Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to a door stop (hereinafter simply referred to as a door stop) of a door with a locking function, and more particularly to a door stop capable of locking the door to an inner wall surface of a room by pushing or pulling the door.
[0002]
[Prior art]
For example, as shown in FIG. 1, the door-to-door 1 is a stick-like body, such as a kokeshi doll, which is implanted on the floor near the inner wall 2 of the room and has a spherical head, for example. This prevents the free end from colliding with the inner wall 2 and has a buffering function.
[0003]
A normal door stop has a locking function to keep the door open. For example, as shown in FIG. 1, it is supported so that it can rotate around the horizontal axis at the lower edge of the free edge of the door. The door 3 is locked by hooking the U-shaped hooks to the door-to-door 1.
[0004]
[Problems to be solved by the invention]
Since the conventional door with a locking function having the above-described structure is planted on the floor surface, it may not only be easy to spread and dangerous depending on the installation location, but also becomes an obstacle when cleaning the floor surface.
[0005]
In addition, when laying a carpet or the like on the floor surface, it is necessary to cut or make a hole in that portion in order to avoid interference with the door stop 1.
[0006]
Furthermore, when the U-shaped ridge 4 or the like is hooked on the door-to-door 1 or removed, it is difficult for the elderly or the physically handicapped person to squat down.
[0007]
In addition, when the door 3 is closed without knowing that the door 3 is locked to the door-to-door 1, there are various inconveniences such as the occurrence of noise due to a collision at each part.
[0008]
Therefore, the present invention proposes a new door stopper with a locking function that is rationally designed, and aims to eliminate the various disadvantages described above.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, the present invention is suspended from any one of the vicinity of the free side edge on the upper side of the door inner surface and the portion of the inner wall adjacent to the vicinity of the free side edge of the door upper side when the door is opened, It has a catcher that is a flat box-like body with an open end, and a plate-like hook that is suspended on the other of the inner surface of the door and the inner wall so that the front end can be inserted into the inside of the catcher when the door is opened. The center of the opening end of the catcher is provided with a pinion having a substantially rectangular projection shape on the bottom surface and formed with substantially V-shaped notches on both short sides thereof, and the center is pivotably supported on the bottom surface. Also, on the opposite side of the pinion to the opening of the catcher, a control plate that is guided so as to be movable in the length direction in the catcher and is urged toward the opening is provided, so that no external force acts on the control plate. In this control The front end edge of the hook is brought into contact with and locked to the pinion, while the front end of the hook is formed in a bifurcated shape so as not to interfere with the pinion when inserted into the catcher to form a pair of operating arms, Cut the outer edge of the front end of each arm diagonally, and widen the front end of one working arm inward so that the inner edge rubs without interfering with the long side of the pinion through a slight gap. In addition, a locking corner portion is formed on the hook base end side of the inner end edge, and a control protrusion that interferes with the pinion is formed between the base end portions of the pair of operating arms. It is characterized by that.
[0010]
【Example】
Embodiments of the present invention will be described below with reference to the drawings.
2 to 4, reference numeral 5 denotes the entire catcher. The catcher 5 is a flat box-like body in which, for example, the main body 6 and the lid plate 7 are coupled to each other by screws (not shown).
[0011]
The main body 6 has a shape in which the upper surface and one side surface (the left side surface in FIGS. 2 and 3) of the flat box-shaped body are open, while the lid plate 7 has an elongated rectangular shape that covers the upper surface of the main body 6. It is a plate-like body.
[0012]
And these main-body part 6 and the cover board 7 utilize the four screw holes 8 and 8 (refer FIG. 2) formed in the four screw holes and the main-body part which were opened in the cover board 7, and abbreviate | omitting illustration. Thus, a flat box-like catcher 5 having one end opened as shown in FIG.
[0013]
In addition, in order to make it easy to insert a hook, which will be described later, into the catcher 5, a chamfered portion 9 may be formed at the opening end portions of the main body portion 6 and the cover plate 7.
[0014]
Further, in the back of the bottom surface 11 of the main body 6 and the lid plate 7 (to the right in FIGS. 2 to 3), spring grooves 11 a each having a cross-sectional shape forming a part of an arc (see FIG. 4) are formed. .
[0015]
Incidentally, in FIG. 3, the upper surface of the main body 6 is generally referred to as the bottom surface, and the inner surface (lower surface) of the lid plate 7 is generally referred to as the ceiling surface. However, the catcher 5 is not necessarily attached to a door or the like in the manner shown in FIG. In this case, both the bottom surface and the ceiling surface are referred to as the bottom surface.
[0016]
On the other hand, as shown in FIGS. 5 and 6, a pinion in which the projected shape with respect to the bottom surface 11 is substantially rectangular at the center of the opening end inside the catcher 5 and substantially V-shaped notches 13 are formed on both short sides thereof. 12 is provided.
[0017]
As shown in FIG. 5, the pinion 12 is pivotally supported so as to be rotatable around a support shaft 14 that is vertically installed on the bottom surface 11 of the catcher.
[0018]
On the other hand, on the opposite side of the pinion 12 to the opening of the catcher, that is, on the right side of the pinion 12 in FIG. .
[0019]
The control plate 15 is guided so as to be movable in the length direction of the catcher 5, that is, in the left-right direction in FIG. 5, and one end is wound around a spring hanging piece 15 a formed integrally therewith, and the other end The control plate 15 is urged in the opening direction of the catcher (leftward in FIG. 5) by the elasticity of the urging spring 16 (see FIG. 5) as a compression coil spring that is in contact with the back of the catcher 5.
[0020]
Needless to say, the urging spring 16 is housed in a space between the spring grooves 11a and 11a in the catcher 5.
[0021]
For the sake of clarity, the biasing spring 16 is not shown in the drawings subsequent to FIG. 6, and only the biasing direction is indicated by an arrow.
[0022]
As described above, the control plate 15 is urged to the left in FIG. 6, but in a normal state, in other words, in the standby state in which the hook described below is not inserted into the opening of the catcher, the notch 13 , 13 are held by the pinion 12 at an angular position that makes the front-rear direction (the left-right direction in FIG. 6) the position shown in the figure.
[0023]
On the other hand, the hook 17 inserted into the opening of the catcher 5 when the door is opened is configured, for example, as shown in FIG. That is, the hook 17 is a plate-like body having a substantially rectangular outer shape, and its front end portion (right end portion in FIG. 7) is formed in a forked shape so as not to interfere with the pinion 12 when inserted into the catcher 5. A pair of operating arms 18, 18 are formed.
[0024]
Further, the outer end edge of the front end portion of each operating arm 18 is cut off obliquely and is easily inserted into the opening of the catcher 5.
[0025]
Furthermore, the long side of the pinion 12 in which the front end portion of one operating arm 18, that is, the upper operating arm 18 in the seventh illustrated embodiment is widened inward, and the inner end edge thereof is at the angular position shown in FIG. The width dimension of the front end portion of the operating arm is set so that it can be rubbed through a slight gap without interference.
[0026]
As described above, as a result of the front end portion of the upper working arm 18 being widened inwardly, a step portion is formed at the center portion of the upper working arm. 19 is an important component of the present invention.
[0027]
In addition, a control projection 21 that interferes with the pinion 12 is formed between the base end portions of the pair of operating arms 18 and 18.
[0028]
The control projection 21 in the illustrated embodiment is formed at the approximate center of the base end portion of the pair of operating arms 18 and 18 and engages with the notch 13 at the rear of the pinion at the angular position shown in FIGS. The tip of the control plate 15 is substantially parallel to the front edge of the control plate 15 so that it can be slightly rotated counterclockwise.
[0029]
The door contact with a locking function configured as described above according to one embodiment of the present invention uses a pair of screw holes 22, 22 opened in the cover plate 7 of the catcher shown in FIG. Combined with other intermediate mounting members, it hangs on either the free side edge near the upper side of the door inner surface or the inner wall part near the free edge near the upper side of the door when the door is opened. Set up.
[0030]
The hook 17 is also rotatably coupled to a bracket (not shown) via a connecting pin (not shown) passing through a pin hole 23 opened at the base end, and the tip of the hook 17 is connected to the catcher when the door is opened via this bracket. It is hung on the other of the inner surface of the door and the inner wall so that it can be inserted into the inside from the opening.
[0031]
As shown in FIG. 7, there are two screw holes 22 but only one pin hole 23 of the hook 17 is open. Since the free end of the door moves circularly, either the catcher 5 or the hook 17 is used. This is because if the swinging is not performed, the hooks 17 are twisted when inserted.
[0032]
As described above and as shown in FIG. 6, since the hook 17 is not inserted into the catcher 5 when the door is closed, the pinion 12 is at an angular position as shown in FIG. 6 and abuts against the front edge of the control plate 15. The rotation is stopped.
[0033]
Near the end of opening the door, the front end of the hook 17 is inserted into the catcher. With the configuration described above, the operating arms 18 and 18 are inserted to the back without interfering with the pinion 12, and the front end of the hook is connected to the control plate 15. Matches the front edge of the abutment.
[0034]
When the door is further opened, there is a little resistance due to the elastic force exerted by the biasing spring 16, but the hook is further inserted into the catcher while the biasing spring 16 is retracted, and as shown in FIG. The projection 21 is engaged with the notch 13 of the pinion.
[0035]
Then, the pinion 12 rotates in a counterclockwise direction, in other words, a little so that a part of the pinion 12 enters the movement locus of the locking corner of one of the operating arms, and the pinion 12 is connected to the support shaft 14 via the pinion 12. I am stopped.
[0036]
When the force to open the door is weakened at this time, or when the hand is released from the door, the biasing spring 16 is pushed through the control plate 15 and the hook 17 is pushed out so that the hook 17 is pushed out. In FIG. 8, the control protrusion 21 moves to the left to free the pinion 12.
[0037]
Therefore, as shown in FIG. 9, the hook engaging corner 19 is engaged with the notch 13 of the pinion, and the hook 17 is fastened to the catcher via the pinion 12, so that the door is engaged with the hook 17 and the catcher 5. It is latched by the inner wall via.
[0038]
In FIG. 9, one of a pair of non-numbered protrusions (left protrusions in FIG. 9) with the engaging corner 19 sandwiching the V-shaped notch 13 of the pinion is pushed to the left, and the pinion 12 Is counterclockwise, the other projecting piece bites into the inner edge of the operating arm 18 above the hook, so that the hook 17 cannot move to the left.
[0039]
When it is necessary to close the door, the door is once further pushed toward the inner wall. Then, as shown in FIG. 10, the hook 17 pushes the control plate 15 inward of the catcher 5 against the urging force.
[0040]
Then, the engagement between the locking corner 19 and the pinion 12 is released, the pinion 12 becomes free, and the control protrusion 21 of the hook 17 now pushes the central part of the long side of the pinion 12.
[0041]
Then, the pinion 12 is slightly rotated counterclockwise, and the other protruding piece of the pinion 12 enters the movement locus of the locking corner 19.
[0042]
In this state, when the door is turned in the closing direction, the hook corner 19 pushes the end of the long side of the pinion 12, so that the pinion 12 is further counterclockwise as shown in FIG. Finally, the hook 17 is removed from the catcher 15 through the engagement state shown in FIGS. 12 and 7.
[0043]
Then, since the door integral with the hook 17 becomes free from the catcher, the door can be closed by further rotating the door in the closing direction.
[0044]
【The invention's effect】
As is apparent from the above description, in the present invention, the hook is pushed twice after the catcher is inserted as one cycle, the pinion is slightly rotated by the first push, and the notch is formed at the hook corner of the hook. Is moved into the movement trajectory, and the locking corner that is pushed back by the control plate is engaged with the pinion, the hook is locked to the catcher, and the hook is released from the pinion by the second pressing of the hook. In addition, the pinion is rotated a little further, and the pinion is placed at an angular position that does not interfere with the hook through the locking corner by the second retraction of the hook, so it is automatically opened simply by opening the door fully. There is an expected effect that the door can be locked to the inner wall and the door can be closed only by pushing the door in the opening direction again.
