8 Claims. (Cl.273-153) This invention relates to a toy puzzle. More particularly the invention concerns an intriguing peg toy puzzle for finger operation in aligning a multiplicity of apertures ;inoif-set relationship to properly position a multiplicity of pegs in the aligned ofi-set apertures. A feature of the present invention is to provide an intr iguingtoy for children which is easy to understand and simple to operate, yet provides the child with amusement and training in the use of his fingers and exercise of judgment and patience in solving a puzzle toy.

Another feature of this invention is to provide an in- .triguing finger operable peg toy puzzle With multiple pegs zle toy formed of a plurality of apertured blocks in stacked relation about a pivot point and provided with a plurality of finger operable pegs movable into and out of the apertures when properly aligned but self-locking t o prevent complete withdrawal frorn the apertures in the blocks in their stacked relationship.

Further features, objects and advantages will be apparent from the following description of the accompanying drawings.

Figure 1 is a side elevational view of the toy showing extending through aligned openings.

Figure 2 is an explocled perspective of the toy.

Figure 3 is a top plan view of the toy in modified forrn showing an aligned relationship of the parts thereof.

In the following description like parts Will be similarly indicated.

The toy ernbodied in this description includes a multiplicity of stacking blocks which are illustrated by a base section 10, an intermediate section 11 and a top section 12., Bach of the diflerent sections has a plurality of aligned apertures therein in oiT-set relationship and insertable pegs, as hereinafter described.

The base block seotion 10 comprises preferably a rounded block 13 having an upright peg 14 formed therewith or seated and wedged or secured in a centered aperture l5. A plurality of spaced

apertures

16, 17, 18 and 19 are countersunk in seemingly balanced relationship, fromthe peripheral edge of base 10, but actually have about one-sixteenth inch side displacement from the outer periphery of base 10 With respect to their independent relationshipWith one another. These apertures inbloek 10 are cooperatively aligned With the different apertures in

blocks

11 and 12, hereinafter describe'd, and as provided in the arrangement shown in Figure 2.

all of the openings in alignment and with the peg 34 or more 2ipertured'block elements illustrated as preferably the rounded block 21 having the centered aperture 22 therethrough. The aperture 22 permits block 21 to slide over peg 14 and seat on block 13 in a freely pivotal relationship therevvith. A plurality of spaced

apertures

23, 24, 25 and 26 extend all the way through block 21 and are ofl-set in the exact manner as the

countersunk apertures

16, 17, 18 and 19, in base block 10, so that they are aligned when in the relative Position as illustrated in Figure 2.

(I'he top section 12 is preferably a rounded block 28 cf the Same size and general configuration of the

blocks

13 and 21. -I'he block 28 is also provided with a center aperture 29 for pivotally mounting the block 28 on peg 14. A plurality of

apertures

30, 31, 32 and 33 extend throligh the block 28 in a spaced relationship. This relationship exactly corresponds to the spacing and positioning of the like apertures in

blocks

13 and 21 when turned into an aligned position for proper entry of the finger operating sliding or reciprocating keys or pegs 34, 35, 36, and 37, in the manner as hereinafter described. A groove 39 is out into and about the outside peripheral edge 40 of block 28- and holds a peg retaining spring 41. Bach of the

pegs

34, 35, 36 and 37 are provided with a shoulder 43, as illustrated in Figures 1 and 2. Inasmuch as all the Slip pegs, a s herein described are provided Wtih sirnilar shoulderS 43 which operate alike, only' one is described in detail. The shoulder 43is forrnedby reducing or cutting down, for example, the diaineter of the peg 35 at the point 44 adjacent its end 45. The end 45 is of the Same diameter as the Stern portion of the slip peg 35 so that the whole of the peg slides through the

proper apertures

31, 24 and into 17 when they are in proper alignment. As the slip peg 35 and other like pegs are attempted to be Withdrawn from block 28, the spring 41 rides into the reduced diameter portions 44 and locks against sirnilar shoulders 43 in each of the slip pegs as herein described.

When the

blocks

21 and 28 are mounted over upright 14, in the ma imer shown in Figure 1 a cap 45 is glued, wedged or othe'rwise secured over the end of .upright 14. The cap 45 holds the

end sections

10 and 12 in loose fitting or freely pivotal relationship relative to the intermediate section 11. Thus in the illustrated arrangement the

respective end sections

10 and 12 can be independently turned relative to the intermediatesection 11 When the slide pegs 34, 35, 36 and 37 are mounted in block 28 and Withdrwn to the point at which shoulders 43 are locked against complete withdrawal by spring 41. As shown in Figure 1, the slip peg 34 and the balance of the slip pegs, as herein described, are longer than the depth of the aligned apertures in order to provide for finger manipulation.

When the

outside block sections

10 and 12 are mounted with an intermediate sec'tion 11 on a standard or supporting pos t 14 With the relative set or grup of

apertures

30, 23 and 16 in alignment, then the balance of the relative set or group of

apertures

31, 24 and 17, set o1.

group

32, 25 and 18, and set or

group

33, 26 and 19 are also aligned to pr0perly receive the

pegs

34, 35, 36 and 37, respectively. With all {the

pegs

34, 35, 36 and 37 withdrawn until shoulders 43 are engaged by spring 41 in the manner illustrated by.

pegs

35, 36 and 37, as shown in Figure 1, the

blo'ck sections

10, 11 andl2 can be independently rotated to misalign the relative sets or groups of apertures, as described. Ihereafter the problem is to realign all the v relative sets or groups in order t o push the pegs 34 35,

' The intermediate section 11 is representative of one 36 and 37 all the way down into

apert ures

16, 17, 18 and 19, respectively.

As illustrated in the top view shown in Figure 3, the structure therein, represented by top block section 28, is a similar st'acking arrangement, as described, -with the 3 aligned aperture groups o1 sets represented by the

numbers

47, 48, 49 and 50. These aperture sets are drilled as a group in a relatively different oif-set relationship. The aperture gmups representeri by the

nuxnbers

47 and 48 are dri lied in o he body cf the block. secfions ata Sligli tlY greater iiistance vfrbrn the block peripheries than the

aperture groups

53 and 54. The

pegs

51, 52, 53 and 54 are construoted in a manner similar to theheretofore described

pegs

34, 35, 36 and 37, With the exeeption of the stem. sec io.n eing provided witl 1 groeves 55"56 57 and 58, respectiveljr. These

grooves

55, 56, 57 and 58 serve as retaining guides for

pin ends

60, 61, 62 and 63 Which are driven into the side of top section 28',and

spring 41. Whe n one 01 more of the

aperture groups

47, 48, 49 and 50 are not in ali gnment the relative block section or sectidrxs must be turned until realignment is obtained to properlypush each of the

pegs

51, 52, 53 and 54 evenly into the block sections By preventing the withdrawal of the sliding pegs, as described, the relative Positioning of the apertures, as described, cannot be seen. For simplification of the problem ofalignment one of the ets or groups of apertures, for exarnplegroup 47 with its respective peg 51 and pin Stop 60, can be dispensed with and only the rernaining three sets o1 groups of

apertures

48, 49 and 50 drilled in an oflset relationship, to provide the problem of aperture alignrnent for properly reeeiving

pegs

52, 53 and 54 thereinto in the marmer described. Any misalignment of the apertures by rotation of one or more of the apertured block sections will prevent the proper entry of any one or more of the pegs into any one or more of the block sections. Otherwise in the arrangement shown in Figure 2, the block 13 may be a statiqnary base with an upri ght 14 upon which the

seotions

11 and 12 are ielat ively pivotally rnonted for alignment of pegs or

keys

34, 35 36 and 37 in spaced

relative apertures

23, 24, 25 and 26. For economy in manufacture the toy structure described herein is preferably formed of wood. However, it will be re co gnized that the structure can be a molded plastic, metal 0r a,;;ombination of these materials.
