safety ladder for bed

Abstract

The invention discloses a safety ladder for beds, and belongs to the field of ladder stand for beds. A pair of climbing shoes which is used as an anti-skid device is arranged on a tread crosspiece, and the climbing shoes realize raising or declining function of the climbing shoes along ladder columns by a structure that slide bars move along slide rails; the climbing shoes realize the function that the climbing shoes deflect in a horizontal plane by a structure that telescoping rods are hinged to the slide bars; a heel of the climbing shoe is provided with a torsion spring mechanism 1, when aheel of a user treads, a pressing block is pressed down, an overturning block rotates upwards therewith, and a blocking barrier is formed at an outside of the heel; the bottom of the climbing shoe isprovided with a torsion spring mechanism 2, when the climbing shoes tread on the tread crosspiece, an active bar deflects and drives a passive bar to deflect, and clamping edges are stably clamped atfront and back sides of the tread crosspiece. The product has good antiskid and safety performance, flexible and ingenious structure, and application demands of the ladder for beds are satisfied.

Description

technical field [0001] The invention relates to the field of bed ladders, in particular to a bed safety ladder. Background technique [0002] The bed ladder is a kind of ladder installed on the edge of the bed. It is more common in bed structures in the form of bunk beds, such as beds for campus dormitories, mother-child beds, etc. Its basic structure is generally two ladder columns on both sides of the ladder and a number of equal-spaced stepping rungs between the two ladder columns. When in use, the user holds the ladder column and steps on the stepping rungs , Climb up step by step until you reach the upper bed; when you climb down, you also move down step by step until you step on the ground. In the process of climbing up or down, slippery is likely to occur, causing the user to fall off the ladder and cause physical and mental damage to the user, so it is necessary to pay attention to and increase the safety performance of the bed ladder. [0003] At present, the exis...

Problems solved by technology

In the process of climbing up or down, slippery is likely to occur, causing the user to fall off the ladder and cause physical and mental damage to the user, so it is necessary to pay attention to and increase the safety performance of the bed ladder

[0003] At present, the existing bed ladders generally adopt the method of wrapping anti-slip cushions or other anti-slip devices on the crosspieces of each step to achieve the anti-slip effect. The anti-slip effect is only realized from the material, and the anti-slip effect is poor and the safety performance is insufficient; And the structural flexibility is poor, and the degree of satisfaction for the application requirements of the bed ladder is not high enough
