Description

Technical Field

[0001] The present application relates to a barrier, and more particularly, to a barrier with an adjustable and stable width range. Background Art

[0002] Barriers are well known; generally, a barrier includes a pivot member that is held between two fixed members to pivot on one of the two fixed members. The two fixed members are fastened against the walls on either side of an opening. The pivot member can prevent passage between the fixed members when pivoted to a closed position between the fixed members, or allow passage between the fixed members when pivoted away from the other of the fixed members. Generally, the barrier is sized to prevent children, typically toddlers (starting from about 1 year old to 3 years old), from passing through.

[0003] Specifically, such barriers are often used to prevent access to stairs, or to prevent children from falling down the stairs at the top of the stairs, or to prevent a child from climbing up the stairs and then falling at the bottom. In this case, the barrier can be used as a stair gate or a baby gate. Such a gate can also be used to confine a domestic pet to a desired area.

[0004] The size of the opening that is desired to be selectively blocked by a given barrier can vary because there is no standard width for stairs or other openings. Thus, the barrier should be able to accommodate a variety of opening widths, and prior art barriers have addressed this problem. However, for application to larger width openings, the required longer pivot members are prone to deviation in the length direction during installation, resulting in an inability to engage with the fixed members stably as expected.

[0019] In order to make the technical problems to be solved, technical solutions and beneficial effects of the present application more clearly understood, the following further details the present application in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0020] Figure 1 An exemplary barrier 10 of the embodiment of the present application is shown. This embodiment relates to a barrier whose structural components can be formed of metal, but obviously this embodiment can be used for other materials, such as wood.

[0021] The barrier 10 includes a first fixing member 12, a second fixing member 14, and a pivot member 16. The pivot member 16 is pivotally mounted on the first fixing member 12 and can be engaged with the second fixing member 14. The first fixing member 12 and the second fixing member 14 can generally be fixed to either side of the wall or the stair frame of the opening 70 where passage is to be blocked.

[0022] The barrier 10 has a closed position and an open position (not shown). In the closed position, the pivot member 16 blocks passage between the first fixing member 12 and the second fixing member 14; in the open position, the pivot member 16 pivots away from the second fixing member 14 to allow passage between the first fixing member 12 and the second fixing member 14.

[0023] In order to allow for openings of different sizes, i.e., gaps of different sizes between walls or stair frames (i.e., between the first fixing member 12 and the second fixing member 14), the pivot member 16 is formed by parallel first width members 20 and second width members 22, which can be rigidly fastened together at any point within a continuous range 26 by a fastening mechanism 24; the range 26 is Figure 1 Shown in FIG. 2 are a range of positions that the fastening mechanism 24 can assume on the first width member 20 .

[0024] Each of the first width member 20 and the second width member 22 includes a generally flat rectangular body, the rectangular body of the first width member 20 having a frame member 30 surrounding the rod 28, and the rectangular body of the second width member 22 having a frame member 31 surrounding the rod 29. The spacing between the rods 28 and 29 is sufficiently fine to prevent a child from passing therethrough. The frame members 30 and 31 may be tubular and rectangular in cross section.

[0025] Thus, in effect, the first width members 20, 22 allow the pivot component 16 to continuously fold from a shorter length where the first width members 20, 22 overlap substantially to a longer length where the first width members 20, 22 overlap less substantially.

[0026] The upper latch receiver 32 is fixed to the upper end of the second fixed part 14, and the upper latch 34 is fixed to the second width member 22 of the pivoting part 16. The upper latch 34 includes a first latch pin 36 extending along the length direction L of the barrier 10 and being telescopically slidable. The upper latch receiver 32 is provided with a first slot 38 for receiving the first latch pin 36. When the pivoting part 16 is located at a position where the first latch pin 36 faces the first slot 38, the first latch pin 36 can slide into or out of the first slot 38, thereby achieving the locking or release of the upper latch 34 and the upper latch receiver 32. The upper latch receiver 32 includes a pair of first inclined surfaces 40 located on both sides of the first slot 38 and guiding the first slot 38. When the pivoting part 16 is pivoted closed, the first latch pin 36 may hit one of the two first inclined surfaces 40, which causes the first latch pin 36 to retract. Then, as the pivoting part 16 continues to pivot toward the closed position, the first latch pin 36 will spring into the first slot 38.

[0027] The lower latch receiver 42 is fixed to the lower end of the second fixed member 14. The lower latch 44 is fixed to the second width member 22 of the pivot member 16. The lower latch 44 includes a second bolt 46 that extends along the height direction H of the barrier 10 and is telescopically slidable. The lower latch receiver 42 is provided with a second slot 48 for receiving the second bolt 46. When the pivot member 16 is in a position where the second bolt 46 faces the second slot 48, the second bolt 46 can be received in the second slot 48 to achieve the locking of the lower latch 44 and the lower latch receiver 42. The pivot member 16 can be lifted by an external force to make the second bolt 46 leave the second slot 48 to achieve the release of the lower latch 44 and the lower latch receiver 42. The lower latch receiver 42 includes a pair of second inclined surfaces 50 located on both sides of the second slot 48 for guiding the second slot 48. When the pivot member 16 pivots to close, the second bolt 46 may strike one of the two second inclined surfaces 50, which causes the second bolt 48 to retract upward. Then, as the pivot member 16 continues to pivot toward the closed position, the second bolt 46 will snap into the second slot 48. Therefore, when the pivot member 16 is closed, the first bolt 36 is inserted into the first slot 38, and at the same time, the second bolt 46 is inserted into the second slot 48, forming a double anchoring to enhance safety. Only when the first bolt 36 leaves the first slot 38 can the pivot member 16 be lifted to make the second bolt 46 leave the second slot 48. The telescopic sliding of the first bolt 36 and the second bolt 46 can be achieved by springs.

[0028] In the barriers in the prior art, the bolt of the lower latch usually extends along the length direction of the barrier. Due to the deviation in the length direction caused by some parts not being properly installed during user installation, it often occurs that the upper latch and the upper latch receiver have been engaged, but the lower latch cannot be engaged with the lower latch receiver. This is manifested as a gap between the bolt of the lower latch and the slot of the lower latch receiver, which makes the anchoring function of the lower latch unable to play. The barrier 10 of the embodiment of the present application can avoid this situation because in the embodiment of the present application, the second bolt 46 of the lower latch 44 extends along the height direction H, which enables the second slot 48 to have an additional dimension of margin part 51 extending in the length direction L during design. The position where the second bolt 46 is located in the figure is the position when the barrier 10 is installed without deviation. The margin part 51 is the part where the second slot 48 extends from the position where the second bolt 46 is located to its free end. When there is a deviation in the length direction during the installation of the barrier 10, the second bolt 46 can also be captured or received by the margin part 51. The second slot 48 has a proximal end adjacent to the second fixing member 14 and an opposite distal end, and the distal end has an open port 53, which enables the second bolt 46 to play an anchoring role even if only part of it is located within the port 53 due to the deviation. The length of the margin part 51 is usually related to the longest length of the pivot member 16. Because the longer the length of the pivot member 16, the more likely it is to have a deviation and the greater the deviation will be. Therefore, when designing, the longer the length of the pivot member 16, the larger the length of the margin part 51 is usually set.

[0029] The upper pivot seat 52 is fixed to the upper end of the first fixing member 12, and the upper rotating element 54 is fixed to the first width member 20 of the pivot member 16. The upper rotating element 54 is pivotally connected to the upper pivot seat 52. The upper pivot seat 52 has a lower side adjacent to the first width member 20 and a higher opposite side, and a pair of curved surfaces 56 are formed therebetween. The curved surfaces 56 are designed to provide an automatic return function for any angle formed between the upper rotating element 54 and the upper pivot seat 52. The curved surfaces 56 have a first notch 58, a second notch 60, and a third notch 62. The first notch 58 is located at the lowest position, and the second notch 60 and the third notch 62 are spaced apart from the first notch 58 at a selected distance to form a desired movement angle. The upper rotating element 54 has a lug 64 on one side that can move on the curved surface 56. When the pivot member 16 is in the closed position, the lug 64 is held in the lowest first notch 58. When the pivot member 16 pivots to make the lug 64 be held in the second notch 60 or the third notch 62, the pivot member 16 can be held in the open position.

[0030] The lower pivot seat 66 is fixed to the lower end of the first fixing member 12, the lower rotating element 68 is fixed to the first width member 20 of the pivot member 16, and the lower rotating element 68 is pivotally connected to the lower pivot seat 66. The pivot member 16 is pivotally mounted on the first fixing member 12 through the upper rotating element 54 and the lower rotating element 68.

[0031] The part of the barrier 10 other than the second fixing member 14 is pre-assembled (hereinafter referred to as the pre-assembled part). First, the first width member 20 and the second width member 22 are initially loosely connected together by the fastening mechanism 24 to form the pivot member 16, so as to facilitate the user to adjust the overlapping degree of the first width member 20 and the second width member 22 according to needs during installation, thereby adjusting the width of the pivot member 16. Then, the pivot member 16 is initially connected to the first fixing member 12 to form the pre-assembled part.

[0032] The following process is used to install the barrier 10 according to the present disclosure in a door, corridor or stair frame. The pre-assembled part and the second fixing member 14 are taken out of the shipping package. First, the pre-assembled part is installed on one side of the opening 70. Specifically, mounting holes corresponding one by one to the guide holes 72 formed in the first fixing member 12 are pre-drilled on this side, and then a set screw (not shown in the figure) is tightened into the mounting holes along the guide holes 72, so as to fix the first fixing member 12 to this side. It can be understood that the first fixing member 12 is substantially perpendicular to the ground. Then, the second fixing member 14 is installed on the other side of the opening. Specifically, mounting holes corresponding one by one to the guide holes 76 formed in the second fixing member 14 are pre-drilled on this side, and then a set screw (not shown in the figure) is tightened into the mounting holes along the guide holes 76, so as to fix the second fixing member 14 to this side. It can be understood that the second fixing member 14 is substantially perpendicular to the ground and is installed opposite to the first fixing member 12. Finally, the overlapping degree of the first width member 20 and the second width member 22 is adjusted so that the pivot member 16 is engaged with the second fixing member 14 (that is, the first latch 36 is inserted into the first slot 38, and at the same time the second latch 46 is inserted into the second slot 48), and the fastening mechanism 24 fastens the first width member 20 and the second width member 22 together.

[0033] When the width of the opening 70 is relatively large, a pivot member 16 with a correspondingly large width is required. Since the pivot member 16 is usually made of a material with a relatively large weight (such as metal), due to gravity, there is a tendency for the pivot member 16 to be inclined downward from one end adjacent to the first fixing member 12 to the distal end in the length direction, resulting in a deviation in the height direction. This may cause the distal end of the pivot member 16 not to engage with the installed second fixing member 14. To solve this problem, the guiding hole 76 is designed as an elongated hole extending along the height direction H. During installation, the set screw can be loosened, and then the height of the second fixing member 14 can be adjusted so that it can engage with the distal end of the pivot member 16, and then the set screw can be tightened.
