Description
A COLLAPSIBLE BARRIER
Field of the Invention
The present invention relates to barriers and in particular barriers that are coUapsible.
Background of the Invention
The use of barriers is widespread One of the most common uses of barriers is to increase safety of potentially dangerous environments, such as elevated platforms from which someone might fall.
One example of a common form of barrier is a stair balustrade These barriers ensure that someone who is using the stairs cannot fall off the: side of the stairs.
In some locations, a barrier is not necessary 100% ofthe time and in fact can become an obstacle In such circumstances a temporary barrier is more appropriate. One solution is to make the barrier portable. Although portable barriers solve the above problem, they can be difficult to store when they are not in use.
Statement of the Invention
The current invention provides a collapsible barrier comprising: a channel member having a base portion with side walls, said channel member being securable to a surface; a plurality of support members, wherein at least one of the support members is pivotably mounted within the channel member, and at least another of the support members is detachably mounted within the channel member, a hand rail pivotably connected to each of the support members and mounted in parallel with the channel member, a first portion of the hand rail being connected to said at least one detachably-mounted support member, and being detachable from a second portion of the hand rail, which is connected to the at least one pivotably-mounted support rneniber; whereby, upon detachment of the detachable hand rail portion and said at least one detachably-mounted support member, the at least one pivotably-
I
mounted support member and the second portion of the hand rail are displaceable from a first position, where said at least one support member extends perpendicular to the channel member, to a second position, where said at least one support member lies substantially parallel to the second portion of the hand rail and is received within the channel member.
Once the collapsible barrier of the present invention is secured to a surface, the barrier is placed in the first position when the barrier function is required.
However when the barrier is no longer required the detachable elements of the barrier can be removed, this allows the rest of the barrier to be moved to the second position wherein the barrier is reduced to the size of channel member. In this way the barrier of the present invention provides a convenient and quickly erectable barrier that is easier to store.
Preferably the hand rail may be connected to each of the support members by a connecting means. Further preferably each connecting means may be constructed and arranged to enable said support members to lie substantially parallel to the channel member in said second position.
In a preferred embodiment the connecting means may comprise a member which extends from the support member and is pivotably connected to the hand rail, such member including a curved portion.
Preferably the spacing and dimensions of the support members are such that said support members can be fully received within the channel member.
Further preferably the spacing of the support members may be equal to or greater than the height of the barrier. Such arrangements provide an even more compact collapsed state for the barrier of the present invention.
The size of the collapsed barrier may be made even more compact by providing that the second portion of said hand rail may also be received within the channel in said second position.
Preferably the pivoting range of at least one pivotably-mounted support member between the first position and the second position is restricted to an angle of 9Q°. In this way the barrier is only collapsible in one direction, which makes it easier for a single person to erect the barrier.
Preferably at least one of said at least one pivotable support members may be lockable in said first position. The provision of some sort of locking means also makes it easier for a single person to erect the barrier.
Preferably adjacent support members may be connected by at least one additional barrier element. Such additional barrier element may be selected from a group containing: a sheet, a net or mesh, a cable or chain. It is appreciated that the safety of the barrier can be further improved by providing one or more additional barrier elements.
Preferably, to further improve ease of storage, the first portion of the hand rail is detachably connected to said at least one detachably-mounted support member.
The collapsible barrier of the present invention is considered to be of particular effectiveness on long boats, barges and other canal vehicles.
In addition to the above collapsible barrier that present invention provides method for collapsing and erecting said collapsible barrier.
Brief Description of the Drawings
A prefe.rred embodiment of the present invention will be described with reference to the figures, wherein: Figure 1 shows a section of a preferred embodiment of the collapsible barrier of the present invention; Figures 2a, 2b and 2c show three stages in the collapse of the preferred embodiment shown in figure 1; Figure 3 shows the connecting means of the present invention in more detail.
Detailed Description of the Preferred Embodiment
A preferred embodiment of the collapsible barrier of the present invention is shown in Figure 1. Figure 1 shows a straight section of collapsible barrier.
However it is appreciated that the barrier could also be used to form closed off areas, which are rectangular or square in shape.
The collapsible barrier I of the present invention comprises a base member 2, which is preferably a channel member, which is securable to a surface by standard means such as bolts or rivets for example. The channel member 2 can be made from stainless steel or other suitable alternatives thereof. Within the channel member are mounted two types of support member 3, 4. Both types of support member can be made from stainless steel or other suitable alternatives thereof.
The first type of support member is the pivotably-mounted support member 3 and, depending upon the length and shape of the barrier 1, such is usually the most common type used. Each pivotablymounted support member 3 is pivotably mounted within the channel member 2 by way of a pivot joint 3a (see Fig. 2b). Advantageously, in arrangements where a barrier has more than one pivotably-mounted support member, at least one of the pivotably-mounted support members 3 is lockable at an angle of OOC to the channel member 2. Suitable locking means will be appreciated by the skilled person.
The second type of support member is the detachably-mounted support member 4, such are mainly used at one end of a straight run. Each support member 4 is detachably connected to the channel member 2 by way of an interaction between a tension button on the support member 4 and a tension button locator hole in the channel member 2. The interaction between the button and the hole maintains the support member in position until the button is pushed in, at which point the support member 4 can be detached from the channel member 2.
Both the pivotably-mounted support member 3 and the detachably-mounted support member 4 are connected to a hand rail 5 by way of a connecting means 7, said connecting means 7 being pivotably attached to the hand rail 5 by a pivot joint 8. The connecting means 7, which is shown in more detail in Figure 3, will be discussed further below.
The hand rail 5 can be made from stainless steel or other suitable alternatives thereof. The hand rail can be made from multiple parts dependant on the materials available and the total length of the barrier. However it is considered essential that the hand rail comprises at least two portions. The first hand rail portion 5a and the second hand rail portion Sb are also attached to one another using a tension button and a tension button locator hole. Appropriate alternatives to such locking means will be appreciated and include quick release cam locks.
The first portion 5a is attached to the detachably-mounted support member 4 via the connecting means 7. The second portion Sb is pivotably attached to the one or more pivotably-mounted support members 3 via the connecting means 7.
In the embodiment shown in the figures the first portion of the hand rail 5a is pivotably attached to the detachably-mounted support member 4, however it is appreciated that this is not necessary. In addItion, the first portion of the hand rail 5a may be detachable from the detachably-mounted support member 4.
The general mechanism of the collapsible barrier 1 of the present invention will be appreciated from Figures 2a, 2b and 2c. Figure 2a shows a section of erected barrier. Figure 2b shows the partially collapsed barrier I without the detachable portion of the hand rail 5a and the detachably-mounted support member 4. Figure 2c shows the barrier of the present invention in its collapsed state.
Although not shown in the figures it is appreciated that the removed first portion of the hand rail 5a can be attached to the opposite end of the second portion of the hand rail Sb, this makes up the difference in length lost, due to the length gained on its arc of collapse. This further minimises the storage requirements, whilst at the same time providing a continuous run of hand rail along the length of the channel member in both the collapsed and erected state. The detached support members may be stored within the channel or alternatively in an alternative storage means.
The collapsible barrier of the present invention can be used to form a square or rectangular area. A rectangular area can be formed by connecting short runs of the collapsible barrier to the longer runs of hand rail at 90 degrees.
One example where a rectangular area may require a barrier according to the present invention is on canal boats.
A preferred application of the collapsible barrier of the present invention is on the roof of a canal boat. By providing the barrier on the roof of the canal boat, it is possible to create a safe patio' area on the roof Because the barrier is collapsible it can be collapsed into the channel member when it is not needed, thus avoiding problems with low bridges and the like.
It is appreciated that the shape of the area on a boat roof is such that it may not be possible to have full lengths of barrier on the shorter sides of the rectangular area. One appreciated arrangement suitable for such locations involves linking the ends of the two long barriers, which run down the length of the canal boafs roof, with detachable hand rails which can be attached between the ends of the barrier hand rails.
Figure 3 shows the connecting means 7, which enables the support members to lie substantially within the channel member 2 when the barrier I in the collapsed state, The connecting means 7 is attached to the top of the support member 3, 4 by an appropnate fixing (such as a grub screw). The connecting means 7 is attached to the hand rail 5 via a pivotable elbow joint 8, which enables the support member to pivot relative to the hand rail.
The connecting means 7 has a curved portion 7a which provides clearance so that the support member is free to pivot to a horizontal position (see Fig. 2c) whereby the support member is received within the channel member 2.
The safety of the collapsible barrier 1 of the present invention may be further improved by attaching additional barrier elements (not shown) between adjacent support members 3,4.
One form of barrier element are horizontal cables which can for example by set at intervals of approximately 100mm apart rising from the base of the support members 3,4 to the hand rail 5. These barrier elements are fixed at one end of the barrier I to the end support member 3, 4 with cable compression connectors. These are fixed to eyelets that are screwed into the end support member 3, 4.
The cables are fed through the intermediate support members 3, via drilled holes, and connected to the opposite end support member with cable compression joints. These are connected to tension springs at one end, which in turn are connected to eyelets that are screwed to the removable end support member. These can be disconnected from the eyelets allowing the end support member 4 to be removed prior to the hand rail 5 being collapsed into the channel member 2.
By way of further explanation, the process of collapsing the preferred embodiment of the collapsible barrier of the present invention is herein described.
To collapse the hand rail you must first remove the intermediate horizontal cables by releasing the cam locks. The cam locks release the cables from their connecting pins. The connecting pins are located on the detachable support member 4.
Prior to removing the detachable support member the detachable first portion of the hand rail 5a must be removed. To remove the detachable first portion of the hand rail 5a first depress the release buttons on either end of the removable rail. The release buttons are located at each end of the removable hand rail on the underside of the hand rail. To release the ends of the removable hand rail depress the button with thumb or forefinger and pull apart.
To release the detachable end support member 4, release the cam locks these are removable. The cam locks are located to the underside of the detachable first portion of the hand rail 5a, such being located at the top of the end support member. This allows the cam locks to be removed in turn allowing the hand rail to be removed.
The cam locks are attached to the removable first portion of the hand rail by a cable to eliminate the possibility of the cam locks being misplaced or lost during hand rail disassembly.
To remove the end support member 4 depress the two locator buttons either side with thumb and forefinger, these are located at the base of the end support member being both sides of the support member facing inwards and outwards this releases the support member 4 from the channel member 2.
To collapse the second portion of the hand rail 5b depress the locator buttons at the opposing end of the hand rail these are located at the base of the end support member 3. The locator buttons are located on both sides of the support member and face inwards and outwards. This releases the end support member 3 from the locked position and allows the hand rail 5b to drop down into channel member 2.
Secondary locator holes may be located within the channel facing inward and outward allowing the buttons to click in, locking the hand rail 5b down in its closed position.
The detachable hand rail once it has been removed allows the main hand rail to be collapsed to its closed position to the end of the enclosure channel. This eliminates any hand rail overlap. The section of hand rail that has been removed is then connected to its opposite end. This then completes the run of hand rail bring it equal in length to the enclosure channel.
To erect the hand rail the reverse procedure is followed.
