Abstract

Изобретение позвол ет повысить эффективность и удобство пользовани устройством. Оно содержит стойки 3 дл креплени волейбольной сетки. Верхние части стоек шарнирно св заны с рамами 1. Рамы закреплены на перекрытии помещени . Оси шарниров расположены в плоскости сетки и образуют между собой тупой угол. На рамах смонтированы держатели стоек в нерабочем (верхнем) положении. Дл фиксации стоек в рабочем положении в полу помещени имеютс стаканы. На нижних част х стоек имеетс винтова пара. Винт этой пары входит в стакан и фиксируетс в нем. 2 з.п. ф-лы, 6 ил.The invention improves the efficiency and usability of the device. It contains uprights 3 for attaching a volleyball net. The tops of the pillars are hingedly connected to the frames 1. The frames are fixed on the ceiling of the room. The hinge axes are located in the grid plane and form an obtuse angle between them. The frames are mounted holders racks in non-working (upper) position. There are cups in the floor for fixing the racks in the working position. At the bottom of the pillars there is a screw pair. The screw of this pair enters the glass and is fixed in it. 2 hp f-ly, 6 ill.

Description

кировка приводных барабанов 7 (средст- 25 положении, а верхние части стоек усва блокировки не показаны) и одновременным вращением обоих приводных барабанов 7 на разматывание тросов 6 стойки 3 опускаютс в вертикальное положение , по достижении которого приводные барабаны 7 отключаютс . В св зи с тем, что свободные концы стоек 3 при их опускании расход тс , волейбольна сетка нат гиваетс . Окончательно сетка до первоначального состо ни нат гиваетс при фиксации стоек 3 к полу 17 спортивного сооружени средствами дл фиксации стойки в рабочем положении в пор дке, обратном указанному выше. Одновременное враще-. ние приводных барабанов обеспечиваетс устройством синхронизации.The driving drums 7 are knocked down (the device is in the 25 position, and the upper parts of the racks are not shown) and by simultaneously rotating both the driving drums 7 to unwind the cables 6 the racks 3 lower to the vertical position, after reaching which the driving drums 7 turn off. Due to the fact that the free ends of the uprights 3 are lowered when they are lowered, the volleyball net is tightened. Finally, the grid, up to the initial state, is tightened when the racks 3 are fixed to the floor 17 of the sports structure with means for fixing the rack in the working position in the reverse order indicated above. Simultaneous rotation The drive drums are provided with a synchronization device.

Использование изобретени позвол ет расширить сферу применени устройства дл креплени спортивных снар дов , распростран ее на спортивные сооружени , не имеющие свободного пространства под полом, за счет креплени устройства к строительным конструкци м верхнего перекрыти спортивного сооружени или к специально устроенным несущим конструкци м над игровой площадкой спортивного сооружени , а также значительно повысить удобство в пользовании за счет того, что волейбольна сетка каждый раз не снимаетс (не ставитс ) при смене рабочего и нерабочего положений устройства , а ручные операции при сменеThe use of the invention makes it possible to extend the scope of application of a device for fastening sports equipment, extending it to sports facilities that do not have free space under the floor, by attaching the device to the building structures of the upper ceiling of a sports facility or to specially arranged supporting structures facilities, as well as significantly increase the ease of use due to the fact that the volleyball net is not removed each time (does not put) when changing ochego and the nonworking position of the device, and manual operations when changing

тановлены в рамах на шарнирах, оси поворота которых расположены в плоскости сетки с образованием между собой тупого угла, при.этом приводна трособлочна система состоит из двух идентичных узлов, тросы каждого узла св заны с верхней частью соответствующей стойки и с рамой, а кажда стойка снабжена зацепом дл соединени с ее держателем.The hinged frames in the frames, the pivot axes of which are located in the grid plane with the formation of an obtuse angle between them, with this drive cable-and-block system consisting of two identical nodes, the cables of each node are connected to the upper part of the corresponding rack and frame, and each rack has hook for connection with its holder.

2.Устройство по п. 2, отличающее с тем, что кажда стой ка имеет на нижнем конце винтовую пару , гайка которой закреплена неподвиж но на торце стойки, а инт расположен вдоль оси стойки и имеет торцовую поверхность , коническую и цилиндрическую направл ющие поверхности и упорный буртик дл взаимодействи со стаканом и шарнирно установленные руко тки дл его вращени , при этом в полости стакана расположена подпружинен на пробка дл запирани винта.2. The device according to claim 2, characterized in that each rack has a screw pair at the lower end, the nut of which is fixed at the end of the rack and the int is located along the axis of the rack and has an end surface, a conical and cylindrical guide surfaces and a stop collar for interacting with the glass and pivotally mounted handles for its rotation, while in the cavity of the glass there is a spring-loaded cork for locking the screw.

3.Устройство по п. отличающеес тем, что каждый держатель стойки в нерабочем положении содержит закрепленную на раме плиту, смонтированные на ней электромагнит с корем и штоком и упор с направл ющим ;отверстием дл штока, при этом шток подпружинен к упору, а зацеп стойки выполнен в виде зычка с пазовым отверстием дл штока.3. The device according to claim. Characterized in that each rack holder in the off position contains a plate fixed to the frame, an electromagnet mounted on it with a bark and a rod and an emphasis with a guide; a hole for the rod, while the rod is spring-loaded to the stop, and the hook of the rack made in the form of a tongue with a slot hole for the rod.
