MOUNT LATCH STRUCTURE FOR A TELESCOPING SLIDE

The present invention relates to a mount latch structure for a telescoping slide, and more particularly to one allows fast mounting in position of a drawer or similar article.

In addition to using screws or similar locking members to respectively fasten two inner rails of left and right slides to both sides of a wooden drawer or the like, or pins are provided to he incorporated with insertion hole and inserbon plate of the telescoping slides in case of metal drawer or the like for mounting telescoping slides to the drawer or the like, there are more convenient means available from the prior art commonly observed in the cabinet products for computer servers and disclosed in US Patent Nos. 4,331,369, 5,632,542, 6,123,314, 6,209,979 BI, 6,588,866 B2, and 6,601,933 Bi, as well as US Patent Application Nos. US 2001/0040203 Al, US 2003/0141791 Al, US 2004/0108797 Al, US 2005/0088069 Al, and Taiwan Patent Publication No. 538716 i.e., US 2004/0108797 Al.

All those prior arts cited above share common problems of running higher production cost of the mounting member, less convenience in assembling, and lower benefits as a general; furthermore, the user could easily get cut by burrs since most members are made of metal materials.

The primary purpose of the present invention is to provide a mount latch structure for a telescoping slide to solve those so problems found with the prior art. To achieve the purpose, the slide includes an inner rail and an outer rail. The inner rail provided to receive the mounting by a drawer or the like Comprises at least two mounting holes and a mounting member adjacent to one mounting hole. Wherein, the mounting hole includes a vertical channel and a horizontal channel connected to each other. The mounting member is a resilient strap block with a first end locked to an irmer side of the inner rai] and a second end facing the horizontal channel of the mounting hole. A hollowed channel is formed between the first and second ends of so the mounting member to make both longer sides of the hollowed channel to each become a strap arm that allows resilient deformation and to further give the mounting member a pre-stress to he held in position. The drawer has on its sides provided with bolts corresponding in position to the mounting is holes. The bolt has a head in a diameter larger than that of the bolt. When the bolt enters into the mounting hole and further into the vertical channel, the head forces to push against the second end of the mounting member for both resilient strap arms to develop transient deformation and allow the head of the bolt sliding into the horizontal channel of the mounting hole. Both sftap arms return to their original shape and the mounting member is secured in place by having its second end holding against the head of the bolt.

Accordingly, when compared to the prior art, the present invention provides the following advantages: 1. Lower production cost since the mounting member may he made of plastic material.

2. Resilient strap arms and plastic material design for the mounting member prevent the user from being easily cut during operation.

A mount latch structure for a telescoping slide of the present invention is used in the installation of a drawer or the like. As illustrated in Figure 1, a drawer (4) allows to he fully pulled out by means of slides. The slide includes an inner rail (1), a middle rail (2) and an outer rail (3); or alternatively, the slide is composed of an inner rail and an outer rail to allow the drawer to he partially pulled out. However, either the three-or two-section configuration of the slide is a general practice and thus is not illustrated herein; furthermore, the present invention is not essentially characterized in the configuration of the slide. The present invention is characterized in the inner rail (1) to receive installation of the drawer (4).

The inner rail (1) is provided with at least two mounting holes (11.) and a mounting member (5). The mounting member (5) is adjacent to one of the mounting holes (11). Referring to Figure 2, the mounting hole (11) includes a vertical channel (111) and a horizontal channel (112) connected to each other.

The mounting member (5) is a resilient strap block and has a first end (51) locked to an inner side of the inner rail (1) and a io second end (52) facing the horizontal channel (112) of the mounting hole (11). A hollowed channel (53) is provided between the first and the second ends (51, 52) to define on each of both longer sides of the hollowed channel (53) a strap arm (54) that allows resilient deformation. The mounting member (5) is 5 pre-stressed to secure in place. In the preferred embodiment of the pre-stressed mounting member (5), the first end (51) of the mounting member (5) is disposed with a central hole (55) and at least a positioning post (56) corresponding to a riveting hole (12) and a positioning hole (13) disposed on the inner rail (1). A pin (6) penetrates and secures the mounting member (5) through the central hole (55) and the riveting hole (12). When the mounting member (5) is not pre-stressed, it is biased in relation to the horizontal channel (112) of the mounting hole (11) as illustrated in Figure 3. A protruding hit (57) and a limiting hole (14) are disposed on the back of the second end (52) of the mounting member (5) and the inner side of the inner rail (1). When the protruding hit (57) is coupled to the limiting hole (14) as illustrated in Figure 4, the second end (52) of the biased mounting member (5) is corrected so to become corresponding to the horizontal channel (112) of the mounting hole (ii) and pre-stressed to increase the strength of the mounting member (5) to he held in place. A slope (521) is provided on top of the second end (52) of the mounting member (5).

Bolts (41) are provided on both sides of the drawer (4) corresponding in position to the mounting holes (11). Each bolt (41) comprises a head (411) having a diameter larger than that of the bolt (41).

Accordingly, the bolt (41) of the drawer (4) hangs up downward the vertical channel (ill) of the mounting hole (11) as illustrated in Figures 5 and 6, the head (411) of the bolt (41) is located on the inner side of the inner rail (1) to force pressing the slope (521) on the second end (52) of the mounting member (5) for the resilient strap arms (54) to undergo transient deformation, and naturally slides into the horizontal channel (112) of the mounting hole (11). Once the bolt (41) slides into the horizontal channel (112), the strap arms (54) return to their original shapes as illustrated in Figure 7 with the front edge of the second end (52) holding against the head (411) of the bolt (41) to be secured in place, thus to secure the incorporated status between the inner rail (1) and the drawer (4).

Now referring to Figure 8, on considering that when the mounting member (5) has the first end (51) to he fixed to the inner

-

side of the inner rail (1), the second end (52) of the mounting member (5) may be warped in the horizontal direction given with weak rebounding strength of the resilient strap arms (54) when subject to improper external force or pull by mistake resulting in improper deformation of the mounting member (5).

Consequently, the second end (52) of the mounting member (5) can he easily pushed and warped by the head (411) of the bolt (41.) to compromise the failure of the mounting member (5). To solve this potential problem, a central hole (55A) and a o positioning post (56A) are disposed at a first end (51A) of a mounting member (5A) to correspond to a riveting hole (1.2A) and a positioning hole (13A) disposed on an inner rail (1A) as illustrated in Figures 9 and 10. A pin (6A) penetrates through the central hole (55A) and the riveting hole (12A). A hooking member (58A) is provided on the back of a second end (52A) of the mounting member (5A). A concave surface (1 5A) adjacent to a limiting hole (14A) is formed on the inner side of the rail (IA).

The hooking member (58A) penetrates through the limiting hole (14A) hooks against the concave surface (15A) so to restrict the second end (52A) of the mounting member (5A) from being warped in its horizontal direction.

As illustrated in Figure 11 for another preferred embodiment of the present invention, a retainer (1.6B) is provided on an inner rail (IB) to hold against an upper edge of a second s end (52B) of a mounting member (5B) so to correct the biased second end (52B) of the mounting member (SB) for it to correspond to a horizontal channel (112B) of a mounting hole (11B) and to become pre-stressed. Furthermore, as illustrated in Figure 12, a limiting plate (17B) extends downward from the top of the retainer (16B). The limiting plate (17B) holds against the top of the second end (52B) of the mounting member (5B) to restrict the second end (52B) of the mounting member (5B) from being warped in its horizontal direction.
