Description

TECHNICAL FIELD

[0001] The utility model belongs to furniture field, concretely relates to a door stop that can lock door leaf in two directions. BACKGROUND

[0002] Door stop is a device installed on a door leaf to abut against a floor or ground, thereby temporarily locking the door leaf during its opening or closing. Unlike a door stopper that only fixes at the maximum opening position, a door stop can lock the door leaf at any position, thereby preventing the door leaf from opening or closing. For example, in a family with pets or infants, a door stop can be used to fix a bedroom door leaf at a position only slightly open, thereby allowing ventilation or preventing the closed door from pinching fingers.

[0003] The existing door stop generally uses a wedge-shaped piece to act between the floor and the bottom end of the door leaf, or is obliquely supported on the ground (such as the floor), thereby achieving one-way locking, so they usually only need to be fixed on the front and rear surfaces of the door leaf.

[0004] Therefore, it is necessary to develop a new door stop that is easy to install and use and can lock the door leaf in two directions. SUMMARY

[0060] Embodiment One

[0061] The present embodiment relates to a door stop acting on a door leaf to lock the door leaf in both directions, through which the opening and closing of the door leaf can be locked in both directions, so that the door stop can lock the door leaf at any position when the door leaf is opened to the middle, thereby preventing the door leaf from being closed and further opened, which is referred to as the door stop's function of locking the door leaf in both directions.

[0062] As shown in Figures 1-2 , the door stop is composed of two parts, a base 10 and a lock body 20, which are pivotally connected to each other, i.e. the lock body 20 is rotatably pivotally connected to the base 10 around the pivot axis 100 as the rotation axis, the base 10 is used to be fixed to the door leaf, for example by adhesive fixing, so that the base 10 is fixed to the door leaf; the lock body 20 is used to be pivoted to contact the ground to lock when the door leaf needs to be locked, i.e. the door leaf is locked by the contact of the abutting end 204 provided at one end of the lock body 20 with the ground (e.g. floor).

[0063] As shown in Figure 3 , the base 10 is mainly composed of a base body 11 and an extension piece 12, the base body 11 is used to be fixed to the door leaf, preferably to one of the front and rear surfaces of the door leaf, the extension piece 12 is used to be fixed to the lower surface of the door leaf, and the extension piece 12 is movably arranged in the up-down direction relative to the base body 11, wherein the up-down direction refers to the vertical direction parallel to one of the front and rear surfaces of the door leaf (i.e. the up-down direction shown in Figure 3 ).

[0064] In the present embodiment, the base body 11 and the extension piece 12 are both fixed to the door leaf by adhesive, for example, 3M glue is provided on the first surface 101 and the second surface 102 in advance, the user installs the door stop by first removing the back paper (i.e. release paper) of the 3M glue at the first surface 101, and then fixing the base 10 to the front and rear surfaces of the door leaf; then the back paper of the 3M glue at the second surface 102 is removed (of course, it can also be removed at the same time as the release paper at the first surface 101), and the extension piece 12 is adjusted to be displaced upward to approach the lower surface of the door leaf until the second surface 102 is adhered and fixed to the lower surface of the door leaf. In other embodiments, the fixing between the base body 11 and the extension piece 12 and the front and rear surfaces and the lower surface of the door leaf can also be achieved by other known means, for example, by screw fixing; or, only the first surface 101 is fixed, and only the second surface 102 is attached or abuts without fixed connection. In addition, the extension structure of the base 10 can also play a role in adapting to door leaves with different ground clearance.

[0065] The base body 11 is further divided into a fixed seat 111 and a pivot seat 13. The fixed seat 111 is a hollow rectangular seat, and its interior is hollow to form a cavity for the telescopic member 12 to extend and retract within it. The pivot seat 13 protrudes from one side of the fixed seat 111. A first pivot hole 131 is provided on the side wall of the pivot seat 13. A first through hole 132 is provided above the first pivot hole 131 at an appropriate distance. The first pivot hole 131 is located near the middle of the pivot seat 13. The pivot 100 is provided through the first pivot hole 131, that is, a pin (not shown in the figure) is provided in the first pivot hole 131 so that the lock body 20 is pivoted relative to the base 10 around the pivot 100. The first pivot hole 131 is used for the lock pin 23 to be inserted into it when in the retracted state.

[0066] The telescopic component 12 is an L-shaped flat component with an L-shaped side and a certain width in the left and right directions, slightly smaller than the fixing base 111, allowing it to be telescopically movable. The telescopic component 12 can be divided into a vertical arm 121 and a horizontal arm 122, which are integrally formed and perpendicular to each other. The vertical arm 121 is telescopically movable within the fixing base 111, and the horizontal arm 122 is used to fit against or be fixed to the lower surface of the door leaf. The first surface 101 is formed by one side of the fixing base 111, that is, the other side away from the pivot base 13, and the second surface 102 is formed by the upper surface of the horizontal arm 122.

[0067] A first locking member 14 is also provided on the fixed base 111, located below the pivot base 13, for forming a first locking assembly that can be locked or unlocked with the second locking member 15 provided on the lock body 20, thereby locking the door in a first state.

[0068] like Figures 4-6 As shown, the lock body 20 includes a lock housing 21 and a housing cover 22, and a lock cylinder 30 installed within the lock housing 21. The main body of the lock cylinder 30 is housed within the lock housing 21, while the parts that need to be operated are exposed for user operation. After assembly, two rotating arms 211 and an arm cavity 212 are formed at the upper end of the lock body 20. Arm shaft holes 213 are also provided on each of the two rotating arms 211, thereby enabling the lock body 20 to be pivotally connected to the pivot seat 13 by a pin.

[0069] The cover 22 is connected to the lower end of the lock cylinder 30 and seals the lower port of the lock shell 21. The cover 22 is made of soft rubber material, such as rubber, so that when the lock body 20 is rotated to the first state and the door leaf 401 is locked, the cover 22 can deform to store energy and increase friction. The contact end 204 is formed on the surface of the cover 22 and has a number of air cavities 205 to further increase friction and ensure that the door stop can provide sufficient locking force to the door leaf.

[0070] The door stop enables bidirectional locking of the door leaf. This is based on the fact that the lock body 20 is almost vertically pressed against the floor (or ground). Since the cover 22 is made of soft rubber, its deformation can increase the vertical force and improve the lateral friction. Also, since the lock body 20, which is originally pivotally mounted relative to the base 10, is locked by the first locking component and cannot rotate, and the door stop is fixed by adhesive at both the first surface 101 and the second surface 102, since the two surfaces are perpendicular to each other, it can provide sufficient locking force when the door leaf 401 is opened or closed.

[0071] On both sides of the arm cavity 212, i.e. on the two rotating arms 211, a first locking hole 214 is provided for the locking pin 23 to be telescopically and movably installed therein, i.e., the locking pin 23 can be positioned as follows: Figure 4 As shown in the extended state, it can also be retracted to be flush with the surface of the rotating arm 211 after being driven by the lock cylinder 30. Since a first through hole 132 is provided on the side wall of the pivot seat 13, when the lock body 20 rotates to the upper second state, the lock pin 23 engages in the first through hole 132 to lock the lock body 20 in that position, i.e., maintain it in the second state. This achieves the effect of keeping the door stop in the unlocked position. At this time, the lock body 20 faces upwards and is close to the door leaf surface, thus achieving stable storage of the door stop when not in use, and the design is relatively aesthetically pleasing. Figure 1 As shown.

[0072] like Figures 3-4 As shown, a first side opening 202 is formed on the first side of the lock body 20, and a first button 32 is mounted on the first side opening 202, thereby sliding up and down therein to lock or unlock the rotation of the lock body 20 relative to the base 10; a second side opening 203 is formed on the second side of the lock body 20, and a second button 33 is mounted on the second side opening 203 and is sliding up and down therein to operate locking or unlocking the rotation of the lock body 20.

[0073] A second locking member 15 is arranged on the second side surface of the lock body 20 for locking the lock body 20 on the base 10 in the first state, and a first locking member 14 is correspondingly arranged on the base body 11. In the embodiment, the first locking member 14 mainly comprises a protruding member 141 protruding from the lower end of the fixing seat 111, and a first locking hole 142 is arranged through the protruding member 141, and the second locking member 15 comprises a recessed hole 151 recessed on the second side surface of the lock body 20 and a lock tongue 152 movably arranged in the recessed hole 151. When the lock body 20 is rotated to the first state, the protruding member 141 is clamped into the recessed hole 151 and the lock tongue 152 extends into the first locking hole 142, thereby locking the lock body 20. 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 on the lock body 20, and the lock tongue 152 extends into the first locking hole 142 in the direction parallel to the door leaf, so that the locking connection between them cannot be pulled apart to cause accidental unlocking.

[0074] Preferably, the protruding member 141 is integrally formed on the fixing seat 111, and the recessed hole 151 is formed by a third through hole 206 formed on the second side surface of the lock shell 21 and a recessed cavity 301 formed on the lock cylinder 30, so as to allow the protruding member 141 to pass through the third through hole 206 and be assembled into the recessed cavity 301.

[0075] As shown in Figures 5-6 , the lock cylinder 30 comprises a lock cylinder body 31 which is a substantially rectangular member, and the top end of the lock cylinder body 31 has a U-shaped recess and core arms on both sides, the lock post 23 is arranged at the core arms, and the first key 32 and the second key 33 are arranged on both sides of the lock cylinder body 31. The lock cylinder body 31 is composed of a lock cylinder member 310 and an unlocking member 330, the unlocking member 330 is movably arranged up and down relative to the lock cylinder member 310, the first key 32 and the second key 33 are arranged on the unlocking member 330, and a spring (not shown in the figure) is arranged between the unlocking member 330 and the lock cylinder member 310 to make the unlocking member 330 initially in the upper position, and the first key 32 or the second key 33 can make the unlocking member 330 move downward (in the direction from the upper position to the lower position) when it is stressed, thereby driving the lock post 23 to retract and unlock. Figure 6

[0076] As shown in Figure 6 , an installation hole 311 for assembling and movably arranging the unlocking member 330 up and down therein is arranged on the lock cylinder member 310, and clamping protrusions 334 are arranged on the inner and outer sides of the side edges of the unlocking member 330 for clamping on the side walls of the installation hole 311, and the side walls of the installation hole 311 are formed in a strip shape for clamping between the two clamping protrusions 334, thereby realizing the assembly connection and the movably arrangement up and down of the unlocking member 330 relative to the lock cylinder member 310.

[0077] ​The lock tongue 152 is arranged at the upper end of the unlocking member 330 and extends upwardly, and has cavities on both sides of the lock tongue 152 for forming the concave cavities 301. Driving arms 332 are arranged at both sides of the upper end of the unlocking member 330, respectively, for driving the swing member 320 to move and thus drive the lock post 23 to move in and out of the second lock hole 214. The swing member 320 is composed of two symmetrical and opposite swing arm members 321, each of which is rotatably arranged around a pivot axis 340. For example, a swing post 312 is arranged on the lock core member 310, and a swing axis hole 322 is arranged at the middle part of the swing arm member 321, which is sleeved on the swing post 312. Since the two swing arm members 321 are symmetrically arranged, their respective pivot axes 340 are parallel to each other. Preferably, the swing axis hole 322 is arranged at the middle position of the swing arm member 321, the lock post 23 is arranged at the upper end of the swing arm member 321 and can be extended out of the second lock hole 214, and a spring is arranged between the inner side of the lower end of the swing arm member 321 and a spring seat 313 arranged on the lock core member 310, so that the lock post 23 is initially kept extended out of the second lock hole 214. A first contact surface 323 is formed at the outer side of the lower end of the swing arm member 321, and a second contact surface 333 is arranged on the inner side wall of the driving arm 332. When the unlocking member 330 is displaced downwardly 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 axis 340, and the lock post 23 is retracted into the second lock hole 214.

[0078] The installation process of the door stop is as follows:

[0079] Firstly, the door stop is fixed at a predetermined position on the door leaf 401. The position of the door stop is required to be related to the locking function of the door stop in the up-down direction. When fixed, the length of the working section of the lock body 20 is ensured to be greater than the distance from the pivot 100 to the ground, and the length of the working section of the lock body 20 refers to the distance from the end of the lock body 20 to the pivot 100 in the natural state.

[0080] Specifically, one of the following modes can be adopted

[0081] 1. The mounting length of the telescopic member 12 relative to the base 10 is adjusted, so as to control the mounting position of the door stop on the door leaf.

[0082] The user can operate as follows:

[0083] As shown in FIG. 7, the door stop is first adjusted to the first state, and then is attached to the vicinity of the lower end of the door leaf 401, so that the abutting end 204 of the lower end of the lock body 20 is in contact with the ground 402. The telescopic state of the telescopic member 12 is adjusted to retract a certain distance d1 upwardly relative to the base body 11.

[0084] Then, rotate the lock body 20 to a position deviating from the first state, for example, to the second position, such as... Figure 8 As shown, the first surface 101 is glued and fixed to the front surface of the door leaf 401. Finally, the telescopic member 12 is moved upward until the second surface 102 is glued and fixed to the bottom end face of the door leaf, forming a shape as shown. Figure 9 The installation state shown is also the second state (or storage state) of the door.

[0085] 2. Adjustment of other positions

[0086] Of course, when adjusting d1, you can also choose not to attach the door stop to the lower end of the door leaf 401 to be installed for reference operation. Instead, adjust the door stop to the first state and place it vertically on a reference plane (for example, place it roughly vertically on a table), and then adjust the telescopic component 12 to retract upward by the distance d1.

[0087] Alternatively, instead of relying on a reference plane, the upward retraction distance d1 of the telescopic component 12 can be manually adjusted. In this case, appropriate values ​​or positions can be marked on the telescopic component 12. During installation, the user can adjust the telescopic position of the telescopic component 12 according to their own needs and then press... Figures 8-9 Install as shown.

[0088] Alternatively, the structure of the telescopic component 12 can be designed to limit its maximum telescopic distance, and its maximum extension position can be the state after the preset retraction distance d1, that is, no user adjustment function is provided but it is preset at the factory.

[0089] Secondly, after the door stop is fixed, the user can lock the door in both directions by operating the door stop state, as follows:

[0092] To evaluate the actual function of the door stop, a 3D-printed prototype of the door stop from Embodiment 1 was created, and the locking effect of the prototype door stop was tested. 3M adhesive was applied to the first surface 101 and the second surface 102 of the prototype. The test site was a composite floor, and the test door was an inward-opening interior wooden door. The door stop was installed on the front surface of the door.

[0093] Through multiple repeated tests, the following test results are obtained:

[0094] 1. When the retraction distance d1 is 3mm, the locking force measurement data of opening the door are all greater than 30kg, and the locking force measurement data of closing the door are all greater than or equal to 15kg.

[0095] 2. When the retraction distance d1 is 4mm, the locking force measurement data of opening the door are all greater than 30kg, and the locking force measurement data of closing the door are all greater than or equal to 16kg.

[0096] 3. When the retraction distance d1 is 5mm, the locking force measurement data of opening the door are all greater than 30kg, and the locking force measurement data of closing the door are all greater than or equal to 20kg.

[0097] The measurement data list is as follows:
