A01g 9/16; E06b 7/14, 3/58 U.S. Cl. 52-66 6 Claims ABSTRACT OF THE DISCLOSURE A greenhouse construction is provided which is attachable to a supporting structure such as a house or the like. The greenhouse construction is portable and readily assembled and to this end is foundationless or substantially so. To facilitate assembly of the construction there is provided a demountable framework which is received by expansion-type receptacles which accommodate deviations from proper alignment and which furthermore accommodate expansion and contraction due to changes in temperature and so forth. A particular design is provided for the framework members such that glass panes can be readily mounted at the place of final assembly.
BACKGROUND This invention relates to greenhouse constructions which are readily assembled from prefabricated parts and which can be mounted to accommodate variances in tolerances and dimensions and the like.
The invention moreover provides for an assembly operation which can be performed in a relatively short period of time thereby rendering the construction of the invention suitable for home use and for purchase and use by-persons who have no special mechanical skills.
Greenhouses are known which consist of a framework in which are mounted glass panes and which provide for an enclosure within which the atmospheric conditions may be controlled. These greenhouses usually consist of a large number of parts which must be precisely brought together and connected and which require a reasonable amount of mechanical ability for purposes of assembly.
Still other greenhouses are known which are relatively small in size and which may be mounted on a standing structure such as by being attached to enclose a window of a dwelling or the like.
It is an object of the invention to provide an improved greenhouse construction which in turn provides for an enclosure of substantially unlimited size and which construction is of a portable nature and can be readily assembled or dismounted.
Another object of the invention is to provide an improved greenhouse construction involving the use of elements wherein glass panes can be readily assembled and mounted at the site of assembly of the greenhouse.
Yet another object of the invention is to provide an improved greenhouse construction which facilitates accommodation of irregularities in the ground on which the greenhouse is to be mounted.
Still another object of the invention is to provide an improved greenhouse construction which automatically provides allowances for angular deviations of the walls to which such greenhouses will be applied.
Yet another object of the invention is to provide an improved framework for a greenhouse of the aforenoted type in which convenient provisions are made for the drainage of condensed moisture.
SUMMARY OF INVENTION To achieve the above and other of the objects of the invention, there is provided a greenhouse construction comprising a framework having at least one open side and an open bottom and expansion means to engage the framework adjacent the open side and bottom to support the framework on the ground and to connect the framework to an adjacent structure.
Said expansion means may include at least one horizontal channel adapted to support the framework at the bottom thereof, the channel opening in upward direction and the framework including at the lower extremity thereof a member which engages in sliding relationship in the channel and being thereby adapted to accommodate displacements between the framework and channel.
In accordance with one feature of the invention, the aforesaid member may be constituted by a foot extending across the internal breadth of the channel, there being means connected to the foot to support a pane of glass and spline means adjacent the pane of glass to hold the same in position relative to said foot.
According to another feature of the invention, the framework may attach a hinged top and a projection extending upwardly therefrom, the expansion means including an expansion strip mountable on the aforesaid adjacent structure to slidably accommodate the above noted projection.
In accordance with the invention, the channel may be supported, for example, on a wood or concrete base, there being moreover provided a concrete anchor sunk into the ground and in which is imbedded a connecting member which is attached to the aforesaid base.
According to a further feature of the invention, the framework may consist of extrusions including the aforesaid foot from which extends a flange to which is attached a T-shaped member extending outwardly from the flange above the foot and defining upper and lower compartments with an angular member being provided which extends from the flange into the upper compartment to subdivide the same into two sections, one of which receives the pane of glass and the other of which receives an elongated plastic spline member which holds the pane against the flange.
In accordance with still further features of the invention, the framework may include a hinged door and a louvre and other such structural members as will ordinarily be found in greenhouse constructions of substantially higher cost.

DETAILED DESCRIPTION A greenhouse construction of the invention is generally indicated at 10 in FIG. 1. In this form it has already been assembled and mounted on a wall 12 of a dwelling (not shown in entirety) adjacent which is a tract of ground 14.
As is well known, the angle between the wall 12 and the ground 14 is preferably a right angle for purposes of construction. However, since the ground is usually graded to provide for drainage, it seldom occurs that the wall 12 and the ground 14 are in perfect perpendicular relationship with one another.
In any event, even should such perpendicular relationship obtain at a given time, this relationship would soon change due to atmospheric conditions involving the presence of moisture and temperature variations and furthermore due to the fact that the ground is not a simple inert mass which retains one surface configuration for an extended period of time.
The invention thus provides a construction which enables those possessing no particular mechanical skills to erect a greenhouse construction serving all of the known functions of greenhouses, while at the same time accommodating the imperfections of environment noted hereinabove.
In general, a greenhouse construction of the invention may consist of sides 16, 18, and 20, all of which are closed by appropriately mounted panes of glass as will be discussed hereinafter. The greenhouse may further consist of a hinged top 22. One side, such as indicated at 24, will be an open side and the bottom 26 of the greenhouse will also preferably be open for purposes of economy and ease in installation. It will be noted that the open side 24 is effectively closed off from ambient weather conditions due to the fact that this side abuts the Wall 12 of the aforesaid dwelling.
The lowermost extremities of the sides 16, 18 and 20 are supported on beams 28. These beams may be readily placed into position as will be indicated in further detail hereinbelow. These beams may be Wood beams made from a material such as redwood or in the alternative may be of a concrete or plastic and the like.
As appears in FIG. 3, there may be sunk into the ground one or more concrete anchors in which are imbedded metal strips or sticks 32 connected by means such as bolts 34 to the side edge of the base on either the inside or the outside of the greenhouse construction.
The hinged top 22 is shown in greater detail in FIG. 2. It consists of a framework 36 on which is mounted a hinge 38 from which extends a projection 40. The projection 40 is accommodated in an expansion member 42 which is generally of Z-shape and which consists of arms 44 and 46 connected by a transverse spacing member 48.
The expansion member 42 is connected by a plurality of bolts 50 or the like to the wall 12 with respect to which it defines a slot 52 in which the projection 40 is slidably accommodated.
The connection and support of the lower extremity of the framework is illustrated in FIG. 3 wherein is seen the above noted base 28.
To the top 54 of the base is connected an expansion member 56 consisting of a U-shaped channel 58 having a flange '60 extending laterally therefrom. The flange 60 is connected to the base 28 by means of bolts 62 or the like with the walls 64 and 66 of the U-shaped channel extending upwardly therefrom. The U-shaped channel has an internal breadth B which determines corresponding dimensions of the framework as will be shown.
A pane 68 of glass or the like which constitutes part of one side of the greenhouse construction is supported in a framework element 70, the details of which will be described. This framework element, it should be noted, comprises a foot 72, the breadth of which corresponds to the breadth B of the U-shaped channel 58 and when the foot is slidably accommodated in said U-shaped channel the U-shaped channel is obturated thereby.
FIG. 4 illustrates the details of the framework element 70 which, as noted above, includes the foot 72. Extending upwardly from the foot 72 is a flange 74 having perpendicular relationship therewith.
A T-shaped element 76 extends outwardly from flange 74 and is positioned above the foot 72. The T-shaped member 76 includes a web 78 and a cross member 80 which defines with the flange 74 two compartments 82 and 84.
An angularly disposed member 86 extends from the intersection of the flange 74 and web 78 int the compartment 84 at substantially a 45 angle. This divides the compartment 84 into two sections, in one of which is accommodated the pane 68 and in the other of which is accommodated an elongated plastic spline element 88.
The flange 74 is provided at its upper extremity with a roughened surface constituted for example by a multitude of small teeth such as indicated at 90. When the pane 68 is installed in the compartment 84 a rubber cement or the like will be applied to the roughened surface 90 and will serve to hold the pane in position.
To supplement the strength of the bonding material holding the pane 68 in position, the spline element 88 is longitudinally displaced with a sliding motion into the appropriate section of the compartment 84 and this spline element serves not only to further support the pane 68 but moreover to obturate the compartment 84 and to give the mounting of the pane a finished appearance.
The U-shaped channel 58 provides an important feature of the invention in addition to accommodating deviations from perfect dimensions as will be discussed hereinafter. This additional feature takes the form of the opening 92 illustrated in FIG. 3. Opening 92 provides for the drainage of condensed moisture and the like from the interior of the greenhouse construction. Thus the U-shaped channel 58 provides for the double function of drainage and accommodation of dimensional deviations during assembly.
As will be understood from the above description, the bottom perimeter of the framework is slidingly accommodated in one or more U-shaped channels 58. It will also be understood that the vertical peripheries bonding the open side 24 are accommodated in like expansion joints. Similarly the top projection 40 of the greenhouse construction is accommodated in an expansion element 42.
In view of the provision of these expansion elements or joints, the need for assembling the overall construction and framework to precise dimensions is obviated. As a matter of fact, FIG. 3 illustrates a case in which the foot 72 of the framework element 70 is at one lateral extremity thereof spaced before the bottom of the U-shaped channel 58, there being angular displacement therebetween due to the fact that the ground is not perfectly perpendicular to the wall to which the side of the greenhouse construction has been attached.
From the above it will be noted that a greenhouse construction of the invention comprises a framework having one open side and an open bottom, there being provided expansion means to engage the framework adjacent the open side and bottom to support the framework on the ground and to connect the same to an adjacent structure such as a wall of a dwelling. The open bottomed constr-uction avoids the need for the fabrication of a base and at the same time facilitates the utilization of an expansion connection to accommodate deviations in the profile of the ground and its relationship to the said adjacent structure.
It will be noted in FIG. 1 that greenhouses of the invention may be easily provided with doors such as indicated at 94 and louvres such as indicated at 96, such additional features being readily accommodated into the framework construction of the invention Without interferring with the expansion accommodation made with respect to the framework.
It will also be appreciated from what has been stated above that the bottommost expansion device employed to support the lower extremity of the framework will include, for example, a horizontal channel opening in an upward direction and accommodating the insertion of a lower framework element having a channel obturating foot with a breadth corresponding to the internal breadth of the channel.
It will also be appreciated from what has been stated hereinabove that the greenhouse constructions of the invention are readily glazed, the panes of glass being easily insertable into the framework elements described above and being held in position by a bonding agent as well as by a slidably insertable spline element.
There will now be obvious to those skilled in the art many modifications and variations of the construction set forth above. These modifications and variations will not, however, depart from the scope of the invention it defined by the following claims.
