Abstract

The invention aims to provide an elevator cabin which can prevent water drops from entering extraction parts of cables of an operation plate by using a simple method. In the elevator cabin in the invention, opening parts (13, 13A, 13B) for extracting cables are forms in a side wall of the operation plate (7). And water shields (14, 14-1, 14-2) with downward openings are arranged on an upper part and a side part of the operation plate (7) for covering the opening parts for extracting cables. The cables from the operation plate (9, 9a, 9b) are downwardly extracted from the opening parts for extracting cables and then extend upwardly to connect into a control box (8) of a ceiling plate of the elevator cabin. By adopting the above structure, the water drops dropping from the cables can drop downwardly directly and the water drops dropping along the operation plate can drop downwardly from the water shield. Thus, the water drops can be prevented from entering into the opening parts for extracting cables.

The specific embodiment

Below referring to figs. 1 through Fig. 4 one embodiment of lift car involved in the present invention is described.In addition, with the identical identical member of symbolic representation of symbol among Fig. 7 to Figure 11, and the detailed description of the repetition of omission identical components.

In the present embodiment, the lead division from the cable 9 of operation board 7 is arranged on the sidewall of operation board 7.

As shown in Figure 4, the antetheca 4A that operation board 7 will be adjacent with the sidewall 3 that forms elevator cages is formed with the peristome 13 that cable is drawn usefulness as the part of its member on the part that becomes the operation board sidewall of this antetheca 4A.By on above-below direction, increasing or dwindling the size that this cable is drawn the peristome 13 of usefulness, can regulate the aperture area of this peristome.

Be provided with and cover that this cable is drawn top, side and the top in the outside (outside of elevator cages) of the peristome 13 of usefulness and the elongated end of side is the waterproof case 14 of leading section.As shown in Figure 2, this waterproof case 14 by be formed on described cable draw the flange part 14A that roughly is reverse U shape of the top of peristome 13 of usefulness and the left and right sides side that links to each other with this top, from the top of this flange part 14A and the extended top board 14B of left and right sides side that links to each other with this top and about

side plate

14C, 14D and elongated end seal this top board 14B and about the front end-plate 14E of

side plate

14C, 14D form.By forming waterproof case 14 in the above described manner, obtain in the outside of operation board 7 drawing the top of peristome 13 of usefulness and the waterproof case 14 of sidepiece outwardly from the covering cable that is used for of the side-prominent opening downwards in the inboard of operation board 7.That is to say, the interval W of

side plate

14C, 14D about waterproof case 14 is formed at least at described cable and draws more than the interval of left and right sides side of peristome 13 of usefulness, and the depth size H till front end-plate 14E is set at the size with rich amount on the basis of factors such as the radical of considering the cable 9 that need draw and bendability.Be of a size of the lower end of

side plate

14C, 14D of H and the lower end that is spaced apart the front end-plate 14E of W by depth and form opening 14F, this opening 14F becomes the part under shed of described waterproof case 14.

In addition, the both sides, lower end of the flange part 14A that roughly is reverse U shape of waterproof case 14 are formed with the snap portions 14G that difference of height is S.This snap portions 14G is used for the location when mounted, be specifically, shown in Fig. 3 (b), make this snap portions 14G hook the lower edge that cable is drawn the peristome 13 of usefulness from the inboard of operation board 7, and under this state with this hook the part be that fulcrum rotates waterproof case 14 towards direction shown in the arrow shown in Fig. 3 (c), afterwards shown in Fig. 3 (d), the flange part 14A that roughly is reverse U shape is drawn on the periphery of peristome 13 of usefulness to install by being pressed in cable.

In addition, be formed with tapped bore 14H in the top of the flange part 14A of waterproof case 14, shown in Fig. 3 (d), 14H is screwed into antetheca 4A with screw 15 by this tapped bore, so that waterproof case 14 is fixed.In this structure, because the bottom of waterproof case 14 is by end difference and the flange part 14A clamping of snap portions 14G, so only need to carry out fasteningly just waterproof case 14 to be fixed with the top of 15 couples of flange part 14A of a screw.

In addition, when using waterproof case 14, the radical of the cable 9 that can draw from operation board 7 is subjected to the influence of interval W and the depth size H of Fig. 2 to a great extent.By interval W and depth size H are amplified simultaneously, can increase the quantity of the cable 9 that can draw, if but the W setting is too much at interval, then must strengthen the depth size of the antetheca 4A that takes in operation board 7, and cause the floor area of elevator cages to reduce.Therefore, in the present embodiment, increase the quantity of the cable 9 that can draw by the depth size H that increases waterproof case 14.

Below method that cable 9 is drawn from operation board 7 describe.

Shown in Fig. 3 (a), at first the peristome 13 that cable 9 is drawn usefulness from the cable of the sidewall (antetheca 4A) that is formed on operation board 7 is drawn, and then as mentioned above, waterproof case 14 is installed according to Fig. 3 (b) to the order shown in Fig. 3 (d).Afterwards, as shown in Figure 4, after making the cable 9 of drawing turn over turnback below the waterproof case 14 with being the U word shape towards above extend.After this, as shown in Figure 1, the end that extends to the cable 9 of top is connected in the control box 8.

According to the present embodiment of above explanation, only need set up waterproof case 14, just can prevent that water droplet from invading in the operation board 7.That is to say, because the water droplet that drip along the cable 9 in operation board 7 outsides drips at the sweep 9T place that is formed on below the cable 9 shown in Figure 4, so water droplet can not arrive the peristome 13 that cable is drawn usefulness.In addition, drip the water droplet that gets off along antetheca 4A and will flow to the peristome 13 that cable is drawn usefulness, but because the peripheral end of flange part 14A is formed top and sidepiece greater than peristome 13, and it is fastening and fixing by screw 15 on top, so water droplet can not crossed the inside that the flange part 14A of waterproof case 14 enters antetheca 4A after arriving peristome 13, but drop onto the outside of elevator cages around top board 14B,

side plate

14C, 14D and the front end-plate 14E etc.In addition, in snap portions 14G, because the position of the bottom of

side plate

14C, 14D is formed than the position of the snap portions that engages with peristome 13 and more leans on the below, so can more easily will be directed to the bottom of

side plate

14C, 14D on every side, thereby can prevent more effectively that water droplet is from peristome 13 intrusions along the water droplet that drips of side plate 14C, 14D.Again, if the peripheral position by the lift car inboard of the peristome 13 of flange part 14A and antetheca 4A is arranged to the structure of closed contact, can prevent that then water intrusion from drawing the position between the flange part 14A of the inside side walls of peristome 13 of usefulness and waterproof case 14 to cable, thereby can prevent more effectively that water droplet from invading.

In the present embodiment, by cable 9 is drawn from the upper side of operation board 7, can shorten the length of cable to control box 8., in the present embodiment, waterproof case 14 the position is set as long as be on the antetheca 4A at the sidewall of operation board 7, then can be arranged on the optional position.

, because of the kind that is arranged on parts on the operation board 7 and equipment is different, preferably cable 9 is drawn dispersedly sometimes.At this moment, preferred outgoing cable 9 as shown in Figure 5 and Figure 6.In addition, in Fig. 5 and Fig. 6, the member that the symbolic representation identical with Fig. 1 to Fig. 4 is identical, and omit the detailed description of its repetition.

Be in this variation, to be that the upper and lower of antetheca 4A is provided with a plurality of waterproof case 14-1,14-2 specifically at the sidewall of operation board 7.

By a plurality of waterproof case 14-1,14-2 so are set, can solve following problem.Promptly, in existing cable outbound course shown in Figure 11, because cable concentrates on a cable lead division, occur cable 9 connection errors easily and must make operation board 7 give prominence to or make antetheca 4A distinct issues outside elevator cages significantly significantly towards the lift car indoor in order to take in the cable 9 that concentrates in together so exist., by adopting this variation, then can make the wires design in the operation board 7 have degree of freedom.Be specifically, as shown in Figure 6, the internal wiring 9A of telltale 7A and interface 7B, 9B is via adaptor union 10A, 10B draws the peristome 13A and the waterproof case 14-1 of usefulness and passes through from being arranged on cable between telltale 7A and the interface 7B, and draw as cable 9a as shown in Figure 5, the internal wiring 9C of action button 7C and switch 7D, 9D is via adaptor union 10C, 10D draws the peristome 13B and the waterproof case 14-2 of usefulness and passes through from being arranged on cable between action button 7C and the switch 7D, and draw as cable 9b as shown in Figure 5, the internal wiring that can relax operation board 7 thus concentrates on the phenomenon at a place, thereby can reduce the situation of cable connection mistake.

This variation is except can obtaining the effect identical with above-mentioned embodiment, the internal wiring that can also relax operation board 7 concentrates on the situation at a place, thus, there is no need to make operation board 7 indoor outstanding or make antetheca 4A outstanding outside elevator cages towards lift car because internal wiring too concentrates.
