Detailed Description

It is to be noted that the structural composition, features and advantages of the elevator car roof protection device, the elevator car and the elevator system according to the utility model will be described below by way of example, but all the description should not be taken to limit the utility model in any way.

In this document, the technical terms "first" and "second" are used for distinguishing between similar or identical items and not for the purpose of indicating the order or relative importance of the same. Furthermore, to the extent that any individual feature described or implied in the embodiments set forth herein, or any individual feature shown or implied in the figures, the utility model still allows any combination or deletion of such features (or equivalents thereof) without any technical hurdle, and further embodiments according to the utility model are considered to be within the scope of the disclosure herein. In addition, for the sake of simplicity of the drawing, identical or similar parts and features may be indicated at one or more places in the same drawing, or some structures may be shown in simplified form in the drawing.

The utility model firstly provides an elevator car roof protection device which is used for being arranged at the top of an elevator car to play a role in safety protection, is very suitable for installation, application and configuration requirements of different elevator cars, and has overall cost advantages. Referring to one embodiment of an elevator car roof guard shown in fig. 1-6, the general situation when the present arrangement is sized is exemplarily illustrated by these figures.

In particular, the elevator car roof guard 100 may be provided with a plurality of guardrails, such as the guardrails shown in fig. 1 and 4 at different locations on the car roof, which are connected to define an operation protection area that meets the requirements of a specific application, so as to provide for equipment maintenance, test observation, etc. to be performed in the area by maintenance staff, etc. to thereby perform a safety protection function and avoid unexpected events such as high-altitude falling.

As an example, in the elevator car roof protection device 100, the first guardrails 11 and the second guardrails 12 are disposed on the left and right sides of the car roof, respectively, i.e., they are disposed opposite to each other along the first direction D1 (generally the longitudinal direction of the elevator car) shown in fig. 1, while the third guardrails 13 are disposed in connection therebetween along the second direction D2 (generally the transverse direction of the elevator car), so that the work protection area 10 having the entrance 10a can be defined. Of course, in some applications, the work protection area 10 may be provided with a closed configuration by adding guardrails, or a configuration with a door operable to open or close at the entrance location, as the utility model is not limited in this regard.

For each individual railing, one or more crossbars may be configured as needed for protection, support, etc., and one or more uprights may be configured for mounting, stiffening, strengthening protection, etc., for example, the first railing 11, the second railing 12, the third railing 13 may be configured with the appropriate number of crossbars 111 and uprights 112, crossbars 121 and uprights 122, crossbars 131 and uprights 132, respectively, as needed, which may be made of round steel pipe, etc., in terms of the specific size, configuration, connection, and materials used for the respective crossbars and uprights, allowing for setup as needed for the application. The first rail 11 can be secured to one side of the car roof by means of one or more uprights 112 in the first rail 11 and the second rail 12 can be secured to the other side of the car roof by means of one or more uprights 122 in the second rail 12. In some embodiments, one or more of the uprights 132 on the third rail 13 may be secured to the top of the car, or the uprights 132 may not be provided to simplify construction. As an alternative, the first 11 and the second 12 guardrails may be arranged both to form a symmetrical arrangement on the car roof with respect to the third guardrail 13.

Unlike the prior art, the first adjusting member 20 is configured in the elevator car roof protection device 100, and the third rail 13 can be detachably connected with the first rail 11 and the second rail 12 by the first adjusting member 20, so that the elevator car roof protection device 100 can perform the length adjustment operation in two different directions, namely, the first direction D1 (i.e., the length direction of the cross bar in the first rail or the second rail) and the second direction D2 (i.e., the length direction of the cross bar in the third rail), and thus the size and layout setting of the operation protection area 10 can be adjusted and changed so as to meet various possible different configuration requirements. It should be appreciated that the first adjustment members 20 used throughout the elevator car roof guard 100 may or may not have the same configuration as one another, and that numerous embodiments of the first adjustment members 20 may be provided in accordance with aspects of the present utility model.

As an exemplary illustration, the first adjuster 20 may be provided to include a first component 21 and a second component 22 that may be coupled together using a coupling 40, such as a bolt, screw, or the like. Of course, in some applications, the two components may be integrally formed, for example, using casting, machining processes, and the like. For the first member 21, the matching portion 211 thereof can be matched-connected with the first rail 11 and the second rail 12, thereby achieving the effect that these rails can be length-size-adjusted in the first direction D1 shown in fig. 1. The connection between the first rail 11 and the first member 21 will be described below by way of example, the description applies equally to the second rail 12.

Referring to fig. 1, 2, 7, etc., the mating portion 211 may be configured to have a portion extending along the first direction D1 (e.g., using a groove structure, etc.), and one or more mounting holes 212 (e.g., using a waist-shaped hole, two or more round holes, etc.) may be provided in the portion, such as on a side and/or bottom of the portion, so that two or more connection locations may be provided for a mounting connection between the first rail 11 and the first member 21, respectively. In one application, one end of the first rail 11 (more specifically, the end of the cross bar 111 facing the first member 21) may be attached along the first direction D1 to one of the attachment locations provided by the mating portion 211, such as by removably inserting the end into a groove structure provided in the mating portion 211 (or alternatively, in some embodiments, inserting the mating portion 211 into the end) and positioning the end at that attachment location, which may cause the first rail 11 to assume a length dimension, such as shown in fig. 1-3. In another application, the end of the first rail 11 may be attached along the first direction D1 to another attachment location provided by the mating portion 211, such as the telescoping variable length configuration shown in fig. 4-6, to allow the first rail 11 to assume another length dimension. Thus, by adjusting the connection fit between the first rail 11 and the first part 21, the elevator car roof guard 100 can be provided with a varying dimensional configuration in the length direction of the first rail 11, e.g. optionally being larger or smaller, so that a first rail 11 with an adjustable length can be realized.

It will be appreciated that when the two connection positions described above are just the upper or lower limit of the adjustable positions, any selective adjustment of the allowable length of the first guard rail 11 between the maximum adjustable length and the minimum adjustable length corresponding to the two limit positions can be achieved by providing a structure such as a waist-shaped hole having a certain length on the matching portion 211 and fixing it with the connection member 40 after the position selection is in place. Further, a stopper 210 may be provided on the first member 21, for example, at an end position of the mating part 211 or the like, so that the relative position between the first rail 11 and the mating part 211 may be restricted by the stopper 210 when the position adjustment operation is performed on the first rail, thereby facilitating the operation.

In this way, with the above arrangement, the elevator car roof protection device 100 can be advantageously promoted to have many possible length dimension configurations in the direction of the above first guardrail 11, so as to fully satisfy more different application requirements, bring great convenience to the guardrail members in management, manufacturing, storage, transportation, maintenance and the like, and help reduce the overall cost.

For the second member 22, please refer to fig. 1, fig. 2, fig. 8, etc. in combination, it may include a connection portion 220 and an adapting portion 221. The second member 22 and the first member 21 may be coupled together by the coupling portion 220, for example, as an alternative, the coupling 40 may be used to secure the second member 22 and the first member 21 via one or more mounting holes 223 provided in the coupling portion 220 and mounting holes 212 or other suitable structures such as mounting holes in the second member 22.

The third rail 13 is matingly coupled to the second member 22 via the mating portion 221 and is further coupled to the first rail 11 (or the second rail 12) via the first member 21 coupled to the second member 22, and more particularly, the respective rails of the rails are interconnected to form a rail assembly. By means of a mating connection with the second part 22, adjustability of the third rail 13 in its length direction (i.e. in the second direction D2) can be achieved. The matching portion 211 in the first member 21 has been described above, and the fitting portion 22 may be constructed identically or similarly thereto, for example, the fitting portion 221 may be constructed to have a portion extending along its length direction, and mounting holes 222 such as waist-shaped holes, a plurality of single holes, etc. are provided on the portion for providing two or more connection positions, thereby allowing two or more configuration choices to be provided when length-size adjustment is performed from one end of the third rail 13, and if length-size adjustment is performed from both ends of the third rail 13 at the same time, a configuration choice capable of achieving a greater length-size range to be provided, thereby being suitable for a wider range of application configuration requirements. Regarding the fitting arrangement between the third rail 13 and the mating part 221 on the second member 22, reference may be made to the corresponding description above regarding the first rail 11 (or the second rail 12) and the mating part 211 on the first member 21, for example, the mating part 221 may be optionally configured as a groove structure or the like, and thus will not be described again.

As a further alternative, the elevator car roof guard 100 may be provided with further adjustment members 30 which may be of, for example, the same or similar construction as the first part 11, e.g. the adjustment members 30 may be provided with mating portions 301 in the form of grooves for providing two or more different mounting connection locations for the guard rail. Such an adjustment member 30 may be removably attached to the other end of the first or second barrier 11, 12, i.e. the end facing the entrance 10a of the work protection area 10, as desired, which is shown exemplarily in the figures of fig. 1 and 4, etc., for example in fig. 4, showing a further telescopic extension that can be provided when desired by means of the adjustment member 30, a relatively longer length arrangement possible than in the assembled situation shown in fig. 1 may be achieved. In this manner, the use of multiple adjustment members in combination allows for greater configuration options for the length dimension of the guardrails, further enhancing the use of configuration functions for the elevator car roof guard.

As described above, since the present elevator car roof protection device allows for length dimension adjustability in two different directions, such as the lateral and longitudinal directions, and a wide range of various length configurations can be achieved by optimizing the configuration, it is possible to cover a considerable number of series product models with only one device over the prior art, effectively solving the problems and adverse effects in the aspects of number management, storage, manufacturing, transportation, maintenance, etc. due to the numerous configuration members of the existing guardrail products, contributing to improvement in efficiency and saving in cost, and thus being suitable for wide application.

The utility model further provides an elevator car and an elevator system. In particular, the proposed elevator car roof protection according to the utility model can be mounted on top of an elevator car, which, due to its strong practicality and wide applicability, allows the elevator car to be of a multitude of applicable types. One or more elevator cars as described above may be provided in the elevator system of the utility model, with which elevator cars are moved up and down in the elevator shaft for carrying passengers, goods or pets etc., and when maintenance management of the elevator installation is required, workers can enter the top of the elevator car and enter the working area defined by the guardrails for operation, at which time their safety protection can be provided by the elevator car roof protection.

The elevator car protection device, the elevator car and the elevator system according to the utility model have been described in detail above by way of example only, which are given for the purpose of illustrating the principles of the utility model and its embodiments, without limitation to the utility model, and various modifications and improvements may be made by those skilled in the art without departing from the scope of the utility model. Accordingly, all equivalent arrangements should be considered to be within the scope of the present utility model and as defined in the claims.
