This invention relates to baby cribs and particularly to a crib construction which facilitates the handling of the child from early infancy and particularly from the time it is able to walk.
Such cribs as are now made have relatively high side railings over which the child must be lifted bodily when placing him in or removing him from the crib. When the child has reached a walking age he is frequently so heavy that it is a severe strain on the mother to raise him the necessary distance.
The principal object of my invention therefore is to eliminate this lifting by providing the crib with a passage opening extending from top to bottom of one side railing intermediate its ends, anda step ladder leading to the bottom level of this opening, and arranged when not in use to close the same. The ladder then forms a part of the side railing so that the child cannot crawl or fall out.
A further object is to provide a catch or holding means for the ladder, adapted to function when the ladder is in a raised or passage closing position, which while extremely simple requires both a raising and an inwardmovement of the ladder to engage or release. In this manner there is little possibility of the child being able to release the catch by himself when in the crib.
I have also mounted the ladder so that it may be slid along and held clear of the floor to one side of the opening. This leaves the opening exposed without any obstruction on the floor adjacent the crib and facilitates the work of the mother or nurse in arranging the covers or attending to the wants of the reclining child, since the opening is sufficiently wide to enable her to easily reach through the same instead of over the top of the side railing.
A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purpose for which it is designed.
These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.
In the drawings similar characters of reference indicate corresponding parts in the several views:
Figure 1 is a perspective view of the crib with the ladder lowered and in operative position.
Figure 2 is a similar view showing the ladder raised.
Figure Bis an enlarged fragmentary transverse section showing the ladder raised and before the catch elements are engaged.
Figure 4 is a similar view showing the ladder pressed in at the bottom and further raised to place the catch elements in vertical alinement.
Figure 5 is a similar view showing the position of the ladder when the catch elements are finally engaged.
Figure 6 is a fragmentary top plan View show-' ing the cooperating catch or holding elements on the top rails of the ladder and crib.
Referring now more particularly to the characters of reference on the drawings, the crib in general is of standard form and construction, comprising corner posts and legs I, bottom rails 2 secured to the posts intermediate the ends and forming a support for the springs and mattress, indicated at 3, and top rails 4 also secured to the posts. Vertical bars 5 or the like extend between and connect the top and bottom rails to form the crib enclosing railings.
Inutilizing a structure as above described for the purposes of 'my invention, I cut away a portion of one of the top bars 4 of the corresponding side railing intermediate its ends and between certain of the vertical bars 5, and remove the intervening bars to leave a rectangular opening 6. This opening extends down to the bottom rail 2 and is of sufficient width to permit the free passage of a child therethrough. The ordinary bars 5 at the sides of-this opening are preferably replaced by somewhat heavier bars 5a. The ladder, to close the opening or to extend to the floor from the bottom rail 2 at an outward angle, comprises side rails 1 to fit' between the bars 5a, steps 8 between these rails which are horizontally disposed when the ladder is in a depending position, and an endrail or bar 9 which is at the bottom-0f the ladder when the latter is in its depending position and at the top when the ladder is in position to close the opening 6.
The rail 9 is-of the same cross sectional size and shape as the top rail 4 of the crib so as to match therewith and give the same a continuous unbroken appearance between its cut ends when the ladder is in its raised position. Lugs in project lengthwise from the ends of the rail 9 to fit sockets ll cut in the adjacent ends of the rail l and open to the top of the same. Plates l2 are secured on the front of the rail 9 at its ends and extend beyond the same, so as to engage the front face of the rail 4 and limit the rearward movement of the rail 9 relative thereto before the lugs engage the sockets and thus line the same up vertically.
Projecting lengthwise of the ladder from the ends of the rails l nearest the crib rail 2 are rigid hanger elements I3 having closed slots M in their end portion. A rod I5 slidably projects through the slots, said rod extending parallel to and slightly below the rail 2 for the length of the opening and being secured at its ends on said rail 2 in any suitable manner. This rod extends some distance beyond the opening and this extending portion which is also parallel to the rail 2 is bent near the opening so as to be further out from said rail than the remainder of the rod as plainly shown in Figures 1 and 2. The purpose of this will be shown later.
The slots l4 are of L shape form and are rel-- atively inverted when the ladder is raised so that their horizontal portions then project inwardly relative to the crib from their vertical portions as shown in Figure 3. The rodl5 is normally disposed at the inner end of:the horizontal portion of the slots, and is yieldably held in such position by a fiat spring I6 secured to and depending from the'adjacent step of the ladder and engaging the rod in front. This horizontal portion .of the slot is also so positioned relative to the length of the ladder that when the latter is raised, and said rod is in said horizontal position, the crib and ladder rails 4 and 9 respectively are horizontally alined, as shown in Figure 3. These rails cannot yet become longitudinally alined however since the lugs l0 abut against the outer face of the rail 4- and prevent the necessary inward movement of the rail 9 into place. The length of the vertical portion of the slots I4 however is such thatwhen the rod l5'is at the bottom of such portion, the lugs ID will clear the top of the rail 4, as shown in Figure 4.
In operation therefore to manipulate the ladder so that its top rail may be alined and engaged with the rail .4; it is pressed in at the bottom after it has been turned to a vertical position and against the resistance of the spring IG-(preferably by the knee) until the outer vertical portion of the slots [4 engage the rod. The ladder may then be raised so that the lugs I0 clear the top of the rail 4, after which the rail 9 is shifted inwardly so as to aline with the rail 4. Such inward movement is limited by the engagement of the plates I2 with the rail 4 so that upon then lowering, the
ladder the lugs IIJ alinewith and enter the socketsll. When the ladder is fully lowered into place, therod l5 will be again disposed at the upper end of the vertical portion of the slots l4, and the spring [6 then acts to shift the bottom of the ladder outwardly or so that said rod is again disposed at the inner end of the horizontal portion of the slots. To release the rail 9 from the rail 4 it is necessary to again shift the lower end of the ladder inwardly so that it'can be raised to disengage the catch lugs from their sockets.
If it is desired to use the opening 6 without having the ladder extending to the floor, it is released from its closed position as above described and slid along the crib on the outside to a point beyond the opening while still. maintaining the ladder in an inverted or vertical position. The extended portion of the supporting rod 15 being disposed further out from the crib than the remainder enables the ladder to be thus shifted without interfering :withthe side railing of the crib, as indicated in Figure 5. The rail Sis then in the horizontal plane of the rail 4 transversely of the crib but is outwardly of the same. The ladder may then be releasably maintained in such position by suitable catch means such as cooperating snap catch elements "of theglove fastener type.
It is to be noted that cribs are usually constructed with one side railing mounted for limited vertical movement while the other side railing is fixed. While I have here shown my ladder device as being mounted on the fixed railing, it is immaterial in practice on which of the two railings it is mounted, as will be obvious.
From the foregoing description it will be readily seen that I have produced such a device as substantially fulfills the objects of the invention as set forth herein.
While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may bexresorted to as do not form a departure from. the spirit of the invention, as defined by the appended claims.
Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is:
