Description

TECHNICAL FIELD

The invention belongs to the field of furniture articles, and specifically relates to a door stop capable of two-way locking of a door leaf, and a method for two-way locking of a door leaf using the door stop.

BACKGROUND

A door stop is a device that is mounted on a door leaf to abut against the floor or the ground so as to temporarily lock the door leaf during its opening or closing. Unlike the door suction which is fixed only at a maximum opening position, the door stop can lock the door leaf at any position, thus preventing the door leaf from opening or closing. For example, in home with pets or infants, a door stop may be used to hold a bedroom door leaf in a position where only a certain gap is opened, thus achieving ventilation or preventing fingers from being pinched by closing.

Existing door stops generally employ wedges that act between the floor and a bottom end of the door leaf, or are diagonally supported on the ground (e.g., the floor) to achieve one-way locking, so they usually only need to be fixed on front and rear surfaces of the door leaf.

Therefore, it is necessary to develop a door stop which is easy to mount and use and capable of achieving two-way locking of the door leaf.

SUMMARY

It is an object of the present invention to provide a door stop mounted at one side of a door leaf and capable of achieving two-way locking of the door leaf, and a method for locking the door leaf using the door stop.

As a first aspect of the present invention, there is provided a two-way locking door stop which can be fixed to a door leaf for two-way locking thereof to prevent opening and closing of the door leaf, including:

• • a base for being fixed to the door leaf, where the base includes a base main body and a telescopic member, the telescopic member is telescopically and movably arranged with respect to the base main body, the base main body is provided with a first surface for being fitted to a surface of the door leaf, and the telescopic member is provided with a second surface for being fitted to a bottom surface of the door leaf;
  • a lock body, where the lock body is rotatably pivoted to the base about a pivot, the lock body is rotatably arranged between a first state and a second state, and the lock body is arranged downward parallel to the first surface in the first state;
  • and a first locking assembly, where the first locking assembly acts between the lock body and the base to lock both or unlock; and the first locking assembly includes a first locking member and a second locking member.

Preferably, the two-way locking door stop is adhesively fixed to the surface of the door leaf at the first surface and adhesively fixed to the bottom surface of the door leaf at the second surface. Alternatively, the base main body is fixed to the surface of the door leaf by screws so that the first surface abuts against the surface of the door leaf, and is adhesively fixed to the bottom surface of the door leaf at the second surface, or the second surface abuts against the bottom surface of the door leaf. Here, when the two-way locking door stop is adhesively fixed at both surfaces, an adhesive can be preset on at least one of the first surface and the second surface, and a user can directly use the adhesive by removing a backing paper.

Preferably, a positioning mechanism or a limiting mechanism is provided on the base, where the positioning mechanism is configured to position a mounting position of the telescopic member when a retraction distance is preset, and the limiting mechanism is configured to provide retraction distances of different values for the user to adjust the mounting position of the telescopic member before mounting. Therefore, the former corresponds to a door stop having a fixed retraction distance d1, and the latter corresponds to a door stop having an adjustable retraction distance d1.

Preferably, the abutting end is made of a soft material to be pressed and deformed in the first state, so that the abutting force can be pressed and deformed to enhance an abutting force, and the soft material can also increase a force of friction with the ground. Preferably, in the first state, the lock body is vertically arranged to be fitted to the surface of the door leaf, so that the lock body is vertically arranged in the first state for locking, which is important for the two-way locking, in which case a locking force in one direction is not too small, and in which case a distance that a lower end of the lock body protrudes from the surface of the door leaf is minimized. Therefore, the door stop is easy to use.

Preferably, the lock body includes a lock case and a case cover, the case cover is made of soft rubber and snapped at an end portion of the lock case, and the abutting end is formed on the case cover; and a plurality of air cavities are provided on an end surface of the case cover. On the one hand, the air cavities can form a negative pressure due to pressing and deformation to increase a contact force; on the other hand, the air cavities can also increase the area of contact with the ground after deformation to increase the force of friction. Here, the air cavities may preferably be composed of hemispherical cavities recessed on a surface of the case cover.

Preferably, the lock body further includes a lock cylinder mounted in the lock case, the lock cylinder is provided with a lock tongue and a first key, a first side of the lock body is provided with a first side port, a second side thereof is provided with a concave hole, the first key is arranged in the first side port, and the lock tongue is arranged at the concave hole. The first locking member includes a convex member convexly provided on one side of the base and a first lock hole penetrating or recessed on the convex member, and the concave hole and the lock tongue constitute the second locking member; and in the first state, the convex member is inserted into the concave hole to cause the lock tongue to extend into the first lock hole to lock rotation of the lock body, and the first key is configured to unlock the lock body from the first state.

Here, the first lock hole may be arranged to penetrate the convex member or recessed on the convex member, the first lock hole is preferably arranged along an axial direction of the lock body, and the lock tongue can be inserted into the first lock hole after the convex member extends into the concave hole, so that the lock body is firmly locked on the base and is not easily pulled apart by force.

According to the two-way locking door stop described above, the second side of the lock case is further provided with a second side port, the lock cylinder is provided with a second key, the second key is arranged in the second side port, and the second key is configured to unlock the lock body from the second state, thus allowing the lock body to rotate to the first state.

According to the two-way locking door stop described above, the lock cylinder is displaceably and movably arranged in the lock body along the axial displacement. That is, the lock cylinder is arranged along the axial direction of the lock body (i.e., a length direction thereof), so that the first key and/or the second key can displace and move along the axial displacement of the lock body to perform unlocking.

Preferably, the base further includes a pivot seat convexly provided on one side of the base main body, and the lock body is pivoted to the pivot seat, for example, by a pin in a penetrating way.

Preferably, the lock body is further provided with a lock column driven by the lock cylinder, the lock case is provided with a second lock hole, the lock column is telescopically and movably arranged in the second lock hole and is driven by the lock cylinder to displace and move to be unlocked, the pivot seat is provided with a first through hole, and in the second state, the lock column can be snapped into the first through hole to lock and hold the lock body.

Preferably, the lock body is further provided with a lock column driven by the lock cylinder, the lock column is arranged in a second lock hole located below an arm shaft hole and is driven by the lock cylinder to displace and move to unlock, and a first through hole is further provided above a first pivot hole.

As a second aspect of the present invention, there is also provided a method for two-way locking of a door leaf, including:

• • providing a door stop having the door stop structure described above, that is, the door stop described above;
  • fixing the door stop to the door leaf, ensuring that a length of a working section of a lock body is greater than a distance from a pivot to the ground during fixing, where the length of the working section of the lock body refers to a distance from an end of the lock body to the pivot in a natural state; and
  • operating the door leaf and the door stop to achieve two-way locking of the door leaf, specifically including: when the door leaf is opened and in a position to be locked, turning the lock body until the end thereof is in contact with the ground and pushing the door leaf toward the door stop to cause the lock body to fit with the base, so that a first locking member is engaged with a second locking member to lock rotation of the lock body.

According to the method described above, when the door stop is fixed to the door leaf, after the lock body is rotated to a first state, the door stop is fitted to the door leaf, a telescopic member is adjusted to be displaced upward with respect to the ground by a predetermined distance, then the lock body is rotated to a second state, a lower end of the telescopic member is positioned close to the ground, and a base main body is mounted to the door leaf, and finally the telescopic member is moved up to fit to a bottom end face of the door leaf. Alternatively, it is also feasible and more convenient that the telescopic member of the door stop is provided with a maximum extension length in advance or a telescoping value thereof is marked. That is, the position of the telescopic member is adjusted with reference to the value of the distance between the pivot of the door stop itself and the end surface of the lock body instead of referring to the door leaf and the ground to control an extension length of the telescopic member or mark numerical change of the telescopic member with respect to a first main body.

According to the method described above, when unlocking is required, the first key is driven to displace to unlock a first locking assembly, and the lock body is rotated to the second state to cause the lock body to fit with the surface of the door leaf, so that the door stop is aesthetically stowed in an unlocked state.

The two-way locking door stop and the method for locking the door leaf of the present invention have at least the following beneficial effects:

• • 1. Only one door stop is mounted at one side of the door leaf to achieve the two-way locking of the door leaf, which solves the shortcoming that the traditional door stop can achieve one-way locking only.
  • 2. The door stop has a compact structure, is easy to mount and use, and can fit the surface of the door leaf for stowage when not in use, and will not be damaged by knocking when opening and closing the door, and is not easy to collide with the human body and hurt people.
  • 3. When the door stop is in the locked state (i.e., the first state), the lock body acts substantially vertically on the floor (i.e., substantially perpendicular to the ground), has a small footprint and is not prone to tripping personnel, and has sufficient locking strength in both directions, without significant lack of strength in one direction.
  • 4. The door stop can be adhesively fixed to the surface and the bottom surface of the door leaf, can provide sufficient locking force for the door leaf in the locked state in combination with its structural relationship and force direction, and the base is a telescopic structure to adapt to door leaves with different ground clearances.

Embodiment 1

The present embodiment relates to a door stop acting on a door leaf to achieve two-way locking of the door leaf, by which opening and closing of the door leaf can be subject to two-way locking, so that the door stop can act on the door leaf when the door leaf is opened to an arbitrary position in the middle, thus preventing the door leaf from closing and further opening, which is called a two-way locking function of the door stop to the door leaf.

As shown in FIGS. 1 and 2, the door stop is composed of a base 10 and a lock body 20 which are pivotally connected to each other, that is, the lock body 20 is rotatably pivotally connected to the base 10 about a pivot 100 as a rotation axis, and the base 10 is configured to be fixed to a door leaf, for example, by adhesive fixing, so that the base 10 is fixed to the door leaf; the lock body 20 is then configured to be pivoted into contact with the ground for locking when the door leaf needs to be locked, that is, the door leaf is locked by abutment of an abutting end 204 provided at one end of the lock body 20 against the ground 402 (e.g., the floor).

As shown in FIG. 3, the base 10 is mainly composed of a base main body 11 and a telescopic member 12, the base main body 11 is configured to be fixed to the door leaf, preferably to one of a front surface and a rear surface of the door leaf, the telescopic member 12 is configured to be fitted and fixed to a lower surface of the door leaf, and the telescopic member 12 is arranged to telescopically movable with respect to the base main body 11 in an up-down direction, where the up-down direction is a vertical direction parallel to one of the front surface and the rear surface of the door leaf (i.e., the up-down direction shown in FIG. 3).

In the present embodiment, both the base main body 11 and the telescopic member 12 are adhesively fixed to the door leaf. For example, 3M adhesive is provided on the first surface 101 and the second surface 102 in advance, and a user firstly removes the backing paper (i.e., release paper) of the 3M adhesive at the first surface 101 during mounting, and then fixes the base 10 to the front surface and the rear surface of the door leaf; and the backing paper of the 3M adhesive at the second surface 102 is then removed (of course, it can also be removed together with the release paper at the first surface 101), and the telescopic member 12 is adjusted to be displaced upward to approach the lower surface of the door leaf until the second surface 102 is adhesively fixed to the lower surface of the door leaf. In other embodiments, the fixing between the base main body 11 and the telescopic member 12 and the front surface and the rear surface and the lower surface of the door leaf may be performed in other known manners, such as a screw fixing. Alternatively, they are fixed at the first surface 101 only and they are fitted to or abuts against the second surface 102 without fixed connection. In addition, a telescopic structure used by the base 10 may also function to adapt to door leaves with different ground clearance.

The base main body 11 is further divided into a first main body 111 and a second main body 112, the first main body 111 is a hollow quasi-rectangular seat body, an interior thereof is hollow to form a cavity for the telescopic member 12 to move telescopically therein, a pivot seat 13 is convexly provided at one side of the first main body 111, a first pivot hole 131 is provided on a side wall of the pivot seat 13, a first through hole 132 is provided above the first pivot hole 131 and at an appropriate distance, the first pivot hole 131 is arranged near a middle portion of the pivot seat 13, and the pivot 100 is arranged in the first pivot hole 131 in a penetrating way, that is, a pin (not shown in the figure) is inserted into the first pivot hole 131 to allow the lock body 20 to be pivoted about the pivot 100 with respect to the base 10, and the first pivot hole 131 is configured to allow the lock column 23 to be snapped thereinto in a stowed state.

The telescopic member 12 is an L-shaped flat member, a side surface thereof is L-shaped, has a certain width in a left-right direction and is slightly smaller than the first main body 111 so as to be telescopically and movably arranged; the telescopic member 12 can be divided into a first arm 1211 and a second arm 1212 which are integrally formed and are perpendicular to each other; the first arm 1211 is telescopically and movably arranged in the first main body 111; and the second arm 1212 is configured to be fitted to or fixed at a lower surface of the door leaf. The first surface 101 is formed by one side surface of the first main body 111, that is, the other side surface away from the pivot seat 13, and the second surface 102 is formed by an upper surface of the second arm 1212.

A first locking member 14 is also provided on the first main body 111, and located below the pivot seat 13 for forming a lockable or unlockable first locking assembly with a second locking member 15 provided on the lock body 20 so as to lock the door in a first state.

As shown in FIGS. 4-6, the lock body 20 includes a lock case 21 and a case cover 22, and a lock cylinder 30 mounted in the lock case 21, where a main body portion of the lock cylinder 30 is housed in the lock case 21, and a portion to be operated is exposed to be operated by a user. After assembly, two rotating arms 211 and an arm cavity 212 formed between the two rotating arms 211 are formed at an upper end of the lock body 20, and arm shaft holes 213 are respectively provided on the two rotating arms 211, so that the lock body 20 is pivotably connected to the pivot seat 13 by a pin.

The case cover 22 is connected to a lower end of the lock cylinder 30 and blocks a lower port of the lock case 21, and the case cover 22 is made of a soft rubber material, such as rubber, so that when the lock body 20 is rotated to the first state to lock the door leaf 401, the case cover 22 can be deformed to accumulate energy and increase a force of friction; and the abutting end 204 is formed on a surface of the case cover 22 and is provided with a plurality of air cavities 205 thereon to further increase the force of friction and ensure that the door stop can provide a sufficient locking force to the door leaf.

The door stop can achieve two-way locking of the door leaf on the basis that the lock body 20 abuts against the floor (or ground) nearly vertically, deformation of the case cover 22 made of soft rubber can increase a vertical acting force and lateral friction, the lock body 20, which is originally pivotably arranged with respect to the base 10 is locked against rotation by the first locking assembly, and the door stop is adhesively fixed at both the first surface 101 and the second surface 102, which provides a sufficient locking force when the door 401 is opened or closed as the two surfaces are perpendicular to each other.

A second lock hole 214 is also provided on both side walls of the arm cavity 212, that is, on the two rotating arms 211, for the lock column 23 to be telescopically and movably arranged therein. That is, the lock column 23 can be in an extended state as shown in FIG. 4, and can also be driven by the lock cylinder 30 to retract to be flush with surfaces of the rotating arms 211. As the first through hole 132 is arranged on the side wall of the pivot seat 13, when the lock body 20 is rotated to an upward second state, the lock column 23 is snapped into the first through hole 132 to lock and keep the lock body 20 in this position, that is, in the second state, thus achieving the effect that the door stop is kept in an unlocked position, and at this time, the lock body 20 faces upward close to the surface of the door leaf, thus achieving stable stowage of the door stop when not in use, and resulting in a relatively beautiful shape, as shown in FIG. 1.

As shown in FIGS. 3 and 4, a first side port 202 is formed on a first side surface of the lock body 20, and the first key 32 is assembled at the first side port 202 so as to be movably arranged to slide up and down therein for locking or unlocking rotation of the lock body 20 with respect to the base 10; and a second side port 203 is formed on a second side surface of the lock body 20, and a second key 33 is assembled at the second side port 203 and movably arranged up and down therein to slide to operate to lock or unlock the rotation of the lock body 20.

A second locking member 15 for locking the lock body 20 to the base 10 in the first state is also provided on the second side surface, while a first locking member 14 is correspondingly provided on the base main body 11. In the present embodiment, the first locking member 14 is mainly composed of a convex member 141 convexly provided at a lower end of the first main body 111 and is provided with a first lock hole 142 arranged in a penetrating manner, while the second locking member 15 is composed of a concave hole 151 recessed on the second side surface of the lock body 20 and a lock tongue 152 movably provided in the concave hole 151. When the lock body 20 is rotated to the first state, the convex member 141 is snapped into the concave hole 151 and the lock tongue 152 extends into the first lock hole 142, thus locking the lock body 20, and since the first locking member 14 and the second locking member 15 are arranged away from the pivot 100, the two locking members have sufficient locking strength to the lock body 20, and the lock tongue 152 extends into the first lock hole 142 in a direction parallel to the door leaf, so that previous locking connection therebetween will not be pulled apart to cause accidental unlocking.

Preferably, the convex member 141 is integrally formed on the first main body 111, and the concave hole 151 is jointly formed by a third side port 206 formed on a second side surface of the lock case 21 and a concave cavity 336 formed on the lock cylinder 30 to allow the convex member 141 to pass through the third side port 206 and be assembled in the concave cavity 336.

As shown in FIGS. 5 and 6, the lock cylinder 30 includes an assembly member which is a quasi-rectangular member as a whole, a top end thereof has a U-shaped recess and cylinder arms located on both sides, the lock column 23 is arranged at the cylinder arms, and the first key 32 and the second key 33 are respectively arranged on both sides of a lock cylinder main body 31. The lock cylinder 30 is composed of a lock cylinder member 310 and an unlocking member 330, the unlocking member 330 is movably arranged up and down with respect to the lock cylinder member 310, the first key 32 and the second key 33 are both arranged on the unlocking member 330, a spring (not shown in the figures) is provided between the unlocking member 330 and the lock cylinder member 310 so that the unlocking member 330 is initially placed at an upper position, and the first key 32 or the second key 33 are forced to displace the unlocking member 330 downward (in the downward direction in FIG. 6), thus driving the lock column 23 to retract and unlock.

As shown in FIG. 6, the lock cylinder member 310 is provided with a first mounting port 311 for the unlocking member 330 to be assembled and movable up and down therein, a first snap protrusion 341 and a second snap protrusion 342 for being snapped onto a side wall of the first mounting port 311 are respectively provided on inner and outer sides of a side edge of the unlocking member 330, and the lock cylinder member 310 is formed as a strip-shaped side wall at the side wall of the first mounting port 311 for being snapped between the first snap protrusion 341 and the second snap protrusion 342 to realize fitting connection and up-down movable arrangement of the unlocking member 330 with respect to the lock cylinder member 310.

The lock tongue 152 is arranged at an upper end of the unlocking member 330 and extends upward. Cavities are provided on both sides of the lock tongue 152 for forming the concave cavity 336; and driving arms 332 are respectively provided at both sides of the upper end of the unlocking member 330 for driving a swing member 320 to move so as to drive the locking column 23 to move telescopically in the second lock hole 214. The swing member 320 is composed of two swing arm members 321 arranged in pairs and symmetrically, and each swing arm member 321 is rotatably arranged with a pivot swing shaft 340 as an axis, for example, a swing column 312 is provided on the lock cylinder member 310, and a swing shaft hole 322 is provided at a middle portion of the swing arm member 321, and the swing shaft hole 322 is sleeved on the swing column 312. Since the two swing arm members 321 are arranged symmetrically, their respective swing axes 340 are parallel to each other. Preferably, the swing shaft hole 322 is arranged at a middle position of the swing arm member 321, the lock column 23 is arranged at an upper end of the swing arm member 321 and can extend from the second lock hole 214, and the spring acts between an inner side of a lower end of the swing arm member 321 and a spring seat 313 provided on the lock cylinder part 310, so that the lock column 23 is initially held extending out of the second lock hole 214. A first contact surface 323 is formed at an outer side of the lower end of the swing arm member 321, and a second contact surface 333 is provided on an inner side wall of the driving arm 332. When the unlocking member 330 is displaced downward under the action of the first key 32 or the second key 33, the second contact surface 333 acts on the first contact surface 323 to rotate around the pivot swing shaft 340, and the lock column 23 is retracted into the second lock hole 214.

The mounting process of the door stop is as follows.

Firstly, the door stop is fixed at a predetermined position on the door leaf 401, where there is a requirement for the fixed position of the door stop is fixed, that is, the fixed position of the door stop in the up-down direction is related to its locking action. When fixed, a length of a working section of the lock body 20 should be greater than a distance from the pivot 100 to the ground 402, and the length of the working section of the lock body 20 refers to a distance from an end of the lock body 20 to the pivot 100 in a natural state.

Specifically, the door stop can be fixed in one of the following ways:

• • 1. A mounting length of the telescopic member 12 with respect to the base 10 is adjusted to control a mounting position of the door stop on the door leaf.

The user can operate as follows.

Referring to FIG. 7, the door stop is first adjusted to the first state, and then fitted to the vicinity of a lower end of the door leaf 401 to bring the abutting end 204 at the lower end of the lock body 20 into contact with the ground 402, and a telescopic state of the telescopic member 12 is adjusted to be retracted upward by a certain distance d1 with respect to the base main body 11.

Then, the lock body 20 is rotated to a position deviating from the first state, for example, to a second position, as shown in FIG. 8, and the first surface 101 is adhesively fixed to a front surface of the door leaf 401. Finally, the telescopic member 12 is displaced upward until the second surface 102 is adhesively fixed to a bottom end surface of the door leaf, forming a mounting state as shown in FIG. 9, which is also a second state (or referred to as a stowed state) of the door stop.

• • 2. Other position adjustment

Of course, when adjusting d1, the door stop may not be fitted to the lower end of the door leaf 401 to be mounted for reference operation, but the door stop may be adjusted to the first state and vertically placed on a reference plane (e.g., substantially vertically placed on a table top), and then the telescopic member 12 may be adjusted to retract upward by the distance d1.

Alternatively, instead of relying on the reference plane, the telescopic member 12 is manually adjusted to retract upward by the distance d1. In this case, an appropriate value or gear position can be marked on the telescopic member 12, and the user can adjust the telescopic position of the telescopic member 12 according to his/her own needs during mounting, and then mount the telescopic member as shown in FIGS. 8 and 9.

Alternatively, the structure of the telescopic member 12 is designed to limit a maximum telescopic distance thereof, and a maximum extension position thereof is a state after it retracts by the preset retraction distance d1, that is, the retraction distance can not be adjusted by the user but is preset at the factory.

Secondly, after the door stop is fixed, two-way locking of the door leaf can be realized by operating the door stop state, and the process is as follows.

In order to operate the door leaf and the door stop to achieve the two-way locking of the door leaf, the door leaf is opened to a position to be locked, then the lock body 20 is rotated until the end thereof is in contact with the ground and then the door leaf is pushed toward the door stop to cause the lock body 20 to fit with the base 10, so that the first locking member 14 is engaged with the second locking member 15 to lock the rotation of the lock body 20, that is, a locked state of the door stop is formed, and the door leaf is locked so as not to be opened or closed.

In addition, when unlocking, the first key 32 is driven to displace to unlock the first locking assembly, and the lock body 20 is rotated to the second state to cause the lock body 20 to fit to the surface of the door leaf, thus achieving unlocking and stowage.

In order to evaluate the actual effect of the door stop, the door stop of Embodiment 1 was subjected to 3D printing to produce a hand board, and the hand board door stop was subjected to locking effect testing. Here, 3M adhesive was applied to the first surface 101 and the second surface 102 of the hand board, the ground 402 of the test place was composite flooring, the door leaf under test was an inward-opening indoor wood door, and the door stop was mounted on the front side surface of the door leaf. The test scenario is as shown in FIG. 10.

By repeating the test a plurality of times, the following test results were obtained:

• • 1. When the retraction distance d1 is 3 mm, the measured locking force of the door opening is greater than 30 kg, and the measured locking force of the door closing is greater than or equal to 15 kg.
  • 2. When the retraction distance d1 is 4 mm, the measured locking force of the door opening is greater than 30 kg, and the measured locking force of the door closing is greater than or equal to 16 kg.
  • 3. When the retraction distance d1 is 5 mm, the measured locking force of the door opening is greater than 30 kg, and the measured locking force of the door closing is greater than or equal to 20 kg.

The measurement data is tabulated as follows:

TABLE 1
Two-way locking force test table
			Door opening	Door closing
	SN	Distance d1	locking force	locking force
	1	3 mm	>30 kg	≥15 kg
	2	4 mm	>30 kg	≥16 kg
	3	5 mm	>30 kg	≥20 kg

It can be seen that the mounting of the door stop of the present invention can achieve the effects that the door opening locking force is greater than 30 kg and the door closing locking force is greater than or equal to 15 kg, which fully satisfies the requirements for the two-way locking of the door leaf in daily life, meets the requirements for this use scenario of the indoor door locking, and the door stop is aesthetically pleasing and easy to mount and operate.
