Patented Oct. 18, 1949 TUNITED STATES PATENT OFFICEI DOOR GUIDE AND HOLDER Raymond L. Locke, Macon, Ill. Application April 10, 1948, Serial No. 20,239 I 3 Claims.

This invention relates to door guides and holders, and, without limitation thereto, has more particularly to do with one of the kind that, in use, is placed on the floor at the middle of the door opening of a building such as a barn, hangar or the like so as to guidingly receive and hold the meeting lower corner portions of a pair of horizontally sliding, top-hung doors from lateral movement when the doors are closed. That is to say, while the device of the present invention is primarily intended for the above noted particular use, it is adaptable for use with other kinds of doors. For example, it may be used to receive and hold the bottom edge portion of a vertically slidable door in its closed position.

The principal object is to produce a characteristic article of its kind, the protuberance of which, when installed upon the floor, will not cause damage to tires rolling thereover, particularly as when moving an inherently heavy vehicle or a loaded one into or out of the building.

Another and special object is to produce a device of its kind which can be securely fastened in place, particularly on a concrete floor, without the use of bolts, screws, nails or like separate and extraneous fastener elements.

Other objects and advantages to be attained will hereinafter more fully appear in the following description.

Generally stated, the invention consists in making the device substantially shell-like and concave-convex in body form, with rounded outer surface contour and smooth crowned effect vice embeddedly in a concrete floor, door-sill or the like.

A practical adaptation of the invention is illustrated in the accompanying drawings, in which:

Figure 1 is a side elevational view of the device and showing therewith fragmentary lower meeting corner portions of double doors in closed position;

Figure 2 is a view taken at right angles to that of Fi ure 1;

Figure 3 is a section of the device taken on or about the line 3-3 of Figure 1, but with the doors removed and the device shown as embedded in a portion of a concrete floor;

Figure 4 is a perspective view of the device alone; and

Figure 5 is a bottom plan view of the device showing the arrangement of the reinforcing web or rib and the fastener lugs or ears.

Referring now to the drawings in detail, the numeral I0 designates the device of the invention in its entirety. As shown, this device is shell-like and of minimum thickness throughout. In practice the same may be made of metal of ample strength and, obviously, either by a casting process, such as for example, ordinary molding or a die-casting procedure, or else by any approved die-stamping and forming method.

Medially of the device it is provided with an open-ended channel II of rectangular cross-section, that is to say, one having a flat bottom I2 and perpendicular or right-angled side walls I3. This channel I I is to guidingly receive the meeting lower corner portions of a pair of sliding doors I4 when the doors are in closed position as indicated in Figure 1. For this purpose, of course, the channel II will be made to run transversely of the door opening of the building.

It is here noted that while the device is shown as used to receive the meeting lower corner portions of a pair of top-hung, horizontally slidable doors I4, it is to be understood that it may, for example, be used to receive in its channel II the bottom edge portion of a vertically slidable door of the overhead-mounted type.

In any case, the channeled portion II of the device receives the edge portion of a door slidably therein but holds the adjacent portion of the door as thus engaged from lateral movement.

- At each side of the channel I I, the lateral body shell portion I5 of concavo-convex or inverted cupped form, being highest in the middle region of the device and inclining downwardly towards the opposite ends of the channel II and also inclining downwardly laterally from the channel, said body shell portions I5 being of round contour throughout their entire exposed top surfaces and giving a general crowned effect to the device in its protuberance above the normal floor surface. This is an essential and advantageous feature of the present invention in that all abrupt and sharp corners which might cut or cause injury to a vehicle tire riding over the device are eliminated and avoided. This rounded contour ed contour and channeling thereof, further consists in a novel provision for reinforcement of the body shell and means for fastening the device to a floor, door-sill or the like, now to be described in detail.

As shown, the hollow shell-like body In is provided on its underside with a web or rib l6 which crosses under the channel H and terminates adjacent the outer marginsof the lateral body shell portions! 5;" Obviouslythis webbing or ribbing l6 materially stiflens and strengthens the body shell l whose thickness may, therefore, be appreciablyminimized.

For fastening the body shell ID to a floor, sill or other place without using bolts, screws,=nai1s or the like, especially to oneeof concrete; as is the kind more generally in vogue in the present day practice, the body shell I0 is provided with lugs, ears or tongue-like'fastener extensions ll in any desired number and respective locations thereon. As :shown invtheodrawings, there are two of [these-extensions I; provided diametrically oppcsite eaclzt other, one at the outer margin of eachnlateral-body; shellv portion l and in line wit-tr the. transverse bottom; webbing or ribbing l6, said extensions not-:onlyafiording a means of fasteningithedevice-in .place, as-will be presently described; but. also'augmenting the stiffening and reinforcing effect of said webbing or ribbing 16.

With, 'thSaIOllIld) crowned form of the body shell l'lland its-underwebbingor ribbing It and fastener extensionsll thedevice is embedded upon and in a-concrete floor or other place of use by forcing it down-wardupon the body of concrete while the same isstill wet and soft; the body shell Hl itself resting on the-areasof concrete thereunder and its webbing or ribbing [Brand fastener extensions I! taking:;well :into the bodyof the concrete and serving totie 'the-devicein place after the.concrete hasset andhardened'. It is thus apparent that not only does thebody shell Ill-rest throughout its'ow-nmajor extent-on the concrete but its fastening in placezis well: assured by the engagement of the web 'or --rib tend the fastener extensions" which are inserted deeply in the concrete so as -to hold'thedevicefrom lifting as well as lateral movement.

From the foregoing disclosure and" description it 'is apparent that-fa practical and efficient door guide and' holder is produced; which can be manufacturedeconomically and soldat a reasonable price, is easily installedand secured in place withoutusing bolts, screws, nails or other heretofore necessarygseparateand extraneous fastener elements; particularly-where theflooring or means of support for :thedevice is of concrete or a setting and hardening,..plastic or'cementitious material.

In. any-case, regardlessof how'the device is fastened" in :place, or whether it is reinforced as herein-before described; or not, the making of the body shell with the-crowned or inverted cupped and: generally rounded form and surface contour throughout its exposed protuberanceis of particular'advantage in giving ample strength to the device with minimum wall thickness therein, as well as avoiding the possibility of' a vehicle tire becoming damaged in riding over the device.

Whilethe structure illustrated in the accom panying drawings is'that of a practical embodiment of the invention the same is not in limitation thereof, as modifications and changes are possible within'the spirit and scopeof theinvention as delined in the appended claims.

What is claimed is:

1.: A=door guide-and holder of general inverted cupped shell-like body form with rounded surface contour throughout the extent of its protuberance above the normal surface of a floor or supporting base on which the article is mounted, said guide and holder having a transverse channel depressed therein to receive slidably the lower edge portion of a door and for holding the adjacent portion of the door as so received from lateral movement; and an integral reinforcing web or rib and fastener extensions'on'the'underside of said guide and holder both the reinforcing web or rib and fastening extensions adapted to secure the article in'place on the floor or supporting base.
