Abstract

The utility model discloses a foldable folding stair for a lifting attic, which is characterized in that one side of the stair is fixed on a fixed support column of the lifting attic through a spring hinge, and a lockable and foldable folding stair for the lifting attic is formed through a spring bolt arranged at the bottom of a lifting platform support and a spring lock catch plate arranged on the stair corresponding to the installation position of the spring bolt.

Description

Foldable stair with lifting attic

Technical Field

The utility model relates to furniture equipment, in particular to a foldable stair for a lifting attic.

Background

Since cities have a large number of people and the house price is high, and many people buy small house type houses, the using area of the house is too small, and the house space is more effectively utilized, the patent 201820628108.9 discloses a lifting attic invention, when the house needs to be used in practical application, the attic descends, and the space above and below the house is reasonably utilized; when not in use, the loft rises and is folded, and the space of a house is not occupied; the expansion and utilization of indoor space are greatly improved. But the stair of climbing the loft from top to bottom is fixed places the one side at the lift loft, rises at the lift loft, when not using the loft to climb from top to bottom, and the idle placing of stair can additionally occupy a part of living space and can't accomodate and bring inconvenience for the life.

Disclosure of Invention

In order to solve the problems, the utility model provides a foldable lift-loft stair which is fixed on one fixed support column of a lift-loft through a hinge, and can be locked and folded for use through a spring bolt arranged at the bottom of a lift platform support of the lift-loft and a spring lock buckle plate arranged on the stair corresponding to the installation position of the spring bolt.

Has the beneficial effects.

When the lifting platform support provided with the spring lock tongue descends and needs to climb up and down by using a stair, the stair fixed on one fixed support column in the lifting attic through a hinge is manually pulled, the stair rotates by taking the hinge as an axis, and the spring lock catch plate is arranged at the corresponding position below the position where the spring lock tongue is arranged on the lifting platform support of the lifting attic; when the stairs rotate the spring locking buckle plate by taking the hinge as an axis to reach the corresponding position below the position of the spring locking tongue installed on the lifting platform bracket, the stairs are locked and fixed so as to climb up and down conveniently; when the lifting platform bracket of the lifting attic rises, the climbing up and down of the stairs is not needed any more; along with the ascending of the lifting platform support of the lifting attic, the spring lock tongue arranged at the lower part of the lifting support is separated from the spring lock catch plate and does not lock the staircase any more. The stairs can rotate, fold and be fixed at one side of the lifting loft bracket along the hinge as an axis; the occupation of the staircase on the indoor space is saved.

Detailed Description

The latch plate 2 shown in figure 6 is mounted on a staircase 4 shown in figure 1, the staircase 4 being fixedly mounted on the inside of the attic prop 1 by two spring hinges 5.

Further, as shown in fig. 6, the spring bolt 6 is installed at the bottom of the lifting platform bracket 3 as shown in fig. 2 with the bolt sliding side inward, and the installation position of the spring lock plate 2 corresponds to that of the unfolded stair 4;

further, as shown in fig. 3, when the lifting platform support 3 of the lifting attic descends to a set use height and the lifting platform support needs to climb up and down by using the stair 4, the stair 4 is pulled manually, and one side of the stair 4 is fixed on the lifting attic prop 1 through two spring hinges 5 respectively, and at the moment, one side of the stair 4 rotates by taking the spring hinges 5 as an axis; when the spring lock catch plate 2 arranged on the stair 4 rotates to the corresponding position below the spring lock tongue 6 arranged at the bottom of the lifting platform bracket 3. The spring bolt of the spring bolt 6 is inserted into the spring lock buckle plate 2 in a sliding way; locking stair 4 for stair 4 can not receive external force to remove, and the climbing is gone up and down to convenient to use stair 4.

Further, as shown in fig. 1, when the lifting platform support 3 of the lifting attic rises and does not need to climb up and down by using the stairs 4; along with the ascending of the lifting platform support 3, the spring lock buckle plate 2 arranged on the stair 4 is not locked by the spring lock tongue arranged at the lower part of the lifting platform support 3 any more; at the moment, the stairs 4 are automatically rotated and folded towards the inner sides of the lifting loft pillars 1 under the action of the springs fixedly arranged in the spring hinges 5, so that the occupation of the stairs on indoor space is saved.

Example 2 of a folding attic.

As shown in fig. 4, the latch plate 2 shown in fig. 6 is installed on the staircase 4, one side of the staircase 4 is fixedly installed on the inner side of the attic prop 1 by the hinge 7 shown in fig. 6, and the other side of the staircase 4 is connected with the attic prop 9 by the spring 8.

Further, the sliding side of the spring bolt 6 shown in fig. 6 is mounted inward at the bottom of the lifting platform support 3 shown in fig. 2, and the mounting position of the spring shackle plate 2 corresponds to the mounting position of the spring shackle plate 2 after the stairs 4 are unfolded.

Further, as shown in fig. 5, when the lifting platform support 3 of the lifting attic descends to a set use height and the lifting platform support needs to climb up and down by using the stair 4, the stair 4 is pulled manually, and because one side of the stair 4 is fixed on the lifting attic support 1 through two hinges 7 respectively, the stair 4 rotates by taking the two hinges 7 as an axis; when the spring lock catch plate 2 arranged on the stair 4 rotates to the corresponding position below the spring lock tongue 6 arranged at the bottom of the lifting platform bracket 3. The spring bolt of the spring bolt 6 is inserted into the spring lock buckle plate 2 in a sliding way; locking stair 4 for stair 4 can not receive external force to remove, and the climbing is gone up and down to convenient to use stair 4.

Further, as shown in fig. 4, when the lifting platform support 3 of the lifting attic rises and does not need to climb up and down by using the stairs 4; along with the ascending of the lifting platform support 3, the spring lock buckle plate 2 arranged on the stair 4 is not locked by the spring lock tongue arranged at the lower part of the lifting platform support 3 any more; at the moment, the stairs 4 are under the action of the tension of the springs 8 fixed between the lifting loft pillars 9 and the stairs 4, and the stairs 4 rotate and fold towards the inner sides of the lifting loft pillars 1 along the axes of the hinges 7, so that the occupation of the stairs on indoor space is saved.
