Abstract

PURPOSE:To automate latching by mounting to two respective objects a component comprising a stopper and a rail, and a component comprising a slit, a pin and a pin spring in such a manner that the claw of the slit passes through the center of the stand of the stopper. CONSTITUTION:An automatic latch comprises a component A1 which comprises a stopper 3 and a rail 4, and a component B2 which comprises a slit 5, a pin 6 and a pin spring 7. To mount the component A1 to a lid and the component B2 to a container main body, a claw B9 is allowed to pass through the center of a stand 10, and the pin 6 is given potential in the longitudinal and cross directions by the spring 7. When the lid is lowered the pin 6 abuts on a slope 11 and is then stopped by the claw B9, and when the lid is raised as it is pressed by the spring, the pin 6 is stopped by the claw A8; then the pin 6 is detached from the claw A8 by pushing down the lid, and when the lid is released the pin 6 is detached from the rail 4 so that the lid is raised. Latching is thus automated.

Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application This invention relates to an automatic latch in which the latch is automatically latched and unlatched.

B. Prior Art and Problems to be Solved by the Invention For example, conventional lids, doors, and drawers have been equipped with handles and push button switches for opening and closing. However, a beautiful product appearance was often obtained by designing the handle so that it was not conspicuous, and when the push button was small or there were many button switches lined up like in home appliances, Sometimes I ended up using my fingers instead of my chopsticks. If these handles and push buttons could be removed and the purpose could be achieved by simply pressing lightly on the lid, etc., the product would be easier to handle and the degree of freedom in product design would increase. Will.

In addition, with conventional storage shelves such as bookcases, in order to change the height of each tier, it is necessary to change the 4 clasps per shelf, which can be used when you don't want to place large items on a certain tier. However, it was not possible to adjust each step casually. If, 4
If there were a storage shelf where the clasps automatically engage and release, requiring no effort other than to raise and lower the shelves to the desired height, it would be useful not only for home interior storage shelves. It would also be useful for store display shelves and ponds.

What these devices have in common is that they require automatic latches that do not require any operation to unlatched, and can connect and disconnect two objects simply by manipulating the target object according to the purpose.

If such a thing existed, it would be possible to respond to it in various ways other than the lids and storage shelves mentioned above.

The object of the present invention is to provide an automatic latch that can be made small or large enough to withstand considerable pressure, and which automatically locks and unlatches.

0 Means for solving the problem of interlayers and the invention will be explained based on the drawings.

The invention consists of two parts, part A (1) (FIG. 1) and part B (2) (FIG. 2). The ones shown in Figures 1 and 2 are called standard types. Part A (1) consists of a stopper (3) and a rail (4), and part B (2) consists of a Z-shaped slit (5), a pin (6), and a pin spring (7).

The pin spring (7) applies force to the pin (6) in the direction of the arrow shown in FIG. In addition, each part of the stopper (3) shown in Fig.
This is called the slope α force, and the slit (5) shown in Figures 2 and 4
The - part is especially called claw B (9).

The thick lines in Figures 3 and 4 indicate the essential parts of both parts. The parts other than the grand prayer can be of any shape. The part indicated by the thick broken line above the slit in FIG. 4 is an essential part if the pin spring (7) is weak. If this part is missing and the top of the slit is open, it cannot be called a "slit", but it is most practical to make this part into a slit shape.
Including this case, all the pin (6) Z-shaped Y paths are called slits (5).

Figures 5, 6, and 7 are a perspective view (with the lid partially removed) and a side view of an illustrative embodiment of the invention in a container with a lid. The spring of the spring-loaded hinge is the body spring αa
1 The lid is called object A (13), the container body is called object B (14), object A (1: I is called object A (1), object B (1
Attach part B (2) to 4). For this installation, attach the center of the stand (10) to the tab B (as shown in Figure 10).
9) (so that claw B (9) passes over the vertical two-dot chain line in the center of Figure 10). However, in this case, the part B (2) may be attached to the object A C3, and the part A (1) may be attached to the object B (14). Both parts A C11,
B (2) The relativity of attachment is applicable throughout this invention. The main body spring C2 applies a force in the direction of opening the lid, or in the direction of separating the two parts in FIG. 10.

Figure 8 shows part A with the lid closed (Figure 7).
(1) (This is a sectional view seen from the side, especially showing the relationship among the stopper (31), part B (2), and pin (6).) Due to the force of the pin spring (7), the pin (6) moves into the 9M101iif
It has potential in the horizontal and vertical directions of f. These are called the horizontal potential and the vertical potential, respectively. The horizontal potential is smaller on the right side of the diagram, and the vertical potential is smaller on the bottom of the diagram. PI-P4 in Fig. 10 is the horizontal potential level, Pll.
PI2 indicates the vertical potential level. Further, the numbers ■-■ in the slit in the lower part of FIG. 10 are numbers indicating the position of the pin (6). When no force other than the pin spring (7) moves, the pin (8) will remain at the ■ or ■ position.

The operating method of this invention will be explained based on FIGS. 11-8.

Fig. 11 shows the relationship between component A (11), component B (21 (hereinafter illustrated by the shape of slit (5)), and pin (6) with the lid open. The upward arrow indicates the force of the main body spring (I3), the downward arrow indicates the force of the hand pushing the lid, and the horizontal arrow indicates the direction in which part A (1) moves. Part B (2) shows the force of the main body spring (I3). The pin (6) is in position ■.

When you push down the lid with your hand to close it, the pin (6) first hits the slope aυ of the stopper (3) (Fig. 11 2),
Next, by this slope αD and the force of the hand, P3 force λ et P4
Go up to ■ (Fig. 11, 3). When the lid is pushed all the way, the pin (6) comes off the slope (1υ), falls to the original ■ of P3 due to the lateral potential, and stops at the claw B (9) (first
1 Figure 4). When you release your hand, the lid rises due to the force of the main body spring (l
, and then P2 due to the lateral potential.
It falls to ■ and stops at claw A (8) (Fig. 11, 5). This is the closed state of the lid (see Figure 7 and #8).

To open this container, simply press down on the lid.

Then, the stopper (3) lowers, so the pin (6) comes off the claw A (8) and falls from P2 to Pl (■) due to the lateral potential (11th FyJ6). After releasing the hand, the lid rises due to the force of the body spring (Iz), and the pin (6) rises from Pl to P3 (■) due to the force of the rail (4) and body spring α2 (Fig. 11, 7). Pl2 due to the longitudinal potential off the rail (4)
It falls from Pll ■ and stops at claw B (9) (11th
Figure 8). This returns to the initial state S (11th ffl 1 ”), and this will be repeated thereafter.

This invention has almost no internal resistance when opening the lid (
5 and 6 in FIG. 11), and when closing, the oblique surface αfJh pin (G) is simply shifted to the side by its diameter (or radius) (FIG. 11, 2-3). Therefore, the invention operates with light pressure. Conversely, as shown in Figure 8, pin (6)
This invention is based on the same logic that it is difficult to bend a short piece of a nail because the force applied to the safety part AO) and part B (2) is small and the couple is small. It can withstand the heavy pressure of the pin (the action of the main body spring).And the method of controlling the pin (6) with the two-stage pawl AO) and pawl B (2) is the (One example of this is a storage shelf.)

Since the shape is as shown in Figures 1 and 2, this invention can be made both small and large. The material may be metal or plastic.

The shapes of Part A (1) and Part B (2) can be changed depending on the application, and in addition to the standard type (Figures 1 and 2), here we will broadly categorize vertical, horizontal, and flat types. List them one by one (first
Figure 2-25).

M type (in Figures 12-13, stand a1 and slit r5)
In the horizontal type (Fig. 18019), the rail (4)
The lower end of the slit (5) (at the location of the claw B (9)) is sloped to provide vertical potential. The flat pin (6) (FIGS. 20-23) uses a long rod that freely rotates around two axes α (FIG. 22). This may be done by making only the tip (the part that contacts component A (1) and slit (5)) thinner. In Fig. 21, the longitudinal potential is provided by the leaf spring αη, but in Fig. 23, the coil of the torsion coil spring αG, which provides the lateral potential, is shaped like an umbrella (with the pin (6) lowered in II). I am using a method of holding it down.

The pin (6) should be kept perpendicular to the component A (1) as much as possible. Of the pins for vertical and horizontal types, the 14th and 1st
Figure 5 is a perspective view of an example in which the pin spring (7) is hooked directly to the pin (6), and Figures 16 and 17 are parts B (2) using them.
) when viewed from the side.

Part A (1) a As shown in FIG. 24, the stopper (3) and the rail (4) may be plate-shaped (metal plates).

Alternatively, the path of the pin can be formed into a groove as shown in FIG. 25, but in this case, care must be taken not to unnecessarily restrict the movement of the pin, especially in the upper part.

The main body spring (13) and pin spring (7) are names that have the functions described above (pages 4 and 5), including gravity and human power.

(A theory of parts arranged in a band shape @) If the rail (4) of part A (1) is made into a waveform as shown in Figure 29 @, part B (2) will move from the top of the figure as shown in Figure 26. The pin (6) is held in the first position by the rail (4) both when going toward the stopper (3) and when going from below.
Fall to the position marked ■ in Figure 0, then move to Figure 11 4 or Figure 11 1.
The state will be as follows. As a result, part B (2) rises upward without stopping in Fig. 26, but moves downward towards the safety stopper (
3) will stop. If you lift it up a little when it stops, it will go down even further.

The pin (6) can also be square as shown in FIG. These parts A (band-shaped parts α1) can be used with the stopper (3) in a ring shape facing inward or outward, but they can also be used in a ring shape on a plane as shown in FIG. 28. Also, the items in Figure 29 may be arranged at intervals.All of these are called parts people.
Figure 6-29).

The same effect as described above can be obtained by arranging the parts B(2) in a strip instead of arranging the parts A(1) and using one part human wave αj shown in FIG. 29. It is also clear that both parts can be placed next to each other in order to reduce the load on the pin (6) or reduce the stopping distance.

In this way, an automatic latch is constructed in which one or both of the part A corrugated rail (4) of part A (1) is corrugated, and part B (2) are arranged in a band shape.

A U-shaped pillar can be made as shown in Fig. 34 by facing the symmetrical parts A wave α9 as shown in Figs. 30 and 33. This is called the dual belt■. FIG. 31 is a plan view thereof, and FIG. 62 is a front view thereof. For this dual belt {circle over (2)}, component B (2) with pins (6) attached on both sides as shown in FIG. 37 is used. FIG. 35 is a perspective view with the case partially removed, and FIG. 36 is a cross-sectional view taken along line A'.

Figure 40 shows the part A wave (
It is attached to the left and right sides of the l-yu, and this is the side plate pel)
C) Call it υ. No. 38ryJ is a perspective view of this as seen diagonally from above, and FIG. 39 is a plan view. In this side plate belt, as shown in Fig. 41, the pin (6) is made square, and the width of the base a is made to be about the same as the width of the pin (6). A configuration in which the width of (2) is narrowed can be used.

D Example (Example 1) Figures 42 to 47 show an example in which the present invention is applied to a waste bin. Figure 45 is a perspective view with the lid closed;
6Q is a perspective view with the lid opened 80 degrees, and FIG. 42 is a perspective view with a part of the lid removed. Part B (2)
Take a vertical type, attach a plate to the bottom, drill screw holes, attach it to the parts storage sack (2), and secure it from the outside with screws. Figure 44 is a perspective view of this and part A (11) with the lid slightly open.This is a waste bin, so in the unlikely event that trash interferes with the automatic latch and the lid does not open. In this case, when you turn the screw @ with a coin and pull it out, the part B (2) will be pulled out from the parts storage sack @ by the force of the body spring az.Remove the dust and remove the part B (2) again. All you have to do is put it on.This waste bin can be opened and closed by simply pressing the lid.

Although the following is unrelated to this invention, FIG. 43 shows a lid cam (2) which is inserted into a spring sack (2), which is covered with a tube (2), and which rotates around the rotation axis 124 of the lid. Fig. 3 is a cross-sectional view from the side of the attached lid with c). This will cause the lid to cam (ha)
Due to its shape, the brakes start to apply from the middle of opening;
zAtii relaxes, opens 90 degrees and stops. If you push it further open, it will open 180 degrees and stop. Even when throwing away waste,
As shown in FIG. 47, the opening state is maintained at 180 degrees or 90 degrees. The handle is convenient for carrying and does not take up space behind it.

(Example 2) Figures 48-49 show an example in which the present invention is implemented in a small box placed on a desk. Figure 48 is a perspective view with the lid open;
FIG. 49 is a perspective view with the lid closed. This invention, part A (1), part B (
2) can be implemented. Although the body spring is not shown, a bar spring that utilizes torsional elasticity may be used. This embodiment can also be opened and closed by simply pushing the lid with one hand.

(Embodiment 3) Figures 50 to 53 show an embodiment in which the present invention is applied to a set of two blackboards, and Figure 50 is a perspective view thereof. The two blackboards in the front and back move up and down alternately, and in the figure, the front board (to) goes up and the back board (3◇ goes down). Triangular rail like (!5
◇, and as shown in Figure 52, it is suspended by a wire (3→) that crosses the pulley (31), so that when one goes down, the other goes up. Figure 53 shows the left end of this example. This is a plan view of the section seen from above with the pulley C5 temple removed.A triangular wheel with a triangular recess (several three) is attached to the T-shaped support G5.This is a seven-triangular rail 0. By combining the front plate (3) and the rear plate (3 moves up and down, but is fixed front and back and left and right.It is attached to the back of part IA (11 is front plate Φ0), and part B ( 2) is located between the two plates and is attached to the three pillars (Figures 50 and 56).The front plate is slightly heavier (larger) than the rear plate (3).

With this configuration, as shown in Figure 50, when the lower end of the upper front plate (3) is slightly lifted, the front plate lowers and the rear plate (3ω rises, making it usable.) Conversely, it lowers and becomes usable. - When the front plate is lifted up (you may attach something that you can put your finger on the top of the front plate), the rear plate will drop and the front plate will be locked upwards and upwards by an automatic latch, making it ready for use. No matter how heavy the blackboard is, as long as the difference in weight is just slightly out of balance, the lifting force will be light.Also, create a gap between the two blackboards (Figures 51 and 53), and place thumbtacks or magnets on the blackboard. The blackboard can be raised and lowered without any problem even if it is stuck on the blackboard.Four sides of the blackboard can be used, and a larger blackboard can be used if it is attached to a classroom wall.

(Example 4) Figures 54 and 55 show an example in which this invention is applied to a storage case in a kitchen, etc. Figure 54 is a perspective view thereof, and Figure 55 shows parts A (1) and B (2). FIG. 3 is a cross-sectional view of the attached location viewed from the side. In the lower storage case, a spring with a spring-loaded hinge is used as the main body support A3, but in the upper storage case, gravity is used to force the door to open up to 90 degrees under its own weight, and a weak (soft) pin spring is used. I am using it. Both doors can be opened and closed simply by pushing the door, but only a light pressure is required for the upper compartment, and even short housewives can close it with their fingertips.

(Embodiment 5) Fig. 56 is a perspective view of an embodiment in which the present invention is applied to a drawer, with the nurse partially removed. This is also the main body spring a
Using gravity as z: When you push a closed drawer, the drawer will stay horizontal and will stick out toward you due to its own weight. The closed state is maintained by component A (11) and component B (2).In the figure, one component human wave α→ is attached so that the drawer stops once on the way before it is fully opened.

(Embodiment 6) Fig. 57058 shows an embodiment in which the present invention is implemented as a shelf for organizing files and drawings. FIG. 57 is a perspective view of one of the drawers opened, and FIG. 58 is a side view with the side plate partially removed. This is also an example in which gravity is used as the main body spring α and the drawer is made to have an extremely steep slope.

The closed state of the drawer is maintained by parts A (1) and B (2), and when the drawer is pushed, it opens fully and stops due to the number of parts, and when pushed a little further, the drawer comes out. The depth has been reduced, the overhead space has been revitalized, and documents on the top row can be searched at eye level for easy viewing.

(Embodiment 7) FIG. 59 is a perspective view of an embodiment of the present invention implemented in a letter case, with the case partially removed.

The main body spring is a leaf spring made by α3 company. In this way, part A (1
1. The main body spring (13) may start acting immediately before part B (2) is assembled, in other words, just before the drawer closes. When you push the closed drawer, it will release a little bit so that documents can be inserted. It can be opened and is similar to a regular drawer letter case. This also requires no handles on the front, and part A (fl) is made of plastic and can be integrally molded with the drawer.

(Embodiment 8) FIG. 60 is a perspective view of an embodiment in which the present invention is applied to a cassette door (of a cassette deck). This is also part A (
11 can be integrally molded with plastic. Part B is inside and cannot be seen. The entire lid is also a push button, so you can open and close the lid by pressing the lid itself, without having to operate another small push button.

It gets stuck and stops. If you press it from the right in this state, it will return to the state shown in Figure 64, and this will be repeated thereafter.

The structure can be made simpler by integrally molding several of these devices side by side.

(Embodiment 9) Figures 61 to 65 show an embodiment in which the present invention is implemented as a cassette extrusion device. This device is designed so that when a cassette that is not taken out is pushed in 3 mm, it will pop out 2 cm (Figure 71). The illustration of the pin (6) and pin spring (7) is omitted.

FIG. 61 is an exploded perspective view with a part of the case removed. This device consists of two parts incorporating part A (11) and part B (2), respectively. Figures 62 and 63 are front views of these two parts. Figure 64 shows the state in which the cassette is stored. FIG.

The broken man on the right shows the stored cassette (3'1). Pushing this from the right side of the figure releases the latch and releases the main body spring a3.
Press the cassette as in No. 65g:i (Example 1)
0) No. 66-71 [Jf: This is an embodiment in which this invention is also implemented as a cassette extrusion device, and is cheaper than the previous example. This device also consists of two parts, incorporating part A (1) and part B (2) (or Surin) (51), respectively. Figures 66 and 67 are perspective views of each part, and Figure 68 shows how the cassette is pushed out. FIG. 69 is a rear view of the state in which the cassette is stored, and FIG. 70 is a perspective view of the state. In this embodiment, one torsion coil spring (shown in phantom in Figures 67-69) is attached to a pin (67-69).
), pin spring (7), and main body spring α2. The vertical potential of the pin (6) (page 6, Figure 9010) is obtained by the spring coil, but the horizontal potential is obtained from the spring pin (6) in Figure 67.
This is obtained by making a torsion coil spring with the part opened to the right in the figure.

Note that the larger the diameter of the coil, the better, and it may be better to wind the fill in the opposite direction from the diagram.

FIG. 70 is a perspective view of IHfE type video cassettes lined up on a shelf, drawn to exact dimensions.

The height (inner diameter) of the shelf is equal to the appropriate diagonal length of the cassette, and it is the height that allows you to remove the cassette by pulling the top of the cassette upright on the left. Stack the cassettes in two tiers, line up all the cassettes in the back of the left end on the front of the cassette storage shelf, and install this device in the back.

If several pieces of this device are lined up and integrally molded, the structure will be much simpler and it can be produced at a lower cost.

(Example of arranging parts in a strip) (Example 11) Figures 72 and 73 show this invention when part B (2+ (flat type)) placed on a storage shelf (such as a bookshelf) is viewed diagonally from below. It is a perspective view. Part B (2) is attached to the four corners of the shelf board.

FIG. 73 is a perspective view of the left half of the storage shelf, and the right half is constructed in the same manner. The component human wave α field is drawn larger than the storage shelf itself for easy viewing. In order to "make the claw B (9) of the slit (5) pass through the center of the stand α1 of the stopper (3)", in the figure, a groove (3→) is provided in the center of the side plate, and a protrusion (3) is provided on the shelf. However, it is of course possible to use a method other than this.In the upper and lower ends of the side panels, cutouts 00 are made to insert the shelf board with 5 protrusions, but if the shelf board is placed diagonally, it can be stored. This is not necessarily necessary since it can be attached to the shelf body.

In this embodiment, the clasps that fasten the shelves are automatically engaged, and no effort is required other than to move the shelves up and down. To lower the shelf, all you have to do is lift it up a little, and it will go up without stopping (pages 1o and 11,
Figure 26). Even if there is a heavy item on the shelf, you can change the height by lifting one on each side.

This is an example carried out in the following. Fig. 72 is an example in which the present invention is implemented as a laundry drying rack (Example 12). Fig. 74 is an exploded perspective view, and Fig. 75 is a perspective view of the device in actual use. Stand two dual belts ■ on the ground and attach part Ef2) (third

I. Effects of the Invention As explained above, this invention allows two objects to be connected and separated by simply applying light pressure directly to the object to which it is attached. Furthermore, since it has a simple structure, it can be produced at low cost without requiring particularly sophisticated technology, and it can be made small or large enough to withstand considerable pressure.

As a result, the most easily conceivable use of this invention is to apply it to lids, etc., but even in that case, the labor of manipulating latches and handles for opening and closing can be saved, which is an effect that has almost never been seen in the past. occurs. Therefore, the product becomes easier to handle, and since there is no need for handles, the degree of freedom in product design increases, and users no longer have to worry about looking for small push buttons, which sometimes leads to space savings (see Figures 71 and 5 of the example).
Figure 0 and Figures 57-75 save space by utilizing the depth, bottom, and top spaces, respectively. In addition to being attached to conventional products, (the file/drawing organizing shelf shown in Fig. 57 of the embodiment, the cassette extrusion device shown in Fig. 71,
