Description

Multi-environment compatible crib

Technical Field

The utility model relates to an infant's articles for use field especially relates to a compatible crib of multi-environment.

Background

The crib is bedding designed for the sleeping characteristics of the baby, and generally has higher safety and comfort. Taking the guard bar of the crib as an example, in order to ensure the safety of the baby, the guard bar generally surrounds the crib in the whole circumferential range without leaving gaps, and the height of the guard bar is generally larger than the height of the baby in the kneeling state, so as to prevent the baby from falling off over the guard bar, and in addition, the material of the guard bar is coated with soft material through having round corners, so that the influence on the body of the baby due to the rubbing of the baby and the guard bar is prevented.

Safety is usually the requirement that the crib needs to meet first, and on the basis of meeting the safety of the baby sleeping, the crib is developed with other functions to help people take care of the baby. The most typical function is a moving function, and the baby crib can be flexibly moved by additionally arranging the wheel body at the bottom of the baby crib, so that people can always keep the baby crib in the visual range of the people, and the requirements of a baby can be conveniently responded at any time. Secondly, the height adjustment function also can greatly enhance the convenience of people for looking after the baby, and people tend to adjust the height of the crib to the comfortable range of self-nursing actions under different scenes of feeding, sanitary nursing, outgoing activities and the like.

The existing related crib is often difficult to continuously ensure the safety of the crib when the crib has the functions of movement and height adjustment. Specifically, while the moving function is achieved, the crib often needs to have excellent braking capability or staying capability, so that the crib is maintained in place during the process that a caregiver leaves for a short time, and the safety of the baby carried by the crib is ensured. The brake function of the existing crib is often completed through a brake component which interacts with a wheel body, and the typical brake component comprises a brake rope and a friction piece, and the friction piece is pressed against a corresponding structure on the wheel body through pulling of the brake rope, so that the crib is stopped; in addition, through the cooperation relation between brake block and the brake tooth, set up the brake tooth in the wheel body, control the brake block and with the mutual block of brake tooth through brake rope or other transmission to the locking crib.

The conventional brake assembly provides braking force for the baby crib by depending on the friction between the wheel bodies and the ground, so that the phenomenon that the safety of the baby crib is affected by the skidding of the wheel bodies on uneven, inclined or rainy and snowy road surfaces easily occurs. The existing brake component depends on the active braking action of a guardian of the baby on the crib, namely, the brake component is controlled to actively brake through a button, a pull rod or other modes, when the guardian is lack of alertness or distraction, the control on the crib is easily separated in a state of not actively braking, and further safety accidents are caused.

In addition, the crib with height adjustable function is easy to interfere with the reliability of the brake function structurally, taking the brake form of the conventional manual control brake assembly as an example, no matter the brake handle or the button is pulled or pressed, a transmission assembly with a certain length is required to transmit the brake command from the handle end to the wheel body end, and the transmission assembly designed based on the standard height may have lower sensitivity and operability under different height states, thereby reducing the safety of the crib.

The technical solution provided by the present invention is explained in more detail with reference to fig. 1 to 28.

As shown in fig. 1, an embodiment of the present invention provides a multi-environment compatible crib, including:

a bed assembly 1;

one end of the support component 2 is connected with the bed body component 1;

the wheel body component 3 is connected to the other end of the supporting component 2; and

the brake component 4 can realize the brake function of the baby crib through the direct contact between the brake component and the ground.

As shown in fig. 2 to 3, the brake assembly 4 can generate friction force in a manner of directly contacting with the ground through itself, rather than indirectly generating friction force with the ground through acting on the wheel body assembly 3, so that the situation that the baby crib is easy to slide due to incapability of braking due to insufficient wheel body grip in a complex environment is avoided.

In addition, as shown in fig. 10, the brake assembly 4 directly contacts with the ground, and an anti-slip pad with a friction force stronger than that of the wheel body material can be arranged in a partial contact area of the brake assembly 4 and the ground, so that the friction coefficient between the crib and the ground is larger, and the safety factor of the crib is improved.

As shown in fig. 4 to 7, as the optimization of any technical solution or any optimized technical solution provided in the foregoing or in the following of the present invention, the brake assembly 4 includes:

the brake seat 41 is arranged on one side of the support component 2 and/or the wheel body component 3 away from the bed body component 1, and the extension length of the brake seat relative to the support component 2 in the direction away from the bed body component 1 is adjustable, so that the baby crib can be in a braking state or an unlocking state respectively; and

and a brake handle 42 which is arranged on the bed body component 1, is connected to the brake base 41 in a transmission manner, and can control the extending length of the brake base 41 relative to the support component 2.

On this basis, the utility model discloses further through set up in bed body subassembly 1 brake lever 42, it is long-range right the stretching out and the withdrawal action of brake seat 41 are controlled to make things convenient for baby's caregiver to brake or unblock operation to the crib.

Further, for making the crib that the utility model provides regard as conventional state with brake state, as the utility model discloses in the foregoing or any technical scheme that provides hereafter or the optimization of any technical scheme after optimizing, brake subassembly 4 still includes:

a first elastic member 43, one end of which is connected to the brake base 41 and the other end of which is connected to the support assembly 2 and/or the wheel assembly 3, and which can provide an elastic force for the brake base 41 away from the bed assembly 1; and

and the second elastic element 44 is arranged between the brake handle 42 and the bed body assembly 1 and can provide elastic force for the brake handle 42, so that the brake handle 42 has a movement tendency of braking the crib when external force is not applied.

As shown in fig. 13 to 14 and 15 to 16, the first elastic member 43 and the second elastic member 44 may be springs, and are respectively used to position the brake holder 41 and the brake handle 42 corresponding to the braking state of the crib, so that even if a caregiver of an infant forgets to perform a braking operation on the crib in time, the crib can be automatically braked to ensure the safety of the infant.

In the process of automatic braking, the brake base 41 will receive the elastic force from its own weight and the first elastic member 43 at the same time, so as to be attached to the ground in a butting manner, and have a friction force stronger than that under the action of simple gravity.

The first transmission member 45 can transmit the command of the brake handle 42 to the brake holder 41 by its own rotation. Compared with a telescopic motion transmission mode, the first transmission piece 45 adopting a rotary motion occupies less space, has better reliability and quicker transmission process, and can further enhance the controllability of the brake handle 42 on the brake base 41.

As shown in fig. 8 to 9, as the optimization of any technical solution or any optimized technical solution provided in the foregoing or in the following of the present invention, the brake assembly 4 further includes:

As shown in fig. 11 to 14, as any technical solution or any optimized technical solution provided in the foregoing or in the following of the present invention, the brake assembly 4 further includes:

a linkage structure 47, one end of which is rotatably disposed at the second end of the first transmission member 45, and the other end of which is disposed with a first connection point for connecting the second transmission member 46;

the linkage structure 47 can change the distance between the first connection point and the rotation axis of the first transmission member 45 in the process of rotating along with the first transmission member 45.

As shown in fig. 11, the influence of the rotation of the first transmission member 45 on the length of the second transmission member 46 is more significant as the eccentric distance increases based on the second transmission member 46 disposed eccentrically to the rotation axis of the first transmission member 45. Based on this, the utility model discloses further pass through linkage 47 has improved second driving medium 46 equivalent connection to first driving medium 45's tie point distance the eccentricity of first driving medium 45 axis of rotation makes first driving medium 45 can just enable under less turning radius and angle brake seat 41 realizes brake state and unblock state's conversion.

The linkage structure 47 is further hinged to the first transmission piece 45, so that during the rotation of the first transmission piece 45, the eccentric distance of the connection point of the second transmission piece 46 on the linkage structure 47 relative to the rotation axis of the first transmission piece is further enlarged through the rotation of the linkage structure 47 relative to the hinge point.

As shown in fig. 12, the first transmission member 45 having a cylindrical structure and the linkage structure 47 having a circular arc sheet structure can be attached to each other through the respective circular arc peripheral surfaces, and particularly when the baby crib is in a braking state, the inner circular arc of the linkage structure 47 will cover the cylindrical peripheral surface of the first transmission member 45, so that the structure of the brake assembly 4 is more compact.

As shown in fig. 8 to 9, as any technical solution or any optimized technical solution provided in the foregoing or the following paragraphs of the present invention, the second transmission member 46 is a rope-shaped structure, and one end connected to the linkage structure 47 has a stop end with a radius larger than that of the rope-shaped structure, the linkage structure 47 has a pass structure 471 at the first connection point, and the radius of the pass structure 471 is larger than that of the rope-shaped structure and smaller than that of the stop end, so as to provide a pulling force towards the first transmission member only for the second transmission member.

Since the brake holder 41 is to be kept in the braking state by the elastic force of the first elastic member 43, and the brake holder 41 should be kept in the braking state as much as possible for safety reasons, the second transmission member 46 is configured to have a rope-like structure, so that only the force applied by the first transmission member 45 in the pulling direction of the brake holder 41 is transmitted, that is, only in the state requiring unlocking, the brake holder 41 is separated from the ground by pulling close to the second transmission member 46, and in other states, the second transmission member having the rope-like structure will not exert a pressure on the brake holder 41, and thus will not adversely affect the braking performance thereof.

Furthermore, since the second transmission element 46 only needs to provide a pulling force, it can be movably connected to the first transmission element via the linkage structure 47. Specifically, the second transmission element 46 passes through a hole-shaped structure on the linkage structure 47, and a stop end with a radius larger than the radius of the rope-shaped structure and larger than the radius of the hole-shaped structure is arranged at one end of the linkage structure 47, so as to provide a fulcrum for the pulling action of the second transmission element 46. And through the cooperation of the stopping structure 461 and the hole-shaped structure, the second transmission piece 46 and the linkage structure 47 have a replaceable and detachable installation connection relationship, so that the manufacturing cost can be effectively reduced.

the brake assembly 4 further comprises:

and a third connecting member 49 rigidly connected between the brake handle 42 and the flange structure and capable of cooperating with the flange structure to transmit the motion of the brake handle 42 to the motion of rotating the first transmission member.
