Description

Integrated crib guardrail

Technical Field

The utility model relates to a bed protection apparatus field especially relates to an integral type crib guardrail.

Background

The bed guardrail is mainly used for limiting the moving range of the baby on the bed, and is a device for preventing the baby from falling off when rolling over to the edge of the bed. After the bed guardrail is additionally arranged on the traditional bed side, the adult can free hands to handle other housework. Conventional bed fences typically include a frame and a fence cloth wrapped around the frame. The bed guardrail frame generally needs to comprise four rods which are enclosed, an upper connecting rod, a lower connecting rod, a left connecting rod and a right connecting rod.

Baby is at 1 year old, 2 years old, the average height of 3 years old is 75cm respectively, 85cm, 95cm, consequently often the actual effective height of bed guardrail (the distance of mattress upper surface to guardrail top) often needs about 65 ~ 68cm at least, and the mattress on the market, the simmons thickness span is great, it has 12 ~ 13cm to be thinner, it is also 28 ~ 30cm to be thicker, consequently, the guardrail is when designing in the bed, for the not mattress size of adaptation equidimension, still be provided with the stabilizer blade of adjustable height so that convenient and the mattress adaptation of different thickness is fixed.

Chinese patent CN 201822262132.8 discloses a novel lifting device for a bed guardrail, which comprises a vertical rod and a support leg arranged at the bottom of the vertical rod in a lifting manner, wherein the support leg comprises a connecting part connected with the vertical rod, the vertical rod is a hollow rod and is sleeved outside the connecting part, and an adjusting component is arranged between the vertical rod and the connecting part; the adjusting assembly is in including setting up adjusting collar on the montant installs the regulating part on the adjusting collar, a plurality of adjustment tank have been seted up on the connecting portion, the fixing and the separation of adjusting collar and connecting portion are realized to the regulating part business turn over adjustment tank. Because the adjusting component is arranged at the connecting part of the vertical rod and the support leg, the connection and the separation of the vertical rod and the support leg connecting part are realized by pressing the adjusting component, the adjustable connection between the vertical rod and the support leg is realized, and the device is convenient and labor-saving.

But because the lift of adjusting collar needs manual regulation, need adjust many times in order to adapt to mattress thickness or spring bed thickness in order to install the guardrail on the bed, and because the discontinuous setting of gear, in some times, the bottom rail is not firm with the laminating of bed body upper edge, perhaps the bottom rail easily forms great space with the bed body upper edge, brings the potential safety hazard.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problems in the prior art, the utility model provides an integral type crib guardrail, its reason is as follows:
