Explain the appearance of the new telescopic escape device applied to several floors.

Referring to Figures 1 and 2, a preferred embodiment of the telescopic escape device of the present invention is suitable for installation on an outer wall 11 of a building 1 adjacent to an escape exit 10 for human escape. The telescopic escape device comprises: a support unit 2 and an escape unit 3.

The support unit 2 of the embodiment is fixed to the outer wall 11, and the branch The struts 2 cooperate with the outer wall 11 to define a sliding track 21 located below the escape exit 10. The sliding track 21 extends downward along a slope-down direction A, and the angle θ between the slope-down direction A and a horizontal plane B is 35° to 45°, but the height of the floor of the building 1 can be visually observed in actual implementation. The aspect ratio is adjusted, and the angle θ of the present embodiment is specifically 40°.

The support unit 2 includes a platform 22 protruding from the outer wall 11 , a first bracket 23 located below the platform 22 , and a second bracket 24 located below the first bracket 23 . The first bracket 23 and the second bracket 24 are respectively disposed on the outer wall 11 at intervals along the oblique descending direction A. The first bracket 23 has a plurality of extending along the oblique descending direction A and spaced apart from each other. An array of rods 231 (see FIG. 7) having a plurality of rolling circular tubes 241 arranged in the oblique descending direction A and rotatable.

The escape unit 3 of the present embodiment is installed beside the escape exit 10, and can be pivoted relative to the outer wall 11 in a non-use state as shown in FIG. 1 and a use state as shown in FIG. . In the non-use state, the escape unit 3 is installed upright in the escape outlet 10, and the escape unit 3 can pivot to the outside of the escape outlet 10 and then switch to the use state. In this state of use, the escape unit 3 is placed against the platform 22. The escape unit 3 includes a housing 31, a telescopic slide 32, a cushioning member 33, and a pull cord 35 (see Fig. 3).

The housing 31 is pivotally connected to the outer wall 11 for pivoting relative to the escape outlet 10, so that the escape unit 3 can be switched between the non-use state of FIG. 1 and the use state of FIG.

Referring to FIG. 3 and FIG. 4 , the housing 31 forms an accommodating space 310 . The accommodating space 310 is received by the telescopic slide 32 and the cushioning component 33.

Referring to FIG. 4, FIG. 5 and FIG. 6, the telescopic slide 32 is pivotally connected to the housing 31 and has a plurality of carriers 321 that are slidably coupled to each other. Each of the carriers 321 has a chassis 322 and a side guard 323 connected to the chassis 322 and away from the outer wall 11. A plurality of balls 324 are interposed between the carriers 321 and the balls 324 are slidable between the two connected chassis 322, thereby increasing the sliding smoothness between the two connected chassis 322.

Wherein, when the escape unit 3 is in the use state of FIG. 2, the telescopic slide 32 of the escape unit 3 can also be in a folded position as shown in FIG. 2 with respect to the support unit 2, and a deployed position as shown in FIG. Inter-scaling conversion.

Referring to FIG. 2, in the retracted position, the telescopic slide 32 is retracted at the top end of the support unit 2, and the carrier 321 (see FIG. 4) is folded in the housing 31. Next, the telescopic slide 32 can be pivotally shifted to the deployed position of FIG.

Referring to FIG. 3 and FIG. 7 , when the telescopic slide 32 is in the deployed position, the telescopic slide 32 abuts against the support unit 2 , and the support 321 extends downward along the slide rail 21 , and is firstly stretched. The first bracket 23 is supported and continues to project downward, and then the second bracket 24 is touched and deployed downward along the rolling tubes 241. After being fully deployed, the outer wall 11, the chassis 322 and the side guards 323 collectively define a chute 320 that can carry the human body.

The cushioning member 33 is made of elastic foam and is attached to the bottom end of the telescopic slide 32. However, the material or form of the cushioning member 33 is not limited thereto. For example, the spring may be replaced when the carrier 321 is deployed downward. The cushioning member 33 can prevent the telescopic slide 32 from colliding with the foreign object and can be used as a buffering force to prevent the lowermost carrier 321 from being damaged by the impact.

One end of the pull cord 35 is mounted on the lowermost carrier 321 , and the other end is limited to the escape exit 10 . When the pull cord 35 is pulled upward, the carrier 321 is driven upward and merged.

When the present invention is not normally used, the escape unit 3 is placed in the non-use state as shown in FIG. 1 and is concealed in the escape exit 10, and when there is an escape or exercise demand, the escape exit 10 can be taken out from the escape exit 10 The escape unit 3 is pushed open to switch to the use state as shown in FIG. Then, when the escape unit 3 is maintained in the use state, the telescopic slide 32 can be flipped from the retracted position of FIG. 2 to the deployed position of FIG. 3, and the carriers 321 are subjected to gravity. The action automatically extends downward along the sliding track 21 and forms the chute 320 together with the outer wall 11, and then the escaper can enter the chute 320 and slide down to escape.

It should be noted that during the process that the sliding track 21 is automatically extended downward, the rolling tube 241 (see FIG. 7) of the second bracket 24 can assist the movement of the bearing blocks 321 to make the sliding. The extension of the moving track 21 can be smoother. At the same time, the cushioning member 33 installed at the lowermost position protects the lowermost carrier 321 from being damaged by impacting foreign objects during deployment.

On the other hand, when not in use, the pull cord 35 can be pulled from the escape exit 10 such that the carriers 321 are merged and folded up, and then the telescopic slide 32 is turned over to the collapsed position as shown in FIG. The escape unit 3 is then pulled back to the non-use state of FIG. 1 and placed in the escape exit 10.

It is worth mentioning that, referring to FIG. 1 , FIG. 2 and FIG. 3 , when the telescopic escape device of the present invention is switched to the deployed position as shown in FIG. 3 , it is automatically deployed by gravity, and the first bracket 23 and the first bracket In addition to the supporting function, the two brackets 24 can also assist the bearing 321 to smoothly slide and unfold, so that the operation is extremely simple. When the escaper rides on the chassis 322, the slope of the sliding track 21 can be automatically slid and moved without consuming effort for climbing, and the descending process does not waste too much time, which can improve the chance of successful escape. The equal side handle 323 protects the escaper from falling from the side and increases the psychological safety of the escaper. In addition, since the telescopic escape device of the present invention is directly mounted on the outer wall 11 of the building 1, it can be installed without being restricted by the surrounding environment.

It is further noted that the sliding rail 21 of the present embodiment extends downward along the oblique descending direction A, and the angle θ between the oblique descending direction A and the horizontal plane B is preferably 35° to 45°. This is because when the angle θ is greater than 45°, the slope of the slip track 21 is too large, which contributes to the slip of the carrier 321 , but the relative escaper must also slide at a steep slope. It is still easy to cause the fear of the escaper, and the escape speed of the escaper is too fast and dangerous. On the other hand, when the angle θ is less than 35°, the slip speed of the carrier 321 is too slow because the slope is too small, which is not conducive to emergency. Used when escaping.

In addition, the first bracket 23 of the embodiment supports the upper half of the telescopic slide 32, and the second bracket 24 supports the lower half of the telescopic slide 32. The number of the supports 321 of the telescopic slides 32 can be increased or decreased according to the length and height of the actual outer wall 11. The number of the supports of the support unit 2 can also be increased or decreased, and is not limited to the embodiment. An example.

Referring to Fig. 8, in the actual installation of the present invention, a plurality of telescopic escape devices can be respectively installed on the side of several escape exits 10 on different floors, so that the escape units 3 are arranged in a zigzag arrangement when they are deployed. The escaper can move from the escape exit 10 on the upper floor to the lower part to meet the needs of the multi-story building 1.

In summary, the novel telescopic escape device is relatively simple in operation, relatively unaffected by the environment during installation, and is more labor-saving and time-saving for the escaper, so the purpose of the novel can be achieved.

However, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent changes and modifications made in accordance with the scope of the present patent application and the contents of the patent specification, All remain within the scope of this new patent.
