The present invention relates to a security device, and more particularly, to a telescopic door stop device.
In recent years, there has been an increasing number of home burglaries, leading to the development of various forms of door security device. The most common anti-theft device involves using a door barricade placed below the doorknob inside the house. Existing door barricades generally consist of a rod, a blocking component, and a support component. The blocking component is positioned to block against the doorknob, while the support component braces against the floor, causing the rod to support at a slight angle between the door and the floor. This prevents the doorknob from being turned, thereby thwarting intruders from unlocking the door from the outside.
The present invention intends to provide a telescopic door stop device to eliminate the shortcomings mentioned above.
The present invention relates to a telescopic door stop device with a rotary connection, and comprises a tube assembly with mutually detachable first tube and second tube. A connecting tube assembly includes a first connecting member connected to the first tube, and a second connecting member connected to the second tube. The first connecting member is detachably connected to the second connecting member. The first connecting member has an engaging part, and the second connecting member has an engaging groove. Two rotational grooves respectively extend from the engaging groove. When the engaging part is inserted into the engaging groove and rotated into the rotational grooves, the first connecting member and the second connecting member are mutually locked in a non-rotatable position to connect the first tube to the second tube. A stop assembly includes a first portion and a second portion respectively inserted into the first tube and the second tube. The first portion includes a door stop element, and the second portion includes a door supporting element.
The primary object of the present invention is to provide a telescopic door stop device which is able to be assembled and disassembled by a rotation operation so as to adjust a length of the telescopic stop device, and also is convenience for storage.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
Referring to
A connecting tube assembly 3 includes a first connecting member 30 detachably connected to the first tube 20, and a second connecting member 31 detachably connected to the second tube 21. The first connecting member 30 has an engaging part 301. The first connecting member 30 has a first base 300. The engaging part 301 and a first connecting part 302 are positioned on two opposite sides of the first base 300 of the first connecting member 30. The first tubular part 302 extends from the first base 300 and is inserted into the first opening 200 so that the first base 300 is abutted against the first opening 200 of the first tube 20, and the engaging part 301 is exposed beyond the first tube 20. The first tubular part 302 includes a first protrusion 3020 protruding outward therefrom. The first protrusion 3020 is inserted into the first fixing hole 201 to connect the first connecting member 30 to the first tube 20. The engaging part 301 of the first connecting member 30 is U-shaped part on the first base 300. The engaging part 301 includes two first segments 303 and a second segments 304 connecting between the two first segments 303. A space 305 is formed between the engaging part 301 and the first base 300.
The second connecting member 31 has a second base 310. The second connecting member 31 has a second tubular part 311 extending from an upper side of the second base 310 and inserted into the second opening 210 such that the second base 310 is abutted against the second opening 210 of the second tube 21. The second tubular part 311 includes a second protrusion 3110 protruding outward therefrom. The second protrusion 3110 is inserted into second fixing hole 211 to connect the second connecting member 31 to the second tube 21. The second connecting member 31 has an engaging groove 313 defined in the second base 310, and two rotational grooves 318 respectively extending from the engaging groove 313. When the second tubular part 311 of the second base 310 and inserted into the second opening 210, the engaging groove 313 together with the two rotational grooves 318 are exposed to the engaging part 301. Specifically, the second base 310 has two plates 312, and the engaging groove 313 is formed between the two plates 312. Each of the plates 312 includes a stepped first stop portion 314 and a second stop portion 315. The thickness of the second stop portion 315 is less than that of the stepped first stop portion 314. The second stop portion 315 has a linear end surface 316 and a curved end surface 317 corresponding to the rotational groove 318. The rotational groove 318 forms a closed end 319 at its end, and the rotational groove 318 communicates with the engaging groove 313.
A stop assembly 4 includes a first portion and a second portion respectively inserted into the first tube 20 and the second tube 21. The first portion includes a door stop element 410, and the second portion includes a door supporting element 400 as shown in
The first connecting member 30 is connected to the second connecting member 31 so that the first base 300 and the second base 310 are in close contact. The engaging part 301 of the first connecting member 30 is inserted into the engaging groove 313 of the second connecting member 31 (as shown in
When adjusting the length of the door stop device 1, press the first and second positioning parts 401, 411 of the first rod 40 and the second rod 41 to release them from the positioning relationship with the positioning holes 202, 212. This allows the first rod 40 and the second rod 41 to move relative to the first tube 20 and the second tube 21. In other words, by positioning the first and second positioning parts 401, 411 in different locations of the first and second positioning holes 202, 212, the length of the first rod 40 and the second rod 41 can be adjusted. Once the desired length is achieved, the door supporting element 400 of the first rod 40 can be braced against the ground “G”, while the door stop element 410 of the second rod 41 can be braced against the door handle “T” (as shown in
It is noted that the structure of the door “T1” of different brands is different, and the distance between the door handle “T” and the ground “G” also varies. Through the above explanation, it is evident that the door stop device 1 of the present invention has a modular design rather than an integrated rod body structure. Therefore, when disassembling the first tube 20 and the second tube 21 of the door stop device 1, both are rotated simultaneously in opposite directions (in this embodiment, the first door tube 20 rotates counterclockwise while the second tube 21 rotates clockwise). This causes the engaging part 301 of the first connecting member 30 to rotate from the position in the rotational groove 318 of the second connecting member 31 to the position in the engaging groove 313, freeing the second segment 304 of the engaging part 301 from the locking relationship with the second stop portion 315 of the plate 312. Once the positional relationship between the first connecting member 30 and the second connecting member 31 is released, the first tube 20 and the second tube 21 can be disassembled. Additionally, users can add a third tube 22 between the first tube 20 and the second tube 21 (as shown in
In addition, an inner wall surface of the second connecting member 31 has an elastic urging assembly 5 positioned relative to the rotational groove 318 and close to the closed end 319. The elastic urging assembly 5 contacts against an outer surface of the second segments 303 of the engaging part 301 to connect the first connecting member 30 to the second connecting member 31. The elastic urging assembly 5 comprises an elastic member 50 and an end member 51. The inner wall surface of the second connecting member 31 includes a receiving groove 3100, the elastic member 50 is received in the receiving groove 3100, and the end clamping member 51 partially protrudes from the rotational groove 318 as shown in
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
