Description

[Detailed description of the invention] [Field of industrial application] This invention locks the free end of a lid that is attached to one side edge so that it can be opened and closed freely, thereby preventing the lid from opening and closing arbitrarily. This invention relates to a locking device for an opening/closing lid that releases the above-mentioned locking with a simple operation and can be opened freely when opened, and relates to a locking device that can be effectively implemented, for example, when locking the lid of a console box of an automobile. .

[Prior Art] Various proposals have been made for locking devices for hinged lids, and many practical examples are known. Among these many conventional locking devices for locking the lid of a console box of an automobile, a device as shown in FIG. 8 has been put into practical use as a general device.

The illustrated locking device has a window 101 near the opening edge of a console box 100, and a catcher 102 formed by bending a metal plate into a substantially U-shape is installed inside the window 101, and one side edge is hinged so that the window 101 can be opened and closed freely. A hook 104 with an arrow-shaped tip is attached to the attached lid 103. When the lid 103 is closed, the hook 104 is pushed between the two pieces of the catcher 102 through the window 101 and held by the elastic force of the hook 104. When the lid 103 is opened, the hook 104 is inserted into the free end of the lid. By hooking one's finger on the hook and pulling it up, the hook was pulled out from the catcher and released. Incidentally, something similar to this was made in 1986.
-Disclosed in Publication No. 84468.

This conventional device has a structure that relies on the elasticity of the metal material that forms the catch, and the structure itself is extremely simple and can therefore be provided at low cost. However, due to the difference in elasticity, the hook The locking force varies and is unstable, and this locking device cannot be opened unless the lid is pulled directly by hand. It was necessary to prepare a part on the lid for one's fingers to rest on, which resulted in defects such as spoiling the appearance.

[Problems to be solved by the invention] In view of the above-mentioned points, the present invention first aims at achieving a constant locking state when a lid such as a lid is closed, especially considering the stability when locking and the appearance. It was devised for the purpose of obtaining a high-quality product and being able to install it without damaging its appearance. The present invention also makes it possible to open the lid with a simple operation by pressing the button when releasing the lock, and when opening the lid, the hook covers the window to improve the appearance. Furthermore, when the hook is locked and the lid is closed, the hook and the main body of the locking device that locks the hook are in close contact to prevent rattling, and when installed in a car, etc. The purpose is to effectively prevent the generation of noise caused by rattling.

[Means for Solving the Problems] In order to achieve the above-mentioned purpose, the present invention improves the locking means for locking the hook and the operating means for releasing the locking state and opening the lid. It is characterized by a lock main body for hooking a hook provided on the lid, an operation button for operating the lock main body, and a case with one end of the lock main body open facing the hook; A slider is housed inside the case and is always biased in the opening direction by a compressed spring, and a slider is provided at the tip of the arm that is freely swingingly supported on a bearing provided in the case and is normally swinging. and a locking member that is forced into the opening from the side of the case by the bias of a spring that retracts the locking pawl, and the slider has the locking pawl of the locking member at the abutting portion that faces the opening of the case. A recessed portion is provided to avoid this, and the abutting portion is always located outside the hook locking position of the locking claw, and when the lid is closed, the slider is pushed into the case by the pressure of the hook and is engaged with the locking claw. To provide a locking device for an opening/closing lid, characterized in that a latch is held between the two, and when the lid is opened, the locking member is swung by pressing the operation button to release the engagement of the locking pawl. There is a particular thing.

[Function] The device of the present invention having the above configuration is implemented, for example, as a locking means for the lid of a console box of an automobile. In this case, a lock main body and an operation button are installed opposite to the lock main body on the console box side, and a hook is installed on the opening/closing end side of the lid, and when the lid is closed, the hook is pushed into the case opening of the lock main body and housed inside. Butt against the abutting part of the slider,
Push this into the case against the biasing spring. As a result of this pushing, the locking pawl of the locking member facing the opening of the case is temporarily retracted, and then is locked to the hook using the bias of the spring. While this restricts the opening of the lid, when the lid is opened, when the operating button is pressed and the locking member, which is the main body of the lock, is swung, the locking pawl that locks onto the hook is released, and the lid can be opened freely. Become. Simultaneously with this opening operation, the slider biased by the spring is pushed out, causing the hook to protrude and lift the lid from the opening of the box, so that the lid can be easily pulled up and opened by hooking a finger on the edge of the box. You will be able to do that.

In this manner, the device of the present invention engages the lock member by pushing the hook provided at the free end toward the lock body as the lid is closed, and the lid is restrained in the closed state. When opening, the locking member is disengaged by pressing the button, and at the same time it is raised to make it easier to place the finger on the locking member and to open the locking member.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments illustrating a locking device according to the present invention will be described, and its features will be explained in detail.

[Embodiment] The illustrated embodiment shows an example in which the present invention is implemented as a locking device for a lid 2 which is hinged to a console box 1 of an automobile so that it can be freely opened and closed. Figure 2 is a cross-sectional side view of the main part of the lock when the lock is opened, Figure 3 is a plan view of the lock main body, and Figure 4 is a partially cutaway side view of the lock main body. FIG. 5 is a front view, and FIG. 6 is a plan view of the center longitudinal section of the operation button.

The lock main body 3 includes a housing-shaped case 4 that opens upward, and a slider 6 that is housed inside the case and is biased toward the opening 4a of the case by a spring 5 that is constantly compressed. , a locking member 11 that is supported via a shaft 8 on a bearing 7 extending from the bottom of the case, and that a locking pawl 10 provided at the tip of a sliding arm 9 is pushed into the opening 4a from the side of the case; The operation button 12 is composed of a case 13 for mounting, and a button 12a that is housed in the case and has a pressing plate 15 that projects outward through a hole 14 formed at the bottom of the case.

To further explain the lock main body 3 above, case 4
is formed into a horizontally long housing shape, and a horizontally long slider 6 is housed in this case.

The slider 6 has a protrusion 17 that slides into a slit 16 vertically opened on the left and right sides of the case, so that it can freely slide up and down inside the case. 5 in the direction of the opening 4a, and the abutting portion 6a at the upper end is pressed against the opening 4.
When the protrusion 17 is protruded outside of the slit 16, the protrusion 17 is brought into contact with the upper end of the slit 16 to prevent further protrusion. (See Figure 5).

The case 4 is provided with a vertical notch 18 extending from the opening 4a at the center of one side wall, through which the locking pawl 10 of the locking member 11 is received. A recess 19 is provided corresponding to 18 to avoid engagement with the locking pawl 10.

The locking member 11 is provided with a pivoting piece 20 corresponding to the bearing part 7 extending from the bottom of the case 4, and is attached to the left and right sides by pivoting this piece through the shaft 8. The main body portion connecting the pivot pieces 20, 20 is provided with a sliding portion 21 that slides onto the press plate 15 of the operation button 12.

The lock member 11, which swings about the shaft 8, has an arm 9 extending from the sliding portion 21, and a locking claw 10 provided at the tip of the arm faces the opening 4a through the notch 18 of the case. Usually, the locking pawl 10 is held in the opening 4a by a spring 24 compressed between the protrusion 22 extending below the sliding portion 21 and the piece 23 extending from the bottom of the case. It is designed to enter and cross the opening 4a facing the recess 19 of the slider 6 (see FIG. 3).

On the other hand, the operation button 12 is provided with a recess 25 at the bottom of the horizontally elongated case 13 with a shallow bottom, and two elongated holes 14 are opened in parallel at the bottom of the recess. The plate 15 is made to protrude.

The button 12a in this embodiment is formed into a housing shape that fits in the case 13, and a locking piece 27 with a claw 26 at the tip extends from the center of the left and right edges, and this locking piece 27 is attached to the case 13. Locking hole 2 opened at the bottom of
8 and is assembled into the case to prevent the button 12a from coming off and to allow the button 12a to slide freely in the pressing direction using the pressing plate 15 as a guide. and,
Usually, a spring 29 is compressed between the case and the button 12a so that the button 12a stands out, and the pressing plate 15 protrudes from the hole 14.
is drawn into the case.

Now, the lock main body 3 and the operation button 12 configured as described above are formed separately and assembled, and one of the lock main bodies is attached to the back side of the opening edge of the console box 1 via the mounting piece 30 provided on the case 4. The opening 4a of the console box 4 faces the window 31 formed on the edge 1a of the box, and the operation button 12 is connected to the console box via a mounting piece 32 extending from the case 13 so as to be opposite to the lock main body 3. Attach it to the front position and expose the button 12a.

FIG. 1 shows the lid, which is hinged at one end, closed by the device of the present invention installed as described above. The lid 2 to be closed has a hook 3 formed by bending a metal rod on the lower surface of the free edge side.
3 is fixed with screws and hangs down, and closing is performed by hooking this hook 33 inserted through the window 31 to the locking pawl 10 of the locking member 3.

Upon this latching, as the hook 33 enters, the slider 6 protruding from the opening 4a of the case is pushed in against the spring 5, and then the locking pawl 10 that crosses this opening is moved onto its slanted upper surface. The tip of the hook 33 is slid to retreat outside the case 4 and then locked. Then, the hook 33 latched to the latching claw 10 is pressed by the slider 6 and is restrained in a pinched state.

In this state, when you next open the lid, press the button 12a of the operation button 12, and the locking claw 1
0 can be disengaged and released freely.

That is, when the button 12a is pressed, the pressing plate 15 presses the sliding portion 21 of the locking member 11 and swings the arm 9 about the shaft 8, so that the locking pawl retreats from the notch 18 and the hook 33 The engagement will be released. When the hook 33 is disengaged, there is no longer any force holding down the slider 6, so it protrudes from the opening 4a of the case 4 again under the bias of the spring 5.
Along with this, the hook 33 is pushed out and the lid 2 is lifted out of the opening of the console box.

The pressed button 12a is returned to its original state by the spring 29, and the locking member 11 is returned to the state in which the locking pawl 10 faces the opening 4a of the case due to the repulsion of the spring 24, and the next locking is performed. will be prepared for.

[Effects of the invention] The present invention is constructed as described above, and the hook provided on the lid can be locked by pressing the lid closed and restrained in the closed state. The cover receives repulsion from the slider pushed in when it hits this latch, and is latched while being held between the locking pawl, so even if there is a gap between the lids, etc. It is extremely convenient because it does not rattle and therefore does not make rattling noises even when subjected to vibrations from an automobile engine or vibrations associated with driving.

In addition, in the device of the present invention, when the locking claw is disengaged by pushing the button, the slider pushed in pushes the locked hook out, and the lid automatically lifts up.
The lid can be opened by placing a finger on the edge of the lid, so it is not necessary to provide a recess for the finger to be placed on the lid, as in conventional console box lids, or to form the lid edge so that it protrudes outward, spoiling the appearance. It is convenient because there is no such thing.

Of course, in the device of the present invention, the operation button is exposed, but it goes without saying that deteriorating the aesthetic appearance can be avoided by installing the button so that it does not protrude from the surface of the plate to which it is attached.

As mentioned above, in the conventional locking device, when the lid is opened, the opening into which the hook is inserted is exposed as it is, spoiling the appearance, but in the present invention, the window into which the hook is inserted is attached to the case. Since the slider protruding from the opening closes the opening, it does not remain open as in the conventional case, and good results can be obtained from this point as well.
