This application is based upon and claims priority to Polish Patent Application No. 440749, filed on Mar. 24, 2022, the entire contents of which are incorporated herein by reference.
The object of the present invention includes a bracket for mounting in a hole in a flat panel made out of a low density material, and in particular in an attic stairs hatch in order to mount it to a ladder or to mount other objects to it.
Attic stairs, where a hatch is suspended from the first segment of stairs using at least two pairs of connectors, which together with the first segment of the stairs and the hatch constitute a four-bar linkage system has been disclosed in patent PL228252B1. The connectors used to suspend the hatch are attached to it using hook brackets, and each has a bearing seat for an extension seated in the connector used to suspend the hatch. The assembly opening for this seat is covered by an insert which includes a bearing fill surface and is snap mounted in the hook connector body. The hook connector bearing seat has a pass-through opening on both sides, and the extension of the connector used to suspend the hatch terminates with a flange with a larger diameter than the diameter of the seat. This limits side movements of the extension in the hook connector by putting the extension flange or the connector used to suspend the hatch flush with one or the other side wall of the hook connector. In a closed state, the stop face of the insert covering the assembly opening to the hook connector seat, on the opposite side of the bearing fill surface, is flush with the support ridge in the body of the hook connector.
Known brackets are attached to flat panels using additional attachment means such as fastening screws, which however do not ensure adequate resistance of flat panels made out of a low density material. The present invention solves this problem through a bracket, mounted in a hole of a flat panel without additional attachment means.
The essence of the present invention includes a bracket for mounting in a hole in a flat panel. The bracket includes a base with a plate with at least one latching foot. The lower gap for the hole edge in the flat panel is located between the latching foot and the plate. The bracket base is fixed in the hole using the lock. In the first embodiment, the lock includes a locking foot which fills the hole in the flat panel which holds one of the base latching feet. Once the lock is inserted into the hole, the base becomes locked and the lock and the base are attached to one another by at least one coupling or adhesive. The bracket also includes a coaxial opening in the base and the lock which the pin used to suspend other elements is inserted into. Preferably the bracket is made out of plastic.
The bracket according to the present invention does not require additional attachment means in the form of screws in order to mount it on a flat panel, and its use ensures appropriate resistance of a flat panel made out of a low density material. This makes assembly quick and straightforward.
The illustration depicts the present invention, with given figures showing the following:
The present invention will be presented in an embodiment of a bracket mounted in a hole of a flat panel in the form of the surface of attic stairs closing hatch 1, to which ladder segment 2 is mounted. At least one hole 3 is made in closing hatch 1 for the bracket. The bracket is constructed out of base 4 and lock 5. The base includes plate 41 with two latching feet 42 with lower gap 43 for hole 3 edge 31 located between plate 41 and each latching foot 42. Bracket lock 5 fills hole 3 with bracket base 4 already inserted. Both base 4 and lock 5 include shaped faces, which ensure lock 5 is guided during assembly into the correct position in base 4. Lock 5 also includes couplings 51, 52, and base 4 includes coupling 44. During lock insertion into hole 3 they flex, and in base 4 locked position they are flush with appropriate base 4 and lock 5 surfaces fixing the bracket in hole 3. In the bracket assembled position, base 4 and lock 5 have a working section in the form of a coaxial hole 6 for pin 7. Closing hatch 1 is to be suspended on said pin 7. To that end, closing hatch 1 includes at least two brackets and attic stairs fittings include at least one flat bar 8 terminating with hook 81, inserted into gap 9 of the bracket, wherein pin 7 is perpendicular to the longitudinal direction of said gap 9.
