Therefore, the storage operation of the drawer can be performed without being obstructed by the claw portion and the locking portion.

<< Embodiment >> An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIGS. 1 and 2 (a), (b) and (c) show a simple lock device for drawer to which the present invention is applied.

The simple lock device 1 shown in the figure is used for drawers such as a closet and a storage case, and includes a first member 2 and a second member 3.
It consists of two parts.

The first member 2 is made of a resin molded body, and has a mounting portion 4 and
A holding piece 6 that is obliquely raised with the thin hinge portion 5 as a base portion and an operating portion 7 for reducing the inclination of the holding piece 6 against the resin elasticity of the thin hinge portion 5 are provided.

The mounting portion 4 has a rectangular plate shape and has a connecting portion 8 which is vertically connected to the upper end face in the longitudinal direction. A triangular reinforcing rib 9 is provided between the side surface of the mounting portion 4 and the lower surface of the connecting portion 8 so that the connecting portion 8 has a supporting force.

A holding piece 6 is integrally provided at one longitudinal end of the connecting portion 8 with a thin hinge portion 5 interposed therebetween. The thin hinge portion 5 forms the base of the holding piece 6, and holds the holding piece 6 at a predetermined inclination angle.
And it is supported by a predetermined elastic supporting force.

The holding piece 6 has a substantially downward engaging portion 6a provided on the upper end portion of the holding piece, and the tilt of the holding piece 6 is reduced against the resin elasticity of the thin hinge portion 5 by pressing the operating portion 7. .

The operating portion 7 is provided so as to be substantially parallel to the mounting portion 4 and the connecting portion 8, and has its base side 7a joined to the lower end surfaces of the holding piece 6 and the locking portion 6a and extending from the base side 7a. Side 7b
Is set to the portion to be pressed.

Between the lower surface of the operating portion 7 and the other end portion of the connecting portion 8 in the longitudinal direction, a thin elastic piece 10 having one end portion connected thereto is interposed.

The thin elastic piece 10 is formed by forming a plurality of small reinforcing ribs 10a extending in the width direction on one surface of the thin piece so as to project along the longitudinal direction, and as a whole, a spring function is obtained.

The second member 3 is made of a resin molded body in which the mounting portion 11 and the claw portion 12 are integrally formed.

The mounting portion 11 has a rectangular plate shape like the mounting portion 4.
The claw portion 12 is projectingly provided on the one end portion side of the mounting portion 11 at a substantially right angle, and the inner side surface is set to engage with the locking portion 6a.

Next, the specific mounting and operation of the above simple lock device 1 will be described with reference to FIG.

FIG. 3 shows that the respective members 2 and 3 of the simple locking device 1 must be attached in correspondence with the storage portion B and the drawer C provided in the main body A such as a closet and a storage case, so that the gauge table D is used to accurately determine the position. In addition, this is an example in which positioning can be performed easily. A double-sided adhesive tape E is provided in advance on the mounting portions 4 and 11 of the respective members 2 and 3.

In the same figure (a), the second member 3 is placed in the storage portion B, the first member 2 is placed in the drawer C according to the gauge table D, and the double-sided adhesive tape E
It shows a completed state attached through.

Here, the gauge table D is made of paper of a predetermined size, and each member
The cutouts, which are set to attach 2 and 3 in a predetermined positional relationship, are divided by lines. The cutout portion is the attachment portion 4 of the first member 2, and the cutout portion is the attachment portion 11 of the second member 3.
Are sized so that they can be fitted together.

Further, the line d ₁ that divides the cutout portion is extended by the line d ₂ .

First, the thickness t of the front plate c ₁ in the drawer C is measured. Then, the cage Table D as shown in FIG. (B), draws a line d ₄ parallel to the line d ₃ at a distance corresponding to the thickness t.

After the cut-out portion is cut off, the second member 3 is fitted into the opening of the cut-out portion with its mounting portion 11 facing upward.

In this state, as shown in FIG. 3C, the drawer C is pulled out from the storage section B, and the cage table D is placed on the inner surface of the top plate b ₁ of the storage section B.
With the front edge of the top plate b ₁ and the line d ₄ of the cage table D aligned, and then press. As a result, the second member 3 is attached and fixed to a predetermined position on the inner surface of the top plate b ₁ via the double-sided adhesive tape E of the mounting portion 11.

Next, after removing the cage table D and cutting off the cut-out portion, the cage table D is positioned at the inner surface corner of the right side plate c ₂ of the drawer C as shown in FIG. The first member 2 is attached and fixed to a predetermined position on the right side plate c ₂ via the double-sided adhesive tape E.

In this way, the first member 2 and the second member 3 can be mounted accurately and easily by anyone by previously obtaining the mutual positional relationship in the mounted state on one cage table D.

When the drawer C is slightly pulled out from the storage portion B, the locking portion 6a is engaged with the claw portion 12 to restrict the drawer C from being pulled out.

Further, in this state, since the drawer C is slightly pulled out from the storage portion B, a hand or the like is inserted into the drawer C to prevent the operation portion 7 from resisting the resin elasticity of the thin hinge portion 5 and the thin elastic piece 10. By pressing downwards, the holding piece 6 moves in a direction in which the inclination is reduced with the thin hinge portion 5 as a fulcrum. Therefore, since the locking portion 6a is also moved downward together with the holding piece 6, the engagement of the locking portion 6a with the claw portion 12 is released, and the drawer C can be further pulled out.

On the other hand, it is difficult for an infant to pull out the drawer C while pressing the operation portion 7 as described above.
It is possible to sufficiently prevent the careless drawing out of.

On the contrary, in the process of sliding the drawer C into the storage portion B and storing it, the holding piece 6 hits the claw portion 12 from the thin hinge portion 5 side thereof and resists the resin elasticity of the thin hinge portion 5 and the thin elastic piece 10. Since the holding piece 6 is pushed, the inclination of the holding piece 6 is automatically reduced, and the holding piece 6 gets over the claw portion 12. Therefore, the storage operation of the drawer C can be smoothly performed without being hindered by the claw portion 12 and the locking portion 6a. Further, when the holding piece 6 has passed over the claw portion 12, it is returned and supported at the original predetermined inclination angle by the resin elasticity or the restoring force of the thin hinge portion 5 and the thin elastic piece 10.

The present invention is not limited to the above-mentioned embodiments, but can be variously modified within the scope of the invention.

For example, the first member may be attached to the storage section B side and the second member may be attached to the drawer C side. In this case, the specific structure of the first member has to be changed a little as illustrated in FIG.

The first member 20 in the figure is made of a resin molded body, and has a mounting portion 24, a holding piece 26 that is diagonally raised with the thin hinge portion 25 as a base, and holds the thin hinge portion 25 against resin elasticity. An operation unit 27 for reducing the inclination of the piece 26 is provided.

The mounting portion 24 has a rectangular plate shape, and has a connecting portion 28 that is joined at a right angle to one end face in the longitudinal direction.

A holding piece 26 is integrally provided on one end side of the connecting portion 28 via a thin hinge portion 25. The thin hinge part 25 is a holding piece
The holding piece 26 is supported at a predetermined inclination angle and with a predetermined elastic supporting force.

The holding piece 26 has a locking portion 26a facing downward at the upper end of the holding piece 26.
By the pressing operation of the operation portion 27, the inclination can be reduced against the resin elasticity of the thin hinge portion 25.

The operation portion 27 is formed so as to project from the back surface of the holding piece 26 to the front side of the thin hinge portion 25.

Therefore, when pulling out the drawer C a little,
12 and the engaging portion 6a are engaged with each other, so that the drawer C is prevented from being pulled out. In this state, the drawer C is slightly pulled out from the storage portion B. Therefore, a hand or the like is inserted into the drawer C to press the operation portion 27 against the resin elasticity of the thin hinge portion 25 or the like to hold the holding piece 26. If the inclination of is reduced, the engagement between the claw portion 12 and the locking portion 6a is released, and the drawer C can be further pulled out. Further, in the process of sliding the drawer C into the storage portion B and storing it, the claw portion 12 hits the holding piece 26 and is pressed against the resin elasticity of the thin hinge portion 25 and the like, so that the inclination of the holding piece 26 is reduced. The claw portion 12 gets over the holding piece 26. Therefore, even with this configuration, the same operation as that of the above-described embodiment can be obtained, and the same effect can be obtained.

<Effects of the Invention> As described above, in the simple locking device of the present invention, when the drawer is pulled out a little, the engaging portion engages with the claw portion and the drawer is prevented from being pulled out. It will not be pulled out carelessly by infants, etc., and it will be possible to prevent injuries or accidents caused by careless pulling out of the drawer.

Further, the present invention is characterized in that it is composed of two parts, a first member and a second member, and that the first member is made of a resin molded body and is suitable for mass production.
It can be offered at a bottom cost and can easily be fitted into existing drawers.

Moreover, the simple locking device of the present invention has a different original purpose from the conventional locking device composed of a lock and a hook, but for example, the first member and the second member are mounted in a place that is relatively hard to see. Therefore, it can be used as an alternative to the conventional locking device.
