Abstract
The utility model discloses a ladder for going up or down stairs of lofts, which comprises a cover board for a loft opening and the cover board is hinged on the rim of the loft opening and can be rotated downwards. Furthermore, a locking mechanism is arranged between the cover board and the loft, a ladder is fixed on the cover board and the ladder can adopt a telescopic structure and can also adopt a folding type structure. Additionally, the peripheral dimension of the ladder is less than the cover board after retraction, the length of the ladder is longer than the height of the loft and an angle which is suitable for climb is formed after the ladder is overlapped on a floor. The utility model has the characteristics of reasonable structure, safety, time saving, labor saving, reduced construction, reduced operating cost, etc., besides, the utility model does not occupy the limited space of rooms.
Description
Technical field:
The utility model relates to a kind of civilian construction facility, particularly relates to a kind of ladder of loft up and down that is used for.
Background technology:
At present, the real estate commercial city in a lot of cities has been released and has been bought the channel of sales that attic send loft, and has most of loft not have stair activity, only to loft leave 400 * 400mm confess into the passway.In the river, ground such as Zhejiang, Fujian, Jiangxi, suburb of Shanghai all is that two and half, three and half, four and half (half storey wherein is a loft more than 90%, loft lowest part 1.5), the attic in the city is mainly placed the foreign material that seldom use in some lives or bigger place uses it for anything else in the space.In south, most of loft all is used to store grain and some food that can place for a long time, and fixing stair not all, its objective is protection against rodents, and loft all is to adopt the method for removing ladder up and down.Building band loft in the city and not establish the stair reason a lot of says that to the developer construction cost is low, sells than being easier to.To the house purchaser, can spend less, live in bigger space house.The person of having ready conditions is provided with fixed stair in the limited interior space.Like that destroyed the integral layout in the room again, and take indoor 3～4 square metres area, strengthened the cost of moving in, returned finishing, layout, daily life and bring inconvenience.If use portable ladder, the time spent holds up and, and the time spent does not move again, shifts from one place to another to take a lot of work, require great effort and dangerous, and 3 meters long ladders are moved also inconveniently indoor in addition, and placing also is a problem.The loft of therefore a lot of resident families is all on the shelf, and therefore, loft has become resident's a worry up and down.
Summary of the invention:
Technical problem to be solved in the utility model provides a kind of ladder of loft up and down that is used for, this ladder structure novelty, at any time folding and unfolding, neither take the interior space, being convenient to interior decoration arranges, also can reduce the cost of use of ladder, the room is whole unaffected simultaneously, can solve the worry of removing ladder back and forth, safety again, convenient, attractive in appearance, practical, technical solution adopted in the utility model is as follows, this novel loft velar plate that comprises, cover plate is hinged on the edge of loft mouth, and can rotate, between cover plate and loft, be provided with locking mechanism, it is characterized in that the cover plate upper fixed has ladder, this ladder adopts stretching structure, and the peripheral size after ladder is packed up is less than cover plate, length after opening is greater than the height of loft, and ladder is overlapped on formation scansorial angle in back on the floor.
The ladder of above-mentioned stretching structure can be interior stretching structure, also can be outer stretching structure.
Above-mentioned ladder can also adopt collapsible, and the peripheral size after folding is less than cover plate, and the length after opening is greater than the height of loft, and ladder is overlapped on formation scansorial angle in back on the floor.
The ladder and the collapsible ladder minor structure of interior stretching structure and outer stretching structure all are prior arts, as long as the length after designing overall dimensions and opening.
The utility model can adopt manual control, also can adopt hydraulic control.
Mechanism of the present utility model is as follows: when adopting manually control, at first open locking mechanism by key, rotate cover plate, then ladder is opened and is overlapped on the floor and can use; When adopting hydraulic control, executing agency can adopt liquid bidirectional spring or door closer, power-assisted buffer spring and hang parts such as hinge, during use, by private key the lock on the cover plate is opened, slightly pull down, under the effect of liquid bidirectional spring and own wt, ladder slowly puts down when arriving the dead point of hanging hinge and stops, in that collapsible or telescopic section ladder are opened, can use.Earlier collapsible or telescopic section are recovered to the home position during withdrawal, the power of slightly a bit making progress for ladder is taken in loft with ladder under the effect of liquid bidirectional spring and power-assisted buffer spring again, and the ladder locking is got final product.
Compared with prior art, the utlity model has rational in infrastructure, safe and reliable, time saving and energy saving, do not take indoor limited space, reduce characteristics such as construction and cost of use.

Accompanying drawing 2 is the utility model embodiment two structural representations.
Accompanying drawing 3 is the utility model embodiment three structural representations.
Specific embodiments:
Embodiment one:
As shown in Figure 1, the utility model comprises loft velar plate 1, cover plate is hinged on the edge of loft mouth, and can rotate, between cover plate and loft, be provided with locking mechanism, it is characterized in that the cover plate upper fixed has ladder 2, this ladder adopts telescopic structure, peripheral size after ladder is packed up is less than cover plate, and the length after opening is greater than the height of loft, and ladder is overlapped on formation scansorial angle in back on the floor.
Embodiment two: the utility model comprises loft velar plate 3, cover plate is hinged on the edge of loft mouth, and can rotate, between cover plate and loft, be provided with locking mechanism, it is characterized in that the cover plate upper fixed has ladder 4, this ladder adopts accordion structure, and the peripheral size after ladder is packed up is less than cover plate, length after opening is greater than the height of loft, and ladder is overlapped on formation scansorial angle in back on the floor.
Embodiment three: accompanying drawing 3 is these novel foldable integral formula schematic diagrames, it is installed in the reserved opening that does not have stair or newly opens or enlarge on the passway, use the framework 5 of plank and steel plate making all around, framework is provided with guardrail 6, the power-assisted buffer casting, hang hinge band 7 and liquid bidirectional spring or door closer 8 and hinged joint, the ladder body is fixed on the removable cover 9, and be connected with hinged joint, liquid bidirectional spring or door closer 8, the power-assisted buffer casting is connected with removable cover 9, during use, open the lock on the removable cover 9, open ladder second again after the ladder body exposes, three joints can use.
The utility model can also change automated fluid bidirectional spring formula door closer into the electronic pull bar form of (comprising hydraulic cylinder, cylinder).
