Description

[Detailed description of the invention] passage device The invention relates to passageways of the type described in the introductory part of the following claims. b) Concerning equipment.

It is generally removed and stored when not in use, and can be easily brought back into use when it is time to use it. There is a need for such an easily transportable passageway. The purpose of these passages is For example, between two building structures on land, between two rig structures at sea, or between stationary rig structures at sea. It is used between stationary and movable structures, such as between trucks and ships.

Known passage devices can be moved from a non-use position to a use position and vice versa by a crane or the like. The bottom is made as a one-piece rigid structure that can be rotated. These known passage devices generally have the disadvantage of occupying a large amount of space when stored when not in use. .

The purpose of the present invention is to greatly reduce the occupied space when not in use, and to easily bring it back into use. By means of a passageway device that can be used for The purpose is to solve the above drawbacks.

The device of the present invention is characterized by the features shown in the characterizing part of claim 1 below. being commanded.

A passageway section according to the invention suspended via support means on a common support means. Depending on the party using the product, it is possible to change the state of non-use to the state of use in a relatively easy way. Or vice versa, put cefushiran in each passage and push it into each other to make it unusable. It is now possible to return it to its original position. The said passage section of the present invention comprises strut means and A relatively simple method that allows ready-to-use passages to be formed in support means of can be adjusted to the correct use position along the fixed passage structure separately. .

Further features of the invention will become apparent from the following description with reference to the accompanying drawings. cormorant.

FIG. 1 is an end view of the device of the present invention.

FIG. 2 is a side view of the device of the present invention.

FIG. 3 is a plan view of the device of the present invention.

FIG. 4 is a perspective view of the device of the invention shown in the non-use position.

FIG. 5 is a detailed view showing a part of the device according to the invention in vertical cross section, and FIG. It stretches over the surface. Rails for each paired section 26.27tE each section are mounted so that they are always engaged with each other during relative displacement. Furthermore, on The side sections are supported by support wheels 28 onto the lower sexu The support wheels 28 roll directly on the upper side of the lower section. moreover , each section is provided with a longitudinally reinforcing beam 29 having a C-shaped cross section. There is an inward opening within the section. The upper section is above beam 29 A support engagement body is formed by another support wheel 30 that comes into contact with the side flange 29a. Ru.

At the tip of each section 238-23d are each two parallel strut means 11.12. A wire member fixed to a sliding body 32 mounted so as to be easily displaced over the A pair of support members 31 in the shape of are provided. This wire member 31 is compatible As shown in Figure 1, it expands upwards from the section 9 towards the support means. . By means of these series of paired wires 31 and corresponding support means 11, 12, and... The passageway structure is stably fixed in a central position relative to the central support means 10.

The sliding means/locking means 13 and the members 14 and 15 shown in detail in FIGS. will be accomplished. One end of an adjustment screw 36 is connected to the center of the clamping arm 14 in a flexible state. It is. The corresponding center portion of the clamping arm 15 is rotatable around the pivot pin 37. supports a nut 38 attached to the screw 36 which extends axially along the thread 36 It is freely adjustable. The screw 36 is provided with a socket portion 39, and this socket The cut portion 39 is a separate drive member for relatively adjusting the clamping arms 14 and 15. Accept 16. Support wheels 414 supported at the upper ends of the clamping arms 14 and 15 It is supported on the lower horizontal flange 10a of the strut means 10.

The sliding and locking means 13 are controlled by the clamping plates 42, 43 at the upper end of each support arm. A lock thereon at any location along the strut means via the vertical central web 10b of the beam. It can be fixed and clamped in a fixed position.
