Description

A positioning device for adding a pet guardrail to the fence (the second case)

The invention relates to a positioning device for adding a pet guardrail to a fence, especially the setting of the front cover plate on the front side of the upper cross bar and the lower cross bar of the pet guard rail, and the cover on the left and right ends of the upper cross bar and the lower cross bar. The cover can keep the side cover and the side post of the existing fence in close contact with the installation inclination angle of the existing fence.

By the way, in the courtyard of every household, in order to avoid the entry of idlers, fences will be erected around the courtyard. If the distance between the vertical poles or crossbars that make up the fence is too large, the pets raised to play in the courtyard will easily be caused by excessive size. The pitch rushes out of the road outside the courtyard, posing a collision hazard with passing cars. In order to prevent pets from rushing out of the fence, some people will add pet guardrails to the bottom of the existing fence to reduce the grid spacing of the existing fence. The pet guardrails that can be added, such as US patent numbers: 10,787,838, 6,832,752, 1,764,284, 1,445,307, 1,386,928, 1,312,242, 1,211,059, 888,905, etc., all have related structures for adding pet guardrails.

In the previous case of the present invention (referred to as the first case), the applicant of the first case applied for invention patents in Taiwan and the United States at the same time. Among them, the Taiwan invention patent application (Application No. 110146077) has been examined and approved and the license has been processed; the U.S. invention patent application (Application No. 17/558,822) is under review. In the first case, a positioning bolt is used to fix the connection between the upper rail, the lower rail and each straight rod of the pet guardrail. An upper and a lower two front cover plates are fixed on the outside of the locating bolt of the bar and the lower cross bar to cover the locating bolt. The arrangement of the upper and lower front cover boards increases the manufacturing cost unnecessarily. Furthermore, the side covers arranged on the left and right ends of the upper cross bar and the lower cross bar, the side covers of the first case are tied to the end of the side column facing the existing fence to form a vertical plane, and the vertical plane is inclined when the existing fence is installed. When the angle is too large and tilted at an angle, the right-angle position of the side cover will often collide with the side wall of the vertical side column, hindering the installation of the pet guardrail.

In view of the above-mentioned problems in the application of the first case, the present inventor makes a design improvement, and then has the generation of the present invention.
