DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIGS. 1 and 2, a first preferred embodiment of a slide bracket of the present invention includes a main body (1), a locating holder (2), a hanging block (3), a retaining member (4), a spring (5), and a resilient member (6).
The main body (1) is provided with an end plate (11) and an opening (111) is provided on the end plate (11). One or a plurality of opening (111) may be disposed on the end plate (11) depending on the mounting of the main body (1). As illustrated, two openings (111) are provided on the main body (1). A pair of pivoting tags (12), each provided with an axial hole (121), is disposed on the main body (1) and a pin (13) is disposed to penetrate through the pair of pivoting tags (12). A limiting member (14) is disposed on the back of the end plate (11) and a retaining plate (15) is disposed near the pair of pivoting tags (12).
The locating holder (2) is connected to the front of the end plate (11) of the main body (1) and contains two chambers (21) corresponding to the number of the opening (111) as illustrated.
The hanging block (3) includes a first post (31) and a second post (32) connected to each other. The first post (31) is made in the form of square (or cylindrical, but not illustrated). The second post (32) is made in a cylindrical form. The first post (31) of the hanging block (3) penetrates through the opening (111) of the main body (1) into the chamber (21) of the locating holder (2) for the hanging block (3) to expand for movement. The spring (5) is inserted into the chamber (21) to function against the first post (31) of the hanging block (3) for it to provide a return force. A flange (311) is disposed on the first post (31) to hold against the opening (111) of the main body (1).
The retaining member (4) is pivotally connected to the pivoting tags (12) of the main body (1), and has a locking end (41) facing the back of the end plate (11) of the main body (1). The retaining member (4) is provided with the resilient member (6) which is a resilient plate having a clamping part (61) at one end to clamp on the retaining member (4) and a locating part (62) at the other end to hold against the retaining plate (15) disposed on the main body (1) to provide return elasticity to the retaining member (4).
The means for applying a return elasticity to the retaining member (4) is not limited to that as described above. As illustrated in FIG. 3, a resilient member (6a) is a torsion spring containing a force-applying end (61a) to hold against the retaining member (4) and a locating end (62a) to hold against the retaining plate (15) on the main body (1).
Now referring to FIG. 4, in order to mount the bracket to a support (9) provided with multiple of mounting holes (91), each made in a square form, the first post (31) of the hanging block (3) is inserted into the mounting hole (91) of the support (9) with the locking end (41) of the retaining member (4) holding against the support (9) while having the retaining member (4) and the end plate (11) of the main body (1) holding and securing the support (9). When adapted to a support (9′) provided with multiple round mounting holes (91′) as illustrated in FIGS. 5 and 6, the main body (1) has the second post (32) of the hanging block (3) inserted into the round mounting hole (91′) of the support (9′) with the first post (31) of the hanging block (3) to automatically retract in the chamber (21) of the locating holder (2) and to compress against the spring (5) disposed in the chamber (21).
In a second preferred embodiment of the present invention as illustrated in FIGS. 7 and 8, a first post (31a) and a second post (32a) of a hanging block (3a) are designed such that both posts to be inserted into each other. The first post (31a) is disposed with an axial hole (312a) for the first post (31a) to receive insertion of the second post (32a). Meanwhile, the second post (32a) has its inner end to be connected to a locating holder (2a). A restraining ring (33a) is disposed in the axial hole (312a) of the first post (31a) in order to be inserted onto the second post (32a). A chamber (21a) of the locating holder (2a) contains a first spring (51a) and a second spring (52a) with the former functioning on the first post (31a) and the latter functioning on the restraining ring (33a). The first post (31a) is provided with a flange (311a) to hold against the opening (111) of the main body (1). A gradation part (321a) is disposed on the second post (32) to relatively hold against the inner perimeter of the restraining ring (33a). Two tapered surfaces (313a, 331a) are respectively disposed on the axial hole (312a) and the restraining ring (33a), and the circumference of the restraining ring (33a) is provided with axial slots (332a).
As illustrated in FIG. 9, when adapted to the support (9) provided with multiple mounting holes (91), each made in a square form, the main body (1) has the first post (31a) of the hanging block (3a) inserted into the mounting hole (91) of the support (9) and the retaining member (4) holding against the support (9). To prevent the first post (31a) from being automatically retracted too easily so as to facilitate insertion into the mounting hole (91) of the support (9), when the first post (31a) is pushed against alone, as illustrated in FIG. 10, the tapered surface (313a) of the first post (31a) will compress the tapered surface (331a) of the restraining ring (33a). Because the second spring (52a) is holding against the restraining ring (33a), the restraining ring (33a) provided with the slots (332a) is forced to retract inward when pushed by the tapered surface (313a) of the first post (31a); and the retaining ring (33a) in turn holds against the gradation part (321a) of the second post (32a) to restrict the first post (31a).
When adapted to the support (9′) provided with multiple mounting holes (91′) with each made in a round form as illustrated in FIG. 11, the main body (1) has the front section of the second post (32a) of the hanging block (3a) inserted into the mounting hole (91′) of the support (9′). As the hanging block (3a) is pushed in further towards the support (9′) as illustrated in FIG. 12, the restraining ring (33a) is first pushed and retracted to allow its end provided with the axial slots (332a) to penetrate through the gradation part (321a) of the second post (32a) and further into the hanging block (3a). As illustrated in FIG. 13, the first post (31a) of the hanging block (3a) is also pushed to retract by the support (9′) to allow the second post (32a) to be pushed even further into the mounting hole (91′) of the support (9′) while the retaining member (4) is also holding against the support (9′).
In a third embodiment of the present invention as illustrated in FIGS. 14 and 15, a hanging block (3b) comprises a first post (31b) and a second post (32b). The second post (32b) is made in a cylindrical form. The first post (31b) is disposed with an axial hole (312b) for insertion of the second post (32b). The second post (32b) has its inner end to be connected to a locating holder (2b). A chamber (21b) of the locating holder (2b) contains a spring (51b) functioning on the first post (31b). The first post (31b) is provided with a flange (311b) to hold against an opening (111b) of an end plate (11b).
When adapted to the support (9b′) provided with multiple mounting holes (91b′) with each made in a round form as illustrated in FIG. 16, the second post (32b) of the hanging block (3b) is inserted into the mounting hole (91b′) of the support (9b′). As the hanging block (3b) is pushed in further towards the support (9b′), the first post (31b) of the hanging block (3b) is also pushed to retract by the support (9b′) to allow the second post (32b) to be pushed even further into the mounting hole (91b′) of the support (9′b) and the spring (51b) to be compressed.
A fourth embodiment of the present invention as shown in FIG. 17, comprises a locating holder (2c) and a hanging block (3c) which are in different directions compared to the above embodiments. The hanging block (3c) comprises a first post (31c) and a second post (32c). The second post (32c) is made in a cylindrical form. The first post (31c) is disposed with an axial hole (312c) for insertion of the second post (32c). The second post (32c) has its inner end to be connected to the locating holder (2c). A chamber (21c) of the locating holder (2c) contains a spring (51c) functioning on the first post (31c). The first post (31c) is provided with a flange (311c) to hold against an opening (111c) of an end plate (11c).
