Description

[Detailed explanation of the idea] This proposal relates to a door holder/closing device for furniture, etc.

When it comes to furniture, etc., when the door is closed, the door should not open accidentally, and on the other hand, when the user opens the door, it should not require too much force. A closing device that maintains the door closed with a moderate retention force is often required. There are many types of closure devices of this type, and they can be broadly classified into:
There are some that rely on mechanical male and female snap engagement, and others that rely on magnetic adsorption force, but all of them are a combination of a pair of male and female parts (for magnetic ones, one is a magnetic plate and the other is a magnet). It must be attached to the door and the main body by screws or the like, and at least one part is still made up of a combination of several elements. Therefore, the assembly process and number of parts are large, the installation work is troublesome, and the cost is high.

On the other hand, if the weight of the door is large, especially for steel furniture, the side edge opposite to the side edge fixed to the main body by the hinge may sag, meaning the door itself may tilt diagonally. There is. Therefore, conventionally, this type of heavy door needs to be provided with a door holder on the main body side that presses the lower edge of the door to prevent it from falling down when the door is closed.

In the end, the above-mentioned closing device has to be installed together with the door holder, which increases the frequency of work and increases the cost.In addition, the appearance of the product is also difficult because it is made up of separate parts. There's no way it's going to be good if it's just stuck in a random spot.

In view of the above, this proposal aims to provide a rational device in which the door holder and the closing device are integrated into one component and can be fastened to the main body side by a simple operation. In conjunction with this, the minimum processing required on the door and main body is either a simple recess, a blind hole, or a through hole.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

1 to 3 show a door receiver/closing device 1 according to the first embodiment, and the device 1 is constructed by integrally molding each of the components described below by plastic injection molding into a single component. ing.

In this example, the application to steel furniture is illustrated, and the door 2 includes a front iron plate 2a, a rear iron plate 2b, an iron plate (not shown) connecting the upper edges and side edges of both iron plates, and a lower edge. It is shaped like a box frame and consists of a bottom plate 2c that connects the space. Although not shown in its entirety, the bottom 3 of the main body is also hollow and thick, with the upper and lower plate parts 3a and 3b connected by the front part 3c, and there is an elastic packing 4 on the front of the front part 3c. is attached to improve the sealing of the room when the door 2 is closed, and also to prevent the door and the main body from directly colliding with each other and causing damage or making noise when closing. There is. However, it will be clear from the following explanation that the furniture does not have to have this configuration, and may be a very ordinary piece of furniture that simply consists of a single-piece bottom plate and a single-piece door.

The door receiver/closing device 1 is connected to the furniture bottom plate 3 (in this case,
More specifically, it has a substrate part 5 that comes into contact with the bottom surface of the lower plate part 3b from the back, and in FIG. Consider it as the substrate section 5.

A snap locking member 7 that snaps into a locking hole 6 provided in the bottom 3 of the furniture is provided on the upper surface of the base plate portion 5. In this case, the snap locking member 7 includes a U-shaped pillar 8 that stands upright from the surface of the base plate and is inserted into the locking hole 6 from the upper end, and slits 11 on three sides of the pillar on both sides, leaving the upper edge. an elastic piece 9 that is surrounded by an elastic piece 9 that is flexible inward and outward, and is provided so that its lower end is a free end;
9, and locking claws 10, 10 provided on the outside of this elastic piece so as to project outward.

The distance between the surface of the locking claws 10, 10 facing the base plate 5 and the base plate 5 is the hole edge thickness of the locking hole 6 of the furniture bottom 3, in this case, the plate thickness of the lower plate 3b of the bottom 3. It is equal to or slightly shorter than this. Further, the distance between the protruding ends of both the locking claws 10, 10 is larger than the width w of the locking hole 6, and the width w and length l of the locking hole are dimensioned to allow insertion of the pillar 8. ing.

From the front edge of the substrate portion 5 assumed by the virtual line L,
First, in this case, an elastic and flexible arm piece 12 is integrally molded with the base plate 5 and extends from the center position in the width direction, and a protrusion 13 that protrudes upward is provided at its free end.
is provided, and this protrusion 13 (in this case, kamaboko type)
As will be described later, it becomes an engaging member with the door to lightly hold the door 2 in place.

On the other hand, the arm piece 12 and the protrusion 1 that serve as this closing device
In this case, door receiving pieces 14, 14 extend from the front edge of the base plate 5 shown by the imaginary line L on both sides of 3, integrally but separately from the arm piece 12. In the embodiment, the front ends of the pair of door receiving pieces 14, 14 are connected to each other by a door introduction piece 15 so as to cross the front end of the arm piece 12, and this introduction piece 15 is configured to move downward due to the action described below. It is sloping.

Considering the above configuration, when viewing the device 1 as a whole, a U-shaped slit 16 is cut in the widthwise center of one plate-like member slightly forward in the front-rear direction, and the arm piece 12 is cut with this. It also looks like U-shaped flat parts 14, 15, and 14 are formed around it as it is raised up.

To attach the device 1 to the bottom 3, the pillar 8 of the snap locking member 7 is inserted from the tip into the locking hole 6 of the bottom 3 (lower plate 3b). Then, from the above dimensional relationship, the claws 1 provided on the elastic pieces 9, 9 on both side walls of the column 8.
When the upper surfaces of 0 and 10 come into contact with both edges of the locking hole 6 in the width direction and the entire device 1 is further pressed toward the bottom, the elastic pieces 9 and 9 are pushed inward through the locking claws 10 and 10. It is bent and passes through the locking hole 6 in that state. Eventually, when the locking claws 10, 10 cross the corresponding hole edges, they are restored by the repulsive force of the elastic pieces 9, 9, which had been deflected until then, and the lever claws 10, 10 and the surface of the substrate portion 5 are connected to the bottom. (lower plate) to lock it in place (Figure 3). In this state, the protrusion 13 of the arm piece 12 connected to the base plate and the tip of the door support piece 14 extend beyond the front surface of the bottom 3 (in this case, since there is a gasket 4, the front surface becomes the front surface of the bottom). It is growing, and we will design it so that it will continue to grow.

On the other hand, the bottom 2c of the door 2 that opens and closes with respect to the main body has a recess or engagement recess that accommodates the protrusion 13 at a position corresponding to the protrusion 13 on the free end of the arm piece 12 when closed. 17 is set. In this embodiment, a steel door is assumed, so in such a case, the recess 17 can be created by pressing the bottom plate 2c of the door at the time of making the door. Of course, this recess need not be blind with an arcuate top plate 17' as in the illustrated case, but may be a through hole open upward.

To explain the function of this door holder/closing device 1,
When the open door 2 is closed toward the main body as shown in the first figure, the front edge 2c' of the bottom of the door is exposed to the protrusion 13.
It corresponds to the leading edge of If you continue to push the door toward the main body, the door bottom edge 2c' will bend the arm piece 12 downward via this protrusion 13, but when the door 2 is just aligned with the main body, the protrusion 13 will also bend into the recess in the door bottom plate. Consistent with 17,
The arm piece 12 restores itself by its own elasticity and fits the protrusion 13 into the depression with a click feeling.

As a result, the closed state shown in the third figure is achieved, the door 2 can be easily maintained in the closed state, and the closing function as one of the functions of the present device is satisfied.

Of course, when opening the door as necessary, initially,
When the protrusion 13 relatively comes out of the recess 17, there is a slight resistance, but it can be opened through the same flexible action of the arm piece 12 as described above.

Another function of this device is to support the door 2 from below in the closed state, as is clear from FIG. 3, by the door support pieces 14 holding down the bottom of the door. In addition, in order to enhance this function, door holder piece 1
4 and 14 are not flexible and are preferably strong, so in order to achieve this, the door holder and the base plate should be made sufficiently thick, or the door holder should be inserted from below the door holder as shown in the figure. Preferably, the reinforcing ribs 18, 18 are erected in series down to the bottom of the board.

On the other hand, the arm piece 12 having the closing engagement protrusion 13 may be required to be highly flexible and pliable, but in that case, the lower surface of this arm piece may be thinned out. Alternatively, the connecting portion with the substrate portion 5 as a hinge may be made thinner.

Conversely, according to the present invention, the door support piece 14, which is required to be sturdy and withstand the weight of the door,
14 and the closing arm piece 12, which requires appropriate flexibility in terms of operation feel, can be integrally molded on the same substrate part 5, and it is rational that both functions can be obtained with only a single installation operation. be.

Also used in this example. The door introduction piece 15, which is oriented diagonally downward, allows the bottom of the door to ride on this introduction piece 15 during the movement from the open state to the closed state, even if the opened door is heavy and tilted. This is to ensure that it reaches above the door support piece that maintains the horizontal state. However, it may not be necessary in some cases.

It is desirable that the device 1 is prevented from rotating relative to the bottom 3 of the furniture. For this purpose, in this embodiment, an insertion hole (locking hole) is provided in the snap locking means 7.
The cross section of the pillar 8 inserted into the base plate 5 is made into a non-circular rectangular shape, and the locking hole is also made into a rectangular shape, and the geometric combination of both prevents rotation. A protrusion may be provided, and a recess or hole for receiving the protrusion may be provided on the bottom surface of the corresponding bottom 3.

Further, the snap locking means 7 itself may have a known snap locking structure of this type, for example, an anchor type or canoe type fastener structure, or may be implanted from the base plate 5 as in the second embodiment shown in FIG. It may also be of a hook type with an outwardly directed locking pawl 10 attached to a standing leg 8'. For example, if a pair of these hook-shaped ones are installed back to back as shown in the fourth figure, the locking hole 6 on the corresponding bottom plate may be a large hole in which both are inserted on one side, or a pair in which each one is inserted individually. A hole in the hole may be used.

Furthermore, as illustrated in FIG. 4, the door receiving piece 14 is
Not only can the size and area be arbitrary in terms of design, but also the number of pieces may be one piece provided only on one side of the arm piece 12. Other changes in shape are optional as this proposal is aimed at resin molded products, and changes in shape to suit the product (furniture),
Furthermore, it may be of a different color tone. Of course, protrusion 13
may have an arbitrary shape, for example, a hemispherical shape.

In any case, according to this proposal, the door holder function and the door closing function can be obtained with a single part that can be locked and attached to the bottom plate of the main body with a simple snap action, and the processing required for the door and the main body can also be achieved. Since it can be minimized, it is extremely advantageous and rational in terms of work, cost, and design.
