Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a toggle latch assembly, and more particularly, the toggle arrangement is slidably reciprocatable between a first position and a second position, the assembly being in the first position. The solid body is held stationary by the toggle latch providing the entire assembly while the toggle latch is easily opened by moving the latch to a second position or g-co device. Toggle hooks relate to the entire assembly.

The entire toggle assembly includes a bracket device, a first and 11Jλ linkage device connected by a seventh movable pivot,
has. The first II linkage device is coupled to the bracket device by a second movable pivot, the second movable pivot being constrained to slide within a slot or aperture provided in the bracket device. The first linkage device is coupled to the bracket device via a third linkage device, and the IM3 linkage device is adapted to pivot about a fixed nine-axis axis attached to the bracket device. , the island λ and the third link mechanism device are connected by a ts3 movable pivot.

Such a hook allows the entire assembly to be moved between the first and first predetermined positions, and it
Therefore, when the second movable pivot is in the seventh predetermined position, the arrangement of the toggles is fixed, resulting in a nine device. The second movable axis is #l! - When slid into position, the power distribution of the toggle is arranged such that the toggle can be easily moved open.

It is an object of the present invention to provide an improved toggle catch. Other objects and advantages of the invention.

Description, drawings, and claims li! It will become clear from reading K thoroughly.

In FIG. 1, the entire toggle assembly 1 includes a bracket 3 having a plurality of mounting holes 5, the mounting holes 5 being brackets). ) and to secure the mother tongue when the toggle assembly l is in the closed position (see Figure 2), and to secure the mother tongue when the toggle assembly l is in the closed position (see Figure 2), and the toggle hook is in the closed position (see Figure 2). (See Figure 5) The entire toggle assembly 1 includes an opening mechanism 7 and a closing mechanism 9, which are pressed down to allow the toggle to be removed. The three-dimensional metal part 1t can be opened and closed respectively.

In FIG. 2, the toggle hook includes the entire assembly IFi, #E/linkage device 11, second linkage device 13 and third linkage device 15. The first link mechanism device 11 and the second link mechanism device 13 are connected by a seventh movable pivot 17.

The bracket 3 includes 19t of through holes and holes.

A second movable pivot 21 is slidably mounted within the through hole 19. gλ town motion axis 21 inside the through hole 19
9th, a roller 23 can be provided around the second axis 21 to facilitate sliding. As shown in FIG. 2, a biasing device, such as a spring 25,
is positioned between a part of the m2HI pivot shaft 21,
The iris lambda movable pivot 21 is biased toward a first predetermined position shown in FIG.

The II/Iiλ link mechanism device 13 has an irises 3 movable pivot 25
operably coupled to the third link rock formation device 15 by. Third link mechanism device 15Fi.

A bolt or the like 29, which is connected to the bracket 3 by a fixed pivot 27, is to be fixed and pressed against a tunnel (not shown).

29 can be attached to the three lick mechanism device 15.

Referring to FIG. 5, the effect of toggle latch assembly l is
1. #4 Do. When it is desired to open the entire assembly, the toggle hook is slidably mounted and the opening mechanism 7 is depressed so that the ninth λ movable pivot 21 assumes a second predetermined position, shown in dotted lines in FIG. . When the opening mechanism 7 is further moved beyond the position indicated by the dotted line in *2, the irises/linkage mechanism device 1
1 is now able to pivot around the second movable pivot 21, thus forcing the first OT# pivot 17 and the closing mechanism 9 upwards, and the third linkage device 15 and the third aT movable pivot 25
It can be rotated in the direction of the hour hand as shown in Figure t81.

The toggle can remove the force acting on the opening mechanism 7 and thus the second movable pivot 21 after the entire assembly 1 has been fully opened as shown in FIG.

It is then possible to float back to the first predetermined position shown in FIG. When the toggle hook is desired to close, the closing mechanism 9 is pushed down by an external force and thus #! / and second and third linkage devices 11.13. and 1
5 respectively until they are in the position shown in Figure 2.
The third link mechanism device pivots around the 39th axis 25, while the first link mechanism device 13 rotates Kk around the first movement axis 17, and the seventh link mechanism value 11 rotates around the 1ilL2 movable axis 21. Swirl around.

In FIG. 7, the arrangement of the entire assembly is as follows:
The toggle hook shown in FIGS. 1-j is similar to the overall assembly 1, but includes a second linkage mechanism 31 hidden between the first and second movable pivots 17 and 21. There is. No. 1 Hirolink Machine #
The function of the I-device 31 is to transfer the frictional force between the roller 23 of the second movable pivot 21 and the slot 19 to the bracket 3.

As shown in FIG. 2, the connection between the V-link rocking device 31 and the bracket 3 is depicted.

A biasing device, such as a torsion spring 33, can be utilized to force the first pivot 1lIl17Yr fixed and away from the ninth pivot 27. Furthermore, the gasket device 3
5 can be arranged around the opening mechanism 7 and the closing mechanism 9, respectively, to provide a secure closure.

1st town movement axis 17 The importance is that the 2nd eq @ axis 21 is the slot 19 in Fig. 2
It becomes clear when it is understood that the toggle is opened more easily when assuming the second predetermined position shown by the dotted line at the bottom of the NHC. The only force required to ensure that the toggle opens more easily is the force required to push down the bias value fil125. When this force is removed,
The toggle will return the entire assembly to the closed position shown in FIG.
The toggle hook is the position of the second town axis 21 with respect to the other axis of the whole assembly 1, and the toggle hook is the whole assembly d! Guaranteed to stay for a fixed t.

In light of the teachings of the present invention, toggle hooks can be modified and changed throughout the entire assembly! t can be done. It is therefore understood that, within the scope of the appended claims, the invention may be practiced otherwise than as described above.
