The present invention is related to a positioning device for fence supplemented with pet guardrail, and more particularly to a device enabled to omit the front cover plate installed at the front side of the upper crossbar and lower crossbar of the pet guardrail and the side cover individually installed to cover the right and left sides of the upper crossbar and lower crossbar, thereby matching the setting inclination angle of the existing fence and maintaining fit and connect between the side cover and the side pole of the existing fence.

Description of the Related Art

In order to prevent people from entering for no good reason, fences are set up around the garden of a house. If the gap between the horizontal or vertical rods of the fences are too large, the pets will easily run out of the garden to the road and further cause the risk of collision while the vehicles pass. Therefore, in order to prevent the pets from running out of the garden, some people will supplement pet guardrails on the bottom sides of the existing fences so that to reduce the gap distance of the existing fences. The supplementary pet guardrails have been disclosed in the following U.S. Pat. Nos. 10,787,838, 6,832,752, 1,764,284, 1,445,307, 1,386,928, 1,312,242, 1,211,059 and 888,905.

Regarding the earlier application (first application) of the present invention, the applicant has corresponding applications file with USPTO and TIPO, wherein the Taiwan Patent application (Application No. 110146077) has been allowed and granted a Patent and the U.S. Patent application (application Ser. No. 17/558,822) is still under examination. In the first application, the each connecting point of the upper crossbar, lower crossbar and each straight rod of the pet guardrail is fixed by a positioning peg, and to avoid poor appearance or potential hurt to the pets due to the exposure of the plurality of positioning pegs, an upper front cover plate and a lower front cover plate are respectively fixed on the outside of the positioning peg of the upper crossbar and the lower crossbar to cover the positioning pegs. The configuration of the upper and lower front cover plates increases the production cost. Moreover, the side covers are installed on the left and right ends of the upper crossbar and lower crossbar, and in the first application, the side cover facing the side pole end of the existing fence is a vertical surface. When the installing inclination angle of the vertical surface on the existing fence is too large, the vertical position of the side cover will usually collide with the side wall of the vertically disposed side pole and obstruct the installation of the pet guardrail.

In view of the above problem of the first patent in actual applications, the inventor of the present invention made improvements to the design and developed the present invention.
