Reference will now be made in more detail to embodiments, examples of which are illustrated in the accompanying drawings, in which like reference numerals refer to like elements throughout the document. In this sense, the present embodiments may take different forms and should not be construed as being limited to the descriptions set forth herein. Accordingly, the embodiments are simply described below, with reference to the figures, to explain aspects of the present disclosure. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items. Expressions such as "at least one of", when preceding a list of items, modify the entire list of items and do not modify individual items in the list. Furthermore, the use of "may" when describing embodiments of the present invention refers to "one or more embodiments of the present invention."

Aspects of the present invention will be described in more detail in conjunction with the accompanying drawings.

According to an embodiment that is not part of the present invention, an elastic non-metallic clip (see Figure 2) for the assembly of the fence includes a main body 3 'having an inner wall 3-11 and an outer wall 3 12, wherein a vertical rod insertion hole 3-2 is formed in the middle of the main body 3 'surrounded by the inner wall and extends through the main body 3' from the upper end to the lower end; an outwardly extending flange 3-1 is formed at the upper end of the outer wall of the clip; a section having a top end face 3-3 and an inwardly sloping side face 3-5 that slopes toward the inner wall of the clip from the top edge (intersecting the top end face 3-3) up to the lower edge it is arranged on the outer wall below the flange; a section with two straight walls (for example, a wall extending perpendicular to the top end face of the clip) 3-4 is below the section with the inward sloping face 3-5, and a distance between the two straight walls 3-4 is less than an outer diameter of the outwardly extending flange 3-1 at the upper end; a clamping groove 3-6 is formed between the upper end face 3-3 of the inwardly inclined section 3-5 and the lower end face of the outwardly extending flange 3-1, y matches the thickness of a single wall 10-A of the crossbar 10 (so that a single wall of the crossbar can be inserted and locked with the clamping groove); an inwardly projecting shoulder 3-7 is formed on the inner wall corresponding to the inwardly sloping face 3-5 on the outer wall; and the projection 3-7 extends from the top to the lower in the form of a convex arc. The projection 3-7 is configured to be inserted into a clamping hole 9-1 in the vertical bar 9 (see Figure 4); and the lower end face 3-8 of the shoulder 3-7 is configured to abut against a hole 9-3 of the clamping hole 9-1 in the vertical bar 9. The clip may further include one or more flat side walls 3- 10 (without ribs or sloping side faces) extending vertically from the bottom end face of the outwardly extending flange 3-1. The one or more flat side walls 3-10 can protect the vertical bars from being scratched by the cross bars during fence assembly and can be the same length as well as longer or shorter than the length of the other sections of the clip.

The main body 3 'can be made of plastic or rubber.

The clip may include at least one inwardly sloping face 3-5 on the outer wall below clip flange 3-1 and at least one inwardly projecting shoulder 3-7 on the inner wall. An inwardly sloping face 3-5 on the exterior wall below clip flange 3-1 may be located at a location on the clip side wall corresponding to the location of an inwardly protruding shoulder 3-7 on the inner wall (see figure 2), or it may be located in different places on the side wall. In one example, the clip includes two sections at two oppositely oriented locations, each with an inwardly sloping face 3-5 on the exterior wall below the clip flange 3-1, and a shoulder projecting outward. the interior 3-7 on the interior wall at the location corresponding to the respective inward sloping face 3-5 on the exterior wall. In another example, the clip may include three or more inwardly sloping face sections 3-5 on the exterior wall below clip flange 3-1 and three or more inwardly projecting ribs 3-7 on the interior wall.

The vertical rod insertion hole 3-2 in the middle of the main body 3 'must engage and lock with the vertical rod 9; the outer wall of the main body 3 'must be inserted into the insertion hole (also known as the coupling hole) 10A of the crossbar (see figure 1).

A groove 3-9 is formed in the middle of the shoulder 3-7 on the inner wall of the main body 3 '(see Figure 2); and a tab 9-2 which coincides with the groove 3-9 in the middle of the projection 3-7 is formed in at least one clamping hole 9-1 of the vertical bar 9 (see figure 4).

An assembled fence includes a crossbar 10, a vertical bar 9, and a clip 3 according to previously described embodiments (see Figure 1).

The cross bar 10 may have a plurality of insert holes 10-A spaced along the longitudinal direction corresponding to the number of vertical bars to which it is to be connected. In one example, the cross bar 10 can be a hollow bar having a wall formed of a suitable material. Herein, the hollow crossbar 10 may have a first insertion hole and a second insertion hole facing the first insertion hole in a vertical direction (i.e., vertically aligned with the first insertion hole) to allow the passage of a vertical bar through both during assembly (see figure 1). The thickness of the crossbar wall matches that of the 3-6 clamping groove of the clip. In another example, the crossbar may have only the first insertion hole without the second insertion hole vertically aligned with the first insertion hole. These cross bars are suitable for places where the vertical bars are not intended to pass through the cross bar, such as the highest or lowest cross bar on a fence.

The cross section of the cross bar 10 may be an inverted U shape (see Figure 5). Herein, the insert hole on the side (for example, the upper side) corresponding to the bottom of the U-shape matches the size of the clip, and the opening on the side (for example, the lower side ) facing the bottom of the U-shape allows you to adjust the angle between the crossbar and the vertical bar to deviate from 90 degrees when necessary. Such a configuration allows the assembled fence to conform to any uneven surface on which it is installed.

The cross section of the crossbar 10 may be in the shape of a rectangle, where the diameter of the insertion hole 10A-1 in a first end face of the insertion hole 10A of the crossbar 10 can be less than the diameter of the hole of insert 10A-2 in a second end face facing the first end face (see FIG. 3). Such a configuration allows the assembled fence to conform to any uneven surface on which it is installed, since the size of the insert hole 10A-1 matches the size of the clip, the larger insert hole 10A-2 oriented towards the first insertion hole 10A-1 allows the adjustment with respect to the angle between the crossbar and the vertical bar to deviate from 90 degrees when necessary. When the crossbar is the highest or lowest crossbar, only one of the 10A-1 or 10A-2 insert holes is needed, and the other end face (opposite the end face with the insert hole) it may not have a hole.

The vertical bar may have a hole abutment side that includes a plurality of clamp holes 9-1 vertically aligned and spaced apart. For example, the vertical bar may have a number of (eg two) 9-1 clamping holes in a hole bearing surface corresponding to a number of (eg two) cross bars to be connected to the bar. vertical. In one example, the vertical bar is a hollow bar and has a first hole bearing side and a second hole bearing side towards the first hole bearing side. The plurality of clamping holes 9-1 may have the same or different configuration. For example, the uppermost portion of clamping hole 9-1 may have a tab 9-2 extending downward from its upper edge, while other clamping holes 9-1 do not have such a tab (see figure 4).

Hereinafter, a method of assembling a fence according to an embodiment not forming part of the present invention is described in more detail.

During assembly, the outer wall of the main body 3 '(eg, the section with the straight wall) is aligned with the insertion hole 10A of the crossbar and is inserted downward. The hole wall of the insertion hole 10A of the cross bar comes into contact with the inwardly inclined face 3-5 in the outer wall of the main body 3 '; and the inwardly inclined face 3-5 is pressed inwardly by the hole wall of the insertion hole 10A of the crossbar to satisfy the downward movement of the main body 3 '. When the main body 3 'moves down to the clamping groove 3-6 (that is, the clamping groove 3 6 comes into contact with the hole wall of the insertion hole 10A), the slanted face pressed 3-5 it is released through the hole wall of the insertion hole 10A of the crossbar, so that the inclined face 3-5 comes out (from the pressed state) and enters a hollow cavity in the middle of the crossbar; a side wall (for example, a single side wall) 10-1 of the crossbar 10 and the clamping slot 3-6 engages and locks (i.e., the side wall 10-1 is inserted into the clamping slot 3-6), at which point the side wall 10-1 of the crossbar 10 maintains an up and down locking relationship with the main body 3 'due to the function of the clamp groove 3-6, of so that the main body 3 'cannot move up or down, to keep the non-metallic clip (eg rubber) and cross bar fixed to each other. In this case, the thickness of the hole wall of the insert hole coincides with the separation distance of the clamping groove; the shape of the insertion hole matches that of the clip; and the outer diameter of the insert hole is slightly larger than that of the section with the straight wall, but less than that of the outwardly extending flange or that of the upper end face 3-3 of the section with the face tilted inward. Therefore, once the side wall of the crossbar engages the clamping slot and is sandwiched between the upper end face 3 3 of the inwardly inclined face 3-5 and the lower end face of the outwardly extending flange 3-1, the crossbar and the clip are locked together.

The vertical bar 9 (for example, a vertical bar 9 having an upper clamping hole 9-1 and a corresponding lower clamping hole 9-1) is inserted into the vertical bar insertion hole 3-2 of the main body 3 '; the hole bearing side of the vertical bar contacts an inner surface of the main body 3 'with the inwardly projecting shoulder 3-7, and the hole bearing side contacts the arcuate surface of the shoulder 3-7 on the inner wall of the main body 3 '; and the projection 3-7 of the main body 3 'is pressed (or pushed) to both sides (outward), so that the vertical bar 9 moves down smoothly.

When the vertical bar 9 is inserted down to a position so that the clamping hole 9-1 (for example, the lower clamping hole 9-1) of the vertical bar just coincides with the position of the projection 3-7 of the main body 3 ', projection 3-7 of main body 3' is released from the hole bearing side of the vertical bar (i.e. projection 3-7 is released from the pressed state since its position coincides with that of the clamping hole 9-1), so that the projection 3-7 exits (or moves inward) and enters the clamping hole 9-1 (for example, the lower clamping hole 9-1) of the vertical bar 9.

When the vertical rod 9 is further inserted downward, the hole bearing side of the vertical rod (for example, the upper edge of the lower clamping hole 9-1) comes into contact with the arcuate surface of the shoulder 3-7 at the inner wall of the main body 3 'and the projection 3-7 are pressed once more (for example, by the upper edge of the lower clamping hole 9-1) to exit the clamping hole 9-1 of the vertical bar 9 When the second vertical rod clamping hole 9-1 (for example, the upper clamping hole 9-1) just coincides with (reaches the position of) the shoulder 3-7 on the inner wall of the main body 3 ', the hole bearing side of the vertical bar is released from the pressed state, so that the projection 3-7 on the inner wall of the main body 3 'comes out and enters the second vertical bar holding hole 9-1 , at which time the tab 9-2 of the second vertical bar holding hole ical 9-1 maintains a downward locking relationship with groove 3-9 in the middle of shoulder 3-7 on the inner wall of main body 3 ', so that the vertical bar cannot be continuously inserted downward; and a hole 9-3 (eg, a bottom edge) of the second vertical rod holding hole 9-1 maintains an upward locking relationship with the bottom end face 3-8 of the shoulder 3-7 on the inner wall. of the main body 3 ', so that the vertical bar cannot be pulled upwards, thus maintaining a locking relationship between the main body 3' and the vertical bar 9. In this case, the vertical bar can have a number of insertion holes corresponding to the number of crossbars with which they are to be connected. Only one of the insert holes needs to have the tab, such as the uppermost part of the insert hole. However, the arrangement of the insert holes and the tabs is not limited thereto. For example, the lowest insertion hole may have the tab.

The assembled fence can have various combinations of crossbar and vertical bar numbers. For example, the assembled fence may have a crossbar at the upper end of the fence and a crossbar at the lower end of the fence; two crossbars at the top end of the fence and one crossbar cross at the lower end of the fence; a crossbar at the upper end of the fence and two crossbars at the lower end of the fence; or two crossbars at the top end of the fence and two crossbars at the bottom end of the fence. The uppermost and / or lowermost portion of the crossbar may have two insert hole abutment sides facing each other with vertically aligned insert holes to allow the vertical rods to pass through and extend beyond the crossbar. most superior and / or inferior; or the uppermost and / or the lowermost crossbar may have only one insert hole bearing side and does not allow the vertical bars to pass through and extend beyond the uppermost and / or the lowermost crossbar.

According to embodiments that are not part of the current invention, in addition to connecting a cross bar with a vertical bar, the elastic non-metallic clip is also suitable for connecting the cross bar and the vertical bar of the fence gate to the door frame, as well as to connect the fence to the post, as shown in figures 6-13 respectively.

Figure 6 is a schematic diagram of the structure of a fence gate; Figure 7 is an enlarged partial view of part A of Figure 6; Figure 8 is a partial cross-sectional view of part A of Figure 7; Figure 9 is a schematic diagram of a fence structure including posts; Figure 10 is an enlarged partial view of part B of Figure 9; Figure 11 is a partial cross-sectional view of part B of Figure 10; Figure 12 is a partial enlarged view of part C of Figure 9; and Figure 13 is a partial cross-sectional view of part C of Figure 12.

As shown in Figures 6-8, the clip can be used to secure an assembled fence gate (including cross bar and vertical bar) to the door frame. In one example, the clip is fixed on the door jamb through the 3-6 clamping slot, and the crossbar of the fence door is fixed on the door jamb through the vertical bar insertion hole 3 -two. That is, the clip is used with its top surface positioned vertically with the clamp groove matching the thickness of the door jamb wall, and the insert hole matching the size of the crossbar. The rest of the cross bars and vertical bars of the fence gate are assembled as described above. In one example, the clips for attaching the crossbar to the door jamb are a different size from the clips for attaching the crossbar to the vertical bar. Herein, the door jamb has an insert hole abutment side facing the direction where the fence door crossbar comes from, and the rest of the door jamb sides have no holes.

As shown in Figures 9-13, a fence may include a plurality of posts arranged spaced apart from one another and with a plurality of cross bars and vertical bars therebetween. The clip can be used to attach the cross bars and vertical bars of the fence to the posts. In one example, the clip is attached to the post through the clamping slot 3-6, and the crossbar is attached to the post through the vertical bar insertion hole 3-2. That is, the clip is used with its top surface positioned vertically. The rest of the cross and vertical bars of the fence are assembled as described above. Similar to the door jamb, a fence post at one end of the fence may have only one insert hole supporting side. Also, when the post is in the middle of the assembled fence and is connected with two cross bars arranged on two opposite sides of the post along the horizontal direction (see Figures 12-13), the post may have a first hole insertion hole on a first side face and a second insertion hole on a second side face facing the first side face, a clip can be used to lock with each of the connection holes respectively, and used to connect the post with a cross bar respectively.

Figures 42A-B are schematic illustrations of a fence installed on a flat surface (A) and an inclined surface (B). As illustrated in Figure 42B, a second larger insert hole 42-2 on a lower side of the crossbar (compared to the first insert hole 42-1 which needs to match the slot in the clip) allows The vertical bar is fixed at an angle other than 90 ° to the cross bar, and therefore allows the fence to be installed on an inclined surface.

Although the clip has been described in association with the assembled fence, the application of the clip is not limited thereto. The clip can be used to assemble or hold together two parts perpendicular to each other. For example, the clip can be used to assemble or hold two hollow parts together, as in the assembly of a piece of furniture, a device, etc.

The shape of the clip can be rectangular, oval, hexagonal, triangular, or any suitable shape. Figures 14-20 show various views of a rectangular clip according to an embodiment that is not part of the present invention; Figures 21-27 show various views of a triangular clip according to an embodiment that is not part of the present invention; Figures 67-73 show various views of a triangular clip according to another embodiment that is not part of the present invention; Figures 28-34 show various views of an oval clip according to an embodiment that is not part of the present invention; and Figures 35-41 show various views of a hexagonal clip according to an embodiment that is not part of the present invention.

Although a trapezoid shape has been described as an example of the shape of the insert hole 44-2 of the cross bars, the shape of the insert hole 44-2 of the cross bars is not limited thereto. Furthermore, although a trapezoid shape has been described as an example of the overall shape of the clip in connection with an M-shaped vertical rod insertion hole, the shape of the clip and the shape of the vertical rod insertion hole are not limited. to the same. Furthermore, although an M-shaped vertical bar has been described, the shape of the vertical bar is not limited thereto. For example, the vertical bar can have any suitable shape for a vertical bar, the vertical bar insertion hole of the clip can have any suitable shape that matches the shape of the vertical bar, the overall shape of the clip can be any suitable shape. that accommodates the vertical bar insertion hole of the clip (for example, the overall shape of the clip can be the same or similar shape to that of the vertical bar insertion hole, or different), and the shape of the insertion hole of the Crossbars can be any suitable shape that matches the overall shape of the clip.

Figure 46A is a cross-sectional view along line D-D 'of Figure 45A and Figure 46B is a cross-sectional view along line E-E' of Figure 45A. The upper end face 46-7 of the section with the inwardly inclined face and the lower end face of the outwardly extending flange 46-6 forms a clamping groove, and this clamping groove is matched with the thickness of a single wall of the crossbar (so that a single wall of the crossbar can be inserted and locked with the clamping groove). The shoulder 46-3 extends from the top to the bottom in the shape of a convex arc and is configured to insert into the clamping hole 43 in the vertical bar (see Figure 43); and the lower end face 46-5 of the shoulder 46-3 is configured to abut against a hole in the clamping hole 43 in the vertical bar. Also, slot 46-4 matches tab 43-1 so that the vertical bar cannot be inserted downward.

Fig. 47 is a schematic diagram showing the connection of the vertical bar, the cross bar and the clip in an assembly according to an embodiment of the present invention; Fig. 59 is a schematic diagram showing the connection of the vertical bar, the cross bar and the clip in an assembly according to another embodiment of the present invention; Fig. 48 is a cross-sectional view showing the connection of the M-shaped vertical bar, the cross bar and the clip in an assembly according to an embodiment of the present invention, where it can be seen that the vertical bar connects with the clip through a clamping hole in the middle 48-1 of the M-shaped vertical bar; and Figures 49A-C are schematic diagrams showing the connection of the vertical bar, the cross bar and the clip in an assembly according to an embodiment of the present invention.

During assembly, the bottom side 45-1 of the clip aligns with the insertion hole 44-2 of the crossbar and it is inserted downwards. The hole wall of the insertion hole of the cross bar contacts the inwardly sloping face 46-7 on the outer wall of the main body; and the inwardly inclined face 46-7 is pressed inwardly by the orifice wall of the insertion hole 44-2 of the crossbar to satisfy the downward movement of the main body. When the main body moves down into the clamping groove (that is, the clamping groove comes into contact with the hole wall of the insert hole 44-2), the pressed inclined face 46-7 is released by the wall of hole of the insertion hole of the crossbar, such that the inclined face 46-7 comes out (from the pressed state) and enters into the interior of a hollow cavity in the middle of the crossbar; then a side wall (for example, a single side wall) of the crossbar and the clamping slot engage and lock (i.e. the side wall is inserted into the clamping slot), at which point the side wall of the crossbar maintains a locked up and down relationship with the main body due to the function of the clamping groove, so that the main body cannot move up or down, to keep the non-metallic clip (for example, rubber) and the crossbar attached to each other. In this case, the thickness of the hole wall of the insert hole coincides with the separation distance of the clamping groove; the shape of the insert hole matches that of the clip. Therefore, once the side wall of the crossbar engages in the clamping slot and is sandwiched between the upper end face of the inwardly inclined section 46-7 and the lower end face of the outwardly extending flange 46-6, the crossbar and the clip lock together.

Next, the vertical bar is inserted into the vertical bar insertion hole 45 of the main body; the vertical bar contacts with an inner surface of the clip with the shoulder 46-3 protruding inward, and the shoulder 46-3 is pressed (or pushed) outwardly, so that the vertical bar moves downwardly uniformly.

When the vertical bar is inserted down to a position so that the clamping hole 43 of the vertical bar just coincides with the position of the shoulder 46-3 of the clip, the shoulder 46-3 of the clip is released by the vertical bar ( that is, the projection 46-3 is released from the pressed state since its position coincides with that of the clamping hole 43), so that the projection 46-3 comes out (or goes out towards the interior) and enters the interior of the clamping hole 43 of the vertical bar. When the vertical bar is further inserted downward, the vertical bar (for example, the upper edge of the lower clamping hole 43-2) comes into contact with the inclined surface of the shoulder 46-3 on the inner wall of the clip and the shoulder 46-3 is pressed again (for example, by the upper edge of the lower clamping hole 43-2) to move out of the clamping hole 43-2 of the vertical bar. When the second vertical bar clamping feature 43 (for example, the clamping hole 43) just coincides with (reaches the position of) the shoulder 46-3 on the inner wall of the clip, the shoulder 46-3 is released from the state pressed, so that the projection 46-3 on the inner wall of the clip pops out (out) and enters the inside of the second vertical bar clamping feature 46, at which point the tab 43-1 of the vertical bar coincides with the position of the slot 46-4 in the middle of the shoulder 46-3 and maintains a downward locking relationship with the slot 46-4, so that the vertical bar cannot be continuously inserted downward. A hole (eg, a bottom edge) of the vertical bar attachment holes 43 and 43-2 maintains an upward locking relationship with the lower end face 46-5 of the shoulder 46-3 on the inner wall of the clip. , so that the vertical bar cannot be pulled upwards, thereby maintaining a locked relationship between the clip and the vertical bar. Herein, the vertical bar may be a hollow bar with an interior space defined by an interior wall surrounded by an exterior wall. However, the vertical bar can be a solid bar without any interior opening.
