Description

[Detailed Description of the Invention] This invention is mainly aimed at installing and holding a door jamb detection sensor in a door cushion attached to the door end of a sliding door that has a reopening/closing mechanism on trains, etc. The present invention relates to a holding device for a sensor for detecting scissors.

The above-mentioned sensor S for detecting door jambs is a long object (approximately 1.8 m), and as shown in Figs. The hollow part of the door-end cushion R ₁ or another type of door-end cushion R ₂ installed vertically in the
Q ₁ , Q ₂ are built in, and objects caught between the sliding doors can cause the door end cushions R ₁ ,
When R ₂ and sensor S are pressed, sensor S is turned on, and both sliding doors are re-created based on the signal.

By the way, in order to install the conventional door scissor detection sensor S into the door cushion of each sliding door, first attach the door scissors to a long pedestal B made of sponge rubber or the like, as shown in Fig. Glue the detection sensor S, insert the pedestal B into the cavity _Q1 of the door cushion _R1 , and insert the pedestal B into the inner bottom of the door cushion _R1.
One is the type that is adhesively fixed to _T1 , and the other is the type that is adhesively fixed to T1, and the door jamb detection sensor S is simply inserted into the cavity _Q2 of the door cushion _R2 as shown in Fig. 6.
There is a type that is directly glued and fixed to the inner bottom T ₂ of R ₂ .

However, in the former type that is adhesively fixed via the pedestal B, both the sensor S and the pedestal B have no rigidity, so they are twisted by external force, resulting in a disconnection or a short circuit inside the sensor S. on the other hand,
In the latter type, which is fixed by direct adhesion, it is troublesome to insert the sensor S, which is long and has no rigidity, into the cavity Q ₂ of the long door cushion R ₂ , and furthermore, the sensor S is fixed over its entire length. Crossing over to my doorstep
Gluing and fixing to the inner bottom T ₂ of R ₂ is an extremely difficult task. Therefore, the middle part of the sensor S tends to be incompletely bonded, and the sensor S peels off due to external force and falls, resulting in poor contact between the cushion part C ₂ of the door cushion R ₂ and the sensor S, and the sensor S This may cause detection malfunction.

Furthermore, in both the former and the latter, when replacing the sensor S, it is necessary to cut open the cushion parts C ₁ and C ₂ of the door edge cushions R ₁ and R ₂ and remove the adhesive. Not only was this impossible, but there was also the drawback that the door cushions _R1 and _R2 themselves had to be replaced.

This invention was developed in view of the above points.In other words, this invention allows the sensor for detecting door jambs to be easily inserted and removed within the door cushion. It is an object of the present invention to provide a holding device for a sensor for detecting a door jamb, which can protect the sensor from external force by enclosing the sensor and securely fixing the sensor.

Therefore, this invention is removably attached vertically to the tip of a sliding door having a re-opening/closing mechanism, and has a hollow section continuously formed along the longitudinal direction, and a hollow section of the hollow section. On the inner wall, left and right retaining edges protruding inwardly are formed continuously along the longitudinal direction of the hollow portion, and a door edge cushion serves as a buffer zone between the sliding door and its doorstop, and a rigid It is molded from a material, and is inserted and fixed between the left and right holding edges of the hollow part and the inner bottom surface of the door tip side along the longitudinal direction of the door tip cushion, so that the left and right holding edges can be inserted and removed freely along the longitudinal direction of the door tip cushion. While fixed to the edge, the surface of the sliding door facing the door stop has a sensor holder shaped to enclose and hold a long door jamb detection sensor over its entire length. , a long adhesive tape that fixes the door jamb detection sensor to the sensor pedestal over its entire length, and a long adhesive tape that is press-fitted into the hollow part of the door edge cushion so that the sensor pedestal can be pulled out in the longitudinal direction. The invention is characterized in that it is configured to include a retainer that prevents it from coming off.

Hereinafter, the holding device for a sensor for detecting a door jamb of this invention will be explained with reference to the embodiments shown in FIGS. 1 to 4.

Fig. 1 is a side view of the train E, and the door tip portions 2, 2 of the sliding doors 1, 1 for getting on and off the train E, which have a reopening/closing mechanism, are provided with contact buffer strips to prevent door jamming. Door cushions 3 and 4 are installed vertically in the vertical direction, and both the sliding doors 1 and 1 serve as doorstops for the sliding doors 1 on the other side. The door tip cushions 3 and 4 have a bilaterally symmetrical shape and are similarly attached to the door tip sections 2 and 2.
Specifically, as shown in FIG. 3, the door tip portions 2, 2 are respectively formed with engaging edges 5, 5 which are bent inwardly and extend vertically in the vertical direction. A sliding door frame 6 having a U-shaped cross section is fixed to the inside of the engaging edges 5, 5 so as to extend vertically in the vertical direction, with its open surface facing the closing direction of the sliding door 1. A space 7 surrounded by the sliding door frame 6 and the sliding door frame 6 is an insertion space for a mounting base 9 of door cushions 3 and 4, which will be described later.

Next, I will explain about door cushions 3 and 4.
Since it has a symmetrical shape as described above, one of the door cushions 4 will be described as a representative.

The door tip cushion 4 is made of a highly flexible material such as rubber, and its total length is equal to or slightly smaller than the vertical length of the door tip portion 2, and the door tip cushion 4 is made of a highly flexible material such as rubber. A cushion part 8 that protrudes outward from the tip part 2 and comes into contact with the door stop part 3; and a mounting base 9 that is formed to protrude along the longitudinal direction of the cushion part 8 and is integral with the cushion part 8. It has Between the cushion part 8 and the mounting base 9, left and right mounting grooves 10, 10 are continuously formed along the longitudinal direction of the cushion part 8, and the door end cushion 4 is connected to the mounting groove 10. , 10, and insert the engaging edges 5, 5 of the door tip portion 2 into the sliding door 1.

That is, each insertion length is calculated from the total length L of the cushion portion 8.
The length obtained by subtracting l ₁ and l ₂ is {L−(l ₁ +l ₂ )}. Therefore, the retaining edges 12, 12 are formed by a length {L-(l ₁ + _{l 2 )} } from a position below the upper end of the cushion 8 by a length l 2 .

Next, the sensor pedestal 15 installed in the hollow part 11 of the cushion part 8 will be explained. The sensor pedestal 15 is a long object molded from a rigid hard material, for example, hard vinyl chloride resin.
Its total length is the shape length of the holding edges 12, 12 {L
−(l ₁ + l ₂ )}. This sensor pedestal 15 has opposing outwardly protruding insertion edges 16,1.
6 are formed continuously in the length direction of the sensor pedestal 15. The insertion thickness d of these insertion edges 16, 16
The insertion edges 16, 16 are set so that they can be freely inserted and removed with a slight loose fit between the holding edges 12, 12 of the cushion part 8 and the inner bottom surface 8a of the cushion part 8. Further, the sensor pedestal 15 has a surface opposite to the surface on which the insertion edges 16, 16 are formed, that is, a surface of the sensor pedestal 15 that is opposite to the surface where the insertion edges 16, 16 are formed.
Left and right fixing edges 18, 18 are formed along the length direction of the sensor holder 15 on the mounting surface 17 that faces the door stop 3 when mounted inside. The area from the fixed edges 18, 18 to the mounting surface 17 is shaped to enclose a door jamb detection sensor 19, which will be described below, over its entire length.

Thus, the sensor pedestal 15 described above is inserted into the hollow part 11 from the upper or lower end side of the cushion part 8, and the insertion edges 16, 16 of the sensor pedestal 15 are
is inserted and held between the holding edges 12, 12 and the inner bottom surface 8a.

Next, the door jamb detection sensor 19 fixed to the sensor pedestal 15 will be explained. This sensor 19 is in the form of a tape switch and is arranged opposite to each other, with one and the other switch plates 20 and 20 having substantially the same length as the sensor pedestal 15.
and insulating films 21, 21 provided continuously along the longitudinal direction of the switch plates 20, 20 on the left and right sides between the switch plates 20, 20, and completely covering the switch plates 20, 20. A covering material 22 made of highly flexible sponge rubber or the like, and on one side of the covering material 22, the switch plate 20,
20 and a contact edge 23 formed to protrude along the longitudinal direction.

Therefore, the sensor 19 is always connected to the switch plate 2.
0 and 20 are separated and in the OFF state, and the contact edge 23
By pressing at least a part of the switch plate 20, one switch plate 20 corresponding to that part contacts the other switch plate 20 and is turned on.

The sensor 19 then moves the contact edge 23 to the sliding door 1.
