Description

A kind of device for being used to raise caravan or recreation vehicle roof

Technical field

This patent is related to caravan and recreation vehicle.

Background technology

Caravan and recreation vehicle (RV) are usually dragged behind automobile.In order to which the transport of caravan and RV and storage is made more to hold Easily and more efficiently, usually towed vehicle is designed to convert between storage configuration and expansion structure.

Particularly, caravan or RV of the design with expansible top is common, so that roof is when in use Rise, and for being reduced when transporting or storing.In general, this, which is related to, resists plate (for example, being made of aluminium or glass fibre) and soft stubbornly Property upper wall portion, such as the upper wall portion made of canvas.

In order to raise and reduce roof, typically by being propped up in the telescopic supporting rod of roof corner roof Support.These supporting rods are usually controlled by cable and pulley gear, and operator can move support using winch as a result, Bar, so as to be moved to roof in required structure.

There are Railway Projects during use for cable and pulley gear.Particularly, bearing in pulley is stuck will make it is entire System is inoperable.Similarly, cable abrasion and fracture can equally prevent caravan or RV from using.

The known problem that this patent raises and reduces system for roof is researched and developed.

Utility model content

The one side of this patent provides a kind of device for being used to raise caravan or recreation vehicle roof, described device Vehicle roof supports bar including supporting roof, each vehicle roof supports bar are connected with pushing member, pushing member and power distributor It is connected so that the force compression pushing member being applied on power distributor, each pushing member, which acts on, to be attached thereto On the vehicle roof supports bar connect, to lift vehicle roof supports bar, so as to raise roof.

Preferably, pushing member is the flexible member being located in rigid guideway.In a preferred embodiment, pushing member is by all Helical spring such as extension spring is formed.

Power distributor includes force guide device, for rotary motion (for example, being driven by crank handle) to be converted to line Property movement.The force guide device includes guide spiro rod, and at least one actuator is located on the guide spiro rod.It is being preferably implemented In example, power distributor includes two actuators being located on guide spiro rod, and actuator is threadedly coupled in mutually opposite directions, So that the rotation of guide spiro rod along the first direction causes actuator to be moved away from each other, the rotation of guide spiro rod in a second direction is drawn Actuator is played to move towards each other.

The second aspect of this patent provides a kind of method for raising caravan or the roof of RV, the method bag Include following steps：

Receive rotation input；

The rotation input is converted into the linear motion of at least one actuator；

The linear motion of actuator is converted into being applied to the compression stress of the first end of pushing member；

The second end of pushing member is supported on vehicle roof supports bar；

The compression stress of pushing member is directed on vehicle roof supports bar, so that roof raises.

Specific embodiment

Figures 1 and 2 show that with chassis 12, the caravan 10 of main body 14 and roof 16.Roof 16 can be in such as Fig. 1 institutes It is moved between the down position shown and raised position as shown in Figure 2.Caravan 10 includes flexible upper wall portion 18, in Fig. 1 Down position compressed and the raised position of Fig. 2 extend.

Roof 16 is supported by four vehicle roof supports bars 20, each vehicle roof supports bar 20 is connected to each angle of roof 16 Portion.Each vehicle roof supports bar 20 can stretch in the support shaft 22 of vertical orientation.

Caravan 10 has the power distributor 30 being located in chassis 12.Power distributor 30 is connected to four guide paths 32.Each guide path 32 has the longitudinal component 34 of the approximate centerline positioned at chassis 12, extends along the end of chassis 12 Lateral part 36 and the vertical component 38 that is aligned with corresponding support shaft 22.These three quadrature components 34,36,38 are curved Bent portions 40 connect, and each bent portion 40 has relatively large radius of curvature, about 110mm.

Power distributor 30 includes drive shaft 50, and drive shaft 50 is arranged along the center line positioning of chassis 12.Driving Axis 50 is supported by bearing 52.Screw thread is equipped in most of length of drive shaft 50, as guide spiro rod.

Two actuators 54 are located in drive shaft 50.Each actuator 54 is threadedly coupled with drive shaft 50, and is set It is moved into when drive shaft 50 is rotated in linear axial.Reverse thread connects actuator 54 relative to each other so that drive shaft 50 rotation along clockwise direction moves away from each other actuator 54, and the rotation of drive shaft 50 in the counterclockwise direction makes cause Dynamic device 54 moves towards each other.

The distance that the side of each comfortable drive shaft 50 of actuator 54 extends far enough is with the longitudinal component with path of navigation 32 34 alignments.

The pushing member of flexible elongate is helical spring 60, in each path of navigation 32.Each helical spring 60 exists Inner end is connected to actuator 54, and vehicle roof supports bar 20 is connected in outer end.In the preferred embodiment of this patent, helical spring 60 be extension spring, has limited compressibility, but under compressive state, can be moved by bent portion 40 Dynamic ability.

When drive shaft 50 is rotated in a clockwise direction, actuator 54 moves apart from each other.This has each spiral bullet Spring 60 shifts the effect in coupled guide path 32 onto.The outer end of helical spring 60 is abutted with vehicle roof supports bar 20.This Kind is set so that helical spring 60 keeps compression, it means that their offers are to the thrust of vehicle roof supports bar 20.Vehicle roof supports bar Therefore 20 are pushed upwardly, raise roof 16.Show power distributor 30 in down position and rise position in figs. 6 and 7 Movement between putting.

Drive shaft 50 is connected to the crank handle 62 positioned at the rear of caravan 10.

It should be appreciated that the movement of helical spring 60 is consistent.It, then can be if component deflection, and 16 out-of-flatness of roof Adjustable attachment device 64 is set between each vehicle roof supports bar 20 and roof 16, to be corrected and calibrate.

In use, the rotation of crank handle 62 along clockwise direction causes the rotation of drive shaft 50 so that actuator 54 It moves axially away from each other.This, which has, promotes helical spring 60 by their own path of navigation 32 and applies thrust To the effect of the bottom of vehicle roof supports bar 20.Therefore, vehicle roof supports bar 20 is raised, and roof 16 is promoted its raised position simultaneously Exposure flexibility upper wall portion 18.When roof is in its raised position, crank handle 62 can be fixed, and helical spring keeps pressure Contracting.Or, it can be envisaged that ground provides pin system so that roof 16 is fixed on its raised position, without on helical spring 60 Generate lasting stress.

When roof will decline, crank handle 62 can be rotated in the counterclockwise direction, so as to invert elevation process.Gravity Effect will be enough to reduce roof 16 in the case of the power by helical spring 60 not applied.It is contemplated that roof can also lead to It crosses other manner and its reduction position is for example fixed on by clip.

The obvious modifications and variations of those skilled in the art are considered in the range of this patent.
