In the embodiment shown in the figure, the end cover 30 is mainly composed of two parts: a body 32 of the end cover and a tongue-shaped member 34 of the end cover, wherein the body 32 and the tongue-shaped member 34 are preferably made up of a transparent or translucent material, such as made of transparent plastic. Preferably, the tongue-shaped member 34 is formed on one end of the body 32, for example, on a first end, as shown in FIG. 4. Those skilled in the art can be aware of that, the tongue-shaped member 34 may also be located at other locations of the body 32, such as the central part of the body.

(11) In accordance with an embodiment, one or multiple LED lighting lamp(s) 36 are provided in the interior of the body 32, the light of the LED lamp 36 may penetrate the body 32 to illuminate for example a boundary between a comb and a step (the position of the boundary may be known by referring to the boundary between the step 22 and the comb 24 in FIG. 3). Although a certain number of LED lamps are shown in the figure, which are linearly ordered in the substantially central part of the body 32, a larger or smaller number of LED lamps may also be used as needed, which are arranged at any appropriate locations of the body, for example, some LED lamps may be located on the inner surface of the body to enhance lighting. According to a preferred embodiment, the multiple LED lamps are of different colors, to play as a role of further warning. According to another preferred embodiment, the multiple LED lamps of different colors are placed at a certain interval, and the multiple LED lighting lamps flash alternately during the operation for further warning the users.

(12) In accordance with an embodiment, through the cooperation between the tongue-shaped member 34 and at least a part of the anti-clamping device for an apron board in the prior art (see FIG. 6), the end cover 30 can be coupled (for example, be inserted) to one end of the anti-clamping device to form a detachable connection. In addition, the detachable connection can also be implemented in other manners, such as an interference fit connection, a buckling connection, and a bonding connection, to further increase the firmness of the connection between the end cover and the anti-clamping device.

(13) More preferably, the detachable connection is formed on the above-mentioned first end of the body, and the size of the body 32 from the first end to the opposite second end is gradually reduced, so that the end cover can be used as a transition between the apron board and the anti-clamping device (not shown).

(14) According to an embodiment, the body 32 and the tongue-shaped member 34 are formed integrally; and according to another embodiment, the body 32 and the tongue-shaped member 34 are manufactured separately and are connected by means of bonding.

(15) According to an embodiment, as show in FIG. 4B, a through hole or a half-through hole is arranged at the central or other locations of the body 32, and a fastener is inserted into the through hole or the half-through hole to better fix the end cover 30 to the anti-clamping device that is not shown. In addition, the skilled persons can be aware of, a boss, a thread, or other structures in the through hole or the half-through hole, which cooperate with the fastener such as a bolt and a screw, can be arranged to play a better role in locating and fixing.

(16) Preferably, after the installation of the end cover and the apron board protection device is complete, the distance between the end cover and the boundary from the comb to the step is between 50-150 mm, preferably between 60-120 mm, and more preferably 100 mm.

(17) Persons skilled in the art can be aware of that, the shape and material of the above body 32 and the tongue-shaped member 34 are merely illustrative, which may be of any shape and made of any appropriate material that can realize the functions described in this disclosure, for example, the body 32 can accommodate any appropriate number of LED lamps 36 and is transparent, the tongue-shaped member 34 is capable of detachably connecting/coupling with the anti-clamping device for an apron board in the prior art, and so on.

(18) FIGS. 5A-5B are schematic views of the end cover 40 for the anti-clamping device for an apron board configured in double rows according to another embodiment of the present disclosure. In the embodiment shown in FIG. 5, the principle for arranging the body 42, the tongue-shaped member 44, and the LED lamp 46 is substantially the same as that for arranging the end cover shown in FIG. 4, and the difference thereof merely lies in that the embodiment of FIG. 5 is applicable to the anti-clamping device for an apron board configured in double rows, while the embodiment in FIG. 4 is applicable to the anti-clamping device for an apron board configured in a single row. Both the anti-clamping devices for an apron board configured in a single row and in double rows are familiar to persons skilled in the art, and persons skilled in the art, by reading the present invention, can understand how to use the corresponding anti-clamping device to cooperate with the end cover 30 or 40 of the present application, and are able to understand that the discussion and explanation about FIGS. 4A-4B in this disclosure are also applicable to FIG. 5A-5B correspondingly.

(19) FIG. 6 is a schematic view of a cross section of a rigid member 50 of the anti-clamping device cooperated with the end cover in the embodiment of the present disclosure. As described above, the tongue-shaped member 34 of the end cover can cooperate therewith to form a detachable connection. In the embodiment of FIG. 6, the tongue-shaped member 34 is applicable to be inserted into a groove 52, so that the end cover is installed on one end of the anti-clamping device.

(20) Persons skilled in the art can understand that, the specific connection manner between the anti-clamping device and the end cover in the embodiment in this disclosure may differ according to different end covers, so that the detachable connection finally formed between the anti-clamping device and the end cover includes one or more of a plug-in connection, an interference fit connection, a buckling connection, and a bonding connection.

(21) According to the further embodiment of this disclosure, in order to supply power to electronic devices (for example, LED lamps 36 and 46) in the bodies 32 and 42, any existing or future developed manners may be adopted to establish an electrical coupling between the end cover and the anti-clamping device. For example, a wired cable is adopted to connect the anti-clamping device and the end cover, to supply power. For another example, the electrical coupling is established in a wireless manner between the anti-clamping device and the end cover (at this time, a wireless transmit/receive unit may be additionally provided between the anti-clamping device and the end cover) to supply power. In a word, the wired and wireless power supply manners that are well known in the art and developed in the future may be used as the electrical coupling manner between the end cover and the anti-clamping device according to the requirements of actual situations.

(22) Therefore, persons skilled in the art will also be aware of that, the coupling and connection mentioned in the specification and claims not only include various mechanical couplings/connections specifically described above, but also include a wired or wireless electrical coupling. That is to say, the terms coupling and connection ever mentioned in this disclosure should be understood in the most general way according to the context, rather than being explained in a narrow sense.

(23) Persons skilled in the art can further understand that, the features of different embodiments can be used in combination, and all the technical features of the same embodiment are not necessarily reflected entirely in a specific implementation. For example, although the holes can be drilled in the bodies 32 and 42 to promote the fixing between the body and the protection device, in order to save cost and/or meet the requirements such as standardization, it is completely possible to drill no hole or drill one or multiple holes strictly according to the standard size and location. For another example, although the end cover is preferably a plastic material, but any other transparent/translucent material that can meet the safety standards in terms of hardness or the like can also be used.

(24) To sum up, the present written description uses examples to disclose the present invention including an optimal mode, and enables persons skilled in the art to practice the present invention, including the method for fabricating and using any device or system and executing any combination thereof. However, the patentable scope of the present invention can be defined by the claims, and may include other examples that can be thought of by persons skilled in the art.
