The buffer device 1 is used to set up a so-called temporary shelter for a person in the floor area of a hoistway in which an elevator system 2 is arranged, which performs maintenance or repair work on the elevator system 2. The buffer device 1 is in one Floor area of the elevator shaft below a movable in a vertical direction Z car 3 is arranged. The car 3 is mounted vertically movable in a carrying device 16 of the elevator installation 2. In this case, the support means has two guide rails 23 arranged vertically and parallel to one another for receiving the car 3 and a base element 24 which connects the guide rail in the region of its lower end. The elevator system 2 is designed as a hydro rope elevator.

The buffer device 1 has a base body 4 and a support body 5 mounted pivotably in the base body 4 about a first axis 6. The main body 4 is connected to the base element 24 in the floor area of the elevator installation 2. In this case, the main body 4 rests with a side facing away from the support body 5 on a bottom of the elevator shaft. The support body 5 has, at an end facing away from the axis 6, a first stop surface 7 pointing in a longitudinal direction L of the support body 5 for a lower side 9 of the car 3. This first stop surface 7 serves as a stop for the underside 9 of the car 3 in a first end position of the buffer device 1, wherein in this first end position of the support body 5 is aligned with the longitudinal direction L in the vertical direction Z, thus in this first end position, the first stop surface 7 in the direction of the bottom 9 of the car 3 has. Furthermore, the supporting body 5 has a second stop surface 8, pointing in a vertical direction H of the supporting body 5, for the underside of the car 3. This second stop surface 8 serves as a stop for the bottom 9 of the car 3 in a second end position of the buffer device 1, wherein in this second end position of the support body 5 is aligned with a vertical direction H in the vertical direction Z. In normal operation of the elevator installation 2, the buffer device 1 is in the second end position. In the first end position, however, is formed by the buffer device 1, a temporary shelter for performing maintenance, repair or the like.

The support body 5 has on a side opposite the first abutment surface 7 a first support surface 10 and on a second abutment surface 8 opposite side a second support surface 11, wherein in the first end position, the first support surface 10 contacted a bottom portion 12 of the body and in the second Endstellung the second support surface 11, the bottom portion 12 of the Main body 4 contacted. The base body 4 has two opposite the bottom portion 12 in the vertical direction Z projecting bearing portions 13, wherein the first axis 6 is slidably mounted in a guide 14 of the respective bearing portion 13 between the first end position and the second end position of the buffer device 1. In the present case, the respective guide 14 of the bearing sections 13 is formed by a guide slot passing through the respective bearing section 13, wherein the axis 6 passes through the support body 5 at an end facing away from the first stop face 7 and the guide slot 14 of the respective bearing section 13.

The respective guide 14 has a region formed between the two end positions of the axis 6, which protrudes in the vertical direction Z relative to the regions of the guide 14 in which the axis 6 is in the respective end position. Concretely, the guide is designed such that it has an area that rises from the respective end position in the direction of the other end position in the vertical direction and that there is a horizontally aligned area between this area. Accordingly, this horizontally aligned region of the guide 14 protrudes in the vertical direction Z with respect to the two end regions of the guide 14, in which the axis 6 is in the respective end position of the buffer device 1. This design of the guide 14 allows a simple pivoting and pivoting of the support body 5 at non-planar support of the support body 5, in this case the respective support surface 10, 11, on the base body 4, specifically the bottom portion 12 of the body, in the respective end position.

In order to enable safe and easy handling of the buffer device 1 by a user of the buffer device 1, the buffer device 1 has a drive means 15 driven by a drive for moving the support body 5 from one end position to the other end position. In the present case, the buffer device 1 has an electric cylinder with a rod 22, this electric cylinder with the rod 22, the entirety of actuating means 15 and drive the buffer device 1 forms. An end of the cylinder of the electric cylinder facing away from the rod 22, which forms a bearing housing 21 for the rod 22, is pivotably mounted in the base body 4 in an end of the base body 4 facing away from the guide 14. The rod 22 in turn is pivotally mounted with its end facing away from the bearing housing 21 in the support body 5, specifically, the pivotal mounting of the rod 22 is formed in the support body 5 by a bearing of the rod 22 in the axis 6.

The buffer device 1 has two connecting elements 18, wherein the respective connecting element 18 is pivotally mounted with a first end in the respective bearing portion 13 and is pivotally mounted in the support body 5 with a second end at a distance from the axis 6. The respective connecting element 18 is fixedly mounted in the support body 5 and fixed in the base body 4.

By a method of linearly displaceably mounted in the cylinder of the electric cylinder rod 22, the support body 5 is pivoted about the axis 6 due to the positive guide formed by the connecting elements 18 and also the axis 6 is displaced in the guide 14.

In the present case corresponds in the Fig. 3 shown first end position of the buffer device 1 to a state of the actuating means 15, in which the rod 22 is in a retracted position in the bearing housing 21. The in the Fig. 2 illustrated second end position corresponds, however, to an extended state of the rod 22nd

The electric cylinder with the vefahrbaren rod 22, which forms the actuating means 15 and the drive, is centrally located between the two bearing portions 13 and extends substantially horizontally and parallel to the two bearing portions 13 from the one end of the base body 4 in the direction of the other end In the present case, the two bearing sections 13 protrude in the vertical direction Z with respect to the electric cylinder with the rod 22.

The support body 5 has two extending in the longitudinal direction of the support profiles, wherein the support profiles in a transverse direction Q of the support body 5 are spaced from each other. By the two spaced support profiles, a receptacle 17 for the bearing housing 21 and the rod 22 is formed, wherein the bearing housing 21 and the rod 22 are arranged in the second end position in the receptacle 17. By the receptacle 17, which receives the actuating means 15 and the drive, namely the electric cylinder and the rod 22, the buffer device 1 is made extremely compact despite the actuating means 15 and the drive. Thus, the outer dimensions of the buffer device 1 with drive and adjusting means 15 are identical to a buffer device 1 without actuating means and without drive. In this respect, the adjusting means 15 and the drive, which in the present case are designed as an electric cylinder and rod 22, do not adversely affect the space requirement of the buffer device 1 in the elevator shaft.

In the present case, formed in the longitudinal extent of the support body 5 side surfaces of the support profiles, the second support surface 11. This support surface 11 is flat and extends from the first support surface 10 to the first stop surface 7. In the second end position, this second support surface 11 lies over the entire surface on the bottom portion 12 of the main body 4. As a result, forces acting downward on the second stop surface 8 in the vertical direction Z can be introduced particularly well into the base body 4 and from the base body 4 into a bottom surface 20 of the elevator shaft.

Due to the design of the guide 14 with a vertically projecting area pivoting of the support body 5 from the second end position to the first end position while still full surface support of the support body 5, specifically the support surface 11, on the bottom portion 12 of the body 4 in the second end position allows in that, depending on the specific design, before and / or during the pivoting movement, lifting of the second support surface 11 from the bottom section 12 of the base body 4 in the vertical direction Z takes place upwards.

The first abutment surface 7 and the second abutment surface 8 are each formed by an identically formed, plate-shaped body. How the particular Fig. 8 can be seen, the first stop surface 7 in the first end position and the second stop surface 8 in the second end position in the vertical direction Z are aligned with each other.

In the Fig. 8 the buffer device 1 is shown in three different positions of the support body 5 with respect to the base body 4. In this case, the support body 5 in the first end position, in which the longitudinal direction L of the support body 5 in the vertical Direction Z is formed, and which corresponds to the position of the support body 5, in which a temporary shelter is formed, shown by solid lines. In this first end position of the support body 5 is pivoted by 90 ° relative to the base body 4. In the intermediate position in which the support body 5 is pivoted by 45 ° with respect to the base body 4, and in the second end position, in which the support body 5 rests with its second support surface 11 on the bottom portion 12 of the base body 4, the support body 5 respectively shown with dash-dotted lines. For reasons of clarity of the support body 5 is provided in the second end position with primed reference numerals.

The support body 5 furthermore has a cover plate 19, wherein the cover plate 19 is formed on the side of the support body 5 facing away from the second support surface 11. In the second end position of the buffer device 1, the cover plate 19 covers the main body 4 and the entirety of the electric cylinder and rod 22 in the vertical direction Z from. How the particular Fig. 3 can be seen, the electric cylinder and the rod 22 are completely disposed in the second end position of the buffer device 1 between the support body 5 and the base body 4, wherein the cover plate 19 this entirety in the vertical direction Z, the support profiles the entirety in a first horizontal direction and the body forming the first abutment surface 7 covers this entirety in another horizontal direction, whereby the drive and the adjusting means 15, namely the rod 22 and the electric cylinder, in the second end position of the buffer device 1, in which the buffer device 1 in the normal operation of Elevator installation 2 is located, are particularly well protected from external influences.

In the present case, the carrying device 16 of the elevator installation 2 is designed in such a way that it adjoins the car 3 only on one side of the car 3. The buffer device 1 rests on the bottom surface 20 of the elevator shaft, wherein the base body 4 has a fastening section projecting in the vertical direction Z opposite the bottom section 12, wherein the fastening section is connected to the support device 16, specifically screwed thereto. In the present case, the fastening portion is formed at the end of the main body 4, which also has the guides 14 for the axis 6. Due to the design of the buffer device 1 and the arrangement of the buffer device 1 in the elevator shaft is a horizontal distance of the first abutment surface 7 of the support means 16 in the first end position less than a horizontal distance of the first abutment surface 7 of the support means 16 in the second end position, in which the buffer device 1 forms the temporary shelter.

The supporting of the car 3 on the first stop surface 7 or the second stop surface 8 takes place on account of this design and arrangement in a region of the car 3 facing the carrying device 16.
