Abstract
The utility model relates to a combined curtain for projection, which comprises a fixed frame positioned on the circumference and a projection plane used for screening, wherein the projection plane is installed on the fixed frame and is formed by that a plurality of elongated strip shape projection plane units arrayed successively and tightly are spliced; the end parts of the projection plans are separately connected with the fixed frame. The projection plane unit also comprises a resetting part which is helpful for the curtain to rapidly squeeze out a crack through which the object can pass when the block-shaped hard object impacts the projection plane, and after passing, the resetting part can make the projection plane unit recover the plane state. The combined curtain for projection provided by the utility model utilizes a great number of projection plane units having recoil elasticity to form the curtain face by the continuous plane array. On the occasion of impacting and extruding, the projection plane units can make a crack for the object to pass through; after passing, the projection plane units can also recover the original position by the recovery force to form the normal plane shape curtain face continuously used for projection. The curtain can reduce the impact sound and can not be damaged when the object is impacted at high speed.
Description
Technical field
The utility model relates to the employed screen of a kind of projector equipment, relates in particular to a kind of employed combined type curtain of projector equipment that can be used for the emulation recreation.
Background technology
At present, but the simulation games facility or the simulation demo system of simulated scenario have generally included: lantern projecting equipment, projection screen, electric-control system and emitter, bullet or the ball stage property that to wherein be played or demonstrate by trigger mechanism or operator hit to projection screen, projection screen can show the picture of corresponding scene, electric-control system calculates the expectation track of ball or bullet, and show by projection screen, make ludic activity reach effect true to nature.In the prior art, projection screen is the solid integral curtain cloth of one side, when ball or bullet hits cord, to the intense impact of curtain face, causes the damage of stage property and curtain easily, reduces its serviceable life, also can send bigger bump sound simultaneously, disturbs presentation process; If rebound behind ball or the bullet hits cord, because speed is exceedingly fast, momentum is big, easily injures the personnel on the field.Such as the field of playing ball of some the golf lab simulations on the present market, this type systematic plays out outdoor scene on the curtain face of indoor integral body by magic lantern, the player swings facing to the court of showing out golf is beaten to curtain, ball flies to virtual court, a distant place at a high speed and is actually and impinges upon on the in-plant curtain face, send dull strike note, also can rebound sometimes.This curtain very easily damages, need frequent the replacing, and ball falls and also is not easy in time reclaim ball with attractive in appearance inadequately in face of the curtain, particularly to when the needs that are in the state of practising a ball game hit golf in a large number, the golf of heaping below the curtain face is with the outdoor simulated effect of crash simulation.
Summary of the invention
In order to overcome the deficiency of existing projection screen device, the purpose of this utility model is: a kind of projection combined type curtain is provided, not only can clearly demonstrate the scene picture, and when the rigid object of bulk impacts curtain, curtain can squeeze rapidly to be abdicated the crack and allows object pass and can in time recover flat state after it passes through, this kind curtain is not fragile, and is easy to use, and makes ludic activity reach effect more true to nature.
The purpose of this utility model is achieved in that
A kind of projection combined type curtain, described curtain includes:
One be positioned at the periphery fixed frame and
One can be used for the projection plane of projection;
Described projection plane is installed on the fixed frame, and described projection plane is spliced by the unit, projecting plane of many continuous compact arranged elongated strip shaped; The two ends of unit, described projecting plane are connected with fixed frame respectively, unit, described projecting plane also includes: when the rigid object of bulk impacts projection plane, curtain squeeze rapidly abdicate the crack allow object pass and its by after can be able to make the unit, projecting plane recover the reset components of flat state.
The beneficial effects of the utility model are, a kind of projection combined type curtain is provided, utilize and have unit, the flexible projecting plane of a return continuous level arrangement formation curtain face in a large number, under impact extruded, the crack can be abdicated so that object passes in the unit, projecting plane, object passes unit, projecting plane under return force function, back and can set back rapidly again and put, and forms a normal plane curtain face and continues on for projection.This curtain will pass curtain rapidly with the grating that lowers, thereby simulated effect is more true to nature under the objects at high speed bump, can cause curtain to damage hardly.Noise is little, not resilience of object, the easier and supporting use of recovery system.
