Description

Bed guardrail and mosaic structure

Technical Field

The invention relates to the technical field of bed guardrails, in particular to a bed guardrail and a splicing structure.

Background

Because the existing bed is generally formed by directly placing a mattress on a bed frame, the children are very likely to turn over and drop the bed carelessly during rest, so that the bed guard rail is increasingly applied in daily life and becomes a necessity in the growth process of the infants.

Bed guardrail products have undergone four generations of development, and the technological development process is approximately as follows:

the 1 st generation bed guard rail is almost the same-fixed bed guard rail, soft substance protection baffle plates are assembled in the metal or plastic frame, the lower part of the bed guard rail is provided with a supporting rod which is penetrated into the bottom of the mattress and fixed on the bed board, or the supporting rod is fixed on the bed edge through the assembly part, so that the bed guard rail is fixed on the outer side of the mattress to play a role in safety protection;

the 1 st generation bed guardrail has the following defects:

1: almost can only be used in a single piece, and has small protection area;

2: the bed at one side provided with the bed guard rail is limited with use functions, and can not be normally used for getting on or off the bed;

3: the installation is troublesome, and tools and the like are needed;

4: the long accumulation phenomenon of the protective baffle can occur along with the increase of the service time, and the danger of choking of infants is reserved.

The bed guard rail of the 2 nd generation is a turnover unlocking type bed guard rail, and compared with the product of the 1 st generation, the bed guard rail is provided with unlocking devices at two sides of the guard rail, so that the protective baffle sheet can be turned down, the protective function is relieved, and the bed provided with the bed guard rail can be normally put on and taken off;

the 2 nd generation bed guardrail has the following defects:

1: smaller in size, with a length of 120CM or less;

2: the depth of the embedded bed edge is not enough and is within 10CM, and the part is even only 2-5CM;

3: the height is very low, as long as the child cannot fall off the bed when sleeping;

4: the bed guard rail can be turned down only by unlocking at two sides;

5: the product of the 1 st generation is almost used as a single piece, and the protection area is small;

6: the long accumulation phenomenon of the protective baffle can occur along with the increase of the service time, and the danger of choking of infants is reserved.

The 3 rd generation bed guard rail is still a turnover unlocking type bed guard rail, the technical characteristics of the 2 nd generation bed guard rail are improved according to the domestic market, the size of the bed guard rail is increased, the embedding depth is increased, the bed guard rail is heightened and the like;

the shortcomings of the 3 rd generation bed guard rail are:

1, a step of; the bed guard rail has great problem in shaking property when the bed guard rail is directly pulled to be large in size;

2: the bed guard rail can be turned down only by unlocking at two sides;

3: the multi-piece splicing can be realized, the protection area is increased, but when the cross installation (the bed side and the bed tail are all installed) is adopted during the splicing, a large gap of 5CM to 10CM can be formed, meanwhile, the cross part is raised due to the fact that the support rods inserted below the mattress are crossed, one bed guardrail on one side of the adjacent bed guardrails is unstable, and the installation is troublesome due to the fact that tools are needed during the splicing;

4: the long accumulation phenomenon of the protective baffle can occur along with the increase of the service time, and the danger of choking of infants is reserved.

The 4 th generation bed guardrail is an up-and-down lifting unlocking type bed guardrail, soft substance protection baffle plates are assembled in a metal or plastic frame, upright posts are arranged on two sides of the protection baffle plates, and an unlocking device is arranged on each upright post on two sides of the protection baffle plates, so that the up-and-down lifting of the bed guardrail protection baffle plates can be controlled, and the lower cross rod of the bed guardrail can adapt to the thickness of different mattresses;

the disadvantage of the 4 th generation bed guard rail is:

1: very shaking;

2: the cost is high;

3: when the bed guard rail is lifted, the bed guard rail needs to be kept in a horizontal state or a state close to the horizontal state;

4: lifting of the bed guard rail can be completed only by unlocking on two sides;

5: the problem of cross installation of the support rods during splicing is still not solved, and the splicing needs tools, so that the installation is troublesome;

6, preparing a base material; the long accumulation phenomenon of the protective baffle can occur along with the increase of the service time, and the danger of choking of infants is reserved.

7, when adjacent two-sided bed guardrails are spliced, tools are needed to be used, the installation is troublesome, and hidden dangers of scratch users are reserved on the surface of the exposed hardware assembly part;

8, when the adjacent two-sided bed guardrails are spliced, the connecting piece at the spliced position is higher than other parts of the bed guardrails, and a rope or a strip-shaped object with the rope is reserved for the danger of the infants and young children.

The bed guardrail splicing structure on the prior market mainly comprises three types:

the utility model provides a splice structure is single turn over and turns over and lock bed guardrail or uses cross-mounting when rising degradation lock bed guardrail concatenation, accomplishes the concatenation through the intercrossing of bracing piece is fixed, and the problem that this kind of concatenation mode brought is many, mainly has:

1: wen Cha location bump;

2: the guardrail of one side bed is unstable;

3: a large gap of 5-10CM and a loose bolt can be formed at the splicing position;

4: the splicing needs tools, and the installation is troublesome.

The utility model provides a mosaic structure is for designing fixed two-sided dress bed guardrail, two-sided bed guardrail is 90 degrees contained angles promptly, wears the bracing piece of two-sided bed guardrail, fixes with the screw, solves the gap problem of cross mounting, but the problem that brings is:

1: sales are very cumbersome and the user needs to determine whether to install on the left or right;

2: the crossing part of the support rods bulges;

3: the installation is troublesome and a tool is needed;

4: the splice of the guardrails is provided with a larger or smaller gap, and the larger the splice is, the safer the splice is, and the like.

The utility model provides a mosaic structure is for connecting the bed guardrail that two sides are adjacent through at least one connecting piece and fix, and the design that the bracing piece flattened appears to satisfy the demand of customer multi-disc bed guardrail concatenation installation, this kind of concatenation mode has had great progress for above-mentioned two kinds of mosaic structure, still has following problem:

1: the support rods are flatly designed to try to solve the problem of interference of the support rods at the adjacent parts of the two-sided bed guardrails, but the support rods are actually pseudo-required and face the problem of insufficient strength;

2: the splice is not firm and can displace;

3: gaps are reserved at the joints of the bed guardrails, and the gaps become larger along with the increase of the service time, so that the bed guardrails are unsafe;

4: when adjacent two-sided bed guardrails are spliced, the two-sided bed guardrails are locked and fixed by using a screw rod by means of a tool, the exposed hardware has potential safety hazards, the screw rod can be loosened along with the increase of the service time, and the splicing operation is troublesome;

5: when adjacent two-sided bed guardrails are spliced, the connecting piece at the spliced position is higher than other parts of the bed guardrails, and ropes or other strip-shaped objects are reserved for the danger of the infants and the young children.

To sum up, up to now, no product can meet the needs of 1, 2, 3 and 4 bed guardrails of customers, and various forms are subdivided products, and even if the products can be spliced, a plurality of problems exist, such as the fact that the products cannot be well attached to the corners of a mattress, are unstable, and have gaps and the like.
