Description

[Detailed description of the invention] [Field of the invention] This invention relates to a door opening/closing lock device used for kitchen furniture and the like.

[Conventional Devices and Disadvantages] Such a locking device has an engaging body and a lock body that can be fitted into each other at corresponding positions on the box body and door of kitchen furniture, and a heart-shaped contoured body is attached inside the body. A sliding body is provided with a groove and a protruding piece that can slide inside the groove, and by engaging the engaging body of the door with this sliding body, when the protruding piece is located in the trough of the heart-shaped groove. There is a known device in which the door is once locked and when the door is desired to be opened, the door is pressed again and a force that pulls the door in the opening direction acts to perform the opening operation.

This type of locking device has become widely used because the door can be easily opened and closed simply by pressing the door. However, kitchen appliances containing dishes, kitchen utensils, etc. that are equipped with such locking devices are usually mounted below or above the sink or stove. For this reason, since the door is opened and closed with one's back stretched or bent over, the force of pulling the door vertically is unavoidable, causing a so-called looseness that prevents the door from being placed in the correct position with furniture, etc., which allows insects to enter and is unhygienic. It is.

[Purpose of the present invention] This invention is a so-called one-touch opening/closing locking device that opens and closes the door simply by pressing the door, but it also allows the door to be locked while being corrected to the correct position. .

[Features of the present invention] The features of the opening/closing lock device of the present invention include a box-shaped lock body with an open front, a sliding body that can slide inside the body, and one end of each of the sliding bodies is pivotally attached to the body, and the other end is locked. a pair of claws located outwardly from the open surface of the main body and capable of protruding further outward from the main body; and a pair of claws provided on the sliding body to open the sliding body in the direction of the open surface of the main body and the other end of the claws in a figure-eight shape. a spring for applying a biasing force, a rail provided in the longitudinal direction on the outer surface of each of the pair of claws, and a pair of rollers provided in the lock body having an annular groove that can be fitted with the rail. and a groove having a heart-shaped profile cut in the sliding body and having at least two serrated steps and a depression provided between them, and one end of which slides in the groove in only one direction at all times. The other end has a protruding piece that is attached to an appropriate position on the main body and is applied with a biasing force in the groove direction, and a receiving seat that has an engaging body that is sandwiched between the pair of claws so that it can be held between the two claws. It is composed of the body.

However, for example, the seat body is attached to the storage box at an appropriate position on the door, and the lock body is attached to the storage box at a position corresponding to the seat body and at a position where both the pawls can engage with the engagement members of the seat body.

When you close the door that is currently open, first the tips of the eight-shaped claws on the back side of the door (the side where the seat body is attached) interpose the engaging body between the respective claws. When the door is further pressed in the direction of the storage box in this state, both claws grip the engaging body and move toward the main body.

At this time, both claws are guided and moved by the engagement of the annular grooves of the rollers provided on the main body and the rails provided on both claws, so even if the door has a so-called rattle, the mounting position of the lock main body and seat body cannot be adjusted. Even if there is a slight deviation in the door, the door will be moved while being semi-forcibly corrected to the correct position. As the door closes further, the sliding body slides within the main body in conjunction with the movement of both claws. As a result, the tip of the protruding piece in the heart-shaped groove is located from one side of the groove to the crest and into the depression, thereby preventing the sliding body and both pawls from sliding. In this state, when the door is locked in the storage box, when opening the door, press the door again, and the engagement between the recessed part of the heart-shaped groove and the engaging body will be released, and the sliding body, both claws, etc. will be moved from the sliding body. The main body is moved outward by the spring force of a spring piece provided in the main body, and the engagement between both claws and the engaging body of the receiver is automatically released, that is, the door is opened.

[Description of Embodiments] 1 is a box-shaped lock body made of a relatively hard synthetic resin material or metal casting, and the front side of the lock body is open. Reference numerals 3 and 3' designate a pair of upper and lower claws whose tips are located outward from the open surface of the lock body and whose rear portions can enter and exit the body 1 through the open portion.

The facing surfaces of the tips of both claws 3, 3' have concave notches 4,
4', the rear end of which is plugged into the upper and lower cuts 2, 2' of the front end surface of a sliding body 5, which is provided within the lock body 1 and is slidable along the axis of the body 1.

6 is provided on the sliding body 5, and the sliding body 5,
This is a spring piece for applying a biasing force to open the opening surface of the main body 1 and the tips of the claws 3, 3' in a figure-eight shape. 7, 7' are rollers provided in the front part of the main body 1 in the vertical direction, and have annular grooves 8, 8' in between. Further, rails 9, 9' that fit with the rollers 7, 7' are provided along the respective back surfaces of the claws 3, 3' over almost the entire length, and the rollers 7, 7' are fitted over the claws 3, 3'. When ' is moved inward of the main body 1, it presses the claws 3, 3' inward from the outside, thereby compressing the open ends thereof.

Reference numeral 10 denotes a groove having a heart-shaped outline provided in the sliding body, and is bored on the axis of the sliding body 5 in a sideways shape. 11 is a U-shaped projecting piece with a horizontal plane, one end of which fits into the rear of the groove 10 (see Fig. 1) when the door B is opened;
The other end is pivotally attached to the main body 1 at an appropriate position. Reference numeral 12 denotes a leaf spring that presses the protruding piece 11 from its back and acts so that the end of the pressing piece 11 inserted into the groove 10 is always in contact with the bottom of the groove 10.
1, but if the rear of the protruding piece 11 is pressed as much as possible as shown in the figure, the operation of the tip of the protruding piece 11, that is, the fitting end into the groove 10, will be smooth. Become.

In addition, as seen in FIG. 2, the heart-shaped contour groove 10 is at the rear end (on the opposite side from the pair of peaks).
A depression 1 formed between a pair of peaks passing through the upper side from
3, the depth becomes deeper, and the recess 1
A stepped portion is formed between 3 and the upper side, and the recess side is deeper, and the protruding piece 11 is located in this recess 13 to prevent it from moving toward the upper side when moving toward the rear of the groove 10. It is configured to do this. Further, no step is provided between the recessed portion 13 and the lower side of the groove, and the depth is gradually reduced toward the rear end of the groove. 10) has a deep step on the upper side.

The locking device body 14 having the above-mentioned configuration is provided with both claws 3 and
3' is attached so that it protrudes from the front.

15 is a seat body attached to the back side of a door B of kitchen furniture, for example, at a position facing the device body 14, and 16 is a seat body mounted on the back side of a door B of kitchen furniture, and 16 is a seat body mounted on the opposite recessed part 4 of the claws 3, 3'. 4' is an engaging body that can be engaged with the door B,
It is provided at the tip of a rod 17 provided on a catch seat 18 that is fixed to.

[Description of the operation of the embodiment] When the door B, which is currently open, is closed, the above-mentioned eight-shaped opening is first applied to the back side of the door B (the side to which the seat body 15 is attached). The tips of the claws 3 and 3' are located between the respective claws 3 and 3', and
The engaging bodies 16 are brought into contact with each other with the engaging bodies 16 interposed therebetween. In this state, when the door B is further pressed in the direction of the storage box A, the recessed portions 4, 4' of both the claws 3, 3' are removed by the seat body 15,
The engaging body 16 is inserted and held from above and below. At this time, both claws 3, 3' are guided by the engagement of annular grooves 8, 8' of rollers 7, 7' provided on the main body 1 and rails 4, 4 provided on both claws 3, 3'. Therefore, even if the door B has a so-called looseness or the lock body 1 and the seat body 15 are slightly misaligned in the mounting position, the door B can be semi-forcibly corrected to the correct position. You will have to move around.

As the action of closing door B further progresses, both claws 3,
The sliding body 5 slides inside the main body 1 in conjunction with the movement of the main body 3'. As a result, the tip of the protruding piece inside the heart-shaped groove 10 extends from the upper side of the groove 10 in the direction of the recess 13 formed between the peaks of the heart-shaped outline as seen in FIG. Since the groove 10 is formed to be deep, it moves and the recess 1
Located in 3. At this time, both claws 3, 3' are always supported by the spring pieces 6 of the sliding body 5.
Since a tensile force is acting in the direction in which the recess 13 is opened, the recess temporarily stops at the back wall of the recess 13. In this state, door B is locked to storage box A, and when the pressure on door B is released, door B remains locked.

Further, when opening the door B, when the door B is slightly pushed again, the claws 3, 3' and the sliding body 5 return to their old positions due to the restoring force of the spring piece 6, and the tip of the protruding piece 11 is inserted into the groove 1. , and returns to the old position through the lower side of the groove 10. In addition, at this time, the depression 1
3 and the groove 10 on the upper side, there is a stepped portion with a high upper side, so the protruding piece 11 does not move to the upper side.

As described above, the invention allows the door to open and close smoothly, and to ensure a secure locking action even when the furniture is loose.
