Detailed Description
As shown in fig. 2 and 3, a bed surrounding frame 10 implemented according to the present invention includes a plurality of upright posts 1, a plurality of upper surrounding rod sets 2, a bed bottom supporting rod set 3, a plurality of inclined supporting arms 4, and a plurality of linkage mechanisms 5.
Wherein the column 1 is in contact with the ground at its bottom end. The upper surrounding rod group 2 is respectively pivoted between the upper ends of the upright posts 1.
The upper surrounding rod set 2 comprises a pair of upper surrounding supporting rods 21 pivoted to each other, and can be in a flat state 22 and a folded state 23 by pivoting, and can be extended horizontally to form a polygonal supporting body in the flat state 22, and can be bent downwards to shorten the distance between the upright posts 1 and reduce the space occupied by the surrounding bed framework 10 in the folded state 23.
The bed bottom support rod set 3 is pivotally connected between the lower ends of the columns 1, and at least has a central support seat 31 and a plurality of bed bottom support rods 32, so that the weight can be borne by the contact between the lower end of the central support seat 31 and the ground. Each bed bottom support rod 32 is pivoted with one end and the central support seat 31 and the other end is pivoted with the lower end of a corresponding upright post 1, and a supporting surface of the bed bottom surrounding is formed between the lower end of each upright post 1 and the central support seat 31.
The inclined supporting arm 4 is pivoted between the upright 1 and the corresponding upper surrounding rod set 2, and has a first position 41 for keeping the corresponding upper surrounding rod set 2 in the straight state 22, and a second position 42 for pivoting the corresponding upper surrounding rod set 2 to the folded state 23.
The interlocking mechanisms 5 are respectively arranged in the upright posts 1 and are interlocked between the corresponding bed bottom support rod 32 and the two corresponding inclined support arms 4. When the bed bottom supporting rod set 3 is folded, the upper surrounding rods 2 corresponding to the respective diagonal supporting arms 4 can be changed from the flat state 22 to the folded state 23 by the diagonal supporting arms 4 driven by the linkage of the linkage mechanism 5 through the pivoting of the bed bottom supporting rods 32.
As shown in fig. 2 and 7, an upper pivot base 11 is provided at the upper end of each upright post 1 for pivotally connecting two upper surrounding rod sets 2. For example, each upper pivoting seat 11 may be provided with two guide slots 12 for pivotally connecting two inclined supporting arms 4, and the other end of each of the two inclined supporting arms 4 is pivotally connected to a corresponding upper supporting rod 21.
As shown in fig. 2 to 4, each of the inclined arms 4 may be provided with a pivot point 43 and a second pivot assembly 431. The second pivot assembly 431 is used to pass through the pivot 43 and the guide slot 12 of the upper pivot base 11, and can move up and down along the guide slot 12 by the linkage of the corresponding linkage mechanism 5; when the second pivot assembly 431 is linked by the linking mechanism 5 and moves to the lower end of the guide slot 12, the diagonal bracing arm 4 supports the upper surrounding rod group 2 in the straight state 22; when the second pivot assembly 431 is linked to the upper end of the guide groove 12 by the linking mechanism 5, the inclined supporting arm 4 releases the upper surrounding rod set 2 to pivot the upper surrounding rod set 2 to the folded state 23.
As shown in fig. 7 and 9, the linking mechanism 5 of the present embodiment includes a connecting rod 51 respectively installed in a corresponding upright 1 to move up and down. A transverse groove 52 can be arranged at the upper end of the connecting rod 51 for the second pivot assembly 431 to pass through and pivot with the diagonal arm 4, and the lower end is linked with the corresponding bed bottom support rod 32; thus, when the bed bottom supporting rod set 3 is folded, the connecting rod 51 is moved upward by the pivoting of the bed bottom supporting rod 32, so as to drive the second pivot assembly 431 to move to the upper end of the guiding groove 12, and the upper surrounding rod set 2 corresponding to the diagonal bracing arm 4 is pivoted to the folding state 23.
Preferably, as shown in the embodiment of fig. 7, a curved section 53 is provided at the lower end of the connecting rod 51, and the end of the curved section 53 is pivotally connected to the corresponding bed bottom supporting rod 32. The lower end of each upright post 1 can be respectively provided with a lower pivoting seat 13, and the end of the bed bottom support rod 32 is respectively provided with a rotating member 33, which is pivoted with the lower pivoting seat 13 through the rotating member 33, and is pivoted with the rotating member 33 through the end of the bending section 53. When the bed bottom support rod set 3 is folded, the rotating member 33 can be rotated by the bed bottom support rod 32; thus, when the rotary member 33 is pivoted, the link 51 is driven upward through the curved section 53.
As shown in fig. 8, the curved portion 53 is not necessarily directly pivoted to the rotating member 33, and a link member 54 may be pivoted therebetween. Thus, when the bed bottom supporting rod set 3 is folded, the rotating member 33 pivots along with the bed bottom supporting rod 32, and simultaneously the curved section 53 and the connecting rod 51 move upward through the linkage of the linkage assembly 54, and the second pivot assembly 431 can be driven to move to the upper end of the guide groove 12, so that the upper surrounding rod set 2 corresponding to the diagonal bracing arm 4 pivots to the folding state 23.
The link 51 shown in fig. 7 or 8 may be implemented as a rigid rod or tube, and a metal plate 55 is connected to the upper end, and a transverse groove 52 may be formed on the metal plate 55 to drive the second pivot assembly 431. As shown in fig. 7, a curved section 53 may be formed at the lower end of the shaft, and a long groove 56 may be formed at the end of the curved section 53, and a first pivot assembly 57 is pivotally connected to the corresponding rotary member 33 through the long groove 56. As shown in fig. 8, a pivot hole may be formed at the end of the curved section 53 to be pivotally connected to the corresponding rotary member 33 by a first pivot assembly 57.
As shown in fig. 7 to 10, the folding of the bed surrounding frame 10 of the present invention can be completed only by lifting the central supporting base 31 upward. By pulling up the central support base 31, the bed bottom struts 32 can be pivoted upward to shorten the distance between the upright posts 1, and the linkage mechanisms 5 drive the inclined strut arms 4 to pivot the upper surrounding rod sets 2 corresponding to the inclined strut arms 4 from the straight state 22 to the folded state 23, so that the surrounding bed framework 10 can be folded up and down at the same time.
As shown in FIG. 5, an operating member 36 can be provided on the central support base 31 for the user to grasp and pull up the bed surrounding frame 10. Preferably, the operating member 36 is provided with a slot 360 for the webbing or cloth strip to pass through (not shown), so that the user can fold the bed surrounding frame 10 by pulling up the webbing or cloth strip.
When a child presses the bed bottom supporting rod set 3 in the bed surrounding framework 10, the child cannot fold the bed bottom supporting rod set accidentally, but preferably, a locking mechanism 34 is provided in the central supporting seat 31, and each bed bottom supporting rod 32 cannot pivot relative to the central supporting seat 31 by locking of the locking mechanism 34, so that the bed bottom supporting rod set 3 is kept unfolded and cannot fold accidentally.
When the operating member 36 is pulled upward, the locking state of the locking mechanism 34 is released by actuation, so that each bed bottom support bar 32 can pivot relative to the central support seat 31, and each diagonal arm 4 is driven by each linkage mechanism 5, so that the upper surrounding bar group 2 corresponding to each diagonal arm 4 can pivot from the flat state 22 to the folded state 23, thereby completing the folded state of the surrounding bed framework 10, as shown in fig. 10.
The locking mechanism 34 may include a spring-biased driving member 341, a plurality of spring-biased latching members 342, an operating member 36, and a resilient member 35. The spring-biased driving member 341 is slidably and automatically resettably disposed inside the central supporting seat 31, and is driven by the operating member 36 to stay at a raised position 343 and a lowered position 344.
The operating member 36 of this embodiment is pivoted on the central supporting base 31, and can pivot upward from a horizontal position 361 to abut against the spring-biased driving member 341, and is linked with the spring-biased driving member 341, so that the spring-biased driving member 341 can be abutted by being turned upward when the operating member 36 is pulled, and can move downward from the raised position 343 to the lowered position 344, and each spring-biased buckling assembly 342 can release the limitation on the buckled end of the bed bottom support rod 32.
The spring biased latch assembly 342 is disposed in the central support seat 31 and is linked with the spring biased driving member 341, and automatically latches the end of the bed bottom support rod 32 when the spring biased driving member 341 stays at the rising position 343, so that the latched bed bottom support rod 32 cannot pivot relative to the central support seat 31, and is driven to release the latched end of the bed bottom support rod 32 when the spring biased driving member 341 moves to the falling position 344. When the operating member 36 returns to the horizontal position 361, the spring-biased driving member 341 returns from the lowered position 344 to the raised position 343 by the force of the resilient member 35.
To achieve the purpose of linking the driving member 341, the locking member 342 and the operating member 36, which are biased by a spring, with reference to fig. 5 and 6, a pair of slots 3410 are formed in the spring-biased driving member 341, and each spring-biased latching component 342 is respectively formed with a pivoting portion 3421, a latching portion 3422 and an extending end 3423, which are pivoted in the central supporting base 31 by the pivoting portion 3421, the extended end 3423 is inserted into the slot 3410 to make it swing back and forth with the upward and downward movement of the spring-biased driving member 341, so that the buckling part 3422 buckles the end of the corresponding bed bottom supporting rod 32 when the spring-biased driving member 341 stays at the raised position 343, when the spring-biased driving member 341 stays at the descending position 344, the slot 3410 drives the extending end 3423 to swing the corresponding spring-biased fastening assembly 342, so that the fastening portion 3422 releases the end of the corresponding bed bottom support bar 32.
