the opening is opposite to the limiting hole 123, the stopping member 114 is placed in the limiting hole 123.
An unlocking member 124 is set at the position corresponding to the limiting hole 123 on the sliding rod 121. The unlocking member 124 acts inward on the stopping member 114 to place the stopping member 114 in the housing chamber. The stopping member 114 is a pin with a certain elasticity; The unlocking member 124 is a button. During the unfolding process of the canopy, push the sliding rod 121 upwards until the limiting hole 123 of the sliding rod 121 corresponds to the opening of the central rod 111. In this case, the stopping member 114 inserts the pin into the limiting hole 123 under elastic action to limit it, thereby locking the unfolded state of the canopy. During the folding process of the canopy, press the unlocking member 124 inward to squeeze the stopping member 114, and then the stopping member 114 overcomes the elastic to recover the pin to the housing chamber under the action of an external force, thereby releasing the limit on the limiting hole 123. In this case, the sliding rod 121 can move relative to the central rod 111, and pull down the sliding rod 121 to completes the folding of the canopy.
The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, any equivalent change that is made based on the structures, shapes, and principles specified in this application shall be covered within the scope of protection of this application.
