RU227213U1 - STROLLER WITH SKI GEAR - Google Patents

Abstract

The utility model relates to vehicles, in particular to baby strollers, and is designed to move on snow, pavement and ground. The technical task of the utility model is to easily transport children along flights of stairs both in residential apartment buildings and in an urban environment, as well as to easily transport children through the snow in the winter season. The technical result consists in simplifying the design of the retractable ski mechanism (runners), reducing the total weight of the stroller with the ski mechanism and increasing the reliability of the device by reducing the risk of failure or wear of the device elements by simplifying the design. A baby stroller with a ski mechanism consists of a seat 1, a backrest 2, a pusher handle 3, a stroller frame 4, a pair of front posts 5 (left and right, not shown in the drawing), a pair of rear posts 6 (left and right not shown in the drawing), on which two pairs of wheels 7 are installed. On the front racks 5 there is a pair of linear actuators 8 with a retractable rod 9. On the rear racks 6 there is a pair of auxiliary cylinders 10 with an auxiliary retractable rod 11 and a position lock 12. To the retractable rod 9 and the auxiliary retractable rod 11 a pair of skis 13 is attached. In turn, in the auxiliary cylinder 10 there is a through hole 14, and in the auxiliary retractable rod 11 there is a through hole 15. On the handle of the pusher 3 there is a control unit with an operating mode switch 16, which is connected to a pair of linear actuators by an electric wire 17. The device operates as follows (when the movement of the stroller is stopped): To switch the stroller to the sleigh ride mode (Fig. 2), it is necessary to switch the operating mode from wheel drive to sleigh ride on the control unit 16 (press the corresponding button). A closed contact through an electrical wire 17 will supply power to a pair of linear actuators 8, as a result of which the movable rod 9 with a fixed pair of skis 13, a pair of auxiliary cylinders 10 with an auxiliary retractable rod 11 will begin to extend until it touches the ground. After this, it is necessary to lower the position lock 12 through holes 14 and 15, thereby fixing the sled mode (Fig. 3). To return the stroller to the wheeled position (Fig. 1), it is necessary to remove the position lock 12, and then on the control unit 16 switch the operating mode from sled to wheeled (press the corresponding button). A closed contact through the electrical wire 17 will supply reverse power to a pair of linear actuators 8, as a result of which the movable rod 9 with a fixed pair of skis 13, a pair of auxiliary cylinders 10 with an auxiliary retractable rod 11 will begin to make a return movement to its final position.

Description

The utility model relates to vehicles, in particular to baby strollers, and is designed to move on snow, pavement and ground.

A baby stroller is known from the prior art (see RF Patent No. 2430850, B62 B 7/04, B62 B 9/12, 2009). This stroller is difficult to use in houses where there are no elevators or special strollers. It is also difficult to use in an urban environment in the absence of ramps on flights of stairs. In winter, this stroller gets stuck in the snow, thereby limiting its scope of use.

Universal runners for four-wheeled baby strollers are known from the prior art (see RF Patent No. 2405703, B62B 9/04, 2008).

This device contains the following disadvantages.

To move this device along forest paths, great efforts must be made, since the runners slide along the steps of the stairs without lubrication, and the runners themselves are made of metal.

The mechanism for extending the runners is quite complex and contains a large number of auxiliary moving elements, thereby further increasing the weight of the device as a whole.

The closest technical solution for the same purpose, (prototype), is the “Baby stroller with a ski mechanism” (see RF Patent No. 164132, B62B 13/18, 2016) which consists of a frame containing front and rear wheel posts, while each wheel stand includes left and right supports connected by a jumper. The ski mechanism contains left and right skis connected to each other by connecting elements, and levers. Each lever is connected at its lower end to a connecting element by means of a hinge, and at its upper end is connected to a jumper by means of a hinge. A position lock is attached to the jumper.

This technical solution has the following disadvantage. The ski extension mechanism is quite complex and contains a large number of auxiliary moving elements, thereby further increasing the weight of the device as a whole and reducing its reliability.

The technical task of the utility model is to easily transport children along flights of stairs both in residential apartment buildings and in an urban environment, as well as to easily transport children through the snow in the winter season.

The technical result consists in simplifying the design of the retractable ski mechanism (runners), reducing the total weight of the stroller with the ski mechanism and increasing the reliability of the device by reducing the risk of failure or wear of the device elements by simplifying the design.

The proposed solution is illustrated by the following figures:

In fig. Figure 1 shows a side view of a baby stroller in wheel mode.

In fig. Figure 2 shows a side view of a baby stroller in sled mode.

In fig. Figure 3 shows the process of fixing the sled run mode.

A baby stroller with a ski mechanism consists of a seat 1, a backrest 2, a pusher handle 3, a stroller frame 4, a pair of front posts 5 (left and right, not shown in the drawing), a pair of rear posts 6 (left and right not shown in the drawing) on of which two pairs of wheels 7 are installed. A pair of linear actuators 8 with a retractable rod 9 are installed on the front posts 5. A pair of auxiliary cylinders 10 with an auxiliary retractable rod 11 and a position lock 12 are installed on the rear posts 6. A pair of auxiliary cylinders 10 with an auxiliary retractable rod 11 and a position lock 12 are mounted. a pair of skis 13. In turn, in the auxiliary cylinder 10 there is a through hole 14, and in the auxiliary retractable rod 11 there is a through hole 15. On the handle of the pusher 3 there is a control unit with an operating mode switch 16, which is connected to a pair of linear actuators by an electric wire 17.

The device operates as follows (when the movement of the stroller is stopped): To switch the stroller to the sleigh ride mode (Fig. 2), it is necessary to switch the operating mode from wheel drive to sleigh ride on the control unit 16 (press the corresponding button). A closed contact through an electrical wire 17 will supply power to a pair of linear actuators 8, as a result of which the movable rod 9 with a fixed pair of skis 13, a pair of auxiliary cylinders 10 with an auxiliary retractable rod 11 will begin to extend until it touches the ground. After this, it is necessary to lower the position lock 12 through holes 14 and 15, thereby fixing the sled mode (Fig. 3). To return the stroller to the wheeled position (Fig. 1), it is necessary to remove the position lock 12, and then on the control unit 16 switch the operating mode from sled to wheeled (press the corresponding button). A closed contact through the electrical wire 17 will supply reverse power to a pair of linear actuators 8, as a result of which the movable rod 9 with a fixed pair of skis 13, a pair of auxiliary cylinders 10 with an auxiliary retractable rod 11 will begin to make a return movement to its final position.
