The folding and unfolding ladder has a reasonable design, a simple structure and high safety, is convenient to unfold and fold and comfortable to climb and is applicable to various double-layer beds and similar products.

Description

Bunk beds are with the ladder of taking down the exhibits

Technical field

The utility model relates to double-deck bed steps, is a kind of bunk beds with the ladder of taking down the exhibits.

Background technology

Bunk beds are meant the combined metal bed that is provided with upper and lower two-layer bed, and it generally is made up of bedstead, roof beam structure, bed board, bed steps, and bedstead is connected with roof beam structure, are provided with bed board between two roof beams structure, and bed steps are convenient for people to from the lower berth climbing to the upper berth; For the safety on upper berth, the upper berth generally also is provided with safety barrier.Bunk beds are better for the space availability ratio in room, are widely used in the dormitories such as school, factory.As the ZL patent No. 02214991.0 that discloses in the Chinese patent literature, May 7 2003 Granted publication day, utility model title " a kind of ladder that is used for bunk beds ", this ladder comprises two terraced bars and some steps, respectively there is a through hole at the two ends of each step, two through holes axially identical, the axis of through hole and the axes intersect of step and vertical, the shape of through hole is identical with the shape of terraced bar cross section, the size of through hole is slightly larger than the size of terraced bar cross section, and terraced bar is set in the through hole of step and with step and is fixed together.But ladder that above-mentioned bunk beds are used and existing bed steps are comparatively close, and by the cross bar climbing of bed steps, because foot's lifting surface area is less, sole is pain comparatively during climbing.

Summary of the invention

For overcoming above-mentioned deficiency, the purpose of this utility model is a kind of expansion to be provided, to draw easily bunk beds in the ladder of taking down the exhibits to this area, makes it solve the comparatively inconvenience of taking down the exhibits of existing like product, and sole is stressed uncomfortable during climbing, the technical problem that structure is comparatively single.Its objective is and be achieved through the following technical solutions.

A kind of bunk beds comprise main ladder of bed and the secondary ladder of bed with the ladder of taking down the exhibits, this ladder, and the main ladder of bed is arranged at a side of bedstead, and bedstead is connected with roof beam structure, and the upper beam of roof beam structure has set up guardrail, is provided with bed board between two roof beams structure of bedstead; Guardrail is for ensureing the safe in utilization of upper berth, and the main ladder of bed that main ladder of bed and the secondary ladder of bed are formed is convenient for people to by the lower berth climbing to the upper berth.It is characterized in that a main ladder of described bed and the secondary ladder of bed are respectively equipped with terraced cross bar, be connected by connector, bolt respectively between the main ladder of bed and the secondary ladder of bed that the distance between a main ladder of bed and the terraced cross bar that pair is terraced is less than 20cm; The top of the secondary ladder of bed is provided with hook, and hook is connected with the last roof beam structure of roof beam structure.The main ladder of bed is fixed in bedstead, launches or gathering by connector and the secondary ladder of bolt band movable bed; The secondary ladder of bed draws in when bed master ladder, makes the secondary ladder of bed be hung on upper roof beam structure by hook; When the secondary ladder of bed launched, the leg of the secondary ladder of bed was fixed in ground.Because the width of 20cm makes when climbing the upper berth less than the length of pin between the terraced cross bar of the terraced cross bar that the bed master is terraced and the secondary ladder of bed, the stress point of sole increases, and is comparatively comfortable when foot climbs, the security when improving climbing.

According to above-mentioned identical principle, be provided with pedal between main ladder of described bed and the secondary ladder of bed, pedal is connected with bed master ladder, the secondary ladder of bed respectively by bolt.When the secondary ladder of bed launches, the footmuff plate development; When the hook of the secondary ladder of bed was hung on roof beam structure, pedal drew in.Pedal increases the lifting surface area of sole, and is further comfortable and safe during climbing.

The utility model is reasonable in design, and is simple in structure, and it is convenient to launch, draw in, climbs comfortablely, and security is good, is applicable to all kinds of bunk beds, ex hoc genus anne product.

The specific embodiment

In conjunction with the accompanying drawings, the utility model is further described.Existing bunk beds generally are made up of bedstead 1, roof beam structure 2, bed board 3, guardrail 4, bed steps, and bedstead is connected with roof beam structure respectively, are provided with bed board between two roof beams structure of symmetry, and last roof beam structure 201 is provided with guardrail.Such as Fig. 1～shown in Figure 3, the utility model increases the secondary ladder 6 of bed at the architecture basics of existing bed, the bed steps of existing bunk beds are as bed master ladder 5, the main ladder of bed and the secondary ladder of bed are respectively equipped with terraced cross bar 602, is connected by connector 7, bolt 8 between the main ladder of bed and the secondary ladder of bed, the terraced top of bed pair is provided with links up with 601.When the secondary ladder of bed uses, launch the secondary ladder of bed by connector, bolt, the distance between main ladder of bed and the secondary ladder of bed is less than 20cm, and the leg of the secondary ladder of bed lands; When climbed on the upper berth, the terraced cross bar of the terraced cross bar of the main ladder of bed and the secondary ladder of bed was as stress point, and sole is comparatively comfortable.After the secondary ladder of bed uses, when not needing the secondary ladder of bed,, the secondary ladder of bed is hung on roof beam structure by the hook of the secondary ladder of bed.

Such as Fig. 4, shown in Figure 5, sole is more comfortable when climbing to the upper berth for making, and the main ladder of bed and the secondary ladder of bed omit a terraced cross bar, interconnect by nut, pedal 603.Like this, the stress point of two terraced cross bars is changed into by pedal as stress surface during climbing, and sole is more comfortable during climbing.
