Abstract

The utility model relates to an installation kit for dining facilities, and is exclusively used for a base roller latch on a multifunctional revolvable table for hanging a turning plate. The utility model is characterized in that on the basis of an original roller latch on sale only a base needs to be connected to the original roller latch on sale and assembled on the multifunctional revolvable table. When a female table surface and the turning plate lie in horizontal states, one roller latch is rolled by another roller latch. The under turning plate can not automatically fall down. When the turning plate is wrenched, the rolled roller latch breaks loose from the rolling of the rolling roller latch.

Description

Base roller latch

The utility model relates to a kind of having dinner with the spare and accessory parts on the furniture, especially for the Base roller latch that tangles the table top turnover panel.

The applicant requires priority, application number: 93226189.2 on August 14th, 1993 to Patent Office of the People's Republic of China's application " multi-function turntable " utility model patent.

That sells on the market bumps pearl (or claim dog), and kind has several, but its function and purposes can only be used for the kitchen door, be to bump on the doorframe of kitchen on pearl and the kitchen door to bump pearl, when bumping pearl and box-up, kitchen edge (dress bumps this face of pearl) and kitchen door, these two planes are 90 ° of plumbness.If be used on " multi-function turntable ", two bump pearl when box-uping, female table top and these two planes of turnover panel are the horizontal parallel state, and don't make that following plane---turnover panel falls down voluntarily, influence is used, this class of selling on the market is bumped pearl and just can't be used at all, and this makes troubles often for the user of " multi-function turntable " in use.

The purpose of this utility model is will solve to be used for " multi-function turntable ", when turnover panel closes up, and when these two planes of female table top and turnover panel are in the horizontal parallel state, the problem that following turnover panel can not fall down automatically.A kind of improved Base roller latch can be box-uped turnover panel easily and turnover panel does not fall down voluntarily.

The purpose of this utility model is achieved in that it comprises and bumps pearl (A) and bump pearl (B).Bump pearl (B) with commercially available the same.Duck tongue (5), spring (9) being arranged, lay neutral gear (8) and the duck tongue slideway mouth (6) and the screw hole (7) of spring (9), can be two but bump pearl (B), also can be one.Bumping pearl (A) is by one or two slightly arc tongues (4), a tongue (4) connects an end of a riser (3), described tongue (4) is vertical configuration or skewed with this riser (3), the other end of riser (3) connects base (1) and forms, riser (3) is vertical configuration or skewed with base (1), and described tongue (4) is parallel substantially with base (1).As with two tongues (4), the slightly arc formed angle of another side of tongue (4) preferably becomes 70 °-140 °.Two tongues (4) can be equally high; Height also can be arranged, and then it just differs 0.7cm-10cm.Two risers (3) are connected to a shared riser (3) or are not connected, and riser (3) also can be done into strips, column.Base (1) is in homonymy, heteropleural or the both sides of tongue (4), is connected to a common-base (1) between two bases (1) or is not connected, and some screw holes (2) are arranged on the base (1).When bumping pearl (A) as two-way use, two tongues (4) respectively with this bump pearl (A) about bump each coupling of pearl (B); As when bumping the unidirectional use of pearl (A), only need a tongue (4), with bump the single only coupling of pearl (B).

The utility model is because single only bump pearl (B) with commercially available the same, when bumping the unidirectional use of pearl (A), only need connect a base (1) than commercially available, one poor just only, and function and purposes have difference in essence, so structure is simple especially, cost does not almost increase: simultaneously, because the starting point of invention does not lie in unidirectional and two-way use, so be easy to realize that the tongue (4) that bumps pearl (A) tangles the duck tongue (5) that bumps pearl (B), thereby when reaching these two planes of female table top and turnover panel and being in the horizontal parallel state, the requirement that following turnover panel does not fall down voluntarily.

Below with reference to accompanying drawing the utility model is described in detail.

Fig. 1 is the schematic diagram that tongue (4) that the utility model bumps pearl (A) tangles the duck tongue (5) that bumps pearl (B);

Fig. 2, Fig. 3, Fig. 4 are that the duck tongue (5) that the utility model bumps pearl (B) is shaken off the back schematic diagram;

Fig. 5 is that the utility model list only bumps pearl (A) schematic diagram;

Fig. 6 is that the utility model list only bumps pearl (B) schematic diagram;

Fig. 7 is that the utility model list only bumps pearl (B) reverse side figure.

Bump the tongue (4) of pearl (A), its effect is to contact by colliding with the duck tongue (5) that bumps pearl (B), box-upes or tangles the duck tongue (5) that bumps pearl (B).External force is done the time spent, collide with duck tongue (5) when tongue (4) and to contact, duck tongue (5) compresses spring (9), duck tongue (5) is shunk back from slideway mouth (6), at this moment, duck tongue (5) is by tongue (4), simultaneously, the spring (9) that has compressed is rapidly with duck tongue (5) spring-go original position, thereby plays the effect that the tongue (4) that bumps pearl (A) is box-uped or tangled the duck tongue (5) that bumps pearl (B).

Bump pearl (B) as not box-uping or tangling, under external force, duck tongue (5) same compression and elastic force effect owing to spring (9), in the contact of colliding of same tongue (4), duck tongue (5) is shaken off out.

Claims

1, a kind of Base roller latch of the turnover panel of box-uping comprises, the tongue (4) that bumps pearl (A) connects an end and the duck tongue (5), duck tongue slideway (6), spring (9) and the screw hole (7) that bump pearl (B) of riser (3), it is characterized in that, the other end of riser (3) also connects base (1), and some screw holes (2) are arranged on the base (1).

2, by the described Base roller latch of claim 1, it is unidirectional with bumping the single only coupling of pearl (B) to it is characterized in that bumping pearl (A), bump pearl (A) two-way with this bump pearl (A) about bump each coupling of pearl (B).

3, by the described Base roller latch of claim 2, it is characterized in that bumping pearl (A) has two slightly arc tongues (4) equally high, and height also can be arranged, and it just differs 0.7cm-10cm.
